Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of electrical appliances, and in particular to a supporting leg, a shell, and an electrical appliance. BACKGROUND

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

[0003] For example, as a convenient and flexible clothes drying device, the folding clothes dryer has been widely used in the market. In the current industry pattern, the folding clothes dryer generally adopts a design architecture combining a base with an upper cover. When in use, the user needs to open the upper cover and take out the internal accessories to assemble them into a wardrobe shape for hanging and drying clothes. Whether in a use state or a folded storage state, the base is always in contact with the ground, thereby naturally forming a clear distinction between the front and the bottom.

[0004] In actual use, the folding clothes dryer needs to meet the IPX1 waterproof level standard. Although this waterproof level requirement can cope with a certain degree of water splashing, in the daily use scene, due to the different water contents of the wet clothes hung by the user, it is inevitable that some wet clothes will continue to drip water. When these water droplets fall into the inside of the base of the folding clothes dryer, if they cannot be effectively drained in time, they will pose a serious threat to the electrical components inside the base and may cause electrical faults such as short circuit and electric leakage.

[0083] In order to solve the technical problem of not timely drainage in the prior art electric appliance, the present disclosure provides a support leg, a shell and an electric appliance.

[0084] In the present disclosure, the support part of the support leg is used to place the support leg on the placement surface, and a drainage gap is arranged between the support part and the placement surface, and the main part of the support leg can include a containing cavity and a flow guide hole, the flow guide hole is communicated with the containing cavity, the support part includes a drainage hole, and the containing cavity is communicated with the drainage gap through the drainage hole. Based on this, when the support leg is placed in the placement groove at the bottom of the shell, the water leakage opening on the placement groove, the flow guide hole, the containing cavity, the drainage hole and the drainage gap constitute the drainage channel at the bottom of the shell, so that the water in the shell can be drained in time. When the shell is applied to an electric appliance such as a clothes dryer, the water in the shell can be drained in time through the cooperation of the above-mentioned support leg and placement groove, so as to avoid water accumulation in the shell, and the electrical components in the electric appliance can be well avoided from being in contact with water, thereby avoiding electrical faults such as short circuit and electric leakage, not only better protecting the electric appliance, but also reducing the potential risk to the personal safety of the user (such as electric shock accident) and improving the user's experience.

[0085] In one exemplary embodiment, an electric appliance, a shell of the electric appliance and a support leg of the shell are provided. Referring to Figures 1 to 7 As shown, the support leg 1 can include a main part 11 and a support part 12 connected to each other, the support part 12 is used to place the support leg 1 on a placement surface (such as the ground), and a drainage gap 20 is arranged between the support part 12 and the placement surface. The main part 11 includes a containing cavity 10 and a flow guide hole 30, the flow guide hole 30 is communicated with the containing cavity 10. The support part 12 includes a drainage hole 40, and the containing cavity 10 is communicated with the drainage gap 20 through the drainage hole 40.

[0086] In the present disclosure, the support part of the support leg is used to place the support leg on the placement surface, and a drainage gap is arranged between the support part and the placement surface, and the main part of the support leg can include a containing cavity and a flow guide hole, the flow guide hole is communicated with the containing cavity, the support part includes a drainage hole, and the containing cavity is communicated with the drainage gap through the drainage hole. Based on this, when the support leg is placed in the placement groove at the bottom of the shell, the water leakage opening on the placement groove, the flow guide hole, the containing cavity, the drainage hole and the drainage gap constitute the drainage channel at the bottom of the shell, so that the water in the shell can be drained in time. When the shell is applied to an electric appliance such as a clothes dryer, the water in the shell can be drained in time through the cooperation of the above-mentioned support leg and placement groove, so as to avoid water accumulation in the shell, and the electrical components in the electric appliance can be well avoided from being in contact with water, thereby avoiding electrical faults such as short circuit and electric leakage, not only better protecting the electric appliance, but also reducing the potential risk to the personal safety of the user (such as electric shock accident) and improving the user's experience. Figure 1 andFigure 12 As shown, the bottom of the shell 100 is provided with at least one installation groove 2, and the installation groove 2 is provided with a water leakage opening 50. The shell 100 includes at least one support leg 1 described above, and at least one installation groove 2 corresponds to at least one support leg 1, that is, each support leg 1 is provided with an installation groove 2, and the installation groove 2 is used to install the corresponding support leg 1.

