Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to an appliance that has an air purifying function built into its main body.

<Prior art> Conventionally, in this type of appliance, the outlet for taking out the dust collection unit for cleaning, etc., and the handle used for moving the appliance, etc., have been formed separately at appropriate locations on the appliance body. It had been.

<Problems that the invention aims to solve> By the way, in this conventional device, as mentioned above, the outlet and the handle were formed separately on the main body of the device, which made the molding process cumbersome and time-consuming, which made it expensive. It was hot.

<Means for Solving the Problems> This invention focuses on this point, and in order to solve the above-mentioned drawbacks, the structure is particularly modified such that the device body 1 has an outlet for taking out the dust collection unit 14 at a proper place, and an outlet for taking out the dust collection unit 14. It is provided with a handle 13 which also serves as a handle for carrying.

<Function> Dust collection unit 1
If a large amount of floating matter adheres to the device 4 and it needs to be cleaned, the dust collection unit 14 can be removed from the outlet/handle 13 and cleaned. It can be easily carried by hand,
Since the ejection opening and the handle are both used, one molding is required instead of two separate moldings, and molding is extremely simple and inexpensive.

<Example> Next, a device with a built-in air purifying function according to this invention will be described with reference to a preferred example shown in the drawings.

Reference numeral 1 denotes a main body of the apparatus, which is partitioned from the inside by a partition plate 2 and equipped with a cartridge-type fuel tank 3 on one side, and the upper end of a combustion burner 4 is exposed below the center on the other side. A combustion chamber 5 is partitioned by a partition plate 6.

Reference numeral 7 denotes a cylindrical combustion tube that covers the combustion burner 4 within the combustion chamber 5, and its upper end is closed with a catalyst body 8 that purifies the combustion gas.

Reference numeral 9 denotes a warm air fan provided protruding from the back of the appliance main body 1 behind the combustion chamber 5. When driven, indoor air is drawn in through the cover body 10, and the combustion gas generated by combustion in the combustion burner 4 is sucked out. The mixture is mixed with hot air and discharged as warm air from the air outlet 11 formed at the lower front of the device body 1.

Reference numeral 12 denotes an inverted L-shaped air cleaning chamber provided in the space between the upper part of the combustion chamber 5 and the appliance body 1, which can be freely entered and exited from the outlet/handle 13 formed on the side of the appliance body 1 above the combustion chamber 5. A dust collection unit 14 is attached, and the upper part has a function chamber 16 having a discharge port 15 that protrudes from the top surface of the appliance main body 1 and has an opening. It is constituted by a blowing fan 18 communicating with the functional chamber 16 so as to suck indoor air through a formed suction port 17 and blow the air into the functional chamber 16.

The dust collection unit 14 is plate-shaped and has a square hole 14 with a side of about 15 mm in a discharge counter electrode 14a connected to a positive power source.
A dust collection pole piece 14c is provided with a plurality of regular openings in b, one side of which is bent toward the downstream side, and a discharge electrode 1 is connected to a negative power source in a needle shape from the back side of the dust collection pole piece 14c.
4d is positioned toward the center of each square hole 14b.

In addition, when the dust collection unit 14 is energized, a voltage of approximately 7kV DC boosted by a transformer (not shown) is loaded (negative discharge) between the discharge counter electrode 14a and the discharge electrode 14d, and fine dust and cigarettes in the air are collected. Floating objects such as smoke, bad odor, and dust mites are charged and attracted and adsorbed to each dust collection pole piece 14c.

The ejection opening/handle 13 has a horizontally long rectangular shape and is fixed to the dust collection unit 14 from one side, and includes a knob portion 19 that serves as a handle when taking out the dust collection unit 14, and a hand can be inserted into the other side. A gap is formed between the handles 20 and 20 formed on the opposite side of the instrument body 1, and the instrument body 1 is carried by hanging the hand thereon.

Reference numeral 21 denotes a filter device detachably attached to the suction port 17 of the blower fan 18, which is equipped with a net-like filter or the like to remove large cotton dust and the like from the air.

A combustion fan 22 supplies combustion air to the combustion burner 4, and supplies indoor air sucked through an opening 23 to the combustion burner 4 via an air passage 24.

25 is a metering tank that temporarily receives fuel from the fuel tank 3, and the fuel pipe 2 is equipped with a solenoid valve 26 in the middle.
7 to supply fuel to the combustion burner 4.

Reference numeral 28 is an opening/closing lid for entering and exiting the fuel tank 3. Next, the operation of this embodiment will be explained.

If a large amount of fine dust has adhered to the dust collection unit 14 due to the air cleaning operation for a long time and cleaning is necessary, use the knob 19 exposed on one side of the outlet/handle 13. By pulling the handle forward, the dust collection unit 14 can be easily taken out from the outlet/handle 13 as shown in Fig. 4, and after cleaning such as washing with water, it can be returned to its original position, making cleaning extremely easy. be.

When carrying the instrument body 1, place one hand on the open part of the outlet/handle 13 opposite to the knob 19, and place the other hand on the handle 20 provided on the opposite side of the instrument body 1. Put your hand on it,
By lifting and moving the instrument main body 1, the instrument main body 1 can be carried without any change from conventional methods.

Therefore, by using a single outlet and handle 13 as the outlet for taking out the dust collection unit 14 and the handle for carrying the instrument body 1, it is possible to use only one part instead of molding the two parts individually. It is extremely simple and can be manufactured at low cost.

Furthermore, since only one outlet and handle are required, which open outward from the instrument main body 1, there is less risk of the air blown by the blower fan 18 leaking out of the instrument, and the airtight structure requires only the outlet and handle 13. It is easy to use, has a simple structure, and is highly safe.

<Effects of the invention> In short, this invention houses a blower fan 18 for blowing air and a dust collection unit 14 that removes floating matter such as dust, smoke, and mites in the air in the device body 1. The device body 1 is provided with an outlet/handle 13 at a suitable location for taking out the dust collection unit 14 and a handle for carrying the device body 1. There is no need to provide separate handles for carrying the spout and the main body of the instrument, and one handle can be used for both purposes, making it convenient to handle, and also extremely easy to mold and can be manufactured at low cost.
