Description

Technical Field

[0001] The present application relates to the technical field of heating devices, and in particular to a heating device and a household appliance. Background Art

[0002] In the related art, bathroom heaters include ceramic heating blocks that radiate heat. However, these heaters only have a single heating method, radiant heating, which has a narrow heat radiation range, slow heating speed, and high energy consumption, resulting in low operating efficiency. Summary of the Invention

[0003] This application aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] To this end, a first aspect of the present application provides a heating device.

[0005] A second aspect of the present application provides a household appliance.

[0006] In view of this, the first aspect of the present application provides a heating device, including: a heating element, the heating element having an electrode portion, and the heating element can generate heat when the electrode portion is in an energized state; a first heat dissipation group, the first heat dissipation group including a first heat dissipation element and a first heat conductive element, the first heat conductive element is connected between the heating element and the first heat dissipation element, the first heat conductive element and the heating element enclose a radiation channel, and the first heat dissipation element is provided with a through heat dissipation channel.

[0007] The heating device provided in this application is applied to household appliances. The heating device includes a heating element and a first heat dissipation group. The first heat dissipation group includes a first heat dissipation element and a first heat conducting element.

[0008] The heating element comprises an electrode portion, and a first heat-conducting member and the heating element enclose a radiation channel. When the electrode portion is energized, the heating element generates heat. A portion of the heat generated by the heating element is radiated through the radiation channel to the heating device, thereby rapidly heating the air in the area (e.g., indoors) where the household appliance is located, thereby forming hot air and heating the indoor air. In other words, the heat generated by the heating element can heat the indoor air by heat radiation through the radiation channel.

[0009] In addition, the first heat-conducting member is connected between the heating element and the first heat sink, that is, the first heat-conducting member is located between the heating element and the first heat sink, and the first heat sink is provided with a through heat dissipation channel. Therefore, another part of the heat generated by the heating element can be transferred to the first heat sink under the action of the first heat-conducting member, and the heat at the first heat sink can heat the gas to form hot air. When the gas flows to the heating device, the gas flows through the heat dissipation channel of the first heat sink, and the hot air at the first heat sink can be blown to different locations in the area where the household appliance is located (such as indoors), so as to achieve the effect of uniformly and quickly increasing the indoor temperature.

[0010] That is to say, the household appliance using the heating device of the present application has both the function of radiant heating and the function of wind heating, thus enriching the function of the household appliance and improving the performance of the product.

[0011] At the same time, the first heat-conducting member is connected between the heating element and the first heat sink. This arrangement shortens the distance between the heating element and the first heat-conducting member, allowing a portion of the heat generated by the heating element to be quickly transferred to the first heat sink via the first heat-conducting member, thereby improving heat conduction efficiency and reducing energy loss. Furthermore, this arrangement helps reduce the assembly distance between the heating element and the first heat sink, thereby reducing the overall dimensions of the heating device, thereby reducing the internal space occupied by the heating device in the household appliance and facilitating the rational layout of other components of the household appliance.

[0012] Specifically, the first heat-conducting member is connected between the heating element and the first heat dissipating member. When the heating element is working, the temperature of the heating element rises, and then radiates heat to the outside. At this time, part of the heat generated by the heating element can be radiated out through the radiation channel enclosed by the first heat-conducting member and the heating element. The radiation channel has the function of guiding airflow, so that the heat radiated by the heating element is directed out to realize radiation heating.

[0013] To sum up, the present application reasonably arranges the matching structure of the heating element and the first heat dissipation group, so that the heating device can not only radiate heat through the radiation channel, but also provide heat through the heat dissipation channel. The heating method of the heating device is diverse, and the combination of air heating and radiation heating can also make the heating device have a larger heat radiation range, and the working efficiency of the heating device is higher.

[0014] In addition, the heating device provided in this application may also have the following additional technical features:

[0015] In some embodiments, optionally, the electrode portion includes two electrodes, the heating element further includes a heating portion, the heating portion is connected between the two electrodes, and each electrode protrudes out of the first heat dissipation group.

[0016] In this technical solution, the electrode part includes two electrodes, which play the role of transmitting electrical energy. The electrodes are used to connect to power supply components such as power supplies, thereby transmitting current and driving the heating element to work.

[0017] The heating element includes a heating portion connected between the two electrodes. The heating portion is the actual heating element. When current passes through the heating element, the heating element works and generates heat.

[0018] Each electrode protrudes from the first heat dissipation group, making it easier to use the electrode to connect to the power supply, facilitating the use of the electrode unit and reducing the difficulty of operation for the user. At the same time, since the heating unit is connected between the two electrodes, the heating unit will not block the two electrodes of the electrode unit. In this way, when assembling the heating device, the difficulty of assembling the electrode unit and other control components can be simplified, thereby improving the assembly efficiency of the product. In addition, the two electrodes are located on different sides of the heating unit, which increases the distance between the two electrodes. In this way, the safety requirements of the two electrodes can be guaranteed, and the safety and reliability of the use of the heating device can be guaranteed.

[0019] In some embodiments, optionally, the heating portion includes a heating body and a sleeve, the heating body is connected between the two electrodes, the heating body is passed through the sleeve, and each electrode extends out of an end of the sleeve.

[0020] In this technical solution, the heating part includes a heating body and a sleeve. The heating body is connected between two electrodes, and the two electrodes are respectively connected to the positive and negative poles of the control component.

[0021] The heating element is inserted into the sleeve, and each electrode extends from the end of the sleeve. The electrode is not only connected to the heating element, but also partially exposed outside the sleeve, providing effective and reliable structural support to ensure the electrical connection between the electrode and the control component, thus achieving power access and control of the entire heating device.

[0022] In summary, the heating part in this application includes a heating body and a sleeve, which achieves efficient and safe heating.

[0023] In some embodiments, optionally, the heating body includes any one of the following or a combination thereof: a far-infrared heating sheet, a heating wire, and a heating tube; when the heating body includes a far-infrared heating sheet, the sleeve is a light-transmitting tube.

[0024] In this technical solution, on the one hand, the heating body includes a far-infrared heating sheet, which uses the radiation characteristics of far-infrared rays to heat the object.

[0025] On the other hand, the heating body includes a heating wire, which is made of metal or alloy. When current passes through, due to the existence of resistance, the electrical energy will be converted into thermal energy, causing the heating wire to heat up and generate heat, thereby realizing the heating of the heating body.

[0026] On the other hand, the heating body includes a heating tube, which includes a metal or alloy wire inside. When current passes through, the metal wire generates heat due to resistance. The heating tube has a high heating power and a long service life, thereby ensuring that the heating body has a long service life.

