Description

Technical Field

[0001] This utility model relates to the field of kitchen equipment technology, specifically to a pulsator cleaning machine and an integrated sink. Background Technology

[0002] The sink-type washer inside the integrated sink is used to wash dishes, fruits and vegetables, etc.

[0003] To improve cleaning results, people have applied the rotating impeller cleaning solution to sink-type dishwashers. For example, the Chinese patent application number CN201820891413.7, "A Sink Dishwasher", places the impeller assembly at the bottom of the dish rack to rotate and repeatedly rise and fall, enhancing the turbulence of the water and making the cleaning more efficient and faster.

[0004] After cleaning, the clean water in the outer tub is discharged through the drain outlet under gravity after the drain valve is opened normally. However, because the filter screen is small, the outflow area is small and the drainage speed is slow. Utility Model Content

[0005] The first technical problem to be solved by this utility model is to provide a pulsator cleaning machine that can accelerate the drainage speed, in light of the current state of the technology.

[0006] The second technical problem to be solved by this utility model is to provide an integrated water tank that uses the above-mentioned impeller cleaning machine.

[0007] The technical solution adopted by this utility model to solve the first technical problem mentioned above is as follows: a pulsator cleaning machine, comprising an outer tub, an inner tub disposed within the outer tub, a pulsator disk disposed at the bottom of the inner cavity of the inner tub, and a driving component for driving the pulsator disk to rotate, wherein the bottom of the outer tub has a drain outlet, characterized in that: it further comprises...

[0008] A wastewater tank has a water inlet and a vent, and the drain outlet is connected to the water inlet via a drain pipe; and

[0009] An air pump, the air intake end of which is connected to the air vent via an air delivery pipe.

[0010] To facilitate the discharge of sewage from the sewage tank, the bottom of the sewage tank has a water outlet.

[0011] To avoid interference between the sewage entering and exiting the sewage tank, the air pump's blowing end is connected to the air vent through an air supply pipe. A first valve for controlling the opening and closing of the drain pipe is installed on the drain pipe. A water outlet is connected to the water outlet, and a second valve for controlling the opening and closing of the water outlet is installed on the water outlet.

[0012] The impeller cleaning machine described above has at least two states:

[0013] In the first state, the air pump is in the intake state, the drain pipe is in the connected state, and the water outlet pipe is in the disconnected state.

[0014] In the second state, the air pump is in the blowing state, the drain pipe is in the disconnected state, and the water outlet pipe is in the connected state.

[0015] To facilitate control of the drain pipe's opening and closing, the first valve is a solenoid valve. In the first state, the first valve is open, and in the second state, the first valve is closed.

[0016] In order to accurately control the flow of the outlet pipe while reducing the cost of the second valve, the second valve is a one-way valve that only allows fluid to be delivered from the inlet end to the outlet end of the outlet pipe.

[0017] To achieve unidirectional fluid transport, the second valve includes:

[0018] Valve cylinder, connected to the outlet end of the water outlet pipe;

[0019] A fixed base is provided at the bottom end of the valve cylinder;

[0020] The piston is movably housed within the valve cylinder; and

[0021] An elastic element acts between the fixed seat and the piston;

[0022] In the first state, the piston blocks the port at the top of the valve cylinder under the elastic force of the elastic element;

[0023] In the second state, the piston releases the seal on the top port of the valve cylinder under the pressure inside the sewage tank.

[0024] To facilitate the installation of the elastic element, a first protrusion and a second protrusion are respectively provided on the opposite surfaces of the fixed seat and the piston. The elastic element is a compression spring, and the two ends of the compression spring are respectively sleeved on the outer periphery of the first protrusion and the second protrusion, and respectively abut against the opposite surfaces of the fixed seat and the piston.

[0025] To simplify the structure, the air pump's intake and exhaust ends share the same port.

[0026] In order to facilitate the collection of sewage in the sewage tank to the outlet for discharge, the bottom surface inside the sewage tank gradually rises from the periphery of the outlet to the outer periphery of the sewage tank.

[0027] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: an integrated water tank using the above-mentioned impeller cleaning machine.

[0028] Compared with the prior art, the advantages of this utility model are: by adding a sewage tank and an air pump, when the outer bucket needs to drain, the air pump is started to rotate forward and draws air from the sewage tank through the air supply pipe. Under the action of negative pressure in the sewage tank, the sewage in the outer bucket quickly enters the sewage tank through the drain pipe, which can speed up the drainage speed.