[0087] Wherein, referring to Figures 1 to 7 And Figures 10 to 12 As shown, the corresponding installation groove 2 and the support leg 1, when the support leg 1 is installed in the installation groove 2, the water leakage opening 50, the flow guide hole 30, the containing cavity 10, the drainage hole 40 and the drainage gap 20 constitute a drainage channel of the bottom of the shell 100, which is used to drain the water accumulated at the bottom of the shell 100 in time.

[0088] When the shell 100 is applied to an electrical appliance, through the cooperation of the support leg 1 and the installation groove 2, the water in the shell 100 can be drained in time, so as to avoid water accumulation in the shell 100, and the electrical components in the electrical appliance can be well prevented from being in contact with water, thereby avoiding electrical faults such as short circuit and electric leakage, not only better protecting the electrical appliance, but also reducing potential risks to the personal safety of the user (such as electric shock accidents) and improving the user experience.

[0089] For example, referring to Figures 1 to 7 As shown, and Figures 10 to 12 As shown, when the electrical appliance is a clothes dryer, when water accumulates in the shell 100 during the operation of the clothes dryer, the water will flow into the flow guide hole 30 of the main body part 11 of the corresponding support leg 1 through the water leakage opening 50 on the installation groove 2, and then enter the containing cavity 10. For example, when a large amount of wet clothes is dried, the water on the clothes may fall into the shell 100, and these accumulated water will quickly enter the containing cavity 10 of the support leg 1 according to the designed path. The accumulated water in the containing cavity 10 flows into the drainage gap 20 between the support part 12 and the installation surface through the drainage hole 40. In the drainage gap 20, the accumulated water spreads outward along the edge of the support part 12, ensuring the continuity and stability of the drainage. During the entire drainage process, the drainage work of each support leg 1 is coordinated with each other, ensuring that the accumulated water in the shell 100 can be quickly and comprehensively drained.

[0090] In this embodiment, through the one-to-one cooperation of the support leg 1 and the installation groove 2, a complete and efficient drainage channel is formed, which can ensure that there is almost no accumulated water in the shell 100. In this way, the electrical components in the electrical appliance can be effectively prevented from being in contact with water, thereby preventing the occurrence of electrical faults such as short circuit and electric leakage. For example, when the clothes dryer is used for a long time in a humid environment, the drainage channel can work continuously and stably, ensuring the safe operation of the device, reducing the potential risks to the personal safety of the user, and greatly improving the user experience.

[0091] In one example embodiment, an electrical appliance, a housing of the electrical appliance, and a support leg of the housing are provided. Referring to Figures 1 to 7 and Figure 12 In this embodiment, the main body 11 can include a main column 111, a reverse- threaded skirt 112, and a connecting column 113. The main column 111 is connected to the reverse-threaded skirt 112 through the connecting column 113, and the flow 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 reverse-threaded skirt 112 constitute the containing cavity 10.

[0092] The support leg 1 can be made of an elastic structure made of an elastic material such as silicone or rubber. When assembling the support leg 1 and the installation groove 2, the reverse-threaded skirt 112 of the support leg 1 can be aligned with the installation groove 2 at the bottom of the housing 100, and then the support leg 1 can be gently pressed so that the reverse-threaded skirt 112 is elastically deformed and gradually embedded in the installation groove 2. During the embedding process, it is necessary to ensure that the water leakage opening 50 on the installation groove 2 is accurately connected to the flow guide hole 30 of the connecting column 113 of the support leg 1. Due to the elasticity of the reverse-threaded skirt 112 and the size adaptation with the installation groove 2, the reverse-threaded skirt 112 can be tightly fitted in the installation groove 2, and the connecting structure of the connecting column 113 and the main column 111 is stable, ensuring that the entire support leg 1 is installed in place and is in a stable state. After the support leg 1 is completely installed in place, the reverse-threaded skirt 112 is tightly fitted with the installation groove 2, forming a good sealing and stable connecting structure.

