[0020] Compared with the prior art, the above technical solutions provided by the embodiments of the present application have the following advantages:

[0021] The window type air conditioner provided by the embodiment of the application has the evaporator fixedly installed in the first accommodating cavity of the cabinet and the condenser fixedly installed in the second accommodating cavity of the cabinet. Since the first accommodating cavity and the second accommodating cavity are arranged in a staggered manner in the vertical direction, the evaporator and the condenser are arranged in a staggered manner in the vertical direction after the window type air conditioner is installed, that is, the evaporator is located in the upper space of the window type air conditioner and the condenser is located in the lower space of the window type air conditioner (which is the lowest position of the window type air conditioner). During the working process of the window type air conditioner, the evaporator causes the environment in the first accommodating cavity to have a relatively low temperature, so that the inner wall of the cabinet and the outer surface of the evaporator refrigerant pipeline condense condensate water due to the relatively low temperature of the environment. The condensate water flows downward along the outer surface of the cabinet under the action of its own gravity and converges in the first accommodating cavity. Since the first drainage channel is arranged in a slanting manner relative to the horizontal plane, the first drainage channel drains the condensate water in the first accommodating cavity from the high end of the first drainage channel to the low end of the first drainage channel. Then, the condensate water flows into the condenser of the second accommodating cavity under the action of its own gravity, so that the condenser exchanges heat with the condensate water. Since the evaporator and the condenser are arranged in a staggered manner in the vertical direction, the height difference between the two can be used to drain the condensate water to the top of the condenser through the first drainage channel. The condensate water naturally slides down under the action of its own gravity or under the auxiliary action of external wind force, and then flows along the outer surface of the condenser, thereby increasing the contact area of the condensate water and the condenser and improving the effective utilization rate of the condensate water, so as to improve the heat exchange efficiency of the condenser and the overall energy efficiency of the window type air conditioner.

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be described clearly and completely 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, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative effort fall within the scope of protection of the present application.

[0036] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplifying the present disclosure, some of the descriptions of particular examples are described in the following. Of course, they are only examples, and the purpose is not to limit the present application. In addition, reference numerals and / or letters can be repeated in different examples in the present application. Such repetition is for the purpose of simplification and clarity, and does not in itself indicate a relationship between the various embodiments and / or arrangements being discussed.

[0037] For the purpose of description, spatial relative terms can be used in the text to describe the relative positional relationship or movement of one element or feature with respect to another element or feature as shown in the figure, such as "internal", "external", "inner side", "outer side", "under", "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 is flipped over or the posture is changed or the movement state is changed, the directional indications will also change accordingly, for example: the element described as "under" or "below" other elements or features will be oriented as "above" or "above" other elements or features. Therefore, the example term "below" can include both the upper and lower positions. The device can be additionally oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the text are interpreted accordingly.

[0038] In the related art, due to the low temperature of the evaporator surface, low-temperature condensate water is generated when heat exchange with indoor air, and the condensate water flows to the outdoor side through the water pan and the bottom plate. Some window air conditioners will immerse the U-shaped tube at the bottom of the condenser in the condensate water to achieve the purpose of utilizing the cold energy of the condensate water, but the utilization rate of the condensate water is still low in general. The window air conditioner disclosed in CN220793295U draws the condensate water to the water hitting ring of the outdoor centrifugal fan through a water pump, and hits the condensate water on the condenser, but the newly added water pump consumes more power, and the energy saving effect will be discounted; CN105444283A discloses an auxiliary condenser, which is placed above the outdoor axial centrifugal fan, increasing the efficiency of the axial centrifugal fan hitting water, but the auxiliary condenser of this structure has a tilt angle between the main condenser, which has problems of difficult installation and excessive stress at the connection with the main condenser. In summary, the existing window air conditioner has the technical problem of low utilization rate of condensate water, resulting in low heat exchange efficiency of the condenser, affecting 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 existing window air conditioners is low, resulting in too low heat exchange efficiency of the condenser, and 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 force, 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 Figures 1 to 2 As shown, the present application provides a window air conditioner 100, which 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, and 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, which is arranged on the housing 1, and 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, specifically, 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 as a whole is an "L"-shaped structure. 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, as shown in FIG. 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] In the working process of the window air conditioner 100, the evaporator 2 causes the ambient temperature in the first accommodating cavity 11 to be low, so that the inner wall of the cabinet 1 and the outer surface of the refrigerant pipeline of the evaporator 2 condense condensed water due to the low ambient temperature. The condensed water flows downward along the outer surface of the cabinet 1 under the action of its own gravity and converges in the first accommodating cavity 11. Since the first drainage channel 41 is arranged obliquely relative to the horizontal plane, the first drainage channel 41 drains the condensed water in the first accommodating cavity 11 from the high end of the first drainage channel 41 to the low end of the first drainage channel 41. Then, the condensed water flows into the condenser 3 in the second accommodating cavity 12 under the action of its own gravity, so that the condenser 3 exchanges heat with the condensed water. Since the evaporator 2 and the condenser 3 are arranged in a staggered manner in the vertical direction, the height difference between the two can be used to drain the condensed water to the top of the condenser 3 through the first drainage channel 41. 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, increases the contact area of the condensed water and the condenser 3, improves the effective utilization rate of the condensed water, and thus improves the heat exchange efficiency of the condenser 3 and the overall energy efficiency of the window air conditioner 100.