[0027] On the other hand, the heating body is a combination of a far-infrared heating sheet, a heating wire, and a heating tube. For example, the heating body may include a far-infrared heating sheet and a heating wire, a heating tube and a heating wire, an infrared heating sheet and a heating tube, or a far-infrared heating sheet, a heating wire, and a heating tube. The heating body has various heating forms and can be used more comprehensively.

[0028] In this technical solution, when the heating element includes a far-infrared heating element, the sleeve is a light-transmitting tube. A far-infrared heating element is a heating element that generates infrared radiation. When powered, the internal resistance of the far-infrared heating element generates heat, which in turn radiates far-infrared rays. This infrared radiation has a unique thermal effect that can penetrate deep into human tissue, producing a warming effect and promoting blood circulation and metabolism.

[0029] The sleeve is a light-transmitting tube. On the one hand, the light-transmitting tube can protect the infrared heating plate and prevent the far-infrared heating plate from direct contact with the external environment, thereby avoiding damage or contamination. At the same time, the light-transmitting tube allows far-infrared rays to pass through, ensuring that the far-infrared rays generated by the far-infrared heating plate can directly act on the human body and achieve a therapeutic effect.

[0030] The warming effect of far-infrared radiation dilates blood vessels, promoting blood circulation and helping to alleviate conditions such as muscle pain and arthritis. Infrared radiation penetrates deep into human tissue, promoting cell metabolism and regeneration, and accelerating wound healing and tissue repair. The warming effect of far-infrared radiation can relieve muscle fatigue, stiffness, and pain, improving comfort and mobility.

[0031] In some embodiments, optionally, the portion of the electrode located outside the sleeve includes a first connecting segment and a second connecting segment, and the first connecting segment is located between the heating body and the second connecting segment; the heating element also includes two seals, each seal is mounted on the first connecting segment of an electrode, and the seal is used to seal the connection between the electrode and the sleeve; wherein the seal is an insulating seal.

[0032] In this technical solution, the part of the electrode located outside the sleeve includes a first connecting section and a second connecting section. In terms of position, the first connecting section is located between the heating body and the second connecting section. The first connecting section is between the heating body and another part of the electrode. The first connecting section is a specific connecting part that can achieve better control and optimization of the transfer of electrical energy.

[0033] The heating element also includes two seals, each of which is sleeved on the first connecting section of an electrode, that is, the seal is directly wrapped around or sleeved on the first connecting section of the electrode. The seal is used to seal the connection between the electrode and the sleeve. During the operation of the heating element, the sealing of the connection is ensured to avoid any possible leakage or electrical short circuit.

[0034] The seal is an insulating seal, which not only provides a sealing function but also has insulating properties. The seal can prevent current from flowing from one part to another part where no current should flow, that is, it can prevent the user from accidentally touching the seal and being passed current by the first connecting section, thereby avoiding circuit short circuit or electric shock to the user.

[0035] In summary, the setting of the heating element in this application takes into account the needs of heat transfer, electrical connection, and prevention of leakage and short circuit, so that the heating element works efficiently and safely.

[0036] In some embodiments, optionally, the heating portion is a flat structure; along the thickness direction of the heating portion, the first heat dissipation element is located on one side of the heating element.

[0037] In this technical solution, the heating part has a flat structure. Through the above-mentioned structural setting, on the one hand, the generated heat is evenly distributed on the heating part, and the heat can be quickly extracted. On the other hand, the flat structure makes the heating part compact in shape and occupies a small space, which is suitable for arrangement in a limited space, thereby reducing the overall thickness of the heating device and the volume of the heating device, making it easier to use the heating device.

[0038] Along the thickness direction of the heating part, the first heat sink is located on one side of the heating element, and the first heat sink is not arranged next to the larger end of the heating element. The above arrangement further saves space, so that the entire heating device will not take up too much space while maintaining efficient heat dissipation.

[0039] By setting the shape of the heating portion and the position of the first heat sink, the heating device can operate stably in a compact environment and has higher heat dissipation efficiency.

[0040] Specifically, the heating portion is a flat structure, so when the first heat-conducting member is provided, the heat-conducting sheet can be directly adhered to the heating portion by means of a heat-conducting adhesive, thereby reducing the difficulty of installing the component.

[0041] In some embodiments, optionally, in the first heat dissipation group, the number of first heat dissipation elements is two, the first heat conductive element is a U-shaped heat conductive element, the heating element is inserted into the first heat conductive element, and the first heat conductive element is located between the two first heat dissipation elements; wherein the open end of the first heat conductive element and the heating element enclose a radiation channel.

[0042] In this technical solution, the present application sets a first heat dissipation group, specifically, sets the layout and relationship between the first heat dissipation element, the first heat conduction element, and the heating element. In the first heat dissipation group, there are two first heat dissipation elements, and the first heat dissipation group has two heat dissipation units, which can improve the efficiency of heat dissipation.

[0043] The first heat conducting member is a U-shaped heat conducting member. The first heat conducting member is designed to be U-shaped. This shape setting allows heat to be evenly distributed inside the first heat conducting member and can effectively transfer heat from the heating element to the first heat dissipating element.

[0044] At the same time, this structural arrangement can simultaneously guide the heat generated at different positions of the heating element to the two first heat dissipation elements through the first heat-conducting element, thereby ensuring the balance and consistency of heat conduction and helping to reduce energy consumption.

[0045] Specifically, the heat generating element is inserted into the first heat conducting element, and the heat generating element and the first heat conducting element are in direct contact, thereby ensuring that heat can be efficiently transferred from the heat generating element to the first heat conducting element.

[0046] The first heat conducting member is a U-shaped heat conducting member, and there is a U-shaped clamping groove in the first heat conducting member. When the heating element is inserted into the first heat conducting member, the heating element can be directly clamped into the U-shaped clamping groove. The heating element and the side of the first heat conducting member are tightly fitted and tightly fixed together, and the heat conduction efficiency is higher.

[0047] The first heat-conducting member is located between the two first heat-dissipating members. Heat can be quickly transferred from the first heat-conducting member to the first heat-dissipating members on both sides at one time, which is beneficial to improving the efficiency of heat transfer.

[0048] The open end of the first heat-conducting member and the heating element enclose a radiation channel. The radiation channel allows heat to be radiated into the surrounding environment. The open end allows heat to be dissipated smoothly, ultimately enabling the heating device to provide heat through both air heating and radiation heating, thereby increasing the functionality of the heating device.

