air conditioner

Abstract

This application relates to an air conditioner with a water storage tank in its chassis. The bottom wall of the water storage tank has a flow channel and a first recess. The flow channel has a first end and a second end, both of which are connected to the first recess. The bottom of a water-applying ring extends into the water storage tank. Along the direction of condensate flow in the first recess, one of the first and second ends is arranged on one side of the water-applying part of the water-applying ring, and the other is arranged on the other side. When the fan blades and the water-applying ring rotate at high speed, compressing the condensate in the water storage tank, causing the condensate to flow from one side of the water-applying part of the water-applying ring to the other side, the condensate in the first recess will, for example, enter the flow channel through the first end, and can then flow back from the second end to one side of the water-applying part of the water-applying ring. This allows the condensate to circulate repeatedly in the first recess and the flow channel, ensuring that the liquid level in the first recess meets the water-applying requirements. This ensures that the water-applying ring is always in contact with the condensate, thereby improving the energy efficiency of the air conditioner.

Description

Technical Field

[0001] This application relates to the field of air treatment technology, and in particular to an air conditioner. Background Technology

[0002] The outdoor heat exchanger of an air conditioner is usually compatible with both cooling and heating needs. When the air conditioner is in cooling mode, the outdoor heat exchanger acts as a condenser to condense and release heat from the high-temperature, high-pressure refrigerant flowing through it. When the air conditioner is in heating mode, the outdoor heat exchanger acts as an evaporator to evaporate and absorb heat from the low-temperature, low-pressure refrigerant flowing through it.

[0003] When the outdoor heat exchanger acts as a condenser, the outlet refrigerant temperature of the outdoor heat exchanger will affect the coefficient of performance (COP) of the air conditioner. In order to improve the COP of the air conditioner, related technologies not only use an outdoor fan to dissipate heat from the outdoor heat exchanger, but also use the rotation of the outdoor fan to drive some of the condensate (forming water mist or droplets) to be distributed on the condenser surface to enhance heat dissipation.

[0004] However, when the fan is running, the condensate may not be able to be pumped up, the condenser cannot be cooled down properly, and the temperature is too high, which leads to a decrease in the energy efficiency of the air conditioner. Utility Model Content

[0005] Therefore, it is necessary to provide an air conditioner that addresses the shortcomings of existing technologies by ensuring that more condensate in the water storage tank is pumped up, thereby improving energy efficiency.

[0006] This application provides an air conditioner, including:

[0007] The refrigerant circulation loop includes a compressor, a condenser, a first throttling device, and an evaporator. The condenser and the evaporator are both connected to the compressor. The first throttling device is connected between the condenser and the evaporator. One of the condenser and the evaporator is an outdoor heat exchanger, and the other is an indoor heat exchanger.

[0008] Housing, the housing comprising:

[0009] The chassis includes a water storage tank located below the outdoor heat exchanger. The bottom wall of the water storage tank has a flow channel and a first recess recessed area facing away from the outdoor heat exchanger. The flow channel has a first end and a second end opposite to each other, both of which communicate with the first recess recess.

[0010] The main housing is connected to the chassis and cooperates to form a receiving space, and the refrigerant circulation loop is arranged within the receiving space;

[0011] An outdoor fan is located within the accommodating space, and is positioned correspondingly to the water storage tank. The outdoor fan drives outdoor air through the outdoor heat exchanger to facilitate heat exchange between the refrigerant and the outdoor air. The outdoor fan includes:

[0012] Drive motor;

[0013] Fan blades, the drive motor is connected to the fan blades, and the drive motor is used to drive the fan blades to rotate; and

[0014] A water-spraying ring is arranged circumferentially around the fan blades, with its bottom extending into the water storage tank. The projection of the water-spraying ring along the direction perpendicular to the bottom wall of the water storage tank at least partially overlaps with the first recess. Along the direction of condensate flow in the first recess, one of the first end and the second end is arranged on one side of the water-spraying part of the water-spraying ring, and the other end is arranged on the other side of the water-spraying part of the water-spraying ring.

[0015] In one embodiment, the bottom wall of the first recess is lower than the bottom wall of the flow channel.

[0016] In one embodiment, the bottom wall of the first recess has a second recess that is recessed away from the outdoor heat exchanger, and the projection of the water jet ring along the bottom wall perpendicular to the water storage tank at least partially overlaps with the second recess.

[0017] In one embodiment, the bottom wall of the first recess is provided with a support portion protruding toward the outdoor heat exchanger, the support portion abutting against the bottom surface of the outdoor heat exchanger, so that a water flow gap is formed between the bottom surface of the outdoor heat exchanger and the bottom wall of the first recess.

[0018] In one embodiment, the support portion is provided as a rib, which extends parallel to the condensate flow direction within the first recess; and the number of ribs is at least two and arranged sequentially along the air outlet direction of the outdoor fan.

[0019] In one embodiment, the air conditioner further includes an outdoor air duct component; the outdoor air duct component is disposed within the accommodating space, the outdoor air duct component is disposed between the outdoor heat exchanger and the outdoor fan, and the outdoor air duct component is used to guide the air blown out by the outdoor fan to the outdoor heat exchanger.

[0020] In one embodiment, the outdoor duct component includes a reflector located on the water outlet side of the water-spraying ring. The reflector has a reflective surface, which is set at an angle to the rotation axis of the water-spraying ring. Along the air outlet direction of the outdoor fan, the distance between the rotation axis of the water-spraying ring and the reflective surface increases.

[0021] In one embodiment, the air conditioner further includes:

[0022] A water collector is located at the top of the outdoor air duct component, on the outlet side of the water-spraying ring, and can collect the condensate water agitated by the water-spraying ring. The bottom of the water collector is in contact with the outdoor heat exchanger and / or located above the outdoor heat exchanger.

[0023] In one embodiment, the top wall of the outdoor air duct component is provided with a guide member. Along the front-rear direction of the air conditioner, the distance between the guide member and the bottom wall of the water storage tank decreases. The bottom end of the guide member abuts against the outdoor heat exchanger and / or is located above the outdoor heat exchanger.

[0024] In one embodiment, the air conditioner further includes:

[0025] A collection tray is provided inside the chassis and located below the indoor heat exchanger. The collection tray is used to collect condensate generated by the indoor heat exchanger. The collection tray is provided with a discharge section for discharging the condensate in the collection tray into the water storage tank.

