Description

Hooded microwave oven {Ventilation hooded microwave oven}

The present invention relates to a microwave oven, and more particularly, a hood-use microwave oven in which a heater is mounted on a side of a cavity and electrical components are installed at a height similar to a vent motor.

Various kinds of apparatuses have been proposed to date as heating apparatuses for heating foods. The most primitive heating device is a container in contact with the heat source integrated, it is possible to cook the food by putting the contents to be cooked in such a container and applying heat.

In addition, many types of cooking apparatuses that use electric energy directly or indirectly have been developed. As an example, a microwave oven using microwaves as a heating source can be cited. A microwave oven is a cooking apparatus that generates microwaves using electricity to infiltrate a cooking object and heats the cooking object by causing molecular motion therein.

However, it has been pointed out that the conventional microwave oven cannot provide fast and high-quality cooking due to the unity of the microwave heating method and the limitation of the output. In order to solve this problem, the heater unit, which is an auxiliary heating source, is mounted on the upper or lower portion of the cavity.

A hood-use microwave oven (hereinafter, simply referred to as a microwave oven) provided with such a heating source is installed above the gas oven range and has a function of discharging heat or smoke generated in the gas oven range.

The configuration and operation of a conventional microwave oven will be described with reference to FIGS. 1 and 2.

As shown in the drawing, the cavity 1, which is a space where food is cooked, and the electric compartment 2 in which electric components for generating microwaves are installed are formed in the microwave oven.

The magnetron 5 is mounted on the side surface T toward the cavity 1 in the electric compartment 2, and the generated microwaves are introduced into the cavity 1. In order to oscillate the microwave, electrical components such as a high voltage transformer 6 and a high voltage capacitor 7 are installed on the bottom of the electric chamber 2.

In addition, a cooling fan assembly 10 is installed in the upper part of the electric compartment 2 to cool the electric component including the magnetron 5 and the high-pressure transformer 6 that dissipate high temperature heat during microwave oscillation.

A stirrer pan assembly 15 is formed on the side surface of the cavity 1 facing the side surface T on which the magnetron 5 is mounted. The stirrer fan assembly 15 has a stirrer fan installed therein

The microwaves oscillating from the magnetron 5 by the rotation of the 16 is cavity

(1) Spread evenly inside.

On the other hand, a convection heater 20 is installed on the upper surface of the cavity (1). The convection heater 20 serves to heat the food by transferring the hot air into the cavity (1). The convection heater 20 is a convection heater 21 and the convection heater that generates heat.

Convection fan assembly 22 for blowing hot air to the air (21) to create a hot air.

In addition, the exhaust motor assembly 30 is mounted to the rear side from the upper part of the cavity 1 and serves to exhaust the heat and gas from the cooker in the lower portion of the microwave to the outside.

When cooking in a microwave oven, a removable shelf 33 is installed in the cavity 1 when cooking food such as chicken, which needs to be heated evenly on the upper and lower surfaces, and the food is placed thereon and heated. Otherwise, the food is heated on the turntable 40 installed below the cavity 1, and the turntable motor 41 is mounted at the bottom for the rotation of the turntable 40.

The shelf 33 is a rectangular through-hole is attached to the rectangular frame at regular intervals horizontally and vertically.

In the microwave oven having such a configuration, when the power is applied and operated, the high voltage current is applied from the high voltage transformer 6 and the high voltage capacitor 7 installed in the electric chamber 2 so that the magnetron 5 is microwaved. Will oscillate. The microwave flows into the cavity 1 and uniformly spreads into the cavity 1 by rotation of the stirrer pan 16 of the stirrer pan assembly 15 formed on the side of the cavity 1 opposite to the turntable 40. The food on the shelf 33 is heated.

The convection heater unit 20, which is another heating source, causes the convection heater 21 to generate heat at a high temperature by application of power, and blows air to the convection heater 21 by the convection fan assembly 22 to provide high temperature air. The food is heated by creating a flow and introducing it into the cavity 1.

On the other hand, the exhaust motor assembly 30 mounted on the upper cavity 1 serves to suck the smoke and heat rising from the lower cooker to exhaust to the outside.

