Description

Pet hair dryer

The present application is a divisional application of patent application of the invention with the name of "pet hair dryer" with the application of 26 months 04 in 2020 and the national application number 202010337158.3.

Technical Field

The present invention relates to a pet blower, and more particularly, to a pet blower having improved convenience in use and drying efficiency.

Background

In general, in order to keep the Pet clean, a Pet store (Pet Shop) is entrusted to bath the Pet or directly bath the Pet by itself, but if the hair is not sufficiently dried after bath, cold or skin disease may be caused.

In addition, if a general hair dryer or a pet dryer placed on a placement table is used for drying, the detached hair cannot be collected during the drying process, and a long drying time is required. In order to solve such problems, a pet blower has been developed which can receive and release a pet and blow-dry the hair.

Fig. 1 is a perspective view of a conventional pet blower.

As shown in fig. 1, a conventional pet blower includes a main body 1 having a housing space 6 for a pet therein, and a motor fan 2 provided at an upper portion of the main body 1 to transfer air in the housing space 6.

Here, a heater 3 for heating air is provided on the air passage on one side of the motor fan 2, and a dredging port 5 communicating with the air inflow passage is formed in the lower portion of the motor fan 2. Further, the pet food container is provided with a blower guide plate 4, and the blower guide plate 4 moves the air discharged from the motor fan 2 downward along the inner wall surface of the housing space 6 and then upward toward the dredging opening 5 through the periphery of the pet.

At this time, an operation panel 7 is provided on the upper side of the front surface portion of the main body 1, and the operation panel 7 includes a power switch for performing a power operation, a timer for setting operation time of the motor fan and the heater, a temperature regulator for regulating a heating temperature of air heated by the heater, and the like.

Further, a vent hole 8 is formed in a side surface portion of the main body 1, and the vent hole 8 communicates the housing space 6 with the outside, so that the housed pet breathes smoothly during the operation of the blower, and high-temperature and high-humidity air inside the housing is discharged, thereby sucking dry air outside.

That is, when the operation state is set by the operation panel 7 and started in a state where the pet is placed in the accommodating space 6, the air in the accommodating space 6 is transferred by the motor fan 2, and the pet hair is dried by the hot air as the pet hair is heated by the heater.

However, the conventional pet hair dryer naturally sucks in the dry outside air due to the structural characteristics of circulating the air in the accommodating space through the through-holes 8, and the amount of the discharged and introduced wet outside air is reduced, so that the high inside humidity is maintained, and the comfort is lowered.

In addition, the motor fan 2 sucks only air in the accommodating space 6, so that the air volume is small, a long drying time is required, and thus the drying efficiency is reduced, and the pet feels uneasy when drying for a long time.

Meanwhile, in the conventional pet blower, since the product cannot autonomously judge a malfunction at the time of the malfunction of the motor fan 2, it is difficult to rapidly cope with the malfunction, and the safety of the product is lowered.

Further, since the heater 3 is controlled to be operated for a time set by the timer, the product cannot autonomously judge whether the heater 3 is overheated or not, and thus the safety of the product is lowered.

Secondly, the exhaust fan is a bidirectional suction fan, so that the internal air and the external air are sucked simultaneously, the discharge amount is increased, and the blow-drying time is shortened, so that the blow-drying efficiency of the product is obviously improved.

Third, the exhaust fan is provided at the position 2, and the exhaust port is disposed vertically, so that a vortex is formed in the air exhausted from the upper side and the lower side to the inside of the accommodating space, thereby improving the overall circulation structure with the increase of the flow area, and further improving the drying efficiency of the product.

Fourth, the 1 st temperature sensor is provided above the heater, naturally convects when the exhaust fan or the heater fails, and rapidly determines the failure of the exhaust fan or the heater as the temperature of the upwardly moving heated air is detected in advance, thereby further improving the safety of the product.

Fifth, since the reed switch and the driving magnet for cutting off the power supply when the distance between them is equal to or greater than the predetermined distance are provided in the driving unit and the 1 st suction filter, it is possible to prevent failure of the fan, motor, etc. which occurs when the hairs, foreign matter, etc. flow into the driving unit when driving without being coupled to each other, and to further improve the safety of the product.

Sixth, the control unit turns on/off the power of the heater by the temperature detected by the 1 st temperature sensor, so that the internal temperature of the accommodating space is maintained within a certain range, thereby remarkably improving the driving stability and preventing the hair of the pet from being damaged by the high temperature air.

