Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an integrated air conditioner. Background Art

[0002] Integrated air conditioners, also known as window air conditioners or through-the-wall air conditioners depending on their installation location, are widely used as efficient cooling devices in modern homes and commercial spaces. However, in actual operation, through-the-wall air conditioners have encountered some technical difficulties in the treatment and utilization of condensate.

[0003] Traditional window-type air conditioners typically have a rear panel that is the same length as the chassis, making a fully enclosed rear panel a reasonable option. This design effectively prevents outside air or moisture from entering the unit, ensuring that condensed water flows along a predetermined path and is discharged through a dedicated drainage channel. However, the unique structural characteristics of through-the-wall air conditioners make a fully enclosed rear panel a limiting factor.

[0004] In through-the-wall air conditioners, the outdoor and indoor sides are connected by a wall, severely restricting the machine's structure and spatial layout. This is particularly true for the rear baffle. If a fully enclosed design were to continue, condensed water, under high pressure, would flow through gaps into specific areas on either side of the chassis, unable to be effectively redirected back to the condenser for water pumping. This would not only result in insufficient water pumping to the condenser, impacting the energy efficiency and performance of the entire unit, but could also cause condensed water waste and environmental pollution.

[0005] To address this issue, the industry has conducted extensive research and experimentation. Currently, a common solution is to add a soaking pipe on the outside of the rear bulkhead, soaking the pipe with condensed water to improve energy efficiency. However, while this approach has achieved some success, it also comes with the issue of increased costs. Furthermore, the design and maintenance of the soaking pipe are relatively complex, placing an additional burden on users.

[0006] Therefore, how to effectively solve the problem of condensate treatment and utilization in through-the-wall air conditioners without increasing costs has become a technical problem that needs to be solved urgently in the industry. Utility Model Content

[0007] One purpose of the utility model is to maintain the water pumping volume of the water ring and improve the heat exchange efficiency of the outdoor heat exchanger.

[0008] Another purpose of the present invention is to utilize wind pressure to drive the condensed water to flow, so that the condensed water on the left and right sides of the rear partition naturally flows back to the bottom of the outdoor fan through the drainage channel.

[0009] In particular, the present invention provides an integrated air conditioner, comprising:

[0010] a bottom pan having a water collection area for collecting condensed water;

[0011] a rear baffle, disposed on a side of the chassis having the water collection area;

[0012] an outdoor fan disposed on the rear partition; and

[0013] an outdoor heat exchanger, disposed on the chassis and located behind the outdoor fan;

[0014] The outdoor fan has a water ring, which is used to splash condensed water below the outdoor fan onto the outdoor heat exchanger during the rotation of the outdoor fan.

[0015] A drainage channel is formed at the bottom of the rear partition, and the drainage channel is used to allow condensed water on the left and right sides of the rear partition to flow back to the bottom of the outdoor fan to make up for the water pumping amount of the water ring.

[0016] Optionally, the outdoor fan is configured to suck in outdoor air from the left and right sides of the rear partition and blow part of the sucked outdoor air backward through the outdoor heat exchanger;

[0017] The drainage channel is configured to extend along the front-to-rear direction of the rear baffle, so that the condensed water on the left and right sides of the rear baffle flows backward from the front end of the drainage channel along the flow direction of the airflow.

[0018] Optionally, the rear partition includes:

[0019] a partition body having a first mounting portion, wherein the outdoor fan is mounted in the first mounting portion; and

[0020] The motor bracket is located on the front side of the partition body and has a second installation portion. The motor for driving the outdoor fan to rotate is installed in the second installation portion.

[0021] Optionally, a supporting portion extending forward is formed at the lower end of the first mounting portion, a supporting portion extending downward is formed at the lower end of the second mounting portion, and the lower end of the supporting portion is supported on the supporting portion.

[0022] Optionally, at least one connecting portion extending outward is formed on a periphery of the second mounting portion, and one end of the connecting portion away from the second mounting portion is connected to the partition body.

[0023] Optionally, part of the bottom wall of the first mounting portion forms the top wall of the drainage channel.

[0024] Optionally, the ratio of the width of the drainage channel to the width of the partition body is in the range of 1:2 to 1:4.

[0025] Optionally, the partition body and the motor bracket are integrally formed.

