Description

Technical Field

[0001] The utility model relates to the technical field of washing equipment, and specifically provides a window pad used for washing equipment and the washing equipment. Background Art

[0002] Existing drum washing machines are usually provided with a window gasket between the front plate of the casing and the outer drum to prevent water in the outer drum from leaking into the washing machine through the gap between the outer drum and the casing. When the door is closed, the door will squeeze the window gasket, thereby sealing the gap between the door and the front plate of the casing to prevent washing water from leaking out of the washing machine during the washing process.

[0003] Existing window gaskets are usually provided with a Z-shaped telescopic part, which includes an upper wall, a lower wall, and a connecting wall arranged between the upper wall and the lower wall. During the rotation of the drum, when the clothes in the inner drum are unbalanced and the rotation eccentricity is large, the outer drum will drive the telescopic part to vibrate forward and backward and / or left and right. In order to ensure the anti-bending performance of the telescopic part during the vibration process, the existing window gasket will set the upper wall and the lower wall of the telescopic part to be relatively long. The longer upper wall and the lower wall can certainly provide more deformation, but such a setting will increase the thickness of the whole machine, thereby making it difficult to embed and install the machine. Therefore, how to reduce the thickness of the whole machine as much as possible while ensuring the anti-bending performance of the window gasket has become a technical problem that needs to be solved urgently in this field.

[0004] In view of this, the art needs a new window pad for a washing device and a washing device to solve the existing problems. Utility Model Content

[0008] In a specific embodiment of the window mat for a washing device, the overlapping dimension of the projections of the upper wall and the lower wall in the horizontal direction is less than 1 / 2 of the length of the shorter one of the upper wall and the lower wall.

[0009] In a specific embodiment of the window mat for washing equipment, there is a gap between the upper wall and the first containing portion, and the width of the gap is 25% to 75% of the longer length of the upper wall and the lower wall.

[0010] In a specific embodiment of the window mat for washing equipment, a water permeable hole is provided on the first containing portion, and a water passing hole is provided on the outer cylinder. The water permeable hole and the water passing hole are arranged correspondingly, and the diameter of the water passing hole is greater than or equal to the diameter of the water permeable hole, so that the accumulated water at the connection between the first containing portion and the outer cylinder can be discharged through the water permeable hole and the water passing hole.

[0011] In a specific embodiment of the window pad for a washing device, the thickness of the lower wall gradually increases from the connecting wall toward the first containing portion, and / or the thickness of the upper wall gradually increases from the connecting wall toward the second containing portion.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0027] First, a window gasket of a conventional drum washing machine will be described.

[0028] like Figure 1 , Figure 3 , Figure 4As shown, the existing drum washing machine 1 includes a front plate 13 and a box body, and an outer drum 12 is installed in the body through a suspension device. The outer drum 12 is used to hold water and detergent. An inner drum 14 covered with water holes is rotatably arranged in the outer drum 12. The inner drum 14 is used to hold clothes. The rear part of the inner drum 14 is connected to a motor 16 after passing through the outer drum 12 through an axis. The motor 16 is used to drive the inner drum 14 to rotate at different speeds to achieve operations such as beating, washing and dehydrating clothes. A drain pipe 17 is also provided at the bottom of the outer drum 12. The drain pipe 17 extends outside the washing machine. A drain pump 15 is provided at the bottom of the drain pipe 17 to drive the waste water of washing to be discharged outside the washing machine. Openings are provided in the middle of the front plate 13, the front of the outer drum 12 and the inner drum 14 for taking in and putting clothes. A door body 132 is also hingedly provided on the front plate 13 to close the above opening to prevent clothes and / or washing water from spilling out of the above opening. In order to facilitate the user to observe the operating state of the inner drum 14 of the washing machine, a transparent observation window is usually provided on the door body 132 for the user to observe. In order to prevent the washing water from flowing out of the opening of the outer drum 12 into the inner space of the washing machine outside the outer drum 12 when the water level is high, a window gasket 11 is usually provided at the opening of the outer drum 12 and the opening of the front plate 13. When the door body 132 is closed, the observation window on the door body 132 will press the window gasket 11 on the front plate 13, thereby sealing the space inside the outer drum 12 and preventing the washing water from leaking to the outside of the washing machine. The window pad 11 is usually provided with a telescopic portion with a Z-shaped cross section, and the Z-shaped telescopic portion includes an upper wall 1111, a lower wall 1113, and a connecting wall 1112 arranged between the upper wall 1111 and the lower wall 1113. During the rotation of the drum, when the clothes in the inner drum 14 are unbalanced and the rotation eccentricity is large, the outer drum 12 will drive the Z-shaped telescopic portion (especially the lower wall 1113 directly connected to the outer drum 12) to vibrate forward and backward or left and right. In order to enhance the anti-bending performance of the Z-shaped telescopic portion during the vibration process, the existing window pad 11 will connect the upper wall 1111 and the lower wall 1113 of the Z-shaped telescopic portion. 1113 is set to be relatively long. Although this increases the deformation of the upper wall 1111 and the lower wall 1113 and improves its bending resistance, the increase in the length of the upper wall 1111 and the lower wall 1113 will increase the thickness of the entire machine, making it difficult to embed and install the machine, affecting the user experience. If the length of the upper wall 1111 and the lower wall 1113 is reduced for the convenience of installation, the upper wall 1111 and the lower wall 1113 (especially the lower wall 1113) will not deform enough, resulting in excessive force and even fatigue fracture. For this reason, the utility model proposes the following technical solution.