Seventh, since the fuse provided in the heater is rapidly disconnected when the fuse is overheated to a predetermined temperature or higher, the power supply is cut off, and thus, a fire occurring when the heater is overheated can be prevented, and the safety of the product can be remarkably improved.

Fig. 7 is a perspective view showing a coupling state of the exhaust fans in a modification of the pet blower according to the embodiment of the present invention, and fig. 8 is a sectional view showing a portion 'A-AA' of fig. 7. Meanwhile, fig. 9 is a side sectional view of a driving part in a pet blower according to an embodiment of the present invention, fig. 10 is a rear view of the driving part separating an exhaust fan of the pet blower according to an embodiment of the present invention, and fig. 11 is a graph showing temperatures detected by a 1 st temperature sensor and a 2 nd temperature sensor in the pet blower according to an embodiment of the present invention.

As shown in fig. 2a to 11, the pet blower 100 of the present invention includes a housing part 10, a driving part 60, a 1 st temperature sensor 69a, and a control unit 82.

Here, the housing 10 is preferably formed in a hexahedral shape, and a housing space 10c for housing the pet therein is formed separately from the outside. In this case, the above-described separation is preferably understood to be that the boundaries of the respective faces are separated by the outer portion and the partition wall.

An exhaust window 30 for exhausting the internal air is detachably provided on the upper surface of the housing 10, so that the internal air is exhausted upward. In this case, the discharge window 30 preferably includes a discharge filter 30b and a discharge filter cover 30a, and is disposed so as to be inserted into a cover groove 10a formed through the upper surface portion of the housing 10.

In addition, the exhaust filter 30b preferably filters foreign matters in the inside air to be exhausted. Specifically, the discharge filter 30b is preferably a dust collecting filter for fine dust formed as a mesh smaller than the diameter of fine dust, so as to filter large foreign matters adhering to the body of the pet.

Accordingly, when the pet is blow-dried, the foreign matter such as dust cannot pass through the discharge filter 30b, and only clean air is discharged to the outside, so that a high cleanliness of the external space can be maintained.

The discharge filter cover 30a is provided on the upper portion of the discharge filter 30b and is selectively attached to and detached from the upper surface portion of the housing 10. In addition, a plurality of mesh holes are preferably formed to discharge the air passing through the discharge filter 30b to the outside. In this case, the mesh holes are formed in various arrangements and shapes.

That is, when the pet blower 100 is not used, the attachment and detachment is performed to prevent foreign substances such as dust from being laminated on the discharge filter 30b, and the separated discharge filter 30b is easily cleaned, and can be re-coupled to the housing 10 when the pet blower 100 is used.

In addition, the discharge filter is removed during the use of the pet blower to treat the pet, etc., and when the hair shaft is to some extent, drying and carding can be simultaneously performed, so that a more fluffy hair state can be achieved.

In addition, the inside air having a high humidity flows upward by forced convection and is discharged upward through the discharge window 30, so that the humidity of the circulated air is lowered, and thus the drying efficiency of the product can be improved.

On the other hand, the support portion 50 is preferably inserted into the lower portion of the housing space 10c from the front in a detachable manner so as to be attached to the inner peripheral surfaces of the housing portion 10.

Specifically, the support portion 50 includes a step portion 50a formed so as to be fitted between the inner peripheral surfaces of the water collecting portions 50b and formed with a plurality of drain holes, and is separable from the water collecting portions 50 b. At this time, the water collecting portion 50b is preferably understood as a device for collecting moisture including hair or sewage of the pet discharged through the water discharge hole.

Further, a discharge hole 51 is formed in a side surface portion of the water collecting portion 50b to discharge air from the bottom surface in association with the air flow path. In this case, the drain hole 51 is preferably formed to be spaced apart from the bottom by a predetermined height so as to prevent the water and foreign matter flowing into the water collecting portion 50b from flowing out. Accordingly, the air flowing into the exhaust hole 51 is exhausted upward by the pedal portion 50a, and thus the abdomen side portion of the pet can be dried more easily.

On the other hand, the front surface of the housing 10 is opened to selectively house the pet. Specifically, it is preferable that a door 40 is detachably provided at the opening, and the door 40 includes a projection window 41 made of a transparent material, which is capable of projecting the outside inside.