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

[0044] In a preferred embodiment, as shown in Figure 1 The condenser 3 is arranged horizontally at the second end of the second accommodating cavity 12, and the evaporator 2 is arranged vertically at the end of the first accommodating cavity 11 away from the second accommodating cavity 12. It can be understood that placing the condenser 3 horizontally upside down at the bottom of the second accommodating cavity 12 can increase the contact area of the condenser 3 and the condensed water, facilitate the installation of the fan assembly 5, effectively utilize the vertical space of the second accommodating cavity 12, shorten the size of the second accommodating cavity 12 in the width direction, which is the X direction shown in the figure, and make the overall size of the window air conditioner 100 smaller. The evaporator 2 is arranged vertically in the first accommodating cavity 11. Since the evaporator 2 needs to be installed on the indoor side to cool the indoor room by using the cold energy of the evaporator 2, this design facilitates the installation of the window air conditioner 100 by workers.

[0045] The window type air conditioner 100 has a wide range of application scenarios in modern home environments. In small apartments, space is extremely limited, and every inch of space is precious. This compactly designed window type air conditioner 100 can be easily installed on the window of a bedroom or living room, without occupying too much indoor floor space, and can efficiently regulate indoor temperature to create a comfortable living environment for the occupants. In some old residential buildings, due to the limitations of the building structure, there may be no dedicated air conditioner outdoor unit site, and the window type air conditioner 100 becomes an excellent choice. Its integrated design, by reasonably utilizing the vertical space to reduce the overall size, can better adapt to the size specifications of the window, making installation convenient and not affecting the appearance of the building. In small offices or shops, the window type air conditioner 100 can also play an important role. It can quickly cool and heat, maintaining a suitable temperature in a limited space, providing a comfortable working environment for staff or a pleasant shopping atmosphere for customers, and its smaller overall size will not cause too much interference to the indoor layout and display, making it convenient for businesses to flexibly place goods display stands 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 type air conditioner 100, and can effectively reduce the size of the window type air conditioner 100 in terms of overall size, so that the window type air conditioner 100 can occupy a smaller space in the installation and use scenario, more in line with the demand for miniaturization and refinement of electrical products in modern homes, and also helps to reduce production costs and space occupation during transportation, and other aspects of efficiency improvement.

[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, low-pressure gaseous refrigerant generated by the evaporator 2 is compressed into a high-temperature, 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 through 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 more smoothly along the outer surface of the condenser 3, 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 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 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 condenser 3 can also be provided with the second end of the second accommodating chamber 12 tilted relative to the horizontal direction. On the one hand, the condensed water can slide down along the outer surface of the condenser 3 under the action of its own gravity. 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 upper end of the first drainage channel 41 is provided with a condensed water inlet 411, which is connected to the first accommodating chamber 11; the lower end of the first drainage channel 41 is provided with a condensed water outlet 412, which extends in a direction close to the condenser 3 and is connected to the second accommodating chamber 12. It can be understood that because 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 condenses on the inner wall of the housing 1 and the outer surface of the refrigerant pipe of the evaporator 2 due to the lower ambient temperature. Under the action of its own gravity, the condensed water flows from top to bottom along the outer surface of the housing 1 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. Then, under the action of its own gravity, this part of the condensed water flows into the condenser 3, so that the condenser 3 and the condensed water exchange heat.

