Description

The present invention belongs to the field of cleaning, and in particular to cleaning equipment and methods of dispensing cleaning water.

Generally, a conventional fully automatic pulsator washing machine consists of an inner tub, an outer tub, a damper and a power system. During washing and dehydration, the rotation of the inner tub with respect to the outer tub creates an action between the clothes and the washing water, thereby achieving the purpose of washing or dehydrating the clothes. The outer tub is mounted outside the inner tub to support the inner tub. Also, the outer tank becomes a water tank. Drainage holes are uniformly arranged on the side wall of the inner tank, and the inner tank and the outer tank are communicated with each other. During the washing process, clothes are put into the inner tub and the water levels in the two tubs are the same, but the outer tub does not come into contact with the clothes. Since the outer tub of a conventional washing machine is larger in volume than the inner tub, a large amount of washing water remains between the inner and outer tubs, and the washing liquid between these tubs cannot be fully utilized. As a result, the amount of water used during washing increases, the concentration of the washing liquid during washing decreases, and the volume of the washing machine as a whole becomes excessively large. In addition, after a certain period of time has passed since use, dirt adheres to the inner wall of the outer tub and the outer wall of the inner tub, and as a result mold is generated, resulting in contamination of the laundry. And the tank walls are difficult to clean.

Some manufacturers are making improvements in response to this situation. In order to save water resources, many washing machines use a non-porous inner tub and separate the inner and outer tubs so that water does not exist in the outer tub and only the inner tub holds water. ing. Also, a drain hole is formed near the upper end of the side wall of the inner tank. In this case, when the washing machine spins water, the centrifugal force causes the water to be shaken out to the inner wall of the inner tub, move upward along the inner wall of the inner tub, and then be discharged from the drain hole at the upper end of the inner tub. This improves the water-saving effect of the washing machine and saves the amount of detergent used.

However, the above scheme has the following problems. That is, since the washing machine rotates at a high speed during dehydration, the water in the clothes, when it is shaken out from the drain hole on the side wall of the inner tub, collides with the side wall of the outer tub and easily scatters in all directions. As a result, since water remains on the inner wall of the outer tank for a long period of time, it is easy for bacteria to grow, and it is not environmentally friendly.

Patent Literature 1 discloses a one-tank water-saving washing machine. The washing machine is provided with a water collection device at the mouth of the washing tub, and the water collection mouth of the water collection device surrounds the mouth of the washing tub along the washing tub. A water collecting chamber positioned at the mouth of the water collecting device is connected to a plurality of drain pipes arranged symmetrically from top to bottom along the outer wall of the washing tank. During dehydration, the water stream centrifuged by the high-speed rotation is collected by the water collecting device and guided downward for discharge. Although the structure does not include an outer tub, wash water first enters the water collecting device when the washing machine is dewatered. However, since the water collecting device has an annular structure and the cleaning water stored therein drains downward at different speeds, the balance is lost when the cleaning tank rotates at high speed. In addition, after entering the water collecting device, the washing water is concentrated at the center from the bottom of the washing tank and discharged, which is disadvantageous for drainage. As a result, the centrifugal force makes it difficult to discharge the water concentrated in the water collecting chamber, and the washing water concentrates on the upper end of the washing tank. In particular, when a large amount of water remains in the cleaning tank, most of the cleaning water is concentrated in the water collection chamber and is not discharged, so the center of gravity of the cleaning tank and the outer tank is raised, resulting in extremely large vibration and noise. occurs. In addition, the operating load of the dewatering motor also increases, making the motor more susceptible to damage.

In view of the above, the present invention is proposed.

Chinese Patent Application No. 99230455.5

The present invention eliminates the defects of the prior art, is capable of relatively increasing the volume of the washing tank, and is capable of improving the efficiency of water discharge by avoiding the concentration of washing water above the washing tank during dehydration. is a technical problem to be solved by providing

In order to solve the above technical problems, the basic idea of the technical solution adopted in the present invention will be described below.

