Description

Pet hair drier

The application is a divisional application of an invention patent application with the filing date of 26/04 in 2020, the national application number of 202010337158.3 and the title of "pet hair dryer".

Technical Field

The present invention relates to a pet hair dryer, and more particularly, to a pet hair dryer which improves convenience of use and drying efficiency.

Background

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

In addition, if a general hair dryer or a pet dryer placed on a placing table is used for drying, fallen hairs cannot be collected during the drying process, and a long drying time is required. In order to solve such problems, pet hair dryers have been developed which can collect and blow the pet hair.

Fig. 1 is a perspective view of a conventional pet hair dryer.

As shown in fig. 1, a conventional pet hair dryer includes a main body 1 having a pet storage space 6 therein, and a motor fan 2 provided above the main body 1 to transfer air in the storage space 6.

Here, a heater 3 for heating air is provided on one side of the motor fan 2 on an air transfer path, and a dredging port 5 communicating with an air inflow path is formed at a lower portion of the motor fan 2. Further, the pet air cleaner is provided with an air supply guide panel 4, and the air supply guide panel 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 ventilation opening 5 through the periphery of the pet.

In this case, 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 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 ventilation hole 8 is formed in the side surface of the main body 1, and the ventilation hole 8 communicates the housing space 6 with the outside, so that the housed pet can smoothly breathe during the operation of the blower, and high-temperature and humid air inside the housing can be discharged and dry air outside the housing can be sucked.

That is, when the operation state is set by the operation panel 7 and the pet is started in a state where the pet is put in the housing space 6, the air in the housing space 6 is transferred by the motor fan 2 and the pet hair is hot-air dried by heating by the heater.

However, in the conventional pet hair dryer, dry outside air is naturally sucked through the through holes 8 due to the structural characteristic of circulating air in the housing space, and thus the amount of discharged humid inside air and the amount of introduced dry outside air are reduced, so that high inside humidity is maintained, and comfort is lowered.

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

Meanwhile, in the conventional pet hair dryer, since a product cannot autonomously determine a failure when the motor fan 2 malfunctions, it is difficult to quickly respond thereto, and the safety of the product is lowered.

In addition, since the heater 3 is controlled to operate for the time set by the timer, the product cannot autonomously determine whether the heater 3 is overheated or not, which results in a reduction in the safety of the product.

Problems to be solved by the invention

In order to solve the above-mentioned problems, an object of the present invention is to provide a pet hair dryer which improves safety and drying efficiency.

Means for solving the problems

In order to solve the above problems, the present invention provides a pet hair dryer, comprising: a housing part which is formed with a housing space separately from the outside, the housing space housing a pet therein; and a driving part for supplying the heated mixed air to the accommodating space side, the driving part comprising: a heater that heats air; and a fan for mixing the internal air and the external air in the accommodating space and sending the mixed air to the shell side.

Meanwhile, the present invention provides a pet hair dryer, comprising: a housing part which forms a housing space separately from the outside, the housing space housing a pet therein; a drive section including: a cover which is provided with an internal air inflow window for air to flow from the accommodating space on the front face part and forms an appearance; a heater disposed behind the internal air inflow window; an exhaust fan for sending out the air heated by the heater; a 1 st temperature sensor separately disposed above the heater; and a control unit for controlling the power supply to be disconnected according to the temperature detected by the 1 st temperature sensor.

Effects of the invention

The present invention provides the following effects by the above-described solution.

First, the exhaust fan forcibly sucks the outside blow-dry air, so that the forcibly discharged amount of the inside air having a high humidity is increased, and the humidity of the circulated air is decreased, thereby improving the comfort of the product, reducing the blow-dry time, and further improving the blow-dry efficiency of the product.

Second, the exhaust fan is a bidirectional suction fan to simultaneously suck in the inside air and the outside air, thereby increasing a discharge amount, and thus reducing a drying time to remarkably improve a drying efficiency of a product.

Thirdly, the exhaust fan is arranged at the position 2, and the exhaust port is arranged up and down, so that a vortex is formed in the air exhausted from the upper side and the lower side to the inner part of the accommodating space, thereby improving the whole circulation structure along with the increase of the flow area, and further improving the drying efficiency of the product.