[0049] At the same time, a radiation channel is enclosed by the open end of the first heat conductor and the heating element, so the heat radiated by the heating element can only be radiated in the direction of the open end, thereby realizing heat supply to a specific position and improving the heat supply concentration and heating efficiency of the heating device.

[0050] In some embodiments, optionally, there are multiple heating elements and multiple first heat dissipation groups, multiple heating elements are stacked, and each heating element cooperates with one first heat dissipation group.

[0051] In this technical solution, the specific structure of the heating device is defined.

[0052] There are multiple heating elements, multiple first heat dissipation groups, and multiple heating elements are stacked, with each heating element cooperating with one first heat dissipation group.

[0053] It is understood that the heating element and the first heat dissipation group are recorded as a heating unit, and there are multiple heating units, which are stacked. This arrangement can improve the working efficiency of the heating device. Optionally, according to actual usage needs, some of the multiple heating units can be operated, or the multiple heating units can be operated simultaneously.

[0054] In some embodiments, optionally, the first heat conductor is a U-shaped heat conductor, the heating element is inserted into the first heat conductor, and the first heat dissipation element is located on one side of the first heat conductor; the heating element and the first heat dissipation group connected thereto are recorded as a first heating structure, and the number of first heating structures is multiple, and multiple first heating structures are stacked; among the multiple first heating structures, a first heat dissipation element is provided on one side of the outermost first heat conductor.

[0055] In this technical solution, the first heat conductor is a U-shaped heat conductor. The main function of the first heat conductor is to effectively transfer heat. By setting the first heat conductor in a U-shape, it helps to evenly distribute heat in multiple directions.

[0056] The heating element is inserted into the first heat conducting element, which is convenient for installation and allows the heating element to be in close contact with the first heat conducting element. The heating element generates heat which is then smoothly transferred to the first heat conducting element.

[0057] The first heat dissipation member is located on one side of the first heat conduction member, and heat can be transferred from the first heat conduction member to the first heat dissipation member.

[0058] The heating element and the first heat dissipation group connected thereto are referred to as the first heating structure. The heating element is inserted into the first heat conducting element, and the first heat dissipation element is located on one side of the first heat conducting element. Therefore, the heating element and the first heat dissipation group connected thereto constitute a complete heat conduction and heat dissipation structure.

[0059] There are multiple first heating structures, and the multiple first heating structures are stacked. Specifically, the multiple first heating structures are arranged along the direction from the first heat dissipation element to the heating element. This arrangement enables the heating device to include multiple heating elements and multiple first heat dissipation groups, which can improve the efficiency of heat conduction.

[0060] It is understandable that the number of heating elements, first heat sinks and first heat conductors are all multiple. The number of first heat sinks is greater than the number of heating elements, and the number of first heat sinks is greater than the number of first heat conductors. M first heat sinks out of N first heat sinks and multiple heating elements and multiple first heat conductors constitute multiple first heating structures, where N is greater than M. NM first heat sinks are located at the outermost first heat conductor in the first heating structure. This arrangement can further improve the heat dissipation efficiency of the entire heating device, so that more heat is transferred to the heat dissipation channel. When the airflow enters the heat dissipation channel, a large amount of heat is carried out with the airflow to achieve a wind-warming effect.

[0061] In some embodiments, optionally, there are two first heat dissipation groups, and the heating element is connected between the first heat-conducting elements of the two first heat dissipation groups.

[0062] In this technical solution, the number of first heat dissipation groups is specifically two, and the heating element is connected between the first heat-conducting elements of the two first heat dissipation groups. The heat generated by the heating element can be absorbed by the first heat-conducting elements of the two first heat dissipation groups at the same time and dissipated through the first heat dissipation elements respectively connected to them.

[0063] Since the heating element is connected between the two first heat-conducting elements, heat can be distributed more evenly to the two first heat-conducting elements, thereby improving the efficiency of heat transfer.

[0064] In some embodiments, optionally, there are multiple first heat dissipation groups and multiple heating elements, and the multiple heating elements are stacked, and two first heat dissipation groups are arranged between any two adjacent heating elements.

[0065] In this technical solution, the specific structure of the heating device is defined.

[0066] Among them, there are multiple heating elements, multiple first heat dissipation groups, multiple heating elements are stacked, two first heat dissipation groups are set between any two adjacent heating elements, and each heating element cooperates with two first heat dissipation groups.

[0067] It is understood that the heating element and the two first heat dissipation groups are recorded as a heating unit, and there are multiple heating units, and multiple heating units are stacked. This arrangement can improve the working efficiency of the heating device. Optionally, according to actual use needs, some of the multiple heating units can be operated, or the multiple heating units can be operated simultaneously.

[0068] In some embodiments, optionally, the heating element and the first heat dissipation group are recorded as second heating structures, the number of second heating structures is multiple, and multiple second heating structures are stacked; in any two adjacent second heating structures, the heating element of one second heating structure and the first heat dissipation group of another second heating structure are connected through a first heat conductive element; in multiple second heating structures, a first heat dissipation group is provided on one side of the outermost heating element.

[0069] In this technical solution, the heating element and the first heat dissipation group together constitute a second heating structure. There are multiple second heating structures, and the multiple second heating structures are stacked. Specifically, the multiple second heating structures are stacked along the direction from the first heat dissipation element to the heating element. In any two adjacent second heating structures, the heating element of one second heating structure and the first heat dissipation group of the other second heating structure are connected by a first heat conductive member. In addition, in the multiple second heating structures, the first heat dissipation group is provided on one side of the outermost heating element.

[0070] Among them, in any two adjacent second heating structures, the heating element of one second heating structure is connected to the first heat dissipation group of the other second heating structure through a first heat conductive member. This arrangement enables the two adjacent second heating structures to form a continuous heat transfer path, allowing heat to flow between the two adjacent second heating structures, further improving the heat transfer efficiency. This continuous heat transfer path facilitates uniform heat distribution and rapid heat dissipation, thereby improving the heating efficiency of the heating device.

[0071] Furthermore, in the plurality of second heating structures, a first heat dissipation group is provided on one side of the outermost heating element. The first heat dissipation group is responsible for processing the heat generated by the outermost heating element and ensuring that this heat can also be effectively dissipated.

[0072] The heat generated by the outermost heating element can be dissipated through the first heat dissipation group.

[0073] It is understandable that the number of the heating elements, first heat dissipating elements and first heat conducting elements are all multiple. The number of first heat dissipating elements is greater than the number of heating elements, the number of first heat conducting elements is greater than the number of heating elements, and the number of first heat conducting elements is greater than the number of first heat dissipating elements.