[0029] like Figure 1-Figure 3As shown, in order to solve the problem that the window gasket 11 of the existing drum washing machine 1 cannot reduce the thickness of the whole machine while ensuring the bending resistance of the window gasket 11, resulting in inconvenience in the embedded installation of the washing machine, the drum washing machine 1 of the utility model includes an outer drum 12 and a front plate 13, a door body 132 is provided on the front plate 13, the window gasket 11 is arranged between the door body 132 and the outer drum 12, the window gasket 11 includes a telescopic part 111, the telescopic part 111 includes an upper wall 1111, a connecting wall 1112 and a lower wall 1113 connected in sequence, the connecting wall 1112 is provided with reciprocatingly bent folds 11121, and the telescopic part 111 can achieve telescoping through the reciprocatingly bent folds 11121. The outer tube 12 is provided with a tube edge 121, and the window gasket 11 further includes a first containing portion 112, which includes an upper containing wall 1122 and a lower containing wall 1123. The upper containing wall 1122 is directly sleeved inside the tube edge 121 of the outer tube 12, and the lower containing wall 1123 is connected to the lower wall 1113 of the telescopic portion 111 and sleeved outside the tube edge 121 of the outer tube 12 to achieve the connection between the outer tube 12 and the lower wall 1113 of the telescopic portion 111. The front plate 13 is provided with a flange 131, and the window gasket 11 further includes a second containing portion 113, which is connected to the upper wall 1111 of the telescopic portion 111 and sleeved on the flange 131 of the front plate 13 to achieve the connection between the front plate 13 and the upper wall 1111 of the telescopic portion 111. The window gasket 11 further includes a sealing portion 114 , which is connected to the second containing portion 113 and / or the upper wall 1111 of the telescopic portion 111 , and can abut against the door body 132 to achieve sealing of the connection between the window gasket 11 and the door body 132 .

[0030] In the case of adopting the above embodiment, the outer drum 12 is connected to the lower wall 1113 of the telescopic part 111 by sleeve-mounting the first containing part 112 on the drum edge 121 of the outer drum 12, and the front plate 13 is connected to the upper wall 1111 of the telescopic part 111 by sleeve-mounting the second containing part 113 on the flange 131 of the front plate 13, thereby realizing the installation connection between the telescopic part 111, the front plate 13 and the outer drum 12. During the operation of the drum washing machine 1 of the utility model, the operation of the inner drum 14 generates vibration, which is transmitted to the outer drum 12 and acts on the telescopic part 111 of the window pad 11 through the outer drum 12. Since the lower wall 1113 of the telescopic portion 111 is connected to the outer tube 12 through the lower containing wall 1123 of the first containing portion 112, when the vibration is transmitted to the telescopic portion 111 of the window pad 11, it first reaches the lower wall 1113, then passes through the connecting wall 1112 and the upper wall 1111 in sequence and finally reaches the connection between the second containing portion 113 and the flange 131 of the front plate 13. Since spring-like reciprocating folds 11121 are provided on the connecting wall 1112 of the telescopic part 111, the reciprocating folds 11121 will vibrate by deformation to reduce the deformation of the lower wall 1113 and the upper wall 1111, thereby avoiding large pulling deformation of the upper wall 1111 and the lower wall 1113, and improving the bending resistance of the telescopic part 111. At the same time, since the reciprocating folds 11121 are arranged between the upper wall 1111 and the lower wall 1113 in the vertical direction, the thickness of the whole machine will not be increased, thereby solving the problem that the window pad 11 of the existing drum washing machine 1 cannot reduce the thickness of the whole machine while ensuring the bending resistance of the window pad 11, resulting in inconvenience in the embedded installation of the washing machine.