Therefore, the state of the pet during blow-drying can be confirmed through the projection window 41, so that the convenience of use and the safety of the product can be improved. In addition, the pet's view is prevented from being blocked, so that the pet's sense of uneasiness can be reduced.

On the other hand, it is preferable that a windshield 20 for guiding the heated mixed air by separating the flow path from the housing space 10c is provided on both sides of the housing 10, and the windshield 20 is inserted from the rear of the housing space 10 c.

The windshield 20 preferably includes an inner surface portion 22 having an outer peripheral edge connected to the inner surface of the case portion so as to surround the flow path, and having a ventilation hole 21 formed therethrough, and an inflow port 23 provided in the rear portion.

At this time, a nozzle is provided in the air-sending hole 21 to intensively discharge the heated mixed air, and the mixed air discharged from the exhaust fan 70 is discharged to the inside through the air-sending hole 21.

The air-sending hole 21 is preferably formed in the following nozzle shape: the outer circumference is recessed, concentrated in the air discharge direction, and then protrudes toward the storage space 10c by a height corresponding to the depth of the recess. This can prevent the pet from being injured by the nozzle.

On the other hand, the rear of the housing 10 is provided with the driving unit 60 connected to the housing 10 to supply air from the rear. Specifically, the driving unit 60 is preferably understood as a device that sucks in and heats air, and discharges the air to the housing 10.

Here, the front portion of the driving portion 60 and the rear portion of the case portion 10 are coupled by a coupling means provided in a central portion, which is a space between which the windshield 20 is disposed.

Specifically, the coupling means preferably includes a hooking portion 11 provided at the rear of the housing portion 10 and a rotary lock portion 61 provided at the front of the driving portion 60, and a spring is provided in the rotary lock portion 61 to elastically support the rotary lock portion 61 to the inside of the driving portion 60.

Further, the hooking portion 11 is preferably integrally extended and projected from at least one of the upper surface and the lower surface of the rear portion side of the housing portion 10.

Specifically, the hooking hole 12 is formed to penetrate the hooking portion 11 in the front-rear direction, and an insertion long hole 13 is formed to extend in the longitudinal direction at the edge of the hooking hole 12. In this case, the insertion long hole 13 is preferably formed to be wider upward than the mounting height of the support portion 50. Here, the above-mentioned longitudinal direction is preferably understood to include not only the vertical direction but also the longitudinal direction inclined from the vertical direction.

Further, the rotation lock portion 61 is preferably integrally formed with a rotation body portion 61b having a spring therein and a rotation protrusion 61a protruding forward from an end portion of the rotation body portion 61 b.

Specifically, the rotation body portion 61b includes a spring therein to rotate the rotation protrusion 61a, and is elastically supported to the driving portion 60 side by the spring when the locking portion 61 rotates. Further, the rotation protrusion 61a is preferably formed to protrude forward, extend in the radial direction so as to correspond to the longitudinal length of the insertion long hole 13, and have a width that is formed to be received in the edge of the hooking hole 12 when rotating.

Accordingly, the rotation protrusion 61a is laterally rotated by the insertion long hole 13, thereby being received and coupled to the edge of the hooking hole 12. At this time, the locking portion 61 is elastically supported to the driving portion 60 side by a spring of the rotating body portion 61 b. Thereby, the hooking portion 11 is fixed by being abutted between the rotation protrusion 61a rotating in the lateral direction and the driving portion 60, and thereby the housing portion 10 and the driving portion 60 are stably coupled.

Thus, when the rotation locking portion 61 rotates, the rotation protrusion 61a is fixed by the rotation body portion 61b in a state of being received in the edge of the hooking hole 12, and thus the driving portion 60 and the housing portion 10 are kept in a coupled state. That is, the driving part 60 and the housing part 10 are detachably coupled by the rotation type locking part 61, so that the convenience of use of the product can be improved.

On the other hand, it is preferable that a protruding coupling partition 14 is formed at an edge of the opposite side of the driving portion 60 and the housing portion 10, and a short stage portion 62 is formed at the opposite side thereof, which is recessed stepwise so as to be in contact with the inner peripheral surface of the coupling partition 14. In this case, in one embodiment of the present invention, the short stage 62 is formed in the driving portion 60, and the coupling partition 14 is formed in the housing portion 10.