[0074] In some embodiments, optionally, the first heat dissipation member includes: a support plate; a second heat conducting member, wherein the second heat conducting member is connected between the support plate and the first heat conducting member, and the second heat conducting member and the support plate enclose a plurality of heat dissipation channels.

[0075] In this technical solution, the first heat sink includes a support plate and a second heat conductor. The support plate is the basic structural part of the first heat sink. Specifically, the support plate is usually made of a material that is both heat-resistant and has a certain thermal conductivity, such as metal, to provide stable support and basic heat dissipation function.

[0076] The second heat-conducting member is a component connected between the support plate and the first heat-conducting member. The main function of the second heat-conducting member is to effectively transfer heat from the first heat-conducting member to the support plate so as to further dissipate the heat.

[0077] The second heat conducting member and the support plate enclose a plurality of heat dissipation channels. When heat is transferred to the support plate through the second heat conducting member, the heat dissipation channels can guide the heat flow, increase the heat dissipation area, and improve the heat dissipation efficiency so that the heat can be dissipated to the environment more quickly.

[0078] In some embodiments, optionally, the second heat conducting member is a corrugated heat conducting member.

[0079] In this technical solution, the second heat-conducting member is a wavy heat-conducting member, which is composed of a series of undulating corrugations. These corrugations can be regarded as countless small heat-conducting units. Each heat-conducting unit can effectively transfer heat from the high-temperature area to the low-temperature area. Through the continuous corrugated structure, heat can be evenly distributed on the entire second heat-conducting member.

[0080] The wavy heat conducting member has excellent thermal conductivity and heat dissipation effect. The wavy heat conducting member can quickly conduct a large amount of heat in a short period of time, thereby improving the heating efficiency of the heating device.

[0081] In some embodiments, optionally, the second heat conducting member includes: a plurality of fins, the plurality of fins are arranged at intervals, each fin is connected between the support plate and the first heat conducting member, and any two adjacent fins and the support plate enclose a heat dissipation channel.

[0082] In this technical solution, the second heat-conducting member includes a plurality of fins, which are arranged at intervals, thereby not only increasing the heat-conducting area but also forming an effective heat transfer path through the connection between the fins, the support plate and the first heat-conducting member.

[0083] Each fin acts as a heat-conducting bridge, quickly transferring heat from the high-temperature area to the low-temperature area. At the same time, the spacing between the fins allows air to flow freely, thereby taking away the heat from the fins and improving the heat dissipation efficiency.

[0084] Any two adjacent fins and support plates enclose a heat dissipation channel. These heat dissipation channels form a natural convection system, allowing heat to be removed more quickly through air convection.

[0085] In some embodiments, optionally, the number of the first heat dissipation element, the first heat conductive element and the heating element are all multiple; the multiple heating elements are stacked, and a first heat dissipation group, a first heat conductive element and a second heat conductive element are arranged between any two adjacent heating elements, and a first heat dissipation group is arranged on one side of the outermost heating element.

[0086] In this technical solution, the specific structure of the heating device is defined.

[0087] There are multiple heating elements, multiple first heat dissipating elements, and multiple first heat conducting elements. The multiple heating elements are stacked, and a first heat dissipating group, a first heat conducting element, and a second heat conducting element are provided between any two adjacent heating elements, and the first heat dissipating group is provided on one side of the outermost heating element.

[0088] It is understood that the heating element and a first heat dissipation group are referred to as a heating unit. There are multiple heating units, and multiple heating units are stacked. A first heat conducting member and a second heat conducting member are provided between two adjacent heating units. The first heat dissipation group is provided on one side of the outermost heating element.

[0089] This arrangement can improve the working efficiency of the heating device. In addition, while ensuring the working efficiency of the heating device, this arrangement reduces the number of support plates, which is conducive to reducing the production cost of the heating device.

[0090] Optionally, according to actual use requirements, a part of the multiple heating units can be operated, or the multiple heating units can be operated simultaneously.

[0091] According to a second aspect of the present application, the present application proposes a household appliance, which includes a heating device as described in any of the above technical solutions.

[0092] The household appliance provided in the present application includes the heating device as in the first aspect, and therefore has all the beneficial effects of the above-mentioned heating device, which will not be described one by one here.

DETAILED DESCRIPTION

[0109] In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other in the absence of conflict.

[0110] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0111] Refer to the following Figures 1 to 11 To describe a heating device 100 and a household appliance proposed in this application.

[0112] like Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments of the application, a heating device 100 is proposed, including: a heating element 110, the heating element 110 has an electrode portion 120, and the heating element 110 can generate heat when the electrode portion 120 is in an energized state; a first heat dissipation group 130, the first heat dissipation group 130 includes a first heat dissipation element 132 and a first heat conductive element 134, the first heat conductive element 134 is connected between the heating element 110 and the first heat dissipation element 132, the first heat conductive element 134 and the heating element 110 enclose a radiation channel 140, and the first heat dissipation element 132 is provided with a through heat dissipation channel 150.

[0113] In this embodiment, the heating device 100 provided by the present application is applied to a household appliance. The heating device 100 includes a heating element 110 and a first heat dissipation group 130. The first heat dissipation group 130 includes a first heat dissipation element 132 and a first heat conducting element 134.

[0114] The heating element 110 includes an electrode portion 120, and a first heat-conducting member 134 and the heating element 110 enclose a radiation channel 140. When the electrode portion 120 is energized, the heating element 110 generates heat. A portion of the heat generated by the heating element 110 is radiated to the heating device 100 through the radiation channel 140, thereby rapidly heating the air in the area (e.g., indoors) where the household appliance is located, thereby forming hot air and heating the indoor air. In other words, the heat generated by the heating element 110 can heat the indoor air by heat radiation through the radiation channel 140.

[0115] In addition, the first heat-conducting member 134 is connected between the heating element 110 and the first heat sink 132, that is, the first heat-conducting member 134 is located between the heating element 110 and the first heat sink 132, and the first heat sink 132 is provided with a through heat dissipation channel 150. Therefore, another part of the heat generated by the operation of the heating element 110 can be transferred to the first heat sink 132 under the action of the first heat-conducting member 134, and the heat at the first heat sink 132 can heat the gas to form hot air. When the gas flows to the heating device 100, the gas flows through the heat dissipation channel 150 of the first heat sink 132, and the hot air at the first heat sink 132 can be blown to different locations in the area where the household appliance is located (such as indoors), so as to achieve the effect of uniformly and quickly increasing the indoor temperature.

