Description

Technical Field

[0001] This invention relates to the field of refrigeration technology, specifically to an integrated air conditioner. Background Technology

[0002] Currently, a portable air-cooled unit for environmental protection is disclosed, comprising a water tank, a water pump located inside the water tank, a casing located on top of the water tank, a fan located inside the casing, a water curtain located behind the fan, and an air oscillator located in front of the fan. The rear of the fan sequentially includes a motor, a water distribution layer, a water curtain, a water curtain cover, and a dustproof net. The motor is fixed to the water distribution layer via a motor bracket, and the water curtain is fixed to the water curtain cover. A water sprayer is located above the fan and connected to the water pump via a water pipe. The front of the fan sequentially includes a front safety net, an air oscillator, and a fixed air oscillator frame. An air oscillator is mounted on the air oscillator and fixed to the front safety net via an air oscillator fixing frame. A rolling device is located at the bottom of the water tank. This type of portable air-cooled unit relies solely on air cooling, resulting in poor cooling performance. Furthermore, the water supplied to the water curtain from the water tank is not cooled; if the water temperature in the tank is high, it cannot effectively blow out cool air. This results in a very limited cooling effect for the entire machine.

[0003] A portable air conditioner is also disclosed, comprising an air conditioner housing with casters installed at the four corners of its bottom. A display screen and control panel are mounted on the outside of the housing. The housing is divided into an upper layer, a middle layer, and a bottom layer. A motor is installed in the upper layer, connected to a vane and an evaporator. An air outlet is located on the front of the upper layer. A condenser is installed in the middle layer, and an exhaust vent and an air inlet are located on the back of the middle layer. A combined air duct is provided between the evaporator and the condenser. A compressor and a water tank are installed in the bottom layer. During operation, cold air is generated in the upper layer, and warm air is generated in the middle layer. Water produced by the evaporator flows into a water tank and can be sprayed onto the condenser by a water pump within the tank, absorbing the heat generated by the condenser. Some of the water evaporates into the air, increasing humidity and improving the condenser's efficiency. This results in more complete vaporization of the refrigerant in the evaporator, absorbing more heat from the upper layer. In this type of portable air conditioner, the water in the water tank is only output to the condenser to cool it. The air outlet on the upper layer is cooled by the evaporator, which directly cools the air. In other words, it adopts an air-cooled structure. In order to achieve a better cooling effect, this structure requires a large compressor, which increases the cost of the whole unit. In addition, the three-layer layout is not compact enough and increases the overall height.

[0004] A portable air conditioner with a water circulation system is also disclosed, including a compressor, condenser, heat exhaust fan, and water collection tray located inside the air conditioner casing; the water collection tray is located below the condenser; it also includes a water circulation system located inside the air conditioner casing; the water circulation system includes a water pump, a drain pipe, a water-cooled jacket, and a cooling pipe; the water pump is installed inside the water collection tray; the inlet end of the drain pipe is connected to the water pump, and the outlet end is connected to the water-cooled jacket; the compressor exhaust pipe of the compressor extends into the water-cooled jacket; one end of the cooling pipe is connected to the water-cooled jacket, and its surface is provided with multiple spray holes. The water circulation mechanism inserts the compressor exhaust pipe into the water-cooled jacket, and at the same time introduces cold water from the water collection tray into the water-cooled jacket. The cold water exchanges heat with the high-temperature refrigerant in the compressor exhaust pipe, and the hot water after heat exchange enters the cooling pipe. The water flows down through multiple spray holes on the cooling pipe, and by utilizing the principle of heat absorption by evaporation of water, the hot water is rapidly cooled. The cooled water then enters the water collection tray, thus forming a water recycling system. In this way, the high-pressure, high-temperature steam compressed by the compressor is not directly discharged into the condenser. Instead, it undergoes heat exchange with cold water, cooling the high-temperature steam generated by the compressor. Even during prolonged operation, the condenser's temperature remains relatively low, requiring further cooling with cold water spray. This ensures that its heat dissipation and condensation efficiency is consistently maintained at a high level. This type of portable air conditioner utilizes circulating water to cool the high-temperature refrigerant in the compressor's exhaust pipe. The air coming out of the portable air conditioner is still cooled air, and the water circulation does not cool the air outlet. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an integrated air conditioner with a structure of upper heat dissipation, middle cooling and lower water tank, which has good heat dissipation and cooling effect. The evaporator of the compressor is used to cool the water delivered to the second water curtain at the cold air outlet, which can quickly reduce the temperature of the air blown out through the second water curtain. At the same time, the water self-circulation is realized, which can reduce energy consumption.

