Disclosure of Invention
Technical problem to be solved by the invention
However, the dehumidifying apparatus described in patent document 1 is configured such that the air flowing through the first air flow path does not pass through the heat absorber (cooling unit) or the heat radiator (heat radiating unit). Therefore, the radiator is not cooled by the wind flowing through the first blowing path. As a result, when the cooling of the radiator is insufficient only by the air flowing through the second air flow path, the cooling efficiency of the heat absorber by the refrigeration cycle may be reduced.
If the cooling efficiency of the heat absorber by the refrigeration cycle decreases, the cooling capacity of the air by the heat absorber decreases. As a result, the heat absorber cannot sufficiently condense the water vapor in the air, and the dehumidification capability of the dehumidification device may be reduced.
The invention aims to provide a dehumidifier capable of inhibiting the reduction of dehumidification capacity.
Means for solving the problems
According to a first aspect of the present invention, a dehumidifier comprises: a heating section; a moisture absorption part; a moisture dissipating section; a first cooling section; a second cooling section; a first heat sink portion; a second heat sink member. The moisture absorption portion dehumidifies air. The moisture dispersing section supplies heat from the heating section, and thereby sends out air having a higher humidity than the air sent out from the moisture absorbing section. The first cooling unit and the second cooling unit cool the air. The first heat dissipation portion cools the first cooling portion. The second heat dissipation portion cools the second cooling portion. The moisture absorbing portion, the first cooling portion, and the first heat dissipating portion are arranged in this order. The heating unit, the moisture dispersing unit, the second cooling unit, and the second heat radiating unit are arranged in this order.
Effects of the invention
According to the dehumidifier of the invention, the reduction of the dehumidification capability of the dehumidifier can be inhibited.

Detailed Description
Embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding portions are denoted by the same reference numerals, and description thereof will not be repeated.
[ first embodiment ]
A dehumidifier 100 according to a first embodiment of the present invention will be described with reference to fig. 1 and 2. Fig. 1 is a perspective view of a dehumidifier 100 according to a first embodiment of the present invention, as viewed from the front. Fig. 2 is a perspective view of the dehumidifier 100 according to the first embodiment of the present invention as viewed from the rear.
As shown in fig. 1 and 2, the dehumidifier 100 includes a case 1, a lid member 2a, a drain tank 4, and an operation unit 5.
The housing 1 is a hollow member. The casing 1 has a discharge port 2 and a suction port 3.
The outlet 2 is formed in the front surface of the casing 1. The outlet 2 communicates the inside and the outside of the casing 1. The air outlet 2 sends out the air inside the casing 1 to the outside of the casing 1. The outlet 2 may be formed in the casing 1, or may be located at a position other than the front surface of the casing 1.
The cover member 2a is a substantially plate-shaped member. In fig. 1, a cover member 2a covers the air outlet 2. The cover member 2a is rotatably mounted to the housing 1. The cover member 2a changes the rotation angle, and thereby functions as a louver that defines the direction of the flow of the air sent out from the air outlet 2 to a direction corresponding to the rotation angle of the cover member 2 a.
The suction port 3 is formed in the rear surface of the housing 1 (see fig. 2). The suction port 3 communicates the inside and outside of the casing 1. The suction port 3 allows air outside the casing 1 to flow into the casing 1. The suction port 3 may be formed in the casing 1, or may be located at a position other than the rear surface of the casing 1.
The drain tank 4 is detachably housed in the case 1. The drain tank 4 stores water generated by the dehumidifier 100.
The operation unit 5 is provided at an upper portion of the housing 1. The operation unit 5 receives an instruction from the outside.
Next, referring to fig. 3, the dehumidifier 100 will be further described. Fig. 3 is a schematic view showing the inside of the housing 1.
In fig. 3, the up-down direction is a direction parallel to the vertical direction. The front-rear direction is a direction parallel to the horizontal direction. The dehumidifier 100 is used in a state of being set in a posture as shown in fig. 3.
