The present invention relates to a combo-type dishwasher, and more particularly, in a state in which dishes are immersed in washing water, ultrasonic waves can be effectively transmitted so that the first washing can be performed, and the washing water is sprayed with high pressure while the dishes are floating in the washing water. After cleaning the tableware for the second time, the tableware can be dried efficiently using heat, and the washing water used for the primary washing is purified and reused as the secondary washing water to increase the water saving effect, and the elevating structure of the basket for holding the tableware is improved. It relates to a combo-type dishwasher that can increase the space utilization by miniaturizing the product.

In general, a dish washing apparatus has a dish washing room formed inside a hexahedral case, and a rack serving as a storage basket for accommodating dishes is installed in the dish washing room, or a plurality of grills for storing dishes are stacked and installed.

In addition, the dishes are washed by a plurality of spray nozzles that spray water toward the rack or grill from the upper and lower portions of the dish washing room, and the dish washing device accommodates the dishes in a device equipped with a detergent and washing water supply device. It is operated to automatically wash dishes for a predetermined washing time, and is widely used in general restaurants that handle a large amount of dishes.

Since a large amount of water and detergent are used to wash the dishes in the conventional dish washing apparatus, there is a problem such as water pollution due to excessive use of water and detergent.

In order to reduce the amount of washing water used and increase washing efficiency, an ultrasonic dishwashing device that washes dishes by generating ultrasonic waves according to micro-vibrations in the washing water while the dishes are immersed in the washing water of the washing tank has been developed.

As a related prior art, there is a representative utility model registration No. 20-0292079 “ultrasonic dishwashing device”.

However, the conventional ultrasonic dishwashing apparatus such as the registered utility model has the inconvenience of separately performing rinsing and drying operations after taking out the dishes after ultrasonic cleaning.

As an alternative to this, a separate rinsing means and a drying means are additionally installed inside the conventional ultrasonic dish washing machine such as the registered utility model, and after washing, in a state in which the washing water is completely drained, the washing water is sprayed at high pressure to the dishes, rinsed and dried There is a dishwashing device that allows this to be done. This alternative dishwashing device completely drains the washing water used for ultrasonic washing, so the amount of washing water used is very large, and rinsing and drying only after draining the used washing water is complete. In addition to taking a long time to clean, there is a big problem in that there is a great concern of malfunction or failure due to water leakage due to the overlapping installation of the ultrasonic generating means, the rinsing means and the drying means.

On the other hand, in general, an ultrasonic vibrator is a device that generates vibration in an ultrasonic frequency band (about 20,000 Hz or more) when electricity is applied, and in the product field, the cleaning effect by vibration can be seen through a washing machine, a skin massager, a toothbrush, etc. is being utilized

Among the vibrators to which such a piezoelectric element is applied, the Lanjuban-type vibrator is widely used by being applied to a washing machine. The Lanjuban-type vibrator has a structure that expands the vibration by attaching a metal material to the piezoelectric element. Radial vibration is converted into longitudinal vibration through the metal attached to both sides of the piezoelectric element, and the vibration is transmitted to the inside by expanding.

Looking at the structure of the washing machine in which such a Lanjuban-type vibrator is combined, in general, the upper surface of the Lanjuban-type vibrator is attached to the bottom of the water tank so that the vibration generated from the vibrator is transmitted to the water tank. A cylindrical vibrator is attached to the bottom of the tank.

However, in such a coupling structure, since the vibration generated from the vibrator has straightness, the vibration proceeds only in a single direction, showing a limitation in cleaning power.

A configuration for overcoming such limitations is disclosed in Korean Patent Registration No. 10-0242912. Korean Patent Registration No. 10-0242912 relates to a central radiation ultrasonic dishwasher, which generates ultrasonic waves into a washing tub filled with washing water to automatically wash a plurality of dishes contained in the washing water, the ultrasonic waves. The device for generating air is in the shape of a U-shaped tube having an open end and a closed end, and the outer periphery of the open end and the inner surface of the washing tub are airtightly connected, and the inside communicates with the outside of the washing tub through the open end. and one or more U-shaped vibrating tubes installed so that the closed end side protrudes from the inside of the washing tank, and one or more vibrators installed to be attached to the inside of the U-shaped vibrating tube, converting electrical energy into mechanical vibrations to generate ultrasonic waves do.

According to such a configuration, in an ultrasonic dishwasher that automatically washes a plurality of dishes by generating ultrasonic waves in washing water, the vibrator, which is an ultrasonic generator, can be stably fixed, and ultrasonic waves can be transmitted effectively, so that the washing ability is improved. has an improving effect.

However, the invention has a limitation in that it is merely a simple change of the shape of the water tank provided in the dishwasher, and has a disadvantage in that the inner space of the water tank of the dish washing machine is also narrowed because the central part of the water tank protrudes.

In addition, in the case of a washing machine provided with such a vibrator, there is a disadvantage in that the transmission efficiency of vibration generated from the vibrator is different depending on the coupling structure between the vibrator and the washing machine.

Thereafter, the washing water of the second water supply tank 52 by the pump 53 is supplied to the first injection unit 30 and the second injection unit 40 by the pumping operation of the pump 53 and used for the first washing. The washing water is sprayed on the dishes to perform the secondary washing, and the primary rinsing operation is performed.

When the first rinsing operation is completed, the washing water (hot water) of the first water supply tank 51 is supplied to the first injection unit 30 and the second injection unit 40 by the pumping operation of the pump 53 to be washed. As clean unused washing water is sprayed onto the dishes, the third washing is performed and the secondary rinsing operation is performed.

At this time, washing water may be supplied to the first spray unit 30 for a predetermined period of time to wash dishes, and then, washing water may be supplied to the second spray unit 40 for final washing. The time, order, number of times, and the like, of washing water spraying in the spraying unit 30 and the second spraying unit 40 may be changed and set in various ways.

Washing water falling into the washing tank 11 while being used for the first and second rinsing of these secondary washings is no longer drained into the second water supply tank, but outside the washing tank 11 through a separate drain means or an overflow drain hole. is emitted as

On the other hand, when the washing through the first spraying unit 30 and the second spraying unit 40 is completed, the air supplied to the inner space of the door 13 by the blower becomes hot air while being heated by the heater and is buried on the dishes. Dry and remove excess water.

When the drying of the dishes is completed, the user opens the door 13 to collect the dishes that have been washed and dried, puts other dishes that need washing in the basket 12, and then restarts the combo-type dishwasher 1, The above-described operation is repeated to wash the dishes, and at this time, the amount of water used for washing the dishes can be reduced by reusing the washing water used for the primary washing for the primary rinsing (primary rinsing) of the secondary washing every time it is washed. By properly mixing the filtered washing water and the washing water before use, it is possible to clean and complete washing with water saving.
