Description

Technical Field

[0001] This invention relates to the field of swimming pool machine technology, specifically to a multifunctional mini swimming pool machine and its control method. Background Technology

[0002] As the core temperature control device for small home swimming pools, the mini pool machine mainly consists of a compressor, finned heat exchanger, water-side heat exchanger, four-way reversing valve, throttling components (such as electronic expansion valve or capillary tube), and circulating water pump. These components work together to achieve the function of regulating the temperature of the pool water.

[0003] The compressor serves as the core power source, driving the refrigerant to circulate within the system. The four-way reversing valve switches the refrigerant flow direction to achieve the conversion between cooling and heating modes. In cooling mode, the finned heat exchanger acts as a condenser to dissipate heat, while the water-side heat exchanger acts as an evaporator to absorb heat from the pool water to achieve cooling. In heating mode, the finned heat exchanger switches to evaporator mode to absorb ambient heat, while the water-side heat exchanger switches to condenser mode to release heat to the pool water to achieve heating.

[0004] Traditional mini pool machines are generally limited to simple cooling and heating, only adjusting the water temperature according to user needs to suit different seasons. However, as home mini pools are places to enhance quality of life and leisure experience, users often need to drink beverages while exercising and relaxing around the pool, and this need varies significantly with the seasons. Since traditional mini pool machines lack beverage temperature control, users need to purchase additional refrigerators, heating boxes, and other equipment to cool and heat drinks separately. This not only increases the cost of appliances but also occupies space around the pool, reducing overall convenience and comfort. Therefore, this invention proposes a multi-functional mini pool machine and its control method to effectively solve the above-mentioned drawbacks. Summary of the Invention

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1: Please refer to Figure 1 - Figure 11 This application proposes a multi-functional mini swimming pool machine, including a pool machine body 100. Inside the pool machine body 100, there are a water-side heat exchanger 200, a finned heat exchanger 300, a four-way reversing valve 400, and a compressor 500 connected in sequence. A vent is provided on one side of the pool machine body 100, directly opposite the finned heat exchanger 300, and a fan is installed in the vent. Specifically, the refrigerant outlet of the compressor 500 is connected to the water-side heat exchanger 200 and the finned heat exchanger 300 respectively through the four-way reversing valve 400. It should be noted that since the pool machine can be used for both cooling and heating, the circulation direction of the refrigerant in the pipeline is opposite during cooling and heating.

[0043] Furthermore, the pool machine body 100 has casters at all four corners of its bottom, ventilation openings on both sides of its side walls, and a control panel on its top.

[0044] like Figure 4As shown, a storage compartment 101 is embedded in one side of the pool machine body 100. A beverage compartment 102 is located inside the storage compartment 101 and near the opening. The openings of the storage compartment 101 and the beverage compartment 102 are aligned. A door 103 is also provided at the opening of the storage compartment 101. A heat exchange plate 104 is fixedly embedded in one side wall of the beverage compartment 102. The inner and outer sides of the heat exchange plate 104 are located on the inner and outer sides of the beverage compartment 102, respectively. Specifically, both the storage compartment 101 and the beverage compartment 102 are made of hard plastic. In addition, the beverage compartment 102 is used to hold beverages that need to be cooled or heated. One end of the door 103 is hinged, and the other end is magnetically attached to the storage compartment 101 to facilitate easy opening of the door 103 by staff.

[0045] Specifically, the water-side heat exchanger 200 adopts a shell-and-tube heat exchanger. The side wall of the water-side heat exchanger 200 has an inlet and an outlet. The bottom of the water-side heat exchanger 200 also has a refrigerant inlet and a refrigerant outlet. Several first heat-conducting parts 202 are fixedly embedded in the side wall of the water-side heat exchanger 200. Specifically, the side wall of the pool machine body 100 is provided with an inlet end 105 and an outlet end 106. The inlet and outlet of the water-side heat exchanger 200 are respectively connected to the inlet end 105 and the outlet end 106 through flexible hoses.

[0046] In practical application, this embodiment only requires connecting the inlet end 105 and the outlet end 106 to the swimming pool with water pipes, and installing a water pump on one water pipe to continuously pump the water in the pool into the water-side heat exchanger 200. After heat exchange, the water returns to the pool through another water pipe, thus forming a cycle.

[0047] Furthermore, the water-side heat exchanger 200 includes an outer shell 201 and several heat-conducting pipes 203. A first partition 204 is located on the inner side of the outer shell 201 near the bottom. A second partition 205 is located below the first partition 204. The two ends of the heat-conducting pipes 203 are respectively located below the second partition 205 and between the first and second partitions 204 and 205, with the remaining portion of the heat-conducting pipes 203 located above the first partition 204. The refrigerant inlet communicates with the area between the first and second partitions 204 and 205; the refrigerant outlet communicates with the area below the second partition 205. The heat-conducting pipes 203 are made of copper, which has good thermal conductivity, and are U-shaped. It should be noted that during the refrigeration cycle, the refrigerant enters the area between the first and second partitions 204 and 205 from the refrigerant inlet; during the heating cycle, the refrigerant enters the area below the second partition 205 from the refrigerant outlet.