[0031] In addition, the above-mentioned solution of sleeve-mounting the first containing part 112 and the second containing part 113 on the tube edge 121 of the outer drum 12 and the flange 131 of the front plate 13 respectively can not only ensure the tightness of the installation connection between the telescopic part 111 and the front plate 13 and the outer drum 12, but also achieve the purpose of convenient disassembly and assembly, and easy maintenance and replacement. In addition, by setting the sealing part 114, when the door body 132 of the washing machine is closed, the sealing part 114 can abut against the door body 132, thereby forming a sealing ring between the window pad 11 and the door body 132 (the figure shows a cross-sectional view of the drum washing machine 1, and the window pad 11 is actually a ring structure), so as to prevent the washing water from splashing out from the gap between the window pad 11 and the door body 132 and reducing the user's experience.

[0032] Furthermore, in a possible embodiment, those skilled in the art may also arrange elastic fasteners (such as elastic hoop or elastic buckle, etc.) on the periphery of the connection between the first containing portion 112 and the outer tube 12 tube edge 121, and may also arrange the same or similar elastic fasteners on the periphery of the connection between the second containing portion 113 and the flange 131, so as to further ensure the stability of the connection structure between the telescopic portion 111 and the front plate 13 and the outer tube 12, and reduce the risk of the connection becoming detached.

[0033] Furthermore, in a possible embodiment, the overlapping dimension of the projections of the upper wall 1111 and the lower wall 1113 in the horizontal direction is less than 1 / 2 of the shorter length of the upper wall 1111 and the lower wall 1113, and the thickness of the lower wall 1113 gradually increases from the connecting wall 1112 to the direction of the first containing portion 112, and the thickness of the upper wall 1111 gradually increases from the connecting wall 1112 to the direction of the second containing portion 113.

[0034] As mentioned above, in order to enhance the bending resistance of the telescopic portion 111, the existing window pad 11 chooses to set the upper wall 1111 and the lower wall 1113 of the telescopic portion 111 to be relatively long. This will bring about a problem, that is, during the vibration of the telescopic portion 111, the lower wall 1113 will be pulled greatly while the connecting wall 1112 will be pulled only a small amount, which will cause the connection between the lower wall 1113 and the first containing portion 112 to be easily broken. In view of this, the present embodiment is proposed. In the case of adopting this embodiment, by setting the overlapping size of the projections of the upper wall 1111 and the lower wall 1113 in the horizontal direction to be less than 1 / 2 of the shorter length of the upper wall 1111 and the lower wall 1113, the length of the upper wall 1111 and the lower wall 1113 is limited to avoid being too long, and at the same time, by increasing the thickness of the connection between the lower wall 1113 and the first containing portion 112, the connection strength between the lower wall 1113 and the first containing portion 112 is strengthened, so that the upper wall 1111 and the lower wall 1113 can meet the anti-bending performance without causing the bending amplitude of the connection between the lower wall 1113 and the first containing portion 112 to be too large, and appropriately increase the pulling amplitude of the connection between the lower wall 1113 and the connecting wall 1112, so that the entire telescopic portion 111 can have continuous and uniform deformation, avoiding long-term large-amplitude bending and fatigue fracture at the connection between the lower wall 1113 and the first containing portion 112. In addition, those skilled in the art may also selectively increase the thickness of the connection between the upper wall 1111 and the second containing portion 113 according to actual needs, and all of these are within the protection scope of the present utility model.

[0035] In a possible embodiment, there is a gap 115 between the upper wall 1111 and the first containing portion 112, and the width of the gap 115 is 25% to 75% of the longer length of the upper wall 1111 and the lower wall 1113. A water permeable hole 1121 is provided on the first containing portion 112, and a water through hole 122 is provided on the outer cylinder 12. The water permeable hole 1121 and the water through hole 122 are provided correspondingly, and the diameter of the water through hole 122 is greater than or equal to the diameter of the water permeable hole 1121, so that the accumulated water at the connection between the first containing portion 112 and the outer cylinder 12 can be discharged through the water permeable hole 1121 and the water through hole 122.

[0036] like Figure 1-Figure 3 As shown, a chamber 116 is formed between the first containing portion 112 and the telescopic portion 111, and a gap 115 is present at the top of the chamber 116, namely, between the upper wall 1111 and the upper containing wall 1122. In the existing window pad 11, the gap 115 is too small. When the telescopic portion 111 vibrates, the upper wall 1111 and the upper containing wall 1122 are prone to friction, which may cause wear and leakage over time. During washing, the upper wall 1111 and the upper containing wall 1122 often clamp the clothes being washed when they are close to each other, causing pulling or damage to the clothes. At the same time, a too small gap 115 is not conducive to the evaporation of moisture inside the chamber 116, which may easily breed mold. In the case of adopting this embodiment, by setting the width of the gap 115 between the upper wall 1111 and the first containing part 112 to 25% to 75% of the longer length of the upper wall 1111 and the lower wall 1113, the width range of the gap 115 is limited, thereby avoiding the friction between the upper wall 1111 and the upper containing wall 1122 or even the situation of cloth being caught, and at the same time, the wider gap 115 is also conducive to the discharge of moisture inside the chamber 116, avoiding the breeding of mold. In addition, by setting the water-permeable holes 1121 and the water-passing holes 122 on the first containing part 112 and the outer cylinder 12, it is conducive to the discharge of the accumulated water in the chamber 116, further ensuring the dryness of the inside of the chamber 116. It can be understood by those skilled in the art that the number of the water-permeable holes 1121 and the water-passing holes 122 can be adjusted according to actual needs, and these changes do not exceed the protection scope of the present utility model.

