Abstract

PURPOSE:To let harmful insects such as ticks arrested within a dust collecting chamber die out so as to get rid of them by means of heating as well as to simplify its actuation by actuating a heating device provided apart from the inner wall of the dust collecting chamber, heating the dust collecting chamber, and thereby concurrently convecting air between the inner wall of the dust collecting chamber and the heating device. CONSTITUTION:When a heating device 9 is energized, the temperature within No.1 case 11, that is, a dust collecting bag 7 is elevated. When the temperature within No.1 case reaches a specified one, a thermostat 10 is actuated so that the heating device 9 is automatically de-energized. At this time, the dust collecting bag 7 is sufficiently heated up so that ticks and harmful insects among dusts within the dust collecting bag 7 die out. In addition, the heating device 9 is intended to be separated from the inner bottom surface of No.1 case 11 by means of a plug socket section 13, when the heating device 9 is moved, air is convected between the heating device 9 and No.1 case 11, heating within No.1 case 11 can thereby be accelerated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vacuum cleaner, and more particularly to a vacuum cleaner that can kill pests such as mites captured in a deer collection room.

[Conventional technology]

Conventional vacuum cleaners suck in dust, collect it in a dust bag that also serves as a filtration filter, and exhaust the air from which the dust has been removed. And I try to change the various cleaning attachments depending on the area I want to clean, such as the corner of a carpeted room.

Therefore, when cleaning with such a vacuum cleaner.

Along with the dust in the room, the dust mites living in the two rooms will also be collected in the dust collection bag. The mites then multiplied inside the dust bag, and in some cases even crawled out of the bag. These mites are known to cause asthma and skin allergies, and are not good for health, so we must avoid leaving them unattended as much as possible.

By the way, various studies have been conducted on these mites, and various reports have been made regarding their ecology. According to it, mites live at 25 to 30 degrees Celsius.

It is known that a relative temperature of 60 to 80% is the optimum range, and it is known that if the temperature exceeds the optimum range, for example 50°C, it will die in a few seconds, and it is also known that it does not like extremely dry conditions. Are known.

Conventional vacuum cleaners have measures against dust mites by impregnating dust bags with anti-mite chemicals to kill them, or recently by blowing warm air into the dust collection chamber.

There are products on the market that heat dust to a temperature that exceeds the optimal temperature for direct mites and kill the mites in the dust.

[Problem to be solved by the invention]

However, the chemicals impregnated into dust bags gradually evaporate and lose their medicinal efficacy, so they cannot necessarily be said to be effective against ticks, and at the same time, their safety is questionable due to their evaporative nature. there were.

Also, for devices that send hot air into the dust collection chamber to heat the dust, special operations are required to send the warm air into the dust collection room after the normal cleaning work is completed.

In addition, while blowing hot air, the plug must be connected to an outlet in order to energize the heat-generating blower, which is extremely troublesome in use.

The present invention has been made to solve the above problems, and aims to provide a vacuum cleaner that kills pests such as mites caught in a dust collection chamber by heating, and that is easy to operate. .

[Means to solve the problem]

A vacuum cleaner according to the present invention includes a dust collection chamber having an air intake port;
The blower chamber communicates with the dust collection chamber and has an exhaust port, and a heat generating device is provided floating above the wall of the dust collection chamber.

[For production]

In this invention, the heat generating device provided apart from the wall of the dust collection chamber is operated to heat the inside of the dust collection chamber and to cause air to flow between the wall of the dust collection chamber and the heat generating device.

〔Example〕

The present invention will be explained below based on an embodiment shown in FIG.

FIG. 1 shows a vacuum cleaner while cleaning a room. In the figure, the vacuum cleaner has a vacuum cleaner main body Il+,
A hose (3) is connected to the main body il+ via a pipe 121, and a floor brush (6) is connected to the hose (3) via a hand pipe (4) and an intermediate pipe (5). .

The vacuum cleaner body +11 is constructed by connecting a first case αυ and a second case σ2, both of which are r1υ, 0
3 is a hole (IIA) formed in each partition wall, (12
A). The intake port of the first case αυ (
11B) is equipped with a dust collection bag (7), and the first case a
It is located in the dust collection chamber (IIG) inside the υ.

The blower motor (
By the operation 8), air is sucked in the direction of the arrow. As a result, dust and pests such as mites are collected in the dust collection bag (7) via the floor brush (6). Since the dust collection bag (7) has the function of an air filter, the filtered air is passed through the holes (IIA) of each partition wall,
(12A) and reaches the second case [13], and the partition wall (12B) formed on the other end surface (12B) of the second case α2
It is exhausted to the outside via the hole (120) and the exhaust port (12ε) in C). The inside of this second case α2 is the blower chamber (
12F). Inside the first case 1111, a heat generating device (9) and a thermostat αQ that detects a predetermined air temperature and stops power supply to the heat generating device (9) are provided. (IOA) also serves as a switch that starts energizing the heat generating device (9) with the reset button of thermostat G [. (8A) turns on and off the blower motor (8) with a remote switch provided on the hand pipe (4).
(8B) Hub a 17-T--ta (8777) Anti-vibration rubber, W, W2 is case 0. The wheel (L3) is an outlet member provided on the inner bottom wall of the first case αυ, and detachably supports the plug part (9A) provided on the f side of the heat generating bag fi +91. do.

In the above configuration, the remote switch (8A
) is turned OFF and the heat generating device (9) is energized by operating the reset button (IOA).
That is, the temperature of the dust bag (7) increases. When the temperature inside the first case reaches a predetermined value, thermostat αG is activated.
The power supply to the heat generating device (9) is automatically stopped. At this point, the dust bag (7) is sufficiently heated.

Mites and pests in the dust inside the dust collection bag (7) are killed. Here, the thermostat αG not only simply turns off the power to the heat generating device (9), but also actively controls the power and time control of the heat generating device (91) to maintain the temperature inside the first case at a predetermined temperature. It is also possible to hide it in the controller that performs it.

Further, a timer may be set to energize the heat generating device for a necessary predetermined time.

Furthermore, the heat generating device may be energized only while the IE vacuum cleaner is in operation. In addition, the heat generating device (9) is located at the outlet part a.
3, the first case dυ is separated from the inner bottom surface, and when the first heat generating device (9) moves, air convection occurs between the first heat generating device (9) and the first case συ, and the first case αυ This can promote internal heating. Further, since the heat generating device (9) is detachable, it can be removed when not needed, and the dust collection chamber (IIC) can be made larger.

Figure 2 shows another embodiment of the present invention, with two heat generating devices (
9) has a heat storage material (9b) that stores heat once. a
Reference numeral 4 denotes a temperature controller wJ for preventing an abnormal temperature rise of the heat storage material (9b), which performs control operations such as stopping power supply to the heat generating device (9) when the heat storage material (9b) exceeds a predetermined temperature. Let's do it. The heating device (9) is energized when the remote switch (8A) is turned on, that is, during cleaning.

Power is not applied when the remote switch (8A) is OFF. Therefore, heat is stored in the heat storage material (9b) during cleaning, so even if you unplug the power plug (not shown) immediately after cleaning and clean it up, the dust collection bag (7) will not work due to the heat dissipated from the heat storage material (9b). It is heated and can kill mites and pests in the dust. In other words, the user of the vacuum cleaner will be able to exterminate all the mites (this action will be performed automatically every time without being conscious of it).

FIG. 3 is a structural diagram of the heat generating device.

The outer shell (9G) of the heat generating device is made of heat resistant material,
A heating element such as a nichrome wire heater or a semiconductor heater is provided inside. In addition, heat storage material as shown in Figure 2 (
