Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a window air conditioner. Background Technology

[0002] In related technologies, window air conditioners collect condensate from the indoor heat exchanger during cooling operation and discharge it to the chassis of the outdoor unit. A water-scraping ring around the outdoor fan deflects the condensate onto the surface of the outdoor heat exchanger to aid heat dissipation and improve cooling capacity. However, during heating operation in winter, melted rainwater, snow, or defrost water from the outdoor heat exchanger accumulates in the chassis and freezes. This causes the water-scraping ring to collide with the ice, affecting the fan's operation and generating scraping noise. In severe cases, it can lead to the fan malfunctioning or being damaged.

[0048] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0049] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0050] Hereinafter, with reference to the accompanying drawings, a window air conditioner 100 according to a first aspect embodiment of the present invention will be described.

[0051] refer to Figure 1 The window air conditioner 100 includes a chassis component 1 and a main unit component 2. The chassis component 1 includes an inner chassis portion 11, an outer chassis portion 12, and a drain valve 13. A first water tank 121 and a second water tank 122 are formed on the outer chassis portion 12. The first water tank 121 and the second water tank 122 are both open at the top and isolated from each other. The inner chassis portion 11 is connected to the first water tank 121. The drain valve 13 is used to control the drainage of the first water tank 121. The main unit component 2 includes an outdoor heat exchanger 22 and a water-flushing ring 232. The rotation axis of the water-flushing ring 232 is horizontal and the bottom of the water-flushing ring 232 extends into the first water tank 121. At least a portion of the outdoor heat exchanger 22 is located above the second water tank 122. A heating element 25 is provided at the second water tank 122.

[0052] For example, the main unit 2 includes an indoor heat exchanger 21, which is located above the inner chassis portion 11. The inner chassis portion 11 has a drain outlet 111, which communicates with the first water tank 121. Thus, the inner chassis portion 11 can collect dripping water from the indoor heat exchanger 21 and drain water into the first water tank 121 through the drain outlet 111. Of course, the main unit 2 can also use a heat exchange device located in another position instead of the indoor heat exchanger 21. Furthermore, the inner chassis portion 11 can also be used to collect water from other sources. Additionally, the inner chassis portion 11 can communicate with the first water tank 121 through other means besides the drain outlet 111, such as through a pipe connection. However, for the sake of simplicity, this description primarily uses the example of the main unit 2 including an indoor heat exchanger 21, located above the inner chassis portion 11, with a drain outlet 111 communicating with the first water tank 121.

[0053] For example, the first water tank 121 has a water outlet 1215, and a drain valve 13 is disposed at the water outlet 1215 to open and close the water outlet 1215. This allows the drain valve 13 to control the drainage of the first water tank 121. However, this application is not limited to this; a pipe can also be connected to the first water tank 121, and the drain valve 13 can control the opening and closing of the pipe to achieve drainage control. The window air conditioner 100 also includes a drainage path communicating with the second water tank 122, thereby enabling drainage of the second water tank 122. This drainage path is not limited and can be in the form of a water hole or a water pipe. However, for the sake of simplicity, this article mainly uses the example of the first water tank 121 having a water outlet 1215 and the drain valve 13 being disposed at the water outlet 1215 to open and close the water outlet 1215.

[0054] For example, the main unit 2 includes an outdoor fan 23, which is located above the outer chassis portion 12. The outdoor fan 23 includes a rotatable water-spraying ring 232. Thus, by integrating the water-spraying ring 232 with the outdoor fan 23, the structure can be simplified and the drive required can be reduced. Of course, this application is not limited to this; the water-spraying ring 232 can also be installed independently of the outdoor fan 23. However, for the sake of simplicity, this document mainly uses the example of the main unit 2 including the outdoor fan 23, the outdoor fan 23 being located above the outer chassis portion 12, and the outdoor fan 23 including a rotatable water-spraying ring 232 for illustration.

[0055] In one specific embodiment of this application, the window air conditioner 100 includes a chassis component 1 and a main unit component 2. The chassis component 1 includes an inner chassis portion 11, an outer chassis portion 12, and a drain valve 13. A first water tank 121 and a second water tank 122 are formed on the outer chassis portion 12. The first water tank 121 and the second water tank 122 are both open at the top and isolated from each other. The inner chassis portion 11 has a drain outlet 111, which is connected to the first water tank 121. The first water tank 121 has a water outlet hole 1215. The drain valve 13 is located at the water outlet hole 1215 to open and close the water outlet hole 1215. The window air conditioner 100 includes a drainage path that is connected to the water outlet hole 1215 and the second water tank 122 respectively.

