Description

Technical Field

[0001] The present invention relates to a thermogenic liquid circulator, and more particularly to a thermogenic liquid circulator with improved performance through structural design. Background Art

[0002] A typical device for heating and circulating a liquid is a boiler, which is classified into an electrical type, an electrode type, and the like according to the heating method.

[0003] Among them, the electrode type boiler makes the electrode rods with different polarity power supply directly or indirectly contact the liquid to achieve ionization of the liquid, thereby utilizing the heat generated when the ionized liquid flows to each polarity.

[0004] This method uses electrodes with different polarity power supplies. It has become popular and widely used due to its high thermal efficiency, relatively low installation and maintenance costs, simple structure, and easy management and control.

[0005] However, this conventional method can only generate heat, and requires a separate circulation device for circulating liquid. In addition, the conventional method requires the heat generating device and the circulation device to be provided in separate spaces, thus reducing space efficiency and heat circulation efficiency.

[0083] Hereinafter, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, the terms or words used in this specification and claims should not be interpreted as the conventional or dictionary meanings, but should be interpreted as the meanings and concepts that conform to the technical concept of the present invention based on the principle that the inventor can appropriately define the concept of the terms and describe his invention in the most preferred way.

[0084] Therefore, the embodiments of the present invention and the configuration described and illustrated in the accompanying drawings are merely the most preferred embodiments of the present invention, and do not represent all technical concepts of the present invention. It should be understood that when submitting this application, there may be multiple equivalents and modifications that can replace them.

[0085] Figure 1 is a perspective view of a heat generating liquid circulator 10 according to an embodiment of the present invention, Figure 2FIG. 1 is a cross-sectional view of a heat generating liquid circulator 10 according to an embodiment of the present invention.

[0086] like Figure 1 and Figure 2 As shown, the thermogenic liquid circulator 10 according to an embodiment of the present invention may include a housing 100 and a power unit 200 .

[0087] The power unit 200 can generate a rotational driving force for circulating the liquid and receive a unipolar power supply.

[0088] The housing 100 may be formed with at least one opening 110 through which liquid can flow. Also, the housing 100 accommodates the power unit 200 inside and receives a power source having a polarity opposite to that of the power unit 200.

[0089] Therefore, when the housing 100 and the power unit 200 are in contact with liquid, the liquid between the inner surface of the housing 100 and the power unit 200 will generate heat. At this time, the inner surface of the housing 100 is connected with different polarities.

[0090] That is, the conventional method has independently provided the heat generating device and the circulation device, but in the present invention, the functions are simultaneously performed by the housing 100 and the power unit 200 contained inside the housing 100. Therefore, the space efficiency of the heat generating liquid circulator 10 can be improved.

[0091] Furthermore, the heat generating liquid circulator 10 generates heat and circulates at the same position at the same time, so the heated liquid can be circulated immediately, thereby increasing the heat circulation speed of the heat generating liquid circulator 10 .

[0092] Furthermore, the conventional method is to supply power to an electrode rod of a given area, but the heat generating liquid circulator 10 according to an embodiment of the present invention supplies power to the casing 100 and the power unit 200 with a larger area, so that the liquid can be heated quickly and evenly.

[0093] At this time, as shown in the figure, the shape of the housing 100 can be cylindrical, but its shape is not limited thereto and can be various shapes including a polyhedron.

[0094] Furthermore, the housing 100 and the power unit 200 may be made of a material with high conductivity to facilitate the flow of current. In one example, the housing 100 may be a conductor based on at least one of aluminum, copper, iron, and tungsten.

[0095] Furthermore, the housing 100 may be made of a highly light-transmitting material that allows current to flow and allows the interior to be checked. In one example, the housing 100 may be made of a transparent electrode comprising at least one of ITO, glass, aluminum, and carbon. Therefore, the user can check the interior of the housing 100 and can check with the naked eye whether the components contained therein are working or whether there are any abnormalities.

[0096] Furthermore, the housing 100 and the power unit 200 may be formed by mixing a variety of materials. In one example, the housing 100 and the power unit 200 may be formed by mixing a conductor and an insulator. Therefore, when the power supply is turned on, the heat generating liquid circulator 10 can limit the power supply to the conductor parts of the housing 100 and the power unit 200. That is, any area of ​​the housing 100 and the power unit 20 can be divided into a conductor and an insulator to adjust the location and degree of heat generation. However, the material of the housing 100 and the power unit 200 is not limited thereto.

[0097] And, if Figure 1 and Figure 2 As shown, the opening 110 may be circular to facilitate the housing 100 to pass through, but its shape is not limited thereto. In one example, the opening 110 may be in various shapes including a polygon.

[0098] Furthermore, the opening 110 may be formed in any member of the thermal liquid circulator 10 including the housing 100. Also, when a plurality of openings 110 are formed on the thermal liquid circulator 10, each opening 110 may have a different shape.

[0099] And, if Figure 1 and Figure 2 As shown, the power unit 200 may include a motor 210 , a shaft 220 and a rotating body 230 .

[0100] The shaft 220 is connected to the motor 210 and transmits power.

[0101] The rotating body 230 is connected to the shaft 220 and rotates.

[0102] At this time, the rotating body 230 is supplied with a power source having a polarity opposite to that of the housing 100, and the shaft 220 may be composed of an insulator. At this time, the shaft 220 does not generate heat, and thus the wear rate of the shaft 220 can be reduced.

