Background Technology

[0002] Generally, a window air conditioner includes a compressor that pressurizes refrigerant inside the case and a condenser that condenses the refrigerant pressurized by the compressor to lower its temperature. Additionally, the window air conditioner includes an evaporator that performs heat exchange using the refrigerant whose temperature has been lowered by the condenser.

[0003] Window air conditioners are installed in windows and can be divided into an indoor section, through which air cooled by passing through an evaporator is supplied, and an outdoor section, through which air passing through a condenser is discharged, centered around the window air conditioner.

[0004] The air in the indoor section moves to the inside of the case, exchanges heat with the condenser, is cooled to a set temperature, and then is supplied back to the indoor section. Additionally, the air in the outdoor section passes through the condenser and exchanges heat, so the temperature of the refrigerant passing through the condenser is lowered.

[0005] Conventional window air conditioners remain installed in the window year-round, so there is a problem in that the space where the air conditioner is installed cannot be used during the winter months when the air conditioner is not in use.

[0006] In addition, when a refrigerator function is installed in a window air conditioner, there is a problem in that the cooling capacity of the refrigerator is reduced because a cooling system for independent refrigerator use is not provided.

[0007] In addition, when operating a refrigerator using the cooling system equipped in a window air conditioner, there is a problem in that the operating noise increases compared to the cooling system installed in a conventional refrigerator.

[0008] Furthermore, when air conditioners and refrigerators are installed as separate units, space is required for each, leading to reduced space efficiency. Therefore, there is a need to improve this situation.

[0009] The background technology of the present invention is disclosed in Korean Published Patent Application No. 10-2020-0058271 (published May 27, 2020; Title of Invention: Window-type Air Conditioner Assembly and Inflow Water Blocking Member for Window-type Air Conditioner Assembly). The problem to be solved

[0010] The objective of the present invention is to provide a window-type air conditioner refrigerator equipped with a thermoelectric module that can be used even during the winter season when the air conditioner is not used, and can perform the functions of both an air conditioner and a refrigerator.

[0011] In addition, the objective of the present invention is to provide a window-type air conditioner refrigerator equipped with a thermoelectric module that provides a cooling system capable of independently implementing the functions of an air conditioner and a refrigerator.

[0012] In addition, the objective of the present invention is to provide a window-type air conditioner refrigerator equipped with a thermoelectric module that can provide a structure with reduced operating noise when the refrigerator is operated using a cooling system provided in the window-type air conditioner.

[0013] In addition, the objective of the present invention is to provide a window-type air conditioner refrigerator equipped with a thermoelectric module that combines the functions of an air conditioner and a refrigerator, while saving installation space compared to installing the air conditioner and refrigerator as separate devices.

[0017] In addition, a technical feature is the ability to use the refrigerator even during the winter months when the air conditioner is not used.

[0018] Specifically, since the air conditioner's cooling system and the refrigerator's thermoelectric module operate independently, the refrigerator can be used independently by operating the thermoelectric module installed in the refrigerator even when the air conditioner is not in use.

[0019] In addition, an air conditioner and a refrigerator are installed on the inside of a single case section, and the case section is detachably installed on a window, which is a technical feature.

[0020] Specifically, the air conditioner and refrigerator are provided on the inner side of the case section, and since the case section is installed at the window, space efficiency can be increased compared to installing the air conditioner and refrigerator individually.

[0021] In addition, since the refrigerator is cooled using a thermoelectric module, a structure with reduced operating noise compared to a cooling system using a compressor can be provided.

Specific details for implementing the invention

[0037] The aforementioned objectives, features, and advantages are described in detail below with reference to the attached drawings, thereby enabling those skilled in the art to easily implement the technical concept of the present invention. In describing the present invention, detailed descriptions of known technologies related to the present invention are omitted if it is determined that such descriptions would unnecessarily obscure the essence of the invention. Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the attached drawings. In the drawings, the same reference numerals are used to indicate the same or similar components.

[0038] [Overall configuration of a window air conditioner refrigerator equipped with a thermoelectric module]

[0039] FIG. 1 is a side cross-sectional view of a window-type air conditioner refrigerator (1) equipped with a thermoelectric module according to one embodiment of the present invention, FIG. 2 is a perspective view showing the main configuration of a window-type air conditioner refrigerator (1) equipped with a thermoelectric module according to one embodiment of the present invention, and FIG. 3 is a perspective view showing the exterior of a window-type air conditioner refrigerator (1) equipped with a thermoelectric module according to one embodiment of the present invention.

[0040] As illustrated in FIGS. 1 to 3, a window-type air conditioner refrigerator (1) equipped with a thermoelectric module according to one embodiment of the present invention has a case part (10) installed in a part where a window is installed. In addition, a refrigeration part (20) that functions as a refrigerator and a heat exchange part (140) that functions as an air conditioner are installed inside the case part (10).

[0041] A thermoelectric module (160) that supplies cold air to the inside of the refrigeration unit (20) is installed in succession to the refrigeration unit (20). Additionally, the heat exchange unit (140) receives refrigerant through a compressor (128) and an expansion valve (126) installed in the machine room (120).

[0042] A control unit (130) may be installed inside the machine room (120), and the cooling system of the air conditioner and the cooling system of the refrigerator can be controlled independently by a single control unit (130). In a window-type air conditioner refrigerator (1) equipped with a thermoelectric module according to one embodiment of the present invention, the cooling system of the air conditioner and the cooling system of the refrigerator are configured separately, and the cooling system of the refrigerator uses a thermoelectric module (160) to reduce noise.

