Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of clothes drying equipment, in particular to a clothes dryer. BACKGROUND

[0002] The clothes dryer refers to a cleaning household appliance which uses electric heating to evaporate and dry the moisture in the washed clothes. The clothes dryer is provided with a convection mode to accelerate the drying efficiency of the clothes while being heated by electricity. Considering the waterproof requirement of the circuit board, the air inlet of the clothes dryer is usually arranged at the bottom of the clothes dryer instead of the side surface where the display panel is arranged. Therefore, the air inlet area of the bottom of the clothes dryer is limited, which results in that the drying efficiency of the clothes dryer cannot be further improved. SUMMARY

[0003] In view of the above problems, the present application is proposed to provide a clothes dryer which overcomes the above problems or at least partially solves the above problems.

[0004] The present application provides a clothes dryer, which comprises:

[0005] a first shell;

[0006] a connecting base mounted on the first shell, the connecting base being provided with an air inlet cavity communicated with the first shell, and the connecting base being provided with an air inlet hole communicated with the air inlet cavity, wherein an accommodation cavity is arranged on the end of the connecting base away from the first shell;

[0007] a circuit board mounted in the accommodation cavity, and the connecting base being provided with a heat dissipation hole communicated with the accommodation cavity and the air inlet cavity;

[0008] a display panel arranged on the end surface of the circuit board away from the accommodation cavity to seal the accommodation cavity.

[0009] An optional solution is that the connecting base is further provided with a water baffle, the water baffle is arranged in the air inlet cavity, and surrounds the heat dissipation hole.

[0010] In the summary, the water baffle is used to shield the water entering the air inlet cavity from the air inlet hole, so as to prevent the water in the water inlet cavity from entering the accommodation cavity through the heat dissipation hole. Therefore, the water baffle can be arranged in the air inlet cavity and surround the heat dissipation hole. Thus, the water entering the air inlet cavity can be guided by the water baffle. The water baffle can surround the heat dissipation hole.

[0011] Optionally, a plurality of limiting ribs are arranged in the accommodating cavity, and the cross-sectional shape of the limiting ribs is adapted to the cross-sectional shape of the circuit board, so that the circuit board is mounted on the limiting ribs.

[0012] In the present application, the limiting ribs increase the distance between the heat dissipation hole and the circuit board, thereby improving the waterproof performance of the circuit board. A small amount of water entering the water inlet cavity from the water inlet hole will not affect the electrical performance of the circuit board even after entering the accommodating cavity from the heat dissipation hole. Under the influence of a certain wind speed generated during the operation of the clothes dryer, the water entering the accommodating cavity can be quickly evaporated and dried. Therefore, the arrangement of the limiting ribs can quickly determine the assembly position of the circuit board while ensuring the waterproof requirement of the circuit board, thereby improving the assembly convenience of the circuit board.

[0013] Optionally, a wiring hole is formed in the connecting base and communicates the accommodating cavity and the air inlet cavity, and the wiring hole is formed at the lowest height position in the accommodating cavity.

[0014] In the present application, the wiring hole is used for the wires of the circuit board to pass through, facilitating the installation of the circuit board in the accommodating cavity. The wires of the circuit board enter the air inlet cavity through the wiring hole and enter the mounting cavity through the air inlet cavity, so as to be electrically connected with each electrical component in the clothes dryer. When a small amount of water enters the accommodating cavity from the heat dissipation hole, it can also flow to the lowest height position of the accommodating cavity. Therefore, by arranging the wiring hole at the lowest height position of the accommodating cavity, the water in the accommodating cavity can also be guided through the wiring hole, thereby further improving the waterproof performance of the circuit board.

[0015] Optionally, the display panel is distanced from the end surface of the circuit board and is embedded in the accommodating cavity.

[0016] In the present application, the connecting base at the opening of the accommodating cavity can shield the water flow, thereby avoiding the water flowing from the opening of the accommodating cavity to the end of the display panel close to the circuit board and affecting the electrical performance of the circuit board. Therefore, the waterproof performance of the circuit board can be further improved, and the long-term operation stability of the clothes dryer can be ensured.

[0017] Optionally, the connecting base is a horizontally placed circular truncated cone structure, and the clothes dryer further comprises an air duct assembly arranged in the first shell and coaxially arranged with the connecting base.

[0018] In the present application, the connecting base is a circular table structure, which can improve the structural strength of the connecting base and provide support for the circuit board and the display panel. The air duct assembly is coaxially arranged with the connecting base, that is, the central axis of the air duct assembly coincides with the central axis of the connecting base. Thus, when the air duct assembly is working, external air can quickly enter the mounting cavity from the air inlet hole, thereby improving the air intake of the clothes dryer and improving the drying efficiency.

