Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a dust collector, a so-called central cleaner, in which a main body and a hose outlet are connected by piping.

Conventional technology Conventionally, instead of floor-moving vacuum cleaners, so-called central vacuum cleaners installed electric blowers and dust collectors in one area of the house, and connected them with hose outlets and piping installed on the floor and walls. Many cleaners have been devised and implemented.

For the purpose of eliminating dust clogging in the piping of this central cleaner or making it possible to use thin piping, a system as shown in Figure 2 has been devised (Utility Model Publication No. 55-39041). .

That is, a main body 1 equipped with a built-in electric blower provided in one area of the house and a hose insertion port 2 provided on the floor of the house are connected through piping 3 in an airtight manner. A long hose 4 is inserted into the hose insertion port 2, and a dust collection case 5 with a built-in filter (not shown), an extension pipe 6, and a suction port body 7 are connected to its tip. 8 is a remote control switch, and 9 is a cover for the hose insertion port.

Problems to be solved by the invention Normally, in these conventional dust collectors, the degree of filter clogging is shown in the dust collection case.
Equipped with an indicator that shows when it is time to throw away the garbage,
At the same time, it is common to add an air protector function that introduces cooling air from an electric blower when the filter becomes clogged. However, in central cleaners, the air protector that doubles as an indicator installed in the dust collection case is useful when the filter is clogged, but it is of no use when the pipes become clogged with dust, and can cause damage to the electric blower such as burnout. There are things that can lead to this. In addition, in this conventional system, there is no means to drain water from the casing of the main body, for example, when an infant or the like pours water from the outlet, and it is necessary to disassemble the main body each time.

Therefore, the present invention aims to provide a main body of a central cleaner that can prevent the electric blower from burning out when the piping is clogged with debris, and can easily drain water when water enters the pipe.

Means to Solve the Problems The technical means of the present invention to solve the above problems is to provide a small hole that is opened and closed by a valve on the bottom surface of the casing of the main body, and a corresponding small hole in the bottom plate. It is something.

Function The technical means of this invention allows air to cool the electric blower to flow even when the piping becomes clogged with debris, and even when water accumulates inside the casing, water can be drained without disassembling the main unit. It is possible.

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

In FIG. 1, a bottom plate 11 is provided on the bottom surface of the main body 10.
is attached, and a substantially trapezoidal casing 12 is attached above the bottom plate 11. A fan case 16 of an electric blower 15 is vertically installed above the casing 12 with packings 13 and 14 interposed therebetween, and is held between a holding plate 17 and a fan case 16 . A pipe 18 is integrally formed on the side surface of the casing 12 in a horizontal direction. Further, a flat mounting portion is integrally formed on another side of the casing 12, and a magnetic relay 19 for remote control is mounted thereon. 20 is soundproofing material such as felt, 21
2 is a leg rubber, and 22 is an intake connection pipe. This intake connecting pipe 22 is connected to the horizontal pipe 18 of the casing 12, the main body 10, and the tight packing 23.
The other end is connected via a hose or the like to piping leading to the hose insertion port. 24 is an exhaust port.

A small hole 25 is formed in the lower surface of the casing 12. This small hole 25 is normally closed by a valve 27 biased by a spring 26. 28 is a spring holder. On the other hand, the bottom plate 11 is also provided with a small hole 29 corresponding to the small hole 25 of the casing 12.

It should be noted that the configuration other than the main body 10 is the same as the conventional configuration shown in FIG. 2, so the explanation is omitted.

As is clear from the above configuration, not only when the filter in the dust collection case becomes clogged and the air volume decreases, but also when the piping is clogged with dust or foreign matter.
The negative pressure inside the casing 12 increases, the valve 27 rises against the spring 26, and air for cooling the electric blower 17 flows in through the small hole 25, which can prevent problems such as burnout. It is something.

In addition, if water enters the casing 12 from the insertion port and accumulates, the water can be easily drained without disassembling the main body 10 by pushing up the valve 27 with a rod or the like through the small hole 29 of the bottom plate 11. Yes, electric blower 17
The insulation will not deteriorate.

Effects of the invention As is clear from the configuration described above, the dust collector of the present invention has an air protector installed at the bottom of the casing of the main unit, so it can be used not only in the case of filter clogging, but also in the case of dust clogging in the piping. The electric blower can be protected, and the water inside the casing can be easily removed without disassembling the main body.
