In addition, the present disclosure includes all combinations of combinable configurations among the configurations described in the following embodiments.

Embodiment 1.

Fig. 1 is a front view of the dehumidifier 1 according to the first embodiment. FIG. 1 shows the appearance of the dehumidifier 1. The dehumidifier 1 is used for the purpose of reducing indoor humidity, for example. Fig. 2 is a sectional view of the dehumidifier 1 according to the first embodiment. Fig. 2 is a cross-section at the A-A position in Fig. 1. Fig. 2 shows the internal structure of the dehumidifier 1 according to the first embodiment.

As shown in FIGS. 1 and 2, the dehumidifier 1 includes a housing 10. The frame 10 is formed so as to be able to stand on its own. A suction port 11 and a blowing port 12 are formed in the housing 10. The suction port 11 is an opening for taking in air from the outside of the casing 10 to the inside. The air outlet 12 is an opening for sending air from the inside of the casing 10 to the outside.

In this embodiment, the suction port 11 is formed on the back surface of the housing 10. The air outlet 12 is formed on the upper surface of the housing 10. The suction port 11 and the blowing port 12 may be provided at arbitrary places. For example, the suction port 11 may be formed in the side surface of the housing 10. The suction port 11 is not formed in the dehumidifier 1 on the back surface of the frame 10, and is usable when the back surface of the frame 10 is in contact with or close to the wall.

The dehumidifier 1 is an example of a blower mechanism, and includes a blower fan 21. The blower fan 21 is housed inside the casing 10. An air path is formed in the casing 10 from the suction port 11 to the blowout port 12. The blower fan 21 is arranged in this air passage. The blower fan 21 is a device that takes in air to the inside of the casing 10 and sends the taken-in air to the outside of the casing 10.

The dehumidifier 1 includes an evaporator 31, a compressor 32, a condenser 33a, and a condenser 33b. The evaporator 31, the compressor 32, the condenser 33a, and the condenser 33b are housed inside the casing 10 as shown in FIG.

The dehumidifier 1 of this embodiment includes a dehumidification mechanism. The so-called dehumidifier means a person for removing moisture from the air. The dehumidification mechanism is constituted by a heat medium circuit. The so-called heat medium circuit refers to a circuit in which a heat medium is circulated. Fig. 3 is a diagram schematically showing a heat medium circuit according to the first embodiment. As shown in FIG. 3, the heat medium circuit of this embodiment is composed of an evaporator 31, a compressor 32, a condenser 33a, a condenser 33b, and a pressure reducing device 34.

A heat medium flows through the evaporator 31, the compressor 32, the condenser 33a, the condenser 33b, and the decompression device 34. The evaporator 31, the compressor 32, the condenser 33a, the condenser 33b, and the decompression device 34 are connected in a ring shape through a pipe through which a heat medium flows.

The evaporator 31, the condenser 33a, and the condenser 33b are heat exchangers for exchanging heat between a heat medium and air. The compressor 32 is a device for compressing a heat medium. The decompression device 34 is a device for decompressing a heat medium. The pressure reducing device 34 is, for example, an expansion valve or a capillary tube.

The evaporator 31, the compressor 32, the condenser 33a, the condenser 33b, and the decompression device 34 each have an inlet and an outlet of a heat medium. The outlet of the evaporator 31 is connected to the inlet of the compressor 32. The heat medium that has passed through the evaporator 31 flows into the compressor 32. The compressor 32 is a heat medium that is compressed after flowing into the compressor 32. The heat medium compressed by the compressor 32 flows out from the outlet of the compressor 32.

The outlet of the compressor 32 is connected to the inlet of the condenser 33b. The outlet of the condenser 33b is connected to the inlet of the condenser 33a. The heat medium compressed by the compressor 32 passes through the condenser 33a and the condenser 33b.

The outlet of the condenser 33a is connected to the inlet of the decompression device 34. The heat medium passing through the condenser 33a and the condenser 33b flows into the decompression device 34. The decompression device 34 is a heat medium that flows into the decompression device 34 under reduced pressure. The heat medium that has been decompressed by the decompression device 34 expands.

An outlet of the pressure reducing device 34 is connected to an inlet of the evaporator 31. The heat medium decompressed by the decompression device 34 flows into the evaporator 31. In this embodiment, the heat medium passes through the evaporator 31, the compressor 32, the condenser 33b, the condenser 33a, and the decompression device 34 in this order. The heat medium after passing through the pressure reducing device 34 passes through the evaporator 31 again. In this embodiment, the heat medium circulates in the heat medium circuit in this manner. In addition, the connection order of the condenser 33a and the condenser 33b in the heat medium circuit may be reversed.

