The first drainage channel is inclined relative to the horizontal plane to have a high end and a low end. The high end of the first drainage channel is connected to the first accommodating chamber, and the low end of the first drainage channel is connected to the second accommodating chamber to drain the condensed water caused by the evaporator in the first accommodating chamber from the high end to the condenser through the first drainage channel.

[0009] In a possible implementation, the condenser is disposed in the second accommodating chamber along a horizontal direction, and the evaporator is disposed in the first accommodating chamber along a vertical direction.

[0010] In one possible implementation, a condensate inlet is provided at the high end of the first drainage channel, and the condensate inlet is connected to the first accommodating chamber; a condensate outlet is provided at the low end of the first drainage channel, and the condensate outlet extends in a direction close to the condenser and is connected to the second accommodating chamber.

[0011] In a possible implementation, a fan assembly is included, and the fan assembly is disposed in the second accommodating cavity, and an air outlet of the fan assembly faces the condenser.

[0012] In a possible implementation, the fan assembly includes a fan cover and a centrifugal fan. The fan cover is disposed on a housing, the centrifugal fan is connected to the fan cover, and the condensate outlet penetrates the housing and extends toward an inner wall of the fan cover.

[0013] In a possible implementation, a first groove is provided on the fan cover, a first end of the first groove is communicated with the condensate outlet, and a second end of the first groove is extended along the rotation direction of the fan.

[0014] In a possible implementation, the first accommodating chamber is provided with a water receiving tray, the water receiving tray is arranged below the evaporator, a second groove is provided on the water receiving tray, and the second groove is connected to the first drainage channel.

[0015] In a possible implementation, the drainage component includes a second drainage channel, and the second drainage channel includes a connected straight drainage segment and an arc drainage segment;

[0016] The straight drainage section is inclined relative to the horizontal direction, the first end of the straight drainage section is higher than the second end of the straight drainage section, the first end of the straight drainage section is connected to the box, and the second end of the straight drainage section is connected to the condensate inlet;

[0018] In one possible implementation, an outer cover is provided on the box body, and an air inlet and an air outlet are provided on the outer cover. The air inlet and the air outlet are arranged adjacent to each other or at intervals. The air inlet is arranged close to the fan, and the air outlet is arranged far away from the fan. The air inlet is located in a horizontal plane, and the air outlet is located in a vertical plane.

[0019] In a possible implementation, a partition is included, and the partition is arranged in the first accommodating chamber. The fan assembly and the evaporator are respectively arranged on both sides of the evaporator.

[0020] The above technical solution provided by the embodiment of the present application has the following advantages compared with the prior art:

[0021] The window air conditioner provided in the embodiment of the present application has an evaporator fixedly installed in the first accommodating chamber of the box body, and a condenser fixedly installed in the second accommodating chamber of the box body. Since the first accommodating chamber and the second accommodating chamber are staggered in the vertical direction, after the window air conditioner is installed, the evaporator and the condenser are staggered in the vertical direction, that is, the evaporator is located in the upper space of the window air conditioner, and the condenser is located in the lower space of the window air conditioner (which is the lowest position of the window air conditioner). During the operation of the window air conditioner, the evaporator causes the ambient temperature in the first accommodating chamber to be relatively low, so that condensed water condenses on the inner wall of the box body and the outer surface of the evaporator refrigerant pipe due to the low ambient temperature. The condensed water flows from top to bottom along the outer surface of the box body under the action of its own gravity and gathers in the first accommodating chamber. Since the first drainage channel is inclined relative to the horizontal plane, the first drainage channel drains the condensed water in the first accommodating chamber from the high end of the first drainage channel to the low end of the first drainage channel. Then, this part of the condensed water flows into the condenser of the second accommodating chamber under the action of its own gravity, so that the condenser and the condensed water exchange heat. Since the evaporator and the condenser are staggered in the vertical direction, the height difference between the two can be used to drain the condensed water to the top of the condenser through the first drainage channel. The condensed water naturally slides down under the action of its own gravity, or flows on the outer surface of the condenser with the assistance of the blowing of external wind, thereby increasing the contact area between the condensed water and the condenser, and improving the effective utilization rate of the condensed water, thereby improving the heat exchange efficiency of the condenser and improving the overall energy efficiency of the window air conditioner.

