DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain recovery device and a drain tank for recovering drain generated in an air conditioner such as a spot cooler or a refrigerator.

[0002]

2. Description of the Related Art FIG. 9 schematically shows an arrangement of main devices housed in a conventional spot cooler. The spot cooler 90 includes a substantially rectangular parallelepiped housing 11 extending from the front surface 14 to the rear surface 13, and the upper half thereof serves as a low-temperature section 20 that cools the evaporator 21 by passing outside air to generate cool air. High temperature section 3 in which half supplies external air to condenser 31 and radiates heat
It is 0. Thus, the spot cooler 90
Low temperature compartment (cold air generating section) inside one housing 11
This is an integrated cooler in which the 20 and the high-temperature section (radiator) 30 are arranged. Further, a plurality of casters 5 are attached to the bottom surface of the housing 11 so that they can be easily moved to an appropriate place. Therefore, it is suitable for partially or short-term cooling of a semi-outdoor factory where it is difficult to cool the interior of the room at once or a container that requires air conditioning only when performing a short-term operation. It is indispensable for summer work.

A conventional spot cooler 90 shown in FIG.
The cooler 90 will be described in further detail below.
A spine fin type heat exchanger 19 is arranged from one side surface 12 a to the rear surface 13 of the housing 11, and an upper portion thereof has a function as an evaporator 21 for cooling outside air and introducing it into the housing, The lower part has a function as a condenser 31 for cooling the compressed refrigerant. In the cooling cycle of the spot cooler 90, a refrigerant such as R22 is used. In the low-temperature section 20 provided with the evaporator 21, outside air passes through the evaporator 21 to become cool air, and is pressurized by the evaporator fan 22 to be discharged from the outlet 7. Be blown out. The refrigerant evaporated by the evaporator 21 is compressed by the compressor 18 installed inside the housing 11 and
Sent to In the high-temperature section 30 provided with the condenser 31, the refrigerant in the condenser 31 is cooled by the sucked outside air, and the outside air whose temperature rises through the condenser 31 is discharged to the outside of the housing 11 by the condenser fan 32 as it is. The cooled refrigerant is expanded through a capillary or an expansion valve and then supplied to the evaporator 21 again, and the above process is repeated.

Further, a drain recovery device 40 is provided at the lowermost layer of the housing 11. In the spot cooler 90, the moisture condensed by the evaporator 21 becomes a drain and drops, and is collected in the drain recovery device 40 through the condenser 31 below the drain cooler. Most of the drain is evaporated by the condenser 31 depending on the state of the outside air. However, the drain that cannot be completely evaporated by the condenser 31 is collected by a drain pan 41 provided below the condenser 31 and is drained by the drain pan 41.
Falls naturally into a drain tank 45 from a drain port 42 provided thereunder and is temporarily stored. The drain tank 45 can be extracted from the rear surface 13, and the occurrence of water leakage can be prevented by discarding the stored drain at an appropriate time.

[0005] The spot cooler 90 houses the above-described equipment, piping and a control device for connecting the equipment to the inside of a housing 11, and a motor 23 for driving a compressor 18 and an evaporator fan 21.
And a motor 33 for driving a condenser fan 33
If only the electric power which is the power source of the power supply is supplied, the cool air can be obtained from the outlet 7 anytime and anywhere. Further, as means for moving the spot cooler 90, the caster 5 is provided on the bottom surface 15b of the housing 11, and the handle 6 is provided on the upper surface 15a of the housing 11, so that the device can be moved to an appropriate place.

[0006]

In such a movable spot cooler, miniaturization and weight reduction are important issues like other electric appliances, and a compact and lightweight spot cooler having a high cooling capacity is demanded. Have been. It is also important that the device can be used with confidence at any time without causing drain leakage or the like.

In a cooling system including an air conditioner such as a spot cooler or a refrigeration system such as a chilled rice bottle, the drain recovery device 40 must be connected to a heat exchanger in order to recover drain generated by an evaporator or the like without using a pump. It is necessary to set it under 19. Accordingly, in order to dispose the heat exchanger 19, it is necessary to secure a height H for installing the drain recovery device 40 below the heat exchanger 19. Therefore, a housing having a height obtained by adding the height of the drain recovery device to the height of the heat exchanger is required. In order to reduce the housing without reducing the heat transfer area, the height of the drain recovery device is limited. There is a need.

