Description

Technical Field

[0001] This utility model relates to the field of air conditioning accessories technology, specifically to heat pump air conditioner evaporators. Background Technology

[0002] Air source heat pump driven air conditioners have been widely used and are very popular. Their heating principle is to achieve heating through energy transfer. When the air conditioner is heating, the evaporator in the outdoor unit acts as a "heat collector" to absorb low-grade heat from the outdoor environment (even low-temperature environments contain usable heat). The refrigerant that has absorbed heat is compressed and heated by the compressor, and then sent to the indoor condenser to release heat, ultimately achieving the effect of heating the room.

[0003] However, air conditioner evaporators usually require multiple bolts to be fixed to the outdoor unit. Installation and disassembly require the use of other tools to tighten the bolts one by one, making the installation and disassembly process of the evaporator quite cumbersome and resulting in extremely low efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a heat pump air conditioner evaporator to solve the problem mentioned in the background art that air conditioner evaporators usually need to be fixed to the outdoor unit of the air conditioner with multiple bolts, and installation and disassembly require the use of other tools to tighten the bolts in sequence, which makes the installation and disassembly process of the evaporator cumbersome and results in extremely low efficiency of evaporator installation and disassembly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat pump air conditioner evaporator, comprising:

[0006] Air conditioner casing;

[0007] A lock cover, which is symmetrically and detachably installed at the top and bottom of the air conditioner housing;

[0009] Quick-installation components are symmetrically arranged inside the lock cover and are used for quick assembly and disassembly of the evaporator.

[0010] The quick-installation assembly includes locking claws, two of which are symmetrically arranged. A return spring is fixedly installed on the side of the locking claws that are far apart from each other. A fixing plate is fixedly installed on the other end of the return spring. A push plate is rotatably installed on the same side of each locking claw. A push frame is rotatably installed on the other end of the push plate. A receiving cross plate is fixedly installed on the other side of the push frame.

[0011] A connecting frame is provided on both sides of the evaporator. A connecting arm is symmetrically and rotatably provided on one side of the connecting frame. An end joint is rotatably provided at the other end of the connecting arm. A plug is fixedly provided at the bottom end of the end joint. A locking plate is fixedly provided at the other end of the plug.

[0013] By adopting the above technical solution, the components can work together stably.

[0014] Preferably, a sliding shell is fixedly provided on the side of the connecting frame closer to the evaporator, and the sliding shell is slidably disposed on one side of the evaporator. A push-pull rod is fixedly provided on the side of the connecting frame away from the evaporator.

[0015] The above technical solution makes the connecting frame more stable during use.

[0016] Preferably, the connecting arm is inclined.

The pull-back spring is fixedly arranged at the top and bottom of one side of the evaporator, and the insertion post is slidably arranged inside the sliding hole.

[0019] By adopting the above technical solution, the opening of the sliding hole facilitates the sliding of the insertion post.

[0020] Preferably, a first slot is provided on one side of the lock cover, which corresponds to the receiving plate, and a second slot is provided on one side of the air conditioner housing and evaporator, which corresponds to the push-pull rod.

[0021] Using the above technical solution, when installing the evaporator, a hand can be inserted into the second slot to pull or push the push-pull rod, allowing the connecting bracket to move and facilitating the movement of other components. When disassembling the evaporator, fingers can be inserted into the first slot, such as the thumb and forefinger, with the two fingers pressing against the receiving cross plate, allowing the receiving cross plate to be pushed.

[0030] 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.

[0031] Please see Figure 1-5This utility model provides a technical solution: a heat pump air conditioner evaporator, including: an air conditioner housing 1, a locking cover 2, the locking cover 2 being symmetrically and detachably disposed at the top and bottom of the air conditioner housing 1, an evaporator 3, the evaporator 3 being embedded in one side of the air conditioner housing 1, and a quick-installation assembly 4, the quick-installation assembly 4 being symmetrically disposed inside the locking cover 2, the quick-installation assembly 4 being used for quick disassembly and assembly of the evaporator 3, the quick-installation assembly 4 including locking claws 401, two locking claws 401 being symmetrically disposed, a return spring 402 being fixedly disposed on the side of the locking claws 401 that is far apart from each other, a fixing plate 403 being fixedly disposed on the other end of the return spring 402, a push connecting plate 405 being rotatably disposed on the same side of the locking claws 401, a push connecting frame 406 being rotatably disposed on the other end of the push connecting plate 405, and a receiving cross plate 407 being fixedly disposed on the other side of the push connecting frame 406.

