Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of liquid distributors for laundry rooms, specifically a wall-mounted, one-to-four liquid distributor for laundry rooms. Background Technology
[0002] Automatic detergent dispensing has become a standard practice in large-scale cleaning operations such as laundries. Liquid dispensers are typically used to add detergents and distribute the liquids. Different types of detergents are usually added during the washing process, and multiple washing machines can be dispensed simultaneously. The dispenser uses a pump to draw various liquids into the dispenser for distribution. Existing laundry dispensers consist of a pump body and a controller, which controls the washing machine program and the amount of detergent added.
[0003] Current distributor systems sometimes use one distributor to dispense chemicals from one washing machine. This system requires a large number of distributors and chemical storage tanks, causing inconvenience in management, waste of resources, and affecting production efficiency. Other distributor systems use a peristaltic pump to dispense chemicals from one distributor to multiple washing machines. The discharge solenoid valve only has two simple control methods: open and close. It does not have a water shortage feedback detection device, which may scorch clothes and seriously affect the washing effect. Utility Model Content
[0004] This utility model provides a wall-mounted, one-to-four laundry room liquid distributor, which aims to solve the problems mentioned in the background art, such as the lack of a water shortage feedback detection device, which may cause clothes to be scorched and seriously affect the washing effect.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a wall-mounted one-to-four laundry room liquid distributor, comprising a wall-mounted panel and a control box and a laundry detergent dispensing assembly fixedly installed on the wall-mounted panel; the control box has a touch screen on its surface; the laundry detergent dispensing assembly includes a pump fixedly installed on the wall-mounted panel, a first pipe fixedly connected to the inlet of the pump, a second pipe fixedly connected to the outlet of the pump and equipped with a one-way valve, a water shortage protection mechanism fixedly installed at the lower end of the second pipe, a water inlet pipe fixedly connected to one side of the second pipe, and a water inlet pipe fixedly installed on the wall-mounted panel. The second pipe has a detergent dispensing pipe at its upper end; the water shortage protection mechanism includes a water injection chamber fixedly connected to the lower end of the second pipe, a transparent U-shaped tube fixedly connected to one side of the water injection chamber, a floating component disposed inside the transparent U-shaped tube, a pull rope with its two ends fixedly connected to the bottom of the inner wall of the transparent U-shaped tube and the surface of the floating component respectively, and a photoelectric sensor fixedly installed between the outer wall of one side of the water injection chamber and the transparent U-shaped tube. The floating component is spherical or cylindrical and has a density less than that of water. The output end of the photoelectric sensor is electrically connected to the input end of the control box, and the output end of the control box is electrically connected to the input end of the pump.
[0006] During operation, the main control valve is opened via the control box, and clean water is added to the water injection chamber through the water inlet pipe and four branch pipes. At this time, the transparent U-shaped tube is filled with clean water, and the floating part rises under the action of its own buoyancy and is detected by the photoelectric sensor. The photoelectric sensor then transmits an electrical signal to the control box, which starts the pump. The pump then draws laundry detergent from the first pipe and delivers laundry detergent to the laundry detergent distribution pipe from the second pipe, thus delivering laundry detergent to the washing machine. By detecting water shortage and feeding back to the control box, the machine prevents clothes from being scorched.
[0007] Preferably, the touchscreen has 20 built-in washing programs.
[0008] Preferably, the pump is a multi-channel peristaltic pump capable of precisely controlling the amount of material used.
[0009] Preferably, four laundry detergent distribution branches are fixedly connected to one side of the laundry detergent distribution pipe, and each of the laundry detergent distribution branches is fixedly equipped with a discharge valve.
[0010] Preferably, the water supply pipe includes a main pipe disposed above the water shortage protection mechanism and branch pipes connected to the main pipe. A main control valve is fixedly installed at one end of the main pipe, and a branch control valve is fixedly installed on each branch pipe.
[0011] Preferably, the wall-mounted panel is L-shaped and has positioning holes at all four corners.
[0012] This wall-mounted, four-in-one laundry liquid dispenser has a simple structure and is easy to use. By opening the main control valve through the control box, clean water is added to the four branch pipes through the water inlet pipe. At this point, the transparent U-shaped tube is filled with clean water, and the floating component rises under its own buoyancy, which is detected by the photoelectric sensor. The photoelectric sensor then transmits an electrical signal to the control box, which starts the pump. The pump then draws laundry detergent from the first pipe and delivers it to the detergent distribution pipe through the second pipe, thus supplying detergent to the washing machine. By detecting water shortage and sending feedback to the control box, it prevents clothes from being scorched. Attached Figure Description
