Description

  The present invention relates to a cyclone type electric vacuum cleaner.

  2. Description of the Related Art In recent years, a so-called cyclonic vacuum cleaner, which has a swirling component in sucked air and separates and removes dust from an air stream by centrifugal force, has attracted attention. In this type of vacuum cleaner, as shown in FIG. 11, an intake passage 1 for allowing air containing dust to flow from the outside into the interior, and an electric blower (not shown) for generating intake air in the intake passage 1, A dust collecting chamber 2 that separates the air containing dust that has passed through the intake passage 1 into dust and air by swirling and accumulates at the bottom, and an atomizing device 3, and the atomizing device 3 has ultrasonic vibration means 4. It comprises an atomizing cylinder 5 and a water supply cylinder 6 for supplying water to the atomizing cylinder 5. Then, water supplied from the water supply cylinder 6 is atomized by the ultrasonic vibration means 4 and water particles having an average particle diameter of 50 μm or less are supplied to the upstream side of the dust collection chamber 2 (for example, Patent Documents). 1).

  However, since a separate power source is required, the usability is poor, and as shown in FIG. 10, a configuration using thermal energy during operation of the electric blower is also conceivable. It is a configuration having a moisture absorbing / releasing member 7 for supplying humidity to the dust and a humidity control container 8 for accommodating it in order to improve dust collection efficiency. For example, when a moisture absorbing / releasing member 7 such as silica gel is used, heating is required to release moisture. At this time, in order to give heat to the moisture absorbing / releasing member 7, heat can be received by directly fixing the humidity control container 8 to the electric blower 9.

Japanese Patent Laid-Open No. 9-253011

  However, in order to use the heat of the electric blower 9, if the humidity control container 8 is directly adhered and fixed to the electric blower 9, the generation of noise or the inside of the humidity control container 8 is caused by vibration accompanying the rotation of the electric blower 9. There is a problem that the moisture absorbing / releasing member 7 is exposed to vibration and reliability is deteriorated (cracked, dropped off, etc.).

  The present invention solves the above-mentioned conventional problems, heats the humidity control container that houses the moisture absorbing / releasing member using the heat of the exhaust air of the electric blower, and further vibrates with the rotational operation of the electric blower. The purpose is to provide a highly reliable electric vacuum cleaner that does not transmit to the humidity control container and dust collection case, so that the vibration of the electric blower is not transmitted to the humidity control container, and noise and moisture absorption / release members do not fall off. To do.

In order to achieve the above object, the vacuum cleaner of the present invention comprises:
An electric blower that generates a suction force;
A suction port provided in the vacuum cleaner body for sucking air containing dust;
A dust-collecting case main body that is detachably disposed on the vacuum cleaner main body and has a discharge port that communicates with the electric blower at the top;
A dust separation unit arranged in the dust collection case body for separating the dust containing air sucked by the electric blower;
A dust collection chamber that is disposed in the dust collection case body, is located below the dust separation unit, and stores the separated dust;

By facing the humidity control container in the electric blower case and placing the second container in contact with the electric blower,
The elastic member suppresses the vibration of the electric blower from being transmitted to the moisture absorbing / releasing member and the dust collecting case main body.

  Receiving heat from the exhaust air from the electric blower to the humidity control container and suppressing the vibration caused by the rotation of the electric blower, the moisture absorption / release member and the dust collection case body are not exposed to the vibration of the electric blower High vacuum cleaner can be provided.

The first invention is
An electric blower that generates a suction force;
A suction port provided in the vacuum cleaner body for sucking air containing dust;
A dust-collecting case main body that is detachably disposed on the vacuum cleaner main body and has a discharge port that communicates with the electric blower at the top;
A dust separation unit arranged in the dust collection case body for separating the dust containing air sucked by the electric blower;
A dust collection chamber that is disposed in the dust collection case body, is located below the dust separation unit, and stores the separated dust;
An air inlet that is provided in the outer circumferential direction of the dust separation unit and sucks air containing dust; and
An opening opening in the dust collection chamber;
A humidity control container integrally configured via an elastic member between a first container supporting the moisture absorption / release member inside and a second container transmitting heat from the electric blower to the inside;
An electric blower case that covers the entire outer periphery of the electric blower with a gap and discharges the exhaust to the outside,
The humidity control container faces the electric blower case, and the second container is disposed in contact with the electric blower.

