DETAILED DESCRIPTION OF THE INVENTION

[0010] The following describes the embodiments of the present application in conjunction with the drawings, and the described embodiments are not all of the embodiments but only some of the embodiments of the present application. All other embodiments that can be obtained by a person skilled in the art based on the embodiments of the present application without performing creative work fall within the scope of protection of the present application.

[0011] In the description of this application, unless otherwise clearly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense, and may refer to, for example, a fixed connection, a detachable connection, or integration, a mechanical connection, an electrical connection, a direct connection, an indirect connection via an intermediate medium, internal communication between two elements, or an interaction between two elements. Those skilled in the art can understand the meaning of the above terms in this application according to the specific circumstances.

[0012] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include direct contact between the first and second features, or may include contact between the first and second features without direct contact but via another feature between them. Furthermore, a first feature being "above," "above," and "on the upper surface" of a second feature may include the first feature being directly above and diagonally above the second feature, or may simply indicate that the horizontal height of the first feature is higher than that of the second feature. A first feature being "below," "below," and "on the lower surface" of a second feature may include the first feature being directly below and diagonally below the second feature, or may simply indicate that the horizontal height of the first feature is lower than that of the second feature.

[0013] In the related art, the washing speed of the detergent case cannot meet the requirement of quickly washing away detergent at low water pressure, and there is also the problem that detergent adhering to the side walls of the detergent case cannot be washed off, resulting in low detergent utilization. In contrast, this embodiment provides a detergent case and a laundry treatment device to solve the above technical problems.

[0014] Example 1 As shown in Figures 1 and 2, in this embodiment, the detergent case includes a first storage chamber 111, which has at least one water inlet 21 at its top. A water inlet module 3 is provided at the water inlet 21. The water inlet module 3 can increase the pressure of the water flowing through the water inlet 21 and direct the water against the side wall of the first storage chamber 111. Detergent can be placed in the first storage chamber 111, and the water flows into the first storage chamber 111 through the water inlet 21 at the top of the first storage chamber 111. The water inlet module 3 increases the pressure of the water flowing through the water inlet 21, ensuring that the water flows into the first storage chamber 111 at a low water pressure, thereby quickly rinsing away the detergent. At the same time, the water inlet module 3 directs the water against the side wall of the first storage chamber 111 so that the water can wash away any detergent adhering to the side wall of the first storage chamber 111, thereby improving the utilization rate of the detergent.

[0015] 2 and 3, the water inlet module 3 comprises a water inlet pipe 31, which is disposed within the first storage chamber 111, a first end of which is connected to the water inlet port 21, and a second end of which is connected to a pressure intensifier plate 32, which is configured to receive the water flow within the water inlet pipe 31, and which is inclined toward the bottom of the first storage chamber 111 and extends to the side wall of the first storage chamber 111, forming a first long flow path between the pressure intensifier plate 32 and the side wall of the first storage chamber 111. The water flow entering the water inlet pipe 31 hits the pressure intensifier plate 32, which is inclined downward and spaced apart from the side wall of the first storage chamber 111 to form a first long flow path that can increase the inlet water pressure. The pressure intensifier plate 32 also serves to disperse the water flow so that it can cover the entire side wall and flow down, thereby increasing the area over which the water hits the side wall of the first storage chamber 111 and ensuring that detergent does not remain on the side wall of the first storage chamber 111.

[0016] In this embodiment, the intensifier plate 32 is L-shaped, with its vertical plate connected to the water inlet pipe 31, and the vertical plate is provided with an arc-shaped notch 33 extending downward toward the horizontal plate of the intensifier plate 32, and the upper surface of the horizontal plate of the intensifier plate 32 is provided with a downwardly sloping slope 34, so that the water flow entering the water inlet pipe 31 hits the arc-shaped surface of the arc-shaped notch 33 to form a dispersed fan-shaped spray, thereby increasing the area over which the water hits the side wall of the first containing chamber 111. In this embodiment, the intensifier plate 32 can be integrally connected to the water inlet pipe 31, which has high structural strength and is easy to process.

