In this case, the exhaust direction of the ventilation passage and the exhaust direction of the flow guide may be different from each other in the horizontal direction.

Meanwhile, the thermoelectric element may be disposed on the housing.

On the other hand, the electronic device includes a first heat sink disposed on one surface of the thermoelectric element, a second heat sink disposed on the other surface of the thermoelectric element, and a region in which the thermoelectric element is not disposed between the first heat sink and the second heat sink. It may further include an insulating material positioned.

Meanwhile, the flow guide may include an intake port disposed under the thermoelectric element and an exhaust port disposed on a side surface of the thermoelectric element.

In this case, the exhaust port may be disposed adjacent to a side surface of the housing.

Meanwhile, the exhaust port may be disposed between the center of the housing and the opening in a horizontal direction.

Meanwhile, the flow guide may have a plurality of exhaust ports for discharging the air heat-exchanged in the thermoelectric element.

In this case, the flow guide may have a first exhaust port disposed in a left area and a second exhaust port disposed in a right area with respect to the opening.

On the other hand, the opening may be spaced apart from the inner lower end of the housing.

In this case, the distance between the openings may be 1/10 to 1/8 times the vertical height of the inside of the housing.

Hereinafter, the present disclosure will be described in more detail with reference to the drawings.

The electronic device 10 may include a housing 100 , a thermoelectric element 110 , a flow guide 120 , a fan 140 , and a control circuit 150 .

Since the electronic device 10 can uniformly control the temperature inside the housing 100 as will be described later, an object, food, or plant that needs to maintain a specific temperature is stored inside the housing 100, or a companion animal prefers it. It may be a companion animal house by maintaining the temperature, but is not limited thereto.

The housing 100 is a frame surrounding the electronic device 10 . The housing 100 includes a floor, a wall surrounding it, and a top plate, and a cover may exist on the top plate.

The housing 100 has an opening 101 disposed on the front side. Through the opening 101 , a user may place an object, food, plant, or the like in the housing 100 , or an animal may enter and exit the housing 100 . Hereinafter, the direction in which the opening 101 of the housing 100 exists is referred to as the front side.

The housing 100 may have various three-dimensional shapes such as a tetrahedron, a rectangular parallelepiped, a cone, and a cylindrical shape. The bottom of the housing 100 may be a triangle, a square, or a circle. In addition, the shape of the housing 100 viewed from the front may be a triangle, a square, a pentagon, or a circle.

The cover 106 on the top plate of the housing 100 may be removable, or may be partially fixed to the housing. Between the upper plate of the housing 100 and the cover 106 , there may be a separate space distinguished from the inside of the housing 100 . Components included in an embodiment of the present disclosure and the like may be arranged in a separate space.

At least one ventilation hole 107 communicating with the outside is present in the cover 106, and the ventilation hole 107 may be disposed on the side surface or the rear surface. A portion of the air heat-exchanged in the thermoelectric element 110 to be described later may be ventilated to the outside through the ventilation hole 107 .

The housing 100 may include a handle 108 . A handle 108 may be present over the lid 106 . In addition, a plurality of handles 108 may be present on the side surface of the housing 100 . The handle 108 may have an extended structure, or may have a concave structure into the housing 100 .

The thermoelectric element 110 is an element using the Peltier effect, in which one surface is selectively cooled or heated according to the direction in which current flows, and may be referred to as a Peltier element. The thermoelectric element 110 may have a rectangular shape, and the size may be 4 cm to 5 cm in width and length, but it is not stable.

The thermoelectric element 110 may be disposed on the upper portion of the housing 100 , or may be disposed on the rear surface of the housing 100 . A plurality of thermoelectric elements 110 may be disposed in the electronic device 10 .

To explain the operation of the thermoelectric element 110 according to the current direction, when the current inside the thermoelectric element 110 flows in an arbitrarily set (+) direction, one surface of the thermoelectric element 110 is cooled and the other surface can be heated at the same time. , if it flows in an arbitrarily set (-) direction, one side that was cooled in the (+) direction is heated and the other side that was heated at the same time can be cooled.

The flow guide 120 guides the flow of air in a predetermined direction. The flow guide 120 of the present electronic device provides air inside the housing 100 to the thermoelectric element 110 , and the air heat-exchanged in the thermoelectric element 110 circulates in the housing 100 inside the housing 100 . discharge in a predetermined direction of The flow guide 120 may include an intake port 121 through which internal air enters and

exhaust ports

122 and 123 through which air is discharged.

A possible form and arrangement of the flow guide 120 will be described later with reference to FIGS. 3 and 4 .

