[0063] Fig. 1 is a perspective view of a heat pump according to one embodiment of the present invention. Fig. 2 is a cross-sectional view of the heat pump illustrated in Fig. 1. Referring to Figs. 1 and 2, a heat pump (S) according to one embodiment of the present invention may include a power unit (1) and a housing (3).

[0064] The power unit (1) provides a rotational driving force for liquid circulation and can be equipped to heat the liquid when power is applied. That is, the power unit (1) can generate rotational force when power is applied and circulate the liquid through the rotational force.

[0065] In addition, the power unit (1) can heat the liquid by applying different polarities to some and the remaining parts of the entire configuration. The power applied to the power unit (1) is a conventional AC power source, and the power source of a single negative or positive polarity can be alternately converted. In other words, the polarity can mean (+) polarity and (-) polarity.

[0066] The housing (3) has a space formed inside so that the power unit (1) can be placed therein. That is, the housing (3) can allow liquid to flow in, be heated by the power unit (1), and then be discharged to the outside.

[0067] In the past, the heating device and the circulation device were provided separately, but in the heating pump (S) according to one embodiment of the present invention, the power unit (1) performs heating and circulation simultaneously, so that space utilization efficiency can be maximized, and the heated liquid can be circulated immediately, so that the heat circulation speed can be improved.

[0068] Meanwhile, the housing (3) may be provided to receive power. That is, the housing (3) and the power unit (1) may be supplied with power of different polarities to heat the liquid flowing inside due to the difference in polarity between the housing (3) and the power unit (1). That is, the housing (3) may be supplied with power of a polarity opposite to that of at least a portion of the power unit (1) to heat the liquid flowing inside. Specifically, when the housing (3) and the power unit (1) come into contact with the liquid flowing inside the housing (3), heat may be generated in the liquid between the inner surface of the housing (3) and the power unit (1) that has received power of different polarities.

[0069] In addition, the large surface area of ​​the housing (3) and the power unit (1) enables rapid and uniform heating of the liquid. Furthermore, the material of the housing (3) and the power unit (1) may be a material with high conductivity so that current can flow. For example, the housing (3) may be a conductor based on at least one of aluminum, copper, iron, and tungsten.

[0070] Additionally, the material of the housing (3) may be a material with high light transmittance, allowing internal inspection while allowing current to flow through it. For example, the housing (3) may be composed of a transparent electrode including at least one of ITO, glass, aluminum, and carbon. Accordingly, the user can visually inspect the interior of the housing (3) to determine whether the components housed therein are functioning or abnormal.

[0071] In addition, the housing (3) and the power unit (1) may be configured to be a mixture of various materials. For example, the housing (3) and the power unit (1) may be configured to be a mixture of conductors and insulators. Therefore, the heat pump (S) according to one embodiment of the present invention may be configured so that, when power is applied, only the conductive portion of the housing (3) and the power unit (1) is energized. That is, the housing (3) and the power unit (1) may be configured to be divided into conductors and insulators in any region, thereby controlling the location and degree of heat generation. However, the materials of the housing (3) and the power unit (1) are not limited thereto.

[0072] The power unit (1) may include a motor (11), a shaft (13), and a rotor (15). The motor (11) may generate rotational driving force. The shaft (13) may be provided to be connected to the motor (11) and to receive power. That is, the shaft (13) may be provided to be connected to the motor (11) and to be rotatable.

[0073] A plurality of rotating bodies (15) may be provided on the shaft (13) and spaced apart from each other to enable rotation. That is, a plurality of rotating bodies (15) may be provided on the shaft (13) and spaced apart from each other. In other words, since a plurality of rotating bodies (15) are provided and spaced apart from each other, the contact area with the liquid flowing inside the housing (3) is maximized, and circulation of the liquid is promoted to maximize heating and heat circulation efficiency.

[0074] Additionally, each of the plurality of rotors (15) may be applied with a first polarity or a second polarity different from the first polarity. Accordingly, heat may be generated and the liquid may be heated due to the difference in polarity of each of the plurality of rotors (15). In other words, the plurality of rotors (15) may generate heat and efficiently transfer the heat generated by rotation to the liquid.

[0075] Specifically, the rotor (15) may include a first impeller (15a) and a second impeller (15b). The first impeller (15a) is coupled to a shaft (13) and may be applied with a first polarity. The second impeller (15b) is disposed on the shaft (13) at a distance from the first impeller (15a) and may be applied with a second polarity different from the first polarity. If the first polarity is positive, the second polarity may be negative, and if the first polarity is negative, the second polarity may be positive.

[0076] Meanwhile, the shaft (13) may be provided in a multi-stage structure. That is, the shaft (13) may be provided in a plurality corresponding to the number of rotating bodies (15) to provide a multi-stage structure. For example, when two first impellers (15a) are provided and two second impellers (15b) are provided, four shafts (13) may be provided to provide a four-stage structure.

[0077] Specifically, the shaft (13) may include a first shaft (131), a second shaft (133), a third shaft (135), and a fourth shaft (137). The first shaft (131) is arranged at the innermost side and has the longest length, so that a first impeller (15a) can be coupled to an end thereof. The second shaft (133) wraps around the first shaft (131), and has a shorter length than the first shaft (131), so that a second impeller (15b) can be coupled to an end thereof. The third shaft (135) wraps around the second shaft (133), and has a shorter length than the second shaft (133), so that a first impeller (15a) can be coupled to an end thereof. The fourth shaft (137) surrounds the third shaft (135) and is provided with a shorter length than the third shaft (135) so that the second impeller (15b) can be coupled to the end.