A cleaning apparatus comprising a rotatable cleaning tank in which water is stored during cleaning and a spout provided on the top of the tank wall, and a water discharge guide member provided on the tank wall of the cleaning tank and communicating with the spout. and a water discharge guide member that guides and discharges water downward when water in the washing tank is swung out from an upper water discharge port and enters the inside of the water discharge guide member.

Additionally, the cleaning device includes a water stop. The water stop part is provided above the spout to stop the water from rising.

Further, the water stop portion may be constituted by the lower edge of the balance ring, or may be constituted by a structure in which the diameter of the opening at the top of the cleaning tank is reduced inwardly, or may be formed on the inner wall of the cleaning tank. It consists of an attached annular protruding rib.

According to the above structure, the discharge speed of cleansing water from the spout to the outside increases. In addition, the water shut-off part serves to change the direction of the cleansing water and guide the cleansing water to be discharged from the spout.

Further, the water discharge guide member is provided with a water guide chamber extending from top to bottom, and the upper part thereof communicates with the water discharge port. The radial width of the water guide chamber gradually increases from top to bottom.

Further, the water discharge guide member is provided with a water guide chamber extending from top to bottom, and the upper part thereof communicates with the water discharge port. The side wall of the water introduction chamber on the side away from the cleaning tank is provided so as to be gradually inclined from top to bottom in a direction away from the cleaning tank, preferably at an angle of 0 to 10°. , more preferably, the angle of the oblique installation is 1-3°. The above structure is advantageous for the downward discharge speed of the wash water. According to this, it is possible to prevent the wash water from flowing downward in the water conveying chamber due to the action of centrifugal force, and thus preventing the wash water from flowing upward in the reverse direction and concentrating in the vicinity of the spout.

Further, the water discharge guide member includes an outer housing. The outer housing is attached to the outside of the tank wall of the cleaning tank at a position corresponding to the spout, and has a certain gap between it and the tank wall of the cleaning tank, thereby forming a water guide chamber that guides water downward. forming. A water discharge port on the tank wall of the cleaning tank constitutes a water supply port of the water guide chamber, and a drain port is provided at the bottom of the water guide chamber.

Alternatively, the water discharge guide member includes a housing. The housing is attached to the outside of the tank wall of the cleaning tank, and the housing is provided with a water guide chamber for guiding water downward. A water supply port is provided corresponding to the water discharge port on the side of the housing adjacent to the cleaning tank. The water guide chamber communicates with the water discharge port through the water supply port, and is provided with a drain port at the bottom.

Alternatively, the washing tank has two layers of inner and outer tank walls. The two-layered tank wall is sealed at the top and has an opening at the bottom. The upper portion of the inner layer tank wall is provided with the water discharge port, and the gap between the two layers of tank walls constitutes the water guide chamber of the water discharge guide member.

Alternatively, the water discharge guide member further includes a hollow water guide chamber manufactured by bending and pressing the tank wall of the cleaning tank. A water supply port is provided in the upper part of the water guide chamber on the side corresponding to the cleaning tank, and a drain port is provided in the lower part.

Furthermore, the direction of the water discharge port is provided along the radial direction of the cleaning tank. This structure is advantageous for discharging the washing water, and can further increase the washing water spouting speed compared to the internal structure of the washing tank that discharges the washing water upward.

Further, an openable and closable water discharge mechanism is provided on the tank wall and/or the tank bottom below the water discharge port of the cleaning tank. The water discharge mechanism is in a sealed state during the cleaning process. According to this structure, some of the water in the washing tank is first discharged, and then the remaining water in the laundry can be discharged from the spout using the centrifugal force generated when the washing tank rotates. and the rate of dehydration is accelerated.

Furthermore, both the tank wall and the tank bottom below the spout of the cleaning tank are provided in a sealed manner.

Further, the inner surface of the tank wall of the cleaning tank is inclined in a direction away from the central axis of the cleaning tank from bottom to top, preferably at an angle of 0 to 15°. , more preferably, the angle of inclination is 1-10°. According to this structure, the speed at which the water in the cleaning tank rises along the tank wall is increased.

