Description

Technical Field

[0001] This invention relates to the technical field of condensate drainage, and more particularly to an air conditioner outdoor unit chassis and the air conditioner formed therefrom. Background Technology

[0002] The drain outlet diameter of existing household split-type air conditioners is relatively small. When used in harsh outdoor environments, condensate produced on the outdoor heating side of the air conditioner can easily freeze and become blocked due to dirt or delayed drainage. Once blocked, condensate accumulates in the air conditioner's chassis, where it can easily freeze over a large area at low temperatures. When the ice layer reaches a certain thickness, it will severely affect the condenser's heat exchange efficiency. In severe cases, it can even cause the outdoor unit's fan blades to become stuck or broken by the ice, posing a certain danger.

[0003] In existing technology, the size of the drain outlet in the outdoor unit chassis is constant. Regardless of the amount of condensate produced during air conditioner operation, the condensate is discharged at a constant rate. When there is a lot of condensate, it may accumulate because it cannot be discharged in time, which may lead to the risk of condensate freezing.

[0004] Meanwhile, existing technologies primarily rely on mounting electric heating elements or wires on the chassis to defrost frozen condensate. Heating is activated during heating to perform the defrosting operation. However, once activated, these heating elements or wires continuously heat without adjusting their power based on condensate drainage. In reality, when the external temperature is above 0°C, the chassis is unlikely to freeze, eliminating the need for electric heating; this results in energy waste. Summary of the Invention

[0005] To overcome the problems existing in related technologies, one of the objectives of this invention is to provide an air conditioner outdoor unit chassis that allows for adjustment of the condensate drain outlet size via a liftable drip tray, ensuring timely and effective condensate drainage.

[0006] An air conditioner outdoor unit chassis, comprising:

[0007] The drainage opening is located in the chassis of the outdoor unit;

[0008] A water receiving tray located below the drainage gap; the water receiving tray is provided with a water outlet;

[0009] The water receiving tray is slidably connected to the outdoor unit chassis via a sliding member, and the sliding member can drive the water receiving tray to rise and fall below the drainage gap;

[0010] When the condensate in the drip tray is less than or equal to the threshold, the sliding member drives the drip tray to slide to the position where it abuts against the chassis of the outdoor unit; when the condensate in the drip tray is greater than the threshold, the sliding member drives the drip tray to descend.

[0011] If the amount of condensate flowing into the drip tray is small, the sliding element moves the drip tray to a position where it abuts against the outdoor unit chassis. At this point, the condensate flows out through the outlet in the drip tray. Because the amount of condensate is small, it will not accumulate or freeze in the drip tray or the outdoor unit chassis. The contact between the drip tray and the outdoor unit chassis ensures a seamless connection, preventing impurities or small animals from entering the outdoor unit chassis. When there is a large amount of condensate, exceeding a threshold (which can be a preset weight or volume value), the condensate will not drain quickly enough if it only flows out through the outlet, causing it to accumulate in the outdoor unit chassis. Therefore, the sliding element moves the drip tray away from the outdoor unit chassis. At this point, the condensate can flow out through the gap between the outdoor unit chassis and the drip tray, accelerating drainage and preventing accumulation in the drip tray or the outdoor unit chassis. This prevents accumulated condensate from freezing and affecting the heat exchange efficiency of the condenser.

[0012] Furthermore, the sliding component includes guide posts located at both ends of the water receiving tray, the top of the guide posts being fixedly connected to the outdoor unit chassis; the guide posts pass through both ends of the water receiving tray and are slidably connected to the water receiving tray.

[0013] In this application, there are two guide columns, each fixed to the bottom of the outdoor unit chassis. A water receiving chamber is located in the middle of the water receiving tray, and protrusions extending above the water receiving chamber are located at both ends. Guide holes are provided on the protrusions, with the inner diameter of the guide holes slightly larger than the outer diameter of the guide columns. The top of the guide columns is fixedly connected to the outdoor unit chassis; the bottom of the guide columns passes through the guide holes and is located below the water receiving tray. In this application, the guide columns provide guidance for the sliding of the water receiving tray. Simply setting the guide columns vertically ensures that the water receiving tray can smoothly rise and fall along the guide columns.

[0014] Furthermore, the sliding member also includes a spring nested on the guide post, the top of the spring abutting against the water receiving tray, and the bottom of the spring abutting against the bottom of the guide post.

[0015] In this application, the top of the spring abuts against the protrusions at both ends of the drip tray, allowing the drip tray to slide along the guide post under gravity. When the volume of condensate stored in the drip tray varies, the gravity of the drip tray and the condensate inside will cause the drip tray to slide down the guide post. In actual operation, simply setting the guide post vertically is sufficient; no external drive component is needed. Gravity will then drive the drip tray to rise and fall, simplifying the condensate drainage structure, making it easy to operate, and eliminating the need for additional power drive components.

[0016] Furthermore, a nut is provided at the bottom end of the guide post, and the nut is threadedly connected to the bottom of the guide post. A washer is provided between the nut and the spring.

