Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a dehumidifier, and more particularly to a dehumidifier that can be used in a narrow space.
[0002]
[Prior art]
Generally, a dehumidifier is an evaporator that cools and dehumidifies indoor air, a condenser that reheats indoor air cooled and dehumidified by an evaporator to dry air, a blower that sucks and exhausts indoor air, and a dehumidifier that uses an evaporator. A dehumidified water tank or the like for storing the moisture in the indoor air is stored in the main body case, and an intake port for sucking indoor air and an outlet for discharging dry air dehumidified in the machine are formed in the main body case. ing.
[0003]
The dehumidifier having such a configuration is installed at one corner of the room for the purpose of dehumidifying the entire room, or is installed near the object so as to blow dry air on a specific object to be dried. It is used by being installed in a narrow space such as a narrow closet. The moisture in the room air dehumidified by the evaporator is stored in a dehumidified water tank, and the dehumidified water tank is taken out and drained in a timely manner.
[0004]
Moreover, the conventional dehumidifier is generally provided with an intake port on the front surface, and has a large width dimension and a small depth dimension (front-rear direction dimension) as viewed from the front.
[0005]
However, in the case of a dehumidifier with a large width as viewed from the front, when the dehumidifier is installed in a narrow space such as a closet or a gap between furniture and furniture, the futon and furniture in the closet The problem was that it was difficult to operate the machine and drain the dehumidified water with these futons and furniture.
[0006]
As a dehumidifier described in Japanese Patent Application Laid-Open No. 2000-220867 as a solution to such a problem, the external shape of the dehumidifier is reduced in the width dimension viewed from the front, and the dimension in the front-rear direction is increased. In addition, the air inlets are provided on the front surface portion and the rear surface portion, and the air outlets are provided on the upper surface portion. Also, the dehumidified water tank can be pulled out from the front.
[0007]
[Problems to be solved by the invention]
Although this conventional dehumidifier makes it easy to install in a narrow space, since there is only one outlet, it is difficult to efficiently blow dry air that has been dehumidified against a dry symmetrical object. .
Therefore, as a proposal to solve this, it is conceivable to provide a lower outlet, for example, on the side of the main body case whose dimensions in the front-rear direction are increased as described above. However, even if such a blowout port is provided on the side surface, as long as a conventional blowout louver, that is, a blowout louver that changes the blowing direction of air by rotating a plurality of or one louver, is used as follows. There seems to be a problem.
[0008]
First, considering the case of a blowout louver that changes the air blowing direction by rotating a plurality of louvers, it is necessary to fiddle with multiple louvers in a narrow space on the side of the dehumidifier. It seems difficult to do. In addition, it is possible to electrically operate such a plurality of louvers as a motor drive, but in this case, there is a problem that the structure becomes complicated and the cost is increased.
On the other hand, considering the case of a blowout louver that changes the air blowout direction by rotating one louver, it is easier to search for the louver in a narrow space than in the former case, Since there is only one louver, the space required to rotate the louver increases. For this reason, if it is going to make the width dimension of a dehumidifier small, it must be comprised so that a part of louver may protrude from a main body case at the time of opening. However, with this configuration, when carrying out the dehumidifier, there may be problems such as the protruding portion of the louver being on another object or a part of the body being caught. Furthermore, when installed in a narrow space, the protruding louver may be an obstacle.
[0009]
The present invention solves such a problem in the prior art, and includes a main body case formed elongated in the front-rear direction, and a dehumidifier provided with an air outlet on a side surface of the main body case. An object of the present invention is to provide a dehumidifier that can be easily used in a narrow space by avoiding the protrusion of the louver and facilitating the groping operation of the louver.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, a dehumidifier according to the present invention includes a main body case formed elongated in the front-rear direction, and a refrigeration cycle component device such as an evaporator, a condenser, and a compressor for dehumidifying indoor air. A dehumidified water tank which is stored in a lower part of the main body case so as to be pulled out from the front, stores the dehumidified water tank dehumidified by the evaporator, an outlet provided on the side of the main body case, and room air. And a blower in which a blow-out passage is connected to a blow-out port so as to supply and exhaust air. The blower is divided into an upper blower fan housing and a lower blower fan housing at a predetermined position in the rotation axis direction. The upper and lower outlet type sirocco fan, the outlet is provided below the side surface of the main body case, and is connected to the outlet passage of the lower outlet fan housing. The upper air outlet has an upper air outlet, and the upper air outlet is connected to the air outlet passage of the upper air outlet fan housing, and the air outlet is slid by an operation knob protruding to the side of the main body case. A louver that moves up and down is provided, and an up-and-down slide-type opening / closing lid device that can open and close the opening and change the opening degree in a plurality of stages by operating the operation knob up and down is provided .