[0043] Meanwhile, when the freezing mode is used among the cooling modes of the refrigerator, cold air can be transferred from the air conditioner's cooling system to the refrigerator. If necessary, cold air from the heat exchanger (140) can be supplied to the inside of the refrigerator section (20) to cool the refrigerator section (20).

[0044] A window-type air conditioner refrigerator (1) equipped with a thermoelectric module according to one embodiment of the present invention is installed in a space where a conventional window-type air conditioner is installed, and can provide the function of a refrigerator along with the function of an air conditioner. The configuration of an air conditioner and the configuration of a refrigerator are each provided within a limited installation space, and in order to reduce the operating noise of the refrigerator, a cooling system that operates for the air conditioner function and a cooling system that operates for the refrigerator function are each provided.

[0045] The cooling system used for the air conditioning function cools the air passing through the inner flow path (90) through the compressor (128) and heat exchanger (140), and then discharges the cooled air to the front of the case section (10).

[0046] In addition, a window-type air conditioner refrigerator (1) equipped with a thermoelectric module according to one embodiment of the present invention is installed integrally on the inside of a case part (10) without installing an outdoor unit outside the building. Therefore, to reduce the overall operating noise of the window-type air conditioner refrigerator (1) equipped with a thermoelectric module, a thermoelectric module (160) is used for cooling the refrigerator.

[0047] The cooling system for the function of the air conditioner includes a machine room section (120) and a heat exchange section (140). The machine room section (120) includes a blower fan (122), a condenser (124), an expansion valve (126), a compressor (128), and a control section (130). The heat exchange section (140) is installed inside the inner flow path section (90), and the air flow path of the inner flow path section (90) and the air flow path of the refrigeration section (20) which functions as a refrigerator are separated.

[0048] In addition, the window-type air conditioner refrigerator (1) equipped with a thermoelectric module uses only one compressor (128) for cooling indoor air and uses a thermoelectric module (160) for cooling the refrigerator section (20), so it provides a low-noise operating structure when the refrigerator section (20) that functions as a refrigerator is used alone.

[0049] [Case Section]

[0050] FIG. 4 is a perspective view illustrating a heat dissipation hole (18) and a ventilation hole (13) according to an embodiment of the present invention. As shown in FIG. 4, the case part (10) forming the outer shape of a window-type air conditioner refrigerator (1) equipped with a thermoelectric module includes a first case (12) in which a machine room part (120) is installed on the inside, and a second case (15) in which other components excluding the machine room part (120) are installed on the inside.

[0051] The case part (10) can be implemented in various variations within the technical concept of being detachably installed on a window. The case part (10) according to one embodiment of the present invention has a rectangular shape extending in the vertical direction, and two spaces are partitioned in the vertical direction.

[0052] A partition wall (16) is provided on the inner side of the case section (10). Based on the partition wall (16), the first case (12) is located on the upper side of the partition wall (16), and the second case (15) is located on the lower side of the partition wall (16). The first case (12) is located on the upper side of the second case (15), and a machine room section (120) is located on the inner side of the first case (12). Additionally, a heat exchange section (140), a thermoelectric module (160), a refrigeration section (20), an inner flow path section (90), and an air guide section (210) are installed on the inner side of the second case (15).

[0053] The second case (15) is installed in succession to the first case (12), and the partition wall (16) is installed between the first case (12) and the second case (15). The partition wall (16) according to one embodiment of the present invention is in the shape of a plate extending in the horizontal direction, and the internal space of the first case (12) and the internal space of the second case (15) are partitioned by the partition wall (16). Accordingly, the hot air of the first case (12), where the machine room (120) is located, is blocked from moving into the interior of the second case (15), which is in a relatively low temperature state, thereby improving the operating efficiency of the window-type air conditioner refrigerator (1) equipped with a thermoelectric module.

[0054] Additionally, the case portion (10) further includes a heat dissipation hole portion (18) that forms a hole in the second case (15) facing the thermoelectric module (160) and forms a space for the thermoelectric module (160) to be connected to the outside of the case portion (10). Since the heat dissipation hole portion (18), which is an opening on the side of the case portion (10) facing the thermoelectric module (160), is provided, the air that has dissipated heat from the thermoelectric module (160) can be easily discharged to the outside of the case portion (10), and the cooling performance of the thermoelectric module (160) can be improved.

[0055] Additionally, the case portion (10) may further include an insulating member (17) installed on the side facing the refrigerator portion (20). The material of the insulating member (17) may have low thermal conductivity, and the insulating performance may be further enhanced by forming a plurality of holes in the insulating member (17) to utilize the insulating properties of air.

[0056] The materials of the insulating material (17) can be broadly divided into organic and inorganic materials, and organic materials include cork, cotton, felt, carbonized cork, foam rubber, etc. And the inorganic materials used in the insulating material (17) include asbestos, glass wool, quartz wool, diatomaceous earth, magnesium carbonate powder, magnesia powder, calcium silicate, etc., and various other materials are used as the materials of the insulating material (17).

[0057] An insulating member (17) according to one embodiment of the present invention has a square panel shape and is installed in a shape that is erected on both sides in the width direction of the refrigeration unit (20). The insulating member (17) is located on the outside of the refrigeration unit (20) and can improve the cooling performance of the refrigeration unit (20) by blocking external heat from being transferred to the refrigeration unit (20).

