Description

Technical Field

[0001] The present application relates to the technical field of heating equipment, and in particular, to a heater. Background Art

[0002] In the related art, infrared heaters heat the room by directly radiating heat through infrared heating elements. The direct radiated heat is too concentrated, the radiation range is small, and the heat concentration area is too hot, which greatly reduces the performance of the product. Utility Model Content

[0003] The present 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 proposes a heater.

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

[0006] In view of this, the first aspect of the present application proposes a heater, comprising: a shell assembly, a first air outlet and a second air outlet are provided on the shell assembly, a first chamber, a flow port and a second chamber are provided in the shell assembly, the first chamber connects the first air outlet and the flow port, and the second chamber connects the flow port and the second air outlet; a wind wheel is provided in the first chamber, and the wind wheel is used to guide air from the first air outlet to the second air outlet; a first infrared heating element is provided in the second chamber.

[0007] A heater provided in the present application includes a shell assembly, a wind wheel and a first infrared heating element.

[0008] The housing assembly is provided with a first chamber and a second chamber, the wind wheel is provided in the first chamber, and the first infrared heating element is provided in the second chamber. The first chamber has the function of accommodating the wind wheel, and the second chamber has the function of accommodating the first infrared heating element.

[0009] Furthermore, a flow port is provided in the shell component, a first air port and a second air port are provided on the shell component, the first air port is connected to the first chamber, the flow port is connected to the first chamber, the flow port is also connected to the second chamber, and the second air port is connected to the second chamber. In other words, the first chamber is connected to the first air port and the flow port, and the second chamber is connected to the flow port and the second air port.

[0010] It is understood that the first infrared heating element can emit infrared radiation energy when working. The infrared radiation energy has a longer wavelength and can directly act on the surface of the object to be converted into heat energy to increase the surface temperature of the object. The infrared radiation can be reflected by the wall of the second chamber and radiated out of the heater through the second air outlet.

[0011] When the wind wheel is working, it can guide the air from the first air outlet to the second air outlet, that is, the air enters the first chamber through the first air outlet under the action of the wind wheel, then flows to the second chamber through the flow port, and is discharged from the heater through the second air outlet. When the airflow flows through the first infrared heating element, it helps to diffuse the heat reflected by the first infrared heating element, so as to diffuse the hot air out of the heater through the second air outlet.

[0012] This arrangement helps to diffuse heat and can increase the heat dissipation range of the heater. And because the heat reflected by the first infrared heating element can be diffused under the action of the wind wheel, it can avoid the occurrence of heat concentration, can meet the use requirements of heat without burning sensation and a large heat range, improve the heating effect of the heater, and help improve the use performance and market competitiveness of the heater.

[0013] In addition, since the wind wheel and the first infrared heating element are located in different chambers, specifically, the wind wheel is arranged in the first chamber, and the first infrared heating element is arranged in the second chamber. Therefore, the walls of the first chamber and the second chamber can play a role in heat insulation. In this way, the heat transferred from the second chamber to the wind wheel can be reduced, and the temperature in the first chamber can be reduced. In this way, the damage to the wind wheel can be reduced, which is beneficial to extending the service life of the wind wheel. At the same time, this setting can reduce the situation where part of the heat is discharged through the first air outlet due to the radiation of heat from the first infrared heating element to the wind wheel, which is beneficial to the directional radiation of heat and provides effective and reliable structural support for improving the working efficiency of the heater.

[0014] The heater described above in this application may also have the following additional technical features:

[0015] In some embodiments, optionally, the wind wheel has an outlet portion; the flow port is located between the outlet portion and the first infrared heating element; or the outlet portion and the first infrared heating element are both arranged adjacent to the flow port.

[0016] In this embodiment, the matching structure of the wind wheel, the flow port and the first infrared heating element is further defined.

[0017] The wind wheel has an outlet portion.

[0018] The flow port is located between the outlet portion and the first infrared heating element, that is, at least a portion of the outlet portion and the first infrared heating element are arranged opposite to each other.

[0019] Alternatively, the outlet and the first infrared heating element are both arranged close to the flow opening, that is, the distance from the outlet to the flow opening is shorter, and the distance from the first infrared heating element to the flow opening is shorter.

[0020] This arrangement limits the positional relationship between the outlet of the wind wheel and the first infrared heating element, shortens the distance between the outlet of the wind wheel and the first infrared heating element, enables the airflow discharged from the outlet to act on the first infrared heating element immediately, and achieves the purpose of blowing air to the first infrared heating element. It can ensure the effective contact area between the airflow and the first infrared heating element, and is more conducive to the diffusion of heat emitted from the side of the first infrared heating element away from the outlet, so as to achieve the effect of no burning sensation and expanded heat range.

[0021] In some embodiments, optionally, the first infrared heating element is located between the second air outlet and the flow outlet.

[0022] In this embodiment, the matching structure of the first infrared heating element, the second air outlet and the flow outlet is further defined, so that the first infrared heating element is located between the second air outlet and the flow outlet. In this way, the heat at the first infrared heating element can be quickly radiated out of the heater through the second air outlet, which is more conducive to the diffusion of heat, and is beneficial to increasing the radiation range of heat, thereby helping to improve the working efficiency of the heater.

[0023] In some embodiments, optionally, the shell assembly includes: a shell, the shell is provided with a first air outlet and a second air outlet; a reflection plate is located inside the shell, and the first chamber and the second chamber are enclosed between the reflection plate and the inner surface of the shell.

[0024] In this embodiment, the housing assembly includes a housing and a reflective plate.

[0025] The reflector is located inside the shell, and the reflector is connected to the inner surface of the shell, and a first chamber and a second chamber are enclosed between the reflector and the inner surface of the shell. It can be understood that the reflector has a first end face and a second end face in the thickness direction. The first end face and the inner surface of the shell enclose a first chamber, and the second end face and the inner surface of the shell enclose a second chamber. It can also be said that the reflector separates the internal space of the shell into a first chamber and a second chamber that are connected.

[0026] This arrangement reuses the structure of the reflection plate, which reduces the input of materials used for separation while ensuring the effectiveness and feasibility of forming the first chamber and the second chamber, which is beneficial to reducing the production cost of the product.

[0027] It can be understood that the reflective plate has the function of reflecting heat, so that the heat can be effectively diffused out of the heater through the second air outlet under the action of the airflow.

[0028] In some embodiments, optionally, the reflecting plate is provided with a flow port and a reflecting groove, and the first infrared heating element is provided on the reflecting plate; the reflecting groove and the first infrared heating element are located on the same side of the reflecting plate, and the reflecting groove is located on one side of the flow port; the heater also includes a second infrared heating element, and the second infrared heating element is provided in the reflecting groove.

