It is configured to include.

According to another aspect, a built-in cooker includes: first and second flow paths through which suctioned indoor air flows; A cooling chamber into which some air divided in the first flow path and air on the second flow path are introduced; A discharge passage through which air on the cooling chamber is discharged to the outside; A control element located in the cooling chamber; A heater operated by control of the control element; A cavity accommodating food heated by the heater; A barrier in which a through hole is formed to provide a passage through which a portion of air on the first flow path moves to the cooling chamber; And an outer case having a suction hole for providing a passage through which a portion of air on the second flow path moves to the cooling chamber. It is configured to include.

According to the proposed embodiment, there is an advantage that the heat generated in the upper heater by the barrier can be prevented from moving to the control element.

In addition, as the air flow path (first flow path) is formed below the barrier, the heat of the upper heater may be effectively blocked from moving to the control element by the air flowing through the first flow path.

In addition, suction holes and through holes for passing air through the upper wall of the outer case and the barrier are formed, and the air passing through the suction holes and the through holes is moved to the control element side, thereby effectively cooling the control element. It can be done.

Hereinafter, an embodiment will be described with reference to the drawings.

1 and 2, the built-in cooker 1 according to the present embodiment is accommodated in a cabinet 5 installed in a kitchen. The cabinet 5 has an open front, and the cooker 1 is introduced into the cabinet 5 through the opened portion.

In the cooking apparatus 1, an outer case 60, a cavity 10 provided inside the outer case 60, forming a cooking chamber 11, and foods accommodated in the cooking chamber 12 are heated. A heating source, a door 16 for opening and closing the cooking chamber 11, an insulator 40 surrounding the outside of the cavity 10, and a side of the cavity 10, the cooking apparatus ( A control panel 50 for controlling 1) is included.

In detail, the bottom wall 61b of the outer case 60 is seated on the bottom surface of the cabinet 5. Of course, the bottom wall 61b of the outer case 60 may be supported by a bracket provided on the bottom of the cabinet 5.

The cavity 10 is formed in a box shape with an open front surface. The heating source includes an upper heater 21 provided above the cavity 10 and a lower heater 22 provided below the cavity 10. The upper heater 21 and the lower heater 22 radiantly heats the food accommodated in the cooking chamber 11 to allow cooking to be performed.

On the outside of the cavity rear wall 15, a convection device 30 is provided to convection heated air to allow cooking of the food. The convection device 30 includes a convection heater 33, a convection fan 32 and a convection motor 31. Since the structure of the convection device is the same as the conventional structure, a detailed description thereof will be omitted.

The insulator 40 primarily blocks the heat generated from the cavity 10 from being transferred to the outside.

In addition, the insulator 40 and the outer case 60 are spaced apart at a predetermined interval. Thus, a space 86 is formed between the insulator 40 and the outer case 60. Cooling air flows through the space 86.

The control panel 50 includes an operation knob 55, a plurality of operation buttons 53, a display unit 54 for displaying the operation state of the cooking appliance 1, and the like. Control elements 51 are provided. The control element 51 may be, for example, a PCB.

Meanwhile, a first suction port 81 is formed between the control panel 50 and the door 16 to allow air to be sucked in.

In addition, when the cooking appliance 1 is accommodated in the cabinet 5, a predetermined space is formed between the control panel 50 and the cabinet 5, and the space is a second suction port for allowing indoor air to be sucked in. (81a in FIG. 1) is defined.

Therefore, indoor air flows into the inner space of the outer case 60 through the respective suction ports 81 and 81a.

In addition, when the cooking appliance 1 is accommodated in the cabinet 5, a predetermined space is formed between the lower side of the door 16 and the bottom of the cabinet 5, and the space is an outlet for discharging air ( 83).

In addition, a blowing fan 70 is provided in the space 86 between the insulator 40 and the outer case 60 to allow air to flow in the space 86. The blowing fan 70 may be installed above the insulator 40.

On the other hand, a spaced upper side of the insulator 40 is provided with a barrier 90 to block the heat generated by the upper heater 21 from moving to the control element 51. The barrier 90 is located between the control element 51 and the cavity 10.

A cooling chamber 88 through which the control element is cooled is formed between the barrier 90 and the upper wall 61a of the outer case 60.

