At this time, the number or shape of the first and second support protrusions 1151 and 1152 is not particularly limited as long as they can support the evaporator 110 and the condenser 120, respectively, but they are introduced through the suction duct 151 The first and second support protrusions 1151 and 1152 so that condensed water generated in the heat exchanger can flow to the downstream end of the heat exchanger housing 115 along the bottom surface 115b of the inclined heat exchanger housing 115. may have an opening (not shown) for securing a flow path.

As described above, the bottom surface of the heat exchanger housing 115 may be inclined so that its height decreases toward the other end, that is, the downstream end (refer to FIG. 6 ). Assuming that the upper surface of the heat exchanger housing 115 having a rectangular cross section is parallel to the horizontal line, the bottom surface of the heat exchanger housing 115 may be formed to be an inclined surface inclined at a predetermined angle to the horizontal line.

Figure 7a is a view showing an intermediate duct according to an embodiment of the present invention.

As shown in FIG. 7A , the intermediate duct 152 may have a shorter length than the heat exchanger housing 115 , but may decrease the direction of the airflow passing through the heat exchanger housing 115 . That is, the height of the intermediate duct inlet 152a formed at one end of the intermediate duct 152 and the height of the intermediate duct outlet 152b formed at the other end of the intermediate duct 152 may be different from each other.

As shown in Fig. 8 showing the longitudinal view of Fig. 7a, comparing the intermediate height C1 of the intermediate duct inlet 152a with the opening and the intermediate height C2 of the intermediate duct outlet 152b with the opening, the intermediate duct The intermediate height C1 of the inlet 152a may be formed higher by Δh than the intermediate height C2 of the intermediate duct outlet 152b.

Accordingly, the air introduced into the intermediate duct 152 through the intermediate duct inlet 152a can be guided downward so that the air is discharged through the intermediate duct outlet 152b located below the intermediate duct inlet 152a.

However, even if the air flow passing through the intermediate duct 152 is directed downward, in order not to significantly affect the flow rate and/or flow rate of the entire circulation air passage 101, the intermediate duct inlet 152a and the intermediate duct outlet 152b ) is preferably formed so that a portion is overlapped with each other facing each other.

To this end, the coupling frame 172 may be provided with a water-blocking plate 173 at the inner lower end portion to block the condensed water from flowing in through the intermediate duct inlet 152a.

In the heat pump device 100 according to an embodiment of the present invention, since the fan 105 is provided at the downstream end rather than the upstream end of the airflow, the condensed water stored on the bottom of the heat exchanger housing 115 is located at the rear end. There is a problem in that air may be introduced into the intermediate duct 152 and the fan 105 together with the air by the negative pressure formed by the driving of the fan 105 .

When condensed water flows into the fan 105 in this way, noise and odor may be generated by the operation of the fan 105, and furthermore, the condensed water may be discharged into the laundry treatment chamber 11 through the air outlet 12b. It is preferable that the water blocking plate 173 blocks the condensed water from flowing into the intermediate duct 152 and the fan 105 .

9 is a view for explaining the function of the water splash prevention cover according to an embodiment of the present invention.

As shown in Figure 9, the inner lower end of the coupling frame 172 formed along the edge of the intermediate duct inlet 152a is provided with an order plate 173 of a predetermined height, and is stored on the bottom surface of the heat exchanger housing 115. It is possible to block the condensed water from splashing or flowing into the intermediate duct 152 and the fan 105 .

However, in order to prevent the airflow from being blocked together by the water-blocking plate 173, the water-blocking plate 173 preferably has a mesh shape perforated to a predetermined size. That is, the water blocking plate 173 according to this has a function to block condensed water, but it is good to have air permeability.

The hole perforated in the water-blocking plate 173 according to the present invention is not particularly limited in shape, size, or number.

On the other hand, the other end of the intermediate duct 152 may be connected to a fan 105 for generating an air flow, specifically, the intake port 160a to be able to communicate. Hereinafter, reference numerals 105 and 160 indicating a fan will be used interchangeably.

10 and 11 are views showing the external appearance of a fan according to an embodiment of the present invention, FIG. 12 is a longitudinal cross-sectional view of a fan according to an embodiment of the present invention, and FIGS. 13A and 13B are views showing an embodiment of the present invention It is a view for explaining the air flow path of the fan.

