Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air purifier used for ordinary households or business use, and more particularly, to high durability and low cost.

[0002]

2. Description of the Related Art The configuration of a conventional air purifier is shown in FIG.
This will be described with reference to FIG.

An air inlet 10 is provided in an air purifier body 101.
Dust collection filter-102, deodorization filter-
The dust-containing air sucked from the air inlet 106 by the blower fan 104 attached to the motor 105 is purified by passing through both the filters 102 and 103, and is discharged to the outside from the blower port 107. It has a configuration.

[0004]

In the conventional air purifier, the deodorizing filter 103 uses a deodorizing material such as activated carbon. However, it is difficult to regenerate and use activated carbon in ordinary households. Yes, they had to be thrown away and replaced in almost a fixed period of time. For this reason, maintenance costs have been expensive.

An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide a highly durable, low-cost air purifier.

[0006]

In order to achieve the above object, the present invention comprises a deodorizing filter using a room temperature catalyst as a deodorizing filter. The room temperature catalyst decomposes a gas generating odor. It is odorless, has a long-lasting effect with little consumption due to the catalytic effect, and can be kept inexpensive for a long time without consumables.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION
A body having an intake port and an exhaust port has a built-in ventilation fan and a deodorizing filter, and a normal temperature catalyst is used for the deodorizing filter.The normal temperature catalyst decomposes gas generating odor to make it odorless and has a catalytic effect. Thus, there is little wear and the effect is exhibited for a long period of time.

Further, by using a deodorizing filter using a normal temperature catalyst, it is possible to function very effectively as an air purifier which is a device for securing an air environment. That is, the conventional catalyst must be used at a temperature higher than room temperature, and in order to secure an air environment, the air temperature must be reduced, and the energy is extremely increased when the air temperature is increased or decreased. However, the present invention can operate very efficiently without the need to raise or lower the temperature, and can greatly reduce the maintenance cost.

In the invention according to claim 2 of the present invention, a dust collecting filter for collecting dust is provided, and a deodorizing filter is arranged on the lee side of the dust collecting filter. By deodorizing, it is possible to prevent dust from adhering to the surface of the deodorizing material and shortening the life due to clogging and the like, and the effect can be exhibited for a long time without depletion of the deodorizing filter using a normal temperature catalyst.

According to the invention of claim 3 of the present invention, the deodorizing filter is formed by mixing an adsorbent for adsorbing odor and a normal temperature catalyst.
Time, i.e., the contact time of the odor with the catalyst is very short, so that the decomposition ability of the catalyst is insufficient, so that a large amount of the catalyst is required. The catalyst is kept in the adsorbent and comes into contact with the catalyst for a relatively long period of time, and is treated and exhausted. Therefore, a relatively small amount of catalyst is not required in accordance with the peak in the odor fluctuation during use. The effect can be exhibited with the catalyst of (1).

In the invention according to claim 4 of the present invention, since an adsorption filter made of an adsorbent such as activated carbon or zeolite is arranged on the windward side of the deodorizing filter, the odor is temporarily held by the preceding adsorbent filter. By gradually treating the odor with a normal-temperature catalyst deodorizing filter in the subsequent stage, the amount of the catalyst can be averaged without the need for a large amount of catalyst corresponding to the peak in the odor fluctuation during use. Can be demonstrated.

In the invention according to claim 5 of the present invention, the room temperature catalyst used for the deodorizing filter is formed of a compound mainly composed of manganese oxide. And can be manufactured inexpensively as a device.

In the invention according to claim 6 of the present invention, the deodorizing filter is disposed so as to be in contact with the outer shell or the support of the motor for driving the blower fan. Since the temperature rises under the influence of the heat generation of-, the temperature of the room-temperature catalyst also increases by bringing the room-temperature catalyst into contact with this support, while the temperature of the room-temperature catalyst increases as the catalyst reaction speed increases. Since the deodorizing effect increases, the effect can be exhibited with a small amount of catalyst.

According to a seventh aspect of the present invention, since the heat generated from the motor is transmitted to the deodorizing filter through a heat transfer material formed of a material having good heat conductivity such as a metal, the catalyst at room temperature is used. As the temperature rises further, the heat in the bearing portion of the motor is radiated, and the temperature of the bearing portion and the temperature of the motor winding, which determine the life of the motor, can be reduced. The motor can be downsized.

In the invention according to claim 8 of the present invention, the heat transfer material is formed substantially radially around the bearing portion of the motor, so that the heat of the motor can be transferred to the deodorizing filter through the heat transfer material. The effect can be transmitted to many areas, and the effect can be further improved.

According to the ninth aspect of the present invention, a plurality of heat transfer materials are provided, and the air flowing through the air inlet passes between the plurality of heat transfer materials. Since the air is smoothly sucked into the fan portion in a state of low resistance, it is possible to prevent a decrease in the air volume due to the insertion of the heat transfer material.

According to a tenth aspect of the present invention, there is provided a partition for separating a deodorizing filter storage room for storing a deodorizing filter and a room for storing a blower fan, and the heat transfer material is sandwiched between the deodorizing filter and the partition. Accordingly, since the supporting force is shared by the partition walls, the strength of the deodorizing filter using the room temperature catalyst can be reduced, and an inexpensive filter can be used.

According to the eleventh aspect of the present invention, since the deodorizing filter is disposed on the leeward side of the motor, the deodorizing filter is disposed.
The temperature of the air passing through the heater rises under the influence of heat generated by the motor. Therefore, the temperature of the ordinary temperature catalyst also rises. If the temperature of the catalyst rises, the catalytic reaction speed increases and the deodorizing effect increases. Because of the increase, the effect can be exhibited with a small amount of catalyst.

