DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric vacuum cleaner, and more particularly, to an electric vacuum cleaner which displays an environmental state in which mite breeding is activated and a state of sucked dust. It is.

[0002]

2. Description of the Related Art In recent years, health diseases caused by mites have been called out, and in particular, social problems have developed with the increase in atopic patients. In such a situation, the ticks sucked by the vacuum cleaner are exterminated with hot air, or, for example, as described in Japanese Patent Publication No. 2-264622, the indoor environmental condition in which the reproduction of ticks is activated, that is, When the temperature becomes 20 to 30 ° C. and the humidity becomes 60 to 80%, the mite information is displayed to alert the user to perform careful cleaning.

Further, in order to inform the user of the cleaning condition of the floor surface and to perform efficient cleaning, for example, Japanese Patent Publication No. 5-48688 discloses a suction device for a floor suction device of a vacuum cleaner. A dust sensor is provided in the air passage, and if dust is contained in the suction air, the dust sensor detects this and displays it with a display lamp, etc., so that the user can clean the display lamp etc. until it goes off. Announcing the continuation of Thereby, the cleaning efficiency of the floor surface is improved.

[0004] Further, even in the case of a floor suction tool or the like which is an accessory that is used away from the cleaner body, the power from the cleaner body is not required and the electric parts can be driven independently. As disclosed in JP-A-98846, a dust sensor as an electrical component is driven by mounting a generator on a floor suction tool or the like to detect the presence or absence of passing dust. This allows
Wiring for power supply from the main body of the vacuum cleaner is not required, and the poor connection and the assembling work associated with the electrical connection are improved.

In the above-mentioned conventional vacuum cleaner, the invention described in Japanese Patent Application Laid-Open No. 2-264622 only displays the indoor environmental condition. It was unclear whether cleaning should be done carefully. In addition, the invention described in Japanese Patent Publication No. 5-48688 only displays the presence or absence of dust sucked from the floor surface, and does not take into account the display associated with the indoor environmental condition or the adjustment of the suction force. For example, dust when it is dry is relatively light, so it is easy to suck it.On the contrary, when the humidity is high, dust is relatively heavy and it is difficult to suck it, and it is easy to breed under special environmental conditions. It is difficult to understand any measures against suction of microorganisms such as mites and molds.
The response was unclear.

Further, in the invention described in Japanese Patent Application Laid-Open No. 6-98846, a dust sensor is driven by supplying power from a generator mounted on a floor suction tool.
The display of the indoor environmental condition is not taken into account, and the generator is not actively used.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and includes information on tick information based on environmental conditions in a room where mite breeding is activated and information on dust in an air flow passing through a suction air passage. It is an object of the present invention to obtain an electric vacuum cleaner capable of efficiently sucking and collecting microorganisms such as dust and ticks on the main body of the cleaner by detecting both or any one of them. Further, the present invention provides an electric power supply to a printed circuit board, a dust sensor, a tick detector, and a display, which is performed by a generator that generates electricity by suction airflow without using a power supply wiring from a cleaner body. It is intended to obtain a vacuum cleaner.

In the above-described power generator 41, when the electric blower 2 is driven and the pressure in the suction air passage 21 becomes negative, outside air is sucked from the air holes 18a to 18c and flows into the case 11. The outside air passes around the tick detector 47 and the temperature and humidity in the room are detected, flows into the cover 44 from the ventilation holes 46a and 46b, rotates the turbine 43, and is sucked from the hollow bearing 24a into the suction air passage 21.

Next, the operation of the present embodiment configured as described above will be described. 7, when the electric blower 2 of the cleaner body 1 is driven, air including dust and the like is sucked from the floor suction tool 10 and the power brush 15 is
, The turbine 43 of the power generator 41 is driven by the airflow sucked from the air holes 18a to 18c, and the generator 42 outputs AC power by the rotation of the rotor. This AC output is converted to DC by the DC power supply circuit 64 and supplied to the printed circuit board 48, the tick detector 47, the dust sensor 30, the display unit 51, and the like.

On the other hand, the temperature and humidity of the room air flowing from the air holes 18a to 18c and detected by the tick detector 47 are compared with a set temperature (for example, 20 ° C.) by the temperature comparing circuit 66, and the humidity is compared. The humidity set at the circuit 67 (for example, 6

Alternatively, the amount of dust or the like per unit time is detected, and the detection signal is applied to the dust detection circuit 69.