[0058] The inlet and outlet of the inner flow path (90) are located in front of the case section (10), and the inlet of the refrigeration section (20) is also installed in front of the case section (10). In addition, the machine room section (120) is located inside the first case (12) provided on the upper side of the case section (10), and the first case (12) may be separated from the second case (15) as needed. Thus, the first case (12) can be separated from the second case (15) for replacement or maintenance work on the machine room.

[0059] [Machine Room]

[0060] As illustrated in FIGS. 1 and 2, the machine room (120) is installed in the inner space of the case section (10) partitioned from the refrigeration section (20), and various modifications are possible within the technical concept of supplying refrigerant for heat exchange to the heat exchange section (140). The machine room (120) is spaced apart from the refrigeration section (20) and the inner flow path section (90), and is installed in the space partitioned from the space where the refrigeration section (20) and the inner flow path section (90) are installed.

[0061] In one embodiment of the present invention, a blower fan (122), a condenser (124), an expansion valve (126), and a compressor (128) are installed inside the machine room (120). Additionally, a control unit (130) for controlling the main components of a window-type air conditioner refrigerator (1) equipped with a thermoelectric module may also be installed inside the machine room (120).

[0062] A ventilation hole (13) for discharging hot air is installed on the rear side of the first case (12) in which the machine room (120) is installed. The ventilation hole (13) includes a plurality of holes penetrating the first case (12). Since a condenser (124) is installed in an upright position on the inner side of the machine room (120) facing the ventilation hole (13), air passing through the condenser (124) can be easily discharged to the outside of the case (10) through the ventilation hole (13).

[0063] And, on the inner side of the machine room (120) facing the condenser (124), a blower fan (122) is installed to supply air in the direction toward the condenser (124). Thus, when the blower fan (122) is operated to move air in the direction toward the condenser (124), the air that has passed through the condenser (124) and whose temperature has risen is discharged to the outside of the case part (10) through the ventilation hole (13).

[0064] Additionally, a condenser (124), an expansion valve (126), and a control unit (130) are installed inside the machine room (120), and the condenser (124), the expansion valve (126), and the control unit (130) are positioned inside the machine room (120) to avoid the air passage located between the blower fan (122) and the condenser (124). Therefore, even when the rotational speed of the blower fan (122) is low, the movement of air from the blower fan (122) toward the condenser (124) is facilitated, thereby reducing the increase in power consumption.

[0065] The expansion valve (126) expands the refrigerant supplied to the heat exchanger (140), and the compressor (128) compresses the refrigerant that has passed through the heat exchanger (140). The condenser (124) cools the refrigerant that has passed through the compressor (128). Since the connection structure and operating state of the blower fan (122), the condenser (124), the expansion valve (126), and the compressor (128) are identical or similar to those of a known refrigeration system for air conditioners, a detailed description thereof is omitted.

[0066] Meanwhile, the control unit (130) controls the operation of the compressor (128) and the thermoelectric module (160) and is installed inside the machine room (120).

[0067] [Refrigerator Section]

[0068] The refrigeration unit (20) is located inside the case unit (10), and various modifications can be implemented within the technical concept of storing items stored inside at a low temperature. The refrigeration unit (20) according to one embodiment of the present invention includes a refrigeration body unit (30) and a refrigeration door unit (50).

[0069] The refrigeration body (30) is located in front of the thermoelectric module (160) and can be implemented in various variations within the technical concept of forming a space for storing goods. The refrigeration body (30) according to one embodiment of the present invention forms an inner space for storing goods, and has an open shape at the front. A rear hole (42) is provided on the rear surface (40) of the refrigeration body (30), and cold air generated from the thermoelectric module (160) moves into the interior of the refrigeration body (30) through the rear hole (42).

[0070] The refrigerator door section (50) is located in front of the refrigerator body section (30), and various modifications can be implemented within the technical concept of opening and closing the entrance of the refrigerator body section (30). According to one embodiment of the present invention, the refrigerator door section (50) is rotatably installed on the refrigerator body section (30), and opens and closes the entrance of the refrigerator body section (30) by means of a rotating operation.

[0071] Since the functions of a refrigerator (20) and an air conditioner are respectively provided on the inner side of the case part (10) installed on the window, space efficiency can be increased compared to installing the air conditioner and refrigerator separately. In addition, since the refrigerator (20) and the air conditioner can be operated simultaneously in the summer and only the refrigerator (20) can be operated in the winter, the device can be operated throughout all four seasons, thereby improving user satisfaction with the use of the product.

[0072] [Inner Euro section]

[0073] FIG. 5 is a perspective view illustrating the state in which air moves along the inner flow path (90) according to one embodiment of the present invention.

[0074] As illustrated in FIGS. 1 and 5, the inner flow path (90) can be implemented in various variations within the technical concept of forming a passage through which air moves along the outer circumference of the refrigerator (20) located inside the case (10). The inner flow path (90) forms a passage through which air is introduced through the lower side of the refrigerator (20), guides the movement of air upward along the back side (40) of the refrigerator (20), and then forms a passage through which air is discharged through the upper side of the refrigerator (20).

[0075] A heat exchanger (140) is installed in the inner flow path (90), and air moving along the inner flow path (90) passes through the heat exchanger (140) and undergoes heat exchange, so that the air is discharged to the front of the case section (10) with the temperature of the air lowered. The inner flow path according to one embodiment of the present invention includes an inlet flow path (92), a connecting flow path (94), and an outlet flow path (96).

