Description

Technical Field

[0001] This invention relates to an automatic cooking device. Background Technology

[0002] Existing automatic cooking stoves or stir-fry machines typically use a single heat source, meaning a thick-film heating module is installed at the bottom of the cooking pot. However, the heating power of the thick-film heating module is often low and cannot meet the needs of stir-frying. Furthermore, these automatic cooking stoves require a special cooking pot, which cannot be used with ordinary cooking pots in the user's home. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an automatic cooking device that can meet the stir-frying requirements of a dedicated cooking pot while also being applicable to ordinary metal pots in a user's home.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: an automatic cooking device, including a body, a dedicated cooking pot body disposed on the body, a pot body heating module serving as a first heating source disposed in the dedicated cooking pot body, an upper power supply structure electrically connected to the first heating source disposed on the dedicated cooking pot body, a lower power supply structure disposed on the body that can be connected in cooperation with the upper power supply structure, a power board and a control board disposed in the body, the control board being electrically connected to the power board, and the lower power supply structure being electrically connected to the power board, characterized in that: an electromagnetic heating module serving as a second heating source disposed in the body, the electromagnetic heating module being electrically connected to both the power board and the control board, and a magnetic conductive element disposed in the dedicated cooking pot body in conjunction with the electromagnetic heating module, wherein the magnetic conductive element can perform magnetic heating when the electromagnetic heating module is turned on.

[0005] As an improvement, the pot heating module includes a plate made of magnetic metal set at the bottom of the special cooking pot, and a heating element printed on the bottom surface of the plate. The plate is the magnetic element that is matched with the electromagnetic heating module.

[0006] Further improvements include a temperature sensing element at the bottom of the dedicated cooking pot body for measuring the temperature of the pot body. This temperature sensing element is communicatively connected to the control board, which can use the real-time temperature measured by the temperature sensing element to control the operation of the two heating sources to meet different cooking needs.

[0007] As a preferred embodiment, the upper power supply structure is an upper coupler fixed to the bottom of the dedicated cooking pot body, and the lower power supply structure is a lower coupler fixed to the surface of the machine body.

[0008] To facilitate cooking with ordinary metal pots, the upper surface of the lower coupler is flush with the surface of the machine body.

[0009] Further improvements include a control board that determines whether the pot on the machine body is a dedicated cooking pot or a regular metal pot based on whether the upper and lower power-taking structures are coupled. When the upper and lower power-taking structures are coupled, the control board considers the pot on the machine body to be a dedicated cooking pot, and then heats the food in the dedicated cooking pot by controlling the working states of the first and second heating sources. If the lower power-taking structure does not detect the upper power-taking device, it considers the pot on the machine body to be a regular metal pot, and then heats the food in the regular metal pot by controlling the working state of the second heating source.

[0010] Further improvements include a temperature sensing element on the dedicated cooking pot body for measuring the temperature of the pot body, which is communicatively connected to the control board. When the pot body installed on the machine body is a dedicated cooking pot body, the control board obtains the real-time temperature of the dedicated cooking pot body based on the temperature sensing element, and determines the opening and closing of the first heating source and the second heating source based on the real-time temperature.

[0011] When cooking food using the dedicated cooking pot, if the real-time temperature of the dedicated cooking pot is lower than the preset temperature T, the control panel controls the first heating source to turn on and the second heating source to turn off; if the real-time temperature of the dedicated cooking pot is lower than the preset temperature T, and the real-time temperature of the dedicated cooking pot suddenly drops or high-power stir-frying is required, the control panel controls the first heating source and the second heating source to turn on simultaneously; when the real-time temperature of the dedicated cooking pot is greater than or equal to the preset temperature T, the control panel controls the first heating source and the second heating source to turn off simultaneously.

[0012] As a preferred embodiment, the second heating source includes multiple independently configured electromagnetic heating modules; each independent electromagnetic heating module is electrically connected to a control board, and the control board can control the multiple independent electromagnetic heating modules separately.

[0013] As a supplement to the preferred solution, the bottom of the dedicated cooking pot is equipped with multiple temperature sensing elements, each of which is respectively positioned above and below an electromagnetic heating module at a different location. When the pot set on the machine body is a dedicated cooking pot, the control board obtains the real-time temperature at different locations on the bottom of the dedicated cooking pot based on the temperature sensing elements. When the real-time temperature at all locations is less than the preset temperature T, the control board controls the first heating source to turn on and the second heating source to turn off. If the real-time temperature at all locations is less than the preset temperature T, and the real-time temperature at a certain location suddenly drops, the control board controls the first heating source and the electromagnetic heating module corresponding to that location to turn on simultaneously. When the real-time temperature at all locations is less than the preset temperature T, and high-power stir-frying is required, the control board controls the first heating source and the electromagnetic heating modules at all locations to turn on simultaneously. When the real-time temperature at all locations is greater than or equal to the preset temperature T, the control board controls the first heating source and the electromagnetic heating modules at all locations to turn off simultaneously.

[0014] In a further improvement, the surface of the machine body is provided with a panel, on which an operation control module is provided, and the operation control module is electrically connected to the control board.