As shown in fig. 3, the dehumidifier 100 further includes a heater 6, a dehumidifying rotor 7, a cooling unit 8, a heat radiating unit 9, a water collecting unit 10, an air blowing unit 11, a compression unit 12, and an expansion unit (not shown).
Heater 6, dehumidifying rotor 7, cooling unit 8, heat radiating unit 9, air blowing unit 11, and compression unit 12 are disposed inside casing 1.
The heater 6 generates heat to thereby heat the air. The heater 6 is an example of the heating portion of the present invention. The heater 6 faces the suction port 3. The heater 6 is disposed in front of the suction port 3.
The desiccant rotor 7 includes zeolite 71, a rotor 72, and a rotary shaft 73. The rotor 72 is a substantially disk-shaped member. A plurality of zeolites 71 are provided in the rotor 72 along the circumferential direction of the rotor 72. The rotor 72 rotates about a rotation shaft 73.
The desiccant rotor 7 includes a moisture absorption portion 7a and a moisture diffusion portion 7b.
The moisture absorption part 7a is an upper portion of the rotor 72. The moisture absorption portion 7a faces the suction port 3. The moisture absorption portion 7a is disposed in front of the suction port 3. The moisture absorption part 7a does not face the heater 6. The heat is not supplied from the heater 6 to the moisture absorbing part 7a. The supply heat means that air heated by the heater 6 flows therethrough.
The moisture diffusion section 7b is a lower portion of the rotor 72. The moisture releasing section 7b is located below the moisture absorbing section 7a. The moisture diffusion section 7b faces the heater 6. The moisture diffusion section 7b is disposed in front of the heater 6. Heat is supplied from the heater 6 to the moisture diffusion section 7b.
The zeolite 71 rotates together with the rotor 72, and thereby alternately repeats a state of being positioned in the moisture absorption part 7a and a state of being positioned in the moisture dissipation part 7b.
The moisture absorption section 7a dehumidifies air. Specifically, the zeolite 71 located in the moisture absorption unit 7a dehumidifies air. As a result, the dehumidified air is sent out from the moisture absorption portion 7a.
The moisture dispersing unit 7b sends out air (high-humidity air) containing moisture dehumidified by the moisture absorbing unit 7a. Specifically, heat is supplied from the heater 6 to the zeolite 71 located in the moisture diffusion section 7b, and moisture dehumidified when the zeolite 71 is located in the moisture absorption section 7a is vaporized by the moisture diffusion section 7b. As a result, high-humidity air is sent out from the humidity releasing portion 7b.
The compression unit 12 pumps the refrigerant. The compression section 12 includes a compressor. The expansion portion decompresses the refrigerant. The expansion portion, for example, includes a capillary tube. Inside the casing 1, a refrigeration cycle is formed. The refrigeration cycle is a cycle in which a circulation path is formed by annularly connecting the compression unit 12, the heat radiation unit 9, the expansion unit, and the cooling unit 8, and the refrigerant is circulated through the circulation path by the compression unit 12. In the refrigeration cycle, the refrigerant is heated to a high temperature and a high pressure by the operation of the compression portion 12. The refrigerant having a high temperature and a high pressure is sent to the heat radiating portion 9. The heat radiating portion 9 cools the refrigerant by radiating heat of the refrigerant to air passing through the heat radiating portion 9. The refrigerant having passed through the heat radiating portion 9 is sent to the expansion portion. The expansion portion is a portion that generates a refrigerant that has been reduced in temperature and pressure by decompressing the refrigerant cooled by the heat radiating portion 9. The refrigerant passing through the expansion portion is sent to the cooling portion 8. The cooling unit 8 is cooled by supplying a refrigerant of a low temperature and a low pressure from the expansion unit. The refrigerant having passed through the cooling unit 8 is sent to the compression unit 12. In the refrigeration cycle, the refrigerant circulates through the compression portion 12, the heat dissipation portion 9, the expansion portion, and the cooling portion 8 in this order, thereby suppressing a temperature increase in the cooling portion 8. In the refrigeration cycle, the refrigerant that has been heated to a high temperature and a high pressure by the compressor 12 is sent to the heat radiating portion 9, and therefore the temperature of the heat radiating portion 9 rises.
