Description

Technical Field

[0001] The utility model belongs to the technical field of washing machine accessories, and particularly relates to a multifunctional automatic dosing device. Background Art

[0002] Existing washing machines often have an automatic dosing device, which is used to dose different types of detergents into the drum of the washing machine. The existing automatic dosing device often pumps detergents through a piston pump. When the piston pump works, it pumps the detergents from the dispenser box to the water circuit board. The water circuit board is often only connected to a single water inlet channel, and the dispenser box is installed in the water storage tank. Since the automatic dosing device often only has a single water inlet channel, clean water and detergents are easily mixed and contaminated, resulting in the clean water entering the drum of the washing machine not being pure enough and the washing effect being poor. At the same time, there is no anti-backflow structure between the water inlet channel and the water circuit board. When negative pressure is generated in the water inlet channel, liquid often flows back, contaminating the water source. Therefore, it is necessary to design a multifunctional automatic dosing device to overcome the above difficulties. Summary of the Invention

[0003] Aiming at the problems existing in the prior art, the utility model designs a multifunctional automatic dosing device. The utility model sets a separate second water circuit in the water storage tank for water supply, and the first water circuit and the second water circuit do not interfere with each other; an anti-backflow component is arranged on the first water circuit, and the anti-backflow effect is good and reliable. The second water circuit is connected to the first cavity, and the air pressure is balanced through the gap on the partition plate between the first cavity and the second cavity, avoiding backflow in the second water circuit.

[0004] The invention object of the utility model is realized through the following technical solutions: a multifunctional automatic dosing device, including a water storage tank, a water circuit board is arranged above the water storage tank, and a first water circuit communicated with each other is arranged on the water circuit board. An anti-backflow component is arranged between the first water circuit and the water circuit board; a first cavity and a second cavity are arranged in the water storage tank, and a second water circuit is also arranged outside the water storage tank; a dispenser box component is arranged in the second cavity and is plugged and connected with the second cavity, and the second water circuit is communicated with the first cavity; a partition plate is arranged between the first cavity and the second cavity, and a gap is left between the partition plate and the water circuit board.

[0005] Preferably, a liquid pumping component for pumping liquid is arranged below the water circuit board; the liquid pumping component includes a piston pump, and the piston pump is communicated with the water circuit board; a detergent inlet is arranged on the water circuit board, and the detergent inlet is connected to the dispenser box component; when the piston pump works, it pumps the detergents in the dispenser box component along the detergent inlet to the water circuit board.

[0006] When the piston pump works, the detergents in the dispenser box component will be pumped to the detergent inlet, then the detergents enter the inside of the piston pump, and then are pumped from the piston pump to the water circuit board.

[0007] Preferably, a guiding flow channel is provided on the water circuit board. One end of the guiding flow channel is connected to the detergent inlet, and a first through hole is provided at the other end of the guiding flow channel. A second through hole is also provided on the water circuit board. The first through hole is connected to the inlet of the piston pump, and the second through hole is connected to the outlet of the piston pump. A common water circuit adjacent to the guiding flow channel is further provided on the water circuit board. The second through hole is provided on the common water circuit. When the piston pump works, the detergent is drawn from the guiding flow channel to the common water circuit. A connecting pipe is provided between the detergent inlet and the dispenser box assembly to connect the two.

[0008] When the piston pump works, the detergent is drawn from the dispenser box assembly to the detergent inlet along the connecting pipe, and then the detergent flows along the guiding flow channel. When the detergent flows into the first through hole, it is drawn into the inlet of the piston pump, and then the detergent enters the second through hole from the outlet of the piston pump. The second through hole is provided on the common water circuit, so that the detergent can be drawn from the dispenser box assembly to the common water circuit of the water circuit board.

[0009] Preferably, a detergent inlet is provided on the water circuit board, and the detergent inlet extends towards the first cavity. The first cavity and the partition plate are integrally formed. A liquid holding scale surface is provided on the upper end surface of the partition plate, and the vertical distance between the liquid holding scale surface and the detergent inlet is greater than 20 mm. A first outlet is provided at the bottom of the first cavity, and a second outlet is provided at the bottom of the water storage tank. The first outlet and the second outlet are connected by a first pipeline. The second outlet extends towards the inside of the water storage tank, and a ventilation port is provided at the end of the second outlet facing the water storage tank.

[0010] Generally, the first cavity is in a closed state, and the clear water directly enters the water circuit board from the first water circuit. When it is necessary to provide clear water to the water storage tank alone, the second water circuit is opened. Since there is a partition plate between the first cavity and the second cavity, after the second water circuit is opened, the clear water directly enters the second outlet along the first pipeline from the first outlet. Due to the setting of the partition plate, the clear water in the first cavity will not flow into the second cavity. The maximum water storage capacity of the first cavity is often determined by the height of the partition plate. The liquid holding scale surface on the upper end surface of the partition plate is flush with the maximum water storage liquid level in the first cavity. The vertical distance between the liquid holding scale surface and the detergent inlet is greater than 20 mm, so as to ensure that the gap between the partition plate and the water circuit board is sufficient to balance the air pressure, so that the pressures of the first cavity and the second cavity are the same, and prevent the clear water from flowing back from the first cavity to the second water circuit.

