Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to kitchen furniture with a built-in microwave oven, which is constructed by incorporating a microwave oven into a cabinet.

[Prior art]

As a built-in type microwave oven kitchen furniture that incorporates a microwave oven, for example,
A storage cabinet with a microwave oven having a structure as shown in the figure is conventionally known.

This conventional storage cabinet is composed of a cabinet consisting of an upper rack 1 having a storage section with a door, a lower rack 2 having a drawer, etc., and a range rack 3 disposed between the upper rack 1 and the lower rack 2. The microwave oven 4 is built into the microwave rack 3 of the cabinet.

As shown in FIGS. 4A and 4B, the heat emitted from the microwave oven 4 is transferred to the outer peripheral surface of the microwave oven 4 housed in the oven rack 3 through the outside air intake port 4b of the microwave oven main body 4a. It is cooled by outside air (indicated by arrow b in Figure 4) drawn into the tank, and the outside air after this cooling (indicated by arrow c in Figure 4).
is exhausted to the outside of the microwave oven main body 4a from an exhaust port 4c formed at the rear of the microwave oven main body 4a,
A cooling air flow path A is formed for discharging the outside air exhausted to the outside of the microwave oven main body 4a further to the outside of the microwave rack 3.

This cooling air flow path A includes an intake passage 3a formed between the range rack 3 and the lower stand 2, an exhaust passage 3b formed between the range rack 3 and the upper stand 1, and the back and both sides of the range rack 3. A connection space 3c is formed in the microwave oven main body 4a and sends outside air exhausted to the outside of the microwave oven main body 4a to the exhaust passage 3b.
It is composed of and.

Therefore, the heat emitted from the microwave oven 4 (especially when the microwave oven 4 is used as an oven) is transferred from the intake passage 3a to the microwave oven 4 by a fan (not shown) disposed inside the microwave oven 4. It is cooled by outside air drawn inside.

The outside air that has cooled the inside of the microwave oven 4 is exhausted to the outside of the microwave oven main body 4a from the exhaust port 4c of the microwave oven main body 4a, and then passes through the connection space 3c to the outside of the storage from the exhaust passage 3b. and is configured to be forcibly evacuated.

[Problems with conventional technology]

However, it is known that the heat emitted from the inside of the microwave oven 4 is concentrated in the upper part a on the front side of the microwave oven main body (hereinafter referred to as heat concentration area a) where the opening/closing door 6 of the microwave oven 4 is disposed. In the conventional storage heat exhaust structure, the hot air emitted from the heat concentration area a and the cooled outside air flowing through the cooling air flow path A meet in the heat concentration area a, There was a problem in that the packing of the grill body disposed above the microwave oven was easily deformed by heat.

This invention was devised in view of the current situation, and its purpose is to direct the hot air emitted from the heat concentration area and the cooled outside air flowing through the cooling air flow path into the heat concentration area. To provide inexpensive kitchen furniture with a simple configuration that can improve the heat exhaust efficiency of kitchen furniture with a microwave oven and greatly improve the durability of this type of kitchen furniture. This is what I am trying to do.

[Means for solving problems]

In order to achieve the above object, in this invention, a microwave oven is housed in the middle part of the cabinet, and a space between the microwave oven and the upper part of the cabinet is provided to exhaust the heat emitted from the microwave oven. In the built-in microwave oven kitchen furniture, the kitchen furniture has a built-in type microwave oven, in which an exhaust passage is formed, and a grill body is disposed at the outlet end of the exhaust passage. and an inclined piece extending diagonally downward from the rear end edge of the mounting piece, the inclined piece having a lower end thereof. The microwave oven is characterized in that it is configured to extend to a position that covers the area on the upper front side of the microwave oven where heat is concentrated.

[Function] Therefore, in the kitchen furniture with a microwave oven according to this invention, the hot air emitted from the heat concentration area and the cooled outside air flowing through the cooling air flow path are separated at the heat concentration area. Therefore, a heat shield plate is installed on the back side of the grill body attached to the outlet end of the exhaust passage, and this heat shield plate exhausts the cooled outside air flowing through the cooling air flow path to the outside from the upper part of the exhaust passage. In addition, the present invention is characterized in that the hot air emitted from the heat concentration area is exhausted to the outside from the lower part of the exhaust passage.