The cooling section 8 cools the air. The cooling section 8 includes an evaporator (evaporator). The cooling unit 8 includes a first cooling unit 8a and a second cooling unit 8b. The first cooling portion 8a is disposed in front of the moisture absorption portion 7a. The second cooling section 8b is disposed in front of the moisture radiating section 7b. The second cooling portion 8b is located below the first cooling portion 8a.
The cooling portion 8 cools the air, thereby condensing water vapor in the air. As a result, the air is dehumidified and water is generated.
In the first embodiment, air having high humidity is sent out from the humidity releasing portion 7b. The air sent out from the moisture radiating portion 7b is supplied to the second cooling portion 8b. Therefore, of the first cooling unit 8a and the second cooling unit 8b, the second cooling unit 8b mainly condenses to dehumidify the air.
The heat radiating portion 9 cools the cooling portion 8 by cooling the refrigerant in the refrigeration cycle. The heat dissipation portion 9 includes a capacitor. The heat sink member 9 includes a first heat sink member 9a and a second heat sink member 9b. The first heat sink portion 9a is disposed in front of the first cooling portion 8a. The second heat sink portion 9b is disposed in front of the second cooling portion 8b. The second heat sink member 9b is located below the first heat sink member 9a.
The water collecting unit 10 collects water generated in the cooling unit 8. Water collecting unit 10 is disposed below cooling unit 8. The water generated in the cooling unit 8 is dropped into the water collecting unit 10.
The water collecting portion 10 is formed in a funnel shape, for example, and guides the supplied water to the drain tank 4. As a result, water is stored in the drain tank 4.
The blowing section 11 blows air. The air blowing unit 11 includes a fan. The blowing unit 11 is disposed in front of the heat dissipation unit 9.
The blower 11 generates a first air path F1 and a second air path F2. The first wind path F1 and the second wind path F2 are formed inside the casing 1. The air having flowed into the casing 1 through the intake port 3 flows through the first air path F1 or the second air path F2, and is then discharged from the air outlet 2 to the outside of the casing 1.
The first air path F1 is formed across the moisture absorption portion 7a, the first cooling portion 8a, and the first heat dissipation portion 9a. In the first air path F1, air flows through the moisture absorption portion 7a, the first cooling portion 8a, and the first heat dissipation portion 9a in this order.
The second air path F2 is formed across the heater 6, the humidity radiating portion 7b, the second cooling portion 8b, and the second heat radiating portion 9b. In the second air path F2, air flows through the heater 6, the humidity radiating portion 7b, the second cooling portion 8b, and the second heat radiating portion 9b in this order.
The dehumidifier 100 further includes a storage unit 13 and a control unit 14.
The storage unit 13 includes a main storage device (e.g., a semiconductor memory) such as a rom (read Only memory) and a ram (random Access memory), and may further include a supplementary storage device (e.g., a hard disk). The main storage device and/or the auxiliary storage device store various computer programs executed by the control unit 14.
The control unit 14 includes a processor such as a cpu (central Processing unit) and an mpu (micro Processing unit). The control unit 14 controls each element of the dehumidifier 100.
Next, the operation of the dehumidifier 100 will be described with reference to fig. 3 to 5. Fig. 4 is a diagram illustrating the flow of air passing through the first wind path F1.
As shown in fig. 3 and 4, after the air outside the casing 1 flows into the casing 1 through the intake port 3, the air flows through the moisture absorption portion 7a, the first cooling portion 8a, and the first heat dissipation portion 9a in this order, and is discharged to the outside of the casing 1 from the outlet port 2.