Here, it is preferable that the short stage 62 and the coupling partition 14 have sealing portions such as synthetic rubber for sealing at the connection portions between the driving portion 60 and the housing portion 10, and that the lengths of the respective sides be made to correspond to each other.

Further, the coupling partition 14 is preferably formed to have a width corresponding to the width of the short stage 62, and protrudes toward the driving unit 60. Therefore, the inner periphery of the coupling partition 14 and the outer periphery of the short stage 62 are bonded to each other in a shape-fitting manner.

The edge of the coupling partition 14 is formed in correspondence with the width of the edge of the driving portion 60, and is coupled by surface contact with each other, whereby the driving portion 60 and the housing portion 10 are coupled in a sealed state.

On the other hand, referring to fig. 3, the driving unit 60 preferably includes a heater 80 for heating air and the exhaust fan 70 for mixing the inside air and the outside air of the housing space 10c and sending the mixture to the housing unit 10.

In this case, it is preferable that a 1 st temperature sensor 69a for detecting an internal temperature is provided on one side of the driving unit 60, and a control unit 82 for applying and cutting off power to the driving unit 60 and the heater 80 is provided.

Here, the control unit 82 continuously heats the heater 80 until the internal temperature detected by the 1 st temperature sensor 69a reaches a predetermined temperature, and when the predetermined temperature is reached, the control unit 82 cuts off the power supply to the heater 80.

When the temperature detected by the 1 st temperature sensor 69a falls below a predetermined temperature, the control unit 82 restarts the heater 80. That is, the heater 80 is repeatedly operated by the control unit 82.

Accordingly, the internal temperature of the housing space 10c is kept within a certain range, and the hair of the housed pet can be prevented from being damaged by excessive heat. In addition, when the heater 80 is overheated, the control unit 82 cuts off the power, so that the safety of the product can be improved.

On the other hand, referring to fig. 4 and 5, a case where the exhaust fan 70 is 2 bi-directional fans in the pet blower according to an embodiment of the present invention is illustrated and described.

Specifically, the bidirectional suction fan preferably includes blade fans 75a and 75b and shrouds 76a and 76b having suction ports penetrating through both sides of the blade fans in the axial direction.

Accordingly, the vane fans 75a and 75b communicate with the internal air inflow windows 64 and the external air inflow windows 65 described later, and suck in the internal and external air, and the sucked air is discharged to the shrouds 76a and 76b.

Specifically, the shrouds 76a and 76b are preferably formed to extend radially outward in accordance with the shape of the vane fans 75a and 75b, and the shroud discharge port 71 for discharging air is preferably formed on one side. The bi-directional suction fan includes a 1 st bi-directional suction fan 70a communicating with the outlet on one side of the windshield 20, and a 2 nd bi-directional suction fan 70b communicating with the outlet on the other side of the windshield 20. The inside air and the outside air are mixed in a direct connection by the above-mentioned two-way suction fans 70a, 70b. In this case, the direct connection is preferably understood to be a direct connection between the inside air and the outside air in the storage space 10c without requiring an additional flow path.

Here, it is preferable that the vane fans 75a and 75b of the 1 st bidirectional suction fan 70a and the 2 nd bidirectional suction fan 70b are connected to motors independent of each other, and thereby operate independently. Accordingly, the amount of the discharged air discharged into the storage space 10c is increased, and the drying efficiency is improved.

Further, the 1 st bidirectional suction fan 70a preferably includes a 1 st shroud outlet 71a extending to one side, and the 2 nd bidirectional suction fan 70b preferably includes a 2 nd shroud outlet 71b extending to the other side.

At this time, the 1 st shield discharge port 71a and the 2 nd shield discharge port 71b are formed by being rounded and bent toward the front. Further, it is preferable that the front portion of the driving unit 60 has outlets 72 for discharging air flowing from the exhaust fan 70 on both left and right sides, and the outlets are respectively communicated with the 1 st shroud outlet 71a and the 2 nd shroud outlet 71b. Accordingly, the air discharged from the 1 st bidirectional suction fan 70a and the 2 nd bidirectional suction fan 70b flows to the discharge port 72.

In addition, the 1 st shield discharge port 71a and the 2 nd shield discharge port 71b may each include a shut-off device (not shown) for selectively shutting off the air flow. At this time, the cutting device is arranged so as to be separated across the inside of the 1 st shield discharge port 71a and the 2 nd shield discharge port 71b during cutting, and the cutting device is controlled by the control unit 82.