[0116] That is, the household appliance using the heating device 100 of the present application has both the function of radiant heating and the function of wind heating, thereby enriching the functions of the household appliance and improving the performance of the product.

[0117] At the same time, the first heat conducting member 134 is connected between the heating element 110 and the first heat dissipating member 132. This arrangement shortens the distance between the heating element 110 and the first heat conducting member 134, allowing a portion of the heat generated by the heating element 110 to be quickly transferred to the first heat dissipating member 132 via the first heat conducting member 134, thereby improving the efficiency of heat conduction and reducing energy loss. In addition, this arrangement helps to reduce the assembly distance between the heating element 110 and the first heat dissipating group 130, thereby reducing the external dimensions of the heating device 100, thereby reducing the internal space occupied by the heating device 100 in the household appliance and facilitating the rational layout of other components of the household appliance.

[0118] Specifically, the first heat conducting member 134 is connected between the heating element 110 and the first heat dissipating member 132. When the heating element 110 is working, the temperature of the heating element 110 increases, and then radiates heat to the outside. At this time, part of the heat generated by the heating element 110 can be radiated out through the radiation channel 140 enclosed by the first heat conducting member 134 and the heating element 110. The radiation channel 140 has the function of guiding air flow, so that the heat radiated by the heating element 110 is directed out to realize radiation heating.

[0119] In summary, the present application reasonably arranges the matching structure of the heating element 110 and the first heat dissipation group 130, so that the heating device 100 can generate heat through the radiation channel 140 and also provide heat through the heat dissipation channel 150. The heating method of the heating device 100 is diverse, and the combination of air heating and radiation heating can also make the heating device 100 have a larger heat radiation range, and the working efficiency of the heating device 100 is higher.

[0120] like Figure 1 、 Figure 2 and Figure 10 As shown, in some embodiments, optionally, the electrode portion 120 includes two electrodes 122 , the heating element 110 further includes a heating portion 112 , the heating portion 112 is connected between the two electrodes 122 , and each electrode 122 protrudes out of the first heat dissipation group 130 .

[0121] In this embodiment, the electrode portion 120 includes two electrodes 122 , which serve to transfer electrical energy. The electrodes 122 are used to connect to power supply components such as a power source, thereby transferring current and driving the heating element 110 to work.

[0122] The heating element 110 includes a heating portion 112, which is connected between two electrodes 122. The heating portion 112 is an actual heating element. When current passes through the heating element, the heating element 110 operates to generate heat.

[0123] Each electrode 122 protrudes from the first heat dissipation group 130, making it easier to use the electrode 122 to connect to the power supply, making it easier to use the electrode part 120 and reducing the difficulty of operation for the user. At the same time, since the heating part 112 is connected between the two electrodes 122, the heating part 112 will not block the two electrodes 122 of the electrode part 120. In this way, when assembling the heating device 100, the difficulty of assembling the electrode part 120 and other control components can be simplified, thereby improving the assembly efficiency of the product. In addition, the two electrodes 122 are located on different sides of the heating part 112, which increases the distance between the two electrodes 122. In this way, the safety requirements of the two electrodes 122 can be guaranteed, and the safety and reliability of the use of the heating device 100 can be guaranteed.

[0124] Specifically, one of the two electrodes 122 has a positive polarity, and the other of the two electrodes 122 has a negative polarity. The positive electrode 122 of the two electrodes 122 is connected to the positive electrode of the control component, and the negative electrode 122 of the two electrodes 122 is connected to the negative electrode of the control component, thereby forming a complete path for current flow.

[0125] Specifically, the electrode 122 includes a metal electrode, a carbon material electrode, an oxide electrode, a composite material electrode, and an organic material electrode.

[0126] Specifically, in this application, the heating portion 112 is ceramic.

[0127] like Figure 2 As shown, in some embodiments, optionally, the heating portion 112 includes a heating body 114 and a sleeve 116 , the heating body 114 is connected between two electrodes 122 , the heating body 114 is passed through the sleeve 116 , and each electrode 122 extends out of the end of the sleeve 116 .

[0128] In this embodiment, the heating portion 112 includes a heating body 114 and a sleeve 116 . The heating body 114 is connected between two electrodes 122 . The two electrodes 122 are respectively connected to the positive and negative poles of the control component.

[0129] Specifically, the heating body 114 is directly connected between the two electrodes 122 to form a current path.

[0130] The heating element 114 is inserted into a sleeve 116 (optionally, the sleeve 116 is an insulating member). The sleeve 116 is used to protect the heating element 114 from direct contact with the surrounding environment while ensuring that the current can pass safely. The heating element 114 is located within the sleeve 116 to ensure that the current passing through the heating element 114 will not cause harm to people.

[0131] Specifically, sleeve 116 is made of a high-temperature-resistant, insulating material, such as ceramic or specialty plastic. Sleeve 116 provides a certain degree of mechanical strength, protecting the heating element from external physical impact and damage. Furthermore, the internal space of sleeve 116 provides a path for heat dissipation from heating element 114, thereby improving the operating stability of heating element 114 and maintaining a stable operating state.

[0132] The heating element 114 is inserted into the sleeve 116, and each electrode 122 extends from the end of the sleeve 116. The electrodes 122 are not only connected to the heating element 114, but are also partially exposed outside the sleeve 116, providing effective and reliable structural support to ensure the electrical connection between the electrode portion 120 and the control component, thereby achieving power access and control of the entire heating device 100.

[0133] In summary, the heating portion 112 in the present application includes a heating body 114 and a sleeve 116 , achieving efficient and safe heating.

[0134] In some embodiments, optionally, the heating body 114 includes any one of the following or a combination thereof: a far-infrared heating sheet, a heating wire, and a heating tube; when the heating body 114 includes a far-infrared heating sheet, the sleeve 116 is a light-transmitting tube.

[0135] In this embodiment, on one hand, the heating body 114 includes a far-infrared heating sheet, which heats an object by utilizing the radiation characteristics of far-infrared rays.

[0136] On the other hand, the heating body 114 includes a heating wire, which is made of metal or alloy. When current passes through, due to the existence of resistance, the electrical energy will be converted into thermal energy, causing the heating wire to heat up and generate heat, thereby achieving heating of the heating body 114.

[0137] On the other hand, the heating body 114 includes a heating tube, which includes a metal or alloy wire inside. When current passes through, the metal wire generates heat due to resistance. The heating tube has a high heating power and a long service life, thereby ensuring that the heating body 114 has a long service life.

