  Further, the back surface portion 2C of the dehumidifier body 2 has a first intake port 6 that is an intake port on the condenser side and a second intake port that is an intake port on the evaporator side below the second air outlet 4 from above. The air ports 7 are formed in this order, and an air filter is interposed in the first air inlet 6 and the second air port 7.

The second damper 13 is provided as the condenser side switching means.

  Further, in the substantially central portion of the dehumidifier body 2, the dehumidifier body is disposed on the front side where the first blower fan 10 and the second blower fan 12 are disposed and on the rear side where the evaporator 9 and the condenser 8 are disposed. 2 is provided with a partition wall 14 for partitioning the inside. The partition wall 14 has a ventilation hole (not shown) through which air can flow at least between the evaporator 9 side and the first blower fan 10 side, and between the condenser 8 side and the second blower fan 12. It is assumed that a vent hole (not shown) through which air can flow is provided.

  Further, on the front side of the partition wall 14, an evaporator-side scroll portion that is provided in a spiral shape on the outer periphery of the first blower fan 10 and has an evaporator-side opening 15 that communicates with the first air outlet 3 at the top. 16 and a condenser-side scroll portion 18 that is provided in a spiral shape on the outer periphery of the second blower fan 12 and has a condenser-side opening 17 that communicates with the first air outlet 3 at the top thereof. It is erected.

  Here, in the gap between the first blower fan 10 and the evaporator-side scroll portion 16, an evaporator-side blower passage 19 through which air from the evaporator 9 side can flow is formed, and the second blower fan. A condenser-side air passage 20 through which air from the condenser 8 side can flow is also formed in the gap between the condenser 12 and the condenser-side scroll portion 18.

  Here, the evaporator-side air passage 19 refers to the first air outlet 3 or the second air outlet 2 via the second air port 7, the evaporator 9, and the evaporator-side scroll portion 16 by the first air fan 10. This is a path through which the air guided to the blower outlet 4 flows, and the condenser side blowing path 20 is a first air inlet 6, a condenser 8, and a condenser side scroll by a second blower fan 12. It is a path through which air guided to the first air outlet 3 or the second air outlet 4 through the section 18 flows.

  Further, the through portion 21 formed in the upper portion of the partition wall 14 can communicate with the evaporator-side air passage 19 and the condenser-side air passage 20 with the common portion 22 at the upper portion of the scroll portions 16 and 18 as a boundary. A plurality of guide plates 25 that are partitioned by the evaporator-side through-portion 23 and the condenser-side through-portion 24 and are formed in parallel with the horizontal direction allow air from the air blowing paths 19, 20 to flow into the second air outlet 4. It can be distributed to

  On the further back side 2C side of the guide plate 25 on the evaporator 9 side, a cutout portion 26 formed by cutting out into a rectangular shape is provided.

  Here, the first damper 11 is pivotally pivoted vertically on the right side of the upper end of the partition wall 14 so that the evaporator side opening 15 and the evaporator side through part 23 can be selectively opened and closed. By being provided, the air outlet from the evaporator-side air passage 19 can be switched to the first air outlet 3 or the second air outlet 4. Further, the second damper 13 is pivotally provided on the left side of the upper end of the partition wall 14 so as to be pivotable in the vertical direction so that the condenser side opening 17 and the condenser side through part 24 can be selectively opened and closed. As a result, the air outlet from the condenser side blowing path 20 can be switched to the first outlet 3 or the second outlet 4.

  A part of the lower part of the damper main body is notched in the second damper 13 according to the wall surface shape of the condenser side scroll part 18, and the notch part is pivotally pivoted in the vertical direction via the hinge part 27. A folded piece 28 is provided.

  In addition, a switch (not shown) for switching the operation mode is attached to the operation unit 29 provided on the upper surface 2A of the main body 2, and a control means (not shown) is operated by operating this switch. And controlling the driving means (not shown) such as a motor of each of the first damper 11 and the second damper 13 and controlling the rotating operation of the first damper 11 and the second damper 13. The blowout air coming out from the first air outlet 3 is configured to be switchable such that only cold air, only warm air, or both cold air and hot air are used.