Specifically, when the respective cutting devices are arranged in a neutral state and air flows are opened, the air discharged from the 1 st shield discharge port 71a and the 2 nd shield discharge port 71b is discharged to the discharge ports 72 on both sides, and when the 1 st shield discharge port 71a is cut, the air is discharged only from the 2 nd shield discharge port 71 b.

The 1 st bidirectional suction fan 70a and the 2 nd bidirectional suction fan 70b are provided with a 1 st motor and a 2 nd motor, respectively, and the speed and the power supply are controlled by a control unit 82 in the 1 st motor and the 2 nd motor, respectively.

Therefore, since the air is discharged in one direction, the flow direction of the air is biased to be adjusted. Naturally, the power supply to the 2 nd motor is cut off to stop the start of the 2 nd bidirectional suction fan 70b, and only the air in the 1 st hood discharge port 71a can be made to flow.

That is, since the shut-off device and the motor are operated in parallel, when one device is erroneously operated, the remaining devices are started to control the discharge of air.

Here, the 1 st shield discharge port 71a includes the 1 st light source 68a, the 2 nd shield discharge port 71b includes the 2 nd light source 68b, and the 1 st light source 68a and the 2 nd light source 68b are selectively turned on by the control unit 82.

That is, the 1 st light source 68a and the 2 nd light source 68b are each constituted by an LED lamp, and are turned off when the 1 st shield discharge port 71a and the 2 nd shield discharge port 71b are cut off, and are turned on when the 1 st shield discharge port 71a and the 2 nd shield discharge port 71b are not cut off. Thus, the 1 st light source 68a and the 2 nd light source 68b are turned on and off, and whether the cutting device is driven or not is easily checked.

On the other hand, the 1 st light source 68a and the 2 nd light source 68b are turned on and off according to whether the 1 st bidirectional suction fan 70a and the 2 nd bidirectional suction fan 70b are operated or not, irrespective of whether the shut-off device is driven or not. That is, the 1 st bi-directional suction fan 70a and the 2 nd bi-directional suction fan 70b are selectively operated by the control unit 82, and the lamp is turned on during operation, so that whether the operation is performed or not can be easily confirmed, and thus the convenience of use can be improved.

The 1 st bidirectional suction fan 70a and the 2 nd bidirectional suction fan 70b are arranged along the vertical direction, and the discharge ports 72 are arranged so as to be offset to both sides. That is, it is preferable that the driving unit 60 is provided on both sides thereof, and that one side is positioned higher than the other side.

The 1 st bidirectional suction fan 70a and the 2 nd bidirectional suction fan 70b are preferably arranged such that the 1 st shroud discharge port 71a and the 2 nd shroud discharge port 71b communicate with the discharge ports 72 on both sides. Specifically, the exhaust port 72 is preferably formed to have an area corresponding to the shape of the 1 st shield exhaust port 71a and the 2 nd shield exhaust port 71b, so as to prevent leakage of the exhaust air.

At this time, the respective exhaust ports 72 communicate with the inflow port 23, and the exhaust air flows toward the windshield 20. Here, a protruding seal partition wall 23a is formed at one edge of the inlet 23 and the outlet 72, and a seal groove 63 that contacts the outer peripheral surface of the seal partition wall 23a is bonded to the other edge so as to communicate with each other.

The air heated by the heater 80 is discharged from the discharge ports 72 arranged in a staggered manner, and is thus discharged to the upper and lower sides of the inflow ports 23. The heated air flowing into the inflow port 23 is discharged to the accommodating space 10c through the air-sending hole 21 of the windshield 20.

Accordingly, the heated air is discharged from both sides and the lower side of the accommodating space 10c, thereby forming a vortex in the accommodating space 10c, thereby increasing a flow area, and guiding the air flowing in the interior to be entirely contacted with the pet, thereby improving the overall circulation structure and enhancing the drying efficiency of the product.

On the other hand, it is preferable that the 1 st bi-directional suction fan 70a and the 2 nd bi-directional suction fan 70b are provided with a 1 st suction port 74a and a 2 nd suction port 74b, and the inside and outside air are sucked and mixed in a direct connection. In addition, a shut-off unit (not shown) for selectively shielding the outdoor air intake is provided behind the 1 st suction port 74a and the 2 nd suction port 74b, as the case may be. Specifically, the cutting means is preferably configured to recognize whether cutting is performed by the control means 82.