[0017] The bottom of the guide post in this application has an external thread, and the nut has a matching internal thread. The nut and the bottom of the guide post are connected by threads, and the bottom of the spring abuts against the top of the nut through a washer. The washer is provided to protect the nut and form a buffer layer between the spring and the nut. When the nut rotates up and down, it can cause the bottom position of the spring to change. The top of the spring always abuts against the water receiving tray. When the bottom position changes, the elastic force of the spring against the water receiving tray will change.

[0018] For example, when the nut moves the bottom of the spring to a higher position, meaning the bottom of the spring is closer to the drip tray, the spring is compressed more, resulting in a greater elastic force on the drip tray. Only when the weight of the drip tray and the condensate inside is greater can this force offset the spring's elastic force, causing the drip tray to descend. Conversely, when the nut moves the bottom of the spring to a lower position, meaning the bottom of the spring is farther from the drip tray, the spring is compressed less, resulting in a smaller elastic force on the drip tray. The weight of the drip tray and the condensate inside is also less, thus offsetting the spring's elastic force and causing the drip tray to descend. Therefore, different thresholds can be set by adjusting the position of the nut to achieve different standards for the raising and lowering of the drip tray under different conditions.

[0019] Furthermore, a driving component is provided on the side of the water receiving tray, and the output end of the driving component is connected to the water receiving tray; a water level detector is provided in the water receiving tray.

[0020] In this embodiment, a cylinder or other driving component is installed on the side of the water receiving pan, and a water level sensor is installed in the water receiving chamber. The height of the water level sensor is observed to determine whether the condensate in the water receiving chamber has reached a threshold. If the threshold is reached, the driving component operates, causing the water receiving pan to descend. The driving component and the water level sensor can be connected in communication, or both can be connected to the controller of a corresponding appliance such as an air conditioner, enabling interaction between the water level sensor and the driving component.

[0021] Furthermore, it also includes an adjusting resistor and heating lines installed in the outdoor unit chassis, wherein the adjusting resistor and heating lines are connected in series to both ends of the power supply to form a heating path; the heating lines are distributed in the heating chassis.

[0022] In this application, an adjustable resistor is connected in series with the heating pipe, and the resistance value of the adjustable resistor can be varied. When it is necessary to enhance the heating effect of the heating pipe, the resistance value of the adjustable resistor can be decreased. The resistance in the series circuit of the adjustable resistor and the heating pipe decreases, the current increases, and the heating power of the heating pipe increases, meaning the heat generated by the heating pipe increases. When it is necessary to weaken the heating effect of the heating pipe, the resistance value of the adjustable resistor can be increased. The resistance in the series circuit of the adjustable resistor and the heating pipe increases, the current decreases, and the heating power of the heating pipe decreases, meaning the heat generated by the heating pipe decreases.

[0023] Furthermore, the regulating resistor includes a guide rod and an adjusting element, wherein the guide rod is a conductor; the first end of the heating pipe is fixedly connected to the guide rod, and the second end of the heating pipe can slide along the guide rod under the action of the adjusting element; when the condensate in the water receiving pan is less than or equal to a threshold, the adjusting element drives the second end of the heating pipe to slide in the guide rod to a first position; when the condensate in the water receiving pan is greater than the threshold, the adjusting element drives the second end of the heating pipe to slide in the guide rod to a second position; and the heating power of the heating path corresponding to the first position is less than the heating power of the heating path corresponding to the second position.

[0024] This application determines the portion of the guide rod that enters the heating path by adjusting the position of the second end of the heating pipe. The position of the first end of the heating pipe in the guide rod is fixed. The greater the distance between the second end of the heating pipe and the first end of the heating wire, the greater the resistance of the adjustable resistor entering the heating path. When the condensate in the drip tray is less than or equal to the threshold, it indicates that the drip chamber can drain normally and there is no ice formation in the drip chamber. The heating pipe can then heat at a lower power.

[0025] When the condensate in the drip tray exceeds the threshold, it indicates that the drip chamber may freeze, causing blockage of the outlet. At this time, the adjusting component moves the second end of the heating pipe, making the resistance of the adjusting resistor connected in series into the heating path smaller, thereby allowing the heating pipe to heat with higher power and preventing the condensate in the outdoor unit chassis from freezing.

[0026] Furthermore, the adjusting component includes a slide rod, both the guide rod and the slide rod are vertically arranged, the second end of the heating pipe abuts against the upper end of the guide rod, and the second end of the heating pipe is fixed to one end of the slide rod by a fixing bracket;

[0027] The other end of the slide bar is fixedly connected to the water receiving tray; the raising and lowering of the water receiving tray can drive the slide bar to rise and fall synchronously.

[0028] This application uses a slider to link the resistance value of the regulating resistor in the heating circuit with the position of the water tray. If the water tray is likely to freeze, i.e., the water tray is separated from the outdoor unit chassis, the resistance value of the regulating resistor in the heating circuit will decrease. If the water tray is not likely to freeze, i.e., the water tray is in contact with the outdoor unit chassis, the resistance value of the regulating resistor in the heating circuit will increase.

