[0045] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below in combination with the drawings.

[0046] In order to solve the problem that the existing central air conditioner and split air conditioner rely on fan forced circulation of air, cold and hot air is directly blown to the human body, the blowing feeling and temperature are uneven, the high-speed airflow takes away the heat on the surface of the human body, and cold feeling, headache and joint discomfort are caused, the application provides an air conditioner refrigeration and heating device based on vertical enhanced convection heat exchange of capillary pipes, which comprises: a protective cylinder 200, a cylinder body 500, a heat exchange mechanism 800 and a circulating pipeline 900;

[0047] As shown in Figure 1 and Figure 2 , the protective cylinder 200 is the external protective shell of the air conditioner refrigeration and heating device of the application, which is used for protecting the internal structure, at the same time, the protective cylinder 200 also has the heat insulation effect, which separates the heat exchange mechanism 800 from the indoor environment, avoiding the problem that the heat exchange mechanism 800 is directly exposed to the outside and may be polluted by dust or other impurities in the air;

[0048] The cylinder body 500 is placed in the inside of the protective cylinder 200, and the heat exchange mechanism 800 is arranged in the inside of the cylinder body 500, the heat exchange mechanism 800 comprises a capillary pipe 810 for conveying heat exchange medium, the capillary pipe 810 for conveying heat exchange medium, the capillary pipe 810 exchanges heat with the air outside the capillary pipe 810 during conveying heat exchange medium to realize refrigeration or heating, when the air flows from top to bottom and contacts the large area capillary pipe 810, the heat exchange medium in the capillary pipe 810 exchanges heat with the air,

[0049] Specifically, when 7℃ water passes through the inside of the capillary pipe 810, due to the heat conduction between the capillary pipe 810 and the air layer close to the surface of the capillary pipe 810, the natural convection of air is caused, the air flows downward in the cylinder body 500 when it meets cold, and the cold air accumulates at the bottom of the inside of the cylinder body 500, and then the cold air is discharged from the exhaust hole 530 of the outer wall of the cylinder body 500 (refrigeration);

[0050] When hot water passes through the inside of the capillary pipe 810, the hot water flows in the capillary pipe 810, the temperature of the surface of the capillary pipe 810 is increased through the heat conduction of the pipe wall, the high temperature of the surface of the capillary pipe 810 heats the air through heat conduction, and finally the warm air is discharged from the exhaust hole 530 of the outer wall of the cylinder body 500 (heating).

[0051] As shown in Figure 2 , the outer wall of the cylinder body 500 is provided with a wind guide cylinder 510, and the air flow cavity is arranged between the wind guide cylinder 510 and the cylinder body 500, after the cold or warm air is discharged through the exhaust hole 530, the cold air enters the cavity, and more and more cold or warm air accumulates in the cavity;

[0052] As shown in Figure 2As shown, the top of the protection cylinder 200 is inserted with the mounting seat 100, the middle part of the mounting seat 100 is provided with a through hole, and the through hole is fixed with the exhaust fan 120. The exhaust fan 120 is started, and the exhaust fan 120 is a low-speed fan. The exhaust fan 120 moves the air in the cavity upward, and the air is discharged to the inner cavity of the air guide plate 110 through the through hole of the mounting seat 100, as shown in the figure. Figure 2 As shown, the top of the cylinder body 500 is inserted with the main air guide box 300, the top of the main air guide box 300 is connected with the auxiliary air guide box 310, the main air guide box 300 and the auxiliary air guide box 310 are both provided with vertical air holes, and the air holes of the two are communicated. The air passes through the air hole of the main air guide box 300, then passes through the air hole of the auxiliary air guide box 310, and then is discharged to the inner cavity of the air guide plate 110 by the exhaust fan 120, as shown in the figure. Figure 2 As shown, the top of the mounting seat 100 is inserted with the air guide plate 110, and the outer wall of the air guide plate 110 is provided with horizontal and inclined upward direction exhaust holes. Under the action of wind pressure, the air in the inner cavity of the air guide plate 110 is discharged from the exhaust hole of the air guide plate 110. In actual use, the air conditioner refrigeration and heating device of the application is placed at the corner of the room, the height of the exhaust hole of the air guide plate 110 is higher than the height of the user, and the cold air or warm air is continuously discharged. In the room, it flows horizontally or in an inclined direction, and does not blow to the user's body, and finally mixes in the indoor air, so as to achieve the purpose of cooling or heating the indoor air.