[0056] Combination Figures 2-6 The main unit 2 includes an indoor heat exchanger 21, an outdoor heat exchanger 22, and an outdoor fan 23. The indoor heat exchanger 21 is located above the inner chassis 11, and the outdoor heat exchanger 22 and the outdoor fan 23 are located above the outer chassis 12. The outdoor fan 23 includes a rotatable water-spraying ring 232. The rotation axis of the water-spraying ring 232 is horizontal and its bottom extends into the first water tank 121. At least a portion of the outdoor heat exchanger 22 is located above the second water tank 122, and a heating element 25 is provided at the second water tank 122.

[0057] In related technologies, window air conditioners collect condensate from the indoor heat exchanger during cooling operation and discharge it to the chassis of the outdoor unit. A water-scraping ring around the outdoor fan deflects the condensate onto the surface of the outdoor heat exchanger to aid heat dissipation and improve cooling capacity. However, during heating operation in winter, melted rainwater, snow, or defrost water from the outdoor heat exchanger accumulates in the chassis and freezes. This causes the water-scraping ring to collide with the ice, affecting the fan's operation and generating scraping noise. In severe cases, it can lead to the fan malfunctioning or being damaged.

[0058] In the technical solution of this application, by forming a first water tank 121 and a second water tank 122 on the outer chassis portion 12, both the first water tank 121 and the second water tank 122 being open at the top and isolated from each other, the outer chassis portion 12 is divided into two areas. The first water tank 121 can be used as a storage area for condensate during summer cooling operation, and the second water tank 122 can be used as a drainage area for rainwater, snow water, and defrost water during winter heating operation. The bottom of the water-beating ring 232 of the outdoor fan 23 is inserted into the first water tank 121. During summer cooling operation, the water outlet 1215 in the first water tank 121 is closed by the drain valve 13. Thus, the water-beating ring 232 can be used to drive or strike the condensate in the first water tank 121 to dissipate the condensate. Water is sprayed or splashed onto the surface of the outdoor heat exchanger 22 to assist in heat dissipation and improve the cooling capacity of the window air conditioner 100. When the air conditioner is in heating mode in winter, if the melted rainwater or defrost water on the outdoor heat exchanger 22 drips into the second water tank 122 and is quickly discharged, it will not enter the first water tank 121 and freeze, thus interfering with the rotation of the water-cooling ring 232. Even if some water accidentally enters the first water tank 121 during winter heating mode, the water outlet 1215 can be in the open state to quickly discharge the water that accidentally entered the first water tank 121. This reduces the risk of noise and damage caused by the water-cooling ring 232 colliding with ice due to ice formation in the first water tank 121, thereby extending the service life of the water-cooling ring 232 and enabling the outdoor fan 23 to work reliably.

[0059] Furthermore, a heating element 25 is provided at the second water tank 122. Even if melted rainwater or defrost water from the outdoor heat exchanger 22 drips into the second water tank 122 and freezes without being drained, the heating element 25 can quickly melt the ice and drain it, thus enabling timely and effective drainage of accumulated water. This reduces the possibility of water from the second water tank 122 entering the first water tank 121, thereby improving the reliability of equipment operation. During winter heating operation, frost will form on the surface of the outdoor heat exchanger 22. After frost formation, the outdoor heat exchanger 22... The reduced heat exchange capacity of the outdoor heat exchanger 22 leads to a decrease in the heating efficiency of the window air conditioner 100. A heating element 25 is located at the second water tank 122, and the outdoor heat exchanger 22 is positioned above the outer chassis 12. Therefore, the heating element 25 assists the defrosting mode of the window air conditioner 100 in accelerating the melting of frost on the outdoor heat exchanger 22, thereby reducing the defrosting mode operation time—that is, the time the user waits for the window air conditioner 100 to heat up—improving the heating response speed of the window air conditioner 100 and enhancing the user experience and comfort. The location of the heating element 25 is not limited; for example, it can be located above the chassis component 1 and inside the second water tank 122, or it can be located below the chassis component 1 and outside the second water tank 122.

[0060] The indoor heat exchanger 21 is located above the inner chassis 11, and the inner chassis 11 has a drain outlet 111 that is connected to the first water tank 121. This allows for the collection of condensate from the surface of the indoor heat exchanger 21 during summer cooling operation and guides the condensate into the first water tank 121 for collection and utilization. Specifically, during cooling operation, the surface temperature of the indoor heat exchanger 21 is lower than the dew point temperature of the indoor air, causing water vapor in the indoor air to condense and form condensate. Since the indoor heat exchanger 21 is located above the inner chassis 11, the condensate collects and slides down to the inner chassis 11, thus facilitating its collection and entry into the first water tank 121 through the drain outlet 111. This makes the collection of condensate more convenient and facilitates the storage and utilization of condensate in the first water tank 121.