[0053]

According to the first aspect of the present invention,
The sucked air is deodorized by a deodorizing filter that deodorizes odors in the air. Since the deodorizing filter is composed of a deodorizing filter using a normal temperature catalyst, the odor in the air is decomposed and deodorized by the deodorizing filter, so it has a deodorizing capacity like activated carbon deodorizing and cannot collect more than a certain amount. Without that, it can be semi-permanently deodorized.

Further, by using a deodorizing filter using a normal temperature catalyst, it is possible to function very effectively as an air purifier which is a device for securing an air environment.
That is, the conventional catalyst must be used at a temperature higher than room temperature, and in order to secure an air environment, the air temperature must be reduced to room temperature, and the air temperature must be increased or decreased. Although energy efficiency was poor, the present invention can operate very efficiently without the need to raise or lower the temperature, and can result in a significant reduction in maintenance costs.

According to the second aspect of the present invention, dust in the air sucked in can be removed before the deodorizing filter, and adheres to the conventional deodorizing filter to reduce the catalytic effect. Dust, especially tobacco smoke, etc.
The effect of the room-temperature catalyst can be stably maintained for a long period of time by collecting the catalyst components.

According to the third aspect of the present invention, since the deodorizing filter is constituted by mixing the adsorbent and the normal temperature catalyst, the time required for the odor to pass through the deodorizing filter only with the ability of the catalyst, that is, the odor. Because the contact time with the catalyst is very short, the decomposition capacity of the catalyst is insufficient, so a large amount of catalyst is required.However, by disposing the adsorbent in the vicinity, the odor is temporarily held by the adsorbent and is relatively long Contact with the catalyst for a period of time, which will be treated and exhausted, so that a relatively small amount of catalyst is effective without the need for a large amount of catalyst in accordance with the peak in the odor fluctuation during use. Can be.

According to the fourth aspect of the present invention, an adsorbent filter made of an adsorbent such as activated carbon, zeolite or the like is disposed in front of the deodorizing filter, so that the odor is temporarily absorbed in the front stage. The odor is held by a material filter and the odor is gradually treated by a normal temperature catalyst deodorizing filter at a later stage. As a result, the effect can be exhibited with the averaged amount of the catalyst without requiring a large amount of the catalyst in accordance with the peak of the odor variation during use.

According to the fifth aspect of the present invention, since the ordinary temperature catalyst of the deodorizing filter is composed of a compound mainly composed of manganese oxide, the use of manganese oxide as the ordinary temperature catalyst allows industrial comparison. It can be obtained at low cost and can be manufactured at low cost as a device.

According to the invention of claim 6 of the present invention, the deodorizing filter to which the room temperature catalyst has been added is disposed so as to be in contact with the support of the motor for driving the blower fan. Since the temperature of the support of the heater is rising due to the heat generated by the motor, the temperature of the normal temperature catalyst also increases by bringing the deodorizing filter having the normal temperature catalyst into contact with this support. When the temperature of the room temperature catalyst rises, the catalytic reaction speed increases and the deodorizing effect increases, so that the effect can be exhibited with a small amount of catalyst.

According to the seventh aspect of the present invention, the heat of the bearing portion of the motor is transmitted to the deodorizing filter via the heat transfer material made of a material having good heat conductivity such as metal. Therefore, the temperature of the room temperature catalyst also rises, and the heat of the bearing portion of the motor is radiated, so that the temperature of the bearing portion which determines the life of the motor and the temperature of the motor winding are reduced. And the motor can be downsized.

According to the eighth aspect of the present invention, since the heat transfer material is formed so as to spread substantially radially around the bearing portion of the motor, the heat of the motor is transferred. It can be transmitted to a larger area of the deodorizing filter through the material, and the effect can be further improved.

According to the ninth aspect of the present invention, air is passed between a plurality of heat transfer members which are formed so as to extend substantially radially in a branch shape toward the motor side suction port. By doing so, the air that has passed through the room-temperature catalyst of the deodorizing filter is smoothly sucked into the fan portion with low resistance, so that stable operation can be performed without a decrease in air volume due to insertion of the heat transfer material.

According to the tenth aspect of the present invention,
Since a plurality of heat transfer materials configured so as to be substantially radially spread in a branch shape are sandwiched between the deodorizing filter using the room temperature catalyst and the partition wall, the deodorizing filter using the room temperature catalyst that receives the pressure of the passing wind is used. In order to support a plurality of heat transfer materials, it is necessary that the plurality of branch heat transfer materials have high strength. However, as in the present invention, a plurality of heat transfer materials are interposed between the deodorizing filter using the room temperature catalyst and the partition. Since the supporting force is also shared by the partition walls, the strength of the deodorizing filter using the room temperature catalyst can be reduced, and an inexpensive filter can be used.

According to the eleventh aspect of the present invention,
Since the deodorizing filter using the normal temperature catalyst is disposed downstream of the motor driving the blower fan, the temperature of the air passing through the motor increases due to the heat generated by the motor. Therefore, the temperature of the deodorizing filter using the ordinary temperature catalyst also increases. If the temperature of the catalyst increases, the catalytic reaction speed increases and the deodorizing effect increases, so that the effect can be exhibited with a small amount of catalyst.

As described above, according to the present invention, a conventional apparatus can be solved with a simple device, and a highly durable and low-cost air purifier can be provided.