[0029] In this embodiment, the reflector has a first end surface and a second end surface in the thickness direction, and the reflector is provided with a flow opening, which penetrates the first end surface and the second end surface and communicates with the first cavity and the second cavity.

[0030] It can be understood that the first infrared heating element is arranged on the reflecting plate, and the reflecting plate serves as a mounting carrier of the first infrared heating element, and has the function of installing and fixing the first infrared heating element, and can ensure the function of the first infrared heating element, the flow port and the outlet of the wind wheel.

[0031] The structure of the heater is further defined such that the heater further includes a second infrared heating element.

[0032] The reflective plate is provided with a reflective groove, and the reflective groove and the first infrared heating element are located on the same side of the reflective plate. That is, the reflective plate is provided with a reflective groove on one side where the first infrared heating element is provided.

[0033] The second infrared heating element is arranged in the reflection groove, and the reflection plate serves as a mounting carrier of the second infrared heating element and has the function of mounting and fixing the second infrared heating element.

[0034] The position of the reflective groove relative to the first infrared heating element is fixed, so the relative position relationship between the first infrared heating element and the second infrared heating element can be defined.

[0035] By limiting the positional relationship between the reflection groove and the second infrared heating element, the reflection groove has the function of reflecting heat, so that the heat at the second infrared heating element can be effectively diffused out of the heater through the second air outlet under the action of airflow.

[0036] It can be understood that by providing the first infrared heating element and the second infrared heating element, the number of heating elements for generating heat is increased, which can increase the heat generated when the heater is working, and is beneficial to improving the working efficiency of the heater.

[0037] It is understandable that the first infrared heating element is arranged opposite to the flow port, the second infrared heating element is located on one side of the flow port, and the second infrared heating element is not arranged opposite to the flow port. In this way, the effectiveness of the airflow flowing to the second chamber through the flow port can be ensured, and the amount of heat in the second chamber flowing to the first chamber through the flow port can be reduced. Reliable structural support is provided to ensure the working efficiency of the heater.

[0038] Optionally, the reflective groove includes an arc groove, a spherical groove, etc., which are not listed here one by one.

[0039] In some embodiments, optionally, there are multiple reflecting grooves and multiple second infrared heating elements, and at least one second infrared heating element is arranged in each reflecting groove; a part of the multiple reflecting grooves is located on one side of the first infrared heating element, and another part of the multiple reflecting grooves is located on the other side of the first infrared heating element.

[0040] In this embodiment, the number of the reflecting grooves and the second infrared heating element is further limited, and the matching structure of the reflecting grooves, the second infrared heating element and the first infrared heating element is defined.

[0041] The number of the reflecting grooves and the number of the second infrared heating elements are both plural, that is, the number of the reflecting grooves is plural, and the number of the second infrared heating elements is plural.

[0042] The first infrared heating element has a first side and a second side opposite to each other, a portion of the plurality of reflection grooves are located on the first side of the first infrared heating element, and another portion of the plurality of reflection grooves are located on the second side of the first infrared heating element.

[0043] Wherein, at least one second infrared heating element is arranged in each reflecting groove, that is, at least one second infrared heating element is arranged in any reflecting groove among the plurality of reflecting grooves.

[0044] This setting rationally arranges the matching structure of the first infrared heating element and multiple second infrared heating elements, which can ensure the balance and consistency of the radiant heat at different positions of the second chamber. In this way, the balance and consistency of the radiant heat of the heater can be ensured, and the situation of excessive burning caused by the concentration of heat in some areas can be effectively avoided, which is beneficial to improving the working efficiency of the heater.

[0045] In some embodiments, optionally, a mounting groove is provided on a side of the reflective plate facing the wind wheel, the flow port is provided in the mounting groove, and a portion of the wind wheel extends into the mounting groove.

[0046] In this embodiment, the structure of the reflective plate is further defined, and a mounting groove is provided on the side of the reflective plate facing the wind wheel, that is, the reflective groove and the mounting groove of the reflective plate are located on different sides of the reflective plate.

[0047] It is understandable that the flow port is arranged in the mounting groove, and a part of the wind wheel extends into the mounting groove. This arrangement can reduce the distance between the outlet of the wind wheel and the first infrared heating element, and can enhance the efficiency of heat radiation. At the same time, the structural arrangement of the mounting groove can enhance the structural strength of the reflector, which is conducive to reducing the deformation of the reflector.

[0048] The matching structure of the wind wheel and the mounting groove is conducive to reducing the size of the heater in the direction from the first infrared heating element to the wind wheel, which is conducive to achieving lightweight products.

[0049] It can be understood that the wind wheel includes a volute, and at least a portion of the volute extends into the mounting groove.

[0050] In some embodiments, optionally, a peripheral side wall of the shell is provided with a first air outlet and a second air outlet.

[0051] In this embodiment, the matching structure of the housing, the first air outlet and the second air outlet is further defined.

[0052] The shell has a peripheral side wall, and the peripheral side wall of the shell is provided with a first air outlet and a second air outlet.

[0053] That is, the first air outlet and the second air outlet are located at the side of the shell. This arrangement can ensure the heat radiation range and also meet the use requirements of aesthetic appearance.

[0054] In some embodiments, optionally, the shell includes: a base; a top cover, opposite to the base and arranged at intervals; a panel group, connected between the base and the top cover, the panel group is provided with a first air outlet and a second air outlet; the direction from the base to the top cover is recorded as the height direction; the dimension of the panel group in the height direction is recorded as L1, and the dimension of the panel group perpendicular to the height direction is recorded as L2, L1 is greater than L2; wherein the first infrared heating element and the outlet portion both extend along the height direction.

[0055] In this embodiment, the housing includes a base, a top cover and a panel set. The base and the top cover are arranged opposite to each other, a first end of the panel set is connected to the base, and a second end of the panel set is connected to the top cover. That is, the panel set is connected between the base and the top cover.

[0056] The enclosure group is provided with a first air outlet and a second air outlet to meet the use requirements of the peripheral side wall of the shell being provided with a first air outlet and a second air outlet.

[0057] The direction from the base to the top cover is recorded as the height direction. The dimension of the panel group in the height direction is recorded as L1, and the dimension of the panel group perpendicular to the height direction is recorded as L2, and L1 is greater than L2.

[0058] That is, the height of the housing is greater than the width of the housing in the first direction, and the height of the housing is greater than the width of the housing in the second direction. Any two of the first direction, the second direction and the height direction are perpendicular to each other.

[0059] For example, the shell has a cylindrical structure; for example, the shell has a barrel-shaped structure.

[0060] The first infrared heating element and the outlet portion both extend in the height direction, that is, the first infrared heating element extends in the height direction, and the outlet portion extends in the height direction. It can be seen that the first infrared heating element extends in the direction of the larger size of the shell. This is conducive to increasing the volume of the first infrared heating element and increasing the heat generated by the first infrared heating element per unit time.