[0011]
If comprised in this way, when it is a case where a dehumidifier is installed in the narrow space and it opens and closes a blower outlet or changes an opening degree, it only needs to move the operation knob of an up-and-down slide type opening-and-closing lid device up and down. Therefore, the groping operation from the front can be performed relatively easily. In addition, since the louver slides up and down by moving the operation knob up and down, the position of the operation knob is proportional to the opening, and how much is the opening even in groping Can be easily determined. Further, since the blowout louver does not protrude forward of the main body case, the louver does not get in the way when carrying the dehumidifier or installing the dehumidifier in a narrow place. In addition, the operation knob for moving the louver up and down protrudes from the main body case, but this operation knob does not need to protrude over the entire width of the louver, and it can be small, so it is obstructive as if the louver protrudes is not. Moreover, it will have a blower outlet up and down, and can dry air to a target object from various directions.
[0012]
The vertical slide type opening / closing lid device includes a louver having a substantially flat lid portion, a guide shaft protruding from the upper and lower sides of the left and right side surfaces of the louver, and guide holes for guiding the guide shaft in the vertical direction. A guide plate provided on the left and right sides of the air outlet, and a cantilevered support on the back surface of the louver, and formed so as to be elastically deformable in the vertical direction when a vertical force is applied to the tip. An elastic member, and a position holding member provided with a position control surface that causes a frictional force that elastically deforms the elastic member in the vertical direction when operated so as to move the louver in the vertical direction; The position holding member may have a position holding recess formed at a plurality of positions on the position control surface of the position holding member and fitting the tip of the elastic member.
When configured in this way, the louver can easily fall due to the frictional force between the tip of the elastic member and the position control surface, regardless of where the hand is released from the operation knob when the louver is operated up and down. There is no such thing. In addition, since the force that moves up and down changes when the tip of the elastic member is fitted in the position holding recess, even in the groping operation, the opening holding position is set in steps. It can be easily detected by touch of the hand. Further, since the position holding recesses need only be formed on the position control surface, the number, position, etc. of the position holding recesses can be easily set and formed.
[0013]
Further, the position holding member may be formed by a plate-like member standing on the inner wall surface of the outlet passage, and an end surface of the plate-like member may be formed as a position control surface.
If comprised in this way, a position holding member can be combined with the baffle plate for equalizing the airflow distribution of a blower outlet.
[0015]

The upper outlet 2 is communicated with an upper blowing fan housing 10a of the blower 8, and the lower outlet 6 is communicated with a lower blowing fan housing 10b of the blower 8.
[0019]
Moreover, as shown in FIG.3 and FIG.4, the refrigeration cycle is comprised with the evaporator 6 and the condenser 7 in the lower side in the main body case 1 and the rear side (lower left side of FIG. 3) in the main body case 1. A compressor 13 and an accumulator 14 are attached, and a dehumidified water tank 15 for storing dehumidified water that is condensed and dripped by the evaporator 6 is disposed on the front side (lower right side in FIG. 3) in the main body case 1.
[0020]
The dehumidified water tank 15 is detachably accommodated in the main body case 1 in a pull-out manner from the front surface of the machine main body, and the front side portion is exposed outside the main body case 1 in the accommodated state. This exposed portion forms part of the outer contour of the machine body.
[0021]
An ultraviolet lamp unit 16 is incorporated on the inner surface side of the front portion of the upper part of the main body case 1. Further, a front cover 17 is detachably attached to the front side of the ultraviolet lamp unit 16 in the machine body.
[0022]
The front cover 17 forms part of the outer contour of the machine body. Further, the front cover 17 is attached so that a gap is formed between both ends of the front cover 17 and the main body case 1 at the narrow front portion of the main body case 1. And this clearance gap is formed as the narrow inlets 21 and 22 which suck | inhale air.

[0023]
In addition to the intake ports 21 and 22, the intake port of the dehumidifier according to the present embodiment extends from the rear surface of the narrow portion in the rear portion of the main body case 1 to the right side surface portion, as can be seen from FIG. A formed air inlet 25 is provided. Further, the air sucked from the intake port 25 is configured to be taken into the machine via an air filter 26 provided at the intake port 25.