[0026] Optionally, a water collecting trough is provided in the water collecting area, and the water collecting trough is located below the water ring and extends along the left and right directions of the chassis.

[0027] Optionally, a drainage hole is provided at one end of the water collecting tank, and a drainage valve is provided at the drainage hole.

[0028] This integrated air conditioner features an outdoor fan equipped with a water ring. As the fan rotates, the ring automatically splashes condensed water from below onto the outdoor heat exchanger, reusing the condensed water and enhancing the heat exchange efficiency of the outdoor heat exchanger. Drainage channels at the bottom of the rear baffle allow condensed water from the left and right sides of the rear baffle to flow back under the outdoor fan, effectively replenishing the water required by the water ring and ensuring its continued effective operation. Because the condensed water is effectively utilized to enhance heat exchange in the outdoor heat exchanger, the air conditioner's energy efficiency is significantly improved.

[0029] Furthermore, the integrated air conditioner of the present invention features a drainage channel extending along the front-to-back direction of the rear baffle. The outdoor fan draws in outdoor air from both sides of the rear baffle and blows this air backward through the outdoor heat exchanger. This allows the wind pressure generated by the outdoor fan to direct condensed water from the left and right sides of the rear baffle, following the direction of the airflow and flowing backward from the front of the drainage channel. This method of utilizing wind pressure to drive the natural flow of condensed water eliminates the need for additional power or pumping devices, achieving automatic condensate return, reducing both energy consumption and operating costs.

[0044] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0045] The utility model provides an integrated air conditioner 1, which generally includes: a chassis 10, an indoor heat exchanger, an indoor fan, an outdoor heat exchanger 40 and an outdoor fan 30, wherein the indoor heat exchanger and the indoor fan are arranged in the front area of ​​the chassis 10, and the outdoor heat exchanger 40 and the outdoor fan 30 are arranged in the rear area of ​​the chassis 10.

[0046] The chassis 10 serves as the supporting base of the entire air conditioner 1 and is mainly used to bear the weight of each component and vibration during operation. The indoor heat exchanger, indoor fan, outdoor fan 30 and outdoor heat exchanger 40 are arranged in sequence from front to back on the chassis 10.

[0047] The indoor heat exchanger is primarily used to absorb or release heat from the indoor air. In cooling mode, it acts as an evaporator, absorbing heat from the indoor air to cool it down. In heating mode, it acts as a condenser, releasing heat to the indoor air to warm it up.

[0048] Indoor fans are primarily used to promote indoor air circulation, blowing air through the indoor heat exchanger to accelerate the heat exchange process. In cooling mode, the indoor fan blows cooled air into the room, lowering the room temperature; in heating mode, the indoor fan blows heated air into the room, raising the room temperature.

[0049] The outdoor heat exchanger 40 is primarily used to absorb or release heat from the outdoor air. In cooling mode, the outdoor heat exchanger 40 operates as a condenser, releasing heat absorbed from the indoor air to the outdoor air. In heating mode, the outdoor heat exchanger 40 operates as an evaporator, absorbing heat from the outdoor air.

[0050] The outdoor fan 30 is primarily used to promote outdoor air circulation, blowing outdoor air through the outdoor heat exchanger 40 to accelerate the heat exchange process. In cooling mode, the outdoor fan 30 dissipates heated air outdoors; in heating mode, the outdoor fan 30 helps the outdoor heat exchanger 40 absorb heat from the outdoor air.

Figure 2 is a schematic top view of an integrated air conditioner 1 according to an embodiment of the present utility model.

Figure 5 2 is a schematic structural diagram of the rear partition 20 from a first perspective according to an embodiment of the present invention. Figure 6 It is a schematic structural diagram of the rear partition 20 at a first viewing angle according to an embodiment of the present invention.

[0052] It is worth mentioning that the integrated air conditioner 1 of the present invention can be flexibly installed in a window position as a window air conditioner 1, and can also be conveniently set in a wall hole to use as a through-the-wall air conditioner 1. The illustrations of the present invention will focus on the rear area of ​​the chassis 10. At the same time, in order to maintain the focus of the illustration, the relevant illustrations of the indoor heat exchanger and indoor fan will not be included in this presentation.

[0053] like Figures 1 to 6 As shown, the integrated air conditioner 1 of the present invention may include: a chassis 10 , a rear partition 20 , an outdoor fan 30 and an outdoor heat exchanger 40 .