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0036] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0037] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0038] In the related art, due to the low surface temperature of the evaporator, condensed water with a low temperature is generated when exchanging heat with the indoor air, and the condensed water flows to the outdoor side through the water receiving tray and the bottom plate. Some window air conditioners will soak the U-shaped tube at the bottom of the condenser in condensed water to achieve the purpose of utilizing the cooling capacity of the condensed water, but in general, the utilization rate of the condensed water is still low. In the window air conditioner disclosed in CN220793295U, the condensed water is pumped to the water pumping ring of the outdoor centrifugal fan by a water pump, and the condensed water is pumped to the condenser, but the newly added water pump will consume more power and the energy saving effect will be discounted; CN105444283A discloses an auxiliary condenser, which is placed above the outdoor axial flow centrifugal fan to increase the efficiency of the axial flow centrifugal fan pumping water, but the auxiliary condenser of this structure has the problem of being difficult to fix and install due to the inclination angle between it and the main condenser, and the stress at the connection with the main condenser is too large. In summary, the existing window air conditioner has a technical problem that the utilization rate of condensed water is low, resulting in too low heat exchange efficiency of the condenser, which affects the overall energy efficiency of the window air conditioner.

[0039] In order to solve the technical problem that the utilization rate of condensed water in the existing window air conditioner is low, resulting in too low heat exchange efficiency of the condenser, affecting the overall energy efficiency of the window air conditioner, the present application provides a window air conditioner. Since the evaporator and the condenser are staggered in the vertical direction, the first drainage channel can utilize the height difference between the two to drain the condensed water to the upper surface of the condenser. The condensed water flows on the outer surface of the condenser under the action of its own gravity or external wind, which increases the contact area between the condensed water and the condenser, improves the effective utilization rate of the condensed water, thereby improving the heat exchange efficiency of the condenser, and then improving the overall energy efficiency of the window air conditioner.

[0040] like Figure 1 to Figure 2 As shown, a window air conditioner 100 provided in the present application includes a housing 1, an evaporator 2, a condenser 3 and a drainage assembly 4, the housing 1 includes a first accommodating chamber 11 and a second accommodating chamber 12 connected to each other, the first accommodating chamber 11 and the second accommodating chamber 12 are staggered in the vertical direction; the evaporator 2 is arranged in the first accommodating chamber 11; the condenser 3 is arranged in the second accommodating chamber 12; the drainage assembly 4 includes a first drainage channel 41, the first drainage channel 41 is arranged on the housing 1, the first drainage channel 41 is inclined relative to the horizontal plane to have a high end and a low end, the high end of the first drainage channel 41 is connected to the first accommodating chamber 11, and the low end of the first drainage channel 41 is connected to the second accommodating chamber 12, so as to drain the condensed water caused by the evaporator 2 in the first accommodating chamber 11 from the high end through the first drainage channel 41 to the condenser 3.

[0041] For ease of explanation and understanding, the vertical direction may be the Z direction shown in the figure, and the two sides of the vertical direction are respectively the upper and lower shown in the figure, and the height direction of the first accommodating chamber 11 is parallel to the vertical direction. It can be understood that the first accommodating chamber 11 and the second accommodating chamber 12 are staggered in the vertical direction, and are specifically arranged such that the second accommodating chamber 12 is arranged below the first accommodating chamber 11, the first end of the second accommodating chamber 12 is connected to the first accommodating chamber 11, and the second end of the second accommodating chamber 12 is extended along the height direction of the first accommodating chamber 11, so that the box body 1 is an "L"-shaped structure as a whole. The evaporator 2 is fixedly installed in the first accommodating chamber 11 of the box body 1, and the condenser 3 is fixedly installed in the second accommodating chamber 12 of the box body 1. Since the first accommodating chamber 11 and the second accommodating chamber 12 are staggered in the vertical direction, after the window air conditioner 100 is installed, the evaporator 2 and the condenser 3 are staggered in the vertical direction, such as Figure 1 As shown, the evaporator 2 is located in the upper space of the window air conditioner 100, and the condenser 3 is located in the lower space of the window air conditioner 100 (which is the lowest position of the window air conditioner 100).

