Detailed Embodiment

[0032] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0033] Please refer to Figures 1-6 , a sinking installation structure for a multi-connected air conditioner outdoor unit, which includes a sinking mechanism 1 and an air conditioner outdoor unit lifting mechanism 2. The air conditioner outdoor unit lifting mechanism 2 is installed inside the sinking mechanism 1, and the air conditioner outdoor unit lifting mechanism 2 drives the air conditioner outdoor unit to lift;

[0034] The sinking mechanism 1 includes a concrete support 101, which is embedded below the ground. Pipes for entering the room are embedded on the side of the concrete support 101, so that the power supply of the multi-connected air conditioner can be connected to the indoor unit indoors;

[0035] A lifting opening 102 is provided at the top of the concrete support 101, and two air return mechanisms 103 are provided on both sides of the concrete support 101. The air return mechanisms 103 are provided with air outlets;

[0036] The air outlets of the air return mechanisms 103 are above the ground.

[0037] Through the above technical solution, the concrete support 101 is arranged underground, and the multi-connected air conditioner outdoor unit can enter through the lifting opening 102. At the same time, the air return mechanisms 103 are arranged on the top of the concrete support 101. When the multi-connected air conditioner outdoor unit works, a large amount of heat will be generated, making the inside of the concrete support 101 in a high temperature and high pressure state. According to the characteristics of air flow, hot air will flow towards the cold air direction. Therefore, the hot air flows out a large amount through the air return mechanism 103 on one side, and the cold air is inhaled through the air return mechanism 103 on the other side, achieving the effect of improving air exchange.

[0038] Specifically, the number of the air return mechanisms 103 is more than two, and multiple air return mechanisms 103 are respectively arranged on both sides of the lifting opening 102.

[0039] Through the above technical solution, the number of the air return mechanisms 103 is at least two, which is used to enable air to be exchanged. When the number of multi-connected air conditioner outdoor units increases, the number of the air return mechanisms 103 needs to be increased correspondingly, so as to avoid the on-off congestion of the air flow and the poor air exchange effect.

[0040] Specifically, the air return mechanism 103 is in an inverted U shape, and one end of the bottom of the air return mechanism 103 communicates with the inside of the concrete support 101, and the height of the other end of the bottom of the air return mechanism 103 is half of the total height of the air return mechanism 103;

[0041] A ventilation fan 1031 is installed inside the air return mechanism 103.

[0042] Through the above technical solution, the air return mechanism 103 is set in an inverted U shape, so as to prevent the opening of the air return mechanism 103 from facing directly upwards. When the opening of the air return mechanism 103 faces upwards, during rainy weather, rainwater will pour into the inside of the inverted concrete support 101 through the air return mechanism 103, causing the multi-connected air conditioner outdoor unit to be soaked in water;

[0043] And when the equipment is in a sunken state, active ventilation and heat dissipation are carried out through the operation of the ventilation fan 1031 to improve the heat dissipation efficiency.

[0044] Specifically, a support boss 104 is fixedly connected to the inner bottom of the concrete support 101. The support boss 104 protrudes from the inner bottom of the concrete support 101, and the support boss 104 supports the air conditioner outdoor unit lifting mechanism 2.

[0045] Through the above technical solution, the purpose of setting the support boss 104 at the inner bottom of the concrete support 101 is to raise the installation surface of the lifting drive rod 201 to protect the lifting drive rod 201 and the multi-connected air conditioner outdoor unit installed on the outdoor unit support platform 203. For the mechanisms located underground, it is inevitable that moisture will return during rainy and humid weather. When moisture returns, there may be a small amount of accumulated water inside the concrete support 101. Therefore, for safety, protective measures are set in advance for protection;

[0046] The small amount of accumulated water does not need to be specially treated. When the multi-connected air conditioner outdoor unit is working, the heat generated by it and the flowing air will gradually keep the internal space of the concrete support 101 dry.

[0047] Specifically, the air conditioner outdoor unit lifting mechanism 2 includes a lifting drive rod 201. The lifting drive rod 201 is a device with a linear telescopic function such as a hydraulic rod or an electric push rod, and the number of the lifting drive rods 201 is four;

[0048] All four lifting drive rods 201 are composed of a fixed rod at the bottom and a movable rod at the upper part sleeved together. A connecting piece 202 is fixedly connected to the outer surface of the upper movable rod. The connecting piece 202 is in an inverted L shape, and the end of the connecting piece 202 away from the movable rod extends downward to the bottom of the lifting drive rod 201;

[0049] A foreign machine support platform 203 is fixedly connected between the bottoms of the four connectors 202, and the foreign machine support platform 203 supports the foreign machine of the multi-connected air conditioner.