[0076] The inlet passage (92) is located at the lower side of the refrigerator section (20) and forms a passage through which air flows into the interior of the case section (10). One end of the inlet passage (92) forms an inlet for air to enter and is installed facing the front of the case section (10). Since the inlet passage (92) forms an air passage in a horizontal direction at the lower side of the refrigerator section (20), indoor air located at the front of the case section (10) moves into the interior of the case section (10) through the inlet passage (92).

[0077] The connecting channel (94) is connected to the inflow channel (92) and forms an air passage that extends in an up-and-down direction along the rear side of the refrigeration unit (20).

[0078] The exhaust passage (96) is located on the upper side of the refrigeration section (20) and is connected to the connecting passage (94) to guide the direction of movement of air that has moved upward along the connecting passage (94) toward the front of the case section (10). The exhaust passage (96) forms a passage that guides the air cooled by heat exchange with the heat exchange section (140) toward the front of the case section (10), and if necessary, the cold air moving along the exhaust passage (96) may be moved toward the inside of the refrigeration section (20).

[0079] An inlet grille (116) and an outlet grille (118) that do not regulate the air flow path may be installed at the inlet and outlet of the inner flow path (90). The inlet grille (116) installed at the inlet of the inner flow path (90) blocks external foreign matter from entering the inlet of the inner flow path (90). Additionally, the inlet grille (116) is an injection-molded product having a plurality of holes and is installed at the inlet of the inlet flow path (92).

[0080] The outlet grille (118) installed at the outlet of the inner flow path (90) blocks external objects, such as chopsticks or fingers, from entering the outlet of the inner flow path (90). Additionally, the outlet grille (118) is an injection molded product having a plurality of holes and is installed at the outlet of the discharge flow path (96).

[0081] Alternatively, an inlet electric grille unit (100) and an outlet electric grille unit (110) that operate by a control signal from a control unit (130) and open / close the flow path may be installed at the inlet and outlet of the inner flow path unit (90).

[0082] The inlet electric grill unit (100) is installed at the inlet of the inlet passage (92), and various modifications can be implemented within the technical concept of controlling the flow rate of air entering the inlet passage (92) or opening and closing the inlet of the inlet passage (92). The inlet electric grill unit (100) according to one embodiment of the present invention includes a first grill case (102) fixed in a frame shape at the inlet of the inlet passage (92), and a plurality of first vanes (104) rotatably installed inside the first grill case (102).

[0083] The first grill case (102) is formed in the shape of a square frame, and the first vane (104), which is rotatably installed in the first grill case (102), extends in the vertical direction. The upper and lower sides of the first vane (104) are rotatably installed in the first grill case (102), and a plurality of first vanes (104) are connected by links extending in the longitudinal direction of the first grill case (102).

[0084] Therefore, even if the user rotates only one first vane (104), the remaining first vanes (104) adjacent to the first vane (104) that received the operating force rotate together with the link. Alternatively, since the link connecting the first vanes (104) is connected to a drive motor or an electric motor, the drive motor or electric motor can be operated by a control signal from the control unit (130) to rotate the link. Thus, the rotation of the first vanes (104) is performed automatically, so that the inlet of the inflow channel (92) can be opened or closed.

[0085] The outlet electric grill unit (110) is installed at the outlet of the discharge channel (96), and various modifications can be implemented within the technical concept of controlling the flow rate of air discharged from the discharge channel (96) or opening and closing the outlet of the discharge channel (96). An outlet electric grill unit (110) according to one embodiment of the present invention includes a second grill case (112) fixed in a frame shape at the outlet of the discharge channel (96), and a plurality of second vanes (114) rotatably installed inside the second grill case (112).

[0086] The second grill case (112) is formed in the shape of a square frame, and the second vane (114), which is rotatably installed in the second grill case (112), extends in the vertical direction. The upper and lower sides of the second vane (114) are rotatably installed in the second grill case (112), and a plurality of second vanes (114) are connected by links.

[0087] Therefore, even if the user rotates only one second vane (114), the remaining second vanes (114) adjacent to the second vane (114) that received the operating force rotate together with the link. Alternatively, since the link connecting the second vanes (114) is connected to a drive motor or an electric motor, the drive motor or electric motor can be operated by a control signal from the control unit (130) to rotate the link. Thus, the rotation of the first vane (104) and the second vane (114) is automatically performed, so that the inlet of the inflow channel (92) and the outlet of the discharge channel (96) can be opened or closed.

[0088] [Heat exchange section]

[0089] The heat exchanger (140) is located inside the inner passage (90) and, since it exchanges heat with the air passing through the inner passage (90), it includes various types of heat exchangers within the technical concept of supplying cold air to the inside of the inner passage (90). In addition, the heat exchanger (140) is connected to a compressor (128) and an expansion valve (126) installed inside the machine room (120).

[0090] The heat exchanger (140) may be installed inside the inner flow path (90) located on the upper side of the refrigeration unit (20), and, if necessary, may also be installed inside the inner flow path (90) located on the lower side of the refrigeration unit (20). Various modifications are possible, such as the heat exchanger (140) being installed inside both the inner flow paths (90) located on the upper and lower sides of the refrigeration unit (20).

[0091] A heat exchanger (140) according to one embodiment of the present invention is installed at an angle on the inner side of an inner flow path (90) and exchanges heat with air passing through the inner flow path (90). A heat exchanger (140) according to one embodiment of the present invention is equipped with a refrigerant pipe through which refrigerant flows and a heat dissipation plate (176) in contact with the refrigerant pipe, and is installed at an angle on the inner side of the inner flow path (90). Therefore, since the surface area where the heat exchanger (140) exchanges heat with the air passing through the inner flow path (90) is increased, the heat exchange efficiency can be further improved.