Fig. 4 shows the first air a1, the second air a2, and the third air A3. The first air a1 is air that flows through the first air path F1 immediately before the moisture absorption portion 7a. The second air a2 is air located between the moisture absorption part 7a and the first cooling part 8a, among the air flowing through the first air path F1. The third air a3 is air located between the first cooling portion 8a and the first heat radiating portion 9a, among the air flowing through the first air path F1.
The humidity of the second air a2 is lower than that of the first air a1 (humidity of the second air a2 < humidity of the first air a 1). The reason is that the first air a1 is dehumidified by the moisture absorption portion 7a when flowing into the moisture absorption portion 7a.
The temperature of the third air A3 is lower than that of the second air a2 (the temperature of the third air A3 < the temperature of the second air a 2). This is because the second air a2 is cooled by the first cooling unit 8a when flowing into the first cooling unit 8a.
The second air a2 becomes the third air A3 cooled by the first cooling portion 8a, and is then supplied to the first heat radiating portion 9a. Therefore, the heat dissipation unit 9 can be cooled by the third air a3, and thus the temperature rise of the heat dissipation unit 9 can be suppressed. As a result, in the refrigeration cycle, the refrigerant can be efficiently cooled by the heat radiating portion 9, and therefore, the cooling efficiency of the cooling portion 8 by the refrigeration cycle can be improved.
Further, the cooling efficiency of the cooling unit 8 in the refrigeration cycle is improved, whereby the cooling state of the cooling unit 8 can be effectively ensured. If the cooling state of the cooling unit 8 is ensured, the cooling capacity of the air by the cooling unit 8 can be improved. Therefore, the cooling unit 8 can efficiently condense the water vapor in the air to generate more water. As a result, the decrease in the dehumidification capability of the dehumidifier 100 can be suppressed.
Fig. 5 is a diagram illustrating the flow of air passing through the second wind path F2.
Fig. 5 shows fourth air a4 and fifth air a 5. The fourth air a4 is air located between the moisture diffusion unit 7b and the second cooling unit 8b, among the air flowing through the second air path F2. The fifth air a5 is air located between the second cooling portion 8b and the second heat radiating portion 9b, among the air flowing through the second air path F2.
As shown in fig. 3 to 5, the temperature of the fourth air a4 is higher than the temperature of the second air a2 (the temperature of the fourth air a4 > the temperature of the second air a 2). The reason is that the second air a2 is not heated by the heater 6 as compared to the fourth air a4 heated by the heater 6.
The humidity of the fourth air a4 is higher than that of the second air a2 (humidity of the fourth air a4 > humidity of the second air a 2). The reason is because the fourth air contains steam generated by the heat of the heater 6 in the moisture radiating section 7b.
The temperature of the fifth air a5 is lower than that of the fourth air a4 (the temperature of the fifth air a5 < the temperature of the fourth air a 4). This is because the fifth air a5 is cooled by the second cooling unit 8b when flowing into the second cooling unit 8b.
When the fifth air a5 is supplied to the second heat sink member 9b, the heat sink member 9 is cooled by the fifth air a 5.
As described above with reference to fig. 3 to 5, the moisture absorbing portion 7a, the first cooling portion 8a, and the first heat radiating portion 9a are arranged in this order of the moisture absorbing portion 7a, the first cooling portion 8a, and the first heat radiating portion 9a. The heater 6, the moisture diffusion portion 7b, the second cooling portion 8b, and the second heat dissipation portion 9b are arranged in this order from the heater 6, the moisture diffusion portion 7b, the second cooling portion 8b, and the second heat dissipation portion 9b. Therefore, the heat dissipation portion 9 (the first heat dissipation portion 9a and the second heat dissipation portion 9b) can be cooled not only by the fifth air a5 flowing from the second cooling portion 8b to the second heat dissipation portion 9b but also by the third air A3 flowing from the first cooling portion 8a to the first heat dissipation portion 9a. As a result, the refrigerant can be efficiently cooled by the heat radiating portion 9 in the refrigeration cycle, and therefore, the cooling efficiency of the cooling portion 8 in the refrigeration cycle can be improved.
