[0072] The cooking appliance 1 can be provided with an electrical component compartment 50 accommodating electrical components (not shown) configured to control the operation of various accessories including the display module 40. The electrical component compartment 50 can be disposed above the cooking chamber 20, and an insulation material (not shown) insulating the electrical component compartment 50 and the cooking chamber 20 can be disposed between the electrical component compartment 50 and the cooking chamber 20 to prevent heat of the cooking chamber 20 from being transferred to the electrical component compartment 50. In addition to being arranged between the electrical component compartment 50 and the cooking chamber 20, the insulation material can be disposed to completely cover the outside of the cooking chamber 20 to prevent heat of the cooking chamber 20 from being transferred to the outside of the cooking appliance 1.

[0073] Because the temperature within the electrical component compartment 50 increases due to heat of various electrical components, the cooking appliance 1 can include a blower 90 configured to circulate air in the electrical component compartment 50 to cool the electrical component compartment 50 and a driving motor 51 configured to drive the blower 90. The blower 90 and the driving motor 51 can be located within the electrical component compartment 50.

[0074] The cooking appliance 1 can include a flow path 110 that not only cools the inside of the electrical component compartment 50 but also cools high-temperature air passing through the door flow path 32 and then discharges the cooled air to the front side of the cabinet 10.

[0075] The flow path 110 can include an intake flow path 111 that intakes air passing through the door flow path 32 and then being discharged to the outside of the door 30 through the door outlet 38a and a discharge flow path 112 that discharges air introduced to the blower 90 through the intake flow path 111 to the front side of the cabinet 10. This will be described in detail below.

[0076] According to the present disclosure, the cooking appliance 1 can include a circulation flow path 113 that guides air from one side of the discharge flow path 112 to the upper side of the blower 90. The circulation flow path 113 will be described later.

[0077] Reference Figures 1 to 3A gap can be provided between the upper end of the cabinet 10 and the door 30. In particular, one or more gaps can be provided between the lower end of the control panel 17 and the upper end of the door 30.

[0078] The gap can include a first region 10a and a second region 10b. The first region 10a is also referred to herein as an air outlet 10a. The second region 10b can indicate a region other than the first region 10a.

[0079] According to one embodiment of the disclosure, the height g2 of the first region 10a and the height g1 of the second region 10b can be equal to each other. In other words, the sizes of the first region 10a and the second region 10b formed between the lower end of the control panel 17 and the upper end of the door 30 can be uniformly provided along the lateral sides.

[0080] According to one embodiment of the disclosure, the heights of the first region 10a and the second region 10b can be 8 mm or less. In particular, the heights of the first region 10a and the second region 10b can be 4 mm to 8 mm. In one embodiment of the disclosure, the first region 10a and the second region 10b can be 4 mm.

[0081] According to the disclosure, the height of the air outlet 10a can be less than the height of the air outlet in a conventional cooking appliance. Since the height of the air outlet 10a is reduced, the flow resistance of the air outlet 10a and its vicinity can increase, and thus the amount of air discharged to the front side of the cabinet 10 through the air outlet 10a can significantly decrease. In addition, air passing through the door flow path 32 can not flow into the blower 90, but air can flow from the blower 90 to the door flow path 32. Air passing through the door flow path 32 can not be smoothly discharged to the front side of the cabinet 10, and the surface temperature of the door 30 can increase. When the surface temperature of the door 30 is greater than or equal to a predetermined temperature, safety regulations cannot be satisfied.

[0082] According to the disclosure, an improved aesthetic appearance of the cooking appliance can be provided by reducing the size of the air outlet 10a. The size of the air outlet 10a can particularly indicate the height of the air outlet 10a. A cooking appliance capable of preventing an increase in the surface temperature of the door 30 while reducing the size of the air outlet 10a can be provided. In addition, the cooking appliance can prevent an increase in flow resistance and a decrease in air volume due to the reduction in the size of the air outlet 10a.

[0083] Figure 5 is Figure 4 a magnified view of a portion of

[0084] Hereinafter, air flow in a cooking appliance according to one embodiment of the disclosure will be described in detail with reference to Figure 5 the accompanying drawings.