[0042] During the operation of the window air conditioner 100, the evaporator 2 causes the ambient temperature in the first accommodating chamber 11 to be low, so that condensed water is condensed on the inner wall of the cabinet 1 and the outer surface of the refrigerant pipe of the evaporator 2 due to the low ambient temperature. The condensed water flows from top to bottom along the outer surface of the cabinet 1 under the action of its own gravity and gathers in the first accommodating chamber 11. Since the first drainage channel 41 is inclined relative to the horizontal plane, the first drainage channel 41 drains the condensed water in the first accommodating chamber 11 from the high end of the first drainage channel 41 to the low end of the first drainage channel 41. Then, this part of the condensed water flows under the action of its own gravity. The water flows downward into the condenser 3 of the second accommodating chamber 12, so that the condenser 3 exchanges heat with the condensed water. Since the evaporator 2 and the condenser 3 are staggered in the vertical direction, the first drainage channel 41 can utilize the height difference between the two to drain the condensed water to the top of the condenser 3. The condensed water naturally slides down under the action of its own gravity, or flows on the outer surface of the condenser 3 with the assistance of external wind force, thereby increasing the contact area between the condensed water and the condenser 3 and improving the effective utilization rate of the condensed water, thereby improving the heat exchange efficiency of the condenser 3 and improving the overall energy efficiency of the window air conditioner 100.

[0043] The housing 1 and the first drainage channel 41 can be made of the same material, or different materials can be used for the housing 1 and the first drainage channel 41. In a preferred example, the housing 1 and the first drainage channel 41 are integrally formed to reduce production processes and improve the overall structural strength of the window air conditioner 100.

[0044] In a preferred embodiment, Figure 1 As shown, the condenser 3 is arranged at the second end of the second accommodating chamber 12 in the horizontal direction, and the evaporator 2 is arranged at one end of the first accommodating chamber 11 away from the second accommodating chamber 12 in the vertical direction. It can be understood that placing the condenser 3 horizontally upside down at the bottom of the second accommodating chamber 12 can increase the contact area between the condenser 3 and the condensed water, and facilitate the installation of the fan assembly 5, which can effectively utilize the vertical space of the second accommodating chamber 12 and shorten the size of the second accommodating chamber 12 in its width direction. The width direction is the X direction shown in the figure, so that the overall size of the window air conditioner 100 is smaller. The evaporator 2 is arranged in the first accommodating chamber 11 in the vertical direction. Since the evaporator 2 needs to be installed on the indoor side, the coldness of the evaporator 2 is used to cool the indoor temperature. Such a design makes it convenient for the staff to install the window air conditioner 100.

[0045] The window air conditioner 100 has a wide range of application scenarios in modern home environments. In small apartments, the space is very limited and every inch of space is precious. This compact window air conditioner 100 can be easily installed on the window of the bedroom or living room, which does not take up too much indoor floor space, and can efficiently adjust the indoor temperature to create a comfortable living environment for the residents. In some old residential buildings, due to the limitations of the building structure, there may be no special air conditioner outdoor unit reserved, and the window air conditioner 100 has become an excellent choice. Its integrated design can better adapt to the size of the window by reasonably utilizing the vertical space to reduce the size of the whole machine, and it is easy to install and does not affect the appearance of the building. In small offices or shops, the window air conditioner 100 can also play an important role. It can quickly cool and heat, maintain a suitable temperature in a limited space, provide a comfortable working environment for staff, or create a pleasant shopping atmosphere for customers, and its smaller overall size will not cause too much interference with the indoor layout and display, which is convenient for merchants to flexibly place product display racks or office furniture according to their own needs.

[0046] The reduction in the size of the second accommodating cavity 12, especially the reduction in the width direction, has a very critical impact on the overall structural layout of the window air conditioner 100. It can effectively reduce the size of the window air conditioner 100 in terms of the overall size, so that the window air conditioner 100 can occupy a smaller space in the installation and use scenario, which is more in line with the modern home's demand for miniaturization and refinement of electrical appliances. At the same time, it is also beneficial to reduce production costs and space occupation during transportation and other aspects of efficiency improvement to a certain extent.

