DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 This is an embodiment of the utility model, which discloses a heating dining stove that prevents dry burning. Specifically, the heating dining stove comprises a stove body 1 with a stove cover 2, a water tray 3 and a built-in heating plate 12 are placed in the stove body 1. In this embodiment, the heating plate can be set as an electric heating plate, and its specific structure and installation method have been disclosed in the prior art, which will not be described in detail here;

[0023] Among them, an installation opening 11 is opened on the front side of the furnace body 1, and a control unit 4 is placed in the installation opening 11. The control unit 4 is connected to the furnace body 1 through an adjustable component 5. A detection component 6 is also fixed at the back end of the furnace body 1. The detection component 6 is used to detect the position of the water tray 3. The detection component 6 and the heating plate 12 are both electrically connected to the control unit 4.

[0024] Secondly, technicians in the relevant field know that in this embodiment, a temperature sensor for detecting the temperature of the water tray 3 can also be installed inside the furnace body 1. The temperature sensor is also electrically connected to the control unit 4 to realize temperature detection. In addition, the control unit 4 described in this embodiment includes a display panel, control buttons and a controller. The specific settings can refer to the existing technology and will not be elaborated here.

[0025] In some embodiments, a recessed portion 41 is provided at the back end of the control unit 4 in the utility model, the detection component 6 is built into the recessed portion 41, and a cover plate 42 is located in front of the recessed portion 41, and an avoidance hole 43 is provided on the end surface of the cover plate 42 for avoiding the detection path of the detection component 6.

[0026] That is, in this embodiment, the detection component 6 is installed on the back end of the control unit 4 to realize the position detection of the water tray 3. The integrated structure allows the detection component 6 to be installed together with the control unit 4, and the installation is simple and convenient. At the same time, the cover plate 42 can provide certain protection for the detection component 6 and improve the overall aesthetics.

[0027] On the basis of the above-mentioned embodiment, the detection component 6 in the utility model is an infrared detection head, and there are two infrared detection heads, one of which is used to detect whether the water tray 3 is lifted up and taken out, and the other infrared detection head is used to detect whether the water tray 3 is lowered and installed on the furnace body 1.

[0028] Furthermore, in the present embodiment, a plurality of step columns 44 are provided in the recessed portion 41, and a through hole is provided on the end surface of the cover plate 42 for the step columns 44 to pass through. The step columns 44 are designed to position the stoppers after the cover plate 42 is plugged in, so as to ensure that the cover plate 42 is positioned by the step edge stops of the step columns 44 when inserted, wherein a threaded hole is provided at the end of the step column 44, and a fastener for fastening the cover plate 42 is connected to the threaded hole, wherein the fastener is configured as a bolt, which is threadedly connected to the end of the step column 44 by the bolt, and the cover plate 42 is fixed by means of the clamping force of the end of the bolt.

[0029] In some embodiments, in the utility model, side wings 45 are fixed on both sides of the control unit 4, and mounting slots 46 are provided on the end faces of the side wings 45. Preferably, in this embodiment, two mounting slots 46 are provided on the end faces of each of the side wings 45. The purpose of adopting the slot structure design is to eliminate the error of the installation position during installation, so as to avoid the problem that the control unit 4 is difficult to install due to the error in the upper and lower positions of the opening 11.

[0030] On the basis of the above-mentioned embodiment, the adjustable component 5 in the utility model includes a plurality of fixing seats 51 fixed on the inner side of the furnace body 1, and preferably, the fixing seats 51 are distributed in a matrix with four, wherein an adjusting rod 52 is threadedly connected to the end face of the fixing seat 51, and a stop portion 53 is provided on the outer side of the adjusting rod 52, and the stop portion 53 abuts against the side wing 45, and a bolt member 54 threadedly connected to the adjusting rod 52 is placed in the mounting slot 46.

[0031] That is to say, in this embodiment, after the bolt member 54 is threadedly connected to the end of the adjusting rod 52, the connection and fixation of the side wings 45 can be achieved, and then the control unit 4 can be fixed. Taking into account the errors of the fixing base 51 during welding or the molding of the outer wall of the furnace body 1, in this embodiment, the adjusting rod 52 can be rotated separately so that the stop parts 53 on the four adjusting rods 52 are in the same plane, which can ensure that when the control unit 4 is installed, the side wings 45 on both sides are in the same plane, thereby improving the flatness of the front side of the control unit 4 after installation.

[0032] Of course, considering the convenient adjustment capability of the adjustment rod 52, the cross-section of the middle portion of the adjustment rod 52 along its radial direction in the utility model is a polygonal structure. The polygonal structure design can realize convenient operation of the adjustment rod 52, thereby improving the overall operability.

[0033] In summary, in the utility model, an infrared detection head is fixed on the rear side of the current control unit 4. When the water tray 3 is put in, the infrared detection head detects the water tray 3 and starts heating. When the water tray 3 is taken out, the infrared detection head detects that the water tray 3 is taken out, and the control unit 4 stops the heating operation of the heating plate, thereby avoiding dry burning of the furnace body 1 to ensure the operating stability of the entire furnace body 1. Secondly, the infrared detection head is designed to be integrated with the control unit 4, which is convenient for line connection. At the same time, the installation of the infrared detection head can be simultaneously completed by installing the control unit 4 during installation, thereby effectively improving the installation efficiency.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
