Description

Technical Field

[0001] The utility model relates to the field of air conditioners, and particularly to an integrated air conditioner and its chassis. Background Art

[0002] The outdoor fan of an integrated air conditioner generally adopts a wind blade with a water spraying ring. When the air conditioner is refrigerating, the condensed water generated by the indoor heat exchanger is led outdoors. Through the rotation of the wind blade, the relatively cold water is thrown onto the fins of the outdoor heat exchanger for heat dissipation, thereby reducing the power of the whole machine and improving the energy efficiency. Generally, the structure of the chassis is to design a water collecting tank below the outdoor fan, and the condensed water converges from all directions into the water collecting tank to achieve water spraying by the wind blade. When the air conditioner is heating, the outdoor heat exchanger acts as an evaporator to generate condensed water, and the condensed water converges into the water collecting tank at the bottom of the wind blade. In severe cold and low temperature working conditions, the condensed water cannot be discharged in time, the water freezes on the chassis, and the wind blade will hit the ice, causing damage and affecting the normal use of the air conditioner.

[0003] To solve this problem, some existing solutions attempt to design a diversion groove to optimize the drainage effect. For example, the diversion groove passes through the bottom of the rear partition and is parallel to the end face of the water spraying ring of the outdoor fan. This design utilizes the air pressure difference inside and outside the rear partition and the centrifugal force generated by the rotation of the fan, making the accumulated water below the outdoor fan easy to drain outside the rear partition. Although this solution improves the problem of accumulated water at the bottom of the fan to a certain extent, it brings new problems under the refrigeration working condition. Due to the decrease in the water level of the water collecting tank, the amount of water blown by the outdoor fan to the outdoor heat exchanger decreases, resulting in a reduction in the evaporation heat dissipation amount on the surface of the outdoor heat exchanger, and thus affecting the refrigeration energy efficiency of the system.

[0004] Therefore, how to ensure effective drainage while taking into account the system energy efficiency under the refrigeration working condition has become a key problem to be solved urgently in the design of a through-wall heat pump type integrated air conditioner. Summary of the Utility Model

[0005] An object of the first aspect of the utility model is to improve the system energy consumption under the refrigeration working condition on the premise of effective drainage.

[0006] Another object of the first aspect of the utility model is to shorten the flow path of the condensed water in the diversion groove and improve the discharge speed of the condensed water.

[0007] Still another object of the first aspect of the utility model is to optimize the layout design of the drainage tank and the drainage valve to achieve the maximum utilization of space.

[0008] Particularly, according to the first aspect of the utility model, the utility model provides a chassis of an integrated air conditioner, including:

[0009] The chassis body is provided with a water collecting trough and a diversion trough. The water collecting trough is arranged below the outdoor fan and is used for collecting the condensed water generated from the indoor heat exchanger. The diversion trough is located below the outdoor heat exchanger and is communicated with the rear side of the water collecting trough, and is used for collecting the condensed water flowing out of the water collecting trough and guiding its flow direction.

[0010] Optionally, the diversion trough is closer to the rear side of the chassis body than the water collecting trough. The diversion trough includes a first trough section and a second trough section. The first trough section extends along the lateral direction of the chassis body, and the second trough section extends along the front-rear direction of the chassis body and communicates the water collecting trough and the second trough section.

[0011] Optionally, the water collecting trough has one end close to the first trough section and one end far from the first trough section. The first trough section is communicated with the end of the water collecting trough close to itself through the second trough section.

[0012] Optionally, the ratio range of the lateral width of the first trough section to the lateral width of the water collecting trough is 1:3 to 1:5.

[0013] Optionally, the bottom surface of the water collecting trough is higher than the bottom surface of the diversion trough.

[0014] Optionally, the chassis body is further provided with a drainage trough, and the drainage trough is communicated with the diversion trough and is used for discharging the condensed water collected by the diversion trough out of the chassis body.

[0015] Optionally, a drainage port is opened at the bottom of the drainage trough, and a drainage valve for opening and closing the drainage port is provided.

[0016] Optionally, the drainage trough extends along the front-rear direction of the chassis body, and the drainage valve is installed along the front-rear direction of the chassis body.