[0019] In an optional solution, the air inlet hole is formed on the side surface of the connecting base. When the number of air inlet holes is multiple, the air inlet holes are uniformly distributed around the side surface of the connecting base.

[0020] In the present application, when multiple air inlet holes are uniformly distributed around the side surface of the connecting base, air at each angle can enter the air duct assembly, thereby further increasing the air intake.

[0021] In an optional solution, the accommodating cavity is further provided with a first positioning rib, and the circuit board is provided with a first positioning hole matched with the shape of the first positioning rib, so as to position the circuit board by the first positioning rib.

[0022] In the present application, the circuit board can be accurately positioned by the cooperation between the first positioning rib and the first positioning hole. Therefore, during the assembly of the circuit board, the first positioning rib and the first positioning hole can be aligned in advance, and then the circuit board is placed on the limiting rib, thereby completing the assembly of the circuit board.

[0023] In an optional solution, the display panel is provided with a buckle near the end surface of the circuit board, and the accommodating cavity is provided with a clamping groove corresponding to the assembly position of the display panel. The buckle and the clamping groove are matched to clamp the display panel on the connecting base.

[0024] In the present application, the accommodating cavity is provided with a clamping groove corresponding to the assembly position of the display panel, and the number of clamping grooves is consistent with the number of buckles. Therefore, after the first positioning rib and the first positioning hole are aligned and the circuit board is placed on the limiting rib to complete the assembly of the circuit board, the display panel can be clamped on the connecting base. Through the clamping cooperation of the buckle and the clamping groove, the assembly convenience of the display panel can be improved, the installation is convenient, and the assembly cost of other fasteners can be reduced.

[0025] An optional solution is that the display panel is provided with a positioning rib near the end face of the circuit board, and the accommodating cavity is provided with a second positioning rib, the positioning rib and the second positioning rib cooperate to limit the position of the display panel in the accommodating cavity.

[0026] In the content of the application, the positioning rib and the second positioning rib can be matched by a gap to limit the position of the display panel in the accommodating cavity, so that the display panel can be quickly positioned by the second positioning rib after the assembly of the circuit board is completed.

[0027] An optional solution is that the display panel is provided with a positioning rib near the end face of the circuit board, and the accommodating cavity is provided with a second positioning rib, the positioning rib and the second positioning rib cooperate to limit the position of the display panel in the accommodating cavity.

[0028] In the content of the application, the distance between the display panel and the circuit board can be controlled by the length of the positioning column, so that the touch feeling of the display panel on the control button on the circuit board can be ensured, and the functional button on the display panel and the circuit button of the circuit board can be kept consistent.

[0029] Compared with the prior art, the application comprises a first shell, a connecting base, a circuit board and a display panel, the connecting base is installed on the first shell, the connecting base is provided with an air inlet cavity communicated with the first shell and an air inlet hole communicated with the air inlet cavity, and an accommodating cavity is formed in the end of the connecting base away from the first shell. The circuit board is installed in the accommodating cavity, and the connecting base is provided with a heat dissipation hole communicated with the accommodating cavity and the air inlet cavity. The display panel is arranged on the end face of the circuit board away from the accommodating cavity to seal the accommodating cavity. Therefore, based on the requirement of opening holes for installing the circuit board, the connecting base with an air inlet channel is added, the circuit board is installed on the connecting base, and the connecting base is fixed on the first shell, so that the air inlet area is increased and the drying efficiency of the clothes dryer is improved based on the waterproof performance of the circuit board.

DETAILED DESCRIPTION

[0043] Exemplary embodiments of the present application will be described in greater detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it is understood that the present application can be embodied in various forms without being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.

[0044] A clothes dryer refers to a cleaning type home appliance that uses electric heating to instantly evaporate and dry moisture in washed clothes. It also sets a convection method while being heated by electricity to accelerate the drying efficiency of the clothes. In consideration of the waterproofing requirement of the circuit board 3, the clothes dryer in the related art is generally configured to set an air inlet of the clothes dryer at a bottom of the clothes dryer, rather than at a side where a display panel 4 is installed. Thus, the air inlet area of the bottom of the clothes dryer is limited, which results in the drying efficiency of the clothes dryer not being further improved.

[0045] A clothes dryer according to the embodiments of the present application can include a first housing 1, a connection base 2 installed on the first housing 1, a circuit board 3, and a display panel 4. The connection base 2 is provided with an air inlet cavity 201 communicating with the first housing 1, and an air inlet hole 202 communicating with the air inlet cavity 201. An accommodation cavity 203 is formed at an end of the connection base 2 away from the first housing 1. The circuit board 3 is installed in the accommodation cavity 203, and the connection base 2 is provided with a heat dissipation hole 204 communicating the accommodation cavity 203 and the air inlet cavity 201. The display panel 4 is disposed on an end surface of the circuit board 3 away from the accommodation cavity 203 to seal the accommodation cavity 203. Thus, based on the need for a mounting hole for the circuit board 3, the connection base 2 having an air inlet passage is added, the circuit board 3 is installed on the connection base 2, and the connection base 2 is fixed to the first housing 1. Thus, based on the waterproof performance of the circuit board 3, the air inlet area is increased, and the drying efficiency of the clothes dryer is improved.

