DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] A heating stove is a temperature control device commonly used by people in cold weather. In a heating stove using electric heating, the electric heating element of the heating stove is usually directly fixed on the shell of the heating stove, and the shell is provided with a through hole for inserting the electric heating element. However, when the heating stove has multiple electric heating elements, multiple through holes need to be opened on the shell, which may lead to insufficient structural strength of the shell of the heating stove.

[0036] Based on the above technical problems, the present application provides an electric heating component, a heating stove and a temperature control device to solve the problem that when the heating stove has multiple electric heating elements, multiple through holes need to be opened on the shell, which may lead to insufficient structural strength of the shell of the heating stove.

[0037] In a first aspect, the present application provides an electric heating component, such as Figure 1 and Figure 2As shown, the electric heating assembly 300 can be applied to the heating stove 10 (such as Fig. 9 ), the electric heating component 300 can convert electrical energy into thermal energy in a conductive state, and the electric heating component 300 includes an electric heating element 310, a first mounting component 320, a second mounting component 330 and a support rod 340.

[0038] The first mounting assembly 320 is used to be mounted on the housing 100 (eg Fig. 9 ) connection; the second mounting assembly 330 is arranged opposite to the first mounting assembly 320 and is arranged at intervals along the first direction XX, and the second mounting assembly 330 is used to connect to the shell 100; the electric heating element 310 and the support rod 340 are both located between the first mounting assembly 320 and the second mounting assembly 330, the first end of the support rod 340 is connected to the first mounting assembly 320, the second end of the support rod 340 is connected to the second mounting assembly 330, and the electric heating element 310 is arranged on the support rod 340 and connected to the support rod 340.

[0039] It can be understood that the electric heating element 310 is a device in the electric heating component 300 for generating heat by powering on. The electric heating element 310 can be a heating resistance wire. The number of electric heating elements 310 can be 1, 2 or more. The number of support rods 340 can be 1, 2 or more. Generally speaking, the more electric heating elements 310 there are, the more support rods 340 are required. The number of support rods 340 can be selected according to actual needs.

[0040] When the electric heating component 300 is applied to the heating stove 10, the electric heating element 310 is supported by the support rod 340. If the support rod 340 is directly connected to the shell 100, the shell 100 needs to be provided with through holes matching the number of the support rods 340 to install the support rods 340. For example, when 6 support rods 340 are provided, at least 6 through holes need to be provided on the shell 100 to install the 6 support rods 340. In the embodiment of the present application, the two ends of the support rod 340 are respectively connected to the shell 100 through the first mounting component 320 and the second mounting component 330. There are multiple electric heating elements 310 and support rods 340, and multiple support rods 340 are required for support. Only a small number of through holes (for example, only 2 or 3 through holes) need to be set on the shell 100 to install the first mounting component 320 and the second mounting component 330. Therefore, when there are a large number of electric heating elements 310, it is possible to avoid opening a large number of through holes on the shell 100, which may lead to insufficient structural strength of the shell 100. In addition, the electric heating element 310 does not need to be in direct contact with the shell 100, which can prevent the electric heating element 310 from short-circuiting with the shell 100 and causing electric shock to the user.

[0041] Specifically, the support rod 340 may be an insulating support rod 340 , so as to prevent the electric heating element 310 from being short-circuited with the first installation assembly 320 and the second installation assembly 330 through the support rod 340 .

[0042] like Figures 1 to 3 As shown, in some embodiments of the present application, the first mounting assembly 320 includes a first mounting member 321 and a bearing member 322. The first mounting member 321 is used to connect with the housing 100. The bearing member 322 is located on a side of the first mounting member 321 close to the electric heating member 310. The bearing member 322 is connected to the first mounting member 321, and the first end of the support rod 340 is placed on the bearing member 322. It can be understood that the bearing member 322 can provide support for the first end of the support rod 340. When the electric heating member 310 needs to be loaded and unloaded, the first mounting member 321 can be left unloaded, and only the bearing member 322 can be removed. Compared with the loading and unloading of the first mounting assembly 320 as a whole, the first mounting member 321 is smaller in size and more convenient to load and unload, thereby making the loading and unloading of the electric heating member 310 more convenient.