[0078] The first shaft (131), the second shaft (133), the third shaft (135), and the fourth shaft (137) independently rotate to independently rotate the first impeller (15a) and the second impeller (15b), and polarities can also be independently applied to the first impeller (15a) and the second impeller (15b). That is, the first impeller (15a) coupled to the first shaft (131) can be applied with the first polarity or the second polarity through the motor (11) and the first shaft (131). The second impeller (15b) coupled to the second shaft (133) can be applied with the first polarity or the second polarity through the motor (11) and the second shaft (133). The first impeller (15a) coupled to the third shaft (135) can have the first polarity applied or the second polarity applied through the motor (11) and the third shaft (135). The second impeller (15b) coupled to the fourth shaft (137) can have the first polarity applied or the second polarity applied through the motor (11) and the fourth shaft (137).

[0079] Specifically, a plurality of first impellers (15a) are spaced apart from each other on the shaft (13), and a plurality of second impellers (15b) are provided and can be arranged between the plurality of first impellers (15a). That is, the first impellers (15a) and the second impellers (15b) can be arranged alternately along the longitudinal direction of the shaft (13). Accordingly, the first impellers (15a) and the second impellers (15b) can heat the liquid more efficiently depending on the applied polarity, and can more effectively control the degree of heat circulation.

[0080] The first impeller (15a) rotates independently from the second impeller (15b), and when the first impeller (15a) rotates in the first direction, the second impeller (15b) may be arranged to rotate or stop in the first direction or in a second direction different from the first direction. The first direction may be clockwise and the second direction may be counterclockwise. In addition, the first direction may be counterclockwise and the second direction may be clockwise.

[0081] Specifically, when the first impeller (15a) rotates in the first direction, the second impeller (15b) can rotate in the first direction. In addition, when the first impeller (15a) rotates in the first direction, the second impeller (15b) can rotate in the second direction. Furthermore, when the first impeller (15a) rotates in the first direction, the second impeller (15b) can stop rotating.

[0082] In addition, when the second impeller (15b) rotates in the first direction, the first impeller (15a) can rotate in the first direction. In addition, when the second impeller (15b) rotates in the first direction, the first impeller (15a) can rotate in the second direction. Furthermore, when the second impeller (15b) rotates in the first direction, the first impeller (15a) can stop rotating.

[0083] That is, the rotation direction of the first impeller (15a) and the second impeller (15b) can be set in various ways in consideration of the amount of liquid flowing, the speed of the liquid supplied, the rotation speed of the first impeller (15a), and the rotation speed of the second impeller (15b). Accordingly, the heating degree of the liquid flowing inside the housing (3) and the circulation speed of the liquid can be precisely controlled.

[0084] Meanwhile, the housing (3) may include a housing main body (31), a housing rear part (32), and a housing front part (33). The housing main body (31) may be provided to surround the power unit (1). That is, the housing main body (31) is provided in a hollow cylindrical shape, and the power unit (1) is arranged inside, and liquid can flow inside.

[0085] The housing rear portion (32) is positioned at the rear of the housing main body portion (31) to allow liquid to flow in by connecting the inside and outside of the housing main body portion (31). Specifically, the housing rear portion (32) may include a housing rear main body portion (321), a housing rear through hole (322), and a housing rear extension portion (323).

[0086] The housing rear body part (321) can be connected to the rear of the housing body part (31) to close the rear of the housing body part (31). The housing rear through hole (322) can be formed through the center of the housing rear body part (321) to allow liquid to flow into the housing body part (31).

[0087] The housing rear extension (323) can extend rearwardly while surrounding the housing rear penetration hole (322). That is, the housing rear extension (323) can guide liquid to stably flow into the housing main body (31).

[0088] The housing front portion (33) may be arranged in front of the housing main body portion (31) to connect the inside and outside of the housing main body portion (31) so that liquid flowing into the housing rear portion (32) passes through the power unit (1) and flows out to the outside. Specifically, the housing front portion (33) may include a housing front main body portion (331), a housing front through hole (332), and a housing front extension portion (333).

[0089] The housing front body part (331) is coupled to the front of the housing body part (31) to close the front of the housing body part (31). The housing front through hole (332) is formed through the center of the housing front body part (331) so that the liquid flowing inside the housing body part (31) can be heated by the power unit (1) and flow out to the outside by the rotational force of the power unit (1).

[0090] The housing front extension (333) can extend forward while surrounding the housing front penetration hole (332). That is, the housing front extension (333) can guide liquid to flow stably from the inside of the housing main body (31) to the outside.

[0091] Additionally, the housing (3) may include an outer housing (3a) and an inner housing (3b). The inner housing (3b) may be arranged to face the power unit (1), and the outer housing (3a) may be provided with a shape corresponding to the inner housing (3b) and may be arranged spaced apart from it.

[0092] The outer housing (3a) and the inner housing (3b) are provided with a double structure to stably protect the power unit (1), stably heat the liquid flowing inside, minimize external influences, and maximize heating efficiency. The outer housing (3a) and the inner housing (3b) may each include a housing main body (31), a housing rear portion (32), and a housing front portion (33).

