Description

Technical Field

[0001] This application belongs to the field of household appliances, and particularly relates to a heating furnace. Background Art

[0002] An infrared furnace is a cooking appliance that uses far-infrared rays to heat cookware on the surface of the infrared stove, and it heats the cookware through electrothermal radiation.

[0003] In the related art, a human body and cookware induction device is added to the side of the infrared furnace to achieve the induction of cookware and users. However, since the human body and cookware induction device is exposed on the side of the housing of the infrared furnace, the integration of the human body and cookware induction device and the infrared furnace is poor, which is not aesthetically pleasing visually. At the same time, this structure is likely to cause damage to the human body and cookware induction device, affecting the user experience.

[0004] Therefore, it has become an urgent problem to be solved at present to propose an infrared furnace that can protect the human body and cookware induction device, reduce the product volume, and improve the aesthetics of the product. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0006] To solve the above technical problems, an embodiment of the present application provides a heating furnace.

[0007] To achieve the above object, an embodiment of the present application provides a heating furnace, including: a bottom case; a panel installed on the bottom case, enclosing an installation cavity with the bottom case, and a light-transmitting area is provided on the panel; an induction device installed in the installation cavity, the induction device includes a human body induction device and / or a cookware induction device, and the induction light emitted by the induction device can pass through the light-transmitting area.

[0008] According to the heating furnace provided by the present invention, it includes an installation cavity formed by a bottom shell and a panel, and a human body sensing device, or a cookware sensing device, or a combination of the human body sensing device and the cookware sensing device arranged inside the installation cavity. The human body sensing device can detect whether there is a person in a certain area around the heating furnace through a light-transmitting area, and the cookware sensing device can detect whether there is a cookware on the heating furnace through the light-transmitting area. In the related art, such a human body sensing device or cookware sensing device is separately arranged on the side of the housing of the heating furnace. In this case, there are great inconveniences for users during the use of the heating furnace. For example, the setting of the human body sensing device or the cookware sensing device will increase the volume of the heating furnace, which is not convenient for the storage and transportation of the heating furnace, and the sensing device is also prone to collision with other objects, thus making the sensing device easily damaged. At the same time, the sensing device is arranged on the side wall of the outer shell and cannot be integrated with the heating furnace, which looks rather abrupt in terms of visual effect and greatly affects the user experience. In this application, by arranging the sensing device inside the housing, the sensing device can be better integrated with the heating furnace, greatly improving the aesthetics of the product. And this kind of setting can form a protection for the sensing device through the outer shell of the heating furnace, thereby improving the service life of the sensing device.

[0009] In addition, the heating furnace provided by this application may also have the following additional technical features:

[0010] Optionally, the panel includes a first panel and a second panel connected to each other. The second panel protrudes from the first panel in a direction away from the bottom shell. The sensing device is arranged corresponding to the second panel, and a first distance between the sensing device and the bottom wall of the bottom shell is greater than a second distance between the first panel and the bottom wall of the bottom shell. The light-transmitting area is arranged on the second panel.

[0011] In this technical solution, by setting the panel of the heating furnace into the first panel and the second panel that are not in the same plane, it can be understood that the cookware is placed on the first panel to achieve the cooking function, and the sensing device is arranged in the second panel to detect whether the user exists and whether the cookware exists. And the height position of the second panel from the bottom wall is greater than that of the first panel. The sensing device is arranged corresponding to the second panel, and its distance from the bottom wall is farther than that of the first panel from the bottom wall, that is, the sensing device is arranged higher than the first panel. In this way, the light emitted by the sensing device can be prevented from being blocked by foreign objects, improving the detection effect of the sensing device. In addition, for the solution where the sensing device includes a cookware sensing device, such a setting makes the cookware sensing device approximately flush with the cookware. After the cookware is placed on the first panel, the sensing light emitted by the sensing device can be emitted horizontally towards the cookware, and the infrared light reflected by the cookware can also be received by the cookware sensing device from the horizontal direction. In this way, the cookware sensing device can more easily sense the cookware, thereby improving the accuracy of cookware detection.

[0012] Optionally, a heating area is provided on the first panel, a control area is provided on the second panel, and a light-transmitting area is provided at the connection between the first panel and the second panel. The heating area is used to place cookware for heating the cookware, and buttons are provided on the control area for controlling the heating furnace.

