And potential risks (such as electric shock accidents) on personal safety of the user can be reduced, and the use experience of the user is improved.

Description

Technical Field

[0001] The present disclosure relates to the technical field of electrical equipment, and in particular to a support leg, a housing and an electrical equipment. Background Art

[0002] With the acceleration of modern life and the diversification of living space, more and more electrical appliances have emerged. However, once the electrical components of many electrical appliances come into contact with water, they may cause electrical faults such as short circuits and leakage, which will not only damage the equipment itself and shorten its service life, but also pose potential risks to the personal safety of users, such as electric shock accidents.

[0003] For example, folding clothes dryers, as a convenient and flexible clothes drying device, have been widely used in the market. In the current industry landscape, folding clothes dryers generally adopt a design structure that combines a base with an upper cover. When using this design, the user needs to open the upper cover, take out the internal accessories, and assemble it into a wardrobe shape for hanging and drying clothes. Whether in use or folded storage, the base always keeps in contact with the ground, which naturally forms a clear distinction between the front and bottom.

[0004] In actual use, folding clothes dryers need to meet the IPX1 waterproof rating standard. Although this waterproof rating requirement can cope with a certain degree of water splashing, in daily use scenarios, due to the different water content of wet clothes hung out by users, it is inevitable that some wet clothes will continue to drip. When these water droplets fall into the base of the folding clothes dryer, if they cannot be discharged in a timely and effective manner, they will pose a serious threat to the electrical components inside the base, and may cause electrical faults such as short circuits and leakage.

[0083] In order to solve the technical problem of untimely drainage in electrical equipment in the prior art, the present invention provides a support foot, a housing and an electrical equipment.

[0084] Among them, in the present disclosure, the support part of the support foot is used to place the support foot on the placement surface, and a drainage gap is set between the support part and the placement surface, and the main body of the support foot may include a receiving cavity and a guide hole, the guide hole is connected to the receiving cavity, and the support part includes a drainage hole, and the receiving cavity is connected to the drainage gap through the drainage hole. Based on this, when the support foot is placed in the placement groove at the bottom of the shell, the water leakage port, the guide hole, the receiving cavity, the drainage hole and the drainage gap on the placement groove constitute a drainage channel at the bottom of the shell, so that the water in the shell can be discharged in time. When the shell is applied to electrical equipment such as a dryer, through the cooperation of the above-mentioned support foot and the placement groove, the water in the shell can be discharged in time, so that water accumulation in the shell can be avoided, and the electrical components in the electrical equipment can be well prevented from contacting with water, thereby avoiding electrical faults such as short circuits and leakage, which can not only better protect the electrical equipment, but also reduce the potential risks to the personal safety of users (such as electric shock accidents), etc., and improve the user experience.

[0085] In an exemplary embodiment, an electrical device, a housing of the electrical device, and a support foot of the housing are provided. Figures 1 to 7 As shown, the support foot 1 may include a main body 11 and a support part 12 connected to each other, the support part 12 is used to place the support foot 1 on a placement surface (such as the ground), and a drainage gap 20 is provided between the support part 12 and the placement surface. The main body 11 includes a receiving cavity 10 and a guide hole 30, and the guide hole 30 is connected to the receiving cavity 10. The support part 12 includes a drainage hole 40, and the receiving cavity 10 is connected to the drainage gap 20 through the drainage hole 40.

[0086] Among them, reference Figure 1 and Fig.12 As shown, at least one placement groove 2 is provided at the bottom of the housing 100, and a water leakage port 50 is provided on the placement groove 2. The housing 100 includes at least one of the above-mentioned supporting feet 1, and at least one placement groove 2 corresponds to at least one supporting foot 1 one by one, that is, each supporting foot 1 is equipped with a placement groove 2, and the placement groove 2 is used to place the corresponding supporting foot 1.

[0087] Among them, reference Figures 1 to 7 as well as Figures 10 to 12 As shown, in the corresponding mounting grooves 2 and supporting feet 1, when the supporting feet 1 are mounted in the mounting grooves 2, the water leakage port 50, the guide hole 30, the accommodating cavity 10, the drainage hole 40 and the drainage gap 20 constitute a drainage channel at the bottom of the shell 100, which is used to discharge the accumulated water at the bottom of the shell 100 in time.