Fourthly, the 1 st temperature sensor is installed on the upper side of the heater, and natural convection is performed when the exhaust fan or the heater is out of order, and the temperature of the heated air moving upward is detected in advance, so that the failure of the exhaust fan or the heater is rapidly determined, 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 more than the predetermined interval are provided in the driving unit and the 1 st suction filter, it is possible to prevent a malfunction of the fan, the motor, or the like, which may occur when hairs, foreign substances, or the like flow into the driving unit when the driving unit is driven in a state where they are not coupled to each other, thereby further improving the safety of the product.

Sixthly, the control unit turns on/off the heater according to 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 driving stability and preventing the pet hair from being damaged by high-temperature air.

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

Meanwhile, fig. 9 is a side sectional view of a driving part in a pet hair dryer according to an embodiment of the present invention, fig. 10 is a rear view of a driving part in which a discharge fan is separated in the pet hair dryer 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 hair dryer 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 10, a driving part 60, a 1 st temperature sensor 69a, and a control unit 82.

Here, the housing portion 10 is preferably formed in a hexahedral shape, and is formed as a housing space 10c for housing a pet therein separately from the outside. In this case, the division is preferably understood as a separation in which boundaries of the respective surfaces are separated by partitions and the outside.

In addition, a discharge window 30 for discharging the internal air is detachably provided on the upper surface of the case 10, and the internal air is discharged upward. In this case, the discharge window 30 preferably includes a discharge filter 30b and a discharge filter cover 30a, and is inserted into a cover groove 10a formed through the upper surface portion of the case portion 10.

In addition, the discharge filter 30b preferably filters foreign matters in the interior air discharged upward. Specifically, it is preferable that the discharge filter 30b is a dust collecting filter for fine dust formed into a mesh smaller than the diameter of fine dust to filter large foreign matters to fine dust stuck to the body of the pet.

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

The discharge filter cover 30a is provided above the discharge filter 30b and selectively attached to and detached from the upper surface of the housing 10. In addition, it is preferable that a plurality of mesh holes are formed to discharge the air passing through the discharge filter 30b to the outside. In this case, the mesh holes are formed in various arrangement structures and shapes.

That is, the pet hair dryer 100 is attached and detached when not in use, so that foreign matter such as dust is prevented from being stacked on the discharge filter 30b, the separated discharge filter 30b is easily cleaned, and the pet hair dryer 100 can be re-coupled to the housing 10 when in use.

In addition, the exhaust filter is removed to give pet snacks and the like in the process of using the pet dryer, and when the hair shaft reaches a certain degree, the drying and combing can be simultaneously performed, so that a more fluffy hair state can be realized.

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

On the other hand, it is preferable that the support portion 50 is detachably inserted from the front into the lower portion of the housing space 10c so as to be fitted between the inner circumferential surfaces of both sides of the housing portion 10.

Specifically, the support portion 50 includes a step portion 50a formed to fit between the inner circumferential surfaces of the water collecting portion 50b and having a plurality of drainage holes, and is separable from the water collecting portion 50 b. In this case, the water collecting portion 50b is preferably understood as a device for collecting moisture including fur of the pet or sewage discharged through the drain hole.

Further, a discharge hole 51 is formed in a side surface portion of the water collecting portion 50b to discharge air from a bottom surface in cooperation with the air flow path. In this case, it is preferable that the discharge hole 51 is formed at a certain height from the bottom so as to prevent the moisture and foreign substances flowing into the water collecting part 50b from flowing out. Accordingly, the air flowing into the discharge hole 51 is discharged upward through the step portion 50a, and thus the abdomen side portion of the pet can be more easily dried.

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

Therefore, the state of the pet being dried can be confirmed through the projection window 41, and thus, the convenience of use and the safety of the product can be improved. In addition, the visual field of the pet is prevented from being blocked, so that the uneasy feeling of the pet can be reduced.

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

Preferably, the windshield cover 20 includes an inner surface portion 22 having an outer peripheral edge connected to the inner surface of the housing portion to surround the flow path and having a vent hole 21 formed therethrough, and an inlet 23 provided at a rear portion.

At this time, a nozzle is provided at the blowing 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 blowing hole 21.

