For example, Patent Document 1 includes: a main body housing having an inlet and an outlet; a dehumidification section disposed within the main body housing for dehumidifying air; and an air supply section for supplying air drawn in from the inlet through a portion of the dehumidification section to the outlet. The dehumidification section includes a heat absorber, a heat exchanger, and a radiator. The heat exchanger includes a plurality of first passages extending in the transverse direction and a plurality of second passages extending in the longitudinal direction and independent of the first passages.

[0005] Patent Document 1: Japanese Patent Application Publication No. 2020-116580 Summary of the Invention

[0006] Within the main casing, the blower is positioned closer to the radiator than the absorber. Therefore, among the multiple second passages extending longitudinally, the airflow in the passage closer to the radiator is greater than that in the passage closer to the absorber. Consequently, when the air flowing in the second passages is not sufficiently cooled, condensation becomes inadequate, making it difficult to improve dehumidification capacity.

[0007] The purpose of this invention is to provide a technology to improve dehumidification capabilities.

[0008] One aspect of the dehumidification device of the present invention includes: a main body housing having an air inlet and an air outlet; an absorber, a heat exchanger, a radiator, and a blower arranged sequentially in the front-rear direction of the main body housing; a first dehumidification path, which utilizes the action of the blower to allow a first portion of the intake air drawn into the main body housing from the air inlet to pass sequentially through the absorber, a first passage of the heat exchanger, and the radiator and be blown out of the main body housing from the air outlet; and a second dehumidification path, which allows a second portion of the intake air to pass sequentially through a second passage of the heat exchanger and the radiator and be blown out of the main body housing from the air outlet, the second passage including an absorber-side passage extending from the upper side to the lower side on the absorber side and a radiator-side passage extending from the upper side to the lower side on the radiator side, and an opening area adjustment section is further included above the inlet opening of the radiator-side passage to suppress the inflow of the second portion of the intake air into the radiator-side passage.

[0009] According to the present invention, the dehumidification capacity can be improved. Attached Figure Description

[0021] Hereinafter, embodiments for carrying out the present invention will be described with reference to the accompanying drawings. The embodiments described below represent preferred examples of the present invention. Therefore, the numerical values, shapes, materials, constituent elements, the arrangement and connection of constituent elements, and the steps (processes) and order of steps shown in the following embodiments are examples and do not limit the scope of the present invention. Therefore, in the constituent elements of the following embodiments, constituent elements not described in the independent claims representing the superior concept of the present invention are described as arbitrary constituent elements. Furthermore, in the figures, substantially identical structures are labeled with the same reference numerals, and repeated descriptions are omitted or simplified.

[0022] In addition, terms including ordinal numbers such as first and second are used to describe multiple constituent elements, but these terms are used only for the purpose of distinguishing one constituent element from other constituent elements, and do not limit the constituent elements by these terms.

[0023] This embodiment is described in the order of (1) the overall structure and (2) the structure of the second passage of the heat exchanger.

[0024] (1) Overall structure

[0025] Reference Figures 1-6 The following describes the general structure of the dehumidification device 100 according to an embodiment of the present invention. Figure 1 This is a perspective view showing the dehumidification device 100 of this embodiment. Figure 2 It is along Figure 1 Cross-sectional view of the dehumidification device 100 of the AA line.

[0026] like Figure 1 As shown, an orthogonal coordinate system comprising the x-axis, y-axis, and z-axis is defined. The x-axis extends in the front-back direction, the y-axis extends in the left-right direction, and the z-axis extends in the up-down direction. The positive direction of the x-axis is called "front" or "front side," and the negative direction of the x-axis is called "back" or "rear side." Similarly, the positive direction of the y-axis is called "right" or "right side," and the negative direction of the y-axis is called "left" or "left side." Furthermore, the positive direction of the z-axis is called "up" or "upside," and the negative direction of the z-axis is called "down" or "downside." Sometimes, the view of the dehumidifier 100 from the front or back is referred to as "front view" or "back view," the view from the left or right is referred to as "side view," and the view from above is referred to as "top view."

[0027] The airflow within the dehumidifier 100 is sometimes referred to as "wind," and the upstream of this airflow is sometimes called "upwind," and the downstream is called "downwind." These designations do not limit the operating posture of the dehumidifier 100, which can be used in any posture.