The fan 140 is a blower [Fan] that causes the flow of air. The fan 140 may control the air circulation direction inside the housing 100 according to the arrangement position, and the arrangement position of the fan 140 is not limited. The fan 140 may be disposed inside the flow guide 120 or around the intake port 121 of the flow guide.

The fan 140 may transfer the air inside the housing 100 into the flow guide 120 in one direction. Also, the fan 140 may have a rotational intensity or rotational direction adjusted by a control circuit 150 to be described later. A plurality of fans 140 may be disposed, and each may be independently operated or controlled.

The control circuit 150 controls the current direction of the power supplied to the thermoelectric element 110 .

The control circuit 150 may be connected to a temperature sensor 151 capable of measuring a temperature inside the housing 100 , and may control the thermoelectric element 110 based on the sensed value. According to the value of the temperature sensor 151 , the control circuit 150 is supplied to the thermoelectric element 110 . The degree to which the thermoelectric element 110 is cooled or heated may be controlled by adjusting the current.

In this case, the control circuit 150 may control the thermoelectric element 110 in a pulse width modulation (PWM) method. For example, the control circuit 150 may calculate an operating duty based on a difference between the sensed temperature and the target temperature, and may supply power to the thermoelectric element 110 in a section corresponding to the calculated operating duty.

Also, the control circuit 150 may control the rotation of the fan 140 . For example, when the thermoelectric element 110 operates, the control circuit 150 may operate the fan 140 , and when the thermoelectric element 110 does not operate, the control circuit 150 may stop the start of the fan 140 . have. Alternatively, the thermoelectric element 110 may not operate and only the fan 140 may operate.

The control circuit 150 may be connected to the object detection sensor 152 . The object detection sensor 152 may detect the entrance or exit of an object inside the housing 100 or the position of the object. The control circuit 150 may operate or stop the thermoelectric element 110 and the fan when an object enters and exits according to the sensed value.

Taking the animal house as an example as an example, when the entry of the animal is detected through the object detection sensor 152 , the control circuit 150 operates the thermoelectric element 110 and the fan 140 even if the user does not individually control it. can be controlled to maintain an appropriate temperature.

The electronic device 10 may include a power supply 155 . The power supply device 155 may receive external power and may have a built-in battery. The arrangement and shape of the power supply device 155 are not limited, and may be directly connected to the control circuit 150 to supply power.

Therefore, taking the method of controlling the internal temperature of the electronic device 10 as an example, on the assumption that the temperature to be maintained inside the housing 100 is A, the temperature inside the housing 100 sensed by the temperature sensor 151 is If the temperature is higher than A, the control circuit 150 may cool one surface of the thermoelectric element 110 by adjusting the current. And the air inside the housing 100 may be guided to the flow guide 120 by the fan 140 .

The induced air inside the housing 100 may exchange heat with one surface of the cooled thermoelectric element 110 . The heat-exchanged air is discharged back into the housing 100 at a lowered temperature, so that the temperature of the air inside the housing 100 may be maintained at A.

In addition, if the temperature inside the housing 100 sensed by the temperature sensor 151 is higher than A, the control circuit 150 may heat one surface of the thermoelectric element 110 by adjusting the current. And the air inside the housing 100 may be guided to the flow guide 120 by the fan 140 .

The induced air inside the housing 100 may exchange heat with one surface of the heated thermoelectric element 110 . The heat-exchanged air is discharged back into the housing 100 at an elevated temperature, so that the temperature of the air inside the housing 100 may be maintained at A.

Meanwhile, the electronic device 10 may further include a ventilation flow path 130 .

The ventilation flow path 130 is a flow path for discharging the air heat-exchanged on the other surface of the thermoelectric element 110 not in contact with the flow guide 120 to the outside of the housing 100 . The ventilation flow path 130 may be disposed on the upper portion or the rear portion of the housing 100 .

The ventilation flow path 130 may have a communication structure, and may include one or

more ventilation holes

132 and 133 . The ventilation flow path 130 may include a separate ventilation inlet 131 , and a separate ventilation fan 145 may be attached thereto. The ventilation fan 145 may introduce external air in a predetermined direction and may also exhaust it.

Meanwhile, as in an embodiment of FIGS. 3 and 4 to be described later, the exhaust direction F _b of the ventilation flow path 130 and the exhaust direction F of the flow path guide 120 with respect to the horizontal direction of the electronic device 10 . _a ) may be the same or different.

Therefore, if the heat-exchanged air from the other surface of the thermoelectric element 110 is not properly discharged, the performance of the thermoelectric element 110 may be deteriorated. Therefore, the electronic device 10 can efficiently discharge the air heat-exchanged from the other surface of the thermoelectric element 110 to the outside of the housing 100 through the ventilation flow path 130 .