[0046] Referring to Figures 1-9 , the present application provides a clothes dryer, which can include a first housing 1, a connection base 2, a circuit board 3, and a display panel 4.

[0047] The connecting base 2 is installed on the first shell 1, the connecting base 2 is provided with an air inlet cavity 201 communicated with the first shell 1, and is provided with an air inlet hole 202 communicated with the air inlet cavity 201, and the end of the connecting base 2 away from the first shell 1 is provided with a containing cavity 203. The circuit board 3 is installed in the containing cavity 203, and the connecting base 2 is provided with a heat dissipation hole 204 communicated with the containing cavity 203 and the air inlet cavity 201. The display panel 4 is arranged on the end surface of the circuit board 3 away from the containing cavity 203, so as to seal the containing cavity 203.

[0048] In the embodiment of the application, the connecting base 2 and the first shell 1 can be fixed through a clamping structure. The connecting base 2 is provided with an air inlet cavity 201 communicated with the first shell 1. That is, the first shell 1 is provided with a mounting cavity 101, and the mounting cavity 101 is in air communication with the air inlet cavity 201. The connecting base 2 is further provided with an air inlet hole 202 communicated with the air inlet cavity 201. Under the action of air pressure, external air enters the air inlet cavity 201 from the air inlet hole 202 and enters the mounting cavity 101 through the air inlet cavity 201.

[0049] The end of the connecting base 2 away from the first shell 1 is provided with a containing cavity 203, the opening of the containing cavity 203 can be horizontally arranged and faces away from the end of the first shell 1. It is used to provide the mounting area of the circuit board 3 and the display panel 4. The circuit board 3 is installed in the containing cavity 203, and the connecting base 2 is provided with a heat dissipation hole 204 communicated with the containing cavity 203 and the air inlet cavity 201. The air inlet cavity 201 is arranged so that the circuit board 3 is spaced from the end of the connecting base 2 close to the first shell 1, so as to ensure the smoothness of air inlet from the air inlet hole 202.

[0050] The heat dissipation hole 204 is arranged on the end surface of the circuit board 3 away from the display panel 4, so as to dissipate the heat generated by the circuit board 3 during operation to the air inlet cavity 201 through the heat dissipation hole 204. The display panel 4 is arranged on the end surface of the circuit board 3 away from the containing cavity 203, so as to seal the containing cavity 203. Thus, on the basis of the mounting hole for the circuit board 3, the connecting base 2 with complete air inlet channel is added, the circuit board 3 is installed on the connecting base 2, and the connecting base 2 is fixed on the first shell 1, so that the waterproof performance of the circuit board 3 can be met, the air inlet area can be increased, and the drying efficiency of the clothes dryer can be improved.

[0051] In the assembling process of the clothes dryer, the connecting base 2 can be first clamped to the first shell 1, then the circuit board 3 is placed into the accommodating cavity 203, and finally the display panel 4 is assembled.

[0052] In summary, the embodiment of the present application discloses a clothes dryer, which can include a first shell 1, a connecting base 2, a circuit board 3 and a display panel 4. The connecting base 2 is installed on the first shell 1, and the connecting base 2 is provided with an air inlet cavity 201 communicated with the first shell 1, and an air inlet hole 202 communicated with the air inlet cavity 201. The end of the connecting base 2 away from the first shell 1 is provided with an accommodating cavity 203. The circuit board 3 is installed in the accommodating cavity 203, and the connecting base 2 is provided with a heat dissipation hole 204 communicating the accommodating cavity 203 and the air inlet cavity 201. The display panel 4 is arranged on the end surface of the circuit board 3 away from the accommodating cavity 203 to seal the accommodating cavity 203. Thus, based on the mounting hole for the circuit board 3, the connecting base 2 with an air inlet channel is added, the circuit board 3 is installed on the connecting base 2, and the connecting base 2 is fixed on the first shell 1, so that the air inlet area is increased and the drying efficiency of the clothes dryer is improved based on the waterproof performance of the circuit board 3.

[0053] An optional embodiment of the present application is shown in Figure 6 The connecting base 2 is further provided with a water baffle 5, which is located in the air inlet cavity 201 and surrounds the heat dissipation hole 204.

