Description

Technical Field

[0001] This invention relates to the field of mechanical equipment technology, and more particularly to an outdoor unit and an air conditioner. Background Technology

[0002] An air conditioner, also known as an air conditioner, is a device that uses artificial means to regulate and control parameters such as temperature, humidity, and airflow rate of the air inside a building or structure.

[0003] Taking a multi-split central air conditioning system as an example, in order to enable the condenser of the outdoor unit to exchange heat with the air in the external environment, multiple heat exchange holes (air inlet and air outlet) are opened on the surface of the outdoor unit casing. This allows the condenser inside the outdoor unit casing to come into contact with the air in the external environment, thereby achieving heat exchange. The more heat exchange holes are set, the larger the contact area between the condenser and the air, and thus the higher the heat exchange efficiency.

[0004] However, due to the changing weather throughout the year, the outdoor unit is not working for a certain period of time. That is, people do not use air conditioning every day of the year, and the outdoor unit is not running for a certain period of time. As a result, dirt (such as dust) in the external environment can enter the outdoor unit casing through the heat exchange holes and come into contact with the condenser.

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this embodiment, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In this embodiment, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

[0038] Figures 1 to 9 The outdoor unit and air conditioner provided by the present invention are shown. As can be seen from the figure, the outdoor unit of the present invention includes an outdoor unit housing 1, a condenser and a plugging component 2 (or movable outer shell); the outdoor unit housing 1 has an accommodating space and a first heat exchange hole 11 that can communicate with the accommodating space; the condenser is disposed in the accommodating space; the plugging component 2 is disposed in the outdoor unit housing 1 and is used to plug the first heat exchange hole 11 when the outdoor unit is not running.

[0039] The outdoor unit and air conditioner provided by the present invention include a plugging component 2 disposed on the outdoor unit housing 1. When the outdoor unit is not running, the plugging component 2 can block the first heat exchange hole 11. Thus, when the outdoor unit is not running, dirt (such as dust) in the external environment cannot enter the outdoor unit housing 1 through the heat exchange hole, and the dirt in the external environment will not come into contact with the condenser, thereby preventing dirt from adhering to the condenser. Therefore, it can solve the technical problem in the prior art that when the outdoor unit is not running, dirt (such as dust) in the external environment can enter the outdoor unit housing 1 through the heat exchange hole and come into contact with the condenser, resulting in dirt adhering to the condenser and affecting the heat exchange efficiency and service life of the condenser.

[0040] In this embodiment, the first heat exchange hole 11 can be an air inlet and / or an air outlet. That is, the air from the external environment can enter the housing space of the outdoor unit housing 1 through the first heat exchange hole 11 and exchange heat with the condenser of the housing space. For example, the outdoor unit housing 1 can have two first heat exchange holes 11, one for air inlet and the other for air outlet.

[0041] like Figure 2 As shown, according to one embodiment of the present invention, the plugging component 2 may include a first driving part 21 and a plugging part 22; the first driving part 21 is disposed on the outer casing 1 and connected to the plugging part 22, and is used to drive the plugging part 22; the plugging part 22 is disposed on the outer casing 1.

[0042] In specific implementation, the first driving unit 21 can drive the sealing unit 22 to block the first heat exchange hole 11 through the sealing unit 22.

[0043] like Figure 2 As shown, in some embodiments, the plugging component 2 may further include a plugging component housing 23, located above the first heat exchange hole 11 and connected to the side wall of the outdoor unit housing 1. The first driving part 21 is disposed inside the plugging component housing 23, and the sealing part 22 can be accommodated in the plugging component housing 23. That is, the sealing part 22 can extend out from the plugging component housing 23 to block the first heat exchange hole 11.

[0044] like Figure 2 As shown, according to one embodiment of the present invention, a first heat exchange hole 11 is provided on the side wall of the outdoor unit housing 1; a first drive unit 21 includes a first motor 211 and a reel 212; the first motor 211 is provided above the first heat exchange hole 11, and the output end of the first motor 211 is connected to the end of the reel 212; the reel 212 is arranged laterally, located above the first heat exchange hole 11 and rotatably connected to the side wall of the outdoor unit housing 1; a sealing part 22 can be wound onto the reel 212 and is used to unfold downward under the rotation of the reel 212 to block the first heat exchange hole 11; or, the sealing part 22 is used to retract upward under the rotation of the reel 212 to expose the first heat exchange hole 11.

[0045] In practice, the sealing part 22 is equivalent to a roller shutter. When the roller shutter is rolled down, it blocks the first heat exchange hole 11; when the roller shutter is rolled up, it exposes the first heat exchange hole 11. That is, when the outdoor unit is not running, the sealing part 22 is rolled down to block the first heat exchange hole 11 by rotating the roller 212 (e.g., clockwise); when the outdoor unit is in cooling mode or heating mode, the sealing part 22 is rolled up to expose the first heat exchange hole 11 by rotating the roller 212 (e.g., counterclockwise).