[0013] In this technical solution, the control area is provided on the second panel, that is, the second panel includes a control panel, and the heating area is provided on the first panel, that is, the first panel includes a heating panel. The height of the second panel is higher than that of the first panel, that is, the entire control panel is prominently arranged relative to the heating panel, making the heating area and the control area of the heating furnace clearer. At the same time, since an induction device is provided below the second panel, the second panel is set as the control panel. On the one hand, it is convenient for the power supply of the induction device, and on the other hand, the induction device can be set away from the heating area, so as to reduce the influence of the heating device on the induction device.

[0014] Furthermore, the light-transmitting area is provided at the connection between the second panel and the first panel, so that the induction device can send and receive induction light through the light-transmitting area.

[0015] Optionally, the first panel includes a control area and a heating area arranged along a first direction, and the second panel is arranged on one side of the heating area away from the control area along the first direction. The first direction is the front-back direction of the heating furnace.

[0016] In this technical solution, by arranging the control area and the heating area on the same panel and only arranging the induction device on the second panel, the volume of the cavity formed by the second panel and the bottom wall can be set smaller, that is, compared with the plane of the first panel, the protruding area of the second panel can be set smaller, so that the heating furnace looks relatively flat as a whole in appearance and does not seem so obtrusive, improving the aesthetics of the heating furnace. And the second panel is arranged on one side of the heating area away from the control area along the first direction, that is, the second panel is arranged at the rear end, that is, the rear part of the panel of the heating furnace is set as a protruding structure, and this setting makes the transition between the control area and the heating area smooth, so it is more convenient for cleaning the panel.

[0017] Optionally, the first panel and the second panel have the same dimension in a second direction.

[0018] In this technical solution, in the front-back direction of the heating furnace, the first panel and the second panel are arranged in sequence. It can be understood that in this application, a space for storing the induction device is additionally provided at the rear side of the heating area and the control area of the heating furnace for detecting whether there is a cookware on the heating furnace and whether there is a user around. And the first panel and the second panel have the same dimension in the second direction, that is, the rear end of the panel is integrally set as a protruding structure to form the second panel.

[0019] Optionally, the size of the first panel in the second direction is greater than that of the second panel in the second direction, where the first direction is the front-back direction of the heating furnace and the second direction is the left-right direction of the heating furnace.

[0020] In this technical solution, in the height direction of the first panel of the heating furnace, a second panel with a smaller width is provided. It can be understood that in this application, the second panel is arranged above the first panel in the direction opposite to the bottom wall, that is, a cavity is formed between the first panel and the second panel, so that the overall occupied area of the heating furnace can be not increased. At the same time, the cavity surrounded by the second panel is relatively small and does not affect the normal cooking function of the heating furnace.

[0021] Optionally, the entire panel is in a regular shape, and there is a smooth transition between the first panel and the second panel, that is, the second panel itself is part of the first panel, and it only protrudes relative to the first panel to form the second panel.

[0022] Optionally, the heating furnace includes: a heating device, arranged in the installation cavity, for heating the cookware placed on the panel; a processing unit, for controlling the heating power of the heating device according to the sensing result of the sensing device.

[0023] Among them, the processing unit can determine the actual situation according to the sensing result of the sensing device, so as to control the heating power.

[0024] Optionally, the sensing device includes a human body sensing device and a cookware sensing device, and the processing unit is used for: when the cookware sensing device does not detect the cookware and the human body sensing device detects a human body, controlling the heating power of the heating device to remain unchanged; when the cookware sensing device does not detect the cookware and the human body sensing device does not detect a human body, controlling the heating device to turn off; when the cookware sensing device detects the cookware, controlling the heating power of the heating device according to the temperature of the cookware.

[0025] Among them, the processing unit is used to stop heating when the cookware sensing device senses the absence of the cookware and the human body sensing device fails to detect the presence of a human body, that is, when the human body has moved away. The processing unit is used to keep the heating power of the heating furnace when the cookware sensing device senses the absence of the cookware and the human body sensing device detects the presence of a human body, for example, when the user goes to wash the pot. The processing unit is also used to obtain the temperature of the cookware when the cookware sensing device senses the presence of the cookware, and control the heating power according to the temperature of the cookware.