10 to 13B, the fan 160 according to an embodiment of the present invention may be a centrifugal fan. Specifically, the fan 160 according to an embodiment of the present invention includes a fan housing 161 provided with an intake port 160a and an exhaust port 160b, a rotation shaft 165 provided in the intake port 160a, and a rotation shaft 165 from It may include a plurality of blades 166 elongated in the axial direction provided to be rotatably spaced apart by a predetermined distance around the rotation shaft 165 .

At this time, the plurality of blades 166 may have a curved shape to be inclined in any one rotational direction of the rotation shaft 165 , and the length of the wing string may be short and the width of the blade may be wide.

The plurality of blades 166 rotate around the rotating shaft 165 so that centrifugal force acts on the air introduced in the axial direction of the rotating shaft 165 through the intake port 160a, so that the air introduced by the centrifugal force is rotated through the rotating shaft. It is discharged in the radial direction of 165 , and by flowing along the inner surface (or inner circumferential surface) of the fan housing 161 , it may be exhausted through the exhaust port 160b.

The driving shaft of the driving device 167, such as a motor, is coupled to the rotating shaft 165 through the driving shaft insertion hole 161a of the fan 160, and thereby the rotating shaft 165 and a plurality of blades ( 166 rotates about the rotation shaft 165, and discharges the air introduced through the intake port 160a provided on the front surface of the rotation shaft 165 in the radial direction of the rotation shaft 165, and on the upper part of the fan housing 161 It can be discharged through the opening formed exhaust port (160b).

Here, the fan housing 161 has a substantially flat disk shape, in which case the rotation shaft 165 may be provided to be eccentric in the direction toward the front of the fan housing 161 , that is, the intermediate duct 152 . That is, the rotation shaft 165 is eccentric so that the flow path width of the air flowing in the fan housing 161 is gradually widened by the rotation of the rotation shaft 165, and the air subjected to centrifugal force rotates along the inner circumferential surface of the fan housing 161 while The speed may be gradually reduced, and accordingly, the flow rate (or air volume) of the air discharged through the exhaust port 160b may be increased, and noise and vibration may be reduced at the same time.

Here, the fan housing 161 ensures that the open area of the exhaust port 160b provided at the top is wide, and the air flowing in from the front intake port 160a is rotated along the inner circumferential surface of the fan housing 161, The inner wall of the fan housing 161 may include a vortex guide plate 1611 inclined so that the width of the airflow becomes narrower from the distal end of the exhaust port 160b toward the upstream side.

As a result, as shown in FIGS. 13A and 13B , the cross-sectional area opened of the exhaust port 160b at the lower end of the inclined vortex guide plate 1611 may gradually become wider toward the upper side of the vortex guide plate 1611 .

Meanwhile, the fan housing 161 according to an embodiment of the present invention may include a condensed water accommodating chamber 162 having a predetermined space 1621 at a lower portion in which condensed water can be accommodated.

The condensed water accommodating chamber 162 may have a separate space in addition to the internal space of the fan housing 161 to store condensed water. The condensed water accommodating chamber 162 may be provided under the fan housing 161, and accordingly, the lower portion of the fan housing 161 has a generally rounded appearance to rotate the air subjected to centrifugal force, A portion of the box-shaped condensate accommodating chamber 162 for storing water may be formed to protrude.

In addition, a condensate receiving chamber 162 is provided at a lower portion of the fan housing 161, and an exhaust port 160b is provided at an upper portion of the fan housing 161 opposite to the fan housing 161, so that the air outlet 12b of the laundry treatment chamber 11 is provided. When condensed water flows into the clothes treatment chamber 11 from the can do. Of course, condensed water formed from moisture in the air may be stored in the condensed water storage space 1621 while the refrigerant exchanges heat with air by driving the heat pump device 100 .

As shown in FIG. 13b , the condensed water stored in the condensate accommodating chamber 162 is naturally evaporated and removed by the air flowing along the second and third flow paths f2 and f3 by driving the fan 160 . can be The air sucked in through the intake port 160a is heated and dehumidified air, and flows through the condensate accommodating chamber 162 along the second and third flow paths f2 and f3 to be stored in the condensate accommodating chamber 162. Condensate may evaporate spontaneously.