[0103] Alternatively, the shaft 220 is made of a conductor, and the shaft 220 and the rotating body 230 can be supplied with a power source having a polarity opposite to that of the housing 100. In this case, the heat generating area of ​​the heat generating liquid circulator 10 can be increased to increase the amount of heat generated.

[0104] Furthermore, the rotating body 230 may be in a shape as shown in the figure, but is not limited thereto, and the heat generating area may be adjusted by configuring the area of ​​the rotating shaft 231 described below or the number, area, angle, etc. of the blades 232. In one example, the blades 232 of the rotating body 230 may be connected to the side surface to maximize the heat generating area, thereby increasing the heat generating amount of the heat generating liquid circulator 10.

[0105] Figure 3 FIG. 1 is a cross-sectional view of a thermogenic liquid circulator 10 including a recessed portion 120 according to an embodiment of the present invention.

[0106] like Figure 3 As shown, the housing 100 may include a recessed portion 120 .

[0107] The recessed portion 120 may be formed by recessing at least a portion of a side surface of the shaft 220 facing the housing 100 .

[0108] At this time, the recessed portion 120 can receive power with a polarity opposite to that of the power unit 200 through the housing 100. As a result, liquid heat is generated between the rotating body 230 and the surface of the rotating body 230 facing the recessed portion 120 in the front-rear direction. In addition, liquid heat is generated between the shaft 220 and the surface of the shaft 220 facing the recessed portion 120 along the radial direction of the shaft 220, thereby increasing the heat generation of the heat-generating liquid circulator 10.

[0109] In addition, as the position, length, width, shape, etc. of the recessed portion 120 are different, the interval and area between the recessed portion 120 and the rotating body 230 and the shaft 220 that are supplied with power of different polarities will also be different. Therefore, the amount of heat generated by the heat-generating liquid circulator 10 will be different depending on the shape of the recessed portion 120.

[0110] And, if Figure 3 As shown, the opening portion 110 may be formed on a surface of the rotating body 230 facing the recessed portion 120 along the front-rear direction.

[0111] At this time, as the rotating body 230 rotates, the liquid can flow into the interior of the housing 100 through the opening 110 formed on the recessed portion 120. In addition, the rotating body 230 and the recessed portion 120 are respectively connected to power supplies with opposite polarities, so that the liquid between the rotating body 230 and the recessed portion 120 generates heat. As a result, the liquid flows into the inside / outside of the housing 100 through the opening 110 formed on the recessed portion 120, and the flow of the liquid inside / outside the housing 100 causes eddy currents or the heat generated by the liquid inside the housing 100 causes convection, thereby increasing the circulation amount of the liquid inside / outside the housing 100.

[0112] Figure 4FIG. 1 is a perspective view of a heat generating liquid circulator 10 according to the second embodiment of the present invention.

[0113] like Figure 4 As shown, in the housing 100 , at least one of the surface facing the motor 210 in the front-rear direction and the surface facing the rotating body 230 in the front-rear direction is opened.

[0114] At this time, the opening form of the housing 100 is not limited to a specific form, and can be changed according to the purpose of use. In one example, as shown in the figure, the housing 100 can be completely opened on one side to maximize the liquid circulation amount.

[0115] In addition, the larger the opening of the housing 100 is, the greater the amount of liquid circulating in the housing 100 can be. Therefore, considering the amount of liquid circulating required by the housing 100, an appropriate opening and shape of the housing 100 can be selected.

[0116] And, if Figure 4 As shown, the rotating body 230 may include at least one through hole 270 through which liquid can flow.

[0117] As shown in the figure, the cross section of the through hole 270 is circular so that the rotating body 230 is penetrated in the front-to-back direction (specifically, the rotating shaft 231 described below is penetrated). Further, the through hole 270 can be formed on the surface of the motor 210 facing the rotating body 230 in the front-to-back direction. At this time, when the rotation driving force of the power unit 200 is generated, the liquid inside the housing 100 can flow through the through hole 270, which can increase the amount of liquid flow inside / outside the housing 100 formed by the rotation driving force of the power unit 200.

[0118] Figure 5 FIG. 1 shows the positional relationship between the rotating shaft 231 and the extending member 130 in the thermal liquid circulator 10 according to an embodiment of the present invention.

[0119] like Figure 5 As shown, the rotating body 230 may include a rotating shaft 231 and at least one blade 232 .

[0120] The rotating shaft 231 is connected to the shaft 220 and rotates.

[0121] The blades 232 rotate in conjunction with the rotation of the rotating shaft 231 .

[0122] Furthermore, the housing 100 may further include an extension piece 130 .

[0123] The extension member 130 extends from the inner side of the surface of the housing 100 facing the rotation shaft 231 , is powered through the housing 100 , and is inserted on the rotation shaft 231 .

[0124] More specifically, the extension piece 130 extends from the housing 100 and is fed with a power source having the same polarity as the housing 100, and the extension piece 130 is inserted at intervals from the inner wall of the rotating shaft 231, and the rotating shaft 231 is fed with a power source having a polarity opposite to that of the housing 100. Therefore, when viewed from the radial direction of the rotating body 230, the housing 100, the rotating body 230, and the extension piece 130 are alternately arranged in sequence, and the power sources fed into these components have opposite polarities, so as to increase the heat generation of the heat generating liquid circulator 10.

