[0002] With the improvement of people's living standards, the demand for integrated air conditioners with fresh air treatment functions is increasing. When the existing integrated air conditioner is in the fresh air mode, the condenser cannot dissipate heat quickly and timely, and the energy consumption of the integrated air conditioner is relatively high, resulting in an increase in the operating cost of the integrated air conditioner. Summary of the Invention

[0005] The integrated air conditioner according to the first aspect embodiment of the present invention includes:

[0006] A chassis, including a housing and a partition assembly disposed inside the housing.

[0042] Refer to Figures 1 to 7 and in combination with Figure 9, the integrated air conditioner according to the first aspect embodiment of the present invention includes a chassis, an air compressor 200, a first water receiving tray 310, a second water receiving tray 320, and a water spraying member 400. The chassis includes a housing 110 and a partition assembly 120 disposed inside the housing 110. The partition assembly 120 is used to divide the interior of the housing 110 into an outdoor cavity 101 and an indoor cavity 102. A cover plate 130 is provided on the side of the partition assembly 120 close to the outdoor cavity 101. The cover plate 130 and the partition assembly 120 enclose a heat exchange cavity 103. The outdoor cavity 101 has an outdoor air inlet 104 and an outdoor air outlet 105. A first heat exchanger 140 and a first fan 150 are provided in the outdoor cavity 101. The first fan 150 is used to introduce outdoor air flow from the outdoor air inlet 104. The indoor cavity 102 has an indoor air outlet 106. A second heat exchanger 160 and a second fan 170 are provided in the indoor cavity 102. The second fan 170 is used to discharge the air flow in the indoor cavity 102 from the indoor air outlet 106. The air compressor 200 is disposed in the chassis. The air compressor 200 is connected in series with the first heat exchanger 140 and the second heat exchanger 160 through pipes. The first water receiving tray 310 is disposed at the bottom of the first heat exchanger 140. The second water receiving tray 320 is disposed at the bottom of the second heat exchanger 160. The first water receiving tray 310 and the second water receiving tray 320 are connected through a connecting pipe 330. The water spraying member 400 is disposed on the top of the first heat exchanger 140. The water spraying member 400 is provided with a plurality of water spraying holes 410. The heat exchange cavity 103 is connected to the first water receiving tray 310 through a first water pipe 340. The heat exchange cavity 103 is connected to the water spraying member 400 through a second water pipe 350. A pump body 360 is provided on the first water pipe 340 or the second water pipe 350. The pump body 360 is used to pump the water in the first water receiving tray 310 onto the water spraying member 400. Thus, by providing the water spraying member 400 and the pump body 360, the pump body 360 can pump the water in the first water receiving tray 310 into the heat exchange cavity 103. The water in the heat exchange cavity 103 exchanges heat with the low-temperature air in the indoor cavity 102 through the partition assembly 120, so that the temperature of the water in the heat exchange cavity 103 is reduced. Then, the pump body 360 pumps the water in the heat exchange cavity 103 onto the water spraying member 400. The water on the water spraying member 400 is sprayed onto the first heat exchanger 140 through the water spraying holes 410, which can quickly reduce the temperature of the first heat exchanger 140, thereby reducing the energy consumption of the integrated air conditioner.

[0043] For example, when the integrated air conditioner is operating, the condensed water generated by the heat exchange between the second heat exchanger 160 and the air in the indoor cavity 102 flows into the second water receiving tray 320. The condensed water in the second water receiving tray 320 flows through the connecting pipe 330 into the first water receiving tray 310. After the integrated air conditioner has been operating for a period of time, the temperature of the first heat exchanger 140 is relatively high, and the first blower 150 cannot meet the heat dissipation requirements of the first heat exchanger 140. At this time, the pump body 360 is started. The pump body 360 can pump the water in the first water receiving tray 310 into the heat exchange cavity 103. The water in the heat exchange cavity 103 exchanges heat with the low-temperature air in the indoor cavity 102 through the partition assembly 120, so that the temperature of the water in the heat exchange cavity 103 is reduced. After that, the pump body 360 pumps the water in the heat exchange cavity 103 out onto the water spraying member 400. The water on the water spraying member 400 is sprayed onto the first heat exchanger 140 through the water spraying holes 410, which can quickly reduce the temperature of the first heat exchanger 140, thereby reducing the energy consumption of the integrated air conditioner.

