For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0033] Example 1

[0034] See also Figure 1 and Figure 2 This embodiment provides a portable air conditioner, including a main unit 1, an indoor air conditioning unit 2, and a water inlet connection pipe 3, a water return connection pipe 4, and power supply and control wires for connecting the main unit 1 and the indoor air conditioning unit 2. The power supply and control wires include power supply wires for power supply and control wires for control. The portable air conditioner is used for temporary structures, including but not limited to tents, simple modular assembled houses, etc.

[0035] like Figure 4 and Figure 6As shown, the indoor air conditioning unit 2 includes a second housing 201, which is the housing of the indoor air conditioning unit. A water-air heat exchanger 202, a blower fan 203, an air duct housing 204, a guide housing 205 and an air supply panel 206 are arranged in the second housing 201. The front of the second housing 201 is opened, and the water-air heat exchanger 202, the air duct housing 204, the blower fan 203, the guide housing 205 and the air supply panel 206 are arranged in sequence from the back to the front of the second housing 201. Air inlets are arranged on both sides of the second housing 201, and the air inlets are in a grille shape.

[0036] like Figure 6 and Figure 8-Figure 11 As shown, the back of the air duct housing 204 has a radiator accommodating cavity 2041, the water-air heat exchanger 202 is arranged in the radiator accommodating cavity 2041, the front of the air duct housing 204 is provided with a circular through hole 2042 connected to the radiator accommodating cavity 2041, and the blowing fan 203 is installed on the front of the air duct housing 204 and is located at the circular through hole 2042. The blowing fan 203 uses a centrifugal fan, its air intake is located at the rear side of its housing, and its air outlet is located at the upper side of its housing, and the air intake of the blowing fan 203 is aligned with the circular through hole 2042. The front of the air duct housing 204 is also provided with an air duct enclosure 2043, the air duct enclosure 2043 encloses the air duct, and the air duct is semicircular or U-shaped. The air duct enclosure 2043 includes a flat plate at the bottom and an arc plate located above the flat plate, and one end of the flat plate is provided with an air inlet notch, and the air inlet notch is aligned with the air outlet of the blowing fan 203. When the blowing fan 203 is started, the wind outside the second housing 201 first enters the second housing 201 through the air inlets provided on both sides of the second housing 201, then enters the blowing fan 203 after passing through the water-air heat exchanger 202, and is then discharged by the blowing fan 203 into the air duct surrounded by the air duct enclosure 2043. At this time, when cold water is passed into the water-air heat exchanger 202, the blowing fan 203 will discharge cold air.

[0037] like Figure 6 , Fig.12 and Fig.13As shown, the front of the guide housing 205 is provided with an installation groove 2051 for installing the air supply panel 206, and the bottom wall of the installation groove 2051 is provided with an air guide port, and a rotatable air guide panel 2052 is provided at the air guide port. The air guide panel 2052 is annular, including an outer ring wall, an inner ring wall, and an air guide strip arranged between the outer ring wall and the inner ring wall, one end of the air guide strip is connected to the inner wall of the outer ring wall, and the other end is connected to the outer wall of the inner ring wall. There are multiple air guide strips evenly distributed along the circumferential direction of the outer ring wall and the inner ring wall, and there is an air guide gap between adjacent air guide strips. The guide housing 205 is also provided with multiple clamping grooves 2053 for clamping and installing the air supply panel 206. The air supply panel 206 includes a panel frame 2061 and an air guide plate assembly 2063 arranged on the panel frame 2061. The panel frame 2061 surrounds a cold air supply port. The air guide plate assembly 2063 includes a plurality of air guide plates arranged in sequence in the upper and lower directions. Each air guide plate is rotatably mounted on the panel frame 2061 and partially blocks the cold air supply port. Each air guide plate can be rotated up and down within a certain range to adjust the direction of the air blown out from the cold air supply port. The back of the panel frame 2061 is provided with a snap-on plate structure 2062 having the same number as the snap-on slots 2053 and corresponding positions. The air supply panel 206 is snap-on mounted on the guide housing 205 through the snap-on plate structure 2062. At this time, the snap-on plate structure 2062 is inserted into the snap-on slot 2053.