[0047] It should be noted that, in some embodiments, the condenser 3 may also be provided with a second end of the second accommodating chamber 12 in the vertical direction. When the window air conditioner 100 operates in a cooling mode, the low-temperature and low-pressure gaseous refrigerant generated by the evaporator 2 is compressed into a high-temperature and high-pressure gas by the compressor 8 and then enters the condenser 3. During this process, the condenser 3 can also be provided with a second end of the second accommodating chamber 12 in the vertical direction. The condensed water in the first accommodating chamber 11 is accelerated by the first drainage channel 41 and flows to the outer surface of the condenser 3. Due to the influence of its own gravity, the condensed water will slide down along the outer surface of the condenser 3 more smoothly, so that the condensed water covers a wider range on the surface of the condenser 3, greatly increasing the contact area between the condensed water and the condenser 3; and a larger contact area means that there are more and more sufficient media for heat exchange, thereby effectively improving the heat exchange efficiency of the condenser 3 in the entire heat exchange system, allowing the condenser 3 to better dissipate heat, ensuring the stable operation of the air conditioner, and continuously providing a comfortable cooling environment for the room. However, the air outlet 132 of the fan assembly 5 needs to face the condenser 3. Such a design will increase the size of the second accommodating chamber 12 in its width direction, making the overall size of the window air conditioner 100 larger. Of course, in some embodiments, the second end of the second accommodating chamber 12 of the condenser 3 can also be tilted relative to the horizontal direction. On the one hand, the condensed water can slide along the outer surface of the condenser 3 under the action of its own gravity, and on the other hand, the size of the second accommodating chamber 12 in its width direction can be minimized, so that the overall size of the window air conditioner 100 is relatively small.

[0048] In one embodiment, Figure 3 and Figure 4 As shown, the high end of the first drainage channel 41 is provided with a condensed water inlet 411, which is connected to the first accommodation chamber 11; the low end of the first drainage channel 41 is provided with a condensed water outlet 412, which is arranged along the direction close to the condenser 3 and is connected to the second accommodation chamber 12. It can be understood that since the condensed water inlet 411 of the first drainage channel 41 is higher than the condensed water outlet 412 of the first drainage channel 41, condensed water is condensed on the inner wall of the box body 1 and the outer surface of the refrigerant pipe of the evaporator 2 due to the low ambient temperature, and the condensed water flows from top to bottom along the outer surface of the box body 1 under the action of its own gravity and gathers in the first accommodation chamber 11, and the condensed water in the first accommodation chamber 11 flows from the condensed water inlet 411 of the first drainage channel 41 to the condensed water outlet 412 of the first drainage channel 41, and then this part of the condensed water flows into the condenser 3 under the action of its own gravity, so that the condenser 3 and the condensed water are heat exchanged.

[0049] Optionally, the condensate inlet 411 is connected to the first accommodating chamber 11 in such a way that the condensate inlet 411 passes through the box body 1 and communicates with the first accommodating chamber 11 ; the condensate outlet 412 is connected to the second accommodating chamber 12 in such a way that the condensate outlet 412 passes through the box body 1 and communicates with the second accommodating chamber 12 .

[0050] In the actual design and application process, there are many options for the shapes of the condensate inlet 411 and the condensate outlet 412. The condensate inlet 411 and the condensate outlet 412 can be set to a circular shape. The circular structure can make the condensate circulate more smoothly when flowing in or out, reducing the water flow resistance, and it is relatively simple to process and manufacture, and can be achieved through conventional pipe cutting, bending and welding processes; it can also be an elliptical shape. The elliptical shape has unique advantages under certain specific spatial layouts or fluid dynamics requirements. The elliptical condensate inlet 411 and condensate outlet 412 can better adapt to the overall structural design, and at the same time, it can also show different characteristics from the circular shape in terms of water flow stability; it can also be set to a square shape. The square design is suitable for some places that need to be connected with other square parts or devices. It is more convenient to connect and integrate the equipment, and its flat edge is easy to connect and fix. In addition, the square condensate inlet and outlet can be operated more conveniently by operators during installation and maintenance. For example, when cleaning the pipeline or replacing the seal, the square opening provides a wider operating space. It can even adopt a trapezoidal shape. The trapezoidal structure can flexibly adjust the size ratio of the upper and lower bottoms according to the specific internal structure differences of the equipment to meet the requirements of different flow rates, pressures and installation positions. For example, in some equipment that is installed at an angle or requires special control of the condensate flow, the trapezoidal condensate inlet and outlet can achieve precise control of the water flow by changing the angle and side length of the trapezoid. The present application does not impose specific restrictions on the shape of the condensate inlet 411 and the condensate outlet 412. The user can decide on his own what shape of the condensate inlet 411 and outlet to adopt after comprehensive consideration of multiple factors such as actual engineering needs, equipment characteristics, cost budget, and fluid mechanics calculations, so as to achieve the best operating effect and economic benefits.

