Next, with reference to FIGS. 2 and 4, it will be described dividing operation of the dehumidifier 1 of the present embodiment. The arrows in FIGS. 2 and 4 show the flow of air when the dehumidifier 1 is operating.

Dehumidifier 1, the blower fan 21 is operated by rotating. Dehumidifier 1 is used, for example, indoors. When the blower fan 21 rotates, airflow flowing from suction port 11 to the outlet 12 is generated inside the casing 10. By air flow is generated by the blower fan 21, indoor air A1 is taken in from the suction port 11 into the housing 10.

Air A1 taken into the housing 10, which is branched into a removal Shimekazero 42 and the bypass air passage 43. Air A2 is a part of the air A1 is introduced into the dividing Shimekazero 42. The air A3 is a part of the air A1 is guided to the bypass air passage 43. Air A3, of the air A1 taken into the housing 10, a portion other than the air A2 guided to the dividing Shimekazero 42.

Air A2 guided to the dividing Shimekazero 42, it passes through the evaporator 31. Heat is exchanged between the heat medium flowing through the air A2 and the evaporator 31 which passes through the evaporator 31. The evaporator 31, as described above, the heat medium was reduced by vacuum device 34 flows. The evaporator 31 flows a low temperature of the heat medium than air A1 taken into the housing 10. Heat medium flowing through the evaporator 31 absorbs heat from the air A2 passing through the evaporator 31.

Air A2 passing through the evaporator 31, is absorbed by the heat medium flowing through the evaporator 31. Air A2 passing through the evaporator 31 is cooled by the heat medium flowing through the evaporator 31. As a result, condensation occurs. That is, moisture contained in the air A2 is condensed. Condensed water is removed from the air A2. Water removed from the air A2 is, for example, accumulated in the water storage tank 13 provided inside the housing 10.

Air A2 which moisture has been removed by the evaporator 31, passes through the condenser 33a. Heat is exchanged between the heat medium flowing through the air A2 and the condenser 33a which passes through the condenser 33a. Heat medium flowing through the condenser 33a is cooled by the air A2 passing through the condenser 33a.

Air A2 passing through the condenser 33a is heated by the heat medium flowing through the condenser 33a. Air A2 passing through the condenser 33a leads to the mixing space 41. Thus, air A2 guided to the dividing Shimekazero 42 is delivered to the mixing space 41 through the evaporator 31 and condenser 33a.

The air A3 guided to the bypass air passage 43, as shown in FIG. 4, it is fed into the mixing space 41 without passing through the evaporator 31 and condenser 33a. The mixing space 41 includes an air A3 passing through the air A2 and the bypass air passage 43 passing through the dividing Shimekazero 42 is sent.

In the mixing space 41, the air A3 passing through the air A2 and the bypass air passage 43 passing through the dividing Shimekazero 42 are mixed. By the air A2 and the air A3 are mixed, the mixing air B1 is generated. Mixed air B1, as shown in FIG. 4, passes through the condenser 33b. Heat is exchanged between the heat medium flowing through the mixed air B1 and the condenser 33b which passes through the condenser 33b. Heat medium flowing through the condenser 33b is cooled by mixing air B1 passing through the condenser 33b.

Mixed air B1 passing through the condenser 33b is heated by the heat medium flowing through the condenser 33b. By mixing air B1 is heated by the heat medium, dry air B2 is generated. Dry air B2 is an air dry state than indoor air A1. Dry air B2 passes through the blower fan 21. Dry air B2 passing through the blower fan 21, the air outlet 12 is fed to the outside of the housing 10. In this way, the dehumidifier 1 supplies the dry air B2 to the outside of the dehumidifier 1.

Dehumidifier 1 of the present embodiment, part of the air taken into the housing 10 is configured to pass through the evaporator 31, the condenser 33a and the condenser 33b sequentially. Furthermore, the dehumidifier 1, a part of the air taken into the housing 10 is configured to pass through the condenser 33b without passing through the evaporator 31. If dehumidifier 1 of the present embodiment, the above structure, it is possible to respectively suitable amounts and the amount of air passing through the air volume and the condenser 33b of the air passing through the evaporator 31.

In this embodiment, inside the housing 10, the mixing space 41 is formed. In the mixing space 41 by the air A2 and the air A3 are mixed, the mixing air B1 is generated. In this embodiment, the air A2 and the air A3 with a temperature difference rather than passing through the separate condenser 33b, mixed air B1 passes through the condenser 33b. Heat medium flowing through the condenser 33b is efficiently cooled by mixing air B1. If this embodiment, the heat medium is efficiently cooled, energy efficiency of the dehumidifier 1 becomes better.