[0050] Through the above technical solution, four lifting drive rods 201 are provided to provide power for the lifting of the foreign machine of the multi-connected air conditioner, so as to ensure the stability during lifting. When in use, the control circuit or pipeline of the lifting drive rod 201 and the power cord of the foreign machine of the multi-connected air conditioner are simultaneously led to the ground through the embedded pipe for convenient control.

[0051] The provided connectors 202 are used to connect and support the foreign machine support platform 203, so as to drive the foreign machine of the multi-connected air conditioner to lift inside the concrete support 101 through the expansion and contraction of the lifting drive rod 201, for the convenience of installing and maintaining the foreign machine of the multi-connected air conditioner.

[0052] Specifically, a gap is left between the bottom of the foreign machine support platform 203 and the top of the support boss 104, and several threaded holes for fixing the multi-hole air conditioner foreign machine are provided on the foreign machine support platform 203.

[0053] Through the above technical solution, a gap is left between the bottom of the foreign machine support platform 203 and the top of the support boss 104, so that a gap is left between the bottom of the foreign machine of the multi-connected air conditioner and the support boss 104, to improve the safety of the foreign machine of the multi-connected air conditioner in rainy weather and avoid the long-term immersion of the foreign machine of the multi-connected air conditioner by moist water when it gets damp.

[0054] Several threaded holes are provided on the top of the foreign machine support platform 203, so that the foreign machine of the multi-connected air conditioner can be conveniently installed and fixed, improving the stability of the foreign machine of the multi-connected air conditioner and avoiding the shaking and overturning of the foreign machine of the multi-connected air conditioner during the lifting process.

[0055] Specifically, a sealing cover 204 is fixedly connected to the top of the lifting drive rod 201. The sealing cover 204 includes a cover body adapted to the diameter of the lifting opening 102. A canopy larger than the diameter of the lifting opening 102 is fixedly connected to the top of the cover body, and the top of the canopy is an arc surface.

[0056] An opening and closing skylight 2041 is installed in the middle of the sealing cover 204, and the opening and closing skylight 2041 opens upward.

[0057] Through the above technical solution, the provided sealing cover 204 is used to seal the opening of the lifting opening 102 to achieve waterproofness. When the top of the sealing cover 204 is an arc-shaped canopy, rainwater will flow to both sides through the top of the sealing cover 204, reducing the possibility of rainwater seeping in from the connection between the sealing cover 204 and the lifting opening 102.

[0058] Such as Figure 6As shown, the opening and closing skylight 2041 is provided. When the weather is good, the opening and closing skylight 2041 can be opened to improve the heat dissipation inside the device and achieve a better heat dissipation effect.

[0059] Moreover, the window in the sealing cover 204 is provided with cross bars for supporting the opening and closing skylight 2041, thereby enhancing the firmness of the opening and closing skylight 2041 when it is closed.

[0060] In this application document, the described opening and closing skylight 2041 is manually controlled and can be set as an electric window according to actual needs to further improve the convenience of use.

[0061] In order to achieve waterproofness, waterproof rubber rings are provided around the opening and closing skylight 2041.

[0062] During use, the concrete support 101 is set underground, and the multi-connected air conditioner outdoor unit can enter through the lifting port 102. At the same time, a return air mechanism 103 is set at the top of the concrete support 101. When the multi-connected air conditioner outdoor unit works, a large amount of heat is generated, making the inside of the concrete support 101 in a high-temperature and high-pressure state. According to the characteristics of air flow, hot air will flow towards the cold air direction. Therefore, the hot air flows out a large amount through the return air mechanism 103 on one side and the cold air is inhaled through the return air mechanism 103 on the other side, achieving the effect of improving air exchange.

[0063] In order to further improve the heat dissipation effect, a ventilation fan 1031 is set inside the return air mechanism 103 for active heat dissipation. Its working mode is to intake air on one side and exhaust air on the other side, accelerating the air circulation speed.

[0064] And when the weather is good, the opening and closing skylight 2041 can be actively opened to obtain a better heat dissipation effect, and the opening and closing skylight 2041 is closed in rainy days.

[0065] By setting the support boss 104 to increase the installation height of the multi-connected air conditioner outdoor unit and setting the outdoor unit support platform 203 to further improve the installation of the multi-connected air conditioner outdoor unit, accidental water seepage in the concrete support 101 is avoided from contacting the multi-connected air conditioner outdoor unit. At the same time, the sealing cover 204 is set to seal the lifting port 102 for waterproofing and rain protection, achieving the effect of protecting the multi-connected air conditioner outdoor unit.

[0066] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
