Description

Technical Field

[0001] This utility model relates to the field of household appliances, specifically to a clothing processing device. Background Technology

[0002] During operation, the rotating drum of a washing machine or dryer may collide with the side panel of the machine body, which will significantly increase vibration and noise and affect the user experience. It is necessary to leave a safe collision distance between the drum and the side panel to avoid collision between the two.

[0003] However, in existing technologies, the safe collision range in the height direction is relatively small, and the risk of collision between the roller and the side panel still exists during the operation of the garment processing equipment. On the other hand, there is a need in this field to miniaturize garment processing equipment. How to balance providing a safe collision distance between the side panel and the roller with the miniaturization of the equipment is a technical problem that urgently needs to be solved. Utility Model Content

[0004] To address the above problems, this utility model provides a garment processing device that can effectively prevent the roller from colliding with the side plate, thereby reducing vibration and noise during operation, while also meeting the need for miniaturization of the overall size of the garment processing device.

[0005] One aspect of this utility model provides a garment processing device, comprising:

[0006] roller;

[0007] The housing includes a side plate located on at least one side of the roller. The side plate includes a flat portion and a protrusion. The protrusion extends directly from the flat portion in a direction away from the roller, and the projection of the roller's rotation axis onto the side plate lies within the protrusion.

[0008] Depending on the different load conditions of the clothes on the roller, the projection of the roller's rotation axis onto the side plate has a floating range, and the extension range of the protrusion in the height direction covers the floating range.

[0009] According to the above technical solution, the protrusion can provide a safe collision distance to avoid the roller, and at the same time provide a sufficient safe collision range in the height direction. It can effectively avoid the collision between the roller and the side plate under different clothing load conditions, thereby reducing the vibration and noise of the clothing processing equipment during operation, and making the clothing processing equipment operate more quietly and smoothly.

[0010] Optionally, multiple protrusions are spaced apart along the height direction, and the multiple protrusions correspond to the projection of the rotation axis of the roller covering different clothing load states on the side plate.

[0011] According to the above technical solution, the safe collision range of the roller can be guaranteed under different clothing load conditions; at the same time, multiple protrusions can improve the stiffness of the side plate and increase the first-order natural frequency, effectively enhancing the vibration suppression capability of the side plate.

[0012] Optionally, it also includes: an upper reinforcing strip and / or a lower reinforcing strip, respectively disposed on the upper or lower side of the protrusion along the height direction, the upper reinforcing strip and / or the lower reinforcing strip comprising a plurality of horizontally extending reinforcing strips arranged sequentially along the height direction.

[0013] According to the above technical solution, the strength of the side plate can be further enhanced, the first-order natural frequency can be increased, the vibration suppression capability of the side plate can be enhanced, and thus the vibration and noise of the clothing processing equipment during operation can be reduced.

[0014] Optionally, the perimeter of the reinforcing rib is rectangular, and the reinforcing rib has an arc surface that smoothly transitions from the perimeter to the center.

[0015] According to the above technical solution, the poor wall thickness uniformity caused by excessive stretching and extension of the reinforcing ribs can be avoided.

[0016] Optionally, adjacent reinforcing bars are connected to each other in the height direction.

[0017] According to the above technical solution, the number of reinforcing ribs can be guaranteed within a limited height, thereby further improving the strength of the side plate.

[0018] Optionally, the spacing between multiple protrusions is 0-15mm.

[0019] Optionally, the interval between the protrusion and the upper reinforcing strip is 0-20mm, and the interval between the protrusion and the lower reinforcing strip is 0-20mm.

[0020] Optionally, in the height direction, the interval between adjacent ribs is 0-7mm.

[0021] Optionally, the protrusion of the protrusion relative to the flat plate is greater than or equal to 2 mm.

[0022] The above technical solution ensures a safe collision distance for the rollers.

[0023] Optionally, the garment load state includes a standard state. When the roller is in the standard state, the projection of its rotation axis onto the side plate is the standard projection position. The width of the protrusion corresponding to the standard projection position along the height direction is greater than the width of other protrusions.

[0024] According to the above technical solution, corresponding to the standard projection position of the roller on the side plate when the clothing load is in the standard state, the width of the protrusion along the height direction is correspondingly increased, thereby effectively ensuring the safe collision range of the roller in the standard state.

[0025] Optionally, a deformable part is also provided, one end of which is connected to the flat plate part and the other end of which is connected to the protrusion part. The deformable part is an inclined surface or an arc surface.

[0026] According to the above technical solution, the strength of the ribs can be enhanced, and the risk of tensile and elongation cracking can be avoided.

