Description

Technical Field

[0001] The present invention relates to the technical field of heating devices, and more specifically, to a heating device for saunas. Background Art

[0002] The water for sauna bathing is usually heated by a heat pump. A heat pump is a device that can transfer the heat energy of a low-temperature heat source to a high-temperature heat source. By absorbing the low-grade heat energy in the air and using a small amount of electric energy to convert it into high-grade heat energy, and then transporting the heat energy to the place where heating is required.

[0003] However, when in use, the heat pump will pass through a filter screen to filter impurities, suspended substances and particulate matters in the air to prevent impurities from directly entering the system and damaging the internal equipment of the device, affecting the normal operation and service life of the device. When a large amount of dust is adsorbed on the filter screen, it will cause the filter screen to become clogged, reducing air circulation and affecting the heating capacity of the heat pump, resulting in poor temperature adjustment effect in the sauna area; and the heat pump is usually installed outdoors. When the sun shines directly on the heat pump, the electronic control components heat up severely during the operation of the unit. After being directly exposed to the sun for a long time, the main electrical control components age rapidly, and at the same time, the temperature inside the heat pump will rise, interfering with its normal operating temperature range, and further affecting its heat exchange efficiency; at the same time, the compressor equipment is installed inside the heat pump.

[0036] Specifically, as Figure 9 , Figure 10 and Figure 11As shown, a guide block 607 is fixedly connected to the sunshade 606. The guide block 607 is slidably connected to the mounting seat 605. A second hydraulic rod 613 is installed on the mounting seat 605. The telescopic end of the second hydraulic rod 613 is fixedly connected to a fixing strip 614. The fixing strip 614 is fixedly connected to the sunshade 606. A second motor 615 is installed at the bottom of the fixing seat 601. The mounting shaft 602 is fixedly connected to the output shaft of the second motor 615. During daily use, by starting the second motor 615, when the output shaft of the second motor 615 rotates, it drives the mounting shaft 602 to rotate. The mounting shaft 602 drives the fixing seat 601 to rotate. The rotating seat 603 drives the mounting seat 605 to rotate through the first connecting shaft 604. The mounting seat 605 adjusts the sunshade 606. Then, by starting the first hydraulic rod 610, when the telescopic end of the first hydraulic rod 610 extends, it adjusts the angle of the sunshade 606. When the first hydraulic rod 610 operates, the connecting block 609 and the second connecting shaft 608 rotate, and at the same time, the second fixed shaft 612 and the fixing block 611 rotate. At this time, by starting the second hydraulic rod 613, the telescopic end of the second hydraulic rod 613 drives the sunshade 606 to move through the fixing strip 614. The sunshade 606 drives the guide block 607 to slide with the mounting seat 605. At this time, the position of the sunshade 606 is adjusted, and then the angle of the sunshade 606 is adjusted by the first hydraulic rod 610 to shade the heat pump body 1 according to the sun's irradiation angle, preventing the heat pump body 1 from being exposed to strong sunlight, which may cause the temperature inside the heat pump body 1 to rise, thus interfering with its normal operating temperature range and further affecting its heat exchange efficiency.

[0037] Specifically, as Figure 2 , Figure 3 and Figure 4As shown, the sliding seat 201 is threadedly connected to the first lead screw 202. A slot 203 is provided on the first lead screw 202. A connecting seat 204 is fixedly connected to the bottom of the heat pump body 1. A rotating shaft 205 is rotatably connected to the connecting seat 204. A pin 206 that is slidably connected to the rotating shaft 205 and is used in cooperation with the slot 203 is provided. An installation block 207 is fixedly connected to the rotating shaft 205. A clamping block 208 is slidably connected to the installation block 207. Two card slots 209 that are used in cooperation with the clamping block 208 are provided on the pin 206. The clamping block 208 is engaged with one of the card slots 209. A second lead screw 210 is rotatably connected to the installation block 207. The clamping block 208 is threadedly connected to the second lead screw 210. A first pulley 213 is fixedly connected to the rotating shaft 205. A rotating rod 211 is fixedly connected to the second lead screw 210. A pulling block 212 is fixedly connected to the pin 206. When it is necessary to install and repair equipment such as the compressor 301, the pin 206 is inserted into the slot 203 in the first lead screw 202. Then, the second lead screw 210 is rotated by the rotating rod 211. The second lead screw 210 threadedly drives the clamping block 208 to slide within the installation block 207 and engage with the card slot 209 on the pin 206. At this time, the docking between the pin 206 and the first lead screw 202 is completed. Then, by starting the first motor 412, the first motor 412 drives the third pulley 410 to rotate through one of the third lead screws 402. The third pulley 410 drives the first pulley 213 to rotate through a belt. When the first pulley 213 rotates, it drives the rotating shaft 205 to rotate. When the rotating shaft 205 rotates, it drives the first lead screw 202 to rotate through the pin 206. When the first lead screw 202 rotates, it threadedly drives the sliding seat 201 to slide outwards, so that the sliding seat 201 drives equipment such as the compressor 301 and the separator 302 to slide out of the heat pump body 1 for maintenance. By driving equipment such as the compressor 301 and the separator 302 to slide out of the heat pump body 1 by the sliding seat 201, the maintenance space can be increased, which is convenient for quick maintenance and avoids the increase in the maintenance difficulty of equipment such as the compressor 301 due to the small internal space, the compact internal structure and the limited space.