Specifically, the air introduced through the intake port 160a along the rotation shaft 165 is discharged in the radial direction of the rotation shaft 165, rotates along the inner surface of the fan housing 161, and then is exhausted to the exhaust port 160b. A flow path f1 may be formed.

The air flowing along the first flow path f1 at high pressure and high speed in the fan housing 161 maintains the pressure and speed even though the condensate accommodating chamber 162 is additionally provided at the bottom, and a part of the condensate accommodating chamber is provided. In order to branch into the condensate water storage space 1621 of the 162 , the upper portion of the condensate receiving chamber 162 may further include a rounded branch plate 1612 .

The branch plate 1612 covers the upper opening surface of the condensate accommodating chamber 162, has a convex rounded shape downward, and rotates along the first flow path f1 of the inner surface of the condensate accommodating chamber 162. It is preferable to guide the flow direction so that it can continuously move without changing the airflow regardless of the existence of the condensate accommodating chamber 162 .

Accordingly, condensed water may be stored on the upper surface of the branch plate 1612 for reasons such as falling through the exhaust port 160b, and the condensed water stored on the upper surface of the branch plate 1612 flows along the first flow path f1. It can be spontaneously evaporated by air.

That is, the branch plate 1612 according to an embodiment of the present invention provides another space in which condensed water can be stored in addition to the condensate receiving chamber 162, and the collected condensate flows along the first flow path f1. It can be allowed to evaporate naturally by air.

On the other hand, the branch plate 1612 is spaced apart from each other in the upper part of the condensate accommodating chamber 162 in a thin plate shape, so that at each upper end of both sides of the condensate accommodating chamber 162, the branch plate 1612 is spaced apart from each other. An inlet 162a and a branch outlet 162b may be formed (see FIG. 13A ). In other words, each of the upstream and downstream ends of the branch plate 1612 with respect to the first flow path f1 is spaced apart from the lower inner surface of the fan housing 161, so that the branch inlet 162a and the branch outlet 162b are spaced apart from each other. can be formed.

Accordingly, the air flowing at high pressure and high speed along the first flow path f1 faces one end of the branch plate 1612, and a part of it is branched through the branch inlet 162a to the condensate receiving chamber 162. can be introduced into

At this time, both end portions of the branch plate 1612 have a tapered shape such that the thickness becomes thinner toward the distal end, so that some of the air flowing along the first flow passage f1 branches to the second flow passage f2. Air resistance is lowered, and at the same time, the upper surface of the branch plate 1612 forms a natural continuous surface with the inner surface of the fan housing 161 at each of both end portions, so that the main air flow of the first flow path f1 direction may not be changed. That is, the branch inlet 162a is formed to have a narrow width, so that the influence on the flow of air flowing along the first flow path f1 can be minimized.

Specifically, the width of the second flow path f2 passing through the branch inlet 162a is formed to be relatively narrower than the width of the first flow path f1, and the condensate is introduced into the condensate receiving chamber 162 through the branch inlet 162a. It is preferable to allow the air to be stored in the condensate receiving chamber 162 without being discharged to the branch outlet 162b by force.

As a result, the air branched from the first flow path f1 at the upstream end of the branch plate 1612 forms a second flow path f2 introduced into the condensate receiving chamber 162 through the branch inlet 162a, but the second The flow velocity of the air flowing along the flow path f2 is relatively slower than the flow velocity of the air flowing along the first flow path f1, and the heated and dehumidified air flows along the second flow path f2 in the condensate accommodating chamber 162. can be supplied with

The air in the condensate accommodating chamber 162 may be sucked through the branch outlet 162b by the air flowing at high speed along the first flow path f1 at the downstream end of the branch plate 1612, and accordingly Three flow paths f3 may be formed. That is, the air in the condensate accommodating chamber 162 is sucked into the first flow path f1 by the negative pressure formed around the branch outlet 162 , so that the third flow path f3 may be formed.

