Detailed ways

The specific embodiments of the present invention will be described below with reference to the accompanying drawings. It should be noted that the following embodiments do not limit the technical scope of the present invention.

The washing machine of the high-level lifting directional spraying system according to the present invention mainly consists of the washing machine and the high-level lifting directional spraying system.

Said washing machine is any type of washing machine in the prior art, as long as such a system is needed, the device of the present invention can be used.

The high-level lifting directional spraying system of the present invention is mainly composed of three parts, namely high-level lifting, directional spraying and atomization device.

The high-level lifting described in the present invention adopts the lifting pump 14, and the liquid to be atomized is lifted into the directional spraying system 18 by connecting the outlet water pipe 15 and the lifting water pipe 13 thereon.

The ultrasonic atomization device of the present invention includes a piezoelectric transducer 1, a bracket 2 located below the piezoelectric transducer, which is used to fix the transducer 1, wherein an axial lead hole 8 is provided; A cylindrical coupling part 3 is arranged above the transducer, and an annular rib 9 is arranged inside, and the connection between the lower part of the annular rib 9 and the outside of the bracket 2 is a screw connection. The transducer 1 is hermetically installed between the annular rib and the bracket.

The amplitude-changing diaphragm 4 is arranged on the top of the coupling part, which is fixed by the pressure film ring 6 and the cylindrical coupling part 3, and the pressure film ring 6 and the cylindrical coupling part 3 are also fixed by screw connection.

The sealed space formed between the cylindrical coupling part 3 , the transducer 1 and the amplitude-changing diaphragm 4 is filled with a coupling liquid 5 , which is a non-corrosive and non-precipitating solution, preferably pure water.

There is a container outside the atomizing device, and the bottom of the container is airtightly connected with the bracket 2 so as to form a container for holding the lifted liquid.

In order to prevent problems caused by the liquid that is lifted more than the liquid that is atomized, a liquid level gauge 16 can be set in the container to control the pump 14 through an electrical signal, or an overflow port 17 can be set on the side wall thereof, so that the Excess liquid flows out along the designated position.

It is one of the characteristics of the present invention that the bracket 2 and the cylindrical coupling part 3, and between the cylindrical coupling part 3 and the pressure film ring 6 are arranged to be threadedly connected, because in this way, it can be easily disassembled for cleaning , and can make the coupling liquid 5 form a long-term sealed and leak-free environment.

Although the improvement of the ultrasonic generator described in the washing machine technology also adopts the coupling mode in principle, such as described in the reference document quoted in the background technology above, they still have serious defects:

One is that when the piezoelectric transducer 1 is damaged, the entire atomization system must be replaced, but in the present invention only the piezoelectric transducer 1 needs to be replaced.

Second, even if the piezoelectric transducer 1 is not damaged, if the coupling fluid 5 is missing due to long-term use, the atomization system will also be able to work normally.

Third, if only the amplitude-changing diaphragm 4 is damaged, according to the method of the present invention, the required parts can be replaced flexibly and cheaply, and the method of the present invention has more practical significance in the process of repair and maintenance of the washing machine.

In the present invention, considering the defects of the prior art, a directional spray device is specially provided, and the device includes a cylindrical body, and a fan 11 is arranged in the cylindrical body. The far end of the liquid is provided with a fan motor 10, so that the damage of the atomized liquid droplets to the fan motor 10 and the fan 11 is avoided.

An air inlet 12 is set at the end of the cylindrical body behind the motor, so that the fan can obtain enough air to blow the atomized liquid droplets, and an atomized liquid directional outlet 7 is set at the front end of the cylindrical body, and the outlet faces the specified direction. As an option, the direction of the atomized liquid directional outlet 7 can be adjusted, and the simplest way is to adopt a structure similar to a "snake skin water pipe", so that users can adjust the direction of the outlet 7 even more.

In the accompanying drawings described in the present invention, the corresponding part numbers and legends are as follows: piezoelectric transducer 1, bracket 2, cylindrical coupling part 3, amplitude-changing diaphragm 4, coupling liquid 5, pressure film ring 6 , Atomized liquid directional outlet 7, lead hole 8, annular edge 9, fan motor 10, fan 11, air inlet hole 12, lifting water pipe 13, lifting pump 14, leading water pipe 15, liquid level gauge 16, overflow port 17, Directional spray system 18 .

In the directional spraying system 18 of the present invention, due to the coupling method adopted, the atomizing device does not directly contact the cleaning water, thereby preventing dirt from adhering and solidifying on the vibrating surface of the mist generating oscillator 14 .

At the same time, due to the structural design of the same speed, even if it is damaged again, it can be easily replaced as mentioned above to ensure long-term stable operation.

The washing machine of the high-level lifting directional spraying system of the present invention, in actual use, as shown in Figures 1 and 2, has a directional spraying system on the upper part of the body of the washing machine or at an appropriate position, and the structure of the directional spraying system mist is shown in Figure 2 shown in .

During the washing process, first put clothes into the inner bucket, and then start the operation; after the operation starts, first open the water inlet valve to add water at the specified water level, and then make the washing machine motor start to rotate, and the pulsator rotates accordingly. Drain and rinse again.

After rinsing, the dehydration process is performed. During the dehydration process, first open the drain valve to drain the water in the inner tub, and then make the inner tub separate the water from the clothes through the centrifugal force exerted on the clothes.

When necessary, put in cleaning agent in advance when doing laundry, then put in clothes and add water, water will accumulate at the bottom of the washing machine, and the lift pump will be driven to lift the water into the container where the directional spray system 18 is located, and the piezoelectric transducer will start to work. The vibration will propagate in the enclosed coupling liquid, causing the amplitude-changing diaphragm 4 to vibrate, so that the washing liquid is atomized, and the atomized liquid droplets are blown to the designated position by the wind force of the fan.

Atomized liquid droplets containing cleaning agent form the so-called high-concentration washing liquid, and they will adhere to various parts of the clothes. By leaving it in this state for an appropriate time, the high-concentration cleaning agent solution will make the clothes adhere to Wait for the dirt on your clothes to break down chemically before performing the normal wash-to-spin cycle.