[0061] It can be understood that the first infrared heating element and the outlet portion both extend in the height direction, and this arrangement enables different positions of the first infrared heating element to effectively contact the airflow flowing out of the outlet portion of the wind wheel, which is beneficial to heat radiation. It can also be said that the outlet portion of the wind wheel and the first infrared heating element are both arranged in the length direction of the wind wheel, that is, the wind wheel, the first infrared heating element and the reflective plate are all placed vertically.

[0063] In this embodiment, the structure of the enclosure panel group is further defined so that the enclosure panel group includes a mesh panel and a cover shell.

[0064] The mesh plate forms a second air outlet, which can increase the area of ​​the second air outlet and is conducive to heat dissipation. In addition, the structural setting also has the function of preventing dust and the like from entering the heater through the second air outlet.

[0065] The cover shell is connected to the mesh plate, and the cover shell, the mesh plate, the base and the top cover enclose a space for accommodating the wind wheel and the first infrared heating element.

[0066] In some embodiments, optionally, the wind wheel further has an inlet portion, and the inlet portion is connected to the first air outlet.

[0067] In this embodiment, the matching structure between the wind wheel and the first air outlet is further defined.

[0068] The wind wheel also has an inlet portion, which is connected to the first air outlet, and the outlet portion of the wind wheel is connected to the flow port. This arrangement can limit the flow path of the airflow entering the shell through the first air outlet, so that the airflow is effectively guided to the first infrared heating element.

[0069] In some embodiments, optionally, the heater further includes: a ground foot connected to the shell assembly, and the ground foot is used to support the shell assembly.

[0070] In this embodiment, the structure of the heater is further limited so that the heater also includes feet, which are connected to the shell assembly. The feet are used to support and fix the shell assembly to separate the shell assembly from a loading surface (such as a desktop, cabinet, countertop, and ground, etc., which are not listed here one by one), thereby preventing heat from directly contacting the loading surface to cause heat loss.

[0071] In some embodiments, optionally, the wind wheel includes any one of the following or a combination thereof: a cross-flow wind wheel, an axial flow wind wheel and a centrifugal wind wheel.

[0072] In this embodiment, the type of the wind wheel is further defined such that the wind wheel includes any one of the following or a combination thereof: a cross-flow wind wheel, an axial-flow wind wheel, and a centrifugal wind wheel.

[0073] That is, the wind wheel includes a cross-flow wind wheel, and / or the wind wheel includes an axial flow wind wheel, and / or the wind wheel includes a centrifugal wind wheel.

[0074] The second aspect of the present application proposes a heater, comprising: a shell, the shell being provided with a first air outlet and a second air outlet; a reflective plate, arranged in the shell, the front side of the reflective plate being provided with a flow outlet and at least two reflective grooves, the flow outlet connecting the first air outlet and the second air outlet, a part of at least two reflective grooves being located on one side of the flow outlet, and another part of at least two reflective grooves being located on the other side of the flow outlet; a wind wheel, arranged in the shell, the wind wheel being located on the back side of the reflective plate, and the wind wheel having an outlet portion; a first infrared heating element, located on the front side of the reflective plate, the flow outlet being located between the outlet portion and the first infrared heating element; a plurality of second infrared heating elements, at least one second infrared heating element being provided in each reflective groove; wherein the wind wheel works to drive external airflow to enter the shell from the first air outlet, flow to the front side of the reflective plate through the flow outlet, and then flow out of the shell through the second air outlet.

[0075] A heater provided in the present application includes a shell, a reflection plate, a wind wheel, a first infrared heating element and a plurality of second infrared heating elements.

[0076] The reflecting plate, the wind wheel, the first infrared heating element and the plurality of second infrared heating elements are all arranged in the shell.

[0077] The shell body is provided with a first air outlet and a second air outlet, the reflecting plate is provided with a flow outlet, and the flow outlet is connected with the first air outlet and the second air outlet.

[0078] The first infrared heating element and the second infrared heating element can both emit infrared radiation energy when working. The infrared radiation energy has a longer wavelength and can directly act on the surface of the object to be converted into heat energy to increase the surface temperature of the object. The infrared radiation can be reflected by the reflector and radiated out of the heater through the second air outlet.

[0079] When the wind wheel is working, it can guide the air from the first air outlet to the second air outlet, that is, the air enters the shell through the first air outlet under the action of the wind wheel, and then flows to the front of the reflective plate through the flow port, and is discharged from the heater through the second air outlet under the reflection effect of the reflective plate.

[0080] When the airflow flows through the first infrared heating element, it helps to diffuse the heat reflected by the first infrared heating element, so as to diffuse the hot air out of the heater through the second air outlet.

[0081] The airflow flows through the flow port to the front of the reflective plate, and the reflective groove has the function of reflecting heat, so that the heat at the second infrared heating element can be effectively diffused out of the heater through the second air outlet under the action of the airflow.

[0082] It can be understood that by providing the first infrared heating element and the second infrared heating element, the number of heating elements for generating heat is increased, which can increase the heat generated when the heater is working, and is beneficial to improving the working efficiency of the heater.

[0083] This arrangement helps to diffuse heat and can increase the heat dissipation range of the heater. And because the heat reflected by the first infrared heating element and the second infrared heating element can be diffused under the action of the wind wheel, it can avoid the occurrence of heat concentration, can meet the use requirements of heat without burning sensation and a large heat range, improve the heating effect of the heater, and help improve the use performance and market competitiveness of the heater.

[0084] In addition, the flow port is located between the outlet of the wind wheel and the first infrared heating element, and the flow port is located between the plurality of second infrared heating elements. In this way, the effectiveness of the airflow flowing to the reflector through the flow port can be ensured, and the amount of heat at the front of the reflector flowing to the back of the reflector through the flow port can be reduced. Reliable structural support is provided to ensure the working efficiency of the heater.

[0085] It can be understood that the reflective plate has the function of reflecting heat, so that the heat can be effectively diffused out of the heater through the second air outlet under the action of the airflow.

[0086] At the same time, since the wind wheel, the first infrared heating element and the second infrared heating element are located on different sides of the reflecting plate, specifically, the wind wheel is located on the back of the reflecting plate, and the first infrared heating element and the second infrared heating element are both located on the front of the reflecting plate. Therefore, the reflecting plate can play a role in heat insulation. In this way, the amount of heat transferred from the first infrared heating element and the second infrared heating element to the wind wheel can be reduced, and the temperature at the wind wheel can be reduced. In this way, the damage to the wind wheel can be reduced, which is beneficial to extending the service life of the wind wheel. At the same time, this setting can reduce the situation where part of the heat is discharged through the first air outlet due to the radiation of heat from the first infrared heating element and the second infrared heating element to the wind wheel, which is beneficial to the directional radiation of heat and provides effective and reliable structural support for improving the working efficiency of the heater.