[0044] It should be noted that since the first water receiving tray 310 is installed in the outdoor cavity 101 and the temperature of the outdoor cavity 101 is higher than that of the indoor cavity 102, the temperature of the water in the first water receiving tray 310 is lower than that in the second water receiving tray 320. Directly using the water in the first water receiving tray 310 to cool the first heat exchanger 140 has a poor effect. By introducing the water in the first water receiving tray 310 into the heat exchange cavity 103 through the pump body 360, the temperature of the water can be reduced to accelerate the cooling speed of the first heat exchanger 140, which will not be elaborated here.

[0045] It can be understood that in the above embodiment, the housing 110 is generally in a cuboid shape. In other embodiments of the present invention, the shape of the housing 110 can also be set to other shapes, such as cylindrical, elliptical or other shapes, rather than being limited to the above cuboid shape, which can be determined according to actual needs.

[0046] Refer to Figure 10 , in some embodiments of the present invention, the integrated air conditioner further includes a water pumping assembly. The water pumping assembly includes a water pumping impeller 510 and a driving motor 620. The water pumping impeller 510 is rotatably connected to the first water receiving tray 310. The output end of the driving motor 620 is connected to the water pumping impeller 510. The driving motor 620 can drive the water pumping impeller 510 to rotate, so that the water pumping impeller 510 can lift the water in the first water receiving tray 310. The water lifted by the water pumping impeller 510 can exchange heat with the first heat exchanger 140 to reduce the temperature of the first heat exchanger 140, thereby assisting the first heat exchanger 140 in heat dissipation and accelerating the cooling speed of the first heat exchanger 140.

[0047] It can be understood that during the actual implementation process, the temperature of the first heat exchanger 140 during operation is between 40 degrees Celsius and 60 degrees Celsius. When the water lifted by the water pumping impeller 510 comes into contact with the first heat exchanger 140, the water adhering to the first heat exchanger 140 will not evaporate. The water adhering to the first heat exchanger 140 will fall back into the first water receiving tray 310 under the action of its own gravity to be lifted again by the water pumping impeller 510. After multiple cycles, the temperature of the water in the first water receiving tray 310 gradually increases, resulting in a reduced heat dissipation effect of the water pumping assembly.

[0048] Based on this, the present invention is provided with a heat exchange chamber 103 and a pump body 360. After the water in the first water receiving tray 310 exchanges heat with the first heat exchanger 140, the pump body 360 can introduce the water in the first water receiving tray 310 into the heat exchange chamber 103, which can reduce the temperature of the water to accelerate the cooling rate of the first heat exchanger 140, thereby improving the heat dissipation effect of the water pumping assembly.

[0049] In some embodiments of the present invention, the cover plate 130 is provided with a water inlet joint and a water outlet joint 131. The water inlet joint and the water outlet joint 131 are respectively communicated with the heat exchange chamber 103. The water inlet joint is connected to the first water pipe 340, and the water outlet joint 131 is connected to the second water pipe 350. Along the up and down direction, the water inlet joint is lower than the water outlet joint 131. Thus, when the pump body 360 stops working, the water in the heat exchange chamber 103 can flow back into the first water receiving tray 310 under the action of its own gravity, and the accumulation of water in the heat exchange chamber 103 can be avoided.