[0026] Optionally, the sensing device further includes: a temperature detection device, arranged in the installation cavity, for detecting the temperature of the cookware.

[0027] In this technical solution, the temperature of the cookware can be detected by a temperature detection device, and the power of the infrared heating plate in the heating furnace can be adjusted according to the temperature of the cookware, so as to adjust the heating temperature of the cookware, avoid continuous high-temperature heating of the cookware by the infrared heating plate, affect the cooking effect of the cooking ingredients, and achieve functions such as dry-burning protection.

[0028] Optionally, the heating furnace further includes: a mounting base, on which at least two of a human body sensing device, a cookware sensing device, and a temperature detection device are mounted.

[0029] In this technical solution, the mounting base is used to integrally mount the human body sensing device, the cookware sensing device, and the temperature detection device, so that the human body sensing device, the cookware sensing device, and the temperature detection device are arranged in an integrated manner, which can improve the convenience of installing the sensing device and reduce the overall volume of the sensing device at the same time.

[0030] Of course, the human body sensing device, the cookware sensing device, and the temperature detection device can also be arranged independently, so as to improve the flexibility of installing the sensing device.

[0031] Optionally, the sensing device includes a cookware sensing device and a human body sensing device, and the human body sensing device and the cookware sensing device are independently arranged.

[0032] In this technical solution, considering that the cookware sensing device is for detecting the cookware, and the human body sensing device is for detecting the surrounding users, the detection objects of the two are different, and the cookware sensing device needs to be arranged corresponding to the cookware. Therefore, in actual setting, the cookware sensing device and the human body sensing device can also be arranged independently, that is, arranged at different positions in the cavity.

[0033] Optionally, the sensing device includes multiple human body sensing devices, and the multiple human body sensing devices are arranged corresponding to at least two sides of the bottom case.

[0034] In this technical solution, since the installation position of the heating furnace is not fixed, by arranging multiple human body sensing devices, the detection of users can be realized from multiple directions of the front, back, left, and right of the heating furnace, so as to improve the accuracy of detecting whether there is a user and avoid misoperations caused by misjudgment of the heating furnace.

[0035] Optionally, the human body sensing device includes one of an ultrasonic sensor, an infrared pyroelectric sensor, a TOF sensor, a millimeter wave radar sensor, and a microwave radar sensor. In actual setting, the human body sensing device can be selected in different forms according to needs.

[0036] Optionally, the cookware sensing device includes one of an infrared pair tube sensor, an ultrasonic distance sensor, and a TOF sensor. In actual setting, the cookware sensing device can be selected in different forms according to needs.

[0037] Among them, for the heating furnace in this application, the control workflow is as follows:

[0038] (1) Obtain the detection information of the cookware induction device;

[0039] (2) Determine whether there is cookware based on the detection information of the cookware induction device; if so, execute step (3), otherwise execute step (4);

[0040] (3) Obtain the detection information of the temperature detection device, adjust the heating power according to the cookware temperature, and end.

[0041] (4) Obtain the detection information of the human body induction device, and determine whether there is a user around; if so, execute step (5), otherwise execute step (6);

[0042] (5) Maintain a certain heating power and end.

[0043] (6) Turn off the infrared disk and end.

[0044] In this technical solution, considering that the temperature of the heating furnace is relatively high during the working process, when the cookware leaves the surface of the heating stove, the continuous heating of the heating disk not only brings a fire hazard but also increases unnecessary power consumption. And the heating process of the heating stove panel is relatively slow. In combination with the presence induction of the user, when a user is detected to be present, it is prevented that the heating furnace shuts down due to the user's brief operations such as washing the pot and lifting the pot, ensuring the user's operation experience. Therefore, in this application, by detecting whether there is cookware on the heating furnace, when it is detected that there is no cookware, the infrared heating disk is not directly turned off, but further determines whether there is a user performing a brief operation on the cookware, which is convenient for the user to continue using the heating furnace. At the same time, when it is detected that there is cookware, the temperature detection device obtains the temperature of the cookware, and adjusts the power of the infrared disk according to the temperature of the cookware to achieve functions such as dry-burning protection.

[0045] Optionally, the heating furnace includes but is not limited to an infrared furnace and an electro-ceramic furnace.