[0061] In the embodiments of this application, a first water tank 121 and a second water tank 122 are formed on the outer chassis portion 12. The first water tank 121 and the second water tank 122 can be separated by setting a separator (such as a rib 153, a baffle, etc.) on the outer chassis portion 12, or a finished water tank box can be set on the outer chassis portion 12. The finished water tank box can be two separate water tank boxes or an integrated water tank box (such as the outdoor unit water receiving tray 15 below).

[0062] In embodiments of this application, the window air conditioner 100 includes drainage paths communicating with the water outlet 1215 and the second water tank 122, respectively. The "drainage path" refers to a combination of channels, holes, or spaces through which water flows from the first water tank 121 and the second water tank 122 to the outer chassis portion 12. The function of the drainage path is to guide and drain condensate or other liquids generated by the air conditioner. Therefore, the form of the drainage path is not limited; for example, it can be a drain hole or a water pumping pipe combined with a spray nozzle.

[0063] In some embodiments, combined with Figure 1 and Figure 7 The outer chassis portion 12 is located on one side of the inner chassis portion 11 in the first direction F1. The first water tank 121 includes a water guide section 1211 and a water storage section 1212. The water storage section 1212 is located on the side of the second water tank 122 away from the inner chassis portion 11 in the first direction F1. The water guide section 1211 is located on one side of the second water tank 122 in the second direction F2. The water guide section 1211 extends from the drain outlet 111 to the water storage section 1212 and is connected to one end of the water storage section 1212 in the second direction F2. The water outlet 1215 is located on the side of the water storage section 1212 away from the water guide section 1211 in the second direction F2. The second direction F2 is perpendicular to the first direction F1 and both are perpendicular to the vertical direction.

[0064] In the above technical solution, the first water tank 121 includes a water guiding channel section 1211 and a water storage channel section 1212. The water guiding channel section 1211 is located on one side of the second water tank 122 in the second direction F2, and the water storage channel section 1212 is located on the side of the second water tank 122 away from the inner chassis portion 11 in the first direction F1. Therefore, the water guiding channel section 1211 and the water storage channel section 1212 are positioned relatively close to the edge (i.e., near the edge). On the one hand, this allows for more space to be reserved for the installation of the second water tank 122, so that the second water tank 122 can better receive outdoor water. The defrost water on the heat exchanger 22 reduces the possibility of defrost water dripping randomly and speeds up the collection and discharge of defrost water. On the other hand, the water guide section 1211 and the water storage section 1212 are set relatively close to the side, which can reduce the intersection of the first water tank 121 and the outdoor heat exchanger 22 on the horizontal projection of the air conditioner, and reduce the possibility of defrost water falling into the first water tank 121. This reduces the risk of noise and damage caused by the impact of the water ring 232 due to ice formation in the first water tank 121 during winter heating operation, and extends the service life of the water ring 232.

[0065] Furthermore, in the above technical solution, the water storage tank section 1212 is positioned relatively close to the side and has a longer length in the second direction F2, which allows the contact length between the water-applying ring 232 and the water storage tank section 1212 to be longer. As a result, the water-applying ring 232 can drive or strike more condensate water, causing it to be thrown or splashed onto the outdoor heat exchanger 22, thereby improving the cooling capacity of the window air conditioner 100.

[0066] In some embodiments, combined with Figure 1 and Figure 2 The outdoor heat exchanger 22 includes a first heat exchange section 221 and a second heat exchange section 222. The first heat exchange section 221 is located above the second water tank 122 and is disposed between the outdoor fan 23 and the inner chassis section 11. (See figure) Figure 4 The second heat exchange section 222 is located above the water guide channel section 1211; back Figure 1 and Figure 2 The outer chassis section 12 also includes a water baffle 123, which is located above the water guide channel section 1211 and below the second heat exchange section 222.

[0067] In the above technical solution, the outdoor heat exchanger 22 is divided into a first heat exchange section 221 and a second heat exchange section 222, which are respectively arranged above the second water tank 122 and above the water guide section 1211. This can make more effective use of space and ensure that the air can fully exchange heat when it flows through the heat exchanger, which helps to improve the overall heat exchange efficiency and thus improve the cooling or heating performance of the air conditioner.