[0138] On the other hand, the heating body 114 is a combination of a far-infrared heating sheet, a heating wire, and a heating tube. For example, the heating body 114 may include a far-infrared heating sheet and a heating wire, or a heating tube and a heating wire, or an infrared heating sheet and a heating tube, or a far-infrared heating sheet, a heating wire, and a heating tube. The heating body 114 has various heating modes and can be used more comprehensively.

[0139] In this embodiment, when the heating element 114 includes a far-infrared heating element, the sleeve 116 is a light-transmitting tube. A far-infrared heating element is a heating element that generates infrared radiation. When powered, the internal resistance of the far-infrared heating element generates heat, which in turn radiates far-infrared radiation. This infrared radiation has a unique thermal effect that can penetrate deep into human tissue, producing a warming effect and promoting blood circulation and metabolism.

[0140] The sleeve 116 is a light-transmitting tube. On the one hand, the light-transmitting tube can protect the infrared heating plate and prevent the far-infrared heating plate from direct contact with the external environment, thereby avoiding damage or contamination. At the same time, the light-transmitting tube allows far-infrared rays to pass through, ensuring that the far-infrared rays generated by the far-infrared heating plate can directly act on the human body and achieve a therapeutic effect.

[0141] The warming effect of far-infrared radiation dilates blood vessels, promoting blood circulation and helping to alleviate conditions such as muscle pain and arthritis. Infrared radiation penetrates deep into human tissue, promoting cell metabolism and regeneration, and accelerating wound healing and tissue repair. The warming effect of far-infrared radiation can relieve muscle fatigue, stiffness, and pain, improving comfort and mobility.

[0142] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, the portion of the electrode 122 located outside the sleeve 116 includes a first connecting segment 124 and a second connecting segment 126, and the first connecting segment 124 is located between the heating body 114 and the second connecting segment 126; the heating element 110 also includes two seals 118, each seal 118 is sleeved on the first connecting segment 124 of an electrode 122, and the seal 118 is used to seal the connection between the electrode 122 and the sleeve 116; wherein the seal 118 is an insulating seal.

[0143] In this embodiment, the portion of the electrode 122 located outside the sleeve 116 includes a first connecting segment 124 and a second connecting segment 126. In terms of position, the first connecting segment 124 is located between the heat generating body 114 and the second connecting segment 126. The first connecting segment 124 is between the heat generating body 114 and another portion of the electrode 122. The first connecting segment 124 is a specific connecting portion that can achieve better control and optimization of the transfer of electrical energy.

[0144] The heating element 110 also includes two seals 118, each seal 118 is sleeved on the first connecting section 124 of an electrode 122, that is, the seal 118 is directly wrapped or sleeved on the first connecting section 124 of the electrode 122, and the seal 118 is used to seal the connection between the electrode 122 and the sleeve 116. During the operation of the heating element 110, the sealing of the connection is ensured to avoid any possible leakage or electrical short circuit.

[0145] Specifically, the seal 118 is sleeved on the first connecting section 124 of the electrode 122, so that a closed space is formed in the sleeve 116. The sleeve 116 can be filled with inert gas, thereby extending the heating life and heating efficiency of the heating element 110. The seal 118 can prevent the leakage of the inert gas.

[0146] Specifically, the sleeve 116 is a flat quartz glass tube, and the sealing member 118 can be disposed at the connection between the electrode 122 and the sleeve 116 by sintering, thereby further improving the sealing effect.

[0147] The seal 118 is an insulating seal. The seal 118 not only provides a sealing function, but also has an insulating property. The seal 118 can prevent current from flowing from one part to another part where no current should flow. That is, it can prevent the user from accidentally touching the seal 118 and transmitting current to the first connecting section 124, thereby avoiding circuit short circuit or electric shock to the user.

[0148] In summary, the configuration of the heating element 110 in this application takes into account the requirements of heat transfer, electrical connection, and prevention of leakage and short circuit, so that the heating element 110 works efficiently and safely.

[0149] like Figure 3 and Figure 5 As shown, in some embodiments, optionally, the heating portion 112 is a flat structure; along the thickness direction of the heating portion 112 , the first heat dissipation element 132 is located on one side of the heating element 110 .

[0150] In this embodiment, the heating portion 112 is a flat structure. Through the above-mentioned structural setting, on the one hand, the generated heat is evenly distributed on the heating portion 112, and the heat can be quickly extracted. On the other hand, the flat structure makes the heating portion 112 compact in shape and occupies a small space, which is suitable for arrangement in a limited space, thereby reducing the overall thickness of the heating device 100 and the volume of the heating device 100, making it easier to use the heating device 100.

[0151] Along the thickness direction of the heating portion 112, the first heat dissipation element 132 is located on one side of the heating element 110. The first heat dissipation element 132 is not arranged next to the larger end of the heating element 110. The above arrangement further saves space, so that the entire heating device 100 does not take up too much space while maintaining efficient heat dissipation.

[0152] By setting the shape of the heating portion 112 and the position of the first heat dissipation member 132 , the heating device 100 can operate stably in a compact environment and has higher heat dissipation efficiency.

[0153] Specifically, the heating portion 112 is a flat structure. Therefore, when the first heat-conducting member 134 is provided, the heat-conducting sheet can be directly adhered to the heating portion 112 by means of a heat-conducting adhesive, thereby reducing the difficulty of installing the components.

[0154] like Figure 4 and Figure 6 As shown, in some embodiments, optionally, in the first heat dissipation group 130, the number of the first heat dissipation members 132 is two, the first heat conductive member 134 is a U-shaped heat conductive member 135, the heating element 110 is inserted into the first heat conductive member 134, and the first heat conductive member 134 is located between the two first heat dissipation members 132; wherein, the open end 136 of the first heat conductive member 134 and the heating element 110 enclose a radiation channel 140.

[0155] In this embodiment, the present application provides a first heat dissipation group 130, specifically, the layout and relationship between the first heat dissipation element 132, the first heat conduction element 134, and the heating element 110. In the first heat dissipation group 130, there are two first heat dissipation elements 132, and the first heat dissipation group 130 has two heat dissipation units, which can improve the efficiency of heat dissipation.

[0156] The first heat conducting member 134 is a U-shaped heat conducting member 135 . The first heat conducting member 134 is designed to be U-shaped. This shape setting allows heat to be evenly distributed inside the first heat conducting member 134 and can effectively transfer heat from the heating element 110 to the first heat dissipating member 132 .