Accordingly, the shut-off means (not shown) is arranged in a neutral state, and external air is sucked from the 1 st bidirectional suction fan 70a and the 2 nd bidirectional suction fan 70b when the 1 st suction port 74a and the 2 nd suction port 74b are opened. When one of the 1 st suction port 74a and the 2 nd suction port 74b is cut off, external air is sucked only from the other side.

When the cutoff means (not shown) cuts off all of the 1 st suction port 74a and the 2 nd suction port 74b, the suction of outside air is restricted, and the inside air in the storage space 10c is continuously circulated. That is, the intake amount of the outside air is adjusted by the shut-off means.

Accordingly, the temperature and humidity at the mixing point are adjusted by adjusting the ratio of the sucked external air and internal air, so that the drying efficiency of the product is improved by changing the humidity and temperature of the air discharged in accordance with the air state of the accommodating space 10 c.

On the other hand, referring to fig. 6a and 6b, an inside air inflow window 64 through which air flows from the accommodating space 10c is formed in a front surface portion of the cover forming the external appearance of the driving unit 60, and an outside air inflow window 65 through which outside air flows is formed in a rear surface portion thereof.

Here, it is preferable that the opening area of the inside air inflow window 64 communicating with the suction port 174 of the exhaust fan 170 is larger than the opening area of the outside air inflow window 65, and the opening area is adjusted by making the sizes and the arrangement of the holes penetrating through the inflow windows different.

Accordingly, in the exhaust fan 170, the amount of the heated internal air sucked by the heater 80 is larger than the amount of the normal-temperature external air sucked, and a high mixing temperature is maintained, so that the load of the heater 80 can be reduced.

On the other hand, the inside air inflow window 64 is provided with a 1 st suction filter 90a for filtering foreign matters in the inside air, and the outside air inflow window 65 is provided with a 2 nd suction filter 90b for filtering foreign matters in the outside air. In this case, it is preferable that the 1 st suction filter 90a and the 2 nd suction filter 90b are formed in a dense mesh shape to allow air to pass therethrough, but filter foreign matters such as fine dust, and form a dust collecting filter similar to the discharge filter 30 b.

Further, the heater 80 provided in the driving unit 60 is preferably disposed at a rear portion of the inside air inflow window 64. Specifically, it is preferable that the heater 80 is turned on/off by the control unit 82, and adjusts the heating temperature of the air.

Accordingly, the inside and outside air flowing into the driving unit 60 is heated to a temperature corresponding to a predetermined temperature by the heater 80, and is thereby temperature and humidity controlled, and is sucked into the exhaust fan 170 and supplied to the storage space 10c.

On the other hand, fig. 7 is a rear view showing a coupled state of the exhaust fan in a modification of the pet blower of the modification of the one embodiment of the present invention, and fig. 8 is a sectional view showing a portion 'A-AA' of fig. 7. In this case, since the basic structure of the pet blower according to the modification of the embodiment of the present invention is the same as that of the above-described embodiment, a specific description of the same structure is omitted, and the same structure is shown with the same reference numerals.

As shown in fig. 7 and 8, it is preferable that a discharge port 172 for discharging air flowing from the exhaust fan 170 is provided in a front portion of the driving unit 60, and the discharge ports 172 are arranged in a pair on both side surfaces of the front portion of the driving unit 60. Further, one side of the suction port 174 of the exhaust fan 170 communicates with the outside, and the other side communicates with the accommodating space 10c, thereby bidirectionally sucking air.

That is, the exhaust fan 170 is preferably configured as a two-way fan that directly mixes the inside air and the outside air of the accommodating space 10c by communicating both sides of the suction port 174 with the inside and the outside of the accommodating space 10c, respectively.

Therefore, the exhaust fan 170 is formed of a bi-directional suction fan to mix the inside air and the outside air in a direct connection manner, thereby forcibly sucking the outside blow-drying air, and thus the forced discharge amount of the inside air having a high humidity is increased, thereby improving the blow-drying efficiency of the product.

Specifically, the exhaust fan 170 preferably includes a vane fan 175 and a shroud 176 having suction ports penetrating both sides of the vane fan 175 in the axial direction. Accordingly, the air sucked from the vane fan 175 is discharged to the shroud 176.

