Abstract

PURPOSE:To provide an electric stove equipped with a fan, which is capable of reducing a temperature difference generated in the up-and-down direction in a room, by a method wherein a damper, opening and closing an upper surface blow-off port and a front surface blow-off port, is operated in conjunction with a speed regulating switch, effecting the strong operation and the weak operation of a cross flow fan. CONSTITUTION:A quartz tube heater generates heat by the conduction thereof while radiation heat from the surface thereof and reflected radiation heat from a reflector 6 are projected forwardly. Further, when a damper 8 is operated by a knob so as to close an upper surface blow-off port 2 and open a front surface blow-off port 3, a contact 11 is closed by the operation of a speed regulating switch 10 while the contact 12 of the same is opened, therefore, the weak operation of a cross flow fan 3 is effected and slow airflow is sent out forwardly by the weak operation of the cross flow fan 3. When the front blow-off port 3 is closed and the upper blow-off port 2 is opened in the same manner, the contact 12 is closed and the contact 11 is opened by the operation of the speed regulating switch 10, therefore, the strong operation of the cross flow fan 3 is effected to send strong airflow upwardly.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electric stove with a fan.

BACKGROUND OF THE INVENTION Conventionally, this type of electric stove with a fan has been constructed as shown in FIGS. 5 and 6. That is, a reflecting plate 102 having a plurality of air holes 103 is arranged on the back side of the quartz tube heater 1o1, and an axial fan 104 is arranged at the rear of this reflecting plate 102. When energized, the quartz tube heater 101 generates heat, and the radiant heat from its surface and the reflected radiant heat from the reflector plate 102 are radiated forward.At the same time, the heated air around the quartz tube heater 101 is transferred to the axial flow fan. Air hole 1 by 104
It was sent forward by the airflow blown out from 03.

Problems to be Solved by the Invention In such a conventional configuration, air can only be sent forward by the axial fan 104, which gives a cool feeling to the human body in front of the axial fan 104. There was a problem in that it was not possible to increase the amount of air blown to agitate the indoor air and reduce the temperature difference that occurred in the vertical direction within the room.

Taking these problems into consideration, the present invention allows air to be blown in the front direction of the fan, and furthermore, it is possible to agitate the indoor air and reduce the temperature difference that occurs in the vertical direction in the room without giving a cool feeling to the human body. The purpose of this invention is to provide an electric stove with a fan.

Means for Solving the Problem In order to solve this problem, the present invention forms an upper surface air outlet at the upper front of the outer frame, a front air outlet at the front surface, and a suction port at the rear surface. a heater inside, a reflector provided on the back of the heater, and a cross-flow fan provided on the top of the heater, and further provided with a damper that alternately opens and closes the top air outlet and the front air outlet, In conjunction with the opening and closing of this damper, the cross-flow fan is equipped with a speed adjustment switch that switches to a low operation notch when the front outlet is open and to a strong operation notch when the top outlet is open. It is something.

With this configuration, when the damper closes the top air outlet, the front air outlet opens, and at the same time, the speed control switch causes the once-through fan to operate at low speed, allowing a breeze to be sent forward. Therefore, when the damper closes the front air outlet, the upper air outlet is open, and at the same time, the speed control switch causes the cross-flow fan to operate strongly, so strong wind is sent upward.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 4.

In the figure, 1 is the outer frame, and the upper surface has an upper air outlet 2,
A front air outlet 3 is provided on the front surface, and a suction port 4 is provided on the rear surface. Inside the outer frame 1, there is a rod-shaped quartz tube heater 6 placed horizontally, a reflector 6 provided on the back of the quartz tube heater 6, and a through-flow 7 amperage provided on the top of the quartz tube heater 5. 7. Further, there is a damper 8 that alternately opens and closes the top air outlet 2 and the front air outlet 3, a knob 9 that operates this damper 8, and a cross-flow fan 7 that operates in conjunction with the opening and closing of the damper 8 to open and close the front air outlet 3. The speed adjustment switch 10 is equipped with a speed adjustment switch 10 that switches to the low operation notch when the air outlet 2 is open, and to the strong operation notch when the top air outlet 2 is open. be.

In the above configuration, when energized, the quartz tube heater 6 generates heat, and radiant heat from its surface and reflected radiant heat from the reflector plate 6 are radiated forward.

Furthermore, when the damper 8 is operated using the knob 9 to close the top air outlet 2 and open the front air outlet 3, the speed adjustment switch 1
The contact 11 closes and the contact 12 opens due to the operation of o, so that the cross-flow fan 3 is operated at low speed and a breeze is sent forward.

Similarly, when the front air outlet 3 is closed and the upper air outlet 2 is opened, the contact 12 closes due to the operation of the speed control switch 1o.
Since the contact point 11 opens, the cross-flow fan 3 operates strongly, and strong wind is sent upward.

Effects of the Invention As is clear from the description of the embodiments above, according to the present invention, it is possible to send a breeze forward, air warmed by the heater can be sent forward, and strong wind can be sent upward, which can be harmful to the human body. It is possible to agitate the indoor air without giving a cool feeling and reduce the temperature difference that occurs in the vertical direction of the room, resulting in a comfortable heating effect.