[0051] Of course, this embodiment can also be combined with the above-mentioned embodiment. In an optional embodiment, the condensate outlet 412 is arranged to extend in the direction close to the condenser 3 and connected to the first end of the second accommodating chamber 12. The condenser 3 is arranged at the second end of the second accommodating chamber 12 in the horizontal direction. Through the above arrangement, the condensate in the first accommodating chamber 11 flows from the condensate inlet 411 of the first drainage channel 41 to the condensate outlet 412 of the first drainage channel 41. Since the condenser 3 is arranged at the second end of the second accommodating chamber 12 in the horizontal direction, this part of the condensate flows into the upper surface of the condenser 3 under the action of its own gravity. The condensate is affected by its own gravity or external wind force and then flows on the outer surface of the condenser 3, which increases the contact area between the condensate and the condenser 3 and improves the effective utilization rate of the condensate, thereby improving the heat exchange efficiency of the condenser 3 and improving the overall energy efficiency of the window air conditioner 100.

[0052] In one embodiment, Figure 1 As shown, the window air conditioner 100 includes a fan assembly 5, which is arranged in the second accommodating chamber 12, and the air outlet of the fan assembly 5 faces the condenser 3. During the normal operation of the window air conditioner 100, the fan assembly 5 inhales the air from the outdoor side, and uses the principle of forced convection to make the condenser 3 and the air exchange heat, thereby reducing the refrigerant temperature of the condenser 3 and improving the heat exchange efficiency of the condenser 3. After the condensed water generated by the evaporator 2 is drained to the condenser 3 through the first drainage channel 41, the fan assembly 5 can blow away the condensed water flowing to the condenser 3, which can increase the contact area between the condensed water and the condenser 3 on the one hand, and increase the evaporation rate of the condensed water on the other hand, so that the heat exchange efficiency between the condensed water and the condenser 3 is greatly improved, and the overall energy efficiency of the window air conditioner 100 is further improved.

[0053] Furthermore, the condenser 3 is horizontally arranged at the second end of the second accommodating chamber 12, and the fan assembly 5 is located directly above the condenser 3, so that the air outlet of the fan assembly 5 faces the condenser 3. With such a design, the vertical space of the second accommodating chamber 12 can be effectively utilized, and there is no need to reserve too much arrangement space for the condenser 3 and the fan assembly 5 in the width direction, so that the size of the second accommodating chamber 12 in its width direction can be significantly shortened, thereby reducing the overall size of the window air conditioner 100.

[0054] In one embodiment, Figure 2As shown, the fan assembly 5 includes a fan cover 51 and a centrifugal fan 52 . The fan cover 51 is arranged on the box body 1 , and the centrifugal fan 52 is connected to the fan cover 51 . The condensate outlet 412 penetrates the box body 1 and extends to the inner wall of the fan cover 51 . It can be understood that the condensed water generated by the evaporator 2 flows from top to bottom along the outer surface of the casing 1 under the action of its own gravity and gathers in the first accommodating chamber 11. The condensed water in the first accommodating chamber 11 flows from the condensed water inlet 411 of the first drainage channel 41 to the condensed water outlet 412 of the first drainage channel 41. Since the condensed water outlet 412 penetrates the casing 1 and extends to the inner wall of the fan cover 51, the condensed water flows downward along the inner wall of the fan cover 51. The centrifugal fan 52 can blow away a part of the condensed water, and the condensed water is scattered in different areas on the surface of the condenser 3. Furthermore, the centrifugal fan 52 can also blow away the condensed water flowing onto the condenser 3. The condensed water exchanges heat with the condenser 3 during the flow process, thereby increasing the contact area between the condensed water and the condenser 3. On the other hand, the evaporation rate of the condensed water can be increased, so that the heat exchange efficiency between the condensed water and the condenser 3 is greatly improved, and the overall energy efficiency of the window air conditioner 100 is further improved.

[0055] The centrifugal fan 52 is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. Based on the principle of converting kinetic energy into potential energy, the centrifugal fan 52 uses a high-speed rotating impeller to accelerate the gas, then decelerate and change the flow direction, so that the kinetic energy is converted into potential energy (pressure). In the single-stage centrifugal fan 52, the gas enters the impeller axially, changes to radial when passing through the impeller, and then enters the diffuser. In the diffuser, the gas changes the flow direction and the cross-sectional area of ​​the pipeline increases to decelerate the airflow. This deceleration effect converts kinetic energy into pressure energy, so that the centrifugal fan 52 can provide a relatively large air volume and pressure with lower energy consumption. The centrifugal fan 52 provides a large air volume to the first opening of the fan cover 51, thereby increasing the evaporation rate of the condensed water and improving the heat exchange efficiency between the condenser 3 and the condensed water.