[0157] At the same time, this structural arrangement can simultaneously guide the heat generated at different positions of the heating element 110 to the two first heat dissipating elements 132 through the first heat conducting element 134, thereby ensuring the balance and consistency of heat conduction and helping to reduce energy consumption.

[0158] Specifically, the heating element 110 is inserted into the first heat conducting element 134 , and the heating element 110 and the first heat conducting element 134 are in direct contact, thereby ensuring that heat can be efficiently transferred from the heating element 110 to the first heat conducting element 134 .

[0159] The first heat conducting member 134 is a U-shaped heat conducting member 135. There is a U-shaped snap-in groove in the first heat conducting member 134. When the heating element 110 is inserted into the first heat conducting member 134, the heating element 110 can be directly snapped into the U-shaped snap-in groove. The heating element 110 fits tightly with the side of the first heat conducting member 134 and is tightly fixed together, which makes the heat conduction more efficient.

[0160] The first heat conducting member 134 is located between the two first heat dissipating members 132 . Heat can be quickly transferred from the first heat conducting member 134 to the first heat dissipating members 132 on both sides at one time, which is beneficial to improving the efficiency of heat transfer.

[0161] The open end 136 of the first heat conducting member 134 and the heating element 110 enclose a radiation channel 140. The radiation channel 140 allows heat to be radiated into the surrounding environment, and the open end 136 allows the heat to be dissipated smoothly, ultimately enabling the heating device 100 to provide heat through both air heating and radiation heating, thereby increasing the functionality of the heating device 100.

[0162] At the same time, a radiation channel 140 is enclosed by the open end 136 of the first heat conducting member 134 and the heating member 110, so that the heat radiated by the heating member 110 can only be radiated in the direction of the open end 136, thereby achieving heat supply to a specific position, thereby improving the heat supply concentration and heating efficiency of the heating device 100.

[0163] like Figure 7 As shown, in some embodiments, optionally, the first heat conductor 134 is a U-shaped heat conductor 135, the heating element 110 is inserted into the first heat conductor 134, and the first heat dissipation element 132 is located on one side of the first heat conductor 134; the heating element 110 and the first heat dissipation group 130 connected thereto are recorded as a first heating structure 160, and the number of first heating structures 160 is multiple, and multiple first heating structures 160 are stacked; among the multiple first heating structures 160, the first heat dissipation element 132 is provided on one side of the outermost first heat conductor 134.

[0164] In this technical solution, the first heat conductor 134 is a U-shaped heat conductor 135. The main function of the first heat conductor 134 is to effectively transfer heat. By setting the first heat conductor 134 in a U shape, it helps to evenly distribute heat in multiple directions.

[0165] The heating element 110 is inserted into the first heat conducting element 134 , which facilitates installation of the heating element 110 and allows the heating element 110 to be in close contact with the first heat conducting element 134 . The heating element 110 generates heat, which can then be smoothly transferred to the first heat conducting element 134 .

[0166] The first heat dissipation member 132 is located on one side of the first heat conducting member 134 , and heat can be transferred from the first heat conducting member 134 to the first heat dissipation member 132 .

[0167] The heating element 110 and the first heat dissipation group 130 connected thereto are recorded as the first heating structure 160. The heating element 110 is inserted into the first heat conducting element 134, and the first heat dissipation element 132 is located on one side of the first heat conducting element 134. Therefore, the heating element 110 and the first heat dissipation group 130 connected thereto constitute a complete heat conduction and heat dissipation structure.

[0168] There are multiple first heating structures 160, and the multiple first heating structures 160 are stacked. Specifically, the multiple first heating structures 160 are arranged along the direction from the first heat dissipation element 132 to the heating element 110. This arrangement enables the heating device 100 to include multiple heating elements 110 and multiple first heat dissipation groups 130, which can improve the efficiency of heat conduction.

[0169] It is understood that there are multiple heating elements 110, first heat sinks 132, and first heat conductors 134. The number of first heat sinks 132 is greater than the number of heating elements 110, and the number of first heat sinks 132 is greater than the number of first heat conductors 134. M of the N first heat sinks 132, together with the multiple heating elements 110 and the multiple first heat conductors 134, form multiple first heating structures 160, where N is greater than M. The NM first heat sinks 132 are located on the outermost first heat conductors 134 in the first heating structure 160.

[0170] This arrangement can further improve the heat dissipation efficiency of the entire heating device 100 , thereby transferring more heat to the heat dissipation channel 150 . When the airflow enters the heat dissipation channel 150 , a large amount of heat is carried out with the airflow, achieving a wind-warming effect.

[0171] like Figure 1 and Figure 4 As shown, in some embodiments, optionally, there are two first heat dissipation groups 130 , and the heating element 110 is connected between the first heat conducting elements 134 of the two first heat dissipation groups 130 .

[0172] In this embodiment, the number of the first heat dissipation groups 130 is specifically two, and the heating element 110 is connected between the first heat-conducting elements 134 of the two first heat dissipation groups 130. The heat generated by the heating element 110 can be absorbed by the first heat-conducting elements 134 of the two first heat dissipation groups 130 at the same time, and dissipated through the first heat dissipation elements 132 respectively connected to them.

[0173] Since the heating element 110 is connected between the two first heat-conducting elements 134 , heat can be more evenly distributed to the two first heat-conducting elements 134 , thereby improving the efficiency of heat transfer.

[0174] like Figure 8 and Figure 9 As shown, in some embodiments, optionally, the heating element 110 and the first heat dissipation group 130 are recorded as a second heating structure 180, the number of the second heating structures 180 is multiple, and the multiple second heating structures 180 are stacked; in any two adjacent second heating structures 180, the heating element 110 of one second heating structure 180 and the first heat dissipation group 130 of the other second heating structure 180 are connected through a first heat conducting member 134; in the multiple second heating structures 180, the first heat dissipation group 130 is provided on one side of the outermost heating element 110.

[0175] In this technical solution, the heating element 110 and the first heat dissipation group 130 together constitute a second heating structure 180. There are multiple second heating structures 180, and the multiple second heating structures 180 are stacked. Specifically, the multiple second heating structures 180 are stacked along the direction from the first heat dissipation element 132 to the heating element 110. In any two adjacent second heating structures 180, the heating element 110 of one second heating structure 180 and the first heat dissipation group 130 of the other second heating structure 180 are connected by a first heat conducting member 134. In addition, in the multiple second heating structures 180, the first heat dissipation group 130 is provided on one side of the outermost heating element 110.

