Description

Technical Field

[0001] This utility model relates to the field of washing machine technology, and in particular to a double-drum washing machine casing. Background Technology

[0002] A double-drum washing machine is a type of washing machine with a twin-drum structure. It has two drums inside the washing drum, and the two drums can work independently. Double-drum washing machines can be divided into two-section and three-section types. Two-section double-drum washing machines include a washing drum and a spin-drying drum, while three-section double-drum washing machines also include a drying drum. In three-section double-drum washing machines, the drying drum can use electric heating or gas heating to dry clothes.

[0003] Washing machines typically have internal counterweights, some of which are fitted onto the drum to increase the machine's weight and help stabilize the casing during operation. However, double-drum washing machines are quite tall, and when only the top drum is used for rotation, the casing is prone to wobbling because its center of gravity is close to the top. The top counterweights also experience strong shaking due to the centrifugal force of rotation, causing the casing to deform under the stress of the shaking and damaging its structural strength. Therefore, a double-drum washing machine casing is proposed. Utility Model Content

[0027] Embodiments

[0028] Refer toFigures 1-4 For an embodiment of the utility model, provide a kind of complex drum washing machine shell, comprising: support unit 100 and counterweight unit 200;

[0029] Wherein, support unit 100 includes shell 101 and the access hole 102 being opened in the both sides of shell 101, the inner wall of two access holes 102 is slidably provided with cover plate 103, and two cover plates 103 are fixedly connected in the inside of two access holes 102 respectively by bolt;

[0030] Counterweight unit 200 includes water tank 201 being fixedly connected in the bottom of the inner chamber of shell 101, and the water tank 201 side is fixedly communicated with the water inlet pipe 202 that penetrates shell 101, and the top of water tank 201 is fixedly communicated with water supply pipe 203, and the bottom end of water supply pipe 203 extends to the bottom of the inner chamber of water tank 201, and the bottom end of water supply pipe 203 and the bottom of the inner chamber of water tank 201 leave gap, and the inner chamber of water tank 201 is vertically slidably provided with floating plate 204, and water supply pipe 203 vertically penetrates floating plate 204, and the inner wall of water tank 201 is fixedly connected with limit block 205.

[0031] Cover plate 103 on the both sides of shell 101 can be fixed in two access holes 102 by bolt, and two cover plates 103 can be removed from two access holes 102 by taking out bolt, so that the parts inside shell 101 are maintained and checked, water inlet pipe 202 is used to supply water to water tank 201, and water supply pipe 203 is used to supply water to drum, when washing machine is not used, no clean water is stored in the inside of water tank 201, to reduce the bearing load of shell 101, and reduce the deformation of shell 101, when washing machine is used to wash clothes, water tank 201 is filled with clean water by water inlet pipe 202, when water supply pipe 203 supplies water to drum, water inlet pipe 202 continuously supplies water to the inside of water tank 201, to ensure that water tank 201 is in full load state, the weight of shell 101 is increased by water tank 201, and the weight is concentrated on the bottom of shell 101, when washing machine operates, shell 101 can automatically increase weight and keep operating stable;

[0032] Thus, the use of counterweights can be reduced, and when the top drum rotates, the shell 101 can still improve the stability of the support, the floating plate 204 can float on the water surface of the water tank 201, and the height of the floating plate 204 cannot be lower than the water inlet pipe 202 through the limiting block 205. When the water amount in the water tank 201 increases or decreases, the floating plate 204 vertically slides in the water tank 201, the washing machine moves in a rotating state, so that the shell 101 does not generate a vertical force, thereby ensuring that the floating plate 204 is tightly attached to the water surface, avoiding the water surface from being disturbed, thereby improving the stability of the shell 101, reducing the shaking of the shell 101, and improving the service life of the shell 101. After use, the water in the water tank 201 can be discharged through the water inlet pipe 202 to reduce the weight of the shell 101. During water interruption, the water in the water tank 201 can be stored in the water tank 201 for emergency use of the washing machine.

[0033] In addition, the top of the water tank 201 is fixedly connected with a plurality of S-shaped plates 206 penetrating the floating plate 204. Each S-shaped plate 206 is arranged in an inclined manner, and the side wall of each S-shaped plate 206 is provided with a plurality of circular holes.

