DETAILED DESCRIPTION OF THE INVENTION

(19) The configuration of one embodiment of this invention is shown in FIGS. 1-3. A water tank sits at the top of the machine and a filter basket is located underneath the water tank. A cup, mug or glass carafe or thermal jug is placed underneath the filter basket. In one embodiment, only one button is required to turn on and off the machine.

(20) In one embodiment, a body (110) supports one or more cold water chamber or water supply chamber (101) which is connected to the hot water chamber (102). In between these chambers (101) & (102), there is a piston valve (104) that controls water flow from the cold water chamber (101) to the hot water chamber (102). The default position of this piston valve (104) opens a flow path from the cold water chamber (102) to the hot water chamber (101) but closes a flow path from the hot water chamber to the filter basket. A user pours cold water into the cold water chamber directly or via the top lid (109) and the cold water fills up all the chambers up to a maximum level. In another embodiment, there is only the hot water chamber (102) and water is poured directly into the hot water chamber.

(21) In one embodiment, the machine is turned on by pressing an On/Off button. The heating system (103) will be turned on to heat up the cold water in the hot water chamber. An electronic temperature sensor built in the hot water chamber (102) monitors the water temperature. When the water reaches the optimal temperature, the heating system (103) will be turned off. The motor gear system (113) will begin to rotate the gear system (115). In one embodiment shown in FIGS. 4-6, the gear system (115) is designed with 2 separated cams, cam 1 is for activating the micro switch (114) and cam 2 is for activating the valve piston (104). Once the gear system (115) rotates to a proper position, cam 1 will activate the micro switch, the motor gear system (113) will stop rotating, and cam 2 on top of the gear system (115) will push the piston valve upwards at the same time. The flow path between the hot water chamber (102) and the filter basket (105) is thus opened and the heated water would flow gradually from the hot water chamber (102) through the pour over system (116) to the filter basket (105). Once all the heated water goes to the filter basket (105) and the hot water chamber (102) becomes empty, the electronic temperature sensor will detect a drop in temperature that re-activates the motor system (113) and gear system to restore the gear system (115) back to the default position, i.e. the piston valve (104) will open a flow path between the cold water chamber (101) and the hot water chamber and close the flow path between the hot water chamber (102) and the filter basket to allow cold water to fill up the hot water chamber (102) for the next batch of heating up or brewing.

(22) The filter basket (105) includes a pause and serve valve (106) that enables liquid beverage to be stored in the basket (105). When the valve (106) is pushed open by the container (107), the liquid beverage (e.g. coffee or tea) would flow through the valve (106) into the container (107). The container may be a cup, mug or glass carafe or thermal jug. A keep warm heater (108) built inside of the keep warm plate (111) can be placed underneath the container (107) if a warming feature is required. The keep warm heater (108) is covered by a bottom cover (112).

(23) The lid (109) placed on top of the water chambers is to cover the water chambers when the machine is in operation.

(24) The heating system (103) can be any type of heating system generally known in the art. Similarly, any power can be used in the heating system according to what is known in the art.

(25) The gear system (115) and motor gear system (113) can be produced in any kind of material. The main function of these gear systems is to open the piston valve (104). Moreover, cam 1 at the gear system and the micro switch act as a signal for the gear systems to turn on and off.

(26) FIG. 7 shows an embodiment of the pour over system (116). In one embodiment, the pour over system is located in between the hot water chamber(s) and the filter basket. In one embodiment, the pour over system comprises at least one dispensing channel (117), which guide(s) the flow of water from the hot water chamber to the filter basket, and at least one drain hole (118) that allows the flow of water to be dispensed and spread all over the coffee grounds in the filter basket. This ensures the ground coffees is mostly or completely wet, warmed, steeped and extracted. In one embodiment, the dispensing channel is contained in a circular piece. In another embodiment, the flow of the water in the dispensing channel can be in circular or any distributing forms. In one embodiment, the heated water is delivered to reach every surface or spot of ground coffee in the filter basket via the plurality of drain holes at the bottom surface of the pour over system. This is to ensure all surfaces or spots of ground coffee in the filter basket are well contacted with water. In one embodiment, each dispensing channel has at least one drain hole.

(27) The pour over system is to replicate hot water pouring on ground coffee by a system instead of a person. The pour over system helps to improve some common inconsistencies with manual pour over, among them disorganized and inconsistent pours, and irregular extraction.