[0088] When the shell 100 is applied to electrical equipment, the water in the shell 100 can be discharged in time through the cooperation of the above-mentioned supporting feet 1 and the placement grooves 2, thereby avoiding water accumulation in the shell 100, and effectively preventing the electrical components in the electrical equipment from contacting with water, thereby avoiding electrical faults such as short circuits and leakages. It can not only better protect the electrical equipment, but also reduce potential risks to the user's personal safety (such as electric shock accidents), etc., thereby improving the user's experience.

[0089] For example, refer to Figures 1 to 7 As shown Figures 10 to 12 As shown, when the electrical device is a clothes dryer, when water accumulates in the housing 100 during operation of the clothes dryer, the accumulated water will flow through the water leakage port 50 on the placement groove 2 into the guide hole 30 of the main body 11 of the corresponding support foot 1, and then enter the accommodating chamber 10. For example, when drying a large amount of wet clothes, the moisture on the clothes may drip into the housing 100, and the accumulated water will quickly enter the accommodating chamber 10 of the support foot 1 according to the designed path. The accumulated water entering the accommodating chamber 10 flows into the drainage gap 20 between the support part 12 and the placement surface through the drainage hole 40. In the drainage gap 20, the accumulated water will diffuse outward along the edge of the support part 12, ensuring the continuity and stability of drainage. During the entire drainage process, the drainage work of each support foot 1 cooperates with each other to ensure that the accumulated water in the housing 100 can be quickly and comprehensively discharged.

[0090] In this embodiment, a complete and efficient drainage channel is formed by the one-to-one matching of the support foot 1 and the placement groove 2, which can ensure that almost no water will remain in the housing 100. This effectively prevents the electrical components in the electrical equipment from contacting with water, thereby preventing the occurrence of electrical faults such as short circuits and leakage. For example, when using a clothes dryer for a long time in a humid environment, the drainage channel can continue to work stably, ensure the safe operation of the equipment, reduce the potential risk to the user's personal safety, and greatly improve the user's experience.

[0091] In an exemplary embodiment, an electrical device, a housing of the electrical device, and a support foot of the housing are provided. Figures 1 to 7 as well as Fig.12 As shown, in this embodiment, the main body 11 may include a main column 111, an inverted skirt 112 and a connecting column 113. The main column 111 is connected to the inverted skirt 112 through the connecting column 113, and the guide hole 30 is located in the connecting column 113. The inner cavity of the main column 111, the inner cavity of the connecting column 113 and the cavity enclosed by the inverted skirt 112 constitute the accommodating cavity 10.

[0092] Among them, the support foot 1 can be an elastic structure made of an elastic material (such as silicone or rubber). When assembling the support foot 1 and the placement groove 2, the inverted skirt 112 of the support foot 1 can be aligned with the placement groove 2 at the bottom of the shell 100, and then the support foot 1 can be gently pressed to make the inverted skirt 112 elastically deform and gradually embed into the placement groove 2. During the embedding process, it is necessary to ensure that the water leakage port 50 on the placement groove 2 is accurately docked with the guide hole 30 of the connecting column 113 of the support foot 1. Due to the elasticity of the inverted skirt 112 and the size adaptation to the placement groove 2, it can fit tightly in the placement groove 2, and the connection structure between the connecting column 113 and the main column 111 is stable, ensuring that the entire support foot 1 is in a stable state after being installed in place. When the support foot 1 is fully installed in place, the inverted skirt 112 is tightly matched with the placement groove 2 to form a good seal and a stable connection structure.

[0093] The main column 111 can be cylindrical and made of a strong and corrosion-resistant plastic material, or made of a silicone or rubber material with good elasticity, without limitation. The inner cavity of the main column 111 is a cylindrical cavity, which is a part of the accommodating cavity 10 and mainly plays the role of supporting and stabilizing the entire supporting foot 1 structure, and can also accommodate a certain amount of accumulated water.