[0017] Optionally, the bottom surface of the drainage trough is higher than the bottom surface of the diversion trough.

[0018] According to the second aspect of the present utility model, the present utility model provides an integrated air conditioner, which is characterized in that it includes the chassis of the integrated air conditioner according to any one of the above.

[0019] The chassis of the integrated air conditioner of the present utility model has a diversion groove communicating with the rear side of the water collection tank, that is, the water outlet of the water collection tank is arranged at the rear side. In this way, when the outdoor fan operates, the attached water splashing ring during rotation will not push the condensed water in the water collection tank to one side and cause overflow. Instead, through its dynamic stirring effect, it slows down the natural backward outflow speed of the condensed water, effectively maintaining the water level stability in the water collection tank. When there is sufficient water level in the water collection tank, the water splashing ring can stably and continuously sprinkle the condensed water onto the outdoor heat exchanger. During this process, the condensed water not only helps the outdoor heat exchanger to conduct effective heat exchange, but also significantly reduces the energy consumption of the air conditioner under the refrigeration condition.

[0020] Furthermore, for the chassis of the integrated air conditioner of the present utility model, its first groove section communicates with one end of the water collection tank close to itself through the second groove section, ensuring that the condensed water can flow smoothly from the water collection tank into the diversion groove without going through complex turning or bypassing. Due to this segmented and clearly - directed layout of the diversion groove, after the condensed water enters the diversion groove from the water collection tank, its flow path is significantly shortened. The distance that the condensed water needs to flow through is shorter, thereby reducing the flow resistance and flow time, and improving the discharge efficiency.

[0021] Furthermore, for the chassis of the integrated air conditioner of the present utility model, the drainage groove extends along the front - to - rear direction of the chassis body, making full use of the front - to - rear space of the chassis body. The drain valve is also installed along the front - to - rear direction of the chassis body, echoing the layout of the drainage groove. This installation method ensures that the drain valve can directly receive the condensed water from the drainage groove without additional turning or guiding structures. Through the front - to - rear direction layout of the drainage groove and the drain valve, the present utility model maximizes the space utilization, not only reducing the waste of the internal space of the chassis, but also making the entire air conditioner more compact and efficient.

[0038] In the attached Figure 1 , 3 -5, for similar components in the prior art as shown in the attached Figure 2 figure, the same reference numerals will be used. Additionally, the technical solutions between various embodiments of the present utility model can be combined with each other, but it must be based on the premise that those of ordinary skill in the art can implement them.

[0039] The present utility model provides an integrated air conditioner 1 and its chassis 10, aiming to solve the problem that the condensed water in the water collecting tank 110 in the prior art is easily drained quickly and it is difficult to maintain the water level for water spraying in the water collecting tank 110.

[0040] Different from common split air conditioners, the integrated air conditioner 1 emphasizes the centralized layout of all components, and all components are integrated in a compact machine body. There is no need to install indoor and outdoor units separately like split air conditioners, nor to lay complex connection pipes. This not only saves installation time and cost but also reduces potential problems during the installation process.

[0041] The compact design of the integrated air conditioner 1 makes the space it occupies much smaller than that of split air conditioners. This is particularly important for environments with limited space (such as small apartments, flats, or offices) because it can save valuable indoor space for users while keeping the indoor decoration clean and beautiful.

[0042] Since all components are concentrated in one machine body, the maintenance and repair of the integrated air conditioner 1 become easier. Maintenance personnel can easily access and inspect each component without having to shuttle back and forth between indoors and outdoors like split air conditioners. This reduces the maintenance difficulty, shortens the repair time, and improves the repair efficiency.

[0043] Figure 1 is a schematic structural diagram of an integrated air conditioner 1 according to an embodiment of the present utility model, as Figure 1As shown, the integrated air conditioner 1 may include a chassis 10, an indoor heat exchanger, an indoor fan, an outdoor heat exchanger 20, and an outdoor fan 30. Among them, the indoor heat exchanger and the indoor fan are arranged in the front side area of the chassis 10, and the outdoor heat exchanger 20 and the outdoor fan 30 are arranged in the rear area of the chassis 10. The illustration of the present utility model will mainly focus on the rear area of the chassis 10, while the illustrations of the indoor heat exchanger and the indoor fan are omitted.

