Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION This invention relates to a built-in heating cooker having a bottom evacuation device.

2. Description of the Related Art A conventional built-in heating cooker having a downward evacuation device of this type has a structure as shown in FIGS. 4 to 6.

That is, the cooking device main body 1 has a heating device 3 and a cooling device 4 inside a housing 2, and is provided with a top plate for placing a pot on the upper side. A bottom evacuation device 7 having a fan section 6 inside is provided on the bottom surface 2a of the casing 2. A pack grill 8 is attached to a rear part of the main body 1, and the pack grill 8 has an intake port 8 for cooling the main body 1.
a, an exhaust port 8b is provided, and the exhaust port 8b also serves as a ventilation port for cooling the lower evacuation device 7. Each of them constitutes a cooling path for the main body 1 and an intake path for the downward exhaust device 7.

However, when the conventional structure generates oil smoke 9 such as when cooking tempura, cooling is carried out from the air inlet 8a provided in the pack grill 8 for cooling the main body 1. air 1o
When taking in the oil, the oil smoke 9 is also sucked in at the same time, and the oil content of the oil smoke 9 adheres to the heating device 3 and the like inside the main body 1. In addition, in order to prevent oil from adhering, an oil removal filter 11 or the like is sometimes provided below the intake port 8a, but since the cooling air 1o is sucked through the filter 11, there is a problem in that the cooling efficiency decreases. .

Therefore, the present invention is intended to prevent oil smoke 9 and the like from being simultaneously sucked in from the cooling air intake port 8a of the cooking device main body 1 provided in the pack grill 8.

Means for solving the problems and technical means of the present invention for solving the above problems are as follows:
The front side of the pack grill is provided with a vent for the downward exhaust device and an exhaust port for exhausting the cooking device main body, and the rear side is provided with an intake port for cooling the cooking device main body. It is.

For production The effect of this technical means is as follows.

That is, the front side of the pack grill is provided with a vent for the downward exhaust device and an exhaust vent for exhausting the heating cooker body.
There is an air inlet for cooling the main unit on the rear side, so if oil smoke is generated from a pot, etc., it will be sucked into the vent of the lower exhaust device, and the oil smoke will not reach the air intake of the main unit. Cooling air that does not contain oil is sucked in from the cooling air inlet of the main body.

In addition, even if the downward exhaust device does not operate, the exhaust port for discharging the exhaust gas from the main unit is provided on the front side of the pack grille, so oil smoke, etc. will be diffused by the exhaust air from the exhaust port, and the exhaust gas will be dissipated from the rear side of the bank grille. There is no suction from the intake port on the side body.

As a result, even in situations where oil smoke is produced, such as when cooking tempura, oil will not be contained in the air intake path of the appliance itself, eliminating the need for a filter to remove oil, and eliminating the need for a filter to reduce cooling efficiency. It is also possible to reduce the number of parts and improve cooling performance.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

In FIGS. 1 to 3, 12 is the cooking device main body, 1
3 is a housing having a heating device 14, a cooling device 16 inside, and a top plate 16 for placing a pot on the top. Housing 1
A lower exhaust device 17 is provided on the bottom surface portion 13a of No. 3. A pack grill 1i is attached to the upper rear portion of the main body 12 of the main body. A vent hole 19 is provided in the front face portion 18a of the pack grille 18, and constitutes an intake path entrance of the downward exhaust device 17 and an exit of the cooling path of the main body 12. An intake port 20 is provided on the rear surface portion 18b of the pack grille 18 at a position not facing the ventilation port 19, and constitutes an entrance of a cooling path for the main body 12.

Next, the operation of this embodiment will be explained.

The cooling path for the main body 12 is such that when the cooling device 15 operates, outside air 21 is sucked in from an intake port 20 provided on the rear surface 18b of the pack grill 18, and is guided into the cabinet interior 22 from the space provided on the bottom surface 13a of the housing. After that, the housing 1
3 and cools the heating device 14 and the like. after that,
It passes through the slit 23a of the partition plate 23 on the rear surface of the casing 13 and is discharged outside the device through the vent 19 on the front surface 18a of the pack grill 18. The exhaust path of the lower exhaust device 17 is such that oil smoke 9 and the like are sucked through the vent 19 of the front part 18a of the pack grill 18 by the operation of the fan section 17a inside the lower exhaust device 17, It is discharged outdoors from 17b.

Now, when oil smoke 9 or the like is generated when cooking tempura, etc., the oil smoke 9 is sucked through the vent 19 on the front part 18a of the pack grill 18 by the operation of the lower exhaust device 17, and does not reach the intake port 20 on the rear part 18b. , outside air 21 sucked from the intake port 20
does not contain oil such as oil smoke 9. Therefore, the main body 12
Outside air 21 containing oil does not enter inside.

Furthermore, even when the lower exhaust device 17 does not operate, the main body 1 is always
2 Defecation 24 after internal cooling is constantly released, and oily smoke 9
etc. are diffused by exhaust gas and do not reach the intake port 20 of the rear surface portion 18b of the bank grille 18.

As a result, for cooling the main body 12, the outside air 2 containing oil is used.
1 does not intrude into the interior, and oil does not adhere to the internal parts of the main body 12. Therefore, there is no need for a filter for removing oil adhesion, and there is an effect that the cost is reduced due to the reduction of filters, and the cooling efficiency is improved without reducing the cooling effect due to the attachment of the filter.

More than the effects of the invention, as is clear from the examples, the present invention provides a vent in the front part of the pack grille for the suction of the downward exhaust device and for the exhaust of the main body, and an intake port for the main body intake in the rear part. By installing it in a position that does not face the vent mentioned above, oil smoke will not be mixed into the cooling air inside the appliance, and oil will not adhere to the parts, eliminating the need for a filter to remove oil and increasing costs associated with filter installation. and can prevent a decrease in cooling efficiency.
