Description

Dehumidifier Field of invention

The present invention relates to a dehumidification apparatus.

Background of the invention

A dehumidifying apparatus that performs cooling and dehumidification by a refrigeration cycle is disclosed in Japanese Laid-Open Patent Publication No. 2005-214533. The configuration of such a conventional dehumidifying apparatus is as follows.

The main body of the dehumidifier is provided with a heat pump device in which a compressor, a radiator, an expansion portion, and a heat absorber are connected in this order by a refrigerant pipe to form a refrigeration cycle. Here, in the heat absorber, the air to be dehumidified is cooled and dehumidified. Further, a heat exchange unit of a positive alternating current type is disposed in the air passage from the heat absorber to the radiator. The sensible heat between the two different wind paths is exchanged in the heat exchange unit.

In the above configuration, the air that has flowed in through the intake port enters one of the air passages, and is pre-cooled by heat exchange with the air cooled and dehumidified by the heat absorber, and then cooled and dehumidified by the heat absorber. Further, the air cooled and dehumidified flows into the other air passage of the heat exchange portion, is heated by the air flowing in from the intake port, and is further heated in the radiator, and is blown from the air outlet to the outside of the body by the air blowing portion.

Summary of invention

In such a conventional dehumidifying apparatus, when the air flowing in from the intake port is pre-cooled in the heat exchange unit, moisture may be condensed into water droplets in the air path and dripped due to the temperature and humidity conditions in the room. Therefore, the treatment of the condensed water in the heat exchange unit is the first problem.

Further, in such a conventional dehumidifying apparatus, in order to reduce power consumption, it is necessary to cool the radiator. However, in order to increase the amount of air supplied to cool the radiator, the air flowing into the heat absorber also increases, so that the amount of sensible heat exchange of the heat absorber is increased, and the air that is sucked is exhausted without being completely dehumidified. Therefore, there is a second problem in which the output of the blower unit is increased.

In order to solve the above first problem, the dehumidifying apparatus of the present invention includes a main body casing, a heat pump device, and a heat exchange unit. The heat pump device is formed by a compressor, a radiator, an expansion portion, and a heat absorber. The first air taken in from the intake port flows through the first heat exchange air passage in the heat exchange unit to become the second air. Then, the second air flows toward the air outlet through the second heat exchange air passage in the heat exchange unit, and the first air exchanges heat with the second air. Further, a blower is provided in the dehumidification air passage from the intake port through the first heat exchange air passage, the heat absorber, the second heat exchange air passage, and the radiator to the air outlet. Further, a water holding portion which is a part of the dehumidification air passage is provided below the heat exchange portion and the heat absorber.

In such a dehumidifying apparatus, even if the humidity in the room is high and the first air is pre-cooled in the heat exchange unit, moisture in the first heat exchange air passage condenses and drops into water droplets, and the water holding portion can hold the condensed water. As a result, the treatment of the condensed water in the heat exchange unit can be surely performed.

Further, in order to solve the above second problem, the main body of the dehumidifier of the present invention and the blower, the heat pump device, and the heat exchanger provided in the main body casing. The body casing has an air inlet and a blow port. The suction port is disposed at a position higher than a center height of the body casing of the body casing. The heat pump device is composed of a compressor, a radiator, an expansion portion, and a heat absorber. The heat sink and the heat absorber face each other, and a heat exchanger is disposed between the heat sink and the heat absorber. The heat exchanger has a first heat exchange air passage and a second heat exchange air passage that exchange heat with each other. Moreover, the upper end of the heat sink is positioned higher than the upper end of the heat exchanger of the heat exchanger.

A portion of the air drawn by the suction port of such a dehumidification device flows through the upper end portion of the heat sink. Therefore, the cooling of the radiator can be performed efficiently without increasing the output of the blower.

Detailed description of the preferred embodiment

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

(Embodiment 1)

Fig. 1 is an external view of a dehumidifying apparatus according to a first embodiment of the present invention, and Fig. 2 is a schematic cross-sectional view of the dehumidifying apparatus of Fig. 1 taken along a plane A and viewed in a B direction. As shown in Fig. 1, the body casing 1 of the dehumidifying device has a box shape. Further, the air suction port 2 is provided on one side of the side surface of the main body casing 1, and the air outlet 3 is provided on the top surface.