Thereby, the humidity control container can receive the heat from the electric blower from the second container by heat conduction, and can transmit this heat to the moisture absorbing / releasing member supported inside the first container.
In addition, since the humidity control container is integrally configured between the first container and the second container via an elastic member, the rotation of the electric blower received by the second container that is in close contact with the electric blower The vibration associated with is not transmitted to the first container. Therefore, vibrations are not transmitted to the moisture absorbing / releasing member held in the first container, the dust collecting case main body connected to the humidity control container, or the like.

  Therefore, the heat receiving from the electric blower to the humidity control container and the suppression of the vibration caused by the rotation of the electric blower are both compatible, and the moisture absorbing / releasing member and the dust collection case main body are not exposed to the vibration of the electric blower. A vacuum cleaner can be provided.

  In a second aspect of the invention, in particular, in the first aspect of the invention, the elastic member is a vibration-proof rubber. Thereby, the vibration accompanying the rotation of the electric blower received by the second container in close contact with the electric blower is not transmitted to the first container due to the damping action of the vibration isolating rubber. Therefore, vibration is not transmitted to the moisture absorbing / releasing member held in the first container, the dust separating part connected to the humidity control container, or the like.

  Therefore, it is possible to provide a highly reliable electric vacuum cleaner that suppresses vibrations associated with the rotation of the electric blower and does not expose the moisture absorbing / releasing member and the dust separator to the vibration of the electric blower.

FIG. 7 is a perspective view of the elastic member of the electric vacuum cleaner, and FIG. 8 is a relationship diagram between the relative humidity and the moisture absorption rate of the moisture absorbing / releasing member at the time of equilibrium of the electric vacuum cleaner.

  As shown in FIG. 1, wheels 22 and casters 23 are attached to the outside of the cleaner body 21, and the cleaner body 21 can freely move on the floor surface. An extension pipe 28 having a suction hose 26 and a handle 27 is sequentially connected to the suction port 25 provided below the dust collection case 24 installation portion, and a suction tool 29 is attached to the tip of the extension pipe 28. Yes.

  As shown in FIGS. 1 and 2, the dust collecting case 24 is detachably attached to the cleaner body 21 containing the electric blower 30 and is inclined at an angle of about 45 ° with respect to the horizontal. 21, the suction port 31 on the inlet side of the dust collection case 24 communicates with a suction path 32 that opens the suction port 25, and the discharge port 33 on the outlet side of the dust collection case 24 communicates with the electric blower 30. .

  As shown in FIGS. 3 and 4, the dust collection case 24 is a cylindrical primary swirl chamber 34 (dust separation unit) that takes in air containing dust and generates a swirling airflow, and a substantially cylindrical 2 located below the cylindrical swirl chamber 34. A rectangular parallelepiped dust collecting chamber 35 that is configured by the next swirl chamber 39 (dust separating portion) and stores dust is positioned below the swirl chamber 39 (dust separating portion).

  The primary swirl chamber 34 is provided with an intake port 31 opened so as to be tangential to the inner peripheral surface of the cylindrical outer shape, and a cylindrical exhaust tube 36 communicating with the discharge port 33 at the center. Yes. A ventilation portion 37 is formed by a filtration filter such as a mesh filter or an etching filter on the outer peripheral side wall of the exhaust pipe 36 to prevent coarse dust from passing through the exhaust pipe 36. In addition, a non-woven fabric filter folded in a pleat shape is disposed as the second dust separating means 38 between the exhaust tube 36 and the discharge port 33. The dust collection chamber 35 is disposed below the primary swirl chamber 34 at positions where the respective central axes are shifted in parallel to the horizontal direction so as to communicate with the secondary swirl chamber.

  An opening 41 is opened on the ceiling surface of the dust collection chamber 35. The opening 41 is located at a position where it overlaps with the compression plate 43. When the compression plate 43 is biased by a spring and located at the upper portion, the opening 41 is closed, and the air between the humidity control container 44 and the dust collection chamber is closed. I try not to go in and out.