Preferably, the air blowing hole 21 has a nozzle shape of: the outer circumference of the recess is recessed in the air discharge direction, and then protrudes to the accommodating space 10c side by a height corresponding to the depth of the recess. Therefore, the pet can be prevented from being injured by the nozzle.

On the other hand, the driving unit 60 connected to the case 10 and supplying air from behind is provided behind the case 10. Specifically, the driving unit 60 is preferably understood to be a device that sucks in, heats, and discharges air to the case 10.

Here, the front portion of the driving unit 60 and the rear portion of the housing 10 are coupled to each other by a coupling unit provided in a central portion, which is a space where the windshield 20 is disposed.

Specifically, it is preferable that the coupling means 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 inside the rotary lock portion 61 to elastically support the rotary lock portion 61 inside the driving portion 60.

Preferably, the hanging part 11 is integrally extended and protruded from at least one of the upper surface and the lower surface of the rear part of the case part 10.

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

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

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

Therefore, the rotation protrusion 61a is laterally rotated by the insertion long hole 13, thereby being received and coupled to the edge of the hanging hole 12. At this time, the locking part 61 is elastically supported to the driving part 60 side by the spring of the rotating body part 61 b. Accordingly, the hook 11 is closely attached and fixed between the rotation protrusion 61a that rotates in the lateral direction and the driving unit 60, thereby stably coupling the housing 10 and the driving unit 60.

Accordingly, when the rotary lock portion 61 is rotated, the rotary projection 61a is fixed by the rotary body portion 61b in a state of being received in the edge of the mounting hole 12, and thus the driving portion 60 and the housing portion 10 are kept coupled to each other. That is, since the driving unit 60 and the housing unit 10 are detachably coupled to each other by the rotary lock unit 61, the convenience of use of the product can be improved.

On the other hand, it is preferable that a protruding coupling partition wall 14 is formed on an edge of one of the driving portion 60 and the housing portion 10, which is opposite to the driving portion, and a short step portion 62 which is recessed stepwise and comes into contact with an inner peripheral surface of the coupling partition wall 14 is formed on the other opposite side. In this case, in one embodiment of the present invention, a case where the short portion 62 is formed in the driving portion 60 and the coupling partition 14 is formed in the housing portion 10 is illustrated and described as an example.

Here, it is preferable that the short table portion 62 and the coupling partition 14 have a sealing portion such as an elastomer for sealing at a connection portion between the driving portion 60 and the housing portion 10, and the lengths of the respective sides are made to correspond to each other.

Further, it is preferable that the coupling partition wall 14 is formed to protrude toward the driving portion 60 and to have a width corresponding to the width of the short table portion 62. Therefore, the inner periphery of the coupling partition wall 14 and the outer periphery of the short table portion 62 are joined to each other in a form fitting manner.

Further, the edge of the coupling partition wall 14 is formed corresponding to the width of the edge of the driving portion 60, and is coupled by surface contact therebetween, whereby the driving portion 60 and the housing portion 10 are coupled in a sealed state.

On the other hand, referring to fig. 3, it is preferable that the driving unit 60 includes a heater 80 for heating air and the exhaust fan 70 for mixing the air inside the accommodating space 10c with the air outside and sending the air to the housing 10 side.

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 causes the heater 80 to continuously generate heat until the internal temperature detected by the 1 st temperature sensor 69a reaches a preset temperature, and when the internal temperature reaches the preset temperature, the control unit 82 cuts off the power of 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 maintained within a predetermined range, thereby preventing the hair of the housed pet from being damaged due to excessive heat. In addition, since the control unit 82 cuts off the power supply when the heater 80 is overheated, 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 bidirectional suction fans in the pet hair dryer according to the embodiment of the present invention is illustrated and described as an example.

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

Therefore, the blade fans 75a and 75b communicate with the internal air inflow windows 64 and the external air inflow windows 65, which will be described later, to suck in the internal and external air, and the sucked air is discharged to the shrouds 76a and 76 b.

