It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this utility model will not be described separately.

It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0034] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0035] like Figure 1 and Figure 2 As shown in the figure, this utility model embodiment provides an automatic heating device 1 for the receiving tray of a cooking machine. This device can be mainly used to transfer the dishes output by the cooking machine. That is, after the cooking machine finishes cooking the dishes, the dishes can be received by this device and transferred to another container for storage or for subsequent processing, display, or consumption by users.

[0036] like Figure 3 As shown, the automatic heating device 1 for the serving tray of the cooking machine includes a serving tray 11, a placement rack 12, a heating element 13, and a control element 14. The serving tray 11 can be a container or plate, or other utensil used for receiving food. The placement rack 12 is located adjacent to or connected to the cooking machine, and at least one placement position 121 is formed on the placement rack 12 for placing the serving tray 11, thus facilitating its access and placement. The heating element 13 is disposed on the placement rack 12 corresponding to the placement position 121 to heat the serving tray 11 located at the placement position 121. The control element 14 is electrically connected to the heating element 13, thereby controlling the heating element 13 to turn on heating and maintain the heating frequency.

[0037] Optionally, the placement position 121 may be provided with structural features such as a groove or a base, or with information such as markings, text, or patterns, so that users can identify the position of the placement position 121. One or more placement positions 121 may be formed on the placement rack 12. When multiple placement positions 121 are formed, the formation methods of each placement position 121 may be the same or different.

[0038] Specifically, the control unit 14 can control the heating element 13 in various ways. For example, in the first embodiment, when the receiving tray 11 is placed in the placement position 121, the damping effect of the receiving tray 11 can cause a change in the resonant frequency of the circuit where the heating element 13 is located, generating a current pulse. At this time, the control unit 14 can determine whether the receiving tray 11 is placed in the placement position 121 by the pulse change signal emitted by the heating element 13, and control the heating element 13 to turn on or off according to the position of the receiving tray 11. In the second embodiment, the control unit 14 can be connected to the software of a terminal device such as a mobile phone, which can detect whether the receiving tray 11 is placed in the placement position 121 and send an presence signal to the control unit 14.

[0039] In both of the above implementation schemes, when the control element 14 detects that no receiving tray 11 is placed on the placement position 121, it controls the heating element 13 to turn off, thereby preventing the heating element 13 from continuously heating and causing safety hazards, and also saving energy. When the control element 14 detects that a receiving tray 11 is placed on the placement position 121, it controls the heating element 13 to turn on, thereby accurately heating the receiving tray 11 on the placement position 121.

[0040] In the third embodiment, the control element 14 can use a preset heating temperature, which can include a maximum preset temperature and a minimum preset temperature. When the receiving tray 11 is heated to the maximum preset temperature, the heating element 13 is automatically turned off; when the receiving tray 11 cools down to the minimum preset temperature, the heating element 13 is automatically turned on. In this way, the control element 14 can control the heating element 13 to repeatedly turn on and off at a certain frequency according to the temperature change of the receiving tray 11, so as to keep the temperature of the receiving tray 11 within the preset temperature range. Optionally, the aforementioned preset temperature range can be set to 60-260℃, that is, the temperature of the receiving tray 11 can be maintained within the range of 60-260℃. This temperature range is usually close to the temperature when the food is finished cooking, thus better maintaining the temperature of the food when receiving it, preventing the food from cooling down when it comes into contact with the receiving tray 11, and preserving the quality of the food to the greatest extent. Of course, the preset temperature range can also be set to 80-200℃. Within this temperature range, the temperature of the receiving plate 11 is kept at the same level as the temperature of the freshly cooked dish, preventing the dish from cooling down due to excessively low temperature or burning due to excessively high temperature, thus better maintaining the temperature and quality of the dish.

