Abstract

PROBLEM TO BE SOLVED: To make a warm air heating system compact in size by reducing the dead space in a composite machine. SOLUTION: The depth of the warm air heating system and, at the same time, the dead space in front of a warm air heating section having a smaller depth than an air cleaning section has are reduced by positioning an air cleaning filter 16 below an air cleaning fan 15. In addition, in order to take out the filter 16 through a filter taking-out port 23 on the back of the system, an air inlet for cleaning air provided on the front side of the furnace is constituted in a fixed type. Since the filter taking-out port 23 is on the back side of the system, a simple attaching method using such a manual screw that is not able to be used on the front side of the system from the viewpoint of appearance can be adopted.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot air heating device provided with an air purifier.

[0002]

2. Description of the Related Art Conventionally, this type of warm air heating apparatus with an air purifier is generally the one described in Japanese Patent Application Laid-Open No. 11-118255.

As shown in FIG. 5, this apparatus comprises a burner 1 for burning supplied gas, a combustion chamber 2 for mixing exhaust gas and air, and a convection filter 4 provided at the rear of a device for sucking outside air 3. Below the burner 1, there is a hot air heating section composed of a convection fan 6 for sending out hot air 5 and a hot air outlet 7 provided in front thereof.

In the upper part of the warm air heating section, an air purifying suction port 9 provided in front of the device for sucking the outside air 8 and a maximum surface for suction inside the air purifying fan 10 inside and in front of the air purifying fan 10 for sending out air. There is an air purifying unit composed of an air purifying filter 11 provided so that the front side is located in front of the air purifier and an air purifying outlet 12 provided above the appliance.

Next, the operation will be described. In the hot air heating section, the high-temperature exhaust gas 13 generated by burning the gas in the burner 1 by the rotation of the convection fan 6 and the convection air 3a taken in from the convection filter 4 are fed into the combustion air passage 14 of the combustion chamber 2. And sent out as hot air 5 through the hot air outlet 7.

In the air purifying section, the outside air 8 is sucked in from the air purifying inlet 9 by the rotation of the air purifying fan 10, and dust and odor are removed by the air purifying filter 11, and the air is discharged from the air purifying outlet 12. Clean air 8a is delivered.

Since the air purifying filter 11 is replaceable, the air purifying filter 11 can be removed toward the front while removing the air purifying suction port 12 in front of the instrument.

[0008]

However, in the configuration of the above-described conventional warm air heating device with an air purifier, the air purifying filter of the air purifying section is provided in front of the air purifying fan, and the air purifying suction port is provided in front of the air purifying fan. , The depth of the appliance is increased, while the warm air heating section below the air purifying section does not require that much depth, so an unnecessary space must be provided in front of the combustion chamber. did not become.

In addition, since the outside air is sucked into the air purifying section in one direction, there is a slightly dull surface when a large room or equipment is installed in the center of the room.

Further, as a method of taking out the air purifying filter when replacing the air purifying filter, first, the air purifying suction port having a size close to about half of the front of the appliance is removed. It was very difficult to adjust the sensitivity, such as the hook method, which emphasized the gap fitting adjustment and the ease of attachment and detachment, and it was necessary to finish with trial and error.

When the air purifying filter is removed,
In order to ensure safety, such as preventing a user from touching internal components of the air purifying section, it was necessary to add components such as a cover.

A major factor that lowers the air purification performance of the air purifying section is air leakage in the air passage. Particularly, the leakage from the surroundings where the air purifying filter is provided is the largest. However, it was difficult to improve the air cleaning performance.

[0013]

According to the present invention, in order to solve the above-mentioned problems, an air purifying filter of an air purifying section is provided below an air purifying fan so that a maximum suction surface is horizontal. It is.

According to the above invention, the depth of the appliance can be reduced, the unnecessary space of the hot air heating unit below the air purifying unit can be reduced, and the appliance can be reduced in size. Becomes

Further, by providing the air purifying suction ports of the air purifying section not only on the front surface but also on both side surfaces and the rear surface, outside air can be sucked from all directions in the room, and the air purifying operation can be performed efficiently.

Further, by adopting a configuration in which the air purifying filter of the air purifying section is taken out from the rear side of the appliance, the air purifying suction port on the front surface of the appliance, which emphasizes the external appearance, is fixed so that it cannot be detached, and the air behind the appliance is inconspicuous. A door is provided as an outlet for the filter for cleaning, and a configuration that emphasizes gap fitting such as manual screws that are difficult to use in appearance is adopted.

Further, by attaching the air purifying filter of the air purifying section to a filter frame having a rail system, air leakage can be reduced, and the air purifying performance can be improved.

[0018]

[0040]

As described above, according to the present invention, since the air purifying filter of the air purifying section is provided below the air purifying fan, the depth of the appliance is reduced, and one of the hot air heating sections is provided. Unnecessary space in front of the combustion chamber can be reduced, and the apparatus can be made more compact.

In addition, depending on the component configuration, the depth of the unnecessary space in front of the combustion chamber is not located at the hot air outlet, so that it may be connected with another component, but this connection component can be reduced.

Further, since the air purifying suction ports of the air purifying section are provided not only on the front surface but also on both side surfaces and the rear surface,
Outside air can be sucked in from all directions in the room, and this promotes air circulation in the room, thereby enabling the air in the room to be efficiently purified.

Further, since the air purifying filter of the air purifying section is taken out from the rear side of the appliance, it is possible to reduce the necessity of adjusting the fitting of the clearance around the air purifying suction port and the removability by emphasizing the appearance. If a hook or the like is used as a detaching method in consideration of the appearance, the number of components can be reduced.

Further, since the air purifying filter of the air purifying section is mounted on the filter frame having the rail system, the amount of air leak due to the gap between the air passage and the air purifying filter can be reduced by the overlap of the rails, and the air purifying can be performed. Performance can be improved.
