Abstract
Description
Technical Field
[0001] The present application relates to the technical field of household appliances, and particularly relates to a clothing treatment agent box assembly and a washing machine. Background Art
[0002] For the lid of the detergent addition port on the dispenser of existing washing machines for automatic detergent dispensing, there are two forms. One is a flip cover type, which is connected to a flip cover plastic part through a rotating shaft, and there is a silicone seal on the plastic part. Opening the flip cover opens the liquid addition port, and closing it seals the liquid addition port. In this way, the lid is connected to the dispenser, and the lid will not be removed during the liquid addition process, so there is no possibility of loss. However, there are the following problems. For some products, the flip cover just closes without a fixing structure, resulting in almost no compression of the sealing silicone part and unable to play a sealing role. When the washing machine is tilted, the detergent is likely to leak out. For some products, the flip cover is engaged with the dispenser through a hook on the lid to provide pressure to the sealing silicone part to produce a sealing effect. But in this way, on the one hand, when the clamping force is large, it is not easy for the user to open the flip cover when adding detergent. On the other hand, the hook is an elastic structure, and the pressure it can provide is limited, and the flip cover will still open and leak liquid when the washing machine is tilted. The other form of the lid is a screw cap type, similar to the common screw connection. The liquid addition lid is circular with a hook on it. The connection method with the dispenser is not through the deformation of the hook, but by first inserting the hook on the lid into the corresponding notch on the dispenser, and then rotating the lid so that the hook slides into the corresponding protruding clamping position on the dispenser, so that the hook tightens the liquid addition lid and squeezes the sealing silicone on the lid to achieve sealing and fixing. This fixing method has a relatively reliable seal and will not leak liquid when tilted. However, when the user adds detergent and removes the lid, they often place it casually, resulting in a relatively high loss rate. And generally, there is detergent sticking to the lid, which is easy to get on the hands and the placement location during the placement process. Summary of the Utility Model

Detailed implementation manners
[0032] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present application, the following will further describe the solutions of the present application. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
[0033] Many specific details are set forth in the following description in order to fully understand the present application, but the present application can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present application, rather than all of the embodiments.
[0034] The following refers to Figures 1 to 4Describe a laundry treatment agent cartridge assembly according to an embodiment of the first aspect of the present application.
[0035] As Figure 1 shown, the laundry treatment agent cartridge assembly according to an embodiment of the first aspect of the present application includes a cartridge body 1, a flip cover 2, and a locking mechanism 3.
[0036] Specifically, as Figures 2 to 4 shown, a receiving cavity 102 is formed inside the cartridge body 1, and a liquid adding port 101 communicating with the receiving cavity 102 is formed on the cartridge body 1; the receiving cavity 102 inside the cartridge body 1 may include a detergent cavity and / or a fabric softener cavity, and the liquid adding port 101 on the cartridge body 1 may include a detergent liquid adding port and / or a fabric softener liquid adding port. The detergent liquid adding port may communicate with the detergent cavity for adding detergent for washing clothes into the detergent cavity, and the fabric softener liquid adding port may communicate with the fabric softener cavity for adding fabric softener for washing clothes into the fabric softener cavity.
[0037] In the cartridge body 1 of the embodiment of the present application, a receiving cavity 102 with other functional uses may also be provided, and each receiving cavity 102 corresponds to a liquid adding port 101 for injecting a corresponding solution.
[0038] The flip cover 2 is rotatably provided at the liquid adding port 101, and the flip cover 2 may be hermetically connected to the peripheral edge of the liquid adding port 101. When the flip cover 2 is opened, a solution can be added into the corresponding receiving cavity from the liquid adding port 101.
[0039] An installation opening 202 is provided on the flip cover 2, and the installation opening 202 communicates with the receiving cavity; the locking mechanism 3 is rotatably provided at the installation opening 202, and the locking mechanism 3 is hermetically connected to the peripheral edge of the installation opening 202.