[0056] Optionally, the fan cover 51 as a whole can be set to an inverted trumpet shape, specifically, the cross-sectional shape of the fan cover 51 can be set to a sine wave. The two ends of the fan cover 51 respectively have a first opening and a second opening, the cross-sectional area of ​​the first opening is smaller than the cross-sectional area of ​​the second opening, and the centrifugal fan 52 is arranged at the first opening of the fan cover 51. Then, the fan cover 51 can also guide the airflow leaving the inside of the centrifugal fan 52, and the airflow enters the inside of the fan cover 51 evenly, reducing the eddy loss on the blades of the centrifugal fan 52, while improving the separation loss generated by the trailing edge, improving the aerodynamic efficiency of the centrifugal fan 52, and reducing the noise generated by the airflow.

[0057] When the above-mentioned fan cover 51 is specifically prepared, the material of the fan cover 51 is not limited. The material of the fan cover 51 can be metal or plastic, such as acrylonitrile-butadiene-styrene copolymer (ABS), engineering plastic alloy (PC+ABS), polyamide 6 (PA6), polyhexamethylene adipamide (PA66), glass fiber reinforced polybutylene terephthalate (PBT+glass fiber), glass fiber reinforced polycarbonate (PC+glass fiber), polyphosphate (PPE) or polypropylene (PP).

[0058] In one embodiment, Figure 5 As shown, the inner side wall of the fan cover 51 is provided with a first groove 511, the first end of the first groove 511 is communicated with the condensed water outlet 412, and the second end of the first groove 511 is extended and arranged along the rotation direction of the centrifugal fan 52. Specifically, the first groove 511 is obliquely arranged on the inner side wall of the fan cover 51, and the inclination direction of the first groove 511 is related to the rotation direction of the centrifugal fan 52. For example, when the fan blades of the centrifugal fan 52 rotate counterclockwise, the inclination direction of the first groove 511 is arranged in the counterclockwise direction; when the fan blades of the centrifugal fan 52 rotate clockwise, the inclination direction of the first groove 511 is arranged in the clockwise direction. Through the above-mentioned structural design, a part of the condensed water is blown away and falls onto the condenser 3 at the condensed water outlet 412, and the other part of the condensed water flows into the first groove 511 along the condensed water outlet 412 of the first drainage channel 41. That is to say, the condensed water passes through the first acceleration of the first drainage channel 41 and then passes through the second acceleration of the first groove 511. Under the action of the wind force of the centrifugal fan 52, this part of the condensed water has centrifugal force when leaving the inner wall of the fan cover 51, and the condensed water is blown away at the end of the first groove 511. The blown condensed water drops on different areas on the surface of the condenser 3, thereby increasing the contact area between the condensed water and the condenser 3, further improving the heat exchange efficiency of the condenser 3, and improving the overall energy consumption of the window air conditioner 100.

[0059] Furthermore, a plurality of first grooves 511 may be provided, and the inclination directions of the plurality of first grooves 511 are different. After being accelerated by the plurality of first grooves 511, the condensed water is blown away by the centrifugal fan 52 and drips onto different surfaces of the condenser 3. The first grooves 511 can control the dripping direction of the condensed water, so that the condensed water splashes onto different areas of the surface of the condenser 3 under the action of centrifugal forces in different directions, thereby increasing the contact area between the condensed water and the condenser 3, further improving the heat exchange efficiency of the condenser 3, and improving the overall energy consumption of the window air conditioner 100.

[0060] In one embodiment, Figure 2As shown, the first accommodating chamber 11 is provided with a water receiving tray 6, which is arranged below the evaporator 2, and a second groove 61 is arranged on the water receiving tray 6, which is connected to the first drainage channel 41. The water receiving tray 6 is used to collect the condensed water collected in the first accommodating chamber 11. On the one hand, it can prevent the condensed water from flowing into the indoor side, which will cause the indoor environment to become humid, which may damage the surrounding items and even cause users to be dissatisfied and complain about the experience of using the equipment; on the other hand, the second groove 61 can also play a drainage role. The second groove 61 of the water receiving tray 6 drains the condensed water in the first accommodating chamber 11 into the first drainage channel 41, so that the condensed water exchanges heat with the condenser 3, and the condensed water is effectively used.