[0046] Additional aspects and advantages of this application will be partially given in the following description, partially become apparent from the following description, or be understood through the practice of this application. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0057] Hereinafter, embodiments of the present application will be described in detail. Examples of the embodiments are shown in the accompanying drawings, where 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 only for explaining the present application and should not be construed as limiting the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts fall within the scope of protection of the present application.

[0058] Hereinafter, a heating furnace according to an embodiment of the present application will be described with reference to the accompanying drawings.

[0059] As Figure 1 shown, an embodiment of the first aspect of the present application provides a heating furnace, including an installation cavity 3 formed by a bottom case 1 and a panel 2, and a human body sensing device 4, or a cookware sensing device 5, or a combination of the human body sensing device 4 and the cookware sensing device 5 provided inside the installation cavity 3.

[0060] Among them, the panel is mounted on the bottom shell 1, and together with the bottom shell 1, an installation cavity 3 is formed. A light-transmitting area 20 is provided on the panel 2. The sensing device is installed in the installation cavity 3. The sensing device includes a human body sensing device 4 and / or a cookware sensing device 5, and the sensing light emitted by the sensing device can pass through the light-transmitting area 20.

[0061] The heating furnace provided by the present invention can specifically be an infrared furnace, an electric ceramic furnace, etc. The heating furnace includes an installation cavity 3 formed by the bottom shell 1 and the panel 2, and a human body sensing device 4, or a cookware sensing device 5, or a combination of the human body sensing device 4 and the cookware sensing device 5 provided inside the installation cavity 3. The human body sensing device 4 can detect whether there is a person in a certain area around the heating furnace through the light-transmitting area 20, and the cookware sensing device 5 can detect whether there is a cookware on the heating furnace through the light-transmitting area 20. In the related art, such a human body sensing device 4 or a cookware sensing device 5 is separately provided on the side of the shell of the heating furnace. In this way, there are great inconveniences for users during the use of the heating furnace. For example, the setting of the human body sensing device 4 or the cookware sensing device 5 will increase the volume of the heating furnace, which is not convenient for the storage and transportation of the heating furnace, and the sensing device is also easily collided with other objects, resulting in the sensing device being easily damaged. At the same time, the sensing device is arranged on the side wall of the outer shell and cannot be integrated with the heating furnace, which looks rather abrupt in terms of visual effect and greatly affects the user experience. In this application, by arranging the sensing device inside the shell, the sensing device can be better integrated with the heating furnace, greatly improving the aesthetics of the product. And this kind of setting can protect the sensing device through the outer shell of the heating furnace, thereby improving the service life of the sensing device.

[0062] Among them, Figures 1 to 3 The arrows in represent the sensing light emitted by the corresponding sensing device and the sensing light reflected by the cookware 100. Among them, in view of the fact that the human body sensing device 4 and the cookware sensing device 5 are arranged inside the shell, therefore, the human body sensing device 4 and the cookware sensing device 5 cannot be seen from outside the shell. In Figures 1 to 3 In order to show the installation positions of the human body sensing device 4 and the cookware sensing device 5, therefore, a perspective treatment is performed on the positions of the human body sensing device 4 and the cookware sensing device 5.

[0063] Among them, when the sensing device includes a human body sensing device 4, the heating furnace further includes a processing unit 8. The processing unit 8 is used to stop heating when the cookware sensing device 5 senses that there is no cookware and the human body sensing device 4 fails to detect the presence of a person. The processing unit 8 is used to maintain the heating power of the heating furnace when the cookware sensing device 5 senses that there is no cookware and the human body sensing device 4 detects the presence of a person.

[0064] Optionally, when the cookware induction device 5 senses the presence of a cookware, the processing unit 8 is configured to obtain the temperature of the cookware and control the heating power according to the temperature of the cookware.

[0065] Optionally, as Figures 1 to 3 shown, the panel 2 includes a first panel 22 and a second panel 24 that are connected to each other. The second panel 24 protrudes from the first panel 22 in a direction away from the bottom case 1. The induction device is disposed corresponding to the second panel 24, and a first distance between the induction device and the bottom wall of the bottom case 1 is greater than a second distance between the first panel 22 and the bottom wall of the bottom case 1. The light-transmitting area 20 is disposed on the second panel 24.