[0048] In addition, several baffles 206 are alternately arranged on the left and right sides inside the outer casing 201, and heat-conducting pipes 203 pass through several baffles 206; the function of the baffles 206 is to increase the flow path of water in the heat exchanger, thereby improving heat exchange efficiency. Meanwhile, several heat-conducting plates 207 are integrally formed on the inner surface of the first heat-conducting part 202, such as... Figure 10 As shown, the heat-conducting sheet 207 is used to increase the contact area between water and the heat-conducting material, and further to improve the heat conversion efficiency.

[0049] In this embodiment, a refrigerator heat exchanger 600 is movably disposed between the beverage compartment 102 and the water-side heat exchanger 200. The refrigerator heat exchanger 600 includes an insulation shell 601 and a heat exchange tube 602 located inside the insulation shell 601. The two ends of the heat exchange tube 602 are respectively connected to the refrigerant inlet and the refrigerant outlet of the water-side heat exchanger 200. A plurality of heat-conducting sleeves 603 are tightly fitted on the outside of the heat exchange tube 602. A plurality of second heat-conducting parts 604 are fixedly embedded on the side wall of the insulation shell 601. The plurality of second heat-conducting parts 604 are respectively connected to the plurality of heat-conducting sleeves 603. Specifically, the refrigerator heat exchanger 600 is cylindrical in shape and can move left and right in the area between the water-side heat exchanger 200 and the beverage compartment 102 to get closer to the beverage compartment 102 or the water-side heat exchanger 200.

[0050] It is worth mentioning that the outer wall of the beverage compartment 102 is covered with an insulation layer 107. A heat exchange notch is provided in the insulation layer 107 directly opposite the refrigerator heat exchanger 600, and the outer surface of the heat exchange plate 104 is located inside this notch. The insulation layer 107 is made of sponge material, and the portion of the heat exchange plate 104 located outside the beverage compartment 102 is narrower, while the portion located inside the beverage compartment 102 is thicker. Figure 9 As shown. In addition, the first heat-conducting part 202, the second heat-conducting part 604 and the heat exchange plate 104 are all made of copper, which has good thermal conductivity.

[0051] It should be noted that when the refrigerator heat exchanger 600 is located near the water-side heat exchanger 200, several second heat-conducting parts 604 can abut against several first heat-conducting parts 202; when the refrigerator heat exchanger 600 is located near the beverage compartment 102, several second heat-conducting parts 604 abut against the heat exchange plate 104. That is, when the refrigerator heat exchanger 600 is located near the water-side heat exchanger 200, it can assist the water-side heat exchanger 200 in heat exchange, thereby improving the heat exchange efficiency of the water-side heat exchanger 200; conversely, when the refrigerator heat exchanger 600 is located near the beverage compartment 102, it can cool or heat the beverage compartment 102.

[0052] In this embodiment, two sealing sleeves are provided through the side wall of the outer casing 201. The two sealing sleeves are located below the second partition 205 and between the first partition 204 and the second partition 205, respectively. Both ends of the heat exchange tube 602 extend out of the bottom wall of the insulation casing 601 and pass through the two sealing sleeves. Specifically, the inner ring of the sealing sleeve is provided with a rubber sealing ring to enhance the sealing performance and prevent refrigerant leakage.

[0053] The outer surfaces of the first heat-conducting part 202 and the second heat-conducting part 604 are both serrated. The outer surface of the heat exchange plate 104 is integrally formed with a plurality of bosses 1041, and the outer ends of the bosses 1041 are also serrated. Specifically, when the first heat-conducting part 202 and the second heat-conducting part 604 are in contact, the serrations on their surfaces can mesh with each other. When the refrigerator heat exchanger 600 is located on the side close to the beverage compartment 102, the serrations on the outer surfaces of the plurality of second heat-conducting parts 604 and the serrations on the outer surfaces of the plurality of bosses 1041 can also mesh with each other, thereby increasing the contact area and improving the heat conversion efficiency.

[0054] In some embodiments of this application, the bottom end of the insulation shell 601 is provided with a connecting frame 108, and the bottom of the accommodating compartment 101 is provided with an electric push rod 109. The movable end of the electric push rod 109 is connected to the connecting frame 108, and the electric push rod 109 can push the refrigerator heat exchanger 600 closer to the beverage compartment 102 or closer to the water-side heat exchanger 200. That is, the electric push rod 109 is used to directly control the refrigerator heat exchanger 600 to switch between the two operating conditions.

