Detailed implementation manners

[0018] Embodiments of the present invention will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention will be described in detail below.

[0019] In this application, the air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes, involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

[0020] The compressor compresses the refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0021] The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by using the latent heat of evaporation of the refrigerant to perform heat exchange with the material to be cooled. Throughout the cycle, the air conditioner can adjust the temperature of the indoor space.

[0022] The outdoor unit of the air conditioner refers to the part of the refrigeration cycle including the compressor and the outdoor heat exchanger. The indoor unit of the air conditioner includes the indoor heat exchanger, and the expansion valve can be provided in the indoor unit or the outdoor unit.

[0023] The indoor heat exchanger and the outdoor heat exchanger serve as condensers or evaporators. When the indoor heat exchanger serves as a condenser, the air conditioner serves as a heater in the heating mode. When the indoor heat exchanger serves as an evaporator, the air conditioner serves as a cooler in the cooling mode.

[0024] The following refers to Figures 1 - 7Describe an air conditioner 10 according to an embodiment of the present invention, including: a compressor 100, a four-way valve 200, a first heat exchanger assembly 300, a throttling device 400, and a second heat exchanger assembly 500.

[0025] Specifically, the compressor 100 is used to drive the refrigerant to circulate. An air inlet 101 and an air outlet 102 are respectively provided at both ends of the compressor 100; a first valve port 201, a second valve port 202, a third valve port 203, and a fourth valve port 204 are circumferentially arranged on the four-way valve 200. The second valve port 202 is communicated with the air inlet 101, and the fourth valve port 204 is communicated with the air outlet 102; one end of the first heat exchanger assembly 300 is communicated with the third valve port 203, and the refrigerant exchanges heat on the first heat exchanger assembly 300; the throttling device 400 is communicated with the other end of the first heat exchanger assembly 300, and the throttling device 400 is configured to throttle and boost the passing refrigerant; one end of the second heat exchanger assembly 500 is communicated with the throttling device 400, and the other end of the second heat exchanger assembly 500 is communicated with the first valve port 201, and the refrigerant exchanges heat in the second heat exchanger assembly 500.

[0026] That is to say, in a specific embodiment, the air conditioner 10 is adapted to include: a compressor 100, a four-way valve 200, a first heat exchanger assembly 300, a throttling device 400, and a second heat exchanger assembly 500. During the use of the air conditioner 10, it is adapted to let the compressor 100 provide a driving effect to drive the refrigerant to circulate, and the refrigerant is adapted to be introduced into the four-way valve 200 to introduce the refrigerant into the first heat exchanger assembly 300 or the second heat exchanger assembly 500 according to the use situation of the air conditioner 10 to form a cooling or heating mode of the air conditioner 10, so that the air conditioner 10 can be used according to the design to improve the indoor environment, thereby making the user's experience of using the air conditioner 10 more comfortable.

[0027] After the refrigerant exchanges heat, it is adapted to be introduced into the throttling device 400 for throttling and boosting, so that the subsequent refrigerant can be introduced into the subsequent first heat exchanger assembly 300 and second heat exchanger assembly 500 for heat exchange, thereby realizing the performance composition of the air conditioner 10.

[0028] Moreover, a first heat exchange area 301 and a second heat exchange area 302 are spaced apart on the first heat exchanger assembly 300. The first heat exchanger assembly 300 has an operating state and a cleaning state. When the first heat exchanger assembly 300 is in the operating state, the refrigerant flows through after passing through the first heat exchange area 301 and the second heat exchange area 302; when the first heat exchanger assembly 300 is in the cleaning state, the refrigerant selectively flows through at least one of the first heat exchange area 301 and the second heat exchange area 302 and then circulates; wherein, the cleaning state has a first stage and a second stage; when in the first stage, the first heat exchange area 301 and the second heat exchange area 302 are arranged in series; when in the second stage, the first heat exchange area 301 and the second heat exchange area 302 are arranged in parallel.

