And

[0007]

The dehumidifier of the present invention (claim 1) has a built-in refrigeration cycle including a compressor, a condenser, an evaporator, a blower fan and the like in a main body, and is formed in the main body. In a dehumidifier that discharges and blows air by contacting the indoor air that flows from the intake port toward the exhaust port with the evaporator and the condenser, and dehumidifies and dries the air, the main body is configured to be elongated. Provided at the top of the front surface of the main body, which is installed at the time of use so that the direction is forward and backward, and the exhaust port is provided at the top surface of the main body, and a ventilation path from the intake port to the exhaust port is formed at the top inside the main body. In the ventilation path, the evaporator, the condenser and the ventilation fan are sequentially arranged so as to form a line in the left-right direction of the main body. Ta Provided click, the said body lower rear in which was allowed positioning the compressor.

Further, in the present invention (claim 2), the dehumidifier is provided with an intake port also in the rear surface of the main body having a long and narrow configuration.

Further, in the present invention (claim 3), the air passage provided in the main body of the dehumidifier removes room air entering from the front surface of the main body through the intake port of the main body orthogonal to the front-rear direction of the main body. The direction is changed at right angles to the left and right, and the air is allowed to flow through the evaporator and the condenser completely. After passing through the evaporator and the condenser, the direction of the air is changed vertically upward and the air is blown out from the exhaust port. This is a bent air path structure.

[0010] In the present invention (claim 4), the dehumidifier includes a rear surface of a main body provided with a rear intake port.
A protruding portion is provided between the rear portion of the main body and the inner wall of the installation location to secure a space for intake.

According to the present invention (claim 5), the dehumidifier is formed such that its intake port is recessed from the outer surface of the case of the main body.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

1 is a dehumidifier body (hereinafter abbreviated as “body”).
The outer surface of the main body is covered with a main body case 4 composed of a left case 2 and a right case 3 made of a synthetic resin. Reference numeral 5 denotes four peripheral sides of the main body case 4,
Of the grilles 7, 8, and 9, an intake port of a grill structure formed on a surface with a smaller area, and 10 is another grill structure formed on the other surface facing the intake port 5. One inlet.

Here, the front-back surface of the main body 1 refers to the surface on which the air inlet 5 is provided, that is, the front surface 6.
And rear face 7. The main body 1 has a configuration in which the length in the left-right direction is shorter than the length in the front-rear direction.
That is, as shown in FIG. 2, it has a configuration elongated in the front-rear direction. The intake port 5 is formed on the front surface 6 of the main body 1, and another intake port 10 is formed on the rear surface 7 of the main body 1.

In FIG. 2, in the left case 2 and the right case 3, the respective side surfaces 8, 9 without the intake ports 5, 10 become the left and right side surfaces of the main body 1, and this direction means the main body width. Conventionally, a dehumidifier having a structure in which the main body is long in the width direction of the main body has been mainly used. It has a structure in which the dimensional relationship is opposite to that of the conventional dehumidifier, and is short (thin) in the width direction of the main body as shown in FIGS. As a dehumidifier, the air inlet 5 is disposed in the narrow space 14 between the bedding 12 and the inner wall 13 as shown in FIG. ing.
As a result, the air inlets 5 and 10 are not located on the side surfaces as in the related art, so that the air inlets 5 and 10 are not blocked by the futon 12.

In the embodiment, the intake ports 5 and 10 are two intake ports provided one by one on the front and rear surfaces 6 and 7 of the main body. However, two intake ports are not necessarily required. However, any configuration provided may be used.

Reference numeral 15 denotes a protruding portion formed at the rear of the dehumidifier so as to secure a suction space.
When the dehumidifier is installed in the push-in 11, the installation in a state where the rear intake port 10 is pushed in so as to be in close contact with the back wall (not shown) and closed is prevented. The rear part is set slightly away from the inner wall of the push-in, and a proper space is always secured between the rear part of the main body and the inner wall of the push-in, thereby ensuring smooth air suction from the inlet 10. .

The projecting portion 15 can be a projection formed integrally with the main body case 4. The position of the protrusion (projection for securing the intake space) 15 may be anywhere on the rear surface of the main body case 4 and the number thereof is not limited. With this arrangement, the dehumidifier can be installed stably with a certain gap secured behind the main body. The protruding portion 15 for securing the intake space is not required when the intake port is provided only on the front surface of the main body and not on the rear surface.

Incidentally, the suction port 5 formed on the front surface of the main body 1 is formed so as to be slightly recessed from the outer surface of the main body case 4 without being flush with the outer surface of the main body case 4. This is because, when the dehumidifier is installed in a closet, for example, and the door of the closet is closed and used at last, if the dehumidifier is kept as it is, the door comes into close contact with the suction port 5 and the suction performance from the front is deteriorated. Since the suction port 5 having the recessed 35 configuration has suction openings on the left and right sides of the suction port 5, air can be sucked from the side (lateral direction) instead of forward. It is intended to secure the ventilation rate. In addition, in this way, the suction port 5 having the concave 35 can expect the effect of increasing the suction air and increasing the suction rate. In addition, the intake port 5 has a part 35 recessed.
The airflow rate can be sufficiently secured by
It is also possible to adopt a configuration in which the whole is uniformly depressed.

