Description

Technical Field

[0001] This utility model relates to the field of air conditioning unit technology, specifically a direct expansion air conditioning unit. Background Technology

[0002] In simple terms, a direct expansion air conditioning unit is a unit with its own compressor. In its refrigeration system, the liquid refrigerant evaporates (expands) directly in its evaporator coil to absorb heat from the air outside the coil (that is, the air inside the air-conditioned room) to achieve cooling. Therefore, a filter plate needs to be installed inside the unit to filter the air inside to ensure the normal operation of its internal components.

[0003] Most existing filtration devices in generator sets only use simple filter screens to filter the air entering the unit for dust prevention. Over time, a large amount of dust will accumulate on the surface of the filter screen. Since this dust is not fixed on the filter screen, when the filter screen is disassembled and cleaned, it will inevitably shake, causing the dust to fall into the unit and cause internal pollution. In severe cases, it may affect the operation of the unit.

[0004] The patent document with publication number CN217503848U discloses a direct expansion heat pump air conditioning unit, including a main body, an air inlet plate, a return air duct, a slot, a slot, a primary filter plate, a secondary filter plate, and an air outlet. The main body has a slot, and slots are opened on the left and right sides of the slot. The primary filter plate and the secondary filter plate are respectively inserted into the slot. The top of the outer frame of the primary filter plate and the secondary filter plate is provided with a fixed top cover, which is fastened to the slot by a left buckle structure and a right buckle structure.

[0005] However, while direct expansion heat pump air conditioning units allow for easy disassembly, cleaning, and installation of the filter plates, the filter plate surface lacks any protective measures. Furthermore, the unit lacks a buffer mechanism during operation, which may generate significant noise and cause damage to internal equipment due to excessive vibration, resulting in losses. Therefore, a direct expansion air conditioning unit is needed. Utility Model Content

[0006] The purpose of this utility model is to provide a direct expansion air conditioning unit to solve the problems mentioned in the background art regarding the operation of direct expansion air conditioning units.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a direct expansion air conditioning unit, comprising a unit body and a disassembly box disposed on one side of the unit body, wherein a disassembly mechanism is disposed inside the disassembly box, and a buffer mechanism is disposed at the bottom of the unit body;

[0008] The disassembly mechanism includes a second telescopic rod, a return spring, a filter plate, a limiting plate, a fixing block, and a push plate. The second telescopic rod is fixedly connected to the bottom of the inner wall of the disassembly box. The return spring is movably connected to the outside of the second telescopic rod. The push plate is fixedly connected to the top of the second telescopic rod. The filter plate is located on the top of the push plate. The limiting plate is movably connected to the top of the disassembly box. The fixing block is fixedly connected to the top of the disassembly box.

[0009] Preferably, the filter plate is T-shaped on both sides, and the inner wall of the disassembly box is provided with a T-shaped groove that mates with the filter plate. The filter plate is slidably connected to the inner wall of the disassembly box. During installation, the bottom of the filter plate contacts the top of the push plate. During disassembly, the push plate applies a pushing force to the filter plate to push it out.

[0010] Preferably, the limiting plate is slidably connected between the disassembly box and the fixing block. The limiting plate is mainly used to restrict the filter plate and clamp the installed filter plate.

[0011] Preferably, the filter plate is detachable. After the limiting plate is pulled out, the restriction on the filter plate is released, and the filter plate moves upward under the pushing force of the push plate. At this time, the filter plate can be easily disassembled.

[0012] Preferably, the buffer mechanism includes a base, sound-absorbing cotton, a damping plate, a telescopic rod, a buffer spring, and a foot bracket. The base is located at the bottom of the main body of the unit. The sound-absorbing cotton and the damping plate are both fixedly connected to the top of the base. The telescopic rod is fixedly connected to the top of the base. The buffer spring is movably connected to the outside of the telescopic rod. The foot bracket is fixedly connected to the bottom of the base. Four foot brackets are evenly distributed at the bottom of the base.

[0013] Preferably, the bottom of the main body of the unit is fixedly connected to a baffle that cooperates with the top of the base. When the main body of the unit is located on the top of the base, it is in an active state. At this time, the baffle limits the main body of the unit to prevent the main body of the unit from tilting.

[0014] Preferably, the sound-absorbing cotton is distributed in a ring around the top of the unit body, and the sound-absorbing cotton surrounds the main buffer structure inside the unit body, which can effectively reduce the noise generated during buffering.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This direct expansion air conditioning unit, through its disassembly mechanism, allows dust and debris from the outside of the unit to enter the unit after it has been operating for a period of time, affecting the efficiency of the internal equipment. The filter plate can prevent dust and debris from entering the unit. After pulling open the limit plate, the restriction on the filter plate is released, and the compressed return spring generates a rebound force at the bottom of the push plate, which pushes the filter plate out, making it easy to disassemble and clean the filter plate, thus ensuring the filtration effect of the filter plate.

[0017] 2. This direct expansion air conditioning unit, through its buffer mechanism, addresses the vibration and noise inherent in its internal compressor. Upon installation, the unit is subjected to pressure, compressing the buffer springs. The compressed springs then exert a rebound force on the bottom of the unit, offsetting some of the potential energy generated by the vibration. When the unit comes into contact with the top of the damping plate, the plate deforms, generating friction between its molecules, thus producing damping force to further offset the vibration. The sound-absorbing cotton at the top of the base absorbs noise generated at the bottom of the unit, reducing noise while simultaneously protecting the internal equipment.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model provides a technical solution:

[0026] Example 1:

[0027] A direct expansion air conditioning unit includes a unit body 1 and a disassembly box 2 disposed on one side of the unit body 1, wherein a disassembly mechanism is provided inside the disassembly box 2.