[0043] It should also be noted that Fig. 9 Taking the perspective shown as an example, if the supporting member 322 is set horizontally when the electric heating component 300 is in use, only the first end of the support rod 340 can be supported on the supporting member 322. When placing the support rod 340, the first end of the support rod 340 can be placed directly on the supporting member 322, and the second end of the support rod 340 can be fixed to the second mounting component 330 to achieve the fixation of the support rod 340; of course, the first end of the support rod 340 can also be connected to the supporting member 322 by means of a snap connection, a bolt connection or a plug-in connection.

[0044] Specifically, Figure 2 and Figure 3 As shown, the first mounting member 321 includes a first side plate 321a, a second side plate 321b and a third side plate 321c; the first side plate 321a is used to connect to the shell 100, the second side plate 321b is arranged opposite to the first side plate 321a, and the second side plate 321b and the first side plate 321a are arranged at intervals along the second direction YY, the second direction YY is perpendicular to the first direction XX, and the second side plate 321b is used to connect to the shell 100; the third side plate 321c is located between the first side plate 321a and the second side plate 321b, and is located on the side of the first side plate 321a and the second side plate 321b close to the electric heating element 310, the first side plate 321a, the third side plate 321c and the second side plate 321b are connected in sequence to define a avoidance cavity 321d, and the supporting member 322 is located on the side of the third side plate 321c close to the electric heating element 310, and is detachably connected to the third side plate 321c.

[0045] It can be understood that the third side plate 321c is used to provide a support and installation space for the carrier 322, the first side plate 321a and the second side plate 321b are used to support the third side plate 321c, and the first side plate 321a, the second side plate 321b and the third side plate 321c together form a frame structure roughly in the shape of a "C", which has a relatively stable structure and sufficient structural strength. It can provide sufficient support strength for the electric heating element 310. And compared with a solid block structure, the frame structure has a small weight and less material consumption, which can reduce the weight and production cost of the first mounting member 321. On the basis of the relatively light weight of the first mounting member 321, the connection and fixing points between the first mounting member 321 and the housing 100 can be reduced, so that the number of through holes for installing the first mounting member 321 that need to be opened on the housing 100 can be reduced. Among them, the first side plate 321a, the second side plate 321b and the third side plate 321c can be integrally formed, or they can be formed separately and then spliced by means of welding, gluing, snap connection or screw connection, etc.

[0046] In one embodiment, a plurality of jacks 321e penetrating through the third side plate 321c and communicating with the avoidance cavity 321d are provided on the third side plate 321c. The whole of the carrier 322 can be in the shape of a "C". Both ends of the carrier 322 pass through the jacks 321e and extend into the avoidance cavity 321d to achieve detachable connection with the third side plate 321c. It can be understood that when installing the carrier 322, the end of the carrier 322 is inserted into the jack 321e from the side of the third side plate 321c away from the first side plate 321a and the second side plate 321b. The carrier 322 can be detachably connected to the third side plate 321c by means of plugging, making the loading and unloading of the carrier 322 more convenient; in addition, the avoidance cavity 321d can provide sufficient avoidance space for the carrier 322, so that the length of the carrier 322 extending out of the jack 321e can be long enough, so that the carrier 322 is not easily separated from the third side plate 321c due to factors such as vibration.

[0047] In one embodiment, the main part of the carrier 322 can extend along the second direction YY, so that one carrier 322 can be used to carry a plurality of support rods 340. In one embodiment, a nut threadedly connected to the carrier 322 can also be sleeved on the end of the carrier 322. The nut is located on the side of the third side plate 321c close to the first side plate 321a and the second side plate 321b, and the nut is used to provide a limit for the carrier 322 to prevent the end of the carrier 322 from being pulled out of the jack 321e during use.

