Window air conditioners are integrated air conditioners, which include a compressor, a condenser, an evaporator, and a fan. During refrigeration operation, the refrigerant is compressed by the compressor from a low-pressure state to a high-temperature and high-pressure state, and then enters the condenser to release heat and condense into liquid refrigerant. The liquid refrigerant enters the evaporator to evaporate and absorb heat to achieve the cooling effect.

Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0066] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0067] The following provides a detailed description of the embodiments of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0068] Embodiment 1:

[0069] like Figure 1-Figure 3 As shown, the embodiment of the present application provides a cold air conditioner with energy-saving regulation, including a chassis housing 100, a compressor 110, a condenser 120, an evaporator 130, a fan motor 140, a centrifugal fan 150, an axial flow fan 160, and also includes:

[0070] A first air inlet 170 is disposed on the chassis housing 100 and corresponds to the position of the evaporator 130;

[0071] The second air inlet 180 is disposed on one side of the centrifugal fan 150 and opposite to the evaporator 130;

[0072] The water collecting tank 190 is disposed at the bottom of the chassis housing 100 and corresponds to the evaporator 130;

[0073] A first pre-cooling mechanism 200 is disposed at the second air inlet 180;

[0074] The water spray mechanism 300 is installed between the condenser 120 and the axial flow fan 160;

[0075] Among them, the first pre-cooling mechanism 200 includes a first heat exchange tube 210 and a first heat exchange guide plate 220. The first heat exchange tube 210 is provided with a first water pipe 230. The water spraying mechanism 300 is provided with a second water pipe 310. The first water pipe 230 and the second water pipe 310 are both connected to the water collecting tank 190. The water spraying mechanism 300 controls the condensed water in the water collecting tank 190 to flow in the first water pipe 230 and the second water pipe 310.

[0076] The air conditioner circulates the refrigerant in the compressor 110, the condenser 120, and the evaporator 130. The first air inlet 170 corresponds to the position of the evaporator 130. The indoor air is passed through the evaporator 130 by the axial flow fan 160 to achieve indoor cooling. When the air conditioner works for a period of time, fresh air needs to be added to the room to ensure the comfort of the air conditioner. By opening the second air inlet 180, the fresh air is delivered to the room through the centrifugal fan 150, and the delivered fresh air is subjected to a cooling process by the first pre-cooling mechanism 200, so that the impact on the air conditioner power is reduced after the fresh air is added to the room. The evaporator 1 When the first pre-cooling mechanism 200 is working, the condensed water will condense on the surface and drip into the water collecting tank 190 under the action of gravity. The water spraying mechanism 300 is used to transport the condensed water and spray it on the condenser 120. The water in the water collecting tank 190 is extracted by the water spraying mechanism 300. When the first pre-cooling mechanism 200 is working, the condensed water can pass through the first heat exchange tube 210, and the first heat exchange guide 220 can exchange heat with the fresh air for pre-cooling. The first water conduit 230 and the second water conduit 310 can guide the condensed water from the water collecting tank 190 to the first heat exchange tube 210 and the water spraying mechanism 300, thereby achieving the energy-saving effect of the air-conditioning equipment.

[0077] Embodiment 2:

[0078] like Figure 2-Figure 5 As shown, the embodiment of the present application provides a cold air conditioner with energy-saving regulation. In addition to the above technical features, the water spray mechanism 300 further includes:

[0079] The water spray pipe 320 has a middle pipe hole smaller than the pipe holes at both ends;

[0080] The water outlet 321 is located in the middle of the water spray pipe 320;

[0081] A connecting pipe 330 connected to the water spray pipe 320 and corresponding to the axis of the water outlet hole 321;

[0082] The connecting pipe 330 is connected to the second water conduit 310 , the chassis shell 100 is provided with a cover shell 400 adapted to the axial flow fan 160 , and a plurality of water spray pipes 320 are provided and evenly distributed around the axis of the axial flow fan 160 .