[0066] In this embodiment, by setting the panel 2 of the heating furnace to the first panel 22 and the second panel 24 that are not in the same plane, it can be understood that the cookware is placed on the first panel 22 to achieve the cooking function, and the induction device is disposed in the second panel 24 to detect whether a user is present and whether a cookware is present. The height of the second panel 24 from the bottom wall is greater than the height of the first panel 22 from the bottom wall, and the induction device is disposed corresponding to the second panel 24. Therefore, the induction device is farther from the bottom wall than the first panel 22, that is, the induction device is disposed higher than the first panel 22, so as to avoid the light emitted by the induction device being blocked by external objects and improve the detection effect of the induction device. In addition, for the solution in which the induction device includes a cookware induction device, such a setting enables the cookware induction device 5 to be substantially flush with the cookware. After the cookware is placed on the first panel 22, the induction light emitted by the induction device can be emitted in a horizontal direction toward the cookware, and the infrared light reflected by the cookware can also be received by the cookware induction device 5 from the horizontal direction, so that the cookware induction device 5 can more easily sense the cookware and improve the accuracy of cookware detection.

[0067] Optionally, the light-transmitting area 20 is disposed on a portion of the second panel 24 close to the first panel 22. This facilitates the infrared radiation reflected by the cookware to be received by the cookware induction device through the light-transmitting area.

[0068] Optionally, as Figure 1 shown, a heating area 28 is disposed on the first panel 22, and a control area 26 is disposed on the second panel 24. The light-transmitting area 20 is disposed at the connection between the first panel 22 and the second panel 24. The heating area 28 is used to place a cookware to heat the cookware, and buttons are disposed on the control area 26 to control the heating furnace.

[0069] In this embodiment, as Figure 1As shown, the control area 26 is provided on the second panel 24, that is, the second panel 24 includes a control panel, and the heating area 28 is provided on the first panel 22, that is, the first panel 22 includes a heating panel. The height of the second panel 24 is higher than that of the first panel 22. That is, the entire control panel is prominently provided relative to the heating panel, making the heating area 28 and the control area 26 of the heating furnace clearer in hierarchy. At the same time, since an induction device is provided below the second panel 24, the second panel 24 is set as the control panel. On the one hand, it is convenient for power supply to the induction device, and on the other hand, the induction device can be set away from the heating area 28, so as to reduce the influence of the heating device 9 on the induction device.

[0070] Further, as Figure 1 shown, the light-transmitting area 20 is provided at the connection between the second panel 24 and the first panel 22, so that the induction device can send and receive induction light through the light-transmitting area 20.

[0071] Optionally, the first panel 22 includes a control area 26 and a heating area 28 arranged along the first direction, and the second panel 24 is arranged on the side of the heating area 28 away from the control area 26 along the first direction. The first direction is the front-back direction of the heating furnace.

[0072] In this embodiment, as Figure 2 and Figure 3 shown, by arranging the control area 26 and the heating area 28 on the same panel and only arranging the induction device on the second panel 24, the volume of the cavity formed by the second panel 24 and the bottom wall can be set smaller. That is, compared with the plane of the first panel 22, the protruding area of the second panel 24 can be set smaller, so that the heating furnace looks relatively flat as a whole in appearance and does not appear so obtrusive, improving the aesthetics of the heating furnace. And the second panel 24 is arranged on the side of the heating area 28 away from the control area 26 along the first direction, that is, the second panel 24 is arranged at the rear end. That is, the rear part of the panel 2 of the heating furnace is set as a protruding structure. And this setting makes the transition between the control area 26 and the heating area 28 smooth, thus making it more convenient to clean the panel 2.

[0073] Optionally, as Figure 2 shown, the first panel 22 and the second panel 24 have the same dimension along the second direction.

[0074] In this embodiment, in the front-back direction of the heating furnace, the first panel 22 and the second panel 24 are arranged in sequence. It can be understood that in this application, a space for storing the induction device is additionally provided at the rear side of the heating area 28 and the control area 26 of the heating furnace for detecting whether there is a cookware on the heating furnace and whether there is a user around. And the first panel 22 and the second panel 24 have the same dimension along the second direction. That is, the rear end of the panel is integrally set as a protruding structure to form the second panel 24.