[0017] The inner wall of the arc-shaped notch 33 is arc-shaped, and the opening of the arc-shaped notch 33 is arranged toward the side wall of the first storage chamber 111, thereby forming a fan-shaped water flow toward the side wall of the first storage chamber 111 and increasing the area that washes the side wall of the first storage chamber 111.

[0018] The water inlet module 3 further includes a water-shielding material 35, which is connected to the pressure booster plate 32, and is configured to block the flow of water away from the side wall of the first storage chamber 111, thereby preventing the water flow from being dispersed and affecting the effect of washing away detergent adhering to the side wall of the first storage chamber 111.

[0019] To facilitate installation of the water shielding material 35 and simplify the structure of the water inlet module 3, the water shielding material 35 is an L-shaped plate and is installed on the side of the intensifier plate 32 that faces away from the side wall of the first storage chamber 111, so as to block the water flow without affecting the outflow of water. The vertical plate of the water shielding material 35 is connected to a first end of the intensifier plate 32, and the horizontal plate of the water shielding material 35 is connected to a second end of the intensifier plate 32. For example, the vertical plate of the water shielding material 35 is connected to the vertical plate of the intensifier plate 32, and the vertical plate can extend to the end connected to the water inlet 21 of the water inlet pipe 31 to increase the water shielding area. The horizontal plate of the water shielding material 35 is connected to the underside of the horizontal plate of the intensifier plate 32, providing a certain support for the horizontal plate of the intensifier plate 32.

[0020] The water shielding material 35 may be formed integrally with the pressure intensifier plate 32 and the water inlet pipe 31, thereby increasing the structural strength of the water inlet module 3.

[0021] In this embodiment, as shown in Figures 1, 4, 5 and 6, the detergent case further includes a case body 1 and a main body part 2, the main body part 2 is connected to the case body 1, the main body part 2 and the case body 1 form a first storage chamber 111, and the water inlet 21 is provided in the main body part 2.

[0022] 4, the case body 1 is formed with a first chamber 11 and a second chamber 12 recessed inward, and the first chamber 11 and the second chamber 12 are arranged side by side along the length of the case body 1. For example, a partition part is provided inside the case body 1 to divide the case body 1 into the first chamber 11 and the second chamber 12. A drain chamber 13 is provided laterally in the width direction of the case body 1, perpendicular to the first chamber 11 and the second chamber 12 and communicating with the first chamber 11 and the second chamber 12, and the drain chamber 13 communicates with an external drain pipe to discharge the water flow to the outside.

[0023] In order to increase the strength of the case body 1, the outer side wall of the case body 1 is further provided with multiple groups of reinforcing rib plates, which are arranged along the circumferential direction of the case body 1.

[0024] 5, the main body part 2 includes a main body support plate formed so that the second accommodating chamber 22 and the third accommodating chamber 23 are recessed downward, and the second accommodating chamber 22 and the third accommodating chamber 23 are arranged side by side along the width direction of the main body part 2. An input port 24 is provided in the main body support plate, and the input port 24 is arranged side by side with the second accommodating chamber 22 and the third accommodating chamber 23. The input port 24 may be, for example, a rectangular input port 24.

[0025] A support member 25 is provided on one side of the inlet 24. The support member 25 extends downward from the main body support plate. The support member 25 is a support plate, and its width is close to that of the inlet 24.

[0026] 4, 5 and 6, after the case body 1 and the main part 2 are installed, the second accommodating chamber 22 and the third accommodating chamber 23 are located in the first chamber 11. The second accommodating chamber 22 and the third accommodating chamber 23 are spaced apart from the first chamber 11, and a guide chamber is formed between the second accommodating chamber 22, the third accommodating chamber 23 and the first chamber 11, and the guide chamber communicates with the drain chamber 13.

[0027] The second storage chamber 22 and the third storage chamber 23 are both provided with siphon caps 4 so that the diluted liquid detergent that has entered the second storage chamber 22 and the third storage chamber 23 can enter the flow chamber and then the drain chamber 13, making them suitable for storing liquid detergent.