[0093] Fig. 3 is a perspective view of a heat pump according to one embodiment of the present invention. Fig. 4 is a cross-sectional view of the heat pump illustrated in Fig. 3. Hereinafter, when describing various embodiments of the present invention based on Figs. 3 to 20, redundant descriptions will be omitted, and descriptions will be focused on modified or added components.

A plurality of housing inlet portions (34) are formed to penetrate along the periphery of the housing main body (31) and are spaced apart from each other, and connect the inside and outside of the housing main body (31) so that liquid can flow in.

[0096] That is, the housing inlet (34) is arranged in the center of the housing main body (31) so that liquid can be introduced from the side of the housing (3), thereby minimizing the flow resistance of the liquid when the liquid is introduced facing the housing main body (31), and the liquid can be easily heated and discharged.

[0097] The housing front part (33) may be arranged in front of the housing main body part (31) to connect the inside and outside of the housing main body part (31) so that liquid flowing into the housing inlet part (34) passes through the power part (1) and flows out to the outside.

[0098] Specifically, the housing front portion (33) may include a housing front coupling portion (334), a housing front extension portion (335), and a housing front adjustment portion (336). The housing front coupling portion (334) may be coupled to the housing main body portion (31).

[0099] The housing front extension (335) may be provided to extend obliquely from the housing front coupling portion (334) away from the housing main body (31) so as to increase its cross-sectional area. That is, the housing front extension (335) may improve safety by allowing the liquid heated by the power unit (1) to flow out at a reduced speed and with a large flow rate. The housing front control portion (336) may be provided in front of the housing front extension (335) to control the flow rate of the liquid flowing out to the outside. The housing rear portion (32) may be arranged in the rear of the housing main body (31) to close the housing main body (31).

The outer housing (3a) and the inner housing (3b) may each include a housing main body (31), a housing inlet (34), a housing front portion (33), and a housing rear portion (32).

A plurality of rotating blades (157) are provided between the rotating main part (151) and the rotating outer part (155), and may connect the rotating main part (151) and the rotating outer part (155). That is, the rotating blade (157) can promote the flow of liquid by rotation. In other words, the liquid disposed therebetween is heated due to the difference in polarity between the power unit (1) and the housing (3), and the heated liquid can be discharged to the outside by the rotation of the rotating blade (157).

[0106] In addition, the rotating blade (157) can be at least partially closed. That is, the rotating blade (157) can be completely closed between the plurality of rotating blades (157) to maximize the heating area. In addition, the rotating blade (157) can be completely open between the plurality of rotating blades (157) to maximize the liquid circulation. In other words, the open area of ​​the rotating blade (157) can be set in consideration of the type of liquid, the number of rotating blades (157), the set temperature of the liquid, etc., so that heating can be performed efficiently and the circulation efficiency can be improved. In addition, each of the first impeller (15a) and the second impeller (15b) can include a rotating main body part (151), a rotating through part (153), a rotating outer part (155), and a rotating blade (157).

That is, the housing partition wall portion (51) may be formed to protrude from the inner surface of the housing (3) so as to be arranged between the first impeller (15a) and the second impeller (15b).

[0111] In addition, the housing partition wall portion (51) may be applied with a first polarity or a second polarity, and the entire plurality of rotating bodies (15) may be applied with a polarity different from that of the housing partition wall portion (51). That is, the housing partition wall portion (51) may be applied with a first polarity or a second polarity, and the entire first impeller (15a) and the second impeller (15b) may be applied with a polarity different from that of the housing partition wall portion (51), so that the liquid can be heated by the polarity difference.

[0112] In addition, the housing partition wall (51) protrudes so that the end faces the first impeller (15a) and the second impeller (15b), thereby delaying the flow of liquid flowing inside the housing (3) and maximizing the heating of the liquid.

[0113] A plurality of shaft partition walls (53) are formed to protrude from the shaft (13) to control the flow rate of liquid flowing inside the housing (3). In addition, the shaft partition walls (53) may be formed to protrude from the outer surface of the shaft (13) to be arranged between a plurality of rotating bodies (15). That is, the shaft partition walls (53) may be formed to protrude from the outer surface of the shaft (13) to be arranged between the first impeller (15a) and the second impeller (15b).

[0114] In addition, the shaft partition wall (53) may be applied with a first polarity or a second polarity, and the entire plurality of rotating bodies (15) may be applied with a polarity different from that of the shaft partition wall (53). That is, the shaft partition wall (53) may be applied with a first polarity or a second polarity, and the entire first impeller (15a) and the second impeller (15b) may be applied with a polarity different from that of the shaft partition wall (53), so that the liquid can be heated by the polarity difference.

[0115] In addition, the shaft partition wall portion (53) may be provided with a protrusion height smaller than the height of the first impeller (15a) and the height of the second impeller (15b). Accordingly, the shaft partition wall portion (53) rotates together with the shaft (13) and can improve the flow speed of the liquid, thereby increasing the heat circulation efficiency. The housing partition wall portion (51) and the shaft partition wall portion (53) may be provided separately or together.

[0116] Fig. 10 is a drawing showing a heat pump including a housing slot portion according to one embodiment of the present invention. Fig. 11 is a drawing showing a heat pump including a shaft slot portion according to one embodiment of the present invention.

