Accordingly, it should be understood that, although steps of various processes or methods may be shown and described as being in a sequence or temporal arrangement, the steps of any such processes or methods are not limited to being carried out in any particular sequence or arrangement, absent an indication otherwise. Indeed, the steps in such processes or methods generally may be carried out in various different sequences and arrangements while still falling within the scope of the present invention.

[0029] Additionally, any references to advantages, benefits, unexpected results, or operability of the present invention are not intended as an affirmation that the invention has been previously reduced to practice or that any testing has been performed. Likewise, unless stated otherwise, use of verbs in the past tense (present perfect or preterit) is not intended to indicate or imply that the invention has been previously reduced to practice or that any testing has been performed.

[0030] Referring now specifically to the drawings, a heater-equipped man-made beehive according to one exemplary embodiment of the present disclosure is illustrated in FIG. 1, and shown generally at broad reference numeral 10. The exemplary beehive 10 incorporates a programmable thermal system 20 utilized to control ambient temperature inside the beehive 10. The present thermal system 20 may be incorporated in beehive 10, as shown and described herein, or may be utilized in any conventional pre-existing hive structure as a retrofit component. In one implementation discussed further below, the present beehive 10 may be heated for periodic treatment cycles to kill or control the presence of invasive pests, such as the Varroa destructor parasite (Varroa mite) and the small hive beetle Aethinatumida (SHB). In other implementations, the exemplary thermal system 20 may be utilized to maintain a sufficiently warm and generally consistent temperature inside the beehive 10 (e.g., at or about 92 degrees F.)particularly during cold winter months.

[0031] Referring to FIGS. 1 and 2, the exemplary beehive 10 is mounted on a wooden base 21 (or pedestal), and comprises an assembly of stacked wooden boxes and other hive structure including: a solid-surface floor board 22, a hive body 23 located on the floor board 22, stacked honey supers 24, 25 located on the hive body 23, an inner cover 26 defining a central feed opening 27, a feeder box 28, and a solid-surface outer cover 29. The box-shaped hive body 23 is constructed of joined side walls 31, 32, 33, and 34, and is sized to mount directly on raised perimeter flanges 36, 37, and 38 of the floor board 22. The front of the floor board 22 is open, and cooperates with a bottom edge of side wall 31 to define a slotted entrance 41 sufficient to allow passage of bees into and from the beehive 10. The joined side walls 31-34 of the hive body 23 form an open top onto which the honey supers 24, 25 are stacked. The honey supers 24, 25 are standard in the industry, and may be shallow, medium or deep sizes. As commonly known and understood in the art, each honey super 24, 25 may contain 8-10 frames (not shown) used to collect honey. Western honeybees collect nectar and store the processed nectar in the honeycomb of the frames. When the honeycomb is full, beekeepers will take the honey supers and extract the honey. During a honey flow, beekeepers may put several honey supers onto a hive so the bees have enough storage space. Honey supers are removed in the fall when the honey is extracted and before the hive is winterized.

[0032] As best shown in FIGS. 2 and 4, the inner cover 26 resides atop the honey super 25 and carries an inverted bucket feeder 45 containing a syrupy mixture of sugar and water. The bucket feeder 45 is located inside the feeder box 28, and has a number of small holes 46 formed in the bucket lid 47 and aligned with the feed opening 27 of the inner cover 26. The small holes 46 allow the syrupy mixture to slowly drip from the bucket feeder 45 through the stacked honey supers 24, 25 to the hive body 23. The outer cover 29 is placed on top of the feeder box 28, and is removable for ready access to the bucket feeder 45. The entire beehive assembly described above may be integrally joined together in substantial vertical (stacked) registration using nails, screws, glue, and other fastener means.

[0033] Beehive Thermal System 20

[0034] In one exemplary embodiment, the thermal system 20 incorporated in the present man-made beehive 10 comprises a removable heating tray 51 and a digital (or mechanical) temperature controller 52. The exemplary heating tray 51 is designed to conveniently slide into and out of the slotted front entrance 41 of the beehive 10, and has a sufficiently low profile to avoid obstructing the passage of bees into and from the hive body 23. Under certain circumstances, an optional entrance reducer 54 may be positioned at the slotted entrance 41 to limit the movement of bees into and from the hive 10.