[0055] Specifically, the insulation shell 601 includes a bottom cover 6011 and an insulation cylinder 6012. The insulation cylinder 6012 and the bottom cover 6011 are rotatably connected by a damping bearing. The heat exchange tube 602 is located in the internal region of the insulation shell 601 and is U-shaped. One section of the heat exchange tube 602 is coaxially arranged with the insulation cylinder 6012. Several heat-conducting sleeves 603 are fitted over this section of the heat exchange tube 602. A driven gear ring 6013 is fixedly fitted on the outside of the insulation cylinder 6012. A mating rack 110 is also provided inside the accommodating compartment 101 and between the beverage compartment 102 and the water-side heat exchanger 200. When the insulation shell 601 passes the mating rack 110, the mating rack 110 can drive the driven gear ring 6013 to rotate 180°. That is, the rack 110 is located on one side of the insulation cylinder 6012, and the rack 110 is fixedly connected to the inner wall of the accommodating chamber 101 through the connecting rod.

[0056] When the insulation cylinder 6012 rotates, the second heat-conducting part 604 and the heat-conducting sleeve 603 will also rotate around the heat exchange tube 602, so that the outer end of the second heat-conducting part 604 rotates from one side to the other side, so that the second heat-conducting part 604 can cooperate with the first heat-conducting part 202 and the heat exchange plate 104 respectively.

[0057] In summary, in practical applications, when the beverage compartment 102 is not needed, the refrigerator heat exchanger 600 is positioned closer to the water-side heat exchanger 200, with the first heat-conducting part 202 and the second heat-conducting part 604 in contact. Refrigerant enters both the water-side heat exchanger 200 and the refrigerator heat exchanger 600 simultaneously. The heat-conducting pipe 203 in the water-side heat exchanger 200 directly exchanges heat with the water, while the heat exchange pipe 602 in the refrigerator heat exchanger 600 exchanges heat with the water through the heat-conducting sleeve 603, the second heat-conducting part 604, the first heat-conducting part 202, and the heat-conducting plate 207. It is worth noting that although the refrigerator heat exchanger 600 requires heat conduction through multiple components to exchange heat with the water, there is inevitably some heat loss. After multiple tests, the thermal efficiency of the refrigerator heat exchanger 600 in this embodiment can be maintained between 50% and 60%, with the specific figure affected by factors such as ambient temperature and medium flow rate.

[0058] When a user needs to use the beverage compartment 102 to cool or heat a beverage, the refrigerator heat exchanger can be positioned closer to the beverage compartment 102, at which point the second heat-conducting part 604 and the heat exchange plate 104 are in contact. Refrigerant can still simultaneously enter both the water-side heat exchanger 200 and the refrigerator heat exchanger 600. The heat-conducting pipe 203 in the water-side heat exchanger 200 directly exchanges heat with the water, while the heat exchange pipe 602 in the refrigerator heat exchanger 600 exchanges heat with the air inside the beverage compartment 102 through the heat-conducting sleeve 603, the second heat-conducting part 604, and the heat exchange plate 104, thereby heating or cooling the beverage.

[0059] Example 2: This application also proposes a control method for a multi-functional mini swimming pool machine, applicable to the multi-functional mini swimming pool machine in Example 1, specifically including the following steps:

[0060] In refrigeration mode, the refrigerant output by compressor 500 enters finned heat exchanger 300 through four-way reversing valve 400, then flows through water-side heat exchanger 200 and refrigerator heat exchanger 600 and returns to compressor 500 through four-way reversing valve 400.

[0061] In heating mode, the refrigerant output by compressor 500 enters water-side heat exchanger 200 and refrigerator heat exchanger 600 through four-way reversing valve 400, then flows through finned heat exchanger 300 and returns to compressor 500 through four-way reversing valve 400.

[0062] When the beverage compartment 102 needs to be used, the refrigerator heat exchanger 600 is positioned on the side close to the beverage compartment 102, and the second heat-conducting part 604 and the heat exchange plate 104 are in contact. At this time, the heat exchange tube 602 in the refrigerator heat exchanger 600 exchanges heat with the air in the beverage compartment 102 through the heat-conducting sleeve 603, the second heat-conducting part 604 and the heat exchange plate 104, thereby heating or cooling the beverage.

[0063] When the beverage compartment 102 is not needed, the refrigerator heat exchanger 600 is positioned on the side closer to the water-side heat exchanger 200, and the second heat-conducting part 604 and the first heat-conducting part 202 are in contact. At this time, the heat exchange tube 602 inside the refrigerator heat exchanger 600 exchanges heat with the water through the heat-conducting sleeve 603, the second heat-conducting part 604, the first heat-conducting part 202, and the heat-conducting plate 207.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