[0083] The water spray pipe 320 adopts a middle pipe hole that is smaller than the pipe holes at both ends, and a water outlet hole 321 is set in the middle position of the water spray pipe 320 to form a Venturi structure. When the axial flow fan 160 is working, the high-speed flowing air passes through the water spray pipe 320, and the water in the water collecting tank 190 is extracted by pressure, and then sprayed out through the water spray pipe 320, so that the condensed water splashes on the condenser 120. The connecting pipe 330 is integrally connected with the water spray pipe 320 to maintain a high structural strength. The axis of the connecting pipe 330 is the same as that of the water outlet hole 321, and the connecting pipe 330 is connected to the second water guide pipe 310 to ensure the transportation of condensed water. There are several water spray pipes 320 and they are evenly installed and distributed on the cover 400 around the axis of the axial flow fan 160. The water spraying effect of the water spray pipe 320 is realized by the high-speed air circulation near the axial flow fan 160, and there is no need to use other driving equipment to drive the condensed water in the water collecting tank 190, which further improves the overall energy-saving effect of the air conditioner.

[0084] Furthermore, the water spraying mechanism 300 further includes:

[0085] The rotating disk 340 is movably mounted on the cover 400;

[0086] A pushing mechanism, movably mounted on the connecting pipe 330, wherein the pushing mechanism is provided with a guide vane 350;

[0087] Among them, the cover shell 400 is provided with a first annular groove 410, and the rotating disk 340 is provided with a second annular groove 341. The first annular groove 410 and the second annular groove 341 form a circulation channel, and the circulation channel is connected between the second water pipe 310 and the connecting pipe 330. The rotating disk 340 and the cover shell 400 are sealed and movably connected.

[0088] By installing the water spray pipe 320 and the connecting pipe 330 on the rotating disk 340, the rotating disk 340 is movably installed on the cover 400, and the guide vane 350 is installed and connected to the connecting pipe 330. When the air flow generated by the axial flow fan acts on the guide vane 350, it can push the guide vane 350 and the rotating disk 340 to rotate around the axis. Controlling the rotation of the water spray pipe 320 can achieve the effect of splashing condensed water onto a larger area of ​​the condenser 120, thereby improving the cooling efficiency of the condenser 120. The rotating disk 340 is driven without other power, thereby further improving the energy-saving effect. The circulation channel is formed by the first annular groove 410 and the second annular groove 341, which facilitates the flow of condensed water in the second water pipe 310 to the connecting pipe 330, thereby ensuring the circulation of the connecting pipe 330.

[0089] Embodiment 3:

[0090] like Figure 2 , Figure 3As shown, the embodiment of the present application provides a cold air conditioner with energy-saving adjustment, which, in addition to the above technical features, further includes:

[0091] A second pre-cooling mechanism 500 is disposed at the first air inlet 170 , and the second pre-cooling mechanism 500 includes a second heat exchange tube 510 and a second heat exchange guide 520 ;

[0092] A third water pipe 530 connected to the second heat exchange pipe 510;

[0093] The solenoid valve 600 is installed on the second water pipe 310;

[0094] The control valve 700 is disposed on the chassis housing 100 and connected to the second water conduit 310;

[0095] A drain pipe 800 connected to the control valve 700, the drain pipe 800 is placed at the lower end of the control valve 700, and the opening of the drain pipe 800 is lower than the bottom of the sump 190;

[0096] The first water conduit 230 , the second water conduit 310 , and the third water conduit 530 are all connected to the solenoid valve 600 .

[0097] The second pre-cooling mechanism 500 is installed at the first air inlet 170, which is further outside than the evaporator 130. When the indoor temperature drops to a preset value, the air conditioner will reduce or shut down the power of the compressor 110, but the axial flow fan will still maintain a low speed to supply air. The second pre-cooling mechanism 500 can keep the indoor temperature for a longer time, slow down the start-up time of the compressor 110, and further improve the energy-saving effect. The third water pipe 530 is connected to the second heat exchange pipe 510 to facilitate the transportation of condensed water to the second heat exchange pipe 510. The second heat exchange pipe 510 and the second heat exchange guide 520 are used for heat exchange when the indoor air flows. The solenoid valve 600 controls the flow after flowing out of the water collection tank 190. The solenoid valve 600 adopts a three-position six-way valve. Valve 700 controls the condensed water in the water collection tank 190 to flow directly to the condenser 120, controls the condensed water in the water collection tank 190 to flow to the first pre-cooling mechanism 200 first and then to the condenser 120, controls the condensed water in the water collection tank 190 to flow to the second pre-cooling mechanism 500 first and then to the drain pipe 800, and controls the condensed water in the water collection tank 190 to flow directly to the drain pipe 800. When the working power of the fan motor 140 decreases or is turned off, the condensed water in the water collection tank 190 cannot be further extracted through the water spray pipe 320. Since the pipe mouth of the drain pipe 800 is lower than the water collection tank 190, a siphon effect can be achieved through the drain pipe 800, so that the water flow automatically flows out of the water collection tank 190, which is convenient for the water flow in the second heat exchange tube 510 to pass through, and the condensed water in the water collection tank 190 is discharged after the air conditioner stops working.