[0029] That is to say, during the use of the first heat exchanger assembly 300, it is suitable to have two usage situations, namely the operating state and the cleaning state. When the first heat exchanger assembly 300 is in the operating state, the refrigerant flows through after passing through the first heat exchange area 301 and the second heat exchange area 302 for normal use, while when the first heat exchanger assembly 300 is in the cleaning state, the refrigerant flows through at least one of the first heat exchange area 301 and the second heat exchange area 302 for cleaning use. Specifically, during the cleaning process of the first heat exchanger assembly 300, it is suitable to include a first stage and a second stage. During the first stage, the refrigerant is suitable to dissipate heat through the first heat exchange area 301 and then absorb heat in the second heat exchange area 302 to condense moisture on the second heat exchange area 302, and then during the second stage, the refrigerant is suitable to melt and evaporate the condensed moisture to carry away dust for cleaning. At the same time, during the first stage and the second stage, at least another part of the heat exchanger is working normally. In this way, during the cleaning use process of the air conditioner 10, it can still have a certain performance output to meet the use of the air conditioner.

[0030] According to the air conditioner 10 of the embodiment of the present invention, by arranging the first heat exchange area 301 and the second heat exchange area 302 on the first heat exchanger assembly 300, the air conditioner 10 can selectively control the first heat exchange area 301 and the second heat exchange area 302 to be arranged in parallel or in series during use, so that the air conditioner 10 can perform a cleaning function during use, and at the same time, it can still have a certain performance output to meet the use requirements of the air conditioner 10, so as to improve the user experience of using the air conditioner 10.

[0031] In some specific embodiments, the first heat exchanger assembly 300 includes: a heat exchanger 310, a plurality of front three-way valves 330, and a plurality of rear three-way valves 340. The heat exchanger 310 is provided with a plurality of parallel circulation channels 320; a plurality of front three-way valves 330 are all communicated with the third valve port 203. The plurality of front three-way valves 330 correspond to the plurality of circulation channels 320 one by one, and the plurality of front three-way valves 330 are arranged at one end of the circulation channels 320; a plurality of rear three-way valves 340 are all communicated with the throttling device 400. The plurality of rear three-way valves 340 correspond to the plurality of circulation channels 320 one by one, and the plurality of rear three-way valves 340 are arranged at the other end in the circulation channels 320, and one of the plurality of front three-way valves 330 is communicated with one of the plurality of rear three-way valves 340; when the first heat exchanger assembly 300 performs heat exchange, the first heat exchanger assembly 300 performs a cleaning process while maintaining the current operating performance. It can be understood that the first heat exchanger assembly 300 is adapted to include a heat exchanger 310, a plurality of front three-way valves 330, and a plurality of rear three-way valves 340. When the first heat exchanger assembly 300 is adapted to include a heat exchanger 310, a plurality of front three-way valves 330, and a plurality of rear three-way valves 340, during the circulation process of the refrigerant, the refrigerant is adapted to be introduced into the heat exchanger 310 for heat exchange to constitute the output performance of the air conditioner 10.

[0032] Specifically, the heat exchanger 310 is adapted to be constructed with parallel circulation channels 320, so that when the refrigerant is introduced into the heat exchanger 310, it is adapted to circulate in series or in parallel, so as to sequentially pass through two circulation channels 320, or simultaneously enter into two circulation channels 320. When the refrigerant sequentially passes through two circulation channels 320, it is adapted to perform better heat exchange on the heat exchanger 310. As a result, after the heat exchanger 310 performs heat exchange, frost forms on the heat exchanger 310. After the frost forms, it is adapted to adjust the circulation mode of the refrigerant, so that the refrigerant directly enters the heat exchanger 310 simultaneously to dissipate heat, so that the heat can melt the condensed moisture, so that the melted moisture can synchronously carry away the frost on the heat exchanger 310, thereby realizing the cleaning function of the heat exchanger 310.

[0033] Among them, when the air conditioner 10 is in the cleaning mode for one of the plurality of circulation channels 320, it includes: the first stage: the refrigerant enters into the plurality of circulation channels 320 after passing through one of the plurality of front three-way valves 330, and is transferred to one of the plurality of rear three-way valves 340 and then transferred to another one of the plurality of front three-way valves 330, and then transferred to another one of the plurality of circulation channels 320, and then passes through another one of the plurality of rear three-way valves 340 and is transferred into the throttling device 400 for circulation; the second stage: the refrigerant enters into the corresponding circulation channel 320 after passing through the plurality of front three-way valves 330, and is transferred to the throttling device 400 through the corresponding rear three-way valve 340 to complete the cleaning.

[0034] That is to say, when the air conditioner 10 is in the cleaning mode for the heat exchanger 310, it is suitable to clean one of the multiple circulation flow paths 320. After one of the multiple circulation flow paths 320 is cleaned, another one of the multiple circulation flow paths 320 is cleaned. After all the multiple circulation flow paths 320 are cleaned, the cleaning effect is stopped.