[0028] like Figure 1As shown, the dehumidifier 100 of this embodiment has a box-shaped main body shell 1 as its outer contour, and the main body shell 1 is used to distinguish the outside and inside of the main body shell 1. The front-to-back width (x-axis direction) of the main body shell 1 is smaller than its left-to-right width (y-axis direction), and the top-to-bottom width (z-axis direction) is larger than its left-to-right width (y-axis direction). The upper surface of the main body shell 1 is the upper part 20, the left side is the first side part 21a, the right side is the second side part 21b, the front surface is the front part 22, and the rear surface is the rear part 23. The first side part 21a and the second side part 21b are opposite to each other, and the front part 22 and the rear part 23 are opposite to each other. The first side part 21a and the second side part 21b are collectively referred to as the side part 21.

[0029] A first air intake 2a (not shown) is provided on the first side portion 21a, and a second air intake 2b is provided on the second side portion 21b. The first air intake 2a and the second air intake 2b are collectively referred to as air intake 2. The air intake 2 is a rectangular opening with a grid pattern that draws in air in a direction perpendicular to the side portion 21 (y-axis direction) relative to the main body housing 1. An air outlet 4 and a louver 31 are provided on the rear side of the upper portion 20. The louver 31 is positioned above the air outlet 4 to change the direction of the air blown out from the air outlet 4. An operation unit 25 is provided on the front side of the upper portion 20. The operation unit 25 is, for example, an interface for receiving input from the user or displaying information related to the dehumidifier, such as the operating mode and current humidity, to the user.

[0030] like Figure 2 As shown, the dehumidification device 100 includes a dehumidification section 5, a blower 6, and a heat exchanger 11. The dehumidification section 5 includes a compressor 7, a radiator 8, an expander 9, and a heat absorber 10. The heat absorber 10, the heat exchanger 11, the radiator 8, and the blower 6 are arranged sequentially in the front-rear direction within the main housing 1. Furthermore, in the front-rear direction, a heat absorber gap 15 is provided between the heat absorber 10 and the front part 22, and a radiator gap 19 is provided between the radiator 8 and the heat exchanger 11.

[0031] The blower 6 includes a motor 32 and a fan 33 connected to the rotating shaft of the motor 32 for drawing in and expelling air. The blower 6 also has an opening, namely an air intake 68, located on the side opposite the radiator 8. The blower 6 draws in air passing through the dehumidification section 5 through the air intake 68 and blows it outwards. Thus, through the action of the blower 6, air drawn in from the air intake 2 outside the main housing 1 passes through the dehumidification section 5 and is blown outwards from the air outlet 4. This series of airflow paths is called the (air intake 2 → dehumidification section 5 → air outlet 4) air passage 34. That is, the air passage 34 connects the air intake 2 and the air outlet 4, and through the action of the blower 6, air drawn into the main housing 1 from the air intake 2 passes through the air passage 34 and is blown out from the air outlet 4.

[0032] Here, to illustrate that air passage 34 also uses Figure 3 , Figure 4 . Figure 3 The air passage 34 of the dehumidifier 100 is schematically shown. According to... Figure 3 The air drawn into the main body housing 1 from the air intake port 2 is called intake air 60. The intake air 60 is divided into a first part 61, a second part 62, a third part 63 and a fourth part 64 within the main body housing 1. Figure 4 The airflow of the dehumidifier 100 is schematically represented by overlaying the flow of the first part 61, the second part 62 and the third part 63 on a cross-sectional view.

[0033] Air passage 34 includes multiple dehumidification paths, namely, a first dehumidification path 51, a second dehumidification path 52, a third dehumidification path 53, and a fourth dehumidification path 54. The airflow path through the first dehumidification path 51 is referred to as the first airflow path 71, the airflow path through the second dehumidification path 52 as the second airflow path 72, the airflow path through the third dehumidification path 53 as the third bypass ventilation path 73, and the airflow path through the fourth dehumidification path 54 as the first bypass ventilation path 74 and the second bypass ventilation path 75. In other words, air passage 34 can also be described as consisting of the first airflow path 71, the second airflow path 72, the third bypass ventilation path 73, the first bypass ventilation path 74, and the second bypass ventilation path 75. The first airflow path 71, the second airflow path 72, the third bypass ventilation path 73, the first bypass ventilation path 74, and the second bypass ventilation path 75 will be described later.

[0034] The dehumidification unit 5 is composed of a refrigeration cycle in which the compressor 7, radiator 8, expander 9, and absorber 10 are connected in a ring. The refrigerant used in the refrigeration cycle is, for example, a Freon substitute (HFC134a). The refrigerant extruded from the compressor 7 flows downwards through the refrigerant piping 80 inside the radiator 8. Therefore, the temperature increases as you go higher in the radiator 8. The refrigerant extruded from the radiator 8 is supplied to the absorber 10 via the expander 9. The refrigerant supplied to the absorber 10 flows upwards inside the absorber 10 and flows back into the compressor 7 through the refrigerant piping 83. The refrigeration cycle is well-known, therefore a detailed description is omitted.