[0092] When a heat exchanger (140) is installed on the inner side of the inlet passage (92), a first blower (150) is also installed in the inlet passage (92) together with the heat exchanger (140). Accordingly, air introduced into the inlet passage (92) passes through the heat exchanger (140) and is cooled, then passes through the first blower (150), moves upward along the connecting passage (94), and is discharged to the front of the case section (10) through the discharge passage (96).

[0093] A first blower unit (150) is rotatably installed in a position facing the heat exchanger (140). The first blower unit (150) is located inside the inner flow path (90), and the rotation of the first blower unit (150) generates a flow of air passing through the heat exchanger (140).

[0094] The first blower unit (150) includes a cross-flow fan installed inside the inner air passage unit (90). The motor provided in the first blower unit (150) operates by a control signal from the control unit (130), and the cross-flow fan, which receives power from the motor, rotates to generate a flow of air discharged through the discharge passage (96). The cross-flow fan is formed in a cylindrical shape and discharges air sucked into one side of the cross-flow fan to the other side of the cross-flow fan.

[0095] According to one embodiment of the present invention, a first blower unit (150) is rotatably installed inside the discharge channel (96), and a heat exchange unit (140) is installed upstream or downstream of the discharge channel (96) relative to the first blower unit (150).

[0096] [Refrigeration Bracket Section]

[0097] FIG. 8 is a perspective view illustrating a state in which a refrigeration bracket part (190) is positioned in front of a thermoelectric module (160) in one embodiment of the present invention, and FIG. 9 is a perspective view illustrating a state in which a second blower part (200) is positioned in front of a thermoelectric module (160) in one embodiment of the present invention.

[0098] As illustrated in FIGS. 8 and 9, the refrigeration bracket is installed in front of the rear hole portion (42) provided in the refrigeration unit (20) or installed in the rear hole portion (42). The refrigeration bracket portion (190) can be implemented in various modifications within the technical concept of guiding cold air generated from the thermoelectric module (160) into the interior of the refrigeration unit (20) and forming a flow path that guides air circulating in the refrigeration unit (20) to the thermoelectric module (160). The refrigeration bracket portion (190) according to one embodiment of the present invention includes a central case (192), a first bracket (194), and a second bracket (197).

[0099] A second blower unit (200) is installed on the inside of a central case (192) installed in front of a rear hole (42). The second blower unit (200) performs the operation of transferring cold air generated from a thermoelectric module (160) to the inside of a refrigerator (20). The second blower unit (200) is equipped with a motor and a fan connected to the motor, and is operated by a control signal from a control unit (130). The central case (192) is provided with a central ventilation hole (193) that is open at the front and rear or has a plurality of ventilation holes.

[0100] The fan equipped in the second blower unit (200) is an axial fan. An axial fan is one in which the direction of airflow is parallel to the rotation axis of the fan, and includes propeller fans, tubular axial fans, vane axial fans, etc.

[0101] A plate-shaped first bracket (194) extending upward from the central case (192) is provided with a plurality of first ventilation holes (195). Additionally, a plate-shaped first bracket (194) extending downward from the central case (192) is also provided with a plurality of second ventilation holes (198) for air to move through.

[0102] Therefore, the air passing through the thermoelectric module (160) can be moved directly to the inside of the refrigerator (20) through the second blower unit (200) and the central ventilation hole (193) provided in the central case (192). Then, the air inside the refrigerator (20) moves back to the thermoelectric module (160) through the first ventilation hole (195) and the second ventilation hole (198), and then exchanges heat with the thermoelectric module (160), thereby lowering the temperature of the air.

[0103] [Thermoelectric Module]

[0104] FIG. 6 is a perspective view illustrating a thermoelectric module (160) according to one embodiment of the present invention, and FIG. 7 is an exploded perspective view of the thermoelectric module (160) according to one embodiment of the present invention.

[0105] As illustrated in FIGS. 6 and 7, the thermoelectric module (160) can be implemented in various variations within the technical concept of supplying cold air to the refrigeration unit (20) that functions as a refrigerator. In the present invention, since the machine room unit (120) operated for cooling indoor air and the thermoelectric module (160) operated for cooling the refrigeration unit (20) each operate independently, the convenience of using the device can be improved.

[0106] In addition, since the refrigerator is cooled using a thermoelectric module (160), it provides a structure with reduced operating noise compared to a cooling system using a compressor (128), thereby improving consumer satisfaction.

[0107] The thermoelectric module (160) according to the present invention is installed on the inside or outside of the refrigerator (20), and various modifications can be implemented within the technical concept of supplying cold air generated by the Peltier effect to the inside of the refrigerator (20).

[0108] A thermoelectric module (160) according to one embodiment of the present invention includes at least one of a first heat dissipation unit (162), a thermoelectric element (164), a second heat dissipation unit (170), a heat dissipation blower unit (180), a fixed bracket (182), a fixed frame (184), and a blower grille unit (186).

[0109] The rear side (40) of the refrigerator section (20) is provided with a rear hole section (42) which is a passage for air to move through, and a thermoelectric module (160) is installed through the rear hole section (42). One side of the thermoelectric module (160) is located inside the rear hole section (42), and the other side of the thermoelectric module (160) is located outside the refrigerator section (20) by passing through the air guide section (210).