[0087] In some embodiments, optionally, the wind wheel is a cross-flow wind wheel, and the outlet of the cross-flow wind wheel, the first infrared heating element, the second infrared heating element and the flow opening of the reflective plate all extend along the height direction of the shell; the dimension of the shell in the height direction is denoted as L1, and the dimension of the shell in the direction perpendicular to the height is denoted as L2, and L1 is greater than L2.

[0088] In this embodiment, the matching structure of the housing, the wind wheel, the reflection plate, the first infrared heating element and the second infrared heating element is further defined.

[0089] The height direction is either the direction from the bottom to the top of the shell or the direction from the top to the bottom of the shell. The height dimension of the shell is L1, and the dimension of the shell perpendicular to the height direction is L2, where L1 is greater than L2.

[0090] That is, the height of the housing is greater than the width of the housing in the first direction, and the height of the housing is greater than the width of the housing in the second direction. Any two of the first direction, the second direction and the height direction are perpendicular to each other.

[0091] The outlet of the crossflow wind wheel, the first infrared heating element, the second infrared heating element and the flow opening of the reflective plate all extend in the height direction of the shell, that is, the outlet of the crossflow wind wheel extends in the height direction of the shell, the first infrared heating element extends in the height direction of the shell, the second infrared heating element extends in the height direction of the shell, and the flow opening of the reflective plate extends in the height direction of the shell. It can be seen that the outlet of the crossflow wind wheel, the first infrared heating element, the second infrared heating element and the flow opening of the reflective plate all extend in the direction of the larger size of the shell. Optionally, the outlet of the wind wheel, the first infrared heating element, the second infrared heating element and the flow opening of the reflective plate are all arranged along the length direction of the wind wheel. That is, the wind wheel, the first infrared heating element, the second infrared heating element and the reflective plate are all placed vertically.

[0092] This is conducive to increasing the volume of the first infrared heating element and the second infrared heating element, and is conducive to increasing the amount of heat generated per unit time. In addition, this arrangement enables different positions of the first infrared heating element and the second infrared heating element to effectively contact the airflow flowing out of the outlet of the wind wheel, which is conducive to heat radiation.

[0118] When the wind wheel 200 is working, it can guide air from the first air port 110 to the second air port 120, that is, under the action of the wind wheel 200, the air enters the first chamber 130 through the first air port 110, then flows to the second chamber 140 through the flow port 150, and is discharged from the heater 10 through the second air port 120. When the airflow flows through the first infrared heating element 300, it helps to diffuse the heat reflected by the first infrared heating element 300, so as to diffuse the hot air out of the heater 10 through the second air port 120.

[0119] This arrangement helps to diffuse heat and can increase the heat dissipation range of the heater 10. And because the heat reflected by the first infrared heating element 300 can be diffused under the action of the wind wheel 200, it can avoid the occurrence of heat concentration, can meet the use requirements of heat without burning sensation and a large heat range, improve the heating effect of the heater 10, and help improve the use performance and market competitiveness of the heater 10.

[0120] In addition, since the wind wheel 200 and the first infrared heating element 300 are located in different chambers, specifically, the wind wheel 200 is arranged in the first chamber 130, and the first infrared heating element 300 is arranged in the second chamber 140. Therefore, the cavity walls of the first chamber 130 and the second chamber 140 can play a role in heat insulation. In this way, the heat transferred from the second chamber 140 to the wind wheel 200 can be reduced, and the temperature in the first chamber 130 can be reduced. In this way, the damage to the wind wheel 200 can be reduced, which is conducive to extending the service life of the wind wheel 200. At the same time, this setting can reduce the situation where part of the heat is discharged through the first air outlet due to the radiation of the heat at the first infrared heating element 300 to the wind wheel 200, which is conducive to the directional radiation of heat and provides effective and reliable structural support for improving the working efficiency of the heater 10.

[0121] In some embodiments, optionally, Figure 4 As shown, the wind wheel 200 has an outlet portion 210 ; the flow opening 150 is located between the outlet portion 210 and the first infrared heating element 300 ; or the outlet portion 210 and the first infrared heating element 300 are both arranged adjacent to the flow opening 150 .

[0122] In this embodiment, the matching structure of the wind wheel 200, the flow opening 150 and the first infrared heating element 300 is further defined.

[0123] The wind wheel 200 has an outlet portion 210 .

[0124] The flow opening 150 is located between the outlet portion 210 and the first infrared heating element 300 , that is, at least a portion of the outlet portion 210 and the first infrared heating element 300 are disposed opposite to each other.

[0125] Alternatively, the outlet portion 210 and the first infrared heating element 300 are both disposed adjacent to the flow opening 150. That is, the distance from the outlet portion 210 to the flow opening 150 is shorter, and the distance from the first infrared heating element 300 to the flow opening 150 is shorter.

[0126] This arrangement limits the positional relationship between the outlet portion 210 of the wind wheel 200 and the first infrared heating element 300, shortens the distance between the outlet portion 210 of the wind wheel 200 and the first infrared heating element 300, enables the airflow discharged from the outlet portion 210 to act on the first infrared heating element 300 at the first time, and achieves the purpose of blowing air to the first infrared heating element 300, can ensure the effective contact area between the airflow and the first infrared heating element 300, and is more conducive to the diffusion of heat emitted from the side of the first infrared heating element 300 away from the outlet portion 210, and can achieve the effect of heat without burning sensation and expanding the heat range.

[0127] Optionally, the outlet portion 210 is connected to the flow port 150 .

[0128] Optionally, the outlet portion 210 is opposite to the flow opening 150 and is arranged at an interval.

[0129] Optionally, at least a portion of the first infrared heating element 300 covers the outlet portion 210 .

[0130] Optionally, the first infrared heating element 300 and the flow opening 150 are arranged at an interval, which is helpful to reduce the resistance of the airflow when it flows through the first infrared heating element 300.

[0131] In some embodiments, optionally, the first infrared heating element 300 is located between the second air port 120 and the flow port 150 .

[0132] In this embodiment, the matching structure of the first infrared heating element 300, the second air outlet 120 and the flow outlet 150 is further defined, so that the first infrared heating element 300 is located between the second air outlet 120 and the flow outlet 150. In this way, the heat at the first infrared heating element 300 can be quickly radiated out of the heater 10 through the second air outlet 120, which is more conducive to the diffusion of heat, and is conducive to increasing the radiation range of heat, and further conducive to improving the working efficiency of the heater 10.

[0133] In some embodiments, optionally, Figure 3 , Figure 4 and Figure 5 As shown, the housing assembly 100 includes a housing 160 and a reflective plate 170 .