[0054] The chassis 10 has a water collection area 110 for collecting condensed water. The rear baffle 20 is located on one side of the chassis 10 with the water collection area 110. The outdoor fan 30 is mounted on the rear baffle 20. The outdoor heat exchanger 40 is also mounted on the chassis 10 and located behind the outdoor fan 30. The outdoor fan 30 has a water ring 310, which is used to splash condensed water from below the outdoor fan 30 onto the outdoor heat exchanger 40 during rotation. A drainage channel 230 is formed at the bottom of the rear baffle 20. This channel 230 allows condensed water from the left and right sides of the rear baffle 20 to flow back to the bottom of the outdoor fan 30, thereby compensating for the amount of water pumped by the water ring 310.

[0055] The integrated air conditioner 1 of the present invention features an outdoor fan 30 equipped with a water ring 310. As the outdoor fan 30 rotates, the water ring 310 automatically splashes condensed water from below onto the outdoor heat exchanger 40, reusing the condensed water and enhancing the heat exchange efficiency of the outdoor heat exchanger 40. Drainage channels 230 at the bottom of the rear baffle 20 allow condensed water from the left and right sides of the rear baffle 20 to flow back under the outdoor fan 30, effectively replenishing the water required by the water ring 310 and ensuring its continued effective operation. Because the condensed water is effectively utilized to enhance heat exchange in the outdoor heat exchanger 40, the energy efficiency of the air conditioner 1 is significantly improved.

[0056] In an optional embodiment, the outdoor fan 30 is configured to draw outdoor air from both left and right sides of the rear partition 20 and blow part of the drawn outdoor air rearward through the outdoor heat exchanger 40 .

[0057] The outdoor fan 30 may be an axial flow fan. Figure 2 and Figure 3 The operation effects of the outdoor fan 30 are shown respectively. Figure 2 and Figure 3 In the figure, it can be clearly seen that outdoor air is drawn in from the left and right sides of the rear partition 20. The drawn in air is divided into two flows: one part directly passes through the outdoor heat exchanger 40 and is blown out backwards; the other part, blocked by the outdoor heat exchanger 40, is diverted along the bottom gap of the outdoor heat exchanger 40 and discharged to both sides.

[0058] In short, in order to achieve the goal of efficient air circulation and heat exchange, this embodiment arranges the outdoor air inlet of the integrated air conditioner 1 on the left and right sides of the rear partition 20, arranges the outdoor air outlet in the middle position of the rear partition 20, and the outdoor heat exchanger 40 is built into the outdoor air outlet.

[0059] It's worth noting that when some outdoor air is blocked by the outdoor heat exchanger 40 and flows to the left and right along the gaps at its bottom, this flow also causes condensed water inside the rear baffle 20 to move to the left and right. This flow pattern causes the water level below the water ring 310 to drop significantly, causing the water ring 310 to under-pump or even run idle. This significantly negatively impacts the heat exchange efficiency of the outdoor heat exchanger 40 because the amount of condensed water participating in the heat exchange is reduced.

[0060] In addition, when the water ring 310 rotates with the outdoor fan 30, the condensed water below it will be driven and tend to deviate to one side of the rotation direction. This phenomenon further aggravates the problem of insufficient water in the water ring 310.

[0061] To address this issue, in this embodiment, the drainage channel 230 is configured to extend along the front-to-back direction of the rear baffle 20. This ensures that condensed water on the left and right sides of the rear baffle 20 follows the natural flow of air, flowing smoothly from the front to the rear of the drainage channel 230, thereby compensating for the insufficient condensed water supply below the water ring 310.

[0062] This embodiment utilizes the wind pressure effect generated by the outdoor fan 30 to automatically guide the condensed water back to the outside of the room, without requiring any additional power or pumping devices. This innovative wind pressure-driven condensed water flow not only significantly reduces energy consumption but also effectively lowers the operating costs of the air conditioner 1, demonstrating excellent energy-saving and environmentally friendly features.

[0063] In an optional embodiment, the rear partition 20 may include a partition body 210 and a motor 50 bracket 220, wherein the partition body 210 serves as the main structural part of the rear partition 20, and the partition body 210 has a first mounting portion 211, and the outdoor fan 30 is mounted in the first mounting portion 211. The motor 50 bracket 220 is located on the front side of the partition body 210, and the motor 50 bracket 220 has a second mounting portion 221, and the motor 50 for driving the outdoor fan 30 to rotate is mounted in the second mounting portion 221.

