The speaker <NUM> may communicate with the outside of the outer panel <NUM> through the first through hole 120c to effectively transmit or output an alarm and other voices to the user. Since a pair of speakers <NUM> are provided, a pair of first through holes 120c may also be provided and formed at a location corresponding to each of the pair of speakers <NUM>.

The second through hole 120d may be formed in a lower portion of one side of the outer panel <NUM> to pass through the outer panel <NUM>. A part of the button device <NUM> mounted inside the outer panel <NUM> through the second through hole 120d may be exposed to the outside of the outer panel <NUM>. The user may manipulate the button device <NUM> by contacting the exposed portion of the outer panel <NUM>.

The mounting guide 120e may be formed on the inner wall of the outer panel <NUM> to support the one or more or plurality of communication units <NUM>. Accordingly, the mounting guide 120e may be provided in the same number as the plurality of communication units <NUM>. The mounting guide 120e may guide or support the communication unit <NUM> to be mounted on the outer panel <NUM>.

For example, the mounting guide 120e may be provided so that a projection having a shape corresponding to the edge of the communication unit <NUM> is formed on the inner wall of the outer panel <NUM>. Each of the plurality of mounting guides 120e may be provided to have a shape and size corresponding to the shape and size of each of the plurality of communication units <NUM>.

For example, the fitting projection 120f may be disposed at a location adjacent to the edge of the plate-shaped control board <NUM>.

Accordingly, the control board <NUM> may have corners fitted into the fitting projections 120f and may be mounted on the outer panel <NUM>. A shape fitting structure corresponding to the shape of the control board <NUM> may be formed on the fitting projection 120f so that the corner of the control board <NUM> is fitted.

As shown in <FIG>, the first outlet <NUM> may be disposed on the upper portion of the outer panel <NUM>, and the second outlet <NUM> may be disposed on the lower portion of the outer panel <NUM>.

The first outlet <NUM> may be disposed on the upper portion of the outer panel <NUM>, and the air flowing or driven by the blowing device <NUM> may be discharged to the outside. The second outlet <NUM> may be disposed on the lower portion of the outer panel <NUM>, and the air flowing or driven by the blowing device <NUM> may be discharged to the outside.

Meanwhile, referring to <FIG>, when the door <NUM> is assembled, the first outlet <NUM> and the second outlet <NUM> may be partially blocked by the baffle <NUM> and the front cover <NUM>. At this time, holes for discharging air may be formed at locations corresponding to the first outlet <NUM> and the second outlet <NUM> in the baffle <NUM>.

The first outlet <NUM> may be provided at a location adjacent to an upper end of the display unit <NUM>, and the second outlet <NUM> may be provided at a location adjacent to a lower end of the display unit <NUM>. Accordingly, the air forcibly flowing inside the door <NUM> by the blowing device <NUM> may be discharged to the outside at locations adjacent to the upper and lower ends of the display unit <NUM> through the first outlet <NUM> and the second outlet <NUM>.

The air discharged through the first outlet <NUM> may form the air curtain on the upper portion of the door <NUM>. In addition, the air discharged through the second outlet <NUM> may form the air curtain on the lower portion of the door <NUM>.

The air curtain means a means for blocking the permeation of an external airflow into the door <NUM>. In the embodiment, a boundary surface or a boundary zone in which the flow of air discharged from the inside of the door <NUM> through the first outlet <NUM> and the second outlet <NUM> forms a boundary against the flow of the external air may be referred to as an air curtain.

The air curtain formed by the air discharged from the inside of the door <NUM> through the first outlet <NUM> and the second outlet <NUM> may suppress the permeation of external air into the door <NUM>.

Since the heating cooking device is disposed below the cooking appliance, the heat generated when the heating cooking device is used and the oil mist generated from the food being cooked may rise and permeate into the cooking appliance.

The heat transmitted from the heating cooking device to the cooking appliance may damage parts of the door <NUM> provided in the cooking appliance. In particular, parts in which the display unit <NUM> and circuits, elements, etc. related to its operation are embedded may be vulnerable to heat.

In addition, the oil mist transmitted from the food being cooked may be attached to the door <NUM> provided in the cooking appliance. The oil mist may be attached to the surface of the display unit <NUM> to lower the image quality of the display unit <NUM>, and attached to the surfaces of other parts mounted on the door <NUM> to damage these parts.

