Description

Technical Field

[0001] This invention belongs to the field of air conditioning equipment technology, and particularly relates to a window air conditioner. Background Technology

[0002] Window air conditioners are widely used due to their small size, low price, and easy installation. In existing technology, when the air conditioner is in cooling mode, the condensate in the water collection tank is pumped to the water distribution unit, and then flows from the water distribution unit to the surface of the outdoor heat exchanger. The condensate is used to lower the temperature of the heat exchange tubes in the outdoor heat exchanger, effectively improving heat exchange efficiency. However, this solution is only suitable for the air conditioner in cooling mode. When the air conditioner is in heating mode, the temperature of the outdoor heat exchanger is low, and the condensate flowing to the surface of the outdoor heat exchanger is prone to frost formation, which reduces heat exchange efficiency. The condensate at the bottom of the outdoor heat exchanger is prone to freezing, causing the pump to be unable to pump water. Thus, the condensate cannot be fully utilized and excess condensate cannot be disposed of in a timely manner. Summary of the Invention

[0003] In view of this, the present invention provides a window air conditioner to solve the problems in the prior art where condensate water accumulates on the surface of the outdoor heat exchanger when the window air conditioner is in heating mode, resulting in reduced heat exchange efficiency and insufficient utilization of condensate water.

[0013] Further optionally, the reversing valve includes a first working position and a second working position; when the reversing valve is in the first working position, the water inlet is connected to the first water outlet, and the water inlet is not connected to the second water outlet.

[0014] When the reversing valve is in the second working position, the water inlet is not connected to the first water outlet, and the water inlet is connected to the second water outlet.

[0015] Further optionally, the window air conditioner also includes a controller; the water supply mechanism also includes a liquid level detection element for detecting the liquid level in the first water collection area; and the reversing valve is an electromagnetic reversing valve.

[0016] The controller is electrically connected to the reversing valve, the liquid level detection device, and the pump. The controller controls the reversing valve to switch and the pump to run according to the operating mode of the window air conditioner and the liquid level in the first water collection area.

[0017] Optionally, the window air conditioner further includes a desiccant mechanism, which is located below the outlet end of the first water pipe, and includes a rotating shaft and desiccant fan blades; the rotating shaft is rotatably mounted on the chassis, and multiple desiccant fan blades are arranged circumferentially on the rotating shaft.

[0018] Further optionally, the moisture absorption mechanism and the outlet of the first water supply pipe are both located on the windward side of the outdoor heat exchanger; the moisture absorption fan blades can rotate with the airflow from the outdoor heat exchanger, thereby evaporating the condensate flowing from the outlet of the first water supply pipe onto the moisture absorption fan blades.

[0020] Optionally, a temperature switch is provided at the outlet end of the first water supply pipe; the second water supply pipe has a throttling section, and the throttling section is close to the outlet end of the second water supply pipe.

[0021] Compared with the prior art, the main advantages of the present invention are as follows:

[0022] (1) The outlet of the first water supply pipe is located outside the outdoor heat exchanger. When the window air conditioner is in cooling mode, the condensate in the water collection area flows to the outdoor heat exchanger through the first water supply pipe. The outlet of the second water supply pipe is located between the outdoor fan blades and the outdoor heat exchanger. When the window air conditioner is in heating mode, the condensate in the water collection area flows to the outdoor fan blades through the second water supply pipe. Whether the window air conditioner is in cooling mode or heating mode, the cooling capacity of the condensate can be fully utilized, which improves the heat exchange effect of the outdoor heat exchanger. At the same time, excess condensate can be treated in time, avoiding pollution of the outdoor environment by the condensate, improving the working efficiency of the window air conditioner, and solving the problems of insufficient utilization of condensate and low removal efficiency.

[0023] (2) An electric heating belt is installed in the water collection area. When the window air conditioner is in heating mode, the electric heating belt heats the water to prevent the condensate in the water collection area from freezing into ice and causing the pump to be unable to pump water. A baffle is installed between the outdoor fan blade and the second water collection area to solve the problem that the condensate cannot be quickly collected under the action of wind pressure, especially when the air conditioner is in heating mode.

[0024] (3) The height of the first water collection zone is lower than that of the second water collection zone, so that the condensate can be collected in the first water collection zone in a timely manner; the first water collection zone is equipped with a liquid level detection device, and the operation of the pump is controlled in real time and accurately according to the liquid level change of the first water collection zone, so as to ensure the performance of the pump and extend the service life of the pump, and avoid the problem of the pump still running when the condensate is drained, which leads to damage and shortened life.