[0038] Specifically, such as Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8As shown, the cleaning structure 4 includes four connecting plates 401 fixedly connected to the heat pump body 1 and a third lead screw 402 rotatably connected between every two of the connecting plates 401. Two guiding frames 408 are fixedly connected to the heat pump body 1. A slider 403 is slidably connected inside the guiding frame 408. The slider 403 is threadedly connected to the third lead screw 402. A first fixed shaft 404 is rotatably connected to the slider 403. A cleaning brush 405 is installed on the first fixed shaft 404 through an installation structure 5. A gear 406 is fixedly connected to the first fixed shaft 404. A rack 407 is fixedly connected inside the guiding frame 408. The gear 406 meshes with the rack 407. A second pulley 409 is fixedly connected to the third lead screw 402. The two second pulleys 409 are driven by a belt. A third pulley 410 is fixedly connected to one of the third lead screws 402. The third pulley 410 is driven by a belt in cooperation with the first pulley 213. An installation plate 411 is fixedly connected to one of the connecting plates 401. A first motor 412 is installed on the installation plate 411. The output shaft of the first motor 412 is fixedly connected to one of the third lead screws 402. The installation structure 5 includes an iron ring 501 fixedly connected to the first fixed shaft 404 and a magnetic ring 502 fixedly connected to the cleaning brush 405. The magnetic ring 502 is adsorbed below the iron ring 501. A positioning strip 503 is fixedly connected to the first fixed shaft 404. The cleaning brush 405 is slidably connected to the positioning strip 503. A knob 504 is threadedly connected to the first fixed shaft 404. A fixing column 505 is fixedly connected to the knob 504. The fixing column 505 abuts against the cleaning brush 405. A ball 506 is rotatably connected inside the fixing column 505. The ball 506 is in rolling connection with the cleaning brush 405. When cleaning the filter net 8 on the installation frame 7, by starting the first motor 412, when the output shaft of the first motor 412 rotates, it drives one of the third lead screws 402 to rotate. The third lead screw 402 drives the other third lead screw 402 to rotate through the cooperation of the two second pulleys 409 and the belt. When the third lead screw 402 rotates, it threadedly drives the slider 403 to slide inside the guiding frame 408. When the slider 403 slides, it drives the first fixed shaft 404 to move. The first fixed shaft 404 drives the gear 406 to mesh with the rack 407, causing the gear 406 to rotate. When the gear 406 rotates, it drives the first fixed shaft 404 to rotate. The first fixed shaft 404 drives the cleaning brush 405 to rotate. When the cleaning brush 405 moves left and right and rotates, it cleans the dust on the filter net 8. By cleaning the dust on the filter net 8 with the cleaning brush 405, it avoids the dust accumulating on the filter net 8, preventing the air from effectively passing through the filter net 8, and thus avoiding affecting the heating effect of the heat pump body 1. When it is necessary to replace the cleaning brush 405, by inserting the cleaning brush 405 in cooperation with the positioning strip 503 on the first fixed shaft 404,When the magnetic ring 502 on the cleaning brush 405 approaches the iron ring 501, the magnetic ring 502 will be adsorbed at the bottom of the iron ring 501 at this time. Then, through the threaded cooperation between the knob 504 and the first fixed shaft 404, the fixed column 505 drives the ball 506. The friction is reduced by the ball 506. At the same time, the fixed column 505 continuously drives the ball 506 to tightly press against the cleaning brush 405 upward, making the stability between the cleaning brush 405 and the first fixed shaft 404 better.

