Dispensing device and washing machine, liquid electrostatic sterilization method for washing machine

Abstract

This invention discloses a dispensing device, a washing machine, and a liquid electrostatic sterilization method for washing machines, relating to the field of home appliance technology. It solves the problem of requiring large amounts of detergent to wash clothes and the cumbersome and repetitive washing process. When the pressure in the pressure chamber exceeds the pressure of the spray device, the mixed liquid passes through the ionization atomization component, entering the spray device at high speed as a thin, elongated column of liquid, colliding to form charged droplets. These charged droplets are sprayed into the washing tub of the washing machine and come into contact with the wet clothes, initiating a discharge and completing the adsorption of impurities and sterilization process. It quickly removes and separates large amounts of stains, effectively reducing the washing process and killing a certain amount of bacteria and viruses that are difficult to kill at high temperatures.

Description

Technical Field

[0001] This invention relates to the field of home appliance technology, specifically to a dispensing device, a washing machine, and a liquid electrostatic sterilization method for washing machines. Background Technology

[0002] The principle behind drum washing machines for removing dust and dirt mainly relies on the variable speed rotation of the drum, which causes the clothes to repeatedly tumble and rub against the drum wall, thus removing the dirt and carrying it away with the water flow. Currently, the rise of ion energy has made washing and dust removal more convenient and thorough. For example, the earliest method used silver ions for direct adsorption, and later electrostatic ionization of water increased its stain-adsorption capacity.

[0058] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0059] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0060] like Figure 1 As shown, this invention provides a dispensing device, including a liquid storage box. The liquid storage box includes a water tank with a certain water storage space, and the water tank is connected to the water inlet branch pipe 2 and the detergent dispensing port 1 of the washing machine. When the water inlet branch pipe 2 adds water to the water tank, it adopts a continuous, small-volume supply method. A small amount of water is used to dilute the detergent. The water inlet branch pipe 2 begins adding water to the water tank when the washing machine water pump is turned on. It should be noted that when adding water to the washing machine, the water level in the washing tub should be maintained at a state where the clothes are wet and there is some standing water before stopping the water addition.

[0061] It also includes an electrostatic generator assembly, which comprises:

[0062] The ionization atomizing component 6 can be powered to form charged droplets from the liquid film and / or droplets on it and / or the fine stream flowing through it;

[0063] like Figure 2As shown, the ionization atomizing component 6 includes two staggered membranes A61 and B62, with pores on both membranes. The pore spacing of membrane A61 is greater than that of membrane B62, and the pores of the two membranes A61 are vertically staggered and not aligned at different angles. Membrane B62 has a denser mesh of small pores, which allows the liquid column to accumulate as much frictional charge as possible upon impact with the pore surface, while also ensuring that the liquid enters the injection channel at an angle after spraying.

[0064] The pores on membranes A61 and B62 are closed in the interlocking state.

[0065] When membranes A61 and B62 are wetted with a mixture and are under energized conditions, the mutual repulsion between membranes A61 and B62 due to the electromagnetic field can cause the pores to open.

[0066] Pressure chamber 7, which is provided with a jet outlet corresponding to the ionization atomization component, and the pressure of the pressure chamber can be adjusted;

[0067] The pressure chamber 7 is equipped with an adjustable pressure charging device 4, which is an air pump. The air pump outlet is connected to the pressure chamber 7. The air pump inlet is connected to the spraying device through an air pipe 5. The air pump 4 works to pressurize the pressure chamber 7. When the pressure is sufficient, the mixture can be separated and enter the spraying device.

[0068] The pressurization device 4 is connected to the spraying device through the air pipe 5 to adjust and / or clean the pressure inside the spraying device and remove any misaligned charged droplets.

[0069] The liquid supply device applies the liquid in the storage box to the ionization atomization component to form a liquid film and / or droplets and / or a fine stream flowing through the ionization atomization component;

[0070] The liquid supply device includes a liquid supply pipe 3 with a narrow opening on its outer wall, which removes foam from the liquid in the storage box and applies it to the ionization atomizing component 6. The narrow opening on the outer wall of the liquid supply pipe 3 is located in the pressure chamber 7. The liquid supply pipe 3 is connected to the outlet of the water box and is inserted into the pressure chamber 7, allowing the mixture in the water box to enter the pressure chamber 7 through the narrow opening on the outer wall of the liquid supply pipe 3. A very small amount of detergent seeps out with the water flow through the narrow opening on the outer wall of the liquid supply pipe 3 into the pressure chamber 7 below, removing most of the foam.

[0071] The spray device sprays charged droplets formed on the ionization atomization component into the washing tub of the washing machine.

[0072] The spraying device includes:

[0073] Cylinder 9;

[0074] The spray channel 8, which is built into the cylinder 9, has wall holes and is cone-shaped, and receives, gathers and transmits charged droplets downward to the sealing and isolation device 10.

[0075] A gap cavity is formed between the cylinder 9 and the injection channel 8, and the gap cavity is connected to the air pipe 5. The pressurization device 4 can adjust and / or clean the pressure in the gap cavity and remove any misaligned charged droplets.

[0076] The sealing and isolating device 10 insulates and isolates charged droplets from the spray into the washing tub of the washing machine.

[0077] The sealing and isolation device (10) includes an insulating chamber capable of collecting and temporarily storing charged droplets.