[0029] Furthermore, when the condensate in the water tray is less than or equal to the threshold, the sliding member drives the water tray to slide to the position where it abuts against the chassis of the outdoor unit, and the sliding rod drives the second end of the heating pipe to move to the upper end of the guide rod; when the condensate in the water tray is greater than the threshold, the sliding member drives the water tray to descend, and the sliding rod drives the second end of the heating pipe to move to the lower end of the guide rod.

[0030] This embodiment can determine whether the water tray is frozen based on its position. The position of the water tray is linked to the resistance value of the adjusting resistor in the heating circuit through a slide rod, thereby realizing intelligent automatic adjustment of the heating pipeline power and avoiding energy waste in the heating pipeline.

[0031] A second objective of this invention is to provide an air conditioner, including an outdoor unit chassis as described above. The liftable drip tray allows for timely and effective drainage of condensate, preventing its accumulation in the outdoor unit chassis and preventing it from freezing. This improves condensate drainage efficiency, ensures the heat exchange efficiency of the condenser, and enhances the stability of the air conditioner's operation.

[0032] The beneficial effects of this invention are as follows:

[0033] In this application, the outdoor unit chassis of the air conditioner includes a drain notch located within the chassis. A water collection tray is positioned below the drain notch, and the water collection tray has a drain outlet. Condensate from the outdoor unit flows through the drain notch into the water collection tray. The water collection tray is slidably connected to the outdoor unit chassis via a sliding member, which allows the water collection tray to move up and down below the drain notch. If the amount of condensate flowing into the water collection tray is small, the sliding member moves the water collection tray to a position where it abuts against the outdoor unit chassis. At this point, the condensate flows out through the drain outlet in the water collection tray. Because the amount of condensate is small, it does not accumulate or freeze in the water collection tray or the outdoor unit chassis. The contact between the water collection tray and the outdoor unit chassis ensures a seamless connection, preventing impurities or small animals from entering the outdoor unit chassis. When there is a large amount of condensate, and the amount of condensate flowing into the drip tray exceeds a threshold (which can be a preset weight or volume value), the condensate will not drain in time if it is only discharged through the outlet. This will cause the condensate to accumulate in the outdoor unit chassis. Therefore, the sliding component moves the drip tray down to a position away from the outdoor unit chassis. At this point, the condensate can flow out through the gap between the outdoor unit chassis and the drip tray, which can accelerate the drainage of condensate and prevent it from accumulating in the drip tray or the outdoor unit chassis. This will also prevent the accumulated condensate from freezing and affecting the heat exchange effect of the condenser.

[0034] The present invention also provides an air conditioner including the above-mentioned outdoor unit chassis, which, through a liftable water tray, enables timely and effective discharge of condensate, preventing condensate from accumulating in the outdoor unit chassis and preventing the accumulated condensate from freezing in the outdoor unit chassis, thereby improving the condensate discharge efficiency, ensuring the heat exchange efficiency of the condenser, and improving the stability of air conditioner operation.

[0046] Example 1

[0047] like Figures 1-6 As shown, the present application provides an air conditioner outdoor unit chassis, comprising:

[0048] The drainage opening is located in the outdoor unit chassis 1;

[0049] A water receiving tray 2 located below the drainage gap; the water receiving tray 2 is provided with a water outlet 22;

[0050] The water receiving tray 2 is slidably connected to the outdoor unit chassis 1 via a sliding member, and the sliding member can drive the water receiving tray 2 to rise and fall below the drainage gap;

[0051] When the condensate in the drip tray 2 is less than or equal to the threshold, the sliding member drives the drip tray 2 to slide to the position where it abuts against the outdoor unit chassis 1; when the condensate in the drip tray 2 is greater than the threshold, the sliding member drives the drip tray 2 to descend.

[0052] In this application, the sliding component can drive the water receiving tray 2 to rise and fall below the drain gap. Specifically, since the water receiving tray 2 is used to collect condensate, it is not suitable to be set above the outdoor unit chassis 1. The highest position it can rise and fall is the position where it abuts against the outdoor unit chassis 1. When the water receiving tray 2 abuts against the outdoor unit chassis 1, the condensate can only be discharged through the outlet 22 in the water receiving tray 2.

[0053] In this application, the distance that the sliding member drives the water receiving tray 2 to descend can be set to a maximum value. That is, the lowest position of the water receiving tray 2 can be set according to the size of the water receiving tray 2, etc. In actual operation, the sliding member can drive the water receiving tray 2 to slide up and down between the lowest position and the outdoor unit chassis 1.

[0054] The upper surface of the water receiving tray 2 of this application is provided with a water receiving chamber 23, which refers to the concave space located in the center of the water receiving tray 2. A water outlet 22 is provided at the bottom of the water receiving chamber 23. After the condensate enters the water receiving chamber 23, it flows out from the water outlet 22 at the bottom.