Fig. 4 is a diagram schematically showing an internal air path of the casing of the first embodiment. Fig. 4 is equivalent to a part of the cross-sectional view of Fig. 2. With reference to Figs. 2 and 4, the structure of the air passage formed in the casing 10 and the components arranged in the air passage will be described in detail.

The evaporator 31, the condenser 33a, and the condenser 33b, which form the heat medium circuit, are arranged in the air path from the suction port 11 to the blowout port 12, as shown in Figs. 2 and 4. In this embodiment, the evaporator 31, the condenser 33a, and the condenser 33b are arranged between the blower fan 21 and the suction port 11.

The condenser 33 b is located in an air path from the suction port 11 to the blow-out port 12, and is disposed on the upstream side of the blower fan 21. The condenser 33a is located in the air path from the suction port 11 to the blowout port 12, and is arranged upstream of the condenser 33b. The condenser 33a and the condenser 33b are juxtaposed in a state adjacent to each other.

A gap is set between the condenser 33a and the condenser 33b. In the present disclosure, this gap is referred to as a mixing space 41. That is, a mixing space 41 is formed between the condenser 33 a and the condenser 33 b inside the housing 10. The mixing space 41 is formed in the air path from the suction port 11 to the air outlet 12, and is formed upstream of the condenser 33b.

The air path from the inlet 11 to the air outlet 12 includes a first air path and a second air path. In other words, the first air passage and the second air passage are formed inside the casing 10. The first air path system is formed so that a part of the air taken in by the fan 21 into the inside of the casing 10 passes through the air paths of the evaporator 31 and the condenser 33b in this order. The second air path system is formed so that a part of the air taken into the housing 10 by the blower fan 21 passes through the air path of the condenser 33 b without passing through the evaporator 31.

A dehumidifying air path 42 as an example of the first air path is formed inside the casing 10 of this embodiment. In the casing 10 of this embodiment, a side ventilation path 43 is formed as an example of the second air path. As shown in FIG. 2 and FIG. 4, the dehumidification air path 42 and the side ventilation path 43 are air paths from the suction port 11 to the mixed space 41, respectively.

The dehumidification air path 42 is formed so that a part of the air taken in by the fan 21 into the interior of the casing 10 passes through the evaporator 31, the condenser 33a, and the condenser 33b in this order. The evaporator 31 and the condenser 33 a are arranged in the dehumidifying air path 42. The dehumidifying air path 42 passes through the evaporator 31 and the condenser 33 a and reaches the mixing space 41 from the suction port 11.

The side ventilation path 43 is formed so that a part of the air taken into the housing 10 by the fan 21 does not pass through the evaporator 31 and the condenser 33a and passes through the condenser 33b. The bypass air passage 43 is formed so as to bypass the evaporator 31 and the condenser 33a. The side ventilation path 43 passes through the evaporator 31 and the condenser 33a and passes from the suction port 11 to the mixing space 41.

The dehumidifying air path 42 as an example of the first air path and the bypass air path 43 as an example of the second air path are formed by any method. As an example, a partition member 50 is provided inside the casing 10. The partition member 50 is a member that divides the dehumidification air path 42 and the bypass air path 43. The partition member 50 has a flat plate shape, for example.

In this embodiment, as shown in FIGS. 2 and 4, the partition member 50 is provided above the evaporator 31 and the condenser 33 a. The dehumidifying air path 42 is formed below the partition member 50. The side ventilation path 43 is formed above the partition member 50. In the present embodiment, the bypass air passage 43 is formed above the evaporator 31 and the condenser 33a. The dehumidifying air path 42 and the bypass air path 43 in this embodiment are formed by the frame body 10 and the partition member 50.

The frame body 10 and the partition member 50 may be formed integrally. The dehumidifying air path 42 and the bypass air path 43 may be formed by any method as described above. The partition member 50 may not be provided inside the housing 10. The dehumidifying air path 42 and the bypass air path 43 may be formed by members other than the frame body 10 and the partition member 50.

Next, the operation of the dehumidifier 1 according to this embodiment will be described with reference to Figs. 2 and 4. The arrows in Figures 2 and 4 indicate the flow of air when the dehumidifier 1 is operating.

The dehumidifier 1 operates by rotating the fan 21. The dehumidifier 1 is used indoors, for example. When the blower fan 21 rotates, the airflow from the suction port 11 to the blowout port 12 is generated inside the casing 10. The fan 21 is borrowed to generate airflow, whereby the indoor air A1 is taken in from the suction port 11 to the inside of the housing 10.