Furthermore, the upper part of the water discharge guide member is in direct communication with the water discharge port, and the lower part extends below the horizontal plane on which the bottom of the washing tank is located. Preferably, the direction of water discharge from the drain port at the lower portion of the water discharge guide member is downward or obliquely downward in a direction away from the central axis of the cleaning tank.

The structure described above is advantageous in discharging cleansing water from the lower portion of the water discharge guide member. According to this method, the cleaning water concentrates in the water discharge guide member, which raises the center of gravity of the cleaning tank, causing large vibrations and noise, and increasing the output load when rotating the cleaning tank. It is possible to avoid the situation.

Further, inside the water discharge guide member, a direction-changing water-conducting structure is provided for changing the direction of the water spouted radially from the water discharge port and guiding the water downward. Preferably, the diverting water conducting structure has at least one downward inclined surface or arcuate surface provided corresponding to the spout.

The above structure can play the role of stably changing the direction of the cleansing water, and prevents the cleansing water from rebounding and scattering within the water discharge guide member. This avoids the influence of the water discharge guide member on the downward water conveyance speed.

Further, the washing apparatus includes a water collecting part installed at the bottom of the washing tank to collect water discharged from the washing tank. The washing tank is rotatably provided with respect to the water collecting portion. The water collecting portion includes a bottom wall and a water collecting tank, and the lower end of the water discharge guide member extends into the water collecting tank. Furthermore, the water collection part is provided with a drainage mechanism for discharging the water in the water collection tank.

Further, the water collecting portion includes a side wall provided above the bottom wall and surrounding the entire circumference, the bottom wall and the side walls sealingly forming the water collecting tank.

Furthermore, the side wall satisfies the minimum height so that the water entering the collecting tank does not overflow when the washing tank rotates and drains. Preferably, the top of the side walls does not exceed 1/3 of the height from the bottom of the washing tank, more preferably the top of the side walls does not exceed 1/5 of the height from the bottom of the washing tank.

According to the above structure, collision with the tank caused by eccentricity of the upper portion during high-speed rotation of the cleaning tank is avoided, so that the volume of the cleaning tank can be relatively increased.

Further, the water collecting part has a tank body structure, the bottom wall is the bottom of the tank, the side wall is the peripheral wall, and is connected to the housing of the cleaning equipment via a damper. Preferably, an annular groove is provided in the tank bottom. The lower end of the water discharge guide member extends into the groove, and a drain port is provided at the lowest point of the groove.

According to the above structure, splashing of cleansing water is prevented when the cleansing water is guided.

Alternatively, the water collecting tank is an annular groove provided on the bottom wall.

Further, there are at least two water discharge guide members, each of which is independently distributed uniformly on the tank wall along the circumferential direction of the washing tank.

The present invention further provides a cleansing water discharge method that improves water discharge efficiency. In the process of rotating the washing tank, the washing water inside rises along the inner wall of the washing tank, reaches the outside of the washing tank through the upper spout, and is guided downward by the water discharge guide member on the washing tank and is discharged. be.

The washing machine of the present invention includes pulsator washing machines, drum washing machines, washer/dryer integrated machines, tableware machines, and other machines that require washing water to be discharged by centrifugal force.

By using the above technical solutions, the present invention has the following beneficial effects compared with the prior art.

In the cleaning equipment of the present invention, the cleaning tank is used as it is as a water tank. Therefore, the usage rate of cleaning water can be improved, and the amount of cleaning water used is reduced, so the amount of cleaning liquid used is relatively reduced. In addition, since the structure surrounding the upper half of the cleaning tank with the outer tank is omitted, the volume of the cleaning tank can be increased. Along with this, the amount of laundry can also be increased, and the purpose of expanding the capacity of the washing machine is achieved. Further, the water discharge guide member communicates directly with the inside of the cleaning tank, and directly guides the water inside the cleaning tank downward. As a result, the water discharge efficiency is improved, so that it is possible to avoid a situation in which the cleaning water concentrates on the upper end of the cleaning tank and disturbs the balance during rotation of the cleaning tank. Therefore, the rotation of the washing tank becomes more stable, and the noise during operation is further reduced. Also, the service life is longer.