In the embodiment, the airflow discharged to the outside of the door <NUM> through the first outlet <NUM> and the second outlet <NUM> provided in the door <NUM> forms the air curtain, so that the heat and oil mist rising from the heating cooking device disposed below the cooking appliance can be effectively blocked by the air curtain.

Accordingly, it is possible to effectively suppress various electronic parts including the display unit <NUM> provided in the door <NUM> from being damaged or degraded by the heat and the oil mist.

Referring to <FIG>, the air guide <NUM> may include an inlet <NUM> and a mounting hole <NUM>. The inlet <NUM> may be disposed on an upper portion of the air guide <NUM>, external air may be introduced through the inlet <NUM>, and at least one inlet <NUM> may be provided.

The inlet <NUM> may be disposed at a location corresponding to the first aperture <NUM> provided on the upper portion of the outer panel <NUM>. Accordingly, the external air may pass through the first aperture <NUM> of the outer panel <NUM> to flow into the door <NUM> through the inlet <NUM>. AS shown in <FIG> there are two inlets <NUM> each one a side of the blowing device <NUM>. The air enters the one or more inlets <NUM> from above is vertically introduced into the air guide <NUM>.

The mounting hole <NUM> may be formed at a lower portion of the inlet <NUM> in the air guide <NUM>, and the blowing device <NUM> may be mounted therein. The mounting hole <NUM> may be formed to pass through the air guide <NUM> in the front-rear direction of the door <NUM>.

Accordingly, air may flow from the upper portion to the lower portion of the air guide <NUM> through the inlet <NUM>, and then its direction may be changed, so that the air may flow from the rear to the front of the air guide <NUM> through the mounting hole <NUM> in direction of the hollow space <NUM> of the outer panel <NUM>.

The blowing device <NUM> may include a casing <NUM> and the blowing fan <NUM>. The casing <NUM> may be disposed in the mounting hole <NUM> and formed with a hollow or opening, and the blowing fan <NUM> may be mounted in the hollow or opening.

The blowing fan <NUM> may be rotatably mounted in the casing <NUM>, and may flow air from the rear to the front of the air guide <NUM>. The blowing fan <NUM> may receive electricity and rotate to flow air inside the door <NUM>.

By the rotation of the blowing fan <NUM>, external air may flow into the door <NUM> through the one or more inlets <NUM>, and may be discharged to the outside of the door <NUM> through the first outlet <NUM> and the second outlet <NUM>. The mounting hole <NUM> of the air guide <NUM> may be formed in the middle of the casing <NUM> and formed to correspond to the location, area, and shape of the hollow in which the blowing fan <NUM> is disposed.

Hereinafter, the airflow inside the door <NUM> will be described in detail with reference to <FIG>. In <FIG>, the airflow is indicated by arrows.

As the blowing fan <NUM> rotates, external air may flow into the door <NUM> through the on or more inlets <NUM> of the air guide <NUM>, and flow to be discharged to the outside of the door <NUM> through the first outlet <NUM> and the second outlet <NUM>.

The air forcibly flowing by the blowing fan <NUM> may specifically have the following flow path of the airflow.

The air may flow into the door <NUM> from the first aperture <NUM> of the outer panel <NUM> and the inlet <NUM> provided at a location corresponding thereto. The air flowing into the door <NUM> may flow downward from the door <NUM> to flow into the blowing fan <NUM>.

The air may pass through the blowing fan <NUM> in the front-rear direction of the door <NUM>. At this time, the air may pass through the mounting hole <NUM> of the air guide <NUM> while passing through the blowing fan <NUM>. The flow direction of the air in the blowing fan <NUM> may be changed from the up-down direction of the door <NUM> to the front-rear direction thereof.

Since the front of the mounting hole <NUM> is blocked by the display unit <NUM>, the air passing through the mounting hole <NUM> may be branched in the up-down direction in front of the air guide <NUM>.

A part of the branched air may flow upward from the door <NUM> and may be discharged through the first outlet <NUM>. The other part of the branched air may flow downward from the door <NUM> and may be discharged through the second outlet <NUM>.