The drain pan 45 is omitted with the drain tank 45 omitted.
It is also possible to make the drain collecting device 40 thinner by directly collecting the drain and the housing 11 to be lowered. However, since it is not known where a portable cooling device such as a spot cooler is to be installed, it is necessary to bring the drain pan 41 filled with drain to the drainage place if the user is away from the drainage place. It is not easy to use because the accumulated drain is likely to spill during transportation.

When a drain tank 45 is installed in the drain recovery device 40 so that the drain can be easily discarded, a drain pan 41 is provided.
And the height of the drain tank 45,
A proper clearance C is required between the drain pan 41 and the drain tank 45 so that the drain port 42 extending downward from the drain pan 41 and the upper surface 45a of the drain tank 45 do not come into contact with each other. Therefore, the height H required for installing the drain recovery device 40 is the drain pan 4
The height of the housing 11 is several times the height of the housing 11, and the housing 11 cannot be made small. Although a system in which a drain hole is simply formed in the drain pan 41 in order to reduce the clearance C can drain the drain, the discharged drain is scattered, so the drain is not collected in the drain tank 45 and water leakage occurs. Cause it to do so.

[0010] Such a drain recovery device is not limited to a portable air conditioner such as a spot cooler, but may cause dew condensation in a refrigerator having a heat absorbing unit such as an evaporator, a cold rice bin, or a fixed cooling device. It is a necessary device for cooling equipment with a certain temperature. In particular, for equipment that needs to be installed indoors to collect the drain reliably, an appropriate drain collection device should be installed to drain the drain to the floor, etc. unless the drain collection piping system is in place. It is necessary to prevent leakage. Therefore, the installation space of the drain recovery device is a common issue even in the devices having these cooling functions, and by reducing the installation space of the drain recovery device, the device can be reduced in size and weight, and the manufacturing cost can be reduced. Can also be reduced.

Accordingly, an object of the present invention is to make it possible to realize a very thin drain recovery device having a drain tank. Then, it is an object of the present invention to provide a drain recovery device and a drain tank that can surely collect and discard drain generated in the device, and that can reduce the size of the device, particularly, lower the device.

[0012]

For this reason, in the drain recovery apparatus of the present invention, a drain port which has conventionally been directed downward from the drain pan is provided on the side of the drain pan.
By extending a receiving port above the drain tank so that the drain port can be inserted, the clearance between the drain pan and the drain tank can be minimized. That is, the drain recovery device of the present invention is provided with a drain pan that collects drain containing moisture condensed in a heat absorbing part such as an evaporator and discharges the drain from a drain port protruding laterally, and is disposed so as to be detachable along a bottom surface of the drain pan. And a drain tank which is provided with a drain port extending upward so that a drain port can be inserted into the drain tank.

Thus, instead of the lower side of the drain pan,
By connecting the drain pan and the drain tank on the side, it is not necessary to secure any further clearance including the length of the drain port below the drain pan. On the other hand, since the discharge port can be inserted into the drain tank at the side of the drain pan, the drain is reliably collected in the drain tank without being scattered, and water leakage can be prevented. Therefore, it is possible to provide a thin drain collecting device that can surely collect the drain in the drain tank. For this reason, it has a low-temperature section that can cool and supply air with a heat-absorbing section such as an evaporator, and a high-temperature section that can cool and discharge the heat-dissipating section that radiates the heat absorbed by the heat-absorbing section such as a condenser with outside air. By employing the drain recovery device of the present invention for the cooling device, the space occupied by the drain recovery device can be made extremely thin, so that a small cooling device having a large heat absorbing portion and a large heat radiating portion and high cooling capacity is provided. be able to.

