Description

Description: TECHNICAL FIELD [0001] The present invention relates to a dishwasher.

2. Description of the Related Art An additive solution such as a detergent solution or a rinse aid solution is formed from a dishwashing additive such as a solid detergent or a solid rinse aid, and is known in dishwashers using the same. is there.

Further, a solid detergent container provided with a dishwasher and containing a solid detergent is detachably attached, and selectively supplied water is spouted toward the solid detergent in the solid detergent container to form a detergent solution. Means for supplying a detergent solution to a dishwasher are also known.

For a conventional dishwasher of the kind described above, 3
Water is supplied by this line. The first line is used to supply washing hot water to the dishwasher,
The second line is used to form a detergent solution from a solid detergent and the third line is used to form a rinse aid solution from a solid rinse aid.

In various places in the country, the pressure of water used varies, so that each of the three lines is provided with a pressure control valve and a pressure gauge in addition to the vacuum breaker.

An opening is formed on one end surface of a container having a water jet nozzle which is provided in a dishwasher and jets water upward, and a detergent container containing a detergent is turned downward. U.S. Pat. No. 4,020,865 and U.S. Pat. No. 244,598 disclose reversible detergent solution supply means.

In this conventional reversing type detergent solution supply means, 5 to 10 gallons of powdered detergent are contained in a detergent container, and this is converted into a concentrated detergent solution by water jetted from a water jet nozzle of a retainer.

In the reversing type detergent solution supply means of U.S. Pat.No. 4,020,865, only a specially shaped detergent container having a depression at a predetermined position on the outer peripheral surface is attached to the holder, and this special Water is jetted from the water jet nozzle for forming the detergent solution only when the shaped detergent container is attached to the holder.

Further, in the reversing type detergent solution supply means of U.S. Pat. No. 4,020,865, before the detergent dispenser is inverted to the vertical position by the cradle mechanism and attached to the holder, the fixed engagement of the fixed safety mechanism must be released. . The fixed safety mechanism prevents water from being ejected from the water ejection nozzle of the cage.

[Problems to be Solved by the Invention] The conventional dishwasher as described above requires three water supply lines, and each of the three water supply lines has a pressure control valve and a pressure in addition to a vacuum breaker. Since a gauge needs to be provided, the cost required for installing a dishwasher is high. In addition, since the solid washing supply means and the solid rinse aid supply means are installed separately from the main container of the dishwasher, the tableware for tableware is taken in and out, so a relatively large area is required as a place for installing the dishwasher. As a result, the degree of freedom in selecting the location of the dishwasher is reduced.

Further, in the conventional dishwashers of the above-mentioned type, a large amount of waste water is consumed for dishwashing additives such as a solid detergent and a solid rinse aid used in water, and a large amount of dishwashing additives are consumed.

This means that when the dishwasher is used, first, a few gallons of clean hot water are supplied from the first line to the bottom of the main container into which the tableware of the dishwasher is put in and out, and are almost completely filled. Then, since the additive solution formed from the solid detergent and the solid rinse aid is supplied to the main container by the water supplied from the second or third line, the amount of liquid in the pool is reduced to a predetermined amount. This is because the liquid in the reservoir, which has been increased to a predetermined amount or more, is discharged from the main container by an overflow valve provided in the reservoir.

The present invention has been made under the above circumstances, and an object of the present invention is that the cost required for installation is low, a relatively large area is not required as an installation place, the degree of freedom in selecting an installation place is large, and An object of the present invention is to provide a dishwasher that consumes less consumption of dishwashing additives.

[Means for Solving the Problems] In order to solve the above-mentioned object of the present invention, a dishwasher according to the present invention comprises: tableware for putting in and out, and a bottom provided with a pool for collecting water and residues. A water supply means having a valve and a vacuum breaker for supplying water to the main container; an opening top disposed below the reservoir of the main container and connected to a bottom of the reservoir of the main container; And a cylindrical metal case having an opening bottom provided with a drain valve and a perforated cylindrical filter housed in the cylindrical metal case. First filter means for discharging the water to the outside from the metal case through the open bottom of the metal case when the residue is introduced into the cylindrical filter by gravity through the open top of the metal case and the drain valve is opened; ; Metal of the first filter means Connected to the case above the drain valve of the first filter means,
A main pump to which water is supplied from the metal case when the drain valve is closed; and a main pump arranged in the main container and connected to the main pump and facing tableware put in the main container. Nozzle means for ejecting pressure water from the pump to bring the pressure water into contact with tableware; disposed above the main container and connected to the main container and the main pump, through which the pressure water from the main pump passes; Second filter means for allowing water to flow to the main container by gravity when the main pump is not operating; and pressure containing the solid detergent and being coupled to the second filter means and from the second filter means. A valve for selectively supplying water to the solid detergent for a predetermined time to form a detergent solution; and a detergent solution supply means connected to the main container and supplying the detergent solution to the main container. Is characterized by .