[0044] The chassis 10 serves as the support foundation for the entire air conditioner, mainly used to bear the weights of various components and the vibrations during operation. The indoor heat exchanger, the indoor fan, the outdoor fan 30, and the outdoor heat exchanger 20 are arranged in sequence from front to back on the chassis 10.

[0045] Among them, the indoor heat exchanger is mainly used to absorb or release the heat of the indoor air. In the cooling mode, the indoor heat exchanger works as an evaporator, absorbing the heat of the indoor air to cool it down; in the heating mode, the indoor heat exchanger works as a condenser, releasing heat to the indoor air to heat it up.

[0046] The indoor fan is mainly used to promote the circulation of indoor air, blowing the indoor air through the indoor heat exchanger to accelerate the heat exchange process. In the cooling mode, the indoor fan blows the cooled air into the room to lower the room temperature; in the heating mode, the indoor fan blows the heated air into the room to raise the room temperature.

[0047] The outdoor heat exchanger 20 is mainly used to absorb or release the heat of the outdoor air. In the cooling mode, the outdoor heat exchanger 20 works as a condenser, releasing the heat absorbed from the indoor to the outdoor air; in the heating mode, the outdoor heat exchanger 20 works as an evaporator, absorbing heat from the outdoor air.

[0048] The outdoor fan 30 is mainly used to promote the circulation of outdoor air, blowing the outdoor air through the outdoor heat exchanger 20 to accelerate the heat exchange process. In the cooling mode, the outdoor fan 30 dissipates the heated air to the outdoor; in the heating mode, the outdoor fan 30 helps the outdoor heat exchanger 20 absorb heat from the outdoor air.

[0049] Since both the indoor heat exchanger and the outdoor heat exchanger 20 will absorb heat and cause the water vapor in the air to condense into condensate when used as an evaporator, an effective drainage structure needs to be provided inside the chassis 10 to prevent the condensate from accumulating inside the chassis 10, avoiding equipment corrosion, increased thermal resistance, energy consumption waste, and possible equipment failures, etc.

[0050] Figure 2 is a schematic plan view of the chassis 10 of the integrated air conditioner 1 in the prior art, as Figure 2As shown, the chassis 10 includes a chassis body 10. A water collecting tank 110, a water guiding tank 120, and a drain tank 130 are provided on the chassis body 10. Among them, the water collecting tank 110 is used to collect the condensed water generated by the indoor heat exchanger, the water guiding tank 120 is used to guide the condensed water in the water collecting tank 110 to flow into the drain tank 130, and the drain tank 130 is used to discharge the collected condensed water out of the chassis body 10 to maintain the interior of the chassis body 10 dry.

[0051] For the chassis 10 of this integrated air conditioner, the water guiding tank 120 passes through the bottom of the rear partition (the water guiding tank 120 extends horizontally from one side of the water collecting tank 110), and the water guiding tank 120 is parallel to the end face of the water spraying ring of the outdoor fan 30, aiming to promote the drainage of accumulated water by using the wind pressure difference and centrifugal force. However, when the outdoor fan 30 is operating, if the drainage efficiency is too high, it may cause the water level in the water collecting tank 110 to drop rapidly, thereby reducing the amount of water sprayed by the water spraying ring onto the outdoor heat exchanger 20.

[0052] In the cooling mode, the outdoor heat exchanger 20 serves as an evaporator, and the evaporation heat dissipation on the fin surface is crucial for the refrigeration energy efficiency of the system. If the amount of water sprayed by the water spraying ring onto the outdoor heat exchanger 20 decreases, it will reduce the humidity of the fin surface, thereby affecting its evaporation heat dissipation effect and ultimately leading to a decrease in refrigeration energy efficiency.

[0053] The chassis 10 of the integrated air conditioner 1 provided by the present utility model optimizes the structure in view of the above problems and solves the problem of the difficulty in balancing drainage efficiency and refrigeration energy efficiency.