[0028] In some embodiments, the second storage chamber 22 can contain bleach, and the third storage chamber 23 can contain fabric softener. During use, the water flows into the second storage chamber 22 and the third storage chamber 23, diluting the bleach in the second storage chamber 22 and the fabric softener in the third storage chamber 23, and then the water is sucked into the directing chamber by the siphon cap 4 located in each storage chamber, passes through the directing chamber, and then flows into the drain chamber 13 connected to the directing chamber, and finally discharged into the drum of the laundry treatment device to perform the washing operation.

[0029] The inlet 24 in the main body support plate is provided corresponding to the second chamber 12, and after the main body part 2 is attached to the case body 1, the main body part 2 and the second chamber 12 are arranged in a surrounding manner to form a first storage chamber 111 having the inlet 24 as an opening, and the first storage chamber 111 is connected to the drainage chamber 13.

[0030] The first storage chamber 111 is large in size and is arranged in parallel with the second storage chamber 22 and the third storage chamber 23. It can be used to store powder detergent or liquid detergent. Powder detergent is poured into the first storage chamber 111 through the inlet 24, and the powder detergent is diluted by the water flow entering the first storage chamber 111 and then directly discharged into the drain chamber 13, then into the drain pipe, and reaches the inside of the laundry treatment device.

[0031] In this embodiment, a gap is provided between the downwardly extending support part 25 on the main body support plate and the bottom wall of the first storage chamber 111, and multiple baffle parts 112 are provided in the gap, and a guide passage is formed between the multiple baffle parts 112 to guide the water flow in the first storage chamber 111 into the drainage chamber 13.

[0032] The baffle components 112 are baffle plates or baffle blocks, and the guide passages between adjacent baffle components 112 prevent the water flow from the first storage chamber 111 from flowing into the drain chamber 13 too quickly, thereby preventing the detergent in the first storage chamber 111 from being quickly washed into the inside of the clothing treatment device before it has completely dissolved. At the same time, the baffle components 112 can also block to some extent foreign matter present in the detergent poured into the first storage chamber 111, preventing the foreign matter from entering the clothing treatment device.

[0033] In this embodiment, the main body part 2 is covered by the case body 1. For example, a locking module that fits between the main body part 2 and the case body 1 is provided, and during installation, the case body 1 can be provided with locking blocks 14 and the main body part 2 with locking grooves 26, so that the two are connected by fitting the locking blocks 14 into the locking grooves 26. During installation, the locking grooves 26 and the locking blocks 14 can be provided in multiple groups and arranged along the circumferential direction of the main body part 2 and the case body 1.

[0034] In order to connect the case body 1 and main part 2 to the clothing treatment device, a first connection boss is provided on the case body 1 and a second connection boss is provided on the main part 2, and the first connection boss and the second connection boss are butted together. When connected, the locking male screw passes through the first connection boss and the second connection boss, locking and fixing the main part 2 and case body 1 to the clothing treatment device.

[0035] In order to ensure the sealing performance when the case body 1 and the main part 2 are engaged and connected together and to prevent water from leaking out, the top surface of the case body 1 and the bottom surface of the main part 2 are provided with matable protruding rib modules 15, which are arranged around the case body 1 and the main part 2 to form sealing grooves arranged along the circumferential direction of the case body 1 and the main part 2, and sealing strips are assembled into the sealing grooves to ensure the sealing performance between the two.

[0036] As shown in Figures 6, 7, 8 and 9, the detergent case of this embodiment further includes a case lid module that is assembled to the main part 1, and between the main part 1 and the case lid module, a water-conducting flow path is formed that is arranged around the first storage chamber 111, the second storage chamber 22 and the third storage chamber 23 and that can introduce water flow into the first storage chamber 111, the second storage chamber 22 and the third storage chamber 23, and the water-conducting flow path is provided with a water inlet water-conducting section that introduces water in the water-conducting flow path into the first storage chamber 111, the second storage chamber 22 and the third storage chamber 23.