[Operation and Effect] In the dishwasher according to the present invention, which is configured as described above, when tableware is put in the main container and washing is started, water pressure fluctuations in various parts of Japan are adjusted. A predetermined amount of clean water is supplied to the main vessel from a water supply means having a valve for vacuum and a vacuum breaker, collected in a pool at the bottom of the main vessel, and the metal of the first filter means having a drain valve closed. After being introduced into the cylindrical filter by gravity through the top opening of the case, it reaches the main pump.

The main pump supplies pressurized water to the nozzle means, and the nozzle means blows out the pressurized water toward the tableware contained in the main container to bring the pressure water into contact with the tableware.

The pressurized water from the main pump also passes through the second filter means and is selectively supplied to the detergent solution supply means for a predetermined time via a valve of the detergent solution supply means. And supply it to the main container.

The detergent solution supplied to the main container is mixed with the clean water previously supplied in the reservoir at the bottom of the main container, sent from the reservoir to the main pump via the first filter means, and further passed through the nozzle means. Is blown out toward tableware in the main container.

After a predetermined time of washing with the water mixed with the detergent solution, the main pump is stopped, and the water mixed with the detergent solution collected in the pool at the bottom of the main container is opened by the drain valve of the first filter means and the first pump is opened. Is discharged outside the filter means.

As described in detail above, a predetermined amount of the detergent solution is formed from the solid detergent by a part of the predetermined amount of clean water supplied to the main container from the water supply means. The mixed water will not exceed a predetermined amount.For example, even if the pool is provided with an overflow valve, the water mixed with the detergent solution in the pool at the bottom of the main container is discharged to the outside by the overflow valve. There is no.

This reduces the consumption of dishwashing additives.

Also, the number of water supply means may be one, and thus the number of valves and vacuum breakers provided for adjusting water pressure fluctuations in various parts of the country in the water supply means may be one.

This not only reduces the cost required for installing the dishwasher, but also does not require a relatively large area as an installation place, and further increases the degree of freedom in selecting an installation place.

In the dishwasher according to the present invention, which is configured as described above, a solid rinse aid container containing a solid rinse aid is provided in the main container, and the solid rinse aid container has The pressurized water from the second filter means is selectively supplied through the valve, and the pressurized water supplied from the second filter means is jetted to the solid rinse aid to form a rinse aid solution, A rinse aid solution is supplied to the container,
Is preferred.

The rinse aid solution is the same as the detergent solution from a predetermined amount of clean water supplied to the main container from the water supply means after washing the tableware with water mixed with the detergent solution formed from the solid detergent. As in the case of washing tableware with water mixed with a detergent solution formed from a solid detergent, rinsing of tableware with water mixed with a rinse aid solution is performed by the main pump and nozzle means. This is performed for a predetermined time.

When the rinsing of the tableware is completed, the tableware is removed from the main container.

After the rinsing, the tableware is disinfected with a chlorine-based disinfectant, but this disinfection can be performed inside or outside the main container.

The water mixed with the rinse aid solution after the rinsing is different from the water mixed with the detergent solution formed from the solid detergent after the washing of the tableware has been completed, unlike the drain valve of the first filter means. Is not discharged outside the first filter means.

The water mixed with the rinse solution after the rinse is used to form a detergent solution for washing tableware next to the main container from the solid detergent.

In other words, the detergent solution for washing the tableware put in the main container after the second time uses water mixed with the rinse aid solution used for rinsing the tableware put in the main container last time. It does not use clean water formed from a solid detergent and supplied to the main container from the water supply means.

This is one of the solutions to the water resource consumption problem, as well as reducing the amount of clean water used by the dishwasher and lowering the operating cost of the dishwasher.

If the drainage valve of the first filter means is opened after washing and rinsing of the tableware for a desired number of times, water mixed with the rinse aid solution can be discharged to the outside of the first filter means. Then, the washing of the tableware put in the main container can be performed by using clean water supplied to the main container from the water supply means.

In the dishwasher according to the present invention, the detergent solution supply means further comprises a funnel-shaped holding portion fixed to the main container, and a solid detergent removably received on a funnel-shaped surface of the funnel-shaped holding portion. And a solid detergent container accommodated therein, and pressurized water is selectively supplied to the holding portion from the second filter means via the valve for a predetermined time, and is sprayed toward the solid detergent in the solid detergent container. After the detergent solution is formed, after the predetermined amount of the detergent solution is formed, pressure water is selectively supplied along the maximum opening edge of the funnel-shaped surface of the holding portion, and the detergent solution on the funnel-shaped surface of the holding portion is discharged. It is preferable to perform washing.

In the detergent solution supply means having such a configuration, the solid detergent container removably received in the holding portion facilitates the operation of supplying the solid detergent to the detergent solution supply means, and the solid detergent to the surroundings during the receiving operation. To prevent splattering and clean the receiving work.

Further, the pressurized water selectively supplied along the maximum opening edge of the funnel-shaped surface of the funnel-shaped holding portion to wash the detergent solution on the funnel-shaped surface of the holding portion enhances the use efficiency of the detergent solution.