[0068] In the above technical solution, the water baffle 123 is positioned above the water guide channel section 1211 and below the second heat exchange section 222. During winter heating operation, it can prevent defrosting water droplets on the second heat exchange section 222 from falling into the water guide channel section 1211 and flowing into the water storage tank section 1212, where they freeze. This reduces the noise and damage risk caused by the impact of the water ring 232 due to ice formation in the first water tank 121 during winter heating operation, and extends the service life of the water ring 232. During summer cooling operation, it can also prevent dust, small stones and other particles on the second heat exchange section 222 from entering the water guide section 1211 and then the water storage section 1212. On the one hand, it can protect the water pumping ring 232 from colliding with hard particles when rotating to pump water, thus extending the service life of the water pumping ring 232. On the other hand, it also reduces the amount of fine particles such as dust being carried by the water pumping ring 232 and thrown onto the outdoor heat exchanger 22, thereby maintaining the proximity of the surface of the outdoor heat exchanger 22, reducing the thermal resistance of the heat exchanger, and improving the cooling or heating performance of the air conditioner.

[0069] In the embodiments of this application, the material of the water-blocking cover 123 is not limited, for example, it can be plastic, stainless steel, aluminum alloy, etc.; the way the water-blocking cover 123 is matched with the water-guiding channel section 1211 is not limited, for example, the water-blocking cover 123 can be matched with the water-guiding channel section 1211, or the water-blocking cover 123 can be larger than the water-guiding channel section 1211 and cover it.

[0070] In some embodiments, combined with Figure 1 and Figure 2 The end of the water storage tank section 1212 near the water guide tank section 1211 is the tank end 1214. The second heat exchange section 222 also extends above the tank end 1214. The water baffle cover 123 includes a first cover part 1231 and a second cover part 1232. The first cover part 1231 covers the water guide tank section 1211, and the second cover part 1232 is connected to the end of the first cover part 1231 and covers the tank end 1214.

[0071] In the above technical solution, combined with Figure 2 and Figure 7 The second heat exchange section 222 extends above the end of the channel 1214, thereby further utilizing the structural space and increasing the area of ​​the outdoor heat exchanger 22, thus improving the cooling or heating performance of the air conditioner. The water baffle 123 includes a first cover 1231 and a second cover 1232. The first cover 1231 covers the water guide channel section 1211, and the second cover 1232 is connected to the end of the first cover 1231 and covers the end of the channel 1214. This further prevents defrosting water droplets on the second heat exchange section 222 from falling into the water guide channel section 1211 and flowing into the water storage tank section 1212, where they freeze. It also further prevents dust, small stones, and other particles on the second heat exchange section 222 from entering the water guide channel section 1211 and then the water storage tank section 1212, thereby improving the operational reliability and cooling or heating performance of the air conditioner.

[0072] In some embodiments, combined with Figure 1 and Figure 7 The first water tank 121 also includes a drainage trough section 1213, which is connected to the end of the water storage tank section 1212 away from the water guide trough section 1211 in the second direction F2. The bottom wall of the drainage trough section 1213 is lower than the bottom wall of the water storage tank section 1212, and the water outlet 1215 penetrates the bottom wall of the drainage trough section 1213.

[0073] In the above technical solution, the bottom wall of the drainage trough section 1213 is lower than the bottom wall of the water storage trough section 1212, allowing condensate and other water to flow more smoothly from the water storage trough section 1212 to the drainage trough section 1213, and finally discharged through the outlet hole 1215. The drainage trough section 1213 is connected to the water storage trough section 1212 at the end away from the guide trough section 1211. This layout not only conforms to the natural law of water flow direction but also helps maintain the compactness and stability of the overall structure. At the same time, the setting of the drainage trough section 1213 also prevents condensate from flowing to other parts of the equipment, reducing the potential risk of damage. In addition, the setting of the drainage trough section 1213 makes cleaning and maintenance easier. Since condensate eventually accumulates in the drainage trough section 1213 and is discharged through the outlet hole 1215, the drainage trough section 1213 can be cleaned regularly to prevent blockage and scale buildup.

[0074] In some embodiments, see Figure 7 The water storage tank section 1212 is formed as a long strip-shaped trough extending along the second direction F2 in the length direction. The dimension L of the drainage trough section 1213 in the width direction of the water storage tank section 1212 is greater than the width H of the water storage tank section 1212. The bottom of the drainage valve 13 is installed in the drainage trough section 1213.

[0075] In the above technical solution, the dimension L of the drainage trough section 1213 in the width direction of the water storage trough section 1212 is greater than the width H of the water storage trough section 1212, thereby increasing the carrying capacity of the drainage trough section 1213. This allows the drainage trough section 1213 to more effectively receive and contain the condensate flowing down from the water storage trough section 1212, preventing condensate from accumulating at the connection between the water storage trough section 1212 and the drainage trough section 1213, thus improving drainage efficiency. At the same time, the greater dimension L of the drainage trough section 1213 in the width direction of the water storage trough section 1212 also provides more space for the installation of the drain valve 13, making its installation more convenient.