The air A1 taken into the inside of the casing 10 is divided into a dehumidifying air path 42 and a bypass air path 43. The air A2, which is a part of the air A1, is guided to the dehumidifying air path 42. The air A3, which is a part of the air A1, is guided to the side ventilation path 43. The air A3 is the part of the air A1 taken into the inside of the casing 10 and other than the air A2 guided to the dehumidifying air path 42.

The air A2 guided to the dehumidifying air path 42 passes through the evaporator 31. Heat is exchanged between the air A2 passing through the evaporator 31 and the heat medium flowing through the evaporator 31. As described above, the heat medium decompressed by the decompression device 34 flows to the evaporator 31. A heat medium having a lower temperature than the air A1 taken into the casing 10 flows to the evaporator 31. The heat medium flowing in the evaporator 31 absorbs heat from the air A2 passing through the evaporator 31.

The air A2 passing through the evaporator 31 absorbs heat by a heat medium flowing through the evaporator 31. The air A2 passing through the evaporator 31 is cooled by a heat medium flowing through the evaporator 31. As a result, dew condensation occurs. That is, the moisture contained in the air A2 is condensed. The condensed water is removed from the air A2. The moisture removed from the air A2 is, for example, stored in a water storage tank 13 provided inside the casing 10.

The air A2 after the moisture is removed by the evaporator 31 passes through the condenser 33a. Heat is exchanged between the air A2 passing through the condenser 33a and the heat medium flowing through the condenser 33a. The heat medium flowing through the condenser 33a is cooled by the air A2 passing through the condenser 33a.

The air A2 passing through the condenser 33a is heated by the heat medium flowing through the condenser 33a. The air A2 after passing through the condenser 33a reaches the mixing space 41. In this way, the air A2 guided to the dehumidifying air path 42 is transmitted through the evaporator 31 and the condenser 33a, and the conventional mixing space 41 is transported.

The air A3 guided by the bypass air passage 43 is conveyed to the mixing space 41 without passing through the evaporator 31 and the condenser 33a, as shown in FIG. The air A2 after passing through the dehumidifying air path 42 and the air A3 after passing through the bypass air path 43 are sent to the mixing space 41.

In the mixing space 41, the air A2 after passing through the dehumidifying air path 42 and the air A3 after passing through the bypass air path 43 are mixed. The air A2 and the air A3 are mixed, whereby the mixed air B1 is generated. As shown in FIG. 4, the mixed air B1 passes through the condenser 33b. Heat is exchanged between the mixed air B1 passing through the condenser 33b and the heat medium flowing through the condenser 33b. The heat medium flowing through the condenser 33b is cooled by the mixed air B1 passing through the condenser 33b.

The mixed air B1 passing through the condenser 33b is heated by the heat medium flowing through the condenser 33b. The mixed air B1 is heated by the heat medium, thereby generating dry air B2. The dry air B2 is air that is drier than the indoor air A1. The dry air B2 passes through the fan 21. The dry air B2 after passing through the blower 21 is sent out from the blower outlet 12 to the outside of the casing 10. In this way, the dehumidifier 1 supplies dry air B2 to the outside of the dehumidifier 1.

The structure of the dehumidifier 1 of this embodiment is a part of the air taken into the inside of the casing 10 and passes through the evaporator 31, the condenser 33a, and the condenser 33b in this order. The structure of the dehumidifier 1 is a part of the air taken into the inside of the casing 10 and passes through the condenser 33b without passing through the evaporator 31. In the case of the dehumidifier 1 according to this embodiment, by the above-mentioned configuration, the air volume of the air passing through the evaporator 31 and the air volume of the air passing through the condenser 33b can be adjusted respectively.

In the present embodiment, a mixing space 41 is formed inside the housing 10. In the mixing space 41, the air A2 and the air A3 are mixed, whereby the mixed air B1 is generated. In this embodiment, the air A2 and the air A3 having a temperature difference do not pass through the condenser 33b, and the mixed air B1 passes through the condenser 33b. The heat medium flowing in the condenser 33b is efficiently cooled by the mixed air B1. In the present embodiment, the heat medium is efficiently cooled, so the energy efficiency of the dehumidifier 1 becomes better.

In the mixing space 41, the air A2 and the air A3 are mixed, whereby the dry air B2 at a relatively appropriate temperature is blown out from the blow-out port 12. According to this embodiment, it is possible to prevent the excessively low-temperature air or the excessively high-temperature air from being blown out. According to this embodiment, the discomfort of the user of the dehumidifier 1 can be reduced.