[0035] Specifically, when the air conditioner 10 cleans another one of the multiple circulation flow paths 320, it is suitable to let the refrigerant enter one of the multiple circulation flow paths 320 for heat exchange, and then absorb heat on another one of the multiple circulation flow paths 320, so that frost can condense on another one of the multiple circulation flow paths 320 to complete the first stage. Then it enters the second stage. In the second stage, heat dissipation occurs on another one of the multiple circulation flow paths 320 to melt the condensed frost, so that the melted water can carry away the dust on the circulation flow path 320, thereby realizing the removal of the dust on the circulation flow path 320 and the cleaning effect on the circulation flow path 320. At the same time, when cleaning another one of the multiple circulation flow paths 320, one of the multiple circulation flow paths 320 can perform heat exchange according to the previous operation requirements of the air conditioner 10, so that the multiple circulation flow paths 320 can output performance according to the previous operation mode. When the air conditioner 10 is in the cleaning mode, the air conditioner 10 can still perform a certain amount of performance output, so as to realize the non-stop cleaning effect of the air conditioner 10.

[0036] In some embodiments, the multiple circulation flow paths 320 include a first flow path 321 and a second flow path 322 arranged in parallel. The air conditioner 10 cleaning the first flow path 321 includes: the refrigerant enters into the multiple first flow paths 321 after passing through one of the multiple front three-way valves 330, and is transferred to one of the multiple rear three-way valves 340 and then transferred to another one of the multiple front three-way valves 330, and then transferred into the multiple second flow paths 322, and then passes through another one of the multiple rear three-way valves 340 and is transferred into the throttling device 400 for circulation; the refrigerant enters into the first flow path 321 after passing through the three-way valve 330, and is transferred into the three-way valve 340, and then transferred into the throttling device 400 for circulation, and the refrigerant enters into the second flow path 322 after passing through the three-way valve 330, and is transferred into the three-way valve 340, and then transferred into the throttling device 400 for circulation.

[0037] In this way, by making the first flow path 321 and the second flow path 322 suitable to be constructed on the circulating flow path 320, the first flow path 321 and the second flow path 322 are arranged in parallel, so that the refrigerant can be sequentially introduced into the first flow path 321 or the second flow path 322 according to the control, so that the refrigerant can be used according to the design. At the same time, when the refrigerant is introduced into another circulating flow path 320, frost can be condensed on the circulating flow path 320 to facilitate subsequent melting and realize the cleaning function of the air conditioner 10. For example, when the refrigerant is introduced into the first flow path 321 for heat dissipation, and then introduced into the throttling device 400 for throttling and boosting, and then the refrigerant is introduced into the second flow path 322 for heat absorption, so that frost can be condensed on the second flow path 322. In this way, during the use of the air conditioner 10, the first flow path 321 is suitable for constituting the output performance of the air conditioner 10, and the second flow path 322 is suitable for condensing frost for cleaning. Then, the refrigerant is suitable to be introduced into the first flow path 321 and the second flow path 322 together. When the refrigerant is introduced into the first flow path 321, it is suitable for constituting the output performance of the air conditioner 10 together, and when the refrigerant is incorporated into the second flow path 322, it is suitable for releasing heat to melt the frost on the second flow path 322, so as to take away the dust on the second flow path 322 and realize the cleaning function of the second flow path 322. Similarly, when cleaning the first flow path 321, the process is similar to the above-mentioned flow process. When the refrigerant is introduced into the second flow path 322 for heat dissipation, and then introduced into the throttling device 400 for throttling and boosting, and then the refrigerant is introduced into the first flow path 321 for heat absorption, so that frost can be condensed on the first flow path 321. In this way, during the use of the air conditioner 10, the second flow path 322 is suitable for constituting the output performance of the air conditioner 10, and the first flow path 321 is suitable for condensing frost for cleaning. Then, the refrigerant is suitable to be introduced into the first flow path 321 and the second flow path 322 together. When the refrigerant is introduced into the second flow path 322, it is suitable for constituting the output performance of the air conditioner 10 together, and when the refrigerant is incorporated into the first flow path 321, it is suitable for releasing heat to melt the frost on the first flow path 321, so as to take away the dust on the first flow path 321 and realize the cleaning function of the first flow path 321. In this way, during the use of the air conditioner 10, a part of the circulating flow path 320 can maintain performance output while the other part performs the cleaning function, so that the air conditioner 10 can achieve non-stop operation and cleaning function.