[0035] Inside the main housing 1, a heat absorber 10 is provided on the upstream side of the airflow in the air passage 34, i.e., the air intake 2 side, and a radiator 8 is provided on the downstream side of the airflow in the air passage 34, i.e., the air outlet 4 side. A sensible heat exchanger 11 is arranged in the space between the heat absorber 10 and the radiator 8. In other words, the heat absorber 10, the heat exchanger 11, and the radiator 8 are arranged sequentially from the upstream side to the downstream side of the airflow in the air passage 34.

[0036] like Figure 2 As shown, the heat exchanger 11 has a first passage 17 in the transverse direction (negative X-axis direction) through which a first portion 61 of the intake air 60 passes, and a second passage 18 in the longitudinal direction (negative Z-axis direction) through which a second portion 62 of the intake air 60 passes. The first passage 17 and the second passage 18 are independent airflow spaces. The structure and shape of the heat exchanger 11 are not limited. As an example, the heat exchanger 11 has the first passage 17 and the second passage 18 formed between multiple laminated resin plates (not shown). The heat exchanger 11 is configured to allow heat exchange between the first portion 61 passing through the first passage 17 and the second portion 62 passing through the second passage 18. As an example, the heat exchanger 11 has a cuboid shape.

[0037] The first air path 71 (i.e., the first dehumidification path 51) uses the blower 6 to blow a first portion 61 of the intake air 60 drawn into the main body housing 1 from the air intake 2 through the first passage 17 of the heat absorber 10 and the heat exchanger 11 and the radiator 8 out of the air outlet 4 to the outside of the main body housing 1. Meanwhile, the second air path 72 (i.e., the second dehumidification path 52) uses the blower 6 to blow a second portion 62 of the intake air 60 drawn into the main body housing 1 from the air intake 2 through the second passage 18 of the heat exchanger 11 and the radiator 8 out of the air outlet 4 to the outside of the main body housing 1.

[0038] The first part 61 is first cooled by the absorber 10. At this time, condensation occurs in the first part 61, producing condensate. The condensate drips downwards and is collected by a funnel-shaped water collection section 12a located below the absorber 10 and the heat exchanger 11. The condensate collected by the water collection section 12a flows into a water collection tank 12b located below the water collection section 12a. The water collection tank 12b can be easily installed and removed from the main housing 1.

[0039] Through heat exchange, the cooled first portion 61 flowing in the first passage 17 lowers the temperature of the second portion 62 flowing in the second passage 18. As a result, condensation also forms on the second portion 62 that has not passed through the absorber 10. The condensation drips downward from the second passage 18, is collected by the funnel-shaped collection section 12a, and flows into the collection tank 12b.

[0040] In this embodiment, the heat exchanger 11 sets the ventilation resistance of the second passage 18 to be greater than that of the first passage 17. As a result, the amount of the second portion 62 flowing in the second passage 18 is less than the amount of the first portion 61 flowing in the first passage 17.

[0041] The dried first portion 61, after condensation, is blown out of the main housing 1 through the air outlet 4. Additionally, the dried second portion 62, after condensation, is blown out of the main housing 1 through the heat exchanger 11 via the radiator 8 and the blower 6 through the air outlet 4. By blowing the dried first portion 61 and the second portion 62 out of the main housing 1, the dehumidifier 100 reduces the humidity of the surrounding space.

[0042] Next, the third side ventilation passage 73 will be explained. For example... Figure 4 As shown, the third bypass ventilation path 73 is a bypass ventilation path through which a third portion 63 of the intake air 60 is blown out of the main body housing 1 from the air outlet 4 via a specific portion 88 of the radiator 8, bypassing the absorber 10 and the heat exchanger 11. Furthermore, the specific portion 88 corresponds to the upper portion 8a of the radiator 8, which will be described later. In this embodiment, the specific portion 88 is located on the upper side of the radiator 8 (i.e., the upper portion 8a), but it is not limited to this; it can be positioned anywhere as long as a portion of the intake air 60 can be blown out of the main body housing 1 without passing through the absorber 10 and the heat exchanger 11. In other words, the third bypass ventilation path 73 is a bypass ventilation path through which a portion of the intake air 60, i.e., the third portion 63, flows around the absorber 10 and the heat exchanger 11.