Although it is possible to set up a pipe above the drain tank to extend the receiving port upward, a rising portion extending upward from the end side of the drain tank is provided, and the receiving port is provided on a side surface of the rising portion. It is also possible to form. By arranging the drain tank so that the drain tank can be pulled out from the side of the rising section, the rising section does not become an obstacle, and the drain port and the receiving port can be detached and inserted at the same time as the drain tank is inserted and removed. further,
The rising portion can be formed as a part of a handle provided above the drain tank, so that a drain tank which is easy to insert, pull out and carry, and is excellent in design can be provided.

Further, the drain tank can be formed as a thin, large-capacity drain tank by providing a thin water storage section having upper and lower surfaces formed substantially in a flat plate shape, and one end of the water storage section can be formed. By providing a rising portion extending from the side in a direction perpendicular to the upper surface, the device can be used as a drain tank of the drain recovery device of the present invention. Therefore, it is possible to realize a drain recovery device which is thin overall and has a large drain water storage capacity. Therefore,
By employing this drain recovery device, it is possible to provide a cooling device that is small in size, has a large drainage storage amount, and requires less maintenance.

[0016]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show an outline of a spot cooler 10 as a typical example of a cooling device provided with a drain recovery device according to the present invention. The spot cooler 10 of the present embodiment includes a substantially rectangular parallelepiped housing 11 extending from a front surface 14 to a rear surface 13, and has an upper surface 15 a.
A blowout unit 4 having a blowout opening 4a for cold air is mounted on the front surface 14 side of the blower. In the spot cooler 10 of this embodiment, a handle 6 is provided on an upper surface 15a of a housing 11 so as to be portable.

As shown in FIG. 2, a heat exchanger 19 is arranged along one side surface 12a of the housing 11, and the portion of the heat exchanger 19 serves as an outside air intake. The spot cooler 10 of this example is a spin fin type heat exchanger 19 in which an evaporator 21 and a condenser 31 are vertically integrated.
Therefore, the upper side of the side surface 12a is an intake port 29 for outside air for cool air, and the lower side is an intake port 39 for outside air for heat radiation. Further, an exhaust port 38 for discharging outside air for heat radiation is provided on the rear surface 13 of the housing 11, and a condenser fan for exhaust is provided. In the spot cooler 10 of the present embodiment, a fan cover 37 of the condenser fan is provided so as to protrude slightly outward from the rear surface 13 of the housing 11 so that the entire length of the housing 11 can be shortened. Also, back 1
3 is located below the exhaust port 38 of the third tank.
Is provided.

FIGS. 3 and 4 show a schematic configuration of the inside of the housing 11 of the spot cooler 10 of the present embodiment, focusing on the evaporator 21, the condenser 31, and the drain recovery device 50. The schematic arrangement of the compressor 18, the evaporator fan 22, and the condenser fan 32 is also shown in the figure. In these drawings, only the arrangement of the main components of the spot cooler is taken out and shown. However, it is needless to say that the pipes, valves, cables and the like connecting these components are also housed in the housing 11, It goes without saying that various known systems can be applied to their arrangement and the like. FIG.
A main arrangement inside the housing is shown by using a cross-sectional view of the housing 11 in the front-rear direction, and FIG. 4 shows an interior arrangement when the housing 11 is viewed from the rear. As can be seen from the above, in the spot cooler 10 of this example, the heat exchanger 19 having the evaporator 21 on the upper side and the condenser 31 on the lower side is arranged facing the side surface 12a of the housing 11. The interior of the housing 11 is divided into upper and lower parts, and the upper part is a low-temperature section 20 for cooling the outside air by the evaporator 21 and discharging it from the blowing unit 4 as cool air, and the lower part thereof cools the condenser 31 with the outside air. It is a high-temperature section 30 for radiating heat.