  Thus, in the dehumidifier 1 of the present embodiment, the above-described operation mode can be selected from the cold air operation mode, the hot air operation mode, and the normal dehumidification operation mode by the switch (not shown) provided in the operation unit 29. ing. Each operation mode will be described below.

  First, in the cold air operation mode, the first damper 11 closes the evaporator-side through portion 23 and the second damper 13 closes the condenser-side opening 17 to evaporate from the first outlet 3. The air (cold air) from the condenser side blowing path 19 is discharged, and the air (warm air) from the condenser side blowing path 20 is discharged from the second outlet 4.

  Next, in the warm air operation mode, the first blower outlet 3 is closed by closing the evaporator side opening 15 with the first damper 11 and closing the condenser side through part 24 with the second damper 13. The air (warm air) from the condenser side air passage 20 is discharged from the air outlet, and the air (cold air) from the evaporator side air passage 19 is discharged from the second outlet 4.

  Here, in the warm air operation mode, the first damper 11 closes the evaporator-side opening 15 so that the air (cold air) flowing through the evaporator-side air passage 19 is changed to the first damper 11 and the evaporator side. There is a bypass path 30 that circulates through the through part 23, the guide plate 25, and the notch part 26 in order, and joins the air (cold air) that has exited from the notch part 26 that is the outlet thereof to the upstream side of the condenser side blowing path 20 It is formed.

  Subsequently, in the dehumidifying operation mode, the evaporator-side through portion 23 or the evaporator-side opening 15 is appropriately closed by the first damper 11, and the condenser-side through-portion 24 or the condenser-side opening is closed by the second damper 13. By appropriately closing the portion 17, air from the first air outlet 3 from the evaporator side air passage 19 (cold air), air from the condenser side air passage 20 (warm air), or the cold air and the hot air Any wind that consists of both of them will be discharged.

  The operation of the dehumidifier 1 having the above configuration will be described. When the operation unit 29 is operated to start operation, the control means (not shown) drives the compressor (not shown) of the refrigeration cycle, the first blower fan 10 and the second blower fan 12. Then, the operation of the dehumidifier 1 starts. During operation, the driven first blower fan 10 cools and dehumidifies the indoor air taken in from the second intake port 7 by touching the evaporator 9, and passes through the evaporator-side blower passage 19 to form the first blowout port. 3 or the second outlet 4 is discharged as dry cold air after dehumidification.

  In addition, the indoor air taken in from the first air inlet 6 is heated by the condenser 8 by the driven second blower fan 12, and the first air outlet 3 or the second air is passed through the condenser side air passage 20. It is discharged as warm air from the air outlet 4. And the dew condensation water dehumidified by this evaporator 9 is discharged | emitted to the tank (not shown) with which the dehumidifier 1 lower part was equipped.

  Then, the case where the operation part 29 is operated and the operation mode of the dehumidifier 1 is switched is demonstrated. When the cold air operation mode is selected, the cold air that has passed through the evaporator 9 is discharged from the first air outlet 3, and the hot air that has passed through the condenser 8 is discharged from the second air outlet 4.

  In this cold air operation mode, when the user approaches the first air outlet 3, the cool air blown from the first air outlet 3 can give the user a cool feeling in a spot cooling manner.

  Next, when the hot air operation mode is selected, the warm air that has passed through the condenser 8 is discharged from the first air outlet 3, and the cold air that has passed through the evaporator 9 is discharged from the second air outlet 4.

  In this warm air operation mode, the laundry or the like can be dried by the warm air blown from the first air outlet 3.

  Further, when the dehumidifying operation mode is selected, the cold air that has passed through the evaporator 9, the warm air that has passed through the condenser 8, the cold air, and the warm air are discharged from the first outlet 3.

  In this dehumidifying operation mode, the indoor humidity can be controlled to an appropriate humidity.

  Here, in the warm air operation mode, the air (cold air) cooled by passing through the evaporator 9 joins the upstream side of the condenser side blowing path 20 via the bypass path 30, and therefore the condenser side blowing path 20. On the upstream side, the indoor air taken in from the first intake port 6 is cooled by the air (cold air) that has joined through the bypass path 30.