[0026] In the aforementioned air conditioner, a flow channel is provided in the water storage tank. The first and second ends of the flow channel are both connected to the first recess. Along the direction of condensate flow in the first recess, one of the first and second ends is arranged on one side of the water-applying part of the water-applying ring, and the other is arranged on the other side. In this way, when the fan blades and the water-applying ring rotate at high speed, they compress the condensate in the water storage tank, causing the condensate to flow from one side of the water-applying part of the water-applying ring to the other side. The condensate in the first recess will, for example, enter the flow channel through the first end, and can then flow back from the second end to one side of the water-applying part of the water-applying ring. This allows the condensate to circulate repeatedly in the first recess and the flow channel, ensuring that the liquid level in the first recess meets the water-applying requirements. This avoids the defect that the condensate is compressed to the other side of the water-applying part and cannot flow back in time, resulting in a low condensate level at the water-applying part and causing water-applying failure. This ensures that the water-applying ring can always contact the condensate, thereby ensuring that the condensate in the water storage tank is agitated, thus improving the energy efficiency of the air conditioner.

Detailed Implementation

[0049] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0050] It should be noted that, for ease of description and understanding, the terms "front," "rear," "up," "down," "left," and "right" in this embodiment refer to the installation state of the air conditioner during normal use. The direction from which the air outlet of the indoor heat exchanger faces the user is considered "front," and the direction away from the user is considered "rear." The vertical direction is the up-down direction, and the direction perpendicular to both the front-back and vertical directions is the left-right direction. For example... Figures 1 to 3 As shown.

[0051] This embodiment provides an air conditioner, which includes a refrigeration system for exchanging heat with indoor and outdoor air to meet cooling or heating needs.

[0052] The refrigeration system includes a compressor, a condenser, a first throttling device, and an evaporator. In this application, the air conditioner performs the refrigeration cycle by using the compressor, condenser, first throttling device, and evaporator.

[0053] The compressor compresses refrigerant gas at a low temperature and low pressure and discharges the compressed, high-temperature, high-pressure 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.

[0054] The first throttling device is, for example, an expansion valve, which causes the high-temperature, high-pressure liquid refrigerant condensed in the condenser to expand into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant that has expanded in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor.

[0055] An evaporator achieves a cooling effect by exchanging heat with the material being cooled using the latent heat of refrigerant evaporation. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0056] The outdoor unit of an air conditioner refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. The indoor unit of an air conditioner includes the indoor heat exchanger, and an expansion valve can be provided in either the indoor or outdoor unit.

[0057] The indoor and outdoor heat exchangers function as either condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner functions as a heater in heating mode; when the indoor heat exchanger is used as an evaporator, the air conditioner functions as a cooler in cooling mode.

[0058] An air conditioner consists of an indoor unit and an outdoor unit, which can be configured as an integrated unit or a split unit.

[0059] The air conditioner includes, but is not limited to, integrated units and split units. An integrated unit refers to an air conditioner where the outdoor and indoor units are integrated into one unit. A split unit refers to an air conditioner where the outdoor and indoor units are separate units. For example, the air conditioner in this embodiment will be described using an integrated unit as a specific example.

[0060] The complete unit can be, for example, a window unit, a portable unit, a rooftop unit, or a kitchen air conditioner.

[0061] The refrigerant circulation loop in this application allows the refrigerant to circulate within a circuit consisting of a compressor, condenser, electronic expansion valve, and evaporator. One of the condensers and evaporator is an outdoor heat exchanger, and the other is an indoor heat exchanger. The indoor heat exchanger exchanges heat with the air inside the indoor unit, and the outdoor heat exchanger exchanges heat with the air inside the outdoor unit, thereby fulfilling the cooling or heating requirements of the air conditioner.

[0062] The indoor unit also includes an indoor fan, which is located near the return air vent or air outlet of the indoor heat exchanger. It is used to deliver the heat-exchanged air into the room. The indoor fan has multiple speed settings to change the airflow speed at the air outlet.

[0063] An air guide plate is installed at the air outlet. By changing its relative rotation angle with the air outlet, the air guide plate adjusts the direction of the airflow through the air outlet, thereby affecting the stratification of indoor air temperature.

[0064] The outdoor unit also includes an outdoor fan, which is located on one side of the outdoor heat exchanger so that outdoor air can be delivered to the outdoor heat exchanger for heat exchange.

[0065] In the embodiments shown in this application, the air conditioner also includes a controller, which is a device that can generate operation control signals according to instruction operation codes and timing signals to instruct the air conditioner to execute control commands. For example, in response to a power-on or power-off command issued by a user, the controller can perform an operation related to the object selected by the power-on or power-off command.

[0066] As described in the background section, in the prior art, the condensate cannot be agitated when the fan is working, resulting in the condenser not being cooled effectively and the temperature being too high, thus reducing the energy efficiency of the air conditioner. The reason for this problem is that when the amount of water in the water tank is small, or when the fan speed increases and the air pressure reaches a certain value, causing the water in the water tank to be blown to other parts of the chassis, the bottom of the water agitator is located above the liquid surface in the water tank and at a certain distance from it. This prevents the water agitator from agitating the condensate in the water tank when the fan is rotating, causing the fan to lose its water agitation function.

[0067] Based on the above reasons, this application provides an air conditioner that can ensure that more condensate in the water storage tank is pumped up, thereby improving energy efficiency.

[0068] The following is for reference. Figures 1-20 This application describes an air conditioner according to an embodiment of the present application.

[0069] Please see Figure 20 One embodiment of this application provides an air conditioner including a refrigerant circulation loop. The refrigerant circulation loop includes a compressor 10, a condenser, a first throttling device 30, and an evaporator. Both the condenser and the evaporator are connected to the compressor 10. The first throttling device 30 is connected between the condenser and the evaporator. One of the condenser and the evaporator is an outdoor heat exchanger 20, and the other is an indoor heat exchanger 40.

[0070] Please see Figure 1 and Figure 3 For example, the air conditioner also includes a housing 80. For example, the housing 80 includes a chassis 81 and a main housing 82. The main housing 82 is connected to and cooperates with the chassis 81 to form a receiving space, and a refrigerant circulation loop is disposed within the receiving space.

[0071] Please see Figures 6 to 8 The chassis 81 is equipped with a water storage tank 811, which can be used to store condensate.

