[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0034] The utility model provides a window air conditioner, which aims to solve the problem of insufficient heat dissipation capacity of power devices in window air conditioners under the existing technology. Figures 1 to 10The window air conditioner of the present invention includes: a chassis 1, an evaporator 3, an electrical box 2, a water receiving tray 11 and a water storage tank 12. The evaporator 3 and the water storage tank 12 are arranged on the chassis 1, and the water receiving tray 11 is arranged below the evaporator 3 to receive condensed water. The water receiving tray 11 is connected to the water storage tank 12; wherein, the electrical box 2 is arranged in the water storage tank 12. During the operation of the existing window air conditioner, especially in the cooling mode, the power components 24 in the electrical box 2 are easily heated due to the heat generated during operation, thereby affecting the overall performance and service life of the air conditioner. Therefore, a new design is urgently needed to improve the heat dissipation effect and ensure the reliable operation of the equipment. The window air conditioner of the present invention can effectively reduce the temperature rise of the power components 24 in the electrical box 2 and extend its service life by optimizing the structural design. The window air conditioner's chassis 1 houses an evaporator 3 and a water tank 12. Below the evaporator 3 is a water pan 11, connected to the water pan 11 for fluid circulation. The water tank 12 also houses an electrical box 2. The chassis 1 serves as the supporting structure for the entire air conditioner. The evaporator 3 performs its cooling function, while the electrical box 2 controls and manages the air conditioner's electrical components. During cooling operation, the surface temperature of the evaporator 3 falls below the dew point of the indoor air, causing condensation to form on the surface of the evaporator 3. This condensation slides down the fins of the evaporator 3 and into the water pan 11, where it accumulates. The water tank 12 is connected to the water pan 11. Due to the window air conditioner's mounting configuration, the front is higher and the back is lower, at an angle of approximately 3 to 5 degrees. This allows condensation to flow from the water pan 11 into the water tank 12, which then stores the collected condensation. The electrical box 2 is arranged in the water storage tank 12, and the bottom of the electrical box 2 is immersed in condensed water. The low temperature characteristic of the condensed water is utilized to effectively cool the electrical box 2, thereby improving the heat dissipation efficiency.

[0035] Compared with the window air conditioner under the prior art, the window air conditioner of the present invention collects and drains the low-temperature condensed water dripping from the surface of the evaporator 3 to the water storage tank 12 through the water receiving tray 11, so that the electrical box 2 is immersed in the condensed water in the water storage tank 12, thereby reusing the condensed water to reduce the temperature of the electrical box 2 and thus cool and dissipate the power devices contained therein, thereby improving the heat dissipation capacity of the power devices in the window air conditioner.

[0036] In one embodiment, referring to 1 to Figure 3The water receiving tray 11 is provided with a condensed water receiving portion 111 and a flow guide portion 112. The condensed water receiving portion 111 is provided below the evaporator 3, and the flow guide portion 112 connects the condensed water receiving portion 111 and the water storage tank 12. The water receiving tank is provided with a condensed water receiving portion 111 and a flow guide portion 112. The condensed water receiving portion 111 is provided below the evaporator 3, and is used to centrally receive the condensed water flowing down from the surface of the evaporator 3. The flow guide portion 112 connects the condensed water receiving portion 111 and the water storage tank 12 to ensure that the condensed water can flow smoothly into the water storage tank 12. In this embodiment, by arranging the partition design of the condensed water receiving portion 111 and the flow guide portion 112 in the water receiving tank, the collection and diversion efficiency of the condensed water is further improved, which not only optimizes the management of the condensed water, but also effectively reduces the humidity inside the air conditioner, and improves the cooling effect and operation stability of the air conditioner. At the same time, partitioning the water tray 11 into the condensed water receiving portion 111 and the guide portion 112 also helps reduce mold or odor problems caused by condensed water retention, thereby improving the user experience.

[0037] In one embodiment, referring to Figures 1 to 3 , the bottom surface of the guide portion 112 is inclined from the side connected to the condensate receiving portion 111 to the side connected to the water storage tank 12. The bottom surface of the guide portion 112 is inclined from the side connected to the condensate receiving portion 111 to the side connected to the water storage tank 12. This inclined design allows the condensate to flow smoothly under the action of gravity, reducing the possibility of water stagnation. The inclination angle of the guide portion 112 can be designed according to actual needs, and is usually designed to be an inclination angle of 5-15 degrees to facilitate the rapid drainage of condensate. In the actual production process, the chassis 1 is usually a plastic part, and the condensate receiving portion 111 and the guide portion 112 divided by the water receiving tray 11 thereon can be formed by a mold surface during the thermoplastic molding process of the water receiving tank, and the angles are rounded to make the flow path through which the condensate flows as smooth and unobstructed as possible, thereby improving the flow efficiency of the condensate flowing to the water storage tank 12. In this embodiment, the inclined design of the bottom surface of the guide portion 112 significantly improves the flow efficiency of the condensed water, allowing the condensed water to flow into the water storage tank 12 more quickly and smoothly, preventing the condensed water from being retained in the water receiving tank, thereby reducing the mold and odor problems that may be caused by water accumulation.

