Description

The present invention relates to a dishwasher for washing and drying used dishes.

Conventionally, a dishwasher has a water tank having a heater, and heated washing water is circulated by a pump from the water tank to perform washing. Detergent is also added to the water stored in the aquarium, and the cleaning power is effectively exerted by heating. This washing is performed by injecting water from below the basket in which the dishes are set by a plurality of injection nozzles.

In general, the water in the aquarium is replaced 2-3 times for rinsing, and finally heating and rinsing is performed. After that, the water is drained and blown with a fan, and a heater is used according to the temperature inside the refrigerator. It is designed to dry while controlling the temperature.

However, in this conventional dishwasher, the drying after washing is performed by the residual heat in the refrigerator and the heating by the heater, so that it takes a lot of time and the electricity cost for that is also high, so that the tableware can be used. Since the adhering water droplets are dried as they are, water droplet traces remain. This water droplet mark is especially noticeable on transparent cups, glasses, and other dishes and containers.

The applicant searched the preceding technical documents for the invention of the present application, but could not find any documents that seemed to be particularly related to or similar to the invention of the present application.

The problem to be solved by the present invention is that the conventional dishwasher requires a lot of time and electricity bills because the conventional dishwasher is dried by the residual heat in the refrigerator and the heating by the heater after washing. Since the water droplets adhering to the water droplets are dried as they are, water droplet traces remain, and the appearance cannot be said to be clean.

In order to solve the above-mentioned problems, the dishwasher according to the present invention is provided with a water tank equipped with a heater at the bottom of the refrigerator body, and water is pumped from the water tank by a pump and jetted from a nozzle to wash the dishes. In a dishwasher, the above-mentioned nozzle is provided with an injection nozzle not only from below the set tableware but also from above, and at least an air injection nozzle is also provided adjacent to the injection nozzle from above . In the dishwasher, the water injection nozzle and the air injection nozzle from above are set in one holder, and the holder is inserted with the first guide bar that is movable in the lateral direction. The holder is characterized by being rotatable in the horizontal direction .

Further, in the dishwasher according to the present invention, the rotation of the holder is permitted because the notch for avoiding collision with the first guide bar is formed at the opening edge of the insertion hole of the first guide bar. The notch is characterized in that it has a fan shape, and support portions are provided at both ends of the first guide bar, and the support portions are orthogonal to the first guide bar. Therefore, it is characterized in that a pair of second guide bars that make the holder movable in the front-rear direction are inserted .

Further, in the dishwasher according to the present invention, the water injection nozzle from below is provided with a basic turntable, and a plurality of sub-turntables are provided at the end of the basic turntable, and the plurality of subs are provided. The feature is that the turntable is provided with a plurality of sub-turntables with the injection ports facing upward, and the above-mentioned sub-turntables are provided with two at a pitch of 180 degrees across the center of the basic turntable. It is a feature.

The dishwasher according to the present invention is characterized in that the dishes and bowls are set and the supporting members that support the dishes and bowls are movable in position in order to adjust the distance between the dishes and bowls. A shelf portion for setting a cup or a glass is formed above the supporting member to be supported, and the shelf portion is characterized in that it is composed of a net.

Further, the dishwasher according to the present invention is characterized in that a plurality of the above-mentioned holders are arranged in a row, and the above-mentioned air injection is detected by a sensor even when the dishes are taken out after washing and drying. It is characterized by re-execution .

The dishwasher according to the present invention is configured as described above. Therefore, the washing water is sprayed from the vertical direction of the target tableware and bathed, and it spreads evenly. In addition to the residual heat and the heating effect of the heater, the water droplets remaining on the tableware are attached to the tableware. Can be blown off, leaving no traces of water droplets, and a clean finish can be achieved.

It is a schematic front view which shows the inside of the dishwasher which carried out this invention. It is a front view which shows the holder and the first guide bar. It is a top view which shows the holder and the 1st and 2nd guide bars. In the plan view which shows the support member of the tableware, (A) is the initial state, and (B) is the state which was slid to the use state.