[0072] Please see Figure 3 , Figures 9 to 12 The water storage tank 811 is located below the outdoor heat exchanger 20. The bottom wall of the water storage tank 811 is provided with a flow channel 8111 and a first recess 8112 recessed away from the outdoor heat exchanger 20. The flow channel 8111 has a first end 81111 and a second end 81112 facing each other. Both the first end 81111 and the second end 81112 are connected to the first recess 8112. In this way, the flow channel 8111 and the first recess 8112 can cooperate to form a closed annular channel, which can be circulated back and forth in the annular channel under the drive of the water pumping ring 73.

[0073] Please see Figures 9 to 12 For example, the air conditioner also includes an outdoor fan 70. The outdoor fan 70 is located within the accommodating space, and its position corresponds to that of the water storage tank 811. Specifically, the projection of the outdoor fan 70 along the direction perpendicular to the bottom wall of the water storage tank 811 at least partially overlaps with the water storage tank 811, and for example, completely overlaps. The outdoor fan 70 is used to drive outdoor air through the outdoor heat exchanger 20, so that the refrigerant exchanges heat with the outdoor air.

[0074] For example, the outdoor fan 70 includes a drive motor 72, fan blades 71, and a water jet ring 73. The drive motor 72 is connected to the fan blades 71 and is used to drive the fan blades 71 to rotate.

[0075] Please see Figures 12 to 14 Specifically, the outdoor fan 70 also includes a support base 74, which is connected to the chassis 81 and is also connected to the drive motor 72, thus providing stable support for the drive motor 72.

[0076] Please see Figures 9 to 12 The water-applying ring 73 is, for example, an annular structure, and is arranged circumferentially around the fan blade 71. The bottom of the water-applying ring 73 extends into the water storage tank 811, and the projection of the water-applying ring 73 along the direction perpendicular to the bottom wall of the water storage tank 811 at least partially overlaps with the first recess 8112. Along the flow direction of condensate water in the first recess 8112, one of the first end 81111 and the second end 81112 is arranged on one side of the water-applying part of the water-applying ring 73, and the other is arranged on the other side of the water-applying part of the water-applying ring 73. The flow direction of condensate water in the first recess 8112 is from the return water side of the water-applying ring 73 to the outlet water side of the water-applying ring 73.

[0077] It should be noted that the bottom wall of the water storage tank 811 is provided with a flow channel 8111 and a first recess 8112 recessed away from the outdoor heat exchanger 20. This can also be understood as the bottom wall of the water storage tank 811 being recessed downwards to form the flow channel 8111 and the first recess 8112. That is, taking the normal installation and use of the air conditioner as a reference, the part of the bottom wall of the water storage tank 811 that is not recessed downwards is higher than the bottom wall of the flow channel 8111 and higher than the bottom wall of the first recess 8112. The part of the bottom wall of the water storage tank 811 that is not recessed downwards can also be understood as the highest point of the bottom wall of the water storage tank 811.

[0078] It should be noted that the water-spraying part of the water-spraying ring 73 refers to the part of the water-spraying ring 73 that can make the condensed water in the water storage tank 811 rise upwards, that is, the part of the water-spraying ring 73 that contacts the condensed water in the water storage tank 811, specifically the bottom of the water-spraying ring 73.

[0079] In the aforementioned air conditioner, a flow channel 8111 is provided within the water storage tank 811. Both the first end 81111 and the second end 81112 of the flow channel 8111 are connected to the first recess 8112. Along the flow direction of the condensate water within the first recess 8112, one of the first end 81111 and the second end 81112 is positioned on one side of the water-applying part of the water-applying ring 73, and the other is positioned on the other side. Thus, when the fan blades 71 and the water-applying ring 73 rotate at high speed, compressing the condensate water in the water storage tank 811, causing the condensate water to flow from one side of the water-applying part of the water-applying ring 73 to the other side, the first recess 8112… The condensate inside will enter the flow channel 8111 through the first end 81111, and can also flow back from the second end 81112 to one side of the water-spraying part of the water-spraying ring 73. This allows the condensate to circulate repeatedly in the first recess 8112 and the flow channel 8111, ensuring that the liquid level in the first recess 8112 meets the water-spraying requirements. This avoids the defect that the condensate is forced to the other side of the water-spraying part and cannot flow back in time, resulting in the condensate liquid level at the water-spraying part being too low and causing the water-spraying to fail. This ensures that the water-spraying ring 73 can always contact the condensate, thereby ensuring that the condensate in the water storage tank 811 is sprayed up, which improves the energy efficiency of the air conditioner.

[0080] Please see Figure 8 and Figure 12 For example, the bottom wall of the first recess 8112 is lower than the bottom wall of the flow channel 8111. Thus, because the bottom wall of the first recess 8112 is lower than the bottom wall of the flow channel 8111, the condensate in the water storage tank 811 is more concentrated in the first recess 8112. This ensures that the water-discharging ring 73 remains in contact with the condensate during rotation, thereby discharging the condensate in the water storage tank 811 and improving the energy efficiency of the air conditioner.

[0081] It should be noted that the phrase "lower than" in the context of the bottom wall of the first recess 8112 being lower than the bottom wall of the flow channel 8111 means that the air conditioner is installed and in use under normal conditions. For example, if the bottom wall of the water tank 811 is not recessed downwards as a reference, the distance between the bottom wall of the first recess 8112 and the bottom wall of the water tank 811 not recessed downwards is greater than the distance between the bottom wall of the flow channel 8111 and the bottom wall of the water tank 811 not recessed downwards.

[0082] The bottom walls of the flow channel 8111 and the first recess 8112 are both lower than the height of the non-recessed portion of the bottom wall of the water storage tank 811. The non-recessed portion of the bottom wall of the water storage tank 811 is located between the flow channel 8111 and the first recess 8112, and is a convex bulge 8114 that protrudes upwards relative to the flow channel 8111 and the first recess 8112. The convex bulge 8114 allows condensate in the water storage tank 811 to collect within the water storage tank 8111 and the flow channel 8111.