[0041] In the fourth implementation scheme, the control unit 14 can also control the heating element 13 to turn on or off based on time information. Specifically, the control unit 14 can control the heating element 13 to turn on for a specified time based on the heating time specified by the user or automatically set by the program, and then control the heating element 13 to automatically turn off after the required heating time has been reached. For example, the user or relevant detection program can set the control unit 14 to start the heating element 13 before the dish is finished, based on the time required for the cooking machine to finish cooking the dish. This allows the heating element 13 to preheat the receiving plate 11 until the dish is finished, thus enabling the dish to be directly transferred to the heated receiving plate 11 upon completion, thereby reducing waiting time and improving the efficiency of dish preparation and serving.

[0042] Through the above process, the control unit 14 can automatically control the heating element 13, reliably maintain the temperature of the receiving tray 11, prevent the receiving tray 11 from cooling down, and the heating process of the receiving tray 11 does not require manual operation, making it convenient to use. Of course, the control method of the control unit 14 on the heating element 13 is not limited to the above-mentioned schemes, and the specific design can be flexibly adjusted according to actual needs.

[0043] The automatic heating device 1 for the receiving tray of the cooking machine provided in this embodiment includes a receiving tray 11, a placement rack 12, a heating element 13, and a control element 14. By electrically connecting the control element 14 to the heating element 13, the control element 14 can automatically control the heating element 13, causing it to repeatedly turn on and off at a certain frequency. This maintains the temperature of the receiving tray 11 within a suitable range, ensuring it is at a suitable temperature for receiving food. This effectively prevents the food from cooling down upon contact with the receiving tray 11, thus affecting its texture and preserving its quality. Furthermore, by setting the control element 14, the heating element 13 can be automatically turned on or off, eliminating the need for manual operation during the heating process. Therefore, the automatic heating device 1 for the receiving tray of the cooking machine has a high degree of intelligence, is easy to use, and effectively solves the problem of the receiving tray's low temperature affecting the texture of the food. It also features a simple structure and good practicality.

[0044] In some embodiments, such as Figure 3 As shown, the automatic heating device 1 for the receiving tray of the cooking machine also includes a position detection element 15, which is disposed on the placement rack 12 to detect the position of the receiving tray 11. The control element 14 is electrically connected to the position detection element 15 to at least obtain the detection signal emitted by the position detection element 15.

[0045] Specifically, the position detection component 15 is used to detect whether the receiving tray 11 is placed on the placement position 121 and sends the detection signal to the control component 14. After the control component 14 receives the detection signal sent by the position detection component 15, it can automatically control the heating component 13 according to the placement of the receiving tray 11.

[0046] In some embodiments, such as Figure 3 As shown, the automatic heating device 1 for the receiving tray of the cooking machine also includes a temperature detection element 16, which is disposed on the placement rack 12 to detect the temperature of the receiving tray 11. The control element 14 is electrically connected to the temperature detection element 16 to at least obtain the detection signal emitted by the temperature detection element 16.

[0047] Specifically, after the temperature detection element 16 detects the temperature of the receiving tray 11, it sends the detection signal to the control element 14. After the control element 14 receives the detection signal sent by the temperature detection element 16, it can compare the current temperature of the receiving tray 11 with the preset temperature range to determine whether the heating element 13 needs to be turned on for heating.

[0048] It is understandable that the automatic heating device 1 of the vegetable receiving tray of the cooking machine can be equipped with only one of the position detection element 15 and the temperature detection element 16, or it can be equipped with both the position detection element 15 and the temperature detection element 16 at the same time, which can be flexibly designed according to actual needs.

[0049] Optionally, when multiple placement positions 121 are formed on the placement rack 12, one heating element 13 can be provided for each placement position 121, thereby facilitating the control of turning the heating element 13 on or off according to the situation of different placement positions 121. Similarly, one position detection element 15 and one temperature detection element 16 can also be provided for each placement position 121. Of course, the above components can be flexibly adjusted according to different types, for example, as Figure 3 As shown, a single position detection element 15 can also be used to simultaneously detect whether multiple placement positions 121 have a receiving tray 11 placed there. The above design only needs to achieve the same detection and heating effects for each placement position 121.