[0038] When the blowing fan 203 is started, the exhaust air of the blowing fan 203 enters the air duct surrounded by the air duct enclosure 2043 through the air inlet notch set on the flat plate of the air duct enclosure 2043. Since the air inlet notch is set at one end of the flat plate, the exhaust air of the blowing fan 203 flows along the curved plate of the air duct enclosure 2043 and fills the air duct surrounded by the air duct enclosure 2043 more evenly. Due to the restriction of the air duct enclosure 2043, the wind entering the air duct will flow forward and first pass through the air guide panel 2052. The air guide panel 2052 rotates to stir and disperse the air discharged from the air duct, making the exhaust air more uniform. The wind stirred and dispersed by the air guide panel 2052 is finally guided by the air guide plate assembly 2063 of the air supply panel 206 and then blown out. Therefore, under the joint action of the air duct housing 204, the guide housing 205 and the air supply panel 206, the exhaust air of the blowing fan 203 can be discharged evenly, and the blowing wind direction can be adjusted by the user.

[0039] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the host unit 1 includes a first shell 101, which is the shell of the host unit. A compressor 103, an evaporator 104, a condenser 105, an electric control board 106, a water tank 107, a driving water pump 108, a condensing fan 109 and a receiving chamber 110 for placing the indoor air-conditioning unit 2 are arranged in the first shell 101, and an inlet and outlet opening is arranged on one side of the receiving chamber 110. The indoor air-conditioning unit 2 can be detachably placed in the receiving chamber 110 of the first shell 101, and the connection method between the two can be a snap-on connection, a bolt connection, or a combination of a snap-on connection and a bolt connection. Therefore, the portable air conditioner provided by the utility model has two states, one is an overall state in which the indoor air-conditioning unit 2 is arranged in the receiving chamber 110, as Figure 1 As shown, the air supply panel 206 closes the inlet and outlet openings of the accommodating chamber 110, and together with the first shell 101, forms the appearance of the portable air conditioner. Another is that the indoor air conditioning unit 2 is arranged outside the main unit 1, and the indoor air conditioning unit 2 is connected to the main unit 1 through the water inlet connecting pipe 3, the water return connecting pipe 4 and the power supply and control wires. Figure 2 When in the separated state, the indoor air conditioning unit 2 is placed on a temporary structure. Figure 4 As shown, a U-shaped groove is provided on the upper wall surface of the first shell 101 of the indoor air-conditioning unit 2, and a second handle 207 is hinged in the U-shaped groove. The second handle 207 has two states, one is a retracted state completely located in the U-shaped groove, at which time the indoor air-conditioning unit 2 can be placed in the accommodating cavity 110 of the first shell 101. The other is an extended state in which the second handle 207 is erected. The indoor air-conditioning unit 2 must be taken out of the accommodating cavity 110 of the first shell 101 before the second handle 207 can be erected to be in the extended state. The second handle 207 has at least two functions, one is to make the indoor air-conditioning unit 2 easy to carry, and the other is to hang the indoor air-conditioning unit 2 on the hanging structure of a temporary structure through the second handle 207, such as a connecting frame of a tent, such as a hook set on the wall of a simple assembled board house, etc.

[0040] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the compressor 103, evaporator 104, condenser 105, electric control board 106, water tank 107, driving water pump 108 and condensing fan 109 in the first shell 101 form a cooling water system. This cooling water system has a discharge port and a return port. A drainage joint is provided at the discharge port, and a return joint is provided at the return port. Both the drainage joint and the return joint are located in the accommodating chamber 110 of the first shell 101. The drainage joint is connected to the water inlet of the water-air heat exchanger 202 of the indoor air conditioning unit 2 through the water inlet connecting pipe 3, and the return joint is connected to the drainage port of the water-air heat exchanger 202 of the indoor air conditioning unit 2 through the return water connecting pipe 4. The evaporator 104 is essentially a heat exchanger used for heat exchange between water and refrigerant, so the evaporator 104 can also be said to be a refrigerant-water heat exchanger. Under the action of driving the water pump 108, the water in the water tank 107 enters the evaporator 104, and its temperature drops after heat exchange with the liquid refrigerant or liquid coolant in the evaporator 104. After becoming the required cold water, it enters the water-air heat exchanger 202 of the indoor air-conditioning unit 2 through the water inlet connecting pipe 3, and then enters the water-air heat exchanger 202 of the indoor air-conditioning unit 2 through the water inlet connecting pipe 3. After heat exchange and temperature rise of the wind passing through the water-air heat exchanger 202 under the action of the blowing fan 203, it returns to the water tank 107 through the return water connecting pipe 4, thereby realizing the circulation of water and making the exhaust air of the indoor air-conditioning unit 2 cold air at the same time. The liquid refrigerant in the evaporator 104 absorbs heat from the water and evaporates into gas, which is then sucked into the compressor 103. Under the compression of the compressor 103, it forms high-pressure and high-temperature steam and enters the condenser 105. After heat exchange and cooling with the wind introduced by the condensing fan 109, it becomes high-pressure liquid refrigerant. After passing through the thermal expansion valve, it becomes low-temperature and low-pressure liquid refrigerant and enters the evaporator 104, thus realizing the circulation of the refrigerant.