[0083] Please see Figures 9 to 12 For example, the bottom wall of the first recess 8112 is provided with a second recess 8113 recessed away from the outdoor heat exchanger 20, and the projection of the water-discharging ring 73 along the bottom wall perpendicular to the water storage tank 811 at least partially overlaps with the second recess 8113. Thus, when there is little condensate in the water storage tank 811 or the rotation speed of the water-discharging ring 73 is too low to blow up the condensate in the second recess 8113, the condensate in the first recess 8112 can collect in the second recess 8113, and the condensate does not stagnate in the flow channel 8111 or other locations. Furthermore, since the projection of the water-discharging ring 73 along the bottom wall perpendicular to the water storage tank 811 at least partially overlaps with the second recess 8113, the effect of the water-discharging ring 73 on the condensate during rotation is relatively significant. This ensures that the ring remains in contact with the condensate during rotation, facilitating the blowing up of the condensate in the water storage tank 811, thereby improving the energy efficiency of the air conditioner. Furthermore, under the backflow effect of the flow channel 8111, the condensate blown away by the high-speed rotating water-blowing ring 73 can flow back into the second recess 8113 in a timely manner, thereby improving the water-blowing capacity of the outdoor fan 70 and making full use of the condensate.

[0084] It should be noted that the bottom wall of the first recess 8112 is provided with a second recess 8113. This can also be understood as a partial downward recess of the bottom wall of the first recess 8112 to form the second recess 8113. In other words, with reference to the normal installation and use of the air conditioner, the portion of the bottom wall of the first recess 8112 that is not downward recessed is higher than the bottom wall of the second recess 8113.

[0085] It should be noted that in this embodiment, the bottom of the water-spraying ring 73 can either extend into the second recess 8113 or not. As long as it extends into the water storage tank 811, effective water spraying can be achieved.

[0086] Specifically, when the bottom of the water-spraying ring 73 extends into the second recess 8113, it can also be understood that the bottom of the water-spraying ring 73 is lower than the part of the bottom wall of the first recess 8112 that is not recessed downwards. The bottom of the water-spraying ring 73 is also the part of the water-spraying ring 73 with the smallest distance from the bottom wall of the second recess 8113. Thus, since condensate collects in the second recess 8113, the bottom of the water-spraying ring 73, extending into the second recess 8113, can maintain contact with the condensate collected in the second recess 8113, thereby continuously agitating the condensate within the second recess 8113.

[0087] When the bottom of the water-spraying ring 73 does not need to extend into the second recess 8113, for example, when the bottom of the water-spraying ring 73 is located above the first recess 8112 and the second recess 8113, and specifically, for example, flush with the part of the bottom wall of the water storage tank 811 that is not recessed downwards, the water-spraying ring 73 can still lift the condensate in the water storage tank 811 when it is working.

[0088] The outdoor heat exchanger 20 is located on the air outlet side of the outdoor fan 70.

[0089] Please see Figure 3 , Figure 8 , Figure 14 and Figure 15 For example, the bottom wall of the first recess 8112 is provided with a support portion 81121 protruding towards the outdoor heat exchanger 20. The support portion 81121 abuts against the bottom surface of the outdoor heat exchanger 20, so that a water flow gap is formed between the bottom surface of the outdoor heat exchanger 20 and the bottom wall of the first recess 8112. In this way, on the one hand, the support portion 81121 can support the outdoor heat exchanger 20, so that the outdoor heat exchanger 20 is stably installed in the receiving space; on the other hand, the support portion 81121 can prevent the bottom surface of the outdoor heat exchanger 20 from being completely in contact with the bottom wall of the first recess 8112, that is, it can make the bottom surface of the outdoor heat exchanger 20 and the bottom wall of the first recess 8112 cooperate to form a water flow gap. This water flow gap allows the condensate to circulate repeatedly in the first recess 8112 and the flow channel 8111, which in turn helps the water-applying ring 73 to always contact the condensate in the water storage tank 811, ensuring the water-applying effect of the condensate.

[0090] For example, the support portion 81121 may be in various structural forms such as protrusions or ribs, and the number of support portions 81121 may be one, two, three or other, as long as it can support the outdoor heat exchanger 20 so that the bottom surface of the outdoor heat exchanger 20 and the bottom wall of the first recess 8112 form a water flow gap.

[0091] For example, the support portion 81121 is configured as a rib, which extends parallel to the condensate flow direction within the first recess 8112; and the number of ribs is at least two, arranged sequentially along the air outlet direction of the outdoor fan 70. In this way, on the one hand, the outdoor heat exchanger 20 can be stably supported; on the other hand, the arrangement of the support portion 81121 minimizes the obstruction to the flow of condensate, allowing the condensate to flow within the interval between two adjacent ribs, thus achieving normal circulation of condensate.

[0092] It should be noted that the “support part 81121” in this embodiment can be a part of the “chassis 81”, that is, the “support part 81121” and the “other parts of the chassis 81” are integrally formed; or it can be an independent component that can be separated from the “other parts of the chassis 81”, that is, the “support part 81121” can be manufactured independently and then combined with the “other parts of the chassis 81” to form a whole.

[0093] Please see Figures 13 to 15For example, the air conditioner also includes an outdoor air duct component 91. The outdoor air duct component 91 is disposed within the receiving space, between the outdoor heat exchanger 20 and the outdoor fan 70. The outdoor air duct component 91 is used to guide the air blown by the outdoor fan 70 to the outdoor heat exchanger 20. In this way, the outdoor air duct component 91 can limit the flow direction and path of the air within it, ensuring that the air blown by the outdoor fan 70 is directed to the outdoor heat exchanger 20, improving the cooling effect of the outdoor heat exchanger 20, thereby guaranteeing the cooling effect.

[0094] Specifically, the outdoor fan 70 may be entirely housed within the outdoor duct 91, providing power to the airflow within the outdoor duct 91. Alternatively, only the fan blades 71 and the water jet ring 73 may extend into the outdoor duct 91, while the drive motor 72 may be located outside the outdoor duct 91.

[0095] Specifically, the outdoor heat exchanger 20 can be entirely housed within the outdoor air duct component 91, and its outer peripheral surface abuts against, for example, the inner wall of the outdoor air duct component 91 on the air outlet side. The outer peripheral surface of the outdoor heat exchanger 20 refers to the wall surface surrounding its central axis. In this way, the outdoor heat exchanger 20 seals off the air outlet side of the outdoor air duct component 91, preventing air leakage, and allowing more air from the outlet side of the outdoor air duct component 91 to be directed towards the outdoor heat exchanger 20, thereby improving the cooling effect of the outdoor heat exchanger 20.

[0096] Of course, the outdoor heat exchanger 20 can also be arranged outside the outdoor air duct component 91, and the side of the outdoor heat exchanger 20 facing the outdoor air duct component 91 can be in contact with the air outlet side of the outdoor air duct component 91. In this way, the outdoor heat exchanger 20 seals the air outlet side of the outdoor air duct component 91 to prevent air leakage, and more air from the air outlet side of the outdoor air duct component 91 blows towards the outdoor heat exchanger 20, which is beneficial to the cooling effect of the outdoor heat exchanger 20.

