Description

a washing machine

technical field

The invention relates to a washing machine, in particular to a wave wheel washing machine and a drum washing machine.

Background technique

The washing machine uses washing powder or laundry detergent to wash clothes, and the method of using the washing powder should be "dissolve the washing powder in the water first, and then soak the clothes in" (refer to the "White Cat" brand washing powder packaging bag The method of use printed on it); the clothes mentioned here refer to "dry" clothes. Experts in the washing industry know that from the principle of physical permeability, the washing efficiency of "dry" clothes immersed in detergent solution is the highest. Because the washing powder solution can easily penetrate into the inside of the clothes fibers and expel air molecules, the detergent ingredients can easily wet the stains and peel off the stains; and if the clothes are pre-soaked with water, the detergent ingredients need to pass through a high concentration difference. The diffusion of the solution and the forced convection (stirring) of the solution can enter the interior of the clothing fibers and then wet the stains therein. Therefore, stronger washing power is required, a higher concentration of washing powder, or a higher temperature is required. If other conditions are the same, washing "wet" clothes consumes 1-3 times more detergent than "dry" clothes.

Soaking "dry" laundry in a detergent solution can also be done in existing washing machines. Consumers can first take out the laundry to be washed from the inner tub, then put washing powder into the inner tub and add water, start the washing machine to fully dissolve the washing powder, and then put "dry" clothes into the inner tub for formal washing. But consumers generally don't do this, because they don't know that doing so can improve the washing efficiency. In addition, for fully automatic washing machines, it is also time-consuming and troublesome, so it becomes not "automatic".

In fact, the design of the existing washing machine does not take into account that the washing powder needs to be dissolved separately. The washing procedure includes: water intake (adding washing powder or laundry detergent), washing, rinsing, dehydration, etc., and in the water intake stage, Water, washing powder and clothes are added into the inner tub of the washing machine until the water level reaches the set water level, and the clothes are soaked before being washed. Therefore, the design of the existing washing machine does not design the washing powder to be dissolved in a separate space. Due to the limitation of space, the dissolution of the washing powder and the washing of the clothes are designed to be carried out in the inner tub; perhaps if a separate space is set in the washing machine It is used to dissolve washing powder to ensure that the clothes can be immersed in the washing powder solution in a "dry" state. The washing machine will become very bulky and the cost will be high.

Therefore, the washing machine in the prior art does not meet the requirements in the washing powder usage method. As a result, the washing efficiency of the natural washing machine is greatly reduced, and consumers waste time and washing powder.

In the existing washing machine, there is a washing powder box in the water supply flow channel, so that the incoming water flows through the washing powder box to dissolve the washing powder. On the one hand, the washing powder is not easy to dissolve, and on the other hand, even if it is dissolved, it is not easy to dissolve the washing powder. Evenly distributed in the passing water, so not much significance. There are also people who add washing liquid to the washing powder box. Although the washing liquid does not have the problem of dissolving, it has the problem of being difficult to mix, so it cannot completely solve the problem.

The washing machine in the prior art will be further described below with common pulsator washing machines and drum washing machines.

A traditional pulsator washing machine is shown in Figure 1. The washing machine mainly consists of a water supply mechanism, a drainage mechanism located at the bottom of the outer tub, a driving mechanism, a control system, an inner tub, and an outer tub. Specifically, the outer tub 17 encases the inner tub 18 which is freely rotatable, and is suspended from the machine body 1 of the washing machine by a suspension rod 19 . The motor 21 rotates and drives the inner tub 18 and the pulsator 25 coaxial with the inner tub 18 through the reduction mechanism 22 . The upper part of the back of the body 1 is provided with a water supply port 8, the water supply port 8 is connected with the water tap through the hose 8a, the solenoid valve 23 is opened, and the water is supplied to the inner bucket 18 through the water inlet 27, and the water level of the inner bucket 18 is connected to the outer bucket 18 through the through hole 18e. The water level in the bucket 17 remains consistent. The drain valve 25 drains the washing water in the outer tub 17 . Also have the water feeder 9 that comprises washing powder box 11 to be set between water inlet 27 and electromagnetic valve 23, allow water to flow through washing powder box 11.

This washing machine, clothing is put into inner barrel 18 and adds washing powder again, water supply, until water level reaches the water level of setting washing, motor starts driving inner barrel and impeller to rotate, and washes. Here, the clothes are soaked in water first, and the washing powder has not yet been dissolved, so the washing efficiency is low.