[0025] (4) A moisture absorption mechanism is installed below the second water supply pipe. The moisture absorption fan blades rotate with the air outlet of the outdoor heat exchanger, so that the condensate flowing on the moisture absorption fan blades evaporates quickly, achieving high-efficiency water removal. Through the reversing valve, the pump can deliver water to different water supply pipes, so as to make full use of the condensate of the window air conditioner in different modes. The second water supply pipe forms a throttling section, which increases the water pressure and improves the atomization effect of the nozzle of the second water supply pipe, so as to achieve the purpose of fully atomizing water.

[0038] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” used in the embodiments of this invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0040] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0041] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0042] In existing window air conditioners, when the air conditioner is in cooling mode, the condensate in the water collection tank is pumped to the water distribution unit, and then flows from the water distribution unit to the surface of the outdoor heat exchanger. The condensate is used to lower the temperature of the heat exchange tubes in the outdoor heat exchanger, effectively improving heat exchange efficiency. However, this solution is only suitable for the air conditioner in cooling mode. When the air conditioner is in heating mode, the temperature of the outdoor heat exchanger is low, and the condensate flowing to the surface of the outdoor heat exchanger is prone to frost formation, which reduces heat exchange efficiency. The condensate at the bottom of the outdoor heat exchanger is prone to freezing, causing the pump to be unable to pump water. In addition, the condensate is not fully utilized.

[0043] This invention creatively provides a window air conditioner, including a chassis, an outdoor heat exchanger, an outdoor fan blade, and a water supply mechanism. The chassis forms a water collection area. The outdoor heat exchanger and the outdoor fan blade are both located on the outdoor side of the chassis, with the outdoor fan blade located on the inner side of the outdoor heat exchanger. The water supply mechanism includes a first water supply pipe and a second water supply pipe. Condensate in the water collection area can flow to the outdoor heat exchanger through the first water supply pipe, and condensate in the water collection area can flow to the outdoor fan blade through the second water supply pipe.

[0044] When a window air conditioner is in cooling or heating mode, the cooling capacity of the condensate can be fully utilized, and excess condensate can be treated in time, improving the condensate removal efficiency, ensuring the reliable operation of the window air conditioner, and solving the problems of insufficient utilization of condensate and low removal efficiency.

[0045] Example 1

[0046] <Catchment Area>

[0047] like Figure 1 , Figure 2a , Figure 2b and Figure 3 As shown, this embodiment provides a window air conditioner 1, including a chassis 11, an outdoor heat exchanger 12, an outdoor fan blade 13, a compressor, a motor, an indoor fan blade, an indoor heat exchanger 14, and a water supply mechanism 2; the outdoor heat exchanger 12, the outdoor fan blade 13, the motor, the indoor fan blade, and the indoor heat exchanger 14 are sequentially arranged on the chassis 11 along its length; the outdoor heat exchanger 12 and the outdoor fan blade 13 are located on the outdoor side of the chassis 11, and the indoor heat exchanger 14 and the indoor fan blade are located on the indoor side of the chassis 11; a transmission mechanism is provided between the motor and the outdoor fan blade 13 and the indoor fan blade. The transmission mechanism includes an input end and two output ends. The input end is driven and connected to the output shaft of the motor, one output shaft is driven and connected to the outdoor fan blade 13, and the other output shaft is driven and connected to the indoor fan blade. When the motor is running, the outdoor fan blade 13 and the indoor fan blade rotate simultaneously. The compressor is located at one end of the width direction of the chassis 11. The chassis 11 forms a water collection area. The chassis 11 includes a bottom wall and side walls surrounding the bottom wall. The water collection area is a groove formed by the bottom wall protruding downwards from the chassis 11, which can collect the condensate generated by the outdoor heat exchanger 12 and the indoor heat exchanger 14.

[0048] Furthermore, such as Figure 4 and Figure 5As shown, the water collection area is located on the outdoor side of the chassis 11, and includes a first water collection area 111, a second water collection area 112, and a third water collection area 113 connected in sequence. The first water collection area 111 is located at one end of the width direction of the chassis 11, on one side of the outdoor fan blade 13 and away from the compressor. The third water collection area 113 is located at the other end of the width direction of the chassis 11, on the other side of the outdoor fan blade 13 and close to the compressor. Condensate from the compressor can flow to the third water collection area 113. The second water collection area 112 is located below the outdoor fan blade 13, and condensate from the outdoor fan blade 13 can flow to the second water collection area 112. The first water collection area 111, the second water collection area 112, and the third water collection area 113 are U-shaped in overall structure.