[0006] The technical solution of the present invention is to provide an integrated air conditioner with the following structure: an outer shell, wherein the outer shell has a first working chamber at the top, a second working chamber in the middle, and a third working chamber at the bottom; a first water curtain assembly is provided in the first working chamber, and a second water curtain assembly is provided in the second working chamber; the third working chamber has a hot water tank, a cooling water tank, and a compressor; the condenser and evaporator of the air conditioning system are respectively placed in the hot water tank and the cooling water tank; a heat exchange cylinder is provided in the cooling water tank, and the heat exchange cylinder is connected to the compressor; water from the cooling water tank enters the second water curtain assembly in the second working chamber through the heat exchange cylinder via a first water pump, and then flows back into the cooling water tank; water from the hot water tank enters the first water curtain assembly via a second water pump and then flows back into the hot water tank; in the third working chamber, the hot water tank cavity, the cooling water tank cavity, and the compressor cavity are integrally formed from insulation material, and the hot water tank cavity, the cooling water tank cavity, and the compressor cavity are independent of each other.

[0007] As an improvement, the heat exchange cylinder is equipped with a first heat exchange coil. The inlet of the first heat exchange coil is connected to the compressor, and the outlet is connected to the inlet of a second heat exchange coil located in the cooling water tank. The water inlet of the heat exchange cylinder is connected to the water outlet of a first water pump located in the cooling water tank, and the water outlet of the heat exchange cylinder is connected to a cold water spray pipe located in the cooling water tank. This arrangement makes the condenser heat exchange effect better and the cooling faster.

[0008] As an improvement, a first water curtain is provided on each of the four sides of the first working chamber, and a first fan is provided inside the first working chamber. The air outlet of the first fan is located at the top of the first working chamber. The water from the hot water tank is transported to the top of the first working chamber and then flows through the first working chamber along the first water curtain, and finally flows back to the hot water tank. The top air outlet and the second water curtains on the four sides are used for heat dissipation, resulting in a large heat dissipation area, good heat dissipation effect and high efficiency.

[0009] As an improvement, a second fan is provided inside the second working chamber. The air outlet of the second fan is located on the front of the second working chamber and is provided with an air outlet grille. Second water curtains are provided on the other sides of the second working chamber. The water from the cooling water tank is transported to the top of the second working chamber and then flows through the second working chamber along the second water curtains, and finally flows back into the cooling water tank. The air is discharged from the front, and the second water curtains on the other three sides are cooled by the cooled water, so that the air discharged from the fan is effectively cooled and the cooling effect is good.

[0010] As an improvement, both the hot water tank and the cooling water tank are equipped with a corresponding water level display. The water level display is a transparent tubular shell with an opening at the top and a connection at the bottom to the corresponding water tank, making it convenient for users to check the water level in the tank at any time.

[0011] As an improvement, the second fan has an impeller in the middle with four blades. A protrusion facing the opposite direction of airflow is provided at the free end of each blade, blocking the airflow behind the blades and thus not affecting the airflow in front of them. This also makes it easier to create a negative pressure zone behind the blades, resulting in better suction and ensuring stable airflow. The protrusion also strengthens the free end of the blades, preventing vibration and noise, thus improving noise reduction. The height of the middle part of the protrusion is greater than the sides, and the transition from the middle to the sides is curved, which facilitates the protrusion's engagement when the blades rotate, reducing wind resistance and lowering energy consumption. The first working chamber is provided with a first partition at the top, a second partition is provided between the first working chamber and the second working chamber, and a third partition is provided between the second working chamber and the third working chamber.