[0110] FIG. 10 is a perspective view illustrating a state in which a first heat dissipation unit (162) is installed in front of an air guide unit (210) according to an embodiment of the present invention. As shown in FIGS. 8 to 10, the first heat dissipation unit (162) is installed in a state in contact with a thermoelectric element (164). Therefore, when one side of the thermoelectric element (164) in contact with the first heat dissipation unit (162) is cooled, the temperature of the first heat dissipation unit (162) decreases. Accordingly, the air that exchanges heat with the first heat dissipation unit (162) moves into the interior of a refrigerator unit (20) that functions as a refrigerator.

[0111] The first heat dissipation unit (162) is installed in a position facing the rear hole (42) provided on the back (40) of the refrigerator unit (20), and various modifications can be implemented within the technical concept of exchanging heat with air. In addition, the first heat dissipation unit (162) is manufactured from a material with high thermal conductivity, and a plurality of plates are stacked at set intervals to increase the contact area with air. Furthermore, a second blower unit (200) is installed in front of the first heat dissipation unit (162), and a refrigerator bracket unit (190) is installed in front of the second blower unit (200).

[0112] FIG. 11 is a perspective view illustrating a fixed bracket (182) and a first heat dissipation part (162) according to one embodiment of the present invention, and FIG. 12 is a perspective view illustrating a fixed bracket (182) and a fixed frame (184) according to one embodiment of the present invention.

[0113] As shown in FIGS. 11 and 12, a thermoelectric element (164), a fixing bracket (182), and a fixing frame (184) are installed on the rear side of the first heat dissipation unit (162). An air guide unit (210) is installed in a shape that surrounds the first heat dissipation unit (162) so that the cold air generated from the first heat dissipation unit (162) moves into the inside of the refrigeration unit (20).

[0114] The air guide section (210) is fixed to the outside of the refrigeration section (20) and has an opening that is open toward the back (40) of the refrigeration section (20). The fixing bracket (182) is fixed to the inside of the air guide, and the inside of the fixing bracket (182) is provided with a hole for installing a thermoelectric element (164) and a fixing frame (184).

[0115] A fixing frame (184) that surrounds the outer perimeter of a thermoelectric element (164) is installed on the inner side of the fixing bracket (182). The fixing bracket (182) is fixed to the inner surface of the air guide section (210) facing the refrigeration section (20), and the thermoelectric element (164) is located on the inner side of the fixing bracket (182).

[0116] A fixed frame (184) according to one embodiment of the present invention is formed in the shape of a square frame and prevents shaking of a thermoelectric element (164) located inside a fixed bracket (182). The fixed frame (184) is installed along the perimeter of the thermoelectric element (164) and is fixed inside the fixed bracket (182).

[0117] FIG. 13 is a perspective view illustrating a thermoelectric element (164) and a second heat dissipation part (170) according to one embodiment of the present invention, and FIG. 14 is a perspective view illustrating an air guide part (210) and a second heat dissipation part (170) according to one embodiment of the present invention.

[0118] As shown in FIGS. 6, 13 and 14, the thermoelectric element (164) is installed with one side in contact with the first heat dissipation part (162), and the part in contact with the first heat dissipation part (162) is cooled by power supply.

[0119] The thermoelectric element (164) is also called a ThermoElectric Module (TEM) and functions as a heat pump that absorbs heat from a low-temperature heat source and supplies heat to a high-temperature heat source. Additionally, the thermoelectric element (164) is capable of both cooling and heating operations.

[0120] The thermoelectric element (164) cools or heats using the Peltier effect. The Peltier effect is a phenomenon in which, when a potential difference is applied to both sides of an object, heat flows along with the current, creating a temperature difference at both ends.

[0121] In the thermoelectric module (160) according to one embodiment of the present invention, since a thermoelectric element (164) is used, cooling and heating can be performed with a single device, and the cooling device can be miniaturized and made lighter. In addition, since driving devices such as motors or compression devices are not required, noise and vibration are reduced or eliminated, and the operating life is extended. Furthermore, since a thermoelectric element (164) is used, temperature control is easy, and precise local cooling is possible.

[0122] The second heat dissipation unit (170) is installed in contact with the other side of the thermoelectric element (164), and various modifications can be implemented within the technical concept of exchanging heat with air. The second heat dissipation unit (170) is installed in a shape that penetrates the air guide unit (210). The second heat dissipation unit (170) according to one embodiment of the present invention includes a heat transfer plate (172), a heat transfer pipe (174), and a heat dissipation plate (176).

[0123] The heat transfer plate (172) is a plate-shaped member located on the inner side of the air guide section (210) and in contact with the thermoelectric element (164). In one embodiment of the present invention, the heat transfer plate (172) is in surface contact with the thermoelectric element (164), and the heat transfer pipe (174) extends into the inner side of the heat transfer plate (172).

[0124] The heat transfer plate (172) is fixed to the inner side of the air guide section (210) and installed in contact with the other side of the thermoelectric element (164). The heat transfer plate (172) can be formed in the shape of a square plate, and can be modified into various shapes as needed.

[0125] One side of the heat transfer pipe (174) is located inside the heat transfer plate (172), and the other side of the heat transfer pipe (174) penetrates the air guide section (210) and extends to the outside of the air guide section (210). Additionally, a heat transfer fluid is stored inside the heat transfer pipe (174).

[0126] The heat transfer pipe (174) is connected to a plurality of heat sinks (176) located on the outside of the air guide section (210). The plurality of heat sinks (176) are spaced apart at set intervals and installed in a stacked shape.