[0055] In this application, the outdoor unit chassis 1 of the air conditioner includes a drainage notch located in the outdoor unit chassis 1. A water receiving tray 2 is provided below the drainage notch, and a water outlet 22 is provided in the water receiving tray 2. Condensate from the outdoor unit reaches the water receiving tray 2 through the drainage notch. The water receiving tray 2 is slidably connected to the outdoor unit chassis 1 by a sliding member. The sliding member can drive the water receiving tray 2 to rise and fall below the drainage notch. If the amount of condensate flowing into the water receiving tray 2 is small, the sliding member drives the water receiving tray 2 to slide to a position where it abuts against the outdoor unit chassis 1. At this time, the condensate flows out through the water outlet 22 in the water receiving tray 2. Since the amount of condensate is small, it will not cause condensate to accumulate and freeze in the water receiving tray 2 or the outdoor unit chassis 1. At this time, the water receiving tray 2 and the outdoor unit chassis 1 abut against each other, which can ensure that there is no gap between the outdoor unit chassis 1 and the water receiving tray 2. The two are connected as one, preventing impurities or small animals from entering the outdoor unit chassis 1. When there is a lot of condensate, and the amount of condensate flowing into the drip tray 2 exceeds a threshold (which can be a preset weight or volume value), the condensate will not drain in time if it is only discharged through the outlet 22. This will cause the condensate to accumulate in the outdoor unit chassis 1. Therefore, the sliding part drives the drip tray 2 to a position away from the outdoor unit chassis 1. At this time, the condensate can flow out through the gap between the outdoor unit chassis 1 and the drip tray 2. This can accelerate the discharge of condensate and prevent the condensate from accumulating in the drip tray 2 or the outdoor unit chassis 1, thus preventing the accumulated condensate from freezing and affecting the heat exchange effect of the condenser.

[0056] Example 2

[0057] like Figures 1-6 As shown, the present application provides an air conditioner outdoor unit chassis, comprising:

[0058] The drainage opening is located in the outdoor unit chassis 1;

[0059] A water receiving tray 2 located below the drainage gap; the water receiving tray 2 is provided with a water outlet 22;

[0060] The water receiving tray 2 is slidably connected to the outdoor unit chassis 1 via a sliding member, and the sliding member can drive the water receiving tray 2 to rise and fall below the drainage gap;

[0061] When the condensate in the drip tray 2 is less than or equal to the threshold, the sliding member drives the drip tray 2 to slide to the position where it abuts against the outdoor unit chassis 1; when the condensate in the drip tray 2 is greater than the threshold, the sliding member drives the drip tray 2 to descend.

[0062] Furthermore, the sliding component of this application includes guide posts 12 located at both ends of the water receiving tray 2, the top end of the guide post 12 being fixedly connected to the outdoor unit chassis 1; the guide post 12 passes through both ends of the water receiving tray 2 and is slidably connected to the water receiving tray 2.

[0063] In this application, there are two guide pillars 12, which are fixed to the bottom of the outdoor unit chassis 1. A water receiving chamber 23 is provided in the middle of the water receiving tray 2, and protrusions extending above the water receiving chamber 23 are provided at both ends. Guide holes 21 are provided on the protrusions, with the inner diameter of the guide holes 21 slightly larger than the outer diameter of the guide pillars 12. The top of the guide pillar 12 is fixedly connected to the outdoor unit chassis 1; the bottom of the guide pillar 12 passes through the guide holes 21 and is located below the water receiving tray 2. In this application, the guide pillars 12 provide guidance for the sliding of the water receiving tray 2. Simply setting the guide pillars 12 vertically ensures that the water receiving tray 2 can smoothly rise and fall along the guide pillars 12.

[0064] Furthermore, the sliding component of this application also includes a spring 3 nested on the guide post 12, the top end of the spring 3 abutting against the water receiving tray 2, and the bottom end of the spring 3 abutting against the bottom of the guide post 12.

[0065] In this application, the top of the spring 3 abuts against the protrusions at both ends of the drip tray 2, allowing the drip tray 2 to slide along the guide post 12 under gravity. When the volume of condensate stored in the drip tray 2 varies, the gravity of the drip tray 2 and the condensate inside will cause the drip tray 2 to slide down along the guide post 12. In actual operation, simply setting the guide post 12 vertically is sufficient; no external drive is needed. Gravity will then drive the drip tray 2 to rise and fall, simplifying the condensate drainage structure, making it easy to operate, and eliminating the need for additional power drive components.

[0066] Furthermore, a nut 4 is provided at the bottom end of the guide post 12, and the nut 4 is connected to the bottom of the guide post 12 by a thread 121. A washer is provided between the nut 4 and the spring 3.