[0038] In some embodiments, the first heat exchanger assembly 300 further includes: a connection valve 350, and the connection valve 350 is connected between one of the plurality of first three-way valves 330 and one end of the plurality of circulating flow paths 320.

[0039] It can be understood that the first heat exchanger assembly 300 is also adapted to include a connection valve 350, which has multiple usage states, at least including a direct-through state and a throttling state. When the connection valve 350 is in the direct-through state, it is adapted to allow the refrigerant to flow directly, and when the connection valve 350 is in the throttling state, it is adapted to throttle and boost the refrigerant, so that when the subsequent refrigerant flows through the circulation flow path 320, it can absorb heat to condense ice and frost, thereby enabling subsequent cleaning.

[0040] In some embodiments, the first three-way valve 330 includes: a first three-way valve 331 and a second three-way valve 332. One end of the first three-way valve 331 is communicated with the third valve port 203, and the other end of the first three-way valve 331 is communicated with one end of the first flow path 321; the second three-way valve 332 is arranged at an interval from the first three-way valve 331, and one end of the second three-way valve 332 is communicated with the third valve port 203, and the other end of the second three-way valve 332 is communicated with one end of the second flow path 322; the latter three-way valve 340 includes: a third three-way valve 341 and a fourth three-way valve 342. One end of the third three-way valve 341 is communicated with the throttling device 400, the other end of the third three-way valve 341 is communicated with the other end of the first flow path 321, and the third end of the third three-way valve 341 is communicated with the third end of the second three-way valve 332; the fourth three-way valve 342 is arranged at an interval from the third three-way valve 341, and one end of the fourth three-way valve 342 is communicated with the throttling device 400, the other end of the fourth three-way valve 342 is communicated with the other end of the second flow path 322, and the third end of the fourth three-way valve 342 is connected to the third end of the first three-way valve 331.

[0041] It can be understood that the first three-way valve 330 is adapted to be constructed at the input ends of the first flow path 321 and the second flow path 322, and the latter three-way valve 340 is adapted to be constructed at the output ends of the first flow path 321 and the second flow path 322. Specifically, the first three-way valve 330 is adapted to include a first three-way valve 331 and a second three-way valve 332. The first three-way valve 331 is constructed at the input end of the first flow path 321, and the second three-way valve 332 is constructed at the input end of the second flow path 322. The latter three-way valve 340 is adapted to include a third three-way valve 341 and a fourth three-way valve 342. The third three-way valve 341 is constructed at the output end of the first flow path 321, and the fourth three-way valve 342 is constructed at the output end of the second flow path 322. In this way, when controlling the performance output of the first flow path 321 and the second flow path 322, it is adapted to control the communication conditions of the first three-way valve 331, the second three-way valve 332, the third three-way valve 341, and the fourth three-way valve 342, so as to realize the performance output of a part of the circulation flow path 320 in the air conditioner 10 and the cleaning function of another part of the circulation flow path 320, so as to constitute the non-stop cleaning performance function of the air conditioner 10, so as to maintain and improve the user experience when using the air conditioner 10.

[0042] In some embodiments, the first three-way valve 331, the second three-way valve 332, the third three-way valve 341, and the fourth three-way valve 342 each include: a valve body 361, a pull rod 364, a driving member 365, and a sealing ring 366. An inner cavity 362 is formed in the valve body 361. Three valve ports 363 are provided on the valve body 361 at intervals, and the horizontal heights of the three valve ports 363 are different. The pull rod 364 is disposed in the inner cavity 362, and the pull rod 364 moves along the inner cavity 362 to block one of the three valve ports 363. The driving member 365 is disposed outside the valve body 361, and the driving member 365 is used to drive the pull rod 364 to move. The sealing ring 366 is sleeved inside one end of the pull rod 364, and the sealing ring 366 abuts against the inner peripheral wall of the inner cavity 362.

[0043] It can be understood that the first three-way valve 331, the second three-way valve 332, the third three-way valve 341, and the fourth three-way valve 342 are set to have the same three-way valve structure, so that the first three-way valve 331, the second three-way valve 332, the third three-way valve 341, and the fourth three-way valve 342 can be interchanged during the assembly process, thereby reducing the production cost, improving the assembly efficiency, and having high versatility for subsequent maintenance and repair, and improving the service life.

