Description

humidifier

technical field

The present invention relates to humidifying devices.

Background technique

The vaporization type humidifier performs humidification by ventilating a humidification filter immersed in water stored in a water storage container. That is, the vaporization type humidifier humidifies the air sucked in from the outside and discharges it as humidified air. Therefore, the humidifier has a suction port for sucking in air.

Conventional humidifiers have suction ports partially on the sides (see JP-A-11-23021, JP-A 2004-44904, and JP-A-2011-21797). For this existing humidifying device, due to design limitations, its suction ports are all arranged in an inconspicuous area on the side.

Contents of the invention

In the prior art, the suction port is provided with a prefilter (prefilter) for trapping dust and the like. For the pre-filter, it needs to be disassembled separately from the water storage container and the humidification filter for cleaning. Therefore, the work of cleaning the pre-filter of the suction port is a troublesome operation, and it tends to be cleaned infrequently. As a result, there is a problem that the humidification capability is reduced due to clogging of the pre-filter.

Therefore, an object of the present invention is to provide a humidifier having an easy-to-clean pre-filter that increases the degree of freedom in the location of the suction port.

Therefore, the humidifier of the present invention includes a blower unit, a humidification filter, and a water storage container. The humidification filter holds the filter at a predetermined position in the water storage container through the holder. filter.

Since the pre-filter is provided on the holder holding the filter of the humidification filter, air taken in from any direction passes through the pre-filter before coming into contact with the filter. Therefore, the degree of freedom in the position where the suction port is provided increases.

Detailed ways

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(implementation mode)

FIG. 1 is a perspective view of a humidifier according to an embodiment of the present invention viewed from an oblique front upper side, and FIG. 2 is a cross-sectional view taken along a plane A in FIG. 1 . As shown in FIGS. 1 and 2 , the humidifier 1 includes a blower unit 2 , a humidification filter 3 , and a water storage container 4 inside. In addition, the humidifier 1 further includes a main body case 7 provided with the first outlet 6 on the top surface 5 , and an airflow direction changing part 8 that changes the blowing direction of the humidified air from the first outlet 6 . Here, the main body cover 7 includes the ventilation part 2, the water storage tank 4, and the humidification filter 3 inside. Moreover, the wind direction changing part 8 has the 2nd blower port 9 which blows out the humidified air to an outer direction.

3 is a perspective view of the water storage container viewed from an oblique front upper side in a state in which the humidification filter of the humidifier according to the embodiment of the present invention is fixed. The humidification filter 3 holds the filter element 32 in the water storage container 4 via the holder 31 . The holder 31 has a pre-filter 33 . Furthermore, a pre-filter 33 surrounds the periphery of the filter element 32 . Therefore, as shown in FIG. 2 , dust and the like can be removed from the outside air sucked by the first suction port 71 of the main body cover 7 and the second suction port 41 of the water storage container 4 by the pre-filter 33 . And the air which has passed through the pre-filter 33 becomes the humidified air by passing the filter 32 which one end soaked in the water in the water storage container 4 in the state which absorbed water. This humidified air is blown out from the air outlet 9 through the air blower 2 to the outside.

The pre-filter 33 is composed of components generally used to filter dust and dust in the air. As such a member, for example, a mesh made of metal, resin, chemical fiber, or the like can be used.

Fig. 4 is an exploded perspective view showing a state in which the humidification filter is detached from the humidifier according to the embodiment of the present invention and disassembled into a filter and a holder. As shown in FIG. 4, the filter element 32 is cylindrical. The pre-filter 33 provided on the outer surface of the holder 31 surrounds the outer surface side of the filter element 32 . In addition, the holder 31 has a partition plate 34 that partitions the outside of the pre-filter 33 from the water storage portion 42 of the water storage container 4 .

With these structures, as shown in FIG. 2 , the air sucked from the first suction port 71 and the second suction port 41 does not directly reach the filter element 32 without passing through the pre-filter 33 . That is, the air sucked in from any part of the main body cover 7 always passes through the pre-filter 33 . Therefore, the degree of freedom of the positions where the first suction port 71 and the second suction port 41 are provided in the main body cover 7 is increased.

As shown in FIG. 2 , the partition plate 34 is provided slightly above the full water position F of the upper end of the water storage portion 42 of the water storage container 4 . Therefore, since the humidification filter 3 is transported in a state attached to the water storage container 4 , water does not spill from the water storage container 4 . That is, by covering the partition plate 34 between the pre-filter 33 and the water storage container 4 , waves generated near the edge due to the shaking of the water storage container 4 are eliminated, so that water does not spill from the water storage container 4 .