[0054] Figure 3 It is a schematic structural diagram of the chassis 10 according to an embodiment of the present utility model. Figure 4 It is a schematic cross-sectional view of the water collecting tank 110 and the water guiding tank 120 according to an embodiment of the present utility model. Figure 5 It is a schematic cross-sectional view of the drain tank 130 and the water guiding tank 120 according to an embodiment of the present utility model.

[0055] As Figures 3 to 5 shown, the chassis 10 of the integrated air conditioner 1 includes a chassis body 10. The chassis body 10 is provided with a water collecting tank 110 and a water guiding tank 120. The water collecting tank 110 is arranged below the outdoor fan 30 and is used to collect the condensed water generated from the indoor heat exchanger. The water guiding tank 120 is located below the outdoor heat exchanger 20 and is communicated with the rear side of the water collecting tank 110, and is used to collect the condensed water flowing out of the water collecting tank 110 and guide its flow direction.

[0056] The chassis 10 of the integrated air conditioner 1 in this embodiment has a diversion groove 120 communicating with the rear side of the water collection tank 110, that is, the water outlet of the water collection tank 110 is arranged at the rear side. In this way, when the outdoor fan 30 operates, the attached water spraying ring during rotation not only does not push the condensed water in the water collection tank 110 to one side and cause overflow, but instead slows down the natural backward outflow speed of the condensed water through its dynamic stirring effect, effectively maintaining the water level stability in the water collection tank 110. When the water level in the water collection tank 110 is sufficient, the water spraying ring can stably and continuously sprinkle the condensed water onto the outdoor heat exchanger 20. During this process, the condensed water not only helps the outdoor heat exchanger 20 to conduct effective heat exchange, but also significantly reduces the energy consumption of the air conditioner under the refrigeration condition.

[0057] The diversion groove 120 is closer to the rear side of the chassis body 10 than the water collection tank 110. In this way, the diversion groove 120 and the front end surface of the water spraying ring can be staggered in the front and rear directions. When the outdoor fan 30 rotates at a high speed, the combined action of the wind pressure difference and centrifugal force generated by it causes the water droplets thrown out by the water spraying ring to hit the rear partition and the tube plate wall surface of the outdoor heat exchanger 20. Some water droplets can flow down along the flow, and finally converge and flow back to the water collection tank 110 located below, providing a continuous water source for the water spraying ring. During this cyclic process, the condensed water not only effectively promotes the heat exchange process of the outdoor heat exchanger 20, but also significantly reduces the energy consumption of the air conditioner in the refrigeration mode through the principle of evaporation and heat absorption, thereby improving the refrigeration energy efficiency of the entire system.

[0058] In an alternative embodiment, the diversion groove 120 includes a first groove section 121 and a second groove section 122. The first groove section 121 extends along the lateral direction of the chassis body 10, and the second groove section 122 extends along the front-rear direction of the chassis body 10 and communicates with the water collection tank 110 and the second groove section 122.

[0059] In the heating mode, the outdoor heat exchanger 20 of the integrated air conditioner 1 is used as an evaporator, which means that the outdoor heat exchanger 20 will generate condensed water like the indoor heat exchanger in the refrigeration mode. These condensed waters mainly come from the condensation of water vapor in the air on the surface of the outdoor heat exchanger 20.

[0060] Since the first groove section 121 extends along the lateral direction of the chassis body 10, it can widely cover the area below the outdoor heat exchanger 20 and effectively collect the condensed water dripping from the surface of the heat exchanger. The collected condensed water then flows along the first groove section 121 and is discharged outward, avoiding the accumulation and overflow of condensed water on the chassis 10.

[0061] In an alternative embodiment, the water collection tank 110 has one end close to the first groove section 121 and one end far from the first groove section 121. The first groove section 121 is communicated with the end of the water collection tank 110 close to itself through the second groove section 122.

[0062] The first trough section 121 communicates with one end of the water collecting trough 110 close to itself through the second trough section 122, ensuring that the condensed water can flow smoothly from the water collecting trough 110 into the diversion trough 120 without going through complex turning or bypassing flows. Due to this segmented and clearly - directed layout of the diversion trough 120, after the condensed water enters the diversion trough 120 from the water collecting trough 110, its flow path is significantly shortened. The distance that the condensed water needs to flow through is shorter, thereby reducing the flow resistance and flow time, and improving the discharge efficiency.