Further, the shroud 176 is preferably formed to extend radially outward in accordance with the shape of the vane fan 175, and a shroud discharge port 171 for discharging air is preferably formed at one side.

Further, the shroud discharge port 171 is preferably branched to both sides and connected to the respective discharge ports 172, and the shroud discharge port 171 is preferably formed to be rounded and bent toward the front. Accordingly, the air discharged from the exhaust fan 170 flows through the shroud discharge port 171 to the discharge port 172.

Further, the branched shield discharge ports 171 are provided with a cutting device 173 for selectively cutting off the shield discharge ports 171. At this time, the cutting device 173 is driven by a motor controlled by the control unit 82.

Specifically, when the cutting device 173 is arranged in a neutral state, air is discharged in both directions from the respective shield discharge ports 171, and when the shield discharge port 171 on one side is cut off, air is discharged in one direction, so that the flow direction of air can be adjusted.

Here, the 1 st light source 68a is provided at one discharge port of the shield 176, the 2 nd light source 68b is provided at the other discharge port, and the 1 st light source 68a and the 2 nd light source 68b are selectively turned on according to whether or not both sides of the shield discharge port 171 are cut off.

That is, the 1 st light source 68a and the 2 nd light source 68b are LED lamps, respectively, which are turned off when the shield discharge port 171 is cut off, and are turned on when the shield discharge port 171 is not cut off, so that whether the cutting device 173 is driven or not can be easily confirmed.

Referring back to fig. 4 and 5, the driving unit 60 preferably includes a cover having an inner air inflow window (64 in fig. 6 a) for flowing air from the storage space 10c in a front surface portion and forming an external appearance, a heater 80 provided behind the inner air inflow window (64 in fig. 6 a), and an exhaust fan 70 for exhausting air heated by the heater 80, and the inner air inflow window 64 preferably includes a 1 st suction filter 90a for filtering foreign matters in the inner air, and the outer air inflow window 65 includes a 2 nd suction filter 90b for filtering foreign matters in the outer air. In this case, the 1 st suction filter 90a and the 2 nd suction filter 90b are preferably formed in a dense mesh shape to allow air to pass therethrough and filter foreign substances such as fine dust, and are formed as dust collecting filters similar to the discharge filter 30 b.

In this case, it is preferable that the 1 st suction filter 90a includes a driving magnet 91, and that the driving unit 60 includes reed switches 66 disposed at predetermined intervals at positions corresponding to the driving magnet 91.

That is, when the reed switch 66 turns on/off the contact according to the change in the distance from the driving magnet 91 and the change in the distance between the reed switch 66 and the driving magnet 91 is equal to or more than a predetermined interval, the control unit 82 turns off the power supply to the driving unit 60.

Therefore, if the 1 st suction filter 90a and the driving unit 60 are not properly coupled, a failure of the fan, motor, or the like, which is caused by the flow of the hair, foreign matter, or the like into the driving unit 60, can be prevented, and the safety of the product can be further improved.

Further, the heater 80 is preferably provided in the driving unit 60 and disposed at a rear portion of the 1 st suction filter 90 a. Specifically, it is preferable that the heater 80 is turned on/off by the control unit 82, and adjusts the heating temperature of the air.

Here, a wiring board 67 is provided on the left inner wall of the driving unit 60 to control the power supply to the heater 80, the motor, and the like. Specifically, the wiring board 67 is preferably understood as a device to which a substrate for supplying power to the heater 80, the motor, and the like is connected under the control of the control unit 82. Of course, the wiring board 67 is provided in the internal space of the driving section such as the right inner wall, as the case may be.

On the other hand, referring to fig. 10 and 11, the driving unit 60 preferably includes a 1 st temperature sensor 69a disposed apart from the heater 80, and the 1 st temperature sensor 69a is disposed on an upper side facing an upper surface portion of the heater 80.

The driving unit 60 includes the control unit 82 for controlling the power supply to be turned off based on the temperature detected by the 1 st temperature sensor 69 a. At this time, when the temperature detected by the 1 st temperature sensor 69a is equal to or higher than a predetermined temperature, the control unit 82 controls a power supply device coupled to the wiring board 67 to cut off the power supply to the heater 80.