  As described above, in the warm air operation mode, the air having the temperature lower than the room temperature and the condenser 8 are subjected to heat exchange in the condenser-side air passage 20, so that the air having the room temperature and the condenser 8 exchange heat. Compared to the case, the condenser 8 can be cooled by a high cooling effect by increasing the temperature difference between the air and the condenser 8 in the condenser-side air passage 20.

  And the performance of the dehumidification part which consists of the refrigerating cycle in the dehumidifier main body 2, and the 1st and 2nd ventilation fans 10 and 12 is fully demonstrated by improving the cooling effect of the capacitor | condenser 8 in a warm air operation mode. It becomes possible to exhibit the maximum dehumidifying capacity required for quickly drying an object to be dried such as laundry.

  Therefore, in the structure of the conventional dehumidifier 101 with the cold air function as shown in FIG. 6 above, the cooling air F3 that has passed through the evaporator 102 is discharged as cold air to the outside and cannot be used for cooling the condenser 103. Compared with a conventional single-function dehumidifier that uses cooling air that has passed through the evaporator to cool the condenser, the cooling air for the condenser 103 is cooled by wind at room temperature. Although a condenser having a size about 1.5 times is required, in the dehumidifier 1 of this embodiment, in the warm air operation mode, the cooled air after passing through the evaporator 9 (arrow F1 in the figure). Part (arrow F2 in the figure) is bypassed to the condenser-side air flow path 20 upstream of the condenser 8 via the bypass path 30, so that the cooling air that has passed through the evaporator 9 is used in the same manner as in the single-function dehumidifier. Cool capacitor 8 That effect can be obtained, it is possible to miniaturize the size of the capacitor 8 as compared with the conventional cold function dehumidifier.

  This embodiment corresponds to claim 1, wherein the main body 2 of the dehumidifier 1 is provided with a first air outlet 3 and a second air outlet 4, and a condenser 8 as a condenser and an evaporator inside the main body 2. A first refrigeration cycle comprising an evaporator 9, a first blower fan 10 as an evaporator-side blowing means, a first damper 11 as an evaporator-side switching means, and a second blower as a condenser-side blowing means A fan 12 and a second damper 13 as a condenser-side switching means; an evaporator-side air passage 19 and a condenser-side air passage 20 are provided independently as air passages for the evaporator 9 and the condenser 8; Heat is exchanged with indoor air by the first and second blower fans 10 and 12, the air exchanged heat on the evaporator 9 side is cold air, and the air exchanged heat on the condenser 8 side is hot air. 2 outlets In the dehumidifier 1 that discharges from the body 2 to the outside of the main body 2, a bypass path 30 that joins the upstream side of the condenser 8 in the condenser air supply path 20 is provided on the downstream side of the evaporator 9 in the evaporator air supply path 19.

  In this case, in the warm air operation mode, which is a specific operation mode, a part F2 of the air F1 cooled by heat exchange by the evaporator 9 is upstream of the condenser 8 in the condenser side blowing path 20 via the bypass path 30. In this case, it is possible to effectively heat-exchange and cool the capacitor 8 without enlarging the size of the capacitor 8 and to secure a dehumidifying capacity. Therefore, it is possible to reduce the size and cost of the product.

  In addition, this invention is not limited to the said Example, A various deformation | transformation implementation is possible within the range of the summary of this invention. For example, the configuration of the refrigeration cycle is not particularly limited as long as it includes a condenser (condenser 8), an evaporator (evaporator 9), and a compressor. In addition, the bypass passage 30 is not limited to the configuration in which air is introduced from the evaporator-side through portion 23 to the upstream side of the condenser-side air passage 20 via the notch portion 26 of the guide plate 25. It is good also as a structure which introduces the air which passed the evaporator 9 to the upstream of the condenser side ventilation path | route 20 by tubular bodies, such as a tube which connects 23 and the upstream side of the condenser side ventilation path | route 20, and changes suitably in addition to this. Is possible.