  As shown in FIGS. 3 and 4, the dust inflow port 40 to the dust collecting chamber 35 is formed on the upstream side of the swirling airflow of the wall 39 a that separates the secondary swirling chamber 39 and the dust collecting chamber 35. A part of the arcuate wall portion of the secondary swirl chamber 39 is extended in the tangential direction of the arc of the secondary swirl chamber 39 to form an introduction side wall portion 39b, and the opening range of the inflow port 40 is extended to the introduction side wall portion. The inflow path is configured by expanding.

  As shown in FIG. 5, the compression means 42 is provided with a flat compression plate 43 that moves up and down in the dust collecting chamber 35, is manually lowered, and is raised by a spring (not shown). The compression plate 43 sets a gap (for example, 1 to 3 mm) between the compression plate 43 and the dust collection chamber 35 that does not rub against the dust collection chamber 35 and on which the dust accumulated during compression does not escape.

  In addition, the electric blower 30 is attached to the outer peripheral support member 51 and the bottom support member 52 through a member having elasticity such as rubber or sponge between the electric blower body 21 and the cleaner body 21.

  The humidity control container 44 has a humidity control port 44a at the end close to the dust collection chamber 35. The opening 41 of the dust collection chamber 35 and the humidity control port 44a of the humidity control container 44 have a circle with an elbow. They are connected by a single communication pipe 48 in cross section.

  As shown in FIG. 6, the humidity control container 44 is divided into a first container 44 b and a second container 44 c, and the first container 44 b and the second container 44 c are, for example, in a cylindrical shape. It functions as a humidity control container 44 that is connected integrally with an elastic member 46 such as a vibration rubber and has a single cavity inside.

  The humidity control port 44a is provided on the first container 44b side, and holds the moisture absorbing / releasing member 45 therein. On the other hand, at least one surface of the second container 44 c is in close contact with the electric blower 30. In this way, heat during operation of the electric blower 30 is transmitted to the air inside the humidity control container 44 to raise the temperature.

  The electric blower 30 and the second container 44c may be in close contact with each other via a heat conductor such as thermal grease.

  In addition, the inner diameter A of the fitting portion of the elastic member 46 in FIG. 7 is made tight with respect to the outer dimension of the first container 44b, and the first container 44b is press-fitted into the elastic member 46 and adjusted. The air inside the wet container 44 is held without leaking outside. And the 2nd container 44c is attached similarly to the 1st container 44b. However, the attachment method is not limited to this, and adhesion or fixing with screws may be used.

  Further, as the moisture absorbing / releasing member 45, for example, 10 g of Tuftic HU (higher moisture absorption than silica gel) manufactured by Nippon Extra Industry Co., Ltd. was attached to a corrugated honeycomb (for example, pitch 1 to 3 mm, height 1 to 3 mm). The moisture absorbing / releasing member 45 is installed at substantially the center in the height direction in the humidity control container 44, so that the humidity control container 44 is electrically connected to the first container 44b that is the dust collection chamber side space. It is divided into a second container 44c which is a blower side space. The corrugated honeycomb is installed so that the ventilation direction connects the dust collection chamber side space of the first container 44b and the electric blower side space of the second container 44c.

Operation | movement of the vacuum cleaner comprised as mentioned above is demonstrated.
First, as shown in FIG. 1, the dust on the floor surface of the house is sucked from the suction tool 29 by the suction action generated by the electric blower 30, and the dust collecting case 24 passes through the suction hose 26 and the extension pipe 28. Air containing dust is introduced, the dust is centrifuged, and fine dust is filtered and collected. The filtered air is exhausted from an exhaust outlet (not shown) downstream of the electric blower 30 (a cyclonic vacuum cleaner).