[0053] As shown in the figure, Figure 1 As shown, the heat exchange medium circulating device 1000 adopts a circulating pump as a power source, and a water tank as a heat exchange medium transfer storage tank. The water tank can be connected with the water pipe of the external heat pump device, and cold water or hot water is provided by the external heat pump device. The application uses cold water or hot water as the heat exchange medium.

[0054] As shown in the figure, Figure 5 As shown, the heat exchange mechanism 800 adopts a plurality of capillary tubes 810, which are vertically distributed in the inside of the cylinder body 500. A plurality of liquid discharge pipes 820 are also arranged at the top of the liquid collecting pipe 830, and each liquid discharge pipe 820 corresponds to a capillary tube 810. The plurality of capillary tubes 810 share the same hollow pipe 840, as shown in the figure. Figure 6 As shown, a single capillary tube 810 is a disc-shaped structure, and the flow path of the heat exchange medium is from the liquid inlet pipe 910 to the liquid collecting pipe 830, to the liquid discharge pipe 820, to the outer edge extension end of the capillary tube 810, to the center end of the capillary tube 810, to the hollow pipe 840, and finally to the return pipe 920.

[0055] As shown in the figure, Figure 1 , Figure 5As shown, the heat exchange medium is extracted by the circulating pump into the circulating pipeline 900, and then into the liquid collecting pipe 830. After the inside of the liquid collecting pipe 830 is filled with the heat exchange medium, the heat exchange medium is pressed into the drain pipe 820 under the action of pressure. The drain pipe 820 delivers the heat exchange medium to the capillary tube 810. After the heat exchange medium passes through the capillary tube 810, the capillary tube 810 conducts the heat of the air to the heat exchange medium. The heat exchange medium is delivered downward through the hollow pipe 840, and then flows back to the water tank through the return pipe 920. The heat exchange medium is extracted by the external heat pump device for heat conversion again, and then new heat exchange medium is supplied to the water tank again. The heat exchange medium is supplied in a circulating manner and continuously flows in the capillary tube 810, so as to realize continuous heat exchange and achieve the purposes of refrigeration or heating.

[0056] It should be noted in the present application that the heat exchange and cooling are mainly performed by using 7℃ water because, after scientific calculation and considering the heat exchange efficiency, the temperature on the surface of the capillary tube 810 is usually 1-2℃ higher than the water temperature. This temperature is already far lower than the dew point temperature of most indoor ambient air. The 7℃ cold water can ensure that the surface of the capillary tube 810 is sufficiently cold, so that the water vapor in the air entering the cylinder body 500 can be condensed and separated out smoothly, thereby achieving the purpose of cooling.

[0057] In this embodiment, the capillary tube 810 forms a pipe network structure based on a large area, so as to realize efficient heat conversion. When refrigerating, cold water is supplied into the capillary tube 810, and the refrigeration effect is achieved by absorbing the heat of the surrounding air. When heating, hot water is supplied into the capillary tube 810, and the heating purpose is achieved by releasing heat to the surrounding air.

[0058] This structure mainly uses convection heat exchange, and the heat exchange process is free of fan noise and operates quietly, which is especially suitable for indoor environment.

[0059] In addition, an upwardly guiding air discharge structure (the air guiding cylinder 510, the main air guiding box 300, the auxiliary air guiding box 310, the mounting seat 100 and the air guiding plate 110) is arranged outside the heat exchange mechanism 800. The adjusted air is obliquely upwardly or horizontally discharged by the low-speed air blower 120, so as to avoid direct blowing of the air flow to the human body and effectively improve the comfort and use experience.

