Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a cooking appliance and a testing method. Background Technology

[0002] Currently, when users place food into cooking appliances such as ovens, steamers, and microwave ovens, they generally place it within the pre-marked cooking area. The temperature measuring device is usually located on the side wall of the appliance. However, the effective temperature measuring field of view of the temperature measuring device on the side wall does not completely match the marked cooking area. Even if the food is placed in the cooking area, only a small part may be within the effective temperature measuring field of view, resulting in reduced accuracy of temperature measurement and thus affecting the cooking effect. Summary of the Invention

[0003] Embodiments of this application provide a method for detecting an electrical appliance, a control device for an electrical appliance, an electrical appliance, and a computer-readable storage medium.

[0004] The cooking appliance of this application includes a housing, a base plate, a light source, and a temperature sensor. The housing and the base plate enclose a cooking space. The light source and the temperature sensor are disposed within the cooking space. The light source emits indicator light to a preset cooking area within the cooking space. The temperature sensor is used to collect temperature information. The first field of view of the temperature sensor coincides with the second field of view of the light source.

[0005] The detection method of this application is applied to a cooking appliance, which includes a housing, a base plate, a light source, and a temperature sensor. The housing and the base plate enclose a cooking space, and the light source and the temperature sensor are disposed within the cooking space. The temperature sensor is used to collect temperature information, and the first field of view of the temperature sensor coincides with the second field of view of the light source. The detection method includes: controlling the light source to emit an indicator light towards a preset cooking area within the cooking space; and acquiring the temperature information collected by the temperature sensor.

[0006] In the cooking appliance and detection method of this application, an indicator light is emitted by a light source whose second field of view coincides with the first field of view of the temperature sensor to indicate the actual position where the object to be cooked should be placed, instead of being placed directly in a preset cooking area. When the object to be cooked is placed according to the indicator light, it is only necessary to ensure that the indicator light covers the surface of the object to be cooked so that the object to be cooked is within the first field of view of the temperature sensor. The temperature sensor can obtain all the infrared light emitted by the object to be cooked to collect temperature information, thereby ensuring the accuracy of the temperature sensor in measuring the temperature of the object to be cooked, and thus ensuring the cooking effect.

[0016] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0017] Please see Figure 1 The cooking appliance 100 of this application includes a housing 10, a base plate 20, a light source 30, and a temperature sensor 40. The temperature sensor 40 and the light source 30 are located within a cooking space 50. The housing 10 and the base plate 20 together form the cooking space 50. The light source 30 emits indicator light to a preset cooking area S within the cooking space 50; the temperature sensor 40 is used to collect temperature information, and the first field of view 41 of the temperature sensor 40 coincides with the second field of view 31 of the light source 30.

[0018] In the cooking appliance 100 and detection method of this application, an indicator light is emitted by a light source 30 whose second field of view 31 coincides with the first field of view 41 of the temperature sensor 40, to indicate the actual position where the object to be cooked 200 should be placed, instead of being placed directly in the preset cooking area S. When the object to be cooked 200 is placed according to the indicator light, it is only necessary to ensure that the indicator light covers the surface of the object to be cooked 200 so that the object to be cooked 200 is within the first field of view 41. The temperature sensor 40 can obtain all the infrared light emitted by the object to be cooked 200 to collect temperature information, thereby ensuring the accuracy of the temperature measurement of the object to be cooked 200 by the temperature sensor 40, and thus ensuring the cooking effect.

[0019] Please refer to it again. Figure 1 The cooking appliance 100 will be described in further detail below:

[0020] The cooking appliance 100 includes a housing 10, a base plate 20, a light source 30, a temperature sensor 40, a heater 60, and a controller 70. The housing 10 and the base plate 20 together form a cooking space 50. The light source 30 and the temperature sensor 40 are located within the cooking space 50.

[0021] The cooking appliance 100 can be a microwave oven, oven, steamer, etc. This application uses an oven as an example to illustrate the concept. The principle is basically the same when the cooking appliance 100 is other types of appliances, and will not be described in detail here.

[0022] The outer casing 10 includes a top wall 11 and a side wall 12. The top wall 11 and the bottom plate 20 are disposed opposite to each other, and the side wall 12 is disposed on the bottom plate 20.

[0023] The outer casing 10 has a door 13 (not shown). In one example, the door 13 is opened in the side wall 12 to form a side door; in another example, the door 13 is opened in the top wall 11 to form a top door. The door 13 can be opened and closed to open or close the cooking space 50. By opening the door 13, the user can put the object to be cooked 200 (such as ingredients, utensils for holding ingredients, etc.) into the cooking space 50.