[0097] To further improve the utilization rate of condensate, the outdoor air duct component 91 not only serves as a guide for airflow but also houses the condensate pumping ring 73. This ring reflects and / or guides the condensate pumping water, directing it to the outdoor heat exchanger 20. The reflected and / or guided condensate then fully contacts and exchanges heat with the outdoor heat exchanger 20, effectively reducing its temperature and thus improving its heat exchange efficiency. Therefore, by fully utilizing the condensate in the water storage tank 811, the air conditioner's energy efficiency is improved, effectively saving energy.

[0098] Please see Figure 14 and Figure 15For example, the outdoor duct component 91 includes a reflector 911. The reflector 911 is located on the water outlet side of the water-spraying ring 73, which is the side of the water-spraying ring 73 that agitates the condensate. Specifically, for example... Figure 15 The left side of the air conditioner is shown. Correspondingly, the return water side of the water ring 73 refers to the other side, specifically, for example... Figure 15 The air conditioner shown is located on the right side. The reflector 911 has a reflective surface 9111, which is angled to the rotation axis of the water-discharging ring 73. Along the air outlet direction of the outdoor fan 70, the distance between the rotation axis of the water-discharging ring 73 and the reflective surface 9111 increases. With this configuration, the reflective surface 9111 faces the condensate agitated by the water-discharging ring 73. The reflection from the reflective surface 9111 directs the condensate towards the outdoor heat exchanger 20, effectively reducing its temperature and improving its heat exchange efficiency.

[0099] Optionally, the reflector 911 may include, but is not limited to, a water deflector or a water block. In this embodiment, the reflector 911 is specifically configured as a water deflector, which is thinner and reduces material costs.

[0100] Specifically, in this embodiment, the water-spraying ring 73 and the reflector 911 are arranged, for example, along the left-right direction of the air conditioner. That is, the reflector 911 can be located either to the left or right of the water-spraying ring 73, depending on the rotation direction of the water-spraying ring 73. For example, observing the rotation direction of the water-spraying ring 73 from the rear-to-front direction of the air conditioner, when the water-spraying ring 73 rotates counterclockwise, the sprayed condensate water flies out along the tangent of the water-spraying ring 73 and moves towards the upper left under the action of inertia. The reflector 911 is correspondingly located on the left side of the water-spraying ring 73, with the reflective surface 9111 facing the condensate water sprayed by the water-spraying ring 73. The reflective surface 9111 and the rotation axis of the water-spraying ring 73 are set at an angle, and along the air outlet direction of the outdoor fan 70, the distance between the rotation axis of the water-spraying ring 73 and the reflective surface 9111 tends to increase. Thus, the reflective surface 9111 can reflect the condensate towards the outdoor heat exchanger 20, and under the action of the reflective surface 9111, the condensate is sprayed towards the outdoor heat exchanger 20, thereby effectively reducing the temperature of the outdoor heat exchanger 20 and improving its heat exchange efficiency. Conversely, the principle is similar. When the water-discharging ring 73 rotates clockwise, the condensate that is discharging flies out along the tangent of the water-discharging ring 73 and moves towards the upper right under the action of inertia. The reflective element 911 is correspondingly located on the right side of the water-discharging ring 73, and the reflective surface 9111 faces the condensate that is discharging from the water-discharging ring 73. The reflective surface 9111 and the rotation axis of the water-discharging ring 73 are set at an angle, and along the air outlet direction of the outdoor fan 70, the distance between the rotation axis of the water-discharging ring 73 and the reflective surface 9111 tends to increase. Similarly, it can reflect the condensate water towards the outdoor heat exchanger 20, thereby effectively reducing the temperature of the outdoor heat exchanger 20 and improving its heat exchange efficiency.

[0101] For example, the reflective surface 9111 can be designed as a flat surface. This flat surface allows condensate to be reflected and sprayed onto the outdoor heat exchanger 20. The angle between the flat surface and the rotation axis of the water-reflecting ring 73 can be, but is not limited to, 15° to 85°, specifically, 15°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, or 85°, etc. In this embodiment, the angle between the flat surface and the rotation axis of the water-reflecting ring 73 is, for example, selected as 30° to 60°. This ensures that most of the condensate is reflected and sprayed onto the outdoor heat exchanger 20, thereby improving the cooling effect of the outdoor heat exchanger 20. Furthermore, when the angle between the flat surface and the rotation axis of the water-reflecting ring 73 is greater than 60° or less than 30°, it will result in less condensate being reflected onto the outdoor heat exchanger 20.

[0102] For example, the reflective surface 9111 can also be an arc-shaped surface, with the center of the arc located on the side opposite to the outdoor heat exchanger 20, meaning the reflective surface 9111 protrudes towards the outdoor heat exchanger 20. In this way, the arc-shaped surface can also reflect condensate water and spray it towards the outdoor heat exchanger 20. It should be noted that, in addition to the flat or arc-shaped surface in the above embodiments, the reflective surface 9111 can also be set to other regular or irregular shapes. The specific shape can be flexibly adjusted and set according to actual needs, as long as it can reflect and spray the condensate water onto the outdoor heat exchanger 20; no limitation is imposed here.

[0103] Please see Figures 13 to 15 For example, the bottom end of the reflector 911 abuts against the bottom wall of the water storage tank 811. This abutting mechanism between the bottom end of the reflector 911 and the bottom wall of the water storage tank 811 achieves a sealed fit, thus providing better airflow guidance. Furthermore, the lower position of the bottom end of the reflector 911 results in a larger area for reflecting condensate, thereby improving the condensate reflection effect. In addition, a water flow gap is provided between the bottom end of the reflector 911 and the bottom wall of the first recess 8112, thus preventing obstruction of the backflow of condensate within the first recess 8112.

[0104] For example, the distance between the top of the reflector 911 and the bottom wall of the water storage tank 811 is H1, and the distance between the central axis of the water-spraying ring 73 and the bottom wall of the water storage tank 811 is H2, where H1 / H2 ≥ 1. Specifically, H1 / H2 can be, for example, 1, 1.1, 1.2, 1.3, 1.5, 1.8, or 2.0, etc., and can be flexibly adjusted and set according to actual needs, without limitation here. However, if the distance H1 between the top of the reflector 911 and the bottom wall of the water storage tank 811 is relatively small (H1 / H2 < 1), the area for reflecting condensate water is too small; while when H1 / H2 ≥ 1, the distance H1 between the top of the reflector 911 and the bottom wall of the water storage tank 811 is relatively large, thereby increasing the area for reflecting condensate water, which is beneficial to improving the reflection effect of condensate water.