[0085] Referring to Figure 5 , the air introduced into the door inlet 39 (refer to Figure 4 ) can move upward along the door flow path 32 and can be discharged to the outside of the door 30 through the door outlet 38a.

[0086] The front panel 11 can be provided with an air inlet 11a disposed to face the door outlet 38a. The air discharged to the outside of the door 30 through the door outlet 38a can be introduced into the entry flow path 110 through the air inlet 11a. The air on the entry flow path 110 can be introduced into the blower 90 by the blower 90 configured to draw air in the opposite direction. The air moving along the entry flow path 110 can be introduced into the blower 90 through the duct hole 82a provided below the blower 90.

[0087] The blower 90 can be configured to draw air in the opposite direction. The blower 90 can draw air from the upper side of the blower 90 while drawing air from the lower side of the blower 90. Accordingly, the air moving along the entry flow path 110 can be drawn into the blower 90 from the lower side of the blower 90, and the air inside the electrical component compartment 50 can be drawn into the blower 90 from the upper side of the blower 90.

[0088] The air drawn into the blower 90 can be discharged to the lateral side of the blower 90. The air discharged by the blower 90 can move along the discharge flow path 112. The discharge flow path 112 can be located above the entry flow path 111. The discharge flow path 112 can extend from the blower 90 to the air outlet 10a. The discharge flow path 112 can be disposed such that the height of the discharge flow path 112 gradually decreases from the blower 90 toward the air outlet 10a.

[0089] As described above, according to the present disclosure, the height of the air outlet 10a is less than the height of the air outlet compared to the conventional method, and the height of the discharge flow path 112 gradually decreases toward the air outlet 10a. As the height of the air outlet 10a decreases, the flow resistance in the discharge flow path 112 adjacent to the air outlet 10a can increase, and the air volume can decrease. In order to prevent an increase in the surface temperature of the door 30 caused by the increase in flow resistance and the decrease in air volume, the cooking appliance 1 according to the present disclosure can include a circulation flow path 113.

[0090] The circulation flow path 113 can connect one side of the discharge flow path 112 adjacent to the air outlet 10a to the upper portion of the blower 90. One end of the circulation flow path 113 can be connected to the upper surface of the discharge flow path 112, and the other end of the circulation flow path 113 can be connected to the upper side of the blower 90. When the circulation flow path 113 is provided, a portion of the air on the outlet side of the discharge flow path 112, which has an increased flow path resistance, is reintroduced into the blower 90 through the circulation flow path 113. Accordingly, the flow resistance on the outlet side of the discharge flow path 112 can be reduced, and the remaining air on the outlet side of the discharge flow path 112 can be discharged to the front of the cabinet 10 through the air outlet 10a.

[0091] In summary, the air passing through the door flow path 32 can flow into the discharge flow path 112 through the intake flow path 111 and the blower 90, a portion of the air can be reintroduced into the blower 90 through the circulation flow path 113, and the remaining air can be discharged to the front of the cabinet 10 through the air outlet 10a. That is, the air introduced through the door inlet 39 can be smoothly discharged through the air outlet 10a, and the air in the door flow path 32 can be smoothly moved. When the air moves through the door flow path 32, the door 30 can be cooled, and an increase in the surface temperature of the door 30 can be prevented.

[0092]

[0093] According to one embodiment of the disclosure, the duct inlet 101 can be disposed in front of the air inlet 11a. This is because the air inlet 11a is disposed in the front panel 11, and the discharge flow path 112 has a very small height in front of the front panel 11, so the flow resistance increases in front of the front panel 11. Accordingly, in order to allow the circulation flow path 113 to operate more effectively, the duct inlet 101 can be located in front of the air inlet 11a.

[0094] The guide duct 12 can be disposed on the outlet side of the discharge flow path 112. The guide duct 12 can be integrally formed with the second duct 82, which will be described later, or can be formed separately from the second duct 82. The guide duct 12 can be provided to prevent the air moving along the discharge flow path 112 from moving to the door outlet 38a of the door 30. The guide duct 12 can be disposed to cover the upper surface of the door 30.