As shown in FIG. 2, the dehumidifying apparatus has a heat pump device 30, a heat exchange unit 4, and a blower unit 5 in the main body casing 1. The heat pump device 30 is formed of a compressor 6, a radiator 7, a capillary tube as an expansion portion 8, and a heat absorber 9. Further, the compressor 6, the radiator 7, the capillary, and the heat absorber 9 are connected in this order by the refrigerant pipe 10 to form a refrigeration cycle. The air which is the target of dehumidification in the heat absorber 9 is cooled and dehumidified. The heat sink 7 and the heat absorber 9 are arranged in opposite directions. The heat sink 7 is facing the front in the body casing 1.

Fig. 3 is a schematic view showing the configuration of a heat exchange unit of the dehumidifying apparatus according to the first embodiment of the present invention. The heat exchange unit 4 is formed by laminating a heat transfer plate A11 and a heat transfer plate B12 of a plurality of heat transfer plates. The respective heat transfer plates A11 and B12 are provided with ribs 13, and may constitute an air path when laminated. Next, the first heat exchange air passage 14 that flows in the vertical direction and the second heat exchange air passage 15 that flows in the horizontal direction are formed, and the heat transfer plate A11 is transmitted between the air passages. Heat exchange is performed with the heat transfer plate B12.

The heat exchange unit 4 is a cube in a state in which the heat transfer plate A11 and the heat transfer plate B12 are laminated. As shown in FIG. 2, the heat exchange unit 4 is disposed between the heat sink 7 and the heat absorber 9.

The blower unit 5 shown in FIG. 2 is formed by a scroll-shaped casing portion 16, a motor portion 17 fixed to the casing portion 16, and a blade portion 18 that is rotated by the motor portion 17. The casing portion 16 has a suction port 19 and a discharge port 20. The suction port 19 is opposed to the radiator 7. That is, the heat absorber 9, the heat exchange unit 4, the radiator 7, and the suction port 19 are arranged on a straight line. Further, a part of the lower portion of the heat absorber 9 protrudes downward from the bottom portion 4a of the heat exchange portion 4.

As shown in FIG. 2, the first air 31 sucked by the intake port 2 indicated by the arrow symbol C flows through the first heat exchange air passage 14 in the heat exchange unit 4 to form the second air. 32. Further, the second air 32 flows toward the air outlet 3 and flows through the second heat exchange air passage 15 in the heat exchange unit 4 . The first air 31 is precooled by heat exchange with the second air 32 that has been cooled and dehumidified by the heat absorber 9. The second air 32 passes through a portion that protrudes downward toward the bottom portion 4a of the heat exchange portion 4 of the heat absorber 9, and then reverses the wind direction, and then passes through the remaining portion of the heat absorber 9 to be cooled and dehumidified.

The second air 32 cooled and dehumidified flows into the second heat exchange air passage 15 of the heat exchange unit 4, is heated by the first air 31 sucked from the intake port 2, and is heated in the radiator 7. The air is blown to the outside of the main body casing 1 by the air blowing portion 5. The air passage that has passed through the first heat exchange air passage 14, the heat absorber 9, the second heat exchange air passage 15, and the radiator 7 to the air outlet 3 by the intake port 2 serves as a dehumidification air passage 33 for performing dehumidification. The blower unit 5 is provided in the dehumidification air passage 33.

As shown in FIG. 2, the dehumidifying apparatus in the first embodiment of the present invention The water discharge unit 21 is provided below the heat exchange unit 4 and the heat absorber 9, and the water holding unit 21 is a condensed water generated in the first heat exchange air passage 14 and the heat absorber 9 of the heat exchange unit 4. 34, and become part of the dehumidification wind path 33.

That is, if the indoor humidity is high, the first air that flows in from the intake port 2 When the heat exchange unit 4 is pre-cooled, water sometimes condenses in the first heat exchange air passage 14 and drops into water droplets. However, since the water containing unit 21 is disposed below the heat exchange unit 4 to hold the condensed water 34, the treatment of the condensed water 34 of the heat exchange unit 4 is surely performed. Further, since the water containing portion 21 also serves as the dehumidifying air passage 33, it is not necessary to separately provide the dehumidifying air passage 33, which is a simple configuration, and is an inexpensive dehumidifying device.