[0054] In the embodiment of the present application, the water baffle 5 is used to block the water entering the air inlet cavity 201 from the air inlet hole 202, so as to prevent the water in the water inlet cavity from entering the accommodating cavity 203 through the heat dissipation hole 204. Therefore, the water baffle 5 can be arranged in the air inlet cavity 201 and surround the heat dissipation hole 204. Thus, the water entering the air inlet cavity 201 can be guided by the water baffle 5. The water baffle 5 can surround the heat dissipation hole 204.

[0055] In an example, the cross-sectional shape of the heat dissipation holes 204 can be circular, rectangular, or the like, and those skilled in the art can determine the cross-sectional shape of the heat dissipation holes 204 according to actual design requirements, which will not be limited herein. The number of the heat dissipation holes 204 can be multiple, and the multiple heat dissipation holes 204 can be arranged in a matrix on the connecting base 2, thereby forming a heat dissipation grid, which is beneficial to the rapid heat dissipation of the circuit board 3 during work. In the case of multiple heat dissipation holes 204, the water baffle 5 is arranged around all the heat dissipation holes 204. Thus, in some embodiments, the water baffle 5 can be completely arranged around the heat dissipation holes 204, that is, the cross-sectional shape of the water baffle 5 can be a closed ring.

[0056] In other embodiments, the cross-sectional shape of the water baffle 5 can also be a ring with an opening. The opening of the water baffle 5 can be arranged at the lowest position of the water baffle 5, thereby ensuring that the arrangement height of any one heat dissipation hole 204 is greater than the opening height of the water baffle 5, avoiding the accumulation of water flow through the heat dissipation hole 204 into the accommodating cavity 203.

[0057] The external air enters the air inlet cavity 201 from the air inlet hole 202 and enters the mounting cavity 101 through the air inlet cavity 201. Under the action of the working air pressure of the clothes dryer, when water enters the air inlet cavity 201 from the water inlet hole, it will move to the mounting cavity 101 of the first shell 1 due to the air pressure, thereby ensuring the waterproof performance of the circuit board 3 at the position opposite to the air path. In the absence of air pressure, when water enters the air inlet cavity 201 from the water inlet hole, it will be guided by the water baffle 5 to a position lower than the heat dissipation hole 204 due to the arrangement of the water baffle 5, thereby ensuring the waterproof performance of the circuit board 3.

[0058] An optional embodiment of the application is shown in FIGS. 1 to 5, wherein the accommodating cavity 203 further comprises a water baffle 5 arranged around the heat dissipation holes 204. Figure 3 , Figure 4 and Figure 6 The cross-sectional shape of the water baffle 5 is adapted to the cross-sectional shape of the circuit board 3, so that the circuit board 3 is mounted on the limiting ribs 6.

[0059] In the embodiment of the present application, the accommodating cavity 203 is provided with a plurality of limiting ribs 6, the cross-sectional shape of the limiting ribs 6 is formed to be adapted to the cross-sectional shape of the circuit board 3. That is, the positioning of the mounting area of the circuit board 3 in the accommodating cavity 203 can be completed by limiting the shape of the plurality of limiting ribs 6. Moreover, the limiting ribs 6 increase the distance between the heat dissipation hole 204 and the circuit board 3, thereby improving the waterproof performance of the circuit board 3. A small amount of water entering the water inlet cavity from the water inlet hole will not affect the electrical performance of the circuit board 3 even after entering the accommodating cavity 203 from the heat dissipation hole 204. Under the influence of a certain wind speed generated when the clothes dryer is working, the water entering the accommodating cavity 203 can be quickly evaporated and dried. Therefore, the limiting ribs 6 can quickly determine the assembly position of the circuit board 3 while ensuring the waterproof requirement of the circuit board 3, thereby improving the assembly convenience of the circuit board 3.

[0060] In some embodiments, the limiting ribs 6 can extend from the bottom surface (the end surface close to the air inlet cavity 201) of the circuit board 3 to the side surface of the circuit board 3, and respectively contact the two surfaces of the circuit board 3. Therefore, the cross-section formed by the plurality of limiting ribs 6 is adapted to the cross-section of the circuit board 3 with a certain gap. For example, the fitting gap between a single limiting rib 6 and the circuit board 3 can be less than 0.1 mm.

[0061] An alternative embodiment of the present application is shown in Figure 3 , Figure 5 and Figure 6 The connecting base 2 is further provided with a wiring hole 205 communicating the accommodating cavity 203 and the air inlet cavity 201, wherein the lowest height position of the wiring hole 205 is provided in the accommodating cavity 203.

[0062] In the embodiment of the present application, the connecting base 2 is further provided with a wiring hole 205 communicating the accommodating cavity 203 and the water inlet cavity, wherein the wiring hole 205 is used for the wires of the circuit board 3 to pass through, facilitating the installation of the circuit board 3 in the accommodating cavity 203, and the wires of the circuit board 3 enter the air inlet cavity 201 through the wiring hole 205 and enter the mounting cavity 101 through the air inlet cavity 201, so as to be electrically connected with each electrical component in the clothes dryer.