[0075] Optionally, as Figure 3 shown, the size of the first panel 22 in the second direction is greater than that of the second panel 24 in the second direction, and the second direction is the left - right direction of the heating furnace. That is to say, in the height direction of the first panel 22 of the heating furnace, a second panel 24 with a smaller width is provided. It can be understood that in this application, the second panel 24 is arranged above the first panel 22 in the direction opposite to the bottom wall, forming a cavity, so that the overall occupied area of the heating furnace can be not increased. At the same time, the cavity enclosed by the second panel 24 is relatively small and does not affect the normal cooking function of the heating furnace.

[0076] Optionally, the entire panel 2 is in a regular shape, and there is a smooth transition between the first panel 22 and the second panel 24. That is to say, the second panel 24 itself is part of the first panel 22, and it only protrudes relative to the first panel 22 to form the second panel 24.

[0077] Optionally, as Figure 7 shown, the heating furnace includes: a heating device 9, arranged in the installation cavity, for heating the cookware placed on the panel; a processing unit 8, for controlling the heating power of the heating device 9 according to the sensing result of the sensing device.

[0078] Among them, the processing unit 8 is used to stop heating when the cookware sensing device 5 senses that there is no cookware and the human body sensing device 4 does not detect the presence of a human body. The processing unit 8 is used to maintain the heating power of the heating furnace when the cookware sensing device 5 senses that there is no cookware and the human body sensing device 4 detects the presence of a human body. The processing unit 8 is also used to obtain the temperature of the cookware when the cookware sensing device 5 senses the presence of the cookware, and control the heating power according to the temperature of the cookware.

[0079] Optionally, as Figure 4 and Figure 5 shown, the sensing device further includes: a temperature detection device 6, arranged in the installation cavity 3, for detecting the temperature of the cookware.

[0080] In this embodiment, the temperature of the cookware can be detected by the temperature detection device 6, and the power of the infrared heating plate in the heating furnace can be adjusted according to the temperature of the cookware, so as to realize the adjustment of the heating temperature of the cookware, avoid the continuous high - temperature heating of the infrared heating plate on the cookware, affect the cooking effect of the cooking ingredients, and realize functions such as dry - burning protection.

[0081] Optionally, as Figure 4 and Figure 5 shown, the heating furnace further includes: a mounting base 7, on which at least two of the human body sensing device 4, the cookware sensing device 5, and the temperature detection device 6 are mounted.

[0082] In this technical solution, the mounting base 7 is used to integrally mount the human body sensing device 4, the cookware sensing device 5, and the temperature detection device 6, so that the human body sensing device 4, the cookware sensing device 5, and the temperature detection device 6 are arranged in an integrated manner, which can improve the convenience of installing the sensing device and reduce the overall volume of the sensing device at the same time.

[0083] Of course, the human body sensing device 4, the cookware sensing device 5, and the temperature detection device 6 can also be arranged independently, so as to improve the flexibility of installing the sensing device.

[0084] Optionally, the sensing device includes a cookware sensing device 5 and a human body sensing device 4, and the human body sensing device 4 and the cookware sensing device 5 are independently arranged.

[0085] In this embodiment, as Figure 5 shown, considering that the cookware sensing device 5 is for detecting cookware, while the human body sensing device 4 is for detecting surrounding users, the detection objects of the two are different, and the cookware sensing device 5 needs to be arranged corresponding to the cookware. Therefore, in actual setting, the cookware sensing device 5 and the human body sensing device 4 can also be arranged independently, that is, at different positions in the cavity.

[0086] Optionally, the sensing device includes multiple human body sensing devices 4, and the multiple human body sensing devices 4 are arranged corresponding to at least two sides of the bottom case 1.

[0087] In this embodiment, as Figure 3 shown, since the installation position of the heating furnace is not fixed, by arranging multiple human body sensing devices 4, the detection of users can be realized from multiple directions in front of, behind, left and right of the heating furnace, so as to improve the accuracy of detecting whether there is a user and avoid misoperation caused by misjudgment of the heating furnace.

[0088] Optionally, the human body sensing device 4 includes one of an ultrasonic sensor, an infrared pyroelectric sensor, a TOF sensor, a millimeter wave radar sensor, and a microwave radar sensor. In actual setting, the human body sensing device 4 can be selected in different forms according to needs.