As shown in FIG. 2, the bottom portion 4a of the heat exchange portion 4 is a relative horizontal plane. tilt. Thereby, the water droplets condensed in the first heat exchange air passage 14 of the heat exchange unit 4 do not remain in the bottom portion 4a of the heat exchange unit 4. The water droplets flow in a fixed direction toward the bottom portion 4a, and the water droplets do not block the first heat exchange air passage 14. Therefore, it is possible to suppress a dehumidification device capable of suppressing a decrease in the amount of air due to an increase in the pressure loss of the air passage, thereby suppressing a decrease in the dehumidification capability.

Further, the bottom portion 4a of the heat exchange portion 4 is dehumidified toward the heat absorber 9. The bending angle of the road 33 is gently inclined. In the dehumidification air passage 33, the bending angle of the second air 32 flowing out of the first heat exchange air passage 14 of the heat exchange unit 4 decreases. As a result, the dehumidification device can suppress the decrease in the air volume caused by the increase in the pressure loss accompanying the air passage bending, and can suppress the deterioration of the dehumidification capability.

As shown in FIG. 2, the lower end surface 9a of the heat absorber 9 is disposed in the heat exchange. The bottom 4a of the portion 4 is lower. Therefore, the second air 32 flowing out from the bottom portion 4a of the heat exchange portion 4 passes through the portion of the heat absorber 9 that protrudes from the lower portion of the heat exchange portion 4, and then passes through the heat absorber 9 above the bottom portion 4a.

Thereby, in the dehumidification air passage 33, because of the bottom of the heat exchange portion 4 The inclined and vacant space of 4a is provided with a part of the heat absorber 9. Therefore, the effective use of space is achieved.

As shown in FIG. 2, below the water holding portion 21 in the main body casing 1. A tank 22 for storing condensed water 34 is provided. The water containing portion 21 has a partition portion 23 for partitioning the upstream side 9b and the downstream side 9c of the heat absorber 9 of the dehumidifying air passage 33. Further, the drain hole 24 that leads the condensed water 34 from the water containing portion 21 to the groove 22 is disposed on the upstream side 9b of the heat absorber 9.

The second air that flows out of the heat exchange unit 4 by providing the partition portion 23 32 can be surely introduced into the heat absorber 9 to be surely cooled, ensuring dehumidification capability.

Figure 4 is a view showing the dehumidification apparatus of the first embodiment of the present invention. Schematic diagram of the state of the air pressure in the wet wind road. As shown in Fig. 4, in the dehumidification air passage 33 of Fig. 2, the first air 31 which flows in from the intake port 2 by the atmospheric pressure of the external air is subjected to the wind resistance of each component, and expands the pressure difference with the atmosphere, and finally inhales. To the air supply unit 5. When the pressure difference with the atmosphere is larger, the leakage of air increases as the opening that communicates with the atmosphere opens.

The water holding portion 21 shown in Fig. 2 must be set to export the stored water droplets. To the drain hole 24 of the slot 22. The drain hole 24 serves as an opening that communicates with the atmosphere. Because of the pressure difference from the atmospheric pressure in the opening, the air outside the dehumidification air passage 33 flows in, and the dehumidification performance is lowered.

Therefore, as described above, the drain hole 24 is provided upstream of the heat absorber 9. The side 9b, by this, is not affected by the pressure drop caused by the pressure loss of the air passage of the heat absorber 9. As a result, the pressure difference between the second air 32 and the atmospheric pressure which becomes the dehumidification air passage 33 becomes small, and it is possible to suppress the entry of air from the drain hole 24 and to suppress the dehumidification capability from deteriorating.

As described above, according to the dehumidifying apparatus of the first embodiment, the treatment of the condensed water in the heat exchange unit 4 can be surely performed.