[0127] A heat dissipation blower (180) is installed on the outer side of the second heat dissipation unit (170) including a heat dissipation plate (176). The heat dissipation blower (180) is installed in succession to the second heat dissipation unit (170) and forms a flow of air passing through the second heat dissipation unit (170), thereby rapidly cooling the second heat dissipation unit (170).

[0128] The blower grille (186) is located on the outside of the heat dissipation blower (180) and is plate-shaped with a plurality of holes. The blower grille (186) is located on the inside of the heat dissipation hole (18) provided in the case part (10). Therefore, when an external foreign object moves toward the thermoelectric module (160) through the heat dissipation hole (18), it can be blocked by the blower grille (186) and prevented from moving into the inside of the thermoelectric module (160).

[0129] [Air Guide Section]

[0130] The air guide section (210) surrounds the thermoelectric element (164) and the first heat dissipation section (162) and is fixed to the refrigerator section (20). The air guide section (210) guides the cold air generated from the first heat dissipation section (162) to move to the inside of the refrigerator section (20) instead of moving to the inner flow path section (90).

[0131] As described above, the air guide section (210) is installed in a shape that surrounds a part of the thermoelectric module (160), and since the cold air generated from the thermoelectric module (160) is guided to the inside of the refrigeration section (20), the cooling efficiency of the refrigeration section (20) can be improved and electricity costs can be reduced.

[0132] [1st Electric Damper Section]

[0133] FIG. 15 is a cross-sectional view illustrating a state in which a heat exchanger (140) according to one embodiment of the present invention is installed in an inner flow path (90) located on the lower side of a refrigeration unit (20), and FIG. 16 is a cross-sectional view illustrating a state in which air moving along the inner flow path (90) according to one embodiment of the present invention moves into the inner side of the refrigeration unit (20).

[0134] As shown in FIGS. 15 and 16, a first electric damper unit (60) is installed on the upper side (32) of the refrigeration unit (20), and a second electric damper unit (70) can be installed on the lower side (36) of the refrigeration unit (20).

[0135] The first electric damper section (60) is installed in the first passage hole (34) provided on the upper side (32) of the refrigeration section (20) facing the inner flow path section (90). The refrigeration section (20) is formed in a roughly cuboidal shape, and a rear side (40) having a rear hole section (42) is installed on the rear side of the refrigeration section (20). The upper side of the rear side (40) is connected to the upper side (32), and the lower side of the rear side (40) is connected to the lower side (36).

[0136] Additionally, a first passage hole (34) forming a passage for air movement is provided on the upper side (32) of the refrigeration body (30). Air passing through the discharge passage (96) of the inner passage section (90) can move into the inner side of the refrigeration section (20) through the first passage hole (34).

[0137] And a second passage hole (38) forming a passage for air to move is provided on the lower side (36) of the refrigeration body (30). Through the second passage hole (38), air inside the refrigeration unit (20) can move to the inlet passage (92) of the inner passage section (90).

[0138] A first electric damper unit (60) installed on the upper side (32) of the refrigeration body (30) is operated by a control signal from a control unit (130) to open and close the first passage hole (34). The first electric damper unit (60) according to one embodiment of the present invention includes a first motor (62) that is fixed to the upper side (32) and supplies rotational power, and a plate-shaped first rotary door (64) that rotates by receiving power from the first motor (62). Since the first rotary door (64) opens and closes the first passage hole (34) by rotating downwards on the upper side (32), it guides the cold air passing through the discharge passage (96) of the inner passage section (90) into the inside of the refrigeration section (20).

[0139] [2nd Electric Damper Section]

[0140] The second electric damper unit (70) is installed in a second passage hole (38) provided on the lower side (36) of the refrigerator unit (20) facing the inner passage unit (90). The second electric damper unit (70) installed on the lower side (36) of the refrigerator body unit (30) is operated by a control signal from the control unit (130) to open and close the second passage hole (38). The second electric damper unit (70) according to one embodiment of the present invention includes a second motor (72) that is fixed to the lower side (36) and supplies rotational power, and a plate-shaped second rotary door (74) that rotates by receiving power from the second motor (72). The second rotating door (74) opens and closes the second passage hole (38) by rotating downward on the lower side (36), thereby guiding the air inside the refrigerator (20) into the inflow passage (92) of the inner passage section (90).

[0141] When the air conditioner function is not used in the window-type air conditioner refrigerator (1) equipped with a thermoelectric module, the first electric damper unit (60) and the second electric damper unit (70) are operated to open the upper and lower sides of the refrigerator unit (20). Accordingly, the flow of cold air moving through the inner air passage (90) is guided to the inside of the refrigerator unit (20), thereby improving the cooling performance of the refrigerator unit (20).

[0142] A window-type air conditioner refrigerator (1) equipped with a thermoelectric module has an air conditioner system and a refrigerator system each provided inside the case part (10), and can be connected to or separated from each other using a flow path and a duct.

[0143] In addition, a thermoelectric module (160) is applied to the refrigerator system to minimize operating noise. When the air conditioner function and the refrigerator function are operated simultaneously, the cold air from the air conditioner system can be transferred to the inside of the refrigerator section (20) that functions as a refrigerator through the inner air passage (90).

[0144] In addition, when the air conditioner is not running, the refrigerator system can operate separately to reduce noise, and when the refrigerator is in freezing mode, cold air can be delivered from the air conditioner system to the inside of the refrigerator section (20).

[0145] [Operation of a window air conditioner refrigerator equipped with a thermoelectric module]

[0146] Hereinafter, the operating state of a window-type air conditioner refrigerator equipped with an independent cooling system according to one embodiment of the present invention will be described in detail with reference to the attached drawings.