[0067] The bottom of the guide post 12 of this application is provided with an external thread, and the nut 4 is provided with a matching internal thread. The bottom of the nut 4 and the guide post 12 are connected by thread 121. The bottom of the spring 3 abuts against the top of the nut 4 through a washer. The washer is provided to protect the nut 4 and form a buffer layer between the spring 3 and the nut 4. When the nut 4 rotates up and down, it can cause the bottom position of the spring 3 to change. The top of the spring 3 always abuts against the water receiving tray 2. When the bottom position changes, the elastic force of the spring 3 against the water receiving tray 2 will change.

[0068] For example, when the nut 4 drives the bottom of the spring 3 to a higher position, meaning the bottom of the spring 3 is closer to the drip tray 2, the spring 3 is compressed more, resulting in a greater elastic force on the drip tray 2. Only when the weight of the drip tray 2 and the condensate inside it is greater can it offset the elastic force of the spring 3, causing the drip tray 2 to descend. Conversely, when the nut 4 drives the bottom of the spring 3 to a lower position, meaning the bottom of the spring 3 is farther from the drip tray 2, the spring 3 is compressed less, resulting in a smaller elastic force on the drip tray 2. The weight of the drip tray 2 and the condensate inside it is smaller, which can offset the elastic force of the spring 3, causing the drip tray 2 to descend. Therefore, different thresholds can be set by adjusting the position of the nut 4 to achieve different standards for raising and lowering the drip tray 2 under different conditions.

[0069] In this structure, the threshold is designed based on the elastic force of spring 3 and the weight of water tray 2. When the position of nut 4 is fixed, if there is no condensate in water tray 2, the weight of water tray 2 is less than the elastic force of spring 3 on water tray 2, and at this time, water tray 2 abuts against outdoor unit chassis 1. When the condensate in water tray 2 gradually increases, if the weight of water tray 2 and condensate is less than or equal to the elastic force of spring 3 on water tray 2, water tray 2 still abuts against outdoor unit chassis 1, and at this time, condensate can only be discharged from outlet 22.

[0070] As the condensate in the water collection chamber 23 increases, until the weight of the water collection tray 2 and the condensate exceeds the elastic force of the spring 3 on the water collection tray 2, the water collection tray 2 slides downward along the guide post 12 under the action of gravity, still separated from the outdoor unit chassis 1. At this time, the condensate can drain through the gap between the outdoor unit chassis 1 and the water collection tray 2. An increase in condensate in the water collection chamber 23 can occur in two situations: one is that the outlet 22 is blocked due to icing or other reasons, and the other is that there is an abnormality inside the air conditioner, resulting in a large amount of condensate. In either case, the condensate in the water collection chamber 23 needs to be drained promptly. When the water collection tray 2 separates from the outdoor unit chassis 1, a gap is formed between the top of the water collection tray 2 and the outdoor unit chassis 1. This gap allows the condensate to drain from the top of the water collection tray 2 when the water collection chamber 23 is full of condensate.

[0071] In a low-temperature environment, if the condensate in the water receiving chamber 23 freezes, the condensate flowing into the water receiving chamber 23 may continue to freeze on the ice surface, which will intensify the freezing phenomenon in the water receiving pan 2. At this time, as the amount of ice increases, the gravity of the water receiving pan 2 and the frozen condensate will continue to increase. Under the action of gravity, the water receiving pan 2 will further compress the spring 3, causing the water receiving pan 2 to continue to descend, which will widen the gap between the water receiving pan 2 and the outdoor unit chassis 1, ensuring that the condensate that continues to flow into the water receiving chamber 23 can be discharged through the widened gap, rather than intensifying the freezing phenomenon on the ice surface.

[0072] In this embodiment, the sliding structure of spring 3 combined with gravity is particularly suitable for use in low-temperature outdoor environments, which can avoid the problem of condensate not being able to drain due to the freezing of water tray 2.

[0073] Example 3

[0074] like Figures 1-6 As shown, the present application provides an air conditioner outdoor unit chassis, comprising:

[0075] The drainage opening is located in the outdoor unit chassis 1;

[0076] A water receiving tray 2 located below the drainage gap; the water receiving tray 2 is provided with a water outlet 22;

[0077] The water receiving tray 2 is slidably connected to the outdoor unit chassis 1 via a sliding member, and the sliding member can drive the water receiving tray 2 to rise and fall below the drainage gap;

[0078] When the condensate in the drip tray 2 is less than or equal to the threshold, the sliding member drives the drip tray 2 to slide to the position where it abuts against the outdoor unit chassis 1; when the condensate in the drip tray 2 is greater than the threshold, the sliding member drives the drip tray 2 to descend.

[0079] The sliding component of this application includes guide posts 12 located at both ends of the water receiving tray 2. The top end of the guide post 12 is fixedly connected to the outdoor unit chassis 1. The guide post 12 passes through both ends of the water receiving tray 2 and is slidably connected to the water receiving tray 2.