[0076] In some embodiments, see Figure 1 The water guiding channel section 1211 is formed as an elongated channel extending along the first direction F1 in the length direction, and the water storage channel section 1212 is formed as an elongated channel extending along the second direction F2 in the length direction, combined with Figure 4 and Figure 9 At least a portion of the bottom wall of the water guide trough section 1211 extends downward at an angle toward the water guide trough section 1211 in a first direction F1, and at least a portion of the bottom wall of the water storage trough section 1212 extends downward at an angle toward the water outlet 1215 in a second direction F2.

[0077] In the above technical solution, both the water guiding channel section 1211 and the water storage channel section 1212 are designed as elongated channels, extending along the first direction F1 and the second direction F2 respectively, which helps guide the water flow along a predetermined path. The inclined design of the bottom wall of the water guiding channel section 1211 allows the water to flow smoothly into the water storage channel section 1212, while the inclined design of the bottom wall of the water storage channel section 1212 helps accelerate the water flow towards the outlet hole 1215, thereby improving drainage efficiency. The inclined bottom wall design reduces the accumulation and sedimentation of water in the channel, helping to keep the channel clean and unobstructed. This reduces bacterial growth, reduces maintenance frequency, and extends the service life of the equipment.

[0078] In some embodiments, see Figure 8 The chassis component 1 includes a chassis 14 and an outdoor unit water receiving tray 15. The outdoor unit water receiving tray 15 is installed above the chassis 14. The first water tank 121 and the second water tank 122 are both formed on the outdoor unit water receiving tray 15, and the outdoor unit water receiving tray 15 includes a rib 153 for separating the first water tank 121 and the second water tank 122.

[0079] In the above technical solution, the chassis component 1 includes a chassis 14 and an outdoor unit water receiving tray 15. The outdoor unit water receiving tray 15 is installed on top of the chassis 14. Thus, the chassis component 1 is a combined component. The chassis 14 does not need to bear the function of the outdoor unit water receiving tray 15. The outdoor unit water receiving tray 15 has many protruding ribs 153 for separating the first water tank 121 and the second water tank 122, and its shape is complex. Therefore, the chassis component 1 being a combined component can facilitate the processing and manufacturing of the chassis 14 and improve production efficiency.

[0080] In the above technical solution, both the first water tank 121 and the second water tank 122 are formed on the outdoor unit's water receiving pan 15, and the outdoor unit's water receiving pan 15 includes a rib 153 for separating the first water tank 121 and the second water tank 122. Thus, the rib 153 isolates the first water tank 121 and the second water tank 122 from each other, achieving functional zoning. Specifically, the first water tank 121 is responsible for storing and utilizing condensate during summer cooling operation, while the second water tank 122 is responsible for collecting and draining rainwater, snowmelt, and defrost water during winter heating operation. This reduces the risk of noise and damage caused by the impact of the water ring 232 due to ice formation in the first water tank 121 during winter heating operation, extends the service life of the water ring 232, and improves the reliability of the window air conditioner 100.

[0081] In the embodiments of this application, the outdoor unit water receiving tray 15 includes a raised rib 153 for separating the first water tank 121 and the second water tank 122. Here, "separation" means that the raised rib 153 physically blocks the flow of water, preventing water from freely flowing from one water tank area to another. Of course, this application is not limited to the raised rib 153; it is understood that the function of the raised rib 153 is to divide the space on the outdoor unit water receiving tray 15 into two independent water tank areas. Therefore, any structure capable of achieving this function is included.

[0082] In some embodiments, see Figure 10 The drainage path includes a first drain hole 141 formed on the chassis 14, which is opposite to and directly below the outlet hole 1215. Thus, condensate can be discharged directly from the chassis 14 through the first drain hole 141 after passing through the outlet hole 1215, reducing detours and obstructions in the drainage path (such as passing through other pipe structures), thereby improving drainage efficiency. Furthermore, the fact that the first drain hole 141 is opposite to and directly below the outlet hole 1215 makes the drainage path more direct and compact, reducing additional drainage pipes and connecting parts, lowering the complexity of the overall structure, and helping to prevent condensate from accumulating or leaking on the chassis 14, thereby keeping the equipment dry and clean and reducing the possibility of bacterial growth and odor generation.

[0083] In some embodiments, combined with Figure 2 and Figure 8 The drainage path includes at least one second drain hole 142 formed on the chassis 14, and a water passage space is formed between the outdoor unit water receiving tray 15 and the chassis 14, connecting the second drain hole 142 and the second water tank 122.