[0094] The inverted skirt 112 may be a trumpet-shaped structure, the bottom (i.e., the side with a larger opening) of which is connected to the first end of the connecting column 113, and is made of a silicone or rubber material with good elasticity, so that it can produce a certain deformation and fit tightly when installed in the housing 100 placement slot 2. The cavity enclosed by the inverted skirt 112, the inner cavity of the main column 111, and the inner cavity of the connecting column 113 together form the accommodating cavity 10.

[0095] The connecting column 113 is located between the main column 111 and the inverted skirt 112, and may be cylindrical, with its second end connected to the main column 111. The inner cavity of the connecting column 113 and the inner cavities of the main column 111 and the inverted skirt 112 together form the accommodating chamber 10. The guide hole 30 is located on the side of the connecting column 113, and the guide hole 30 may be circular, square, or other shapes, which are not limited to this. The guide hole 30 can smoothly introduce the accumulated water flowing into the leakage port 50 of the housing groove 2 of the shell 100 into the accommodating chamber 10. In addition, a plurality of guide holes 30 may be provided on the connecting column 113, and the plurality of guide holes 30 are distributed along the circumference of the connecting column 113 to enhance the drainage effect.

[0096] Among them, a reinforced connection structure is adopted at the connection parts between the connecting column 113 and the main column 111 and the inverted skirt 112, such as setting a transition fillet and increasing the connection thickness, so as to improve the stability and reliability of the overall structure and ensure that the components are firmly connected during long-term use without loosening or breaking.

[0097] The support portion 12 is connected to the main body 11, and may be disc-shaped and made of rubber material with good anti-slip performance. A drainage gap 20 is provided between the support portion 12 and the placement surface, and a drainage hole 40 is located on the side of the support portion 12 facing the main body 11 and communicated with the accommodating cavity 10, ensuring that the accumulated water in the accommodating cavity 10 can smoothly flow into the drainage gap 20 and be discharged.

[0098] Among them, the outer diameter of the connecting column 113 can be smaller than the outer diameter of the main column 111, and the outer diameter of the connecting column 113 can also be smaller than the outer diameter of the side of the inverted skirt 112 connected to the connecting column 113. Based on this, when the supporting foot 1 is placed in the mounting groove 2, a certain cavity can be formed between the connecting column 113 and the side wall of the supporting groove, and the leakage port 50 of the mounting groove 2 can be connected with the guide hole 30 on the connecting column 113 through the cavity.

[0099] The connecting column 113 may be provided with a plurality of guide holes 30 , and the plurality of guide holes 30 are distributed along the circumference of the connecting column 113 to improve the drainage effect.

[0100] Among them, reference Figure 7 As shown, the side wall of the placement groove 2 may be provided with a plurality of ribs 21 extending in the groove depth direction of the placement groove 2, and the plurality of ribs 21 are distributed along the side wall of the placement groove 2. The cross-sectional shape of the rib 21 may be semicircular or may be other shapes, which is not limited to this. The height of the rib 21 may be the same as the depth of the placement groove 2 or may be different from the depth of the placement groove 2, which is not limited to this. The provision of these ribs 21 not only enhances the structural strength of the side wall of the placement groove 2, but also plays a key role in positioning and fixing when connected to the support foot 1. For example, referring to Figures 6 to 9As shown, after the support foot 1 is installed in the mounting groove 2 , the undercut skirt 112 and the rib 21 are interference fit to achieve a reliable connection between the support foot 1 and the mounting groove 2 .

[0101] In this embodiment, whether the main column 111 is made of a strong and corrosion-resistant plastic material or a silicone or rubber material with good elasticity, its cylindrical structure can provide a stable support foundation. The main column 111 is connected to the inverted skirt 112 through a connecting column 113, and a transition fillet is set at the connection part and the connection thickness is increased to form a stable overall structure. For example, when bearing the weight of electrical equipment such as a dryer and the vibration during operation, this structure can effectively disperse the pressure and prevent the support foot 1 from deformation or damage, which can better ensure that the equipment always remains stable during operation and will not shake or tilt due to problems with the support foot 1, thereby ensuring the normal operation and service life of the equipment.