[0049] Optionally, the condensate water inlet 411 is connected with the first accommodating cavity 11, and is specifically arranged as penetrating the box body 1 and being in communication with the first accommodating cavity 11; the condensate water outlet 412 is connected with the second accommodating cavity 12, and is specifically arranged as penetrating the box body 1 and being in communication with the second accommodating cavity 12.

[0050] In actual design and application process, the shape of the condensate water inlet 411 and the condensate water outlet 412 has multiple choices. The condensate water inlet 411 and the condensate water outlet 412 can be arranged as a circular shape, the circular structure can make the condensate water flow more smoothly when flowing in or out, reduce the water flow resistance, and it is relatively simple in processing and manufacturing, which can be realized by conventional pipe cutting, bending and welding process; it can also be an elliptical shape, the elliptical shape has unique advantages under certain specific space layout or fluid dynamics requirements, the elliptical condensate water inlet 411 and the condensate water outlet 412 can better adapt to the overall structure design, and also show different characteristics from the circular shape in water flow stability; it can also be arranged as a square shape, the square design is more convenient when it needs to be connected and integrated with other square components or equipment, the flat edge is convenient for connection and fixation, and the square condensate water inlet and outlet can be more convenient for operators to operate during installation and maintenance, for example, when cleaning the pipeline or replacing the sealing element, the square opening provides a wider operation space; even a trapezoidal shape can be used, the trapezoidal structure can flexibly adjust the size ratio of the upper and lower bases according to the specific internal structure difference of the equipment, to meet the requirements of different flow, pressure and installation position, such as in some inclined installation or special control of condensate water flow equipment, the trapezoidal condensate water inlet and outlet can realize precise control of water flow by changing the angle and side length of the trapezoid. The shape of the condensate water inlet 411 and the condensate water outlet 412 is not specifically limited in this application, the user can comprehensively consider the actual engineering demand, equipment characteristics, cost budget and fluid mechanics calculation and other factors, and decide to use which shape of the condensate water inlet 411 and outlet to achieve the optimal running effect and economic benefit.

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

[0052] In an embodiment, as shown in Figure 1 The window air conditioner 100 includes a fan assembly 5 arranged in the second accommodating cavity 12, and the air outlet of the fan assembly 5 faces the condenser 3. During normal operation of the window air conditioner 100, the fan assembly 5 inhales air from the outdoor side and exchanges heat between the condenser 3 and the air by forced convection, thereby reducing the refrigerant temperature of the condenser 3 and improving the heat exchange efficiency of the condenser 3. After the condensate 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 condensate water flowing onto the condenser 3. On the one hand, this can increase the contact area between the condensate water and the condenser 3. On the other hand, this can improve the evaporation speed of the condensate water, greatly improve the heat exchange efficiency between the condensate water and the condenser 3, and further improve the overall energy efficiency of the window air conditioner 100.

[0053] Further, the condenser 3 is arranged at the second end of the second accommodating cavity 12 in the horizontal direction, and the fan assembly 5 is located directly above the condenser 3, so that the air outlet of the fan assembly 5 directly faces the condenser 3. In this way, the vertical space of the second accommodating cavity 12 can be effectively utilized, and excessive arrangement space for the condenser 3 and the fan assembly 5 in the width direction does not need to be reserved, thereby significantly shortening the size of the second accommodating cavity 12 in the width direction and further reducing the overall size of the window air conditioner 100.