A traditional drum washing machine is shown in Figure 2. The body 1 of the drum washing machine is provided with: an outer tub 17 supported by the shock absorbing mechanism 2; and a rotatable inner tub 18 (rotary drum) supported in the outer tub 17 . The angle between the axis c of the inner barrel 18 and the horizontal line H is e. The inner tub 18 is driven to rotate by the driving motor 5 fixed on the bottom surface of the outer tub 17 . The front side of the body 1 is provided with a door 6 that can be opened and closed freely. After the door 6 is opened, it can be dropped into the inner tub 18 through the front side opening 17a on the outer tub 17 and the front side opening portion 18a on the inner tub 18. Remove laundry.

In addition, a solenoid valve 23 for controlling water intake is arranged in the upper space in the body 1, and a water supply port 8 is arranged on the upper back of the body 1, and the water supply port 8 is connected with a water tap through a hose 8a. The front of the electromagnetic valve 23 is provided with a water supply device 9, and the inside of the water supply device 9 is provided with a washing powder box 11 that can be pulled out freely, which acts as a washing powder input device. , the water level of the inner barrel 18 is kept consistent with the outer barrel 17 through the through hole 18e.

In addition, the bottom rear of the outer barrel 17 is provided with a drain port 12, and the drain port is connected with a drain valve 13. When the drain valve 13 was opened, the water in the outer tub 17 could be discharged outside the machine by the drain pipe 14 .

This washing machine is the same as the pulsator washing machine, and clothing is put into inner bucket 18, adds washing powder, water supply, until water level reaches the water level of setting washing, and motor starts to drive inner bucket to rotate, and washes.

Contents of the invention

The purpose of the present invention is to provide a washing machine that meets the requirements for the use of washing powder. The problem to be solved is that the clothes are pre-placed in the inner tub, and the "dry" clothes can also be soaked in the detergent solution instead of water. Furthermore, before the washing program starts, the washing powder dissolves in a relatively independent space (the gap between the inner tub and the outer tub), and the clothes are in another relatively independent space (inner tub); Completed or nearly completed, the two spaces form a water flow channel, and the "dry" laundry is immersed in the detergent solution.

A kind of washing machine provided by the present invention, that is, the commonly used pulsator washing machine and drum washing machine, is improved on the control system and structure, so that the dissolving of washing powder and the washing of clothes can be carried out in different spaces.

In the washing machine of the present invention, the impeller washing machine is improved, which can be improved from two aspects. 1. In the existing washing machine, washing powder and water are directly added into the inner tub of the washing machine. in the space between the barrels. That is, the tap water from the tap is connected to the washing powder box through a solenoid valve, and the bottom of the washing powder box is connected with a water inlet pipe leading to the gap between the inner tub and the outer tub of the washing machine. Washing powder is added from the washing powder box, and the water coming in from the tap washes away the washing powder, and flows into the gap between the inner tub and the outer tub of the washing machine from the water inlet. Above-mentioned washing powder box also can be the washing powder box of existing washing machine. 2. In terms of the control system, the inner barrel in the water inlet program does not rotate, but now, after the water inlet solenoid valve is opened, the motor is energized to drive the inner barrel to rotate (while the pulsator does not rotate). That is, through the deceleration mechanism, the inner tub is driven to start rotating, and the washing powder is dissolved by the agitation of the inner tub or the appendage fixedly connected with the inner tub.

Another washing machine described in the present invention is improved with a drum washing machine. It is also improved from two aspects. 1. The original washing powder and water are directly added to the inner tub of the washing machine, but now they are added to the gap between the inner tub and the outer tub. That is, the tap water from the tap is connected to the washing powder box through a solenoid valve, and the bottom of the washing powder box is connected with a water inlet pipe leading to the gap between the inner tub and the outer tub of the washing machine. Washing powder is added from the washing powder box, and the water coming in from the tap washes away the washing powder, and flows into the gap between the inner tub and the outer tub of the washing machine from the water inlet. 2. In terms of the control system, the inner barrel in the water inlet program does not rotate, but now it is changed to open the water inlet solenoid valve, and then the motor is energized to drive the inner barrel to rotate, using the stirring effect of the inner barrel or the appendages that are fixedly connected with the inner barrel Promote the dissolution of washing powder.

The invention can save more than 30-70% of washing powder, greatly reduce the concentration of washing powder, reduce washing strength, protect clothes and protect the environment.