[0093] The main column 111 can be cylindrical and made of a firm and corrosion-resistant plastic material, or made of silicone or rubber with good elasticity, which is not limited. The inner cavity of the main column 111 is a cylindrical cavity, which is part of the containing cavity 10, mainly plays a role in supporting and stabilizing the structure of the entire support leg 1, and can also contain a certain amount of accumulated water.

[0094] The reverse-threaded skirt 112 can be a flared structure, the bottom thereof (i.e., the side with a larger opening) is connected to the first end of the connecting column 113, and is made of silicone or rubber with good elasticity, so that it can be deformed and tightly fitted when installed in the installation groove 2 of the housing 100. The cavity enclosed by the reverse-threaded skirt 112, together with the inner cavities of the main column 111 and the connecting column 113, constitutes the containing cavity 10.

[0095] The connecting column 113 is located between the main column 111 and the inverted skirt 112, which can be cylindrical, and the second end of which is 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 containing cavity 10. The flow guide hole 30 is located on the side of the connecting column 113, which can be circular, square, or other shapes, which are not limited. The flow guide hole 30 can smoothly guide the accumulated water flowing from the water leakage hole 50 of the housing 100 into the containing cavity 10. In addition, multiple flow guide holes 30 can be provided on the connecting column 113, and the multiple flow guide holes 30 are distributed along the circumference of the connecting column 113 to improve the drainage effect.

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

[0097] The support part 12 is connected to the main part 11 and can be disc-shaped, made of rubber material, and has good anti-skid performance. The drainage gap 20 is provided between the support part 12 and the placement surface, and the drainage hole 40 is located on the side of the support part 12 facing the main part 11 and is in communication with the containing cavity 10, so as to ensure that the accumulated water in the containing cavity 10 can flow into the drainage gap 20 and be drained out.

[0098] 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 support foot 1 is placed in the placement groove 2, a certain cavity can be formed between the connecting column 113 and the side wall of the support groove, and the water leakage hole 50 of the placement groove 2 can be in communication with the flow guide hole 30 on the connecting column 113 through the cavity.

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

[0100] As shown in Figure 7 The side wall of the placement groove 2 can be provided with multiple ribs 21 extending along the depth direction of the placement groove 2, and the multiple ribs 21 are distributed along the side wall of the placement groove 2. The cross-sectional shape of the rib 21 can be semicircular or other shapes, which are not limited. The height of the rib 21 can be the same as the depth of the placement groove 2, or different from the depth of the placement groove 2, which is not limited. The setting 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 with the support foot 1. For example, as shown in Figures 6 to 9As shown, when the support leg 1 is installed in the installation groove 2, the reverse buckle skirt 112 is in interference fit with the rib 21 to achieve reliable connection of the support leg 1 and the installation groove 2.

[0101] In this embodiment, the main column body 111, whether made of a strong and corrosion-resistant plastic material or a flexible silicone or rubber material, provides a stable support base with its cylindrical structure. The main column body 111 is connected to the reverse buckle skirt 112 through the connecting column body 113, and a transition round corner and increased connection thickness are provided at the connection part to form a stable overall structure. For example, when bearing the weight of an electrical appliance such as a clothes dryer and the vibration during operation, this structure can effectively disperse the pressure and prevent the support leg 1 from deforming or being damaged, so that the appliance can always remain stable during operation and will not shake or tilt due to the problem of the support leg 1, thereby ensuring the normal operation and service life of the appliance.

[0103] In addition, referring to Figures 1 to 12 As shown, the outer diameter of the connecting column body 113 is smaller than the outer diameter of the side of the main column body 111 connected to the reverse buckle skirt 112. When the support leg 1 is installed in the installation groove 2, a cavity is formed between the connecting column body 113 and the side wall of the support groove, which, together with the water leakage opening 50 of the installation groove 2 and the flow guide hole 30 on the connecting column body 113, constitutes an efficient drainage path (refer to the path indicated by the arrow in Figure 11 When multiple circumferentially distributed flow guide holes 30 are provided on the connecting column body 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 drying a large number of extremely wet clothes in a clothes dryer, this drainage structure can quickly drain the accumulated water, avoiding the accumulation of water inside the appliance, effectively preventing electrical component short circuits, electrical leakage and other faults that may be caused by accumulated water, and ensuring the electrical safety of the appliance.