[0044] Specifically, the first three-way valve 331, the second three-way valve 332, the third three-way valve 341, and the fourth three-way valve 342 are all adapted to include: a valve body 361, a pull rod 364, a driving member 365, and a sealing ring 366. The valve body 361 is adapted to form an inner cavity 362 for accommodating other structures to protect the other structures. Three valve ports 363 are adapted to be spaced apart on the valve body 361, so that during the use of the three-way valve, it is determined that only two of the valve ports 363 are connected to achieve refrigerant transfer, and adjusting the opening in the middle can achieve throttling and pressurization of the refrigerant. In order to facilitate the flow of the refrigerant, the horizontal heights of the three valve ports 363 are adapted to be different. A pull rod 364 is adapted to be constructed in the inner cavity 362, and the pull rod 364 is adapted to move along the inner cavity 362. When the pull rod 364 is at the highest position, it is adapted to block the highest valve port 363 to connect the remaining two valve ports 363, and when the pull rod 364 is at the lowest position, it is adapted to block the lowest valve port 363 to connect the remaining two valve ports 363. In this way, by adjusting the pull rod 364, different performance selections of the three-way valve can be achieved, so that the heat exchanger 310 can achieve the non-stop cleaning function of the air conditioner 10 by controlling the use states of different three-way valves. At the same time, a driving member 365 is also provided at one end of the pull rod 364. The driving member 365 is adapted to adjust the driving action according to requirements to drive the pull rod 364 to adjust its position, so as to achieve different height adjustments and different output performances of the three-way valve. Moreover, in order to make the structure blocked by the pull rod 364 have higher sealing performance, a sealing ring 366 is adapted to be constructed at the end of the pull rod 364 that moves in the inner cavity 362 to improve the sealing performance, so that the refrigerant can flow according to the design to achieve the cleaning function of the heat exchanger 310.

[0045] In some embodiments, the first three-way valve 331, the second three-way valve 332, the third three-way valve 341, and the fourth three-way valve 342 further include: a spring 367. The spring 367 is disposed at one end of the pull rod 364, and the spring 367 is used to drive the pull rod 364 to be in the lowest position. It can be understood that the spring 367 is adapted to drive the pull rod 364 to reset, so that the spring 367 can drive the pull rod 364 to be in the lowest position so that the three-way valve can be in a direct-through state for the heat exchanger 310 to perform heat exchange processing, so that the air conditioner 10 can be better maintained in the performance output when not being cleaned, making the use of the air conditioner 10 more reliable.

[0046] In some embodiments, the connection valve 350 includes: a first connection valve 351 and a second connection valve 352. The first connection valve 351 is connected between the first three-way valve 331 and the first flow path 321, and the second connection valve 352 is connected between the second three-way valve 332 and the second flow path 322.

