Description

[Technical Field]

[0001] The present invention relates to a dehumidifier. [Background technology]

[0002] Dehumidifiers with excellent condensed water recovery performance have been developed. For example, the dehumidifier disclosed in Patent Document 1 includes a casing, a dehumidification passage, a regeneration passage, a dehumidification rotor, a heat exchanger, and a water storage tank. The dehumidification rotor crosses the dehumidification passage and the regeneration passage. The dehumidification rotor is rotatable. The dehumidification rotor absorbs moisture from air passing through the dehumidification passage. The moisture adsorbed by the dehumidification rotor is released as water vapor into hot air circulating through the regeneration passage. The water vapor is condensed in the heat exchanger and collected in the water storage tank. In the dehumidifier disclosed in Patent Document 1, the heat exchanger is inclined relative to the vertical direction. [Prior art documents] [Patent documents]

[Figure 2] FIG. 2 is a schematic diagram showing the inside of the dehumidifier according to the present embodiment. [Figure 3] FIG. 1 is a schematic diagram showing a heat exchanger according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference characters and description thereof will not be repeated.

[0010] A dehumidifier 100 according to an embodiment of the present invention will be described with reference to Figures 1 and 2. Figure 1 is a perspective view showing the dehumidifier 100. Figure 2 is a schematic view showing the interior of the dehumidifier 100. In this embodiment, the figure shows an X-axis, a Y-axis, and a Z-axis that are perpendicular to each other. The Z-axis is parallel to the vertical upward direction, and the X-axis and Y-axis are parallel to the horizontal direction.

[0011] 1 and 2, the dehumidifier 100 includes a housing 10, a dehumidifying rotor 40, a heat exchanger 30, a water tank 50, and a control unit (not shown). The dehumidifier 100 is, for example, a stationary dehumidifier.

[0012] The housing 10 has a top plate 11 , a bottom plate 12 , a pair of side plates 13 , a front panel 14 , and a rear panel 15 .

[0013] The top plate 11 is disposed opposite the bottom plate 12. The top plate 11 is disposed on the upper side of the housing 10. Specifically, the top plate 11 has an air outlet 11a and an operation panel 11c. The operation panel 11c receives instructions from the outside. The operation panel 11c is disposed in the center of the top plate 11. The air outlet 11a is disposed around the operation panel 11c. The air outlet 11a is an opening having a substantially circular ring shape.

[0014] The front panel 14, the rear panel 15, and the side panels 13 are each disposed between the top panel 11 and the bottom panel 12. The rear panel 15 is disposed opposite the front panel 14. The rear panel 15 is disposed on the positive side of the housing 10 along the Y axis. The side panels 13 have a plurality of air inlets 13a. Each of the plurality of air inlets 13a is an opening. Specifically, each of the plurality of air inlets 13a is disposed at the lower part of the side panels 13.

[0015] The dehumidifying rotor 40 is disposed inside the housing 10. Specifically, the dehumidifying rotor 40 has a filter 41, a frame 42, and a motor 43.

[0016] The frame 42 has an inlet surface 42a, an outlet surface 42b, and a cylindrical portion 42c. The outlet surface 42b is disposed opposite the inlet surface 42a. The outlet surface 42b is disposed above the inlet surface 42a. The inlet surface 42a and the outlet surface 42b are each a mesh body. The cylindrical portion 42c is disposed between the inlet surface 42a and the outlet surface 42b. A ring gear is formed on the outer circumferential surface of the cylindrical portion 42c. Specifically, the ring gear is teeth formed around the entire outer circumferential surface of the cylindrical portion 42c.

[0017] The frame 42 has a rotation axis AX. The motor 43 rotates the frame 42 about the rotation axis AX. The rotation axis AX is inclined with respect to the vertical direction. Specifically, the suction surface 42a and the blowing surface 42b are inclined with respect to the vertical direction. Specifically, the predetermined direction D1 side of the dehumidification rotor 40 is positioned higher than the side of the dehumidification rotor 40 in the opposite direction D2 to the predetermined direction D1. The predetermined direction D1 is the direction from the front panel 14 to the rear panel 15, and extends along the Y axis.