First, if the room temperature and humidity detected by the tick detector 47 are both lower than the set temperature and the set humidity, there is no tick information, and no signal is output from the temperature / humidity comparison circuit 65. On the other hand, the dust detection circuit 69, which has received the detection signal from the dust sensor 30,
Is sent to the display driving means 71, and the display driving means 71 drives (lights) the dust display 53 based on this signal. At this time, the tick indicator 52 is not lit, indicating that it is not a mite breeding environment. When the detection signal of the dust sensor 30 becomes zero, the result is sent to the display driving means 71, and the dust display 53 is turned off, thereby completing the cleaning.

Next, when both or one of the room temperature and the room humidity is higher than the set value, the temperature and humidity comparison circuit 65
Sends a signal to the dust sensor sensitivity setting means 68 to change the sensitivity of the dust sensor 30 to a corresponding sensitivity (for example, the case where dust or the like up to 1 μm has been detected is changed to
Detect dust and the like up to 0.5 μm). Then, the dust detection circuit 69 sends a signal indicating that the sensitivity has been changed to the display time setting means 70, and changes the lighting time so that the dust indicator 53 can be turned on for a time corresponding to the sensitivity change. In other words, the lighting time is extended so that cleaning can be performed carefully over time. The output signal of the display time setting means 70 is sent to the display driving means 71 and the tick display 52
Is turned on, and the dust indicator 53 is turned on for the changed time. When a predetermined time has elapsed, the tick indicator 52 and the dust indicator 53 are turned off.

As described above, in the present embodiment, when the electric blower 2 of the cleaner main body 1 is driven to start suction in the season (environmental condition) in which ticks do not breed, the dust indicator 53 is turned on, and the suction is performed. The light turns off when no dust or the like disappears in the airflow, and thus the floor surface and the like can be cleanly cleaned by performing cleaning while the dust indicator 53 is on. In this case, since the tick detector 47 is provided at a position closest to the floor F, the tick information can be accurately detected.

In an environment in which ticks proliferate, the tick detector 47 detects the temperature and / or humidity in the room by the operation of the blower motor 2, and if this exceeds a set value, the sensitivity of the dust sensor 30 changes. And the dust indicator 5
The lighting time of 3 is extended, and both the tick indicator 52 and the dust indicator 53 light. Thereby, the dust indicator 53
While the light is on, careful cleaning can suck fine dust and the like, and can reliably collect mites.

When the tick information is obtained in a mite breeding environment, only the sensitivity adjustment of the dust sensor 30 may be performed, and the tick indicator 52 and the dust indicator 53 may be turned on (FIG. 7 (dashed line 61), or the tick indicator 52 and the dust indicator 53 may be turned on without adjusting the sensitivity of the dust sensor 30 and changing the lighting time of the dust indicator 53 (dashed line in FIG. 7). 62).

The ticks collected in the dust collecting bag 3 as described above are connected, for example, by connecting the gripping portion 6 side of the suction hose 4 to the exhaust port of the cleaner body 1 and circulating the heated air. When the electric blower 2 is driven by forming the air blower, mite mixed in dust or the like in the dust bag 3 can be killed.

Embodiment 2 In the present embodiment, the tick indicator 52 and the dust indicator 53 according to the first embodiment are described.
, The display unit 51 is provided with two or three or more indicators fed from the generator 42, and one of these indicators is provided.
(Hereinafter referred to as a display A) is controlled by a signal (mite information) from the tick detector 47, and another display (hereinafter referred to as a display B) displays dust information from the dust sensor 30, for example. Alternatively, the dust information is displayed by switching according to the cleaning density. That is, when there is no signal (mite information) from the tick detector 47, and therefore from the temperature / humidity comparison circuit 65, only the display B is turned on by the signal (dust information) from the dust sensor 30, and when there is tick information. Indicates that the display A and the display B are turned on. In this case, when there is tick information, the sensitivity of the dust sensor 30 may be changed by the signal from the temperature and humidity comparison circuit 65, and the display time of the display B may be changed.

According to the present embodiment, it is possible to easily know whether or not the mite is in a breeding environment, and it is sufficient to perform cleaning while the indicator B is on. Can collect ticks.

Embodiment 3 In the present embodiment, only one dust indicator 53 is provided on the display unit 51 in the first embodiment, and the dust indicator 53 is controlled by an output signal of the tick detector 47 (temperature and humidity comparison circuit 65). It was made. That is, the dust indicator 53 is provided by the tick detector 47.
When there is no tick information from the camera, dust information is displayed by a signal from the dust sensor 30. Based on this, cleaning is performed while the dust indicator 53 is lit.