[0064] By mounting the motor 50 on the motor bracket 220 and connecting it to the outdoor fan 30 through a precise mounting arrangement, the transmission efficiency and stability between the motor 50 and the fan are ensured. This design helps reduce the risk of system downtime due to motor 50 or fan failure, thereby enhancing the reliability and stability of the entire air conditioning system.

[0065] It's worth noting that the motor 50 can also be designed to simultaneously drive the indoor fan. That is, a single motor 50 can simultaneously drive both the indoor fan and the outdoor fan 30. This reduces energy consumption. Compared to using two separate motors 50 to drive each fan, this design significantly reduces overall energy consumption and improves energy efficiency.

[0066] Furthermore, the use of a single motor 50 to drive two fans simplifies the internal structure of the air conditioner 1. This not only reduces the number of components and complexity, but also lowers manufacturing costs and maintenance. Furthermore, the more compact structure also helps improve the overall performance and stability of the air conditioner 1.

[0067] In an optional embodiment, the lower end of the first mounting portion 211 may be formed with a supporting portion 212 extending forward, and at the same time, the lower end of the second mounting portion 221 may be formed with a supporting portion 222 extending downward, and the lower end of the supporting portion 222 is supported on the supporting portion 212.

[0068] The support structure effectively supports the second mounting portion 221 and the motor 50 thereon. This front-to-back support structure not only enhances the stability of the motor 50's installation but also helps reduce vibration and noise generated by the motor 50 during operation, thereby improving the overall stability and reliability of the system. Furthermore, the support portion 222 cooperates with the supporting portion 212 to form a stable support system, ensuring the stability and safety of the motor 50 during installation and use.

[0069] In an optional embodiment, at least one connecting portion 223 extending outward is formed on the periphery of the second mounting portion 221 , and one end of the connecting portion 223 away from the second mounting portion 221 is connected to the partition body 210 .

[0070] The provision of the connection portion 223 simplifies the connection between the motor 50 bracket 220 and the partition body 210, making it easier to connect the motor 50 bracket 220 to the partition body 210. At the same time, the outward extension design of the connection portion 223 also provides more operating space during the installation process of the motor 50, making the installation more convenient for the installer and improving installation efficiency.

[0071] In this embodiment, the partition body 210 (including the first mounting portion 211 and the supporting portion 212 ) and the motor 50 bracket 220 (including the second mounting portion 221 , the supporting portion 222 and the connecting portion 223 ) are integrally formed.

[0072] The one-piece design makes the connection between the partition body 210 and the motor 50 bracket 220 more secure, avoiding structural problems caused by loose or failed connectors. This design enhances the strength and rigidity of the overall structure, improving the stability and durability of the air conditioner 1 during operation.

[0073] In addition, one-piece molding reduces the number of parts and assembly steps, thereby simplifying the manufacturing process and reducing production costs, while also reducing quality problems and failure rates caused by improper assembly.

[0074] In an optional embodiment, a portion of the bottom wall of the first mounting portion 211 forms the top wall of the drainage channel 230 .

[0075] When the rear bulkhead 20 is mounted on the chassis 10, the lower edge of the bulkhead body 210 rests on the upper surface of the chassis 10. A portion of the bottom wall of the first mounting portion 211 cleverly serves as the top wall of the drainage channel 230, while the left and right sidewalls of the drainage channel 230 support the top wall. This design not only ensures the stability and durability of the drainage channel 230 but also effectively enhances the structural strength of the first mounting portion 211. This mutual structural support ensures that the rear bulkhead 20 maintains excellent stability and reliability despite various external forces and vibrations.

[0076] In an optional embodiment, the ratio of the width of the drainage channel 230 to the width of the partition body 210 ranges from 1:2 to 1:4, for example, 1:2, 1:3, 1:4, etc. In other words, the width of the drainage channel 230 should not be too narrow or too wide. A narrow width may slow the return flow of condensed water, while a wide width may affect the support stability of the rear partition 20 on the chassis 10.

[0077] In an optional embodiment, a water collecting tank 120 is provided in the water collecting area 110 . The water collecting tank 120 is located below the water ring 310 and extends in the left-right direction of the chassis 10 .

