AI Technical Summary
The uneven addition of additives in existing washing machines leads to a decrease in washing effect, and manual addition is costly and prone to errors.
A feeding device for a washing machine was designed. It uses a peristaltic pump to deliver additives in a timed and quantitative manner. After mixing with water in the washing machine tank through the inlet pipe, the additives are sent to the spray pipe by a circulating pump for uniform spraying. Combined with a filter screen to filter impurities, it ensures that the additives are evenly distributed.
This method achieves uniform addition of additives, reduces manual operation costs, improves the washing effect, and ensures uniform mixing of additives.

Abstract
Description
Technical Field
[0001] This utility model relates to a feeding device, and more particularly to a feeding device for a washing machine. Background Technology
[0002] Rope washing machines involve immersing fabrics in the machine for washing. Various auxiliaries, such as fabric softeners, are added to the water tank. However, as the washing process progresses, the concentration of these auxiliaries in the tank decreases, affecting the washing effect. Therefore, auxiliaries need to be continuously added. However, directly adding auxiliaries to the tank results in uneven distribution of the auxiliaries due to the poor water flow, which is also detrimental to the washing operation. Furthermore, the need for continuous addition increases labor costs if done manually and increases the risk of errors. Utility Model Content
[0003] To overcome the above-mentioned shortcomings, this utility model provides a feeding device for a washing machine, which can add additives to the washing machine evenly at regular intervals and in quantitative amounts.
[0004] To achieve this objective, the structure adopted by this utility model is as follows: a water washing machine feeding device, including a box body, one or more peristaltic pumps are provided on the top of the box body, the peristaltic pumps are connected to the auxiliary agent tank and the box body through pipes, a water inlet pipe is provided on the side of the box body, and a water outlet is connected to the bottom of the box body through a circulation pump.
[0005] One or more filter screens are installed in the center of the box, dividing the box into left and right sides. The water inlet pipe is located on the left side of the box, and the water outlet is connected to the right side of the box.
[0006] A ball valve is installed at the bottom of the box.
[0007] The water outlet is connected to the spray pipe.
[0008] A support frame is provided at the bottom of the box.
[0009] Its beneficial effects are: the structure of this utility model is reasonable and ingenious. The water inlet pipe is connected to the water outlet pipe of the washing machine, and the water outlet is connected to the spray pipe set at the top of the washing machine through the pipe. The peristaltic pump delivers the auxiliary agent into the tank through the pipe at regular intervals and in quantitative amounts. The water in the washing machine enters the tank and mixes with the auxiliary agent. The mixture is pumped into the spray pipe by the circulation pump for uniform spraying. It can accurately control the amount of auxiliary agent added, reduce labor costs, and facilitate the uniform mixing of the auxiliary agent in the washing machine. Attached Figure Description
[0010] This utility model will be described by way of example and with reference to the accompanying drawings, wherein:
[0011] Figure 1 This is the front view of this utility model;
[0012] Figure 2This is a side view of the present invention;
[0013] Figure 3 This is a diagram showing the connection between this utility model and a washing machine. Detailed Implementation
[0014] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0015] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components; a fixed connection can be welding or adhesive bonding. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0017] like Figure 1 , Figure 2 The washing machine feeding device shown includes a housing 1. One or more peristaltic pumps 6 are installed on the top of the housing 1. Each peristaltic pump 6 is connected to an auxiliary agent tank 7 and the housing 1 via a pipe, and the peristaltic pumps 6 deliver the auxiliary agent into the housing 1 in a timed and metered manner. A water inlet pipe 2 is installed on the bottom side of the housing 1. Figure 3 As shown, the inlet pipe 2 is connected to the outlet pipe 11 of the washing machine 10 through a pipe, introducing water from the water tank of the washing machine 10 into the tank 1 to mix evenly with the additives. The bottom of the tank is connected to the outlet 4 through the circulation pump 3, and the outlet 4 is connected to the spray pipe 9. The water that is evenly mixed with the additives is pumped back into the washing machine 10 through the circulation pump 3 and sprayed evenly into the water tank through the spray pipe 9.
[0018] One or more filter screens 8 are installed in the center of the housing 1. The filter screens 8 are connected to the housing 1 via connectors, dividing the housing 1 into left and right sides. The water inlet pipe 2 is located on the left side of the housing 1, and the water outlet 4 is connected to the right side of the housing 1. Since the water in the washing machine 10 contains floating hair and impurities, the filter screens 8 prevent these impurities from entering the circulation pump 3. The filter screens 8 are connected using detachable connectors, including bolts, slots, and other structures, for easy disassembly and cleaning of the filter screens 8.
[0019] A ball valve 5 is provided at the bottom of the box 1, which connects the box 1 to facilitate emptying of the box 1.
[0020] The bottom of the housing 1 is provided with a support 3. The height of the support 3 is the same as the height of the water tank of the washing machine 10. This can ensure that the liquid level in the water tank of the washing machine 10 is the same as the liquid level in the water tank 1, and prevent water from overflowing from the water tank. At the same time, the circulation pump 3 can be integrated into the overhead space at the bottom of the housing 1, reducing the exposed structure of the device and preventing the pipes from becoming loose due to collision.
[0021] This utility model has a reasonable and ingenious structural design, which can accurately control the amount of additives added, reduce labor costs, and facilitate the uniform mixing of additives in the washing machine.
[0022] Based on the above description and inspired by this utility model, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
