Technical Field

[0001] This utility model relates to the field of electric heating appliances, specifically an electric heating appliance. Background Technology

[0002] Current electric heating appliances are similar to electric tea stoves, with structures like the bidirectional water outlet tea stove described in Chinese patent document CN202220489206.5. This structure mainly includes a base and a kettle body. A lower coupler is installed on the base, containing a water inlet pipe. The kettle body, needing to achieve bottom water inlet, is made entirely of glass. A stainless steel heating plate is installed at the bottom of the kettle body, connected to an upper coupler that couples with the lower coupler. The upper coupler contains a water inlet valve connected to the water inlet pipe. This structure results in a kettle body that is not transparent or aesthetically pleasing due to the glass body and heating plate being joined together. Furthermore, the weight of the kettle body, including the heating plate and upper coupler, increases when lifting or placing it, making it more difficult for the user. Additionally, the heating plate needs to integrate a water inlet (or outlet), a temperature sensor, and a water level detection device, further affecting the aesthetics of the kettle body.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1:

[0028] See Figures 1 to 5 As shown, an electric heating appliance includes a base 1 and a kettle body 2 integrally formed from glass material. The kettle body 2 is placed on the upper side of the base 1, and a handle 3 is connected to the side wall of the kettle body 2. A lower coupler 4 is provided on the base 1, and a water inlet pipe 5 is provided in the lower coupler 4. A water pump 6 connected to the water inlet pipe 5 is provided inside the base 1. An upper coupler 7 is provided at the bottom of the handle 3 and is coupled to the lower coupler 4. A water valve core 8 is provided in the upper coupler 7 and is connected to the water inlet pipe 5 when coupled. A water passage structure 9 is provided on the handle 3 and is connected to the inner cavity of the kettle body 2. The water valve core 8 is connected to the water passage structure 9.

[0029] The kettle body 2 of this motor-driven heating appliance is made of glass material through a one-piece firing process. Therefore, the coupling structure is set at the bottom of the handle 3, so that the bottom of the glass kettle can remain intact and be de-heated from the heating element 17. In addition, the kettle body 2 can achieve automatic water filling or automatic water dispensing functions by cooperating with the upper and lower couplers 4, eliminating the need to lift the kettle to pour water. The operation is simple and the use is more convenient. Furthermore, the water inlet and outlet, as well as the temperature sensing or water level detection device, can be hidden inside the handle 3, so that the glass kettle body 2 remains transparent and beautiful.

[0030] The water passage structure 9 includes an inlet / outlet pipe 91. The rear end of the inlet / outlet pipe 91 is connected to the water valve core 8 via a first pipe body 92. The inlet / outlet pipe 91 is located at the bottom of the handle 3 and its front end is connected to the bottom of the kettle body 2. The inlet / outlet pipe 91 is connected to the water pump 6 via the water valve core 8, so that the kettle body 2 can control the operation of the water pump 6 to draw clean water from the outside into the inner cavity of the kettle body 2 to achieve an automatic water filling function, or the water in the kettle body 2 can be heated and hot water can be drawn out to achieve an automatic water dispensing function.

[0031] In addition, the top of the kettle body 2 is provided with a spout, and a lid is provided on the spout. Consumers can pour water directly into the kettle body 2 through the spout. Alternatively, if there is water in the kettle body 2, the kettle body 2 can be disassembled and the water poured out through the spout.

[0032] The lower coupler 4 is provided with a lower conductor 41, which is electrically connected to the control circuit board 10. The control circuit board 10 is placed inside the base 1. The upper coupler 7 is provided with an upper conductor 71 that is electrically connected to the lower conductor 41 during coupling. The upper conductor 71 is electrically connected to the electrical device, which is placed inside the handle 3 or on the kettle body 2.

[0033] By utilizing the cooperation of the upper and lower conductors 41, the upper coupler 7 and the lower coupler 4 not only function as connectors for water flow, but also serve as conductive communication devices, allowing detection elements to be installed on the kettle body 2 or the handle 3. This ensures that the function of the kettle body 2 remains unchanged compared to traditional structures.

[0034] The electrical components include a temperature sensor 11 and / or a water level detection probe 12. The temperature sensor 11 and / or the water level detection probe 12 are connected to the water passage structure 9 and electrically connected to the lower conductor 41 through its lead wire. The water passage structure 9 can draw water out of the kettle body 2 and detect the water temperature in the handle 3 through the temperature sensor 11. The water level detection probe 12 can detect whether there is no water or a low water level in the kettle body 2.

