Description

[Detailed Description of the Invention] This invention relates to a washing machine that cleans tableware and other objects to be washed by spraying a cleaning liquid in which detergent is dissolved and jetted from a nozzle onto the objects.

In a washing machine that sprays a cleaning liquid ejected from a nozzle onto an object to be cleaned, a washing machine in which detergent is dissolved in the cleaning liquid in advance, for example,
The one disclosed in Publication of Utility Model Publication No. 54-4855 is known.

This washing machine is a washing machine that sprays washing water from a tank from a nozzle to wash an object to be washed.A detergent tank is provided separately from the tank, and a part of the hot water for finishing washing is diverted during finishing washing. Dissolve the powder or granular detergent in the washing tank by supplying the appropriate amount to the detergent tank. Then, a detergent solution in which this detergent is dissolved is supplied to the tank through an overflow pipe provided at the upper part of the washing tank, and the detergent is mixed into the main washing water.

This washing machine uses the washing water in its tank.
Since the detergent liquid can be automatically supplied, it is easy to mix the detergent into the washing water.

However, although warm water for final washing is supplied to the detergent tank of this washing machine, the temperature of this hot water decreases over time to room temperature. Therefore, there is a problem in that it takes a long time for the powder or granular detergent in the detergent tank to be sufficiently dissolved. This problem becomes more noticeable when the temperature is low, such as in winter.

Since hot water is supplied to the detergent tank by a nozzle inserted deeply into the detergent tank, the detergent in the detergent tank is in an agitated state. Therefore, since granular detergent is supplied as is to the washing water in the tank, if you wash with that washing water within a short time after adding the detergent, the detergent will not be sufficiently dissolved. This causes a problem that the cleaning effect becomes low.

This invention solves the above problems by making it possible to maintain a high temperature of the water in the detergent container almost continuously while the washing machine is in use. The object of the present invention is to provide a washing machine that can easily dissolve detergent.

The washing machine of this invention is equipped with a mounting part for the objects to be washed, a nozzle arranged above and below the mounting part for performing main washing and finishing detergent exclusively or for both, and a tank for the main detergent liquid. Warm water is placed in the tank as a main cleaning liquid, and a detergent container is placed with its bottom inserted into the hot water serving as the main cleaning liquid, and the detergent liquid therein is allowed to overflow to the top of the detergent container. an outflow hole for supplying water to the tank; the cleaning container is attached to one end of a substantially horizontal bottom wall of the water injection container;
A branch pipe branched from a pipe for supplying hot water or water for finishing cleaning is opened above the other end of the water injection container, and powder or granular detergent is poured into the water injection container. .

This washing machine first supplies hot water from a tank to a main washing nozzle to wash an object placed on a mounting section. After this main washing is finished, clean hot water or hot water for finishing washing is supplied to the finishing washing nozzle to perform the finishing washing of the object to be washed. Powder or granular detergent is placed in the water injection container. It is being

Then, when finishing cleaning begins, hot water or part of the water for finishing cleaning is also supplied to one end of the water injection container through the branch pipe, and this hot water or water flows along the bottom wall of the water injection container. The detergent flows into the detergent container, and at this time, the powder or granular detergent contained in the water pouring container is flushed out and poured into the detergent container. In this way, the detergent container always contains detergent and water.

On the other hand, since the lower part of the detergent container is inserted into the hot water in the tank, the water in the detergent container is heated by the heat of the hot water, maintaining a high temperature state, and promoting the dissolution of the detergent in the detergent container. do. In this way, a highly concentrated detergent solution is formed in the detergent container.

During the final cleaning, this highly concentrated detergent liquid is overflowed from the outflow hole with hot water or water flowing into the detergent container from the water injection container, and is supplied to the main cleaning liquid in the tank.

The detergent container is attached to one end of the substantially horizontal bottom wall of the water injection container, and the hot water or water for final cleaning is discharged to the other end of the bottom wall of the water injection container, and the detergent container is disposed along the bottom wall of the water injection container. By pouring it into a detergent container, hot water or water flowing into the detergent container can prevent
By reducing the amount of water agitation in the detergent container, the amount of undissolved detergent flowing out is reduced.

An embodiment of the washing machine of this invention will be described with reference to the drawings.

In the figure, reference numeral 1 denotes a box-shaped washing machine main body, in which a mounting section 2 for objects to be washed is provided. This mounting section 2 is constructed by arranging metal rods at intervals and using a blind or net so that the cleaning liquid can pass through it in the vertical direction. Then, the mounting section 2 is

Reference numeral 3 denotes a door provided in a part of the main body 1 above the mounting section 2, through which an object to be cleaned can be placed on the mounting section 2 or taken out. Reference numeral 4 denotes a nozzle pipe for main cleaning, which is arranged at appropriate locations such as above and below, left and right of the mounting section 2. Reference numeral 5 denotes a main cleaning liquid tank provided at the bottom of the main body 1, and hot water therein is force-fed to the nozzle pipe 4 by a pump (not shown).
It is sprayed onto the object to be cleaned on the mounting section 2 to clean it.

The main cleaning liquid spouted from the nozzle pipe 4 is collected in a saucer 6 and returned to the tank 5 for repeated use. Reference numeral 7 denotes a strainer disposed below a drain port provided in a part of the saucer 6, which separates solid matter mixed into the main cleaning liquid. This strainer 7
If it is attached to the main body 1 in a drawer type, it will be easy to remove solid matter accumulated therein.
8 is an overflow pipe provided in the tank 5.

