Description

Multifunctional microwave oven with dishwashing function {Multirole microwave oven having device for washing dishes}

The present invention relates to a multi-functional microwave oven, and more particularly, a water supply and drainage device for washing dishes is provided at the bottom of the microwave oven.

In general, a microwave oven (MWO) is a device for cooking food by the heat of intermolecular friction generated by disturbing the molecular arrangement of food by using a high frequency (about 2,450 MHz per second) as a heating source.

In particular, the multifunction microwave oven combines the microwave function as well as the convection function of cooking by the heat of the heater, and a combination function of the microwave function and the convection function.

As shown in FIG. 1, the multifunction microwave oven includes a main body 1, a base plate 2 on which the main body rests, and an U bent outcase 3 covering the upper and both sides of the main body 1. ), A door 4 and a control panel 5 installed on the front surface of the main body 1.

In addition, one side of the main body 1 is provided with a cooking chamber 6a which is a food cooking space, and the other side is provided with an electric chamber 7 in which various components necessary for driving the microwave are collected.

In addition, a heater 8 that generates heat when the above convection function is operated is installed at an outer upper portion of the cooking chamber so that the heater heat is introduced through a porous part (not shown) formed on the upper surface of the cooking chamber 6a.

In addition, the electric component chamber 7 is provided with main components such as a magnetron 9, which is a high frequency oscillation device, and a transformer 10 for transforming household power into a high voltage required when the magnetron 9 is oscillated.

In addition, the cooling fan 11 connected to the fan motor (not shown) and the microwave generated from the magnetron 9 are guided to the cooking chamber 6a to cool the high heat generated when the magnetron 9 is started. An air duct (not shown) for guiding the flow air generated by the rotational force of the waveguide 12 and the cooling fan 11 to the cooking chamber 6a is also provided.

The multifunctional microwave oven having such a configuration operates the microwave oven by selecting any one of the microwave function, the convection function, and the combination function according to the type and condition of the food.

For example, if the microwave function is selected, a high frequency of about 2,450 MHz per second is oscillated from the magnetron 9 installed in the electric chamber 7 and the high frequency entered into the cooking chamber 6a through the waveguide 12 is the Diffuse reflection on the wall, incident throughout the food.

As a result, the food is heated and cooked by the intermolecular frictional heat generated while the molecular arrangement of the food is disturbed.

On the other hand, if the convection function is selected, the heater 8 installed on the outer upper part of the cooking chamber 6a generates heat, and this heater heat flows into the cooking chamber 6a through the porous portion formed on the upper surface of the cooking chamber 6a to convection the food. By heating.

Next, the water supply and drainage of the general dishwasher will be described.

2 is a cross-sectional view showing a water supply and drainage of a general dishwasher.

The water supply and drainage device of a general dishwasher includes a main body (not shown) constituting an outer case, a tub 20 constituting an inner case, and rotatably installed in the tub to spray water onto dishes to be cleaned. A water spray nozzle 23a, a water supply pump 21 for pumping water in the tub 20 to the water spray nozzle 23a, and a drain pump 22 for pumping and draining water in the tub 20 And an air chamber 24 and a pressure sensor 25 for guiding the air in the air to enter the drain hose (not shown) during water supply.

The water supply and drainage method of the dishwasher configured as described above is as follows.

When a user inputs a washing command, a water supply valve (not shown) is opened and washing water flows into the tub 20 through the water supply valve and the water supply hose (not shown).

When the wash water flows up to a certain level, the water supply is stopped and at the same time, the water supply pump 21 operates to pump the wash water in the tub 20 to the water spray nozzle 23a, and the water spray nozzle is a dish located in the tub 20. The washing process is performed by spraying the washing water.

At this time, there is a heat washing stroke as a detailed stroke of the washing stroke, and the heating washing stroke is a stroke for washing dishes with heated washing water.

Accordingly, a heater (not shown) is mounted on the bottom of the tub 20 to perform the heating and washing stroke, and the heater (not shown) is also used as a heat source for drying dishes in a drying stroke.

Subsequently, a drain pump 22 is driven to drain the wash water used in the washing stroke, and the wash water in the tub 20 is pumped and discharged to the outside through a drain hose (not shown).

Then, after performing the rinsing stroke, the heater (not shown) at the bottom of the tub is driven to dry the dishes, thereby completing the entire process related to dish washing.

However, in the past, the microwave oven and the dishwasher were required as separate devices, and each of them required separate installation space, which wasted a waste of unnecessary space in our living environment, which generally had a narrow space, and also economically doubled. It was. In addition, the microwave oven has a cumbersome aspect of cleaning the cooking chamber arbitrarily.

Accordingly, the present invention has been made to solve the above problems, an object of the present invention to provide a water supply and drainage device that can wash dishes in a multi-functional microwave oven to save space.