As described above, in the electronic device 10 according to the present embodiment, the electronic device 10 controls the flow guide 12 and the fan 14 to circulate the air inside the housing 100 in a desired shape according to the purpose of use. Also, it is possible to maintain a uniform temperature throughout the interior of the housing 100 .

As described above, although the electronic device 10 according to the present disclosure is shown in the form of a small house in the drawings, the present disclosure is not limited thereto, and may be applied to various products using the thermoelectric element 110 .

In addition, in the heating/cooling system in a structure including the opening 101 , heat exchange with external air and air inflow and outflow through the opening 101 are unavoidable. However, since the electronic device 10 according to the present disclosure can control the air circulation direction, the heat-exchanged air can be efficiently circulated inside the housing 100 .

Referring to FIG. 2 , the electronic device 10 may further include a first heat sink 111 disposed on one surface of the thermoelectric element 110 and a second heat sink 112 disposed on the other surface of the thermoelectric element 110 . have.

The heat sinks 111 and 112 are plates that emit or absorb heat, and one surface may be formed in the form of a fin. The heat sinks 111 and 112 may be advantageous for heat exchange by increasing a surface area in contact with air during heat exchange. The heat sinks 111 and 112 may be made of a material having high thermal conductivity. The inside of the

heat sinks

111 and 112 may be filled with a liquid such as coolant.

The heat sinks 111 and 112 are disposed in contact with or close to one surface and the other surface of the thermoelectric element 110 to be heated or cooled by the thermoelectric element 110 , and heat exchange with the air of the flow path guide 120 or the ventilation flow path 130 . do

Since a temperature difference occurs between the first heat sink 111 and the second heat sink 112 as they are cooled or heated, respectively, in order to minimize unnecessary heat exchange between the first heat sink 111 and the second heat sink 112, the first heat sink The heat insulating material 113 may be disposed between the 111 and the second heat dissipation plate 112 in a region where the thermoelectric element 110 is not disposed.

Since the heat insulating material 113 can prevent unnecessary heat exchange, it may be made of a material such as asbestos, cork, or glass wool having low thermal conductivity.

On the other hand, depending on the arrangement method of the intake port 121 and the

exhaust port

122, 123 of the flow guide 120 of the electronic device 10, the air circulation direction inside the housing 100 is may vary.

For example, the flow guide 120 may include an intake port 121 disposed under the thermoelectric element 110 and

exhaust ports

122 and 123 disposed on a side surface of the thermoelectric element 110 . At this time, the intake port 121 of the flow guide 120 is present under the thermoelectric element 110 , so that the air inside the housing 100 can directly exchange heat with the thermoelectric element 110 .

In addition, the

exhaust ports

122 and 123 may be disposed adjacent to the side surface of the housing 100 , and as shown in FIG. 7C , which will be described later, the

exhaust ports

122 and 123 are located at the center and opening of the housing 100 in a horizontal direction. It may be disposed between 101 .

The flow guide 120 may have a plurality of

exhaust ports

122 and 123 for discharging the air heat-exchanged in the thermoelectric element 110 , and further, the flow guide 120 is disposed on the left side with respect to the opening 101 . It may have a first exhaust port 122 that is formed, and a second exhaust port 123 that is disposed in the right area.

When the plurality of

exhaust ports

122 and 123 are disposed adjacent to the side surface of the housing 100 , the air discharged from the

exhaust ports

122 and 123 moves to the lower end of the housing 100 along the side wall inside the housing 100 . comes right down Therefore, even if the thermoelectric element 110 and the

exhaust ports

122 and 123 are disposed at the upper end of the housing 100 , the temperature can be uniformly adjusted up to the lower end of the housing 100 .

3 and 4 are views for explaining the structures of the flow path guide 120 and the ventilation flow path 130 according to an embodiment of the present disclosure, respectively.

The flow guide 120 may have a structure in which one intake port 121 is disposed at a lower end, and two

exhaust ports

122 and 123 are disposed opposite to each other in a linear direction. In the ventilation passage 130 , the two exhaust ports may be disposed opposite to each other in a linear direction, and a separate intake port may be disposed at an upper end thereof. In this case, the air traveling direction of the flow path guide 120 may be referred to _{as F a} _{, and the air traveling direction of the ventilation flow path may be referred to as F b} with respect to the horizontal direction.