Specifically, it is preferable that the shrouds 76a and 76b extend outward in the radial direction in accordance with the shape of the blade fans 75a and 75b, and a shroud outlet 71 for discharging air is formed at one side. The bidirectional suction fan includes a 1 st bidirectional suction fan 70a communicating with the discharge port on one side of the wind shield 20, and a 2 nd bidirectional suction fan 70b communicating with the discharge port on the other side of the wind shield 20. By the above-described bidirectional suction fans 70a, 70b, the inside air and the outside air are mixed in a direct connection manner. In this case, the direct connection type is preferably understood to mean that the inside air and the outside air of the accommodating space 10c are directly connected without an additional flow path.

Here, it is preferable that the blade fans 75a and 75b of the 1 st and 2 nd bidirectional suction fans 70a and 70b are connected to motors independent of each other, and thus operate independently. Therefore, the discharge amount to the inside of the accommodating space 10c is increased to improve the drying efficiency.

Preferably, the 1 st bidirectional suction fan 70a includes a 1 st shroud outlet 71a formed to extend to one side, and the 2 nd bidirectional suction fan 70b includes a 2 nd shroud outlet 71b formed to extend to the other side.

In this case, the 1 st shroud outlet 71a and the 2 nd shroud outlet 71b are formed by being bent to be rounded forward. Further, it is preferable that the driving unit 60 includes discharge ports 72 for discharging air flowing from the exhaust fan 70 at both left and right sides at a front portion thereof, and the discharge ports communicate with the 1 st shroud discharge port 71a and the 2 nd shroud discharge port 71b, respectively. Therefore, the air discharged from the 1 st and 2 nd bidirectional suction fans 70a and 70b flows toward the discharge port 72.

In addition, a cutting device (not shown) for selectively cutting off the air flow may be provided at each of the 1 st shroud outlet 71a and the 2 nd shroud outlet 71 b. In this case, the cutting device is disposed to cross the inside of the 1 st shroud outlet 71a and the 2 nd shroud outlet 71b and to be separated at the time of cutting, and the cutting device is controlled by the control unit 82.

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

The 1 st and 2 nd bidirectional suction fans 70a and 70b include a 1 st motor and a 2 nd motor, respectively, and the 1 st motor and the 2 nd motor are each speed-controlled or power-controlled by a control unit 82.

Therefore, since the air is discharged in one direction, the flow direction of the air is biased to be adjusted. Of course, the 2 nd motor is turned off to stop the 2 nd bidirectional suction fan 70b, so that only the air inside the 1 st shroud outlet 71a can flow.

That is, since the cutting device and the motor are operated in parallel, when one of the devices malfunctions, the remaining device is activated to control the discharge of air.

Here, the 1 st light source 68a is provided at the 1 st shroud discharge opening 71a, the 2 nd light source 68b is provided at the 2 nd shroud discharge opening 71b, and the 1 st light source 68a and the 2 nd light source 68b are selectively lit by the control unit 82.

That is, the 1 st light source 68a and the 2 nd light source 68b are each formed of an LED lamp, and are turned off when the 1 st shroud outlet 71a and the 2 nd shroud outlet 71b are cut, and are turned on when the 1 st shroud outlet 71a and the 2 nd shroud outlet 71b are not cut. Accordingly, the 1 st light source 68a and the 2 nd light source 68b are turned on and off, and whether the cutoff device is driven or not can be 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, regardless of whether the cutoff device is driven or not. That is, the 1 st and 2 nd bidirectional suction fans 70a and 70b are selectively operated by the control unit 82, and a lamp is turned on when the fan is operated, so that whether the fan is operated or not can be easily checked, thereby improving convenience in use.

The 1 st and 2 nd two- way suction fans 70a and 70b are disposed along the vertical direction, and the discharge ports 72 are disposed to be shifted from each other in both sides. That is, it is preferable that the driving unit 60 is provided at both sides thereof, and one side is higher than the other side.

The 1 st and 2 nd bidirectional suction fans 70a and 70b are preferably disposed such that the 1 st and 2 nd shroud discharge ports 71a and 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 shroud exhaust port 71a and the 2 nd shroud exhaust port 71b to prevent leakage of the exhausted air.

At this time, the respective discharge ports 72 communicate with the inflow port 23, and the discharged air flows toward the windshield cover 20. Here, a protruding seal partition 23a is formed on one edge of the inflow port 23 and the discharge port 72, and a seal groove 63 that contacts the outer peripheral surface of the seal partition 23a is formed in a shape of 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 inlet 23 is discharged into the housing space 10c through the ventilation hole 21 of the wind-guard cover 20.