[0084] In the above technical solution, by providing at least one second drain hole 142 on the chassis 14 and forming a water passage space between the chassis 14 and the outdoor unit water receiving tray 15, water in the second water tank 122 can flow through the water passage space to the second drain hole 142, allowing the water in the second water tank 122 to be discharged outside the chassis 14. This enhances drainage capacity and reduces the possibility of rainwater, snowmelt, and defrost water accumulating and overflowing the protruding ribs 153 used to separate the first water tank 121 and the second water tank 122, thus entering the first water tank 121. By designing a reasonable drainage path, including the position of the second drain hole 142 and the water passage space, the drainage path of rainwater, snowmelt, and defrost water can be shortened, reducing unnecessary turns and backflows, thereby enhancing drainage capacity.

[0085] In the embodiments of this application, the water passage space refers to the space formed between the water receiving tray and the chassis 14, which connects the second drain hole 142 and the second water tank 122. The water passage space ensures that water in the second water tank 122 can flow smoothly out of the chassis 14 without accumulating in the second water tank 122 or on the chassis 14. Therefore, the water passage space can be the gap between the outdoor unit water receiving tray 15 and the chassis 14, the outdoor unit water receiving tray 15 or the structure on the chassis 14, etc.

[0086] In some embodiments, see Figure 8 The bottom wall of the second water tank 122 extends to the first edge 151 of the outdoor unit water receiving tray 15, and the water in the second water tank 122 flows through the first edge 151 to the water passage space or the second drain hole 142.

[0087] In the above technical solution, since the bottom wall of the second water tank 122 extends directly to the first edge 151, the liquid does not need to pass through other drainage structures (such as setting drainage holes on the bottom wall of the second water tank 122) when it flows out, which reduces the possibility of liquid accumulation in the second water tank 122, optimizes the drainage path, and improves drainage efficiency.

[0088] In some embodiments, combined with Figure 5 and Figure 8 The bottom wall of the second water tank 122 includes a boss 1221, and a portion of the boss 1221 forms an opening area 1222 that extends vertically through it. The heating unit 25 is located above the boss 1221. The chassis 14 includes a mounting platform 143 that extends upward into the opening area 1222. The mounting bracket of the outdoor fan 23 is mounted on the mounting platform 143. The second water tank 122 is connected to the water passage space through the opening area 1222.

[0089] In the above technical solution, the bottom wall of the second water tank 122 includes a boss 1221, and the heating part 25 is located above the boss 1221, so that the heating part 25 is closer to the outdoor heat exchanger 22 installed thereon. Thus, the heating part 25 can better assist the defrosting mode of the window air conditioner 100 to accelerate the melting speed of the frost on the outdoor heat exchanger 22, thereby reducing the running time of the defrosting mode, that is, the time for the user to wait for the window air conditioner 100 to heat up, improving the heating response speed of the window air conditioner 100, and improving the user experience and comfort.

[0090] In the above technical solution, the boss 1221 has a vertically penetrating opening area 1222, and the chassis 14 includes a mounting platform 143 extending upward into the opening area 1222. Thus, the mounting platform 143 can be used to install the mounting bracket of the outdoor fan 23, providing stable support for the mounting bracket. The mounting bracket of the outdoor fan 23 is mounted on the chassis 14 rather than on the boss 1221, which facilitates the functional separation of the chassis 14 and the outdoor unit water receiving tray 15, making the processing and manufacturing of the chassis 14 and the outdoor unit water receiving tray 15 easier and improving production efficiency. The second water tank 122 is connected to the water passage space through the opening area 1222, optimizing the drainage path of the second water tank 122, reducing the possibility of liquid accumulation in the second water tank 122, and improving drainage efficiency.

[0091] In some embodiments, see Figure 8 The bottom wall of the second water tank 122 also includes a recessed channel 1223, which is lower than the boss 1221. The recessed channel 1223 extends to the second edge 152 of the outdoor unit's water receiving tray 15, and the water flows through the second edge 152 to the water passage space or the second drain hole 142. The recessed channel 1223, being lower than the boss 1221, forms a low-lying area, which helps guide the water flow along the path of the recessed channel 1223 and discharge through the second edge 152, thereby optimizing the drainage path of the second water tank 122, reducing the possibility of liquid accumulation in the second water tank 122, and improving drainage efficiency. In addition, the structure of the recessed channel 1223 also enhances the structural strength of the bottom wall of the second water tank 122, and by connecting with the second edge 152 of the outdoor unit's water receiving tray 15, it increases the stability of the entire drainage system. Furthermore, the structure of the recessed channel 1223 makes it easy to clean the second water tank 122 and its drainage path when cleaning and maintaining the equipment, reducing maintenance difficulty and cost.

[0092] In some embodiments, see Figure 8 The chassis 14 is made of metal. As a result, the externally located chassis 14 has good structural strength and service life.