[0034] The plurality of S-shaped plates 206 are arranged in a forty-five-degree inclined manner in the water tank 201. The bottom of the S-shaped plate 206 is spaced from the bottom of the inner cavity of the water tank 201, so that the clean water can flow in the water tank 201. The connection between the floating plate 204, the S-shaped plate 206 and the water supply pipe 203 is sealed. The floating plate 204 can vertically slide along the S-shaped plate 206 and the outer wall of the water supply pipe 203. When the drum rotates, the shell 101 and the water tank 201 are subjected to the action of the rotating force, which causes the clean water below the floating plate 204 to slightly shake. The S-shaped plate 206 can guide and disperse the shaking and impact force of the clean water from any plane direction. The S-shaped arrangement can greatly buffer the impact force of the clean water, and part of the clean water can pass through the S-shaped plate 206 to reduce the impact force on the S-shaped plate 206. The plurality of S-shaped plates 206 can reduce the shaking of the clean water in the water tank 201, thereby improving the stability of the shell 101.

[0035] The top of the water tank 201 is threadedly connected with a threaded rod 207 penetrating the water tank 201. The bottom end of the threaded rod 207 is fixedly connected with a rubber pad 208. The bottom of the water supply pipe 203 is fixedly sleeved with a filter cylinder 209. The bottom of the filter cylinder 209 is fixedly connected to the bottom of the inner cavity of the water tank 201.

[0036] The height of the floating plate 204 can be limited by rotating the threaded rod 207. When only a single drum is used for washing, the threaded rod 207 is rotated to start lowering the height of the bottom end, and thus the height of the floating plate 204 is limited by the threaded rod 207. The floating plate 204 can be protected by the rubber pad 208 to avoid damage caused by repeated impact of the floating plate 204 on the threaded rod 207. Thus, the water storage capacity inside the water tank 201 can be reduced, the water tank 201 can be quickly filled with water, and the water supply speed to the drum can be improved. The clean water in the water tank 201 can be filtered by the filter cylinder 209 to ensure the cleanliness of the water supplied by the water supply pipe 203.

[0037] Further, the inner wall of the shell 101 is fixedly connected with a plurality of evenly distributed fireproof plates 104 by bolts. One side of each fireproof plate 104 is fixedly connected with soundproof cotton 105 tightly attached to the inner wall of the shell 101.

[0038] The fireproof plate 104 is made of a material added with a fire-retardant material. When a fire breaks out inside the shell 101, the fireproof plate 104 can retard the flame to protect the shell 101. The soundproof cotton 105 can be laid on the inner wall of the shell 101 by the fireproof plate 104. The noise generated by the rotation of the drum can be reduced by the soundproof cotton 105, and the propagation of sound can be weakened to reduce the vibration of the shell 101 caused by sound.

[0039] Still further, the inner wall of the shell 101 is fixedly connected with a plurality of reinforcing blocks 106 by bolts. Each reinforcing block 106 is located at an angle of the inner cavity of the shell 101.

[0040] The reinforcing block 106 is triangularly arranged and can reinforce both sides of the inner wall of the shell 101 to improve the support force of the shell 101 and reduce the bending of the shell 101. The overall strength of the shell 101 can be improved by the reinforcing block 106.

[0041] During use, the two cover plates 103 can be removed from the two access openings 102 by taking out the bolts. Then the height of the floating plate 204 can be limited by rotating the threaded rod 207 to increase the water storage capacity inside the water tank 201. After adjustment, the cover plate 103 is reinstalled into the access opening 102. When the washing machine is used for washing, the water inlet pipe 202 is connected to a water source and the water tank 201 is filled with clean water. Then the clean water in the water tank 201 is supplied to the drum by the water supply pipe 203. The weight of the shell 101 is increased by the water tank 201, and the weight is concentrated at the bottom of the shell 101 to ensure the stability of the shell 101. The water surface is tightly attached to the floating plate 204 to avoid fluctuations in the water surface. The S-shaped plates 206 can reduce the shaking of the clean water inside the water tank 201 to improve the stability of the shell 101.

[0042] When using is finished, the water in the water tank 201 can be discharged through the water inlet pipe 202 to reduce the weight of the shell 101, and the water in the water tank 201 can be stored in the water tank 201 during water interruption to provide emergency use for the washing machine to wash clothes, the inside of the shell 101 can be installed with the fireproof plate 104, the sound insulation cotton 105 and the reinforcing block 106 through bolts, the flame in the inside of the shell 101 can be prevented from burning through the fireproof plate 104, the noise generated by the rotation of the drum can be reduced through the sound insulation cotton 105, and the vibration generated by the sound to the shell 101 can be reduced, and the supporting force and the strength of the shell 101 can be improved through the reinforcing block 106.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, not to limit it. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