[0102] Among them, the ribs 21 arranged on the side walls of the placement groove 2, whether semicircular or in other shapes, can form an interference fit with the inverted skirt 112 when the support foot 1 is installed. This connection method allows the support foot 1 to be tightly connected to the housing 100 after being installed in place, and it will not easily become loose or displaced even if it is affected by factors such as temperature changes, humidity changes, and external force impacts during long-term use. For example, in a home environment, electrical equipment may cause significant changes in ambient temperature and humidity due to seasonal changes, or be hit due to frequent operations in commercial places, but the connection structure can still remain stable. This not only ensures the normal use of the equipment, but also reduces safety hazards and maintenance costs caused by loose connections.

[0103] In addition, refer to Figures 1 to 12 As shown, the outer diameter of the connecting column 113 is smaller than the outer diameter of the side where the main column 111 and the inverted skirt 112 are connected. When the support foot 1 is placed in the placement groove 2, the cavity formed between the connecting column 113 and the side wall of the support groove, together with the water leakage port 50 of the placement groove 2 and the guide hole 30 on the connecting column 113, forms an efficient drainage path (refer to Fig.11 The path shown by the arrow in the middle). The accumulated water can flow smoothly into the cavity from the water leakage port 50 of the placement groove 2, then enter the accommodating cavity 10 through the guide hole 30, and finally be discharged through the drainage hole 40 of the support part 12. When a plurality of guide holes 30 distributed along the circumferential direction are provided on the connecting column 113, the drainage efficiency can be further improved. For example, when dealing with a large amount of accumulated water, such as the accumulated water generated by a dryer drying multiple pieces of extremely wet clothes, this drainage structure can quickly drain the accumulated water and avoid the accumulation of accumulated water inside the device, effectively preventing electrical component short circuits, leakage and other faults that may be caused by accumulated water, and ensuring the electrical safety of the equipment.

[0104] Moreover, since the drainage channel of this embodiment is relatively spacious and has a certain cavity design, even if a small amount of impurities such as clothing fibers, dust, etc. are mixed into the accumulated water, it is not easy to cause blockage. Compared with the traditional narrow and single drainage pipe, this structure can accommodate a certain amount of impurities and take them out during the drainage process. For example, in daily household use, fibers on clothing are easy to fall off and enter the drainage channel with accumulated water, but the drainage structure of the support foot 1 can effectively deal with it, reducing the trouble of frequent cleaning of the drainage channel due to blockage, reducing maintenance costs, and improving the convenience of use of the equipment.

[0105] In an exemplary embodiment, an electrical device, a housing of the electrical device, and a support foot of the housing are provided. Figures 2 to 6 As shown, in this embodiment, the support portion 12 may include a support column 121 and a plurality of protrusions 122 (eg, bumps), and the plurality of protrusions 122 are dispersedly arranged on a side of the support column 121 facing the placement surface so that a drainage gap 20 is formed between the support portion 12 and the placement surface.

[0106] For example, the support column 121 can be made of rubber material, which has good elasticity and anti-slip performance. A plurality of protrusions 122 are dispersedly arranged on the side of the support column 121 facing the placement surface. The protrusions 122 can be hemispherical, and the plurality of protrusions 122 can be evenly distributed at the bottom of the support column 121. The arrangement of these protrusions 122 forms a drainage gap 20 between the support portion 12 and the placement surface. The drainage hole 40 is located on the side of the support portion 12 facing the main body 11, and is connected to the accommodating cavity 10, ensuring that the accumulated water in the accommodating cavity 10 can smoothly flow into the drainage gap 20 and be discharged.

[0107] Among them, reference Figures 1 to 11 As shown, the placement groove 2 includes an annular protrusion 122, which is located at the edge of the notch of the placement groove 2 and arranged along the circumference of the notch of the placement groove 2. The annular protrusion 122 protrudes from the outer side surface 110 of the bottom of the shell 100 in the direction away from the outer side surface 110. An annular flange 1211 is provided on the side of the support column 121 connected to the main body 11. When the support foot 1 is installed in the placement groove 2, the side of the annular protrusion 122 away from the outer side surface 110 abuts against the side of the annular flange 1211 facing the outer side surface 110, so that the annular flange 1211 covers the annular protrusion 122, so that the annular protrusion 122 on the shell 100 has no direct contact with the placement surface (such as the ground).

