Due to the limitation of spatial structure, the widths of different areas in the drying air duct of the clothes processing equipment in the radial direction of the drum are not completely consistent, which leads to uneven flow rate of the fluid flowing to the air inlet side of the heater in the air duct, which in turn leads to uneven temperature distribution on the air outlet side of the heater, affecting the drying effect of the clothes processing equipment.

Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as those generally understood by those of ordinary skill in the art. Some technical terms appearing in the embodiments of the present application are explained below.

[0034] In order to make the technical solutions and advantages of the present application more clear, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0035] like Figures 1 to 3 As shown, an embodiment of the present application provides a heater 1 , which includes a heating element 11 and a heat dissipation portion 12 .

[0036] Exemplarily, the heater 1 is a PTC electric heater 1 , the heating element 11 is a heating ceramic component, and the heater 1 is applied to a clothing processing device 100 such as a dryer and a washing machine.

[0037] like Figure 1As shown, the heat dissipation part 12 has a ventilation direction, and the heat dissipation part 12 includes a first containing box 121 and a second containing box 122. The first containing box 121 and the second containing box 122 both have inner cavities, and flow channels are respectively constructed in the inner cavities of the first containing box 121 and the second containing box 122. The first containing box 121 and the second containing box 122 are respectively arranged on both sides of the thickness direction of the heating element 11, and a first heat dissipation member 131 is arranged in the first containing box 121, and a second heat dissipation member 132 is arranged in the second containing box 122, wherein the ratio of the cross-sectional area of ​​the first heat dissipation member 131 to the inner cavity of the first containing box 121 in the ventilation direction is smaller than the ratio of the cross-sectional area of ​​the second heat dissipation member 132 to the inner cavity of the second containing box 122 in the ventilation direction.

[0038] It should be noted that the above-mentioned “cross-sectional area in the ventilation direction” is the area of ​​the cross section obtained by cutting with a plane perpendicular to the ventilation direction, the above-mentioned “ratio of the cross-sectional areas of the first heat sink 131 and the inner cavity of the first containing box 121 in the ventilation direction” means the ratio of the cross-sectional area of ​​the first heat sink 131 in the ventilation direction to the cross-sectional area of ​​the inner cavity of the first containing box 121 in the ventilation direction, and the above-mentioned “ratio of the cross-sectional area of ​​the second heat sink 132 and the inner cavity of the second containing box 122 in the ventilation direction” means the ratio of the cross-sectional area of ​​the second heat sink 132 in the ventilation direction to the cross-sectional area of ​​the inner cavity of the second containing box 122 in the ventilation direction.

[0039] The heating element 11 is used to generate heat. The first heat sink 131 and the second heat sink 132 are respectively thermally connected to the heating element 11. The first heat sink 131 and the second heat sink 132 are used to increase the heat dissipation area, improve the heat exchange efficiency, and transfer the heat to the surrounding environment faster.

[0040] Exemplarily, the volume of the first containing box 121 is the same as the volume of the second containing box 122. Specifically, the first containing box 121 and the second containing box 122 are both rectangular shells with openings on both sides, and the two openings spaced apart form an air inlet and an air outlet, respectively. The first containing box 121 is formed with a first flow channel 121a, and the second containing box 122 is formed with a second flow channel 122a. The air inlet and the air outlet of the first flow channel 121a are distributed along the first direction X, and the air inlet and the air outlet of the second flow channel 122a are also distributed along the first direction X, that is, the ventilation direction of the heat dissipation portion 12 is parallel to the first direction X. The thickness direction of the heating element 11 is parallel to the second direction Y, wherein the first direction X is perpendicular to the second direction Y.

[0041] Exemplarily, the cross-sectional area of ​​the first heat dissipation member 131 is different from the cross-sectional area of ​​the second heat dissipation member 132 by arranging the first heat dissipation member 131 and the second heat dissipation member 132 to have different shapes, sizes, thicknesses, quantities, bending angles, etc.