[0024] The side wall 12 is also provided with a mounting groove 121, in which the light source 30 and the temperature sensor 40 are both installed.

[0025] Optionally, when the user places the object to be cooked 200 into the cooking space 50, indicating that cooking can begin, the controller 70 can turn off the light source 30 that instructs the user to place the object to be cooked 200, thus avoiding unnecessary power consumption.

[0026] The outer casing 10 is also equipped with a control component 14, such as a knob. The control component 14 can set the cooking temperature and send the cooking temperature to the controller 70. The controller 70 controls the heater 60 to stop heating when the heater 60 heats the object to be cooked 200 until the temperature sensor 40 detects that the temperature of the object to be cooked 200 has reached the cooking temperature, thereby achieving constant temperature heating and improving the cooking effect. When the cooking temperature is set to 0 by the control component 14, it means that heating will no longer occur. At this time, the controller 70 can immediately control the heater 60 to stop heating, thereby achieving control over the cooking process.

[0027] The base plate 20 is disposed opposite to the top wall 11 of the outer casing 10. The base plate 20 is used to support the object to be cooked 200. A preset cooking area S enclosed by marking lines is formed on the base plate 20. The preset cooking area S can be the range covered by the first field of view 41 of the temperature sensor 40 on the base plate 20, or the preset cooking area S can be the range covered by the second field of view 31 of the light source 30 on the base plate 20; or the preset cooking area S can be the range covered by the first field of view 41 and the second field of view 31 on the base plate 20, which is the overlapping area M of the two.

[0028] It is understandable that, since the temperature sensor 40 is located on the side wall 12, the first field of view 41 does not completely cover the area directly above the preset cooking area S, but rather covers the preset cooking area S at an angle (e.g., ...). Figure 1 As shown), therefore, when the height of the object to be cooked 200 is relatively high, such as Figure 2 As shown, even if the object to be cooked 200 is placed within the preset cooking area S, most of the object to be cooked 200 may be located outside the second field of view 31, and the object to be cooked 200 is only located on the side within the first field of view 41. The ingredients contained in the object to be cooked 200 are generally located in the center of the object to be cooked 200. Therefore, the temperature detected by the temperature sensor 40 is very inaccurate at this time.

[0029] Therefore, at this time, the user places the object to be cooked 200 according to the indicator light, so that the surface of the object to be cooked 200 is illuminated by the indicator light as much as possible, such as... Figure 3 As shown, the central area of ​​the upper surface of the object to be cooked 200 is located within the first field of view 41. The temperature sensor 40 can accurately detect the temperature information of the food placed in the central area of ​​the upper surface of the object to be cooked 200, thereby improving the accuracy of temperature measurement.

[0030] The light source 30 is installed in the mounting slot 121 opened in the side wall 12. The light-emitting surface of the light source 30 faces the cooking space to emit indicator light to the cooking space. It can be understood that the indicator light is visible light and can be seen by the user.

[0031] Temperature sensor 40 is disposed in mounting slot 121 opened in side wall 12. The light-receiving surface of temperature sensor 40 can face cooking space 50 to receive infrared light within the first field of view 41. It is understood that infrared light is invisible light.

[0032] The first field of view 41 of the temperature sensor 40 may coincide with the second field of view 31 of the light source 30, including the first field of view 41 of the temperature sensor 40 may partially or completely coincide with the second field of view 31 of the light source 30.

[0033] Please see Figure 1 In one embodiment, the temperature sensor 40 and the light source 30 can be arranged side by side, and the first field of view 41 can at least partially overlap with the second field of view 31. The smaller the distance between the light source 30 and the temperature sensor 40, the larger the overlapping area M. The preset cooking area S is located in the overlapping area M, such as the preset cooking area S being the area covered by the overlapping area M on the base plate 20.

[0034] In this embodiment, the light source 30 and the temperature sensor 40 are connected and arranged side by side, thereby maximizing the overlap area M between the first field of view 41 and the second field of view 31. When the user places the object to be cooked 200 according to the indicator light, it is only necessary to ensure that the object to be cooked 200 is completely covered by the indicator light, or covers the central area of ​​the upper surface as much as possible, so that the infrared light emitted by the object to be cooked 200 can be basically received by the temperature sensor 40, thereby ensuring the accuracy of the temperature sensor 40 in detecting the temperature of the object to be cooked 200.

[0035] Please see Figure 4 Optionally, the cooking appliance 100 may also include a reflector cup 80. The reflector cup 80 is disposed on the side wall 12, with its opening 81 facing the preset cooking area S. The light source 30 and the temperature sensor 40 are both disposed at the bottom of the reflector cup 80. The reflector cup 80 is used to adjust the first field of view 41 of the temperature sensor 40 and the second field of view 31 of the light source 30 to further increase the overlap area M of the first field of view 41 and the second field of view 31.