[0060] After the air conditioner refrigeration and heating device is used for a long time, the following problems exist: the air contains dust, soot, bacteria and other impurities. Although the filter structure filters the impurities, the impurities inevitably enter the cylinder body 500 after long-term use. In the refrigeration process, when the surface temperature of the capillary tube 810 is lower than the dew point temperature of the indoor air, water droplets will condense on the surface of the capillary tube 810, and the impurities will adhere to the surface of the capillary tube 810. Moreover, in the long-term humid environment, the dust in the air provides an ideal breeding environment for mold and bacteria. The mold smell or earthy smell produced by the metabolism of microorganisms enters the indoor environment with the air circulation, causing the indoor environment to be polluted and having a foul smell during refrigeration and heating.

[0061] In order to solve the above problems, the existing solution is to disassemble the internal structure of the air conditioner and clean each structure one by one, but this cleaning method requires a lot of operation time and certain technical requirements, which is difficult for users to achieve. In order to solve this problem, the following embodiments are provided:

[0062] As shown in Figure 4 The inside of the cylinder 500 is provided with a spray pipe 700 at the top end of the hollow pipe 840, and the spray pipe 700 is continuously supplied with cleaning liquid, which can wash the capillary tube 810 below the spray pipe 700.

[0063] Specifically, the bottom of the spray pipe 700 is provided with a plurality of nozzles 720 facing the capillary tube 810, and the spray pipe 700 is connected with a conduit 710, the nozzles 720 are arranged towards the capillary tube 810, the nozzles 720 are atomizing nozzles, and the cleaning liquid sprayed by the nozzles 720 has small pressure and will not cause impact damage to the capillary tube 810, so as to ensure the structure of the capillary tube 810;

[0064] The end of the conduit 710 penetrates the cylinder 500, the air duct 510 and the protective cylinder 200, and extends to the outside of the protective cylinder 200. During the cleaning of the capillary tube 810, the user can use the external cleaning equipment (not shown in the figure). The existing cleaning equipment usually uses a water pump to connect a cleaning liquid tank, the water outlet of the water pump is connected with a hose, and the end of the hose is connected with the conduit 710 by screwing. The cleaning liquid enters the conduit 710 in the form of high pressure under the extraction of the water pump, and is finally sprayed from the nozzles 720 and falls on the capillary tube 810 from top to bottom, so that the surface of the capillary tube 810 is washed clean;

[0065] This embodiment is based on the structure of the capillary tube 810, and a spray cleaning system (conduit 710, spray pipe 700, nozzle 720) is arranged on the upper part of the capillary tube 810. The spray pipe 700 is connected with a cleaning liquid source through an external conduit, the cleaning liquid is input into the spray pipe 700 through the conduit 710, and uniform water mist is formed through the nozzles 720 at the bottom, so that the outer wall of the capillary tube 810 can be regularly washed. This structure does not need to be disassembled for cleaning, significantly reduces the maintenance difficulty, effectively avoids the accumulation of dust and dirt, and ensures the heat exchange efficiency and system stability of the capillary tube 810 during long-term operation.

[0066] As shown in Figure 4 The upper part of the collecting pipe 830 is provided with a partition plate 730, one side of the partition plate 730 is connected with a dirt outlet pipe 740, the partition plate 730 separates the collecting pipe 830 from the capillary tube 810, and at the same time, the inside of the cylinder 500 is divided into two space regions, the upper space region is provided with the spray pipe 700 and the capillary tube 810, and the lower space region is provided with the collecting pipe 830,

[0067] In the process of rinsing, the generated sewage automatically falls on the top of the partition plate 730, and the top of the partition plate 730 is inclined, and the lowest part of the top surface of the partition plate 730 corresponds to the end of the sewage pipe 740 (as shown in Figure 4 The sewage is discharged from the sewage pipe 740 to the outside of the cylinder body 500, the wind guide cylinder 510 and the protective cylinder 200 (in the refrigeration process, the water droplets generated on the outer surface of the capillary tube 810 also fall on the top of the partition plate 730, and finally discharged from the sewage pipe 740 to the outside of the cylinder body 500, the wind guide cylinder 510 and the protective cylinder 200).