〔Example〕

This invention will be described in detail below based on an embodiment shown in the accompanying drawings.

As shown in FIG. 1, the storage cabinet with a microwave oven according to this embodiment, like the conventional storage cabinet, has an upper stand 10, a lower stand 20, and a cabinet between the upper stand 10 and the lower stand 20. A microwave oven 40 having an oven function is built into the microwave rack 30.

The upper stand 10 has a door 11, and an interior 12 is configured as a storage.

The lower stand 20 is formed with drawers 21, 22, and 23 for storing tableware and the like, for example.

At the bottom of the front opening side of the microwave rack 30,
A grill body 33 for sucking outside air is disposed inside the microwave rack 30, and a grill body 33 for exhausting hot air that has cooled the microwave oven body to the outside is provided at the upper part of the front opening side of the microwave rack 30.
4 are arranged.

Further, a cooling air flow path A is formed on the outer circumferential surface of the microwave oven 40 housed in the microwave oven rack 30 for cooling and exhausting the heat generated from the microwave oven 40 to the outside.

This cooling air flow path A includes an intake passage 30a formed between the range rack 30 and the lower stand 2, an exhaust passage 3b formed between the range rack 30 and the upper stand 10, and the back and both sides of the range rack 30. and a connection space 30c for sending the cooled outside air to the exhaust passage 30b.

The microwave oven 40 is a so-called oven function type microwave oven equipped with an open flame type heating means, and is equipped with a fan (not shown) for sucking and exhausting outside air. , other configurations and operations are the same as those of known ones, so detailed explanation thereof will be omitted here.

Further, on the back surface of the grill body 34, hot air emitted from the heat concentration area a and the cooling air flow path A are provided.
The cooling outside air flowing through the heat concentration area a
A heat shield plate 60 is attached to separate the flow in some areas.

As is particularly clear from FIG. 2, the heat shield plate 60 includes a mounting piece 6a attached to the back surface of the grille body 34, and a mounting piece 60a extending diagonally downward from the rear edge of the mounting piece 60a. an inclined piece portion 60b;
The mounting piece portion 60a is configured to be fitted into the central horizontal bar portion 34c of the grill body 34, which is formed in a U-shape in cross section. Of course, the mounting piece 60a is attached to the central horizontal beam 3 using a fixing device such as a screw or a heat-resistant adhesive.
It can also be fixed to 4c.

Further, the inclined piece part 60b is arranged so that its lower end extends to a position covering the heat concentration area a, and as a result, the outside air flowing through the cooling air flow path A is divided by the inclined piece part 60b. flows out from the outlet 34a above the grill body 34,
Further, the hot air emitted from the heat concentration area a flows out from the outlet 34b under the grille body 34 defined by the inclined piece part 60b, and is separated from the outside air flowing through the cooling air flow path A and the heat concentration area a. The structure is such that the emitted hot air does not merge in the heat concentration area a.

Although this invention has been explained by taking as an example the case where the heat shield plate 60 is applied to the storage cabinet of the above embodiment, it is of course possible to apply it to kitchen furniture with a microwave oven having other configurations. Moreover, the heat shield plate 60 can also be attached to existing microwave oven kitchen furniture having the grill body 34.

[Effect of idea]

As explained above, in this invention, a heat shield plate is provided on the back side of the grill body attached to the outlet end of the exhaust passage, and the cooling air flows through the above-mentioned cooling air flow path by the inclined piece part of the heat shield plate. The structure is configured so that the outside air after cooling is exhausted to the outside from the upper part of the exhaust passage, and the hot air emitted from the heat concentration area is exhausted to the outside from the lower part of the exhaust passage, so that the hot air emitted from the heat concentration area and the above cooling are exhausted. The cooled outside air flowing through the air flow path can be separated at the heat concentration area, and as a result, the hot air emitted from the heat concentration area does not mix with the outside air and increase the overall exhaust temperature. Therefore, it is possible to reliably prevent thermal deformation of the packing disposed above the heat shield plate of the grill body, and since the structure is simple, it can be applied at low cost, and many other effects are achieved.