[0098] Embodiment 4:

[0099] like Figure 4-Figure 6 As shown, the embodiment of the present application provides a cold air conditioner with energy-saving adjustment. In addition to the above technical features, the rotating disk 340 further includes:

[0100] The first active chamber 342 is placed on the rotating disk 340;

[0101] A first piston 343 is disposed in the first movable chamber 342 and connected to the connecting pipe 330;

[0102] A first spring 344 is disposed in the first movable chamber 342 and abuts against the first piston 343;

[0103] The second active chamber 345 is placed on the rotating disk 340;

[0104] A second piston 346 is mounted on the rotating disk 340 and cooperates with the second movable chamber 345 . The second piston 346 is provided with a toggle groove 348 adapted to the guide vane 350 .

[0105] A second spring 347 acts on the second piston 346;

[0106] The connecting protrusion 360 is disposed on the rotating disk 340. The connecting protrusion 360 is provided with a ventilation channel 361. The ventilation channels 361 are respectively located on both sides of the connecting protrusion 360. The ventilation channels 361 are respectively connected to the first active cavity 342 and the second active cavity 345.

[0107] Among them, the chassis shell 100 is provided with an inflatable cylinder 900, and the inflatable cylinder 900 corresponds to the first active cavity 342 and the second active cavity 345 respectively. The connecting protrusion 360 is provided with a plurality of connecting holes 362 separately connected to the ventilation channel 361. The cover shell 400 is provided with a connecting seat 420 connected to the inflatable cylinder 900, and the connecting seat 420 is provided with a switch seat 421 corresponding to the connecting hole 362. The connecting seat 420 is provided with a movable limit seat 422, and the connecting protrusion 360 is provided with a limit portion 363 corresponding to the movable limit seat 422.

[0108] The connecting pipe 330 and the water spray pipe 320 are controlled to shrink in the radial direction of the rotating disk 340 by the first active chamber 342, the first piston 343, and the first spring 344. When the air conditioner is just started or the fan motor 140 is in a low-power working state, the connecting pipe 330 and the water spray pipe 320 are contracted and set. The deflection of the guide vane 350 is controlled by the second active chamber 345, the first piston 343, the toggle groove 348, and the second spring 347. The first active chamber 342 and the second active chamber 345 correspond to each other separately through the inflator 900. The sealing and active connection between the connecting protrusion 360, the switch seat 421, and the cover shell 400 is ensured to ensure the sealing stability of the ventilation channel 361 when the rotating disk 340 rotates. By setting a plurality of ventilation The channel 361, through the corresponding switch seat 421 and the connecting hole 362, enables the first active cavity 342 on the rotating disk 340 to be individually controlled, and the deflection of the guide vane 350 can be individually controlled. When the connecting tube 330 is extended, the rotation speed of the rotating disk 340 is adjusted by controlling the number of deflections of the guide vanes 350 on the connecting tube 330, thereby improving the convenience of energy-saving adjustment. The connecting seat 420 is used to connect the inflator 900 and the ventilation channel 361. The limit portion 363 is placed on the side of the connecting hole 362, and is positioned by the limit seat and the limit portion 363, so that the connecting seat 420, the switch seat 421 and the connecting hole 362 are conveniently adjusted accordingly, and the switch seat 421 is electromagnetically controlled.