[0061] In one embodiment, Figure 3 and Figure 4 As shown, the drainage assembly 4 includes a second drainage channel 42, and the second drainage channel 42 includes a connected straight drainage section 421 and an arc drainage section 422; the straight drainage section 421 is inclined relative to the horizontal direction, the first end of the straight drainage section 421 is higher than the second end of the straight drainage section 421, the first end of the straight drainage section 421 is connected to the box body 1, and the second end of the straight drainage section 421 is connected to the condensed water inlet 411; the first end of the arc drainage section 422 is connected to the second groove 61, and the second end of the arc drainage section 422 is connected to the condensed water inlet 411. By setting the straight drainage section 421, the first end of the straight drainage section 421 is higher than the second end of the straight drainage section 421, and the straight drainage section 421 introduces the condensed water from the second end of the straight drainage section 421 into the condensed water inlet 411 of the first drainage channel 41, so as to prevent the condensed water from being affected by external force vibration and flowing to the outer wall of the fan cover 51, resulting in waste of condensed water. The arc drainage section 422 can also play a drainage role, so that the condensed water flows from the second end of the arc drainage section 422 into the condensed water inlet 411 of the first drainage channel 41. The condensed water flows from the condensed water inlet 411 of the first drainage channel 41 to the condensed water inlet 411 of the first drainage channel 41. Since the condenser 3 is arranged at the second end of the second accommodating chamber 12 in the horizontal direction, this part of the condensed water flows into the upper surface of the condenser 3 under the action of its own gravity. The condensed water is affected by its own gravity or the external wind force and then flows on the outer surface of the condenser 3, which increases the contact area between the condensed water and the condenser 3, improves the effective utilization rate of the condensed water, thereby improving the heat exchange efficiency of the condenser 3 and improving the overall energy efficiency of the window air conditioner 100.

[0062] like Figure 7 As shown, the air inlet 201 and the air outlet 202 on the outdoor side of the current window air conditioner 200 are at the same height and close to each other. The hot air blown out by the condenser is more easily re-inhaled by the air inlet 201, resulting in a higher temperature of the air actually exchanging heat with the condenser, reducing the heat exchange efficiency and making the energy efficiency of the whole machine lower.

[0063] In one embodiment, Figure 6 As shown, the housing 1 is provided with an outer cover 13, and the outer cover 13 is provided with an air inlet 131 and an air outlet 132. The air inlet 131 is provided near the centrifugal fan 52 and communicates with the second accommodating chamber 12, and the air outlet 132 is provided near the condenser 3 and communicates with the second accommodating chamber 12; the air inlet 131 is arranged along a vertical plane, and the air outlet 132 is arranged along a horizontal plane. The air inlet 131 and the air outlet 132 on the outdoor side can be arranged at different heights, increasing the distance between the two, so that the outdoor side air inlet temperature is less affected by the outlet air, and the air inlet temperature can be reduced, making the air conditioner more energy-efficient as a whole.

[0064] The outer cover 13 is responsible for ventilation and heat dissipation. The air inlet 131 is arranged close to the centrifugal fan 52 and communicates with the second accommodation chamber 12. The distance between the two is strictly designed and optimized to ensure that when the centrifugal fan 52 starts to operate, the negative pressure suction force generated by the operation of the centrifugal fan 52 can efficiently suck the outside air into the second accommodation chamber 12 with minimal resistance loss to participate in the subsequent heat exchange process with the condenser 3. The air outlet 132 matching the air inlet 131 is arranged close to the condenser 3. Its main function is to carry the heat generated by the condenser 3 during the heat exchange process to the external environment, ensuring that the heat inside the box body 1 can be dissipated in a timely and efficient manner. From the perspective of spatial layout, the air inlet 131 is arranged along the vertical plane, and the air outlet 132 is arranged along the horizontal plane. This unique vertical arrangement, based on the principle of fluid mechanics, can make full use of the air pressure difference in the vertical direction, optimize the air inlet flow rate and flow distribution, and provide a stable and sufficient cold air source for the subsequent heat exchange process in the second accommodating chamber 12, so that the air entering the second accommodating chamber 12 has a better temperature condition in the initial stage, reducing the air inlet temperature, making the window air conditioner 100 more energy-efficient as a whole. At the same time, the air outlet 132 is arranged along the horizontal plane. According to the principle of hot air rising and air diffusion, such a horizontal arrangement design can make the air carrying heat disperse in a relatively uniform manner in the horizontal direction, greatly improving the coverage and efficiency of heat dissipation, and effectively avoiding the accumulation of local heat, thereby creating a stable and suitable temperature working environment inside the box 1, effectively ensuring the reliability and stability of the window air conditioner 100 during long-term operation, and significantly reducing the risk of equipment failure or performance degradation caused by high temperature overheating.