[0117] Referring to FIGS. 10 and 11, a heat pump (S) according to one embodiment of the present invention may include a slot portion (7). The slot portion (7) is provided in the housing (3) or shaft (13) so that a rotating body (15) can be attached or detached.

[0118] The slot portion (7) may include a housing slot portion (71) and a shaft slot portion (73). The housing slot portion (71) may be provided on the inner surface of the housing (3) so that a plurality of rotating bodies (15) can be attached and detached.

[0119] In addition, the housing slot portion (71) may be provided to surround the outer end of the rotating body (15). That is, the housing slot portion (71) may be inserted and coupled with the outer end of the rotating body (15), so that the number of rotating bodies (15) coupled to the shaft (13) can be conveniently adjusted. In addition, the housing slot portion (71) may be spaced apart from the outer end of the rotating body (15) by a predetermined distance or may be in contact with it to the extent that rotation is not impeded, so that rotation can be easily performed.

[0120] The shaft slot portion (73) may be provided on the outer surface of the shaft (13) so that a plurality of rotating bodies (15) can be attached and detached. In addition, the shaft slot portion (73) may be provided so as to surround the center of the rotating body (15). That is, the shaft slot portion (73) may be inserted into the center of the rotating body (15) and coupled, so that the number of rotating bodies (15) coupled to the shaft (13) can be conveniently adjusted. In addition, the shaft slot portion (73) may be spaced apart from the center of the rotating body (15) by a predetermined distance or may be in contact with it to the extent that rotation is not impeded, so that rotation can be easily performed.

[0121] The housing slot portion (71) and the shaft slot portion (73) may be provided separately or together to fix the rotating body (15). Accordingly, the heating degree of the liquid and the circulation speed of the liquid can be conveniently controlled.

[0122] Fig. 12 is a cross-sectional view of a heat pump according to one embodiment of the present invention. Referring to Fig. 12, a housing (3) according to one embodiment of the present invention may include a housing main body (31), a housing front portion (33), a housing rear portion (32), and a housing through hole (35).

[0123] The housing main body (31) is provided to surround the power unit (1), the housing front part (33) is arranged at the front of the housing main body (31), and the housing rear part (32) can be arranged at the rear of the housing main body (31).

[0124] A plurality of housing penetration holes (35) are formed through the housing main body (31) and the housing front part (33) so that liquid can flow into and out of the housing main body (31). That is, the housing main body (31), the housing front part (33), and the housing rear part (32) form a cylindrical shape, and a plurality of housing penetration holes (35) are formed spaced apart from each other around the housing main body (31) and the housing front part (33), so that the overall volume of the heat pump (S) can be minimized. In addition, liquid can easily flow into the housing main body (31) through the housing penetration holes (35) formed in the housing main body (31), and after being efficiently heated by the power unit (1), the liquid can easily flow out to the outside through the housing penetration holes (35) formed in the housing front part (33).

[0125] Fig. 13 is a drawing showing a heat pump including a housing depression according to one embodiment of the present invention. Referring to Fig. 13, a housing (3) according to one embodiment of the present invention may include a housing main body (31), a housing depression (36), and a housing inlet hole (37).

[0126] The housing body (31) may be provided to surround the power unit (1). The housing recessed portion (36) may be formed recessed toward the shaft (13) on the outer surface of the housing body (31).

[0127] A plurality of housing inlet holes (37) are formed through the housing main body (31) and the housing recessed portion (36) so that liquid can flow in and out of the housing main body (31). In addition, the housing inlet holes (37) can be formed on one surface of the housing recessed portion (36) facing the rotating body (15).

[0128] Specifically, the housing recessed portion (36) can be formed by recessing at least a portion of the side of the housing (3) facing the shaft (13). In addition, the housing recessed portion (36) can receive power of a polarity opposite to that of the power unit (1) through the housing (3).

[0129] Accordingly, heat generation of the liquid can proceed between the rotating body (15) and the surfaces of the housing recessed portion (36) that face the rotating body (15) in the front-back direction. In addition, heat generation of the liquid can proceed between the surfaces of the shaft (13) and the housing recessed portion (36) that face the shaft (13) in the radial direction, thereby increasing the heat generation amount of the heat pump (S).

[0130] As the position, length, width, shape, etc. of the housing recessed portion (36) change, the gap and area between the housing recessed portion (36) and the rotating body (15) and shaft (13) to which power of different polarities is applied change, and therefore, the heat generation amount of the heat pump (S) may differ depending on the shape of the housing recessed portion (36).

[0131] The housing inlet hole (37) can be formed on a surface facing the front-back direction of the rotating body (15) of the housing recessed portion (36). As the rotating body (15) rotates, liquid can flow into the housing (3) through the housing inlet hole (37) formed in the housing recessed portion (36).

[0132] In addition, the rotating body (15) and the housing recessed portion (36) may be supplied with power having opposite polarities, so that heat may be generated in the liquid between the rotating body (15) and the housing recessed portion (36). Accordingly, the amount of liquid circulating inside and outside the housing (3) may increase due to the inflow of liquid into and out of the housing (3) through the housing inlet hole (37) formed in the housing recessed portion (36), the generation of eddies caused by the flow of liquid inside and outside the housing (3), or convection caused by the heat generation of the liquid inside the housing (3).

[0133] Fig. 14 is a perspective view showing a heat pump with one side of the housing open according to one embodiment of the present invention. Referring to Fig. 14, the housing (3) according to one embodiment of the present invention includes a housing main body (31) and may optionally include either a housing front portion (33) or a housing rear portion (32).