[0108] When assembling the electrical equipment, align the inverted skirt 112 of the support foot 1 with the placement groove 2 at the bottom of the housing 100, and gently press the support foot 1. The inverted skirt 112 is deformed by the elastic material under the pressure of the ribs 21 on the side wall of the placement groove 2, and gradually embeds into the placement groove 2. When the support foot 1 is completely embedded in the placement groove 2, a cavity of a predetermined width is formed between the connecting column 113 and the side wall of the placement groove 2, so that the leakage port 50 of the placement groove 2 can be connected with the guide hole 30 of the connecting column 113 through the cavity. In addition, the annular flange 1211 on the support column 121 interacts with the annular protrusion 122 of the placement groove 2. The side of the annular protrusion 122 facing away from the outer side surface 110 is in contact with the side of the annular flange 1211 facing the outer side surface 110, and the annular flange 1211 covers the annular protrusion 122, so that the annular protrusion 122 on the housing 100 has no direct contact with the placement surface (such as the ground).

[0109] When water accumulates in the housing 100 during the operation of an electrical device (such as a clothes dryer), the accumulated water flows into the cavity between the connecting column 113 and the side wall of the placement groove 2 through the water leakage port 50 at the bottom of the placement groove 2, and then enters the accommodating cavity 10 surrounded by the inner cavity of the main column 111, the inner cavity of the connecting column 113, and the inverted skirt 112 through the diversion hole 30. In the accommodating cavity 10, the accumulated water flows toward the support portion 12 under the action of gravity. When the accumulated water reaches the support portion 12, it flows into the drainage gap 20 between the support portion 12 and the placement surface through the drainage hole 40 on the side of the support portion 12 facing the main body 11. Since the drainage gap 20 is formed by the multiple protrusions 122 at the bottom of the support column 121, the accumulated water can flow smoothly in the gap and be discharged to the outside of the device. During the whole process, the annular flange 1211 covers and protects the annular protrusion 122, thereby avoiding direct contact between the housing 100 and the placement surface, preventing the housing 100 from scratching or wearing the placement surface during movement or use, and also preventing dust, stains, etc. on the placement surface from contaminating the bottom of the housing 100. For example, in home use, when the dryer needs to be moved, even if the support foot 1 slides on the ground, the annular flange 1211 can protect the placement surface from being scratched by the annular protrusion 122 at the bottom of the housing 100, keeping the placement surface clean and beautiful.

[0110] A drainage cavity 60 is formed between the support column 121 and the placement surface, and a drainage hole 40 is provided on the side of the support column 121 facing the main body 11, and the drainage hole 40 is connected to the drainage gap 20 through the drainage cavity 60. For example, the drainage cavity 60 is constructed as an umbrella-shaped cavity, and the diameter of the umbrella-shaped cavity gradually increases from the drainage hole 40 toward the placement surface. When the accumulated water reaches the support part 12, it flows into the umbrella-shaped drainage cavity 60 through the drainage hole 40 on the side of the support column 121 facing the main body 11. Due to the special shape of the umbrella-shaped cavity, the accumulated water can be evenly dispersed in the cavity and smoothly flow to the drainage gap 20 between the bottom of the support column 121 and the placement surface, thereby improving the drainage effect.

[0111] In an exemplary embodiment, an electrical device, a housing of the electrical device, and a support foot of the housing are provided. Figures 7 to 11 As shown, in this embodiment, the placement groove 2 has a residual gate 23 of the shell 100 , the size of the accommodating cavity 10 is larger than the size of the residual gate 23 , and the accommodating cavity 10 is used to accommodate the residual gate 23 .

[0112] It should be noted that the mold is divided into a fixed mold and a movable mold. The gate of the mold is set on one side of the fixed mold, and the fixed mold side happens to be the appearance surface of the product, and the movable mold side is the internal surface of the product. The gate can be made on the fixed mold side, that is, the gate is made on the side where the appearance surface is located, but the shell 100 is an appearance part of the electrical equipment. Since each appearance surface of the appearance part can be seen by the user, in order to improve the appearance, it is necessary to find a hidden place on the fixed mold side to set the gate.