On the other hand, centering on the condensate accommodating chamber 162, the second flow path f2 formed by the air introduced through the branch inlet 162a, and the third flow path f2 formed by the air discharged through the branch outlet 162b. When the flow path f3 is branched or merged from the main flow path f1, in order to maintain the direction of the rotating air flow and smooth the flow of air, the bottom surface of the condensate accommodating chamber 162 is provided with It may include a plurality of second guide blades 1622 protruding along the flow direction of the second and third flow paths f2 and f3 to be guided (see FIG. 12 ).

In addition, the branch plate 1612 may include a plurality of first guide blades 1613 to be protruded along the longitudinal direction on the upper surface to induce the flow of air (see FIG. 12 ). At this time, the present invention is not particularly limited, but as shown in FIG. 12 , the length of the first guide wing 1613 may be shorter than the length of the branch plate 1612 .

The first and second guide blades 1613 and 1622 may be in the form of a plurality of plates elongated in the same direction on the upper surface of the branch plate 1612 and the lower surface of the condensate receiving chamber 162, respectively, and the first and second guides The blades 1613 and 1622 may align the flow of air flowing along the first and second guide blades 1613 and 1622 to facilitate the flow of air flowing in the rotational direction within the fan housing 161 . .

Meanwhile, the fan 160 according to an embodiment of the present invention may include at least one choking prevention device 163 and 164 in the fan housing 161 .

11 and the like, at least one anti-suffocation device (163, 164) is provided on the front, rear, and/or any one side of the fan 160, the external airway formed by the asphyxiation device (163, 164) The outside air introduced through the inlets 163a and 164a flows into the fan housing 161, and sequentially passes through the exhaust port 160b, the exhaust duct 153, and the air outlet 12b, and into the laundry treatment chamber 11. can be provided.

Preferably, as described later, the suffocation prevention devices 163 and 164 are provided on one side of the fan housing 161, and are provided on the airflow rising toward the exhaust port 160b of the first flow path f1. good night.

In general, since the inside of the laundry treatment room 11 with the door 40 closed is sealed, when a child or a companion animal is trapped inside the laundry treatment room 11, the carbon dioxide concentration in the narrow laundry treatment room 11 increases, resulting in insufficient oxygen, etc. There is a risk that an accident may occur.

Therefore, in order to solve this problem, as a way to provide outside air to the inside of the laundry treatment room 11, the fan housing 161 of the fan 160 according to an embodiment of the present invention is a suffocation prevention device. (163, 164).

14 is a longitudinal cross-sectional view of a suffocation prevention device according to an embodiment of the present invention.

As shown in FIG. 14 , the choking prevention devices 163 and 164 may be provided in an opening in which a partial area of the fan housing 161 is formed. The suffocation prevention devices 163 and 164 of sizes corresponding to the openings are provided, so that outside air can be introduced into the fan housing 161 , but the air flowing inside the fan housing 161 is outside the fan housing 161 . can be prevented from being emitted.

Accordingly, the suffocation prevention devices 163 and 164 are provided with the external introduction plates 1631 and 1641 and the external intake covers 1632 and 1642 to block the openings from the outside and the inside respectively with the opening of the fan housing 161 as the center. may include

Specifically, each of the outside introduction plates 1631 and 1641 and the outside introduction covers 1632 and 1642 is formed to extend upward from the lower end of the opening of the fan housing 161 to block the front and rear surfaces of the opening, but at this time, outside introduction The upper ends of the plates 1631 and 1641 and the outside air introduction covers 1632 and 1642 are free ends and are spaced apart from the fan housing 161 by a predetermined distance to form a gap through which outside air can be introduced into the fan housing 161. It is preferable to do

External air may be introduced into the fan housing 161 through the external airway inlet (163a, 164a) formed accordingly. That is, outside air is introduced into the gap between the upper ends of the fan housing 161 and the outside introduction plates 1631 and 1641 , and the introduced outside air is introduced into the fan housing 161 and the outside air through the opening of the fan housing 161 . It may be introduced into the fan housing 161 through a gap between the upper ends of the covers 1632 and 1642 .

Here, the present invention is not particularly limited, but the lower end corners of the fan housing 161 and/or the upper end corners of the outdoor air introduction plates 1631 and 1641 forming a gap through which the outside air is introduced are obliquely formed, so that along the oblique slope It is preferable to guide the outside air introduced from the outside to the inside so that it can be introduced downward.