[0063] Thus, the electrical components in the clothes dryer can be controlled by the circuit board 3. As a preferred embodiment, the wiring hole 205 is formed at the lowest position of the accommodating cavity 203. That is, when a small amount of water enters the accommodating cavity 203 from the heat dissipation hole 204, the water can also flow to the lowest position of the accommodating cavity 203 along the accommodating cavity 203. Thus, when the wiring hole 205 is arranged at the lowest position of the accommodating cavity 203, the water in the accommodating cavity 203 can also be guided through the wiring hole 205, thereby further improving the waterproof performance of the circuit board 3.

[0064] When the water baffle 5 is a closed ring, the wiring hole 205 is located outside the water baffle 5, that is, the water baffle 5 separates the wiring hole 205 and the heat dissipation hole 204 on both sides of the water baffle 5.

[0065] In summary, when the clothes dryer is drying clothes, if the clothes dryer is working, external air enters the air inlet cavity 201 from the air inlet hole 202 and enters the mounting cavity 101 through the air inlet cavity 201. When water enters the air inlet cavity 201 from the water inlet hole under the action of the working air pressure of the clothes dryer, it will move into the mounting cavity 101 of the first shell 1 due to the air pressure, thereby ensuring the waterproof performance of the circuit board 3 at the opposite position of the air path. Without the action of air pressure, when water enters the air inlet cavity 201 from the water inlet hole, the water will be guided to a position lower than the heat dissipation hole 204 due to the arrangement of the water baffle 5, thereby ensuring the waterproof performance of the circuit board 3.

[0066] Further, if a small amount of water enters the accommodating cavity 203 along the heat dissipation hole 204, the arrangement of the limiting rib 6 increases the distance between the heat dissipation hole 204 and the circuit board 3, thereby improving the waterproof performance of the circuit board 3. So that the water entering the accommodating cavity 203 will not contact the circuit board 3 and will not affect the electrical performance of the circuit board 3, and under the influence of a certain wind speed generated when the clothes dryer is working, the water entering the accommodating cavity 203 can be quickly evaporated and dried. In addition, when the wiring hole 205 is arranged at the lowest position of the accommodating cavity 203, the water in the accommodating cavity 203 can also be guided through the wiring hole 205, thereby further improving the waterproof performance of the circuit board 3.

[0067] In some other embodiments, a wire arranging channel can be arranged on the cavity wall of the air inlet cavity 201, for example, the wire arranging channel can be arranged below the wire hole 205, so as to facilitate the wire arrangement of the circuit board 3, and maximize the space utilization in the connecting base 2 and meet the waterproof requirement of the circuit board 3.

[0068] An optional embodiment of the application is shown in Figure 1 The display panel 4 is away from the end surface of the circuit board 3 and is embedded in the accommodating cavity 203.

[0069] In the embodiment of the application, the display panel 4 is away from the end surface of the circuit board 3, that is, the operating surface of the display panel 4, and is embedded in the accommodating cavity 203, so that the connecting base 2 located at the opening of the accommodating cavity 203 can shield the water flow, thereby avoiding the water flowing into the end of the display panel 4 close to the circuit board 3 from the opening of the accommodating cavity 203, and affecting the electrical performance of the circuit board 3. Therefore, the waterproof performance of the circuit board 3 can be further improved, and the long-term operation stability of the clothes dryer can be ensured.

[0070] For example, the distance between the end surface of the display panel 4 away from the circuit board 3 and the opening of the accommodating cavity 203 is at least 2 mm. Those skilled in the art can determine the distance between the end surface of the display panel 4 away from the circuit board 3 and the opening of the accommodating cavity 203 according to the actual waterproof test, which is not limited herein. Therefore, it can be ensured that the water droplets will not enter the end surface of the display panel 4 close to the circuit board 3 when the water droplets drop along the opening of the accommodating cavity 203.

[0071] An optional embodiment of the application is shown in Figure 1 , Figure 3 , Figure 5 and Figure 6 The connecting base 2 is a horizontally placed circular truncated cone structure, wherein the clothes dryer further comprises an air duct assembly 10 arranged in the first shell 1, and the air duct assembly 10 is coaxially arranged with the connecting base 2.

[0072] In the embodiment of the application, the connecting base 2 is a horizontally placed circular truncated cone structure, which can be understood as that the upper bottom surface of the connecting base 2 is parallel to the vertical direction, and the lower bottom surface of the connecting base 2 is parallel to the vertical direction. The upper bottom surface of the connecting base 2 is the end surface provided with the accommodating cavity 203, and the lower bottom surface of the connecting base 2 is the end surface connected with the first shell 1. The connecting base 2 is a circular truncated cone structure, which can improve the structural strength of the connecting base 2 and provide support for the circuit board 3 and the display panel 4.