[0038] In one embodiment, referring to Figures 8 to 10The electrical box 2 includes a waterproof bottom shell 21, which is provided with a power device accommodating cavity opening upward, and the waterproof bottom shell 21 is arranged in the water storage tank 12. The electrical box 2 includes a waterproof bottom shell 21, which is provided with a power device accommodating cavity opening upward, for safely accommodating power devices, and the waterproof bottom shell 21 is arranged in the water storage tank 12 to protect the power devices from condensation or other liquids. The material of the waterproof bottom shell 21 is selected from plastic or metal materials with good waterproof performance to ensure that it is not affected by moisture during long-term use. It is preferred to use a high thermal conductivity material such as aluminum alloy or copper to manufacture the waterproof bottom shell 21 to improve the heat exchange efficiency. In this embodiment, a waterproof bottom shell 21 is provided in the window air conditioner to ensure the safety and reliability of the power device in a humid environment and prevent short circuit or damage caused by the accumulation of condensation water. In addition, this design not only improves electrical safety, but also enhances the overall durability of the air conditioner and reduces maintenance costs.

[0039] Furthermore, the size of the waterproof bottom shell 21 matches the internal space of the water tank 12, ensuring good installation stability while not affecting the normal drainage function of the water tank 12.

[0040] Furthermore, the outer surface portion of the waterproof bottom shell 21 that contacts the condensed water is wavy or has other high surface area structures to increase the contact area of ​​the condensed water.

[0041] In one embodiment, referring to Figures 1 to 5 , a supporting protrusion is also provided between the bottom surface of the water tank 12 and the waterproof bottom shell 21. A supporting protrusion is provided between the bottom surface of the water tank 12 and the waterproof bottom shell 21. The supporting protrusion is used to prevent the waterproof bottom shell 21 from directly contacting the ground of the water tank 12, thereby leaving a gap between the two for condensate to pass through, thereby further improving the heat dissipation efficiency, and also enhancing the stability of the waterproof bottom shell 21, ensuring its fixation and reliability in the water tank 12. In actual use, the supporting protrusion can be designed as a plurality of small protrusions, evenly distributed on the bottom surface of the water tank 12, to provide uniform supporting force. In order to reduce costs and improve production efficiency, the supporting protrusion can be manufactured integrally with the water tank 12 by injection molding to ensure its strength and durability. In actual use, it has been found that using support protrusions with curved side surfaces, such as cylindrical or conical shapes, can ensure more even distribution of condensed water, avoid the formation of dead water areas, and thus improve the flow efficiency of condensed liquid within the water storage tank 12. This not only improves heat dissipation efficiency but also prevents mold growth within the water storage tank 12. In this embodiment, by providing support protrusions between the water storage tank bottom surface 121 and the waterproof bottom case 21, the heat dissipation efficiency and stability of the waterproof bottom case 21 are further improved, enhancing the ability to dissipate heat from the components within the electrical box 2 while effectively preventing the bottom case 21 from tilting or becoming unstable due to condensed water.

[0042] Further, refer to Figures 1 to 5 , the supporting protrusion is made of elastic material. Since other air-conditioning working components are also provided on the chassis 1, such as a compressor, these power components 24 will generate mechanical vibrations when the air-conditioning is working, especially the compressor. The vibration of the compressor drives other components on the chassis 1 to vibrate, including the electrical box 2. If the supporting protrusion is set to an elastic material, the vibration amplitude of the electrical box 2 and the power components 24 inside the electrical box 2 can be effectively avoided, reliability can be improved, and circuit failures caused by vibration aging can be reduced. The elastic material can be made of silicone, rubber or other synthetic materials with excellent elasticity. These materials not only have good deformation ability, but also can resist the erosion of moisture and chemicals. In this embodiment, by adopting a supporting protrusion made of elastic material, the vibration resistance and stability of the window air conditioner are significantly improved, and the vibration generated during the operation of the equipment can be effectively alleviated to prevent damage to electrical components.