[0041] like Figure 3 and Figure 5 As shown, the condenser 105 is arranged near a side wall of the first shell 101, and a condensation air inlet is arranged at a position of the side wall of the first shell 101 corresponding to the condenser 105. A condensation air outlet is arranged on the back or rear of the first shell 101, and a condensation fan 109 is arranged at the condensation air outlet. Under the action of the condensation fan 109, the outside air enters the first shell 101 through the condensation air inlet, and is discharged through the condensation air outlet after heat exchange with the refrigerant in the condenser 105.

[0042] like Fig.14As shown, the water-air heat exchanger 202 includes a first header 2021 and a second header 2022, both of which are arranged vertically. The first header 2021 and the second header 2022 are connected by a plurality of parallel flat tubes 2023, each of which is arranged equidistantly from top to bottom, and heat exchange fins 2024 are arranged between adjacent flat tubes 2023, and the heat exchange fins 2024 connect the lower wall surface of the upper flat tube 2023 and the upper wall surface of the lower flat tube 2023. A partition 2025 is arranged in the middle of the first header 2021, and the partition 2025 divides the interior of the first header 2021 into a first chamber and a second chamber, the first chamber is located above the partition 2025, and the second chamber is located below the partition 2025. The flat tube 2023 connected to the first cavity is the upper flat tube 2023, and the flat tube 2023 connected to the second cavity is the lower flat tube 2023. A drain port is provided on the upper end tube wall of the first cavity, and the drain port is the drain port of the water-air heat exchanger 202. A water inlet is provided on the lower end tube wall of the second cavity, and the water inlet is the water inlet of the water-air heat exchanger 202. The cold water generated by the host unit 1 enters the second cavity of the first header 2021 of the water-air heat exchanger 202 through the water inlet connecting pipe 3, and enters the second header 2022 through the lower flat tube 2023 connected to the second cavity. At the same time, under the action of the blowing fan 203, the wind outside the indoor air conditioning unit 2 enters the second shell 201 through the grille-shaped air inlet on both sides of the second shell 201, and after heat exchange and cooling with the heat exchange fins 2024 between the lower flat tube 2023, it becomes cold air and enters the blowing fan 203, and then passes through the air duct, the guide shell 205 and the air supply panel 206 and blows out to cool the interior of the temporary structure where the indoor air conditioning unit 2 is located. The water entering the second header 2022 enters the first cavity of the first header 2021 through the upper flat tube 2023, and finally returns to the water tank 107 through the drain port and the return water connecting pipe set on the upper end of the first cavity.

Due to the effect of the fourth housing 112, the grille-shaped air inlet of the first housing 101 and the grille-shaped air inlet of the second housing 201 are connected and do not block each other, so that when the portable air conditioner is in an integrated state, the indoor air conditioning unit 2 is ventilated normally.

[0044] In some exemplary embodiments, the lower end of the indoor air-conditioning unit 2 is connected to the bottom wall of the accommodating chamber 110 via a slide groove-guide rail structure. This slide groove-guide rail structure can be a slide groove structure set on the bottom wall of the second shell 201 and a guide rail structure set on the bottom wall of the accommodating chamber 110, or it can be a guide rail structure set on the bottom wall of the second shell 201 and a slide groove structure set on the bottom wall of the accommodating chamber 110.

[0045] like Figure 1 and Figure 3As shown, the host unit 1 also includes a third housing 102, in which a plurality of storage batteries 111 are arranged. The storage batteries 111 can be blade batteries, cylindrical lithium batteries, etc. The storage batteries in the third housing 102 are used to power the electrical components of the host unit 1 and the indoor air conditioning unit 2. The first housing 101 is arranged on the third housing 102, and there are various ways of connecting the first housing 101 and the third housing 102, such as bolt connection, clamping, a combination of clamping and bolt connection, etc. The third housing 102 has an electrical interface, which is connected to the power supply interface of the host unit 1 through an electrical connection line, and the electric control board 106 is electrically connected to the power supply interface. The electric control board 106 is a PCB board, on which a frequency conversion module is arranged. A first handle is arranged at the upper end of the first housing 101, and the host unit 1 can be conveniently carried by the first handle. The first handle can have various structural forms, such as an X-shaped handle arranged in the middle of the upper wall of the first housing 101, such as a U-shaped handle arranged at both ends of the upper wall of the first housing 101, etc.