[0134] The housing 160 is provided with a first air outlet 110 and a second air outlet 120 .

[0135] The reflective plate 170 is located inside the housing 160 .

[0136] The reflective plate 170 and the inner surface of the housing 160 enclose a first chamber 130 and a second chamber 140 .

[0137] In this embodiment, the housing assembly 100 includes a housing 160 and a reflective plate 170 .

[0138] The reflector 170 is located in the housing 160, and the reflector 170 is connected to the inner surface of the housing 160, and the first chamber 130 and the second chamber 140 are enclosed between the reflector 170 and the inner surface of the housing 160. It can be understood that the reflector 170 has a first end face and a second end face in the thickness direction. The first chamber 130 is enclosed between the first end face and the inner surface of the housing 160, and the second chamber 140 is enclosed between the second end face and the inner surface of the housing 160. It can also be said that the reflector 170 separates the internal space of the housing 160 into the first chamber 130 and the second chamber 140 that are connected.

[0139] This arrangement reuses the structure of the reflection plate 170 , and while ensuring the effectiveness and feasibility of forming the first chamber 130 and the second chamber 140 , reduces the input of materials for separation, which is beneficial to reducing the production cost of the product.

[0140] It can be understood that the reflective plate 170 has the function of reflecting heat, so that the heat can be effectively diffused out of the heater 10 through the second air outlet 120 under the action of the air flow.

[0141] Optionally, the reflective plate 170 includes a stainless steel reflective plate, an aluminum alloy reflective plate, a ceramic reflective plate, etc., which are not listed here one by one.

[0142] It is understandable that the reflective plate 170 has the function of reflecting the infrared rays emitted by the first infrared heating element 300 and / or the second infrared heating element 400. Because the reflective plate 170 is arranged away from the second air outlet 120, part of the infrared rays emitted by the first infrared heating element 300 and / or the second infrared heating element 400 will be emitted in a direction away from the second air outlet 120, and by arranging the reflective plate 170, the reflective plate 170 is used to reflect this part of the infrared rays, so that more infrared rays can be emitted through the second air outlet 120.

[0143] In some embodiments, optionally, Figure 4 and Figure 5 As shown, the reflection plate 170 is provided with a flow port 150 and a reflection groove 172 , and the first infrared heating element 300 is disposed on the reflection plate 170 .

[0144] The reflection groove 172 and the first infrared heating element 300 are located on the same side of the reflection plate 170 , and the reflection groove 172 is located on one side of the flow port 150 .

[0145] The heater 10 further includes a second infrared heating element 400 .

[0146] The second infrared heating element 400 is disposed in the reflection groove 172 .

[0147] In this embodiment, the reflector 170 has a first end surface and a second end surface in the thickness direction, and the reflector 170 is provided with a flow opening 150, which penetrates the first end surface and the second end surface and connects the first chamber with the second chamber.

[0148] It can be understood that the first infrared heating element 300 is arranged on the reflecting plate 170, and the reflecting plate 170 serves as an installation carrier of the first infrared heating element 300, and has the function of installing and fixing the first infrared heating element 300, and can ensure the functions of the first infrared heating element 300, the flow port 150 and the outlet part 210 of the wind wheel 200.

[0149] The structure of the heater 10 is further defined such that the heater 10 further includes a second infrared heating element 400 .

[0150] The reflective plate 170 is provided with a reflective groove 172, and the reflective groove 172 and the first infrared heating element 300 are located on the same side of the reflective plate 170. That is, the reflective groove 172 is also provided on the side of the reflective plate 170 where the first infrared heating element 300 is provided.

[0151] The second infrared heating element 400 is disposed in the reflection groove 172 , and the reflection plate 170 serves as a mounting carrier of the second infrared heating element 400 , and has the function of mounting and fixing the second infrared heating element 400 .

[0152] The position of the reflective groove 172 relative to the first infrared heating element 300 is fixed, so the relative position relationship between the first infrared heating element 300 and the second infrared heating element 400 can be defined.

[0153] By limiting the positional relationship between the reflection groove 172 and the second infrared heating element 400 , the reflection groove 172 has the function of reflecting heat, so that the heat at the second infrared heating element 400 can be effectively diffused out of the heater 10 through the second air outlet 120 under the action of airflow.

[0154] It is understandable that by providing the first infrared heating element 300 and the second infrared heating element 400 , the number of heating elements for generating heat is increased, which can increase the heat generated by the heater 10 when it is working, which is beneficial to improving the working efficiency of the heater 10 .

[0155] It can be understood that the first infrared heating element 300 is arranged opposite to the flow port 150, the second infrared heating element 400 is located on one side of the flow port 150, and the second infrared heating element 400 is not arranged opposite to the flow port 150. In this way, the effectiveness of the airflow flowing to the second chamber 140 through the flow port 150 can be ensured, and the amount of heat in the second chamber 140 flowing to the first chamber 130 through the flow port 150 can be reduced. Reliable structural support is provided to ensure the working efficiency of the heater 10.

[0156] Optionally, the reflective groove 172 includes an arc-shaped groove, a spherical groove, etc., which are not listed here one by one.

[0157] In some embodiments, optionally, Figure 4 As shown, the number of the reflection grooves 172 and the number of the second infrared heating elements 400 are both plural.

[0158] At least one second infrared heating element 400 is disposed in each reflection groove 172 .

[0159] A portion of the plurality of reflective grooves 172 is located at one side of the first infrared heating element 300 .

[0160] Another portion of the plurality of reflective grooves 172 is located at the other side of the first infrared heating element 300 .

[0161] In this embodiment, the number of the reflection grooves 172 and the second infrared heating element 400 is further limited, and the matching structure of the reflection grooves 172, the second infrared heating element 400 and the first infrared heating element 300 is further limited.

[0162] The number of the reflection grooves 172 and the number of the second infrared heating elements 400 are both plural, that is, the number of the reflection grooves 172 is plural, and the number of the second infrared heating elements 400 is plural.

[0163] The first infrared heating element 300 has a first side and a second side that are oppositely disposed. A portion of the plurality of reflection grooves 172 is located on the first side of the first infrared heating element 300 , and another portion of the plurality of reflection grooves 172 is located on the second side of the first infrared heating element 300 .

[0164] At least one second infrared heating element 400 is disposed in each reflection groove 172 , that is, at least one second infrared heating element 400 is disposed in any reflection groove 172 among the plurality of reflection grooves 172 .

[0165] This setting rationally arranges the matching structure of the first infrared heating element 300 and multiple second infrared heating elements 400, which can ensure the balance and consistency of the radiant heat at different positions of the second chamber 140. In this way, the balance and consistency of the radiant heat of the heater 10 can be ensured, and the situation of excessive burning caused by the concentration of heat in a certain area can be effectively avoided, which is beneficial to improving the working efficiency of the heater 10.

