[0033] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[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 external unit casing 1, a condenser and a hole blocking component 2 (or it can be called a movable shell); the external unit casing 1 has an accommodating space and a first heat exchange hole 11 that can be connected to the accommodating space; the condenser is arranged in the accommodating space; the hole blocking component 2 is arranged in the external unit casing 1, and is used to block the first heat exchange hole 11 when the outdoor unit stops running.

[0039] The outdoor unit and air conditioner provided by the present invention, the outdoor unit includes a hole blocking component 2 arranged on the external unit casing 1, when the outdoor unit stops running, the hole blocking component 2 can block the first heat exchange hole 11, thereby, when the outdoor unit stops running, dirt (such as dust) in the external environment cannot pass through the heat exchange hole to enter the external unit casing 1, and the dirt in the external environment will not contact the condenser, thereby not causing the dirt to adhere to the condenser. Therefore, it can solve the technical problem in the prior art that when the outdoor unit stops running, dirt (such as dust) in the external environment can pass through the heat exchange hole to enter the external unit casing 1 and contact the condenser, causing the dirt to adhere to the condenser, thereby 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 accommodating space of the external housing 1 through the first heat exchange hole 11 and exchange heat with the condenser in the accommodating space; for example, the external housing 1 can have two first heat exchange holes 11, one is an air inlet and the other is an air outlet.

[0041] like Figure 2 As shown, according to one embodiment of the present invention, the hole blocking component 2 may include a first driving part 21 and a sealing part 22; the first driving part 21 is arranged in the external housing 1 and connected to the sealing part 22 for driving the sealing part 22; the sealing part 22 is arranged in the external housing 1.

[0042] During specific implementation, the first driving part 21 can drive the blocking part 22 to block the first heat exchange hole 11 through the blocking part 22 .

[0043] like Figure 2 As shown, in some embodiments, the hole blocking component 2 may further include a hole blocking component shell 23, which is located above the first heat exchange hole 11 and connected to the side wall of the external housing 1, and the first driving part 21 is disposed in the hole blocking component shell 23, and the blocking part 22 can be accommodated in the hole blocking component shell 23, that is, the blocking part 22 can extend from the hole blocking component shell 23, thereby blocking the first heat exchange hole 11.

[0044] like Figure 2 As shown, according to one embodiment of the present invention, the first heat exchange hole 11 is arranged on the side wall of the outer casing 1; the first driving part 21 includes a first motor 211 and a reel 212; the first motor 211 is arranged 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 in the transverse direction, is located above the first heat exchange hole 11 and is rotatably connected to the side wall of the outer casing 1; the blocking part 22 can be rolled up on the reel 212, and is used to unfold downward to block the first heat exchange hole 11 under the rotation of the reel 212; or, the blocking part 22 is used to be retracted upward to expose the first heat exchange hole 11 under the rotation of the reel 212.

[0045] In a specific implementation, the blocking portion 22 is equivalent to a rolling curtain, which can be unfolded downward to block the first heat exchange hole 11; the rolling curtain can be retracted upward to expose the first heat exchange hole 11. That is, when the outdoor unit stops running, the blocking portion 22 is unfolded downward to block the first heat exchange hole 11 under the rotation of the reel 212 (for example, clockwise); when the outdoor unit is in a cooling mode or a heating mode, the blocking portion 22 is retracted upward to expose the first heat exchange hole 11 under the rotation of the reel 212 (for example, counterclockwise).

[0046] like Figure 2 As shown, Figure 2 The illustrated state is an expanded state. In this embodiment, the blocking portion 22 is expanded and retracted vertically. In some embodiments, the blocking portion 22 can be expanded and retracted horizontally.

[0047] like Figure 1 As shown, according to one embodiment of the present invention, the outer housing 1 also has a second heat exchange hole 12 that can be connected to the accommodating space; the outdoor unit also includes an area adjustment component 3, which is arranged on the outer housing 1 and is used to adjust the first exposed area of ​​the second heat exchange hole 12 to the second exposed area when the first heat exchange hole 11 is blocked; wherein the first exposed area is larger 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 running. For example, in winter, rainwater or snow water penetrates into the outer casing 1 and freezes to freeze the output end of the motor used to drive the fan blades to rotate. Therefore, the outdoor unit usually controls the motor to run at intervals through program control, and uses the heat released by the condenser to remove ice / water. If the area adjustment component 3 is not provided, the exposed area of ​​the second heat exchange hole 12 is too large. For example, the first heat exchange area is exposed, and rainwater or snow water is easy to penetrate into the outer casing 1; if the second heat exchange hole 12 is completely blocked, the air in the outer casing 1 cannot circulate, affecting the de-icing / water effect. Therefore, through the above-mentioned structural setting, there is no need for the first drive part 21 to frequently drive the blocking part 22 to expose the first heat exchange hole 11, and the second heat exchange hole 12 can be exposed by exposing the second exposed area.

[0049] According to one embodiment of the present invention, when the outdoor unit is in a stopped state, the area adjusting 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 part 31 can drive the adjusting part 32 , and the adjusting part 32 can adjust the first exposed area of ​​the second heat exchange hole 12 to the second exposed area.

[0052] Understandably, Figure 8 The second heat exchange hole 12 is in the state of the first exposed area. Fig. 9 This is the state where the second heat exchange hole 12 has the second exposed area.

[0065] In some embodiments, the outdoor unit of the present invention may further include a reserve capacitor. The external 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 is abnormally powered off 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, the first heat exchange hole 11 can be blocked, and the first exposed area of ​​the second heat exchange hole 12 can be adjusted 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 garbage of a predetermined size (larger garbage) from entering the outer housing 1 .

[0067] In some embodiments, when the air conditioner is operated in the heating mode in winter, due to the low temperature of the external environment and the air conditioner's own settings, in order to ensure the heat exchange efficiency of the condenser, the air conditioner usually enters the defrost mode after running for a period of time, and the indoor unit stops running and is in standby state. The indoor unit has no heat output. After entering the defrost stage, the four hole blocking components 2 arranged on the four side walls of the external unit housing 1 are actuated after receiving the command, and are expanded downward to block the first heat exchange hole 11, so that the outdoor unit relies on the compressor to release heat from the condenser when working, thereby utilizing the internal heat cycle for rapid defrosting. 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 time of the defrost stage and improve the defrost efficiency.

[0068] In some embodiments, for northern icy areas in winter, when the air conditioner is operated in heating mode in winter, the refrigerant in the condenser needs to evaporate and absorb heat. Since the external ambient temperature is low, the refrigerant is not easy to absorb heat, and the actual heat cycle of the condenser is poor. At this time, the hole blocking component 2 blocks the first heat exchange hole 11 to reduce heat loss.

[0069] The present invention also provides an air conditioner, comprising 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 of the above embodiment, and will not be described in detail here.