The air branched from the first outlet <NUM> and the second outlet <NUM> may surround the entire door <NUM>. In particular, the branched air may surround the front surface of the door <NUM>. This structure can allow the air discharged from the first outlet <NUM> and the second outlet <NUM> to form the air curtain on the door <NUM>, thereby effectively suppressing the heat and oil mist generated from the heating cooking device disposed below the cooking appliance from permeating into the door <NUM>.

Meanwhile, at least a part of the air discharged from the first outlet <NUM> may come into contact with the front surface of the display unit <NUM> while moving downward by gravity to cool the display unit <NUM>.

In addition, the above-described airflow structure inside the door <NUM> may allow the air flowing into the door <NUM> to flow through the entire inside of the door <NUM>. For example, the air may flow in the entire space formed by the rear surface of the display unit <NUM> and the outer panel <NUM>.

Accordingly, the air flowing inside the door <NUM> may cool the entire rear surface of the display unit <NUM>, and effectively cool the outer panel <NUM> and other parts mounted on other portions of the door <NUM>.

In particular, the outer panel <NUM> may be provided with parts that generate heat, such as the speaker <NUM>, the microphone <NUM>, the communication unit <NUM>, and the control board <NUM>. These heat-generating parts may be disposed over the entire outer panel <NUM>. Accordingly, the air may flow through the entire inside of the outer panel <NUM>, thereby effectively cooling these heat-generating parts.

As shown in <FIG>, the first aperture <NUM> and the inlet <NUM> into which air flows may communicate with each other. As the blowing fan <NUM> rotates, the external air may flow into the air guide <NUM> through the first aperture <NUM> and the inlet <NUM> to flow toward the blowing device <NUM> through the space formed by the inner panel <NUM> and the air guide <NUM>.

The air may flow toward the blowing fan <NUM> of the blowing device <NUM> in the space formed by the shielding plate <NUM>. The air may pass through the blowing fan <NUM> and collide with the rear surface of the display unit <NUM> disposed to face the blowing fan <NUM> to cool the display unit <NUM>.

After the air passing through the blowing fan <NUM> collides with the rear surface of the display unit <NUM>, the flow may be branched in the upward and downward direction of the display unit <NUM>. The air directed to the upper side of the display unit <NUM> may be discharged to the outside of the door <NUM> through the first outlet <NUM> provided on the upper portion of the outer panel <NUM>. The air flowing downward from the display unit <NUM> may be discharged to the outside of the door <NUM> through the second outlet <NUM> provided on the lower portion of the outer panel <NUM>.

In the embodiment, the air flowing inside the door <NUM> can cool the entire front surface of the display unit <NUM> while being discharged through the first outlet <NUM>. In addition, the air flowing inside the door <NUM> can effectively cool the heat-generating parts mounted on the rear surface of the display unit <NUM> and inside the door <NUM>.

<FIG> is an exploded perspective view of <FIG>. <FIG> is a view of <FIG> from another direction.

Referring to <FIG>, the mounting hole <NUM> may be formed in the middle of the air guide <NUM>. The casing <NUM> has a hollow having a location, size, and shape corresponding to the mounting hole <NUM>, and the blowing fan <NUM> may be disposed in the hollow. The casing <NUM> may be disposed at a location corresponding to the hollow and the mounting hole <NUM> of the air guide <NUM> and mounted on one surface of the air guide <NUM>.

A hollow 130a may be formed in the inner panel <NUM>. Since the hollow 130a of the inner panel <NUM> is blocked by the shielding plate <NUM>, the air introduced through the inlet <NUM> may not leak into the hollow 130a of the inner panel <NUM>. Accordingly, the inner panel <NUM> and the shielding plate <NUM> together may form a flow path of the air through which the air cooling the inside of the door <NUM> flows.

The air guide <NUM> may include an upper portion 140a in which the inlet <NUM> is formed and a lower portion 140b in which the blowing device <NUM> is disposed. When the air guide <NUM> and the inner panel <NUM> are coupled, the lower portion 140b may be generally disposed at a location corresponding to the hollow 130a of the inner panel <NUM>.