In addition, when the temperature of the gas in the dehumidifier 100 is sufficiently high, even when the heater 6 is in the OFF state, the air can be cooled to a degree that condensation is generated in the cooling unit 8. In this case, from the viewpoint of power saving, the dehumidifier 100 may be operated in a state where the heater 6 is OFF. In this case, the heat radiating portion 9 can be cooled by the third air A3 as well as the fifth air a5, and therefore, the cooling efficiency of the cooling portion 8 by the refrigeration cycle can be improved. As a result, the decrease in the dehumidification capability of the dehumidifier 100 can be suppressed.
[ second embodiment ]
A dehumidifier 100 according to a second embodiment of the present invention will be described with reference to fig. 6 and 7. Fig. 6 is a view of second air path F2 as viewed from suction port 3 side. Fig. 7 is a sectional view VII-VII of fig. 6.
In the second embodiment, the point at which the air B sent out from the moisture radiating portion 7B is supplied to the first cooling portion 8a as well as the second cooling portion 8B is different from that in the first embodiment. The following description mainly deals with differences from the first embodiment.
As shown in fig. 6 and 7, the dehumidifier 100 further includes a guide 15.
The guide portion 15 guides the air B sent out from the moisture radiating portion 7B to the first cooling portion 8a and the second cooling portion 8B.
The air B sent out from the moisture dispersing unit 7B is air having a higher humidity than the air sent out from the moisture absorbing unit 7a, and is air to be dehumidified.
The guide portion 15 is disposed between the desiccant rotor 7 and the cooling portion 8. The guide portion 15 includes a first member 151, a plurality of second members 152, and a third member 153.
The first member 151 is a substantially cylindrical member having both ends open. A first opening 151a is formed in one end of the first member 151 (see fig. 7). A second opening 151b is formed in the other end of the first member 151 (see fig. 7). The first opening 151a and the second opening 151b communicate the inside and the outside of the first member 151.
The first opening 151a faces the moisture diffusion unit 7b.
The second member 152 is a generally tubular member. The second member 152 extends in the up-down direction. The second member 152 has a third opening 152a, a plurality of fourth openings 152b, and a plurality of fifth openings 152c (see fig. 7). The third opening 152a, the fourth openings 152b, and the fifth openings 152c communicate the inside and the outside of the second member 152.
The third member 153 is coupled to the upper portions of the plurality of second members 152.
The third opening 152a communicates with the second opening 151b of the first member 151.
Each of the plurality of fourth opening portions 152b faces the first cooling portion 8a. Each of the plurality of fifth openings 152c faces the second cooling portion 8b.
The air B sent out from the moisture diffusion unit 7B flows into the first member 151 through the first opening 151 a. The air B flowing into the first member 151 flows into the second member 152 through the second opening 151B and the third opening 152 a. A part of the air B flowing into the second member 152 is supplied from the plurality of fourth opening portions 152B to the first cooling portion 8a. The other part of the air B flowing into the second member 152 is supplied to the second cooling portion 8B from the plurality of fifth opening portions 152 c. Therefore, the air B sent out from the moisture radiating portion 7B is supplied to the first cooling portion 8a via the guide portion 15 in addition to the second cooling portion 8B. As a result, the air B can be dehumidified using the first cooling unit 8a in addition to the second cooling unit B, and therefore, the air B can be efficiently dehumidified.