  Next, the operation of the dust collecting case 24 will be described with reference to FIGS. First, the spring of the compression means 42 raises the compression plate 43 and stores it in the upper part of the dust collecting chamber 35. And the air containing the dust which flowed in from the air inlet 31 by the suction action of the electric blower 30 is ejected tangentially from the air inlet 31 to the primary swirl chamber 34 and slightly swirls around the exhaust pipe 36 and immediately turns into the primary swirl. It flows into the secondary swirl chamber 39 located below the chamber 34. Thereafter, the air that has flowed into the secondary swirl chamber 39 flows through the substantial center of the secondary swirl chamber 39 and the primary swirl chamber 34 to the ventilation portion 37.

  In particular, as shown in FIG. 4, the primary swirl chamber 34 and the dust collection chamber 35 are in a state of being shifted in parallel, but in the secondary swirl chamber 39, the swirling air reaches the upstream end of the wall 39a. Then, since the direction suddenly changes along the wall 39a, the dust contained in the air cannot go about the air that changes the direction, and jumps into the dust collecting chamber 35 from the inlet 40 due to the inertial force of the dust itself. .

  At that time, the swirling air flows along the outer peripheral side wall of the secondary swirl chamber 39, but the amount is small due to a slight dynamic pressure on the inlet 40, centrifugal force to the air, etc., but a part of the swirling air flows. It flows into the dust collecting chamber 35 from the inlet 40. In the dust collection chamber 35, the air immediately decelerates and slowly swirls in the dust collection chamber 35, and returns from the inlet 40 to the secondary swirl chamber 39. The dust flowing into the dust collection chamber 35 does not return to the secondary swirl chamber 39 from the inlet 40 due to the slowly swirling air, but is separated from the air by its own weight, and is usually fine dust from the bottom on the bottom of the dust collecting chamber 35. (Soil, sand, etc.) and coarse dust (cotton dust, etc.).

  On the other hand, the dust that has not jumped into the dust collection chamber 35 is blocked by the ventilation portion 37, and again gets into the centrifugal swirl airflow, jumps into the dust collection chamber 35 from the inlet 20, and accumulates on the bottom surface of the dust collection chamber 35. Thereafter, the swirling air from which the dust has been separated returns from the center of the secondary swirl chamber 39 to the primary swirl chamber 34 and is exhausted from the vent 37 to the outside.

  On the other hand, the dust that has not jumped into the dust collecting chamber 35 is blocked by the ventilation portion 37, is again caught in the centrifugal swirl air, eventually jumps into the dust collecting chamber 35 from the inlet 20, and accumulates on the bottom surface of the dust collecting chamber 35. Further, the air slowly turns in the dust collection chamber 35. In addition, air containing fine dust such as lint passes through the ventilation portion 37, but the fine dust is filtered by the second dust separation means 38, and the clean air passes through the second dust separation means 38. Then, the electric blower 30 is guided.

  At the same time, the electric blower 30 is deducted from room temperature by a temperature action of about 18K due to a cooling action by the passing air and a heating action by a temperature rise of a built-in motor (not shown). And the temperature of the 2nd container 44c and the humidity control container 44 which are closely_contact | adhered to the electric blower 30, the air of the inside, and the moisture absorption / desorption member 45 is raised.

  When the cleaning is completed, the electric blower 30 is stopped and the compression means 42 manually lowers the compression plate 43 to compress the dust accumulated in the dust collecting chamber 35 as shown in FIGS. Make it compact. At that time, the opening 41 is opened.

The electric blower 30 is no longer cooled by the passing air, and further rises in temperature by about 9K due to the residual heat (heat capacity) of the motor built in the electric blower 30. That is, the electric blower 30 continues to rise in temperature by about 18K or more for about one hour after the cleaning is completed.
Similarly, the humidity control container 44 is heated from the electric blower 30 and the temperature rises from about 24 ° C. to about 51 ° C.

  As shown in FIG. 8, the relative humidity around the moisture absorbing / releasing member 45 is reduced from 60% to 14% due to the temperature rise, and 2.4 g (10 g × 24) of steam with a difference of 24% from a moisture absorption rate of 48% to 14%. %) Is dehumidified. However, in actuality, it takes time for the moisture absorption / release member 45 to release moisture, and the vapor that has been released accumulates around the moisture absorption / release member 45. Since the relative humidity around the wet member 45 is not maintained at 14% and immediately rises, the hygroscopic member 45 releases 0.3 to 0.6 g according to normal experiments.