(Embodiment 2)

Fig. 5 is a perspective view showing a dehumidifying apparatus according to a second embodiment of the present invention. As shown in FIG. 5, the body casing 101 of the dehumidifying device 110 has a box shape. Further, the main body casing 101 has an intake port 102 and an air outlet 103. The intake port 102 is provided at an upper portion of the outer peripheral wall of the main body casing 101, and the air outlet 103 is provided at the same position as or higher than the intake port 102. When the air outlet 103 is disposed at such a position, the air that has been dehumidified by the dehumidifying device 110 is efficiently blown into the room, and the dehumidification efficiency becomes high.

Fig. 6 is a front elevational view showing the dehumidifying apparatus according to the second embodiment of the present invention. In Fig. 6, the intake port 102 of the dehumidifying device 110 is in an open state. As shown in Fig. 6, from the air inlet 102 in the open state, the upper end 105a of the heat sink 105 located inside the body casing 101 can be seen. When the dehumidifying device 110 is provided, the suction port 102 is disposed at a position higher than the center height 101a of the body casing of the body casing 101. Further, a groove 104 for storing water generated by dehumidification is provided at a lower portion of the dehumidifying device 110.

Furthermore, since FIG. 6 is a front view, the inside of the main body casing 101 is not originally visible. However, for convenience, the display is provided on the body casing 101. The inner tank 104, the compressor 106, the drain pan 107, and the like. The drain pan 107 is disposed below the heat absorber 113 for receiving water dehumidified by the air passing through the heat sink 113, and sends the water to the tank 104.

Fig. 7 is a cross-sectional view taken along line J-J of Fig. 6. As shown in Figure 7, The dehumidifying device 110 has a main body casing 101, a blower 108 provided in the main body casing 101, a heat pump device 130, and a heat exchanger (sensible heat exchanger) 111. Further, in Fig. 7, the display groove 104 is originally shown, but for convenience, the compressor 106 in front is displayed.

The heat pump device 130 is composed of a compressor 106 and a compression device. A radiator (condenser) 105, an expansion portion (capillary) 112, and a heat absorber (evaporator) 113 which are disposed downstream of the refrigerant flow of the machine 106 are connected by a refrigerant pipe to form a refrigeration cycle. In the heat absorber 113, the air to be dehumidified is cooled and dehumidified.

The blower 108 is composed of a scroll portion 108a and a shell fixed to the shell. The motor portion 108b of the body portion 108a is formed by a blade portion 108c that is rotated by the motor portion 108b. The blower 108 blows air from the intake port 102 and blows air from the blower outlet 103. The casing portion 108a has a suction port 109a and a discharge port 109b. The suction port 109a faces the heat absorber 113, the heat exchanger 111, and the radiator 105. That is, the heat absorber 113, the heat exchanger 111, the radiator 105, and the suction port 109a are arranged on a straight line.

Fig. 8 is a top view of the dehumidifying apparatus according to the second embodiment of the present invention. As shown in FIG. 8, the heat sink 105 and the heat absorber 113 face each other, and a heat exchanger 111 is provided between the heat sink 105 and the heat absorber 113.

Figure 9 is a view showing a dehumidifying apparatus according to a second embodiment of the present invention. Diagram of the heat exchanger. As shown in Fig. 9, the heat exchanger 111 is a sensible heat exchanger such as a positive AC type heat exchanger. The heat exchanger 111 is formed by laminating a first heat transfer plate 111a made of resin, metal or the like and a second heat transfer plate 111b.

The heat exchanger 111 has a first heat exchange for heat exchange with each other The air passage 111c and the second heat exchange air passage 111d. In FIG. 9, the first heat exchange air passage 111c is an air passage in the vertical direction, and the second heat exchange air passage 111d is an air passage in the horizontal direction.

As shown by the arrow mark K in Fig. 7, it is sucked by the blower 108. The air taken in by the port 102 flows into the inlet of the first heat exchange air passage 111c on the upper side of the heat exchanger 111 of Fig. 9. The air flowing in to the inlet of the first heat exchange air passage 111c is pre-cooled by heat exchange with the air which has been cooled and dehumidified by the heat absorber 113 of Fig. 7, and is the first one below the heat exchanger 111 of Fig. 9. The outlet of the heat exchange air passage 111c flows out. Next, the air that has flowed out from the outlet of the first heat exchange air passage 111c is cooled and dehumidified by the heat absorber 113 of Fig. 7 .

