DESCRIPTION OF PREFERRED EMBODIMENTS

(11) FIG. 1 shows a first exemplary embodiment of the device according to the invention. The device comprises a vessel 1 having an electronic unit 11, a unit for obtaining a temperature 12, and a first sensor 15, as well as a mobile sensor unit 2 having a second sensor 22 and a lifting basket 3. Sensors of the type NTC, linear PTC, platinum R, semiconductors and IC's are suited, in particular, as the first and second sensors 15, 22.

(12) The vessel 1 preferably has a base part 10, which is also referred to as a base, and a container-accommodating body 13 extending above this base part 10. The container-accommodating body 13 is preferably cylindrical and has an interior 14, which is open toward the top, for accommodating a container 5 for baby food.

(13) In this example, the container 5 is a baby bottle having a bottle body and a bottle neck 50, onto which the nipple is placed for administering food. The container 5 can be placed directly into the interior 14. The lifting basket 3 is preferably used for this purpose, however. The lifting basket comprises an accommodating part 30 for holding the container 5, and a handle 31 for the easy use of the basket.

(14) The electronic unit 11 and the unit for obtaining a temperature 12 are preferably situated in the base part 10. The unit for obtaining a temperature 12 is a unit, which is known in the prior art, for heating or—depending on the embodiment—for cooling the interior 14 or a fluid located therein. Preferably, the temperature-control unit is formed by an electric heating coil or an electric heating plate. A suitable energy source, e.g., a battery, or an electric connector for an electric mains is present in the base part.

(15) The first sensor 15 is situated in the interior 14. The sensor is connected to the electronic unit 11 wirelessly or via a line and transmits measurement data to this electronic unit 11. The electronic unit 11 is connected to the unit for obtaining a temperature 12 in order to control the performance of raising or lowering a temperature, in particular the heating performance, in accordance with the temperature values measured by the first sensor 15 and/or the second sensor 22.

(16) The sensor unit 2 comprises the second sensor 22 and a sensor head 20 having a first diameter, and a sensor rod 21 having a second diameter. The first diameter is preferably greater than the second diameter.

(17) The second sensor 22 is situated on the end of the sensor rod 21 that does not have a sensor head. The sensor rod is inserted into the baby food or contacts a surface of the baby food and thereby measures its temperature. The measured values are then transmitted either wirelessly or via cable to the electronic unit.

(18) An adapter part 4 holds the sensor unit 2 in a desired position. The adapter part 4 has a through-hole, through which the sensor rod 21 is passed. The sensor head 20 rests on the adapter part 4 and is thereby held by the adapter part. As a result, the second sensor 22 extends into a zone which is spaced from the walls of the container, and can optimally determine the temperature of the baby food. The adapter part 4 is fastened on the container neck 50. Preferably, the adapter part is screwed thereon or inserted thereon.

(19) The adapter part 4 preferably enables the second sensor 22 to be held in at least two stable positions. This is advantageous when different sizes of containers are used. The adapter part 4 is preferably formed from multiple parts. In this example, the adapter part is formed from two parts. Said adapter part comprises a fastening body 41, preferably a threaded ring, and a spacer 40. The spacer 40 essentially consists of a hollow cylinder and an end-face, outwardly extending flange. The adapter part 4 is preferably produced from plastic.

(20) The shape of the adapter part 4 changes, depending on how the spacer 40 is connected to the threaded ring 41. In FIG. 1, the container 5 is a relatively small baby bottle. The spacer 40 is oriented with the flange pointing downward. The threaded ring clamps the flange between itself and the container neck 50. The hollow cylinder of the spacer 40 extends upward and thereby lengthens the container 5. The sensor head 20 rests on the spacer 40, and the lower free end of the sensor rod 21 terminates as a distance from the walls of the container 5, in its interior 51.

