[0025] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0026] Reference Figures 1 to 4 As shown, a four-door drum with detachable discharge racks is provided, including a drum body 1 with a washing chamber 11 inside. Several discharge racks 2 are detachably installed inside the drum body 1, and the discharge racks 2 divide the washing chamber 11 into two parts. Four drum doors 3 are movably installed on the drum body 1 by hinges, and the four drum doors 3 are symmetrically arranged on the drum body 1.

[0027] In this embodiment, the washing chamber 11 inside the drum body 1 is divided into two parts by the discharge rack 2. When the drum body 1 stops rotating, the clothes fall onto the discharge rack 2. The user only needs to take the clothes out of the discharge rack 2. There is no need to bend over and reach into the drum to take out the clothes at the bottom. The work is relatively easy and not strenuous. At the same time, the drum body 1 is provided with four drum doors 3, which can take out and put in clothes from the four drum doors 3 at the same time, improving efficiency.

[0028] Preferably, the discharge rack 2 is made of carbon fiber material. Carbon fiber has the characteristics of being lightweight and highly corrosion-resistant. When disassembling, it is easy for users to take it out without increasing their labor intensity. At the same time, when the washing chamber 11 washes clothes, it will put in a large number of chemicals, which will corrode the discharge rack 2. However, carbon fiber is not easily affected and its service life is extended.

[0029] In one embodiment of this utility model, each of the four drum doors 3 is provided with a number of evenly distributed drainage holes 31 to prevent water from easily accumulating in certain positions inside the drum body 1. During the rotation of the drum body 1, water can be drained from all directions without angles, reducing the weight of the user carrying wet clothes and reducing labor intensity.

[0030] In one embodiment of this utility model, the discharge rack 2 includes a rectangular frame 21, two horizontal bars 22 and four vertical bars 23. The horizontal bars 22 and vertical bars 23 are perpendicular to each other and intersect within the rectangular frame 21. The two horizontal bars 22 and four vertical bars 23 evenly divide the rectangular frame 21 into fifteen sections. One end of each of the four vertical bars 23 is connected to the inner side of the rectangular frame 21, and the other end of each of the four vertical bars 23 passes through the two horizontal bars 22 and connects to the inner side of the rectangular frame 21. The fifteen sections do not allow clothes to pass through, but allow water from wet clothes to pass through and fall onto the inner wall of the roller body 1, reducing the weight of the wet clothes for the user and reducing labor intensity.

[0031] In one embodiment of this utility model, the end of the cylindrical door 3 away from the hinge is provided with two symmetrically arranged mounting grooves 32, and a switch 4 is provided on the mounting grooves 32. A groove for easy handle is also provided between the two mounting grooves 32. The switch 4 is used to lock the cylindrical door 3.

[0032] Furthermore, the switch 4 includes a spring 41 and an H-shaped rod 42. One end of the H-shaped rod 42 abuts against the inner wall of the mounting groove 32 through the spring 41, and the other end of the H-shaped rod 42 protrudes outward from the inner wall of the mounting groove 32 on the other side to facilitate locking the cylinder door 3. A limit block 43 is fixedly provided at the end of the H-shaped rod 42 near the spring 41. Through holes are opened on both sides of the cylinder door 3 for one end of the H-shaped rod 42 to pass through. Under the action of the spring 41, the end of the H-shaped rod 42 without the spring 41 can extend and retract into and out of the through hole to achieve the effect of locking or unlocking. The limit block 43 is to prevent one end of the H-shaped rod 42 from protruding excessively from the through hole, causing the middle crossbar of the H-shaped rod 42 to be tightly pressed against the inner wall of the mounting groove 32, making it inconvenient to unlock.

[0033] In one embodiment of this utility model, four evenly distributed V-shaped supports 12 are provided on the inner wall of the roller body 1. The inner diameter of the roller body 1 is slightly larger than the length of the discharge rack 2. The discharge rack 2 is detachably installed on one side of the V-shaped supports 12. The wider side of the discharge rack 2 first enters the interior of the roller body 1, and then reaches the designated position, fitting and locking against the inner wall of the roller body 1. When the roller body 1 rotates, the discharge rack 2 will not fall to the bottom of the roller body 1, but will move slightly on one side of the V-shaped supports 12. Figure 4 As shown, the 180° tumbling roller body 1 allows the discharge rack 2 to fall onto the two V-shaped supports 12, preventing the discharge rack 2 from undergoing excessive displacement and thus damaging it.

[0034] In one embodiment of this utility model, a plurality of evenly distributed water passage holes 13 are provided on the roller body 1 to facilitate the leakage of water from wet clothes from the roller body 1, thereby reducing the weight of the user carrying wet clothes and reducing labor intensity.

[0035] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