[0134] That is, the housing main body (31) is provided to surround the power unit (1), and the housing front part (33) can be arranged at the front of the housing main body (31), and the housing rear part (32) can be arranged at the rear of the housing main body (31). Since only one of the housing front part (33) and the housing rear part (32) is provided, the housing (3) can have either one of the surfaces facing the motor (11) in the front-back direction and the surface facing the rotor (15) in the front-back direction open. In addition, the housing (3) may be provided with both the housing front part (33) and the housing rear part (32), and each may be partially open. Furthermore, the housing (3) may not be provided with both the housing front part (33) and the housing rear part (32), so that both sides may be open.

[0135] That is, as the degree of opening of the housing (3) increases, the amount of liquid circulation in the housing (3) can increase. Therefore, the appropriate degree of opening and shape of the housing (3) can be selected in consideration of the desired amount of liquid circulation in the housing (3).

[0136] In addition, the degree of opening between the plurality of rotating blades (157) of the rotating body (15) can be set according to the situation, and at this time, the degree of opening of each rotating blade (157) and the degree of opening of the housing (3) can be set by taking into consideration the degree of opening of the housing (3).

[0137] Fig. 15 is a drawing showing a heat pump including a housing extension according to one embodiment of the present invention. Referring to Fig. 15, a rotating body (15) according to one embodiment of the present invention may include a rotating main body (151), a rotating through-part (153), a rotating outer part (155), a rotating blade (157), and a rotating support part (159).

[0138] The rotating body part (151) can form an outer appearance, and the rotating through part (153) can be formed through the center of the rotating body part (151) and inserted into the shaft (13). The rotating outer part (155) is spaced apart from the rotating body part (151) and can be provided to surround the rotating body part (151). A plurality of rotating blades (157) are provided between the rotating body part (151) and the rotating outer part (155) and can connect the rotating body part (151) and the rotating outer part (155). The rotating support part (159) is provided to surround the rotating through part (153) and can be formed to protrude from the center of the rotating body part (151).

[0139] In addition, the housing (3) may include a housing main body (31), a housing front part (33), a housing rear part (32), and a housing extension part (38). The housing main body (31) is provided to surround the power unit (1), the housing front part (33) is arranged in front of the housing main body (31) to close the housing main body (31), and the inner surface faces the rotation support part (159), and the housing rear part (32) is arranged in the rear of the housing main body (31) to close the housing main body (31).

[0140] The housing extension (38) may be extended from the inner surface of the housing front portion (33) toward the rotational penetration portion (153) and may be arranged on the inner side of the rotational support portion (159). That is, the housing extension (38) may be configured to extend from the inner side of the surface of the housing (3) facing the rotational support portion (159), and to be supplied with power through the housing (3) and inserted into the rotational support portion (159).

[0141] Specifically, the housing extension (38) can be inserted so as to extend from the housing (3) and receive power of the same polarity as the housing (3) and be spaced apart from the inner wall of the rotation support (159) that receives power of the opposite polarity to the housing (3). Accordingly, when viewed in the radial direction of the rotation body (15), configurations having opposite polarities of the power applied in the order of the housing (3), the rotation body (15) and the housing extension (38) can be alternately arranged to increase the heat generation amount of the heat pump (S).

[0142] In addition, the liquid located between the inner wall of the housing extension (38) and the rotation support (159) may generate additional heat when power of opposite polarities is applied to the housing extension (38) and the rotation support (159). Therefore, due to the additional heat generation of the liquid between the inner wall of the housing extension (38) and the rotation support (159), convection of the liquid located inside and outside the housing (3) may occur, thereby increasing the amount of liquid circulation inside and outside the housing (3).

[0143] Fig. 16 is a drawing showing a heat pump including a housing waterproofing unit according to one embodiment of the present invention. Referring to Fig. 16, a housing (3) according to one embodiment of the present invention may include a housing main body (31), a housing front portion (33), a housing rear portion (32), and a housing waterproofing unit (39).

[0144] The housing main body (31) is provided to surround the power unit (1), the housing front part (33) is arranged in front of the housing main body (31) to close the housing main body (31), and the housing rear part (32) is arranged in the rear of the housing main body (31) to close the housing main body (31). In addition, a plurality of housing penetration holes (35) are formed in the housing main body (31) and the housing front part (33) to allow liquid to flow in and out of the housing (3).

[0145] The housing waterproofing portion (39) may be arranged on the inside of the housing main body (31) to surround the shaft (13), to partition the motor (11) and the rotor (15), and to seal the motor (11). As described above, when viewed in the front-rear direction, a housing penetration hole (35) may not be formed in the area of ​​the housing (3) where the motor (11) is provided based on the housing waterproofing portion (39).

[0146] Accordingly, liquid may not flow into the space of the housing (3) that is sealed by the housing waterproofing member (39) and in which the motor (11) is accommodated. Accordingly, when constructing the heat pump (S), a non-waterproof motor (11) can be used, and other components vulnerable to moisture can be placed in the space, thereby improving design flexibility and reducing manufacturing costs.

[0147] Fig. 17 is a drawing showing a heat pump including a dual housing structure according to one embodiment of the present invention. Specifically, Fig. 17(a) shows that a plurality of through holes are formed in an outer housing (3a) and spaced apart from each other, and Fig. 17(b) shows that through holes are formed at the front and rear of the outer housing (3a), respectively.