[0049] like Figure 4 and Figure 5 As shown, in response to the problem that condensate cannot be collected in the first water collection area 111 in a timely manner, this embodiment proposes that the height of the first water collection area 111 is lower than the height of the second water collection area 112, so that the condensate in the second water collection area 112 can flow to the first water collection area 111; the height of the second water collection area 112 is lower than or equal to the height of the third water collection area 113; preferably, the height of the second water collection area 112 is equal to the height of the third water collection area 113, so that the condensate in the third water collection area 113 can flow to the second water collection area 112.

[0050] like Figure 4 and Figure 5 As shown, to address the problem that condensate in the water collection area easily freezes when the air conditioner is in heating mode, causing the pump 25 to be unable to pump water, this embodiment proposes that the window air conditioner 1 also includes an electric heating belt 16. Electric heating belts 16 are installed in the first water collection area 111, the second water collection area 112, and the third water collection area 113. When the air conditioner is in heating mode, electricity is supplied to the electric heating belt 16 to heat the condensate in the water collection area, preventing the condensate in the water collection area from freezing into ice, or melting the ice into water, achieving the purpose of rapid water collection and drainage, preventing the condensate in the water collection area from freezing into ice and causing the pump 25 to be unable to pump water, and ensuring that the condensate in the water collection area can be treated in a timely manner.

[0051] To address the issue that condensate in the second water collection area 112 cannot collect in the first water collection area 111 due to wind pressure during outdoor fan blade 13 operation, this embodiment proposes that the window air conditioner 1 also includes a baffle plate 27. The baffle plate 27 is disposed on the chassis 11 and located between the second water collection area 112 and the outdoor fan blade 13. At least a portion of the baffle plate 27 covers the top of the second water collection area 112. Under the action of gravity, the condensate in the second water collection area can smoothly enter the first water collection area 111, thus avoiding the problem of condensate splashing in the second water collection area 112 and failing to collect in the first water collection area 111 caused by the outdoor fan blade 13 during operation, especially when the air conditioner is in heating mode.

[0052] <Water conveyance mechanism>

[0053] like Figure 1 , Figure 2a and Figure 4 As shown, the window air conditioner 1 includes a rear partition 15, which is disposed on top of the outdoor heat exchanger 12 and the outdoor fan blade 13. The water supply mechanism 2 includes a first water supply pipe 21 and a second water supply pipe 22. The outlet of the first water supply pipe 21 is located outside the outdoor heat exchanger 12. When the window air conditioner 1 is in cooling mode, the condensate in the water collection area can flow to the outdoor heat exchanger 12 through the first water supply pipe 21, thereby improving the heat exchange efficiency of the outdoor heat exchanger 12. The outlet of the second water supply pipe 22 is disposed on the rear partition 15 and located between the outdoor fan blade 13 and the outdoor heat exchanger 12. When the window air conditioner 1 is in heating mode, the condensate in the water collection area can flow to the outdoor fan blade 13 through the second water supply pipe 22. Under the high pressure of the fan blade, the condensate is distributed to the outdoor heat exchanger 12, thereby removing the condensate and increasing the heat exchange efficiency of the outdoor heat exchanger 12, while preventing condensate from frosting on the surface of the outdoor heat exchanger 12.

[0054] Alternatively, when the window air conditioner 1 is in cooling mode, the condensate in the water collection area can flow to the outdoor heat exchanger 12 through the first water supply pipe 21, and the condensate in the water collection area can flow to the outdoor fan blade 13 through the second water supply pipe 22. This method has high water removal efficiency and avoids the problem of condensate overflow in the water collection area.

[0055] In summary, regardless of whether the window air conditioner 1 is in cooling or heating mode, the cooling capacity of the condensate can be fully utilized, improving the heat exchange effect of the outdoor heat exchanger 12. At the same time, excess condensate can be treated in a timely manner, avoiding pollution of the outdoor environment by the condensate, improving the working efficiency of the window air conditioner 1, solving the problems of insufficient utilization of condensate and low removal efficiency, and solving the problem of needing to install a drain pipe for the window air conditioner 1.