[0042] Since the ratio of the cross-sectional area of ​​the first heat sink 131 to the inner cavity of the first containing box 121 in the ventilation direction is smaller than the ratio of the cross-sectional area of ​​the second heat sink 132 to the inner cavity of the second containing box 122 in the ventilation direction, the density of the first heat sink 131 in the first containing box 121 is smaller than the density of the second heat sink 132 in the second containing box 122. Therefore, when the fluid flow rate at the air inlet of the second flow channel 122a is greater than the fluid flow rate at the air inlet of the first flow channel 121a, the second heat sink 132 can increase the fluid flow resistance, thereby reducing the fluid flow rate in the second flow channel 122a, so that the fluid flow rates in the first flow channel 121a and the second flow channel 122a tend to be consistent, and then the fluid flow rate at the air outlet of the second flow channel 122a and the fluid flow rate at the air outlet of the first flow channel 121a tend to be consistent.

[0043] The heater 1 provided in the embodiment of the present application is configured such that the ratio of the cross-sectional area of ​​the first heat sink 131 to the inner cavity of the first containing box 121 in the ventilation direction is smaller than the ratio of the cross-sectional area of ​​the second heat sink 132 to the inner cavity of the second containing box 122 in the ventilation direction, so that the fluid flow resistance in the flow channel of the second containing box 122 is greater than the fluid flow resistance in the flow channel of the first containing box 121. When the fluid flow velocities on the air inlet side of the heater 1 are different, the second heat sink 132 corresponds to the high flow velocity area, and the first heat sink 131 corresponds to the low flow velocity area, so that the fluid flow velocity in the flow channel of the second containing box 122 can be appropriately reduced, so that the fluid flow velocity on the air outlet side of the flow channel of the second containing box 122 is consistent with the fluid flow velocity on the air outlet side of the flow channel of the first containing box 121, thereby improving the uniformity of the fluid flow velocity and the temperature uniformity on the air outlet side of the heater 1, which is beneficial to improving the drying effect of the clothing processing device 100.

[0044] In a further embodiment, the cross-sectional shapes of the first heat dissipation element 131 and the second heat dissipation element 132 in the ventilation direction are both wavy.

[0045] like Figures 1 to 3 As shown, the first heat dissipation member 131 and the second heat dissipation member 132 extend and undulate continuously and regularly along a third direction Z, wherein the third direction Z is perpendicular to the first direction X and the second direction Y, respectively.

[0046] In this embodiment, by setting the cross-sectional shapes of the first heat sink 131 and the second heat sink 132 in the ventilation direction to be wavy, the heat dissipation area is increased, the heat dissipation efficiency is improved, and thus the heating effect of the heater 1 on the fluid in the flow channel is improved.

[0047] In a specific embodiment, the wavelength of the cross section of the first heat dissipation element 131 in the ventilation direction is greater than the wavelength of the cross section of the second heat dissipation element 132 in the ventilation direction.

[0048] like Figure 1As shown, in the waveform of the cross section of the first heat sink 131 and the second heat sink 132, the wavelength is the distance between two adjacent peaks or two adjacent troughs in the third direction Z, the wavelength of the cross-sectional waveform of the first heat sink 131 is A1, and the wavelength of the cross-sectional waveform of the second heat sink 132 is A2, satisfying A1>A2.

[0049] It is understandable that the number, waveform amplitude and other parameters of the first heat sink 131 and the second heat sink 132 are the same or different, as long as the cross-sectional area of ​​the first heat sink 131 is smaller than the cross-sectional area of ​​the second heat sink 132 .

[0050] In this embodiment, by setting the wavelength of the cross-section of the first heat sink 131 to be larger than the wavelength of the cross-section of the second heat sink 132, the density of the first heat sink 131 within a unit volume is less than the density of the second heat sink 132, thereby increasing the fluid flow resistance in the second flow channel 122a, which is beneficial for making the fluid flow rate at the outlet of the second flow channel 122a and the fluid flow rate at the outlet of the first flow channel 121a tend to be consistent when the fluid flow rate at the air inlet of the second flow channel 122a is greater than the fluid flow rate at the air inlet of the first flow channel 121a.