[0068] It should be noted that the water droplets generated in the process of rinsing the capillary tube 810 fall freely downward, and in this process, the water droplets fall on the outer wall of the capillary tube 810 and splash around. In the process of splashing, since the air outlet holes 530 on the outer wall of the cylinder body 500 are inclined upward, the water droplets will not splash to the outside of the cylinder body 500 through the air outlet holes 530, which is beneficial to protect other structures outside the cylinder body 500 and avoid the problem of odor generated inside the air conditioner refrigeration and heating device due to sewage residue.

[0069] It should be noted that the guide pipe 710 is a disc structure, and the disc center bottom is fixed by glue with the top of the hollow pipe 840 (as shown in Figure 6 The top end of the hollow pipe 840 is fixed with a cylindrical support block made of plastic material, and the guide pipe 710 is also made of plastic material. The support block is used to support the guide pipe 710 to ensure the stability of the guide pipe 710,

[0070] As shown in Figure 2 The guide pipe 710 penetrates the hole position of the cylinder body 500, the wind guide cylinder 510 and the protective cylinder 200, and is sealed by a sealing rubber ring to improve the sealing performance of the protective cylinder 200 and the wind guide cylinder 510, avoid air from the gap between the guide pipe 710 and the wind guide cylinder 510 and the protective cylinder 200, and ensure the use experience of the air conditioner.

[0071] In order to solve the problem that the just discharged cold or warm air is short-circuited and sucked in, the application provides the following embodiments:

[0072] As shown in Figure 2 , Figure 7 The top of the cylinder body 500 is provided with an air inlet assembly 400, which is used to suck the indoor air around the bottom of the air conditioner refrigeration and heating device into the cylinder body 500.

[0073] Specifically, the air inlet assembly 400 includes an air inlet box 440 connected to the top of the cylinder body 500, the bottom of the air inlet box 440 is provided with a gas guide hole 430 corresponding to the air inlet hole 520, one side of the air inlet box 440 is connected with a gas guide pipe 420, the top end of the gas guide pipe 420 is fixed with an air extractor 410, the bottom end of the gas guide pipe 420 is connected with a base 600, the top of the base 600 is provided with a insertion hole 630 matched with the end of the gas guide pipe 420, the sidewall of the base 600 is provided with a plurality of air inlets 620;

[0074] In the air inlet process of refrigeration or heating, the air extractor 410 is started to extract air, the air enters the base 600 from the air inlet 620, then enters the gas guide pipe 420 through the insertion hole 630, passes through the channel of the air extractor 410 to enter the air inlet box 440, the air in the air inlet box 440 passes through the gas guide hole 430 under the subsequent continuous air pressure, then passes through the air inlet hole 520, and finally enters the cylinder body 500;

[0075] In this embodiment, in order to optimize the air flow organization and improve the energy utilization efficiency, the independent air inlet assembly 400 is arranged at the top of the cylinder body 500, the air inlet end of which extends to the bottom of the equipment and is away from the air exhaust area, which effectively avoids the short-circuiting of the just discharged cold or warm air, reduces the energy circulation loss, ensures that the refrigeration or heating effect is concentrated on the indoor environment, and thus improves the overall energy efficiency and adjustment performance of the system.

[0076] It should be noted in the present application that, as shown in Figure 2 The sidewall of the base 600 is wrapped with a filter plate 610, the filter plate 610 adopts the same filter structure as the existing air conditioner, and the filter plate 610 adopts two semicircular micro-porous filter screens, the ends of which are positioned by magnetic attraction, specifically, the filter plate 610 directly filters the impurities in the air to avoid the dust in the air entering the cylinder body 500 and reduce the pollution of the impurities to the capillary tube 810, so as to keep the surface of the capillary tube 810 free of impurities, the air directly contacts the capillary tube 810, the heat conduction efficiency is not affected, and the heat exchange efficiency of the capillary tube 810 is ensured.

[0077] The above only describes some exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the above drawings and descriptions are illustrative in nature and should not be understood as limiting the scope of protection of the claims of the present application.
