Description

Technical Field

[0001] The invention belongs to the technical field of washing machines, and particularly relates to a washing machine water box and a washing machine. Background Art

[0002] The detergent box is a structure in the washing machine that holds detergent. The detergent box is used to store powdered and liquid detergents, such as washing powder, liquid detergent, bleach, softener, etc. When the washing machine is working, the user must first open the drawer, put in various types of detergents, and then close the drawer. The water inlet valve starts to flow water into the washing box and flush the detergent into the inner barrel.

[0003] The water box of the pulsator washing machine is mainly divided into two categories: automatic delivery type and pull-out type, among which the pull-out type water box is used in many product models. The pull-out type water box has two working conditions. First, pull the detergent box to the appropriate position and then pour the detergent; second, push the detergent box back to the initial position, and then the corresponding washing operation can be performed. The detergent box needs to be cleaned regularly, so it is set that the detergent box can be pulled out when the user pulls out the detergent box. At present, there are problems in the process of pulling out the detergent box: first, the user experience of pulling out is general, the limit of the drawer of the detergent box is not enough, resulting in the drawer shaking left and right after being pulled out, and at the same time, because the detergent box components and drawers are generally made of engineering plastics, the plastic will deform after a long time, resulting in the drawer cannot be pulled out and closed normally, or even if it can be pulled out, it is very sluggish and stiff, which seriously affects the user's experience and the quality grade of the washing machine; second, when the detergent box is pulled out to the state of pouring detergent, that is, when the detergent box is normally opened and pulled out, it is easy to pull out the entire detergent box, causing many inconveniences to the user. Summary of the invention

[0004] In view of the above problems existing in the prior art, the present invention provides a washing machine water box, which is provided with a supporting roller component to ensure that the detergent box can be pulled out smoothly and moved steadily.

[0005] In order to achieve the above technical objectives, the present invention adopts the following technical solutions:

[0045] See also Figure 1-Figure 15 , is an embodiment of the washing machine water box proposed by the present invention, a washing machine water box 10 comprises a water box body 1, a detergent box 2 which can be pulled out and is located in the water box body 1, before the washing machine starts washing, the detergent box 2 is pulled out and detergent is added into the detergent box 2; a supporting roller component 3 is provided on the water box body 1, and the supporting roller component 3 has two rollers 31 and 32 arranged on the left and right, and a vertically arranged first flange 23 is provided on the side wall of the detergent box 2, and the axes of the two rollers 31 and 32 are arranged vertically; the first flange 23 cooperates with the two rollers 31 and 32 to achieve the left and right direction limitation of the detergent box 2 during the pulling process, and the first flange 23 is located between the two rollers 31 and 32. During the pulling process of the detergent box 2, the first flange 23 rolls in contact with the two rollers 31 and 32.

[0046] In this embodiment, by providing a supporting roller component 3, the first flange 23 is located between the two rollers 31 and 32, so that the detergent box 2 is limited in the left and right directions during the pulling process. During the pulling process of the detergent box 2, the roller and the first flange 23 are in rolling contact, which is beneficial to reduce friction and make the pulling effortless. In addition, the first flange 23 is limited in the left and right directions, which avoids the shaking of the detergent box 2 in the left and right directions, and is beneficial to the smooth movement of the detergent box 2 during the pulling process.

[0047] See also Figure 6 and Figure 7 As shown, the supporting roller component 3 also has two supporting legs 33 and 34 for supporting the two rollers 31 and 32 respectively; by providing the two supporting legs 33 and 34, the rollers can have a certain movement in the left and right directions through the deformation of the supporting legs when subjected to force, and can be reset, so that the first flange 23 can have a certain deflection in the left and right directions to avoid the detergent box from getting stuck when being pulled out, and the first flange 23 is reset under the push of the reset force of the supporting legs, that is, the supporting roller component 3 has the function of correcting the deflection of the first flange 23 in the left and right directions, or the supporting roller component 3 has the function of correcting the deviation in the left and right directions, which is conducive to the smooth pulling of the detergent box 2.

[0048] The axes of the two rollers 31 and 32 are parallel, and the two rollers 31 and 32 are arranged side by side. The plane where the axes of the two rollers 31 and 32 are located is perpendicular to the first flange 23, and the first flange 23 is arranged vertically; it is ensured that during the drawing and pulling process of the detergent box 2, the first flange 23 rolls and contacts with the two rollers 31 and 32 to correct. It is preferred to set two left and right supporting roller components 3, which respectively cooperate with the first flange 23 on the left and right side walls of the detergent box 2, which is more conducive to preventing the detergent box from shaking left and right during the drawing and pulling process, and increasing stability.