[0046] In addition to providing power, the battery 111 is also a vibration-damping counterweight, and its weight is much greater than the weight of the driving water pump 108 and the compressor 103. The driving water pump 108 and the compressor 103 of the host unit 1 are vibrating components. The noise generated by the compressor 103 when working will be transmitted through the air to the temporary structure where the indoor air-conditioning unit 2 is located. The vibration generated by the driving water pump 108 when working will be transmitted to the indoor air-conditioning unit 2 through the cold water and water inlet connecting pipe 3, thereby generating noise. When the indoor air-conditioning unit 2 is located in a temporary structure, the noise generated by the working vibration of the driving water pump 108 will be transmitted to the temporary structure, causing noise impact to people in the temporary structure.

[0047] In order to reduce the influence of the noise generated when the driving water pump 108 and the compressor 103 are working. The portable air conditioner has the following structure: First, it has a detachable main unit 1 and an indoor air conditioning unit 2. When in use, the main unit 1 is placed outside a temporary structure such as a tent, and the indoor air conditioning unit 2 is placed in a temporary structure such as a tent. Second, the driving water pump 108 is axially arranged horizontally, and the position where the driving water pump 108 is installed on the first shell 101 is provided with a mounting position matching the shape of the lower end of the driving water pump 108, and a vibration reduction structure such as a rubber plate is arranged in the mounting position, and the driving water pump 108 is fixed by an arc-shaped pressing sheet matching the arc-shaped structure of the upper end of the driving water pump 108, and fixed columns are arranged on both sides of the mounting position, and the arc-shaped pressing sheet is fixed to the fixed columns on both sides of the driving water pump 108 by fasteners such as bolts. Third, the water inlet connecting pipe 3 and the return water connecting pipe 4 are both hoses, which can effectively reduce the transmission of vibration. Fourth, a vibration reduction structure such as a rubber plate is arranged at the lower end of the compressor 103. Fifth, there is a vibration reduction structure of a rubber pad + gap between the first shell 101 and the third shell 102. Sixth, a sound-absorbing and noise-reducing structure such as sound-absorbing cotton is arranged on the inner wall of the first shell 101. Seventh, the center of gravity of the driving water pump 108 and the compressor 103 is located at the center of the third shell 102.

[0048] In addition to the battery 111, the water tank 107 and the water therein are also a vibration-damping counterweight. The water tank 107 is arranged close to the driving water pump 108, that is, close to the center position of the third shell 102, and the weight of the counterweight is much greater than the weight of the vibrating component.

[0049] Method of using the portable air conditioner: When setting up a temporary structure such as a tent, start the driving water pump 108, the compressor 103 and the condensing fan 109, and do not start the blowing fan 203. At this time, the portable air conditioner is in a cooling state, which is used to reduce the water temperature in the water tank 107. The water tank 107 is provided with a temperature sensor for detecting the water temperature in the water tank 107, and the temperature sensor is electrically connected to the electric control board 106. A wireless transceiver module is provided on the electric control board 106 and / or in the second housing 201, which is used to wirelessly connect to the remote control. The cooling temperature threshold can be set by the remote control. When the temperature sensor detects that the temperature of the water tank 107 reaches the cooling temperature threshold, the cooling state is stopped, the driving water pump 108 and the compressor 103 are stopped, and the cooling standby state is entered. The portable air conditioner has a normal working state. In the cold delivery standby state, the driving water pump 108 and the blowing fan 203 are first turned on, and the compressor 103 and the condensing fan 109 are turned on after an interval of 0.2-2 seconds. In this way, it enters the normal working state. At this time, the blowing fan 203 blows out cold air to cool down the internal space of the temporary structure where the indoor air conditioning unit 2 is located, and the refrigerant and water are circulated. The standby temperature threshold is set to 9 degrees Celsius. At this time, the outlet water temperature of the main unit 1 is about 4 degrees Celsius. Since this is the initial state of the normal working state of the portable air conditioner, the cold load is high, and the return water temperature will gradually increase. After running for a period of time, the return water temperature is stabilized at about 12 degrees Celsius. At this time, the outlet water temperature of the main unit 1 is about 7 degrees Celsius. The portable air conditioner also has a silent working state, which is used when people sleep in temporary structures. The frequency of the compressor 103 is reduced, the temperature of the water in the water tank 107 is controlled within the range of 9-17 degrees Celsius, and the blowing fan 203 is operated at the lowest power gear or the second lowest power gear. When the temperature of the water in the water tank 107 is below 10 degrees Celsius, the compressor 103 and the condensing fan 109 are not turned on, and the driving water pump 108 and the blowing fan 203 are turned on.

