Abstract

PURPOSE:To easily kill injurious microbes such as ticks by building a temperature raising means in a vacuum cleaner body to heat intake passing through an intake port to a dust chamber so that the temperature in the dust chamber is at least 50 deg.C. CONSTITUTION:To kill ticks or the like in dust after collecting dust by starting a motor blower 22, a dust collecting hose 40 is withdrawn from an intake port 25 to close the intake port 25 with a shutter 26. Thus, a rib 28 changes over switches 30, 31 of a change-over device 29 to start running of the motor blower 22 through a resistance 43 with low speed and supply current to a heater 39. The intake port 25 is closed with the shutter 26 and a hot air discharge port 37 is opened, so that air is taken in from an intake port 35, warmed to at least 50 deg.C by the heater 39, sent from the hot air discharge port 37 through a dust collecting port 36 into a dust chamber 23 and expelled out of an exhaust port 24. The temperature in the dust chamber 23 is successively raised so that injurious microbes such as ticks in dust are killed in several minutes.

From Ss! This is a dust collection hose that is connected to penetrate to the back door, and there is a pipe at the other end of this dust collection hose.

Floor brushes are connected sequentially. (4υ is the board that electrically connects the heater (to) 1 manual return thermostand q, switching bed, #1 of the It effect blower, (43 is the Il!! dust hose [provided in the hand-held part of 40) The power control switch (c) is a resistor for low-speed operation of the active air blower mounted on the υ side of the board.Also, the arrows indicate the air flow.

Next, the operation will be explained.

First, in order to clean, as shown in Figure 3, step 11! Insert the exhaust hose T411 from the inlet to the dust collection port, and slide the power control switch Q3 attached to the #kIII hose F41.

The electric blower starts at 1°C, and the floor brush (not shown) generates intense suction, which sucks up dust on the floor and carpet, and traps it in the dust collection chamber opening.5 Next, dust mites in this trapped dust In order to kill harmful microorganisms such as・1 switch 1.L:
As shown in FIG. 2, switch 311 is switched to switch C1, and switch Lsv is switched to C3. As a result, the electric blower device starts operating at a low speed due to the resistor (43), and the heater (to) is also turned on.

The inside of the suction port is closed by the shutter ~, and the hot air discharge port (
9) is closed to the shoulder, so air is taken in from the intake port. This inhaled air is heated to over 50 degrees Celsius by the heater (total), and it is 1 from the duck-style outlet punishment! It flows into the dust collection chamber through the mouth mold, and then escapes from the electric blower to the exhaust port. As a result, the inside of the IK dust chamber 1 is gradually increased in concentration, and harmful microorganisms such as mites in the dust are killed after separation.

As the electric current in the dust collection chamber 1 increases, the temperature near the heat sensitive part (33a) of the hand-operated turbidity thermostat η, which is used upstream of it, also rises, and the heat sensitive part (53a) senses the predetermined temperature of 4 degrees. Then, turn on the circuit (1) to turn on the electricity, and once the killing of harmful microorganisms such as mites is complete, clean the air and put it away in a corner of the bay or in a closet.

Just to clean again the next day, close the hot air outlet ■ with the shutter, open the suction port, and insert the dust collection hose [4 (1) into this suction port. When the return switch (B) of the thermostat (G) is pressed and reset, one circuit closes and energization becomes possible. Also, the rib (to) switches the switch 1.Gυ of the beak 1. As shown in Figure 4, switch j enters 02 and switch Gυ enters C4.This causes the dust collection hose (411 to be connected to You can start it up and clean it.

With the above configuration, the air passage structure and circuit 'l: for killing harmful microorganisms such as mites are created by the closing/closing operation of the shutter 1, so that the operation can be performed very easily. Also, switching equipment? 1 to the l"l and hand @ return thermostat 4 is not output to the α moving vacuum cleaner body (1), so there is no need to worry about it being tampered with, and the SL is also beautifully organized. Also, when cleaning, the shutter and the controller do not discharge hot air. Since the outlet Cη is blocked, if the dust collection hose (41t) is not used for dust collection, normally the intake air will be from the intake port Ca and the dust collection port (to) will be closed.
This prevents dust from building up on the top surface.