[0027] Alternatively, the garment handling equipment may be a front-loading washing machine or a dryer. Attached Figure Description

Detailed Implementation

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] <First Implementation Method>

[0040] refer to Figure 1 This embodiment of a garment processing device 100 includes a drum 10 and a housing 20. The garment processing device 100 is a drum-type washing machine or a drum-type dryer. The housing 20 includes a side plate 200 located on at least one side of the drum 10.

[0041] refer to Figure 2 The side plate 200 includes a flat plate portion 201 and a protrusion portion 202. The protrusion portion 202 is formed by bending and extending directly from the flat plate portion 201 away from the roller 10. The projection of the rotation axis of the roller 10 on the side plate 200 is located inside the protrusion portion 202.

[0042] Specifically, the protrusion 202 protrudes away from the flat plate 201 in a direction away from the roller 10, forming a corresponding safety collision space. The safety collision space formed by the protrusion 202 can provide a safe collision distance for the roller 10 during operation. Furthermore, the projection of the rotation axis of the roller 10 onto the side plate 200 is located within the protrusion 202. During the operation of the garment processing equipment 100, the protrusion 202 can effectively prevent the outer peripheral surface of the roller 10 from contacting and colliding with the side plate 200, thereby reducing the vibration and noise during the operation of the garment processing equipment 100.

[0043] Meanwhile, the structural design of the side plate 200 alone can effectively prevent the roller 10 from colliding with the side plate 200, eliminating the need for other anti-collision structures and taking into account the need for miniaturization of the overall size of the garment processing equipment.

[0044] Depending on the different clothing load conditions of the roller 10, the projection of the rotation axis of the roller 10 onto the side plate 200 has a floating range, and the extension range of the protrusion 202 in the height direction covers the floating range.

[0045] Specifically, during the actual washing process, as the drum 10 rotates, the projection of the rotation axis of the drum 10 onto the side plate 200 will float in the height direction, and the floating range will vary depending on the load state of the clothes inside the drum 10.

[0046] refer to Figure 1The floating range includes the floating range A when the clothing load is in the standard state of clothing within the general weight range.

[0047] Specifically, the floating range A is the area where the outer periphery of the roller 10 is at its minimum height from the side plate 200 under the standard state, which is the area where the roller 10 and the side plate 200 are likely to collide under the standard state. By providing the protrusion 202 in the floating range A, it is possible to effectively avoid the collision between the roller 10 and the side plate 200 under the standard state.

[0048] When the clothing is under no load or light load, the floating range B is increased by extending upwards in the height direction.

[0049] Specifically, when the roller 10 deviates from the standard state and is under no-load or light-load conditions, the area that the roller 10 may reach in the height direction will extend upward accordingly. At this time, the floating range B is obtained based on the minimum height area between the outer circumference of the roller 10 and the side plate 200, the elastic coefficient of the hanging spring connected to the roller 10, and the weight of the roller 10. The possible collision area between the roller 10 and the side plate 200 will simultaneously include the floating range A and the floating range B. By providing protrusions 202 in both the floating range A and the floating range B, it is possible to ensure the strength of the side plate while avoiding collision between the roller 10 and the side plate 200 under no-load or light-load conditions.

[0050] When the clothing is fully loaded, the floating range C is increased by extending downwards in the height direction.

[0051] Specifically, when the roller 10 deviates from the standard state and is fully loaded with clothing, the area that the roller 10 may reach in the height direction will extend downward accordingly. At this time, the floating range C is obtained based on the minimum height area between the outer circumference of the roller 10 and the side plate 200, the elastic coefficient of the hanging spring connected to the roller 10, and the weight of the roller 10. The possible collision area between the roller 10 and the side plate 200 will simultaneously include the floating range A and the floating range C. By providing protrusions 202 in both the floating range A and the floating range C, it is possible to ensure the strength of the side plate while avoiding collision between the roller 10 and the side plate 200 under full load.

[0052] Therefore, the floating ranges A, B, and C effectively cover the areas where the roller 10 is prone to collide with the side plate 200 under different clothing load conditions. By extending the protrusion 202 in the height direction to cover the floating range, the safe collision range of the roller 10 under different clothing load conditions can be guaranteed, thereby effectively avoiding collisions between the roller 10 and the side plate 200.

[0053] Multiple protrusions 202 are spaced apart along the height direction, and the multiple protrusions 202 correspond to the projection of the rotation axis of the roller 10 covering different clothing load states on the side plate 200.

[0054] Specifically, by setting multiple protrusions 202 in the height direction, the safe collision range of the roller 10 can be guaranteed under different clothing load conditions; at the same time, the multiple outwardly protruding protrusions 202 can improve the stiffness of the side plate and increase the first natural frequency, which can effectively enhance the vibration suppression capability of the side plate 200, thereby reducing vibration and noise during operation, so that the clothing processing equipment 100 can operate more quietly and smoothly.

