The room air outlet 113 is formed by cutting a part of an upper end of the front surface of the cavity 110 corresponding to the upper part of the cooking chamber 111.

A base plate 120 is coupled to a lower portion of the cavity 110 corresponding to the lower portion of the cooking chamber 111. The base plate 120 substantially forms the bottom surface of the microwave oven 100. The upper surface of the base plate 120 is positioned apart from the bottom surface of the cavity 110. Hereinafter, a space between the bottom surface of the cavity 110 and the upper surface of the base plate 120 is referred to as an intake passage Pi.

An air inlet 121 is formed in the base plate 120. The intake port 121 is formed by cutting a part of the bottom surface of the base plate 120. The air intake port 121 is provided at a lower portion of the microwave oven 100, for example, in a gas oven range or an electric oven range, and sucks air containing contaminants generated during the cooking process . A filter 123 is installed on the intake port 121. The filter 123 serves to remove pollutants contained in the air sucked through the suction port 121, for example, oil.

A back plate 130 is coupled to a rear end of the cavity 110. The back plate 130 substantially forms the rear surface of the microwave oven 100. At this time, the back plate 130 is positioned so that its front surface is spaced apart from the rear surface of the cavity 110. Hereinafter, a space between the rear surface of the cavity 110 and the front surface of the back plate 130 is referred to as a first exhaust passage Po1. Therefore, the lower end of the first exhaust passage Po1 communicates with the rear end of the intake passage Pi.

The outer casing 140 is coupled to the cavity 110, the base plate 120, and the back plate 130. The outer casing 140 forms an upper surface and both side surfaces of the microwave oven 100. Meanwhile, the upper surface of the outer casing 140 is separated from the upper surface of the cavity 110 by a predetermined distance.

An outdoor air outlet 141 is formed on an upper surface of the out casing 140 forming an upper surface of the microwave oven 100. The outdoor exhaust 141 is positioned substantially in the upper right chamber of the first exhaust passage Po1. The size and position of the outdoor exhaust 141 are defined by the standard. The outdoor exhaust 141 is substantially equally divided by an imaginary straight line bisecting the upper surface of the microwave oven 100 and has a smaller size than the cross section of the first exhaust passage Po1. Substantially, the outdoor air outlet 141 can communicate with a hood (not shown).

The microwave oven 100 is provided with a plurality of exhaust fan assemblies. The exhaust fan assembly sucks air containing pollutants into the interior of the microwave oven 100 through the intake port 121 and sucks the sucked air through the indoor exhaust port 113 or the outdoor exhaust port 141. [ To the indoor or outdoor. In this embodiment, the exhaust fan assemblies 150 and 160 are two. 3 and 4, the left exhaust fan assembly 150 is referred to as a first exhaust fan assembly 150 and the right exhaust fan assembly 160 is referred to as a second exhaust fan assembly 150. [ 160 ").

The first and second exhaust fan assemblies 160 respectively include one exhaust motor 151 and one exhaust fan 153, and 155, 163 and 165, respectively. The exhaust motors 151 and 161 substantially provide a driving force for rotation of the exhaust fans 153, 155, 163 and 165. The exhaust fans 153, 155, 163 and 165 are coupled to both sides of the exhaust motors 151 and 161. The first and second exhaust fan assemblies 160 are disposed at a position defined by a rear end of the base plate 120 and a lower end of the back plate 130, 153, 155, 163, and 165 are adjacent to each other. 3 and 4 of the exhaust fan 153 (155) of the first exhaust fan assembly 150 will be referred to as the first exhaust fan 153, 3 and 4 of the exhaust fan 153 (155) of the first exhaust fan assembly 150 to the first exhaust fan 155, the second exhaust fan assembly 155, The exhaust fan 163 on the right side of the drawing in Figs. 3 and 4 among the exhaust fans 163 and 165 of the first exhaust fan assembly 160 is referred to as a second exhaust exhaust fan 163 and the exhaust fan 163 of the second exhaust fan assembly 160 (163) and (165), the exhaust fan 165 on the left side in FIG. 3 and FIG. 4 is called a second inner exhaust fan 165. Accordingly, the first and second outer exhaust fans 153 and 163 are positioned relatively farther from the outdoor exhaust 141 than the first and second inner exhaust fans 155 and 165, do.

Further, a partition member 170 is provided above the first and second exhaust fan assemblies 160. The partition member 170 functions to partition the intake passage Pi and the first exhaust passage Po1. For this purpose, the partition member 170 may be formed in a plate shape having a shape and size corresponding to the cross section of the first exhaust passage Po1. Also, the first and second exhaust fan assemblies 160 are fixed to the partition member 170 substantially. Accordingly, the partition member 170 may be referred to as a fan mount for fixing the first and second exhaust fan assemblies 160.