[0109] Furthermore, the inflator 900 includes:

[0110] The movable rod 910 is provided with a third piston 920;

[0111] A fourth piston 930 is disposed in the inflator 900;

[0112] A third spring 940 is disposed between the fourth piston 930 and the inflator 900;

[0113] The control valve 700 includes a valve stem 710 , and a connecting member 950 is provided between the valve stem 710 and the movable rod 910 .

[0114] The movable rod 910, the valve stem 710, and the connecting piece 950 are installed and connected. The valve stem 710 is electromagnetically controlled. The movement of the valve stem 710 controls the movement of the movable rod 910. When the control valve 700 is controlled to be connected to the condenser 120, the space between the third piston 920 and the fourth piston 930 is compressed to facilitate the movement of the first piston 343 and the second piston 346. When the amount of movement of the first piston 343 and the second piston 346 is adjusted, the pressure stability in the inflatable cylinder 900 is maintained by the fourth piston 930 and the third spring 940. When the valve stem 710 and the movable rod 910 need to move together, compared with the general valve stem 710, its formation is increased, so that the control valve 700 has a certain chamber depth, so that when the control valve 700 is switched to the drain pipe 800 connection state, the drain pipe 800 can have an appropriate amount of water to facilitate the initial flow of the drain pipe 800 to form a siphon.

[0122] The present application also provides a method for regulating a cold air conditioner with energy-saving regulation, the specific steps of which include:

[0123] S1, when the air conditioner is started, the water spray pipe 320 is controlled to contract through the control valve 700, and the water spray pipe 320 is controlled to maintain the contracted state through the switch seat 421, and then the control valve 700 is switched back to the connected state of the water spray pipe 320, and the water collection tank 190 is now in the water storage stage;

[0124] S2, when the air conditioner has been working for a period of time and the water level in the water collection tank 190 reaches L1, the water spray pipe 320 is extended through the switch seat 421, and the solenoid valve 600 controls the second water pipe 310 to connect to the water collection tank 190, and the air quickly passes through the water spray pipe 320, and the condensed water in the water collection tank 190 is sprayed out from the water spray pipe 320;

[0125] S3, the air conditioner continues to work. When it is necessary to add fresh air from the outside, the solenoid valve 600 is controlled to connect the first heat exchange pipe 210, so that the condensed water first passes through the first heat exchange pipe 210 and then sprays out from the spray pipe 320;

[0126] S4, when the air conditioner works until the room temperature reaches a preset value, the compressor 110 will reduce the working efficiency or shut down directly, control the solenoid valve 600 to connect the second heat exchange pipe 510, control the control valve 700 to connect the drain pipe 800, and control the water spray pipe 320 to contract, so that the condensed water first passes through the second heat exchange pipe 510 and then is discharged from the drain pipe 800. When the compressor 110 works normally, switch the control valve 700 back to the connection state of the water spray pipe 320, and control the solenoid valve 600 to disconnect the connection with the second heat exchange pipe 510;

[0127] S5, when the air conditioner is turned off or the water level in the water collection tank 190 exceeds L2, the control valve 700 is controlled to connect to the drain pipe 800. When the water level in the water collection tank 190 exceeds L2 and the air conditioner is in working state, the water in the water collection tank 190 is controlled to be drained to L1. When the air conditioner is turned off, the condensed water in the water collection tank 190 is drained.

[0128] There are four situations in which the condensed water generated by the air conditioner flows. When the air compressor is working, the condensed water flows directly to the condenser 120, thereby improving the cooling efficiency of the condenser 120; when the air conditioner is used to add fresh air, the condensed water first flows to the first pre-cooling mechanism 200 and then flows to the condenser 120. By pre-cooling the fresh air, the pressure of the overall power increase of the air conditioner is reduced when fresh air is added; when the indoor temperature reaches the preset value, the compressor 110 stops working, the fan motor 140 stops or works at low power, and the condensed water first flows to the second pre-cooling mechanism 500 and then flows to the drain pipe 800, so that the indoor temperature is maintained for a longer time, thereby improving the energy-saving effect; when the air conditioner is turned off, the condensed water flows directly to the drain pipe 800, and the water in the sump 190 is discharged. By providing utilization rate for the condensed water and without the need for additional equipment to transport and drive the condensed water, a higher energy-saving effect is achieved.