[0093] In some embodiments, see Figure 8The outdoor unit's water receiving tray 15 is an injection-molded part. Injection molding is a highly efficient, mass-production method suitable for producing parts with complex shapes and precise dimensions. By designing the outdoor unit's water receiving tray 15 as an injection-molded part, production efficiency can be significantly improved, manufacturing costs reduced, and injection-molded parts typically have high dimensional accuracy and smooth surfaces, meeting the stringent requirements of equipment regarding the shape and dimensions of the outdoor unit's water receiving tray 15. This also reduces the processing difficulty of the chassis 14, especially when the chassis 14 is a metal part and the water tank has a complex structure. It eliminates the need for complex design and processing of the chassis 14, reducing its processing difficulty and allowing for better compatibility between the outdoor unit's water receiving tray 15 and the chassis 14. This helps reduce drainage difficulties caused by incompatibility between the outdoor unit's water receiving tray 15 and the chassis 14.

[0094] Of course, if the structure is relatively simple and the structural strength can meet the requirements, only one of the outdoor unit water receiving tray 15 and the chassis 14 can be installed.

[0095] In some embodiments, see Figure 1 Drain valve 13 is a temperature-controlled drain valve 13.

[0096] In the above technical solution, the temperature-controlled drain valve 13 can automatically open or close according to the temperature, realizing intelligent drainage control and improving the automation level of the equipment. For example, in low-temperature winter environments, the temperature-controlled drain valve 13 can automatically open, thereby preventing accidental water from accumulating and freezing in the water storage tank section 1212, reducing the noise and damage risk caused by the impact of the water-applying ring 232 due to ice formation in the water storage tank section 1212, and extending the service life of the water-applying ring 232.

[0097] In some embodiments, see Figure 8 The main unit 2 includes a compressor 26, and the heating unit 25 is configured as a bypass pipe connected to the compressor 26.

[0098] In the above technical solution, the heating unit 25 is constructed as a bypass pipe connected to the compressor 26. This allows heating to be achieved directly using the refrigerant within the bypass pipe, eliminating the need for electric auxiliary heating and reducing the electrical complexity of the equipment. Furthermore, since the compressor 26 is spatially close to the heating unit 25, using the bypass pipe to achieve the heating function of the heating unit 25 requires minimal wiring, and the structure is simple and easy to implement. Of course, this application is not limited to this; for example, an electric heating device can also be used as the heating unit 25.

[0099] In some embodiments, see Figure 1 The outdoor fan 23 includes an axial flow impeller 231, the axis of which is horizontally positioned, and the water jet ring 232 is integrated with the axial flow impeller 231.

[0100] In the above technical solution, the axial flow impeller 231 and the water spray ring 232 are integrated. The water spray ring 232 can rotate together with the axial flow impeller 231, without the need to set a separate rotation drive device for the water spray ring 232, which reduces the number of parts and makes the structure of the window air conditioner 100 more compact.

[0101] In some embodiments, at least two of the following conditions can be met simultaneously: "the outdoor fan 23 includes an axial flow impeller 231, the axis of the axial flow impeller 231 is horizontally positioned, and the water jet ring 232 is integrally formed with the axial flow impeller 231"; "the main unit 2 includes a compressor 26, and the heating unit 25 is configured as a bypass pipe connected to the compressor 26"; and "the drain valve 13 is a temperature-controlled drain valve 13". These conditions will not be elaborated here.

[0102] Combination Figures 3 to 1 The window air conditioner 100 is divided into two parts: an indoor unit and an outdoor unit, which are integrated on the chassis component 1. During cooling, the indoor heat exchanger 21 drips condensate downwards, which is collected by the inner chassis 11 and then discharged to the outer chassis 12 through the drain outlet 111. The outer chassis 12 has a first water tank 121 and a second water tank 122. The first water tank 121 is divided into a water guiding section 1211, a water storage section 1212, and a drain section 1213. The end of the water storage section 1212 near the water guiding section is the end of the tank 1214. The water baffle 123 includes a first cover portion 1231 and a second cover portion 1232. The first cover portion 1231 covers the water guiding section 1211, and the second cover portion 1232 is connected to the end of the first cover portion 1231 and covers the end of the tank 1214. A heating bypass pipe is arranged in parallel on the second direction F2 of the baffle cover 123. The bypass pipe is set on the boss 1221 of the second water tank 122. An outdoor heat exchanger 22 is set on the upper part of the baffle cover 123 and the bypass pipe. The bypass pipe is connected to the entire refrigeration compressor 26 piping system and can bypass the refrigerant when heating, thereby removing the ice dripping from the outdoor heat exchanger 22 onto the second water tank 122.