[0024]
Next, the detailed structure of the above-described vertical slide type opening / closing lid device will be described.
FIG. 5 is a perspective view of the louver 31 attached to the lower outlet 3. The louver 31 has side plate portions 33 on both left and right sides of a substantially flat lid portion 32, and guide shafts 34 and 35 on the upper and lower sides of the side plate portion 33. An operation knob 36 protruding from the main body case 1 is formed below the front surface of the lid portion 32.
[0025]
FIG. 6 is a perspective view around the lower outlet 3 when the left side surface portion of the main body case 1 is viewed from the inner surface side. As shown in FIG. 6, on the back surface of the left side plate portion of the main body case 1, guide holes 41 for guiding the guide shafts 34, 35 of the louver 31 to move up and down at predetermined positions on both sides of the lower outlet 3. , 42 are provided upright. The louver 31 is attached by inserting the upper guide shaft 35 into the upper guide hole 42 and inserting the lower guide shaft 34 into the lower guide hole 41. Further, by moving the operation knob 36 up and down, the lower guide shaft 34 is guided in the lower guide hole 41 and the upper guide shaft 35 is guided in the upper guide hole 42 so that the louver 31 can be moved up and down. It is configured. In this movement, the angle at which the louver 31 is moved and fixed is determined by the hole design of the guide holes 41 and 42. In the case of the present embodiment, the lower air outlet 3 is opened while moving the upper end of the lid 32 backward.
[0026]
Next, FIG. 7 is a perspective view from the left side of the lower blowing fan housing 10b. FIG. 8 is a view showing a relationship between the louver 31 attached to the lower outlet 3 and the position holding member 61, and FIG. 9 is a view for explaining a position holding mechanism of the louver 31 by the position holding member 61. . As shown in these drawings, on the back side of the lid portion 32, an elastic member 51 in which a spring plate member having a small width is bent in a meandering manner in the vertical direction is supported in a cantilever manner. And the front-end | tip part 52 of the elastic member 51 supported by this cantilever type is formed so that it may become roundish. Further, the front end 52 of the elastic member 51 is pressed against the position control surface 62 of the position holding member 61 attached to the inner wall surface of the blowout passage of the lower blowout fan housing 10b, and the front end 52 is elastically deformed upward or downward. The position and shape of the position control surface 62 are set so as to come into contact with each other. That is, when the louver 31 moves upward, the tip 52 is slightly deformed downward due to the frictional force between the tip 52 and the position control surface 62. Conversely, when the louver 31 moves downward, Due to the frictional force between the tip 52 and the position control surface 62, the tip 52 is slightly deformed upward.
[0027]
The position holding member 61 is a member in which a metal plate member is fixed so as to be perpendicular to the inner wall surface of the lower blowing fan housing 10b, and its end side end surface is provided with the position and shape as described above. It is configured as a control surface 62. That is, the position control surface 62 is configured to follow a locus caused by the movement of the distal end portion 52 so that a constant frictional force is applied to the distal end portion 52 of the elastic member 51. Further, the position control surface 62 stably holds the position holding recesses 63 and 64 for stably holding the louver 31 at the lowest holding position and the highest holding position and the louver 31 at an appropriate intermediate position. Position holding recesses 65 and 66 are provided. That is, when the distal end portion 52 of the elastic member 51 moves to the position holding recesses 63, 64, 65, and 66, the distal end portion 52 extends while the elastically deformed elastic member 51 is restored to the natural state. It fits in these position holding recesses 63, 64, 65, 66, and holds the louver 31 stably at a predetermined position.
[0028]
Since the position holding member 61 is a metal plate member fixed so as to be perpendicular to the inner wall surface of the lower blowing fan housing 10b, the lower blowing fan can be adjusted by appropriately adjusting the planar shape. The air flow in the housing can be rectified and function as a rectifying plate for uniforming the wind speed distribution at the outlet.
[0029]
As described above, the dehumidifier according to the present embodiment has a small width as viewed from the front and a large size in the front-rear direction, so that it can be installed in a narrow place such as a closet. In this case, since the dehumidified water tank can be drawn out from the front surface, when the dehumidified water is drained, it is not necessary to drag out the machine body, and only the dehumidified water tank needs to be pulled out to the front side. Moreover, since the upper blower outlet 2 and the lower blower outlet 3 are provided as a blower outlet, dry air can be blown off in multiple directions, and a multi-directional drying object can be efficiently dried.