[0043] In this embodiment, the third bypass ventilation path 73 is positioned higher than the first bypass ventilation path 74 and the second bypass ventilation path 75. The third bypass ventilation path 73 blows a third portion 63 of the intake air 60 out of the main housing 1 via the upper part 8a of the radiator 8 through the air outlet 4, bypassing the absorber 10 and heat exchanger 11. In this case, the upper part 8a of the radiator 8 is cooled by the third portion 63, thus increasing the cooling capacity of the radiator 8 and thereby improving the dehumidification capacity of the dehumidification device 100, further reducing power consumption.

[0044] The upper part 8a of the radiator 8 refers to the portion of the radiator 8 that is slightly above the center in the vertical direction. In this embodiment, the radiator 8 protrudes upwards from the upper end of the heat absorber 10 and the upper end of the heat exchanger 11, and this protruding portion is referred to as the upper part 8a.

[0045] The third section 63, having a third bypass ventilation path 73, can cool the upper part 8a of the radiator 8 and, through the refrigeration cycle of the dehumidification section 5, cool the absorber 10, thereby improving the dehumidification capacity of the dehumidification device 100. The refrigerant, which is at a high temperature in the compressor 7, initially flows into the upper part 8a of the radiator 8, thus the temperature of the upper part 8a is higher than that of other parts. Therefore, cooling the upper part 8a through the third section 63 effectively cools the radiator 8. Furthermore, the first section 61 and the second section 62 pass through the portion lower than the upper part 8a of the radiator 8.

[0046] Next, refer to Figure 5 , Figure 6 The first side ventilation passage 74 and the second side ventilation passage 75 are explained. Figure 5 This is a three-dimensional view of the radiator 8 as seen from the left front. Figure 6 This is a view of the back of the radiator 8. The first side ventilation path 74 and the second side ventilation path 75 are air paths that flow around the absorber 10 and the heat exchanger 11 as part of the fourth part 64 of the intake air 60.

[0047] according to Figure 6The radiator 8 has a refrigerant piping 80 consisting of pipes for refrigerant used in the refrigeration cycle. The refrigerant piping 80 includes a plurality of main refrigerant pipes 81a extending laterally, and a first U-shaped pipe 81b and a second U-shaped pipe 81c connecting the plurality of main refrigerant pipes. The first U-shaped pipe 81b is located on one side of the radiator 8, and the second U-shaped pipe 81c is located on the other side of the radiator 8. In the dehumidification device 100, air passages are provided that surround the first U-shaped pipe 81b and the second U-shaped pipe 81c respectively. The air passage surrounding the first U-shaped pipe 81b is referred to as a first bypass ventilation passage 74, and the air passage surrounding the second U-shaped pipe 81c is referred to as a second bypass ventilation passage 75. In this embodiment, an example is shown where both the first bypass ventilation passage 74 and the second bypass ventilation passage 75 are provided, but it is also possible to omit either the first bypass ventilation passage 74 or the second bypass ventilation passage 75.

[0048] The first side ventilation path 74 and the second side ventilation path 75 are described in detail. Here, we will mainly describe the first side ventilation path 74, but this description can also be applied to the second side ventilation path 75. In this case, the first U-shaped pipe 81b is renamed the second U-shaped pipe 81c. For example... Figure 5 , Figure 6 As shown, the radiator 8 has a resin outer frame 84 that supports the refrigerant piping 80. A first side ventilation passage 74 and a second side ventilation passage 75 are provided on the side of the outer frame 84, and a radiator side cylinder portion 85 is provided at the front of the outer frame 84. The radiator side cylinder portion 85 extends forward from the radiator 8 toward the heat exchanger 11. The radiator side cylinder portion 85 surrounds part or all of the heat exchanger 11. The outer frame 84, the first side ventilation passage 74, the second side ventilation passage 75, and the radiator side cylinder portion 85 are integrally formed by resin molding.

[0049] The radiator side section 85 is integrally formed by four plate-shaped protruding parts extending forward from the four edges of the outer frame 84 (top, bottom, left, and right). The radiator side section 85 is composed of an upper protruding part 85a on the upper side, a left protruding part 85b on the left side, a lower protruding part 85c on the lower side, and a right protruding part 85d on the right side. Specifically, as... Figure 5 As shown, the upper protruding part 85a has a plurality of rectangular openings 86 arranged horizontally. The plurality of rectangular openings 86 open upward. The second part 62 can flow downward through the rectangular openings 86.