[0018] The filter 41 is disk-shaped. The filter 41 is disposed in a frame 42. The filter 41 releases moisture at a predetermined temperature or higher and adsorbs moisture below the predetermined temperature. The filter 41 is made of, for example, zeolite or silica gel.

[0019] The heat exchanger 30 is disposed above or below the dehumidifying rotor 40. Specifically, the heat exchanger 30 is disposed below the dehumidifying rotor 40. The heat exchanger 30 has a plurality of pipes 31. Air flows through each of the plurality of pipes 31. The plurality of pipes 31 are made of a material such as synthetic resin or metal. The synthetic resin is, for example, polypropylene.

[0020] Each of the multiple pipes 31 extends along a predetermined direction D1 in a plan view. The multiple pipes 31 are arranged horizontally in two or four rows, one above the other. As a result, the heat exchanger 30 is a substantially rectangular parallelepiped, and has an inlet surface 30a and an outlet surface 30b. The outlet surface 30b is disposed opposite the inlet surface 30a. The outlet surface 30b is disposed above the inlet surface 30a. The extension direction of each of the multiple pipes 31 is inclined with respect to the vertical direction. In other words, the inlet surface 30a and the outlet surface 30b are inclined with respect to the vertical direction. Specifically, the side of the heat exchanger 30 in the predetermined direction D1 is disposed at a higher position than the side of the heat exchanger 30 in a direction D2 opposite to the predetermined direction D1.

[0021] Specifically, the distance between the predetermined direction D1 side of the dehumidifying rotor 40 and the predetermined direction D1 side of the heat exchanger 30 is shorter than the distance between the opposite direction D2 side of the dehumidifying rotor 40 to the predetermined direction D1 and the opposite direction D2 side of the heat exchanger 30. More specifically, the distance between the predetermined direction D1 side of the suction surface 40a of the dehumidifying rotor 40 and the predetermined direction D1 side of the blowing surface 30b of the heat exchanger 30 is shorter than the distance between the opposite direction D2 side of the suction surface 40a of the dehumidifying rotor 40 to the predetermined direction D1 and the opposite direction D2 side of the blowing surface 30b of the heat exchanger 30. Furthermore, the inclination angle with respect to the vertical direction is larger for the heat exchanger 30 than for the dehumidifying rotor 40.

[0022] The heat exchanger 30 exchanges heat between the first air flowing from the multiple inlets 13a to the outlet 11a and the second air flowing through the multiple pipes 31. Specifically, the second air transfers heat to the first air, causing the temperature of the second air to decrease. As a result, water droplets based on water vapor in the second air adhere to the multiple pipes 31. Therefore, the water droplets flow along the multiple pipes 31 in the opposite direction D2.

[0023] The water storage tank 50 is disposed within the housing 10. The water storage tank 50 is disposed below the heat exchanger 30. The water storage tank 50 stores water produced by the heat exchanger 30.

[0024] The control unit is disposed inside the housing 10. The control unit is disposed below the heat exchanger 30 on the side facing the predetermined direction D1. The control unit is a hardware circuit including a processor such as a CPU (Central Processing Unit). In detail, the control unit controls the operation panel 11c and the dehumidification rotor 40 by executing a control program.

[0025] Next, the flow of the first air will be described. The dehumidifier 100 further includes a dehumidification passage 61 and a first blower section .

[0026] The dehumidifying passage 61 is disposed between the plurality of inlets 13a and the outlet 11a. The dehumidifying passage 61 crosses the dehumidifying rotor 40 and the heat exchanger 30 on the predetermined direction D1 side in the vertical direction.

[0027] The first blower 70 is disposed in the dehumidification passage 61. The first blower 70 includes, for example, a fan 70a and a motor 70b. The motor 70b rotates the fan 70a. The fan 70a generates a first airflow. The first airflow passes through the multiple intake ports 13a, the predetermined direction D1 side of the heat exchanger 30, the predetermined direction D1 side of the dehumidification rotor 40, and the air outlet 11a, in this order. As a result, the first airflow is dehumidified by the dehumidification rotor 40 as it passes through the dehumidification rotor 40. Thus, the dehumidified first air is released from the dehumidifier 100. Note that the surface of the dehumidification rotor 40 through which the first airflow generated by the first blower 70 passes is inclined with respect to the vertical direction.