[0040] Specifically, the locking mechanism 3 is provided at the installation opening 202, and the locking mechanism 3 is movable between a first position and a second position; when the locking mechanism 3 is in the first position, the locking mechanism 3 is locked with the cartridge body 1 and the locking mechanism 3 axially presses the flip cover 2 to make the flip cover 2 hermetically connected to the peripheral edge of the liquid adding port 101. When the locking mechanism 3 is in the first position, the flip cover 2 is in a locked state, that is, even if the washing machine is overturned, the solution in the receiving cavity 102 will not leak from the liquid adding port 101; when the locking mechanism 3 is in the second position, the locking mechanism 3 unlocks the flip cover 2 from the cartridge body 1, and the flip cover 2 can be turned outwards to open the liquid adding port 101. Opening the liquid adding port 101 by flipping avoids the loss of the lid.
[0041] Furthermore, as Figure 2As shown, in some embodiments of the present application, the locking mechanism 3 includes a knob 301, a connecting rod 302, and a locking cover 303 connected in sequence. The knob 301 is located on the side of the installation opening 202 away from the accommodation cavity. The connecting rod 302 is rotatably disposed in the installation opening. The locking cover 303 is located inside the flip cover 2, and a locking protrusion 303a extends radially outward along the peripheral edge of the locking cover 303. The outer end of the connecting rod 302 is connected to the knob 301, and the inner end of the connecting rod 302 is connected to the locking cover 303. The locking cover 303 is located inside the flip cover 2 and is arranged parallel to the flip cover 2. The locking cover 303 is in the shape of a disc, and a locking protrusion 303a extends radially outward along the outer circumferential surface of the locking cover 303. A stop block 103 for cooperating with the locking protrusion 303a is formed by protruding along the thickness direction on the inner side surface of the box body 1 around the liquid filling port 101.
[0042] When the locking mechanism 3 is in the first position, the locking protrusion 303a and the stop block 103 are axially abutted against each other. When the locking mechanism 3 is in the second position, the locking protrusion 303a and the stop block 103 are misaligned. Specifically, the locking protrusion 303a is located inside the outlet end of the liquid filling port 101 and has a clearance fit with the liquid filling port 101.
[0043] Exemplarily, the knob 301 is at the outer end of the connecting rod 302, which is convenient for the user to operate the locking mechanism 3 when the flip cover 2 is closed at the liquid filling port 101. The knob 301, the connecting rod 302, and the locking cover 303 move synchronously. When the knob 301 is rotated, the locking cover 303 rotates synchronously inside the flip cover 2. When the locking mechanism 3 rotates to the first position, the locking protrusion 303a rotates with the locking mechanism 3 to a position corresponding to the stop block 103 and also abuts against the end face of the stop block 103 away from the flip cover 2. An axially mutually pressing force is formed between the locking protrusion 303a and the stop block 103. Since the box body 1 is fixed, during the process of the locking mechanism 3 rotating from the second position to the first position, the locking mechanism 3 moves downward in a straight line, thereby driving the flip cover 2 to press downward and closely adhere to the liquid filling port 101, thereby realizing the sealing between the flip cover 2 and the liquid filling port 101 and avoiding the problem of liquid leakage at the liquid filling port 101 when the washing machine is tilted. When the locking mechanism 3 rotates to the second position, the locking protrusion 303a is disengaged from the stop block 103 and enters the liquid filling port 101 to have a clearance fit with the liquid filling port 101. At this time, the flip cover 2 can be flipped outward to open the liquid filling port 101. The flip - over design of the flip cover 2 ensures that when the liquid filling port 101 is opened, the flip cover 2 is still connected to the box body 1, avoiding the loss of the cover when the liquid filling port 101 is opened.
[0044] Furthermore, in some embodiments of the present application, a first counterbore 201 is formed by inwardly recessing on the outer side surface of the flip cover 2. The first counterbore 201 is correspondingly arranged with the installation opening 202, and the knob 301 is rotatably disposed in the first counterbore 201.
[0045] The outer side surface of the flip cover 2 refers to the side surface that is away from the accommodation cavity 102 when the flip cover 2 is closed at the liquid filling port 101, and the side surface opposite to the outer side surface is the inner side surface of the flip cover 2; a first sunken hole 201 is formed by inward depression of the outer side surface of the flip cover 2, the installation opening 202 extends from the bottom of the first sunken hole 201 to the inner side surface of the flip cover 2, the knob 301 is rotatably arranged in the first sunken hole 201, the outer end of the connecting rod 302 is connected to the inner side surface of the knob 301, and the connecting rod 302 rotatably passes through the installation opening 202, and the inner end of the connecting rod 302 is fixedly connected to the locking cover 303 after passing through the installation opening 202.