[0036] Optionally, the light source 30 and the temperature sensor 40 are disposed in the reflector cup 80 and are disposed side by side at the end of the reflector cup 80 away from the opening 81 (i.e., the bottom of the reflector cup 80). The light-receiving surface of the temperature sensor 40 and the light-emitting surface of the light source 30 both face the opening 81 of the reflector cup 80. The size of the opening 81 of the reflector cup 80 can be determined according to the overlapping area M of the first field of view 41 and the second field of view 31. For example, the area covered by the opening 81 of the reflector cup 80 of the first field of view 41 and the second field of view 31 is the overlapping area M. That is to say, the light outside the overlapping area M in the second field of view 31 of the light source 30 is reflected into the overlapping area M by the reflector cup 80, while the light outside the overlapping area M in the first field of view 41 of the temperature sensor 40 cannot enter the reflector cup 80. Thus, the actual field of view of the light source 30 and the actual field of view of the temperature sensor 40 almost completely overlap, that is, they are both overlapping areas M, which maximizes the indication effect of the indicator light on the cooking object 200.

[0037] Please see Figure 5 Optionally, the reflector cup 80 includes a first reflective surface 82 and a second reflective surface 83. The first reflective surface 82 and the second reflective surface 83 are arranged opposite to each other. The first reflective surface 82 is arranged opposite to the light source 30 to reflect the indicator light emitted by the light source 30 to form a second field of view 31. The second reflective surface 83 is opposite to the temperature sensor 40. Infrared light (specifically, infrared light located within the first field of view 41) is reflected by the second reflective surface 83 and converges towards the temperature sensor 40. The reflector cup 80 is also provided with a fixing frame 84, which is located at the bottom of the reflector cup 80. The light source 30 and the temperature sensor 40 are respectively arranged on opposite sides of the fixing frame 84, so that the light source 30 emits indicator light towards the first reflective surface 82, and the temperature sensor 40 faces the second reflective surface 83 to receive the infrared light reflected by the second reflective surface 83.

[0038] The curvature of the first reflective surface 82, the curvature of the second reflective surface 83, the angle of the light-emitting surface relative to the first reflective surface 82, and the angle of the light-receiving surface relative to the second reflective surface 83 can be adjusted to adjust the overlapping area M of the first field of view 41 and the second field of view 31, thereby making the overlapping area M of the first field of view 41 and the second field of view 31 as large as possible, and maximizing the indicating effect of the indicator light on the cooking object 200.

[0039] Please see Figure 5Optionally, the cooking appliance 100 may also include a lens 91, which can transmit not only infrared light but also indicator light. The lens 91 is located at the opening 81 of the reflector cup 80 to seal the reflector cup 80, thereby preventing gases generated by the heating of the object to be cooked 200 in the cooking space 50 from affecting the light source 30 and temperature sensor 40 inside the reflector cup 80, and ensuring the service life and accuracy of the light source 30 and temperature sensor 40.

[0040] Optionally, the lens 91 can also seal the opening of the mounting groove 121 opened in the side wall 12, thereby ensuring that the light source 30 and temperature sensor 40 in the mounting groove 121 are not affected by the gas generated by the heating of the object to be cooked 200 in the cooking space 50, and ensuring the service life and accuracy of the light source 30 and temperature sensor 40.

[0041] Optionally, please refer to Figure 6 The cooking appliance 100 may also include a light filter 92. The light filter 92 may also be disposed within a mounting groove 121 formed in the side wall 12. The light filter 92 is a semi-transparent, semi-reflective device, capable of transmitting infrared light while also reflecting indicator light. The light filter 92 may be disposed within a first field of view 41. Infrared light within the first field of view 41 passes through the light filter 92 and is received by the temperature sensor 40. Light emitted by the light source 30 is reflected by the light filter 92 to form a second field of view 31.

[0042] Thus, by setting a filter 92 in the first field of view 41 to transmit infrared light, while adjusting the second field of view 31 of the light source 30, the overlapping area M is made as large as possible.

[0043] Alternatively, please see Figure 7 The filter 92 is a semi-transparent and semi-reflective device. The filter 92 can not only transmit indicator light, but also reflect infrared light. The filter 92 is disposed within the second field of view 31. The light emitted by the light source 30 passes through the filter 92 to form the second field of view 31. The infrared light within the first field of view 41 is reflected by the filter 92 and received by the temperature sensor 40.