[0030]
In addition, when the dehumidifier according to the present embodiment is installed in a narrow place such as a closet, when it is desired to blow the dry air to the left side and dry the object on the left side, the slide The lower air outlet 3 can be opened by operating the open / close lid device (state shown in FIG. 9D). Further, when there is no object to be dried on the left side, the lower air outlet 3 can be closed by operating the sliding opening / closing lid device (state shown in FIG. 9A). If the amount of blowout from the lower outlet 3 to the lower part is desired to be reduced depending on the type or state of the object to be dried on the left side, the louver 31 is adjusted to the intermediate opening state by operating the sliding opening / closing lid device. (The state shown in FIG. 9 (b) or (c)).
[0031]
The operation of the sliding opening / closing lid device can be easily performed even when there is no large space on the left side. In other words, when there is no large space on the left side, the user can move the operation knob 36 up and down even if the user extends his hand from the front and is in a groping state. Further, the operation position of the operation knob 36 is the lowest holding position (the state shown in FIG. 9A), the highest holding position (the state shown in FIG. 9D), or the intermediate holding position (FIG. 9B or FIG. 9C). ), The force required for operation changes when the tip 52 of the elastic member 51 is fitted into the position holding recesses 63, 64, 65, 66. You can know this more easily. Further, even if the operation knob 36 is released at a position other than the holding position, the operation knob 36 is held on the spot by the frictional force between the tip 52 and the position control surface 62, so that the operation becomes very easy. Moreover, since it is a slide-type opening / closing lid device, the position of the operation knob 36 and the opening degree are substantially proportional, and it is possible to easily determine the opening degree.
[0032]
Moreover, in the dehumidifier which concerns on this Embodiment, since there is no protrusion of the horizontal blade | wing used as a baffle from the lower blower outlet 3, it is convenient when installing in a narrow place or carrying a dehumidifier. An operation knob 36 for moving the slide-type opening / closing lid device up and down protrudes from the main body case 1. However, the operation knob 36 does not need to protrude over the entire width of the lower outlet 3 and may be small so that it is almost in the way. Don't be.
[0033]
Further, since the position holding member 61 constituting the position control surface 62 is formed by a plate-like member standing upright to be perpendicular to the inner wall surface of the lower blowing fan housing 10b, the position holding member is blown. It can also be used as a current plate that equalizes the air volume distribution at the outlet.
[0034]
【The invention's effect】
Since this invention is comprised as mentioned above, there can exist the following effects.
According to the first aspect of the present invention, by operating the operation knob that protrudes to the side of the main body case up and down, the louver can be slid up and down so that the air outlet can be opened and closed or the degree of opening can be changed in multiple stages. Thus, even if the dehumidifier is installed in a narrow place, it can be easily operated by a groping operation from the front. In addition, since the louver slides up and down by moving the operation knob up and down, the position of the operation knob is proportional to the opening, so how much opening is possible even in groping It can be easily determined whether or not there is. Moreover, since the blowing louver does not protrude forward of the main body case, the louver does not get in the way when carrying the dehumidifier. Moreover, it will have a blower outlet up and down, and can dry air to a target object from various directions.
[0035]
According to the second aspect of the present invention, the louver can be opened and closed by sliding the guide shaft of the louver in the guide hole, and an elastic member is attached to the back surface of the louver, and the tip of the elastic member Since the part is elastically in contact with the position adjustment surface with the position holding recess of the position holding member, the louver can be easily moved from the operation knob at any position when the louver is operated up and down. There is no such thing as falling down. In addition, since the force that moves up and down changes when the tip of the elastic member is fitted in the position holding recess, even in the groping operation, the opening holding position is set in steps. It can be easily detected by touch of the hand. In addition, since the position holding recesses need only be provided on the position adjustment surface, the number and positions of the position holding recesses can be easily set and formed.
[0036]
According to a third aspect of the present invention, the position holding member is formed by a plate-like member that is erected so as to be perpendicular to the inner wall surface of the blowing passage, and the end surface of the plate-like member is position-controlled. Since it forms as a surface, a position holding member can be combined with the baffle plate which equalizes the airflow distribution of a blower outlet.