[0048] In one embodiment, the avoidance cavity 321d extends in a direction perpendicular to the first direction XX and the second direction YY to pass through both sides of the first mounting member 321. On the basis of ensuring that the first mounting member 321 has sufficient structural strength, the material and weight of the first mounting member 321 can be further reduced, thereby further reducing the production cost of the first mounting member 321. In addition, the user can also extend into the avoidance cavity 321d from the opening formed by the avoidance cavity 321d passing through both sides of the first mounting member 321, so as to facilitate the loading and unloading of the nuts on the end of the carrier 322.

[0049] In one embodiment, at least one of the first side plate 321a, the second side plate 321b and the third side plate 321c is provided with a first opening 321f, which can further reduce the material and weight of the first mounting member 321, thereby further reducing the production cost of the first mounting member 321.

[0050] In one embodiment, an auxiliary connecting plate 321g is provided at one end of the first side plate 321a and the second side plate 321b away from the third side plate 321c. The auxiliary connecting plate 321g is arranged opposite to the third side plate 321c and is flush with each other. The auxiliary connecting plate 321g can be attached to and connected to the inner wall of the shell 100 to make the connection between the first mounting member 321 and the shell 100 tighter.

[0051] like Figure 2 and Figure 4 As shown, in some embodiments of the present application, the second mounting assembly 330 includes a support plate 331 and a connecting assembly, the support plate 331 is used to connect with the housing 100, the connecting assembly is detachably connected to the support plate 331, and the second end of the support rod 340 is connected to the connecting assembly. It can be understood that the support plate 331 can provide support for the connecting assembly and the second end of the support rod 340. When the electric heating element 310 needs to be loaded and unloaded, the support plate 331 can be left unloaded, and only the connecting assembly can be removed. Compared with the loading and unloading of the second mounting assembly 330 as a whole, the connecting assembly is smaller in size and more convenient to load and unload, thereby making the loading and unloading of the electric heating element 310 more convenient.

[0052] Specifically, the connection assembly includes a first connection member 332 and a second connection member 333. The first connection member 332 is located on a side of the support plate 331 close to the electric heating member 310 and is connected to the support plate 331. The second connection member 333 is detachably connected to the first connection member 332. The second end of the support rod 340 is connected to the first connection member 332. The second connection member 333 is provided with a conductive terminal 350 connected to the electric heating member 310. It can be understood that the conductive terminal 350 is used to electrically connect to the switch assembly of the electric heating member 310 to achieve the connection between the switch assembly and the electric heating member 310. When multiple electric heating members 310 are provided, all the electric heating members 310 are connected to the second connection member 333. When the electric heating members 310 are disassembled, all the electric heating members 310 can be disassembled at one time by disassembling the second connection member 333, so that the disassembly of the electric heating members 310 is more convenient. It should also be noted that the number of second connecting members 333 can be one or more, the number of electric heating members 310 can be selected according to actual needs, and the second connecting member 333 can be detachably connected to the first connecting member 332 by means of snap connection, bolt connection or snap connection.

[0053] like Figure 4 and Figure 5 As shown, in one embodiment, the first connecting member 332 has a first cavity 332a, and a second opening 332b is provided on one side of the first connecting member 332 close to the electric heating member 310, and the second opening 332b is communicated with the first cavity 332a. It can be understood that the first connecting member 332 is a frame structure with a cavity inside and a second opening 332b on one side, which can reduce the material and weight of the first connecting member 332 on the basis of ensuring that the first connecting member 332 has sufficient structural strength, thereby reducing the production cost of the first connecting member 332. In addition, based on the light weight of the first connecting member 332, the supporting strength required by the support plate 331 can be reduced, thereby reducing the connection and fixing points between the support plate 331 and the housing 100, thereby reducing the number of through holes that need to be opened on the housing 100 for installing the support plate 331.

[0054] In one embodiment, the second connecting member 333 closes the second opening 332 b, thereby preventing the heat generated by the electric heating element 310 from diffusing outward through the second opening 332 b and the first cavity 332 a.