In the dishwasher according to the present invention, the detergent solution supply means further comprises: a solid detergent, an opening is formed in the end surface, and an outer peripheral surface extends from the end surface near the end surface along the center line of the opening in the end surface. A solid detergent container formed with a protruding depression; a holding portion fixed to the main container and removably receiving the opening at the end face of the solid detergent container; provided on the holding portion, a valve provided from the second filter means. The pressurized water is selectively supplied through the opening of the solid detergent container while the opening of the solid washing container is received in the holding portion, and the pressurized water is selectively supplied to the solid detergent in the solid detergent container. A nozzle for squirting to form a detergent solution; operable by receiving said opening of the solid detergent container by the holding portion to allow a selective supply of pressurized water to the nozzle via a valve from the second filter means. , Water supply control means for cutting off the supply of pressurized water to the nozzle via the valve from the second filter means by removing the solid detergent container from the holding portion; and a frame for detachably holding the solid detergent container. A holding portion rotatable between a closed position in which the opening of the solid detergent container is attached to the holding portion and an open position in which the opening of the solid detergent container is inverted from the closed position and detached from the holding portion. And a container supporting means attached to the holding means; wherein the frame of the container supporting means is attached to the holding part via a hinge, and the closed position overlaps the holding part and the open position which is turned over and away from the holding part. Has a diameter smaller than the diameter of the outer peripheral surface of the solid detergent container, and the end surface of the solid detergent container holds the opening of the end surface when arranged in the closed position. Part of nozzle A first annular member mounted face-to-face; concentrically disposed substantially parallel to the first annular member, having a diameter greater than the diameter of the outer peripheral surface of the solid detergent container; A second annular member disposed farther from the holding portion than the first annular member when the first annular member is disposed in the closed position;
And extends from the second annular member to a side opposite to the first annular member along a center line of a space surrounded by the second annular member, and the container supporting means is disposed in the open position. An axially extending portion for detachably holding the outer peripheral surface of the solid detergent container when the opening and closing position is rotated between the open position and the closed position; and at least the first annular member and the second annular member. The solid detergent container is attached to one side and protrudes inward in the radial direction of the space surrounded by the at least one from the at least one, and the outer periphery of the solid detergent container while the solid detergent container is detachably held by the frame of the container supporting means. A projection which is received in the recess of the surface and prevents the solid detergent container from rotating in its circumferential direction; mounted on the extension end of the axial extension and the first annular member is located in the open position When opened and open position When pivoted between the closed position and the solid detergent container, the solid detergent container detachably supports the bottom surface opposite to the end surface where the opening is formed, and when the first annular member is disposed at the open position.

In the detergent solution supply means having such a configuration, an opening is formed in an end face for accommodating a solid detergent, and a dent extending along the center line of the opening of the end face from the end face is formed near the end face on the outer peripheral face. The solid detergent container being operated by receiving the opening of the solid detergent container by the holding portion to allow the selective supply of pressurized water to the nozzle via the valve from the second filter means; Removing the supply of pressurized water to the nozzle via the valve from the second filter means by removing the solid detergent container from the
The water supply control means prevents water from being ejected from the nozzle when the solid detergent container having a predetermined shape is not received in the holding portion, so that a person or an object around the detergent solution supply means can receive water from the nozzle. To prevent any damage caused by unexpected squirting.

This is important because the water ejected from the nozzles is usually heated to a high temperature to facilitate dissolution of the solid detergent.

Since the water supply control means described above automatically sets the operation for permitting water ejection from the nozzle required for starting use by receiving the opening of the solid detergent container with respect to the holding portion, the water supply control means for ejecting water from the nozzle required for use start It is possible to prevent the operation of the automatic cleaning device from being wasted due to forgetting the allowable operation.

The container supporting means of the above-described detergent solution supply means includes a frame for detachably holding the solid detergent container, and the solid detergent is turned over from a closed position where the opening of the solid detergent container is attached to the holding portion and from the closed position. Attached to the holding portion so as to be rotatable between an open position where the opening of the container is detached from the holding portion, and is configured as a so-called inverted type, so that the mounting of the opening of the solid detergent container with respect to the holding portion, That is, the receiving operation is facilitated, and the receiving operation is simplified by preventing a part of the solid detergent from scattering around.

The inverted container supporting means is also advantageous when checking the state of the solid detergent inside the solid detergent container through the opening of the solid detergent container.

This is because the opening of the solid detergent container can be turned upward by inverting the container supporting means from the closed position to the open position, so that the solid detergent container is supported by the container supporting means. This is because the state of the solid detergent inside the solid detergent container can be safely confirmed from above through the opening.

If the container supporting means is not the reversing type, a large amount of effort and time is required to remove the solid detergent container from the holding portion and further turn the opening upward, so that the solid detergent container is spared with this effort and time. The state of the solid detergent inside the solid detergent container may be checked from below through the opening while simply lifting upward from the holding part and keeping the opening facing downward, thereby allowing the observer to check the state of the eyes of the observer. In some cases, the detergent solution dropped from the inside of the solid detergent container may enter and damage the eyes of the observer.