[0166] In some embodiments, optionally, Figure 4 As shown, a mounting groove 174 is provided on the side of the reflector 170 facing the wind wheel 200 .

[0167] The flow port 150 is disposed in the mounting groove 174 .

[0168] A portion of the wind wheel 200 extends into the mounting groove 174 .

[0169] In this embodiment, the structure of the reflective plate 170 is further defined, and a mounting groove 174 is provided on one side of the reflective plate 170 facing the wind wheel 200. That is, the reflective groove 172 and the mounting groove 174 of the reflective plate 170 are located on different sides of the reflective plate 170.

[0170] It is understandable that the flow port 150 is arranged in the mounting groove 174, and a part of the wind wheel 200 extends into the mounting groove 174. This arrangement can reduce the distance between the outlet portion 210 of the wind wheel 200 and the first infrared heating element 300, and can enhance the efficiency of heat radiation. At the same time, the structural arrangement of the mounting groove 174 can enhance the structural strength of the reflector 170, which is conducive to reducing the deformation of the reflector 170.

[0171] The matching structure of the wind wheel 200 and the mounting groove 174 is conducive to reducing the size of the heater 10 in the direction from the first infrared heating element 300 to the wind wheel 200 .

[0172] Optionally, at least a portion of the outlet portion 210 of the wind wheel 200 extends into the mounting groove 174 .

[0173] Optionally, the distance from the second infrared heating element 400 to the second air outlet 120 is equal to the distance from the first infrared heating element 300 to the second air outlet 120 .

[0174] Optionally, the distance from the second infrared heating element 400 to the second air outlet 120 is smaller than the distance from the first infrared heating element 300 to the second air outlet 120 .

[0175] Optionally, the distance from the second infrared heating element 400 to the second air outlet 120 is greater than the distance from the first infrared heating element 300 to the second air outlet 120 .

[0176] It can be understood that the wind wheel 200 includes a volute, and at least a portion of the volute extends into the mounting groove 174 .

[0177] In some embodiments, optionally, Figure 2 and Figure 3 As shown, a first air outlet 110 and a second air outlet 120 are provided on the peripheral side wall of the housing 160 .

[0178] In this embodiment, the matching structure of the housing 160 , the first air outlet 110 , and the second air outlet 120 is further defined.

[0179] The housing 160 has a peripheral side wall, and the peripheral side wall of the housing 160 is provided with a first air port 110 and a second air port 120 .

[0180] That is, the first air outlet 110 and the second air outlet 120 are located at the side of the housing 160. This arrangement can ensure the heat radiation range and also meet the use requirements of aesthetic appearance.

[0181] In some embodiments, optionally, Figure 3 , Figure 4 and Figure 5 As shown, the housing 160 includes a base 162 , a top cover 164 and a shroud set 166 .

[0182] The top cover 164 is opposite to the base 162 and is spaced apart from each other.

[0183] The enclosure panel set 166 is connected between the base 162 and the top cover 164 .

[0184] The enclosure assembly 166 is provided with a first air outlet 110 and a second air outlet 120 .

[0185] The direction from the base 162 to the top cover 164 is referred to as the height direction.

[0186] The dimension of the enclosure panel set 166 in the height direction is denoted as L1.

[0187] The dimension of the enclosure panel set 166 in the direction perpendicular to the height is denoted as L2.

[0188] L1 is greater than L2.

[0189] The first infrared heating element 300 and the outlet portion 210 both extend in the height direction.

[0190] In this embodiment, the housing 160 includes a base 162, a top cover 164, and a panel set 166. The base 162 and the top cover 164 are arranged opposite to each other and spaced apart, a first end of the panel set 166 is connected to the base 162, and a second end of the panel set 166 is connected to the top cover 164. That is, the panel set 166 is connected between the base 162 and the top cover 164.

[0191] The enclosure group 166 is provided with a first air port 110 and a second air port 120 to meet the use requirement that the peripheral side wall of the shell 160 is provided with the first air port 110 and the second air port 120 .

[0192] The direction from the base 162 to the top cover 164 is recorded as the height direction. The dimension of the enclosure group 166 in the height direction is recorded as L1, and the dimension of the enclosure group 166 perpendicular to the height direction is recorded as L2, and L1 is greater than L2.

[0193] That is, the height of the housing 160 is greater than the width of the housing 160 in the first direction, and the height of the housing 160 is greater than the width of the housing 160 in the second direction. Any two of the first direction, the second direction and the height direction are perpendicular to each other.

[0194] For example, the housing 160 is a columnar structure; for example, the housing 160 is a barrel-shaped structure.

[0195] The first infrared heating element 300 and the outlet portion 210 both extend in the height direction, that is, the first infrared heating element 300 extends in the height direction, and the outlet portion 210 extends in the height direction. It can be seen that the first infrared heating element 300 extends in the direction of the larger size of the housing 160. In this way, it is beneficial to increase the volume of the first infrared heating element 300 and to increase the heat generated by the first infrared heating element 300 per unit time.

[0196] It can be understood that the first infrared heating element 300 and the outlet portion 210 are both extended in the height direction, and this arrangement enables different positions of the first infrared heating element 300 to effectively contact the airflow flowing out of the outlet portion 210 of the wind wheel 200, which is beneficial to heat radiation. It can also be said that the outlet portion 210 of the wind wheel 200 and the first infrared heating element 300 are both arranged in the length direction of the wind wheel 200, that is, the wind wheel 200, the first infrared heating element 300 and the reflective plate 170 are all placed in the vertical direction.

[0197] In some embodiments, optionally, Figure 3 As shown, the enclosure panel set 166 includes a mesh panel 1662 and a cover shell 1664 .

[0198] The mesh plate 1662 forms the second air outlet 120 .

[0199] The cover 1664 is connected to the mesh plate 1662 , and the cover 1664 is provided with a first air outlet 110 .

[0200] In this embodiment, the structure of the enclosure group 166 is further defined such that the enclosure group 166 includes a mesh plate 1662 and a cover shell 1664 .

[0201] The mesh plate 1662 forms the second air outlet 120 , which can increase the area of ​​the second air outlet 120 , which is beneficial to heat dissipation. In addition, the structural setting can also prevent dust and the like from entering the heater 10 through the second air outlet 120 .

[0202] The cover 1664 is connected to the mesh plate 1662 , and the cover 1664 , the mesh plate 1662 , the base 162 and the top cover 164 enclose a space for accommodating the wind wheel 200 and the first infrared heating element 300 .

[0203] In some embodiments, optionally, Figure 4 As shown, the wind wheel 200 further has an inlet portion 220 , and the inlet portion 220 is connected to the first air port 110 .