[0050] It should be noted that along the axial direction of the water inlet joint, the effective cross-sectional area of the heat exchange chamber 103 is larger than the cross-sectional area of the water inlet joint. When the water enters the heat exchange chamber 103 from the water inlet joint, the flow of the water suddenly expands, which can reduce the flow rate of the water so that the water can be fully heat-exchanged in the heat exchange chamber 103, effectively reducing the temperature of the water, thereby improving the heat exchange effect of the first heat exchanger 140.

[0051] Refer to Figure 7 、 Figure 8, in some embodiments of the present invention, the partition assembly 120 includes a first main body 121, a heat insulation ring 123, and a second main body 122. The first main body 121 is connected to a part of the inner wall of the housing 110. The first main body 121 is provided with a through hole. The outer periphery of the heat insulation ring 123 is connected to the periphery of the through hole. The second main body 122 is connected to the inner periphery of the heat insulation ring 123. A first heat insulation member is provided on the side of the first main body 121 facing the indoor cavity 102. The second main body 122 and the cover plate 130 enclose a heat exchange cavity 103. A second heat exchange member is provided on the side of the cover plate 130 facing the second main body 122, which can reduce the heat exchange between the low-temperature air in the indoor cavity 102 and the high-temperature air in the outdoor cavity 101 through the first main body 121, and reduce the heat exchange between the low-temperature air in the heat exchange cavity 103 and the high-temperature air in the outdoor cavity 101 through the second main body 122, thereby...

[0052] For example, the heat insulation ring 123 is in a circular ring structure. The heat insulation ring 123 is made of heat insulation materials such as extruded polystyrene. The outer periphery of the first main body 121 is connected to a part of the inner wall of the housing 110. The second main body 122 is connected to the first main body 121 through the heat insulation ring 123. The first main body 121, the heat insulation ring 123, and the second main body 122 are spliced to form the partition assembly 120. The second main body 122 and the cover plate 130 enclose the heat exchange cavity 103. Since the through hole is not covered by the first heat insulation member, when the air conditioner integrated machine works, the low-temperature air in the indoor cavity 102 can directly exchange heat with the air in the heat exchange cavity 103 through the second main body 122, so that the heat exchange cavity 103 is in a low-temperature environment. When the water in the first water receiving tray 310 enters the heat exchange cavity 103, it is cooled, which can reduce the temperature of the water to improve the heat dissipation effect of the first heat exchanger 140.

[0053] In some embodiments of the present invention, the air conditioner integrated machine further includes a ventilation control component. The ventilation control component is arranged in the outdoor cavity 101. The outdoor cavity 101 has a fresh air outlet 107. The ventilation control component is used to open or close the fresh air outlet 107, which can introduce fresh air into the room, thereby improving the user experience.

[0054] For example, the air conditioner integrated machine has a fresh air mode and a cooling mode. When the air conditioner integrated machine is in the cooling mode, the ventilation control component closes the fresh air outlet 107. The first fan 150 introduces outdoor air from the outdoor air inlet 104, and the outdoor air passes through the first heat exchanger 140 and is discharged to the outside through the outdoor air outlet 105, which can cool the first heat exchanger 140. When the air conditioner integrated machine is in the fresh air mode, the ventilation control component opens the fresh air outlet 107. The first fan 150 introduces outdoor air from the outdoor air inlet 104. Part of the outdoor air passes through the first heat exchanger 140 and is discharged to the outside through the outdoor air outlet 105, and the other part of the outdoor air flows into the room through the fresh air outlet 107 to reduce the carbon dioxide concentration in the room, thereby improving the user experience.

[0055] In some embodiments of the present invention, the ventilation control component includes a fresh air door 610 and a first driving member 520. The fresh air door 610 is rotatably connected to the housing 110 so that the fresh air door 610 has an open state for opening the fresh air outlet 107 and a closed state for closing the fresh air outlet 107. The first driving member 520 is used to drive the fresh air door 610 to switch between the open state and the closed state, which can facilitate the switching of the air conditioner integrated machine between the fresh air mode and the refrigeration mode, thus facilitating the use of the user.

