Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a distributor. Background Technology

[0002] In related technologies, the dispenser includes a housing and a cover. The housing has a receiving groove and a guide rail. The cover can move along the guide rail to open or close the receiving groove.

[0003] After the cover is in place, it needs to be pressed down again to make the cover and the fastening mechanism lock together to achieve a sealed fit between the cover and the opening of the receiving groove. This is a cumbersome process. Utility Model Content

[0004] To solve at least one of the above-mentioned technical problems, the following technical solution is provided:

[0005] A dispenser includes: a housing and a cover, the housing having a first wall portion facing the cover in a vertical direction, the first wall portion having a receiving groove, the cover being movable relative to the housing in a front-rear direction, the cover having a first position in which the cover covers the opening of the receiving groove;

[0006] The opening of the receiving groove has a mating part. The housing has a first side and a second side arranged opposite to each other in the front-rear direction. The cover can move from the first side toward the second side in the front-rear direction to a first position. In the front-rear direction, from the first side toward the second side, the mating part has a first sub-part and a second sub-part. The second sub-part is farther away from the first side than the first sub-part. The height of the second sub-part is greater than or equal to the height of the first sub-part, and the height of the mating part gradually increases. In the first position, the cover and at least part of the gradually increasing height of the mating part abut against each other to achieve a sealing fit.

[0007] Since the cover can move relative to the shell in the front-back direction, and in the front-back direction from the first side to the second side, the second sub-part is farther away from the first side than the first sub-part, the height of the second sub-part is greater than or equal to the height of the first sub-part, and the height of at least part of the mating part gradually increases, when the cover moves from the first side to the second side to the first position, at least part of the cover and the mating part can be made to abut, thereby achieving a sealed fit, eliminating the need to press the cover down, thus simplifying the operation.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] like Figure 1-13As shown, a dispenser includes a housing 100 and a cover 200. The housing 100 has a first wall 3 facing the cover in the vertical direction (perpendicular to the front-back direction). The first wall 3 has a receiving groove 1 for storing materials, such as dishwashing powder. The cover 200 has a second position and a first position. In the second position, the cover 200 opens the opening of the receiving groove 1, and a gap is left between the cover 200 and the first wall 3 in the vertical direction. In the first position, the cover 200 covers the opening of the receiving groove 1. The opening of the receiving groove 1 has a mating part 2. The housing has a first side 101 and a second side 102 arranged opposite each other in the front-back direction. In the front-back direction, the first position is located between the first side 101 and the second side 102. The cover can move (specifically slide) from the first side 101 toward the second side 102 in the front-back direction to the first position. In the first position, the cover 200 can abut against at least a portion of the mating part 2 to achieve a sealing fit. Side 101 faces the second side 102. The mating part has a first sub-part 22 and a second sub-part 23. The second sub-part 23 is farther away from the first side 101 than the first sub-part 22. The height of the second sub-part 23 is greater than or equal to the height of the first sub-part 22 (the housing 100 has a first bottom surface 4, which is perpendicular to the vertical direction. The first bottom surface 4 and the first wall part 3 described later are located on opposite sides of the housing 100. Here, the height of the first sub-part 22 means the distance between the first sub-part 22 and the side facing away from the housing 100 and the first bottom surface 4 in the vertical direction. The height of the second sub-part 23 means the distance between the second sub-part 23 and the side facing away from the housing 100 and the first bottom surface 4 in the vertical direction). It should be noted that: the first sub-part 22 and the second sub-part 23 can be any two parts of the mating part. As long as the second sub-part 23 is farther away from the first side 101 than the first sub-part 22 in the front-back direction, then the height of the second sub-part 23 is greater than or equal to the height of the first sub-part 22. The height of the mating part 2 (here, height means the distance between the side of the mating part 2 facing away from the housing 100 and the first bottom surface 4 in the vertical direction) gradually increases at least partially (that is, in the front-back direction, from the first side 101 to the second side 102, the height of the mating part 2 is raised overall). The part of the mating part 2 whose height gradually increases is defined as the first part. In the first position, the cover 200 abuts against at least the part of the mating part 2 whose height gradually increases (that is, the cover abuts against at least the part of the first part) to achieve a sealing fit.