[0046] In some embodiments of the present application, both the first sunken hole 201 and the installation opening 202 are circular holes, the knob 301 includes a rotating disk and a handle provided on the outer side surface of the rotating disk, the shape of the rotating disk is disk-shaped, and the diameter of the rotating disk is smaller than the diameter of the first sunken hole 201, the shape of the handle is strip-shaped, the handle is fixed on the outer side surface of the rotating disk, and the rotating disk is in sealing cooperation with the first sunken hole 201 in the circumferential direction.
[0047] The shape of the connecting rod 302 is cylindrical, and the diameter of the connecting rod 302 is smaller than the diameter of the installation opening 202, and the inner end of the connecting rod 302 is detachably connected to the locking cover 303. Specifically, the connecting rod 302 and the locking cover 303 can be fixed together by connection methods such as threaded connection and snap connection. Exemplarily, in some embodiments of the present application, a threaded hole is axially formed in the inner end of the connecting rod 302, and the fastener passes through the locking cover 303 from bottom to top and cooperates with the threaded hole to fix the two together.
[0048] Further, as Figures 4 to 6 shown, in some embodiments of the present application, the number of locking protrusions 303a is multiple, the multiple locking protrusions 303a are arranged at intervals along the circumferential direction of the locking cover 303, and the number of the stop blocks 103 is equal to and corresponds to the number of the locking protrusions 303a one by one. Specifically, the multiple locking protrusions 303a are evenly distributed along the circumferential direction of the locking cover 303, and the stop blocks 103 are evenly distributed around the liquid filling port 101. When the locking mechanism 3 rotates to the first position, the multiple locking protrusions 303a and the multiple stop blocks 103 just abut against each other one by one, avoiding the skew of the locking cover 303 when only one locking protrusion 303a cooperates with the stop block 103. When the locking mechanism 3 rotates to the second position, the multiple locking protrusions 303a are simultaneously separated from the multiple stop blocks 103.
[0049] Further, in some embodiments of the present application, the liquid filling port 101 includes a first mating hole section 101a and a second mating hole section 101b arranged in sequence along the axial direction. The first mating hole section 101a is located on the side of the second mating hole section 101b away from the accommodating cavity 102. The size of the first mating hole section 101a is larger than that of the second mating hole section 101b, and the side wall of the first mating hole section 101a is connected to the side wall of the second mating hole section 101b through a first step surface 101c. The outer circumferential surface of the flip cover 2 includes a first outer wall surface 203, a second outer wall surface 204, and a third outer wall surface 205 arranged in sequence along the thickness direction. The first outer wall surface 203 and the second outer wall surface 204 are connected through a second step surface 206, and the second outer wall surface 204 and the third outer wall surface 205 are connected through a third step surface. Among them, the first outer wall surface 203 and the second outer wall surface 204 are in clearance fit with the side wall of the first mating hole section 101a, and the third outer wall surface 205 is in clearance fit with the side wall of the second mating hole section 101b.
[0050] The laundry treatment agent box assembly further includes a first seal 4. The shape of the first seal 4 is an annular shape adapted to the shape of the second outer wall surface 205. The first seal 4 is sleeved on the second outer wall surface 204, and the axial length of the first seal 4 is at least equal to the axial length of the second outer wall surface 204. When the flip cover 2 is closed at the liquid filling port 101, one end of the first seal 4 abuts against the second step surface, and the other end of the first seal 4 abuts against the first step surface. When the locking mechanism 3 rotates to the first position, the locking protrusion 303a moves downward, applying a downward pressure to the flip cover 2, thereby squeezing the first seal 4 to achieve the sealed fit between the flip cover 2 and the liquid filling port 101.
[0051] Exemplarily, the outer shape of the flip cover 2 is rectangular, both the first mating hole section 101a and the second mating hole section 101b are rectangular holes, and the first outer wall surface 203 of the flip cover 2 is rotatably connected to the first mating hole section 101a through a rotating shaft 6 to realize the flipping movement of the flip cover 2.
[0052] A return spring 7 is provided on the rotating shaft 6. When the locking mechanism 3 rotates to the second position, the locking protrusion 303a disengages from the stopper, and the flip cover 2 is unlocked. Under the action of the return spring 7, the flip cover 2 flips outward and automatically opens the liquid filling port 101.