[0147] [Simultaneous operation of air conditioner and refrigerator]

[0148] When both the air conditioner function and the refrigeration function of the refrigeration unit (20) are used in a window-type air conditioner refrigerator equipped with an independent cooling system, the control unit (130) operates the machine room unit (120) and the thermoelectric module (160) respectively.

[0149] Cold air supplied to the heat exchanger (140) connected to the machine room (120) cools the air passing through the inner flow path (90) to a set temperature. Then, cold air generated from the thermoelectric module (160) is supplied to the inside of the refrigerator (20) to cool the items stored inside the refrigerator (20).

[0150] The control unit (130) checks the values ​​of the air conditioner indoor temperature sensor and the refrigerator internal temperature sensor in real time and controls the operation of the compressor (128) and the thermoelectric element (164) so ​​that the set target temperature can be reached.

[0151] When the difference between the indoor temperature and the air conditioner target temperature is 5°C or more, it operates in maximum cooling mode. And when the difference between the indoor temperature and the air conditioner target temperature is less than 5°C, the operation of the thermoelectric module (160) is stopped for efficient operation of the device. After opening the first passage hole (34) and the second passage hole (38) of the refrigeration unit (20), the cold air of the air conditioner can be supplied to the inside of the refrigeration unit (20) and the inside of the inner passage section (90) through the connected passage. As described above, the control unit (130) can control the operation of the first electric damper unit (60) and the second electric damper unit (70) according to the target temperature of the refrigeration unit (20).

[0152] [Air conditioner function only]

[0153] In a window-type air conditioner refrigerator equipped with an independent cooling system, when only the air conditioner function is operated, the control unit (130) operates only the machine room unit (120) and stops the operation of the thermoelectric module (160).

[0154] Cold air supplied to the heat exchanger (140) connected to the machine room (120) cools the air passing through the inner flow path (90) to a set temperature, and the cooled air is discharged to the front of the case (10) through the discharge path.

[0155] The control unit (130) checks the indoor temperature in real time through a sensor and controls the operation of the machine room unit (120) to reach the target temperature.

[0156] [Refrigerator function only]

[0157] When only the refrigerator function is operated in a window-type air conditioner refrigerator equipped with an independent cooling system, the control unit (130) operates only the thermoelectric module (160) and stops the operation of the machine room unit (120).

[0158] The thermoelectric module (160) supplies cold air to the inside of the refrigerator (20), so the temperature inside the refrigerator (20) is lowered. The cold air generated from the thermoelectric module (160) is guided to move toward the refrigerator bracket (190) by the air guide (210).

[0159] Cold air introduced into the refrigerator section (20) through the central ventilation hole (193) of the central case (192) in which the second blower section (200) is installed cools the refrigerator section (20) and then moves back to the thermoelectric module (160) through the first ventilation hole (195) and the second ventilation hole (198). Alternatively, a portion of the cold air introduced into the refrigerator section (20) through the central ventilation hole (193) may be moved to the inflow path (92) through the second passage hole (38).

[0160] In summer, the refrigerator unit (20) and the air conditioner can be operated simultaneously, and in winter, only the refrigerator unit (20) can be operated, so the device can be operated throughout all four seasons, which can improve user satisfaction with the use of the product.

[0161] The control unit (130) checks the temperature of the refrigerator unit (20) in real time through a temperature sensor installed in the refrigerator unit (20) and controls the operation of the thermoelectric module (160) to reach the target temperature.

[0162] In order to lower the temperature of the refrigerator section (20) in a short time, the inlet electric grill section (100) and the outlet electric grill section (110) are operated to block the inlet of the inlet passage (92) and the outlet of the discharge passage (96). Then, the first electric damper section (60) and the second electric damper section (70) are operated to open the first passage hole (34) and the second passage hole (38).

[0163] And as the compressor (128) and the first blower (150) are operated, the air cooled while passing through the heat exchanger (140) moves along the discharge path (96) and then moves into the inside of the refrigeration unit (20) through the first passage hole (34).

[0164] Cold air introduced into the interior of the refrigeration unit (20) cools the refrigeration unit (20), then moves to the inflow path (92) through the second passage hole (38), and then moves again to the heat exchange unit (140) through the connecting path (94).

[0165] Accordingly, the heat exchanger (140) operates in conjunction with the thermoelectric module (160) supplying cold air to the inside of the refrigerator (20) to supply additional cold air to the inside of the refrigerator (20), so that the temperature of the refrigerator (20) can be lowered in a short period of time.

[0166] Alternatively, if the thermoelectric module (160) fails, the heat exchanger (140) may be operated in an emergency operation mode using the above method.

[0167] When the refrigerator unit (20) is operated in freezing mode, the cooling system of the air conditioner is operated to guide the cold air from the heat exchange unit (140) to move into the interior of the refrigerator unit (20). At this time, the operation of the thermoelectric module (160) can be stopped.

[0168] When the refrigeration unit (20) is operated in refrigeration mode, only the thermoelectric module (160) can be operated to reduce operating noise.

[0169] When the air conditioner function is not used, the upper and lower sides of the refrigerator section (20) are opened to guide the flow of cold air moving through the inner flow path (90) into the interior of the refrigerator section (20), thereby improving the cooling performance of the refrigerator section (20).

[0170] Although the present invention has been described above with reference to the illustrated drawings, the present invention is not limited by the embodiments and drawings disclosed in this specification, and it is obvious that various modifications can be made by a person skilled in the art within the scope of the technical concept of the present invention.