[0056] For example, when the air conditioner integrated machine is in the refrigeration mode, the first driving member 520 drives the fresh air door 610 to close the fresh air outlet 107 to prevent the air in the outdoor cavity 101 from flowing into the indoor cavity 102. When the air conditioner integrated machine switches from the refrigeration mode to the fresh air mode, the first driving member 520 drives the fresh air door 610 to rotate in a direction away from the fresh air outlet 107 so that the fresh air door 610 opens the fresh air outlet 107. Part of the outdoor air is discharged to the outside through the outdoor air outlet 105 after passing through the first heat exchanger 140, and the other part of the outdoor air flows into the room through the fresh air outlet 107 to reduce the carbon dioxide concentration in the room, thereby improving the user experience.

[0057] As another implementation manner, the fresh air door 610 can also be slidably disposed on the housing 110, which is not limited herein.

[0058] In some embodiments of the present invention, a swing rod is connected to the output end of the first driving member 520, and the other end of the swing rod is in transmission connection with the fresh air door 610. The first driving member 520 can drive the fresh air door 610 to open or close the fresh air outlet 107 through the swing rod. By adopting the above structure, the layout of the ventilation control component in this embodiment can be made more reasonable, so that the driving motor 620 can drive the fresh air door 610 to swing upward or downward relative to the housing 110 more labor-savingly.

[0059] After the air conditioner integrated machine performs refrigeration work for a period of time, the temperature of the first heat exchanger 140 becomes very high. If the driving motor 620 drives the fresh air door 610 to swing upward relative to the housing 110 to open the fresh air outlet 107 for ventilation, the fresh air inhaled from the outside by the first blower 150 is blown into the outdoor cavity 101. When the fresh air contacts the first heat exchanger 140 during the flowing process, or when the fresh air flows past the first heat exchanger 140, the first heat exchanger 140 heats up the fresh air, making the fresh air become hot air. The hot air is then transported into the room through the fresh air outlet 107, which will cause the originally lower temperature in the room to rise greatly, thus greatly changing the original temperature in the room.

[0060] To solve the above problems, in some embodiments of the present invention, the first blower 150 has a first air outlet 151, the fresh air outlet 107 is located directly below the fresh air outlet 107, the first heat exchanger 140 is provided on one side of the fresh air outlet 107, and when the fresh air door 610 is in the open state, the fresh air door 610 is located between the first heat exchanger 140 and the fresh air outlet 107. By adopting the above structure, when the air conditioner integrated machine of this embodiment opens the fresh air outlet 107 for ventilation, the fresh air inhaled by the first blower 150 from the outside is blown downward from the first air outlet 151. Since the fresh air door 610 is located between the first heat exchanger 140 and the fresh air outlet 107, at this time, the fresh air door 610 can block most of the fresh air from contacting the first heat exchanger 140, or the fresh air door 610 blocks the first heat exchanger 140 from exchanging heat with the fresh air flowing near the first heat exchanger 140. Therefore, most of the fresh air enters the room from the fresh air outlet 107 without being interfered by the first heat exchanger 140, thus greatly reducing the influence of the first heat exchanger 140 on the fresh air. When the air conditioner integrated machine of this embodiment ventilates the room, the temperature change in the room is small, greatly reducing the influence of the ventilation of the air conditioner integrated machine on the indoor temperature. Therefore, when the air conditioner integrated machine subsequently cools the room, it does not need to cool the room too much, which helps to reduce the energy consumption of the air conditioner integrated machine.