[0125] Furthermore, the liquid is located between the extension member 130 and the inner wall of the rotating shaft 231, and the liquid can further generate heat due to the power supply of opposite polarity passing through the extension member 130 and the rotating shaft 231. Therefore, the liquid located between the extension member 130 and the inner wall of the rotating shaft 231 further generates heat, so that the liquid located inside / outside the housing 100 generates convection, thereby increasing the liquid circulation volume inside / outside the housing 100.

[0126] Figure 6 FIG. 1 is a cross-sectional view of a heat generating liquid circulator 10 including a waterproof portion 140 according to an embodiment of the present invention.

[0127] like Figure 6 As shown, the housing 100 may further include a waterproof portion 140 .

[0128] The waterproof portion 140 is received in the housing 100 and is coupled to the shaft 220 along a radial direction of the shaft 220 to seal the motor 210 .

[0129] More specifically, when viewed from the front-back direction, the opening 110 may not be formed in the region of the housing 100 having the motor 210 based on the waterproof portion 140 .

[0130] Therefore, the space of the housing 100 containing the motor 210 can be sealed by the waterproof part 140, and liquid can flow in. In view of this, when constructing the heat generating liquid circulator 10, the motor 210 whose purpose is not waterproof can be used, and other components that are vulnerable to moisture can be arranged in the space, thereby improving the design flexibility and reducing the manufacturing cost.

[0131] Figure 7 1 is a cross-sectional view of a thermogenic liquid circulator 10 including a first housing 150 and a second housing 160 according to the first embodiment and the third embodiment of the present invention.

[0132] like Figure 7 As shown, the housing 100 may include a first housing 150 and a second housing 160 .

[0133] The power unit 200 may be accommodated inside the first housing 150 .

[0134] The first housing 150 may be accommodated in the second housing 160 .

[0135] Furthermore, a space S for liquid to flow may be formed between the first housing 150 and the second housing 160 .

[0136] At this time, the second housing 160 can receive power, thereby reducing the wear rate of the second housing 160 and preventing accidents such as electric shock or burns when the user touches the second housing 160.

[0137] Figure 7 (a) is a cross-sectional view of a thermostatic liquid circulator 10 including a first housing 150 and a second housing 160 according to an embodiment of the present invention.

[0138] like Figure 7 As shown in (a), the second housing 160 may be formed with a plurality of openings 110 on a surface facing the first housing 150 in the front-rear direction and in the radial direction. At this time, the liquid in the space S may flow through the plurality of openings 110 formed in the second housing 160 in the front-rear direction and in the radial direction, thereby increasing the amount of liquid flow inside / outside the second housing 160.

[0139] Figure 7 (b) is a cross-sectional view of a thermogenic liquid circulator 10 including a first housing 150 and a second housing 160 according to a third embodiment of the present invention.

[0140] like Figure 7 As shown in (b), the second housing 160 may be formed with at least one opening 110 on a pair of opposite sides (front and back) facing the first housing 150 in the front-to-back direction. At this time, the liquid in the space S is surrounded by the first housing 150 and the second housing 160 in all directions except the front-to-back direction, so that the flow of liquid toward the inside / outside of the second housing 160 can be concentrated in the front-to-back direction. Therefore, according to the third embodiment of the present invention, in the space S between the first housing 150 and the second housing 160, the flow of liquid will have a relatively fixed orientation in the limited space S. That is, according to this implementation structure, the flow velocity of the liquid formed in the space S, the temperature of the liquid, etc. are detected, thereby making it easier to detect the performance of the heat generating liquid circulator 10.

[0141] Figure 8 FIG. 2 is a schematic diagram showing the contact between the power supply unit 300 and the shaft 220 in the thermal liquid circulator 10 according to an embodiment of the present invention.

[0142] like Figure 8 As shown, the thermal liquid circulator 10 may further include a power supply unit 300 .

[0143] The power supply unit 300 may include a first cable 310 and a second cable 320 .

[0144] The first cable 310 and the second cable 320 may be supplied with power of opposite polarities.

[0145] Figure 8 (a) is a schematic diagram showing the contact between the power supply unit 300 and the shaft 220 in the thermal liquid circulator 10 according to an embodiment of the present invention.

[0146] like Figure 8 As shown in (a), any one of the first cable 310 and the second cable 320 may be formed with a protrusion 311, 321 having a curved surface at one end.

[0147] Furthermore, the protrusions 311 and 321 are connected to the shaft 220 to supply power.

[0148] More specifically, considering the rotation of the shaft 220, the portion of the protrusions 311 and 321 having the arc surface can be connected to the shaft 220. In one example, the first cable 310 can be formed with a protrusion 311 having an arc surface at one end. In addition, the portion of the protrusion 311 having the arc surface can be connected to the shaft 220 so that the shaft 220 is powered. At this time, the second cable 320 can be powered to the housing 100.

[0149] Alternatively, the second cable 320 may be formed with a protrusion 321 having an arc surface at one end. In addition, the protrusion 321 having the arc surface may be connected to the shaft 220 so that the shaft 220 is powered. In this case, the first cable 310 may be powered to the housing 100.

[0150] And, if Figure 8 As shown in (a), the protrusions 311 and 321 can be inserted into one end of the shaft 220 and connected to the inner wall, but are not limited thereto. In one example, the protrusions 311 and 321 can be connected to one end without being inserted into the shaft 220, or the protrusions 311 and 321 can be connected to the side of the shaft 220.

