Description

[Detailed description of the invention] The present invention relates to a hot air heater that is equipped with a heat source consisting of a gas or oil burner inside the exterior body and a blower that brings air into contact with the heat source and takes out the hot air. This makes it possible to easily and reliably clean the dust.

Conventionally, as shown in FIG. 1, a fan case 1 is provided with a cleaning port 2, and a lid 3 is attached to the cleaning port 2. When cleaning, the front surface of the exterior body 4 is first opened. Remove the panel and then use this lid 3.
It was removed to expose a cleaning port 2, and the tip of a suction pipe 5 of a vacuum cleaner commonly used at home was inserted through the cleaning port 2 to suck up dust attached to the white dust fan 6.

However, since the spacing between the blades of the Shirotsuko fan 6 is very narrow, it is difficult to suck the dust off the blades.Furthermore, the dust attached to the blades is removed with a toothbrush, etc., and dropped to the inner bottom of the fan case 1, and then sucked in with a vacuum cleaner, but the suction pipe 5 is removed from the fan case. It was not possible to penetrate to the inner bottom, and as a result, the suction remained and the dust was released into the room during the next operation.If the heat source was a combustor, dust was generated and sparks were released from the outlet, creating a risk of fire. In addition, in the case of a so-called bottom-blowing hot air heater in which the fan case 1 is located above the heat source and the hot air outlet is located below, the air outlet is opened at the bottom of the fan case 1, so that the blades When dust is removed with a brush, it scatters into the exterior body 4 from this discharge port, making cleaning even more difficult.

The present invention was devised to solve the above-mentioned drawbacks, and will be explained below with reference to FIGS. 2 and 3. 7
is an exterior body equipped with a front panel 9 having an air outlet 8 at the bottom, and a cartridge tank 1 in the internal right space.
0, a fuel supply mechanism A consisting of an oil receiver 11 that is supplied with oil from the tank, a pump 13 that sends oil from the oil receiver 11 to a burner section 12 (described later), etc. is installed, and the lower left space inside the exterior body 7 is equipped with the above-mentioned A heat source B consisting of a combustion chamber 14 and a burner section 12 corresponds to the air outlet 8.
is installed. Furthermore, in the left upper space inside the exterior body 7, the air taken in from the suction port 15 provided on the back surface of the exterior body 7 is accelerated and brought into contact with the heat source B, and the air is drawn into the air outlet 8.
A blower C that emits warm air is installed.

The blower C includes a motor 16 and a fan case 1.
7. A sirotsko fan 19 fixed to the rotating shaft 16' of the motor 16 with a mounting member 18 such as a nut in the fan case 17, and a donut-shaped fan case nozzle removably attached to the openings at both ends of the fan case 17 with screws 20. It is composed of 21 mag. Reference numeral 22 denotes an opening formed in a side plate of the exterior body 7 that faces the axial direction of the Shirotsuko fan 19, and this opening 22 is sized to allow the Shirotsuko fan 19 and the fan case nozzle 21 to be inserted therethrough. 23
locks the lower end locking piece 23' to the inner wall of the lower edge of the opening 22,
This is a blind plate that covers an opening whose upper part is removably fixed to the exterior body 7 with screws 24.

When cleaning the blower C, the blank plate 23
Then, remove the fan case nozzle 21 from the fan case and the Siroco fan 19 from the motor shaft 1.
It is removed from 6' and pulled out to the outside of the exterior body 7 through the opening 22, and cleaning is carried out in a place separate from the warm air heater.
Dust adhering to the inside of the fan case 17 is removed by passing the suction pipe of the vacuum cleaner through the opening 22 of the fan case 17.
7, or insert it into the fan case 1 as in the past.
This is done through a cleaning port 24 provided on the front surface of the chamber 7. This cleaning port is not essential, but if provided, it is usually fitted with a lid 25.

As described above, the present invention makes it possible to easily and reliably clean dust from a cleaning fan, and also eliminates the drawbacks of the conventional cleaning method.
