Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a carpet maintenance device, and in particular, it is used to kill and sterilize mites and mold living in carpets, and to suppress their proliferation, and to prevent the raising of carpet piles. This is what we aim to do.

Conventional technology Conventionally, this type of carpet maintenance equipment is
The structure was as shown in the figure.

That is, 1 is a main body, and 2 is a vaporization chamber that includes a heater 3 and forms a first vaporization chamber 5 and a second vaporization chamber 6, which are thermally communicated inside and provided with a hole 4 through which steam is communicated. ,7
1 above. 8 is a temperature controller (for example, a thermostat) that sets the second vaporization chamber 6.6 to the optimum temperature for vaporization, and 8 is the second vaporization chamber 6.
This is a steam outlet for discharging the steam generated in the vaporization chamber 6, and these are collectively referred to as a steam generator.

Next, 9 is a pile of carpet, and 1o is a nozzle portion for guiding the steam into the pile 9 and ejecting it. Further, 11 is a water supply tank, and 12 is a water supply pump that pressurizes and supplies water from the water supply tank 11 to the steam generator via a water distribution pipe 13.

On the other hand, 14 is a drivable rotary brush 1 held at both ends.
5 and a drive motor interlocked by a belt 16,
17 is a brush case that covers the rotating brush. 18
1 is a moving piece attached to the main body 1 so as to be interlocked with the main body 1, and 19 is an operation frame attached to the main body 1. Further, FIG. 3 shows the inside of the second vaporization chamber 6 and the distribution of ejected steam in a conventional example.

Problems to be Solved by the Invention However, with such a configuration, the steam generated in the first vaporization chamber 6 is at a very high pressure, and is ejected through the hole 4 into the second vaporization chamber 6, causing the steam to flow through the nozzle section. It collided with the floor surface at an angle of 1°, and the third
Run to both sides as shown. At this time, there was a problem in that the steam ran sideways at the entrance of the steam outlet 8 at the lower part of the hole 4, and the steam was not blown out to the outside, so that the mite-killing and fluff-raising effects in this area were greatly deteriorated.

Therefore, the present invention aims to eliminate the difference in the steam ejected from each steam outlet, and to obtain stable mite-killing and hair-raising effects without variations.

Means for solving the problems and the technical means of the present invention for solving the above problems are to provide a small chamber with a partially open area at the bottom of the hole.

action The effect of this technical means is as follows.

That is, the steam generated in the first vaporization chamber passes through the hole and is ejected into the second vaporization chamber. At this time, the steam that collides with the floor is moderately prevented from traveling sideways by the small chamber provided at the bottom of the hole, and is pressurized within this small chamber, resulting in steam flowing from the steam outlet at the bottom of the hole. will be ejected.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

In Figure 1.2, 25 is the main body, 26 is the heater 27
This is a vaporization chamber that forms a first vaporization chamber 29 and a second vaporization chamber 30, which are thermally communicated with each other and are provided with a hole 28 for communicating steam, and 31 is provided in the second vaporization chamber 3o. 32 is a small room with one part opened. 33 is a temperature controller (for example, a thermostat) that sets the second vaporization chamber 29°30 to the optimum temperature for vaporization;
These are multiple steam outlets for spouting out the steam generated in the steam generator, and these are collectively called a steam generator.

Next, 34 is a carpet pile, and 36 is a nozzle portion for guiding the steam into the pile 34 and ejecting it.

Furthermore, 36 is a water supply tank, and 37 is a water supply pump that supplies water under pressure to the steam generator via a water distribution pipe 38 from the water supply tank 36.

On the other hand, 39 is a drivable rotary brush 4 held at both ends.
0 and a drive motor interlocked by a belt 41.

Further, 42 is a piece movably attached to support the main body 25, and 43 is an operation frame attached to the main body 26.

Next, the operation of the configuration of this embodiment will be explained.

The water supplied by the water supply pump 37 to the first vaporization chamber 29 whose temperature is controlled to the optimum temperature for steam generation by the temperature controller is vaporized in the first vaporization chamber 29, passes through the hole 28, and flows into the second vaporization chamber 3o. It is squirted to This ejected steam is
The steam is further heated and expanded in the vaporization chamber 3o, and the steam ejection hole 33
It is ejected into the outside air. At this time, the steam ejected into the second vaporization chamber 3o collides with the floor surface of the nozzle part 36 and tries to spread laterally, but by providing the small chamber 31,
The horizontal spread of steam is appropriately prevented, and steam is also jetted out from the lower part of the hole 28 due to the increase in pressure within the small chamber. Furthermore, the amount of steam ejected can be adjusted by changing the area of the opening of the small chamber 31, and the amount of steam ejected from each steam outlet 3 can be adjusted.
The steam uniformly ejected from the carpet 3 is blown into the pile 34, kills the mites living in the carpet, and is scraped up by the rotating brush 40, so that the pile 34 becomes fluffy.

Effects of the Invention According to the present invention, the amount of steam ejected from each steam outlet can be made constant, and variations in mite killing performance and fluffing effect depending on the position of the steam outlet can be eliminated, and the generated steam can be used without wasting it. It has the great effect of being able to be used efficiently.