[0056] like Figure 1 , Figure 2a and Figure 4As shown, to address the issues of narrow coverage and slow evaporation rate of the condensate flowing from the outlet ends of the first water supply pipe 21 and the second water supply pipe 22, this embodiment proposes that the outlet end of the first water supply pipe 21 is equipped with an atomizing nozzle 211, and the outlet end of the second water supply pipe 22 is equipped with a spray head 221. At least a portion of the atomizing nozzle 211 of the first water supply pipe 21 faces the outdoor heat exchanger 12, and the condensate sprayed from the atomizing nozzle 211 of the first water supply pipe 21 is sprayed towards the outdoor heat exchanger 12 in different directions. Because this portion of the condensate has a small and dispersed particle size, the coverage is narrow and the evaporation rate is slow. The large surface area and fast evaporation rate improve the heat exchange efficiency of the outdoor heat exchanger 12 and the condensate removal efficiency, avoiding the inefficient circulation of condensate in the water collection area and water conveying mechanism 2; at least a portion of the nozzle 221 of the second water conveying pipe 22 faces the outdoor fan blade 13, and the condensate sprayed from the nozzle 221 of the second water conveying pipe 22 is sprayed towards the outdoor fan blade 13 in different directions. Because the particle size of this part of the condensate is small and dispersed, the coverage area is large and the evaporation rate is fast, which improves the evaporation rate of the condensate and avoids the inefficient circulation of condensate in the water collection area and water conveying mechanism 2.

[0057] Preferably, both the outlet end of the first water pipe 21 and the outlet end of the second water pipe 22 are provided with atomizing nozzles 211.

[0058] To address the issues of insufficient water pressure and poor atomization effect in the water flowing from the second water supply pipe 22, this embodiment proposes that the second water supply pipe 22 has a throttling section 222, which is located near the outlet end of the second water supply pipe 22. When the condensate flows through the throttling section 222, the water pressure increases rapidly, improving the atomization effect of the nozzle 221 of the second water supply pipe 22 and achieving the purpose of fully atomizing the water. This allows the condensate to be rapidly sprayed from the nozzle 221 of the second water supply pipe 22 towards the outdoor fan blade 13. The water droplets collide with the outdoor fan blade 13, and the large-diameter water droplets become small-diameter water droplets, which is conducive to the rapid evaporation of the water droplets into water vapor and their dissipation with the wind.

[0059] To address the issue that the condensate outlet cannot be adapted to the operating mode of the window air conditioner 1, this embodiment proposes that the water supply mechanism 2 includes a reversing valve 24, a pump 25, a main water supply pipe 23, and a support frame 28. The reversing valve 24 has an inlet, a first outlet, and a second outlet. The inlet is located on one side of the reversing valve 24, and the first and second outlets are located on the other side. The pump 25 is installed in the first water collection area 111. Since the height of the first water collection area 111 is lower than the height of the second water collection area 112, the pump 25 can preferentially draw water. The support frame 28 covers the top of the pump 25, providing protection for the pump 25.

[0060] The inlet of pump 25 is connected to the first water collection area 111, and the outlet of pump 25 is connected to the inlet through the main water supply pipe 23; the inlet end of the first water supply pipe 21 is connected to the first outlet, and the inlet end of the second water supply pipe 22 is connected to the second outlet; specifically, the distance between the inlet of pump 25 and the bottom wall of the first water collection area 111 is h, which satisfies 2mm≤h≤6mm, to prevent dirt in the first water collection area 111 from being sucked into pump 25, affecting the normal operation and life of pump 25;

[0061] When the liquid level in the first water collection zone 111 is higher than the minimum preset level, the control pump 25 is operated and the reversing valve 24 is in the preset working position, so that the condensate in the first water collection zone 111 flows to the outdoor heat exchanger 12 through the pump 25, the main water supply pipe 23 and the first water supply pipe 21, or the condensate in the first water collection zone 111 flows to the space between the outdoor heat exchanger 12 and the outdoor fan blade 13 through the pump 25, the main water supply pipe 23 and the second water supply pipe 22.

[0062] Furthermore, the reversing valve 24 includes a first working position and a second working position; when the reversing valve 24 is in the first working position, the inlet is connected to the first outlet and the inlet is not connected to the second outlet; at this time, the condensate in the first water collection area 111 can flow to the outdoor heat exchanger 12 through the first water supply pipe 21.

[0063] When the reversing valve 24 is in the second working position, the water inlet is not connected to the first water outlet, but is connected to the second water outlet; at this time, the condensate in the first water collection area 111 can flow to the outdoor fan blade 13 through the second water supply pipe 22.

[0064] In addition, the reversing valve 24 also includes a third working position; when the reversing valve 24 is in the third working position, the water inlet is connected to both the first water outlet and the second water outlet; at this time, a portion of the condensate in the first water collection area 111 can flow to the outdoor heat exchanger 12 through the first water supply pipe 21, and another portion of the condensate in the first water collection area 111 can flow to the outdoor fan blade 13 through the second water supply pipe 22; when the window air conditioner 1 is in cooling mode and there is a large amount of condensate in the water collection area, the reversing valve 24 can be in the third working position to discharge the condensate in the water collection area in a timely manner, which has high water removal efficiency and avoids the overflow of condensate from the chassis 11 due to excessive condensate, which could cause safety hazards and reduce the user experience.