Cooling the dehumidified air through the heat sink 113 from the second heat exchange of FIG. The inlet of the air passage 111d enters the heat exchanger 111 again, and is heated by the air flowing in from the inlet of the first heat exchange air passage 111c. Next, the air flowing out from the outlet of the second heat exchange air passage 111d is further heated in the radiator 105 of Fig. 7, and is blown to the outside of the main body casing 101 by the blower 108.

Thus, the dehumidification device 110 of FIG. 7 has passed through the suction port 102. The first heat exchange air passage 111c of Fig. 9, the heat absorber 113, the second heat exchange air passage 111d of Fig. 9, and the dehumidification air passage 114 of the radiator 105 to the air outlet 103.

The characteristics of the dehumidification device 110 are as shown by the arrow mark L in FIG. There is a split air path 115. The split air passage 115 passes through the radiator 105 through the intake port 102 to the blow port 103. That is, a portion of the air sucked into the main body casing 101 by the air suction port 102 by the air blower 108 does not pass through the heat exchanger 111 (the first heat exchange air passage 111c and the second heat exchange air passage 111d of Fig. 9). The heat sink 113 passes through the heat sink 105. Thereby, the total amount of air flowing into the radiator 105 is increased as compared with the case where the split air passage 115 is not provided. The upper end portion 105a of the radiator 105 is positioned higher than the heat exchanger upper end 111e of the heat exchanger 111.

In the dehumidifying device 110 of FIG. 7, the diverting air path 115 is used to disperse The air flowing in the heater 105 is increased, and the amount of heat exchange with the air sucked by the refrigerant of the radiator 105 is increased, and the radiator 105 is further cooled.

As shown in Fig. 7, the air taken in by the suction port 102 is divided into The dehumidified air of the wet air passage 114 and the split air passing through the split air passage 115. The amount of air flowing into the heat sink 113 is the amount of air that is most suitable for condensation. In the dehumidifying device 110, the optimum air volume optimum for the heat absorber 113 is secured, and the amount of air to the radiator 105 is increased. Therefore, since the amount of heat radiation in the radiator 105 can be increased, the refrigeration cycle can be efficiently operated to improve the dehumidification capability. Further, the dehumidified air and the split air are blown by the blower 108 by being mixed by the blower 108.

Further, as shown in FIG. 7, the position of the upper end portion 105a may be the height between the upper end 102a of the intake port 102 and the lower end 102b of the intake port. As a result, a portion (split air) sucked from the air inlet 102 provided at the upper portion of the outer peripheral wall of the outer casing 101 enters the heat exchanger 111 in the horizontal direction and reaches the split air passage 115. One part of the upper end Part 105a. The split air passes from the intake port 102 to the upper end portion 105a, and the traveling direction directly reaches the upper end portion 105a with almost no bending. Thus, the ventilation resistance of the split air passage 115 is small.

Further, from the heat exchanger upper end 111e of the heat sink 105 shown in FIG. The length 131 to the upper portion of the upper end portion 105a may also be shorter than the length 132 from the heat exchanger upper end 111e of the heat sink 105 to the lower end portion 105c of the heat sink 105.

The split air passage 115 has a smaller ventilation resistance than the dehumidification air passage 114. Even if the upper length 131 is shorter than the lower length 132, the amount of wind of the split air passage 115 can be ensured. Therefore, the dehumidification of the dehumidification air passage 114 and the cooling of the radiator 105 with the distributing air passage 115 can be performed in a balanced and good manner. As a result, the dehumidification capability can be prevented from being lowered, and the power consumption of the dehumidifying apparatus 110 can be reduced.

Moreover, the amount of split air passing through the split air path 115 can also be compared. The amount of dehumidified air passing through the dehumidification air passage 114 of Fig. 7 is still large. The optimum air volume of the heat absorber 113 can be ensured, and the air volume of the radiator 105 can be increased. Therefore, since the amount of heat radiation of the radiator 105 is increased, the refrigeration cycle can be efficiently operated to improve the dehumidification capability.

