Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a forced air supply / exhaust type floor-mounted hot air heater provided with a humidifying device.

[0002]

2. Description of the Related Art Conventional floor-installed forced air supply / exhaust type hot air heaters are disclosed, for example, in Japanese Utility Model Publication No. 54-170663, Japanese Utility Model Publication No. 56-148527, and Japanese Utility Model Publication No. 57-1.
No. 09427, Japanese Utility Model Laid-Open No. 60-125434,
The structure is as disclosed in Japanese Utility Model Laid-Open No. 63-1338. That is, a warm air passage having one end connected to the indoor air inlet and the other end connected to the warm air outlet is formed in the main body, and a convection blower, a closed combustion combustion device, and a heat exchanger are arranged in this warm air passage. It is set up. In the combustion device, combustion air is supplied from the outside by an air supply system, and combustion waste gas is exhausted to the outside by an exhaust system connected to the rear end of the heat exchanger. The convection blower forms a flow of indoor air in the warm air passage, and causes the indoor air sucked from the indoor air suction port to come into contact with the heat exchanger and blow out as warm air from the warm air outlet to the room. And, as shown in the above-mentioned publication, many of this kind of heaters incorporate a humidifier in order to improve the indoor heating environment. As the humidifier, for example, an evaporation dish that stores water is provided on the bottom side of the main body, and a part of the warm air is introduced into the evaporation dish.

The conventional hot-air heater having the above structure can obtain a clean heating atmosphere without polluting the indoor air with the combustion waste gas, and the one equipped with the humidifier humidifies a part of the warm air. The humidified air can be blown out into the room together with the warm air to prevent the room from drying.

[0004]

In the conventional forced air supply / exhaust type floor-installed type hot air heater as described above, related parts for air supply / exhaust are piped from the main body to the outside, and thereby the main body Since the installation location is fixed, the main body only has legs on the bottom. Therefore, directly below the bottom of the main unit is the floor structure such as tatami mats and carpets in the room as it is, and in the type with a humidifier at the bottom of the main unit, wet the floor structure at the installation site with water, It sometimes caused discoloration of the surface. That is, when replenishing the water of the humidifier, water is spilled or warm air for humidification is blown directly to the bottom side of the main body due to forgetting to attach the evaporation tray, and the bottom side of the main body is heated and the floor structure below it is heated. May cause discoloration on the surface.

An object of the present invention is to obtain a forced air supply / exhaust type floor-installed warm air heater that does not cause inconvenience to the floor at the installation site even if water for humidification is spilled or the evaporation tray is forgotten to be attached. And

[0006]

A hot-air heater according to the present invention introduces a part of warm air to a lower part of a main body equipped with a closed combustion type combustion device and a convection blower to humidify and warm the hot air. In addition, a humidifier for supplying indoors is provided, and the whole is fixed on a base formed in a flat-bottom dish shape wider than the projection plane of the main body.

[0007]

In the hot air heater according to the present invention, even if water overflows when supplying water to the humidifier, it only overflows on the base, and the surface of the floor structure at the installation site does not get wet. Also, if you forget to remove a part of it by cleaning the humidifier, etc., even if the bottom side of the main body is heated by warm air for humidification, the heat is blocked by the base, so the surface of the floor structure below it discolors due to burns. Will not occur.

1 is a side sectional view of a warm air heater showing an embodiment of the present invention. This hot air heater is a forced air supply / exhaust type floor installation type equipped with a humidifier, and the functional components related to heating are basically the same as those of the conventional type. That is,
Inside the main body 1, a warm air passage is formed, one end of which is connected to an indoor air intake port 2 provided on the back surface of the main body 1 and the other end of which is connected to a warm air outlet 3 provided on the lower front surface of the main body 1. A convection blower 4, a closed combustion type combustion device 5 and a heat exchanger 6 are arranged in the warm air passage. In the combustion device 5, combustion air is supplied from the outside by an air supply system (not shown), and combustion waste gas is exhausted to the outside by an exhaust system (not shown) connected to the rear end of the heat exchanger 6. The convection blower 4 forms a flow of indoor air in the warm air passage, contacts the indoor air sucked from the indoor air suction port 2 with the heat exchanger 6, and blows it out from the warm air outlet 3 into the room as warm air. On the bottom side of the main body 1, a humidifier for incorporating a part of warm air after heat exchange into the water collected in the evaporation tray 7 by a warm air guide to humidify the warm air is incorporated. The humidifier is composed of an evaporation tray 7 which is attached to the bottom side of the main body 1 so as to be removable from the front surface, and a cartridge tank 8 which supplies water to the evaporation tray 7. Legs 9 for installation are attached to the left and right sides of the bottom surface of the main body 1, and the whole is fixed on a base 10 formed in a flat-bottomed dish shape wider than the projection plane of the main body 1.

The hot air heater of the above construction is of a floor installation type, and it can be heated by hot air by deciding the installation place and connecting the relevant parts for air supply and exhaust from the main body 1 to the outside. At the time of installation, since the whole is mounted on the base 10, it can be easily moved to the installation place by sliding the floor without lifting the whole, and the stability is high even when the installation place is not flat. In replenishing the humidifier with water and cleaning the evaporation tray 7, the surface of the floor structure such as tatami or carpet is not wet by the base 10 even if water overflows. Further, even if the heating operation is performed without forgetting to attach the evaporation tray 7, the heat due to the warm air for humidification is blocked by the base 10, so that the trouble that the surface of the tatami mat, the carpet or the like is discolored by the heat is avoided. ..

[0010]

As is apparent from the above description of the embodiments, according to the present invention, even if water overflows when supplying water to the humidifier, it only overflows on the base, and the surface of the floor structure at the installation site is It is not necessary to wet it, and even if you forget to attach the evaporation tray without removing it, the heat from the warm air for humidification is blocked by the base, so the surface of the floor structure below it will not discolor.