[0054] In an embodiment, as shown in Figure 2As shown, the fan assembly 5 comprises a fan cover 51 and a centrifugal fan 52, the fan cover 51 is arranged on the cabinet 1, the centrifugal fan 52 is connected with the fan cover 51, and the condensate water outlet 412 penetrates through the cabinet 1 and extends to the inner side wall of the fan cover 51. It can be understood that the condensate water generated by the evaporator 2 flows along the outer surface of the cabinet 1 under the action of its own gravity and converges in the first accommodating cavity 11. The condensate water in the first accommodating cavity 11 flows from the condensate water inlet 411 of the first drainage channel 41 to the condensate water outlet 412 of the first drainage channel 41. Since the condensate water outlet 412 penetrates through the cabinet 1 and extends to the inner side wall of the fan cover 51, the condensate water flows downward along the inner side wall of the fan cover 51. The centrifugal fan 52 can blow away a part of the condensate water, and the condensate water falls on different areas of the surface of the condenser 3. Further, the centrifugal fan 52 can also blow away the condensate water flowing onto the condenser 3. The condensate water exchanges heat with the condenser 3 during the flow process, thereby increasing the contact area between the condensate water and the condenser 3. On the other hand, it can improve the evaporation speed of the condensate water, greatly improve the heat exchange efficiency between the condensate water and the condenser 3, and further improve the overall energy efficiency of the window type air conditioner 100.

[0055] The centrifugal fan 52 is a machine that relies on input mechanical energy to improve gas pressure and discharge gas. It is a driven fluid machine. According to the principle of converting kinetic energy into potential energy, the centrifugal fan 52 uses a high-speed rotating impeller to accelerate the gas, and then decelerates and changes the flow direction to convert kinetic energy into potential energy (pressure). In a single-stage centrifugal fan 52, the gas enters the impeller from the axial direction, and the gas changes to the radial direction when flowing through the impeller, and then enters the diffuser. In the diffuser, the gas changes the flow direction and the pipe cross-sectional area increases to slow down the airflow. This deceleration converts kinetic energy into pressure energy, so that the centrifugal fan 52 can provide 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 improving the evaporation speed of the condensate water and improving the heat exchange efficiency between the condenser 3 and the condensate water.

[0056] Alternatively, the fan cover 51 can be provided as a whole in a reverse-buckled horn shape. Specifically, the cross-sectional shape of the fan cover 51 can be provided as a sine wave shape. 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 that of the second opening, and the centrifugal fan 52 is arranged at the first opening of the fan cover 51. Therefore, the fan cover 51 can also guide the airflow that leaves the inside of the centrifugal fan 52. The airflow uniformly enters the inside of the fan cover 51, reduces the vortex loss on the blades of the centrifugal fan 52, improves the separation loss generated by the trailing edge, improves the aerodynamic efficiency of the centrifugal fan 52, and reduces the noise generated by the airflow.

[0057] In the specific preparation of the above-mentioned fan cover 51, the material of the fan cover 51 is not limited, and 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 adipate (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, as shown in Figure 5 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 in communication with the condensate outlet 412, and the second end of the first groove 511 is 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 oblique direction of the first groove 511 is related to the rotation direction of the centrifugal fan 52, for example, when the fan blade of the centrifugal fan 52 rotates counterclockwise, the oblique direction of the first groove 511 is arranged along the counterclockwise direction; when the fan blade of the centrifugal fan 52 rotates clockwise, the oblique direction of the first groove 511 is arranged along the clockwise direction.

Under the action of the wind power of the centrifugal fan 52, the condensate water has a centrifugal force when it leaves the inner side wall of the fan cover 51, and the blown condensate water drops on different areas of the surface of the condenser 3, thereby increasing the contact area of the condensate water with the condenser 3, further improving the heat exchange efficiency of the condenser 3, and improving the overall energy consumption of the window type air conditioner 100.

[0063] In one embodiment, as shown in Figure 6 The housing 1 is provided with a cover 13, and the cover 13 is provided with an air inlet 131 and an air outlet 132. The air inlet 131 is arranged close to the centrifugal fan 52 and communicates with the second accommodating cavity 12, and the air outlet 132 is arranged close to the condenser 3 and communicates with the second accommodating cavity 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, thereby increasing the distance between them, so that the outdoor air inlet temperature is less affected by the outdoor air outlet temperature, and the air inlet temperature can be reduced, so that the air conditioning unit is more energy-saving.