[0012] As an improvement, the top of the first partition is provided with a first annular water storage tank and a second annular water storage tank. The water from the cooling water tank is transported to the first annular water storage tank and then to the second annular water storage tank. The bottom of the second annular water storage tank is provided with several holes, so that the water in the second annular water storage tank can pass through the holes and enter the top of the first water curtain. The first annular water storage tank plays the role of storing water. The water enters the first annular water storage tank and then enters the second annular water storage tank evenly from the first annular water storage tank, so that the water in the second annular water storage tank can flow evenly to the first water curtain on the four sides.

[0013] The second partition has recesses around its top surface, which are interconnected and each recess has a return water inlet that allows water from the second water curtain to flow back into the lower cooling water tank. The recesses also contain protrusions to support the first water curtain and water channels. The protrusions are symmetrically or staggered on both sides of the water channels. The bottom plane of the second partition has grooves to accommodate the spray pipes of the lower water curtain. This design makes it easier for water from the water curtain to collect in the water channels. The platform formed by the recesses is higher than the protrusions to reduce water from entering the platform and instead encourage it to enter the recesses, minimizing water retention on the second partition and preventing mold and odor, thus improving performance. The grooves on the bottom plane of the second partition also reduce the overall height and volume.

[0014] With the above structure, the present invention has the following advantages: 1. Water in the cooling water tank is cooled by the second water pump through the heat exchange cylinder and enters the top of the second cavity. Then, the water exchanges heat with the second water curtain next to the first fan and enters the water tank from top to bottom. The heat exchange cylinder quickly cools the water, so that the temperature of the water entering the second water curtain is low. When the water flows along the first water curtain next to the first fan, it exchanges heat with the water on the first water curtain, so that the air blown out by the second fan is effectively cooled and the temperature of the air coming out is low.

[0015] 2. The combination of water curtain and compressor system results in faster heating and cooling speeds, and due to the properties of water, energy consumption can be reduced by about 20%, while the indoor environment will not be too dry.

[0016] 3. The first working chamber uses top air outlet and four side water curtains for heat dissipation, resulting in a large heat dissipation area, good heat dissipation effect, and high efficiency.

[0017] 4. It achieves self-circulation of water, which can reduce energy consumption; and the water tanks are separated by insulation material, which has a good insulation effect. After the compressor placement chamber is set, the compressor has a better shock absorption effect and less noise during operation; and it is integrally molded, which makes the manufacturing process simpler and the manufacturing cost lower.

[0029] The invention will now be further described with reference to the accompanying drawings.

[0030] like Figure 1-4 As shown, an integrated air conditioner of the present invention includes an outer shell 1. The outer shell 1 contains a first working chamber at the top, a second working chamber in the middle, and a third working chamber at the bottom. The first working chamber contains a first water curtain assembly, and the second working chamber contains a second water curtain assembly. The third working chamber contains a hot water tank 2, a cooling water tank 3, and a compressor 4. The condenser and evaporator of the air conditioning system are respectively housed in the hot water tank 2 and the cooling water tank 3. In the third working chamber, the hot water tank chamber, the cooling water tank chamber, and the compressor chamber are integrally formed from insulation material, and are independent of each other. The hot water tank 2 is located in the hot water tank chamber, the cooling water tank 3 is located in the cooling water tank chamber, and the compressor 4 is located in the compressor chamber. The compressor chamber is situated between the hot water tank chamber and the cooling water tank chamber, resulting in a relatively short and reasonable piping arrangement and relatively low material costs.

[0031] like Figure 2 , Figure 4 , Figure 9 and Figure 10As shown, the cooling water tank 3 is equipped with a heat exchange cylinder 5, which is connected to the compressor 4. Water from the cooling water tank 3 passes through the heat exchange cylinder 5 via the first water pump 8 and enters the second water curtain assembly in the second working chamber, then flows back into the cooling water tank 3. Water from the hot water tank 2 enters the first water curtain assembly via the second water pump 10 and flows back into the hot water tank 2. The heat exchange cylinder 5 is equipped with a first heat exchange coil 6. The inlet of the first heat exchange coil 6 is connected to the compressor, and the outlet is connected to the inlet of the second heat exchange coil 7 located in the cooling water tank 3. The water inlet of the heat exchange cylinder 5 is connected to the outlet of the first water pump 8 located in the cooling water tank 3, and the water outlet of the heat exchange cylinder 5 is connected to the cold water spray pipe 9 located in the cooling water tank 3. This arrangement improves the heat exchange effect of the condenser and makes cooling faster.