[0151] As described above, when the portion with the arc surface in the protrusions 311, 321 is connected to the shaft 220 so that the shaft 220 is powered, the protrusions 311, 321 can contact the shaft 220 so as to minimize the impact on the rotation of the shaft 220, thereby reducing the wear of the shaft 220 and the protrusions 311, 321.

[0152] Alternatively, a spherical joint structure (not shown) may be formed at one end of the shaft 220, the spherical joint structure being annular and surrounding the hemispherical portion of the protrusions 311 and 321 to correspond to the protrusions 311 and 321. In this case, the protrusions 311 and 321 may be snap-fitted to surround the annular spherical joint formed at one end of the shaft 220.

[0153] At this time, any one of the first cable 310 and the second cable 320 is snap-connected so that the protrusions 311, 321 are wrapped around the spherical joint formed at one end of the shaft 220. Therefore, its advantage is that even if the shaft 220 is vibrating or moving, the shaft 220 can be stably powered.

[0154] Figure 8 (b) is a schematic diagram showing the contact between the power supply unit 300 and the shaft 220 in the heat generating liquid circulator 10 according to the fourth embodiment of the present invention.

[0155] like Figure 8 As shown in (b), any one of the first cable 310 and the second cable 320 may be provided with a gear portion 312, 322 having a gear formed at one end.

[0156] And, if Figure 8 As shown in (b), the inner surface of the shaft 220 may be provided with a gear coupling portion 221 formed with a gear.

[0157] Furthermore, the gears formed on the gear parts 312 and 332 and the gears formed on the gear combining part 221 may mesh with each other.

[0158] At this time, when the gears formed on the gear parts 312 and 322 are meshed with the gears formed on the gear coupling part 221 on the inner surface of the shaft 220 , power can be supplied from the power supply part 300 to the shaft 220 .

[0159] In one example, the first cable 310 may be provided with a gear portion 312 having a gear formed at one end. When the gear formed on the gear portion 312 is meshed with the gear formed on the gear coupling portion 221 on the inner surface of the shaft 220, power can be supplied from the power supply portion 300 to the shaft 220. At this time, the second cable 320 can supply power to the housing 100.

[0160] Alternatively, the second cable 320 may be provided with a gear portion 322 having a gear formed at one end. When the gear formed on the gear portion 322 is meshed with the gear formed on the gear coupling portion 221 on the inner surface of the shaft 220, power can be supplied from the power supply portion 300 to the shaft 220. At this time, the first cable 310 can supply power to the housing 100.

[0161] According to this embodiment, even if the shaft 220 is vibrating or moving, the shaft 220 can be stably powered.

[0162] Fig. 9 2 is a cross-sectional view of a thermogenic liquid circulator 10 including a linear driving portion 240 according to the first embodiment and the fifth embodiment of the present invention.

[0163] like Fig. 9 As shown, the power unit 200 may further include a linear drive unit 240 .

[0164] The linear driving unit 240 is supported by the inner surface of the housing 100 to move the power unit 200 in at least one direction of a front-rear direction and a radial direction.

[0165] Fig. 9 (a) is a cross-sectional view of a thermal liquid circulator 10 including a linear driving portion 240 and a buffer member 400 according to an embodiment of the present invention.

[0166] like Fig. 9 As shown in (a), the linear driving part 240 may be supported by the surface of the motor 210 facing the housing 100 in the front-rear direction, and in this case, the linear driving part 240 may be formed as at least one linear actuator, and the at least one linear actuator may move the motor 210 in the front-rear direction. That is, one end of the linear driving part 240 is coupled to the surface of the motor 210 facing the housing 100 in the front-rear direction, and the other end of the linear driving part 240 may be coupled to the motor 210.

[0167] Furthermore, in the present invention, the amount of heat generated can be changed according to the distance between the housing 100 and the power unit 200, and the housing 100 is supplied with power of different polarities. In addition, in the present embodiment, the power unit 200 is moved by the driving of the linear driving unit 240, the distance between the housing 100 and the power unit 200 is adjusted, and the amount of heat generated by the thermogenic liquid circulator 10 is adjusted. Thus, even if the installation position and installation angle of the thermogenic liquid circulator 10 are changed at the installation site of the thermogenic liquid circulator 10, the power unit 200 can be moved by the driving of the linear driving unit 240, so as to form the optimal distance between the housing 100 and the power unit 200 in consideration of the changed installation position of the thermogenic liquid circulator 10, thereby increasing the amount of heat generated by the thermogenic liquid circulator 10.

[0168] Furthermore, when the power unit 200 is moved by the driving of the linear driving unit 240, the liquid flow inside / outside the housing 100 can be generated automatically, thereby improving the liquid circulation inside / outside the housing 100. When the rotation driving force generated by the rotating body 230 of the power unit 200 is limited by the above process, the linear driving unit 240 can realize the linear movement of the power unit 200 in the front-rear direction, so that the liquid inside / outside the housing 100 flows, thereby minimizing the performance degradation of the hot liquid circulator 10.

[0169] And, if Fig. 9 As shown in (a), the thermal liquid circulator 10 may further include at least one buffer 400 .

[0170] The buffer member 400 may include corners on a surface facing the rotating body 230 of the housing 100 in the front-rear direction.