When looking down at the air guide <NUM> from the upper portion of the door <NUM>, a cross-sectional area of the upper portion 140a of the air guide <NUM> may be formed to be greater than a cross-sectional area of the lower portion 140b. As the cross-sectional area of the upper portion 140a is expanded, the cross-sectional area of the inlet <NUM> may also be expanded. Accordingly, in the air guide <NUM>, as the inlet <NUM> through which air is introduced is expanded, external air may be easily introduced into the air guide <NUM>.

Meanwhile, the lower portion 140b of the air guide <NUM> has a smaller cross-sectional area than that of the upper portion 140a, but since the lower portion 140b of the air guide <NUM> corresponds to the hollow 130a of the inner panel <NUM>, the airflow space in the portion corresponding to the lower portion 140b may be expanded toward the shielding plate <NUM> by the hollow 130a of the inner panel <NUM>. As a result, the lower portion 140b of the air guide <NUM> may also have a shape in which the airflow space is expanded by the hollow 130a of the inner panel <NUM>.

In other words, the lower portion 140b of the air guide <NUM> corresponding to the hollow 130a of the inner panel <NUM> is formed to have a smaller cross-sectional area than that of the upper portion 140a of the air guide <NUM>, but the flow space of the lower portion 140b of the air guide <NUM> may be expanded to the shielding plate <NUM> by the hollow 130a of the inner panel <NUM>.

Accordingly, the upper portion 140a and the lower portion 140b of the air guide <NUM> may have the shape of an expanded cross-sectional area due to the above-described structure. Accordingly, the airflow space formed by coupling the air guide <NUM> and the inner panel <NUM> in the structure in which the air guide <NUM> and the inner panel <NUM> are coupled may be sufficiently wide, and the air may be smoothly introduced from the outside and may also smoothly pass through the blowing device <NUM> mounted on the lower portion 140b of the inner panel <NUM>.

In addition, due to the decrease in the cross-sectional area of the lower portion 140b of the air guide <NUM>, conversely, the space in which the air passing through the blowing device <NUM> is discharged from the lower portion 140b of the air guide <NUM> may be expanded. At this time, the air passing through the blowing device <NUM> may pass through the hollow <NUM> of the outer panel <NUM> and come into contact with the display unit <NUM> to cool the display unit <NUM>.

The above-described structure allows the door <NUM> to have a slim overall structure and increases the flow rate of air flowing therein, thereby improving the cooling efficiency of the door.

<FIG> is a rear view of the door <NUM> of one embodiment. <FIG> is an enlarged view of a part of <FIG> is a front view of the shielding plate <NUM> in the state in which the third camera <NUM> is mounted.

The bracket <NUM> may have an opening <NUM> opened in a direction toward the cavity <NUM> when the door <NUM> is closed. The bracket <NUM> may have a three-dimensional shape to adjust the gaze direction of the third camera <NUM>. In other words, the bracket <NUM> may be formed by recessing one side surface of the shielding plate <NUM> when viewing the bracket <NUM> from the cavity <NUM>.

The window <NUM> may be disposed behind the bracket <NUM>, that is, at a location facing the cavity <NUM> when viewed from the bracket <NUM>, and mounted in the opening <NUM> of the bracket <NUM>.

Hereinafter, when the door <NUM> is closed, the rear or rear surface may refer to a location, a surface, or a direction that views the cavity <NUM> when viewed from the door <NUM>.

The window <NUM> can close the opening <NUM> of the bracket <NUM> to block the inflow of heat and oil mist transferred from the cavity <NUM> into the bracket <NUM>, thereby protecting the third camera <NUM> mounted on the bracket <NUM>.

The window <NUM> may be made of a transparent material so that the third camera <NUM> may capture the inside of the cavity <NUM> through the window <NUM>. In addition, the window <NUM> may be made of a material having high heat resistance. For example, the window <NUM> may be made of a quartz material. However, the present invention is not limited thereto.

The sealing member <NUM> may be provided to seal a gap between the opening <NUM> and the window <NUM>. The sealing member <NUM> may be provided to surround the window <NUM> at an edge of the opening <NUM>, and attached to the bracket <NUM> and/or the window <NUM>.

Accordingly, the sealing member <NUM> may be provided in a closed curve shape having a predetermined width. The sealing member <NUM> may be made of, for example, a silicone resin material having high heat resistance. However, the present invention is not limited thereto.

Referring to <FIG>, the window <NUM> may include a capturing region <NUM> and a masking region <NUM>.