[0044] Thus, by setting a filter 92 in the second field of view 31 to allow the indicator light to pass through, the first field of view 41 of the temperature sensor 40 is adjusted, thereby making the overlapping area M as large as possible.

[0045] Please refer to it again. Figure 1 The outer casing 10 also includes a bottom wall 15, which is disposed opposite to the base plate 20. A side wall 12 is disposed on the bottom wall 15. The bottom wall 15, the side wall 12 and the base plate 20 form an installation space 16, and the heater 60 is disposed within the installation space 16.

[0046] The heater 60 may include a microwave antenna 61 and a magnetron 62. The magnetron 62 generates microwave signals, which are then emitted by the microwave antenna 61 to heat the object to be cooked 200.

[0047] The controller 70 is used to control the cooking process. After the user sets the cooking temperature through the control component 14, the controller 70 acquires the temperature detected by the temperature sensor 40 in real time and then determines whether the temperature detected by the temperature sensor 40 has reached the cooking temperature. If the temperature detected by the temperature sensor 40 reaches the preset temperature (i.e., the cooking temperature set by the user), the controller controls the heater 60 to stop heating. If the temperature detected by the temperature sensor 40 is lower than the preset temperature (e.g., the preset temperature is equal to the cooking temperature minus 5 degrees), the controller 70 controls the heater 60 to start heating again. This cycle repeats to achieve constant temperature heating. Different ingredients require different cooking times. Therefore, the user can set the cooking time through the control component 14. When the heating time reaches the preset time (i.e., the cooking time set by the user), the controller controls the heater 60 to stop heating.

[0048] Please see Figure 1 and Figure 8 The detection method of this application is applied to a cooking appliance 100, and the detection method includes the following steps:

[0049] 011: Control the light source 30 to emit indicator light to the preset cooking area S within the cooking space 50;

[0050] 012: Acquire temperature information collected by temperature sensor 40.

[0051] Specifically, during cooking, the user first opens the door 13 of the outer casing 10. At this time, it can be determined that the user wants to place the object to be cooked 200. The controller 70 can control the light source 30 to emit an indicator light towards the preset cooking area S. The user places the object to be cooked 200 according to the indicator light so that the object to be cooked 200 (or at least the central area of ​​the upper surface of the object to be cooked 200) is covered by the indicator light, that is, the surface of the object to be cooked 200 is illuminated by the indicator light. At this time, it means that the temperature sensor 40 can receive all the infrared light from the object to be cooked 200, thereby accurately obtaining the temperature information of the object to be cooked 200, thus facilitating cooking control.

[0052] By acquiring the temperature information of the object to be cooked 200, heating is stopped when the temperature of the object to be cooked 200 reaches the cooking temperature set by the user. Heating is resumed after the temperature of the object to be cooked 200 decreases, thus achieving constant temperature heating. Furthermore, cooking is confirmed to be complete when the heating time reaches the cooking time set by the user, at which point the heater 60 is controlled to stop heating, thus completing the cooking of the object to be cooked 200. Accurate temperature detection helps improve the cooking effect.

[0053] In one embodiment, the object to be cooked 200 is a chicken leg placed on a plate. The user first sets the cooking temperature and cooking time through the control component 14, and the controller 70 can obtain the cooking temperature and cooking time set by the user. After setting the cooking temperature and cooking time, the user opens the door 13 (not shown). At this time, after receiving the information that the door 13 is open, the controller 70 can confirm that the user needs to cook. At this time, it controls the light source 30 to emit an indicator light. The user moves the object to be cooked 200 according to the indicator light until the indicator light covers the chicken leg on the plate, which means that it has been placed properly. At this time, the user closes the door 13. After receiving the information that the door 13 is closed, the controller 70 determines that cooking can begin. At this time, the controller 70 controls the heater 60 to start heating and acquires the temperature detected by the temperature sensor 40 in real time. When the temperature reaches the cooking temperature, the controller controls the heater 60 to stop heating. When the temperature drops to the preset temperature (e.g., cooking temperature minus 5 degrees), the controller 70 controls the heater 60 to start heating again. This cycle repeats, ensuring that the temperature of the object to be cooked 200 is always approximately equal to the cooking temperature, achieving constant temperature cooking. After the heating time reaches the set cooking time, the controller 70 determines that cooking is complete and controls the heater 60 to stop heating, completing the entire cooking process.

[0054] In addition, for safety reasons, the controller 70 keeps the door 13 locked during the cooking process (i.e., before the heating time reaches the cooking time), preventing the user from opening the door 13. Only after cooking is completed will the door 13 unlock, allowing the user to open it and remove the object 200 to be cooked.