In the spot cooler 10 of this embodiment, a drain recovery device 50 is disposed further below the high-temperature section 30, and a drain tank 55 supports the compressor 18, motors 23 and 33 for a fan, and the heat exchanger 19. It is installed using the space inside the base frame 80. The spot cooler 10 of the present example is a high-temperature section 3
A compressor 18, a motor 23 for an evaporator fan, and a motor 33 for a condenser fan, which are heavy objects, are arranged at 0. These are installed near the center of the base frame 80. As shown in FIG. 5 in an enlarged manner, the base frame 80 has a two-layer structure, the upper part 81 is a structural layer having high strength, and the compressor 18 is installed. Further, an H-shaped support frame 89 extending upward to support the fan motors 23 and 33 is also attached to the structural layer 81. The lower layer of the base frame 80 is the drain tank 5
5 is a tank support layer 82 for installing the tank 5, and a thin space 8 is provided between the structural layer 81 and the tank support layer 82.
3 extends rearward from the front of the housing 11 so that the drain tank 55 can be inserted into the space 83. A heat exchanger 19 is attached to the side 12 a of the base frame 80, and a drain pan 51 extending in the front-rear direction below the heat exchanger 19 is provided on the structural layer 81.

FIGS. 6 and 7 show the drain recovery device 50 of the present embodiment provided with a drain pan 51 and a drain tank 55. FIG. 6 shows an outline of a drain recovery device 50 in which a drain tank 55 is mounted on a drain pan 51, and FIG. 7 shows a configuration of the drain recovery device 50 from a side view using a cross-sectional view. The drain recovery device 50 of the present example includes a tray-shaped drain pan 51 having an open top.
The drain pan 51 is provided along the bottom of the heat exchanger 19 so that the water condensed in the heat exchanger 19 becomes a drain and flows by natural fall. A drain port 53 for discharging the drain flowing into the drain pan 51 is attached to one side wall of the drain pan 51, in this example, a rear wall 52 installed behind the housing 11.
The drain port 53 of this example has a nozzle-like shape protruding from the drain pan 51 toward the rear surface 13. The bottom surface 51a of the drain pan 51 is separated from the front surface 14 to the rear surface 1 at an appropriate angle.
3 so as to become lower toward the drain port 53.
Also, the inner surface 53a of the drain port 53 is formed so that a continuous gradient can be secured from the bottom surface 51a of the drain pan.
1a. Therefore, the drain that has flowed into the drain pan 51 smoothly flows along the gradient of the bottom surface 51a toward the rear wall 52 to the drain port 53,
Further, the water is smoothly discharged from the drain port 53 to a drain tank 55 described later.

The drain tank 55 of this embodiment includes a drain pan 5
1 is arranged along the bottom surface 51a below the bottom surface 51a,
As will be described later, it can be attached to and detached from the drain pan 51 by moving along the bottom surface 51a. FIG.
Alternatively, FIG. 8 shows an outline of the drain tank 55 viewed from a direction different from that in FIG. 7.
An upper surface 56a and a lower surface 56b are flat thin water storage portions 56.
And a handle 57 formed on the end side, in this example, on the rear side.
It has. The handle portion 57 includes two rising portions 57 that rise substantially vertically from both ends on the rear side of the water storage portion 56.
a and 57b, and a grip portion 57c connecting these rising portions 57a and 57b. The drain tank 55 of this example is formed of a resin such as plastic, and has rising portions 57a and 57b and a grip portion 57.
The inside of c is hollow, and is formed in a state of communicating with the water storage section 56. For this reason, a receiving opening 58 is formed on the side surface (front surface) 57d of the one rising portion 57a so that the drain port 53 of the drain pan 51 can be inserted.
The drain flowing from the receiving port 58 is stored in the water storage section 56 and can be held. A discharge port 59 that opens upward is formed on the upper surface 57 e of the other rising portion 57, and is collected in the water storage section 56 by tilting the drain tank 55 with the discharge port 59 side down. Drained drain can be discarded.

A state in which the drain recovery device 50 of the present embodiment provided with such a drain pan 51 and a drain tank 55 is mounted on the spot cooler 10 of the present embodiment will be described. First,
When the drain tank 55 is inserted into the tank space 83 of the base frame 80, the drain port 53 protruding rearward from the drain pan 51 provided on the structural layer 81 becomes the receiving port 58 provided on the side surface of the rising portion 57 a of the drain tank 55. Is inserted into. Therefore, the drain that has flowed into the drain pan 51 flows through the bottom surface 51 a, passes through the drain port 53, passes through the receiving port 58, and is reliably collected in the water reservoir 56 of the drain tank 55. Further, when the drain tank 55 is extracted from the tank space 83, the drain port 53 is removed from the receiving port 58, and the drain tank 5 in a state where the collected drain is accumulated.
5 can be carried separately from the drain recovery device 50 and the spot cooler 10. This drain tank 5
5 is brought to a drain disposal place and the drain tank 55 is tilted with the discharge port 59 down, so that the water storage section 56
The collected drain can be reliably discarded.