[0148] Referring to FIG. 17, a housing (3) according to one embodiment of the present invention may include an outer housing (3a) and an inner housing (3b). The inner housing (3b) may be configured to accommodate a power unit (1) therein. The outer housing (3a) may be configured to accommodate the inner housing (3b) therein.

[0149] In addition, a space (V) through which liquid can flow may be formed between the inner housing (3b) and the outer housing (3a). At this time, the outer housing (3a) may be configured so as not to receive power. Accordingly, the wear rate of the outer housing (3a) is reduced, and accidents such as electric shock or burns when a user comes into contact with the outer housing (3a) can be prevented.

[0150] Fig. 17(a) illustrates that a plurality of housing penetration holes (35) are formed on the surface of the outer housing (3a) facing the inner housing (3b) in the front-back and radial directions. That is, since the liquid located in the space (V) can flow through the plurality of housing penetration holes (35) formed in the front-back and radial directions in the outer housing (3a), the amount of liquid flowing inside and outside the outer housing (3a) can increase.

[0151] In Fig. 17(b), the outer housing (3a) is illustrated as having at least one housing penetration hole (35) formed on each of a pair of surfaces (front and rear) facing the inner housing (3b) in the front-back direction. That is, the liquid located in the space (V) is surrounded by the inner housing (3b) and the outer housing (3a) in all directions except the front-back direction, so that the flow of the liquid into and out of the outer housing (3a) can be concentrated in the front-back direction.

[0152] Accordingly, the flow of liquid in the space (V) between the inner housing (3b) and the outer housing (3a) can have a relatively constant directionality in the limited space (V). That is, by measuring the flow speed of the liquid, the temperature of the liquid, etc. in the space (V), the performance of the heat pump (S) can be measured more easily.

[0153] Fig. 18 is a drawing showing a heat pump including a buffer member or a linear driving member according to one embodiment of the present invention. Fig. 18(a) shows a heat pump including a linear driving member and a buffer member, and Fig. 18(b) shows a heat pump including a linear driving member.

[0154] A power unit (1) according to one embodiment of the present invention may include a linear driving unit (17). The linear driving unit (17) is provided inside the housing (3) and can move the motor (11), shaft (13), and rotor (15) in at least one of the forward-rearward direction and the radial direction.

[0155] Specifically, the linear driving unit (17) may be supported on a surface facing the motor (11) of the housing (3) in the front-back direction. At this time, the linear driving unit (17) may be configured in the form of at least one linear actuator configured to move the motor (11) in the front-back direction. That is, one end of the linear driving unit (17) may be coupled to a surface facing the motor (11) of the housing (3) in the front-back direction, and the other end of the linear driving unit (17) may be coupled to the motor (11).

[0156] By moving the power unit (1) through the driving of the linear drive unit (17), the gap between the housing (3) and the power unit (1) can be adjusted to control the heat generation amount of the heat pump (S). Accordingly, even if the installation position and installation angle of the heat pump (S) are changed at the installation location of the heat pump (S), the heat generation amount of the heat pump (S) can be increased by moving the power unit (1) through the driving of the linear drive unit (17) so as to form an optimal gap between the housing (3) and the power unit (1) considering the changed installation position of the heat pump (S).

[0157] In addition, since the movement of the power unit (1) through the driving of the linear drive unit (17) itself generates the flow of liquid inside and outside the housing (3), it can improve the circulation of liquid inside and outside the housing (3). By using this, when the generation of rotational driving force through the rotating body (15) of the power unit (1) is limited, the liquid inside and outside the housing (3) can be circulated through the linear movement of the power unit (1) in the forward and backward direction through the linear drive unit (17), thereby minimizing the deterioration of the performance of the heat pump (S).

[0158] Meanwhile, the linear driving unit (17) may be supported on a surface radially facing the motor (11) of the housing (3). At this time, the linear driving unit (17) may be configured in the form of at least one linear actuator configured to move the motor (11) in the radial direction of the housing (3). That is, one end of the linear driving unit (17) may be coupled to a surface radially facing the motor (11) of the housing (3), and the other end of the linear driving unit (17) may be coupled to the motor (11).

[0159] In addition, since the movement of the power unit (1) through the driving of the linear drive unit (17) itself generates the flow of liquid inside and outside the housing (3), it can improve the circulation of liquid inside and outside the housing (3).

[0160] In addition, the heat pump (S) according to one embodiment of the present invention may include a buffer member (M). The buffer member (M) may be provided inside the housing (3) to absorb shock. That is, the buffer member (M) may be provided at a corner of a surface facing the rotating body (15) of the housing (3) in the front-rear direction.

[0161] In addition, the buffer member (M) can prevent the rotating body (15), shaft (13) and motor (11) from colliding with the housing (3) due to movement caused by the rotational driving force or vibration of the power unit (1) or linear movement caused by the driving of the linear driving unit (17).

[0162] In addition, the buffer member (M) is made of an elastic material such as rubber, and may be provided in a shape in which multiple polyhedrons protrude as shown in Fig. 18(a), but is not limited thereto.

[0163] Fig. 19 is a drawing showing a heat pump including an insulation part and a crank part according to one embodiment of the present invention. Specifically, Fig. 19(a) shows a crank part and a rotating insulation part, and Fig. 19(b) shows a crank part and a housing insulation part.