(21) A large container is depicted in FIG. 2. The adapter part 4 is configured differently in this case. The flange of the spacer 40 points upward, wherein the flange is therefore clamped between the threaded ring 41 and the upper end face of the container neck 5. The hollow cylinder of the spacer 40 now points downward, however. The sensor head 20 therefore rests on the threaded ring. In this case as well, the free end of the sensor rod 21 terminates at a distance from the walls of the container 5.

(22) FIGS. 3 and 4 show the mobile sensor unit 2. In FIG. 3, it is apparent that the sensor unit, preferably the sensor head 20, can be provided with at least one display. In this example, an acoustic signal generator 23 is present, which indicates the attainment of a predefined temperature of the baby food and/or reports disturbances. The reference numbers 24 refer to optical displays. The optical displays can be, for example, different-colored LEDs which display the operating state, the progress of the heating, and the attainment of the predefined temperature of the baby food. It is also possible, of course, that the sensor unit 2 comprises a display having temperature information and/or diagrams of the heating progress. The same applies in the case of cooling.

(23) Different types of baby food are depicted in FIGS. 5 to 8. FIGS. 5 and 6 show the position of the second sensor 22 which has been inserted into the container 5, in the case of a frozen baby food M.sub.1, M.sub.2. In this case, the sensor head 20 does not rest on the spacer 40 or the threaded ring 41, since the free end of the sensor rod 21 has already been resting on the frozen surface. During the thawing of the baby food, the sensor rod 21 slides downward, along the adapter 4, until the sensor head 20 comes to rest again and the free end of the sensor rod 21 is surrounded by the baby food. This situation is apparent in FIGS. 7 and 8.

(24) FIG. 9 shows one variant of the exemplary embodiment according to FIG. 1. Instead of an energy source integrated in the sensor unit 2, or instead of a power cable between the sensor unit 2 and the vessel 1, an induction module 6 is present. The vessel 1 is provided with a corresponding first induction coil 60, and the sensor unit 2 is provided with a second induction coil 61. If the sensor unit 2 is located in the vessel 1 and if the vessel 1 is activated, the sensor unit 2 is supplied with electric energy and the second sensor 22 can carry out the necessary measurements. In addition, a transmitting means 7 for transmitting temperature information, and a smart device 8 for receiving temperature information are depicted in the base 10. These can also be used without an induction module 6. In addition, the transmitting means 7 can be additionally designed as a receiving means, in order to receive, for example, information and parameters from the smart device 8 or another information source. Information on the desired temperature or on the container used, for example, can be transmitted.

(25) The device according to the invention is utilized as follows. A heatable fluid, preferably water, is filled into the interior 14 of the container-accommodating body 13. Alternatively, the vessel can also be designed, for example, for heating or cooling the interior by means of air that has been brought to a certain temperature. Preferably, the fill volume of the interior as well as the volume of the baby food are known, and these data can be entered directly into the electronic unit or can be directly detected by the electronic unit, for example, by an integrated scale. The volume of the fluid for raising or lowering a temperature, which has been added, preferably approximately corresponds to the volume of the baby food.

(26) If the device is now switched on, both sensors 15, 22 measure the corresponding temperatures, wherein the temperature of the baby food is referred to in the following as T.sub.M, and the temperature of the fluid for raising or lowering a temperature is referred to as T.sub.W. The electronic unit calculates, preferably by means of a controller contained therein, a weighted temperature mean value corresponding to the ratio of the volumes of the two measuring media
T.sub.Regulator=(x*T.sub.M+y*T.sub.W)/2.

(27) By means of this mean value T.sub.Regulator, the unit for obtaining a temperature is now regulated and the heating performance or, if necessary, the cooling performance, is adjusted accordingly. If only the measured values from one of the two sensors is used for the control, the calculation of the mean value is dispensed with, and the measurement data from the one sensor are utilized either directly or averaged over a period of time.

(28) The device according to the invention and the method according to the invention make it possible to bring baby food to a certain temperature in a manner that is gentle, yet efficient.