The drain recovery device 50 of the present embodiment can reliably recover the drain containing the water condensed in the heat exchanger 19 and the like through the drain pan 51, and collects the drain in the drain tank 55 and appropriately collects the drain. It can be reliably discarded at intervals. Therefore, there is no occurrence of water leakage during the operation of the spot cooler 10, and the drain accumulated in the drain tank 55 can be surely discarded to a predetermined place without spilling on the floor or the like. Further, the drain recovery device 50 of the present example has a drain port 5 on the side (rear side) of the drain pan 51.
3, the drain tank 55 can be detached by pulling the drain tank 55 rearward so that the drain tank 55 can be removed. Therefore, the clearance C between the drain pan 51 and the drain tank 55 is such that the bottom surface 51a of the drain pan 51 and the upper surface 56a of the water storage section 56 of the drain tank 55 move without so much interference and the drain tank 55
Can be made small enough to be removable. Although it is necessary to determine the clearance C in consideration of the frequency of removing the drain tank 55, the drain tank 55
If there is little wear due to the insertion / removal operation, there is no particular problem even if the clearance C is reduced to such an extent that the drain tank 55 and the drain pan 51 are almost in contact with each other. Therefore, the height H required for installing the drain recovery device 50 of the present example can be reduced to about the sum of the height of the drain pan 51 and the height of the drain tank 55, and is very thin with almost no clearance C. The drain recovery device 50 can be installed in the space. Further, regardless of the presence or absence of the clearance C, the length of the drain outlet 53 of the drain projecting to the side can be sufficiently secured, so that the nozzle-shaped drain outlet 53 is surely inserted into the receptacle 58 of the drain tank 55. I can do it. For this reason, by using the drain recovery device 50 of this example, it is possible to provide a drain recovery device that can be installed in a thin space and can reliably recover drain.

In the spot cooler 10 of the present embodiment,
Since the lower space of the base frame 80 is used as the tank space 83, a clearance C between the drain pan 51 and the drain tank 55 is required to sandwich the structural layer 81 made of an iron plate. Can be much smaller than the clearance required to avoid interference with a conventional drain nozzle that projects downward from the drain pan. Further, the base frame 80
By using the space 83 below the structural layer 81 as a space for installing a drain tank, the compressor 1
A large tank space that spreads over the entire bottom surface of the spot cooler 10 without overlapping with the arrangement such as 8 can be secured. For such a tank space 83, by employing the drain tank 55 having the thin water storage portion 56 in which the upper surface 56a and the lower surface 56b of the present embodiment are spread in a flat plate shape, a drain tank having a sufficient capacity even though it is thin. 5
5 can be installed, and as a result, a drain recovery device 50 that is extremely thin as a whole including the height of the drain pan 51 and has a large drain storage capacity can be realized.

By installing a thin (low-height) drain collecting device 50 along the bottom surface of the housing 11, the space above the drain collecting device 50 may generate a drain forming the low-temperature section 20 or the high-temperature section 30. It can be used effectively for the placement of certain equipment. For example, in the spot cooler 10 of the present example, the height of the drain recovery device 50 is reduced, and if the housing is of the same size, a heat exchanger having a large heat transfer area is installed to increase the cooling capacity. A spot cooler 10 can be provided. In addition, if a heat exchanger having the same heat transfer area is arranged on the drain recovery device 50, the housing can be low and small, so that the spot cooler 10 can be reduced in size and weight, and at low cost. Can be manufactured. Furthermore, as in the case of the spot cooler 10 of this example, by changing the arrangement level of the heavy objects such as the compressor 18 and the drain recovery device 50, interference in planar arrangement is eliminated, so that the arrangement of the compressor 18 and the like can be efficiently performed. It is possible to reduce the size of not only the height in the vertical direction but also the size in the front-rear direction or the left-right direction, thereby providing a more compact and high performance spot cooler.