[0164] Referring to FIG. 19, a heat pump (S) according to one embodiment of the present invention includes a guide member (G) and a support member (H), and the power unit (1) may include a crank unit (18).

[0165] The guide member (G) may be configured to suppress movement of the housing (3) of the motor (11) in the radial direction and guide movement of the motor (11) in the forward and backward direction. Specifically, the guide member (G) has a length in the forward and backward direction corresponding to the range of motion of the motor (11) in the forward and backward direction according to the driving of the crank unit (18), and may be configured to have at least a portion thereof radially contact the motor (11) to suppress movement of the motor (11) in the radial direction and guide movement of the motor (11) in the forward and backward direction.

[0166] The support member (H) may be configured to support the guide member (G) in the radial direction of the housing (3). Specifically, one end of the support member (H) may be coupled to a surface radially facing the guide member (G) of the housing (3), and the other end may be coupled to the guide member (G).

[0167] The crank unit (18) may be configured to be supported on the inner surface of the housing (3) and move the power unit (1) in the forward and backward direction. Specifically, the crank unit (18) may include a flywheel (181), a crank shaft (182), a crank arm (183), a connecting rod (184), and a connecting member (185).

[0168] The flywheel (181) can store rotational energy resulting from the operation of the crank unit (18), thereby preventing sudden speed fluctuations of the crank unit (18). The crank shaft (182) is formed with an axis orthogonal to the front-rear direction, and can be configured to rotate by receiving power from a separate servo motor (not shown) and connected to it. The crank arm (183) can be configured to rotate by being connected to the crank shaft (182).

[0169] The connecting rod (184) can be connected to the crank arm (183) at one end and coupled to the connecting member (185) at the other end. That is, the connecting rod (184) is connected to the crank arm (183) to rotate, and can transmit power resulting from the rotation of the crank arm (183) to the connecting member (185).

[0170] The connecting member (185) can be connected to the connecting rod (184) at one end and coupled to the motor (11) at the other end. At this time, the connecting member (185) can move the motor (11) in the forward and backward direction according to the rotation of the crank arm (183).

[0171] That is, the crank part (18) can adjust the gap between the housing (3) and the power part (1) by moving the power part (1) in the forward and backward direction, thereby controlling the heat generation amount of the heat pump (S).

[0172] In addition, since the movement of the power unit (1) through the driving of the crank unit (18) itself generates the flow of liquid inside and outside the housing (3), it can improve the circulation of liquid inside and outside the housing (3).

[0173] Meanwhile, an insulating member (9) may be provided in the housing (3) or the rotating member (15) to suppress the flow of current. The insulating member (9) may include a housing insulating member (91) and a rotating insulating member (93). The rotating insulating member (93) may be provided in the rotating member (15) and may be formed of an insulator to suppress the flow of current.

[0174] In addition, the rotation insulation part (93) may be configured in the shape of a circular plate with a groove formed in the center so that the shaft (13) and the housing (3) are spaced apart from each other by a predetermined distance in the radial direction of the shaft (13) and so that the housing (3) and the housing (3) are spaced apart from each other by a predetermined distance in the radial direction of the housing (3).

[0175] That is, the rotation insulation part (93) can be configured so that at least a portion thereof is coupled to the surface facing the motor (11) of the rotation body (15). Accordingly, the heated liquid between the housing (3) and the rotation body (15) to which power of different polarities is applied can be circulated, when viewed in the front-back direction, mostly in the area of ​​the housing (3) in which the rotation body (15) is provided, with respect to the rotation insulation part (93), and outside the housing (3) adjacent thereto.

[0176] That is, when viewed from the front-back direction, the heat generation of the heat pump (S) and the circulation of liquid inside and outside the housing (3) can occur mostly in the area of ​​the housing (3) equipped with the rotating body (15) based on the rotating insulation part (93) and the outside of the housing (3) adjacent thereto.

[0177] In addition, when viewed from the front-back direction, the motor (11), shaft (13) and crank section (18) located in the area of ​​the housing (3) equipped with the motor (11) with respect to the rotational insulation section (93) may have their wear rate reduced due to the heated liquid inside the housing (3).

[0178] In addition, when the power unit (1) moves by driving the crank unit (18), the movement of the rotational insulation unit (93) coupled to the rotating body (15) can cause the flow of liquid inside and outside the housing (3). Therefore, the rotational insulation unit (93) can improve the circulation of liquid inside and outside the housing (3).

[0179] The housing insulation (91) may be formed of an insulator and provided inside the housing (3) to suppress the flow of current. In addition, the housing insulation (91) may be spaced apart from the shaft (13) by a predetermined distance in the radial direction of the shaft (13) and may be coupled to a surface of the housing (3) that faces the shaft (13) in the radial direction.

[0180] That is, the housing insulation part (91) can be positioned in the area of ​​the housing (3) in the direction in which the motor (11) is provided with respect to the rotating body (15) so as not to interfere with the range of motion of the rotating body (15) in the forward and backward direction according to the driving of the crank part (18) when viewed from the forward and backward direction.

[0181] Accordingly, the heated liquid between the housing (3) and the rotor (15) to which power of different polarities is applied can be circulated, when viewed in the front-back direction, mostly in the area of ​​the housing (3) in which the rotor (15) is provided, based on the housing insulation (91), and outside the housing (3) adjacent thereto.