This measure for recessing the suction port can be used in place of the above-mentioned protrusion 15 which fulfills its function when securing a suction space at the rear of the dehumidifier. That is, as shown in the front intake port 5, the rear intake port 10 is formed so that the intake port 10 is not flush with the outer surface of the main body case 4 but is slightly recessed from the outer surface of the main body case. What should I do? With this, even if the suction port 10 is in a state where the suction port 10 is pressed into close contact with the inner wall, suction from the front (rear face) becomes insufficient.
There is an opening for suction on both sides on the left and right, so that air can be sucked from the side from there, without reducing the suction rate, it is possible to maintain the required ventilation volume, and it is effective is there.

Reference numeral 16 denotes an exhaust port, which is formed at a position behind the upper surface 17 of the main body as shown in FIG. On the upper surface 17 of the main body, an operation section 18 is formed on the front side of a portion located on the opposite side to the exhaust port 16, and an operation switch 19 and the like are provided there. Thereby, when the dehumidifier is installed, the operation switch 19 is also on the front side, so that the switch operation becomes easy, and the operability and usability are improved.

An air passage 20 is formed in the upper part of the main body 1 so as to extend from the intake ports 5 and 10 at the front and rear of the main body to the exhaust port 16 in the upper part of the main body. , Compressor 21 and condenser 2
2, an evaporator 23, a capillary tube (not shown), a blower fan 24, a fan motor 25 for rotating the blower fan 24, and the like. And the air passage 2
0, among the components of the refrigeration cycle, the condenser 22,
The evaporator 23 and the blower fan 24 are housed therein,
The evaporator 23 and the condenser 22 are arranged in the air passage 20 in the left-right direction (width direction) of the main body 1 and are sequentially arranged in that order. Thus, the evaporator 232
Behind the condenser 22 and the blower fan 2 behind the condenser 22
4 and a direction perpendicular to the suction and suction direction in the front-rear direction, that is, in a direction along the left and right side surfaces having a large case area, these components of the refrigeration cycle can be a main body case narrow in the width direction. Can be installed effectively using the internal space, and the suction air and evaporator 2
3. Sufficient contact with the condenser 22 is also possible, so that a sufficient heat exchange area can be secured.

The compressor 21 is disposed at a lower rear portion of the main body 1. Reference numerals 34 and 38 denote gas-liquid separators for preventing the refrigerant from returning to the compressor 21 as a liquid. Reference numeral 26 denotes a dehumidified water storage tank in which dehumidified water is stored. The dehumidified water storage tank 26 is provided at a front portion of a lower portion of the main body so as to be lined with the compressor 21 and has a handle portion 26b formed by being recessed upward at the bottom of the tank 26. , So that it can be pulled out forward. Reference numeral 28 denotes a handle held when the dehumidifier is transported.

Here, as shown in FIGS. 5 and 2, a wind tunnel 29 surrounding the blower fan 24 is provided in the blower passage 20, and a circular suction port formed on one side surface of the wind tunnel 29. 30 faces the condenser 22 and the evaporator 23, and the upper rectangular outlet 31 faces the exhaust port 16. Therefore, due to the presence of the wind tunnel 29, when the blower fan 24 rotates, the room air introduced from the front and rear directions of the main body from the intake ports 5 and 10 is blown by the blower passage 20
2, the flow changes at right angles in the left-right direction (width direction of the main body) of the main body, which is orthogonal to the front-rear direction, as shown by the arrow in FIG. 2, and passes so as to completely hit the evaporator 23 and the condenser 22. After passing through, the air flow changes direction substantially vertically upward, and flows upward in the wind tunnel 29 so as to flow out from the exhaust port 16.

Therefore, the air passage 20 changes the direction in which the room air entering the main body 1 from the intake ports 5 and 10 at the front and rear of the main body flows perpendicularly to the main body 1 in the right and left direction orthogonal to the front and rear direction of the main body 1. In the process of passing through the main body in the width direction, the evaporator 23 and the condenser 22 are brought into full contact with each other to perform efficient dehumidification and drying of the dehumidified air. After the passage, the air passage has a bent structure that allows the air to flow through the exhaust port 16 by changing the direction of the air flowing vertically upward.

With the above-described structure, the refrigeration cycle is operated, and the room air containing much moisture is sucked into the main body in this way and ventilated.
By passing through and coming into contact with, moisture is condensed and dehumidified. Further, the dehumidified air passes through the condenser 22 next, so that the air of the condenser 22 is deprived of heat and exhausted from the exhaust port 16 as high-temperature dry air.