[0055] In one embodiment, a third opening 332c is provided on one side of the first connecting member 332 away from the electric heating member 310, and the third opening 332c is communicated with the first cavity 332a. A fourth opening 331a (such as Figure 2 ), the fourth opening 331a is located opposite to the third opening 332c.

[0056] The second connecting member 333 is located in the first cavity 332a, and the second connecting member 333 can enter and exit the first cavity 332a through the third opening 332c, and the second connecting member 333 can pass through the support plate 331 through the fourth opening 331a. It can be understood that when the electric heating element 310 needs to be disassembled, the first end of the electric heating element 310 can be separated from the first mounting assembly 320, and after the second connecting member 333 is separated from the first connecting member 332, the first connecting member 332 is moved away from the first mounting assembly 320, and moved out of the first cavity 332a through the third opening 332c, and then passed through the support plate 331 through the fourth opening 331a, and the first connecting member 332 can be disassembled. When disassembling the first connecting member 332 and the electric heating element 310, it is not necessary to disassemble the second connecting member 333 and the support plate 331, so that the disassembly of the first connecting member 332 and the electric heating element 310 is more convenient.

[0057] like Figure 5 and Figure 6 As shown, in one embodiment, the edge of the third opening 332c is connected with a flange 332d, and the flange 332d is located on the side of the support plate 331 away from the first connecting member 332. The flange 332d can limit the first connecting member 332 to prevent the first connecting member 332 from moving toward the direction close to the first installation assembly 320 and separating from the support plate 331. The flange 332d and the first connecting member 332 can be integrally formed, or the flange 332d and the first connecting member 332 can be separately formed and then spliced ​​by welding, gluing, clamping or screw connection.

[0058] In one embodiment, the connection assembly further includes a third connection member 334, which is located on a side of the support plate 331 away from the first connection member 332, and a portion of the third connection member 334 passes through the fourth opening 331a and the third opening 332c to be inserted into the first cavity 332a to close the fourth opening 331a and the third opening 332c, and the third connection member 334 is engaged with the first connection member 332. It can be understood that the third connection member 334 mounts and fixes the first connection member 332 on the support plate 331 to prevent the first connection member 332 from being separated from the support plate 331, and at the same time, the third connection member 334 can be used to close the third opening 332c and the fourth opening 331a, so as to prevent the heat generated by the electric heating element 310 from diffusing outward through the third opening 332c and the fourth opening 331a.

[0059] In one embodiment, the third connecting members 334 can all be thermal insulation boards, so that the third connecting members 334 can achieve better thermal insulation effects.

[0060] In one embodiment, if Figure 7As shown, a wiring hole 334a is provided at a corner position of the third connecting member 334, and the wiring opening can be used for the conductive wire connecting the switch assembly and the conductive terminal 350 to pass through, so that the connection between the switch assembly and the conductive terminal 350 is more convenient. In one embodiment, the conductive terminal 350 is located on the side of the second connecting member 333 close to the support plate 331, and the second end of the support rod 340 passes through the second opening 332b and is connected to the second connecting member 333, so that the distance between the conductive terminal 350 and the switch assembly is smaller, so that the connection between the switch assembly and the conductive terminal 350 is more convenient, and the second connecting member 333 has a certain heat insulation effect, which can prevent the heat emitted by the electric heating element 310 from causing the conductive terminal 350 to be damaged due to excessive temperature.

[0061] In a second aspect, based on the above-mentioned electric heating assembly 300, the present application also provides a heating stove, such as Figure 8 and Fig. 9 As shown, the heating stove 10 includes a housing 100 and an electric heating assembly 300 as described in any one of the above embodiments.

[0062] Among them, the shell 100 has a accommodating cavity 110, and the shell 100 as a whole can be a rectangular parallelepiped, a cube, a cylinder or other shapes. The present application does not limit the specific shape of the shell 100; the electric heating component 300 is located in the accommodating cavity 110, and the first mounting component 320 and the second mounting component 300 are both connected to the shell 100.

[0063] In some embodiments of the present application, Figures 8 to 10 As shown, the heating stove 10 further includes a partition 210 and a fan 400 .