Reference numeral 9 denotes a water injection container (see Fig. 2) placed below the saucer 6 and above the tank 5, the bottom wall of which is approximately horizontal, and the detergent container 10 is attached with one end protruding downward. , and an overflow outlet 11 is provided at the top of the detergent container 10. Further, the detergent container 10 is configured such that its lower part is inserted into hot water as the main cleaning liquid in the tank 5. If the water injection container 9 is also made into a drawer type, it is easy to replenish the detergent container 10 with detergent, and when the water injection container 9 is made into a drawer type, the detergent container 10 is provided on the back side thereof.

Reference numeral 12 denotes a pipe for supplying hot water or water for finishing cleaning, and the hot water or water to this pipe is supplied from a water heater or directly with tap water. The final cleaning is performed by using the main cleaning nozzle pipe 4 or by providing a dedicated finishing cleaning nozzle pipe. When the nozzle pipe 4 for main washing is also used for finishing washing, a valve is provided at an appropriate position on the pipe to enable switching between the main washing liquid and hot or cold water for finishing washing.

Reference numeral 12 denotes a pipe for supplying hot water or water for final cleaning, and the open end of a branch pipe 13 branched from this pipe is placed above the end of the water injection container 9 opposite to the detergent container 10, and is used during final cleaning. It is configured such that hot water or a portion of water can be supplied to the water pouring container 9. Reference numeral 14 denotes an adjustment valve provided in the branch pipe 13, which makes it possible to adjust the amount of hot water or hot water supplied to the water supply container 9.

To wash tableware and the like using this washing machine, the tableware and the like are placed on the placing portion 2, hot water from a tank 5 is jetted out from the nozzle pipe 4, and the tableware and the like are sprayed with the hot water to be washed.

After this main cleaning is completed, the pipe 12
Clean hot water or water is supplied to the tableware, and the tableware, etc., is finished washed with it. At this time, some of the hot water or water supplied to the pipe 12 is transferred to the branch pipe 13.
The hot water or water flows along the bottom wall of the water injection container 9 and into the detergent container 1.
Flows into 0. At this time, the detergent contained in the water pouring container 9 is poured into the detergent container 10.

Furthermore, due to the hot water or water flowing into the detergent container 10, the highly concentrated detergent solution in the detergent container overflows from the outflow hole 11 and is supplied to the tank 5. The detergent liquid that has flowed into the tank 5 is in a slightly fluid state due to the hot water in the tank 5 and the hot water or water used for final cleaning flowing into it. The hot water is dispersed evenly throughout the detergent, and this hot water becomes the main cleaning liquid in which the detergent is dissolved. This main cleaning liquid is then used for the next main cleaning.

In this way, the detergent container 10 always contains detergent and water, but since the bottom of the detergent container 10 is inserted into the hot water in the tank 5, the heat of this hot water causes the detergent container 10 to be filled with detergent and water. Since the water in the detergent container 10 is heated and maintained in a hot water state, the detergent can be efficiently dissolved in the warm water in the detergent container 10 while main washing is being performed, without being affected by conditions such as the season. Therefore, a highly concentrated detergent solution can be reliably supplied to the tank 5 during final cleaning.

Then, put the detergent in the water pouring container 9, and pour it into the detergent container 10 with hot water or a portion of the water for finishing washing.
Therefore, if hot water or hot water is supplied to the water pouring container 9 little by little, it will flow quietly into the detergent container 10 without stirring the hot water inside, and the fluidized detergent will flow into the detergent container 10. can be allowed to settle to the bottom. Therefore, it is possible to reduce the amount of undissolved detergent flowing directly into the tank 5.

Although this embodiment shows a machine that cleans the object to be cleaned in a fixed position, it is also possible to use it in a washing machine that washes the object while being transported on a conveyor.

As described above, the washing machine of this invention has a detergent container attached to the lower side of one end of the almost horizontal bottom wall of the water injection container, and hot water or a portion of the water for finishing cleaning is supplied to the other end. is supplied to the main cleaning liquid tank by overflowing from the outlet hole at the top of the detergent container. Then, the powder or granular detergent placed in the water pouring container is flushed with the hot water or water and poured into the detergent container.

Therefore, the hot water or water supplied to the water injection container flows along its bottom wall and enters the detergent container, so it is recommended that the hot water or water in the detergent container be stirred by flowing gently into the detergent container. It is possible to make the detergent flowing from the water injection container into the detergent container sequentially settle to the bottom thereof. Therefore, it is possible to reduce the amount of undissolved detergent flowing out from the outflow hole of the detergent container and entering the tank.

Since the bottom of the detergent container is inserted into the hot water of the tank, the water in the detergent container is heated by the heat of the hot water of the tank, and the detergent container is heated without being affected by the season or other conditions. become and maintain that state.

Therefore, it is possible to promote the dissolution of the detergent that has flowed in from the water injection container, and when finishing washing starts and some of the hot water or water is supplied to the detergent container, the detergent in the washing container is dissolved. Since the detergent solution is highly concentrated, by overflowing it and supplying it to the tank, it is possible to quickly and evenly convert the hot water in the tank into a detergent solution. can be used as a cleaning solution at any time.