[0051] In a specific embodiment, the amplitude of the cross section of the first heat dissipation element 131 in the ventilation direction is smaller than the amplitude of the cross section of the second heat dissipation element 132 in the ventilation direction.

[0052] like Figure 3 As shown, in the waveform of the cross section of the first heat sink 131 and the second heat sink 132, the amplitude is the distance between the crest and the adjacent trough in the second direction Y, the amplitude of the cross-sectional waveform of the first heat sink 131 is B1, and the wavelength of the cross-sectional waveform of the second heat sink 132 is B2, satisfying B1<B2.

[0053] It is understandable that the number, waveform wavelength and other parameters of the first heat sink 131 and the second heat sink 132 are the same or different, as long as the cross-sectional area of ​​the first heat sink 131 is smaller than the cross-sectional area of ​​the second heat sink 132.

[0054] In this embodiment, by setting the amplitude of the cross-section of the first heat sink 131 to be smaller than the amplitude of the cross-section of the second heat sink 132, the density of the first heat sink 131 in unit volume is made smaller than the density of the second heat sink 132, thereby increasing the fluid flow resistance in the second flow channel 122a, which is beneficial for making the fluid flow rate at the outlet of the second flow channel 122a and the fluid flow rate at the outlet of the first flow channel 121a tend to be consistent when the fluid flow rate at the air inlet of the second flow channel 122a is greater than the fluid flow rate at the air inlet of the first flow channel 121a.

[0055] In a specific embodiment, there are multiple second heat dissipation elements 132 , which are spaced apart along the thickness direction of the heating element 11 , and the number of first heat dissipation elements 131 is less than the number of second heat dissipation elements 132 .

[0056] There are one or more first heat dissipation members 131. Exemplarily, there are multiple first heat dissipation members 131 and multiple second heat dissipation members 132. Multiple first heat dissipation members 131 are distributed along the second direction Y at intervals, and multiple second heat dissipation members 132 are distributed along the second direction Y at intervals.

[0057] like Figure 1 and Figure 2 As shown, there are two first heat sinks 131 and four second heat sinks 132. The cross-sectional area of ​​each first heat sink 131 may be the same as the cross-sectional area of ​​each second heat sink 132, or may be different from the cross-sectional area of ​​each second heat sink 132, as long as the ratio of the sum of the cross-sectional areas of the plurality of first heat sinks 131 to the cross-sectional area of ​​the inner cavity of the first containing box 121 is smaller than the ratio of the sum of the cross-sectional areas of the plurality of second heat sinks 132 to the cross-sectional area of ​​the inner cavity of the second containing box 122.

[0058] In this embodiment, by setting the number of first heat sinks 131 to be smaller than the number of second heat sinks 132, the fluid flow resistance in the second flow channel 122a is increased, which is beneficial for making the fluid flow rate at the outlet of the second flow channel 122a and the fluid flow rate at the outlet of the first flow channel 121a tend to be consistent when the fluid flow rate at the air inlet of the second flow channel 122a is greater than the fluid flow rate at the air inlet of the first flow channel 121a.

[0059] Optionally, both the first containing box 121 and the second containing box 122 are provided with a transverse partition to divide the inner cavity into multiple layers, for example Figure 1 As shown, the first containing box 121 and the second containing box 122 are respectively provided with a transverse partition, each layer of the first containing box 121 contains a first heat dissipating element 131 , and each layer of the second containing box 122 contains two second heat dissipating elements 132 .

[0060] In a further embodiment, the crests of at least one second heat dissipation element 132 are inserted between adjacent troughs of adjacent second heat dissipation elements 132 .

[0061] like Figure 1 As shown, there are four second heat dissipation elements 132 , and the wave crests of two second heat dissipation elements 132 are inserted into the adjacent wave valleys of the second heat dissipation element 132 above.

[0062] Through this arrangement, while saving the space occupied by the second heat sink 132, the density of the second heat sink 132 in the second containing box 122 is improved, and the fluid flow resistance in the second flow channel 122a is increased, which is beneficial for making the fluid flow rate at the outlet of the second flow channel 122a and the fluid flow rate at the outlet of the first flow channel 121a tend to be consistent when the fluid flow rate at the air inlet of the second flow channel 122a is greater than the fluid flow rate at the air inlet of the first flow channel 121a.