The embodiments of the present invention are explained above with reference to the drawings (fig. 1 to 7). However, the present invention is not limited to the above-described embodiments, and can be implemented in various embodiments (for example, (1) to (5)) without departing from the scope of the invention. Further, by appropriately combining a plurality of constituent elements disclosed in the above-described embodiments, various inventions can be formed. For example, some of the components may be deleted from all the components shown in the embodiments. In the drawings, the main components are schematically illustrated for easy understanding, and the number of the illustrated components may be different from the actual number due to the manufacturing of the drawings. The constituent elements shown in the above-described embodiments are examples, but are not particularly limited thereto, and various modifications are possible within a range that does not substantially deviate from the effects of the present invention.
(1) A modification of the dehumidifier 100 according to the first embodiment will be described with reference to fig. 8. Fig. 8 is a schematic view showing a modification of the dehumidifier 100 according to the first embodiment.
In the first embodiment, the heat radiating unit 9 is disposed upstream of the air blowing unit 11. However, the present invention is not limited thereto. As shown in fig. 8, the heat radiating unit 9 may be disposed downstream of the air blowing unit 11. As a result, the same effects as those of the dehumidifier 100 of the first embodiment are obtained. In the dehumidifier 100 according to the second embodiment, the heat radiating unit 9 may be disposed downstream of the blower 11.
(2) In the first and second embodiments, the first cooling unit 8a and the second cooling unit 8b are formed as one member. However, the present invention is not limited thereto. The first cooling unit 8a and the second cooling unit 8b may be formed of separate members.
(3) In the first and second embodiments, the first heat sink member 9a and the second heat sink member 9b are formed of one member. However, the present invention is not limited thereto. The first heat sink member 9a and the second heat sink member 9b may be formed of separate members.
(4) A first example of the control of the dehumidifier 100 by the control unit 14 will be described with reference to fig. 3.
The dehumidifier 100 further includes a temperature measuring unit (not shown) for measuring a room temperature and a humidity measuring unit (not shown) for measuring a humidity in the room. The control unit 14 controls the heater 6 to be ON and OFF based ON the measurement value of the temperature measuring unit and the measurement value of the humidity measuring unit. For example, when the measured value of the temperature measuring unit is equal to or higher than a predetermined temperature and the measured value of the humidity measuring unit is equal to or higher than a predetermined humidity, the control unit 14 turns OFF the heater 6 and operates the dehumidifier 100. ON the other hand, when the measured value of the temperature measuring unit becomes lower than the predetermined temperature or the measured value of the humidity measuring unit becomes lower than the predetermined humidity, the control unit 14 turns ON the heater 6 and operates the dehumidifier 100. As a result, the heater 6 is prevented from being turned ON except for the necessity, so that the operation cost of the dehumidifier 100 can be reduced, and the dehumidifier 100 can be operated efficiently. The predetermined temperature is, for example, 15 ℃. The predetermined humidity is, for example, 60%. The dehumidifier 100 is operated by the blower 11 to generate the first wind path F1 and the second wind path F2.
(5) A second example of the control of the dehumidifier 100 by the control unit 14 will be described with reference to fig. 3.
The control unit 14 functions as a timer. When a first predetermined time elapses after the dehumidifier 100 is operated in a state where the heater 6 is turned ON, the control unit 14 operates the dehumidifier 100 in a state where the heater 6 is turned OFF. In this case, when the laundry is dried using the air discharged from the air outlet 2, first, the air heated by the heat of the heater 6 is blown to the laundry to blow up the moisture contained in the laundry, and then, the unheated air discharged from the air outlet 2 is used to perform the drying process of the laundry in a state where the heater 6 is OFF. As a result, the heater 6 is prevented from being turned ON except when necessary, and therefore, the dehumidifier 100 can be efficiently operated.
When the second predetermined time elapses after the dehumidifier 100 is operated in the state where the heater is turned OFF, the dehumidifier 100 may be operated in the state where the heater 6 is turned ON. As a result, the drying process can be performed so that the laundry after the drying process becomes hot. Each of the first predetermined time and the second predetermined time is, for example, 30 minutes.
[ possibility of Industrial use ]
The invention can be used in the field of dehumidifiers.