[0171] In addition, the buffer member 400 can prevent the power unit 200 from colliding with the housing 100 by moving according to the rotational driving force or vibration of the power unit 200 or by linearly moving according to the driving of the linear driving unit 240 .

[0172] Furthermore, the buffer member 400 is made of an elastic material, such as rubber, and as shown in the figure, can have a plurality of polyhedral convex shapes, but is not limited thereto.

[0173] Fig. 9 (b) is a cross-sectional view of a heat generating liquid circulator 10 including a linear driving portion 240 according to a fifth embodiment of the present invention.

[0174] like Fig. 9As shown in (b), the linear driving part 240 may be supported by the surface of the motor 210 facing the housing 100 in the radial direction. In this case, the linear driving part 240 may be formed as at least one linear actuator, and the at least one linear actuator may move the motor 210 in the radial direction of the housing 100. That is, one end of the linear driving part 240 is coupled to the surface of the motor 210 facing the housing 100 in the radial direction of the housing 100, and the other end of the linear driving part 240 may be coupled to the motor 210.

[0175] Furthermore, when the power unit 200 is moved by the driving of the linear driving unit 240 , the flow of the liquid inside / outside the housing 100 can be automatically generated, thereby improving the circulation of the liquid inside / outside the housing 100 .

[0176] Fig.10 2 is a cross-sectional view of a heat generating liquid circulator 10 including a crankshaft drive device 250 according to the sixth and seventh embodiments of the present invention.

[0177] like Fig.10 As shown, according to the sixth and seventh embodiments of the present invention, the heat generating liquid circulator 10 may include a guide member 170 , a support member 180 , and a crankshaft driving device 250 .

[0178] The guide member 170 can suppress radial movement of the housing 100 of the motor 210 and guide the front-to-back movement of the motor 210. More specifically, the guide member 170 has a front-to-back length corresponding to the front-to-back movable range of the motor 210 according to the driving of the crankshaft driving device 250, and at least a portion of the guide member 170 is radially connected to the motor 210, thereby suppressing radial movement of the motor 210 and guiding the front-to-back movement of the motor 210.

[0179] The support member 180 may support the guide member 170 in a radial direction of the housing 100 . More specifically, one end of the support member 180 may be coupled to a surface of the guide member 170 radially facing the housing 100 , and the other end may be coupled to the guide member 170 .

[0180] The crankshaft driving device 250 is supported by the inner surface of the housing 100 and can move the power unit 200 in the front-rear direction.

[0181] More specifically, the crankshaft driving device 250 may include a flywheel 251 , a crankshaft 252 , a crank arm 253 , a connecting rod 254 and a connecting member 255 .

[0182] The flywheel 251 stores rotational energy generated by the driving of the crankshaft driving device 250 to prevent a sudden speed change of the crankshaft driving device 250 .

[0183] The crankshaft 252 is connected to an independent servo motor (not shown) with a direction perpendicular to the front-rear direction as an axis, receives power and rotates.

[0184] The crank arm 253 can be connected to the crankshaft 252 and rotate.

[0185] One end of the connecting rod 254 is connected to the crank arm 253, and the other end can be combined with the connecting piece 255. At this time, the connecting rod 254 is connected to the crank arm 253 and rotates, and the connecting rod 254 can transmit the power generated by the rotation of the crank arm 253 to the connecting piece 255.

[0186] One end of the connecting member 255 is connected to the connecting rod 254, and the other end can be combined with the motor 210. At this time, the connecting member 255 can move the motor 210 in the front and rear directions through the rotation of the crank arm 253.

[0187] That is, the crankshaft driving device 250 can move the power unit 200 in the front-rear direction, thereby adjusting the distance between the housing 100 and the power unit 200 and adjusting the heat generated by the heat-generating liquid circulator 10 .

[0188] Furthermore, when the power unit 200 is moved by the driving of the crankshaft driving device 250 , the flow of the liquid inside / outside the housing 100 can be automatically generated, thereby improving the circulation of the liquid inside / outside the housing 100 .

[0189] Fig.10 (a) is a cross-sectional view of a heat generating liquid circulator 10 including a crankshaft driving device 250 according to a sixth embodiment of the present invention.

[0190] like Fig.10 As shown in (a), the power unit 200 may further include an insulating member 260 .

[0191] The insulating member 260 may be formed as an insulator to suppress the flow of current.

[0192] Furthermore, the insulating member 260 may be formed in a disk shape with a groove formed at the center so as to be spaced apart from the shaft 220 by a given distance in the radial direction of the shaft 220 and spaced apart from the housing 100 by a given distance in the radial direction of the housing 100. At this time, at least a portion of the insulating member 260 is coupled to the surface of the motor 210 facing the rotating body 230. Therefore, when viewed from the front-back direction, most of the heating liquid between the housing 100 and the rotating body 230 circulates in the region of the housing 100 having the rotating body 230 and the outside of the housing 100 adjacent thereto, based on the insulating member 260, and the housing 100 is supplied with power supplies of different polarities.

[0193] That is, when viewed from the front-to-back direction, most of the heat generation of the heat-generating liquid circulator 10 and the circulation of the liquid inside / outside the housing 100 are performed based on the insulating member 260 in the area of ​​the housing 100 having the rotating body 230 and the outside of the housing 100 adjacent thereto. Furthermore, when viewed from the front-to-back direction, the motor 210, the shaft 220, and the crankshaft drive device 250 are located based on the insulating member 260 in the area of ​​the housing 100 having the motor 210, so that the speed of wear caused by the heated liquid inside the housing 100 can be reduced.

