Description

Cooking Appliance{COOKING APPLIANCE}

The present invention relates to a cooking appliance, and more specifically, to a cooking appliance that provides both a cooking function and a hood function.

A cooking appliance is a type of home appliance for cooking food and is installed in a kitchen space to cook food according to the user's intention. These cooking appliances can be classified in various ways depending on the heat source or type used and the type of fuel.

Cooking appliances can be classified into open and closed cooking appliances depending on the type of space where food is placed. Closed cooking appliances include ovens and microwaves, while open cooking appliances include cooktops and hobs.

A closed cooking appliance is a cooking appliance that shields the space where food is located and cooks the food by heating the shielded space. In a closed cooking appliance, a chamber, or cooking room, which is a space where food is placed and shielded when food is to be cooked, is provided inside the main body. This galley is actually a space where food is cooked. A heat source is provided in the interior or exterior space of the galley to heat the galley.

Among closed cooking appliances, a microwave oven is a cooking device that generates microwaves using electricity, penetrates the cooking objects contained within the cooking chamber, and heats the cooking objects by causing molecular movement within them.

A microwave oven is a kitchen appliance that simultaneously heats the inside and outside of food by radiating high frequency waves from a magnetron to the food. It has high thermal efficiency, drastically shortening the cooking time of food, and reducing the loss of nutritional value during the cooking, thawing, and warming process. It is widely used due to its advantages such as being able to cook food directly while storing it in a container.

Recently, hood-type microwave ovens equipped with a hood function, also known as OTR (Over the range) type microwave ovens, have been released. A microwave oven with a hood function has a hood function that discharges air containing foreign substances (hereinafter referred to as 'cooking gas') generated during the process of cooking food in the cooking appliance installed below it to the outside or discharges it into the room after filtration. has

This hood/microwave oven is equipped with a fan for sucking and discharging air. These pans are typically placed on the upper side of the cavity forming the galley. That is, in a microwave oven with a hood, the fan is generally placed higher than the cavity.

However, when the fan is placed in the above position, the distance between the fan and the suction inlet located at the bottom of the hood/microwave oven becomes greater than the vertical length of the cavity. As the distance between the intake inlet and the fan increases, the cooking gas collection performance of the hood/microwave oven inevitably decreases. This is because the flow rate of the intake airflow generated by the fan can be reduced in inverse proportion to the square of the distance from the fan.

Additionally, if the fan is placed in the above position, the length of the entire microwave oven with hood in the vertical direction will inevitably increase. As the vertical length of the hood microwave oven increases, the possibility that the hood microwave oven protrudes further downward than the upper cabinet increases when the hood microwave oven is installed in the upper cabinet.

If the hood/microwave oven protrudes further downward than the upper cabinet, not only does it not look good, but the gap between the cooktop installed at the bottom of the upper cabinet and the hood/microwave oven may narrow, which may cause problems.

If the distance between the cooktop and the hood microwave oven narrows as the hood microwave oven protrudes to the bottom of the upper cabinet, problems may arise where the hood microwave oven blocks the view of the user using the cooktop and the cooking area of the cooktop becomes narrower. You can.

The present invention provides a cooking appliance with an improved structure so as to provide a hood function while suppressing an increase in the vertical length of the entire cooking appliance.

Hereinafter, among the first fan assembly 110 and the second fan assembly 120, the one disposed in the rear space 10d will be referred to as the first blower, and the one disposed in the side space 10c will be referred to as the second blower. Do this.

In this embodiment, the first blowing part includes the first fan assembly 110, and the second blowing part includes the second fan assembly 120.

In the cooking appliance of this embodiment, both the first exhaust port 103 and the first fan assembly 110 are disposed in the rear space 10d, and the first exhaust port 103 and the first fan are disposed on the rear space 10d. The assembly 110 may be arranged in a vertical direction.

Meanwhile, the rear plate 15 of this embodiment may be provided with a rear protruding surface 15a. The rear protruding surface 15a may form a surface that protrudes further rearward than the remaining area of the rear plate 15 excluding the rear protruding surface 15a.

For example, the rear plate 15 may form a plane perpendicular to the front-rear axis. In addition, the rear protruding surface 15a forms a plane parallel to the rear plate 15, and may be disposed in a position that protrudes further rearward than the remaining area of the rear plate 15 excluding the rear protruding surface 15a.
