Abstract

PURPOSE:To permit a thermoswitch to function surely and improve using convenience by arranging the thermoswitch and its operating button on a hose to be used for tick-killing work, near the tip of the hose. CONSTITUTION:The positions of a thermoswitch and its operating button 6 are arranged on a hose to be used for tick-killing work near the tip 2a of the hose As a result, various switch buttons on the hose are arranged in the order of a clamping button 3, the operating button 6 of the thermoswitch, the operating button 4 of a power brush switch, and the operating button 5 of a main body controlling switch, from the tip section of the hose. Accordingly, the temperature sensor of the thermoswitch is also set near a vacuum cleaner main-body, and the temperature of a main body necessary-section is also detected with less error. Besides, the position of the operating button 6 of the thermoswitch is set on the side of the main body to be closer to the side than the operating button 5 of the controlling switch of the main body, and so when the operating button 5 of the controlling switch is operated, trouble due to erroneously contacting the operating button 6 of the thermoswitch, stopping the motor of the main body 1, and the like are avoided.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vacuum cleaner with a dust mite killing function.

[Prior Art] Among the various vacuum cleaners that have been commercially available, the vacuum cleaner sold under the trade name of Dani Punch, which has the function of killing dust mites, has the ability to kill dust mites, which are a nuisance in the home. It is generally well-received because it can be easily exterminated.

The mechanism that uses this vacuum cleaner to kill dust mites is to first clean the place where dust mites live with the vacuum cleaner, then suck up the dust mites along with the dirt and collect them in a paper pack built into the vacuum cleaner itself. do. Next, connect the end of the hose on the exhaust side of the vacuum cleaner to the intake side, drive the fan of the vacuum cleaner to return the exhaust to the intake side, and circulate the air between the vacuum cleaner and the hose. As the temperature of the circulating air rises, the temperature inside the vacuum cleaner hose and paper pack rises to over 50°C, and this heat kills the dust mites that are mixed in with the dust inside the hose and paper pack. It is generally said that mites are sensitive to heat and dryness, and it is said that more than 99% of mites will die if the temperature exceeds 50°C, so the above method can easily get rid of mites in the home.

Figure 3 is a perspective view of the vacuum cleaner while killing the mites, Figure 4
The figure is a perspective view of the hose, in which (1) is the main body of the vacuum cleaner, (2) is the hose, (2a) is its tip, (3)
is the operation button for the clamping device, (4) is the operation button for the power brush switch, (5) is the operation button for the main power control switch, (6) is the operation button for the thermo switch, and (7) is the air circulation direction. This is an arrow indicating.

As shown in the figure, connect the tip (2a) of the hose (2> to the suction side (1a) of the vacuum cleaner body (1), and
1) Drive the fan inside to circulate air between the vacuum cleaner body (1) and the hose (2). As a result, the temperature of the circulating air rises to over 50℃ due to the exhaust heat from the motor inside the vacuum cleaner body (1), and this heat kills the dust mites inside the paper pack and hose (2) of the vacuum cleaner body (1). .

[Problem to be Solved by the Invention] The hose (2) of the conventional vacuum cleaner described above has a clamping device for engaging the distal end (2a) of the hose to the intake port (1a) of the main body in order from the distal end. operation button (3), operation button (4) for the power bran switch to operate the power brush, operation button (5) for the main power control switch for operating the vacuum cleaner's fan and other operations.
), and a thermoswitch operation button (6) for turning off the main body fan when the temperature of the main body part exceeds a predetermined temperature are arranged in a - row.

By the way, among the above switches, the thermo switch operation button (6) is installed at the hose tip (2a).
), the temperature sensor of the thermo switch is further away from the vacuum cleaner body (1) when punching ticks, so the vacuum cleaner body (1)
The error in temperature detection becomes large.

In addition, the operation button (5) of the main power control switch
) is located closer to the main body than the thermo switch operation button (6), so when operating the control switch operation button (5), your hand may accidentally touch the thermo switch operation button (6), causing the main body The fan motor may stop.

As described above, in conventional vacuum cleaners, there is a lack of consideration in the arrangement of the operation buttons for the various switches on the hose, resulting in problems such as a decrease in the accuracy of the thermoswitch and poor usability.

The present invention has been made to solve the above-mentioned problems of conventional vacuum cleaners, and aims to provide a vacuum cleaner in which a thermoswitch functions reliably and is easy to use.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a hose used for the mite extermination process of a vacuum cleaner, in which the thermo switch and its operation button (6) are located near the tip of the hose. .

[Function] Since the thermoswitch is located near the tip of the hose, when using the vacuum cleaner to kill mites, the thermoswitch's temperature sensor is also located near the main body of the vacuum cleaner, which measures the temperature of the main body parts. Can be detected accurately. This improves the accuracy of the thermoswitch, making it possible to completely kill mites.

In addition, the thermo switch's operating button is located closer to the hose tip than the power control switch's operating button, so when operating the power control switch's operating button, your hand does not touch the thermo switch's operating button. Thermo switch malfunctions are eliminated.

[Embodiments of the Invention] Fig. 1 is a perspective view of a hose used in a vacuum cleaner to kill dust mites, and Fig. 2 is a perspective view of a vacuum cleaner used to kill dust mites. indicates the same or equivalent parts.

As shown in the figure, the thermoswitch and its operation button (6) placed on the hose used for the mite extermination work were located near the hose tip (2a).

As a result, the arrangement of the various switch buttons on the hose is as follows:
The order from the hose tip is the clamping button (3), the thermo switch operation button (6), the power brush switch operation button (4), and the main body control switch operation button (5).

For this reason, the temperature sensor of the thermoswitch is also closer to the vacuum cleaner body, and the error in detecting the temperature of the main body part is reduced. In addition, the thermo switch operation button (6) is located closer to the main body than the control switch operation button (5) on the main body, so the control switch operation button (5)
), there will be no more troubles such as accidentally touching the operation button (6) of the thermoswitch with your hand and stopping the motor of the main body (1).

[Effects of the Invention] In the vacuum cleaner according to the present invention, the thermoswitch and its operation button (6) placed on the hose used for mite killing work are located near the tip of the hose, so that the vacuum cleaner according to the present invention has the following advantages: This resulted in excellent results.

(1) The temperature sensor of the thermoswitch is placed near the main part of the vacuum cleaner, so it can accurately detect the temperature of the main part of the vacuum cleaner, allowing it to stop the motor before the dust mites are sufficiently killed. There is no longer any problem caused by overheating due to delayed motor stop timing.

(2) The thermo switch operation button is located closer to the main body than the main body control switch operation button.
When operating the operation button of the main body control switch, it is no longer possible to accidentally touch the operation button (6) of the thermoswitch with your hand and cause a malfunction.