[0194] Furthermore, when the power unit 200 is moved by the crankshaft driving device 250, the insulating member 260 coupled to the rotating body 230 may move, causing the liquid inside / outside the housing 100 to flow. Therefore, the insulating member 260 may improve the circulation of the liquid inside / outside the housing 100.

[0195] Fig.10 (b) is a cross-sectional view of a heat generating liquid circulator 10 including a crankshaft driving device 250 according to a seventh embodiment of the present invention.

[0196] like Fig.10 As shown in (b), the housing 100 may further include an insulating portion 190 .

[0197] The insulating part 190 may be formed as an insulator to suppress the flow of current.

[0198] Furthermore, the insulating portion 190 is spaced from the shaft 220 in the radial direction of the shaft 220 and is on the surface of the shaft 220 facing the housing 100 in the radial direction. At this time, when viewed from the front-to-back direction, the end of the insulating portion 190 can be located in the area of ​​the housing 100 in the direction of the motor 210 based on the rotating body 230, so as not to interfere with the movable range of the rotating body 230 in the front-to-back direction driven by the crankshaft drive device 250. Therefore, when viewed from the front-to-back direction, most of the heating liquid located between the housing 100 and the rotating body 230 circulates in the area of ​​the housing 100 with the rotating body 230 and the outside of the housing 100 adjacent thereto based on the insulating portion 190, and the housing 100 is supplied with power supplies of different polarities.

[0199] That is, when viewed from the front-to-back direction, most of the heat generation of the heat-generating liquid circulator 10 and the circulation of the liquid inside / outside the housing 100 are performed based on the insulating portion 190 in the region of the housing 100 having the rotating body 230 and the outside of the housing 100 adjacent thereto. Furthermore, when viewed from the front-to-back direction, the motor 210, the shaft 220, and the crankshaft drive device 250 are located based on the insulating portion 190 in the region of the housing 100 having the motor 210, so that the speed of wear caused by the heated liquid can be reduced.

[0200] Fig.11 The figure shows a rotating body 230 of a heat generating liquid circulator 10 including a blade control unit 233 according to an embodiment of the present invention.

[0201] like Fig.11 As shown, the rotating body 230 may further include a blade control unit 233 .

[0202] Furthermore, the blade control unit 233 can adjust at least one of the rotation angle of the blade 232 radially opposite to the shaft 231 and the rotation angle of the blade 232 radially opposite to the inner surface of the housing 100 facing the shaft 231.

[0203] More specifically, the blade control unit 233 may include a first blade control unit 233 a and a second blade control unit 233 b .

[0204] The first blade control unit 233a may be formed in a motor form to rotate the blade 232 relative to the radial direction of the rotation shaft 231. Therefore, the rotation direction of the blade 232 may be the same as the rotation direction of the motor of the first blade control unit 233a.

[0205] That is, the blade control unit 233 may adjust the rotation of the motor of the first blade control unit 233 a to adjust the rotation angle of the blades 232 radially opposite to the rotation shaft 231 .

[0206] The second blade control unit 233 b may include a guide rail 2331 , a rail coupling member 2332 , and a linear driving device 2333 .

[0207] At this time, the first blade control part 233a is rotatably combined with the rotating shaft 231 so as to rotate relative to the side surface of the rotating shaft 231, and the side surface of the rotating shaft 231 faces the inner surface of the housing 100 in the radial direction of the rotating shaft 231. At this time, when an external force is applied to the first blade control part 233a through the second blade control part 233b, the first blade control part 233a can rotate relative to the side surface of the rotating shaft 231 in the state of being combined with the rotating shaft 231, and the side surface of the rotating shaft 231 faces the inner surface of the housing 100 in the radial direction of the rotating shaft 231.

[0208] The guide rail 2331 may be coupled to the inner surface of the rotating shaft 231 along a radial direction of the rotating shaft 231 .

[0209] One end of the track coupling member 2332 is coupled to the linear driving device 2333 , and the other end is coupled to the guide rail 2331 , and moves along the guide rail 2331 .

[0210] The linear drive device 2333 may be formed in the form of a linear actuator, and may perform linear motion by extending and contracting. In addition, one end of the linear drive device 2333 is combined with the first blade control part 233a, and the other end may be combined with the track coupling member 2332. The linear drive device 2333 may be driven by a separate servo motor (not shown).

[0211] At this time, if the linear driving device 2333 is extended, the track coupling member 2332 can move along the guide rail 2331 toward the radial direction of the rotating shaft 231. In addition, as the track coupling member 2332 moves, the linear driving device 2333 can rotate relative to the side surface of the rotating shaft 231, and the side surface of the rotating shaft 231 faces the inner surface of the housing 100 in the radial direction of the rotating shaft 231. In addition, the first blade control part 233a coupled to the linear driving device 2333 and the blade 232 coupled to the first blade control part 233a can rotate as the linear driving device 2333 rotates.

[0212] Alternatively, when the linear drive device 2333 is reduced, the track coupling member 2332 may move along the guide rail 2331 in a direction opposite to the extension direction of the linear drive device 2333. Furthermore, the blade 232 may rotate in a direction opposite to the extension direction of the linear drive device 2333.