[0015] Compared with the prior art, the advantages of the present invention are as follows: by setting an electromagnetic heating module in the body, when cooking with a special cooking pot, the food in the special cooking pot can be cooked by combining the first heating source and the second heating source, which can solve the need for stir-frying; while when the user uses an ordinary metal pot, the food in the ordinary metal pot can be cooked by using the second heating source, which is more adaptable.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] Example 1

[0023] like Figures 1-3 The automatic cooking device shown includes a body 1 assembled from a bottom shell 11 and a panel 12. The body 1 has an internal storage space, in which a power board 2 and a control board 3 are installed. The panel 12 has an operation control module 4 electrically connected to the control board 3. The panel 12 has a cooking area, and a lower coupler 5 is installed in the cooking area. The lower coupler 5 is electrically connected to the power board 2. An electromagnetic heating module 6, which serves as a second heating source, is installed on the lower side of the panel 12 corresponding to the cooking area. The electromagnetic heating module 6 is electrically connected to both the power board 2 and the control board 3. The dedicated cooking pot body has a magnetic conductive element that is matched with the electromagnetic heating module. When the electromagnetic heating module is turned on, the magnetic conductive element can generate magnetic heating.

[0024] The automatic cooking device provided in this embodiment requires a dedicated cooking pot body 7. The dedicated cooking pot body 7 contains a pot body heating module that serves as the first heating source. The dedicated cooking pot body 7 has an upper coupler 9 electrically connected to the pot body heating module. The upper coupler 9 can cooperate with the lower coupler 5 to draw power from the pot body heating module. In this embodiment, the dedicated cooking pot body 7 is a double-layered pot body, including an inner pot 71 and an outer pot 72. The pot body heating module directly serves as the base of the inner pot, which includes a plate 8 made of magnetically conductive metal and a heating film 10 printed on the bottom surface of the plate 8. The plate is the magnetically conductive element that matches the electromagnetic heating module 6. A gap is directly provided between the bottoms of the inner pot and the outer pot, and a temperature measuring element 13 for measuring the temperature of the plate 8 is provided in this gap. The upper coupler 9 is fixed to the bottom of the outer pot. The inner pot can be made of stainless steel, and the outer pot can be made of metal or plastic. The temperature measuring element 13 is communicatively connected to the control board 3 through the temperature measuring pin on the upper coupler 9.

[0025] The upper surface of the lower coupler 5 is flush with the surface of the panel 12. When the user does not use the dedicated cooking pot 7 but uses an ordinary metal pot, the ordinary metal pot can be placed directly on the panel 12 which has a cooking area, and the electromagnetic heating module 6 is used to heat the ordinary metal pot.

[0026] The control board 3 determines whether the pot body installed on the machine body is a dedicated cooking pot body or a regular metal pot body based on whether the lower coupler 5 detects the upper coupler 9. When the lower coupler 5 detects the upper coupler 9, it considers the pot body installed on the machine body to be a dedicated cooking pot body 7. At this time, the control board 3 obtains the real-time temperature of the dedicated cooking pot body's base plate based on the temperature sensing element 13. When the real-time temperature is lower than the preset temperature T, the control board controls the first heating source to turn on and the second heating source to turn off. If the real-time temperature is lower than the preset temperature T, and the real-time temperature suddenly drops or high-power stir-frying is required, the control board controls the first heating source to turn off. The first and second heating sources are turned on simultaneously; when the real-time temperature is greater than or equal to the preset temperature T, the control board controls the first and second heating sources to turn off simultaneously; if the lower coupler 5 does not detect the upper coupler 9, but the electromagnetic heating module 6 detects the metal pot, it is assumed that the pot set on the machine body is an ordinary metal pot. At this time, the control board 3 heats the food in the ordinary metal pot by controlling the working state of the second heating source. The specific control method can be based on the heating power or cooking program input by the operation control module 4 to control the second heating source. This control method can use the control logic of the existing induction cooker.

[0027] The automatic cooking device in this embodiment, when using a dedicated cooking pot, can simultaneously utilize the precise temperature control of the first heating source and the rapid heating of the second heating source. That is, it can use the thick-film first heating source for precise temperature control to ensure the consistency of recipes, and it can use the rapid heating of the second heating source to compensate for the low heating power of the first heating source and solve the problem of stir-frying. At the same time, it can also be used with ordinary metal pots in the user's home.

[0028] Example 2

[0029] Unlike Embodiment 1, the second heating source has multiple electromagnetic heating modules 6, and these multiple independently configured electromagnetic heating modules are all located below the cooking area of ​​the panel 12, roughly forming a circle. Each independent electromagnetic heating module is electrically connected to a control board, which can control the multiple independent electromagnetic heating modules separately. (See [link to previous document]). Figure 4 , 5 As shown.

[0030] Multiple temperature sensing elements 13 are installed at the bottom of the dedicated cooking pot body 7, with each element corresponding to an electromagnetic heating module 6 at a different location. When the pot body is a dedicated cooking pot, the control board obtains the real-time temperature at different locations on the bottom of the pot body based on the temperature sensing elements. When the real-time temperature at all locations is lower than the preset temperature T, the control board controls the first heating source to turn on and all electromagnetic heating modules 6 to turn off. If the real-time temperature at all locations is lower than the preset temperature T, and the real-time temperature at a certain location suddenly drops, the control board controls the first heating source and the electromagnetic heating module corresponding to that location to turn on simultaneously. When the real-time temperature at all locations is lower than the preset temperature T, and high-power stir-frying is required, the control board controls the first heating source and the electromagnetic heating modules at all locations to turn on simultaneously. When the real-time temperature at all locations is greater than or equal to the preset temperature T, the control board controls the first heating source and the electromagnetic heating modules at all locations to turn off simultaneously.