[0032] like Figure 1 As shown, the first working chamber is equipped with a first water curtain 14 on each of its four sides, and a first fan 15 is installed inside the first working chamber. In this embodiment, two first fans 15 are provided. The air outlet of the first fan 15 is located at the top of the first working chamber. The water from the hot water tank 2 is transported to the top of the first working chamber and then flows along the first water curtain 14 through the first working chamber, finally flowing back to the hot water tank 2. The first fans 15 carry away the heat of the water flowing over the first water curtain 14.

[0033] like Figure 1 As shown, a second fan 11 is provided in the second working chamber. The air outlet of the second fan 11 is located on the front of the second working chamber and is provided with an air outlet grille 12. The other sides of the second working chamber are provided with a second water curtain 13. The water from the cooling water tank 3 is transported to the top of the second working chamber and then flows through the second working chamber along the second water curtain 13, and finally flows back into the cooling water tank 3.

[0034] Both the hot water tank 2 and the cooling water tank 3 are equipped with a corresponding water level display 16. The water level display 16 is a transparent tubular shell with an opening at the top and a connection at the bottom to the corresponding water tank, making it convenient for users to check the water level in the tank at any time.

[0035] like Figure 3 , Figure 4 and Figure 5 As shown, the second fan 11 has an impeller in the middle, and the impeller has four blades 17. A protrusion 18 is provided at the free end of the blade 17, which is opposite to the air outlet direction. This blocks the airflow behind the blade 17, so as not to affect the airflow in front of the blade 17. It is also easier to form a negative pressure zone behind the blade 17, resulting in better air intake and thus ensuring the stability of the air outlet. The protrusion 18 also strengthens the free end of the blade 17, preventing the free end from vibrating and generating noise, resulting in a better noise reduction effect.

[0036] The height of the middle part of the protrusion 18 is greater than that of the two sides, and the transition from the middle to the two sides is arc-shaped. This makes it easier for the protrusion to cut in when the blade 17 rotates, resulting in less wind resistance and reduced energy consumption. like Figure 5 As shown, there is at least one reinforcing rib near the impeller of blade 17. The reinforcing rib extends along the length of blade 17 and terminates at the middle of blade 17. This reduces vibration when blade 17 rotates, resulting in better noise reduction and more stable pushing effect of blade 17, ensuring air output efficiency. The reinforcing rib is located on the front of blade 17 and has a height of 1-3 mm. This height does not affect the airflow on the surface of blade 17 and strengthens blade 17. It cannot be located on the back, as it would conflict with the airflow caused by protrusion 18 and cause turbulence.

[0037] like Figure 4 As shown, the top of the first working chamber is provided with a first partition 19, the second partition 20 is provided between the first working chamber and the second working chamber, and the third partition 21 is provided between the second working chamber and the third working chamber.

[0038] like Figure 6 As shown, the top of the first partition 19 is provided with a first annular water storage tank 22 and a second annular water storage tank 23. The water from the cooling water tank 3 is transported to the first annular water storage tank 22 and then to the second annular water storage tank 23. The bottom of the second annular water storage tank 23 is provided with several holes, so that the water in the second annular water storage tank 23 passes through the holes and enters the top of the first water curtain 14.

[0039] like Figure 7 and Figure 8 As shown, the top surface of the second partition 20 is provided with recesses 24 around its perimeter. The recesses 24 are interconnected, and each recess 24 has a return water inlet, which allows the water on the second water curtain 13 to flow back into the lower cooling water tank 3. The recesses 24 are provided with protrusions 25 for supporting the first water curtain 14. There are also water channels in the recesses 24. The protrusions 25 are symmetrically or staggered on both sides of the water channels, which makes it easier for the water on the water curtain to collect in the water channels. The height of the platform formed by the recesses 24 is higher than the height of the protrusions 25. This is to reduce the amount of water on the water curtain entering the platform, and instead make it easier for the water to enter the recesses 24, reducing the amount of water staying on the partition and causing mold and odor, thus improving the performance.

[0040] The bottom plane of the second partition 20 is provided with a groove 26 for accommodating the water curtain spray pipe of the lower layer, which can reduce the overall height and reduce the volume.