[0047] That is to say, the connection valve 350 is adapted to include a first connection valve 351 and a second connection valve 352. The first connection valve 351 is adapted to be connected between the first three-way valve 331 and the first flow path 321, and the second connection valve 352 is adapted to be connected between the second three-way valve 332 and the second flow path 322, so that the first connection valve 351 and the second connection valve 352 can be selected for different usage performances according to requirements. For example, when the second flow path 322 reaches the first stage, the refrigerant enters the first flow path 321 through the first three-way valve 331. At this time, the first connection valve 351 is in a normally open state. After the refrigerant exchanges heat through the first flow path 321, it is adapted to pass through the third three-way valve 341 to the second three-way valve 332, and then through the second connection valve 352. The second connection valve 352 is in a throttling state, so that the refrigerant passing through it increases, so that when the refrigerant subsequently enters the second flow path 322, it can absorb heat to condense ice on the second flow path 322, so as to facilitate the melting of the ice when the subsequent refrigerant is introduced into the second flow path 322 for heat dissipation, so as to realize the cleaning function of the second flow path 322. At the same time, when the second flow path 322 is being cleaned, the first flow path 321 can dissipate heat, so as to constitute the performance output of the air conditioner 10, so that a certain performance output can be realized while cleaning, so that the air conditioner 10 can realize the cleaning function without stopping during use. Not only that, when the second flow path 322 reaches the second stage, both the first connection valve 351 and the second connection valve 352 are in a normally open state, so that the refrigerant can exchange heat through the first flow path 321 and the second flow path 322, so that the refrigerant is adapted to exchange heat when passing through the first flow path 321 to constitute the output performance of the air conditioner 10, and the refrigerant is adapted to exchange heat when passing through the second flow path 322 to melt the ice on the second flow path 322, so that the melted ice can take away the dust on the second flow path 322, so as to realize the cleaning function of the second flow path 322. At this time, the first flow path 321 can also perform the performance output required by the air conditioner 10, so that the air conditioner 10 can maintain a certain performance output without stopping during use while also performing the cleaning function. Similarly, when the first flow path 321 reaches the first stage, the refrigerant enters the first flow path 321 through the second three-way valve 332. At this time, the second connection valve 352 is in a normally open state. After the refrigerant exchanges heat through the second flow path 322, it is adapted to pass through the fourth three-way valve 342 to the first three-way valve 331, and then through the first connection valve 351. The first connection valve 351 is in a throttling state, so that the refrigerant passing through it increases, so that when the refrigerant subsequently enters the first flow path 321, it can absorb heat to condense ice on the first flow path 321, so as to facilitate the melting of the ice when the subsequent refrigerant is introduced into the first flow path 321 for heat dissipation, so as to realize the self-cleaning function of the first flow path 321.Meanwhile, when cleaning the first flow path 321, heat dissipation can be achieved through the second flow path 322 to constitute the performance output of the air conditioner 10, so that a certain performance output can be realized during cleaning, enabling the air conditioner 10 to perform cleaning without shutting down during use. Moreover, when the first flow path 321 reaches the second stage, both the first connection valve 351 and the second connection valve 352 are in a normally open state, allowing the refrigerant to exchange heat through the first flow path 321 and the second flow path 322. When the refrigerant passes through the second flow path 322 for transfer, it is suitable for heat exchange to constitute the output performance of the air conditioner 10, while when the refrigerant passes through the first flow path 321 for transfer, it is suitable for heat exchange to melt the frost on the first flow path 321, enabling the melted frost to carry away the dust on the first flow path 321, thus achieving the cleaning effect on the second flow path 322. At this time, the second flow path 322 can also perform the performance output required by the air conditioner 10, enabling the air conditioner 10 to maintain a certain performance output without shutting down during use while also being able to perform the cleaning function.

[0048] In some embodiments, both the first connection valve 351 and the second connection valve 352 are expansion valves with adjustable opening degrees. It can be understood that both the first connection valve 351 and the second connection valve are configured as expansion valves with adjustable opening degrees, so that the first connection valve 351 and the second connection valve 352 are suitable for adjusting the opening degree according to requirements, enabling the throttling performance of the first connection valve 351 and the second connection valve 352 to be adjusted according to requirements during use, so that the first heat exchanger assembly 300 can obtain a better cleaning effect, and enabling the air conditioner 10 to perform a more efficient cleaning function without shutting down.

[0049] In some embodiments, when the air conditioner 10 is in the first stage of the cleaning mode for the first flow path 321, the first stage maintenance time is T1, and the time T1 satisfies the relationship: 5 min ≤ T1 ≤ 30 min. That is to say, during the first stage of cleaning, it is suitable to maintain for a certain time to allow sufficient frost to condense on the circulating flow path 320 for subsequent melting, so as to improve the cleaning effect in the cleaning mode.