[0039] When the present invention is in use, outdoor air undergoes heat exchange through the evaporator 305, and the air with reduced temperature is discharged from the system by the axial flow fan 306. At the same time, the working medium inside the evaporator 305 absorbs heat and vaporizes and is sucked into the compressor 301. The compressor 301 consumes electrical energy to compress the low-temperature and low-pressure gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant. This process increases the temperature and pressure of the refrigerant, thereby enabling it to have higher thermal energy. After the compressor 301, the high-temperature and high-pressure gaseous refrigerant enters the separator 302. The function of the separator 302 is to ensure that the liquid and gas in the refrigerant are separated before it enters the next-stage heat exchanger to ensure the heat exchange efficiency. The refrigerant then enters the high-efficiency tank 303, where it undergoes heat exchange with water. Since the temperature of the refrigerant is very high, it can transfer heat to the water, causing the water temperature to rise. The heated water will enter the place required for the sauna from the pipeline;

[0040] When cleaning the filter screen 8 on the installation frame 7, by starting the first motor 412, when the output shaft of the first motor 412 rotates, it drives one of the third lead screws 402 to rotate. The third lead screw 402 drives the other third lead screw 402 to rotate through the cooperation of two second belt pulleys 409 and the belt. When the third lead screw 402 rotates, it thread-drives the slider 403 to slide in the guide frame 408. When the slider 403 slides, it drives the first fixed shaft 404 to move. The first fixed shaft 404 drives the gear 406 to engage with the rack 407, causing the gear 406 to rotate. When the gear 406 rotates, it drives the first fixed shaft 404 to rotate. The first fixed shaft 404 drives the cleaning brush 405 to rotate. When the cleaning brush 405 moves left and right and rotates, it cleans the dust on the filter screen 8. By cleaning the dust on the filter screen 8 with the cleaning brush 405, it avoids the accumulation of dust on the filter screen 8, which prevents air from effectively passing through the filter screen 8, thus avoiding affecting the heating effect of the heat pump body 1. When the cleaning brush 405 needs to be replaced, the cleaning brush 405 is inserted and matched with the positioning strip 503 on the first fixed shaft 404. When the magnetic ring 502 on the cleaning brush 405 approaches the iron ring 501, at this time, the magnetic ring 502 will be adsorbed at the bottom of the iron ring 501. Then, through the threaded cooperation of the knob 504 and the first fixed shaft 404, the fixed column 505 drives the ball 506. By the ball 506, the friction force is reduced. At the same time, the fixed column 505 continuously drives the ball 506 to press tightly against the cleaning brush 405 upward, making the stability between the cleaning brush 405 and the first fixed shaft 404 better;

[0041] When installing and overhauling equipment such as the compressor 301, the pin 206 is inserted into the slot 203 in the first lead screw 202, and then the second lead screw 210 is rotated by the rotating rod 211. The second lead screw 210 thread-drives the block 208 to slide in the mounting block 207 and engage with the slot 209 on the pin 206. At this time, the docking between the pin 206 and the first lead screw 202 is completed. Then, by continuing to start the first motor 412, the first motor 412 drives the third belt pulley 410 to rotate through one of the third lead screws 402. The third belt pulley 410 drives the first belt pulley 213 to rotate through the belt. When the first belt pulley 213 rotates, it drives the rotating shaft 205 to rotate. When the rotating shaft 205 rotates, it drives the first lead screw 202 to rotate through the pin 206. When the first lead screw 202 rotates, it thread-drives the slide base 201 to slide outwards, causing the slide base 201 to drive equipment such as the compressor 301 and the separator 302 to slide out of the heat pump body 1 for overhaul. By driving equipment such as the compressor 301 and the separator 302 to slide out of the heat pump body 1 by the slide base 201, it can increase the overhaul space, facilitate quick overhaul, and avoid the increase in overhaul difficulty caused by the compact internal structure and limited space of equipment such as the compressor 301 due to the small internal space;

[0042] During daily use, the second motor 615 can be started. When the output shaft of the second motor 615 rotates, it drives the mounting shaft 602 to rotate. The mounting shaft 602 drives the fixed seat 601 to rotate. The rotating seat 603 drives the mounting seat 605 to rotate through the first connecting shaft 604. The mounting seat 605 adjusts the sunshade 606. Then, the first hydraulic rod 610 can be started. When the telescopic end of the first hydraulic rod 610 extends, it adjusts the angle of the sunshade 606. When the first hydraulic rod 610 operates, the connecting block 609 rotates with the second connecting shaft 608, and at the same time, the second fixed shaft 612 rotates with the fixed block 611. At this time, the second hydraulic rod 613 can be started. The telescopic end of the second hydraulic rod 613 drives the sunshade 606 to move through the fixed strip 614. The sunshade 606 drives the guide block 607 to slide with the mounting seat 605. At this time, the position of the sunshade 606 is adjusted, and then the angle of the sunshade 606 is adjusted by the first hydraulic rod 610, so as to shade the heat pump body 1 according to the sun's irradiation angle, and avoid the temperature inside the heat pump body 1 from rising due to the heat pump body 1 being exposed to strong sunlight, thus interfering with its normal operating temperature range and further affecting its heat exchange efficiency.