[0037] In this embodiment, the detergent case is installed by fitting and fixing the main part 2 and the case body 1 together, so that a plurality of first storage chambers 111, second storage chambers 22 and third storage chambers 23 for storing detergent can be formed between the two, and corresponding guide chambers and drain chambers 13 are provided to allow diluted detergent to be introduced into the laundry treatment device. This allows for the installation of multiple detergent storage chambers, realizes large-capacity and diversified installation, and can meet the usage needs of users who want to add different types of detergent.

[0038] When the detergent case of this embodiment is installed, water-conducting channels are provided between the main part 2 and the case body 1, surrounding the first storage chamber 111, the second storage chamber 22, and the third storage chamber 23. The water-conducting channels are provided with water inlet channels, which allow water to flow directly into the corresponding storage chambers, preventing water leakage. Since the water-conducting channels surround the corresponding storage chambers, the water inlet channels allow water to flow from the water-conducting channels along the peripheries of the first storage chamber 111, the second storage chamber 22, and the third storage chamber 23 and into them. The method of water entering from the periphery of the storage chambers allows water to flow in multiple directions to wash away detergent, resulting in a more thorough washing away of the detergent and a better dilution of the detergent inside.

[0039] When installed, the arrangement of the water inlet conveying section along the periphery of the first storage chamber 111, the second storage chamber 22 and the third storage chamber 23 includes the arrangement of the water inlet conveying section along one side of the first storage chamber 111, the second storage chamber 22 and the third storage chamber 23, or the arrangement of the water inlet conveying section along two opposing sides of the first storage chamber 111, the second storage chamber 22 and the third storage chamber 23, or the arrangement of the water inlet conveying section along the circumferential direction of the first storage chamber 111, along the circumferential direction of the second storage chamber 22 and also along the circumferential direction of the third storage chamber 23. All of the above arrangements fall under the peripheral arrangement defined in this embodiment.

[0040] In this embodiment, the case lid module includes a first case lid part 51 and a second case lid part 52, and the case lid module is used to be assembled and fixed to a table 100. The first case lid part 51 is provided below the table 100, and the second case lid part 52 is provided above the table 100.

[0041] An opening area is opened in the base surface 100, and a folded connecting edge is formed around the opening area, the first case lid part 51 is provided below the folded connecting edge, the second case lid part 52 is provided above the folded connecting edge, and the second case lid part 52 is provided with a female threaded post, and a male screw passes through a screw hole in the first case lid part 51 at the bottom and a screw hole in the folded connecting edge, and then is turned into and fixed in the female threaded post of the second case lid part 52, thereby realizing a connection and fixation between the three.

[0042] As shown in FIG. 10, a sealing part is provided between the first case lid part 51 and the base surface 100, and the sealing part is attached in an annular fitting formed in the first case lid part 51.

[0043] The seal component includes a seal body 61, which is inserted into the annular fitting. Abutment support legs 62 extend outward from the seal body 61 and abut against the side walls of the annular fitting. The abutment support legs 62 are abutment support legs that are provided on the seal body 61 so as to slope upward, thereby achieving a strong seal between the seal component and the first case lid component 51. A strain section 63 is provided at the top of the seal body 61, protruding from the annular fitting and forming a hollow strain chamber therein. The strain section 63 is capable of straining under pressure to seal between the base surface 100 and the first case lid component 51.

[0044] The annular fitting portion is an annular fitting groove and is arranged along the circumferential direction of the first case lid part 51. The annular fitting groove has an annular opening facing the base surface 100, and the annular fitting groove has an annular bottom wall and annular side walls provided on both sides of the annular bottom wall, and the annular opening faces the annular bottom wall. A sealing part is provided between the first case lid part 51 and the base surface 100, and the sealing part is also provided in an annular shape to achieve fitting with the annular fitting portion.

[0045] The first case lid part 51 may be either rectangular or circular, and is made of a plastic material, and the annular fitting part is molded directly and integrally with the first case lid part 51 during molding.