[0080] In this application, there are two guide pillars 12, which are fixed to the bottom of the outdoor unit chassis 1. A water receiving chamber 23 is provided in the middle of the water receiving tray 2, and protrusions extending above the water receiving chamber 23 are provided at both ends. Guide holes 21 are provided on the protrusions, with the inner diameter of the guide holes 21 slightly larger than the outer diameter of the guide pillars 12. The top of the guide pillar 12 is fixedly connected to the outdoor unit chassis 1; the bottom of the guide pillar 12 passes through the guide holes 21 and is located below the water receiving tray 2. In this application, the guide pillars 12 provide guidance for the sliding of the water receiving tray 2. Simply setting the guide pillars 12 vertically ensures that the water receiving tray 2 can smoothly rise and fall along the guide pillars 12.

[0081] Furthermore, a driving component is provided on the side of the water receiving tray 2, and the output end of the driving component is connected to the water receiving tray 2; a water level detector is provided in the water receiving tray 2.

[0082] In this embodiment, a cylinder or other driving component is installed on the side of the water receiving pan 2, and a water level sensor is installed in the water receiving chamber 23. The height of the water level sensor is observed to determine whether the condensate in the water receiving chamber 23 has reached a threshold. If the threshold is reached, the driving component operates, causing the water receiving pan 2 to descend. The driving component and the water level sensor can be connected in communication, or both can be connected to the controller of a corresponding appliance such as an air conditioner, enabling interaction between the water level sensor and the driving component.

[0083] In this embodiment, the drive unit and the sliding component of the water level detector are suitable for use in a normal temperature environment. If ice forms in the water receiving chamber 23, the water level detector will not be able to detect the water level of the condensate normally.

[0084] Example 4

[0085] like Figures 1-6 As shown, the present application provides an air conditioner outdoor unit chassis, comprising:

[0086] The drainage opening is located in the outdoor unit chassis 1;

[0087] A water receiving tray 2 located below the drainage gap; the water receiving tray 2 is provided with a water outlet 22;

[0088] The water receiving tray 2 is slidably connected to the outdoor unit chassis 1 via a sliding member, and the sliding member can drive the water receiving tray 2 to rise and fall below the drainage gap;

[0089] When the condensate in the drip tray 2 is less than or equal to the threshold, the sliding member drives the drip tray 2 to slide to the position where it abuts against the outdoor unit chassis 1; when the condensate in the drip tray 2 is greater than the threshold, the sliding member drives the drip tray 2 to descend.

[0090] In this embodiment, the outdoor unit chassis 1 is suitable for low-temperature environments. Therefore, heating pipes 6 need to be installed in the outdoor unit chassis 1 for electric heating to prevent the outdoor unit chassis 1 from freezing.

[0091] Specifically, this application also includes an adjusting resistor 5 and a heating line 6 disposed in the outdoor unit chassis 1. The adjusting resistor 5 and the heating line 6 are connected in series to both ends of the power supply to form a heating path; the heating line 6 is distributed in the heating chassis.

[0092] The adjustable resistor 5 refers to a resistor with variable resistance. The heating pipes 6 are evenly distributed on the upper surface of the outdoor unit chassis 1. The heating pipes 6 are similar to heating resistors. When powered on, the heating pipes 6 will heat up and heat various parts of the outdoor unit chassis 1 to ensure that the temperature of the outdoor unit chassis 1 is higher than the freezing temperature, thus preventing condensate and other substances from freezing in the outdoor unit chassis 1.

[0093] In this application, the heating pipe 6 is connected in series with the regulating resistor 5 and connected to an external power supply. The regulating resistor 5 is fixed on the upper surface of the outdoor unit chassis 1. The heating pipe 6 extends into the electrical box 8 after being connected in series with the regulating resistor 5, and is connected to the external power supply inside the electrical box 8.

[0094] In this application, the regulating resistor 5 is connected in series with the heating pipe 6, and the resistance value of the regulating resistor 5 can be varied. When it is necessary to enhance the heating effect of the heating pipe, the resistance value of the regulating resistor 5 can be decreased. The resistance in the series circuit of the regulating resistor 5 and the heating pipe 6 decreases, the current increases, and the heating power of the heating pipe increases, meaning the heat generated by the heating pipe 6 will increase. When it is necessary to weaken the heating effect of the heating pipe, the resistance value of the regulating resistor 5 can be increased. The resistance in the series circuit of the regulating resistor 5 and the heating pipe 6 increases, the current decreases, and the heating power of the heating pipe decreases, meaning the heat generated by the heating pipe 6 will decrease.

[0095] Furthermore, the adjustable resistor 5 of this application includes a guide rod and an adjusting element, wherein the guide rod is a conductor; the first end of the heating pipe is fixedly connected to the guide rod, and the second end of the heating pipe can slide along the guide rod under the action of the adjusting element; when the condensate in the water receiving pan 2 is less than or equal to a threshold, the adjusting element drives the second end of the heating pipe to slide in the guide rod to a first position; when the condensate in the water receiving pan 2 is greater than the threshold, the adjusting element drives the second end of the heating pipe to slide in the guide rod to a second position; and the heating power of the heating path corresponding to the first position is less than the heating power of the heating path corresponding to the second position.