[0028] Next, the flow of the second air will be described. The dehumidifier 100 further includes a regeneration passage 62, a second blower section 90, and a heater 95.

[0029] The regeneration passage 62 is connected to the heat exchanger 30. The regeneration passage 62 crosses the dehumidification rotor 40 and the heat exchanger 30 in the vertical direction on the side of the dehumidification rotor 40 and the heat exchanger 30 in the direction D2 opposite to the predetermined direction D1.

[0030] The second blower 90 and the heater 95 are disposed in the regeneration passage 62. The second blower 90 includes, for example, a fan 90a and a motor 90b. The motor 90b rotates the fan 90a. The fan 90a generates a second airflow. The second airflow circulates through the heater 95, the side of the dehumidifying rotor 40 opposite the predetermined direction D1 in the opposite direction D2 to the predetermined direction D1, and the side of the heat exchanger 30 opposite the predetermined direction D1 in this order. As a result, the second airflow is heated when it passes through the heater 95. Furthermore, as the second airflow passes through the dehumidifying rotor 40, the dehumidifying rotor 40 releases water into the second air. The heat exchanger 30 exchanges heat between the first air and the second air. As a result, water droplets based on water vapor in the second air adhere to the multiple pipes 31. Since the heat exchanger 30 is inclined relative to the vertical direction, the water droplets flow along the multiple pipes 31 in the opposite direction D2.

[0031] As described above with reference to FIGS. 1 and 2 , in the dehumidifier 100, the dehumidifying rotor 40 is inclined relative to the vertical direction, and the heat exchanger 30 is also inclined relative to the vertical direction. As a result, it is not necessary to align the dehumidifying rotor 40, the heat exchanger 30, the heater 95, and the control unit in the vertical direction. This allows the height of the dehumidifier 100 to be reduced. Furthermore, because the flow of the first air is vertical, by slanting the dehumidifying rotor 40, the dehumidifying rotor 40 is inclined relative to the flow of the first air, reducing the amount of first air that passes through without being absorbed, thereby improving the moisture absorption amount. Furthermore, if a small foreign object falls on the dehumidifying rotor 40, it would continue to rotate while remaining on the dehumidifying rotor 40 if it were horizontal. However, by slanting the dehumidifying rotor 40, the foreign object can be dropped off of the dehumidifying rotor 40.

[0032] Furthermore, the predetermined direction D1 side of the dehumidifying rotor 40 is disposed at a higher position than the opposite direction D2 side of the dehumidifying rotor 40 from the predetermined direction D1, and the predetermined direction D1 side of the heat exchanger 30 is disposed at a higher position than the opposite direction D2 side of the heat exchanger 30 from the predetermined direction D1. As a result, the heater 95 and the control unit can be disposed in different directions relative to the dehumidifying rotor 40 and the heat exchanger 30. Therefore, the dehumidifier 100 can be made smaller.

[0033] Furthermore, the distance between the predetermined direction D1 side of the dehumidifying rotor 40 and the predetermined direction D1 side of the heat exchanger 30 is shorter than the distance between the opposite direction D2 side of the dehumidifying rotor 40 from the predetermined direction D1 and the opposite direction D2 side of the heat exchanger 30. As a result, the heater 95 can be disposed on the opposite direction D2 side of the dehumidifying rotor 40 from the predetermined direction D1, and the control unit can be disposed on the predetermined direction D1 side of the heat exchanger 30. Therefore, the dehumidifier 100 can be made smaller.

[0034] The dehumidifier 100 includes a dehumidification passage 61 and a regeneration passage 62. Compared to a dehumidifier without the regeneration passage 62, the dehumidifier 100 can dehumidify for a longer period of time.

[0035] Next, the heat exchanger 30 will be described in detail with reference to Fig. 3. Fig. 3 is a schematic diagram showing the heat exchanger 30.

[0036] As shown in FIG. 3, the multiple pipes 31 include M first pipes 31a and N second pipes 31b. In the M first pipes 31a, the second air flows in a predetermined direction D1 of the heat exchanger 30. In the N second pipes 31b, the second air flows in a direction D2 opposite to the predetermined direction D1. M is greater than N. As a result, the second air flows in the direction opposite to the direction in which the condensation water drips, and by ensuring the area of ​​the first pipes 31a, clogging of the multiple pipes 31 can be prevented.