In addition, a first flow path 85 through which the air sucked through the first suction port 81 flows is formed between the barrier 90 and the insulator 40. That is, the barrier 90 defines an upper surface of the first flow path 85.

The barrier 90 includes a first portion 91 extending in a rearward direction from the control panel 50 side and a second portion 93 inclined downward from the first portion 91 to the rear side. ) Is included. The first portion 91 is formed with a through hole 92 for allowing a portion of the air on the first flow path 85 to move to the cooling chamber 88. At the side of the cooling chamber 88, the through hole 92 serves as a suction hole through which air is sucked. Thus, the barrier 90 allows air on the first flow path 85 to flow in a divided manner.

The second portion 93 allows the flow resistance of the air flowing through the first flow path 85 to increase so that the air on the first flow path 85 passes through the through hole 92. To move smoothly.

On the other hand, the upper wall (61a) of the outer case is spaced apart from the upper wall of the cabinet (5) by a predetermined interval. Accordingly, a second flow path 84 for suctioning the indoor air into the cooking appliance 1 is formed between the upper wall 61a of the outer case and the upper wall of the cabinet 5.

The upper wall 61a of the outer case has a first portion 62 adjacent to the upper wall of the cabinet 5 and extending in the front-rear direction, and a second portion 63 extending downward from the first portion 62. ) And a third portion 65 extending obliquely from the second portion 63 to the rear side. That is, the upper wall 61a of the outer case 5 is formed stepped.

In addition, a suction hole 64 is formed in the second part 63 to allow air on the second flow path 84 to flow into the outer case 5.

In this case, the suction hole 64 is formed in the second portion 63 because water is introduced from the outside when water flows between the upper wall of the outer case 60 and the upper wall of the cabinet 5. This is to prevent water from flowing into the outer case 60.

In addition, the second portion 63 is spaced apart from the rear surface of the control element 51 by a predetermined interval. Here, the direction of the surface of the control element 51 will be described, wherein the front surface of the cooking appliance is the front surface of the control element 51, and the rear surface refers to the opposite surface.

Therefore, in this embodiment, the air sucked through the suction hole 64 is moved toward the control element 51 at the rear side of the control element 51.

On the other hand, a discharge passage 87 is formed between the insulator 40 and the bottom wall 61b of the outer case 60.

Hereinafter, the air flow in the built-in cooking apparatus will be described.

3 is a view showing the flow of cooling air in the built-in cooker.

Referring to FIG. 3, when the cooking appliance is turned on and the start button is selected, the cooking appliance 1 is operated by the control of the control element 51. Then, the blowing fan 70 is operated.

When the blower fan 70 is operated, indoor air flows into the first flow path 85 through the first suction port 81 and into the second flow path 84 through the second suction port 81a. .

The air introduced into the first flow path 85 is moved to the cooling chamber 95 through the through hole 92. Air moved to the cooling chamber 88 through the through hole 92 cools the lower side of the control element 51.

In addition, the air introduced into the second flow path 84 is introduced into the outer case 60, more specifically, into the cooling chamber 88 through the suction hole 63. Air introduced into the cooling chamber 88 through the suction hole 64 cools the upper portion of the control element 51.

That is, in this embodiment, air is introduced into the cooling chamber 88 from above and below the control element 51 so that the control element 51 is cooled.

The air moved to the cooling chamber 88 through the suction hole 64 and the through hole 92 moves to the space 86 after cooling the control element 51 in the cooling chamber 88. And merges with the air of the first flow path 85.

The combined air passes through the space between the rear wall of the insulator 40 and the rear wall of the outer case 60 and the discharge passage 87 after passing through the blower fan 70, and finally the discharge port 83. Through the room).

According to this embodiment, there is an advantage that the heat generated in the upper heater 21 by the barrier 90 can be blocked from moving to the control element 51.

In addition, as an air flow path (first flow path) is formed below the barrier 90, the heat of the upper heater 21 is transferred to the control element 51 by air flowing through the first flow path 85. Movement can be effectively blocked.

In addition, a suction hole 64 and a through hole 92 through which air passes through the upper wall of the outer case 5 and the barrier 90 are formed, and the suction hole 64 and the through hole 92 are formed. Since the air that has passed is moved to the control element 51 side, effective cooling of the control element 51 can be achieved.