[0055] The clothing load state includes the standard state. When the roller 10 is in the standard state, the projection of its rotation axis on the side plate 200 is the standard projection position. The width of the protrusion corresponding to the standard projection position along the height direction is greater than the width of other protrusions.

[0056] Specifically, refer to Figure 2 and Figure 3 In this embodiment, the protrusion 202 is located in the middle of the side plate 200. There are three protrusions 202 in total, which are the upper protrusion 2021, the middle protrusion 2022 and the lower protrusion 2023 in the height direction. The width of the middle protrusion 2022 in the height direction is greater than the width of the upper protrusion 2021 and the lower protrusion 2023 in the height direction.

[0057] Furthermore, the clothing load state includes a standard state, which is the state in which the drum 10 contains clothing within a normal weight range and performs a regular washing and care mode. When the drum 10 is in the standard state, the projection of its rotation axis on the side plate 200 is the standard projection position, and the central protrusion 2022 covers the standard projection position. That is, when the clothing load state is in the standard state, the extension range of the central protrusion 2022 in the height direction covers the floating range of the projection of the rotation axis of the drum 10 on the side plate 200.

[0058] Therefore, the central protrusion 2022 has a sufficiently large width in the height direction. Under standard conditions, even if the roller 10 is loaded with clothes of different weights, the standard projection position of the rotation axis of the roller 10 on the side plate 200 can be kept within the central protrusion 2022, effectively ensuring the safe collision range of the roller 10 under different clothing loads under standard conditions.

[0059] Furthermore, the clothing load state also includes extreme states such as empty load, light load, and full load. In this embodiment, by providing an upper protrusion 2021 above and a lower protrusion 2023 below the central protrusion 2022, the projection floating range of the rotation axis of the roller 10 on the side plate 200 under extreme states can be extended accordingly, thereby effectively ensuring the safe collision range of the roller 10 under extreme states such as light load or full load.

[0060] refer to Figure 3 The side plate 200 is also provided with a deformable part 203, one end of which is connected to the flat plate part 201 and the other end is connected to the protrusion part 202. The deformable part 203 is a slope or arc surface. The deformable part 203 can strengthen the strength of the rib and avoid the risk of breakage due to stretching.

[0061] refer to Figure 2 and Figure 3 The side plate 200 also includes an upper reinforcing strip 204 and a lower reinforcing strip 205, which are respectively arranged on the upper or lower side of the protrusion 202 along the height direction. By providing the upper reinforcing strip 204 and the lower reinforcing strip 205, the strength of the side plate can be effectively improved. In some other embodiments, the upper reinforcing strip 204 and the lower reinforcing strip 205 may also be provided individually or not, and this utility model does not limit this.

[0062] In this embodiment, both the upper reinforcing strip 204 and the lower reinforcing strip 205 include multiple horizontally extending reinforcing strips 206 arranged sequentially along the height direction.

[0063] Specifically, the multiple horizontally extended ribs 206 can effectively enhance the stiffness of the side plate 200 and increase the first natural frequency, thereby further enhancing the vibration suppression capability of the side plate 200.

[0064] Further, refer to Figure 4 and Figure 5 The periphery of the rib 206 is rectangular, and the rib 206 has an arc surface that smoothly transitions from the periphery to the center. In addition, adjacent ribs 206 are connected to each other in the height direction.

[0065] refer to Figure 3 In this embodiment, the upper reinforcing strip 204 has four reinforcing ribs 206, and the lower reinforcing strip 205 has five reinforcing ribs 206. There are no gaps between the reinforcing ribs 206 that are flush with the flat plate 201. Adjacent reinforcing ribs 206 are connected to each other and have a smooth, gradual transition. This avoids excessive stretching of the reinforcing ribs, which could lead to poor wall thickness uniformity. Furthermore, it ensures that the number of reinforcing ribs 206 is sufficient within a limited height, thereby further improving the strength of the side plate.

[0066] In this embodiment, the interval between the upper protrusion 2021, the middle protrusion 2022 and the lower protrusion 2023 is 10mm, the interval between the upper protrusion 2021 and the upper reinforcing strip 204 is 10mm, the interval between the lower protrusion 2023 and the lower reinforcing strip 205 is 10mm, and the protrusion of the protrusion 202 relative to the flat plate 201 is greater than or equal to 2mm.

[0067] By arranging the upper protrusion 2021, the middle protrusion 2022, and the lower protrusion 2023 at intervals, and also at intervals with the upper rib strip 204 and the lower rib strip 205, the side plate 200 can be more easily manufactured while ensuring the safe collision range of the roller and the strength of the side plate. Furthermore, the protrusion amount of the protrusion 202 is greater than or equal to 2mm, effectively ensuring the safe collision distance of the roller.