[0105] For example, the outdoor fan 70 also includes an air guide shell 75. The air guide shell 75 has an annular structure and is arranged circumferentially around the fan blades 71, which facilitates directing the airflow from the fan blades 71 towards the outdoor heat exchanger 20. The air guide shell 75 is connected to, for example, a support base 74 and supported by the support base 74. The air guide shell 75 and the support base 74 are connected by connecting arms. The air guide shell 75 is also connected to the outdoor air duct component 91. Outdoor air, under the suction of the outdoor fan 70, enters the air guide shell 75 through the gap between two adjacent connecting arms and is blown towards the outdoor heat exchanger 20 under the guidance of the air guide shell 75 and the outdoor air duct component 91. A water-applying ring 73 extends to the outside of the air guide shell 75 to facilitate insertion into the water storage tank 811. That is, the water-applying ring 73 is closer to the outdoor heat exchanger 20 than the air guide shell 75.

[0106] Based on the aforementioned embodiments, one end of the reflector 911 closest to the outdoor fan 70 (i.e., the front end of the reflector 911) is connected to the air guide shell 75, for example, and the other end of the reflector 911 (i.e., the rear end of the reflector 911) abuts against the outdoor heat exchanger 20, for example. Thus, the reflector 911 has a large span along the front-to-back direction of the air conditioner, thereby having a large area to reflect condensate, which helps to improve the condensate reflection effect.

[0107] Please see Figure 14 and Figure 17 For example, the air conditioner also includes a water collector 60. The water collector 60 is located at the top of the outdoor air duct component 91, on the outlet side of the water-flushing ring 73. The water collector 60 can collect the condensate agitated by the water-flushing ring 73, and its bottom is in contact with and / or above the outdoor heat exchanger 20. In this way, the water collector 60 can collect the condensate agitated by the water-flushing ring 73 and guide the collected condensate to the outdoor heat exchanger 20, greatly improving the cooling capacity of the outdoor heat exchanger 20 and enhancing the energy efficiency of the air conditioner.

[0108] Please see Figure 20 For example, the water collector 60 is inclined to facilitate the downward flow of condensate under its own weight, ensuring smooth water flow. Furthermore, the bottom of the water collector 60 abuts against the outdoor heat exchanger 20, or it can be located above the outdoor heat exchanger 20. In this way, the condensate from the water collector 60 will smoothly fall into the outdoor heat exchanger 20 under its own weight.

[0109] It should be noted that the bottom of the water collector 60 refers to the relatively low part of the water collector 60 with reference to the normal installation and use of the air conditioner. For example, it can be the bottom surface of the water collector 60, or the lower part of the bottom surface and side of the water collector 60.

[0110] Specifically, in this embodiment, the bottom of the water collector 60 abuts against the top of the outdoor heat exchanger 20, meaning the water collector 60 is located at the top of the outdoor heat exchanger 20. This allows the condensate from the water collector 60 to flow to the top of the outdoor heat exchanger 20 and down along its top, resulting in more thorough cooling of the outdoor heat exchanger 20. Consequently, the outlet refrigerant temperature of the outdoor heat exchanger 20 decreases, improving its heat exchange efficiency.

[0111] Of course, as some alternative solutions, in this embodiment, the bottom of the water collector 60 can also abut against the middle part or other parts of the outdoor heat exchanger 20. This application does not impose too many restrictions here, as long as the condensate of the water collector 60 flows to the outdoor heat exchanger 20.

[0112] It should be noted that the tilt setting of the water collector 60 is based on the normal installation and use state of the air conditioner, and is tilted relative to the horizontal plane. In this embodiment, when the air conditioner is in normal installation and use state, the bottom surface of the chassis 81 is parallel to the horizontal plane, therefore, the water collector 60 is tilted relative to the bottom surface of the chassis 81.

[0113] For example, the tilt angle α of the water collector 60 relative to the horizontal plane is, but is not limited to, 1° to 45°, specifically, 5° to 30°. In this way, on the one hand, a larger tilt angle allows the condensate to flow more smoothly to the outdoor heat exchanger 20 under the action of gravity; on the other hand, the tilt angle is not so large that it occupies too much height space of the air conditioner, and it can ensure that the water pumping ring 73 pumps more condensate to the water collector 60.

[0114] After the water-discharging ring 73 rotates and pumps the condensate to the water collector 60, in order to improve the utilization rate of the condensate, the water collector 60 has the ability to absorb more than 90% or even all of the condensate pumped onto its surface, thus avoiding waste of the condensate pumped up by the water-discharging ring 73. In other words, the water collector 60 in this embodiment has water absorption characteristics.

[0115] For example, the surface of the water collector 60 is designed to be hydrophilic, effectively absorbing the condensate pumped up by the water pumping ring 73, thus improving the utilization rate of the condensate. Simultaneously, since the condensate does not easily fall downwards, it also possesses water storage characteristics. Furthermore, when the amount of condensate on the surface of the water collector 60 is large, the condensate flows downwards along the surface of the water collector 60 under its own gravity, thus possessing the characteristics of flowing water. In summary, the water collector 60, satisfying the characteristics of water absorption, storage, and flow, can effectively guide the condensate to the outdoor heat exchanger 20, resulting in a better heat exchange effect.

[0116] Please see Figures 18 to 20For example, a water collector 60 is disposed between the outdoor heat exchanger 20 and the first throttling device 30. The water collector 60 includes heat exchange fins 65 and heat exchange tubes 61. The heat exchange tubes 61 are disposed through the heat exchange fins 65. The inlet of the heat exchange tubes 61 is connected to the outlet of the outdoor heat exchanger 20, and the outlet of the heat exchange tubes 61 is connected to the inlet of the first throttling device 30. Thus, when the air conditioner is turned on for cooling, the compressed refrigerant condenses into a liquid phase in the outdoor heat exchanger 20, and the heat is released to the surrounding environment through the condensation process. The outdoor fan 70 drives outdoor air through the outdoor heat exchanger 20, allowing the refrigerant to exchange heat with the outdoor air and reducing the temperature of the outdoor heat exchanger 20. The refrigerant discharged from the outdoor heat exchanger 20 enters the heat exchange tubes 61 of the water collector 60. The water collector 60 effectively reduces the temperature of the heat exchange tubes 61 through its own accumulated condensate, and the temperature of the refrigerant is also effectively reduced through the heat exchange tubes 61. The cooled refrigerant is discharged from the outlet of the heat exchange tubes 61 and enters the first throttling device 30. Therefore, because the water collector 60 is installed between the outdoor heat exchanger 20 and the first throttling device 30, the water collector 60 can effectively reduce the temperature of the refrigerant discharged from the outdoor heat exchanger 20, thereby improving the air conditioning coefficient of performance.