[0050] An air conditioner 10 according to an embodiment of the present invention includes: a compressor 100, a four-way valve 200, a first heat exchanger assembly 300, a throttling device 400, and a second heat exchanger assembly 500. The compressor 100 is used to drive the refrigerant to circulate. An air inlet 101 and an air outlet 102 are respectively provided at both ends of the compressor 100. The first valve port 201, the second valve port 202, the third valve port 203, and the fourth valve port 204 are circumferentially arranged on the four-way valve 200. The second valve port 202 is communicated with the air inlet 101, and the fourth valve port 204 is communicated with the air outlet 102. One end of the first heat exchanger assembly 300 is communicated with the third valve port 203, and the refrigerant exchanges heat on the first heat exchanger assembly 300. The throttling device 400 is communicated with the other end of the first heat exchanger assembly 300, and the throttling device 400 is configured to throttle and boost the refrigerant passing through. One end of the second heat exchanger assembly 500 is communicated with the throttling device 400, and the other end of the second heat exchanger assembly 500 is communicated with the first valve port 201, and the refrigerant exchanges heat in the second heat exchanger assembly 500. The first heat exchanger assembly 300 includes: a heat exchanger 310, a first three-way valve 331, a second three-way valve 332, a third three-way valve 341, and a fourth three-way valve 342. A first flow path 321 and a second flow path 322 are provided side by side on the heat exchanger 310. One end of the first three-way valve 331 is communicated with the third valve port 203, and the other end of the first three-way valve 331 is communicated with one end of the first flow path 321. The second three-way valve 332 is arranged at an interval from the first three-way valve 331, and one end of the second three-way valve 332 is communicated with the third valve port 203, and the other end of the second three-way valve 332 is communicated with one end of the second flow path 322. One end of the third three-way valve 341 is communicated with the throttling device 400, and the other end of the third three-way valve 341 is communicated with the other end of the first flow path 321. The third end of the third three-way valve 341 is communicated with the third end of the second three-way valve 332. The fourth three-way valve 342 is arranged at an interval from the third three-way valve 341, and one end of the fourth three-way valve 342 is communicated with the throttling device 400, and the other end of the fourth three-way valve 342 is communicated with the other end of the second flow path 322. The third end of the fourth three-way valve 342 is connected to the third end of the first three-way valve 331. When the first heat exchanger assembly 300 exchanges heat, the first heat exchanger assembly 300 adjusts the usage states of the first three-way valve 331, the second three-way valve 332, the third three-way valve 341, and the fourth three-way valve 342, so that the first heat exchanger assembly 300 performs cleaning treatment while maintaining the current operating performance.

[0051] It can be understood that during the operation of the air conditioner 10 in this application, the air conditioner 10 is adapted to include: a compressor 100, a four-way valve 200, a first heat exchanger assembly 300, a throttling device 400, and a second heat exchanger assembly 500. During the use of the air conditioner 10, the compressor 100 is adapted to provide a driving effect to drive the refrigerant to circulate, and the refrigerant is adapted to be introduced into the four-way valve 200 to introduce the refrigerant into the first heat exchanger assembly 300 or the second heat exchanger assembly 500 according to the usage of the air conditioner 10 to form a cooling or heating mode of the air conditioner 10, so that the air conditioner 10 can be used as designed to improve the indoor environment, thereby making the user's experience of using the air conditioner 10 more comfortable.

[0052] After the refrigerant exchanges heat, it is adapted to be introduced into the throttling device 400 for throttling and pressure boosting, so that the subsequent refrigerant can be introduced into the subsequent first heat exchanger assembly 300 and the second heat exchanger assembly 500 for heat exchange, thereby realizing the performance composition of the air conditioner 10.

[0053] Specifically, the heat exchanger 310 is adapted to be constructed with parallelly arranged circulation paths 320, so that when the refrigerant is introduced into the heat exchanger 310, it is adapted to circulate in series or in parallel, so as to pass through the two circulation paths 320 in sequence, or enter the two circulation paths 320 simultaneously. When the refrigerant passes through the two circulation paths 320 in sequence, it is adapted to perform better heat exchange on the heat exchanger 310, so that after the heat exchanger 310 exchanges heat, frost forms on the heat exchanger 310. After the frost forms, it is adapted to adjust the circulation mode of the refrigerant so that the refrigerant directly enters the heat exchanger 310 simultaneously to dissipate heat, so that the heat can melt the condensed moisture, so that the melted moisture can synchronously carry away the frost on the heat exchanger 310, thereby realizing the cleaning function of the heat exchanger 310.

[0054] That is to say, when the air conditioner 10 is in the cleaning mode for the heat exchanger 310, it is adapted to clean one of the multiple circulation paths 320. After one of the multiple circulation paths 320 is cleaned, clean another one of the multiple circulation paths 320. After all the multiple circulation paths 320 are cleaned, stop the cleaning function.

[0055] Specifically, when the air conditioner 10 cleans another one of the multiple circulation flow paths 320, it is suitable to allow the refrigerant to pass through one of the multiple circulation flow paths 320 for heat exchange, and then absorb heat when on another one of the multiple circulation flow paths 320, so that frost can condense on another one of the multiple circulation flow paths 320 to complete the first stage. Then it enters the second stage. In the second stage, heat dissipation occurs on another one of the multiple circulation flow paths 320 to melt the condensed frost, so that the melted water can carry away the dust on the circulation flow path 320, thereby realizing the removal of the dust on the circulation flow path 320 and achieving the cleaning effect on the circulation flow path 320. At the same time, when cleaning another one of the multiple circulation flow paths 320, one of the multiple circulation flow paths 320 can perform heat exchange according to the previous operating requirements of the air conditioner 10, so that the multiple circulation flow paths 320 can output performance according to the previous operating mode. When the air conditioner 10 is in the cleaning mode, the air conditioner 10 can still output a certain amount of performance, so as to realize the non-stop cleaning function of the air conditioner 10.