[0089] Optionally, the cookware sensing device 5 includes one of an infrared pair tube sensor, an ultrasonic distance sensor, and a TOF sensor. In actual setting, the cookware sensing device 5 can be selected in different forms according to needs.

[0090] As Figure 1 、 Figure 2 and Figure 3As shown in the figure, another embodiment of the present application provides a heating furnace, including: a bottom case 1; a panel 2, installed on the bottom case 1, enclosing an installation cavity 3 with the bottom case 1, and a light-transmitting area 20 is provided on the panel 2; an induction device, installed in the installation cavity 3, and the induction device includes a cookware induction unit and a human body induction device 4. The cookware induction unit includes two parts, a temperature detection device 6 and a cookware induction device 5. The temperature detection device 6 uses the method of infrared temperature measurement to achieve non-contact temperature detection of the cookware, and obtains the temperature of the cookware by measuring the intensity of the infrared radiation signal emitted by the cookware. The cookware induction device 5 uses sensing methods such as short infrared pair tubes, ultrasonic distance sensors or time-of-flight distance sensors, and determines whether there is a cookware according to the reflected signal received by the sensor. The human body induction device 4 is realized by using a human body induction sensor that can sense the presence of a user, such as an ultrasonic sensor, an infrared pyroelectric sensor, a TOF time-of-flight distance sensor, a millimeter wave radar, a microwave radar, etc., to sense whether there is a user in front of the heating furnace. At the same time, the human body induction device 4 can be integrally arranged with the temperature detection device 6 and the cookware induction device 5; it can also be separately and independently arranged to improve the flexibility of the installation of the induction device.

[0091] As Figure 4 shown, the heating furnace includes a temperature detection device 6 for detecting the temperature of the cookware, a cookware induction device 5 for sensing the presence of the cookware, and a human body induction device 4 for sensing the human body. Among them, the temperature detection device 6, the human body induction device 4, and the cookware induction device 5 are arranged on the same mounting base 7, so that the human body induction device 4, the cookware induction device 5, and the temperature detection device 6 are integrally arranged, thereby improving the installation convenience and at the same time reducing the overall volume of the induction device.

[0092] As Figure 5 shown, the cookware induction device 5 and the human body induction device 4 in the induction device are independently arranged. Considering that the cookware induction device 5 is for detecting the cookware, and the human body induction device 4 is for detecting the surrounding users, the detection objects of the two are different, and the cookware induction device 5 needs to be arranged corresponding to the cookware, so that the cookware induction device 5 and the human body induction device 4 are separately and independently arranged, that is, arranged at different positions in the cavity, thereby further improving the detection accuracy.

[0093] Further, as Figure 3 shown, human body induction devices 4 are provided on multiple sides of the heating furnace. In view of the limited sensing range of each human body induction device, therefore, human body induction devices 4 are provided on multiple sides of the heating furnace to expand the human body sensing range of the heating furnace. Among them, Figure 3 in, the sensing range of the human body induction device 4 is shown.

[0094] Next, the heating furnace of the present application will be further introduced by taking an infrared furnace as an example.

[0095] AsFigure 1 As shown, there is a certain height difference between the control panel of the heating furnace and the surface of the heating stove for accommodating the pan induction unit, and there is a transition surface between the control panel and the heating stove panel. The transition surface is made of a light-transmitting material that can transmit infrared radiation, and the integrated pan induction unit and the human body induction device 4 are installed inside it. The pan induction unit can realize the functions of detecting the presence of the pan and measuring the temperature; the human body induction device 4 can realize the perception of the presence of the user and judge whether the user is operating in front of the heating furnace.

[0096] As Figure 2 shown, a protruding structure can be designed at the tail of the heating furnace for installing the pan induction unit to detect the pan; the human body induction device 4 can also be separately installed on the side of the heating furnace to detect the presence of the user.

[0097] As Figure 3 shown, a protruding structure is designed at a local part of the heating furnace to place the pan induction device 5. At the same time, the human induction devices can be arranged on multiple sides of the heating furnace to realize a wider range of detection of the presence of the user.

[0098] As Figure 7 shown, the infrared furnace includes: a pan induction device 5, a human body induction device 4, a temperature detection device 6, a processing unit 8, and a heating device 9. The processing unit 8 obtains information on whether the pan exists and whether the user is close to the infrared furnace through the pan induction device 5 and the human body induction device 4, and controls the start and stop of the infrared disk. The processing unit 8 can also obtain the temperature information of the pan through the temperature detection device 6, control the heating power of the heating device 9, and realize the control functions of the heating process of the infrared disk such as dry-burning protection.