[0204] In this embodiment, the matching structure between the wind wheel 200 and the first air outlet 110 is further defined.

[0205] The wind wheel 200 also has an inlet portion 220, which is connected to the first air port 110, and the outlet portion 210 of the wind wheel 200 is connected to the flow port 150. This arrangement can limit the flow path of the airflow entering the shell 160 through the first air port 110, so that the airflow is effectively guided to the first infrared heating element 300.

[0206] Optionally, at least a portion of the first air outlet 110 is disposed opposite to the second air outlet 120 .

[0207] Optionally, the first air outlet 110 and the second air outlet 120 are arranged in a staggered manner.

[0208] In some embodiments, optionally, Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the heater 10 further includes a foot 500 .

[0209] The base pin 500 is connected to the housing assembly 100 .

[0210] The feet 500 are used to support the housing assembly 100 .

[0211] In this embodiment, the structure of the heater 10 is further limited, so that the heater 10 also includes a foot 500, and the foot 500 is connected to the shell assembly 100. The foot 500 is used to support and fix the shell assembly 100 so as to separate the shell assembly 100 from the load surface (such as a desktop, cabinet, countertop, and ground, etc., which are not listed here one by one), thereby preventing heat from directly contacting the load surface to cause heat loss.

[0212] In some embodiments, optionally, the wind wheel 200 includes any one of the following or a combination thereof: a cross-flow wind wheel, an axial flow wind wheel, and a centrifugal wind wheel.

[0213] In this embodiment, the type of the wind wheel 200 is further defined, such that the wind wheel 200 includes any one of the following or a combination thereof: a cross-flow wind wheel, an axial-flow wind wheel, and a centrifugal wind wheel.

[0214] That is, the wind wheel 200 includes a cross-flow wind wheel, and / or the wind wheel 200 includes an axial flow wind wheel, and / or the wind wheel 200 includes a centrifugal wind wheel.

[0215] Optionally, a cross-flow wind wheel is added to the rear of the first infrared heating element 300. The cross-flow wind wheel is operated to blow air, so that the heat reflected from the front of the first infrared heating element 300 (such as the first infrared heating tube) can be diffused, thereby achieving the effect of no burning sensation and a wide range of heat. The heat will not be too concentrated, there will be no burning sensation, and the heat will become soft when the wind is blown by the wind wheel 200, achieving a better heating state.

[0216] Alternatively, if Figure 1 As shown, the heater 10 further includes a motor 600 , and the motor 600 is used to drive the wind wheel 200 to work.

[0217] Understandably, Figure 1 and Figure 4 The arrows in the figure indicate the flow path of the air flow.

[0218] It is understandable that the first infrared heating element 300 and the second infrared heating element 400 can generate infrared rays when working, and heat through the infrared rays to provide heat to the user or heat other objects.

[0219] The heater 10 includes a housing assembly 100 , a wind wheel 200 and a first infrared heating element 300 .

[0220] The housing assembly 100 is provided with a first chamber 130 and a second chamber 140, the wind wheel 200 is provided in the first chamber 130, and the first infrared heating element 300 is provided in the second chamber 140. The first chamber 130 has the function of accommodating the wind wheel 200, and the second chamber 140 has the function of accommodating the first infrared heating element 300.

[0221] Furthermore, a flow port 150 is provided in the housing assembly 100, and a first air port 110 and a second air port 120 are provided on the housing assembly 100. The first air port 110 is communicated with the first chamber 130, the flow port 150 is communicated with the first chamber 130, the flow port 150 is also communicated with the second chamber 140, and the second air port 120 is communicated with the second chamber 140. In other words, the first chamber 130 is connected with the first air port 110 and the flow port 150, and the second chamber 140 is connected with the flow port 150 and the second air port 120.

[0222] It is understood that the first infrared heating element 300 can emit infrared radiation energy when working. The infrared radiation energy has a longer wavelength and can directly act on the surface of an object to be converted into heat energy to increase the surface temperature of the object. The infrared radiation energy is reflected by the wall of the second chamber 140 and radiated out of the heater 10 through the second air outlet 120.

[0223] When the wind wheel 200 is working, it can guide air from the first air port 110 to the second air port 120, that is, under the action of the wind wheel 200, the air enters the first chamber 130 through the first air port 110, then flows to the second chamber 140 through the flow port 150, and is discharged from the heater 10 through the second air port 120. When the airflow flows through the first infrared heating element 300, it helps to diffuse the heat reflected by the first infrared heating element 300, so as to diffuse the hot air out of the heater 10 through the second air port 120.

[0224] This arrangement helps to diffuse heat and can increase the heat dissipation range of the heater 10. And because the heat reflected by the first infrared heating element 300 can be diffused under the action of the wind wheel 200, it can avoid the occurrence of heat concentration, can meet the use requirements of heat without burning sensation and a large heat range, improve the heating effect of the heater 10, and help improve the use performance and market competitiveness of the heater 10.

[0225] In addition, since the wind wheel 200 and the first infrared heating element 300 are located in different chambers, specifically, the wind wheel 200 is arranged in the first chamber 130, and the first infrared heating element 300 is arranged in the second chamber 140. Therefore, the cavity walls of the first chamber 130 and the second chamber 140 can play a role in heat insulation. In this way, the heat transferred from the second chamber 140 to the wind wheel 200 can be reduced, and the temperature in the first chamber 130 can be reduced. In this way, the damage to the wind wheel 200 can be reduced, which is conducive to extending the service life of the wind wheel 200. At the same time, this setting can reduce the situation where part of the heat is discharged through the first air outlet due to the radiation of the heat at the first infrared heating element 300 to the wind wheel 200, which is conducive to the directional radiation of heat and provides effective and reliable structural support for improving the working efficiency of the heater 10.

[0226] like Figure 6 As shown, a heater 10 according to some other embodiments of the present application includes: a shell 160, the shell 160 is provided with a first air outlet 110 and a second air outlet 120; a reflector 170, which is arranged in the shell 160, and a front surface 175 of the reflector is provided with a flow port 150 and at least two reflection grooves 172, the flow port 150 is connected to the first air outlet 110 and the second air outlet 120, a part of at least two reflection grooves 172 is located on one side of the flow port 150, and another part of at least two reflection grooves 172 is located on the other side of the flow port 150; a wind wheel 200, which is arranged in the shell 160 The wind wheel 200 is located on the back side 176 of the reflecting plate, and the wind wheel 200 has an outlet portion 210; the first infrared heating element 300 is located on the front side 175 of the reflecting plate, and the flow port 150 is located between the outlet portion 210 and the first infrared heating element 300; a plurality of second infrared heating elements 400, and at least one second infrared heating element 400 is provided in each reflecting groove 172; wherein the wind wheel 200 works to drive the external air flow to enter the housing 160 from the first air port 110, flow to the front side 175 of the reflecting plate through the flow port 150, and then flow out of the housing 160 through the second air port 120.

