2. Description of the Related Art In recent years, as cooking appliances have been systematized, an electric range has been unitized together with a heater (for example, an electric oven).

A conventional electric range unit has a structure as shown in FIG. This conventional example is a case of an embedded electric range unit. In FIG. 5, 1 is a sink of the system kitchen. Reference numeral 2 denotes a top heater portion of the electric range unit, which is mainly formed by a plate 4 to which the spiral sheathed heater 3 is locked and a casing-like top plate 5 that covers it from below, and is dropped into the upper opening of the sink 1. Be done. Reference numeral 6 denotes a heater (here, an electric oven), which is installed inside a heater case 7 (here, an oven base), and the oven base 7 is installed from the front of the sink 1 to the inside. 7a is an intake hole of the oven base 7, and 7b is an exhaust hole of the oven base 7. Reference numeral 8 denotes a main body of a microwave oven unit that is mounted and fixed on the upper surface of the oven base 7 and is connected to the top heater unit 2. A handle 9 of the roaster unit and a watt controller for controlling the electric power of the spiral sheathed heater 3 are provided on the front face. It is equipped with knobs 10 and the like.

However, in such a conventional configuration, when the electric oven 6 is used, the outside air flows into the inside of the oven base 7 through the intake hole 7a as shown by the arrow A, and the electric oven 6 operates. Heat convection occurs, flows out from the exhaust hole 7b to the outside as shown by an arrow B, and rises along the front surface of the main body portion 8 of the electric range unit. Therefore, the main body portion 8 located in the path of the rising heat convection is heated. The handle 9 of the roaster section and the knob 10 of the watts controller provided on the front surface become extremely hot, and there is a problem that when the oven is cooked for a long period of time, the temperature will rise further and the user may be burned. there were.

Further, when the control unit is formed by an electronic circuit or the like, there is a problem that electronic components may be destroyed by the heat convection.

The present invention solves such a problem. Even when cooking in an oven takes a long time and heat convection continues to flow out from the exhaust hole 7b, high temperature such as the handle 9 of the roaster portion or the watt controller knob 10 is high. Protects the user from the risk of burns, etc., and prevents electronic components from being destroyed by thermal convection even when the control part is formed of an electronic circuit, and is a safe and high-quality electric range. It is intended to provide a unit.

Means for Solving the Problems In order to solve this problem, the present invention provides an upper surface of a heater case in which a heater main body is housed, and a lower surface of an electric range mounted on the upper surface and having an operating portion on the front surface. A ventilation space communicating with the outside air is provided between the front and the rear, and a ventilation device is provided at the rear of the ventilation space.

Further, according to the present invention, a ventilation space communicating with the outside air is provided between an upper surface of a heater case in which the heater main body is housed and a lower surface of an electric range mounted on the heater case and having an operating portion on the front surface. An air blower is provided at the rear of the electric range, and an air suction hole for blowing air is provided behind the top plate of the electric range.

With the above configuration, when the heater is used, outside air flows into the inside of the heater case through the intake hole of the heater case,
When the heater creates heat convection, flows out from the exhaust hole, and tries to rise along the front surface of the main body of the electric range unit, a ventilation space provided below the electric range is generated by the blower. Since the air convection that flows flows out into the outside air, the heat convection generated by using the heater is swept forward, and the operating part of the electric range located above it is not heated by the heat convection. As a result, even when the heater is used for a long time, it can protect the user from the risk of burns, etc., and even if the operating part is formed by an electronic circuit, the electronic parts are prevented from being destroyed by thermal convection. However, safety and quality can be improved.

Furthermore, the air blower allows the air sucked from the air suction hole at the rear of the top plate to pass through the ventilation space as a convection, and the heat convection generated by the use of the heater is more effectively swept forward to ensure safety, The quality can be further improved.