[0103] refer to Figures 2 to 10 The outdoor heat exchanger 22 is L-shaped or U-shaped, surrounding the outdoor fan 23 in the middle. The axial flow impeller 231 of the outdoor fan 23 is provided with a water-spraying ring 232, so that when the axial flow impeller rotates, the water-spraying ring 232 around its outer edge can stick the condensate in the water storage tank section 1212 of the first water tank 121 to the water-spraying ring 232 and splash the water onto the side of the outdoor heat exchanger 22.

[0104] The first water tank 121 is divided into a water guiding section 1211, a water storage section 1212, and a drainage section 1213. The three sections are connected end to end and have a certain slope. The water guiding section 1211 is connected to the water storage section 1212 below the water ring 232. The water storage section 1212 is then connected to the drainage section 1213, which has a lower bottom wall. A water outlet 1215 is provided inside the drainage section 1213, which is connected to the first drain hole 141 on the lower chassis 14. A temperature-controlled drain valve 13 is provided above the water outlet 1215.

[0105] In addition, the chassis 14 has at least one second drain hole 142. The chassis 14 is provided with multiple second drain holes 142 so that the defrost water of the outdoor heat exchanger 22 can be discharged to the outside of the chassis 14 in a timely manner when the window air conditioner 100 is in heating mode in winter, and to ensure that water does not accumulate in the outdoor unit during rain and snow, thereby ensuring that the inside of the chassis 14 does not freeze and ensuring the overall heating performance.

[0106] The following describes the operation of window air conditioner 100:

[0107] When the outdoor ambient temperature is higher than the set temperature T, the temperature-controlled drain valve 13 is in the closed state of the lower water outlet 1215. At this time, the drain trough section 1213 cannot drain water through the bottom water outlet 1215 to the outdoor unit water receiving pan 15 and the outside of the chassis 14 to store water. The water storage causes the liquid level of the water storage trough section 1212 connected to the drain trough section 1213 to rise together. At this time, a water-spraying ring 232 is set on the upper part of the water storage trough section 1212 so that when the user turns on the cooling mode, the outdoor unit can use the stored condensate to splash water onto the outdoor heat exchanger 22 on the side to achieve auxiliary heat dissipation and improve the cooling capacity and energy efficiency.

[0108] When the outdoor ambient temperature is lower than the set temperature T, the temperature-controlled drain valve 13 is in the open state of the lower water outlet 1215. At this time, the drain trough section 1213 drains water through the bottom water outlet 1215 to the outside of the outdoor unit water receiving pan 15 and the chassis 14, so that the water receiving pan 15 of the outdoor unit will not accumulate water. The water-spraying ring 232 set on the upper part of the water storage trough section 1212 will not come into contact with condensate or any external water source (such as rain or snow water falling in through the air outlet grille of the outdoor fan 23 from the side of the water storage trough section 1212). This allows the outdoor unit to perform defrosting of the outdoor heat exchanger 22 and de-icing of the chassis 14 normally when the user turns on the heating mode, and ensures that water will not accumulate inside the outdoor unit water receiving pan 15, and that the water receiving pan 15 will not freeze due to the low outdoor ambient temperature. This also prevents the axial fan wheel 231 from freezing or the water-spraying ring 232 from hitting the ice layer inside the water storage trough section 1212.

[0109] Therefore, during the high-temperature cooling operation in summer, the condensate stored in the water storage section 1212 of the first water tank 121 is efficiently utilized by the water pumping ring 232. In winter, when the whole unit is heating at ultra-low temperatures, it can ensure that defrosting water dripping from the outdoor heat exchanger 22 and rain and snow water entering from the outside rain and snow weather will not enter the first water tank 121, thus preventing the water storage section 1212 from freezing and threatening the rotation of the axial flow fan 231.

[0110] This technical solution has the following beneficial effects:

[0111] 1. The first water tank 121 section 1212 on the outdoor unit water receiving pan 15 stores condensate, and the water ring 232 splashes water to the outdoor heat exchanger 22 to assist its heat dissipation and improve its cooling capacity and energy efficiency.

[0112] 2. A bypass pipe is installed on the boss 1221 of the second water tank 122 to assist the top outdoor heat exchanger 22 in defrosting and prevent ice from forming in the second water tank 122. It also helps to quickly discharge the defrost into the second water tank 122. Combined with multiple second drain holes 142 on the chassis 14, the defrost water and rainwater are quickly discharged from the chassis 14, preventing water from freezing in the water storage tank section 1212 of the first water tank 121 and colliding with the water ring 232, thus ensuring the safe operation of the whole machine.

[0113] 3. The water baffle 123 isolates the drainage path of the first water tank 121 from the outdoor heat exchanger 22, preventing defrosting water from the outdoor heat exchanger 22 from entering the water storage tank section 1212.
