As shown in fig. 14 and 16, the stop valve protection cover comprises a sliding rod 9 and the protection member 2 comprises a blocking portion, as shown in fig. 15 and 17, the stop valve protection cover comprises a sliding rod 9 and the protection member 2 comprises two blocking portions. Each sliding rod 9 is provided with a blocking part correspondingly connected, one end of each blocking part is connected with the corresponding sliding rod 9, and the other end of each blocking part is fixedly connected with the stop valve protective cover. Each slide bar 9 has a corresponding through hole in which the slide bar 9 slides to control the blocking portion to block the accommodation space. The sliding rod 9 drives the blocking part to slide or deform for controlling the blocking part to block the accommodating space. In rainy and snowy weather, because the wind direction and the wind force are different in magnitude, the protection part 2 is rotated to form a certain angle with a side plate of the outdoor unit of the air conditioner, so that foreign matters such as rain and snow can be effectively prevented from passing through, the air inlet quantity of an online connecting line connecting opening of the outdoor unit is ensured, heat dissipation is facilitated, and in some optional embodiments, in an application scene that mosquitoes and other small animals rarely appear and no rain or snow falls, the sliding rod 9 can adjust the blocking area of the protection part to the containing space to the minimum.
The utility model provides a protector is add to stop valve protection casing, and through setting up the protector and blocking accommodation space between stop valve protection casing opening and off-premises station online line connection opening, in order to avoid arousing the circuit short circuit if getting into the electric cabinet via stop valve protection casing opening and off-premises station online line connection opening, the hidden danger of the damage of the outer machine of air conditioner or even conflagration has been eliminated because of the circuit short circuit causes, and the combination of slide bar and protector makes the protector adjustable to the blocking area of accommodation space, guarantee off-premises station online line connection opening thermal diffusivity.
In the foregoing embodiments, the material of the protection component 2 is selected in various forms, in some alternative embodiments, the protection component 2 is a hard plate-shaped structure, and in some alternative embodiments, the protection component 2 is a flexible protection component that is easy to deform, for example: window screening. Preferably, in the embodiment of the present invention, the protection member 2 is a flexible protection member. The flexible protection piece is adopted, so that the phenomenon that insects, other small animals, rain, snow and other foreign matters enter the outdoor unit online line connecting opening through the opening 1 to cause short circuit of a circuit, the short circuit can cause damage of an outdoor unit of an air conditioner and even cause fire can be effectively prevented, the protection piece 2 is prevented from influencing heat dissipation of the outdoor unit online line connecting opening, and the manufacturing cost of the protection piece 2 is reduced.
The through holes determine the sliding track of the sliding rod 9, in some alternative embodiments, when the protection member 2 is of a hard plate-shaped structure, the protection member 2 is not easy to deform, and the through holes are arc-shaped through holes, as shown in fig. 15, so that the sliding rod 9 drives the protection member 2 to move in an arc-shaped track as shown in fig. 18. In some optional embodiments, when the protection component 2 is an easily deformable flexible protection component, the through hole is an arc-shaped through hole or a strip-shaped through hole, and preferably, when the protection component 2 is an easily deformable flexible protection component, the through hole is a strip-shaped through hole, which reduces the difficulty of the manufacturing process and improves the production efficiency. When the through-hole is a bar-shaped through-hole, the movement of the slide bar 9 is not affected due to the easy deformation property of the protection member 2. In some alternative embodiments, when the protection member 2 is a flexible protection member easy to deform, the sliding rod 9 rotates around the axial direction of the sliding rod 9 during the sliding process of the through hole, so as to wind the protection member 9 on the sliding rod 9 for storing the protection member 2.
In some optional embodiments, when the protection member 2 is a hard plate structure, the blocking portion is provided with a plurality of air holes for facilitating heat dissipation of the connection line connection opening of the outdoor unit. In order to effectively prevent insects, other small animals, rain, snow and other foreign matters from damaging the air conditioner through the outdoor unit online connecting line connecting opening, the aperture of the air holes is not too large easily. Optionally, in order to reduce the manufacturing difficulty of the protection part 2 and accelerate the production rate, the air holes are round holes, and the diameter of each round hole is 0.5 mm-2 mm. Optionally, the diameter of the circular hole is 0.5mm, 1mm, 1.5mm or 2 mm.
In some optional embodiments, when the stop valve protection cover includes two or more sliding rods 9, the sliding rods 9 are disposed in a direction perpendicular to the side plate of the outdoor unit, and the sliding rods 9 slide in a direction perpendicular to the side plate of the outdoor unit.
In some optional embodiments, when the protective cover of the stop valve comprises a sliding rod 9, the sliding rod 9 is disposed in a direction parallel or perpendicular to the side plate of the outdoor unit, and the sliding rod 9 slides in a direction parallel or perpendicular to the side plate of the outdoor unit.
The embodiment of the disclosure also provides an outdoor unit, which comprises the stop valve protective cover in any one of the embodiments.
An embodiment of the present disclosure further provides an air conditioner, including the outdoor unit, where the outdoor unit includes the stop valve protection cover in any of the foregoing embodiments.
It is to be understood that the present invention is not limited to the procedures and structures described above and shown in the drawings, and that various modifications and changes may be made without departing from the scope thereof. The scope of the invention is limited only by the appended claims.