[0113] In order to ensure that the outer surface of the shell 100 does not directly contact the placement surface, a plurality of placement grooves 2 are provided on the shell 100. After the support foot 1 is installed, the outer surface of the shell 100 can avoid direct contact with the placement surface by the support foot 1 abutting against the placement surface. At the same time, the support foot 1 can also cover the structure in the placement groove 2, so the best position of the gate is selected in the placement groove 2. It should be noted that a part of the gate in the placement groove 2 will remain and cannot be cut off, because the size of the placement groove 2 is relatively small, and it is difficult for tools to enter, and in this case, it is very time-consuming and laborious to manually cut the gate. There is a residual gate 23 in the placement groove 2, and the residual gate 23 needs to be avoided.

[0114] That is, in this embodiment, the residual gate 23 is arranged in the placement groove 2, and after the support leg 1 is placed in the placement groove 2, the residual gate 23 is accommodated in the accommodation cavity 10 of the support leg 1. In addition, the size of the accommodation cavity 10 is set to be larger than the size of the residual gate 23, which can ensure that the residual gate 23 is fully accommodated, and after accommodating the residual gate 23, some space can still be reserved for drainage.

[0115] Among them, reference Figure 1as well as Figures 8 to 14 As shown, the housing 100 may include a first housing portion 101 and a second housing portion 102, the first housing portion 101 and the second housing portion 102 are rotatably connected, and the first housing portion 101 and the second housing portion 102 can achieve 0°-180° rotation, so that the housing 100 has a first state and a second state. When the housing 100 is in the first state, the angle between the first housing portion 101 and the second housing portion 102 is 0°, and the first housing portion 101 and the second housing portion 102 are in a folded state (i.e., a stored state), so that the opening side of the first housing portion 101 is buckled with the opening side of the second housing portion 102. When the housing 100 is in the second state, the angle between the first housing portion 101 and the second housing portion 102 is 180°, and the first housing portion 101 and the second housing portion 102 are in an unfolded state.

[0116] When the electrical device is a clothes dryer, the clothes dryer may include a storage-type clothes drying rack 200, and the clothes drying rack 200 includes a clothes hanger 201 and a clothes rod 202 for supporting the clothes hanger 201. When the housing 100 is in the first state, the clothes drying rack 200 is stored in the housing 100, and this state can also be called the storage state of the clothes dryer. When the housing 100 is in the second state, the clothes drying rack 200 and the housing 100 are both unfolded, the clothes hanger 201 is supported on the inner side of the housing 100 by the clothes rod 202, and the outer side surface 110 of the housing 100 is placed on the placement surface through the supporting feet 1, and the housing 100 constitutes the base of the clothes drying rack 200, and this state can be called the clothes drying state of the clothes dryer.

[0117] Among them, the shell 100 can reduce the storage volume after folding, and can increase the drying capacity after unfolding, which can solve the contradiction between large capacity and small storage volume in the clothes dryer. In the shell 100 of this embodiment, in the storage state, one of the shell parts is rotated 180° and rotated to the top to become the upper appearance surface, but in the unfolded state (i.e., the clothes drying state), the outer side surfaces 110 of the bottom of the two shell parts are in contact with the placement surface. Therefore, both shell parts have drainage requirements and take into account the appearance requirements. The appearance surfaces of the two shell parts in this embodiment are provided with placement grooves 2 for placing the support feet 1, so that the drainage effect can be well guaranteed.

[0118] In some embodiments,

[0119] refer to Figures 1 to 14As shown, the electrical device may be a clothes dryer, such as a rotary folding clothes dryer. The housing 100 of the clothes dryer may include a first housing 101 and a second housing 102. The first housing 101 and the second housing 102 may rotate relative to each other and may achieve a rotation of 0°-180°. When the angle between the first housing 101 and the second housing 102 rotates to 0°, the clothes dryer is in a stored state; when the first housing 101 and the second housing 102 rotate to 180°, the clothes dryer is in an unfolded state. Support feet 1 are provided on the outer surfaces of the first housing 101 and the second housing 102.