The evaporator 31, the condenser 33a, and the condenser 33b in the above embodiment may be, for example, flat plates. The flat plate-shaped evaporator 31 and the condenser 33a are arranged so that the surface having the largest area is approximately perpendicular to the flow direction of the air A2. The flat-plate evaporator 31 and the condenser 33a are exemplified as being arranged parallel to each other. Moreover, the flat-plate-shaped condenser 33b is taken as an example, and it may be arrange | positioned in parallel with the flat-plate-shaped evaporator 31 and the condenser 33a.

For example, the interval between the condenser 33a and the condenser 33b may be made larger than the interval between the evaporator 31 and the condenser 33a. That is, the mixing space 41 may be formed to be wider than the gap formed between the evaporator 31 and the condenser 33a. Thereby, in the mixing space 41, the air A2 and the air A3 are mixed more uniformly. The mixing space 41 is formed wide, whereby the temperature distribution of the mixed air B1 becomes uniform. The temperature distribution of the mixed air B1 becomes uniform, whereby the heat medium flowing through the condenser 33b is efficiently cooled by the mixed air B1. Thereby, the efficiency of heat exchange in the condenser 33b becomes better.

In the above-mentioned embodiment, the bypass air passage 43 is formed above the evaporator 31 and the condenser 33a. The side ventilation path 43 is located at an upper portion inside the casing 10. As shown in FIGS. 2 and 4, the side ventilation path 43 is located at the same level as the upper portion of the condenser 33 b. Here, the heat medium may flow through the condenser 33b from the top to the bottom. The bypass air passage 43 may be arranged on the upstream side in the flow of the heat medium in the condenser 33b. There is a large temperature difference between the high-temperature heat medium flowing on the upstream side in the condenser 33b and the air A3 passing through the bypass passage 43. The temperature difference between the heat medium and the air A3 becomes larger, whereby the efficiency of heat exchange in the condenser 33b becomes better.

As shown in FIGS. 2 and 4, the upper end of the condenser 33 b may be higher than the upper end of the condenser 33 a. Thereby, as shown in the said embodiment, it becomes possible to arrange the side ventilation path 43 above the evaporator 31 and the condenser 33a. The side ventilation path 43 arranged above the evaporator 31 and the condenser 33a is, for example, a U-shaped joint installed on the evaporator 31 and the condenser 33a, and passes from the suction port 11 to the mixing space 41. In addition, the side ventilation path 43 disposed above the evaporator 31 and the condenser 33a is not connected to the piping ground connecting the evaporator 31, the compressor 32, the condenser 33a, the condenser 33b, and the pressure reducing device 34, and is provided from the suction port 11 reached the mixed space 41. There are no obstacles in the side ventilation path 43, thereby making it easy to make the amount of air flow of the air A3 flowing in the side ventilation path 43 a proper amount.

FIG. 5 is a diagram schematically illustrating a modification example of the internal air path of the casing 10 according to the first embodiment. Figure 5 corresponds to Figure 4. As shown in FIG. 5, the condenser 33 a may be disposed in the side ventilation path 43. In the modification shown in FIG. 5, the air A3 passes through the condenser 33 a and the condenser 33 b in this order without passing through the evaporator 31. The condenser 33 a is provided in the side ventilation path 43, whereby the dehumidifier 1 can be made smaller.

As shown in FIGS. 4 and 5, the condenser 33 b may be formed larger than the evaporator 31 and the condenser 33 a. By the difference between the sizes of the evaporator 31 and the condenser 33a and the size of the condenser 33b, a space can be formed inside the casing 10. With this space, the side ventilation path 43 can be easily formed. The evaporator 31, the condenser 33a, and the condenser 33b may be the same size as each other. The side ventilation path 43 may be arranged in a state where the evaporators 31, the condensers 33a, and the condensers 33b of the same size are deviated from each other.

The suction port 11 may be formed on the upper surface or the side surface of the housing 10, for example. When the suction port 11 is formed on the side of the casing 10, the center of the condenser 33 b may be arranged closer to the side of the casing 10 than the center of the casing 10. By using the condenser 33b close to the suction port 11, the pressure loss from the suction port 11 to the condenser 33b can be reduced. In the same manner, the evaporator 31 and the condenser 33 a may be brought closer to the side surface of the housing 10. Thereby, the side ventilation path 43 can be formed in the side of the evaporator 31 and the condenser 33a. In this case, it becomes possible to make the height dimension of the dehumidifier 1 small.