[0073] An optional embodiment of the application is shown in Figure 1As shown, the clothes dryer can further include an air duct assembly 10 fixed in the mounting cavity 101, the air duct assembly 10 is coaxially arranged with the connecting base 2, that is to say, the central axis of the air duct assembly 10 coincides with the central axis of the connecting base 2. Therefore, when the air duct assembly 10 works, it is convenient for external air to quickly enter the mounting cavity 101 from the air inlet hole 202, thereby improving the air inlet amount of the clothes dryer and improving the drying efficiency.

[0074] An optional embodiment of the application is shown in Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown, the air inlet hole 202 is arranged on the side of the connecting base 2, and when the number of air inlet holes 202 is multiple, the air inlet holes 202 are uniformly distributed around the side of the connecting base 2.

[0075] In the embodiment of the application, the air inlet hole 202 can be arranged on the side of the connecting base 2, and since the connecting base 2 is a circular truncated cone structure, when multiple air inlet holes 202 are uniformly distributed around the side of the connecting base 2, air at each angle can enter the air duct assembly 10, thereby further increasing the air inlet amount.

[0076] The cross-sectional shape of the air inlet hole 202 can be circular, rectangular, etc., and the cross-sectional shape of the air inlet hole 202 can be determined by the actual design requirements, and is not limited herein. Multiple air inlet holes 202 can be arranged in a matrix on the connecting base 2 to form an air inlet grille, which is conducive to improving the air inlet amount of the clothes dryer.

[0077] In an example, the air duct assembly 10 can include a mounting bracket, a motor fixed on the mounting bracket, and a fan blade fixed on the output shaft of the motor. The mounting bracket is fixed on the first shell 1, and the motor is electrically connected with the circuit board 3, so that air pressure can be generated when the motor works to form air circulation.

[0078] Referring to Figure 1As shown, the clothes dryer can further include a second shell 11 arranged below the first shell 1, and an air inlet is formed on the second shell 11 and communicates with the mounting cavity 101, so that when the clothes dryer is working, air can enter through the air inlet on the second shell 11 and the air inlet hole 202 on the connecting base 2. The prior art clothes dryer usually arranges the air inlet of the clothes dryer on the bottom of the clothes dryer (i.e. on the second shell 11) rather than on the side where the display panel 4 is arranged. Therefore, the air inlet area of the bottom of the clothes dryer is limited, which cannot further improve the drying efficiency of the clothes dryer. The embodiment of the present application increases the connecting base 2 with an air inlet channel on the basis of the mounting hole for the circuit board 3, and the circuit board 3 is arranged on the connecting base 2, and the connecting base 2 is fixed on the first shell 1, so that the air inlet area is increased and the drying efficiency of the clothes dryer is improved on the basis of meeting the waterproof performance of the circuit board 3.

[0079] When the clothes dryer is drying clothes, if the air duct assembly 10 is working, external air enters the air inlet hole 202 and enters the air inlet cavity 201, and then enters the mounting cavity 101. Under the action of the working air pressure of the clothes dryer, when water enters the air inlet cavity 201 from the water inlet hole, it will move to the mounting cavity 101 of the first shell 1 due to the air pressure, so as to ensure the waterproof performance of the circuit board 3 at the position opposite to the air passage. Without the action of air pressure, when water enters the air inlet cavity 201 from the water inlet hole, it will be guided to a position lower than the heat dissipation hole 204 due to the arrangement of the water baffle 5, so as to ensure the waterproof performance of the circuit board 3.

[0080] Further, if a small amount of water enters the accommodating cavity 203 through the heat dissipation hole 204, the arrangement of the limiting rib 6 increases the distance between the heat dissipation hole 204 and the circuit board 3, so as to improve the waterproof performance of the circuit board 3. The water entering the accommodating cavity 203 will not contact the circuit board 3 and will not affect the electrical performance of the circuit board 3, and under the influence of a certain wind speed generated when the air duct assembly 10 is working, the water entering the accommodating cavity 203 can be quickly evaporated and dried. In addition, when the wiring hole 205 is arranged at the lowest position of the accommodating cavity 203, the water in the accommodating cavity 203 can also be guided through the wiring hole 205, so as to further improve the waterproof performance of the circuit board 3.

[0081] Reference Figure 2As shown, the clothes dryer can further include a third housing 12, which can be sleeved on the connecting base 2.

[0082] An optional embodiment of the application is shown in Figure 3 , Figure 4 and Figure 7 As shown, the accommodating cavity 203 is further provided with a first positioning rib 7, and the circuit board 3 is provided with a first positioning hole 301 which is shaped to match the first positioning rib 7, so that the circuit board 3 is positioned by the first positioning rib 7.

