Description

Technical Field

[0001] This utility model relates to fabric cleaning equipment, and more particularly to a fabric washing machine. Background Technology

[0002] Fabric cleaning machines are cleaning devices used to clean clothes or fabrics. Their brush head is connected to two pipes: one for spraying clean water containing detergent, and the other for recovering the wastewater stream after the cleaning process via negative pressure. Therefore, the main unit of a fabric cleaning machine typically has a clean water tank and a wastewater tank. To ensure cleaning effectiveness, the clean water tank needs to be cleaned regularly. Because the clean water tank is mounted on the main unit, it is inconvenient to invert it for cleaning and must be removed for cleaning. Furthermore, after long-term use, detergent and limescale residue easily accumulates in the clean water tank, making cleaning inconvenient. Utility Model Content

[0003] In view of the above-mentioned problems in the prior art, a fabric cleaning machine is provided to facilitate the cleaning of the water tank to remove residual detergent and limescale, thereby overcoming at least one of the above-mentioned technical defects.

[0004] The specific technical solution is as follows: A fabric cleaning machine, comprising: The main body has a clean water tank, a waste water tank, and a handle assembly. The clean water tank has an opening, and one end of the handle assembly is connected to the waste water tank via a waste water pipe, while the other end has a brush head. The self-cleaning cover can be fitted onto the clean water tank and close the opening. The self-cleaning cover has a suction tube that extends into the clean water tank. The self-cleaning cover also has a receiving groove, in which the brush head can be at least partially disposed. Furthermore, in the self-cleaning working state, the liquid flow in the clean water tank can flow to the wastewater tank through the suction pipe, self-cleaning cover, handle assembly, and wastewater pipe under the negative pressure of the brush head, so as to perform the self-cleaning function of the clean water tank.

[0005] Preferably, the receiving groove is formed on the upper end face of the self-cleaning cover and is adapted to the shape of the brush head, and at least one inner sidewall of the receiving groove is configured as an inwardly converging slope to prevent the brush head from freely detaching after being inserted into the receiving groove.

[0006] Preferably, the self-cleaning cover is made entirely of soft rubber material, and when the brush head is inserted into the receiving groove, at least two inner sidewalls of the receiving groove are in close contact with the outer surface of the brush head, causing the brush head to be held in the receiving groove.

[0007] Preferably, a snap-fit ​​structure is formed between the inner bottom surface of the receiving groove and the outer wall of the brush head; or, The receiving groove also has a locking member to prevent the brush head from coming out, so that the brush head is stuck in the receiving groove.

[0008] Preferably, the lower end face of the self-cleaning cover has a through hole communicating with the receiving groove, and a water suction pipe is inserted through it; or, The suction tube is integrally molded onto the self-cleaning cover, and the suction tube connects to the receiving slot and extends downwards.

[0009] Preferably, the fabric cleaning machine also includes a water tank cover that can be fitted onto the clean water tank and close the opening. The water tank cover serves as the first accessory in the working state of cleaning clothes or fabrics, and the self-cleaning cover serves as the second accessory in the working state of self-cleaning.

[0010] Preferably, a first stepped surface is also formed in the receiving groove to support the brush head, resulting in a gap between the bottom surface of the brush head and the inner bottom surface of the receiving groove.

[0011] Preferably, the lower end face of the self-cleaning cover also forms a second stepped surface, which abuts against the upper edge of the opening of the clean water tank and prevents the entire self-cleaning cover from falling into the clean water tank.

[0012] Preferably, the upper surface of the water tank cap also has a gripping part.

[0013] Preferably, the outer wall of the water tank cover has at least one retractable latch for extending into the opening to lock the connection of the fresh water tank, and the water tank cover has a button for controlling the inward retraction of the latch.

[0014] The beneficial effects of the above technical solution are as follows: The fabric cleaning machine includes a main body, a clean water tank, a wastewater tank, a handle assembly, a wastewater pipe, a self-cleaning cover, and a suction pipe. The self-cleaning cover can be placed on the clean water tank and connected to the brush head, allowing the liquid in the clean water tank to be drawn into the wastewater tank, completing the self-cleaning action of the clean water tank.

[0021] To make the technical means, creative features, achieved objectives and effects of this utility model easier to understand, the following embodiments are described in detail with reference to the accompanying drawings. And the following definitions are provided: Figure 2 The up-down direction shown on the paper is the up-down direction in this embodiment.

[0022] See Figures 1 to 6 As shown in the figure, the fabric cleaning machine provided in this embodiment includes: The main body 1 has a clean water tank 2, a wastewater tank 3, and a handle assembly 4. The clean water tank 2 has an opening 9. One end of the handle assembly 4 is connected to the wastewater tank 3 via a wastewater pipe, and the other end has a brush head 5. The self-cleaning cover 6 can be fitted onto the clean water tank 2 and close the opening 9. The self-cleaning cover 6 has a suction pipe 7 that extends into the clean water tank 2. The self-cleaning cover 6 also has a receiving groove 10, so that the brush head 5 can be at least partially placed into the receiving groove 10. Furthermore, in the self-cleaning working state, the liquid flow in the clean water tank 2 can flow to the wastewater tank 3 through the suction pipe 7, self-cleaning cover 6, handle assembly 4, and wastewater pipe under the negative pressure of the brush head 5, so as to perform the self-cleaning function of the clean water tank 2.