[0035] Specifically: The water passage structure 9 includes a connecting pipe 93, the longitudinal pipe of the connecting pipe 93 forms an inlet and outlet water pipe 91, and the two ends of the transverse pipe of the connecting pipe 93 respectively form installation ports 931, one installation port 931 is connected to a temperature sensor 11, and the other installation port 931 is connected to a water level detection probe 12. The sensing ends of the temperature sensor 11 and the water level detection probe are arranged facing each other, and it also includes an inlet interface 94 integrally connected to the transverse pipe, which is connected to the water passage valve core 8;

[0036] This structure can connect the temperature probe 11 and the water level detection probe 12 to the water path between the inlet / outlet pipe 91 and the water valve core 8. On the one hand, it is completely hidden inside the handle 3, and on the other hand, the flowing water can improve the accuracy of detection. The temperature probe 11 and the water level detection probe 12 can be fixed to the connecting pipe 93 by a threaded structure or a snap-fit ​​structure.

[0037] The upper and lower parts of the pot body 2 are provided with a neck ring 201, and a retaining clamp 13 is fitted onto the neck ring 201. The retaining clamp 13 has a first connecting hole 131. The handle 3 has a second connecting hole 301 corresponding to the first connecting hole 131. It also includes a bolt 14 and a nut 15. The bolt 14 passes through the first connecting hole 131 and the second connecting hole 301 in sequence and is locked with the nut 15 to assemble and connect the handle 3 to the pot body 2. The neck ring 201 encircles the glass pot body 2, so that the handle 3 can be fixed to the pot body 2.

[0038] In this embodiment, a central through hole 141 is provided in the bolt 14 at the bottom of the kettle body 2, and an opening 202 is provided at the bottom of the kettle body 2 corresponding to the central through hole. The water inlet and outlet pipes 91 pass through the central through hole 141 and the opening 202 in sequence and are connected to the inner cavity of the kettle body 2. A sealing ring 16 is also provided between the water inlet and outlet pipes 91 and the kettle body 2. Through the connection structure between the kettle body 2 and the handle 3, the water inlet and outlet pipes 91 can also be fixed at the same time.

[0039] The base 1 is provided with a kettle body positioning part 101. The base 1 is provided with a heating element 17 corresponding to the kettle body positioning part 101. The heating element 17 can be a heating plate, heating wire, heating film or heating core, etc. The kettle body 2 is placed on the upper side of the heating element 17 and forms a detachable connection with the base 1. The kettle body positioning part 101 is concave and adapted to the bottom shape of the kettle body 2, which can position the kettle body 2 and prevent the kettle body 2 from being pushed, pulled or slid.

[0040] A handle positioning part 102 is provided on one side of the kettle body positioning part 101. The bottom of the handle 3 cooperates with the handle positioning part 102, and the lower coupler 4 is provided at the bottom of the handle positioning part 102. The handle positioning part 102 can ensure that after the kettle body 2 is placed in place on the kettle body positioning part 101, the lower coupler 4 and the upper coupler 7 can be quickly coupled, thereby improving installation efficiency.

[0041] The water pump 6 is provided with a first port 61 and a second port 62. The first port 61 is connected to the water inlet pipe 5, and the second port 62 is connected to the second pipe body 63. The base 1 is provided with a water outlet 18, which is connected to the second pipe body 63. The water drawn out of the kettle body 2 can be discharged through the water outlet 18, so that consumers do not need to lift the kettle to pour water, making the operation more convenient. Example 2:

[0042] See Figure 6 and Figure 7 As shown, the water passage structure 9 includes an inlet pipe 95 in addition to the inlet and outlet pipes 91. The rear end of the inlet pipe 95 is connected to the water valve core 8 through the first pipe body 92. The first pipe body 92 is inserted into the handle 3. The inlet pipe 95 is located at the top of the handle 3 and its front end is connected to the upper part of the kettle body 2.

[0043] This structure enables water to flow from the top of the handle 3 in the kettle body 2. The structure of the inlet and outlet pipes 91 is basically the same as in Embodiment 1. The difference is that the connecting pipe 93 does not have an inlet port 94. It is only used to introduce water from the kettle body 2 into the connecting pipe 93 and to supply the temperature sensor 11 and the water level detection sensor 12 for detection. Therefore, in Embodiment 2, the electric heating appliance only has an automatic water dispensing function. Example 3:

[0044] Example 3 differs from Example 2 in that: See Figure 6 As shown, the water pump 6 is provided with a first port 61 and a second port 62. The first port 61 is connected to the water inlet pipe 5, and the second port 62 is connected to a second pipe body 63. The second pipe body 63 extends out of the base 1. Since the second pipe body 63 extends out of the base 1, it can be used as a water pumping pipe or as a book pipe, which is suitable for use when the electric heating appliance has automatic water supply and automatic water discharge functions.
