Description

  The present invention relates to a cooking device that heats an object to be heated by a heater, a microwave, or the like, and more particularly to a built-in cooking device that is suitable for a floor-standing type and used under an IH or gas stove.

  Conventionally, this type of cooking device has a high frequency generating means (magnetron) that outputs a high frequency as means, and rapidly spreads as a microwave oven that can efficiently heat an object to be heated in a heating chamber in a short time. did.

  However, there is an inconvenience that the width of cooking is limited only by heating by high frequency heating.

  Then, the high frequency heating cooking apparatus which added the electric heater which heat | fever-generates in a heating chamber and enabled oven heating is proposed (for example, refer patent document 1).

  FIG. 6 is a perspective view showing a state in which a conventional high-frequency heating cooking apparatus is incorporated in a system kitchen, and FIG. 7 is a perspective view when the door of the conventional heating apparatus body is opened and closed.

  As shown in FIGS. 6 and 7, a system kitchen 1 and a heating device body 2 incorporated in the system kitchen 1 are configured. In addition to the door 4 that opens and closes the heating chamber 3 with a door handle 4a, an operation unit 6 for operating the heating means 5 is provided on the front surface of the heating apparatus body 2, and the operation unit 6 is operated to perform various types of cooking. It was like that.

  Moreover, the heating means 5 is installed below the heating chamber 3 in which a relatively large number of non-use spaces existed in order to effectively use the spaces.

  FIG. 8 is a perspective view when a conventional heating apparatus body is placed on a carriage and a storage shelf is opened.

  In order to easily install the cooking device, the heating device body 2 is placed on a movable carriage 7, and both sides of the heating apparatus body are fixed to the carriage 7 with metal fittings 8. The carriage 7 is provided with a storage shelf 9 that slides in the front-rear direction. The storage shelf 9 is a drawer shelf that can store an accessory oven plate (not shown) or the like when not in use.

  On the front surface of the storage shelf 9, a decorative board 10 is fixed to the storage shelf 9 by a joining means.

  FIG. 9 is a cross-sectional view of the main part of the cooling device below the conventional heating device body. A cooling device 14 disposed below the heating chamber 3 sucks cold cooling air 16 from an intake hole 15 provided in the bottom plate 12 to cool high-frequency generating means (not shown).

JP 59-212626 A

  By the way, recently, there is an increasing demand for a built-in heating cooking apparatus incorporated in a system kitchen or the like. Such a built-in type cooking device has a fixed size for the storage section prepared in the system kitchen, etc., in order to increase the space in the cooking cabinet in a limited space, during high-frequency heating means or during operation The cooling means for cooling the high-frequency heating means that becomes high temperature is installed below the heating chamber so that the built-in space can be used effectively.

  As shown in the sectional view of the main part of the cooling device below the heating device main body in FIG. 9, the cooling device 14 disposed below the heating chamber 3 is cooled for cooling from the intake hole 15 provided in the bottom plate 12. Air 16 is sucked in and the high frequency generating means (not shown) is cooled.

  However, in the conventional configuration, the space 13 between the top plate 11 of the carriage 7 and the bottom plate 12 of the heating device body is very narrow in order to effectively use the space, and the cooling air 16 flows. Not only is the space narrow, but when the cooling air is sucked from the suction holes 15 provided in the bottom plate 12, the air flow bends at right angles, so that the suction resistance increases and the cooling efficiency decreases. there were.

  This invention solves the said conventional subject, and it aims at providing the cooking apparatus which can improve cooling of a heating apparatus main body, after utilizing built-in space effectively.

In order to solve the above-described conventional problems, the cooking device of the present invention is a cooking device having a heating device body and a movable carriage on which the heating device body is placed.
The heating device main body includes a door that opens and closes a front opening of a heating chamber, a heating unit that heats the heating chamber, an operation panel that is provided at an upper portion of the door and sets and displays heating conditions, and the heating chamber A cooling device installed below, a bottom plate provided with the cooling device, and an intake hole provided in the bottom plate,
The carriage includes an outer frame, a decorative plate provided on the front surface of the outer frame, an upper plate for fixing the heating device body, a plurality of wheels, and a storage shelf configured inside the outer frame, An outside air intake hole for taking in outside air, and an intake hole that is provided in the upper plate and allows air in the storage shelf to flow,
The air in the storage shelf that flows in from the intake hole provided in the upper plate supplies cooling air to the cooling device through a straight path with respect to the intake hole that is an intake port provided in the bottom plate. It is set as the structure which carries out.

  As a result, the intake resistance of the cooling air can be reduced, and the built-in space can be used effectively, and the cooling performance of the built-in heating cooking apparatus can be improved.

  The heating cooking apparatus of the present invention takes in cooling air from a plurality of intake holes capable of moving air on the upper surface of the carriage, thereby increasing the space in which air flows and the flow of wind to the bottom plate of the heating apparatus body. It becomes linear, not only reduces the intake resistance of cooling and improves cooling efficiency, but also circulates the air in the storage shelf and ventilation in the storage shelf can also improve cleanliness it can.