[0064] Among them, the partition 210 is located in the accommodating cavity 110 and is connected to the shell 100. The partition 210 divides the accommodating cavity 110 into a first cavity 111 and a second cavity 112. The partition 210 is provided with a ventilation hole 211 penetrating the partition 210, and the shell 100 is provided with an air inlet 120 connected to the first cavity 111 and an air outlet 130 connected to the second cavity 112. It can be understood that the peripheral side of the partition 210 can be connected to the inner wall of the accommodating cavity 110, so as to divide the accommodating cavity 110 into two different cavities (the first cavity 111 and the second cavity 112).

[0065] The fan 400 is located in the second cavity 112 and connected to the housing 100. The exhaust port 410 of the fan 400 faces the vent 211. The fan 400 is used to blow air to the electric heating component 300. It can be understood that the air inlet of the fan 400 is located in the second cavity 112. When the fan 400 is started, the fan 400 can blow air into the second cavity 112 through the exhaust port 410. The air flow passes through the air inlet 120, the second cavity 112, the air inlet, the exhaust port 410, the vent 211, the first cavity 111 and the air outlet 130 in sequence, so that the heat emitted by the electric heating component 300 is taken out of the first cavity 111 through the air outlet 130; wherein the fan 400 can be a ventilator, a blower or a compressor.

[0066] It can be understood that in the present application, the heating stove 10 adopts electric heating for heating, which can avoid the generation of a large amount of nitrogen oxides when gas or oil is burned to cause environmental pollution, and the electric heating component 300 is placed in the first cavity 111 with a relatively small volume space. The heat dissipated by the electric heating component 300 is mainly concentrated in the first cavity 111, so that the heat dissipated by the electric heating component 300 is more concentrated. Combined with the blowing effect of the fan 400, the heat dissipated by the electric heating component 300 can be quickly brought out of the first cavity 111, and the heat can be quickly diffused to the surroundings of the heating stove 10. The heat diffusion efficiency is high, which can improve the heating effect; in addition, the fan 400 is located in the second cavity 112, and the partition 210 can prevent the heat generated by the electric heating component 300 from diffusing to the second cavity 112, so that the temperature in the second cavity 112 is relatively low, thereby preventing the fan 400 and other electronic devices in the second cavity 112 from being damaged due to excessive temperature.

[0067] It should also be noted that the electric heating component 300 and the fan 400 can be respectively equipped with separate power supply lines, that is, the electric heating component 300 and the fan 400 can be connected to the power supply through different power supply lines, so that the opening and closing of the electric heating component 300 and the fan 400 can be controlled separately. When heating is not needed but only ventilation is needed, the heating component can be turned off and the fan 400 can be started. At this time, normal temperature air can be discharged from the air outlet 130 to meet the ventilation needs.

[0068] In one embodiment, one end of the fan 400 with the exhaust port 410 is attached to the partition 210, and the exhaust port 410 and the vent 211 at least partially overlap, so that the wind discharged from the exhaust port 410 flows more concentratedly toward the first cavity 111, so that the heat emitted by the electric heating component 300 can be brought out of the first cavity 111 more quickly. In addition, the body of the fan 400 can also be used to seal the vent 211, so as to ensure that the heat dissipated by the electric heating component 300 is mainly concentrated in the first cavity 111. It should also be noted that the vent 211 can be set to cover the exhaust port 410, and the exhaust port 410 can also be set to cover the vent 211.

[0069] In one embodiment, the air outlet 130 and the vent 211 are located opposite to each other, and the electric heating element 310 is located between the air outlet 130 and the vent 211. It is understandable that the airflow discharged from the air outlet 410 enters the first cavity 111 from the vent 211, can flow through the electric heating element 310 along a roughly straight path and be discharged from the air outlet 130, and the airflow from the vent 211 to the air outlet 130 does not need to turn or change direction, so that the flow path of the airflow is shorter, and can be quickly mixed with the heat flow dissipated by the electric heating element 310, so that the heat emitted by the electric heating component 300 can be brought out of the first cavity 111 more quickly.