[0011] Preferably, the anti-backflow assembly includes an inlet channel and an outlet channel, and the inlet channel and the outlet channel are coaxially arranged. A partition chamber is provided between the inlet channel and the outlet channel, and the partition chamber extends along the axial directions of the inlet channel and the outlet channel.

[0012] Preferably, the water inlet channel and the water outlet channel are in a flared shape, and the initial opening of the water inlet channel is smaller than that of the water outlet channel; the axial spacing of the separation chamber is greater than 20 mm.

[0013] Preferably, a first cover body for covering the water circuit board is provided above the water circuit board; a plurality of shower nozzles are provided at the open end of the water circuit board close to the water storage tank, and a guiding column body coaxial with the shower nozzles is provided on the lower end surface of the water circuit board; two first retaining ribs and a second retaining rib arranged side by side are further provided on the lower end surface of the water circuit board, the first retaining rib is arranged close to the shower nozzle, and the second retaining rib is adjacent to the first retaining rib; a plurality of limiting and guiding openings for draining water are provided on the upper end surface of the water circuit board, and the limiting and guiding openings are adjacent to the shower nozzles.

[0014] The arrangement of the shower nozzles facilitates drainage. By providing the guiding column body on the lower end surface of the shower nozzles, the liquid is guided, preventing the liquid from flowing randomly on the lower end surface of the water circuit board. Through the first retaining rib and the second retaining rib, the liquid is limited, preventing the liquid from flowing from the shower nozzles to the lower end surface of the water circuit board. By providing the limiting and guiding openings, the flow direction of the liquid on the upper end surface of the water circuit board is limited, preventing the liquid from flowing randomly on the upper end surface of the water circuit board.

[0015] Preferably, the dispenser box assembly includes a lower box body and a second cover body, and the lower box body and the second cover body are connected by snap fit; a plurality of first type placement cavities for placing detergents are provided in the lower box body, and the second cover body and the first type placement cavities are arranged in an upper and lower covering manner. By providing a plurality of first type placement cavities in the lower box body, different types of detergents can be placed separately in each of the first type placement cavities.

[0016] Preferably, a second type placement cavity for placing washing powder is further provided in the lower box body; a separation groove is provided between the first type placement cavity and the second type placement cavity; a strip-shaped retaining strip is provided at the edge of the cover body of the second cover body, and the inclined surface of the strip-shaped retaining strip faces the second type placement cavity.

[0017] By providing the second type placement cavity, it is convenient to place solid washing powder in the second type placement cavity, and a gap for draining water is provided at the bottom of the second type placement cavity. When the user puts a large amount of washing powder, the gap for draining water in the second type placement cavity will be blocked; the separation groove is adjacent to the side wall of the second type placement cavity, and the washing powder cannot enter the interior of the separation groove before being mixed with clean water; when the second type placement cavity is filled with water and the water overflows the strip-shaped retaining strip, the water will directly flow into the separation groove, and part of the washing powder will be carried away when the clean water flows through, and then the remaining washing powder will be washed away in sequence. The inclined surface of the strip-shaped retaining strip faces the second type placement cavity, thus preventing the liquid in the second type placement cavity from splashing onto the upper end surface of the second cover body, and the liquid will flow back into the second type placement cavity along the inclined surface of the strip-shaped retaining strip.

[0018] Preferably, a plurality of strip-shaped guiding ribs are provided on the upper end surface of the second cover body, and the second cover body is located on the lower end surface of the water channel plate when the dispenser box assembly is installed in the water storage tank; strip-shaped protrusions inserted between the strip-shaped guiding ribs are provided on the water channel plate.

[0019] Through the mutual cooperation of the strip-shaped guiding ribs and the strip-shaped protrusions, it is convenient to install the dispenser box assembly into the water storage tank, and the insertion and extraction of the dispenser box assembly are more convenient and fast.

[0020] Compared with the prior art, the utility model has the following beneficial effects: 1. Water is supplied to the water channel plate through the first water channel, and the first cavity is separately supplied with water through the second water channel, so that the first water channel and the second water channel do not interfere with each other, avoiding the mixing and pollution of clean water and detergent. 2. An anti-backflow assembly is arranged between the first water channel and the water channel plate, thereby avoiding the liquid on the water channel plate from flowing back and preventing the liquid on the water channel plate from polluting the water source in the first water channel. 3. Partition plates are arranged in the first cavity and the second cavity, and the air pressure is balanced through the gap between the partition plates and the water channel plate, avoiding the reverse flow of the second water channel.