[0099] As Figure 6 shown, another embodiment of the present application provides a control method for an infrared furnace, including the following steps:

[0100] S602: Obtain the information of the pan induction device, the temperature induction device, and the human body induction device;

[0101] S604: Judge whether the pan exists; if so, execute S606, otherwise execute S610;

[0102] S606: Obtain the temperature of the pan;

[0103] S608: Add power according to the pan temperature; end.

[0104] S610: Judge whether the user is away; if so, execute S612, otherwise execute S614;

[0105] S612: Turn off the infrared disk.

[0106] S614: Keep the heating power.

[0107] According to the embodiment of the present application, the control method of the infrared furnace determines whether a cookware exists by measuring the difference of the reflected signals received by the short-infrared pair tubes through the cookware induction device. If the cookware exists, the infrared radiation intensity received by the temperature induction device is measured to obtain the temperature of the cookware, and the power of the infrared disk is adjusted according to the temperature of the cookware to realize functions such as dry-burning protection. If the cookware does not exist, information on whether the user is away from the infrared furnace is obtained through the human body induction device. If the human body induction device detects that the user is away from the infrared furnace, the infrared disk is turned off to ensure safety; otherwise, heating is maintained at the gear set by the user, facilitating the user to continue using the infrared furnace.

[0108] As Figure 1 、 Figure 2 and Figure 3 shown, the infrared furnace of the present application can be provided with protrusions on the operation panel, the tail of the infrared furnace, and the local part of the infrared furnace. A cookware induction module for detecting the existence of the cookware and measuring the temperature is placed in the transition surface between the protrusion and the infrared stove panel. At the same time, multiple human body induction devices for detecting whether the user is away from the infrared furnace can be arranged on the side of the infrared furnace, or can be arranged together with the cookware induction unit.

[0109] The cookware induction device can use sensing methods such as short-infrared pair tubes, ultrasonic distance sensors, or time-of-flight distance sensors to detect the presence or absence of the cookware. Next, taking an infrared (wavelength 940nm) pair tube (one infrared emitting tube and one infrared receiving tube) as an example, the working process of the cookware induction device of the present application is described. The infrared pair tube measures the infrared reflection intensity signal E1, which is input to the processing unit and compared with the cookware presence threshold Y1 to obtain the presence information of the cookware.

[0110] The temperature detection device can use an infrared thermopile sensor for non-contact temperature measurement. The infrared thermopile sensor measures the radiation intensity E2 radiated by the cookware, which is input to the processing unit, and the temperature information of the cookware on the infrared furnace is obtained according to the built-in mapping relationship in the processing unit.

[0111] The human body induction device can use sensing methods such as ultrasonic sensors, pyroelectric infrared sensors, TOF time-of-flight distance sensors, millimeter wave radars, or microwave radars to realize the induction of the user. Next, taking a microwave radar as an example, the working process of the human body induction device of the present application is described. When the microwave sensor senses the presence of a human body, a high level is output to the processing unit to obtain the presence information of the user.

[0112] Optionally, the infrared furnace includes, but is not limited to, an electro-ceramic stove.

[0113] The infrared furnace control method of the present application specifically includes the following steps:

[0114] First step, obtain the information of the cookware induction device, temperature induction device, and human body induction device and input it into the processing unit.

[0115] Second step, the processing unit determines whether there is cookware; if there is cookware, jump to and execute the third step, if there is no cookware, jump to and execute the fourth step.

[0116] Third step, the processing unit obtains the temperature information of the cookware on the infrared furnace from the infrared radiation E2 measured by the infrared thermopile sensor according to the built-in mapping relationship, and controls the heating plate of the infrared furnace according to the temperature information.

[0117] Fourth step, the processing unit determines whether the user exists according to the information of the human body induction device. If the user exists, maintain the heating power of the infrared furnace; otherwise, turn off the heating plate of the infrared furnace after a period of time (such as 20S).

[0118] The above steps are cycled during the operation of the infrared furnace to implement cookware and user detection to achieve power control of the infrared plate, improving the user experience.