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

[0105] In one example embodiment, an electric appliance, a housing of the electric appliance, and a support foot of the housing are provided. Referring to Figures 2 to 6 As shown, in the embodiment, the support part 12 can include a support column 121 and a plurality of protrusions 122 (e.g. bumps), which are dispersedly arranged on the side of the support column 121 facing the placement surface, so that a drainage gap 20 is formed between the support part 12 and the placement surface.

[0106] For example, the support column 121 can be made of rubber material, having good elasticity and anti-skid performance. The plurality of protrusions 122 are dispersedly arranged on the side of the support column 121 facing the placement surface, and the protrusions 122 can be hemispherical. The plurality of protrusions 122 can be uniformly distributed on the bottom of the support column 121. The arrangement of these protrusions 122 forms a drainage gap 20 between the support part 12 and the placement surface. The drainage hole 40 is located on the side of the support part 12 facing the main body part 11 and is in communication with the accommodation cavity 10, ensuring that the accumulated water in the accommodation cavity 10 can flow smoothly into the drainage gap 20 and be drained out.

[0107] Referring to Figures 1 to 11 As shown, the placement groove 2 includes an annular protrusion 122 part located at the edge of the slot of the placement groove 2 and arranged along the circumference of the slot of the placement groove 2. The annular protrusion 122 part is protruded from the outer side surface 110 of the bottom of the housing 100 in the direction away from the outer side surface 110. The side of the support column 121 connected to the main body part 11 is provided with an annular flange 1211. When the support foot 1 is installed in the placement groove 2, the side of the annular protrusion 122 part 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 part, so that the annular protrusion 122 part on the housing 100 has no direct contact with the placement surface (e.g. the ground).

[0108] In the process of assembling the electrical appliance, the inverted skirt 112 of the supporting leg 1 is aligned with the installation groove 2 at the bottom of the housing 100, and the supporting leg 1 is gently pressed. The inverted skirt 112 is deformed due to the elastic material under the extrusion of the side wall rib 21 of the installation groove 2, and gradually embedded in the installation groove 2. When the supporting leg 1 is completely embedded in the installation groove 2, a cavity with a predetermined width is formed between the connecting column 113 and the side wall of the installation groove 2, so as to ensure that the water leakage opening 50 of the installation groove 2 communicates with the flow guide hole 30 of the connecting column 113 through the cavity. Moreover, the annular flange 1211 on the supporting column 121 interacts with the annular protrusion 122 part of the installation groove 2. The side of the annular protrusion 122 part away from the outer side surface 110 abuts against the side of the annular flange 1211 facing the outer side surface 110, and the annular flange 1211 covers the annular protrusion 122 part, so that the annular protrusion 122 part on the housing 100 has no direct contact with the installation surface (such as the ground).

[0109] When water accumulates in the housing 100 during the operation of the electrical appliance (such as a clothes dryer), the water flows into the cavity between the connecting column 113 and the side wall of the installation groove 2 through the water leakage opening 50 at the bottom of the installation groove 2, and then enters the containing cavity 10 enclosed by the inner cavity of the main column 111, the inner cavity of the connecting column 113 and the inverted skirt 112. In the containing cavity 10, the water flows to the supporting part 12 under the action of gravity. When the water reaches the supporting part 12, it flows into the drainage gap 20 between the supporting part 12 and the installation surface through the drainage hole 40 on the side of the supporting part 12 facing the main body part 11. Since the plurality of protrusions 122 at the bottom of the supporting column 121 form the drainage gap 20, the water can flow smoothly in the gap and be discharged to the outside of the device. In the whole process, the annular flange 1211 covers the annular protrusion 122 part, avoiding direct contact between the housing 100 and the installation surface, preventing the housing 100 from scratching or wearing the installation surface during movement or use, and also preventing the installation surface from polluting the bottom of the housing 100 with dust, stains and the like. For example, in home use, when the clothes dryer needs to be moved, even if the supporting leg 1 slides on the ground, the annular flange 1211 can also protect the installation surface from being scratched by the annular protrusion 122 part at the bottom of the housing 100, keeping the installation surface clean and beautiful.