That is, the heater 80 continuously generates heat until the internal temperature detected by the 1 st temperature sensor 69a reaches a preset temperature. When the temperature detected by the 1 st temperature sensor 69a reaches a predetermined temperature, the control unit 82 turns off the power supply to the heater 80.

In addition, when the temperature detected by the 1 st temperature sensor 69a falls below a preset temperature, the control unit 82 restarts the heater 80. That is, the heater 80 is repeatedly operated by the control unit 82.

Accordingly, as the internal temperature of the housing space 10c is maintained within a certain range, the hair of the housed pet is prevented from being damaged due to excessive heat. In addition, when the heater 80 is overheated, the control unit 82 cuts off the power supply, thereby improving the safety of the product.

On the other hand, the driving unit 60 further includes a 2 nd temperature sensor 69b for detecting the internal temperature of the storage space 10 c. Specifically, the 2 nd temperature sensor 69b is preferably provided on one side of the driving unit 60 and is located at a position contacting the inside air to detect the temperature of the inside air.

Therefore, since the air is not discharged when the exhaust fan 70 is not operated, the forced flow is reduced in the storage space 10c, and the air naturally flows, so that the heated air flows upward. Therefore, the change in the 2 nd temperature s2 detected by the 2 nd temperature sensor 69b provided on one side is slow.

The 1 st temperature sensor 69a is provided above the heater 80, and the 1 st temperature s1 detected by the 1 st temperature sensor 69a rises in a short time by the upward flow of the air heated by the heater 80. Therefore, the 1 st temperature sensor 69a detects a temperature change of the inside air in advance.

That is, the difference between the temperatures detected by the 1 st temperature sensor 69a and the 2 nd temperature sensor 69b increases with the passage of time, and thus, if the difference in temperature is equal to or greater than a preset safety allowable value, a failure of the exhaust fan 70 can be determined. Therefore, when the difference in temperature is equal to or greater than a preset safety allowable value, the control unit 82 cuts off the power supply to the driving unit 60, thereby preventing malfunction of the product.

In this way, since the failure of the exhaust fan 70 can be rapidly determined by the 1 st temperature sensor 69a, the fire occurring when the exhaust fan 70 fails can be prevented, and the safety of the product can be improved.

Since the forced flow occurs in the housing space 10c during the normal operation of the exhaust fan 70, the temperature difference between the 1 st temperature s1 detected by the 1 st temperature sensor 69a and the 2 nd temperature s2 detected by the 2 nd temperature sensor 69b is within a range of a safety allowable value.

The heater 80 further includes an overheat protection fuse 81 that opens when the cut-off temperature is equal to or higher than a predetermined cut-off temperature. Specifically, the fuse 81 determines whether the heater 80 is overheated or not, and thus is rapidly opened to cut off the power when the heater 80 is overheated, thereby improving the safety of the product.

Meanwhile, the driving unit 60 further includes a dust sensor 92 for detecting dust in the storage space 10 c. Therefore, the dust sensor 92 detects the cleanliness of the air and transmits a signal to the control unit 82. At this time, the control unit 82 controls the 1 st light source 68a or the 2 nd light source 68b to be lighted in different colors based on the cleanliness, thereby indicating the cleanliness. That is, the color turns blue in a state where the cleanliness is good, and turns red in a state where the cleanliness is poor. Thus, the user can recognize the air cleanliness of the inside of the accommodating space 10c during the drying of the pet.

The driving unit 60 further includes an ion generator 93 for generating anions. Thus, anions are mixed to supply clean air to the pet when the air is discharged into the storage space 10 c.

On the other hand, in fig. 2a and 2b, the side wall 10b of the housing 10 is illustrated as being divided to show the inside of the housing space, but the housing 10 and the side wall 10b may be integrally formed.

In this case, unless otherwise noted, the terms "including", "comprising", "having" or "with" and the like in the above description mean that the corresponding constituent elements may be incorporated, and therefore, other constituent elements are not excluded, but may be included. Unless otherwise defined, all terms including technical or scientific terms have the same meaning as commonly understood by one of ordinary skill in the art. The term commonly used as a term defined in a dictionary should be interpreted as meaning matching the meaning of the related art article, and should not be interpreted as meaning of abnormality or excessive form in the case where it is not explicitly defined in the present invention.

As described above, the present invention is not limited to the above-described respective embodiments, and those skilled in the art can implement modifications without departing from the scope of the invention as claimed in the claims, and such modifications belong to the scope of the present invention.