[0064] The cover 13 bears the function of ventilation and heat dissipation. The air inlet 131 is arranged close to the centrifugal fan 52 and communicates with the second accommodating cavity 12. The distance between them is strictly designed and optimized to ensure that when the centrifugal fan 52 starts to operate, the negative pressure suction generated by the operation of the centrifugal fan 52 can efficiently suck the external air into the second accommodating cavity 12 with the smallest resistance loss, so as to participate in the subsequent heat exchange process with the condenser 3. The air outlet 132 matched with the air inlet 131 is arranged close to the condenser 3, and its main function is to carry the heat generated by the condenser 3 in the heat exchange process to the external environment, so as to ensure that the heat in the housing 1 can be efficiently dissipated. From the perspective of spatial layout, the air inlet 131 is arranged along a vertical plane, and the air outlet 132 is arranged along a horizontal plane. Based on the principle of fluid mechanics, this unique vertical arrangement can fully utilize the air pressure difference in the vertical direction, optimize the flow rate and flow distribution of the air entering, provide a stable and sufficient cold air source for the subsequent heat exchange process in the second accommodating cavity 12, so that the air entering the second accommodating cavity 12 has a more optimal temperature condition in the initial stage, reduces the air inlet temperature, and makes the window air conditioner 100 more energy-saving. At the same time, the air outlet 132 is arranged along a horizontal plane. According to the principle of hot air rising and air diffusion, the horizontal arrangement design can make the hot air spread in a more uniform manner in the horizontal direction, greatly improve the coverage range and efficiency of heat dissipation, effectively avoid the accumulation of local heat, thereby creating a stable and suitable temperature working environment for the housing 1, and effectively guaranteeing the reliability and stability of the window air conditioner 100 in the long-term operation process, 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 cabinet 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, so as to further avoid the air inlet 131 from sucking the hot air blown by the condenser 3 again, so that the air entering the second accommodating cavity 12 has better temperature conditions in the initial stage, the air inlet temperature is reduced, and the window type air conditioner 100 is more energy-saving as a whole.

[0066] In an embodiment, the window type air conditioner 100 comprises a partition plate 7 arranged in the first accommodating cavity 11, and the fan assembly 5 and the evaporator 2 are arranged on two sides of the evaporator 2 respectively. The partition plate 7 separates the centrifugal fan 52 and the evaporator 2. After the air passes through the centrifugal fan 52, high-pressure air is formed. When the high-pressure air flows into the first accommodating cavity 11 from the air inlet 131, heat exchange occurs in the boundary region where the partition plate 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 exchange with the surface of the evaporator 2 in various ways such as heat conduction and heat convection at the boundary. The inside of the evaporator 2 usually flows with low-temperature refrigerant, and the 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 high-pressure air exchanges heat with the condenser 3, carries away the heat of the condenser 3, and at the same time accelerates the evaporation speed of the condenser water on the surface of the condenser 3, thereby improving the heat exchange efficiency of the condenser 3 and the overall energy efficiency of the machine.

[0067] In an embodiment, the window type air conditioner 100 comprises a compressor 8 arranged in the first accommodating cavity 11. The exhaust port of the compressor 8 is connected with the refrigerant inlet of the condenser 3, and the suction port of the compressor 8 is connected with the refrigerant outlet of the evaporator 2. The refrigerant outlet of the condenser 3 is connected with the refrigerant inlet of the throttling device, and the refrigerant outlet of the throttling device is connected with the refrigerant inlet of the evaporator 2. The compressor 8, the condenser 3, the throttling device and the evaporator 2 form a refrigeration cycle circuit. The compressor 8 sucks in low-pressure refrigerant from the evaporator 2, raises the refrigerant from low pressure to high pressure, and makes the refrigerant flow continuously in the refrigeration cycle circuit. The refrigerant condenses into refrigerant liquid with higher pressure and higher temperature in the condenser 3. This part of refrigerant liquid enters the throttling device, is throttled by the throttling device, and 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 refrigerant vapor with lower pressure. The refrigerant vapor enters the suction port of the compressor 8, thereby realizing the refrigerant circulation.

[0068] Optionally, a throttling device is used to throttle the high-pressure refrigerant liquid from the condenser 3 to a low-pressure refrigerant liquid, while regulating the refrigerant flow into the evaporator 2, when the throttling device is regulated to the maximum opening, the refrigerant is at the maximum flow in the refrigeration circuit, the throttling device can be but not limited to: a capillary tube, a throttling short pipe, a thermal expansion valve, an electronic expansion valve, a float valve, a throttling orifice plate, a manual expansion valve, etc.