[0037] like Figure 1-Figure 3 As shown, in a possible embodiment, the connection inflection point of the reciprocatingly curved folds 11121 is an arc, and the thickness at the connection inflection point is greater than the thickness of other parts on the connecting wall 1112, and the thickness at the connection inflection point is less than or equal to the maximum thickness of the upper wall 1111 and / or the lower wall 1113.

[0038] The advantages of the above embodiment are: since the connection inflection point is the area with the largest deformation amplitude on the connection wall 1112, therefore, by setting the thickness at the connection inflection point to be greater than the thickness of other parts of the connection wall 1112, the local hardness and strength can be increased to reduce the deformation amplitude, thereby increasing the bending life of the connection inflection point, and at the same time, the entire connection wall 1112 can be stretched evenly to maintain the overall life consistent without causing local damage. Thickening at this point can also increase the elasticity of the entire telescopic part 111, and better adapt to the vibration of the outer tube 12. At the same time, the thickness at the connection inflection point should not be too large to cause excessive bending strength, so the thickness at the connection inflection point should be set to be less than or equal to the maximum thickness of the upper wall 1111 and / or the lower wall 1113. The window gasket 11 structure set in this way has better telescopic performance than the traditional window gasket 11 when the low-temperature rubber hardens.

[0039] like Figure 1-Figure 3 As shown, in a possible embodiment, along the direction from the door body 132 to the outer cylinder 12, the lower wall 1113 and the upper wall 1111 have a first angle α and a second angle β that are inclined downward to the horizontal plane respectively, and there is a third angle γ between the reciprocating folds 11121 on the connecting wall 1112 and the horizontal plane, wherein γ>α≥β.

[0040] In the case of adopting the above embodiment, since it is inevitable that a small amount of washing water will splash onto the telescopic part 111 of the window pad 11 during the washing process, a downward inclined angle is set between the reciprocating folds 11121 of the lower wall 1113, the upper wall 1111 and the connecting wall 1112 and the horizontal plane, which facilitates the washing water to flow down from the upper wall 1111, the connecting wall 1112 and the lower wall 1113 and be discharged through the water permeable hole 1121 and the water through hole 122, thereby avoiding the growth of bacteria in the chamber 116. It is also worth mentioning that since the lower wall 1113 is located lower than the upper wall 1111 and is at the bottom of the chamber 116, the sizes of the first angle and the second angle are set to α≥β, so that the washing water in the chamber 116 can be more easily and completely discharged, thereby making the interior of the chamber 116 drier and avoiding the breeding of bacteria. The upper wall 1111 is closer to the machine door, and after washing is completed, the machine door can be opened to directly air-dry the upper wall 1111. In order to make it more convenient to throw clothes into the washing machine, the lowest point of the upper wall 1111 should be as flush as possible with the top of the upper containing wall 1122, so the inclination angle of the upper wall 1111 should not be too large, as long as it can meet the drainage requirements. Since the window gasket 11 itself is an annular structure, the upper wall 1111 and the lower wall 1113 are also annular structures. In this way, the space enclosed by the upper wall 1111 and the lower wall 1113 is a truncated cone-shaped space with a certain taper. Since the first angle α is greater than or equal to the second angle β, the taper of the truncated cone-shaped space enclosed by the lower wall 1113 is larger. In addition, regarding the third angle γ, since there are reciprocating folds 11121 on the connecting wall 1112, it is easier for dirt and residual water to be hidden between the folds 11121 and 11121. Therefore, the third angle γ is set to γ>α≥β, thereby reducing the possibility of dirt and residual water between the folds 11121 and 11121.

[0041] It should be noted that the above-mentioned implementation mode is only used to illustrate the principle of the utility model, and is not intended to limit the protection scope of the utility model. Without departing from the principle of the utility model, those skilled in the art can adjust the above-mentioned structure so that the utility model can be applied to more specific application scenarios.

[0042] In addition, the utility model also provides a washing device, which comprises the window pad 11 for washing device mentioned in any one of the above embodiments.

[0043] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
