DETAILED DESCRIPTION

[0051] The exemplary embodiments will be described in detail below with reference to the attached drawings. The following description is not intended to limit the scope of the application in any way, but merely to illustrate the concepts of the application by reference to specific embodiments.

[0057] Optionally, referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 , the infrared detection device 120 of the embodiments of the present application comprises an infrared emitter 121 and an infrared receiver 122, wherein the infrared emitter 121 is used for emitting infrared light to the heating area 1112a; the infrared receiver 122 is used for receiving the infrared light reflected back by the heating area 1112a.

At the same time, when the infrared detection device 120 needs to be repaired, the handle can be quickly disassembled to avoid occupying the operation space, which is beneficial to improve the assembly and repair efficiency of the heating stove 100.

[0080] In some possible implementation manners, as shown in Figures 1 to 6 , the control device of the embodiment of the present application comprises: a control panel 160 and a connecting line, wherein the control panel 160 is arranged in the shell assembly 111; and the connecting line is sequentially arranged in the inner cavity of the shell assembly 111 and the mounting seat 123 and connected with the circuit board 124.

[0081] In some embodiments, the control board 160 is electrically connected with the circuit board 124 through a connecting wire to receive the detection signal of the infrared detection device 120, and the control board 160 is also electrically connected with the heating device 112, and the control board 160 controls the operation state of the heating device 112 according to the detection signal. In addition, a control member 150 can be arranged outside the shell assembly 111, which can be a knob, a button, a remote controller or the like, and the control member 150 is electrically connected with the control board 160 or the heating device 112. When the pot exists in the heating area 1112a, the user can control the heating device 112 to be turned on, turned off or adjusted in the working mode through the control member 150. When the pot does not exist in the heating area 1112a, the control member 150 is disabled, and even if the user mistakenly touches the control member 150, the heating device 112 cannot be started, thereby ensuring the safety of the heating stove 100.

[0082] Specifically, when the pot exists in the heating area 1112a, the infrared emitter 121 emits infrared rays of a certain frequency through the modulation circuit to the pot, and at this time, the pot can act as a kind of reflecting surface. The infrared rays reflected by the pot are received by the infrared receiver 122 and output through the demodulation circuit on the circuit board 124. After the signal is processed by the switching circuit, a low-level signal is output, and the control circuit on the control board 160 detects the signal through the single-chip microcomputer pin. In this way, when the pot exists in the heating area 1112a, the detection circuit on the circuit board 124 outputs a low level, and vice versa, outputs a high level. The above level signals are detected by the single-chip microcomputer pin on the control board 160. When the single-chip microcomputer pin detects a low level, it can be judged that the pot exists in the heating area 1112a, and the heating device 112 can normally start heating, and vice versa, the heating device 112 cannot start heating.

[0083] In some realizable ways, referring to Figures 1 to 7 As shown in the figure, the shell assembly 111 of the embodiment of the application comprises a shell body 1111 and a panel 1112. The shell body 1111 defines a heating cavity 1111a with an open top end. The panel 1112 is arranged on the top of the heating cavity 1111a. The heating device 112 is arranged in the heating cavity 1111a. The infrared detection device 120 is fixedly connected with the shell body 1111.

[0084] It can be understood that the heating area 1112a is arranged on the panel 1112, the heating device 112 is arranged in the heating cavity 1111a, when heating starts, the pot is placed on the panel 1112, and the heating device 112 heats below the panel 1112, so that the pot is prevented from directly contacting the heating device 112, the pot is prevented from being damaged due to excessively high temperature, and the safety of the heating stove 100 is improved. The panel 1112 is a heat conduction member, so as to heat the pot. The material of the shell body 1111 is not limited in the embodiment of the application, and can be a heat insulation member, so as to prevent the shell body 1111 from being too hot to scald a user. The infrared detection device 120 is fixed on the shell body 1111, and whether the pot exists above the panel 1112 is detected.

[0085] In addition, in addition to the heating device 112, a heat dissipation device 140, for example, a heat dissipation fan, can be arranged in the shell body 1111. When the heating device 112 operates, the heat dissipation fan is started synchronously to dissipate heat, so that the shell body 1111 is prevented from being overheated, and the normal use of the heating stove 100 is affected.

[0086] It should be noted that, in order to ensure the accuracy of the infrared detection device 120, the included angle between the infrared emitter 121 and the infrared receiver 122 and the panel 1112 can be 0°-30°, for example, the included angle between the infrared emitter 121 and the infrared receiver 122 and the panel 1112 can be 0°, 5°, 10°, 15°, 20°, 25° or 30°, of course, the embodiment of the application does not limit this, and the included angle between the infrared emitter 121 and the infrared receiver 122 and the panel 1112 can be reasonably selected in the above range according to the needs.

[0087] In some possible implementation manners, referring to FIG. 11, Figures 1 to 8 As shown in FIG. 11, the bottom wall of the heating cavity 1111a is provided with a plurality of fixing columns 1111b; the heating device 112 includes a heating disc 1121 and a heating wire 1122 arranged on the heating disc 1121, and a plurality of fixing ears 1123 corresponding to the fixing columns 1111b are arranged on the periphery of the heating disc 1121, and the fixing ears 1123 are fixedly connected with the fixing columns 1111b.