FIG. 5 is a bottom view (bottom view) of the humidifier according to the embodiment of the present invention, viewed from the bottom surface 72 . As shown in FIG. 3 , the outer surface side of the filter element 32 is surrounded by a pre-filter 33 . Therefore, no matter which direction the air is sucked in, it passes through the pre-filter 33 . Thereby, as shown in FIG. 5 , in the humidifier 1 , in addition to providing the water storage portion 42 on the back side of the main body, air is sucked into the main body cover 7 from the first suction port 71 . The main body cover 7 includes an edge portion (skirt, baffle portion, skirt portion) 73 . Moreover, the 1st suction port 71 is provided in the lower surface 73a of the edge part 73. As shown in FIG. Here, "the lower side surface 73a of the edge part 73" means the surface which faces downward so that the normal line of the lower side surface 73a of the edge part 73 may intersect a horizontal line.

In a conventional humidifier, a pre-filter for removing dust, dust, and the like is provided at the suction port. In addition, in order not to impair the appearance of the humidifier, the suction port is usually provided only on the back side. If only the suction port is provided on the back as in the prior art, the velocity of the air passing through the filter in the main body cover will become uneven.

In the humidifier 1 of the present embodiment, since the filter 32 is surrounded by the pre-filter 33 of the holder 31 as shown in FIG. 3 , it is not necessary to provide a filter at the air suction port. Therefore, the degree of freedom of the shape and the position of the first suction port 71 and the second suction port 41 is improved. As shown in FIG. .

By taking in air from the first suction port 71 and the second suction port 41, the velocity of the air passing through the filter 32 becomes uniform as shown in FIG. As a result, since the humidification efficiency by the humidification filter 3 improves, the humidification filter 3 becomes small and the humidification apparatus 1 can be miniaturized.

Moreover, the 1st suction port 71 is provided in the side of the lower surface 73a of the edge part 73 which a user hardly sees in a normal use state. In this way, the design of the humidifier 1 is improved by arranging the first suction port 71 , which is one factor that affects the appearance, at a position that is difficult for the user to see.

Next, as shown in FIG. 2 , in the humidifier 1 , since the lower surface 73 a of the edge portion 73 faces the horizontal plane, the sound from the first suction port 71 is emitted downward. Accordingly, the sound from the first suction port 71 is reduced for the user's sense of hearing. Noise caused by suction can be suppressed compared to conventional humidifiers in which the suction port is provided on the side.

6 is a perspective view of the water storage container viewed from an oblique front upper side in a state where the humidification filter is fixed to the water storage container of the humidifier according to the embodiment of the present invention. As shown in FIG. 2 , in the humidification filter 3 , the partition plate 34 is provided outside the pre-filter 33 . Therefore, as shown in FIG. 6 , the vicinity of the edge of the water storage container 4 is covered by the partition plate 34 in a state where the holder 31 is attached to the upper end of the edge of the water storage container 4 via the locking portion 36 . Therefore, when water is supplied to water storage container 4 with humidification filter 3 attached, it is difficult for the operator to recognize the relationship between the upper end of water storage portion 42 of water storage container 4 and the water surface.

Then, as shown in FIGS. 2 and 6 , the holder 31 of the humidification filter 3 has a water level display portion 35 at a height at which the water storage portion 42 is filled with water. As a result, the operator can easily recognize that the water storage part 42 is full when the water surface reaches the water level display part 35 provided on the inner surface 32 a of the filter material 32 . In order to indicate the function of the water level display part 35 , for example, it is only necessary to mark the surface of the water level display part 35 with signs such as "full water" and "stop here".

Fig. 7A is a side view showing a state where the second main body cover is attached to the first main body cover of the humidifier according to the embodiment of the present invention, and Fig. 7B is a side view showing the second main body cover detached from the first main body cover of the same humidifying device. State side view. As shown in FIG. 2, FIG. 7A, and FIG. 7B, the main body cover 7 is comprised from the 1st main body cover 7a which has the air blower part 2, and the 2nd main body cover 7b. Here, the 2nd main body cover 7b which integrated the humidification filter 3 and the water storage container 4 is attachable and detachable with respect to the 1st main body cover 7a.

As shown in FIG. 7A, the second main body cover 7b is attached to the first main body cover 7a when the humidifier 1 is used. In addition, as shown in FIG. 7B , when water is supplied to the water storage container 4 , the second body cover 7 b is detached from the first body cover 71 . As a result, the humidification filter 3 and the water storage container 4 are also detached from the 1st main body cover 7a together with the 2nd main body cover 7b. Therefore, the parts that tend to be stained with the use of the humidifier 1 are also detached, and can be kept clean by performing maintenance.