However, the conventional microwave oven has the following problems.

When the food is placed on the shelf 33 and cooked, the high-temperature tropical air generated by the convection heater 20 does not flow smoothly under the cavity 1 by the food placed on the shelf 33. This causes food to be heated unevenly. For example, when the biscuits are cooked, a part of the food is heated too much, and a part of the biscuits is not heated enough to become raw.

In addition, as the length of the lead wires connecting the electric parts is increased by the length of the electric parts being mounted in the electric compartment 2 at a relatively long distance, the assembly time is increased.

In addition, the noise is increased by the relatively large number of fan assemblies during the operation of the microwave oven.

Accordingly, an object of the present invention is to solve the conventional problems as described above, the hood combined microwave oven to obtain a good cooking state by preventing the heating deviation of the food caused by the convection heater when cooking food placed on the shelf To provide.

Another object of the present invention is to provide a hood-use microwave oven, the cost is reduced and the assembly is improved by the length of the lead wire is shortened by mounting the electrical components in a relatively close distance.

Still another object of the present invention is to provide a hood-use microwave oven in which the number of fan assemblies is reduced and noise is reduced.

According to another feature of the present invention, the electrical component is a cavity which is a space where food is cooked, a side heater mounted on the side of the cavity to heat food in the cavity using convection heat, and the cavity in which the side heater is installed. Heat dissipated by an exhaust motor assembly mounted on the mounting surface and mounted on the mounting surface at a height close to the upper surface of the cavity corresponding to the other side of the cavity facing the one side of the, and installed on the upper side of the cavity It is comprised including an electric component, and the volume of the said cavity expands by the space formed under the said mounting surface.

The heater is further mounted on at least one side of the cavity upper and lower surfaces.

According to the present invention having such a configuration, it is possible to uniformly heat the food placed on the shelf and provides a cost saving and easy assembly process by a relatively simple installation structure.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to FIGS. 3 and 4.

As shown in the drawing, a cavity 101 in which food is cooked and an electrical equipment room 102 in which electrical components are mounted are formed in the microwave oven.

The convection heater 120 is mounted on the side surface T in the direction of the cavity 101 in the electric compartment 102. The convection heater 120 is a convection fan assembly that sends the ambient air heated by the convection heater 121 and the convection heater 121 into the cavity 101 by blowing air as described in the prior art ( 122).

The mounting surface 130 is installed at a height similar to the upper surface of the cavity 101 at the upper portion of the convection heater 120. The mounting surface 130 is mounted with electrical components including the magnetron 132, the high voltage transformer 134 and the high voltage capacitor 136, as shown in the plate shape.

On one side of the cavity 101, a stirrer pan assembly 140 is installed to uniformly irradiate microwaves generated by the electric component in the cavity 101, and a stirrer pan (140) inside the stirrer pan assembly 140. 141 is located.

The bottom surface of the cavity 101 is mounted with a circular turntable 145 so that food is rotated and heated while cooking, and a turntable motor 146 as a driving source is positioned below the turntable 145.

On the turntable 145, protrusions are formed on both sides of the cavity 101, and a shelf 150 is installed over the protrusions. The shelf is a rectangular frame having an area similar to the bottom surface of the cavity 101, the bar is coupled in a lattice form to form a plurality of rectangular through-holes.

On the other hand, the exhaust motor assembly having a function of cooling and cooling the electrical components located in the upper part of the electrical compartment 102 and suction and discharge the smoke and heat coming from the lower cooker

160 is installed from the upper portion of the cavity 101 to the rear side.

In addition to the configuration according to the embodiment of the present invention, the heater can be mounted on the upper or lower surface of the cavity 101, and the cooking time can be shortened by mounting the heater. In such a structure, it is preferable that the heater uses a radiant heat rather than a heater using convective heat.

When power is applied to the microwave oven having the above structure, a high voltage current is applied by the high voltage transformer 134 and the high voltage capacitor 136 installed on the upper mounting surface 130 of the electrical equipment room. The microwave is oscillated in the magnetron 132 by the high voltage and flows into the cavity 101. The microwaves introduced into the cavity 101 are uniformly irradiated into the cavity 101 by the rotation of the stirrer pan 141 installed in the stirrer pan assembly 140.

