Description

Microwave Electric Rice Pot {A Microwave Electric Rice Pot}

The present invention relates to an electric rice cooker using microwave waves, and more particularly, to a microwave electric rice cooker to be cooked to be quickly cooked due to the microwave wave and various kinds of cooking functions are performed.

In recent years, the use of cookware, which has been developed to enable fast and convenient cooking, is increasing day by day. In particular, the cookware may be a typical household appliances such as gas range, microwave oven, rice cooker, cooker.

Among them, electric rice cookers are widely used in most households to cook rice, which is a staple food of Koreans. In addition, microwave ovens are also used for rapid thawing, warming, and cooking of various foods other than rice.

In particular, the rice cooker is coupled to the main body 1, the lid 2 coupled to the upper portion of the main body 1 to open and close the inside of the main body 1, and the inner plate 3 in the main body 1 It is coupled to the space portion (3a) to be formed, the oven (4) is inserted into the space portion (3a) and mixed with rice and water, and the outer surface of the inner plate (3) cooking and warming A heat source 5 for providing a heat source necessary for the pressure, a pressure weight 7 installed above the lid 2 to adjust the pressure degree in the oven 4, and a pressure weight 7 provided in the lid 2. It is composed of a steam outlet (8) consisting of a valve (8a) to discharge the steam in the oven (4) to the outside of the body (1) in accordance with the movement of the.

Here, a temperature sensor 9 for sensing the temperature of the oven 4 is further installed below the inner plate 3.

Referring to the operation of the conventional electric rice cooker configured as described above are as follows.

First, the user inputs a command for cooking food through the operation control unit 10 installed on the outer surface of the rice cooker. According to the command, a microcomputer (not shown) which performs various control functions on the rice cooker cooks food contained in the oven 4 through the heat source 5.

The temperature sensor 9 installed on the inner plate 5 so as to be located at the bottom of the oven 4 senses the temperature of the oven 4. The microcomputer controls the rice cooker according to the temperature sensed by the temperature sensor 9 to allow food to be cooked.

In particular, the pressure weight (7) is located at the upper end of the steam outlet (8) formed in the lid (2) moves in accordance with the pressure degree of the oven (4) and the steam in the oven (4) through the steam outlet (8) To be released to the outside.

However, the electric rice cooker configured as described above has a problem in that it takes a long time to heat the inner container 3 and the oven 4 by cooking the food by applying heat through the heat source 5 directly with food.

In addition, in the case of the conventional electric rice cooker, although it takes a lot of space, it is generally used only when cooking rice has a problem that the constraints to secure the space for various food cooking.

The present invention has been made to solve the above problems of the prior art, an object of the present invention is to provide a microwave electric rice cooker capable of cooking a variety of food in a limited space at the same time to enable fast cooking of food.

According to a feature of the microwave electric rice cooker according to the present invention for solving the above problems, the inner plate portion to form a cavity (Cavity) to hold the food to be cooked, and the microwave wave to cook the food The microwave is installed in the magnetron to generate, the waveguide for guiding the microwave wave generated in the magnetron to the inner plate portion, and the irradiation hole for irradiating the microwave wave with the cavity formed in the inner plate portion from the waveguide. Dispersing means for dispersing the microwave wave to be evenly delivered to food, and an outer plate portion for forming an appearance so that the microwave wave irradiated to the inner plate portion is not emitted to the outside.

In particular, the dispersing means is composed of a stirrer for rotating the microwave wave so that the microwave wave is dispersed, and a motor unit provided on the rotating shaft of the stirrer so that the stirrer is rotated.

In addition, the outer plate portion has a pressure weight for adjusting the pressure of the cavity so that the food is cooked at a predetermined pressure, a steam outlet for ejecting steam generated when the food is cooked to the outside, the pressure weight and the steam outlet Microwave leakage shield is installed to prevent the external emission of microwave waves through.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 2, the electric rice cooker according to the present invention can cook food contained in the inner plate part 10 and the inner plate part 10 to form a cavity 10a for cooking food (F). A magnetron 11 for generating microwave waves, a waveguide 12 for inducing the microwave waves so that the microwaves generated from the magnetron 11 are transmitted to the inner plate part 10, and the Dispersion means 13 is installed so that the microwave wave is dispersed in the irradiation hole 12a for irradiating the microwave wave with the food located in the cavity in the waveguide 12, and the appearance of the microwave wave is not emitted to the outside It consists of the outer plate part 14 which forms.

In particular, the dispersing means 13 is distributed and irradiated through a stirrer 15 and a constant stirrer 15 installed in the waveguide toward the irradiation hole 12a as shown in FIG. 3. The motor unit 16 is installed on the rotating shaft of the stirrer 15 so as not to obstruct the path of the microwave wave to rotate the stirrer 15.

The stirrer 15 that rotates according to the driving of the motor unit 16 has the microwave wave 12a of the waveguide 12 so that the microwave wave of the waveguide 12 is evenly transmitted to the food. Through the distributed irradiation to the cavity (10a) through.

In addition, the outer plate portion 14 is provided with a pressure weight 17 for adjusting the pressure in the cavity 10a, and a steam outlet 18 to which the lower end of the pressure weight 17 and the cavity 10a are connected. . Therefore, the food in the cavity 10a can be cooked at a predetermined pressure, thereby improving the quality of the cooked food.

The pressure weight 17 is fine due to the pressure formed in the cavity 10a and allows the pressure of the cavity 10a to be adjusted. The steam outlet 18 is opened and closed in response to the fine movement of the pressure weight 17 so that the steam of the cavity 10a is discharged to the outside.

In addition, the outer plate portion 14 is provided with a microwave leakage shield 19 having a mesh structure so that microwaves distributed and irradiated to the inner plate portion 10 are not emitted to the outside.

Looking at the operation of the present invention configured as described above are as follows.

First, the user opens the outer plate portion 14 and places food to be cooked on the inner plate portion 10. And a key is input so that a desired cooking function is performed through the operation manipulation unit 20 installed in the outer plate portion 14.

A microcomputer (not shown) that performs various control functions on the microwave rice cooker according to the input key operates the magnetron 11 to generate microwave waves.

Thereafter, the generated microwave wave is guided to the irradiation port 12a through the waveguide 12. The induced microwave wave is distributedly irradiated into the food of the cavity 10a through the stirrer 15 that is rotated by the motor unit 16.

The microwave wave irradiated through the stirrer 15 is irradiated evenly to the food of the cavity 10a to cook the food.

Microwave electric rice cooker of the present invention constituted as described above by installing a magnetron to cook the food placed in the electric rice cooker through the microwave generated from the magnetron, to enable rapid cooking of food at the same time various kinds of cooking in a limited space By making it possible to have an effect that can increase the utility of the product.