Conventionally, a tank for water supply is provided separately from a water storage container storing water soaked in one end of the humidification filter. In this configuration, when there is no water in the water storage container, only the water supply tank is detached, and the water supply tank already filled with water is attached to perform water supply. In this case, the operation of detaching the part including the water storage container and the humidification filter in the lower part of the main body (hereinafter appropriately referred to as “humidification unit”) is a troublesome and time-consuming work. Therefore, it is generally not necessary to disassemble the humidifying part together for cleaning during normal water supply.

In addition, in the prior art, a pre-filter for removing dust and dust from the air taken in from the suction port is provided at the suction port on the side of the main body cover. Therefore, in order to clean the pre-filter, in addition to the operation of removing the humidifier, the operation of removing the pre-filter from the suction port is also required.

As described above, in the prior art, in order to clean the humidifier and the pre-filter, it is necessary to disassemble them separately. In addition, since these operations are cumbersome, the cleaning of the humidifying unit and the pre-filter is infrequent, and this becomes a cause of performance degradation of the humidifying device.

On the contrary, as shown in FIG. 2, FIG. 7A, and FIG. 7B, for the main body cover 7 of the humidifier 1, the water storage container 4 is integrally formed on the second main body cover 7b, and the humidification filter 3 is detachable. The state is fixed to the water storage container 4 . Therefore, the humidification filter 3 and the water storage container 4 can also be detached simultaneously by detaching the 2nd main body cover 7b.

In addition, the humidification filter 3 is provided with a pre-filter 33 . Therefore, when water is supplied to the water storage container 4, when the second body cover 7b is removed from the first body cover 7a, the pre-filter 33 is also removed at the same time.

As described above, when water supply is performed, the parts that need to be kept clean are disassembled as a whole. Therefore, it is possible to perform cleaning operations on them so as not to cause stains and clogging, that is, maintenance for suppressing performance degradation of the humidifier 1 can be facilitated.

As shown in FIG. 8 , the second main body cover 7 b includes a handle portion 74 rotatably supported by the water storage container 4 . The handle part 74 which turns around the water storage container 4 is comprised by the part of the 2nd main body cover 7b. Both ends of the handle portion 74 are supported by the water storage container 4 via a rotation shaft 76 . Therefore, in a state where the second main body cover 7b is detached from the first main body cover 7a as shown in FIG. 7B , the handle portion 74 can be erected as shown in FIG. 8 for carrying the water storage container 4 .

As shown in FIG. 7B , the second main body cover 7 b which is a part of the main body cover 7 is detached integrally with the humidification filter 3 and the water storage container 4 . Thus, cleaning becomes easier since parts that are prone to getting dirty are disassembled together. Moreover, as shown in FIG. 8, the part of the 2nd main body cover 7b is used as the handle part 74, and by this, the conveyance at the time of water supply becomes easier. In addition, with respect to the water supply to the water storage container 4, you may supply it with the water conveyed by another container, instead of conveying the 2nd main body cover 7b.

In addition, as shown in FIG. 7B , the second main body cover 7 b has a notch 75 . Part of the water storage container 4 is exposed to the outside 77 through the notch 75 . In addition, the water storage container 4 has an outer surface portion 43 formed as a continuous surface with the outer surface 7c of the main body cover 7 at a portion exposed to the outside 77 from the notch portion 75, and a portion whose upper end is positioned higher than the notch portion 75. Recess 44 . A gap 78 is formed between the concave portion 44 and the second main body cover 7b.

Part of the water storage container 4 is an outer surface portion 43 formed in a shape continuous with the outer surface of the main body cover 7 , thereby increasing the capacity of the water storage portion 42 of the water storage container 4 . Moreover, by providing the recessed part 44, a hand can be inserted into the recessed part 44, and the 2nd main body cover 7b can be pulled out easily from the 1st main body cover 7a.

Fig. 9 is a rear view of a second body cover of the humidifier according to the embodiment of the present invention. As shown in FIG. 9 , the recess 44 of the water storage container 4 has a second suction port 41 for sucking air into the main body cover 7 . By providing the second suction port 41 in the concave portion 44 recessed from the surface of the main body cover 7, the second suction port 41 is not conspicuous, and the noise generated by suction is also reduced.

In addition, the second suction port 41 has a lattice shape in which the grooves 79 are arranged in the vertical direction as the longitudinal direction. Therefore, when the second main body cover 7b shown in FIG. 7B is detached from the first main body cover 7a, when the hand is stretched into the recess 44, the nail will not be stuck in the second suction port 41, so that it can be smoothly The second main body cover 7b is detached.