The moisture in the air condensed in the evaporator 23 is removed by a drain pan 3 provided below the evaporator 23.
After dropping to 2, the dehumidified water storage tank 26 (hereinafter abbreviated as a tank) accumulates. And
The tank 26 is provided with a water amount detection switch 33 for detecting that the tank 26 is full. By disposing a buzzer that sounds in conjunction with the water amount detection switch 33 or an illuminated display lamp on the operation unit 18 of the main body upper surface unit 17 or the like, the timing of draining the dehumidified water from the tank is notified. The tank is detachably provided on the lower side in the front-rear direction of the main body having the intake port 5 by pulling out or the like, so that the tank is used with the dehumidifier 1 arranged in the closet 11 as shown in FIG. However, it can be easily pulled out from the near side, and water treatment when the water is full can be easily performed. Further, the mounting after the processing can be performed easily from the front.

Since the dehumidifier of the present invention is configured as described above, for example, when used in the closet 11 as shown in FIG. 1, obstacles such as the inner wall of the closet and the futon are placed on the side of the main body. Even if the air inlets 5 and 10 are in close contact with the dehumidifier main body 1, the air inlets 5 and 10 are located on the front and rear surfaces, but not on the side surfaces, so that the air inlets 5 and 10 are not blocked. Therefore, the amount of ventilation does not decrease, and efficient dehumidification operation can always be performed. In this way, dehumidification in the closet is efficiently performed, and generation of mold and the like is prevented,
Maintain high hygiene and be able to keep clean and safe.

Similarly, although not shown, even if it is placed in a small space such as a place between a wall and furniture at a corner of a room or between furniture and furniture, the air inlets 5 and 10 are opened to the front. Therefore, there is no fear that the intake ports 5 and 10 will be blocked by furniture or the like, and ventilation can be performed efficiently, the room can be sufficiently used, and the room can have a comfortable environment.

Also, when the dehumidified water is to be discarded, the tank 26 may be pulled out as it is, so that the water can be easily discarded. The inconvenience of not being able to take out is eliminated, and the wastewater treatment work is also facilitated.

[0031]

As described above, according to the present invention (claim 1), the air inlet is provided on the front surface of the dehumidifier body having a long and narrow configuration, so that it is installed in the space between the furniture and the furniture. Even so, there is no need to worry that the intake port will be blocked by futons or furniture, and the dehumidifier can be used even in a narrow space, because ventilation is smoothly performed and dehumidification is performed. In addition, the dehumidification water treatment can be performed by easily pulling out the dehumidification water storage tank from the front, and unlike the conventional case, the entire dehumidifier is not once pulled out to remove the tank. Is improved. In addition, even though air is sucked in from the front or back of the elongated body, the evaporator, condenser, blower fan, etc. of the refrigeration cycle that performs dehumidification etc. are moved in the left and right direction of the body orthogonal to the suction direction. By arranging them side by side, it is possible to easily install and install these components even in a limited narrow space inside the main body, and to make good contact between the intake air and the evaporator and condenser. Thus, the effect of securing sufficient heat exchange property can be obtained, and the dehumidifying effect can be sufficiently exhibited.

Further, according to the present invention (claim 2), it is also possible to provide an air inlet at the rear portion of the main body. In this case, the air is taken in from the front and rear, and the air flow rate is sufficient, so that the efficiency is improved. Dehumidification is performed.

According to the present invention (Claim 3), the air passage provided inside the main body is provided so that the air sucked from the front through the intake port is used to move the air in the left-right direction (the main body width) orthogonal to the front-rear direction of the main body. Direction) at right angles to the main body width direction, and after passing through the evaporator, condenser, etc. arranged in the main body width direction, change the direction upward and exhaust the air. Good dehumidification can be expected.

Further, according to the present invention (claim 4), the dehumidifier is provided on a rear surface portion provided with a rear intake port.
Since a projection is provided to secure a space for intake, even if the dehumidifier is pushed too far into the interior such as inside, a gap is maintained between the rear part of the dehumidifier and the back wall, Since the suction port will not be blocked, it is safe to install the dehumidifier roughly.

According to the present invention (claim 5), the suction port is provided so as to be recessed from the outer surface of the main body case.
In the case of the front suction port, for example, even if the closed door closes close to the suction port and ventilation is poor, the suction space will open in the left and right lateral direction, so the suction rate Does not decrease, and a required dehumidifying effect can be obtained. Also, in the case of the rear intake port, even if the intake port is closed from the front, it can be sucked from the lateral direction, so that good ventilation can be maintained as well as the above-mentioned projection, and It becomes possible to dehumidify. Also,
The intake port having a structure that is recessed from the surface of the main body case has an effect of increasing the momentum of the intake air flow, so that the suction performance is improved, the ventilation amount is increased, and an improvement in the dehumidifying ability can be expected.