When tick information is received from the tick detector 47, the sensitivity of the dust sensor 30 is changed and the display time of the dust display 53 is changed by the output signal of the temperature / humidity comparing circuit 65. To light the dust indicator 53. Thereby, the mites can be reliably collected. According to the present embodiment, the structure of the display unit 51 can be simplified.

Embodiment 4 FIG. FIG. 8 is an explanatory diagram of a main part of a fourth embodiment according to the present invention. In the present embodiment, a tick indicator 52a for displaying the environmental state of the room where mite breeding is activated, a tick removal indicator 52b for indicating that the tick has been removed, and a passage through the suction air passage 21 The display unit 51 includes a dust indicator 53a for displaying the presence of dust to be removed and a dust removal indicator 53b for indicating that dust passing through the suction air passage 21 has disappeared. Each of these indicators 52a, 52b,
For 53a and 53b, other means such as using lamps of different colors may be used instead of the example of FIG.

Next, the operation of the present embodiment having the above-described display section 51 will be described with reference to FIG. When the indoor temperature and humidity detected by the tick detector 47 are both lower than the set temperature and the set humidity, there is no tick information, and no signal is output from the temperature / humidity comparison circuit 65. On the other hand, the dust detection circuit 69 receiving the detection signal from the dust sensor 30
Its output signal is indicated by a broken line 61 as indicated by the display driver 7.

3b does not ignite. Neither the tick indicator 52a nor the tick extermination indicator 52b is lit, indicating that it is not a mite breeding environment. When the detection signal of the dust sensor 30 becomes zero, the result is sent to the display driving means 71, the dust display 53a is turned off, and the dust removal display 53b is turned on, thereby completing the cleaning.

Next, when both or one of the room temperature and the room humidity is higher than the set value, the temperature and humidity comparison circuit 65
Sends a signal to the dust sensor sensitivity setting means 68 to change the sensitivity of the dust detection circuit 69 to the sensitivity corresponding thereto. Then, the dust detection circuit 69 sends a signal indicating that the sensitivity has been changed to the display time setting means 70, and changes the lighting time so that the dust indicator 53a can be turned on for a time corresponding to the sensitivity change. In other words, the lighting time of the dust indicator 53a is extended so that the dust can be carefully cleaned over time. The output signal of the display time setting means 70 is sent to the display driving means 71 to light the tick display 52a and to light the dust display 53a for the changed time. When a predetermined time has elapsed, the tick indicator 52a and the dust indicator 53a are turned off, and the tick removal indicator 52b and the dust removal indicator 53b are turned off.
Is turned on, and the cleaning is finished after seeing this.

As described above, in the present embodiment, in the season in which ticks do not breed (environmental conditions), when the electric blower 2 of the cleaner main body 1 is driven to start suction, the dust indicator 53a is turned on, and the suction is performed. When the dust or the like disappears in the air flow, the light goes off and the dust removal indicator 53b is turned on. Therefore, if cleaning is performed during this time, the floor surface and the like can be cleaned and dust mites can be collected.

Further, in an environment where ticks are propagated, the tick detector 47 detects the temperature and / or humidity in the room by the operation of the blower motor 2, and when this exceeds a set value, the sensitivity of the dust sensor 30 is changed. And the dust indicator 5
The lighting time of 3a is extended, and both the tick indicator 52a and the dust indicator 53a are turned on. As a result, until the dust indicator 53a and the tick indicator 52a are turned off and the dust removal indicator 53b and the tick removal indicator 52b are turned on, fine dust and the like are suctioned by performing careful cleaning, Mites can be reliably collected.

In the mite breeding environment, when the tick information is obtained, only the sensitivity of the dust sensor 30 is adjusted, and the tick indicator 52a and the dust indicator 53a are turned on. These may be turned off so that the mite extermination display 52b and the dust removal display 53b are turned on (broken line 61 in FIG. 9), or the sensitivity of the dust sensor 30 is adjusted and the lighting time of the dust display 53a is changed. , The tick indicator 52a and the dust indicator 53a may be turned on, and when dust is gone, they may be turned off and the tick removal indicator 52b and the dust removal indicator 53b may be turned on (FIG. 9). Broken line 62).

Embodiment 5 FIG. In the present embodiment, when the tick information is obtained, in addition to any of the various operations described above, the output signal of the temperature / humidity comparing circuit 65 is output as indicated by a broken line 63 in FIG. 7 or FIG.