[0078] The insulating chambers include insulating chamber A101 and insulating chamber B102, which are interconnected and whose inlets and outlets can be freely opened and closed.

[0079] It should be noted that when the pressure in pressure chamber 7 is sufficient, the ionization atomization component 6 is energized. The mixture, after being separated by the ionization atomization component 6 under pressure, can enter the injection channel 8. A small portion of the charged droplets injected into the injection channel 8 enters the gap cavity through the holes in the upper wall of the injection channel 8, while the majority enters the sealing and isolation device 10. The charged droplets in the gap cavity can be siphoned back to pressure chamber 7 through the injection channel and pumped by the air pipe 5.

[0080] Specifically, after the user puts in large items of clothing and starts the washing function, the pressurizing device 4 pressurizes the pressure chamber 7 and discharges the air pressure around the spray channel through the air pipe 5, creating a large pressure difference between the upper and lower parts of the ionization atomizing component 6. When the pressure in the pressure chamber 7 is greater than the pressure in the external gap cavity of the spray channel 8, the mixed liquid passes through the ionization atomizing component 6 and enters the spray device at high speed as a thin columnar liquid, colliding with the air to form charged droplets.

[0081] The ionization atomizing component 6 is located between the pressure chamber 7 and the spraying device, and is closedly connected to the spraying device. The closed end of the ionization atomizing component 6 is connected to the power supply unit of the washing machine.

[0082] It should be noted that the charged droplets formed by the impact of air in the spray channel converge in the insulating chamber A101. When the set capacity or time is reached, the insulating chambers A101 and B102 open and close intermittently to spray the charged droplets into the washing tub of the washing machine.

[0083] The present invention also provides a washing machine, including a washing tub, a detergent dispensing pump, a water inlet pipe, and a dispensing device.

[0084] A small amount of water is added to the washing machine to wet the clothes, but water accumulates in the washing tub. At this time, the motor is turned on slowly to disperse and tumble the clothes. The dispensing device then begins to spray charged water into the washing tub in small amounts multiple times. Upon contact with the clothes, the water begins to discharge, thus quickly adsorbing stains and sterilizing them.

[0085] like Figure 3As shown, the present invention also provides a liquid electrostatic sterilization method for washing machines, which utilizes charged droplets formed by a dispensing device to perform electrostatic sterilization on clothes in the washing tub.

[0086] include:

[0087] Step 1: The washing machine starts working, the water pump turns on, and a small amount of water is added to the washing tub.

[0088] Step 2: The detergent dispensing pump identifies whether a detergent dispensing command has been received;

[0089] Step 3: When the instruction is recognized as yes, detergent and a small amount of water flow into the water box through detergent dispensing port 1 and water inlet branch pipe 2 and mix; the mixture enters the pressure chamber 7 through the narrow opening on the outer wall of liquid supply pipe 3, and most of the foam is removed by the narrow opening;

[0090] When the command is not detected, the pressurizing device 4 is activated to pressurize the pressure chamber 7. While the pressurizing device 4 is working, the air pressure in the gap chamber is reduced through the air pipe 5.

[0091] Step 4: Activate the pressurizing device 4 to pressurize the pressure chamber 7. While the pressurizing device 4 is working, it reduces the air pressure in the gap chamber through the air pipe 5.

[0092] Step 5: When the pressure in the pressure chamber 7 is satisfied, the ionization atomization component 6 is energized, causing the mixture on the surface to be affected by the electromagnetic field, resulting in mutual repulsion between the internal components and changing the pores from an interlocked state to an open state.

[0093] If the pressure in pressure chamber 7 is not sufficient, a command is sent back until the pressure is sufficient, at which point the ionization atomization component 6 is energized.

[0094] Step 6: The mixture is subjected to pressure in the pressure chamber 7 and passes through the ionization atomization component 6 to form a charged, slender columnar liquid. It then enters the injection channel at high speed and collides with the air to form charged droplets.

[0095] Step 7: Charged droplets converge in the insulating chamber A101;

[0096] Step 8: When the set capacity or time is reached, the insulating chamber A101 and the insulating chamber B102 are opened and closed alternately to spray charged droplets into the washing tub of the washing machine.

[0097] Step 9: Repeated spraying causes charged droplets to come into contact with the slowly rotating wet clothing, initiating a discharge and completing the process of adsorbing impurities and sterilizing the clothing.

[0098] Step 10: Repeat the process of opening and closing the pressurizing device 4 to pressurize the pressure chamber 7. While the pressurizing device 4 is working, the air pressure in the gap chamber is reduced through the air pipe 5 to open the channel locking piece B and spray the charged droplets into the washing tub of the washing machine.

[0099] When the ionization atomizing component 6 is energized, the membranes A61 and B62 repel each other under the influence of the electromagnetic field, causing the pores to change from an interlocked state to an open state.

[0100] Step 11: After the set number of charged droplet injections is reached, the water inlet branch pipe is flushed and the water is collected back into the washing machine tub, and the washing machine enters the normal water filling and washing operation.

[0101] Charged droplets formed in the injection channel enter the gap cavity through the hole in the injection pipe wall. Charged droplets that remain in the gap cavity and on the surface of the sealing isolation device 10 are siphoned back to the pressure chamber 7 through the injection channel 8 and / or the air pipe 5.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0103] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