[0120] The first shell part 101 and the second shell part 102 are both appearance parts. Since the appearance surfaces of the first shell part 101 and the second shell part 102 can be seen by the user after the shell 100 is folded, in order to improve the appearance, no traces of the gate should be left on the appearance surface. In order to ensure that the outer side surface 110 of the bottom in the unfolded state does not directly contact the ground, the outer side surface 110 of the first shell part 101 and the second shell part 102 are both provided with a plurality of mounting grooves 2 for the support legs 1. After the support legs 1 are placed in the mounting grooves 2, the outer side surface 110 can be prevented from directly contacting the ground. At the same time, the support legs 1 can also cover the structure in the mounting grooves 2. Therefore, the best position for the remaining gate can be selected in the mounting grooves 2.

[0121] The placement groove 2 may include an annular protrusion 122, ribs 21, a water leak 50, and a residual gate 23. Because the structural features set in the support foot 1 require a certain height space, the annular protrusion 122 protrudes outward (i.e., protrudes in a direction away from the inner side of the housing 100), and the groove body of the placement groove 2 protrudes inward, thereby ensuring that a cavity for accommodating the support foot 1 is formed.

[0122] The placement groove 2 may include a plurality of ribs 21 distributed around the side of the placement groove 2. Because the inner side of the annular protrusion 122 is fitted with the side of the support foot 1 by interference, the support foot 1 is fixed. The height of the interference here is just the height difference between the rib 21 and the annular protrusion 122. If the height of the rib 21 is the same as the height of the annular protrusion 122, the support foot 1 cannot be inserted into the placement groove 2 and will be supported by the rib 21. Therefore, the height of the rib 21 needs to be lower than the annular protrusion 122, so that the installation of the support foot 1 can be better ensured.

[0123] Among them, the leakage port 50 of the mounting groove 2 connects the inner cavity of the shell 100 with the mounting groove 2. For the gate, because it is immersed in the mounting groove 2 of the supporting foot 1, the gate to the inner part of the annular protrusion 122 cannot be withdrawn with the mold, and a residual gate 23 is formed in the mounting groove 2. The residual gate 23 can be located at the center of the mounting groove 2. It should be noted that the residual gate 23 does not have to be located in the center, but it is a more appropriate location to be located in the center. The residual gate 23 is located in the center because the whole machine is designed with multiple supporting feet 1. If the residual gate 23 is not located in the center, the avoidance space of the supporting foot 1 is also not located in the center. It must be directional during production and assembly, which is equivalent to structural fool-proofing; if it is located in the center, it can be assembled at will to improve production efficiency.

[0124] Among them, the support foot 1 can be made of silicone or rubber material, with a certain elasticity, and can include an inverted skirt 112, a protrusion 122, a guide hole 30, a drainage hole 40 and a receiving chamber 10, etc., wherein the inverted skirt 112 can be a rotating body with a triangular step cross section, which will be compressed and deformed after being subjected to force. The receiving chamber 10 is a cylindrical cavity located in the center of the support foot 1. There are several guide holes 30, connecting the outside with the receiving chamber 10. The drainage hole 40 is located at the bottom center of the support foot 1 and is connected to the receiving chamber 10. The drainage hole 40 has a certain height from the ground and is not in direct contact with the ground. Around the bottom drainage hole 40, the distance from the center axis to the outside and the drainage hole 40 to the ground gradually decreases until it contacts. Based on this, an umbrella-shaped cavity is formed around the bottom of the drainage hole 40, that is, the drainage cavity 60. There are a plurality of protrusions 122 distributed in a ring shape around the umbrella-shaped cavity and in direct contact with the ground, and gaps are left between adjacent protrusions 122, so as to form a drainage gap 20 between the support foot 1 and the ground.

[0125] It should be noted that the protrusions 122 are provided to support the support foot 1 from the ground, and the gaps between the protrusions 122 are used for drainage. If the protrusions 122 are not provided, the bottom surface of the support foot 1 will be in direct contact with the ground, so that the water flowing from the center of the support foot 1 will be sealed inside the support foot 1 and will be difficult to seep out from the surroundings, which is not conducive to the water inside the housing 100 being drained to the outside.