By the air flowing at high speed inside the fan housing 161, that is, the air flowing at high speed along the main flow path f1, the outside air introduced into the external airway inlets 163a and 164a is sucked and the first It may be joined to the flow path f1. In other words, the air flowing at high speed along the first flow path f1, specifically along the inner and outer surfaces of the outside air introduction covers 1632 and 1642, generates a positive pressure higher than the atmospheric pressure outside the fan housing 161, and accordingly A relatively negative pressure is formed around the upper ends of the external inlet covers 1632 and 1642, and the air introduced into the external inlets 163a and 164a by the formed negative pressure may be sucked into the fan housing 161.

Here, the outside air introduction covers 1632 and 1642 provided inside the fan housing 161 have a streamlined appearance, so that the air flowing along the first flow path f1 passes the inner outer surfaces of the outside air introduction covers 1632 and 1642. It is preferable to minimize the air resistance of the airflow by the outside inlet covers 1632 and 1642 when flowing along.

Specifically, the outside air introduction covers 1632 and 1642 may have an outer surface convex in the inner direction of the fan housing 161 at a predetermined height, and the upper and lower ends of the outside air introduction covers 1632 and 1642 around the convex portion. Doedoe is formed concave toward the outside, the upper end of the outside air introduction cover (1632, 1642) into which the outside air is introduced may have a sharp appearance, the thickness may gradually decrease toward the distal end.

The air flowing along the first flow path (f1) rides on the inner outer surface of the streamlined external inlet cover (1632, 1642) and flows upward at high speed, through the external inlet (163a, 164a), the external inlet cover (1632, 1642) can be sucked in the outside air introduced to the outer surface.

On the other hand, it is preferable to form the upper end height (h1) of the outside inlet cover (1632, 1642) higher than the upper end height (h2) of the outdoor introduction plate (1631, 1641). This is to prevent the air flowing upward of the external inlet covers 1632 and 1642 along the first flow path f1 from being discharged to the outside through the external inlet inlets 163a and 164a.

In addition, as described above, there may be condensed water inside the fan housing 161 for various reasons, and the condensed water flowing down along the inner wall of the fan housing 161 is spaced apart from the outside air intake covers 1632 and 1642. By falling into the gap formed between the ends, water can be stored between the outside introduction plates (1631, 1641) and the outside introduction cover (1632, 1642).

Since the condensed water stored between the outside introduction plates 1631 and 1641 and the outside introduction covers 1632 and 1642 does not come into contact with the air flowing inside the fan housing 161 and cannot be evaporated naturally, the outside introduction plates 1631, 1641) and the outside inlet cover (1632, 1642) as a way to remove the stored condensate, the fan housing (161) through the drain hole (1644) formed in the outside introduction cover (1632, 1642), specifically, condensed water It can be guided to the accommodation chamber (162).

As shown in FIG. 15 , the outside introduction covers 1632 and 1642 may include a drain hole 1644 perforated at the lower end, preferably at one end of the lower end.

Accordingly, the condensed water stored between the outdoor intake plates 1631 and 1641 and the outdoor intake covers 1632 and 1642 flows into the fan housing 161 through the drain hole 1644, and the inner wall of the round fan housing 161. can be stored in the condensed water storage space 1621 of the condensed water storage chamber 162, and the condensed water stored in the condensed water storage space 1621 is in the air flowing along the second and third flow paths f2 and f3. may be spontaneously evaporated.

On the other hand, in order to guide the condensed water stored between the outdoor inlet plates 1631 and 1641 and the outdoor inlet covers 1632 and 1642 to the drain 1644, the suffocation prevention devices 163 and 164 are provided in the fan housing 161. The bottom of the opening of the slit may have an inclined surface t2 that is formed to decrease in height toward the drain 1644 (refer to FIG. 16 ).

Of course, corresponding to the bottom surface of the opening of the fan housing 161, the outdoor intake covers 1632 and 1642 having a drain port 1644 are also inclined so that the lower end t3 is lowered in height toward the drain port 1644. may have a form.