[0049] See also Figure 8 As shown, the two supporting legs are a first supporting leg 33 close to the detergent box 2 and a second supporting leg 34 far from the detergent box 2, wherein the first supporting leg 33 is provided with a first roller 31, and the second supporting leg 34 is provided with a second roller 32; wherein the second supporting leg 34 has a curved support portion 341 and a second roller mounting portion 342 located at the upper end of the curved support portion 341. The second roller mounting portion 342 is vertically arranged, and the curved support portion 341 is arranged to improve the force deformation capacity of the second supporting leg 34 in the left and right directions, and to facilitate resetting.

[0050] As for the cooperation between the first flange 23 and the two rollers 31 and 32, the spacing between the two rollers 31 and 32 is set to match the thickness of the first flange 23. The first roller 31 and the second roller 32 can be set to be pressed against the first flange 23, that is, the spacing between the two rollers 31 and 32 is smaller than the thickness of the first flange 23; or the spacing between the two rollers 31 and 32 can be equal to or slightly larger than the thickness of the first flange 23, that is, in an ideal situation, the two rollers have no pressure on the first flange 23 of the detergent box, but in the process of pulling out the detergent box, it is impossible for the detergent box 2 to have no deviation in the left and right directions by itself. After a slight deviation, there is pressure between the first flange 23 and the rollers and correction is performed, and rolling contact is made; or only the second roller 32 can be set to be pressed against the first flange 23.

[0051] See also Fig.10 and Fig.11 As shown, a first limiting protrusion 24 is provided at the rear end of the first flange 23, protruding outward, that is, outward in the direction away from the center line of the detergent box 2. The first limiting protrusion 24 cooperates with the supporting roller component 3 to limit the separation of the detergent box 2 from the water box body 1; when the pulling force applied to the detergent box 2 is greater than the resistance encountered by the first limiting protrusion 24 through the supporting roller component 3, the detergent box 2 separates from the water box body 1. Since the detergent box 2 is provided with supporting roller components 3 in the left and right directions, and the first limiting protrusion 24 protrudes outward, when the first limiting protrusion 24 reaches the supporting roller component 3, it is stopped by the second roller 32. Only when sufficient pulling force is applied to the detergent box 2, the first limiting protrusion 24 squeezes the second roller 32 outward, pushing the second supporting leg 34 to deform outward, and the second roller 32 applies a large pressure inward to the first limiting protrusion 24, so that the first limiting protrusion 24 has a large friction force, and applies sufficient pulling force to the detergent box 2, so that the detergent box 2 is separated from the water box body 1; it is ensured that the pulling force required when the detergent box 2 is normally pulled out to add detergent is much smaller than the force required to separate the detergent box 2; two first limiting protrusions 24 are provided on the left and right of the detergent box 2. It is preferably arranged that the detergent box 2 can be separated only when the pulling force applied to the detergent box 2 is greater than or equal to 40N. This requires setting the protrusion size of the first limiting protrusion 24 and the pressure generated by the outer deformation of the second supporting leg 34. It is preferred to set the first limiting protrusion 24 as an elastic sheet, so it is also necessary to consider the elastic deformation of the first limiting protrusion 24 itself. By setting the first limiting protrusion 24 to cooperate with the supporting roller component 3, the separation of the detergent box 2 and the water box body 1 is limited, and the detergent box 2 is prevented from falling out when the detergent box 2 is normally pulled out, which is conducive to the convenience of operation.

[0052] See also Figure 2 and Fig.11As shown, a second limiting protrusion 25 is also provided on the first flange 23, which is raised in a direction away from the detergent box 2. The second limiting protrusion 25 cooperates with the supporting roller component 3 to limit the detergent box 2 to be in the pulled-out state, that is, to limit the detergent box to be normally pulled out to add detergent. By setting the second limiting protrusion 25 to cooperate with the supporting roller component 3, when the detergent box 2 reaches the pulled-out state, the second limiting protrusion 25 reaches the second roller 32 of the supporting roller component 3, and the second roller 32 blocks the second limiting protrusion 25. Under the pulling force of normal pulling, the detergent box 2 will stop opening when the second roller 32 blocks the second limiting protrusion 25, that is, it reaches the state of pulling out to add detergent. Preferably, the second limiting protrusion 25 is located in front of the first limiting protrusion 24, and the protruding size of the second limiting protrusion 25 is smaller than the protruding size of the first limiting protrusion 24, that is, the pulling force required for the second limiting protrusion 25 to support the roller component 3 is smaller than the pulling force required for the first limiting protrusion 24 to support the roller component 3.