[0070] Furthermore, the heating outer surface of the electric heating element 310 is exposed in the first cavity 111, and the electric heating element 310 is spaced apart from the housing 100. It is understandable that the heating outer surface of the electric heating element 310 is not covered with an insulating protective layer or other protective shell 100 and other components, and the heating outer surface is directly in contact with the air in the first cavity 111, so that the heat generated by the electric heating element 310 can be dissipated more quickly, and the electric heating element 310 is spaced apart from the housing 100, which can prevent the electric heating element 310 from short-circuiting with the housing 100 and causing electric shock to the user.

[0071] In one embodiment, the electric heating element 310 can be bent and extended to increase the length of the electric heating element 310 within a limited space, thereby increasing the heat dissipation of the electric heating element 310. In one embodiment, there can be one or more electric heating elements 310. When there are multiple electric heating elements 310, the multiple electric heating elements 310 can be arranged in sequence along the arrangement direction of the vent 211 and the air outlet 130 to ensure that the airflow generated by the fan 400 can flow through all the electric heating elements 310.

[0072] Continue to see Figures 8 to 10As shown, in some embodiments of the present application, the support plate 331 is located in the first cavity 111, the support plate 331 is vertically arranged with the partition 210 and connected to the housing 100, the support plate 331 is vertically arranged with the partition 210 and connected to the housing 100, the support plate 331 divides the first cavity 111 into a first chamber 111a and a second chamber 111b, the vent 211 and the air outlet 130 are both connected to the first chamber 111a, and the electric heating element 310 is located in the first chamber 111a. It can be understood that the peripheral side of the support plate 331 can be connected to the inner wall of the accommodating cavity 110, so as to divide the first cavity 111 into two different chambers (the first chamber 111a and the second chamber 111b), and the volume space of the first chamber 111a is smaller than that of the first cavity 111, and the heat dissipated by the electric heating component 300 is mainly concentrated in the first chamber 111a with a smaller volume, so that the heat dissipated by the electric heating component 300 is more concentrated.

[0073] Furthermore, the heating stove 10 further includes a switch assembly (not shown in the figure), which is located in the second chamber 111b, is electrically connected to the electrical connector, and is used to control the opening and closing of the electric heating element 310. It is understandable that the switch assembly may include electronic components such as switches and circuit boards, and the support plate 331 may prevent the heat generated by the electric heating component 300 from diffusing to the second chamber 111b, thereby making the temperature in the second chamber 111b relatively low, thereby preventing the switch assembly and other electronic components in the second chamber 111b from being damaged due to excessive temperature.

[0074] In one embodiment, a heat insulating layer 140 is provided on the inner wall of the first chamber 111a. The heat insulating layer 140 can be made of materials such as asbestos, foam or aerogel felt. The heat insulating layer 140 has a good heat insulating effect and can prevent the heat in the first chamber 111a from diffusing outward, thereby ensuring that the heat generated by the electric heating component 300 is concentrated in the first chamber 111a. Furthermore, the support plate 331 and the partition 210 can both be heat insulation plates to prevent the heat in the first chamber 111a from diffusing outward.

[0075] In one embodiment, the heating stove 10 further includes an electric control component 230, which is electrically connected to the fan 400, and is used to control the operation of the fan 400, and the electric control component 230 is located in the second cavity 112. It should be noted that the electric control component 230 can be a circuit board component, and the electric control component 230 can control the opening and closing of the fan 400. The electric control component 230 is arranged in the second cavity 112, which can prevent the heat generated by the electric heating element 310 from causing the electric control component 230 to be overheated and damaged.

[0076] In one embodiment, the housing 100 is provided with an inspection port 150 communicating with the second cavity 112, and the housing 100 is provided with a cover plate 220 for opening and closing the inspection port 150. It should be noted that maintenance personnel can observe the operation of the fan 400 and the electric control component 230 through the inspection port 150, and perform maintenance on the fan 400 and the electric control component 230 through the inspection port 150. In addition, the cover plate 220 can also be removed, and the inspection port 150 can be used as an additional air supply port. When the fan 400 is started, the air outside the housing 100 can flow into the second cavity 112 through the inspection port 150.

