Description

Technical Field

[0001] This utility model relates to the field of air conditioner outdoor unit defrosting technology, specifically a defrosting device for outdoor units of multi-split air conditioning systems. Background Technology

[0002] Multi-split air conditioning systems are one of the most widely used air conditioning systems in modern buildings. They are characterized by one outdoor unit connected to multiple indoor units through pipes, and each indoor unit can operate, stop, or even be controlled in groups or centrally.

[0003] For example, the defrosting device for the outdoor unit of a multi-split air conditioning system disclosed in Chinese Patent Publication No. CN221897879U has the following key technical features: a mounting block with a top groove on its top surface, a fan fixedly installed inside the top groove, and side grooves on the left and right sides of the mounting block connected to the top groove. In use, the mounting block can be initially fixed using suction cups. Then, by pulling the side plates, springs extend and the side plates are snapped into place on both sides of the outdoor unit. The device is installed using the spring tension. Air is drawn into the inner cavity through a telescopic shaft by turning on the fan, and then heated by heating wires to blow out hot air for defrosting the outdoor unit. A release hole is provided to cooperate with the nozzle to spray heated air, allowing the hot air to be blown over a wide area towards the outdoor unit to achieve the defrosting effect. Rubber pads are used to adhere to both sides of the outdoor unit, increasing the stability of the device after installation.

[0004] In the process of implementing this application, the inventors discovered that the technology has at least the following problems: Although the above technical solution can install the defrosting device by the tension of the spring, the side plates used for positioning on both sides will stick to the outside of the air conditioner outdoor unit, and the contact area with the air conditioner outdoor unit is too large, so the contact area cannot be effectively defrosted. Therefore, further improvements can be made. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides the following technical solution: a defrosting device for an outdoor unit of a multi-split air conditioning system, comprising an outdoor unit body, an air outlet on the front of the outdoor unit body, right-angle clamps at the four outer corners of the outdoor unit body, a support plate fixedly installed on the top of the right-angle clamps, a connecting plate between the two support plates, a pull-back assembly for connection between the connecting plate and the pull-back assembly, a tightening assembly for tensioning and positioning on the top of the support plate and the connecting plate, and a blowing defrosting assembly for blowing defrosting on one side of the front of the outdoor unit body corresponding to the air outlet.

[0006] As an optimization, the pull-back assembly includes a guide rod fixedly installed on the side of the support plate opposite to the connecting plate, and the other end of the guide rod is inserted into the inside of the connecting plate. A tension spring is fixedly installed between the support plate and the connecting plate, and the tension spring is sleeved on the outside of the guide rod. The tension springs on both sides can always pull the support plates on both sides closer to the connecting plate, thereby driving the right-angle clamping plates on both sides to tighten and clamp onto the side of the air conditioner outdoor unit body.