[0053] The first limiting protrusion 24 and the second limiting protrusion 25 are both convex outwards, and cooperate with the second roller 32 to achieve limiting. When the first limiting protrusion 24 and the second limiting protrusion 25 pass through the second roller 32, the second support leg 34 is pushed outwards and deformed outwards; while the first support leg 33 is deformed very little in the inward and outward directions. The curved support portion 341 has an outward extension section 3411 extending upwards and away from the first support leg 33, and an inner extension section 3412 extending upwards and close to the first support leg 33 along the upper end of the outward extension section 3411. The provision of the outward extension section 3411 and the inner extension section 3412 is conducive to the excellent deformation and reset ability of the second support leg 34.

[0054] See also Figure 8 and Fig.10 As shown, the first support leg 33 has a straight column support portion 331 and a first roller mounting portion 332 located at the upper end of the straight column support portion 331. The straight column support portion 331 is a tapered column that is thicker at the bottom and thinner at the top, or a column that is the same thickness at the top and bottom. By providing the first support leg 33 with a straight column support portion, it is beneficial to ensure the support capacity of the first support leg 31 and avoid deformation of the first support leg 33. The support roller component 3 has a mounting portion 35 located at the lower part, and the first support leg 33 and the second support leg 34 are formed by extending upward along the mounting portion 35. An arc-shaped connecting surface 351 is provided at the upper end of the mounting portion 35, which is inclined downward from the first support leg 33 and toward the direction of the second support leg 34. The arc-shaped connecting surface 351 is located between the first support leg 33 and the second support leg 34, which is beneficial to form a favorable support for the first support leg 33 and the second support leg 34.

[0055] See also Fig.12 and Fig.13As shown, the water box body 1 has two left and right body side walls 11, and a guide groove 12 with an opening facing upward is provided at the upper end of the body side wall 11; during the process of pulling out the detergent box 2, the first flange 23 moves forward and backward in the guide groove 12; a second flange 22 extending away from the detergent box is provided at the upper end of the side wall 21 of the detergent box 2, and the outer side of the second flange 22 is folded downward to form the first flange 23. The second flange 22 is placed on the top of the side wall of the guide groove 12 close to the detergent box, or in other words, the top of the inner side wall of the guide groove 12 supports the lower end surface of the second flange 22; by providing the guide groove 12, it is beneficial to limit the detergent box 2 and pull it out smoothly.

[0056] A raised positioning block 121 is provided on the inner wall of the guide groove 12 away from the detergent box. When the detergent box 2 is closed in place, the first limiting protrusion 24 engages with the positioning block 121. The first limiting protrusion 24 also cooperates with the positioning block 121 to limit the detergent box 2 from being closed in place.

[0057] See also Figure 3 and Figure 4 As shown, the water box 10 also includes a box cover 4 buckled on the upper end of the water box body 1, and a third limit protrusion 26 protruding upward is provided on the second flange 22. The third limit protrusion 26 cooperates with the stop block extending downward from the upper end of the box cover 4 to limit the detergent box 2 to be in the pulled-out state. In this way, the detergent box has two limits on each side when it is in the pulled-out state. One is that the second limit protrusion 25 cooperates with the supporting roller component 3 to limit the detergent box 2 to be in the pulled-out state; the other is that the third limit protrusion 26 cooperates with the stop block extending downward from the upper end of the box cover 4 to limit the detergent box 2 to be in the pulled-out state. By setting two limits on the outer side and the upper side, it is helpful to increase the limit of the detergent box from being pulled out to the detergent adding state, and try to avoid the situation where the detergent box is pulled outward.

[0058] For the assembly of the supporting roller component 3 , the water box body 1 has two left and right body side walls 11 , a notch 13 is provided at the front end of the body side wall 11 , and the supporting roller component 3 is fixed in the notch 13 .

[0059] See also Fig.14 and Fig.15 As shown, the water box in the embodiment is arranged on the pulsator washing machine, a clothing inlet 201 is provided on the control panel seat 20, a receiving cavity for receiving the water box body 1 is provided on the rear side of the clothing inlet 201, a box cover 4 is fixed on the water box body 1, the water box body 1 is fixed in the receiving cavity, and the detergent box 2 can be pulled out and installed in the water box body 1.

[0060] In other embodiments, the water box may also be used in a drum washing machine.

[0061] The above is only a preferred embodiment of the present invention, and does not limit the present invention in other forms. Any technician familiar with the profession may use the above disclosed technical content to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention without departing from the technical solution of the present invention still belongs to the protection scope of the technical solution of the present invention.
