However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of the layers and regions may be enlarged, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0031] Combination Figures 1 to 4 As shown, according to a specific embodiment of the present application, a grilling machine is provided.

[0032] The grilling machine comprises: a grilling pan assembly 10 and a temperature bag assembly 20. The grilling pan assembly 10 comprises a grilling pan 11; the temperature bag assembly 20 comprises a temperature bag 21 and a capillary tube 22, one end of the temperature bag 21 is connected to the capillary tube 22, and the surface of the temperature bag 21 facing the grilling pan 11 is completely arranged to fit the bottom surface of the grilling pan 11.

[0033] By applying the technical solution of the utility model, the surface of the temperature bag 21 facing the baking tray 11 is completely fitted to the bottom surface of the baking tray 11, so that the temperature bag assembly 20 and the baking tray 11 are tightly fitted, and the change of the baking tray temperature can be sensed in time, thereby improving the temperature sensing efficiency and temperature sensing accuracy of the frying and grilling machine, thereby achieving accurate control of the actual working temperature of the frying and grilling machine to the user's set temperature.

[0034] Combination Figure 1 As shown, a heat expansion medium is arranged in the temperature bag 21, and the first end of the capillary 22 is connected to the inside of the temperature bag 21; the temperature bag assembly 20 also includes a temperature control body 30, a metal sheet is arranged inside the temperature control body 30, the metal sheet abuts against the outlet of the second end of the capillary 22, and the temperature control body 30 is electrically connected to the heating element, so that the temperature control body 30 controls the opening and closing of the heating element according to the pressure value of the metal sheet when the heat expansion medium expands or contracts. The metal sheet abuts against the outlet of the second end of the capillary 22, so the volume expansion generated by the heat expansion medium when heated will cause the pressure on the metal sheet to increase. That is, the temperature bag assembly 20 of the present application provides a liquid expansion type temperature controller, by setting the surface of the temperature bag 21 facing the side where the baking tray 11 is located to be completely fitted with the bottom surface of the baking tray 11, so that the temperature sensing of the grilling machine is more rapid and accurate, and effectively prevents the heating element from continuing to heat after the baking tray 11 reaches the set temperature or stopping heating when the baking tray 11 does not reach the set temperature.

[0035] The liquid expansion thermostat is a device that uses the expansion of liquid to control temperature. It consists of a sealed container and a temperature bulb filled with a specific liquid. When the temperature bulb is heated, the liquid expands, causing the pressure in the container to increase, thereby triggering the thermostat switch and controlling the operation of the heating system to maintain the set temperature range.

[0036] Specifically, the temperature control body 30 controls the opening and closing of the heating element according to the pressure value applied to the metal sheet when the heat expansion medium expands or contracts, which can be designed by engineers according to actual conditions. For example, the temperature bag can control the operation of the thermostat by opening a silver contact through the expansion of the medium after being heated, or a membrane box is provided in the temperature control body 30, and the membrane box is connected to the temperature bag 21. The membrane box expands or contracts with the medium, and the switch is driven on and off by the lever principle to achieve the purpose of constant temperature or precise temperature control. The temperature control body can also control the opening and closing of the heating tube according to the pressure value applied to the metal sheet. For example, a frying and grilling machine has three gears: high heat, medium heat, and low heat, and the temperature corresponding to medium heat is 175 degrees Celsius. When the baking tray is heated to 175 degrees Celsius by the heating tube, the medium in the temperature bag expands and provides a pressure value to the metal sheet. If the pressure value is less than the standard pressure generated by the medium at 175 degrees Celsius, it indicates that the temperature of the baking tray is insufficient, and the heating element is kept in working state; if the pressure value is greater than the standard pressure generated by the medium at 175 degrees Celsius, it indicates that the temperature of the baking tray is too high, and the heating element is immediately switched to the off state.

[0037] Furthermore, the temperature bag 21 is an arc-shaped structure. By setting the temperature bag 21 as an arc-shaped structure, the heat expansion medium in each part of the temperature bag 21 is heated evenly and quickly, thereby improving the temperature sensing efficiency and temperature sensing accuracy of the grilling machine.

[0038] Depending on the medium in the temperature bag, the temperature detection range of the temperature bag assembly 20 can be between 20 degrees Celsius and 500 degrees Celsius.

[0039] Specifically, the baking tray assembly 10 further includes a heating element connected to the baking tray 11, and the curvature of the temperature package 21 is the same as the curvature of at least part of the heating element. The technical solution of this embodiment is adopted to improve the convenience of arranging the temperature package 21.