[0050] Optionally, the heating element 13 can take the form of electromagnetic heating, infrared heating, heating plate heating, heating wire heating, or hot air heating, etc.; the position detection element 15 can take the form of electromagnetic induction detection, tactile switch detection, proximity sensor detection, metal detection, or infrared beam detection, etc.; and the temperature detection element 16 can take the form of infrared temperature measurement, NTC (Negative Temperature Coefficient thermistor) sensor temperature measurement, thermocouple temperature measurement, or heating timing conversion, etc. In this embodiment of the present invention, there are no special limitations on the specific forms of the heating element 13, position detection element 15, and temperature detection element 16, and they can be flexibly designed as needed. As an example, the heating element 13 can be an electromagnetic induction coil, the position detection element 15 can be an electromagnetic sensor, and the temperature detection element 16 can be an NTC sensor.

[0051] In some embodiments, such as Figure 4 and Figure 5 As shown, a receiving groove 122 is provided on the side wall of the placement rack 12, and at least one placement position 121 is formed within the receiving groove 122. The heating element 13 can be arranged corresponding to the inner wall of the receiving groove 122. With this design, the receiving tray can be placed in the receiving groove 122, thereby isolating it from the external environment through the inner wall of the receiving groove 122, providing a certain degree of protection for the receiving tray, reducing the problem of collision between the receiving tray and the outside environment, and improving the stability of the receiving tray when placed and heated. Moreover, this design can also reduce the space occupied by the receiving tray, and the overall structure is simple and aesthetically pleasing.

[0052] In some embodiments, such as Figure 3 and Figure 4As shown, multiple receiving slots 122 can be spaced apart along the height direction, thereby utilizing the space in the height direction to place more receiving trays 11, resulting in high space utilization. Of course, it is understood that when multiple receiving slots 122 are provided, they can be provided not only along the height direction but also along the horizontal direction, and the specific design can be flexibly made according to the site conditions and requirements.

[0053] In some embodiments, such as Figure 6 and Figure 7 As shown, at least a portion of the heating element 13 is disposed in the placement rack 12 along the height direction and located on the upper inner wall of the receiving groove 122 to heat the receiving tray 11 placed upside down in the receiving groove 122. Specifically, the receiving tray 11 does not necessarily need to be placed upright in the receiving groove 122; it can also be placed upside down in the receiving groove 122. This placement method provides better stability for receiving trays 11 with certain shapes. In addition, when some receiving trays 11 have residual moisture after washing, the upside-down placement method facilitates the drainage of moisture. When the receiving tray 11 is placed upside down in the receiving groove 122, the heating element 13 only needs to be disposed on the upper inner wall of the receiving groove 122 to heat the bottom of the receiving tray 11. This design is easy to implement.

[0054] It is understood that one or more placement positions 121 can be formed within the receiving groove 122, for example, in Figure 4 and Figure 5 In the embodiment shown, a placement position 121 is formed within a receiving groove 122, while Figure 6 and Figure 7 In the embodiment shown, two placement positions 121 are formed within a receiving groove 122, which allows for a more flexible design.

[0055] In some embodiments, such as Figure 1 As shown, the placement rack 12 includes a protrusion 123 and a step 124. The protrusion 123 extends along the height direction, and the step 124 is connected to the protrusion 123 at an angle. The protrusion 123 and the step 124 together form at least one placement position 121. At least a portion of the heating element 13 is disposed on the protrusion 123 and / or the step 124 to heat the placement position 121 formed by the protrusion 123 and the step 124.

[0056] Specifically, when placing the receiving tray 11, such as Figure 1As shown, the receiving tray 11 can be placed on the placement position 121 formed by the protrusion 123 and the step 124, so that the bottom of the receiving tray 11 contacts the surface of the protrusion 123 and the circumferential side of the receiving tray 11 abuts against the surface of the step 124, thereby making the receiving tray 11 stable. The receiving tray 11 can be heated by the heating element 13 provided on the protrusion 123 and / or the step 124.