[0117] Based on the aforementioned embodiment, the water collector 60 also includes a connecting plate 64. Multiple heat exchange fins 65 are arranged side-by-side at intervals. All heat exchange fins 65 are connected to the connecting plate 64. Thus, on the one hand, the multiple heat exchange fins 65 and the connecting plate 64 have a large contact surface with the outside, resulting in better heat dissipation, and also have a larger area to receive condensate, exhibiting better water absorption and storage characteristics; on the other hand, when the condensate is carried to the water collector 60 by the water-pumping ring 73, the condensate contacts the heat exchange fins 65, the connecting plate 64, and the heat exchange tubes 61 and flows downwards along their surfaces. The condensate lowers the temperature of the heat exchange fins 65, the connecting plate 64, and the heat exchange tubes 61, and can correspondingly remove heat from the heat exchange tubes 61.

[0118] For example, at least one of the heat exchange fins 65 and the connecting plate 64 is made of a hydrophilic material. This enables the water collector 60 to have water absorption, water storage, and water flow characteristics.

[0119] Specifically, the heat exchange fins 65 and the connecting plate 64 are both made of hydrophilic materials.

[0120] For example, at least one of the heat exchange fins 65 and the connecting plate 64 has a hydrophilic layer on its surface. This enables the water collector 60 to have water absorption, water storage, and water flow characteristics.

[0121] Specifically, the entire surface of the heat exchange fins 65 and the connecting plate 64 is provided with a hydrophilic layer.

[0122] Of course, as an alternative, the water collector 60 can also be installed between the outdoor heat exchanger 20 and the first throttling device 30 without being connected in series, meaning the water collector 60 does not need to be equipped with heat exchange pipe fittings 61. The water collector 60 mainly guides the accumulated condensate to the outdoor heat exchanger 20, which can also effectively reduce the temperature of the outdoor heat exchanger 20. For example, the water collector 60 can also be made of a material with a certain water absorption capacity, such as a sponge or sheet plastic, which absorbs and collects condensate while flowing it down to the lower outdoor heat exchanger 20.

[0123] For example, when a heat dissipation mechanism 95 is connected in series between the water collector 60 and the first throttling device 30, the heat dissipation mechanism 95, for example, dissipates heat from the electronic control component 94. The air conditioner may also include a second throttling device. The second throttling device is connected between the outlet of the water collector 60 and the inlet of the heat dissipation mechanism 95. In this way, the refrigerant flowing out of the water collector 60 enters the second throttling device, which further reduces the temperature of the refrigerant, resulting in a more ideal heat dissipation effect. Consequently, the lower-temperature refrigerant enters the heat dissipation mechanism 95, improving its heat dissipation effect. This effectively solves the problem of the controller failing to operate normally due to excessive temperature rise in high-temperature environments, allowing the air conditioner to operate normally at high frequencies and improving its cooling capacity.

[0124] Please refer to the following: Figures 13 to 15 Because the space above the water-flushing ring 73 is not large enough, and more condensate is stirred up in the area above the outlet side of the water-flushing ring 73, while less condensate is stirred up in the area above the other side, the water collector 60 is arranged in the area above the outlet side of the water-flushing ring 73 to collect as much condensate as possible. Furthermore, the width of the water collector 60 along the left-right direction of the air conditioner is W1, and W1 is as large as space allows.

[0125] For example, the width of the outdoor air duct component 91 along the left-right direction of the air conditioner is W2, and W1 / W2 ≥ 1 / 3. Optionally, W1 / W2 may include, but is not limited to, 1 / 3, 1 / 2, 2 / 3 or 1, etc., and the specific size can be flexibly adjusted and set according to actual needs.

[0126] For example, the length of the water collector 60 along the front-rear direction of the air conditioner is the same as the length of the top wall of the outdoor air duct 91 along the front-rear direction and they are aligned with each other along the width direction.

[0127] Please see Figures 13 to 16 In one specific embodiment, the outdoor air duct component 91 can be equipped with both a water-blocking component and a water collector 60. The water collector 60 can collect more of the condensate that is thrown up and direct it downstream onto the outdoor heat exchanger 20. For details, please refer to [reference needed]. Figure 14Viewed from the back to the front of the air conditioner, the rotation direction of the water-spraying ring 73 is, for example, counterclockwise. The condensate water splashed up by the water-spraying ring 73 first shoots towards the reflective surface 9111 of the water-blocking component, which is specifically set as a vertical side surface; then it gradually rises to the upper left corner of the main casing 82. The water collector 60 can absorb the splashed condensate water. The water collector 60 is placed at an angle so that its bottom is positioned above or in contact with the outdoor heat exchanger 20. The water collector 60 absorbs and collects the condensate water to the top of the outdoor heat exchanger 20.

[0128] Please see Figure 14 and Figure 16 For example, the top wall of the outdoor air duct component 91 is provided with a guide member 912. Along the front-rear direction of the air conditioner, the distance between the guide member 912 and the bottom wall of the water storage tank 811 decreases, and the bottom end of the guide member 912 (i.e., the lowest point of the guide member 912) abuts against and / or is located above the outdoor heat exchanger 20. In this way, the condensate water blown up by the water ring 73 to the space above the outdoor air duct component 91 can be intercepted by the guide member 912 and guided to the outdoor heat exchanger 20 under its own gravity, which can reduce the temperature of the outdoor heat exchanger 20 and improve energy efficiency.

[0129] For example, the guide member 912 is located in the space above the return water side of the water ring 73. That is, the guide member 912 and the water collector 60 are located on opposite sides of the water ring 73, which is a reasonable layout that can reduce space and make full use of the condensate.