[0035] Referring to FIGS. 3 and 4, the exemplary heating tray 51 comprises a relatively large planar bottom plate 61 and a smaller planar top plate 62 cooperating to form a conductive pocket for receiving and holding an electric heater pad 63. Both plates 61, 62 may be entirely fabricated of a thin metal, such as aluminum, or other thermally-conductive material. The metal bottom plate 61 covers a substantial portion of the floor board 22 and extends outwardly from the front entrance 41 of the beehive 10, as best shown in FIG. 1. The metal top plate 62 may be sized to correspond substantially to an interior dimension of the hive body 23, such that heat generated by the electric heater pad 63 is conducted across the surface area of the top plate 62 and relatively uniformly distributed throughout the beehive 10. The exemplary heater pad 63 comprises a metal wire heating element 65 laminated between two layers of 20 mil fiberglass-reinforced silicone rubber, and having a power density of 2.5 watts/sq in (0.004 watts/sq mm) and an exposure temperature range of 60 F. to 450 F. (51 C. to 232 C). The exemplary heater pad 63 may also be moisture, chemical, and radiation resistant.

[0036] The present heating tray 51 may further comprise upwardly-turned ears 71, 72 and hand openings 73, 74 to facilitate handling, and a downward-extending mounting flange 75 along its front edge for carrying the electronic temperature controller 52. The temperature controller 52 resides outside of the hive body 23, and is connected to the heater pad 63 through electrical cord 76 and to a power source through outdoor power cord 77. The temperature controller 52 comprises a microprocessor (not shown) and other circuit board components applicable for sensing and automatically regulating temperature of the heater pad 63. A corded temperature probe 78 operatively connects to the temperature controller 52, and has a distal sensor end 79 which inserts through a small hole 81 in the hive body 23 to sense and measure ambient temperature inside the beehive 10. In one exemplary application, the temperature probe 78 functions in a manner similar to a conventional thermostat causing the controller 52 to activate the electric heater pad 63 when the ambient temperature inside the hive 10 drops to a predetermined threshold. In this manner, the interior temperature of the beehive 10 may be constantly monitored and maintained at a predetermined level (e.g., about 92 degrees F.) throughout the winter season.

[0037] In a further exemplary implementation, the beehive thermal system 20 may be utilized in a method for controlling invasive pests inside the beehive 10, such as Varroa mites and small hive beetles mentioned above. In the present method, prior to pest treatment all ventilation openings and seams in the beehive 10 may be sealed using removable foam tape or other suitable insulation. The heating tray 51 is then activated during a pest treatment cycle to raise and maintain the ambient temperature inside the hive body 23 to greater than 100 degrees F.e.g., about 106 degrees F. Once the ambient temperature reaches 106 degrees F. (the treatment temperature), a single treatment cycle may last for between 120 and 180 minutes at this maintained temperature. In one embodiment, each treatment cycle lasts 160 minutes. After the treatment cycle is completed, the ventilation openings are uncovered and the heating tray 51 is de-activated to reduce the ambient temperature inside the hive body 23 back to its normal maintenance temperaturee.g., about 92 degrees F. In one example, the treatment cycles may be performed at least three times annually; once in each of the spring, summer, and fall seasons.

[0038] In alternative embodiments (not shown), the exemplary man-made beehive may incorporate a flexible thermal blanket designed to wrap 360-degrees around an exterior of the hive box. The thermal blanket may be battery-powered, and may operatively connect to a solar panel for charging. The thermal blanket functions to maintain a constant ambient temperature of about 92 degrees F. to promote a large healthy hive.

[0039] For the purposes of describing and defining the present invention it is noted that the use of relative terms, such as substantially, generally, approximately, and the like, are utilized herein to represent an inherent degree of uncertainty that may be attributed to any quantitative comparison, value, measurement, or other representation. These terms are also utilized herein to represent the degree by which a quantitative representation may vary from a stated reference without resulting in a change in the basic function of the subject matter at issue.

[0040] Exemplary embodiments of the present invention are described above. No element, act, or instruction used in this description should be construed as important, necessary, critical, or essential to the invention unless explicitly described as such. Although only a few of the exemplary embodiments have been described in detail herein, those skilled in the art will readily appreciate that many modifications are possible in these exemplary embodiments without materially departing from the novel teachings and advantages of this invention. Accordingly, all such modifications are intended to be included within the scope of this invention as defined in the appended claims.

[0041] In the claims, any means-plus-function clauses are intended to cover the structures described herein as performing the recited function and not only structural equivalents, but also equivalent structures. Thus, although a nail and a screw may not be structural equivalents in that a nail employs a cylindrical surface to secure wooden parts together, whereas a screw employs a helical surface, in the environment of fastening wooden parts, a nail and a screw may be equivalent structures. Unless the exact language means for (performing a particular function or step) is recited in the claims, a construction under 35 U.S.C. 112(f) [or 6th paragraph/pre-AIA] is not intended. Additionally, it is not intended that the scope of patent protection afforded the present invention be defined by reading into any claim a limitation found herein that does not explicitly appear in the claim itself.