[0096] The first and second ends of the heating pipe refer to the two ends connected to the regulating resistor 5, respectively. In fact, in addition to being connected to the regulating resistor 5, the heating pipe 6 also needs to be connected to the external power supply in the electrical box 8. The heating pipe 6 between the electrical box 8 and the regulating resistor 5 is distributed at various locations on the outdoor unit chassis 1 that need to be heated.

[0097] This application uses an adjusting component to move the position of the second end of the heating pipe 6, thereby determining the portion of the guide rod connected in series into the heating path. The position of the first end of the heating pipe 6 within the guide rod is fixed. The greater the distance between the second end of the heating pipe and the first end of the heating wire, the greater the resistance of the adjusting resistor 5 connected in series into the heating path. When the condensate in the water collection pan 2 is less than or equal to the threshold, it indicates that the water collection chamber 23 can drain normally, there is no ice formation in the water collection chamber 23, and the heating pipe 6 can be heated at a lower power.

[0098] When the condensate in the drip tray 2 exceeds the threshold, it indicates that the drip chamber 23 may freeze, causing the outlet 22 to become blocked. At this time, the adjusting component moves the second end of the heating pipe, making the resistance of the adjusting resistor 5 connected in series into the heating path smaller, thereby allowing the heating pipe 6 to heat with a larger power and preventing the condensate in the outdoor unit chassis 1 from freezing.

[0099] Furthermore, the adjusting component includes a slide rod 7, both the guide rod and the slide rod 7 are vertically arranged, the second end of the heating pipe abuts against the upper end of the guide rod, and the second end of the heating pipe is fixed to one end of the slide rod 7 by a fixed bracket; the other end of the slide rod 7 is fixedly connected to the water receiving tray 2; the raising and lowering of the water receiving tray 2 can drive the slide rod 7 to rise and fall synchronously.

[0100] This application uses a slider 7 to link the resistance value of the regulating resistor 5 in the heating circuit with the position of the water tray 2. If the water tray 2 is likely to freeze, that is, if the water tray 2 is separated from the outdoor unit chassis, the resistance value of the regulating resistor 5 in the heating circuit will decrease. If the water tray 2 is not likely to freeze, that is, if the water tray 2 is in contact with the outdoor unit chassis, the resistance value of the regulating resistor 5 in the heating circuit will increase.

[0101] When the condensate in the water collection tray 2 is less than or equal to the threshold, the sliding member drives the water collection tray 2 to slide to the position where it abuts against the outdoor unit chassis 1, and the sliding rod 7 drives the second end of the heating pipe 6 to move to the upper end of the guide rod; when the condensate in the water collection tray 2 is greater than the threshold, the sliding member drives the water collection tray 2 to descend, and the sliding rod 7 drives the second end of the heating pipe to move to the lower end of the guide rod.

[0102] This embodiment can determine whether the water receiving pan 2 is frozen based on its position. The position of the water receiving pan 2 is linked to the resistance value of the adjusting resistor 5 in the heating path through the slide rod 7, so as to realize intelligent automatic adjustment of the power of the heating pipeline 6 and avoid energy waste of the heating pipeline.

[0103] Example 5

[0104] like Figures 1-6 As shown, this application provides an air conditioner outdoor unit chassis suitable for low-temperature environments, such as ambient temperatures of 0°C and below. Specifically, it includes:

[0105] The drainage opening is located in the outdoor unit chassis 1;

[0106] A water receiving tray 2 located below the drainage gap; the water receiving tray 2 is provided with a water outlet 22;

[0107] The water collection tray 2 is slidably connected to the outdoor unit chassis 1 via a sliding member. The sliding member can drive the water collection tray 2 to rise and fall below the drainage gap. When the condensate in the water collection tray 2 is less than or equal to a threshold, the sliding member drives the water collection tray 2 to slide to a position where it abuts against the outdoor unit chassis 1. When the condensate in the water collection tray 2 is greater than the threshold, the sliding member drives the water collection tray 2 to fall.

[0108] The sliding component includes guide posts 12 located at both ends of the water receiving tray 2, and springs 3 nested on the guide posts 12. The top end of the guide post 12 is fixedly connected to the outdoor unit chassis 1; the guide post 12 passes through both ends of the water receiving tray 2 and is slidably connected to the water receiving tray 2; the top end of the spring 3 abuts against the water receiving tray 2, and the bottom end of the spring 3 abuts against the bottom of the guide post 12. A nut 4 is provided at the bottom end of the guide post 12, and the nut 4 is connected to the bottom of the guide post 12 by a thread 121. A washer is provided between the nut 4 and the spring 3.

[0109] To prevent the outdoor unit chassis from freezing at low temperatures, this application also includes an adjustable resistor 5 and a heating pipe 6 disposed in the outdoor unit chassis 1. The adjustable resistor 5 and the heating pipe 6 are connected in series to both ends of the power supply to form a heating path; the heating pipe 6 is distributed in the heating chassis. The heating pipe 6 is connected in series with the adjustable resistor 5 and connected to an external power supply. The adjustable resistor 5 is fixed to the upper surface of the outdoor unit chassis 1, and the heating pipe 6 extends into the electrical box 8 after being connected in series with the adjustable resistor 5, and is connected to the external power supply inside the electrical box 8.