[0046] To meet the needs of sealing and mounting, the sealing parts are made of rubber material and are directly molded into the product during molding.

[0047] In this embodiment, the seal body 61 includes a press-fit portion and a vertical portion. The press-fit portion is located on the top surface of the vertical portion, which is a vertical rod. The maximum width of the vertical portion is smaller than the distance between the two annular side walls of the annular mounting groove, so that the seal body 61 can be quickly installed in the annular mounting groove. The press-fit portion is a press-fit rod, and its maximum width is greater than the maximum width of the vertical portion and greater than the width of the two annular side walls. During installation, the vertical portion is inserted into the annular mounting groove, and the press-fit portion correspondingly closes the annular opening between the two annular side walls, thereby achieving a seal.

[0048] A plurality of outwardly extending abutment support legs 62 are provided on both sides of the seal body 61, and after the seal body 61 is inserted into the annular fitting part, the abutment support legs 62 arranged diagonally on both sides of the seal body 61 can abut against the side walls on both sides of the annular fitting groove. Because the abutment support legs 62 are arranged diagonally, when assembled into the annular fitting groove, they abut against the inner wall of the annular fitting groove, which effectively prevents the seal part from falling or falling off from the first case lid part 51 after assembly into the first case lid part 51.

[0049] The angle between the contact support leg portion 62 and the seal body 61 is 45 to 60 degrees.

[0050] The strain chamber may be diamond-shaped, rectangular, oval, etc. in shape, and after being subjected to pressure, can be pressed flat and have a large contact area with the table surface 100 .

[0051] For example, the strain portion 63 is provided above the press-fit portion, and a strain chamber is formed inside the strain portion 63. Therefore, when the base surface 100 and the first case cover part 51 are assembled, the strain chamber in the strain portion 63 located between the base surface 100 and the first case cover part 51 can be press-fitted by the base surface 100.

[0052] Since the inside of the strain chamber is hollow, the hollow strain chamber can provide a compression space when the base surface 100 is installed, making it easier to press and fix the sealing part into the annular fitting groove of the first case cover part 51 during installation.

[0053] Furthermore, since the distortion chamber in this embodiment is hollow, after it is subjected to the pressure of the base surface 100, the entire distortion portion 63 is pressed flat, changing from a three-dimensional distortion portion 63 to a flat one, thereby increasing the area of ​​the entire distortion portion 63 and increasing the contact area between the base surface 100 and the first case lid part 51, and further enhancing the sealing effect between the base surface 100 and the first case lid part 51, effectively preventing the water vapor in the detergent case from escaping outside through the base surface 100.

[0054] As shown in Figure 11, the second case lid part 52 is provided above the base surface 100, and the second case lid part 52 comprises a second case lid body and an inverted lid body rotatably connected to the second case lid body, and a sealing structure is provided between the second case lid body and the base surface 100.

[0055] A recessed chamber is formed in the top surface of the second case cover so as to be recessed inward, and a rotating shaft is provided on the bottom wall of the recessed chamber.The reversible cover is provided within the recessed chamber and is rotatably connected to the rotating shaft, and can be rotated in an inverted manner to open or close the input opening.

[0056] The above-mentioned sealing structure includes an annular groove formed around the periphery of the second case cover, and an annular seal 7 fitted into the annular groove, the annular seal 7 being an annular seal strip. An annular protrusion 101 is provided on the base surface 100, and the annular protrusion 101 abuts against the bottom of the annular seal 7. After the base surface 100 and the second case cover are connected and fixed, the annular seal 7 on the second case cover is pressed and fixed by the annular protrusion 101 on the base surface 100, thereby realizing a sealed connection between the second case cover and the base surface 100.

[0057] A stopper portion is further provided within the annular groove, and the stopper portion is arranged along the circumferential direction of the annular fitting groove, the height of the stopper portion is smaller than the height of the side wall of the annular groove, and when the annular sealing material 7 is attached at a predetermined position, the stopper portion abuts against the annular sealing material 7. The stopper portion is a support protrusion provided within the annular groove, and is formed by extending from the top wall of the annular groove to the annular attachment opening, and the stopper portion and the annular protrusion portion 101 are provided opposite to each other.