[0227] A heater 10 provided in the present application includes a housing 160 , a reflection plate 170 , a wind wheel 200 , a first infrared heating element 300 and a plurality of second infrared heating elements 400 .

[0228] The reflection plate 170 , the wind wheel 200 , the first infrared heating element 300 and the plurality of second infrared heating elements 400 are all disposed in the housing 160 .

[0229] The housing 160 is provided with a first air port 110 and a second air port 120 , and the reflector 170 is provided with a flow port 150 . The flow port 150 connects the first air port 110 and the second air port 120 .

[0230] The first infrared heating element 300 and the second infrared heating element 400 can both emit infrared radiation energy when working. The infrared radiation energy has a longer wavelength and can directly act on the surface of an object to be converted into heat energy to increase the surface temperature of the object. The infrared radiation can be reflected by the reflective plate 170 and radiated out of the heater 10 through the second air outlet 120.

[0231] When the wind wheel 200 is working, it can guide the air from the first air outlet 110 to the second air outlet 120. That is, the air enters the shell 160 through the first air outlet 110 under the action of the wind wheel 200, and then flows to the front side 175 of the reflection plate through the flow port 150, and is discharged from the heater 10 through the second air outlet 120 under the reflection action of the reflection plate 170.

[0232] When the airflow passes through the first infrared heating element 300 , it helps to diffuse the heat reflected by the first infrared heating element 300 , so as to diffuse the hot air out of the heater 10 through the second air outlet 120 .

[0233] The airflow flows through the flow port 150 to the front side 175 of the reflective plate. The reflective groove 172 has the function of reflecting heat, so that the heat at the second infrared heating element 400 can be effectively diffused out of the heater 10 through the second air port 120 under the action of the airflow.

[0234] It is understandable that by providing the first infrared heating element 300 and the second infrared heating element 400 , the number of heating elements for generating heat is increased, which can increase the heat generated by the heater 10 when it is working, which is beneficial to improving the working efficiency of the heater 10 .

[0235] This arrangement helps to diffuse heat and can increase the heat dissipation range of the heater 10. And because the heat reflected by the first infrared heating element 300 and the second infrared heating element 400 can diffuse under the action of the wind wheel 200, it can avoid the occurrence of heat concentration, can meet the use requirements of heat without burning sensation and a large heat range, improve the heating effect of the heater 10, and help improve the use performance and market competitiveness of the heater 10.

[0236] In addition, the flow port 150 is located between the outlet portion 210 of the wind wheel 200 and the first infrared heating element 300, and the flow port 150 is located between the plurality of second infrared heating elements 400. In this way, the effectiveness of the airflow flowing to the reflector 170 through the flow port 150 can be ensured, and the amount of heat at the front side 175 of the reflector flowing to the back side 176 of the reflector through the flow port 150 can be reduced. Reliable structural support is provided to ensure the working efficiency of the heater 10.

[0237] It can be understood that the reflective plate 170 has the function of reflecting heat, so that the heat can be effectively diffused out of the heater 10 through the second air outlet 120 under the action of the air flow.

[0238] At the same time, since the wind wheel 200, the first infrared heating element 300 and the second infrared heating element 400 are located on different sides of the reflective plate 170, specifically, the wind wheel 200 is located on the back side 176 of the reflective plate, and the first infrared heating element 300 and the second infrared heating element 400 are both located on the front side 175 of the reflective plate. Therefore, the reflective plate 170 can play a role in heat insulation. In this way, the heat transferred from the first infrared heating element 300 and the second infrared heating element 400 to the wind wheel 200 can be reduced, and the temperature at the wind wheel 200 can be reduced. In this way, the damage to the wind wheel 200 can be reduced, which is conducive to extending the service life of the wind wheel 200. At the same time, this setting can reduce the situation where part of the heat is discharged through the first air outlet 110 due to the radiation of the heat at the first infrared heating element 300 and the second infrared heating element 400 to the wind wheel 200, which is conducive to the directional radiation of heat and provides effective and reliable structural support for improving the working efficiency of the heater 10.

[0239] In some embodiments, optionally, the wind wheel 200 is a cross-flow wind wheel 200, and the outlet portion 210 of the cross-flow wind wheel 200, the first infrared heating element 300, the second infrared heating element 400 and the flow port 150 of the reflective plate 170 all extend along the height direction of the shell 160; the dimension of the shell 160 in the height direction is recorded as L1, and the dimension of the shell 160 in the direction perpendicular to the height direction is recorded as L2, and L1 is greater than L2.

[0240] In this embodiment, the matching structure of the housing 160, the wind wheel 200, the reflection plate 170, the first infrared heating element 300 and the second infrared heating element 400 is further defined.

[0241] The height direction is either the direction from the bottom to the top of the housing 160 or the direction from the top to the bottom of the housing 160. The height dimension of the housing 160 is L1, and the dimension of the housing 160 perpendicular to the height direction is L2, and L1 is greater than L2.

[0242] That is, the height of the housing 160 is greater than the width of the housing 160 in the first direction, and the height of the housing 160 is greater than the width of the housing 160 in the second direction. Any two of the first direction, the second direction and the height direction are perpendicular to each other.

[0243] The outlet portion 210 of the crossflow wind wheel 200, the first infrared heating element 300, the second infrared heating element 400 and the flow opening 150 of the reflective plate 170 all extend in the height direction of the housing 160, that is, the outlet portion 210 of the crossflow wind wheel 200 extends in the height direction of the housing 160, the first infrared heating element 300 extends in the height direction of the housing 160, the second infrared heating element 400 extends in the height direction of the housing 160, and the flow opening 150 of the reflective plate 170 extends in the height direction of the housing 160. It can be seen that the outlet portion 210 of the crossflow wind wheel 200, the first infrared heating element 300, the second infrared heating element 400 and the flow opening 150 of the reflective plate 170 all extend in the direction of the larger size of the housing 160. Optionally, the outlet portion 210 of the wind wheel 200, the first infrared heating element 300, the second infrared heating element 400 and the flow opening 150 of the reflective plate 170 are all arranged in the length direction of the wind wheel 200. That is, the wind wheel 200, the first infrared heating element 300, the second infrared heating element 400 and the reflection plate 170 are all placed in the vertical direction.

[0244] In this way, it is beneficial to increase the volume of the first infrared heating element 300 and the second infrared heating element 400, and to increase the heat generated per unit time. In addition, this arrangement enables different positions of the first infrared heating element 300 and the second infrared heating element 400 to effectively contact the airflow flowing out of the outlet portion 210 of the wind wheel 200, which is beneficial to heat radiation.