[0176] Among them, in any two adjacent second heating structures 180, the heating element 110 of one second heating structure 180 and the first heat dissipation group 130 of the other second heating structure 180 are connected by a first heat conducting member 134. This arrangement enables the two adjacent second heating structures 180 to form a continuous heat transfer path, allowing heat to flow between the two adjacent second heating structures 180, further improving the heat transfer efficiency.

[0177] This continuous heat transfer path helps to evenly distribute heat and quickly dissipate heat, thereby improving the heating efficiency of the heating device 100.

[0178] Furthermore, in the plurality of second heating structures 180, a first heat dissipation group 130 is provided on one side of the outermost heating element 110. The first heat dissipation group 130 is responsible for processing the heat generated by the outermost heating element 110, ensuring that this part of the heat can also be effectively dissipated.

[0179] The heat generated by the outermost heating element 110 can be dissipated through the first heat dissipation group 130 .

[0180] It is understood that there are multiple heating elements 110, multiple first heat sinks 132, and multiple first heat conducting elements 134. The number of first heat sinks 132 is greater than the number of heating elements 110, the number of first heat conducting elements 134 is greater than the number of heating elements 110, and the number of first heat conducting elements 134 is greater than the number of first heat sinks 132.

[0181] like Figure 1 and Figure 3 As shown, in some embodiments, optionally, the first heat dissipation member 132 includes: a support plate 194; a second heat conductive member 196, the second heat conductive member 196 is connected between the support plate 194 and the first heat conductive member 134, and the second heat conductive member 196 and the support plate 194 enclose a plurality of heat dissipation channels 150.

[0182] In this embodiment, the first heat sink 132 includes a support plate 194 and a second heat conductor 196. The support plate 194 is the basic structural part of the first heat sink 132. Specifically, the support plate 194 is usually made of a material that is both thermally conductive and has a certain thermal conductivity, such as metal, to provide stable support and basic heat dissipation function.

[0183] The second heat-conducting member 196 is connected between the support plate 194 and the first heat-conducting member 134 . The second heat-conducting member 196 mainly transfers heat from the first heat-conducting member 134 to the support plate 194 so as to further dissipate the heat.

[0184] Specifically, the second heat conducting member 196 is made of a material with high thermal conductivity to ensure that heat can be transferred quickly and effectively.

[0185] The second heat conducting member 196 and the support plate 194 enclose a plurality of heat dissipation channels 150. When heat is transferred to the support plate 194 through the second heat conducting member 196, the heat dissipation channels 150 can guide the heat flow, increase the heat dissipation area, and improve the heat dissipation efficiency so that the heat can be dissipated into the environment more quickly.

[0186] like Figure 1 and Figure 3 As shown, in some embodiments, optionally, the second heat conducting member 196 is a corrugated heat conducting member.

[0187] In this embodiment, the second heat conductor 196 is a wavy heat conductor, which is composed of a series of undulating corrugations. These corrugations can be regarded as countless small heat conducting units. Each heat conducting unit can effectively transfer heat from the high temperature area to the low temperature area. Through the continuous corrugated structure, heat can be evenly distributed on the entire second heat conductor 196.

[0188] The wavy heat conductive member has excellent thermal conductivity and heat dissipation effect. The wavy heat conductive member can quickly dissipate a large amount of heat in a short period of time, thereby improving the heating efficiency of the heating device 100.

[0189] In some embodiments, optionally, the second heat conducting member 196 includes: a plurality of fins, the plurality of fins are arranged at intervals, each fin is connected between the support plate 194 and the first heat conducting member 134 , and any two adjacent fins and the support plate 194 enclose a heat dissipation channel 150 .

[0190] In this embodiment, the second heat conducting member 196 includes a plurality of fins, which are arranged at intervals, thereby not only increasing the heat conducting area but also forming an effective heat transfer path through the connection between the fins, the support plate 194 and the first heat conducting member 134 .

[0191] Each fin acts as a heat-conducting bridge, quickly transferring heat from the high-temperature area to the low-temperature area. At the same time, the spacing between the fins allows air to flow freely, thereby taking away the heat from the fins and improving the heat dissipation efficiency.

[0192] Any two adjacent fins and the support plate 194 enclose a heat dissipation channel 150 . These heat dissipation channels 150 form a natural convection system, so that heat can be removed more quickly through air convection.

[0193] In some embodiments, when the heating device 100 proposed in this application is in use, after the two electrodes 122 of the electrode portion 120 are connected to the "+" and "-" power sources, the heating portion 112 of the heating element 110 can generate far-infrared light waves that can be transmitted to the surrounding area for heating. When the far-infrared light waves are not transmitted, they surround the heating portion 112 and heat it 360 degrees. Only a portion of them can be radiated to the outside. The rest is simultaneously transmitted to the first heat sink 132 (specifically, a heat dissipation corrugated sheet) through the first heat conductive member 134 that is in full contact with the sleeve 116 (specifically, a quartz glass tube). When wind enters the heat dissipation channel 150 and passes through the first heat sink 132, it will carry away the heat from the first heat sink 132 and turn into hot air that is blown to the outside, thereby forming a combined heating method of radiation heating and wind heating.

[0194] The heating device 100 proposed in the present application does not occupy any other space on the basis of the existing size for placing ceramic PTC, and effectively conducts the excess heat from heat radiation to the first heat sink 132 for air heating, thereby improving the heating efficiency.

[0195] Specifically, the first heat-conducting member 134 is a U-shaped heat-conducting member 135. In addition to clamping the heating tube, the U-shaped heat-conducting member 135 can also ensure that the far-infrared light waves emitted by the heating element 110 are only radiated in the direction of the open end 136 of the first heat-conducting member 134. The U-shaped heat-conducting member 135 fixedly reflects and absorbs the heat radiated from the far-infrared heating tube to the U-shaped heat-conducting member 135, and simultaneously absorbs the excess heat radiated to the inside by the heating element 110 and then conducts the heat to the first heat sink 132. When wind enters the heat dissipation channel 150 and passes through the first heat sink 132, the wind will take away the heat on the first heat sink 132 and turn into hot air that is blown to the outside.

[0196] Specifically, the heating element 110 may also adopt various shapes, and the fixing method is not limited to adhesive fixing and slot fixing, but may also be fixed by auxiliary mounting parts such as bolts and other components.

[0197] Specifically, according to different product requirements, the width and size of the heating element 110 can be adjusted as needed. After widening the heating tube, the radiation area can be increased. After the radiation area is increased, the auxiliary heating effect can be increased.