[0083] In the embodiment, the accommodating cavity 203 is further provided with a first positioning rib 7, which is used for accurate positioning of the circuit board 3. For example, after the limiting rib 6 limits the circuit board 3, the circuit board 3 is positioned at the assembly position, but the specific distribution of the two opposite ends of the circuit board 3 cannot be distinguished. Considering that the assembly position between the display panel 4 and the circuit board 3 is fixed, and the assembly angle of the display panel 4 on the connecting base 2 is fixed, a first positioning hole 301 can be formed on the circuit board 3 at a position corresponding to the first positioning rib 7, so that the circuit board 3 can be accurately positioned by the cooperation between the first positioning rib 7 and the first positioning hole 301. Therefore, during the assembly of the circuit board 3, the first positioning rib 7 can be aligned with the first positioning hole 301 in advance, and then the circuit board 3 can be placed on the limiting rib 6, thereby completing the assembly of the circuit board 3.

[0084] In some embodiments, the number of first positioning ribs 7 can be one, in other embodiments, the number of first positioning ribs 7 can be two, and in still other embodiments, the number of first positioning ribs 7 can be three. The number of first positioning ribs 7 can be determined by a person skilled in the art according to actual design requirements, and is not limited herein.

[0085] An optional embodiment of the application is shown in Figure 9 As shown, the display panel 4 is provided with a buckle 8 on an end surface close to the circuit board 3, and the accommodating cavity 203 is provided with a clamping groove 206 corresponding to the assembly position of the display panel 4, and the buckle 8 and the clamping groove 206 cooperate to clamp the display panel 4 on the connecting base 2.

[0086] In the embodiment of the present application, the display panel 4 is provided with buckles 8 on the end face close to the circuit board 3 (which can also be referred to as the back face of the display panel 4), and the number of the buckles 8 can be multiple. The number of the buckles 8 can be determined by the actual design requirements, for example, the number of the buckles 8 can be two, two buckles 8 are symmetrically arranged on the back face of the display panel 4 with respect to the center line of the display panel 4; for another example, the number of the buckles 8 can be three, three buckles 8 are distributed in a triangular shape on the back face of the display panel 4; for another example, the number of the buckles 8 can be four, four buckles 8 are distributed in a rectangular shape on the back face of the display panel 4. The number of the buckles 8 is not limited here.

[0087] The accommodating cavity 203 is provided with clamping grooves 206 corresponding to the assembly position of the display panel 4, and the number of the clamping grooves 206 is consistent with the number of the buckles 8, so that the first positioning ribs 7 and the first positioning holes 301 are aligned, and then the circuit board 3 is placed on the limiting ribs 6, and after the assembly of the circuit board 3 is completed, the display panel 4 can be clamped to the connecting base 2. Through the clamping cooperation of the buckles 8 and the clamping grooves 206, the assembly convenience of the display panel 4 can be improved. Moreover, the cost of fixing the display panel 4 and the connecting base 2 by using other fasteners such as screws and bolts can be reduced.

[0088] An optional embodiment of the present application is shown in FIGS. 1 to 3, and the display panel 4 is provided with positioning ribs 401 on the end face close to the circuit board 3, and the accommodating cavity 203 is provided with second positioning ribs 9, and the positioning ribs 401 and the second positioning ribs 9 cooperate to limit the position of the display panel 4 in the accommodating cavity 203. Figure 8 Figure 9 An optional embodiment of the present application is shown in FIGS. 1 to 3, and the display panel 4 is provided with positioning ribs 401 on the end face close to the circuit board 3, and the accommodating cavity 203 is provided with second positioning ribs 9, and the positioning ribs 401 and the second positioning ribs 9 cooperate to limit the position of the display panel 4 in the accommodating cavity 203.

[0089] In the embodiment of the present application, the display panel 4 is further provided with positioning ribs 401 on the end face close to the circuit board 3 (which can also be referred to as the back face of the display panel 4), and the positioning ribs 401 can be columnar structures provided with positioning holes, and the accommodating cavity 203 is provided with second positioning ribs 9, and the second positioning ribs 9 can also be columnar structures. The second positioning ribs 9 can be cross-shaped positioning ribs. The positioning ribs 401 and the second positioning ribs 9 can be gap-fitted to limit the position of the display panel 4 in the accommodating cavity 203, so that the display panel 4 can be quickly positioned after the assembly of the circuit board 3 is completed.

[0090] ​During assembly, the back of the display panel 4 completely covers the circuit board 3. Correspondingly, the second positioning rib 9 can be arranged around the display panel 4 within the receiving cavity 203. In some embodiments, there can be two second positioning ribs 9; in other embodiments, there can be three second positioning ribs 9. The number of positioning ribs 401 and the number of second positioning ribs 9 can be consistent, and those skilled in the art can determine the number of second positioning ribs 9 according to actual design requirements, without making excessive limitations here.