[0068] refer to Figure 6 In some embodiments, the protrusions 202 can be individually arranged with zero spacing, resulting in a smoother transition between multiple protrusions 202. For example... Figure 6 As shown, the interval between the upper protrusion 2021, the middle protrusion 2022, and the lower protrusion 2023 is 0mm. Simultaneously, the positions of the upper reinforcing strip 204, the lower reinforcing strip 205, and the reinforcing rib 206 are adjusted. The interval between the upper protrusion 2021 and the upper reinforcing strip 204 is 1mm to 7mm; the interval between adjacent reinforcing ribs 206 in the upper reinforcing strip 204 is 1mm to 7mm; the interval between the lower protrusion 2023 and the lower reinforcing strip 205 is 1mm to 7mm; and the interval between adjacent reinforcing ribs 206 in the lower reinforcing strip 205 is 1mm to 7mm. The spacing between protrusions 202, between protrusions 202 and the upper / lower reinforcing strip 204 / 205, and between the reinforcing strips 206 of the upper / lower reinforcing strip 204 / 205 should not be too wide or too narrow. Too wide a spacing will result in a smaller number or width of protrusions 202 that can be installed. A spacing of 7mm or less is preferred. The side plate 200 of the above type has good strength.

[0069] refer to Figure 7 In some embodiments, the number of ribs 206 can be increased by compressing the width of the ribs 206 in the height direction. For example... Figure 7As shown, the upper reinforcing strip 204 has five reinforcing ribs 206, and the lower reinforcing strip 205 has seven reinforcing ribs 206. The interval between the lower protrusion 2023 and the lower reinforcing strip 205 is 1mm to 7mm, and the interval between adjacent reinforcing ribs 206 in the lower reinforcing strip 205 is also 1mm to 7mm. Meanwhile, the interval between the upper protrusion 2021, the middle protrusion 2022, and the lower protrusion 2023 is 10mm, the interval between the upper protrusion 2021 and the upper reinforcing strip 204 is 1mm to 7mm, and the interval between adjacent reinforcing ribs 206 in the upper reinforcing strip 204 is also 1mm to 7mm. The side plate 200 of the above configuration has a high first-order natural frequency and high strength.

[0070] <Second Implementation Method>

[0071] In this embodiment, based on the clothing processing device 100 in the first embodiment, the protrusion 202 in the side plate 200 is configured differently from the upper pressure rib 204 and the lower pressure rib 205.

[0072] refer to Figure 8 In this embodiment, the interval between the upper protrusion 2021, the middle protrusion 2022 and the lower protrusion 2023 is 0mm, the interval between the upper protrusion 2021 and the upper reinforcing strip 204 is 0mm, and the interval between the lower protrusion 2023 and the lower reinforcing strip 205 is 0mm.

[0073] By setting multiple protrusions 202 with zero intervals between them and between the protrusions 202 and the upper reinforcing strip 204 / lower reinforcing strip 205, the transition between the multiple protrusions 202 and between the protrusions 202 and the upper reinforcing strip 204 / lower reinforcing strip 205 can be smoother, improving the uniformity of wall thickness. Furthermore, the number and width of the protrusions 202 and the reinforcing strips 206 are taken into account, further improving the strength of the side plate.

[0074] <Third Implementation Method>

[0075] In this embodiment, based on the clothing processing device 100 in the first embodiment, the protrusion 202, the upper reinforcing strip 204, and the lower reinforcing strip 205 in the side plate 200 are configured differently.

[0076] refer to Figure 9 In this embodiment, only one protrusion 202 is provided. The extension range of the protrusion 202 in the height direction can cover the projection floating range of the rotation axis of the roller 10 on the side plate 200 under different clothing load conditions. Thus, even with a single protrusion 202, the safe collision range of the roller 10 under different clothing load conditions is also guaranteed.

[0077] Furthermore, the interval between the protrusion 202 and the upper reinforcing strip 204 is 20mm, and the interval between the protrusion 202 and the lower reinforcing strip 205 is 20mm. The upper reinforcing strip 204 has three reinforcing ribs 206, and the interval between adjacent reinforcing ribs 206 in the upper reinforcing strip 204 is 0mm. The lower reinforcing strip 205 has four reinforcing ribs 206, and the interval between adjacent reinforcing ribs 206 in the lower reinforcing strip 205 is 0mm.

[0078] In this embodiment, a single protrusion 202 is sufficient to ensure the safe collision range of the roller 10 under different clothing load conditions, resulting in a simpler side panel structure design and easier fabrication. Furthermore, the ribs 206 in both the upper and lower rib strips 204 and 205 are arranged with zero spacing, and the ribs 206 transition smoothly and gradually. This avoids excessive stretching of the ribs leading to poor wall thickness uniformity while ensuring a limited number of ribs 206 within a certain height, thereby guaranteeing the strength of the side panel.

[0079] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