[0110] The support column 121 and the placement surface form a drainage cavity 60, and the side of the support column 121 facing the main body 11 is provided with a drainage hole 40, which is communicated with the drainage gap 20 through the drainage cavity 60. For example, the drainage cavity 60 is configured as an umbrella-shaped cavity, and the diameter of the umbrella-shaped cavity gradually increases from the direction of the drainage hole 40 to 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 uniformly 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 one example embodiment, an electric appliance, a housing of the electric appliance, and a support leg of the housing are provided. With reference to Figures 7 to 11 As shown, in this embodiment, the placement slot 2 has a residual gate 23 of the housing 100, and the size of the accommodation cavity 10 is greater than that of the residual gate 23, and the accommodation cavity 10 is used to accommodate the residual gate 23.

[0112] It should be noted that for the mold, it is divided into a fixed mold and a movable mold, and the gate of the mold is arranged on the side of the fixed mold, and the side of the fixed mold is the appearance surface of the product, and the side of the movable mold is the internal surface of the product. The gate can be arranged on the side of the fixed mold, that is, on the side of the appearance surface, but the housing 100 belongs to the appearance part of the electric appliance, and since each appearance surface of the appearance part can be seen by the user, in order to improve the appearance beauty, the gate needs to be arranged in a place that can be hidden on the side of the fixed mold.

[0113] In order to ensure that the outer surface of the housing 100 does not directly contact the placement surface, a plurality of placement slots 2 are arranged on the housing 100, and after the support leg 1 is installed, the abutment between the support leg 1 and the placement surface can avoid the direct contact between the outer surface of the housing 100 and the placement surface. At the same time, the support leg 1 can also cover the structure in the placement slot 2, so the best position of the gate is selected in the placement slot 2. It should be noted that the gate in the placement slot 2 will remain a part that cannot be cut off, because the size of the placement slot 2 is relatively small, and it is difficult for tools to enter, and it is very time-consuming and laborious to cut the gate by hand. The residual gate 23 exists in the placement slot 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 slot 2, and after the support leg 1 is arranged in the placement slot 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 greater than the size of the residual gate 23, which can not only ensure the complete accommodation of the residual gate 23, but also still reserve part of the space for drainage after accommodating the residual gate 23.

[0115] With reference to Figure 1and Figures 8 to 14 As shown in the figure, the shell 100 can include a first shell part 101 and a second shell part 102, the first shell part 101 is rotationally connected with the second shell part 102, the first shell part 101 and the second shell part 102 can realize 0°-180° rotation, so that the shell 100 has a first state and a second state. When the shell 100 is in the first state, the angle between the first shell part 101 and the second shell part 102 is 0°, the first shell part 101 and the second shell part 102 are in a folded state (i.e. a storage state), so that the opening side of the first shell part 101 is engaged with the opening side of the second shell part 102. When the shell 100 is in the second state, the angle between the first shell part 101 and the second shell part 102 is 180°, the first shell part 101 and the second shell part 102 are in an unfolded state.

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

[0117] Among them, the shell 100 can reduce the storage volume after folding, and increase the clothes 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 by 180° and is rotated to the upper surface to become the upper appearance surface, but in the unfolded state (i.e. the clothes drying state), the outer side surface 110 of the bottom of the two shell parts is in contact with the placement surface. Therefore, both shell parts have drainage requirements, while considering the appearance requirements. The appearance surfaces of the two shell parts in this embodiment are provided with placement grooves 2 for placing the supporting legs 1, so that the drainage effect can be well guaranteed.

[0118] In some embodiments,

[0119] Reference Figures 1 to 14As shown, the electric appliance can be a clothes dryer, for example, a rotary folding clothes dryer. The housing 100 of the clothes dryer can include a first housing part 101 and a second housing part 102, which can rotate relative to each other, and can achieve a 0°-180° rotation. When the angle between the first housing part 101 and the second housing part 102 is rotated to 0°, the clothes dryer is in a storage state; when the first housing part 101 and the second housing part 102 are rotated to 180°, the clothes dryer is in an unfolded state. The outer surfaces of the first housing part 101 and the second housing part 102 are each provided with a support leg 1.