A plurality of exhaust openings 171 and 173 are formed in the partition member 170. The exhaust openings 171 and 173 are communicated with the first exhaust flow path Po1 from the intake flow path Pi by the first and second exhaust fan assemblies 160 and substantially the exhaust fan As shown in FIG. The exhaust openings 171 and 173 are composed of a plurality of openings and are respectively positioned substantially in the upper right chamber of the exhaust fan. 3 and 4, the leftmost and rightmost ones in the drawing are referred to as an outer exhaust opening 171, and the portion between the outer exhaust opening 171 is referred to as an inner exhaust opening 173.

A plurality of air guides 181 and 183 are provided on the second flow path. The air guide 180 serves to define air exhausted to the first exhaust passage Po1 through the outer exhaust openings 171 and 173 and the inner exhaust openings 171 and 173. [ The air guide 180 guides air flowing through the first exhaust passage Po1 to a second exhaust passage Po2 to be described later or guides the air flowing through the first exhaust passage Po1 to the outdoor exhaust port 141. [

In the present embodiment, the air guide 180 defines air exhausted through the outer exhaust openings 171, 173 and the inner exhaust openings 171, 173. The air guide 180 includes first and second air guides 181 and 183, each of which includes two air guides. The first and second air guides 181 and 183 extend obliquely at a predetermined angle with respect to the vertical direction so that the upper and lower ends thereof are positioned on the outdoor air outlet 141 and the partition member 170, respectively. The first air guide 181 is positioned to be spaced apart from the left and right and the second air guide 183 is positioned between the first air guides 181 so as to be spaced laterally.

More specifically, the upper end of the first air guide 181 is in contact with both side ends of the outdoor air outlet 141. The lower end of the first air guide 181 is in contact with the upper surface of the partition member 170 corresponding to the outside of the outer air exhaust openings 171 and 173, respectively. The upper end of the second air guide 183 is located inside the outdoor air outlet 141. At this time, the upper end of the second air guide 183 is positioned adjacent to both ends of the outdoor air outlet 141 relative to a point where the outdoor air outlet 141 is divided into three equal parts. The lower end of the second air guide 183 is in contact with the upper surface of the partition member 170 corresponding to the gap between the outer exhaust opening 171 and the inner exhaust openings 171 and 173. The outer air exhaust openings 171 and 173 are formed by the first and second outer air exhaust fans 153 and 163 as spaces between the first and second air guides 181 and 183, Respectively. The air discharged through the inner air exhaust openings 171 and 173 by the first and second inner air exhaust fans 155 and 165 is introduced into the space corresponding to the space between the second air guides 183, Flow together.

Due to the size and position of the outdoor exhaust 141, the first and second outdoor exhaust fans 153 and 163 (see FIG. 1) are different from the air flowing by the first and second inner exhaust fans 155 and 165 ) Flows relatively slopingly. In other words, the air that is flowed by the first and second inner exhaust fans 155 and 165 flows in a relatively straight line direction relative to air flowing by the first and second outer exhaust fans 153 and 163 . Accordingly, the flow resistance of air flowing by the first and second outer exhaust fans 153 and 163 is larger than that of the first and second inner exhaust fans 155 and 165. In order to solve such a problem, in this embodiment, the left and right distances between the second air guides 183 at the same height are equal to 2 (the left and right distances between the first and second air guides 181 and 183) Is set to a value less than double. In other words, at the same height, the flow cross sectional area between the second air guides 183 is set to a value less than the sum of the flow cross sectional areas between the first and second air guides 181 and 183.

On the other hand, an exhaust duct 190 is provided on the upper surface of the cavity 110. The exhaust duct 190 defines a second exhaust passage Po2 together with an upper surface of the out casing 140. [ The second exhaust passage Po2 serves to guide the air that has flowed through the first exhaust passage Po1 to the indoor exhaust port 113. [ To this end, the rear end of the second exhaust passage Po2 communicates with the upper end of the first exhaust passage Po1. The front end of the second exhaust passage Po2 communicates with the indoor exhaust port 113. [

Although not shown, a damper member may be provided on the exhaust duct 190. The damper member selectively opens and closes the second exhaust passage Po2. That is, when the air flowing through the first exhaust passage Po1 is discharged to the room through the room exhaust port 113, the damper member opens the first exhaust passage Po1. When the air flowing in the first exhaust passage Po1 is discharged to the outside through the outdoor air outlet 141, the damper member shields the first exhaust passage Po1.

Further, a filter member (not shown) may be provided on the exhaust duct 190. The filter member is configured to remove contaminants contained in the air discharged through the indoor exhaust port (113) after flowing through the second exhaust passage (Po2).