[0091] An optional embodiment of the invention, referring to... Figure 8 and Figure 9 As shown, a positioning post 402 is provided on the end face of the display panel 4 near the circuit board 3. The positioning post 402 abuts against the circuit board 3 to limit the relative position of the display panel 4 and the circuit board 3.

[0092] In this embodiment of the invention, a positioning post 402 is provided on the end face of the display panel 4 near the circuit board 3 (also referred to as the back of the display panel 4). The positioning post 402 abuts against the circuit board 3 to define the relative position between the display panel 4 and the circuit board 3. For example, the distance between the display panel 4 and the circuit board 3 can be controlled by the length of the positioning post 402, thereby ensuring the tactile feedback of the control buttons on the circuit board 3. It also ensures that the function buttons on the display panel 4 are consistent with the circuit buttons on the circuit board 3. The buttons on the display panel 4 can be touch-sensitive buttons to meet human-computer interaction requirements.

[0093] In some embodiments, the number of positioning posts 402 may be one; in other embodiments, the number of positioning posts 402 may be two; and in still other embodiments, the number of positioning posts 402 may be three. Those skilled in the art can determine the corresponding number of positioning posts 402 according to actual design requirements, and no further limitations are imposed here.

[0094] In the process of assembling the clothes dryer, the connecting base 2 can be first clamped to the first shell 1, and then the circuit board 3 is assembled. For example, the first positioning rib 7 can be aligned with the first positioning hole 301 formed on the circuit board 3, and then the circuit board 3 is placed on the limiting rib 6, that is, the assembly of the circuit board 3 is completed. Finally, the display panel 4 is assembled. For example, the positioning rib 401 and the second positioning rib 9 can be gap fitted to limit the position of the display panel 4 in the accommodating cavity 203. And at the same time, the relative position between the display panel 4 and the circuit board 3 is limited by the abutment between the positioning column 402 and the circuit board 3. Finally, the buckle 8 on the display panel 4 is clamped with the clamping groove 206 on the connecting base 2, that is, the assembly is completed.

[0095] In the case of drying clothes in the clothes dryer, if the air duct assembly 10 works, external air enters the air inlet cavity 201 from the air inlet hole 202, and enters the mounting cavity 101 through the air inlet cavity 201. Under the action of the working air pressure of the clothes dryer, when water enters the air inlet cavity 201 from the water inlet hole, it will move to the mounting cavity 101 of the first shell 1 due to the air pressure, thereby ensuring the waterproof performance of the circuit board 3 at the position opposite to the air passage. In the absence of air pressure, when water enters the air inlet cavity 201 from the water inlet hole, it will be guided to a position lower than the heat dissipation hole 204 due to the arrangement of the water baffle 5, thereby ensuring the waterproof performance of the circuit board 3.

[0096] Further, if a small amount of water enters the accommodating cavity 203 through the heat dissipation hole 204, the arrangement of the limiting rib 6 increases the distance between the heat dissipation hole 204 and the circuit board 3, thereby improving the waterproof performance of the circuit board 3. So that the water entering the accommodating cavity 203 will not contact the circuit board 3, and will not affect the electrical performance of the circuit board 3, and under the influence of a certain wind speed generated when the air duct assembly 10 works, the water entering the accommodating cavity 203 can be quickly evaporated and dried. In addition, by arranging the wiring hole 205 at the lowest position of the accommodating cavity 203, the water in the accommodating cavity 203 can also be guided through the wiring hole 205, thereby further improving the waterproof performance of the circuit board 3.

[0097] In summary, the clothes dryer disclosed by the embodiment of the present application can include a first shell 1, a connecting base 2, a circuit board 3 and a display panel 4, the connecting base 2 is installed on the first shell 1, the connecting base 2 is provided with an air inlet cavity 201 communicated with the first shell 1, and is provided with an air inlet hole 202 communicated with the air inlet cavity 201, wherein the end of the connecting base 2 away from the first shell 1 is provided with a containing cavity 203. The circuit board 3 is installed in the containing cavity 203, and the connecting base 2 is provided with a heat dissipation hole 204 communicated with the containing cavity 203 and the air inlet cavity 201. The display panel 4 is arranged on the end surface of the circuit board 3 away from the containing cavity 203 to seal the containing cavity 203. Thus, on the basis of the installation hole for the circuit board 3, the connecting base 2 with the air inlet channel is added, the circuit board 3 is installed on the connecting base 2, and then the connecting base 2 is fixed on the first shell 1, so that the air inlet area is increased and the drying efficiency of the clothes dryer is improved on the basis of meeting the waterproof performance of the circuit board 3.