[0120] The first housing part 101 and the second housing part 102 are both appearance parts. Since each appearance surface of the first housing part 101 and the second housing part 102 can be seen by a user after the housing 100 is folded, in order to improve the appearance aesthetics, no sprue marks can be left on the appearance surface. In order to ensure that the outer side surface 110 of the bottom is not in direct contact with the ground in the unfolded state, the above-mentioned outer side surface 110 of the first housing part 101 and the second housing part 102 is provided with a plurality of placement grooves 2 of the support leg 1. After the support leg 1 is placed in the placement groove 2, the above-mentioned outer side surface 110 can be prevented from being in direct contact with the ground, and the support leg 1 can also cover the structure in the placement groove 2. Therefore, the best position for leaving a sprue mark can be selected in the placement groove 2.

[0121] The placement groove 2 can include a ring-shaped protrusion 122 part, a rib 21, a water leakage opening 50, and a residual sprue 23. Because the structure features provided in the support leg 1 require a certain height space, the ring-shaped protrusion 122 part 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, so as to ensure that a cavity for accommodating the support leg 1 is formed.

[0122] The placement groove 2 can include a plurality of ribs 21 distributed in the circumferential circle of the side surface of the placement groove 2. Because the inner side surface of the ring-shaped protrusion 122 part is in interference fit with the side surface of the support leg 1, it plays a fixing role on the support leg 1. The height of the interference here is just the height difference between the rib 21 and the ring-shaped protrusion 122 part. If the height of the rib 21 is consistent with the height of the ring-shaped protrusion 122 part, the support leg 1 cannot be inserted into the placement groove 2 and will be stopped by the rib 21. Therefore, the height of the rib 21 needs to be lower than that of the ring-shaped protrusion 122 part, so as to better ensure the installation of the support leg 1.

[0123] The water leakage hole 50 of the installation groove 2 communicates the inner cavity of the shell 100 with the installation groove 2. For the gate, because the installation groove 2 is submerged into the support leg 1, the gate of the inner side part of the annular protrusion 122 cannot follow the mold to exit, and a residual gate 23 is formed in the installation groove 2, which can be located at the center of the installation groove 2. It should be noted that the residual gate 23 does not have to be located at the center, but it is more appropriate to be located at the center. The residual gate 23 is located at the center because the whole machine is designed with multiple support legs 1. If the residual gate 23 is not located at the center, the avoidance space of the support leg 1 will also not be located at the center, and the production assembly will have directionality, which is equivalent to a structure preventing mistakes; if it is located at the center, it can be assembled randomly, improving the production efficiency.

[0124] The support leg 1 can be made of silica gel or rubber material and has a certain elasticity, and can include a reverse skirt 112, a protrusion 122, a flow guide hole 30, a drainage hole 40, and a containing cavity 10, etc. The reverse skirt 112 can be a rotating body with a triangular stepped cross section, which will compress and deform under stress. The containing cavity 10 is a cylindrical cavity located at the center of the support leg 1. The flow guide hole 30 is connected to the outside and the containing cavity 10. The drainage hole 40 is located at the bottom center of the support leg 1 and is connected to the containing cavity 10. The drainage hole 40 is not in direct contact with the ground and leaves a certain height from the ground. Around the bottom drainage hole 40, the distance from the center axis outward and the drainage hole 40 downward gradually decreases until it contacts the ground. Based on this, the four around the drainage hole 40 below form an umbrella-shaped cavity, i.e. a drainage cavity 60. The protrusions 122 are annularly distributed around the umbrella-shaped cavity and are in direct contact with the ground, and gaps are left between adjacent protrusions 122, thereby forming a drainage gap 20 between the support leg 1 and the ground.

[0125] It should be noted that the protrusions 122 are provided to support the support leg 1 and 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 leg 1 will be in direct contact with the ground, so that the water flowing from the center of the support leg 1 is trapped in the support leg 1 and is difficult to seep out from the four around, which is not conducive to the drainage of water from the inside of the shell 100 to the outside.