When the heated or cooled air heat-exchanged on one surface of the thermoelectric element 110 is discharged through the flow path guide 120 , the cooled or heated air heat-exchanged on the other surface of the thermoelectric element 110 is discharged through the ventilation flow path 130 . Since it is discharged, the air of the flow path guide 120 in this embodiment is different from the air temperature of the adjacent ventilation flow path 130 . Therefore, unnecessary secondary heat exchange may occur between the flow path guide 120 and the ventilation flow path 130 .

Embodiment of Figure 3, the exhaust because the direction (F _a) are equal in the exhaust direction (F _b) and the flow guide 120 in the electronic apparatus 10, the ventilation passage 130, based on the horizontal direction, the flow guide ( 120) and the ventilation flow path 130 are horizontal, so unnecessary secondary heat exchange may occur.

Since it contrast, the embodiment of Figure 4, the exhaust direction of the exhaust direction (F _b) and the flow guide 120 in the electronic apparatus 10, the ventilation passage 130, based on the horizontal direction (F _a) are different, Since the direction in which the flow path guide 120 and the ventilation flow path 130 proceed is orthogonal, unnecessary secondary heat exchange can be minimized.

5 is a view for explaining the structure of the spaced apart opening 101 according to an embodiment of the present disclosure.

Referring to FIG. 5 , the opening 101 may be spaced apart from the inner lower end of the housing 100 . In the spaced apart structure, the lower end of the opening 101 may have a structure concave in the inner direction of the housing 100 as shown in FIG. 5 . In addition, the opening 101 may be disposed to be spaced apart from the inner top or side of the housing 100 .

If the vertical height inside the housing 100 is h ₁ , and the bottom separation distance of the opening 101 _{is referred to as h 2} , then the separation distance h ₂ of the opening is 1/10 of the vertical height h _{1 inside the housing.} to 1/8 times. The difference according to the presence or absence of the separation distance of the opening will be described later with reference to FIGS. 6A and 6B.

6A and 6B are diagrams schematically illustrating the air flow of the

internal exhaust ports

122 and 123 associated with the structure of the opening 101 according to an embodiment of the present disclosure.

According to an embodiment, the intake port 121 of the flow guide 120 is located at the upper center of the housing 100 , and the first exhaust port 122 is adjacent to the left side of the housing 100 with respect to the opening 101 , the second 2 It is assumed that the exhaust port 123 is disposed adjacent to the right side of the housing 100 with respect to the opening 101 .

As shown in FIG. 6A , when the heat-exchanged air is discharged through the

exhaust ports

122 and 123 , the heat-exchanged air flows out to the outside of the housing 100 through the opening 101 , and at the same time external air is introduced into the housing 100 . can

As shown in FIG. 6B , if the opening 101 is disposed to be spaced apart from the top, bottom, left, and right ends of the inside of the housing 100 , it is possible to reduce the amount of air flowing inside the housing 100 to the outside, so that the housing 100 ) can keep the air inside efficiently and uniformly.

For example, the housing interior of the vertical height (h ₁₎ 400mm to 500mm and the spacing of the openings (h ₂₎ is the air to the lower direction from the top to the case of about 50mm, an exhaust port (122, 123), the housing 100 Assume an embodiment that emits .

6A schematically illustrates an air flow when the lower ends of the opening 101 are not spaced apart. Since the

exhaust ports

122 and 123 discharge the open air from the top to the bottom, the heat-exchanged air is scattered from the bottom. At this time, some heat-exchanged air may flow out through the lower end of the opening 101 .

6B schematically illustrates an air flow when the opening 101 is spaced apart from the lower end of the housing 100 by 1/10 to 1/8 times the vertical height of the inside of the housing. Since the

exhaust ports

122 and 123 discharge the open air from the top to the bottom, the heat-exchanged air is scattered from the bottom. However, since the lower ends of the opening 101 are spaced apart, the amount of air discharged in the lower direction directly flowing out can be reduced.

That is, in the temperature control of the electronic device 10 having the opening 101 without a door, the opening 101 may be spaced apart from the lower end. Through this, the amount of heat-exchanged air directly outflow can be controlled.

Referring to FIG. 7A , the intake port 121 and the

exhaust ports

122 and 123 of the flow guide 120 may be disposed at the center of the upper end of the housing 100 .

Referring to FIG. 7B , the intake port 121 and the

exhaust ports

122 and 123 of the flow guide 120 may be rearwardly disposed between the center of the housing 100 and a wall surface opposite to the opening 101 in a horizontal direction.

Referring to FIG. 7C , the intake port 121 and the

exhaust ports

122 and 123 of the flow guide 120 may be disposed forward between the center of the housing 100 and the opening 101 in a horizontal direction.

In each of these examples, a result of comparing the internal temperature will be described later with FIG. 8 .