[0058] After the annular seal 7 is installed in the annular groove, it is subjected to the contact force of the stopper portion in the annular groove, and also to the contact force of the annular protrusion 101 located on the base surface 100. The two forces are equal in magnitude but opposite in direction, and the action of the forces of the two components, the stopper portion and the annular protrusion 101, ensures that the annular seal 7 can be firmly fitted into the base surface 100 and the second case cover, resulting in a good sealing effect.

[0059] 6, 12, and 13, the first case lid part 51 is covered by the main body part 2, and water guide channels are formed between the first case lid part 51 and the main body part 2. In this embodiment, the water guide channels include a first water guide channel provided to surround the first housing chamber 111, a second water guide channel provided to surround the second housing chamber 22, and a third water guide channel provided to surround the third housing chamber 23.

[0073] The first case lid part 51 is provided with a third mating flow path 87 that abuts against the third flow path 85, and a fourth mating flow path 88 that abuts against and fits with the fourth flow path 86. The third mating flow path 87 and the third flow path 85 abut against and fit together to form a first abutting flow path, and the fourth flow path 86 abuts against and fits together with the fourth mating flow path 88 correspondingly to form a second abutting flow path, and the first abutting flow path and the second abutting flow path form the third water guide flow path.

[0074] When the water flows in, it first enters the first butt flow passage, flows out from the outlet 851 of the first butt flow passage, and then flows into the second butt flow passages on both sides through the second water inlet notches 861 in the second butt flow passages on both sides into the third storage chamber 23 to dilute the detergent.

[0075] For example, a sixth water-guiding rib 210 is provided around the third storage chamber 23, and one of the fourth flow paths 86 is formed between the inner fifth water-guiding rib 29 and the sixth water-guiding rib 210, and a seventh water-guiding rib 211 is provided opposite the fifth water-guiding rib 29 and is located on the other side of the third storage chamber 23, and another fourth flow path 86 is formed between the seventh water-guiding rib 211 and the sixth water-guiding rib 210.

[0076] The third mating passage 87 and the fourth mating passage 88 located in the first case cover part 51 are also formed by protruding ribs, and the installation method of the protruding ribs is the same as the installation method in the main part 2 to achieve matching.

[0077] The water dividing protrusion 212 is provided on the sixth water guide rib 210, faces the position of the outlet 851, and is used to divide the water flow in the third flow path 85 into two fourth flow paths 86.

[0078] The first water conducting channel, the second water conducting channel and the third water conducting channel are each provided with a water inlet port corresponding to the water conducting channel, through which a water pipe is inserted to transport the water flow into the corresponding water conducting channel.

[0079] In some embodiments of the present application, four water inlet pipes are provided, namely, a first water inlet pipe 91, a second water inlet pipe 92, a third water inlet pipe 93, and a fourth water inlet pipe 94, and when connected, the first water inlet pipe 91 and the second water inlet pipe 92 are inserted into the water inlet portion of the first water conveyance flow path, the third water inlet pipe 93 is inserted into the water inlet portion of the second water conveyance flow path, and the fourth water inlet pipe 94 is inserted into the water inlet portion of the third water conveyance flow path.

[0080] By connecting multiple water channels to multiple different water inlet pipes, cold or hot water can be injected into different chambers according to the needs of the corresponding detergents, thereby meeting the dissolution needs of different detergents and improving the overall washing effect of the laundry treatment device.

[0081] This embodiment further provides a laundry treatment device including a drum and the above-mentioned detergent case, and the laundry treatment device in this embodiment is an industrial laundry treatment device or a home laundry treatment device.