[0040] Furthermore, the grilling machine further includes a fixing assembly 40, through which the temperature bag 21 is connected to the grilling pan 11, and the fixing assembly 40 includes: a mounting seat 41 and a locking member 42. The mounting seat 41 is connected to the grilling pan 11, and the temperature bag 21 is installed in the mounting seat 41; the locking member 42 is arranged close to the mounting seat 41, and the locking member 42 has a locking position for locking the temperature bag 21 in the mounting seat 41. There is at least one locking member 42, and when there are multiple locking members 42, the multiple locking members 42 are arranged at intervals along the length direction of the mounting seat 41. Figure 2 There are two locking members 42 shown in the figure. The fixing assembly 40 adopts the above solution. On the one hand, it ensures the reliability of the connection between the temperature bag 21 and the baking tray. On the other hand, it has the advantages of convenient installation, easy replacement and disassembly.

[0041] like Figure 1As shown, the mounting seat 41 is provided with a clamping groove 411 on both end side walls along the length direction, and the capillary 22 enters the mounting seat 41 through one of the two clamping grooves 411 .

[0042] Optionally, the end of the temperature bulb 21 away from the capillary tube 22 may also be clamped through the clamping groove 411 .

[0043] Furthermore, a mounting groove is provided on one side of the mounting seat 41 away from the baking tray 11, and the temperature package 21 is installed in the mounting groove, and the shape of the mounting groove is adapted to the shape of the temperature package 21. The mounting groove can protect the temperature package 21 from external factors, improve its temperature sensing accuracy, and extend its service life.

[0044] It should be noted that, in order to ensure that the surface of the temperature bag 21 facing the baking tray 11 is completely fitted with the bottom surface of the baking tray 11, the installation groove is a through groove that penetrates along the height direction.

[0045] like Figure 2 As shown, the locking member 42 includes: a fixing column 421, a fixing plate 422, and a fixing bolt 423. The fixing column 421 is protruding from the bottom of the baking tray 11, and a threaded hole is provided inside the fixing column 421; a through hole is provided at one end of the fixing plate 422, and the other end of the fixing plate 422 is extended toward the mounting seat 41 so that the fixing plate 422 covers at least part of the mounting groove; the fixing bolt 423 is sequentially inserted into the through hole and the threaded hole. Through the cooperation of the fixing column 421, the fixing plate 422, and the fixing bolt 423, the temperature bag 21 can be prevented from being separated from the mounting groove, and at the same time, by adjusting the fixing bolt 423 and the fixing plate 422, the close contact between the temperature bag 21 and the baking tray 11 can be ensured.

[0046] Furthermore, the height of the bottom plane of the fixing column 421 is flush with the height of the bottom plane of the mounting seat 41. With this solution, the bottom structure support of the grilling machine can be made more stable and firm, and the placement of the fixing sheet 422 is also convenient.

[0047] Furthermore, a heat expansion medium is arranged in the temperature bag 21, and the heat expansion medium includes at least one of mercury, xylene, methanol, glycerin, and ethanol.

[0048] The expansion coefficients of the above substances are as follows: mercury (0.181×10^-3 / ℃), xylene (11×10^-4 / ℃), methanol (11.8×10^-4 / ℃), glycerol (5.1×10^-4 / ℃), ethanol (1.12×10^-3 / ℃). The corresponding temperature test range of the above substances can reach up to 550 degrees Celsius.

[0049] Furthermore, a heating mounting portion 111 is protruding from the bottom of the baking tray 11, and an annular groove is formed inside the heating mounting portion 111, and the heating element is arranged in the annular groove. This solution can improve the heating efficiency of the heating element and avoid the interference of the heating element on the temperature induction of the temperature bag.

[0050] In an optional embodiment, the heating element is an annular structure, and cross-shaped ribs are arranged inside the heating element.

[0051] like Figure 4 A knob 50 for adjusting the temperature is also shown in the figure, and the user can rotate the knob 50 to control the working temperature of the grill.

[0052] Optionally, the capillary is made of metal material.

[0053] Optionally, the diameter of the capillary tube is smaller than the diameter of the temperature bulb.

[0054] In an optional embodiment, the cross-sections of the temperature package at various locations along the direction of the vertical axis are arranged to be the same.

[0055] According to the technical solution of the present application, the core component of the liquid expansion thermostat is composed of an expansion material filled with a liquid having a high thermal expansion coefficient. This material will expand when the temperature rises, thereby pushing the temperature bag and the liquid in the conduit to expand, and applying an expansion force of different strengths to the metal sheet of the temperature control body. The temperature bag is set on the bottom of the baking tray to adjust the different temperatures of the baking tray, and fits tightly to timely sense the changes in the baking tray temperature. The temperature bag and the liquid in the conduit respond immediately, making the cooking equipment highly efficient and accurate in sensing temperature. Among them, an installation groove is provided at the bottom of the baking tray for installing the temperature bag, which is directly attached to the bottom of the baking tray to sense the real-time temperature of the baking tray; the baking tray assembly is provided with a fixing assembly for fixing the temperature bag, which is beneficial to the connection stability of the temperature bag.