[0088] In the specific implementation, the heating device 112 is fixed in the heating cavity 1111a by the fixing lug 1123 and the fixing column 1111b, so that the heating device 112 is prevented from moving relative to the heating cavity 1111a during the carrying of the heating furnace 100, and the heating device 112 is prevented from being misaligned with the heating area 1112a on the panel 1112, thereby affecting the heating effect of the heating furnace 100. Therefore, the fixing column 1111b is arranged in the heating cavity 1111a, and the fixing lug 1123 is arranged on the heating disc 1121, so as to improve the stability of the heating device 112 and ensure the heating effect of the heating furnace 100. The fixing lug 1123 is a plurality of fixing lugs arranged around the periphery of the heating disc 1121, the number and position of the fixing column 1111b correspond to the number and position of the fixing lug 1123, and the specific number of the fixing lug 1123 and the fixing column 1111b is not limited in the embodiment of the application, and the heating disc 1121 can be stably connected to the heating cavity 1111a. The heating wire 1122 is spirally arranged in the heating disc 1121, so as to ensure uniform heating of the heating area 1112a.

[0089] In some possible implementation manners, referring to FIG. 1, Figures 1 to 5 The fixing lug 1123 of the heating device 112 according to the embodiment of the application is provided with a through hole 1123a matched with the fixing column 1111b, and the heating device 112 further includes a first elastic member 1124 sleeved on the fixing column 1111b, and two ends of the first elastic member 1124 are connected with the fixing lug 1123 and the bottom wall of the heating cavity 1111a respectively.

[0090] Further, the first elastic member 1124 is arranged between the fixing lug 1123 and the bottom wall of the heating cavity 1111a, which can play a role of buffering and shock absorption, can keep the heating disc 1121 in the correct position, and prevent the heating disc 1121 from being damaged by strong impact, thereby improving the service life of the heating furnace 100.

[0091] In some possible implementation manners, referring to FIG. 1, Figures 1 to 5 The heating device 112 according to the embodiment of the application further includes a support ring 1125 and a second elastic member 1126, wherein the support ring 1125 is supported between the heating disc 1121 and the panel 1112, the periphery of the support ring 1125 is provided with a plurality of support portions 1125a corresponding to the fixing lug 1123, the second elastic member 1126 is sleeved on the fixing column 1111b and located on the side of the fixing lug 1123 away from the first elastic member 1124, and two ends of the second elastic member 1126 are connected with the support portion 1125a and the fixing lug 1123 respectively.

[0092] In some embodiments, the support ring 1125 is arranged between the heating disc 1121 and the panel 1112, and serves to support the panel 1112 and strengthen the structural strength, so as to avoid the deformation of the support panel 1112 due to the excessive weight of the pot, and improve the durability of the heating stove 100. The support ring 1125 is provided with a plurality of support portions 1125a on the side, and the fixed column 1111b is sequentially connected with the first elastic member 1124, the perforation 1123a, the second elastic member 1126 and the support portion 1125a, so that the support ring 1125 can transmit the pressure received to the shell body 1111 through the fixed column 1111b, and improve the support strength of the support ring 1125. At the same time, the second elastic member 1126 arranged between the support portion 1125a and the fixed lug 1123 can also serve to buffer and dampen, so as to ensure that the support ring 1125 is kept in the correct position and the heating disc 1121 is protected from damage.

[0093] The following will take Figure 9 as an example to describe a possible working mode of the heating stove 100 provided by the embodiments of the present application. In the embodiments of the present application, when the heating area has a pot, the infrared detection device outputs a low level signal, and when the heating area does not have a pot, the infrared detection device outputs a high level signal. The control circuit of the control device determines whether the heating area has a pot by detecting whether the single-chip microcomputer pin is low level. Specifically, after the heating stove 100 is powered on, the heating device 112 is initialized to enter a first state, and the infrared detection device 120 starts to detect whether the heating area 1112a has a pot. If the control device determines that the pin signal is high level, it proves that there is no pot, and the control device controls the heating device 112 to prohibit heating. If the control device determines that the pin signal is low level, it proves that there is a pot, and the control device unlocks the heating device 112 to heat. At this time, the heating device 112 can start or stop heating at any time according to the needs of the user, and the heating device 112 enters a second state after starting heating. In the second state, if the control device determines that the pin signal is low level, the heating device 112 continues to heat. If the control device determines that the pin signal is high level, it controls the heating device 112 to start heating protection, that is, to stop heating, until the control device determines that the pin signal is low level to continue heating. Therefore, when the heating area 1112a of the heating stove 100 of the embodiments of the present application does not have a pot, the heating device 112 cannot heat at all. Even if the heating device 112 removes the pot during heating, the control device can quickly control the heating device 112 to stop heating, so as to ensure that the heating stove 100 does not start heating when there is no pot, avoid long-time dry heating of the heating stove 100, and improve the safety of the use of the heating stove 100.

[0094] In summary, the heating stove 100 provided by the embodiment of the present application comprises a stove body 110, an infrared detection device 120 and a control device. The stove body 110 comprises a shell assembly 111 and a heating device 112. The heating device 112 is arranged in the shell assembly 111 to heat a pot on the heating area 1112a of the shell assembly 111. The infrared detection device 120 is arranged outside the shell assembly 111. The infrared detection device 120 detects whether the pot exists on the heating area 1112a by emitting or receiving infrared rays to the heating area 1112a. The control device is electrically connected with the infrared detection device 120 and the heating device 112. The control device controls the operating state of the heating device 112 according to the detection result of the infrared detection device 120. When the pot exists on the heating area 1112a, the heating device 112 is in an unlocked state, and the heating device 112 can be turned on or turned off by the control member 150 on the shell assembly 111. When the pot does not exist on the heating area 1112a, the heating device 112 enters a locked state and cannot start heating. In this way, the heating device 112 can only start heating when the pot exists on the heating area 1112a, so that the heating stove 100 can be prevented from being dry-burned for a long time without the pot, and the safety of the heating stove 100 in use can be improved.