[0050] The first side ventilation passage 74 is composed of a hollow, square-shaped component extending vertically along the side of the outer frame 84, arranged to surround the first U-shaped tube 81b. The first side ventilation passage 74 has a first opening 74a into which the fourth portion 64 flows. In this embodiment, the first opening 74a is located at the upper part of the first side ventilation passage 74. The first opening 74a is located at least above the vertical center of the first side ventilation passage 74. Preferably, the first opening 74a is located within 30% of the vertical length of the first side ventilation passage 74 when the vertical length is set to 100%. In this embodiment, the first opening 74a is a rectangular opening that opens upwards from the upper end of the first side ventilation passage 74.

[0051] The first side ventilation passage 74 and the gap between the heat exchanger 11 and the radiator 8, namely the radiator gap 19 (see reference) Figure 2 Connected. For example... Figure 3 As shown, the fourth portion 64 of the intake air 60 is drawn in through the first opening 74a and flows downward within the first side ventilation passage 74, flowing into the radiator gap 19. The fourth portion 64 flowing into the radiator gap 19 diffuses upwards, downwards, leftwards, and rightwards within the radiator gap 19, thereby flowing into the radiator 8 from the front surface 8c of the radiator 8, cooling the radiator 8. The cooled fourth portion 64 of the radiator 8 is then blown out from the air outlet 4 towards the outside of the main housing 1.

[0052] The fourth portion 64 of the intake air 60 flows into the radiator 8 through the radiator gap 19 from the first bypass ventilation path 74, thus directing the airflow towards the entire radiator 8 and reducing the cooling deviation of the radiator 8. As a result, the cooling capacity of the radiator 8 is improved, and consequently, the dehumidification capacity of the dehumidification device 100 is increased. Consequently, for the same dehumidification capacity, the power consumption of the dehumidification device can be reduced.

[0053] In this embodiment, the first side ventilation passage 74 communicates with the radiator gap 19 at a lower side than the upper and lower center of the first side ventilation passage 74, but it is not limited to this. It may also communicate with the radiator gap 19 at a higher side than the upper and lower center of the first side ventilation passage 74.

[0054] In this embodiment, a second bypass ventilation path 75 surrounding the second U-shaped tube 81c is also included. The second bypass ventilation path 75 has the same second opening 75a as the first opening 74a. Therefore, the fourth portion 64 flows into the radiator 8 from the first bypass ventilation path 74 and the second bypass ventilation path 75 through the radiator gap 19 from both the left and right sides. As a result, the left-right deviation of the air flowing into the radiator 8 is reduced, and the cooling deviation of the radiator 8 is further reduced. By reducing the cooling deviation, the cooling capacity of the radiator 8 is improved, thus improving the dehumidification capacity of the dehumidification device 100 and further reducing power consumption.

[0055] Furthermore, the radiator 8 is cooled by the first bypass ventilation path 74, the second bypass ventilation path 75, and the fourth part 64, and the heat absorber 10 is cooled by the refrigeration cycle of the dehumidification section 5, thus improving the dehumidification capacity of the dehumidification device.

[0056] In this embodiment, the first opening 74a is located at the upper part of the first side ventilation passage 74, and the second opening 75a is located at the upper part of the second side ventilation passage 75. By placing the first opening 74a and the second opening 75a at the upper part, the upper side of the radiator 8 is at a relatively high temperature, thus improving the cooling capacity of the radiator 8. This, in turn, enhances the dehumidification capacity of the dehumidification device 100 and reduces power consumption.

[0057] As described above, the air intake 2 is located on the side portion 21 of the main housing 1. In this case, air flows easily, the cooling capacity of the radiator 8 is improved, and thus the dehumidification capacity of the dehumidification device 100 can be improved, while reducing power consumption.

[0058] (2) Structure of the second passage of the heat exchanger

[0059] The structure of the second passage 18 of the heat exchanger 11 will be further described in detail below. As described above, the second passage 18 is a longitudinal passage through which the second portion 62 of the air 60 drawn into the heat exchanger 11 passes. To explain in more detail, the second portion 62 flows from the upper side to the lower side in the second passage 18. Furthermore, as... Figure 2 , Figure 4 As shown, within the main housing 1, the blower 6 is positioned closer to the radiator 8 than the absorber 10. Therefore, the airflow in the portion of the second passage 18 closer to the radiator 8 is greater than the airflow closer to the absorber 10. Because the temperature of the radiator 8 is higher than that of the absorber 10, when the airflow in the portion of the second passage 18 closer to the radiator 8 increases and the airflow in the portion of the second passage 18 closer to the absorber 10 decreases, the cooling of the air flowing in the second passage 18 becomes insufficient. As a result, condensation becomes insufficient, and the dehumidification capacity is difficult to improve.