Although not shown, the microwave oven 100 is provided with a heating source for cooking food in the cooking chamber 111. For example, the microwave oven may include a magnetron for radiating microwaves into the interior of the cooking chamber 111, a heater for supplying heat to the inside of the cooking chamber 111, and a high- A convection device or the like may be provided.

Hereinafter, the operation of the first embodiment of the microwave oven combined with the hood according to the present invention will be described in more detail.

First, contaminants, such as moisture, oil, and odorous substances, are generated in the process of cooking food in a cooking device installed below the microwave oven 100. When the first and second exhaust fan assemblies 160 operate, the air containing the contaminants is sucked into the microwave oven 100.

More specifically, when the first and second exhaust fan assemblies 160 operate, air containing contaminants is sucked through the intake port 121 and flows through the intake passage Pi. However, in the present embodiment, the first and second exhaust fan assemblies 160 are located adjacent to the intake port 121, as compared with the conventional case where the exhaust fan assembly is installed on the upper surface of the cavity. Accordingly, when the first and second exhaust fan assemblies 150 and 160 are operated, the efficiency of intake of air through the intake port 121 can be improved as compared with the conventional art. The diffusion of the air including the contaminants generated in the course of cooking the food in the cooking device can be prevented by virtue of the efficiency of the suction efficiency of the air.

The air flowing through the intake passage Pi is transferred from the intake passage Pi to the first exhaust passage Po1 by the continuous operation of the first and second exhaust fan assemblies 160. [ In this embodiment, a plurality of exhaust fans constituting the first and second exhaust fan assemblies 160, that is, a first outer exhaust fan 153, a second outer exhaust fan 163, The air to be delivered from the first exhaust passage Po1 to the second exhaust passage Po2 is divided by the first and second air guides 181 and 183 by the two inner exhaust fans 155 and 165, do. The first and second outer exhaust fans 153 and 163, which are relatively inclined with respect to the flow of the air, 165 are relatively larger than those of the space in which the air flows. Accordingly, the flow resistance of air flowing by the first and second exhaust fan assemblies 160 can be relatively reduced.

On the other hand, the air that has flowed through the first exhaust passage Po1 is discharged to the inside or outside of the room through the indoor air outlet 113 or the outdoor air outlet 141. [ That is, the air that has flowed through the first exhaust passage Po1 is selectively discharged to the room or the outside.

More specifically, when air is discharged to the room through the indoor air outlet 113, the second exhaust air passage Po2 is opened by the damper member, and the outdoor air outlet 141 is shielded. Therefore, the air that has flowed through the first exhaust passage Po1 is transferred to the second exhaust passage Po2. The air having flowed through the second exhaust passage (Po2) is discharged to the room through the indoor exhaust port (113). At this time, the contaminants contained in the air are removed by the filter member in the course of the air flowing through the second exhaust passage Po2.

On the other hand, when the air is discharged to the outside through the outdoor air outlet 141, the damper member shields the second air outlet Po 2, and the outdoor air outlet 141 is opened. Therefore, the air that has flowed through the first exhaust passage Po1 is transferred to the hood through the outdoor exhaust port 141 and is discharged to the outside of the room.

Hereinafter, a second embodiment of a microwave oven combined with a hood according to the present invention will be described in detail with reference to the accompanying drawings.

Fig. 5 is a front view showing a main portion of a second embodiment of the hood-and-cowl microwave oven according to the present invention. The constituent elements of the present embodiment, which are the same as those of the first embodiment of the present invention, refer to the reference numerals of FIGS. 1 to 4, and a detailed description thereof will be omitted.

Referring to FIG. 5, in this embodiment, the air guide 180 ', that is, the first and second air guides 181' and 183 'is bent a plurality of times at a predetermined angle. Therefore, in the case of the upstream side relative to the flow direction of the air, the flow cross sectional area of the space between the first and second air guides 181 'and 183' and the space between the second air guides 183 ' Is relatively increased in comparison with the first embodiment of the present invention described above. However, in the case of the upstream side relative to the flow direction of the air, since the first and second exhaust fan assemblies 160 are relatively adjacent to each other, the flow velocity of the air is also higher. The first and second exhaust fan assemblies 160, i.e., the first and second outer exhaust fans 153 and 163 (hereinafter, referred to as " first " And the air flowing through the first and second inner exhaust fans 155 and 165 can be prevented from being impinged upon the first and second air guides 181 'and 183' . Especially, the air flowing by the first and second outer exhaust fans 153 and 163 can be prevented from colliding with the first air guide 181 '. Therefore, according to the present embodiment, more efficient air flow can be expected as compared with the first embodiment of the present invention.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims and their equivalents. .

In the above-described embodiments, the exhaust fan assembly is described as being two, but only one exhaust fan assembly may be provided. In such a case, the air guide will also be composed of three.