For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0034] like Figures 1 to 3 The image shows a preferred embodiment of the integrated water tank incorporating a pulsator cleaning machine according to this utility model. The pulsator cleaning machine includes an outer tank 1, an inner tank 2, a pulsator disc 3, a drive unit 4, a wastewater tank 5, an air pump 6, a first valve 7, and a second valve 8.

[0035] The outer tub 1 has a water inlet 11 on its side wall and a drain outlet 12 on its bottom wall, which is covered with a filter screen.

[0036] The inner tub 2 is circumferentially confined within the outer tub 1.

[0037] The impeller 3 is rotatably mounted at the bottom of the inner cavity of the inner tub 2.

[0038] The driving component 4 is a motor, which is installed at the bottom of the outer tub 1. The power output shaft of the motor passes through the bottom wall of the outer tub 1 and the inner tub 2 in sequence and is connected to the impeller 3 to drive the impeller 3 to rotate.

[0039] The top wall of the sewage tank 5 has spaced water inlet holes 51 and vent holes 52. The drain outlet 12 is connected to the water inlet holes 51 through the drain pipe 121. The bottom wall of the sewage tank 5 has a water outlet hole 53, and a water outlet pipe 531 is connected to the water outlet hole 53. In addition, the bottom surface inside the sewage tank 5 gradually rises from the periphery of the water outlet hole 53 to the outer periphery of the sewage tank 5, which facilitates the sewage in the sewage tank 5 to collect and be discharged through the water outlet hole 53, thus solving the problem that normal planar drainage is prone to surface adsorption of stains.

[0040] The air pump 6 has an intake end and an exhaust end, and the intake end and exhaust end of the air pump 6 share the same port, which is connected to the vent 52 through the air supply pipe 61.

[0041] The first valve 7 is installed on the drain pipe 121 and is used to control the opening and closing of the drain pipe 121. In this embodiment, the first valve 7 is a solenoid valve.

[0042] The second valve 8 is installed on the outlet pipe 531 and is used to control the opening and closing of the outlet pipe 531. In this embodiment, the second valve 8 is a one-way valve that only allows fluid to be transported from the inlet end to the outlet end of the outlet pipe 531. The one-way valve includes a valve cylinder 81, a fixed seat 82, a piston 83, and an elastic element 84. Specifically, the valve cylinder 81 is connected to the outlet end of the outlet pipe 531; the fixed seat 82 is located at the bottom end of the valve cylinder 81; the piston 83 is movably housed in the valve cylinder 81, and a first protrusion 821 and a second protrusion 831 are respectively protruded on the opposite surfaces of the fixed seat 82 and the piston 83; the elastic element 84 is a compression spring, and the two ends of the compression spring are respectively sleeved on the outer periphery of the first protrusion 821 and the second protrusion 831, and respectively abut against the opposite surfaces of the fixed seat 82 and the piston 83, so that the piston 83 always has an upward tendency.

[0043] The aforementioned impeller cleaning machine has at least two states:

[0044] In the first state, the air pump 6 rotates forward and is in the suction state; the first valve 7 is opened to make the drain pipe 121 connected; the piston 83, under the elastic force of the elastic element 84, blocks the port at the top of the valve cylinder 81 to make the water outlet pipe 531 disconnected.

[0045] In the second state, the air pump 6 reverses and is in the blowing state; the first valve 7 is closed so that the drain pipe 121 is in the disconnected state; the piston 83 releases the blockage on the top port of the valve cylinder 81 under the action of the pressure in the sewage tank 5 so that the outlet pipe 531 is in the connected state.

[0046] The working principle of this embodiment is as follows:

[0047] (1) When the outer tub 1 needs to drain, open the first valve 7 and start the air pump 6 to rotate in the forward direction. Air is drawn from the sewage tank 5 through the air pipe 61. Under the negative pressure in the sewage tank 5, the sewage in the outer tub 1 quickly enters the sewage tank 5 through the drain pipe 121.

[0048] (2) When the sewage tank 5 needs to drain water, close the first valve 7 and start the air pump 6 in reverse. Blow air into the sewage tank 5 through the air pipe 61. Under the action of positive pressure in the sewage tank 5, the piston 83 moves down to release the blockage on the top port of the valve cylinder 81. The sewage in the sewage tank 5 is discharged out through the outlet pipe 531 (usually to the floor drain).