8 is a temperature analysis table of the electronic device 10 according to the arrangement of FIGS. 7A to 7C.

The inside of the housing 100 may be 400*600*500mm, and the opening 101 may have a height of 50mm spaced apart from each other. And, the numerical value of FIG. 8 is a situation in which the temperature inside the housing 100 is higher than the temperature of the outside by setting the front and rear displacement of the intake port 121 and the

exhaust ports

122 and 123 to 116 mm with reference to FIGS. 7b and 7c. is assumed. In addition, the amount of air generated by the fan 140 is 0.28 m^3/min, the external temperature of the housing 100 is 35°C, and the air temperature difference between the intake port 121 and the

exhaust ports

122 and 123 is equal to 3°C. It is assumed that the endothermic amounts are matched.

Referring to FIG. 8 , the lowest internal temperature was measured in the example of the front arrangement as shown in FIG. 7C in the above experiment.

That is, when the flow guide 120 is disposed as in the embodiment of FIGS. 7A to 7C , the

exhaust ports

122 and 123 may be disposed between the center of the housing 100 and the opening 101 . In this case, the heat loss to the outside of the housing 100 was the lowest, and the temperature inside the housing 100 could be efficiently controlled.

In addition, a situation in which the temperature outside the housing 100 is lower than the temperature inside may be considered. Even at this time, the electronic device 10 according to the present disclosure may change the positions of the intake port 121 and the

exhaust ports

122 and 123 of the flow guide 120 to adjust the internal air circulation direction.

That is, the electronic device 10 may set an optimal air circulation direction for temperature control inside the housing 100 using the flow guide 120 , and may efficiently control the temperature inside the housing 100 .

9 is a view for explaining the door 102 according to an embodiment of the present disclosure.

Referring to FIG. 9 , the electronic device 10 may further include a door.

The door 102 may selectively open and close the opening 101 . The door 102 may be of various types, such as a sliding door, an opening door, a detachable type, and the like.

The door 102 may have an effect of reducing heat exchange and movement of air inside and outside the housing 100 , and may minimize power consumption by maintaining a constant temperature inside the electronic device 10 . Furthermore, by attaching a hermetic door capable of completely blocking the opening 101 , the inflow of air through the opening 101 may be minimized.

In addition, as shown in FIG. 9 , the method may further include a hinge 103 connecting the upper end of the door 102 and the housing 100 , and the inner and outer directions of the housing 100 with respect to the hinge 103 . It may be possible to open and close in the direction. Since the hinge 103 is attached to the upper end, the door 102 can be opened and closed only by a pushing operation. In particular, when an animal enters the housing 100 directly, access is easier than when the hinge 103 is on the side. can do.

In an embodiment of the present disclosure, the intake port 121 and the

exhaust ports

122 and 123 of the flow guide 120 may be movable.

A moving frame 125 supporting the flow guide 120 may be disposed on the upper plate of the housing 100 . The moving frame 125 may be automatically moved by the control circuit 150 .

The electronic device 10 can arrange the positions of the intake port 121 and the

exhaust ports

122 and 123 of the flow guide 120 by the moving frame 125 according to the situation, and control the air circulation direction to efficiently You can adjust the temperature.

In an embodiment of the present disclosure, the thermoelectric element 110 may be disposed at the lower end of the housing 100 .

The electronic device 10 heats or cools the lower end of the housing 100 in a heat conduction manner by the thermoelectric element 110 disposed at the lower portion, and at the same time discharges the heat-exchanged air into the housing 100 using the flow guide 120 . can do.

Considering the case where the flow guide 120 is not used, the thermoelectric element 110 may heat or cool the lower end and adjust the temperature inside the housing 100 . Therefore, there is a problem that a temperature difference occurs inside, and it takes a long time to reach a desired temperature.

However, when the thermoelectric element 110 is disposed at the lower end and the flow guide 120 is used, the electronic device 10 transfers the heat-exchanged air through the flow guide 120 to the inside of the housing 100 in a desired direction. can be cycled.

Therefore, even when the thermoelectric element 110 is disposed at the lower end, the temperature inside the housing 100 can be uniformly and quickly controlled using the flow path guide 120 , and unnecessary heat exchange with the outside can control the above-described air circulation direction. can be prevented in this way.

In addition, although preferred embodiments of the present disclosure have been illustrated and described above, the present disclosure is not limited to the specific embodiments described above, and the technical field to which the disclosure belongs without departing from the gist of the present disclosure as claimed in the claims Various modifications are possible by those of ordinary skill in the art, and these modifications should not be individually understood from the technical spirit or prospect of the present disclosure.