[0110] The adjusting resistor 5 includes a guide rod and an adjusting component. The guide rod is a conductor. The adjusting component includes a sliding rod 7. Both the guide rod and the sliding rod 7 are vertically arranged. The first end of the heating pipe is fixedly connected to the guide rod, and the second end of the heating pipe abuts against the upper end of the guide rod. The second end of the heating pipe is fixed to one end of the sliding rod 7 through a fixed bracket. The second end of the heating pipe can slide along the guide rod under the action of the sliding rod 7. The other end of the sliding rod 7 is fixedly connected to the limiting groove 24 in the water receiving tray 2. The raising and lowering of the water receiving tray 2 can drive the sliding rod 7 to rise and fall synchronously.

[0111] When the condensate in the water collection tray 2 is less than or equal to the threshold, the slide rod 7 drives the second end of the heating pipeline to slide to the first position in the guide rod; when the condensate in the water collection tray 2 is greater than the threshold, the slide rod 7 drives the second end of the heating pipeline to slide to the second position in the guide rod; and the heating power of the heating path corresponding to the first position is less than the heating power of the heating path corresponding to the second position.

[0112] Specifically, a groove 51 can be provided on the side of the adjusting resistor 5 facing the slide rod 7, and the fixed bracket can slide in the groove 51 to guide and restrict the sliding trajectory of the fixed bracket.

[0113] If the drip tray 2 is not frozen, the weight of the drip tray 2 and the condensate is less than or equal to the elastic force of the spring 3 on the drip tray 2. The drip tray 2 remains in contact with the outdoor unit chassis 1. The air conditioner operates in heating mode, and the condensate produced by the condenser collects on the outdoor unit chassis 1 and flows into the drip tray 2, quickly flowing through the outlet 22 into the natural environment outside the casing. At this time, if... Figure 4 and Figure 5 As shown, the water receiving tray 2 is at its highest position, the distance between the second end and the first end of the heating pipe is the largest, the resistance value of the adjusting resistor 5 in the heating circuit is the largest, and it is much greater than the resistance value of the heating pipe. At this time, the current in the heating circuit is almost zero, that is, the heating circuit is in an open circuit state, and the heating pipe 6 does not heat.

[0114] When the air conditioner operates continuously in heating mode, if the outlet 22 of the drip tray 2 becomes blocked due to ice or other reasons, the condensate in the drip chamber 23 will continuously increase until the weight of the drip tray 2 and the condensate exceeds the elastic force of the spring 3 on the drip tray 2. Under the action of gravity, the drip tray 2 slides downward along the guide post 12, still separated from the outdoor unit chassis 1. At this time, the condensate can drain through the gap between the outdoor unit chassis 1 and the drip tray 2. This avoids problems such as waterlogging or ice buildup caused by poor drainage inside the chassis. At this point, the slide rod 7 descends to the middle position along with the drip tray 2, as... Figure 3 As shown, the distance between the second end and the first end of the heating pipe is moderate. Adjusting the resistance value of resistor 5 in the heating path decreases, and the current in the heating path increases. The power range of the heating pipe is 20W-50W, which avoids ice formation on the upper surface of the outdoor unit chassis.

[0115] When the air conditioner operates continuously in heating mode, under extreme weather conditions, the condensate in the drip tray 2 begins to freeze. The condensate continuously flows down, pouring onto the ice surface of the drip tray 2. The ice layer gradually accumulates and thickens, exceeding the upper edge of the drip tray 2, continuously increasing its weight and further compressing the spring 3. At this point, the drip tray 2 continues to descend to its lowest position, widening the gap between the drip tray 2 and the outdoor unit chassis 1. This ensures that the condensate continuing to flow into the drip chamber 23 can drain through this widened gap, rather than exacerbating the freezing phenomenon on the ice surface. In this situation, the slide bar 7 descends to the middle position along with the drip tray 2, minimizing the distance between the second and first ends of the heating pipe, minimizing the resistance value of the regulating resistor 5 integrated into the heating path, maximizing the current in the heating path, and setting the power range of the heating pipe to 80W-120W, thus preventing ice formation on the upper surface of the outdoor unit chassis.

[0116] Example 6

[0117] The difference from Embodiment 5 is that the sliding component includes a spring and a hinge assembly. One end of the water tray 2 is hinged to the outdoor unit chassis via the hinge assembly, and the other end is fixed to the bottom of the outdoor unit chassis via the spring. When the water tray 2 descends, one end remains stationary, while the other end descends under the action of gravity, overcoming the tension of the spring 3, thus achieving the purpose of raising and lowering the water tray 2.

[0118] The remaining structure and usage are as shown in Example 5, and will not be described in detail again.

[0119] This application also provides an air conditioner, including the air conditioner outdoor unit chassis as described above.