[0126] Among them, after the support foot 1 is installed on the shell 100, there is interference between the inverted skirt 112 of the support foot 1 and the ribs 21 in the placement groove 2. Because the material of the support foot 1 is elastic, it is pressed by the ribs 21 around the placement groove 2, making it difficult to escape from the placement groove 2. The accommodating cavity 10 of the support foot 1 is used to avoid the residual gate 23 of the shell 100. At the same time, one side of the accommodating cavity 10 is connected to the guide hole 30 and the other side is connected to the drainage hole 40. The diameter and depth of the accommodating cavity 10 are larger than the residual gate 23. The accommodating cavity 10 is connected to the umbrella-shaped cavity through the drainage hole 40, and the guide hole 30 is connected to the leaking port 50. Therefore, the water inside the shell 100 flows out to the outside through the leaking port 50, the guide hole 30, the accommodating cavity 10, the drainage hole 40, the drainage cavity 60, and the drainage gap 20 in sequence.

[0127] Among them, the support foot 1 may include an annular flange 1211, and the annular flange 1211 contacts the annular protrusion 122 of the mounting groove 2, covering the annular protrusion 122, so that the annular protrusion 122 has no direct contact with the ground. There is an interference between the side of the main column 111 of the support foot 1 and the side of the rib 21 in the mounting groove 2. Because the material of the support foot 1 is elastic, the main column 111 of the support foot 1 is pressed by the rib 21 in the mounting groove 2, so that it will not fall out after assembly. In addition, the end of the side of the main column 111 of the support foot 1 (that is, the side connected to the connecting column 113) is designed to be a C angle 1111, which is convenient for the support foot 1 to be installed into the mounting groove 2.

[0128] In this embodiment, through the support foot 1 and the placement groove 2 on the housing 100, after the support foot 1 is installed in the placement groove 2, not only can the water that penetrates into the housing 100 during the operation of the dryer be discharged to the outside in time, but also it can ensure that the housing 100 does not need to have a separate drainage hole 40, avoiding the destruction of integrity and aesthetics due to the opening of the exterior surface. At the same time, the support foot 1 also takes into account the shielding of the residual gate 23 of the mold on the housing 100, which not only shields the unsightly residual gate 23, but also meets the drainage requirements, and can also prevent the exterior surface from direct contact with the ground, thereby avoiding surface scratches.

[0129] In addition, a flow guide structure may be provided inside the housing 100. If a flow guide structure is provided, the position where the external water flows in must be considered. Generally, the water inlet position is located at the gap between the two shell parts and the air duct drainage hole 40 of the dryer. A water retaining rib 30021 may be provided inside the housing 100. The water retaining rib 30021 and the side of the housing 100 form a water area 401 (such as Fig.12 The water area 401 includes a placement groove 2 to facilitate drainage. The water-free area 402 contains live parts such as heating element terminals and motherboards to prevent live parts from contacting water (such as Fig.12 shown).

[0130] It should be noted that the housing 100 of this embodiment can be applied not only to a clothes dryer but also to other electrical appliances, such as an indoor heater, a fan, and the like.

[0131] In this embodiment, after the support foot 1 is placed in the placement groove 2 at the bottom of the housing 100, the water leakage port 50, the guide hole 30, the accommodating cavity 10, the drainage hole 40 and the drainage gap 20 on the placement groove 2 constitute a drainage channel at the bottom of the housing 100, so that the water in the housing 100 can be discharged in time. When the housing 100 is applied to electrical equipment such as a clothes dryer, the water in the housing 100 can be discharged in time through the cooperation of the support foot 1 and the placement groove 2, thereby avoiding water accumulation in the housing 100, and thus preventing the electrical components in the electrical equipment from contacting with water, thereby avoiding electrical faults such as short circuits and leakage, which can not only better protect the electrical equipment, but also reduce the potential risks to the personal safety of users (such as electric shock accidents), etc., and improve the user experience.