[0029] In this way, since the cover can move relative to the shell in the front-back direction, and in the front-back direction from the first side 101 toward the second side 102, the second sub-part 23 is farther away from the first side 101 than the first sub-part 22, the height of the second sub-part 23 is greater than or equal to the height of the first sub-part 22, and the height of at least a portion of the mating part gradually increases, when the cover moves from the first side 101 toward the second side 102 to the first position, at least a portion of the cover and the mating part can abut against each other, thereby achieving a sealed fit. In contrast, in the prior art solution, the height of the wall corresponding to the opening of the receiving groove is maintained... If the cover is simply moved horizontally to the position where the opening of the receiving groove is closed, although the closing action is simplified, it will aggravate the wear of the sealing components used for sealing and increase the resistance to the movement of the cover. Therefore, a height difference is set between the moving track of the cover and the position where the opening of the receiving groove is closed. After the cover is moved horizontally into place, it continues to move downward to seal with the wall corresponding to the opening of the receiving groove, thereby reducing the wear of the sealing components used for sealing, but increasing the closing action. In contrast, this application reduces the wear of the cover (specifically the sealing component mentioned later) and also omits the operation of pressing the cover down, thereby simplifying the action.

[0030] In this embodiment, along the front-back direction from the first side 101 to the second side 102, the height of the mating part 2 increases continuously; in some embodiments, the height of the mating part 2 may also increase discontinuously, such as having one or more segments in the middle (multiple segments mean at least two segments), and the height of the mating part 2 remains constant; in other embodiments, along the front-back direction, the height of the mating part 2 first remains constant and then gradually increases; in still other embodiments, along the front-back direction, the height of the mating part 2 first gradually increases and then remains constant.

[0031] The mating part 2 protrudes from the first wall part 3; the cover 200 has a sealing part 201. In the first position, along the vertical direction, the projection of the mating part 2 onto the cover 200 is at least partially located on the sealing part 201 (in this embodiment, the projection of the mating part 2 onto the cover 200 is entirely located on the sealing part 201; in some embodiments, the projection of the mating part 2 onto the cover 200 is only partially located on the sealing part 201). The sealing part 201 can be used to seal with the mating part 2. Specifically, in the first position, the sealing part 201 abuts against the mating part 2 to achieve a sealing fit between the two. In this embodiment, the mating part is arranged around the periphery of the opening of the receiving groove, that is, the mating part is arranged to form a complete circumference around the opening of the receiving groove; in some embodiments, the mating part is located at a partial position around the opening of the receiving groove, that is, the mating part does not need to be arranged to form a complete circumference.

[0032] In this way, since the mating part 2 protrudes from the first wall part 3, it is beneficial for the sealing part 201 of the cover 200 to abut and fit with the mating part 2 in the vertical direction.

[0033] Along the vertical direction, and from the bottom wall corresponding to the receiving groove 1 toward the opening of the receiving groove 1, the wall thickness of the mating part 2 gradually decreases. Thus, because the wall thickness of the mating part 2 gradually decreases, that is, the area of ​​the side of the mating part 2 facing the sealing part 201 is small (i.e., the contact surface between the mating part 2 and the sealing part 201), less force is required to ensure a tight fit between the mating part 2 and the sealing part 201, thereby reducing the burden on the related power mechanism for related actions.

[0034] In the front-rear direction, the receiving groove 1 has a third side 11 and a fourth side 12, with the fourth side 12 being farther away from the first side 101 than the third side 11. On the third side 11, the mating part 2 has a notch 21, and the first wall part 3 is connected to the bottom wall of the notch 21. In this embodiment, in the first position, a gap is left between the cover and the bottom wall of the notch 21 in the vertical direction. In this embodiment, in the vertical direction, the main body of the mating part is higher than the bottom wall of the notch, and in the first position, the cover 200 (specifically the sealing part 201) abuts against the main body of the mating part 2 to achieve a sealed fit, but a gap is left between the cover 200 and the bottom wall of the notch 21. In some embodiments, the cover 200 abuts against the main body of the mating part to achieve a sealed fit, and also abuts against the bottom wall of the notch to achieve a sealed fit.

[0035] The dispenser is installed in the dishwasher. During normal operation of the dishwasher, the front-to-back direction of the dispenser is parallel or approximately parallel to the direction of gravity. Thus, since the mating part 2 has a notch 21 on the third side 11 and the bottom surface of the notch 21 is connected to the first wall part 3, in the corresponding working condition, water can flow from the first wall part 3 through the notch 21 and into the receiving tank 1, thereby carrying out the material, such as dishwashing powder, located in the receiving tank 1.