[0053] Further, in some embodiments of the present application, a second seal 5 is provided between the inner side surface of the knob 301 and the bottom wall of the first counterbore 201. The second seal 5 is an annular sealing ring. The second seal 5 is sleeved on the connecting rod 302, and the outer end of the second seal 5 abuts against the inner side surface of the knob 301, and the inner end of the second seal 5 abuts against the bottom wall of the first counterbore 201. When the locking mechanism 3 rotates to the first position, the knob 301 moves axially inward, and the knob 301 presses the second seal 5, improving the sealing effect between the knob 301 and the mounting opening 202 and avoiding liquid leakage from the mounting opening 202.
[0054] Further, in some embodiments of the present application, an inclined guiding slope 103a is provided on the turning-in side of the stop block 103. Specifically, the turning-in side of the stop block 103 refers to the side surface that the locking lug 303a first contacts when approaching the stop block 103. The side opposite to the turning-in side of the stop block is the turning-out side of the stop block, that is, the side where the locking lug 303a finally contacts the stop block 103 when disengaging from the stop block 103. The guiding slope 103a is inclined from the bottom surface to the top surface of the stop block 103 in a direction approaching the center line of the stop block 103. After the locking lug 303a rotates to the position where it contacts the guiding slope 103a of the stop block 103, it moves along the guiding slope 103a to the position where it abuts against the top surface of the stop block 103. During this process, the locking lug 303a has a linear motion along the axis, thereby pressing the flip cover 2 to achieve a sealing fit between the flip cover 2 and the liquid filling port 101 and avoiding liquid leakage from the liquid filling port 101.
[0055] Further, in some embodiments of the present application, a stop block 103 is provided on any side in the circumferential direction of the first mating hole section 101a, and the number of stop blocks 103 on each side can be one or multiple. Exemplarily, the first mating hole section 101a is a square hole, and one stop block 103 is provided on each side of the first mating hole section 101a, and the stop block 103 is correspondingly arranged at the middle of each side of the first mating hole section 101a.
[0056] The shape of the locking cover 303 is circular, and the diameter of the locking cover 303 is smaller than the side length of the first mating hole section 101a. The distance between the outer end faces of the two relatively arranged locking lugs 303a along the radial direction is smaller than the length of the diagonal of the first mating hole section 101a. When the locking lug 303a rotates to the position corresponding to the stop block 103, the locking cover 303 and the box body 1 are locked to each other, and the flip cover 2 and the liquid filling port 101 are in sealing fit to avoid liquid leakage. When the locking lug 303a rotates to the diagonal position of the first mating hole section 101a, the locking lug 303a enters the first mating hole section 101a and there is a gap between the locking lug 303a and the side wall of the first mating hole section 101a, and the flip cover 2 and the box body 1 are unlocked from each other, and the flip cover 2 can be turned outwards to open the liquid filling port 101.
[0057] Similarly, in some other embodiments, the liquid filling port 101 may also be of other shapes, and the shape of the flip cover 2 is adapted to the shape of the liquid filling port 101. The size of the liquid filling port 101 at the position corresponding to the first position is larger than the size of the liquid filling port 101 at the position corresponding to the second position. Exemplarily, the shape of the liquid filling port 101 may be oval, triangular or other polygons.
[0058] In some embodiments of the present application, a washing machine is further provided, which includes the laundry treatment agent box assembly in any of the above embodiments.
[0059] The other components and operations of the washing machine according to the embodiments of the present application are known to those of ordinary skill in the art and will not be described in detail herein.
[0060] In summary, for the laundry treatment agent box assembly provided by the embodiments of the present application, the flip cover 2 is used in cooperation with the liquid filling port 101. When the liquid filling port 101 is opened, the flip cover 2 is not easily lost and does not need to be placed somewhere and contaminated during the liquid filling process. When unlocking and locking the flip cover 2, the rotation locking mechanism 3 is used to complete. By rotating the locking mechanism 3 to different positions, the unlocking and locking of the flip cover 2 are realized. At the same time, during the locking process of the flip cover 2, the first sealing member 4 and the second sealing member 5 are squeezed to achieve a good sealing effect and avoid liquid leakage from the liquid filling port 101. It combines the advantages of the flip type and the knob type and abandons the disadvantages of the single flip type and the single knob type.