[0050] In some exemplary embodiments, in order to maintain cooling for a longer period of time, the portable air conditioner also has the following structures: First, the water inlet connecting pipe 3 and the water return connecting pipe 4 are wrapped with an insulation layer or an insulation pipe, the insulation pipe is soft and bendable, and the insulation pipe is fixed to the outside of the water inlet connecting pipe 3 and the water return connecting pipe 4 by an adhesive layer or a compression piece. Second, the water tank 107 is a heat-insulating water tank structure, the water tank 107 is wrapped with an insulation layer, and the water tank 107 is made of a material with poor thermal conductivity. Third, an ice cube placement groove is provided on the side wall of the first housing 101, and a pull-out double-layer vacuum insulation structure ice cube placement box is provided in the ice cube placement groove. When going out, ice cubes are placed in the ice cube placement box. When the portable air conditioner is used, the ice cube placement box can be taken out first, and the ice cubes in the ice cube placement box can be added to the water tank 107 to reduce the water temperature in the water tank 107. In this way, the cold delivery standby state can be directly skipped, and in the initial state of high cold load when the portable air conditioner is in normal working state, the compressor 103 does not need to be started, so that the power of the battery 111 can be used for a longer time. Fourth, a plug-in installation structure such as a plug-in tube is provided on the side wall of the first housing 101, and a sunshade device can be plugged and installed in the plug-in installation structure.

[0051] In some exemplary embodiments, a light sensor is further provided on the first shell 101, and the light sensor is electrically connected to the electrical control board 106 of the refrigerant circulation system and the driving water pump 108. The light sensor is used to detect the light intensity in the external environment. A weak light threshold and a strong light threshold are provided in the electrical control board 106. When the light sensor detects that the light intensity in the external environment changes from the weak light threshold to the strong light threshold, the electrical control board 106 automatically increases the detected temperature of the water in the water tank 107, thereby increasing the temperature of the wind blown out by the indoor air-conditioning unit 2, so that the user wakes up naturally.

[0052] In some exemplary embodiments, a water receiving pan and a condensate pump are further provided in the second housing 201. The water receiving pan is located at the lower end of the water-air heat exchanger 202. The water receiving pan is used to receive and store the condensate generated when the air flows through the water-air heat exchanger 202. The condensate pump is provided in the concave part of the water receiving pan. The condensate pump is connected to a condensate drain pipe, which is connected to the first chamber, the second chamber of the water-air heat exchanger 202 or to the return water connection pipe 4 through a tee. The lower surface of the water receiving pan is provided with a heat preservation layer, and the water receiving pan is provided with an overflow hole, which is detachably connected to an overflow pipe.

[0053] The advantages of the portable air conditioner involved in this case are: the refrigerant delivered to the indoor air conditioning unit 2 is cold water, and the cold water is delivered to the indoor air conditioning unit 2 through a hose, and the hose reduces noise. Compared with the refrigerant being directly a refrigerant, first, it is safer. The indoor air conditioning unit 2 is placed in a temporary structure for use. If leakage occurs, the refrigerant leaks into the temporary structure, which will seriously endanger people's health, while the consequences of cold water leakage are lighter. Second, the refrigerant is not suitable for being transported by a hose with vibration reduction and noise reduction effects, and it is easy to leak. Third, if a hard pipe such as a copper pipe is used to transport the refrigerant, it is inconvenient to connect the main unit 1 and the indoor air conditioning unit 2, which makes the portable air conditioner inconvenient to use. Fourth, the refrigerant is used for cooling. The refrigerant entering the water-air heat exchanger 202 exists in three states: gas, gas-liquid coexistence state, and liquid. The heat exchange effect of the refrigerant is poor when it is in the gas state and the gas-liquid coexistence state. Therefore, using cold water for cooling can effectively improve the heat exchange efficiency and effectively extend the service life of the battery 111. At the same time, the volume of the water-air heat exchanger 202 can be reduced, effectively reducing the size of the indoor air-conditioning unit 2, making the indoor air-conditioning unit 2 more portable.
