Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a range hood fan which is installed above a cooking appliance such as a gas range and an electric range in a kitchen and sucks and discharges fumes such as oil smoke and combustion gas generated by cooking.

[0002]

2. Description of the Related Art In a range hood fan installed in a kitchen, a back plate, a top plate, and left and right side plates, which are formed by pressing a steel plate into a predetermined shape and cutting it, are spot-welded, followed by painting to finish the front and lower parts. A hood body is constructed by forming an open hood member, hooking a front plate formed by pressing and painting a steel plate to the front opening of the hood member, and detachably attaching it by means such as screwing, Moreover, the fan unit motor is screwed and fixed to the back plate of the hood member, and the fan casing is fixed to the back plate and top plate of the hood member, and the fan is attached to the rotary shaft of the motor in the fan casing. ing.

The cord and power cord connected to the motor of the blower unit mounted in the hood body described above are attached to the front plate of the hood body for operation and operation.
Stop switch, blower operating status "strong", "medium"
Connectable and separable via cords on the switch box side such as "weak" changeover switches via male / female connectors, and installed over the top plate, left and right side plates and back plate and left and right side plates of the hood member. The filter mounting frame is fixed to the bottom plate, and the filter is detachably mounted on the filter mounting frame.

[0004]

As described above, in the conventional range hood fan, the back plate, the top plate, and the left and right side plates are connected and fixed by spot welding or the like, and the back plate and the left and right sides of the hood member. The range hood fan is completed only by attaching the filter mounting frame to the bottom plate laid across the side plates, and mounting the filter on the filter mounting frame, which requires time and labor for manufacturing, assembling, and further on-site mounting. Is.

Further, the wiring of the motor of the blower unit fixed to the inside of the hood member, the various switches mounted on the front plate detachably attached to the front of the hood member, and the power source is as described above. The cord that is connected to the motor and the cord that is electrically connected to the switch on the front plate side are configured so that they can be connected and disconnected via the male and female connectors. It is necessary to separate and reconnect the male and female connectors, and the cord is bridged from the hood member to the front plate side and exposed to the hot air rising from the range. Protect the cord and connector from heat. There is a problem that protective means and the like must be equipped.
Furthermore, since the electrical components such as switches are attached to the front plate that can be attached to and detached from the hood member, even if the front plate is removed from the hood member and cleaned, the above electrical components should be protected from water. It must be done with care, so a complete wash etc. is not possible.

The present invention has been made in view of the problems of the above-mentioned conventional techniques, and the object of the invention is to:
It is an object of the present invention to provide a range hood fan that is easy to assemble the blower unit to the hood body and can be easily installed and installed, has improved maintainability after installation, and is excellent in cleanability.

[0007]

The technical means taken by the present invention to achieve the above-mentioned object is a disassembled hood body having an opened lower surface formed by assembling a top plate, left and right side plates, a front plate and the like. A fan unit equipped with a filter is detachably attached to the inside of the fan, and a control unit for controlling the operation and stop of the blower is attached to the fan unit, and a receiving unit is provided in the blower unit to electrically connect with the control unit. And a transmitter for transmitting a signal to the receiver is provided on the front plate of the hood main body.

In the above hood body, the back plate, the top plate, and the left and right side plates are divided into a plurality of members, which can be assembled on site by means of screwing or the like,
The hood member is configured to be detachably assembled to the front opening of the hood member, and the hood member is configured to be fixed to a wall surface or a ceiling surface by using an attachment angle or the like.

Further, the blower unit installed inside the hood main body is a blower equipped with a filter by itself irrespective of the above-mentioned constituent members of the hood main body. , A fan motor and a case that accommodates them and has an opening in the peripheral wall, and a filter is detachably attached to the opening, or the filter is attached to and detached from the suction port of the fan casing without the above case. The blower unit is fixed to the lower surface of the top plate of the hood body by screwing.
The attachment to the top plate is performed by connecting the discharge port of the fan casing of the blower unit to the exhaust port of the top plate.

Furthermore, it is sufficient that the reception section provided in the blower unit and the transmission section provided in the front plate side mutually transmit signals wirelessly, and the medium used for the transmission is an optical medium. (Infrared rays or visible rays may be used), radio waves, ultrasonic waves, and the like. In addition to the receiving section, the blower unit may be provided with a display section (such as lighting of a pilot lamp) for displaying the operating state of the blower unit. In addition, the receiving unit and the control unit equipped in the blower unit may be installed in a separate box integrally on the outside of the case forming the unit and housed inside the box, or in the case forming the blower unit. It may be housed inside.

[0011]

According to the above means, the range hood fan is completed by assembling the hood body while fixing it to the wall surface at the installation site and fixing the blower unit to the lower surface of the top plate of the hood body with screws. . The operation and stop of the blower unit electrically connected to the power supply and the rotation control of the fan are controlled by operating the transmitting unit installed on the front plate side to send a signal to the receiving unit attached to the blower unit. You can

[0012]

As described above in detail, the range hood fan of the present invention has the blower unit attached to and detached from the inside of the disassembleable hood body which is formed by assembling the top plate, the left and right side plates, the front plate and the like, and whose lower surface is opened. It is freely attached, and a control unit and a receiving unit for controlling the operation and stop of the blower are attached to the blower unit, the receiving unit and the control unit are electrically connected, and the reception is performed on the front plate of the hood body. Since the transmitter for transmitting a signal to the unit is provided, it is possible to easily perform installation at the installation site and improve maintainability after installation. Then, the blower unit is turned on and off, the fan rotation is controlled, and the lighting lamp is turned on.
Operations such as turning off the lights are performed wirelessly by the transmitter installed on the front panel and the receiver installed in the blower unit, so there is no need to electrically connect the two via a male / female connector with a cord. There is no need, therefore, there is no work to separate or connect the connector when attaching and detaching the front plate as in the conventional range hood fan, and since there is no cord and connector, a means to protect them from heat. It is very convenient without the need to take.

Further, in the case where the transmitting portion mounted on the front plate side is detachable as in claim 2, if the transmitting portion is detached from the front plate, there is no electric component in the front plate that dislikes moisture. The front plate is water,
It is possible to wash with a detergent etc. and clean every corner cleanly.
