Description

  The present invention relates to a hot air heater provided with a suction port at the upper back and a hot air outlet at the lower front, and more particularly, to a structure in which a heat exchanger can be easily attached and detached through the suction port. .

  As shown in FIGS. 3 and 4, the conventional hot air heater has a suction port 1 provided at the upper part of the back face and opposed to the filter 9 and the suction grill 10, and a blow-off grill 2 a provided at the lower part of the front face. A heat exchanger 3 connected to a connection hose 3a and a blower fan 4 covered by a back plate 6 are provided in an air passage connecting the hot air outlet 2 and the heat exchanged heat by the heat exchanger 3 is provided. The wind was blown out from the hot air outlet 2 along the floor.

  For example, when dust in the air sucked from the suction port 1 adheres, the heat exchanger 3 is periodically cleaned because the ventilation resistance increases or the heat exchange efficiency decreases. In this case, since it is not configured to have a dew tray like an air conditioner, for example, it is cleaned by taking it out.

  Further, since it is necessary to take out or attach the heat exchanger 3 to the outside during maintenance or replacement, it has been desired that the heat exchanger 3 can be easily attached and detached.

  However, after the heat exchanger 3 removes the front panel 7 (and the top / side cover 8 etc.) provided with the hot air outlet 2, the heat shield plate 5, the blower fan 4, the fan motor 4 a, etc. Since it has a configuration that cannot be taken out unless it is removed, workability is poor and inconvenient.

  Alternatively, as a conventional hot air heater, a hot air blower for blowing hot air to the outside and a surface of the front panel that is outside the hot air outlet provided in the hot air fan are detachable for heating via a magnet. The thing provided with the heat exchange unit was disclosed (for example, refer patent document 1).

  In this case, the heat exchange unit is not configured to be taken out from the inside of the hot air heater and easily cleaned, and can be easily attached to and detached from the surface of the front panel on the outside of the hot air outlet. Since it is configured so that it protrudes outside the warm air fan, it has the disadvantage that the protruding part gets in the way or looks bad It was.

  In addition, a heat exchanger is provided inside the warm air machine. For example, the heat exchanger can be easily attached / detached without removing the blower fan, thereby improving the cleaning performance and maintainability. The configuration for making it happen was not disclosed.

  According to the present invention, the heat exchanger is configured so that it can be easily attached and detached through the suction port provided in the upper back portion, so that the cleaning property and maintainability of the heat exchanger can be improved. Hot air heater can be provided.

Embodiments of the present invention will be described below in detail as examples based on the accompanying drawings.
FIG. 1 is a sectional view of a hot air heater according to the present invention, and FIG. 2 is an exploded perspective view of the hot air heater according to the present invention.

  As shown in the figure, the hot air heater according to the present invention has an air passage in the main body that connects a suction port 1 provided at the upper part of the back surface and a hot air outlet 2 provided at the lower part of the front surface. The heat exchanger 3 supported by the heat exchanger support part provided with the fixing means fixed from the side and the blower fan 4 linked to the fan motor are provided, and the indoor air sucked from the suction port 1 is the heat After heat exchange in the exchanger 3, the blower fan 4 blows out the hot air outlet 2.

  A heat shield plate 5 is provided between the front portion of the heat exchanger 3 and the front panel 7, and the blower fan 4 linked to the fan motor is supported by a support member 4 a and the back side is a back plate 6. Covered by.

  A blowing grill 2a is detachably attached to the hot air outlet 2, and a filter 9 and a suction grill 10 are detachably attached to the back of the heat exchanger 3, respectively.

  The heat exchanger support part is composed of the heat shield plate 5 and the back plate 6, and the heat exchanger 3 includes the heat shield plate 5 and the back plate 6 as shown in FIG. The heat exchanger 3 can be easily and accurately supported by supporting the upper and lower portions, and the suction port 1 can be opened widely to move back and forth. Yes.

  At that time, the pipe led out from the heat exchanger 3 and connected to the connection hose 3a can move back and forth along a through hole d provided in the heat shield plate 5 or the back plate 6 and opened rearward. Thus, when the heat exchanger 3 is mounted, it is covered by the piping cover 11 together with the connection hose 3a.

  Further, when removing the heat exchanger 3, the connection hose 3a may be removed from a hot water outlet (not shown) connected to the tip of the connection hose 3a.

  For example, when a thermal valve (not shown) is used, the connection hose 3a may be removed from the connection portion with the pipe on the heat exchanger 3 side.

  As a result, the heat exchanger 3 can be easily detached from the suction port 1 as shown by arrows A and B in FIG. 1 after sequentially removing the suction grill 10 and the filter 9. Workability is improved.

  Therefore, for example, when the heat exchanger 3 is to be removed or removed from the hot air heater for maintenance, the suction grille is removed without removing main components such as the blower fan 4 and the fan motor. By removing 10 and the filter 9, it can be easily removed through the suction port 1 or can be easily attached.

  When the heat exchanger 3 is attached, the heat exchanger 3 may be inserted from the suction port 1 and attached from the suction port 1 side by a fixing means for fixing the heat exchanger 3.