[0057] Optionally, the heating element 13 can be provided only on the protrusion 123. The heating element 13 provided on the protrusion 123 can heat the bottom position of the receiving tray 11, resulting in higher heating efficiency. Of course, the heating element 13 can also be provided only on the step 124, or it can be provided on both the protrusion 123 and the step 124, as long as it can provide heating at the position where the receiving tray 11 contacts the placement rack 12.

[0058] In some embodiments, such as Figure 8 As shown, the automatic heating device 1 for the receiving tray of the cooking machine also includes a stop 17, which is connected to the protrusion 123 and / or the step 124 to limit the receiving tray 11 to the placement position 121 formed by the protrusion 123 and the step 124. Optionally, the stop 17 can be implemented in various ways, for example, in Figure 8 In the illustrated embodiment, the stop 17 can be configured as a frame, which is connected to the protrusion 123 and forms a space to accommodate the receiving tray 11, thereby limiting the position of the receiving tray 11. Of course, the stop 17 can also be configured in other forms, such as a limiting protrusion, a gripper, a hook, etc., as long as it can achieve the limiting function by contacting the receiving tray 11.

[0059] The above embodiment limits the receiving tray 11 by setting the stop 17, which can better prevent the receiving tray 11 from loosening during placement and heating, and has a good protective effect, improving the stability of the receiving tray 11.

[0060] In some embodiments, such as Figure 1 and Figure 9 As shown, the sidewall of the protrusion 123 connecting to the step 124 is inclined toward the side away from the step 124, and the sidewall of the step 124 connecting to the protrusion 123 is inclined toward the side away from the protrusion 123. Specifically, as... Figure 9As shown, taking the interface A where the protrusion 123 connects to the step 124 as a reference, the protrusion 123 and the step 124 are inclined to opposite sides from interface A, so that the connection between the protrusion 123 and the step 124 is at a lower position. With this arrangement, the receiving tray 11 can be held between the protrusion 123 and the step 124 under the action of gravity, thereby effectively preventing the receiving tray 11 from sliding outward and improving the stability of the receiving tray 11 during placement and heating.

[0061] In the above embodiment, both the protrusion 123 and the step 124 are inclined. Of course, it is also possible to only incise the protrusion 123 or only incise the step 124, which also improves the placement stability. In addition, the above-mentioned scheme of incising the protrusion 123 and / or the step 124 can be combined with the scheme of setting the stop 17 for limiting, thereby further improving the placement stability of the receiving tray 11.

[0062] In some embodiments, such as Figure 1 As shown, the side walls of the protrusion 123 on both sides are respectively connected to stepped portions 124, and the protrusion 123 and the corresponding stepped portion 124 form at least one placement position 121. Optionally, the stepped portions 124 can be symmetrically arranged on both sides of the protrusion 123, which improves the structural aesthetics. Of course, the stepped portions 124 on both sides of the protrusion 123 can also be asymmetrical, as long as the placement position 121 can be formed.

[0063] It is understood that the placement positions 121 can be formed in the same or different ways on the same placement rack 12. That is to say, the solutions such as opening the receiving groove 122, setting the protrusion 123 and the step 124 described in the above embodiments can be applied to the same placement rack 12, which has a high degree of design flexibility.

[0064] This utility model also provides a cooking machine, including a main body and the above-mentioned automatic heating device 1 for the receiving tray of the cooking machine. The placement rack 12 can be connected to the main body or integrally formed, or it can be set apart from the main body, so as to facilitate the cooking machine to quickly transfer the food to the receiving tray after the food is cooked.

[0065] The cooking machine provided by this utility model, by adopting the aforementioned automatic heating device 1 for the receiving tray, prevents the food from cooling down rapidly and affecting its taste when transferring it, resulting in better food output quality. Furthermore, the heating of the receiving tray 11 is automatically controlled by the control unit 14, requiring no manual operation, thus maintaining the cooking machine's ease of use.

[0066] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