Similarly, when the suction port 11 is formed on the upper surface of the casing 10, the center of the condenser 33 b may be disposed closer to the upper surface of the casing 10 than the center of the casing 10. Moreover, the evaporator 31 and the condenser 33a may be brought close to the upper surface of the housing 10. Thereby, the side ventilation path 43 can be formed below the evaporator 31 and the condenser 33a. In this case, it becomes possible to make the width and depth of the dehumidifier 1 small.

Embodiment 2.

Next, the dehumidifier 1 according to the second embodiment will be described focusing on the differences from the first embodiment. The same or corresponding parts as those in the first embodiment are given the same reference numerals, and the description is simplified or omitted. The appearance of the dehumidifier 1 according to this embodiment is the same as that of the first embodiment, and is shown in FIG. 1. FIG. 6 is a diagram schematically showing an internal air path of the housing 10 according to the second embodiment. Fig. 6 corresponds to Fig. 4 in the first embodiment. Fig. 7 is a diagram schematically showing a heat medium circuit according to the second embodiment.

The dehumidifier 1 according to the first embodiment includes a condenser 33a and a condenser 33b. That is, the dehumidifier 1 according to the first embodiment includes a plurality of condensers. The dehumidifier 1 of this embodiment does not include a condenser 33a. As shown in FIG. 6, the mixing space 41 is formed between the evaporator 31 and the condenser 33b. The heat medium circuit of this embodiment is formed by an evaporator 31, a compressor 32, a condenser 33b, and a pressure reducing device 34, as shown in FIG.

In this embodiment, the dehumidifying air path 42 is formed so that the air A2 that is a part of the air A1 taken into the inside of the housing 10 by the fan 21 passes through the evaporator 31 and the condenser 33b in this order. The dehumidifying air path 42 passes through the evaporator 31 and the condenser 33 a and reaches the mixing space 41 from the suction port 11.

Further, in this embodiment, the bypass air passage 43 is formed so that the air fan A21 takes part of the air A1 in the air A1 inside the casing 10 and passes through the condenser 33b without passing through the evaporator 31. The bypass ventilation path 43 is a bypass evaporator 31 and reaches the mixing space 41 from the suction port 11.

The structure of the dehumidifier 1 in this embodiment is a part of the air taken into the inside of the casing 10 and passes through the evaporator 31 and the condenser 33b in this order. The dehumidifier 1 of the present embodiment is the same as that of the first embodiment, and a part of the air taken into the inside of the casing 10 passes through the condenser 33b without passing through the evaporator 31. According to this embodiment, similarly to the first embodiment, the air volume of the air passing through the evaporator 31 and the air volume of the air passing through the condenser 33b can be set to appropriate amounts, respectively.

Fig. 8 is a diagram schematically showing a first modification of the internal air path of the casing 10 according to the second embodiment. As shown in FIG. 8, the housing 10 may be formed with a first opening 11 a and a second opening 11 b instead of the suction port 11. The first opening 11 a is formed on the back surface of the housing 10. The second opening 11 b is formed on the upper surface of the housing 10. The first opening 11a and the second opening 11b are openings for taking in air from the outside of the casing 10 to the inside. According to the present modification, there are a plurality of openings for taking in air from the outside of the housing 10 to the inside, whereby the air volume of the air passing through the condenser 33b can be increased.

The air taken in from the first opening 11a corresponds to the drawings in Embodiment 1 and the air A2 in FIG. 6 in this embodiment. The air A2 taken in from the first opening 11a passes through the evaporator 31 and the condenser 33b in this order. The air taken in from the second opening 11b corresponds to the air A3 in each diagram of the first embodiment and the sixth diagram of the present embodiment. The second opening 11b is formed so that the air A3 taken in from the second opening 11b passes through the condenser 33b without passing through the evaporator 31. For example, when the evaporator 31 and the condenser 33b are juxtaposed in the horizontal direction, the position of the second opening 11b in the horizontal direction is between the evaporator 31 and the condenser 33b. In the modified example shown in FIG. 8, similarly to the above-mentioned embodiment shown in FIG. 6, the air volume of the air passing through the evaporator 31 and the air volume of the air passing through the condenser 33 b can be adjusted respectively. .

Fig. 9 is a diagram schematically showing a second modification of the internal air passage of the casing of the second embodiment. Fig. 9 is a diagram schematically showing a cross section at a position B-B in Fig. 1. As shown in FIG. 9, the second openings 11 b may be formed in plural. As shown in FIG. 9, the second opening 11 b may be formed on the side surface of the frame body 10.