Specifically, the upper part of the heat sink 105 of FIG. 7 is connected from the compression. The refrigerant pipe extends from the machine 106, and a refrigerant pipe extending from the expansion portion 112 is connected to the lower portion of the radiator 105. The refrigerant that has become a high temperature in the compressor 106 initially flows into the upper end portion 105a of the radiator 105. Thereby, in the radiator 105, the temperature of the upper portion of the upper end 111e of the heat exchanger is higher than that of the lower portion of the upper end 111e of the heat exchanger. Further, since the dehumidification air passage 114 has the first heat exchange air passage 111c, the heat absorber 113, and the second heat exchange air passage 111d, the split air passage 115 has a smaller ventilation resistance than the dehumidification air passage 114.

As a result, each of the ends 105a flowing through the upper portion of the split air passage 115 The air volume per unit area becomes larger than the air volume per unit area of the radiator 105 flowing through the dehumidification air passage 114.

That is, each of the ends 105a above the temperature of the heat sink 105 is high. The bit area has a larger amount of split air than the amount of dehumidified air. Therefore, the temperature of the heat sink 105 is higher than that of the end portion 105a, and the heat dissipation amount of the heat sink 105 is increased.

As shown in FIG. 7, the heat absorber 113 can also be disposed in the heat exchanger. The upper end 111e has the same height or is lower than the upper end 111e of the heat exchanger. As a result, a part (divided air) sucked from the air inlet 102 provided at the upper portion of the main body casing 101 enters the heat absorber 113 and the heat exchanger 111 to reach the upper end portion 105a. The split air passes from the intake port 102 to the upper end portion 105a, and the traveling direction is not frequently bent, and can directly reach the upper end portion 105a. Thus, the ventilation resistance of the split air passage 115 is small.

Moreover, the suction port 109a, the heat absorber 113, the heat exchanger 111, and The heat sink 105 is opposed.

Moreover, the split air may also be compared to the air supply to the heat pump device 130. The amount of wind on the downstream side of the upper end portion 105a in the direction in which the refrigerant flows is larger than the amount of air blown to the upstream side.

The upper end portion 105a of the heat pump device 130 in the direction in which the refrigerant flows The upstream side is the high temperature portion of the heat sink 105. Therefore, when a large amount of split air is blown to the upstream side of the upper end portion 105a in the direction in which the refrigerant of the heat pump device 130 flows, the heat exchange amount of the radiator 105 becomes large. Therefore, the radiator 105 is efficiently cooled and the power consumption of the heat pump device 130 is reduced.

Specifically, as shown in FIG. 7, the upper end portion 105a is located at a ratio The suction port upper end 102a of the suction port 102 may be close to the position of the suction port lower end 102b. Further, the space portion 116 may be provided between the upper end portion 105a and the main body casing 101. In the main body casing 101, a heat absorber 113, a heat exchanger 111, a radiator 105, and a blower 108 are disposed in this order from the side of the intake port 102. A portion of the space portion 116 is surrounded by the upper end portion 105a and the outer surface of the casing portion 108a. Thereby, the split air easily flows into the vicinity of the upper end portion 105a from the following two faces.

The first of the two faces is the upper end of the heat sink 105 The suction port 102 near 105a faces the surface. The second surface is an upper end portion 105a facing the top of the body casing 101. It is conceivable that the component flows air and flows into the vicinity of the upper end portion 105a from the space portion 116. Further, it is conceivable that a part of the air reaching the space portion 116 hits the outer surface of the casing portion 108a opposed to the intake port 102, whereby the direction is changed downward and flows into the upper end portion 105a.

That is, the air is from the vicinity of the upper end portion 105a and the upper end portion 105a. The surface flows into the upper end portion 105a. Therefore, it is conceivable that the diverted air flows into the vicinity of the upper end portion 105a in comparison with the vicinity of the heat exchanger upper end 111e of the radiator 105.

That is, at the upper end of the direction in which the refrigerant of the heat pump device 130 flows On the upstream side of the portion 105a, a large amount of the divided air flows into the vicinity of the upper end portion 105a. Therefore, the cooling of the upper end portion 105a can be performed in a balanced manner.