[0056] When the cleaning mode needs to be carried out, for example, when cleaning the second flow path 322, it is suitable to allow the first flow path 321 to output the performance required by the air conditioner 10. Therefore, it is suitable to pass the refrigerant through the first three-way valve 331 to the first connection valve 351. At this time, the first connection valve 351 has a direct flow. Then it is suitable to pass through the first flow path 321 for heat exchange to constitute the output performance of the heat exchanger 310 and be transmitted to the third three-way valve 341. Then it enters the second connection valve 352 after passing through the second three-way valve 332. At this time, the second connection valve 352 throttles, so that the refrigerant entering the second flow path 322 absorbs heat to condense frost on the second flow path 322, and then is transmitted to the structural device through the fourth three-way valve 342 for subsequent use. After condensing for a period of time, it is suitable to adjust the flow direction of the three-way valve so that the refrigerant passes through the first three-way valve 331 to the first connection valve 351. At this time, the first connection valve 351 has a direct flow. Then it is suitable to pass through the first flow path 321 for heat exchange to constitute the output performance of the heat exchanger 310 and be transmitted to the throttling device 400 through the third three-way valve 341. At this time, the refrigerant can also pass through the second three-way valve 332 to the second connection valve 352. At this time, the second connection valve 352 has a direct flow. Then it is suitable to pass through the second flow path 322 for heat exchange to melt the frost condensed on the second flow path 322, and then be transmitted to the throttling device 400 through the fourth three-way valve 342 to complete the refrigerant cycle of the air conditioner 10.

[0057] Similarly, when cleaning the first flow path 321, it is suitable to let the second flow path 322 perform the performance output required by the air conditioner 10. Therefore, the refrigerant is suitable to be introduced into the second connection valve 352 after passing through the second three-way valve 332. At this time, the second connection valve 352 is in a direct-flow state, and then it is suitable to be introduced into the second flow path 322 for heat exchange to constitute the output performance of the heat exchanger 310, and then transmitted to the fourth three-way valve 342. After that, it enters the first connection valve 351 after passing through the first three-way valve 331. At this time, the first connection valve 351 throttles, so that the refrigerant entering the first flow path 321 absorbs heat to condense frost on the first flow path 321, and then is transmitted to the structural device through the third three-way valve 341 for subsequent use. After condensing for a period of time, it is suitable to adjust the flow direction of the three-way valve, so that the refrigerant passes through the first three-way valve 331 and then reaches the first connection valve 351. At this time, the first connection valve 351 is in a direct-flow state, and then it is suitable to be introduced into the first flow path 321 for heat exchange to melt the frost condensed on the first flow path 321, and is transmitted to the throttling device 400 through the third three-way valve 341. At this time, the refrigerant can also pass through the second three-way valve 332 and then reach the second connection valve 352, and then it is suitable to be introduced into the second flow path 322 for heat exchange to constitute the output performance of the heat exchanger 310. At this time, the second connection valve 352 is in a direct-flow state, and then it is transmitted to the throttling device 400 through the fourth three-way valve 342 to complete the refrigerant cycle of the air conditioner 10.

[0058] According to the air conditioner 10 of the embodiment of the present invention, during the use of the air conditioner 10, it is suitable to adjust the flow direction of the refrigerant through a plurality of three-way valves, so that the refrigerant can release heat on one of the multiple circulation flow paths 320 to constitute the output performance of the air conditioner 10, and at the same time, it can also absorb heat on another one of the multiple circulation flow paths 320 to condense frost. Then, the refrigerant is introduced into the multiple circulation flow paths 320 to release heat to melt the frost, so as to achieve the cleaning effect. At the same time, during the cleaning process, one of the multiple circulation flow paths 320 can also be used to form the output performance of the air conditioner 10, so that the air conditioner 10 can still maintain a certain output performance during the cleaning process, so that the air conditioner 10 can achieve the cleaning function without stopping, allowing the user to feel the output performance of the air conditioner 10 while realizing the cleaning, thereby improving the use experience of the air conditioner 10.