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

On the other hand, it is preferable that the 1 st and 2 nd bidirectional suction fans 70a and 70b are provided with 1 st and 2 nd suction ports 74a and 74b to suck the inside and outside air and mix the air with the air in a direct connection manner. In addition, a blocking unit (not shown) for selectively blocking the suction of the outdoor air is further provided behind the 1 st suction port 74a and the 2 nd suction port 74b according to circumstances. Specifically, the cutting means is preferably configured to recognize whether or not to cut by the control means 82.

Therefore, the blocking unit (not shown) is configured in a neutral state, and thus, when the 1 st suction port 74a and the 2 nd suction port 74b are opened, external air is sucked from the 1 st bidirectional suction fan 70a and the 2 nd bidirectional suction fan 70 b. When one of the 1 st suction port 74a and the 2 nd suction port 74b is cut off, only the outside air is sucked from the other side.

When the 1 st suction port 74a and the 2 nd suction port 74b are all cut off by the cutting means (not shown), the suction of the outside air is restricted, and the inside air of the accommodating space 10c is continuously circulated. That is, the amount of outside air sucked is adjusted by the cut-off means.

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

On the other hand, referring to fig. 6a and 6b, an internal air inflow window 64 through which air flows from the housing space 10c is formed in a front surface portion of a cover forming an external appearance of the driving unit 60, and an external air inflow window 65 through which outdoor 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 so that the size and arrangement of the holes penetrating through the inflow windows are different, thereby adjusting the opening area.

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

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

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

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

On the other hand, fig. 7 is a rear view showing a coupling state of a discharge fan in a modification of the pet hair dryer of the modification of the 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 configuration of the pet hair dryer according to the modification of the embodiment of the present invention is the same as that of the above-described embodiment, detailed description of the same configuration will be omitted, and the same reference numerals will be given to the same configuration.

As shown in fig. 7 and 8, it is preferable that an outlet 172 for discharging air flowing from the exhaust fan 170 is provided in a front portion of the driving unit 60, and the outlet 172 is configured as a pair and disposed on both side surfaces of the front portion of the driving unit 60. 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 bidirectional suction fan in which both sides of the suction port 174 communicate with the inside and the outside of the accommodating space 10c, respectively, and thus the inside air and the outside air of the accommodating space 10c are directly mixed.

Accordingly, the exhaust fan 170 is formed of a bi-directional suction fan, and mixes the inside air and the outside air in a direct-coupled manner, thereby forcibly sucking the outside drying air, so that a forced discharge amount of the inside air having a high humidity is increased, thereby improving the drying efficiency of the product.

Specifically, the exhaust fan 170 preferably includes a blade fan 175 and a shroud 176 having an inlet port formed through both sides of the blade fan 175 in the axial direction. Therefore, the air sucked from the vane fan 175 is discharged to the shroud 176.

Preferably, the shroud 176 is formed to extend outward in a radial direction in accordance with the shape of the blade fan 175, and a shroud discharge port 171 for discharging air is formed at one side thereof.

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

Each of the branched shroud discharge ports 171 is provided with a cutting device 173 for selectively cutting off the shroud discharge port 171. At this time, the cutting device 173 is driven by a motor controlled by the control unit 82.

Specifically, when the cutoff device 173 is disposed in the neutral state, air is discharged from each of the shroud discharge ports 171 in both directions, and when one of the shroud discharge ports 171 is cut, 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 shroud 176, and 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 lit according to whether both sides of the shroud discharge port 171 are cut.

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

Referring again to fig. 4 and 5, the driving unit 60 preferably includes a cover having an internal air inflow window (64 of fig. 6 a) for allowing air to flow from the accommodating space 10c in a front portion thereof to form an external appearance, a heater 80 provided behind the internal air inflow window (64 of fig. 6 a), and a discharge fan 70 for discharging air heated by the heater 80, wherein the internal air inflow window 64 includes a 1 st suction filter 90a for filtering foreign substances in the internal air, and the external air inflow window 65 includes a 2 nd suction filter 90b for filtering foreign substances in the external air. In this case, the 1 st intake filter 90a and the 2 nd intake filter 90b are preferably formed in a dense mesh shape so as to filter foreign matters such as fine dust by allowing air to pass therethrough, 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 the reed switch 66 disposed at a predetermined interval from the driving magnet 91 in a position of the driving unit 60.