[0213] That is, the blade control unit 233 can adjust the rotation angle of the blade 232 relative to the side of the rotating shaft 231 by adjusting the extension and contraction of the linear drive device 2333, and the side of the rotating shaft 231 faces the inner surface of the housing 100 in the radial direction of the rotating shaft 231.

[0214] Furthermore, the blades 232 may be curved relative to the radial direction of the rotating shaft 231. Therefore, when the rotation angle of the blades 232 changes, the amount and direction of the liquid pushed out by the rotating body 230 of the thermal liquid circulator 10 may change.

[0215] Furthermore, the blades 232 and the housing 100 can be connected to power supplies with opposite polarities. Thus, the heat generation of the heat generating liquid circulator 10 will change according to the distance between the blades 232 and the housing 100 and the area facing each other. At this time, the blades 232 can be curved relative to the radial direction of the rotating shaft 231, and the radial direction of the rotating shaft 231 is the same as the radial direction of the housing 100. Therefore, when the rotation angle of the blades 232 changes, the distance between the blades 232 and the housing 100 and the area facing each other will change.

[0216] Therefore, the rotation angle of the blade 232 can be adjusted by the blade control unit 233, thereby adjusting the heat generation amount, liquid flow amount, and liquid flow direction of the heat generating liquid circulator 10.

[0217] Fig.12 FIG. 5 is a cross-sectional view of a heat generating liquid circulator 10 including a charging unit 500 according to an embodiment of the present invention.

[0218] like Fig.12 As shown, the thermal liquid circulator 10 may further include a charging unit 500 .

[0219] The charging unit 500 is accommodated in the housing 100 , and a coil is formed in the charging unit 500 to generate an induced current. Furthermore, the charging unit 500 is connected to the power unit 200 , so as to transmit the generated induced current to the power unit 200 .

[0220] More specifically, in the charging unit 500, in order to generate an induced current externally, when current is passed through a transmission coil corresponding to a coil formed inside the charging unit 500, the transmission coil will generate a magnetic field, and the coil inside the charging unit 500 corresponding to the transmission coil will be affected by the magnetic field and generate electrical induction, thereby generating current using a magnetic induction method to generate an induced current.

[0221] That is, the thermal liquid circulator 10 can be charged with current wirelessly through the charging unit 500, so it is not necessary to have an independent charging data cable for wired charging, and problems such as current charging limitation or current leakage caused by breakage or damage of the charging data cable can be prevented.

[0222] At this time, considering the distance from the external transmission coil, the charging unit 500 may be provided on the inner surface of the housing 100. Alternatively, considering the current transmission to the power unit 200, the charging unit 500 may be adjacent to the power unit 200 or accommodated inside the power unit 200.

[0223] Figures 13 to 151 is a cross-sectional view of a heat generating liquid circulator 10 according to the eighth to tenth embodiments of the present invention.

[0224] like Figures 13 to 15 As shown, the thermogenic liquid circulator 10 may include a plurality of power units 200 .

[0225] According to this implementation structure, the heat generating liquid circulator 10 may include a plurality of power units 200 to increase the amount of liquid flow inside / outside the housing 100 .

[0226] Furthermore, the power unit 200 can be connected to a power source with a polarity opposite to that of the housing 100. Furthermore, the thermogenic liquid circulator 10 can include a plurality of power units 200, which can increase the area of ​​the power unit 200 connected to the power source compared to when a single power unit 200 is included. Therefore, in the thermogenic liquid circulator 10, the space between the power unit 200 and the housing 100 can be enlarged to increase the amount of heat generated, and the space is used to implement liquid heat generation.

[0227] like Fig.13 As shown, the multiple power units 200 can be arranged in the same direction.

[0228] More specifically, the heat generating liquid circulator 10 may arrange the plurality of power units 200 in the same direction, thereby increasing the liquid flow speed inside / outside the housing 100 .

[0229] like Fig.14 As shown, the plurality of power units 200 may be arranged in pairs, with the motors 210 arranged face to face.

[0230] More specifically, the thermodynamic liquid circulator 10 can pair the multiple power units 200 and configure the motors 210 face to face, so that the multiple rotating bodies 230 included in the multiple power units 200 are adjacent to the casing 100 to increase the heat generation of the thermodynamic liquid circulator 10.

[0231] like Fig.15 As shown, the plurality of power units 200 may be in pairs, with the rotating bodies 230 arranged face to face, and the directions of the blades 232 of the two face to face power units 200 may be opposite.

[0232] In addition, in the heat generating liquid circulator 10, when the power parts 200 of the same structure are arranged face to face, the shape and rotation direction of the rotating body 230 included in the power part 200 are the same, so that the liquid flows in opposite directions.

[0233] To solve the above problem, the heat generating liquid circulator 10 can make the blades 232 of the paired and facing power parts 200 in opposite directions, so that the liquid flows in the same direction through the paired and facing power parts 200. Thus, the liquid flow speed inside / outside the housing 100 can be increased.

[0234] Alternatively, the heat generating liquid circulator 10 rotates the motors 210 of the paired and facing power parts 200 in opposite directions, so that the liquid flows in the same direction through the paired and facing power parts 200. Thus, the liquid flow speed inside / outside the housing 100 can be increased.

[0235] Fig.16 FIG. 1 is a cross-sectional view of a heat generating liquid circulator 1010 according to an eleventh embodiment of the present invention.