[0046] like Figure 2 As shown, Figure 2 The diagram shows the unfolded state. In this embodiment, the sealing part 22 unfolds and retracts vertically; in some embodiments, the sealing part 22 can unfold and retract horizontally.

[0047] like Figure 1 As shown, according to one embodiment of the present invention, the outdoor unit housing 1 further has a second heat exchange hole 12 that can communicate with the accommodating space; the outdoor unit also includes an area adjustment component 3, which is disposed on the outdoor unit housing 1 and is used to adjust the first exposed area of ​​the second heat exchange hole 12 to a second exposed area when the first heat exchange hole 11 is blocked; wherein, the first exposed area is greater than the second exposed area.

[0048] In specific implementation, the state in which the first heat exchange hole 11 is blocked corresponds to the state in which the outdoor unit stops operating. For example, in winter, rainwater or snow water seeps into the outdoor unit casing 1 and freezes, which will freeze the output end of the motor used to drive the fan blades. Therefore, the outdoor unit will usually control the motor to run intermittently through program control, using the heat released by the condenser to defrost / water. If the area adjustment component 3 is not set, the exposed area of ​​the second heat exchange hole 12 will be too large, for example, the first heat exchange area will be exposed, and rainwater or snow water will easily seep into the outdoor unit casing 1. If the second heat exchange hole 12 is completely blocked, the air in the outdoor unit casing 1 will not be able to circulate, affecting the defrosting / water effect. Therefore, with the above structural setting, it is not necessary for the first drive unit 21 to frequently drive the sealing part 22 to expose the first heat exchange hole 11. The second heat exchange hole 12 can be exposed by the second exposed area.

[0049] According to one embodiment of the present invention, when the outdoor unit is in a stopped state, the area adjustment component 3 can adjust the second exposed area of ​​the second heat exchange hole 12 to the first exposed area, and the hole blocking component 2 can block the first heat exchange hole 11.

[0051] In a specific implementation, the second driving unit 31 can drive the adjustment unit 32, and the adjustment unit 32 can adjust the first exposed area of ​​the second heat exchange hole 12 to the second exposed area.

[0052] Understandable Figure 8 The second heat exchange hole 12 is in the state where the first exposed area is. Figure 9 The second heat exchange hole 12 represents the state of the second exposed area.

[0055] In some embodiments, the area adjustment component 3 may include two adjustment parts 32, which are arranged opposite each other along an axial direction perpendicular to the gear 312, so that the two adjustment parts 32 can be driven by one gear 312.

[0065] In some embodiments, the outdoor unit of the present invention may further include a reserve capacitor. The outdoor unit housing 1 is provided with a computer board, which is connected to the reserve capacitor, the first motor 211, and the second motor 311. When the outdoor unit loses power abnormally due to its own reasons or external reasons, the reserve capacitor can ensure that the sealing part 22 and the adjustment part 32 can be used normally, that is, it can block the first heat exchange hole 11 and adjust the first exposed area of ​​the second heat exchange hole 12 to the second exposed area.

[0066] In some embodiments, the outdoor unit of the present invention may further include a grid covering the first heat exchange hole 11 and the second heat exchange hole 12 to prevent debris of a predetermined size (larger debris) from entering the outdoor unit housing 1.

[0067] In some implementations, when the air conditioner is running in heating mode during winter, due to the low external temperature and the air conditioner's own settings, in order to ensure the heat exchange efficiency of the condenser, the air conditioner will usually enter defrost mode after running for a period of time. The indoor unit will stop running and be in standby mode, with no heat output from the indoor unit. After entering the defrost stage, the four plugging hole components 2 located on the four side walls of the outdoor unit casing 1 will act after receiving the command and unfold downwards to block the first heat exchange hole 11. This allows the outdoor unit to release heat from the condenser when the compressor is working, thereby utilizing the internal heat circulation to quickly defrost. Since the first heat exchange hole 11 is blocked, the heat released by the condenser is not easily lost to the outside, which can shorten the defrost stage time and improve defrost efficiency.

[0068] In some implementations, for cold northern regions in winter, when the air conditioner is running in heating mode, the refrigerant in the condenser needs to evaporate and absorb heat. Due to the low ambient temperature, the refrigerant does not easily absorb heat, and the actual heat cycle of the condenser is poor. At this time, the plugging component 2 blocks the first heat exchange hole 11 to reduce heat loss.

[0069] The present invention also provides an air conditioner, including an outdoor unit and an indoor unit, wherein the indoor unit is connected to the outdoor unit. The specific structure, working principle, and beneficial effects of the outdoor unit are the same as those in the above embodiments, and will not be repeated here.