[0078] The sump 120 effectively collects and concentrates condensed water dripping from the indoor heat exchanger or other components. Because the sump 120 is located below the water ring 310, condensed water can flow smoothly into it, preventing it from flowing and accumulating on the chassis 10, thereby keeping the chassis 10 clean and dry.

[0079] In an optional embodiment, a drainage hole 130 may be provided at one end of the water collection tank 120 , and a drainage valve 140 may be provided at the drainage hole 130 .

[0080] Because the sump 120 extends along the left and right sides of the chassis 10, this layout helps the condensed water to be evenly distributed within the sump 120 and flow smoothly toward the drain holes 130. This not only improves drainage efficiency and reduces drainage time, but also reduces the risk of corrosion and bacterial growth on the chassis 10 caused by the accumulation of condensed water.

[0081] In addition, timely collection and discharge of condensed water helps to maintain a dry environment inside the air conditioner 1, which is crucial for maintaining the performance of the air conditioner 1 and extending its service life.

[0082] The addition of drain valve 140 makes the drainage process controllable. Users or the system can flexibly open or close drain valve 140 based on actual needs, such as the amount of condensed water accumulated or external environmental conditions, to precisely control the amount of water drained. This not only helps avoid wasteful use of resources due to excessive drainage, but also allows for the rapid removal of accumulated water when necessary, preventing damage to the equipment caused by excessive water accumulation within the chassis 10.

[0083] The design of the drain valve 140 facilitates the user to perform regular maintenance and cleaning. By simply operating the drain valve 140, the user can easily drain the residual water in the sump 120, reduce the chances of bacterial growth and odor generation, and maintain the sanitary condition inside the air conditioner 1.

[0084] The amount of condensed water generated varies in different regions or seasons due to differences in temperature and humidity. The adjustable function of the drain valve 140 enables the air conditioner 1 to better adapt to these changes, maintaining optimal drainage efficiency and operating conditions whether in the high humidity of summer or the relatively dry winter.

[0085] By discharging condensed water in a timely manner, the drain valve 140 helps prevent potential faults such as short circuits and corrosion caused by water accumulation, thereby extending the service life of the air conditioner 1 and reducing maintenance costs.

[0086] Drain valve 140 can be a temperature-controlled valve that automatically adjusts its opening and closing state based on a set temperature, thereby controlling the discharge of condensed water. For example, in heating mode, when the water temperature in sump 120 drops to -2°C, drain valve 140 can be opened to drain the water, preventing condensed water from freezing in sump 120.

[0087] The drain valve 140 can be installed along the front-to-back direction of the chassis 10 , thereby reducing the lateral width of the chassis 10 , improving space utilization, and making the various components more compact on the chassis 10 .

[0088] According to any one of the above optional embodiments or a combination of multiple optional embodiments, the embodiments of the present utility model can achieve the following beneficial effects:

[0089] The integrated air conditioner 1 of the present invention features an outdoor fan 30 equipped with a water ring 310. As the outdoor fan 30 rotates, the water ring 310 automatically splashes condensed water from below onto the outdoor heat exchanger 40, reusing the condensed water and enhancing the heat exchange efficiency of the outdoor heat exchanger 40. Drainage channels 230 at the bottom of the rear baffle 20 allow condensed water from the left and right sides of the rear baffle 20 to flow back under the outdoor fan 30, effectively replenishing the water required by the water ring 310 and ensuring its continued effective operation. Because the condensed water is effectively utilized to enhance heat exchange in the outdoor heat exchanger 40, the energy efficiency of the air conditioner 1 is significantly improved.

[0090] Furthermore, the integrated air conditioner 1 of the present invention has a drainage channel 230 extending along the front-to-back direction of the rear partition 20. The outdoor fan 30 draws in outdoor air from both sides of the rear partition 20 and blows this air backward through the outdoor heat exchanger 40. This allows the wind pressure generated by the outdoor fan 30 to cause condensed water on both sides of the rear partition 20 to flow backward from the front end of the drainage channel 230, following the direction of the airflow. This method of using wind pressure to drive the natural flow of condensed water eliminates the need for additional power or pumping devices, achieving automatic condensed water recirculation, reducing energy consumption and lowering operating costs.

[0091] 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 consistent with the principles of the present invention can be directly determined or deduced from the contents disclosed herein without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