[0182] That is, when viewed in the front-back direction, the heat generation of the heat pump (S) and the circulation of liquid inside and outside the housing (3) can occur mostly in the area of ​​the housing (3) where the rotating body (15) is provided with respect to the housing insulation (91) and the outside of the housing (3) adjacent thereto. In addition, when viewed in the front-back direction, the motor (11), shaft (13) and crank unit (18) located in the area of ​​the housing (3) where the motor (11) is provided with respect to the housing insulation (91) can have their wear rate reduced due to the heated liquid.

[0183] Fig. 20 is a drawing showing a heat pump including a blade control unit according to one embodiment of the present invention. The rotor (15) according to one embodiment of the present invention may include a blade control unit (158).

[0184] The blade control unit (158) is provided inside the rotation support unit (159) and can adjust the angle and position of the rotation blade (157). In addition, when the blade control unit (158) is provided, the rotation outer unit (155) can be deleted.

[0185] In addition, the blade control unit (158) may be configured to control at least one of the rotation angle of the rotating blade (157) with respect to the radial direction of the rotating support member (159) and the rotation angle of the rotating blade (157) with respect to the side of the rotating support member (159) facing the inner surface of the housing (3) in the radial direction of the rotating support member (159).

[0186] Specifically, the blade control unit (158) may include a first blade control unit (158a) and a second blade control unit (158b). The first blade control unit (158a) may be configured in the form of a motor so as to rotate the rotating blade (157) in the radial direction of the rotating support unit (159). Accordingly, the rotating blade (157) may rotate in the same direction as the motor rotation direction of the first blade control unit (158a).

[0187] That is, the blade control unit (158) can control the rotation angle of the rotating blade (157) with respect to the radial direction of the rotating support unit (159) by controlling the motor rotation of the first blade control unit (158a). The second blade control unit (158b) can include a guide rail (1581), a rail coupling member (1583), and a linear driving device (1585).

[0188] The first blade control unit (158a) can be rotatably coupled to the rotation support unit (159) so as to be rotatable about the side of the rotation support unit (159) facing the inner surface of the housing (3) in the radial direction of the rotation support unit (159).

[0189] That is, when an external force is applied to the first blade control unit (158a) by the second blade control unit (158b), the first blade control unit (158a) can rotate with respect to the side of the rotation support unit (159) facing the inner surface of the housing (3) in the radial direction of the rotation support unit (159) while being coupled to the rotation support unit (159).

[0190] The guide rail (1581) can be coupled to the inner surface of the rotation support member (159) along the radial direction of the rotation support member (159). The rail coupling member (1583) can be configured so that one end is coupled to a linear driving device (1585) and the other end is coupled to the guide rail (1581) so as to move along the guide rail (1581).

[0191] The linear driving device (1585) may be configured in the form of a linear actuator, and may be configured to enable linear movement through extension and contraction. Furthermore, the linear driving device (1585) may be coupled at one end to the first blade control unit (158a), and at the other end to the rail coupling member (1583). This linear driving device (1585) may be driven by a separate servo motor (not shown).

[0192] That is, when the linear driving device (1585) is extended, the rail coupling member (1583) can move in the radial direction of the rotation support member (159) along the guide rail (1581). And, according to the movement of the rail coupling member (1583), the linear driving device (1585) can rotate with respect to the side of the rotation support member (159) facing the inner surface of the housing (3) in the radial direction of the rotation support member (159). In addition, according to the rotation of the linear driving device (1585), the first blade control member (158a) coupled to the linear driving device (1585) and the rotation blade (157) coupled to the first blade control member (158a) can rotate.

[0193] Alternatively, when the linear drive device (1585) is retracted, the rail coupling member (1583) can move along the guide rail (1581) in the opposite direction to when the linear drive device (1585) is extended. In addition, the rotary blade (157) can rotate in the opposite direction to when the linear drive device (1585) is extended.

[0194] That is, the blade control unit (158) can adjust the rotation angle of the rotary blade (157) with respect to the side of the rotary support unit (159) facing the inner surface of the housing (3) in the radial direction of the rotary support unit (159) by controlling the extension and contraction of the linear driving device (1585).

[0195] In addition, the rotating blade (157) may be configured in a curved shape with respect to the radial direction of the rotating support member (159). Accordingly, when the rotation angle of the rotating blade (157) changes, the amount and direction in which the rotating body (15) included in the heat pump (S) pushes the liquid may change.

[0196] In addition, the rotating blade (157) and the housing (3) may be supplied with power having opposite polarities. Accordingly, the heat generation amount of the heat pump (S) may vary depending on the gap and the facing area between the rotating blade (157) and the housing (3). At this time, the rotating blade (157) may be configured to have a curved shape with respect to the radial direction of the rotating support member (159), and since the radial direction of the rotating support member (159) is the same as the radial direction of the housing (3), when the rotation angle of the rotating blade (157) changes, the gap and the facing area between the rotating blade (157) and the housing (3) may vary.

[0197] Accordingly, by controlling the rotation angle of the rotating blade (157) through the blade control unit (158), the heat generation amount, liquid flow amount, and liquid flow direction of the heat pump (S) can be controlled.

[0198] While representative embodiments of the present invention have been described in detail above, those skilled in the art will appreciate that various modifications to the above-described embodiments are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the claims set forth below but also by equivalents thereof.