[0126] Wherein, after the support leg 1 is installed on the shell 100, the reverse buckle skirt 112 of the support leg 1 has interference with the rib 21 in the installation groove 2, and the support leg 1 is pressed by the rib 21 around the installation groove 2 due to the elasticity of the material of the support leg 1, so that the support leg 1 is not easy to be taken out of the installation groove 2. The accommodation cavity 10 of the support leg 1 is used to avoid the residual gate 23 of the shell 100, and one side of the accommodation cavity 10 is communicated with the flow guide hole 30 and the other side is communicated with the drainage hole 40. The diameter and depth of the accommodation cavity 10 are larger than those of the residual gate 23. The accommodation cavity 10 is communicated with the umbrella-shaped cavity through the drainage hole 40, and the flow guide hole 30 is communicated with the water leakage hole 50. Therefore, the water in the shell 100 is sequentially discharged to the outside through the water leakage hole 50, the flow guide hole 30, the accommodation cavity 10, the drainage hole 40, the drainage cavity 60 and the drainage gap 20.

[0127] Wherein, the support leg 1 can include an annular flange 1211, which is in contact with the annular protrusion 122 of the installation groove 2, covers the annular protrusion 122, and makes the annular protrusion 122 not directly contact the ground. The side surface of the main column body 111 of the support leg 1 has interference with the side surface of the rib 21 in the installation groove 2. The main column body 111 of the support leg 1 is pressed by the rib 21 in the installation groove 2 due to the elasticity of the material of the support leg 1, so that the support leg 1 is not easy to be taken out of the installation groove 2 after assembly. In addition, the end of the side surface of the main column body 111 of the support leg 1 (i.e. the side connected with the connecting column body 113) is designed as a C corner 1111, which facilitates the installation of the support leg 1 into the installation groove 2.

[0128] In this embodiment, through the support leg 1 and the installation groove 2 on the shell 100 as described above, after the support leg 1 is installed in the installation groove 2, not only the water infiltrated into the shell 100 during the operation of the clothes dryer can be discharged to the outside in time, but also the shell 100 does not need to be separately provided with a drainage hole 40, thereby avoiding the damage to the integrity and the appearance due to the opening of the appearance surface. At the same time, the support leg 1 also shields the residual gate 23 of the mold on the shell 100, which not only hides the unattractive residual gate 23, but also meets the drainage requirement, and makes the appearance surface not directly contact the ground, thereby avoiding the abrasion of the surface.

[0129] In addition, a flow guide structure can be arranged in the shell 100. If the flow guide structure is arranged, the position of the water flow from the outside should 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 clothes dryer. The water blocking rib 30021 can be arranged in the shell 100, and the water blocking rib 30021 and the side surface of the shell 100 form a water area 401 (such as the blue line area shown in Figure 12 The water area 401 includes the installation groove 2, which is convenient for drainage. The non-water area 402 has a heating element terminal and a main board, and the electric components are prevented from contacting water (as shown in Figure 12 ).

[0130] It should be noted that the shell 100 of the embodiment can be applied to a clothes dryer, and can also be applied to other electrical appliances, such as an indoor heater, a fan, etc.

[0131] In the embodiment, when the support leg 1 is arranged in the arrangement groove 2 at the bottom of the shell 100, the water leakage opening 50, the flow guide hole 30, the accommodation cavity 10, the drainage hole 40, and the drainage gap 20 on the arrangement groove 2 constitute a drainage channel at the bottom of the shell 100, so that water in the shell 100 can be drained in time. When the shell 100 is applied to an electrical appliance such as a clothes dryer, the water in the shell 100 can be drained in time through the cooperation of the support leg 1 and the arrangement groove 2, so that water accumulation in the shell 100 can be avoided, and electrical components in the electrical appliance can be well prevented from being in contact with water, so that electrical faults such as short circuit and electric shock can be avoided, not only the electrical appliance can be better protected, but also potential risks (such as electric shock accidents) to the personal safety of users can be reduced, and the use experience of users can be improved.