[0063] like Figure 4 As shown, the embodiment of the present application also provides a drying component 10, which includes a shell 101, a fan 102 and a heater 1 provided in any of the above embodiments, the shell 101 includes a first mounting portion 101a and a second mounting portion 101b that are connected, the fan 102 is accommodated in the first mounting portion 101a, and the heater 1 is accommodated in the second mounting portion 101b.

[0064] Specifically, an air duct is constructed in the housing 101, such as Figure 4 As shown by the arrows in , driven by the fan 102, the gas flows from the air inlet of the air duct to the heater 1, and then flows out from the air outlet of the air duct to heat the gas.

[0065] In a further embodiment, Figure 5 As shown, the first mounting portion 101a and the second mounting portion 101b are arranged along the first direction X, the first side of the second mounting portion 101b in the second direction Y is protruding relative to the first mounting portion 101a, and the second heat dissipation member 132 of the heater 1 is located on the first side of the second mounting portion 101b in the second direction Y, wherein the first direction X is perpendicular to the second direction Y.

[0066] like Figure 5 As shown, the first side of the second mounting portion 101b in the second direction Y is the lower side of the second mounting portion 101b, the second side of the second mounting portion 101b in the second direction Y is the upper side of the second mounting portion 101b, the lower side of the second mounting portion 101b protrudes downward relative to the lower side of the first mounting portion 101a, the upper side of the second mounting portion 101b is flush with the upper side of the first mounting portion 101a, the first containing box 121 is located above the second containing box 122, the first heat dissipation member 131 is closer to the upper side of the second mounting portion 101b, and the second heat dissipation member 132 is closer to the lower side of the second mounting portion 101b.

[0067] Due to the dimensional change between the lower side of the first mounting portion 101a and the lower side of the second mounting portion 101b, a flared structure is formed. Therefore, when the gas in the air duct flows from the fan 102 to the heater 1 along the first direction X, the fluid flow rate at the lower side of the air inlet of the second mounting portion 101b is greater than the fluid flow rate at the upper side of the air inlet of the second mounting portion 101b. By arranging the second heat dissipation member 132 of the heater 1 at the lower side of the second mounting portion 101b, the fluid flow resistance in the second flow channel 122a is increased, so that the fluid flow rate at the outlet of the second flow channel 122a and the fluid flow rate at the outlet of the first flow channel 121a tend to be consistent, thereby improving the uniformity of the fluid flow rate and the temperature uniformity on the air outlet side of the heater 1, which is beneficial to improving the drying effect of the clothing processing device 100.

[0068] The embodiment of the present application further provides a clothing processing device 100, comprising the drying component 10 provided in the above embodiment.

[0069] Furthermore, if Figure 6 As shown, the laundry processing device 100 further includes a drum 1001 and a door seal assembly 1002, wherein the door seal assembly 1002 is mounted at one end of the drum 1001 in a first direction X, and the drying assembly 10 is mounted at one side of the drum 1001 in a second direction Y, and the second mounting portion 101b of the drying assembly 10 is connected to the door seal assembly 1002, wherein the first direction is perpendicular to the second direction, and the second direction is parallel to the horizontal direction. It can be understood that the above-mentioned "horizontal direction" is a direction parallel to the horizon, that is, the drying assembly 10 is mounted at one side of the drum 1001 in the horizontal direction.

[0070] like Figure 6 As shown, the drying assembly 10 is located on the side of the drum 1001. Driven by the fan 102, the air flows along Figure 6 The air enters the air duct of the drying component 10 in the direction of the arrow shown, flows through the heater 1 and then enters the door sealing component 1002, and then enters the drum 1001 from the door sealing component 1002 to dry the clothes in the drum 1001.

[0071] Exemplarily, the clothes processing device 100 is a drying machine, a washing machine, a shoe washing machine, a washing-drying machine, etc.