[0063] In an alternative embodiment, the water collecting trough 110 can be a rectangular trough and is tapered from top to bottom. That is, the water collecting trough 110 is wider at the top and narrower at the bottom.

[0064] When the outdoor fan 30 operates, the water - splashing ring continuously disturbs the condensed water in the water collecting trough 110. Due to the design of the water collecting trough 110 being wider at the top and narrower at the bottom, it provides sufficient shaking space for the condensed water. This means that even if the water - splashing ring generates a large centrifugal force during rotation, the condensed water will not be easily squeezed out of the water collecting trough 110 significantly, thus reducing the water - level fluctuation.

[0065] By maintaining a certain water level in the water collecting trough 110, the water - splashing ring can continuously and stably sprinkle the condensed water onto the outdoor heat exchanger 20. This stable water level helps to ensure that the condensed water can evenly cover the fins of the heat exchanger, improving the heat - exchange efficiency. At the same time, it also reduces the problems of the water - splashing ring idling due to too low water level or uneven sprinkling.

[0066] In an alternative embodiment, the ratio range of the lateral width of the first trough section 121 to the lateral width of the water collecting trough 110 can be 1:3 to 1:5. For example, 1:3, 1:4, 1:5, etc.

[0067] It can be understood that the intersection of the first trough section 121 and the water collecting trough 110 is the water outlet of the water collecting trough 110. By restricting the lateral width of the first trough section 121, it is possible to effectively avoid the water outlet of the water collecting trough 110 being designed too wide. The narrower water outlet helps to slow down the discharge speed of the condensed water, thereby maintaining the water - splashing water level in the water collecting trough 110 to a certain extent. This is crucial for ensuring that the water - splashing ring can work continuously and stably.

[0068] Although the width of the water outlet is restricted, a reasonable ratio design can still ensure that the accumulated water in the water collecting trough 110 can be discharged smoothly when it reaches a certain amount. This design reduces the risk of a sharp drop in the water level in the water collecting trough 110 due to too fast drainage, balancing the relationship between the drainage efficiency and the stability of the water - splashing water level.

[0069] The chassis body 10 is also provided with a drainage trough 130. The drainage trough 130 communicates with the diversion trough 120 and is used to discharge the condensed water collected by the diversion trough 120 out of the chassis body 10.

[0070] In the refrigeration mode, the surface temperature of the indoor heat exchanger (which is the evaporator at this time) is lower than the dew point temperature of the indoor air, causing water vapor in the air to condense into liquid water on the surface of the heat exchanger, that is, the indoor heat exchanger generates condensate. The generated condensate is collected into the water collection tank 110 through the drainage pipeline and is sprinkled onto the fins of the outdoor heat exchanger 20 by the water spraying ring (or called the spraying device) of the outdoor fan 30, which helps the outdoor heat exchanger 20 dissipate heat more effectively, improves the heat exchange efficiency, and thus reduces the energy consumption under the refrigeration condition. When the condensate in the water collection tank 110 exceeds a certain amount, the excess water will overflow to the diversion trough 120. One purpose of the diversion trough 120 is to guide these excess condensate flows into the drainage trough 130. The drainage trough 130 is the final link of the condensate drainage system and is responsible for safely and smoothly discharging the condensate from the chassis body 10 to maintain the dryness of the chassis 10 and prevent corrosion problems caused by water accumulation.

[0071] In the heating mode, the surface temperature of the outdoor heat exchanger 20 (which is the evaporator at this time) is lower than the dew point temperature of the outdoor air, causing water vapor in the air to condense into liquid water on the surface of the heat exchanger, that is, the outdoor heat exchanger 20 generates condensate. The diversion trough 120 is located below the outdoor heat exchanger 20, and its another purpose is to collect the condensate dripping from the outdoor heat exchanger 20 and guide the outflow direction of the condensate.

[0072] In an alternative embodiment, a drain port 131 is provided at the bottom of the drainage trough 130, and a drain valve 132 for opening and closing the drain port 131 is provided.

[0073] When it is necessary to drain the condensate, the drain valve 132 can be opened to allow the condensate to flow out through the drain port 131. When it is not necessary to drain water or it is necessary to stop draining water, the drain valve 132 can be closed to prevent the condensate from flowing out.

