Description

Technical Field

[0001] The utility model belongs to the field of industrial washing machine equipment, in particular to a visible liquid adding system for a washing machine dispenser. Background Art

[0002] Large industrial washing machines distribute various detergents entering the washing machine through a dispenser. Each detergent entering the washing machine is drawn from the detergent container by a pump and directly enters the dispenser pipe, and then enters the washing machine. The required amount of detergent entering the washing machine is issued by the washing machine control system. The automatic control system controls the running time of the pump and determines the required amount of detergent according to the flow rate and running time of the pump. If the user needs to confirm the amount of various detergents entering, one method is to calculate according to the flow rate and running time of the pump. The pump will be calibrated before running. During calibration, the detergent needs to be measured with a measuring cup and divided by the running time of the pump to obtain the flow rate of the pump. The automatic control system program controls the amount of detergent entering the washing machine according to the running time of the controlled pump. When the user confirms, the amount of detergent entering the washing machine needs to be obtained by multiplying the running time of the pump by the flow rate of the pump; the second is to measure the remaining liquid in the container containing various detergents, and subtract the remaining amount from the total capacity to obtain the amount of detergent entering the washing machine. Both methods cannot intuitively see how much liquid the pump extracts each time, which is time-consuming and labor-intensive. In addition, the pressure in the distribution valve pipeline affects the flow rate at the pump outlet, which slows down the speed of adding the medicine. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a visible liquid adding system for a washing machine dispenser.

[0004] The technical solution of the utility model is implemented as follows: a visual liquid adding system for a washing machine dispenser, comprising a pump, the pump is connected to a medicine barrel, the pump is connected to the lower part of a closed container through a pipe one, the pipe one is three-way connected to a distribution valve pipe, a one-way valve two and a one-way valve one are respectively provided on the pipe one and the distribution valve pipe, the closed container is transparent, a scale is provided on the closed container, the upper part of the closed container is three-way connected to valve one and valve two, the valve one is connected to compressed air, and the valve two is connected to the external atmosphere.

[0005] The beneficial effects of the utility model are as follows: the utility model provides a transparent closed container with a scale, first draws the detergent into the transparent closed container with a scale, and uses the pressure of compressed air to pump it into the distribution valve pipeline, which is convenient for the user to read each time.

[0008] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0009] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0010] See attached Figure 1 A visual liquid adding system for a washing machine dispenser, comprising a pump 8, wherein the pump 8 is connected to a medicine barrel 6, wherein the pump 8 is connected to a lower portion of a closed container 5 via a pipe 9, wherein the pipe 9 is three-way connected to a distribution valve pipe 7, wherein a check valve 4 and a check valve 3 are respectively arranged on the pipe 9 and the distribution valve pipe 7, wherein the closed container 5 is transparent and has scales, wherein an upper portion of the closed container 5 is three-way connected to a valve 1 and a valve 2 2, wherein the valve 1 is connected to compressed air, and the valve 2 2 is connected to the external atmosphere.

[0011] Working principle and steps: Check valve 1 3 and check valve 2 4 are check valves. Liquid needs a certain pressure to start flowing in the forward direction, but cannot flow in the reverse direction. Valve 1 1 and valve 2 2 are switch valves. Valve 1 1 and valve 2 2 can also be replaced by a three-way valve. The closed container 5 is transparent and has a scale 51. The upper and lower openings are connected to the valve pipeline. The liquid in the medicine barrel 6 is for pump 8 to extract. When working, first open valve 2 2, close valve 1, and start pump 8 for a fixed time. Pump 8 extracts liquid from the medicine barrel 6 and flows into the transparent closed container 5 through check valve 2 4. Pump 8 stops, and the liquid level of the closed container 5 can be seen. At this time, close valve 2 2, open valve 1 1, and compressed air 10 enters the closed container 5 through valve 1 1. Under the action of high-pressure air, the liquid in the closed container 5 is quickly pressed into the distribution valve pipeline 7 through the check valve 1 3. By setting up a transparent closed container with a scale, the detergent is first drawn into the transparent closed container with a scale, and then pumped into the distribution valve pipe using the pressure of compressed air, which is convenient for the user to read each time. When the pump is calibrated, the liquid pumped out at a fixed time can also be read intuitively. The flow rate can be obtained by dividing it by the running time of the pump. This eliminates the need for drawing with a measuring cup, saving time and effort, while improving the accuracy of agent addition, reducing the outlet resistance of the pump, and making addition faster.

[0012] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