  Subsequently, the high-humidity, high-temperature air containing the steam released from the moisture absorption / desorption member 45 is transferred to the humidity control container 44 by the humidity difference (mass transfer) and the natural convection between the humidity control container 44 and the dust collection chamber 35. It passes through the upper part and flows into the dust collecting chamber 35 from the opening 41 through the communication pipe 48. The relative humidity of the dust collection chamber 35 increases by about 80 to 95%, and the temperature increases by about 1 to 5K.

  Next, high-humidity air accumulates in the dust collection chamber 35 through the gap between the dust collection chamber 35 and the compression plate 43 and humidifies the dust 3 g (standard daily dust) compressed in the compression plate 43. As a result, the dust absorbs about 0.1 g to 0.3 g over time from the high humidity air that permeates through the gap between the dust itself, so that the coarse dust (cotton dust etc.) is soft and easily deformed and has compressibility. The improved, deformed and elongated coarse dust is entangled with each other. Therefore, even if the compression means 42 is released, the compressed dust hardly returns to its original volume.

  On the other hand, fine dust (mud, sand, etc.) increases in weight and softens when it absorbs moisture, bonds with each other, and becomes entangled with the deformed coarse dust. In addition, once high-humidity air enters the dust collection chamber 35, a part of the air escapes from the inlet 40 to the secondary swirl chamber 39, but the dust collected in the dust collection chamber 35 and compressed by the compression plate 43 is still sufficient. Can absorb moisture.

  In addition, when the bottom cover of the dust collecting chamber 35 was opened in order to discard the compressed dust accumulated in the dust collecting chamber 35, the heavy fine dust accumulated in the bottom fell straight and was compressed on the top. Since the coarse dust falls, there is an effect that the scattering of dust can be suppressed.

  Then, the air whose humidity and temperature are lowered by applying humidity to the dust is pushed out of the dust collection chamber 35 and returns to the humidity control container 44 through the communication pipe 48 again, receives the humidity from the tuftic and receives the dust. Head to 35.

  When two hours or more have elapsed after the cleaning is completed, the temperature of the electric blower 30 and the humidity control container 44 is reduced to near room temperature due to heat radiation to the atmosphere. At that time, the moisture absorbing / releasing member 45 switches from the moisture releasing action to the moisture absorbing action of taking moisture away from the air in the dust collecting chamber 35 and the dust collecting case 24, and recovers to the original moisture absorbing state over time (approximately one day). Therefore, a water tank for moisture release is unnecessary.

At that time, moisture is also removed from the compressed dust and dried, but once the coarse dust is deformed, it is difficult to return to its original state like ironing, and the fine dust is tightened as hard as mud.
As a result, a large amount of dust can be stored in the dust collecting chamber 35 (the dust collecting chamber 35 can be made compact), and when the compressed dust collected in the dust collecting chamber 35 is discarded by opening the bottom cover, There is an effect that scattering is suppressed.

In addition, since the compressed dust is repeatedly absorbed and released every time it is cleaned, the moisture content of the dust is not significantly increased, the growth of bacteria, mold, etc. is suppressed, and the generation of odors can be prevented. It is possible to make it difficult for dust to adhere to the dust collection chamber 35. At this time, a part of the moisture that escapes from the dust passes through the communication pipe 48 and is absorbed by the moisture absorbing / releasing member 45. The time required for moisture absorption of the moisture absorbing / releasing member 45 is considered to be sufficient since it is until the next cleaning, that is, about one day.

  In this way, the humidity is humidified in the dust collection chamber 35 where the air flow is relatively slow, so that it can be supplied to the dust without being exhausted, and the highly humid air can be reliably sent to the dust. . Moreover, since the moisture absorption / desorption member 45 releases humidity by the heat of the electric blower 30 and the humidity is supplied from the air after the electric blower 30 is cooled, a power source for heating the moisture absorption / desorption member 45 becomes unnecessary, In addition, it is not necessary to supply water.