[0028] The disassembly mechanism includes a second telescopic rod 201, a return spring 202, a filter plate 203, a limiting plate 204, a fixing block 205, and a push plate 206. The second telescopic rod 201 is fixedly connected to the bottom of the inner wall of the disassembly box 2. The return spring 202 is movably connected to the outside of the second telescopic rod 201. The push plate 206 is fixedly connected to the top of the second telescopic rod 201. The filter plate 203 is located on the top of the push plate 206. The filter plate 203 is detachable. After the limiting plate 204 is pulled out, the restriction on the filter plate 203 is released. The filter plate 203 moves upward under the pushing force of the push plate 206. At this time, the filter plate 203 can be easily disassembled. The filter plate 203 has T-shaped sides. The inner wall of the disassembly box 2 has T-shaped grooves that mate with the filter plate 203. The filter plate 203 is slidably connected to the inner wall of the disassembly box 2. During installation, the bottom of the filter plate 203 contacts the top of the push plate 206. During disassembly, the push plate 206 applies a pushing force to the filter plate 203, pushing it out. A limiting plate 204 is movably connected to the top of the disassembly box 2. The limiting plate 204 is slidably connected between the disassembly box 2 and the fixing block 205. The limiting plate 204 is mainly used to restrict the filter plate 203, securing the installed filter plate 203. The fixing block 205 is fixedly connected to the top of the disassembly box 2. When the main body 1 of the unit is dissipating heat, dust and debris from the outside of the main body 1 may enter the main body 1, affecting the working efficiency of the internal equipment. The filter plate 203 can block dust and debris in the air from entering the main body 1. After the limit plate 204 is pulled open, the restriction on the filter plate 203 is released. The compressed return spring 202 will generate a rebound force acting on the bottom of the push plate 206, so that the push plate 206 pushes out the filter plate 203. The filter plate 203 can be easily disassembled and cleaned.

[0029] Example 2:

[0030] Based on Embodiment 1, a buffer mechanism is provided at the bottom of the unit body 1. The buffer mechanism includes a base 101, sound-absorbing cotton 102, a damping plate 103, a telescopic rod 104, a buffer spring 105, and a foot bracket 106. The base 101 is located at the bottom of the unit body 1, and a baffle that cooperates with the top of the base 101 is fixedly connected to the bottom of the unit body 1. When the unit body 1 is on top of the base 101, it is in a movable state. At this time, the baffle limits the unit body 1 to prevent it from tilting. The sound-absorbing cotton 102 and the damping plate 103 are both fixedly connected to the top of the base 101. The sound-absorbing cotton 102 is distributed in a ring around the top of the unit body 1, surrounding the main buffer structure inside the unit body 1, which can effectively reduce the noise generated during buffering. Telescopic rod 104 is fixedly connected to the top of base 101, buffer spring 105 is movably connected to the outside of telescopic rod 104, and foot bracket 106 is fixedly connected to the bottom of base 101. Four foot brackets 106 are evenly distributed on the bottom of base 101. When the main body 1 of the unit is working, it vibrates. The buffer spring 105 is compressed by force. The compressed buffer spring 105 generates a rebound force that acts on the bottom of the main body 1 of the unit, offsetting part of the potential energy generated by the vibration. When the main body 1 of the unit comes into contact with the top of the damping plate 103, the damping plate 103 deforms, thereby generating a damping force that offsets part of the potential energy generated by the vibration. The sound-absorbing cotton 102 set on the top of base 101 absorbs the noise generated inside the bottom of the main body 1 of the unit, reducing noise while buffering.

[0031] Working principle:

[0032] First, through the buffer mechanism, since the unit body 1 has a built-in compressor, it will inevitably generate vibration and noise. When the unit body 1 is installed, the unit body 1 is under pressure. At this time, the buffer spring 105 is compressed. The compressed buffer spring 105 will generate a rebound force under its own restoring force. The rebound force acts on the bottom of the unit body 1, offsetting part of the potential energy generated by the vibration. When the unit body 1 contacts the top of the damping plate 103, the damping plate 103 deforms and friction is generated between the molecules, thereby generating a damping force, offsetting part of the potential energy generated by the vibration. The sound-absorbing cotton 102 set on the top of the base 101 will absorb the noise generated at the bottom of the unit body 1. While buffering, the noise is reduced, and the buffer can protect the internal equipment of the unit body 1.

[0033] Furthermore, through the designed disassembly mechanism, after the internal equipment of the unit body 1 has been working for a period of time, while the internal heat dissipation of the unit body 1 is being carried out, dust and debris from the outside of the unit body 1 may enter the unit body 1, affecting the working efficiency of the internal equipment. The filter plate 203 can block dust and debris in the air from entering the unit body 1. After the limit plate 204 is pulled open, the restriction on the filter plate 203 is released. The compressed return spring 202 will generate a rebound force under its restoring force. The rebound force acts on the bottom of the push plate 206, causing the push plate 206 to push out the filter plate 203. The filter plate 203 can be easily disassembled and cleaned, ensuring the filtration effect of the filter plate 203.