[0060] Figure 7A , Figure 7B This indicates the structure of heat exchanger 11. Figure 7A This indicates the structure of the first layer 110a. Figure 7B This indicates the structure of the second layer 110b. The heat exchanger 11 is constructed by alternating multiple layers of the first layer 110a and the second layer 110b in the y-axis direction (left-right direction). The first layer 110a and the second layer 110b are collectively referred to as layer 110.

[0061] The first layer 110a and the second layer 110b are resin plates with the same shape. Both the first layer 110a and the second layer 110b have a generally trapezoidal shape in the xz plane. The generally trapezoidal shape can include a trapezoidal shape or a shape approximately trapezoidal. For example, the lower edge of each layer 110 slopes upwards from the front to the rear. Within the main body housing 1, as... Figure 2 , Figure 4 As shown, a heat absorber 10 is arranged on the front side (positive x-axis direction) of each layer 110, and a heat sink 8 is arranged on the rear side (negative x-axis direction) of each layer 110. Therefore, the length of the edge portion of each layer 110 opposite to the heat absorber 10 is longer than the length of the edge portion opposite to the heat sink 8.

[0062] Figure 7A The first layer 110a shown includes a first front-back direction path 132a, a second front-back direction path 132b, a third front-back direction path 132c, a fourth front-back direction path 132d, and a fifth front-back direction path 132e, collectively referred to as front-back direction path 132. Furthermore, the number of front-back direction paths 132 included in the first layer 110a is not limited to "5". The front-back direction path 132 is a path extending in the front-back direction, equivalent to the first path 17 described above.

[0063] The first front-rear directional passage 132a includes a first front-rear directional passage inlet opening 134a as a front opening and a first front-rear directional passage outlet opening 136a as a rear opening. Similarly, the second front-rear directional passage 132b includes a second front-rear directional passage inlet opening 134b as a front opening and a second front-rear directional passage outlet opening 136b as a rear opening; the third front-rear directional passage 132c includes a third front-rear directional passage inlet opening 134c as a front opening and a third front-rear directional passage outlet opening 136c as a rear opening; the fourth front-rear directional passage 132d includes a fourth front-rear directional passage inlet opening 134d as a front opening and a fourth front-rear directional passage outlet opening 136d as a rear opening; and the fifth front-rear directional passage 132e includes a fifth front-rear directional passage inlet opening 134e as a front opening and a fifth front-rear directional passage outlet opening 136e as a rear opening. A first portion 61 of the intake air 60 flows into the first front-rear direction passage 132a from the first front-rear direction passage inlet opening 134a and flows out from the first front-rear direction passage outlet opening 136a. Furthermore, the flow of the first portion 61 is the same in the second front-rear direction passage 132b to the fifth front-rear direction passage 132e. Additionally, the first front-rear direction passage inlet opening 134a, the second front-rear direction passage inlet opening 134b, the third front-rear direction passage inlet opening 134c, the fourth front-rear direction passage inlet opening 134d, and the fifth front-rear direction passage inlet opening 134e are collectively referred to as the front-rear direction passage inlet opening 134, and the first front-rear direction passage outlet opening 136a, the second front-rear direction passage outlet opening 136b, the third front-rear direction passage outlet opening 136c, the fourth front-rear direction passage outlet opening 136d, and the fifth front-rear direction passage outlet opening 136e are collectively referred to as the front-rear direction passage outlet opening 136.

[0064] Figure 7B The second layer 110b shown includes a receiver-side passage 112 and a radiator-side passage 122. The receiver-side passage 112 and the radiator-side passage 122 are equivalent to the second passage 18 described above. The receiver-side passage 112 is a passage that allows the front side (the receiver 10 side) to go from the top to the bottom, and the radiator-side passage 122 is a passage that allows the rear side (the radiator 8 side) to go from the top to the bottom.

[0065] The absorber-side passage 112 includes an absorber-side inlet opening 114 as an upper opening and an absorber-side outlet opening 116 as a lower opening. A second portion 62 of the intake air 60 flows into the absorber-side passage 112 from the absorber-side inlet opening 114 and flows out from the absorber-side outlet opening 116.

[0066] The radiator-side passage 122 includes a radiator-side inlet opening 124 as an upper opening and a radiator-side outlet opening 126 as a lower opening. A second portion 62 of the intake air 60 flows into the radiator-side passage 122 from the radiator-side inlet opening 124 and flows out from the radiator-side outlet opening 126.