[0065] To address the issue of pump 25 continuing to operate even when there is low condensate in the water collection area, leading to pump 25 damage, this embodiment proposes that the window air conditioner 1 also includes a controller; the water delivery mechanism 2 also includes a liquid level detection element 26 installed on the support frame 28 for detecting the liquid level in the first water collection area 111; and the reversing valve 24 is an electromagnetic reversing valve 24.

[0066] The controller is electrically connected to the reversing valve 24, the liquid level detection element 26 and the pump 25. The controller controls the reversing valve 24 to switch and controls the operation of the pump 25 in real time and accurately according to the operating mode of the window air conditioner 1 and the liquid level change of the first water collection area 111, so as to ensure the performance of the pump 25 and extend the service life of the pump 25.

[0067] When the window air conditioner 1 is in cooling mode, if the liquid level in the first water collection zone 111 is lower than the minimum preset level, the control pump 25 stops running to prevent damage and reduced lifespan of the pump 25 when the condensate is drained. If the liquid level in the first water collection zone 111 is higher than the minimum preset level, the control pump 25 runs and the control reversing valve 24 is in the first working position, allowing the condensate in the first water collection zone 111 to flow to the outdoor heat exchanger 12 through the first water supply pipe 21, thus improving the heat exchange efficiency of the outdoor heat exchanger 12. If the liquid level in the first water collection zone 111 is higher than the maximum preset level, the control pump 25 runs and the control reversing valve 24 is in the third working position, allowing a portion of the condensate in the first water collection zone 111 to flow to the outdoor heat exchanger 12 through the first water supply pipe 21, and another portion of the condensate in the first water collection zone 111 to flow to the outdoor fan blade 13 through the second water supply pipe 22, thus timely draining the condensate in the first water collection zone 111.

[0068] When the window air conditioner 1 is in heating mode, the control pump 25 stops running when the liquid level in the first water collection zone 111 is lower than the minimum preset level; when the liquid level in the first water collection zone 111 is higher than the minimum preset level, the control pump 25 runs and the control reversing valve 24 is in the second working position, so that the condensate in the first water collection zone 111 can flow to the outdoor fan blade 13 through the second water supply pipe 22.

[0069] Moisture-absorbing mechanism

[0070] like Figure 1 , Figure 4 and Figure 6 As shown, in response to the problems of condensate dripping from the outlet of the first water pipe 21 affecting the surrounding environment and slow evaporation rate, this embodiment proposes that the window air conditioner 1 further includes a desiccant mechanism 3. The desiccant mechanism 3 is located below the outlet of the first water pipe 21, and the desiccant mechanism 3 includes a rotating shaft 31 and desiccant fan blades 32. The rotating shaft 31 is rotatably mounted on the chassis 11 via a base 33. Multiple desiccant fan blades 32 are arranged along the circumference of the rotating shaft 31. The axial direction of the rotating shaft 31 is consistent with the thickness direction of the window air conditioner 1, and the length direction of the desiccant fan blades 32 is consistent with the axial direction of the rotating shaft 31.

[0071] Furthermore, the outlet ends of the desiccant mechanism 3 and the first water supply pipe 21 are both located on the windward side of the outdoor heat exchanger 12; the water flows from the outlet end of the first water supply pipe 21 to the desiccant fan blade 32, and the desiccant fan blade 32 can rotate with the air outlet of the outdoor heat exchanger 12, thereby evaporating the condensate on the desiccant fan blade 32 and achieving high-efficiency water removal.

[0072] Example 2

[0073] Unlike Embodiment 1, a reversing valve 24 is not provided. Instead, a temperature switch is installed at the outlet of the first water supply pipe 21. Based on the principle of thermal expansion and contraction, the temperature switch naturally opens and closes the first water supply pipe 21 according to temperature changes. The second water supply pipe 22 has a throttling section 222, which is close to the outlet of the second water supply pipe 22. Under the pressure of the condensate, the condensate will naturally choose the first water supply pipe 21 with lower pressure for dewatering. When the ambient temperature is high, the temperature switch closes, and the condensate flows through the first water supply pipe 21 to the outdoor heat exchanger 12, forming atomized dewatering.

[0074] In addition, the temperature switch can also be mechanical. The temperature switch is electrically connected to the controller. Controlling the temperature switch can open or close the first water supply pipe 21 to remove condensate from the first water collection area 111.

[0075] Exemplary embodiments of this disclosure have been specifically shown and described above. It should be understood that this disclosure is not limited to the detailed structures, arrangements, or implementations described herein; rather, this disclosure is intended to cover various modifications and equivalent arrangements contained within the spirit and scope of the appended claims.