[0065] The air inlet 131 and the air outlet 132 can be respectively arranged on two adjacent sides of the outer cover 13. Since the box body 1 is in a unique "L" shape as a whole, that is, the height of the air inlet 131 is greater than the height of the air outlet 132, that is, the air inlet 131 is arranged as far away from the air outlet 132 as possible, which further avoids the air inlet 131 from sucking in the hot air blown out by the condenser 3 again, so that the air entering the second accommodating chamber 12 has a better temperature condition in the initial stage, thereby reducing the inlet air temperature and making the window air conditioner 100 more energy-efficient as a whole.

[0066] In one embodiment, the window air conditioner 100 includes a partition 7, which is arranged in the first accommodation chamber 11, and the fan assembly 5 and the evaporator 2 are respectively arranged on both sides of the evaporator 2. The function of the partition 7 is to separate the centrifugal fan 52 and the evaporator 2. After the air passes through the centrifugal fan 52, high-pressure air will be formed. When the high-pressure air flows into the first accommodation chamber 11 from the air inlet 131, heat exchange will occur in the boundary area where the partition 7 and the evaporator 2 are adjacent to each other. From the basic principle of heat transfer, the heat carried by the high-pressure air will interact with the surface of the evaporator 2 at the boundary in various ways such as heat conduction and heat convection. The evaporator 2 usually circulates a low-temperature refrigerant, and its temperature is much lower than the initial temperature of the high-pressure air. Therefore, the high-pressure air can be appropriately cooled to form low-temperature high-pressure air. This part of the high-pressure air exchanges heat with the condenser 3, takes away the heat of the condenser 3, and accelerates the evaporation rate of the condensed water on the surface of the condenser 3, thereby improving the heat exchange efficiency of the condenser 3 and improving the energy efficiency of the whole machine.

[0067] In one embodiment, the window air conditioner 100 includes a compressor 8, which is disposed in the first accommodating chamber 11. The exhaust port of the compressor 8 is connected to the refrigerant inlet of the condenser 3, and the air intake port of the compressor 8 is connected to the refrigerant outlet of the evaporator 2. The refrigerant outlet of the condenser 3 is connected to the refrigerant inlet of the throttling device, and the refrigerant outlet of the throttling device is connected to the refrigerant inlet of the evaporator 2. A refrigeration cycle is formed between the compressor 8, the condenser 3, the throttling device and the evaporator 2. The compressor 8 sucks low-pressure refrigerant from the evaporator 2, raises the refrigerant from low pressure to high pressure, and makes the refrigerant circulate continuously in the refrigeration cycle. The refrigerant is condensed into a refrigerant liquid with a higher pressure and a higher temperature in the condenser 3. This part of the refrigerant liquid enters the throttling device, and after being throttled by the throttling device, it is sent to the evaporator 2. The low-temperature refrigerant of the evaporator 2 exchanges heat with the air on the indoor side, thereby realizing the cooling of the indoor side. At the same time, the refrigerant absorbs heat and evaporates in the evaporator 2 to become a refrigerant vapor with a lower pressure. The refrigerant vapor enters the air inlet of the compressor 8 to realize the refrigerant circulation.

[0068] Optionally, the throttling device is used to throttle and reduce the pressure of the high-pressure refrigerant liquid from the condenser 3 to a low-pressure refrigerant liquid, and at the same time adjust the refrigerant flow entering the evaporator 2. When the throttling device is adjusted to the maximum opening, the refrigerant has a maximum flow in the refrigeration pipeline. The throttling device can be but is not limited to: a capillary tube, a throttling short tube, a thermal expansion valve, an electronic expansion valve, a float valve, a throttling orifice plate, a manual expansion valve, etc.