In the drain recovery device 50 employed in the spot cooler 10 of this embodiment, a drain tank 55 having a thin and wide water storage portion 56 can be installed, so that a sufficient amount of drain can be accumulated. Yes, the frequency of maintenance for drain disposal is very small. For example, in the spot cooler 10 described above, continuous operation for about half a day (12 hours) is possible without discarding the drain.

In the above description, a spot cooler has been described as an example. However, other air conditioners having a low-temperature section where water is likely to be condensed due to condensation of water and a high-temperature section for radiating heat, an insulated rice bottle, and other air conditioners are provided. The same applies to a cooling device such as a refrigerator. In the case where the drain is collected in the drain tank and the drain tank can be attached and detached along the bottom of the drain pan, even with these cooling devices, conventionally, interference with the drain nozzle between the drain pan and the drain tank is avoided. That required a lot of clearance. On the other hand, by using the drain recovery device of the present invention, the clearance between the drain pan and the drain tank can be substantially eliminated, and the drain tank can be attached and detached along the bottom surface of the drain pan even in such an arrangement. For this reason, the space for installing the drain recovery device is reduced, and the entire cooling device can be downsized. Further, since the degree of freedom for arranging the heat transfer surface, the compressor, and the like is increased, it is possible to adopt an arrangement having high efficiency in various aspects.

Further, the drain tank 55 employed in the drain recovery device 50 of the present embodiment has a receiving port 58 connected to a drain port 53 extending laterally from the drain pan 51 by using a rising portion 57a constituting a handle portion 57. Is formed.
Therefore, as compared with the case where only the receiving port is extended to the upper surface of the drain tank using a pipe or the like, the strength of the receiving port 58 can be increased because the rising portion 57a is large in size. If the drain port 53 does not enter the receptacle 58, the side face 57d of the rising portion and the drain port 53 interfere with each other, and the drain tank 55 does not fit in the tank space 83. Therefore, it is determined whether or not the drain port 53 fits in the receptacle 58. Confirmation is easy. Therefore, it is possible to reliably prevent the occurrence of water leakage and the like.
Further, since the receiving port 58 is configured as a part of the handle portion 57, it is possible to provide a simple and easy-to-carry drain tank which is excellent in design.

The handle portion 57 of the drain tank of this embodiment is connected only above the rising portions 57a and 57b at both ends by a holding portion 57c, and as shown in FIG. Is formed. Therefore, the drain tank 55 is disposed in the tank space 8 of the base frame 80.
3 can be easily inserted into the space 60 from behind by inserting a hand into the space 60.
5 can be pulled out. In addition, the grip 57c is thin enough to be gripped by hand, so that it is easy to carry. Furthermore, since the receiving port 58 and the discharge port 59 are provided in the handle 57 on the upper side when the drain tank 55 is carried, the drain does not leak when the drain tank 55 is carried. As described above, the drain tank 55 of this example is a tank excellent in design in which the handle portion 57 is integrally formed with the water storage portion 56, and is easily drawn out from the drain recovery device 50 and is easily carried. It is a drain tank with excellent functions.

[0029]

As described above, the drain recovery device of the present invention comprises a drain pan having a drain port protruding to the side and a drain tank having a receptacle port extending upward so that the drain port can be inserted. The drain tank can be drawn out along the bottom surface of the drain pan without providing a clearance between the drain pan and the drain tank arranged vertically. Therefore, it is possible to provide a drain recovery device that can be installed in a very thin space and that does not leak drain. For this reason, by employing the drain recovery device of the present invention, it is possible to reduce the size of an air conditioner such as a spot cooler and other cooling devices, and it is possible to reliably prevent water leakage and the like.

Further, the drain recovery device of the present invention can employ a drain tank having a rising portion for forming a handle extending upward from an end side, and a receiving port is opened on a side surface of the rising portion. The drain outlet of the drain pan can be inserted. In this way, by providing a receiving port in a part of the handle, a very simple drain tank can be provided, and since the drain does not leak from the receiving port when the handle is held, a drain tank that is easy to carry is provided. Can be provided.