[0074] The design of the drain valve 132 enables the operator to flexibly control the drainage of the condensate according to the actual situation and requirements. For example, when it is necessary to maintain or clean the drainage system, the drain valve 132 can be temporarily closed to prevent the condensate from continuing to drain.

[0075] By precisely controlling the opening and closing of the drain valve 132, the energy-saving effect can be achieved to a certain extent. For example, in the case where the amount of condensate generated is small, the opening time of the drain valve 132 can be delayed to reduce unnecessary energy consumption. At the same time, timely draining of the condensate also helps to protect the equipment from the risk of corrosion and damage caused by water accumulation.

[0076] In an example, the drainage trough 130 can be located at one end of the diversion trough 120 away from the water collection tank 110 and extend along the front-rear direction of the chassis body 10.

[0077] By placing the drain trough 130 at one end of the diversion trough 120, direct conflicts with other components are avoided, enabling the entire drainage system to be compactly installed on the chassis body 10 and reducing unnecessary space waste. The drain trough 130 extending in the front-back direction of the chassis body 10 can maximize the utilization of the lengthwise space of the chassis 10, making the entire system more compact and efficient.

[0078] In addition, since the drain trough 130 is located at one end of the diversion trough 120 and extends in the front-back direction, lateral drainage can also be achieved, enabling maintenance personnel to more easily access and perform necessary inspections, cleaning, or replacement work, reducing the complexity and risk during maintenance.

[0079] In one example, the bottom surface of the water collecting trough 110 can be slightly higher than the bottom surface of the diversion trough 120.

[0080] In the cooling mode, the condensed water generated by the indoor heat exchanger can first enter the water collecting trough 110 and then flow into and be stored in the diversion trough 120. As the condensed water continuously increases and the water level rises, a certain water level height is also present in the water collecting trough 110 for the water spraying ring to sprinkle onto the outdoor heat exchanger 20. When drainage is required, since the bottom surface of the water collecting trough 110 is higher than the bottom surface of the diversion trough 120, the condensed water in the water collecting trough 110 can quickly flow into the diversion trough 120, avoiding problems that may be caused by excessive water accumulation in the water collecting trough 110.

[0081] In the heating mode, although the generation position of the condensed water shifts from the indoor heat exchanger to the outdoor heat exchanger 20, the designs of the water collecting trough 110 and the diversion trough 120 can still play an important role. When the condensed water droplets on the outdoor heat exchanger 20 fall into the water collecting trough 110, due to the bottom surface of the water collecting trough 110 being higher than the bottom surface of the diversion trough 120, these condensed waters can quickly flow into the diversion trough 120, avoiding the freezing phenomenon that may occur due to long-term retention in the water collecting trough 110 and effectively preventing damage caused by the fan blades hitting the ice cubes.

[0082] In one example, the bottom surface of the drain trough 130 can be slightly higher than the bottom surface of the diversion trough 120.

[0083] When the amount of condensed water is small, due to the bottom surface of the drain trough 130 being slightly higher than the bottom surface of the diversion trough 120, the condensed water will first accumulate in the diversion trough 120. In this way, the system does not need to frequently start draining.

[0084] In this embodiment, the bottom surface of the drain trough 130 can be at the same height as the bottom surface of the water collecting trough 110. When the water level height in the water collecting trough 110 rises, the water level height in the drain trough 130 will also rise accordingly. This method can improve the water storage capacity of the chassis body 10 and reduce the number of drainages.

[0085] The drain valve 132 can be a temperature control valve, which can automatically adjust the opening and closing state of the valve according to the set temperature, thereby controlling the discharge of condensate. For example, in the heating mode, when the water temperature in the drain tank 130 drops to -2°C, the drain valve 132 can be opened for drainage to prevent the condensate from freezing in the water collection tank 110.

[0086] The drain valve 132 can be installed along the front-back direction of the chassis body 10, thereby reducing the lateral width of the chassis body 10, improving the space utilization rate, and making each component more compact on the chassis body 10.

[0087] At this point, those skilled in the art should recognize that although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and determined to cover all these other variations or modifications.