[0061] It can be understood that after the fresh air door 610 is opened for a period of time, the area of the first heat exchanger 140 blocked by the fresh air door 610 cannot be effectively cooled by the outdoor air, resulting in a relatively high temperature in the area of the first heat exchanger 140 blocked by the fresh air door 610, causing the local temperature of the first heat exchanger 140 to be too high and affecting the energy consumption of the air conditioner integrated machine. To solve the above technical problems, in some embodiments of the present invention, the fresh air door 610 includes a door body and an opening and closing member slidably provided on the door body. The output end of the first driving member 520 is connected to the door body. The door body is provided with ventilation holes, and the opening and closing member is movably provided on the fresh air door 610 to open or close the ventilation holes. Among them, when the fresh air door 610 is in the closed state, the opening and closing member closes the ventilation holes. When the fresh air door 610 is in the open state, the opening and closing member opens the ventilation holes. The ventilation holes face the first heat exchanger 140, and the part of the first heat exchanger 140 blocked by the door body. The low-temperature air in the outdoor cavity 101 can flow into the area of the first heat exchanger 140 blocked by the fresh air door 610 through the ventilation holes to reduce the temperature of the area of the first heat exchanger 140 blocked by the fresh air door 610, and can avoid the local temperature of the first heat exchanger 140 from being too high, thereby reducing the energy consumption of the air conditioner integrated machine.

[0062] In some embodiments of the present invention, the air conditioner integrated machine is provided with a linkage structure. When the fresh air door 610 is in the open state, the linkage structure drives the opening and closing member to open the ventilation holes, eliminating the need to drive the opening and closing member to slide through power components such as motors or cylinders, which can reduce the energy consumption of the air conditioner integrated machine.

[0063] For example, the linkage structure includes a first linkage member provided on the first heat exchanger 140 and a second linkage member provided on the opening and closing member. The first linkage member is provided with a first inclined surface, and the second linkage member is provided with a second inclined surface. When the fresh air door 610 is in the open state, the first inclined surface abuts against the second inclined surface to cause the opening and closing member to open the ventilation hole. There is no need to drive the opening and closing member to slide through power components such as a motor or a cylinder, which can reduce the energy consumption of the integrated air conditioner.

[0064] In some embodiments of the present invention, a reset member is provided between the opening and closing member and the fresh air door 610. When the fresh air door 610 is in the closed state, the reset member drives the opening and closing member to close the ventilation hole, so that the reset member can automatically close the ventilation hole. When the fresh air door 610 is in the closed state, the air in the outdoor cavity 101 cannot flow into the fresh air outlet 107 through the ventilation hole.

[0065] For example, the reset member is a component such as a compression spring or a rubber member that can undergo axial elastic deformation. When the fresh air door 610 is in the open state, the opening and closing member opens the ventilation hole under the action of the linkage structure. At this time, the reset member is compressed, and the reset member obtains elastic potential energy. When the fresh air door 610 is in the closed state, the linkage structure is disconnected, and the reset member drives the opening and closing member to slide to close the ventilation hole, so that the reset member can automatically close the ventilation hole. When the fresh air door 610 is in the closed state, the air in the outdoor cavity 101 cannot flow into the fresh air outlet 107 through the ventilation hole.

[0066] In some embodiments of the present invention, an independent installation cavity 108 is provided inside the housing 110, and the air compressor 200 is disposed in the installation cavity 108. On the one hand, the structure of the integrated air conditioner is more compact. On the other hand, it can reduce the heat transfer of the air compressor 200 to the outdoor cavity 101 and the indoor cavity 102, which helps to reduce the energy consumption of the integrated air conditioner.

[0067] The control method of the integrated air conditioner according to the second aspect embodiment of the present invention is used to control the integrated air conditioner according to the first aspect embodiment of the present invention. The control method of the integrated air conditioner includes the following steps:

[0068] Step 1: Determine that the integrated air conditioner is in the cooling mode;

[0069] Step 2: Obtain the temperature of the first heat exchanger 140 and the water temperature in the first water receiving tray 310;

[0070] Step 3: If the temperature of the first heat exchanger 140 is less than the first preset value, control the pump body 360 to stop working; if the temperature of the first heat exchanger 140 is greater than the first preset value and the water temperature in the first water receiving tray 310 is less than the second preset value, control the pump body 360 to operate so that the water in the first water receiving tray 310 is sprinkled on the first heat exchanger 140 through the water spraying holes 410; if the water temperature in the first water receiving tray 310 is greater than the second preset value, control the pump body 360 to stop working.