[0077] It should also be noted that, in one embodiment, the housing 100 may be provided with both an air inlet 120 and an inspection port 150, and the inspection port 150 and the air inlet 120 are located on different sides of the housing 100. In another embodiment, only the air inlet 120 may be provided, and the air inlet 120 may be reused as the inspection port 150, that is, the air inlet 120 and the inspection port 150 are the same opening.

[0078] like Figure 8 As shown, in one embodiment, a plurality of positioning cut holes 160 are arranged on the outer surface of the housing 100 and are spaced apart from each other, and the positioning cut holes 160 are opposite to the second cavity 112. It should be noted that the positioning cut holes 160 are preset hole structures arranged on the housing 100. When the user needs more air outlets, the portion between two adjacent positioning cut holes 160 on the housing 100 can be cut to form an air outlet. Furthermore, the plurality of positioning cut holes 160 can be arranged in a ring shape, and the plurality of positioning cut holes 160 can be arranged in a triangular ring shape, a circular ring shape, a square ring shape, etc., so that after the portion between two adjacent positioning cut holes 160 is cut, the area enclosed by the plurality of positioning cut holes 160 will also be separated from other portions of the housing 100, thereby forming an air outlet with a larger caliber.

[0079] In a third aspect, based on the above-mentioned heating stove 10, the present application also provides a temperature control device, such as Fig.11 As shown, the temperature control device includes a refrigerator 50 and a heating stove 10 as in any one of the above embodiments, so that the temperature control device has both heating and cooling functions, so that the temperature control device can be applied to more usage scenarios. The refrigerator 50 can be interconnected with the heating stove 10, and the refrigerator 50 can also be independent of the heating stove 10.

[0080] Specifically, the refrigerator 50 includes a protective shell 500 and a refrigeration assembly 600; the protective shell 500 has a refrigeration cavity 510, and the refrigeration cavity 510 is connected to the first cavity 111 through the air outlet 130. The protective shell 500 is provided with an exhaust port 520 connected to the refrigeration cavity 510; the refrigeration assembly 600 is located in the refrigeration cavity 510 and connected to the protective shell 500. It should be noted that the refrigerator 50 can be an air conditioner with an indoor unit and an outdoor unit. The indoor unit of the refrigerator 50 can be connected to the heating furnace 10, and the outdoor unit of the refrigerator 50 is installed outdoors. The refrigeration assembly 600 can be an air conditioning refrigeration coil; in this embodiment, the opening and closing of the refrigerator 50 can be independent of the opening and closing of the heating furnace 10. When heating is required, the refrigeration assembly 600 of the refrigerator 50 can be turned off, and the electric heating assembly 300 and the fan 400 of the heating furnace 10 can be turned on. At this time, the temperature control device is in the heating mode, and the airflow generated by the fan 400 passes through the first cavity 111 in sequence. , the air outlet 130, the refrigeration cavity 510 and the exhaust port 520 are discharged from the temperature control device, and the exhaust port 520 discharges hot air; when cooling is needed, the refrigeration component 600 and the fan 400 of the refrigerator 50 can be turned on, and the electric heating component 300 of the heating furnace 10 can be turned off. At this time, the temperature control device is in the cooling mode, and the airflow generated by the fan 400 passes through the first cavity 111, the air outlet 130, the refrigeration cavity 510 and the exhaust port 520 in sequence and then discharges the temperature control device, and the exhaust port 520 discharges cold air. One fan 400 can meet the air supply needs of the heating furnace 10 and the refrigerator 50.

[0081] Specifically, the refrigerator 50 is located on the side of the shell 100 where the air outlet 130 is provided to shorten the distance between the refrigeration cavity 510 and the first cavity 111, so that the arrangement of the refrigerator 50 and the heating stove 10 is more compact, and the overall volume of the temperature control device can be reduced.

[0082] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