(28) The pour over system (116) can be produced in any kind of material and shape. The main function of the pour over system is to distribute and spread heated water all over the coffee grounds in the filter basket.

(29) In one embodiment, the pour over system (116) has at least one dispensing channel (117) with at least one drain hole (118). The dispensing channel (117) can be in any size or any shape.

(30) One of ordinary skill in the art would readily configure the filter basket (105) to fit for any size or any shape of filters or tea container.

(31) In the present invention, a cup, mug or glass carafe or thermal jug can be used as the container (107). When a glass carafe is used, a separated heating system may be required for the keep warm feature.

(32) FIG. 5 shows clearly how to operate (open and close) the piston valve (104) when an optimal temperature is reached in the hot water chamber. In one embodiment, the default position of the valve piston (104) opens the flow path from cold water chamber to hot water chamber (101) but closes the flow path from the hot water chamber (102) to filter basket (105) (FIG. 5A). Under this condition, water can fill up both water chambers. After the machine is turned on, the heating system (103) will heat up the cold water in the hot water chamber (102). In one embodiment, an electronic temperature sensor built in the hot water chamber (102) would monitor the water temperature. When the water reaches an optimal temperature, the heating system (103) will be turned off. The motor gear system (113) will begin to rotate the gear system (115). Once the gear system rotates to a proper position and activates the micro switch by a cam of the gear system, the gear system will stop the motor gear system (113) from rotating (FIG. 5B) and another cam on top of this gear system (115) will push the piston valve upward. This opens the flow path between the hot water chamber (102) and filter basket (105) and closes the flow path between the cold water chamber (101) and hot water chamber (102), i.e. hot water can flow out of the hot water chamber to the filter basket but cold water from the cold water chamber cannot flow into the hot water chamber to prevent the dilution of the hot water by the cold water.

EXAMPLE

(104) FIG. 8 shows an isometric view of an embodiment of this invention. The coffee maker comprises a water tank (1) on a top housing (2) connected to a bottom housing (3) via a plurality of connecting elements (4) to form a space between the top housing (2) and bottom housing (3) to house a carafe (5). At the bottom of the top housing is a rotating spout (6) to imitate manual pouring of hot water into the carafe. The carafe (5) comprises an upper part having a brewing cone (51) and a lower part for receiving brewed coffee. Coffee ground is placed inside the brewing cone and hot water from the rotating spout will pour over and percolates the coffee ground. The water tank (1) comprises a heating system, a valve and a temperature sensor, wherein when the temperature sensor detects water temperature in the water tank reaches a specified temperature, the heating system is turned off and the valve is opened to allow hot water to flow to the brewing cone via the rotating spout. FIG. 9 is a cross-section of the coffee maker showing the spatial relationship of these components.

(105) FIG. 10 shows the mechanism for controlling the rotating spout (6). A rotate spout drive motor (61) drives a rotate spout drive gear (62) which in turn drives a rotate spout gear (63) to cause the spout to rotate when the rotate spout drive motor (61) is turned on.

(106) FIGS. 11A and B show a system (7) controlling water supply to the spout comprising a spout valve drive motor (71) for driving a spout valve cam (72) that pushes on a spout valve lever (73) to act on a spout valve body to control water flow.

(107) Actions of the heating system, valve system and rotating spout system are closely correlated so that water to a specified temperature in the water tank will be promptly released into the coffee ground in a manner similar to manual pour over.

(108) FIGS. 12A to D show how the plurality of connecting elements connects to the top housing and lower housing. Each top or bottom housing will have a plurality of holes corresponding to each of the plurality of connecting elements. Each connecting element will have a hook-like feature (41) to be inserted into each of the holes in the top or bottom housing. Within the top or bottom housing is a piece of interlock (21, 31) that can be moved to fit nicely into the space inside the hook (4) of the connecting elements to lock them in place. This design removes the need for using a mould for the housing so that it is cheaper and easier to produce. The type of materials that can be chosen for the housing can be easily varied, for example, wooden strips can be used as the plurality of connecting elements. This will not be possible with conventional coffee maker designs. Due to the spacing between each connecting element, light can shine through the housing into the carafe and a user can observe the brewing process clearly.