[0043] In one embodiment, referring to Figure 8The electrical box 2 also includes a top shell 22, which covers the top of the waterproof bottom shell 21, and a heat dissipation grid 223 is provided on the top shell 22. The electrical box 2 also includes a top shell 22, which covers the top of the waterproof bottom shell 21, so that the electrical box 2 is closed. A heat dissipation grid 223 is provided on the top shell 22 to improve the heat dissipation efficiency of the power device. The material of the top shell 22 should be a metal material with good thermal conductivity, such as aluminum alloy or copper, to promote effective heat dissipation. In the actual assembly and installation process, the electrical box 2 is usually installed on the middle partition of the window air conditioner. Usually, there is a certain gap between the electrical box 2 and the middle partition, which allows airflow to pass through the front and back of the electrical box 2. The airflow completes gas exchange from the heat dissipation grid 223 to achieve heat dissipation of the power components 24 in the electrical box 2. The top shell 22 is composed of a front shell 221 and a rear shell 222. This design is for easy disassembly to prevent the integrated top shell 22 from getting stuck with the bottom shell 21. The front shell 221 is provided with holes, which are covered with a heat dissipation grid 223. The front shell 221 is also connected to the mounting plate 23. In order to assist the power components 24 in dissipating heat, the power components 24 are also provided with heat sinks 25, which are arranged close to the heat dissipation grid 223. The heat dissipation grid 223 must ensure the strength of the structure and the heat dissipation effect. The aperture and arrangement can be adjusted according to the heat dissipation requirements to achieve optimal air circulation. A sealing ring is provided between the top shell 22 and the bottom shell 21. While ensuring waterproof performance, the sealing ring also reduces the impact of the external environment on the power components. The top shell 22 and the waterproof bottom shell 21 are detachable structures to facilitate maintenance personnel to inspect and replace the internal power components 24. In this embodiment, the addition of a top case 22 and heat sink grille 223 to the power device box significantly enhances the heat dissipation capability of the power device, helping to reduce operating temperatures and extend the life of the device. The design of the top case 22 not only enhances the protection of the power device but also effectively prevents the intrusion of foreign matter, further improving the overall safety and reliability of the air conditioner.

[0044] In one embodiment, referring to Figures 1 to 4 、 Figures 6 and 7The chassis 1 is also provided with a drainage trough 13, which is connected to the water storage tank 12. The drainage trough 13 is used to connect to the drain outlet to discharge the condensed water. The chassis 1 is also provided with a drainage trough 13, which is connected to the water storage tank 12. The drainage trough 13 is used to connect to the drain outlet to effectively drain the condensed water. The drainage trough 13 should be designed to be concave downward from the chassis 1, with an appropriate depth and width to ensure that it can accommodate the condensed water and guide it to the drain outlet. The bottom of the drainage trough 13 has an appropriate inclination to promote the natural flow of condensed water and avoid water retention. The drainage trough 13 should be made of corrosion-resistant materials to ensure that it is not easily damaged during long-term use and maintain good drainage performance. The connection between the drainage trough 13 and the water storage tank 12 should ensure sealing to prevent condensed water leakage, and it is also easy to maintain and clean. In this embodiment, the drainage trough 13 can effectively reduce the accumulation of condensed water and prevent equipment damage and environmental pollution caused by water overflow.

[0045] Further, refer to Figures 1 to 4 、 Figures 6 and 7 The bottom surface of the drain trough 13 is lower than the bottom surface of the water receiving tray 11. The bottom surface of the drain trough 13 is lower than the bottom surface of the water receiving tray 11, so that the drain trough 13 can more effectively collect and guide the condensed water in the water storage tank 12 to flow to the drain outlet, ensuring that the condensed water will not be retained inside, thereby preventing water accumulation and possible overflow problems.

[0046] In one embodiment, referring to Figure 4 The window air conditioner of the present invention also includes an insulation tray 4, which covers the bottom surface of the water receiving tray 11. In actual use, it is found that when the air conditioner is working, since the temperature of the area between the evaporator 3 and the water receiving tray 11 is relatively low, when the ambient temperature is high and the humidity is high, condensation or even frost will appear under the chassis 1 due to the temperature difference, and eventually condensation water will fall, which will affect the safety of the equipment and reduce the user experience. For this reason, a heat insulation layer is provided on the water receiving tray 11 to prevent this from happening. The insulation tray 4 is made of a material with good heat insulation properties, such as polyurethane foam, polypropylene or other heat insulation composite materials, to effectively prevent heat exchange between condensed water and the external environment. In this embodiment, by adding an insulation tray 4 to the bottom surface of the water receiving tray 11, frost and condensation under the chassis 1 due to temperature difference can be prevented, thereby enhancing the stability and reliability of the equipment and improving the user experience.

[0047] The window air conditioner of the present invention also includes: a compressor responsible for compressing and circulating the refrigerant, converting the high-temperature, high-pressure refrigerant into a liquid state; a condenser that releases heat to the external environment through a heat dissipation process; an air circulation fan for air circulation; a filter for filtering dust and impurities from the air; a control panel for providing a user interface; a temperature sensor for monitoring the indoor temperature and providing feedback to the control system for automatic temperature control; a power module for providing power to the air conditioner; a drain pump for actively draining condensed water and enhancing drainage; thermal insulation for thermal insulation and protecting internal components to reduce energy loss; a housing for protecting internal components and providing structural support; connecting pipes for connecting the various components to form a complete refrigeration cycle and drainage system; and safety devices for ensuring safe use of the device. By combining these components, the window air conditioner can effectively cool, improve air quality, and ensure a safe user experience.

[0048] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention.