The convection heater 120 mounted on the side of the cavity 101 heats the ambient air while the convection heater 121 generates heat at a high temperature by applying power. The hot air is blown into the cavity 101 by the convection fan assembly 122 to form a tropical flow flowing inside the cavity 101.

Since the tropical stream is formed from the side of the shelf 150 mounted inside the cavity 101, it receives relatively little resistance of the food placed on the shelf 150 and the shelf 150, and passes through the upper and lower portions of the shelf 150. While flowing, it forms a tropical flow that circulates smoothly in the cavity 101. The food placed on the shelf 150 is heated evenly by the smooth flow of convective heat.

On the other hand, the surrounding air is sucked through the intake ports at both ends formed in the exhaust motor assembly 160 to be exhausted to the outside. In detail, one end of the intake port sucks smoke and heat from the cooker installed in the lower portion, and the intake port of the other end inhales air that radiates the electrical components. Air sucked in this way is exhausted to the outside of the microwave oven through the discharge port formed in the exhaust motor assembly 160 housing.

According to another exemplary embodiment of the present invention, the other side of the cavity 101 facing the one side (right side in FIG. 3) of the cavity 101 in which the convection heater 120 is installed (the left side in FIG. 3). Surface) is provided with a mounting surface 130 for mounting of the electric component. Therefore, the electric compartment 102 can be reduced to a minimum size for the installation of the convection heater 120, the volume of the cavity 101 is formed below the mounting surface 13 It can be enlarged. In addition, the volume of the cavity 101 is increased, and thus a large amount of food can be cooked.

In this structure, the heat dissipation of the electric component and the air flow flowing inside the microwave oven are formed by the blower fan assembly, and smooth tropical flow is generated by the convection heater 121 on the side surface. The volume of the cavity 101 is laterally expandable.

As described above, the convection pan assembly 122 is mounted on the side of the cavity 101 when the food is placed on a shelf, thereby forming a structure in which hot air smoothly circulates inside the cavity 101. As a result, the food placed on the shelf is uniformly heated, thereby improving cooking performance.

In addition, by the exhaust motor assembly 160, the structure for cooling the electrical components including the magnetron 132, the cooling fan assembly that is conventionally mounted to cool the electrical components is eliminated to achieve a structure of low cost and low noise.

In addition, the volume of the cavity 101 can be enlarged upward by the convection fan assembly 122 mounted on the side of the cavity 101, in which the electric component is moved to the upper part of the electrical compartment and mounted on the upper surface of the cavity 101. have. This enlargement of the cavity 101 allows the cooking of a large amount of food.

Finally, the length of the lead wire connecting the power terminal of the electric component is shorter than before due to the structure in which the electric components are mounted adjacent to each other on the mounting surface 130. In addition, the assembling time is shortened by the mounting structure which is relatively easy than before.

In the microwave oven according to the embodiment of the present invention, the electrical components are exhaust motor assembly.

It is mounted at a height similar to (160) is cooled by the exhaust motor assembly 160, the convection heater 120 is mounted on the side of the battlefield room by the tropical flow smoothly formed when cooking food on the shelf The technical subject is that food is heated uniformly.

Many other modifications based on the present invention will occur to those skilled in the art within the scope of the above.

According to the present invention as described above, by the convection heater installed on the side, even when cooking food on the shelf is formed a smooth tropical flow flowing inside the cavity has the effect that the food is uniformly heated.

In addition, the cooling fan assembly is eliminated by the structure of cooling the electrical components by the exhaust motor assembly, thereby achieving a cost reduction and low noise structure.

In addition, the electrical components are mounted on the upper part of the electric compartment and the convection fan assembly is mounted on the side of the electric compartment, thereby increasing the cavity volume upward.

In addition, the assembly time is shortened by the structure in which the electrical components are mounted relatively adjacent to the mounting surface, thereby reducing the cost by the length of the lead wire is shortened.