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 distance between the reed switch 66 and the driving magnet 91 is changed to a predetermined distance or more, the control unit 82 turns off the power supply of the driving unit 60.

Therefore, it is possible to prevent a malfunction of a fan, a motor, or the like, which may occur when the first suction filter 90a and the driving unit 60 are not well coupled, due to the inflow of hairs, foreign substances, or the like into the driving unit 60, and thus it is possible to further improve the safety of the product.

Further, the heater 80 is preferably disposed in the driving unit 60 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 power supply to the heater 80, the motor, and the like. Specifically, the wiring board 67 is preferably understood as a device incorporating a substrate that supplies power to the heater 80, the motor, and the like, in accordance with the control of the control unit 82. Of course, the wiring board 67 is provided in an internal space of the driving unit such as the right inner wall, depending on the case.

On the other hand, referring to fig. 10 and 11, it is preferable that the driving unit 60 includes a 1 st temperature sensor 69a disposed separately 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 means 82 for controlling the power supply to be turned off according to 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 cuts off the power of the heater 80.

In addition, when the temperature detected by the 1 st temperature sensor 69a is decreased to a preset temperature or less, 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 predetermined range, the fur of the housed pet is prevented from being damaged by excessive heat. In addition, when the heater 80 is overheated, the power is cut off by the control unit 82, 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 accommodating space 10 c. Specifically, the 2 nd temperature sensor 69b is preferably provided at a position on one side of the driving unit 60 and in contact with 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 accommodating space 10c, and the air is naturally convected, so that the heated air flows upward. Therefore, the 2 nd temperature s2 detected by the 2 nd temperature sensor 69b provided on one side changes slowly.

The 1 st temperature sensor 69a is provided above the heater 80, so that the 1 st temperature s1 detected by the 1 st temperature sensor 69a rises in a short time due to the upward flow of the air heated by the heater 80. Therefore, the 1 st temperature sensor 69a described above can detect the temperature change of the inside air in advance.

That is, since the difference between the temperatures detected by the 1 st temperature sensor 69a and the 2 nd temperature sensor 69b becomes larger as time passes, it is possible to determine that the exhaust fan 70 is out of order when the difference between the temperatures is equal to or greater than a predetermined safety allowance. Therefore, when the difference in temperature is equal to or greater than a preset safety tolerance, 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, a fire occurring when the exhaust fan 70 fails can be prevented from occurring, thereby improving the safety of the product.

In addition, since the forced flow is generated in the housing space 10c when the exhaust fan 70 is normally operated, 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 operated within the range within the safety allowance value.

The heater 80 further includes an overheating prevention fuse 81 that is opened when the temperature is equal to or higher than a predetermined cutoff temperature. Specifically, the fuse 81 determines whether the heater 80 is overheated, and rapidly cuts off the power supply when the heater 80 is overheated, thereby improving the safety of the product.

On the other hand, the driving unit 60 further includes a dust sensor 92 for detecting dust in the housing 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 based on the transmitted signal, and lights up the light sources in different colors based on the cleanliness, thereby indicating the cleanliness. That is, the light is turned on in blue when the cleanliness is good, and is turned on in red when the cleanliness is not good. Accordingly, the user can recognize the cleanliness of the air inside the housing space 10c while the pet is being dried.

The driving unit 60 further includes an ion generator 93 for generating negative ions. Accordingly, when air is discharged into the housing space 10c, anions are mixed to provide clean air to the pet.

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

In this case, unless otherwise specified, the terms "including", "constituting", "including", or "having" as described above indicate that the corresponding constituent elements may be incorporated, and thus other constituent elements may be included instead of excluding other constituent elements. Unless otherwise defined, all terms including technical and scientific terms have the same meaning as commonly understood by one of ordinary skill in the art. Terms used in general, such as terms defined in dictionaries, should be interpreted as meaning corresponding to meanings in related art texts, and should not be interpreted as meaning abnormal or excessive in a case where the meaning is not clearly defined in the present invention.

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