[0082] Example 2 As shown in Figures 14 and 15, this embodiment provides a detergent case, and differs from embodiment 1 in that the water inlet module 3 in this embodiment is provided with a guide plate 301 that is arranged circumferentially around the water inlet 21 and extends into the first storage chamber 111, the guide plate 301 facing the side wall of the first storage chamber 111 is provided with a flow guide surface 302 that is inclined toward the bottom of the first storage chamber 111 and extends to the side wall of the first storage chamber 111, and a second long flow path 312 is formed between the flow guide surface 302 and the guide plate 301 facing it.

[0083] After entering first flow path 81, the water flows in through water inlet 21, flows downward along flow guiding surface 302, and is forced out through second long flow path 312 by the action of guide plate 301, thereby increasing the water pressure of the inflow water to quickly wash away the detergent in first storage chamber 111. The water also directly hits the side wall of first storage chamber 111, thoroughly washing away detergent adhering to the side wall of first storage chamber 111, improving the utilization rate of the detergent and preventing detergent from remaining on the side wall of first storage chamber 111. In addition, the formed second long flow path 312 increases the water outflow pressure and also expands the water outflow area, thereby increasing the area for washing the side wall of first storage chamber 111.

[0084] In this embodiment, by providing multiple water inlets 21 in the first flow path 81 and providing the water inlet module 3 of this embodiment in the water inlets 21, it is possible to ensure that all parts of the side wall of the first storage chamber 111 can be washed.

[0085] In this embodiment, four water inlets 21 are provided, and since the first flow path 81 is arranged to surround the first storage chamber 111, two water inlets 21 are provided in the two opposing straight flow paths of the first flow path 81, and the other two water inlets 21 are provided in the two curves of the first flow path 81, thereby ensuring that all parts of the side wall of the first storage chamber 111 can be washed.

[0086] In this embodiment, the angle between the flow guide surface 302 and the horizontal plane is 45 to 60 degrees, which ensures that the inlet water speed is not affected and maximizes the inlet water pressure. The length of the water inlet 21 is set to 15 to 35 mm, which improves the effectiveness of cleaning the side wall of the first storage chamber 111.

[0087] A water-blocking protrusion 303 is provided on the side of the water inlet 21 facing the direction of water flow.

[0088] The water-blocking protrusion 303 has a certain blocking effect on the water flow attempting to enter the water inlet 21, reducing the flow rate of the water flow and preventing the water flow from being too fast and flowing directly into the first storage chamber 111 from above the water outlet, and the water-blocking protrusion 303 ensures that the water flow flows down from the water inlet 21.

[0089] Other structures of the detergent case according to this embodiment are the same as those of the first embodiment.

[0090] This embodiment further provides a laundry treatment device comprising a drum and the detergent case described in the above embodiment, and the laundry treatment device in this embodiment is an industrial laundry treatment device or a domestic laundry treatment device.

[0091] Example 3 This embodiment provides a detergent case, which differs from embodiments 1 and 2 in that in this embodiment, multiple water inlets 21 are provided in the first flow path 81, and water inlet modules 3 are provided in the water inlets 21, some of which have the structure of the water inlet modules 3 according to embodiment 1, and other parts of which have the structure of the water inlet modules 3 according to embodiment 2, and by using both in combination, the effect of the water flow in washing the side walls of the first storage chamber 111 is improved.

[0092] For example, the first flow path 81 is arranged to surround the first storage chamber 111, and water inlets 21 are provided in two opposing vertical straight flow paths of the first flow path 81, and the water inlet module 3 at the water inlets 21 may have the structure of the water inlet module 3 according to Example 2. A water inlet 21 is provided in the middle of the horizontal straight flow path connecting the two vertical straight flow paths, and the water inlet module 3 at the water inlet 21 may have the structure of the water inlet module 3 according to Example 1, thereby enabling the three side walls of the first storage chamber 111 to be washed.

[0093] Other structures of the detergent case according to this embodiment are the same as those of the first embodiment.

[0094] This embodiment further provides a laundry treatment device comprising a drum and the detergent case described in the above embodiment, and the laundry treatment device in this embodiment is an industrial laundry treatment device or a domestic laundry treatment device.