[0023] Based on the above technical solution, the fabric cleaning machine includes a main body 1, a clean water tank 2, a wastewater tank 3, a handle assembly 4, a wastewater pipe, a self-cleaning cover, and a suction pipe 7. The self-cleaning cover 6 can be placed on the clean water tank 2 and connected to the brush head 5, so that the liquid in the clean water tank 2 can be sucked into the wastewater tank 3 to complete the self-cleaning action of the clean water tank 2, thereby facilitating the cleaning of the clean water tank 2, removing residual detergent and scale, and the overall structure is simple and easy to implement.

[0024] In a preferred embodiment, a receiving groove 10 is formed on the upper end face of the self-cleaning cover 6 and is adapted to the shape of the brush head 5. At least one inner sidewall of the receiving groove 10 is configured as an inwardly converging slope 12 to prevent the brush head 5 from freely exiting the receiving groove 10 after it has been inserted into it. Furthermore, the self-cleaning cover 6 is made entirely of soft rubber material, and when the brush head 5 is inserted into the receiving groove 10, at least two inner sidewalls of the receiving groove 10 are tightly attached to the outer surface of the brush head 5, causing the brush head 5 to be held in place within the receiving groove 10.

[0025] Specifically, the structure of the conventional brush head 5 is usually designed to be gradually expanding, so that its outer wall forms a gradually expanding slope or arc surface. In this solution, this design is used to limit the brush head 5 by the wall of the receiving groove 10.

[0026] As another optional embodiment, a snap-fit ​​structure is formed between the inner bottom surface of the receiving groove 10 and the outer wall of the brush head 5. Alternatively, the receiving groove 10 may also have a locking member to prevent the brush head 5 from coming out, so that the brush head 5 is snapped in the receiving groove 10. Specifically, the former can be achieved by a snap-fit ​​groove structure or a stop structure, while the latter can be achieved by additionally setting a holding member, a baffle, or a pin structure, and is not limited to these.

[0027] In a preferred embodiment, combined with Figure 5 and Figure 6 As shown, the lower end face of the self-cleaning cover 6 has a through hole 11 communicating with the receiving groove 10, and a water suction pipe 7 is inserted through it; or, the water suction pipe 7 is integrally formed on the self-cleaning cover 6, and the water suction pipe 7 communicates with the receiving groove 10 and extends in a downward direction. That is, the water suction pipe 7 and the self-cleaning cover 6 can be an integral or separate structure.

[0028] As a further preferred embodiment, the fabric cleaning machine also includes a water tank cover 8 that can be fitted onto the clean water tank 2 and close the opening 9. The water tank cover 8 serves as a first accessory in the working state of cleaning clothes or fabrics, and the self-cleaning cover 6 serves as a second accessory in the working state of self-cleaning.

[0029] In practical applications, the working state of cleaning clothes or fabrics is basically the same as the existing solution. The water tank cover 8 is covered on the clean water tank 2 as the first accessory. The handle assembly 4 is connected to the clean water tank 2 through the clean water pipeline and water pump to spray clean water mixed with detergent at the brush head 5. The handle assembly 4 is also connected to the wastewater tank 3 through the wastewater pipeline and suction fan to create negative pressure at the brush head 5 and return the wastewater generated after cleaning clothes or fabrics to the wastewater tank 3.

[0030] In self-cleaning mode, the water tank cover 8 needs to be removed first. Optionally, detergent can be injected into the clean water tank 2, and the self-cleaning cover 6 can be installed accordingly. The suction pipe 7 extends into the clean water tank 2; that is, the self-cleaning cover 6 replaces the water tank cover 8 as a second accessory. The brush head 5 is inserted into the self-cleaning cover 6, forming a liquid flow path between the clean water tank 2, the self-cleaning cover 6, the brush head 5, the handle, the sewage pipe, and the sewage tank 3. Under the action of the suction fan, a negative pressure is created on the brush head 5, transporting the liquid in the clean water tank 2 to the sewage tank 3 through this flow path, thus completing the self-cleaning action. After completion, the self-cleaning cover 6 can be replaced back into the water tank cover 8, which is convenient and reliable. It is worth noting that, as a conventional method, the sewage pipe and the clean water pipe are configured in the same corrugated pipe to achieve the purpose of pipe consolidation; that is, the boiler shown in the figure uses a corrugated pipe.

[0031] In a preferred embodiment, a first stepped surface 13 for supporting the brush head 5 is formed within the receiving groove 10, resulting in a gap between the bottom surface of the brush head 5 and the inner bottom surface of the receiving groove 10. Furthermore, the lower end surface of the self-cleaning cover 6 is also formed with a second stepped surface 14, which abuts against the upper edge of the opening 9 on the clean water tank 2 and prevents the self-cleaning cover 6 from falling entirely into the clean water tank 2. Furthermore, the upper end surface of the water tank cover 8 is also formed with a gripping part 15 for easy upward removal. Furthermore, the outer wall of the water tank cover 8 has at least one retractable locking tongue 16 for extending into the opening 9 to lock the connection to the clean water tank 2, and the water tank cover 8 has a button for controlling the inward retraction of the locking tongue. This facilitates insertion into the opening 9 for locking and unlocking, and subsequent removal. The specific structure uses a locking tongue with a spring and a lever, which is not a key design feature of this solution and is therefore omitted here.

[0032] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