[0130] For example, the flow guide 912 is provided with a flow guide groove 9120, which extends along the flow direction of the flow guide 912, and a drain outlet is formed at the bottom end of the flow guide 912. In this way, the condensate intercepted and collected by the flow guide 912 will converge in the flow guide groove 9120, be guided downward through the flow guide groove 9120, and be discharged to the outdoor heat exchanger 20 through the drain outlet, which can prevent the condensate from overflowing in the middle and improve the flow guiding effect of the condensate.

[0131] Optionally, the length and width of the cross-sectional profile along the extension direction of the guide channel 9120 are both set to, for example, 3mm to 5mm. In this way, the length and width dimensions are not too small, which would cause the condensate to overflow midway, nor too large, which would lead to wasted guide space (there is not enough condensate). The goal is to satisfy the requirements of interception, guide, and no overflow.

[0132] Please see Figure 16For example, the flow guide 912 includes a first flow guide wall 9121, a second flow guide wall 9122, and a third flow guide wall 9123. The top side of the first flow guide wall 9121 is connected to the top wall of the outdoor air duct 91, the bottom side of the first flow guide wall 9121 is connected to the second flow guide wall 9122, the second flow guide wall 9122 is connected to the bottom side of the third flow guide wall 9123, and the top side of the third flow guide wall 9123 is provided with a water inlet gap with the outdoor air duct 91. The first flow guide wall 9121, the second flow guide wall 9122, and the third flow guide wall 9123 enclose and form a flow guide groove 9120. In this way, the condensate water raised by the water ring 73 to the upper space will enter through the water inlet gap, be intercepted by the first flow guide wall 9121, and flow into the flow guide groove 9120, and then flow downwards at an angle to the outdoor heat exchanger 20.

[0133] The arrangement direction of the first guide wall 9121 and the third guide wall 9123 is opposite to the rotation direction of the water-spraying ring 73. In this way, the condensate agitated by the water-spraying ring 73 will smoothly enter the guide groove 9120 through the water inlet gap.

[0134] In summary, in this embodiment, the condensate is reflected to the outdoor heat exchanger 20 by the water baffle, the condensate is collected and channeled to the outdoor heat exchanger 20 by the water collector 60, and the condensate is intercepted and channeled to the outdoor heat exchanger 20 by the flow guide 912. This allows a large amount of condensate to be poured onto the outdoor heat exchanger 20, making better use of the condensate to cool the outdoor heat exchanger 20 and improving the air conditioning capacity and energy efficiency.

[0135] Please see Figures 13 to 15 For example, the outdoor air duct component 91 also includes an air guide structure 913. The air guide structure 913 is, but is not limited to, a plate or similar component. The air guide structure 913 and the water baffle are located on opposite sides of the water-spraying ring 73. The end of the air guide structure 913 facing away from the outdoor fan 70 abuts against one end plate 22 of the outdoor heat exchanger 20, and the end of the water baffle facing away from the outdoor fan 70 abuts against the other end plate 22 of the outdoor heat exchanger 20, as detailed below. Figure 13 As shown, it should be noted that, Figure 13 To clearly demonstrate the interaction between the two end plates 22 of the outdoor heat exchanger 20 and the air guide structure 913 and water baffle, the main structure of the outdoor heat exchanger 20 is concealed. Both the air guide structure 913 and the water baffle function to guide airflow, ensuring that the air outlet of the outdoor fan 70 is directed to the outdoor heat exchanger 20, thereby improving the cooling effect of the outdoor heat exchanger 20.

[0136] Please refer to the following: Figure 4 and Figure 5For example, the air conditioner also includes a collection tray 83. The collection tray 83 is located within the chassis 81, below the indoor heat exchanger 40, and is used to collect condensate generated by the indoor heat exchanger 40. The collection tray 83 has a discharge section for discharging the condensate in the collection tray 83 into a water storage tank 811. Thus, condensate generated during the operation of the indoor heat exchanger 40 falls into the collection tray 83 and is collected there. The condensate collected in the collection tray 83 can be discharged into the water storage tank 811 through the discharge section, where it can be utilized by the water-cooling ring 73.

[0137] For example, the discharge section includes a discharge housing 84, which has a discharge trough 841. One end of the discharge trough 841 communicates with a collection tray 83, and the other end extends to a water storage tank 811. Thus, the condensate collected in the collection tray 83 can be discharged into the water storage tank 811 through the discharge trough 841. To facilitate the smooth discharge of condensate into the water storage tank 811, the bottom wall height of the discharge trough 841 decreases along the discharge direction.

[0138] For example, the collection tray 83 and the water storage tank 811 are arranged along the front-to-back direction of the air conditioner. Taking the normal installation and use of the air conditioner as a reference, the bottom wall of the chassis 81 corresponding to the collection tray 83 is higher than the bottom wall of the water storage tank 811, which facilitates the collection of condensate in the chassis 81 into the water storage tank 811, thus ensuring its full utilization. Alternatively, as an option, a water-blocking structure can be provided between the bottom wall of the chassis 81 corresponding to the collection tray 83 and the bottom wall of the water storage tank 811. This water-blocking structure can be, for example, ribs protruding from the bottom wall of the chassis 81. The water-blocking structure acts as a barrier, preventing condensate in the water storage tank 811 from flowing out to other parts of the chassis 81.

[0139] For example, the side wall of the chassis 81 is provided with an overflow port 812 corresponding to the water storage tank 811. When the condensate level in the water storage tank 811 is higher than the overflow port 812, it will be discharged outward in a timely manner through the overflow port 812 and the drain pipe connected to the overflow port 812, thereby maintaining the liquid level in the water storage tank 811 within the normal range and preventing leakage defects caused by condensate overflowing from other areas.

[0140] For example, a gap is provided between the collection tray 83 and the water storage tank 811 in the front-to-back direction. The compressor 10 is arranged in the gap. The discharge housing 84 extends through the gap to the water storage tank 811. In order to avoid various components such as the compressor 10 installed in the gap, the discharge housing 84 is specifically provided, for example, on the side of the chassis 81.

[0141] For example, the discharge section preferably discharges condensate to the return water side of the water-spraying ring 73. Specifically, the end of the discharge trough 841 extends to the return water side of the water-spraying ring 73. In this way, the condensate at the return water side of the water-spraying ring 73 can be replenished in a timely manner, which helps to maintain the liquid level in the first recess 8112 within the target range, and further helps to ensure that the water-spraying ring 73 can continuously spray water.

[0142] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0143] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0144] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0145] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0146] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0147] The technical features of the above embodiments can be combined in any way. For the sake of brevity, 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, they should be considered to be within the scope of this specification.

[0148] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