[0071] The method for determining the first preset value includes:

[0072] Obtain a first data set, which includes the refrigeration efficiency of the air conditioner integrated unit, the outdoor air temperature, the air temperature in the indoor cavity 102, the air temperature in the outdoor cavity 101, and the liquid level height in the first water receiving tray 310;

[0073] Use a first evaluation model to predict the first data set to obtain first temperature data;

[0074] Judge whether the first temperature data is greater than a first threshold. If the first temperature data is greater than the first threshold, use a second evaluation model to predict the first data set and historical detection data to obtain second temperature data;

[0075] Judge whether the second temperature data is greater than the first threshold. If the second temperature data is still greater than the first threshold, process the first data set to obtain a second data set. This processing can be adding the water temperature in the second water receiving tray 320 and the air temperature in the heat exchange cavity 103 to the first data set. Use a third evaluation model to predict the second data set and historical detection data to obtain third temperature data. The third temperature data is the temperature at which the pump body 360 operates when the air conditioner integrated unit is in the refrigeration mode;

[0076] If the second temperature data is less than the first threshold, the second temperature data is the temperature of the first heat exchanger 140 when the air conditioner integrated unit controls whether the pump body 360 operates in the refrigeration mode.

[0077] It should be noted that the first evaluation model is a binary classification model. The model structure and training method of the first evaluation model can be selected from the prior art and will not be elaborated here.

[0078] It should be noted that both the second evaluation model and the third evaluation model are multi-classification models. Each classification category in the vector predicted by the second evaluation model and the third evaluation model is the corresponding relationship between the data category and the temperature level. The model structure and training method of the second evaluation model and the third evaluation model can be selected from the prior art and will not be elaborated here.

[0079] The method for determining the second preset value includes:

[0080] Obtain a third data set, which includes the refrigeration efficiency of the integrated air conditioner, the outdoor air temperature, the air temperature in the outdoor chamber 101, the indoor air temperature, and the air temperature in the indoor chamber 102;

[0081] Use a fourth evaluation model to predict the second data set to obtain fourth temperature data;

[0082] Determine whether the fourth temperature data is greater than the second threshold. If the third temperature data is greater than the second threshold, then use a fifth evaluation model to predict the second data set and the historical detection data to obtain fifth temperature data;

[0083] Determine whether the fifth temperature data is greater than the second threshold. If the fifth temperature data is still greater than the second threshold, then process the third data set to obtain a fourth data set. This processing can be adding the cumulative working time of the integrated air conditioner and the air temperature in the heat exchange chamber 103 to the third data set. Use a sixth evaluation model to predict the fourth data set and the historical detection data to obtain sixth temperature data. The sixth temperature data is the temperature at which the pump body 360 operates when the integrated air conditioner is in the refrigeration mode;

[0084] If the fifth temperature data is less than the second threshold, then the fifth temperature data is the water temperature of the first water receiving tray 310 for controlling whether the pump body 360 operates when the integrated air conditioner is in the refrigeration mode.

[0085] It should be noted that the fourth evaluation model is a binary classification model. The model structure and training method of the fourth evaluation model can be selected from the prior art and will not be elaborated here.

[0086] It should be noted that both the fifth evaluation model and the sixth evaluation model are multi-classification models. Each classification category in the vectors predicted by the fifth evaluation model and the sixth evaluation model is the corresponding relationship between the data category and the temperature level. The model structures and training methods of the fifth evaluation model and the sixth evaluation model can be selected from the prior art and will not be elaborated here.

For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0088] The above has described this embodiment in detail with reference to the drawings, but the present invention is not limited to the above embodiment. Within the scope of knowledge possessed by those of ordinary skill in the art in the technical field, various changes can be made without departing from the gist of the present invention.