[0067] As described above, the length of the edge portion of the second layer 110b opposite to the absorber 10 is longer than the length of the edge portion opposite to the radiator 8. Therefore, the vertical length of the absorber-side passage 112 is longer than the vertical length of the radiator-side passage 122. This is to make the heat exchange area of ​​the absorber-side passage 112 larger than the heat exchange area of ​​the radiator-side passage 122.

[0068] In the dehumidification device 100 of this embodiment, in order to prevent the airflow in the radiator-side passage 122 from being greater than the airflow in the absorber-side passage 112, the following measures are taken: Figure 2 , Figure 4 , Figure 8 The opening area adjustment section 130 shown. Figure 8 This is a cross-sectional view showing the structure of the heat exchanger 11 and the opening area adjustment section 130. An opening area adjustment section 130, extending in a plate shape in the front-rear direction, is included above the radiator-side inlet opening 124. The opening area adjustment section 130 does not close the radiator-side inlet opening 124, but by being positioned above the radiator-side inlet opening 124, it partially suppresses the inflow of the second portion 62 into the radiator-side passage 122. On the other hand, the opening area adjustment section 130 is not positioned above the absorber-side inlet opening 114. That is, while it can partially suppress the inflow of the second portion 62 into the radiator-side passage 122, it does not suppress the inflow of the second portion 62 into the absorber-side passage 112, thus allowing the airflow in the radiator-side passage 122 to be smaller than that in the absorber-side passage 112.

[0069] To illustrate the structure of the opening area adjustment section 130 in more detail, the following is also used Figure 9 , Figure 10 . Figure 9 This is a cross-sectional view showing the structure of the dehumidification device 100. Figure 10 This is another cross-sectional view showing the structure of the dehumidification device 100. Figure 9 , Figure 10 All along Figure 1 Cross-sectional view of the dehumidification device 100 of the BB line. Figure 9 It means omitted Figure 5 The structure of the upper protruding part 85a, Figure 10 This indicates that no omissions were made. Figure 5 The structure of the upper protruding part 85a.

[0070] As described above, the main body housing 1 has a first side panel 21a on the right side, a second side panel 21b on the left side, a front panel 22 on the front side, and a rear panel 23 on the rear side. A first air intake 2a is located on the first side panel 21a, and a second air intake 2b is located on the second side panel 21b. On the side of the first air intake 2a of the main body housing 1, a heat absorber 10, a heat exchanger 11, a radiator 8, and a blower 6 are arranged sequentially from the front panel 22 to the rear panel 23. A compressor 7 is located on the side of the second air intake 2b of the main body housing 1 and on the side of the rear panel 23 of the main body housing 1.

[0071] In heat exchanger 11, as described above, a plurality of first layers 110a (not shown) and a plurality of second layers 110b (not shown) alternately overlap in the y-axis direction. Additionally, as... Figure 9 As shown, a receiver-side inlet opening 114 is disposed on the front side of the upper surface of the second layer 110b, and a radiator-side inlet opening 124 is disposed on the rear side of the upper surface of the second layer 110b. Therefore, on the front side of the upper surface of the heat exchanger 11, a plurality of receiver-side inlet openings 114 are arranged in the y-axis direction, and on the rear side of the upper surface of the heat exchanger 11, a plurality of radiator-side inlet openings 124 are arranged in the y-axis direction.

[0072] like Figure 10 As shown, the upper side of the absorber 10 is covered by the upper extension member 85a of the radiator 8. The upper side of the absorber 10 does not contact the upper extension member 85a, therefore a gap (hereinafter referred to as the "upper gap") exists between the upper side of the absorber 10 and the upper extension member 85a. The upper extension member 85a has a rectangular shape. On the front portion of the upper extension member 85a, rectangular openings 86 in the y-axis direction are arranged in the form of "10", and on the rear portion of the upper extension member 85a, rectangular openings 86 in the y-axis direction are arranged in the form of "3". In particular, the rectangular openings 86 on the rear portion are located on the side of the first air intake 2a. The left side of the rectangular openings 86 on the rear portion of the upper extension member 85a, that is, the portion on the rear portion of the upper extension member 85a where no rectangular openings 86 are arranged, corresponds to the aforementioned opening area adjustment section 130. That is, the opening area adjustment part 130 is disposed on the upper side of a portion of the second air intake 2b side in the radiator side inlet opening 124, and not disposed in any part other than that portion.

[0073] Because a rectangular opening 86 is provided above the absorber-side inlet opening 114, the second portion 62 of the intake air 60 easily flows into the absorber-side inlet opening 114. An opening area adjustment section 130 is provided above a portion of the radiator-side inlet openings 124, and rectangular openings 86 are provided above the remaining radiator-side inlet openings 124, making it difficult for the second portion 62 of the intake air 60 to flow into the radiator-side inlet openings 124. Therefore, the airflow in the absorber-side passage 112 is greater than the airflow in the radiator-side passage 122.