[0036] The housing 100 has a first guide rail portion 5 and a second guide rail portion 6, which are disposed opposite to each other. The cover 200 has a first limiting flange 204 and a second limiting flange 205 on both sides. The first limiting flange 204 is at least partially located in the first guide rail portion 5, meaning it can be partially or entirely located in the first guide rail portion 5. The second limiting flange 205 is at least partially located in the second guide rail portion 6, meaning it can be partially or entirely located in the second guide rail portion 6. 6; and the first limiting flange 204 can slide along the first guide rail portion 5, and the second limiting flange 205 can slide along the second guide rail portion 6, thereby enabling the cover 200 to move along the first guide rail portion 5 and the second guide rail portion 6 in the front-back direction; the extension directions of the first guide rail portion 5 and the second guide rail portion 6 are both parallel to the front-back direction, in other words, the extension paths of the first guide rail portion 5 and the second guide rail portion 6 are straight segments. It should be noted that errors caused by manufacturing and processing, which make the extension directions of the first guide rail portion 5 and the second guide rail portion 6 approximately parallel to the front-back direction, are also within the scope of protection of this application.

[0037] In this way, since the extension paths of the first guide rail 5 and the second guide rail 6 are straight segments, it is easier to improve the speed of sliding the cover 200 along the first guide rail 5 and the second guide rail 6.

[0038] The cover 200 has a limiting groove 202, which is located on the side of the cover 200 facing the housing 100 in the vertical direction, and the opening of the limiting groove 202 faces the body of the housing 100; the cover 200 includes a sealing member 203, at least a portion of which is located in the limiting groove 202. In this embodiment, a portion of the sealing member 203 is located in the limiting groove 202. In some embodiments, the sealing member 203 may be entirely located in the limiting groove 202; the sealing part 201 is located on the side of the sealing member 203 facing the housing 100, and the sealing part 201 is exposed in the limiting groove 202.

[0039] In this way, since the sealing part 201 is located on the side of the sealing member 203 facing the housing 100, and the sealing member 203 is located in the limiting groove 202, the limiting groove 202 plays a limiting role on the sealing member 203 to ensure the reliability of the position of the sealing member 203, that is, to reduce the offset of the sealing part 201 during use.

[0040] The sealing part 201 has a mating surface 2011 and a transition surface 2012. The mating surface 2011 is used to seal with the mating part 2. The mating surface 2011 is connected to the transition surface 2012. In the front-back direction, the transition surface 2012 is closer to the second side 102 than the mating surface 2011. The transition surface 2012 is a curved surface or an inclined surface that is inclined relative to the mating surface 2011.

[0041] Thus, since the transition surface 2012 is closer to the second side 102 than the mating surface 2011 in the front-back direction, and the transition surface 2012 is a curved surface or an inclined surface that is inclined relative to the mating surface 2011, when the cover 200 moves from the first side 101 to the first position, the transition surface 2012 plays a guiding and transitioning role, reducing the wear of the sealing part 201 and the mating part 2 in the front-back direction, and facilitating the mating surface 2011 and the mating part 2 to fit and seal.

[0042] The dispenser also includes an elastic element 7 and a first limiting element 8. The elastic element 7 is connected to the housing 100, and the other end of the elastic element 7 is connected to the cover 200. In the first position, the elastic element 7 is in a compressed state, so that the cover 200 tends to move from the first position toward the first side 101. The first limiting element 8 is connected to the housing 100, and the cover 200 has a second limiting element 206. The second limiting element 206 is connected to the body of the cover 200. In the first position along the front-rear direction, at least a portion of the first limiting element is closer to the first side 101 than the second limiting element and abuts against the second limiting element to prevent the cover 200 from moving from the first position toward the first side 101.

[0043] When the cover 200 is in the first position, the elastic member 7 is in a compressed state, so that the first limiting member 8 and the second limiting member 206 abut against each other in the front-back direction. After the first limiting member 8 and the second limiting member 206 contact and abut against each other, under the action of the elastic member 7, the cover 200 moves from the first position to the first side 101 in the front-back direction.

[0044] like Figure 14 As shown, in this embodiment,

[0045] The first wall portion 3 has a first region 31 and a second region 32. In the front-back direction, the second region 32 is farther away from the first side 101 than the first region 31. The receiving groove 1 is located in the second region. In the front-back direction, it extends from the first side 101 toward the second side 102. The height of the second region 32 gradually increases relative to the first region. The mating part 2 constitutes part of the second region 32. In the first position, in the vertical direction, the projection of the sealing part 201 on the first wall portion 3 is located on the mating part 2.

[0046] In this way, since the mating part 2 constitutes part of the second region 32, that is, the sealing part 201 is sealed and fitted with the second region 32, in other words, the area of ​​the sealing surface is increased, thereby improving the reliability of the seal.

[0047] The technical features of the above-described solutions can be combined. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should all be considered to be within the scope of this application.