[0236] like Fig.16 As shown, according to another embodiment of the present invention, a heat generating liquid circulator 1010 may include a housing 1100 , a power unit 1200 , and a heat generating unit 1300 .

[0237] The power unit 1200 may generate a rotational driving force for circulating the liquid.

[0238] The heat generating part 1300 may generate heat.

[0239] The housing 1100 may be formed with at least one opening 1110 through which liquid can flow. Also, the housing 1100 may contain the power unit 1200 and the heat generating unit 1300 .

[0240] That is, as described in the heat generating liquid circulator 10 according to one embodiment of the present invention, the heat generating liquid circulator 1010 does not generate heat for the liquid by supplying power with opposite polarities to the casing 100 and the power unit 200, but utilizes the heat generating unit 1300 included in the heat generating liquid circulator 1010 to generate heat for the liquid.

[0241] Therefore, the heat generating liquid circulator 1010 does not supply power to the housing 1100 and the power unit 1200, thereby reducing the wear rate of the housing 1100 and the power unit 1200. In addition, the housing 1100 is not supplied with power, thereby preventing accidents such as electric shock or burns when a user touches the housing 1100.

[0242] The power unit 1200 may include a motor 1210 , a shaft 1220 , and a rotating body 1230 .

[0243] The shaft 1220) is connected to the motor 1210 to receive power.

[0244] The rotating body 1230 is connected to the shaft 122 and rotates.

[0245] The heat generating unit 1300 can generate heat by using an electrode heat generating body with different polarity power, but is not limited thereto. In one example, the heat generating unit 1300 can generate heat by using a resistor or another fuel to generate heat for the liquid.

[0246] Furthermore, as shown in the figure, the heat generating unit 1300 can be arranged facing the motor 1210 in the front-rear direction, but the present invention is not limited thereto. In one example, the heat generating unit 1300 can be arranged facing the rotating body 1230 in the front-rear direction, or can be arranged offset from the power unit 1200 in the up-down direction.

[0247] Furthermore, the heat generating unit 1300 can adjust whether to generate heat and the amount of heat generated. At this time, the heat generating unit 1300 can have a built-in printed circuit board (PCB) to adjust whether to generate heat and the amount of heat generated.

[0248] Furthermore, the heat generating liquid circulator 1010 may further include a plurality of heat generating parts 1300 for increasing the heat generating area and the heat generating amount. At this time, the heat generating liquid circulator 1010 may enable the plurality of heat generating parts 1300 to generate heat simultaneously and quickly heat the liquid inside, or may enable the plurality of heat generating parts 1300 to generate heat in stages to adjust the heat generating amount.

[0249] Furthermore, the heat generating liquid circulator 1010 may include: a configuration corresponding to the configuration of the heat generating liquid circulator 10 in the embodiment of the present invention. In one example, the heat generating liquid circulator 1010 may include: a configuration corresponding to the configuration of the heat generating liquid circulator 10 in the embodiment of the present invention, that is, a waterproof part, a first housing, a second housing, a rotating shaft, blades, a blade control part, a linear driving part, a buffer, and a charging part.

[0250] Figures 17 to 19 10 is a cross-sectional view of a heat generating liquid circulator 1010 according to twelfth to fourteenth embodiments of the present invention.

[0251] like Figures 17 to 19 As shown, the thermogenic liquid circulator 1010 may include a plurality of power units 1200 .

[0252] Therefore, the thermogenic liquid circulator 1010 may include a plurality of power units 1200 to increase the amount of liquid flow inside / outside the housing 1100 .

[0253] Furthermore, the plurality of power units 1200 may be arranged in the same direction or in pairs facing each other.

[0254] At this time, if Fig.17 As shown, the heat generating liquid circulator 1010 can configure the multiple power units 1200 in the same direction to increase the flow rate of the liquid.

[0255] Or, if Fig.18 As shown, the heat generating liquid circulator 1010 can pair the multiple power units 1200 and configure the motors 1210 face to face, thereby dispersing the liquid flow direction inside / outside the casing 1100 and increasing the liquid flow amount inside / outside the casing 1100.

[0256] Or, if Fig.19 As shown, the heat generating liquid circulator 1010 can make the multiple power units 1200 paired, and the rotating bodies 1230 are arranged face to face, and the directions of the blades of the two power units 1200 facing each other can be opposite). Through the above structure, the flow speed of the liquid can be maximized between the rotating bodies 1230 of the paired and face-to-face power units 1200. Therefore, the heat generating liquid circulator 1010 can also increase the flow speed of the liquid. The heat generating unit 1300 is arranged between the rotating bodies 1230 of the paired and face-to-face power units 1200, so that the heated liquid can be quickly circulated inside / outside the casing 1100.

[0257] At this time, if Figures 17 to 19 As shown, the heat generating part 1300 may be located at the center of the housing 1100, but is not limited thereto. In one example, the heat generating part 1300 faces the rotating body 1230 or the motor 1210 included in any power part 1200 in the front-rear direction, so that the heated liquid is quickly circulated inside / outside the housing 1100.

[0258] As described above, although the present invention is described through limited embodiments and drawings, the present invention is not limited thereto. Of course, a person skilled in the art in the technical field to which the present invention belongs can implement various modifications and variations within the technical concept of the present invention and the equivalent scope of the appended claims.