  Further, with such a configuration, the humidity control container 44 has the first container 44b and the second container 44c arranged with an elastic member 46 such as a vibration-proof rubber interposed therebetween, so that the operation of the electric blower 30 The vibration accompanying the vibration is transmitted to the second container 44c, but is not transmitted to the first container 44b due to the action of attenuating the vibration specific to the vibration isolating rubber of the elastic member 46. The vibration is not transmitted, and is not transmitted to the dust collection chamber 35 connected to the tip of the communication pipe 48 from the first container 44b.

  Moreover, since the electric blower 30 is attached to the cleaner body 21 via the outer peripheral support member 51 and the bottom support member 52, the electric blower 30 is not transmitted to the cleaner body 21.

  Therefore, the humidity control container 44 and the dust collection case 24 connected thereto do not vibrate and no unpleasant noise is generated. In addition, it is possible to provide a highly reliable vacuum cleaner in which the tuftic attached to the corrugated honeycomb as the moisture absorbing / releasing member 45 does not fall off due to vibration.

  Further, the moisture absorbing / releasing member 45 supplies high-humidity air to the dust collection chamber 35. As a result, the coarse dust is easily deformed, the compressibility is improved, and the dust collection chamber 35 can be greatly reduced in size. Since the power of the electric blower 30 and moisture in the air are used, it is not necessary to supply power and water, so that it is possible to provide a convenient vacuum cleaner.

  Therefore, it is possible to provide a highly reliable electric vacuum cleaner that achieves both heat reception from the electric blower and suppression of vibration associated with the rotation of the electric blower.

(Embodiment 2)
The electric vacuum cleaner in Embodiment 2 of this invention is demonstrated.
FIG. 9 is a side sectional view of the humidity control container of the electric vacuum cleaner showing the second embodiment of the present invention. Hereinafter, the same parts as those of the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

  The difference from the first embodiment is that the elastic member 46 sandwiched between the first container 44b and the second container 44c holds the moisture absorbing / releasing member 45.

The inner diameter dimension of the elastic member 46 is made tighter than the outer dimension of the moisture absorbing / releasing member 45, and the moisture absorbing / releasing member 45 is press-fitted and held inside the elastic member 46.
By doing in this way, the vibration accompanying the operation of the electric blower 30 is transmitted to the second container 44c, but the elastic member 46 absorbs the vibration, so that the first container 44b and the moisture absorption / desorption member 45 The vibration is not transmitted to the dust collecting chamber 35 connected to the tip of the communication pipe 48 from the first container 44b.

  Therefore, the humidity control container 44 and the dust collection case 24 connected thereto do not vibrate and no unpleasant noise is generated. In addition, it is possible to provide a highly reliable vacuum cleaner in which the tuftic attached to the corrugated honeycomb as the moisture absorbing / releasing member 45 does not fall off due to vibration.

  In addition, although the example which uses a vibration-proof rubber as an elastic member was shown, it is not restricted to this, For example, you may use sponge, alpha gel, etc. which are independent foaming and do not permeate | transmit air. Moreover, you may attenuate a vibration by arrange | positioning the thing which combined the spring and the damper as an elastic member between the 1st container and the 2nd container. In that case, the gap between the first container and the second container may be closed with a flexible sheet or the like so that the humidity inside the humidity control container does not escape.

  The same effect can be expected even when, for example, 20 g of high silica zeolite DDZ (manufactured by Showa Co., Ltd.) having a relative humidity of about 10% or less is used as the moisture absorbing / releasing member 45. Further, as the moisture absorbing / releasing member 45, about 20 g of silica gel (a moisture absorbing / releasing member of a type in which the relative humidity and the moisture absorption rate are approximately in direct proportion) may be used.

  As described above, the vacuum cleaner according to the present invention uses the heat of the exhaust air of the electric blower to heat the humidity control container that houses the moisture absorbing / releasing member, and further vibrates with the rotation operation of the electric blower. Providing a highly reliable electric vacuum cleaner in which the vibration of the electric blower 30 is not transmitted to the humidity control container 44 and no noise or moisture absorption / desorption member 45 is dropped off because it is not transmitted to the humidity control container and the dust collecting case. Can do.