Also, by the air A2 and the air A3 are mixed in the mixing space 41, dry air B2 more suitable temperature is blown out from the air outlet 12. According to this embodiment, are excessively cold air or excessively prevented from high temperature air is blown out. According to this embodiment, user discomfort dehumidifier 1 is further reduced.

Evaporator 31 in the above embodiment, the condenser 33a and the condenser 33b is, for example, be a flat plate. Flat evaporator 31 and condenser 33a, the surface having the largest area, are arranged so as to be substantially perpendicular to the direction of the flow of air A2. Flat evaporator 31 and condenser 33a, as an example, are arranged parallel to one another. Tabular condenser 33b, as an example, may be arranged parallel to the plate-shaped evaporator 31 and condenser 33a.

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

In the above embodiment, the bypass air passage 43 is formed above the evaporator 31 and condenser 33a. Bypass air passage 43 is located above the interior of the housing 10. Bypass air passage 43, as shown in FIGS. 2 and 4, it is located at the height of the top and comparable condenser 33b. Here, the condenser 33b, may be heat medium flows from the top to the bottom. Bypass air passage 43 may be disposed on the upstream side in the flow of the heat medium in the condenser 33b. Between the air A3 passing through the high temperature heat medium and the bypass air passage 43 through the upstream side of the condenser 33b, there is a large temperature difference. By the temperature difference between the heat medium and the air A3 is increased, the heat exchange efficiency becomes better in the condenser 33b.

Further, as shown in FIGS. 2 and 4, the upper end of the condenser 33b may be higher than the upper end of the condenser 33a. Thus, as shown in the above embodiment, the bypass air passage 43 can be arranged above the evaporator 31 and condenser 33a. Evaporator 31 and condenser bypass air path 43 disposed above 33a, for example, from the suction port 11 without passing through the U-shaped fitting which is attached to the evaporator 31 and condenser 33a into the mixing space 41 throughout. Further, evaporator 31 and condenser bypass air path 43 disposed above 33a is an evaporator 31, a compressor 32, a condenser 33a, the suction port without passing through the pipe connecting the condenser 33b and decompressor 34 ranging from 11 to the mixing space 41. By obstacle disappears bypass air passage 43, it becomes easy to suitable amount volume of air A3 flowing through the bypass air passage 43.

Figure 5 is a diagram schematically showing a modified example of the internal air passage of the housing 10 of the first embodiment. Figure 5 is a view corresponding to FIG. Condenser 33a, as shown in FIG. 5, may be disposed in the bypass air passage 43. Air A3 in the modification shown in Figure 5, passes through the condenser 33a and the condenser 33b in order without passing through the evaporator 31. By condenser 33a is provided in the bypass air passage 43 can be the dehumidifier 1 more compact.

Further, as shown in FIGS. 4 and 5, the condenser 33b may be larger than the evaporator 31 and condenser 33a. The difference between the magnitude of the size of the evaporator 31 and condenser 33a and the condenser 33b, it is possible to form a space inside the casing 10. This space makes it possible to more easily form a bypass air passage 43. Incidentally, the evaporator 31, the condenser 33a and the condenser 33b may be comparable in size to each other. Bypass air passage 43 may be formed by an evaporator 31 of the same order of magnitude as the condenser 33a and the condenser 33b are arranged with a shift from each other.

Moreover, the suction port 11, for example, may be formed on the upper surface or side surface of the housing 10. If the suction port 11 is formed on the side surface of the housing 10, the center of the condenser 33b may be disposed along the side of the casing 10 than the center of the housing 10. By the condenser 33b approaches the suction port 11, it is possible to reduce the pressure loss in the suction port 11 to the condenser 33b. Similarly, the evaporator 31 and the condenser 33a may be closer to the side surface of the housing 10. Thus, it is possible to form a bypass air passage 43 on the side of the evaporator 31 and the condenser 33a. In this case, it is possible to further reduce the height dimension of the dehumidifier 1.

Similarly, if the suction port 11 is formed on the upper surface of the housing 10, the center of the condenser 33b may be arranged close to the upper surface of the housing 10 from the center of the housing 10. Further, the evaporator 31 and the condenser 33a may be closer to the upper surface of the housing 10. Thus, it is possible to form a bypass air passage 43 below the evaporator 31 and the condenser 33a. In this case, it is possible to further reduce the width and depth of the dehumidifier 1.