[0074] Since the compressor 7 generates heat, it is preferable that the intake air 60 does not flow near the compressor 7. The blower 6 is positioned on the second side portion 21b, so the heat generated by the compressor 7 has little impact on the intake air 60 flowing into the main housing 1 from the first air intake port 2a. Furthermore, the compressor 7 is positioned off-center from the path from the second air intake port 2b towards the absorber 10 and heat exchanger 11, so the heat generated by the compressor 7 also has little impact on the intake air 60 flowing into the main housing 1 from the second air intake port 2b. Moreover, the compressor 7 is positioned closer to the radiator 8 than the absorber 10. Therefore, the heat generated by the compressor 7 also has little impact on the absorber 10.

[0075] The operation of the dehumidification device 100 configured as described herein will be explained. When the blower 6 is operating, intake air 60 is drawn into the main housing 1 through the air intake 2 located on the side portion 21. The intake air 60 is divided into a first part 61, a second part 62, a third part 63, and a fourth part 64. The first part 61 flows into the radiator 8 through the first passage 17 of the absorber 10 and the heat exchanger 11, cooling the radiator 8. The second part 62 flows into the radiator 8 through the second passage 18 of the heat exchanger 11 (absorber side passage 112, radiator side passage 122), cooling the radiator 8.

[0076] The third part 63 flows into the radiator 8 through the third bypass ventilation path 73, bypassing the absorber 10 and the heat exchanger 11, thus cooling the radiator 8. The fourth part 64 flows into the radiator 8 through the radiator gap 19 from the first bypass ventilation path 74 and the second bypass ventilation path 75, bypassing the absorber 10 and the heat exchanger 11, thus cooling the radiator 8. After cooling, the first part 61, the second part 62, the third part 63, and the fourth part 64 are blown out of the main housing 1 through the air outlet 4 by the blower 6.

[0077] The first portion 61 and the second portion 62 of the intake air 60 are cooled in the absorber 10 and heat exchanger 11 of the refrigeration cycle to produce condensation, thereby drying. The dried first portion 61 and the second portion 62 are blown out from the air outlet 4, thereby reducing the humidity of the space surrounding the dehumidification device 100.

[0078] According to this embodiment, because an opening area adjustment section 130 is provided above the radiator-side inlet opening 124, it is difficult for the second portion 62 to flow into the radiator-side inlet opening 124. Furthermore, because the second portion 62 is less likely to flow into the radiator-side inlet opening 124, the airflow in the absorber-side passage 112 can be increased. Additionally, because the airflow in the absorber-side passage 112, which is prone to condensation, is increased, the dehumidification capacity can be improved. Furthermore, because the length of the absorber-side passage 112 is longer than the length of the radiator-side passage 122, the heat exchange area of ​​the absorber-side passage 112 can be larger than that of the radiator-side passage 122. Furthermore, because the heat exchange area of ​​the absorber-side passage 112 is larger than that of the radiator-side passage 122, the dehumidification capacity can be improved. Furthermore, the compressor 7 is positioned on the side of the second air intake 2b, opposite to the side of the first air intake 2a where the absorber 10, heat exchanger 11, and radiator 8 are located. Compared to the absorber 10, it is positioned closer to the radiator 8, thus reducing the impact of heat dissipation from the compressor 7. Additionally, because the impact of heat dissipation from the compressor 7 is reduced, the dehumidification capacity is improved.

[0079] Furthermore, because the opening area adjustment section 130 is disposed on the upper side of a portion of the second air intake 2b side among the multiple radiator-side inlet openings 124, the second portion 62 flowing in from the second air intake 2b is made less likely to flow into the radiator-side inlet opening 124. Additionally, because the second portion 62 flowing in from the second air intake 2b is less likely to flow into the radiator-side inlet opening 124, the airflow in the absorber-side passage 112 can be increased. Furthermore, because the second portion 62 flowing in from the second air intake 2b is less likely to flow into the radiator-side inlet opening 124, the inflow of the second portion 62 from the second air intake 2b, which is more prone to warming than the second portion 62 from the first air intake 2a, can be reduced. Moreover, since the inflow of the second portion 62 from the second air intake 2b, which is more prone to warming than the second portion 62 from the first air intake 2a, is reduced, temperature rise can be suppressed.

[0080] The following is a summary of one aspect of the present invention.