[0032] In this embodiment, when the locking platform 507 contacts and separates from the locking claw 401, the locking platform 507 can be locked, allowing for quick installation of the evaporator 3. When disassembling the evaporator 3, the two receiving horizontal plates 407 can be pushed simultaneously from both sides. Pushing the receiving horizontal plates 407 causes them to move away from each other. This movement of the receiving horizontal plates 407 moves the pusher frame 406, and the angle between the pusher plates 405 gradually increases under the action of the pusher frame 406. This causes the locking claws 401 connected to the pusher plates 405 to move away from each other, allowing the locking claws 401 to leave the locking platform 507. The locking platform 507 then automatically returns to its original position, disengaging from the locking range of the locking claws 401, thus achieving the unlocking effect. This process does not require the use of multiple bolts or additional tools, preventing tools from colliding with the fins in the evaporator 3 and causing damage. This provides some protection for the evaporator 3 and improves the efficiency of its disassembly and assembly.

[0033] Furthermore, the lock cover 2 is detachable, so both the lock cover 2 and the quick-release component 4 can be recycled, saving resources.

[0034] It should be noted that a slope is provided on one side of the top of the locking claw 401, a guide rail 404 is slidably provided at the bottom of the locking claw 401, an anti-detachment rail 408 is slidably provided at the bottom of the supporting horizontal plate 407, and the fixing plate 403, the guide rail 404 and the anti-detachment rail 408 are all fixedly provided on the inner side of the locking cover 2.

[0035] When the locking platform 507 comes into contact with the slope provided on one side of the top of the locking claw 401, the locking claw 401 can be separated. When the locking claw 401 is separated, it will slide along the guide slide rail 404. The guide slide rail 404 is set in an inverted trapezoidal shape as shown in the figure, so it can prevent the locking claw 401 from disengaging from the guide slide rail 404. When the horizontal plate 407 is moved, it can slide along the anti-disengagement slide rail 408. The anti-disengagement slide rail 408 is also set in an inverted trapezoidal shape, which plays an anti-disengagement role, thereby enabling the various components to cooperate stably.

[0036] Furthermore, the connecting frame 5 is disposed on both sides of the evaporator 3. A connecting arm 503 is symmetrically and rotatably disposed on one side of the connecting frame 5. An end seat 504 is rotatably disposed at the other end of the connecting arm 503. An insertion post 506 is fixedly disposed at the bottom end of the end seat 504. A locking platform 507 is fixedly disposed at the other end of the insertion post 506. Four sliding holes 301 are symmetrically disposed at the top and bottom ends of the evaporator 3. A pull-back spring 505 is fixedly disposed at the bottom end of the end seat 504. The pull-back spring 505 is fixedly disposed at the top and bottom ends of one side of the evaporator 3. The insertion post 506 is slidably disposed inside the sliding hole 301. A sliding shell 501 is fixedly disposed on the side of the connecting frame 5 closest to the evaporator 3. The sliding shell 501 is slidably disposed on the side of the evaporator 3. A push-pull rod 502 is fixedly disposed on the side of the connecting frame 5 away from the evaporator 3. The connecting arm 503 is inclined.

[0037] In this embodiment, when installing the evaporator 3, the push-pull rod 502 can be pulled, which will move the connecting bracket 5. Since the sliding shell 501 slides on one side of the evaporator 3, the connecting bracket 5 can move linearly. The movement of the connecting bracket 5 can drive the two connecting arms 503 to move, and the included angle between the two connecting arms 503 will gradually increase, thereby driving the insertion post 506 to slide inside the sliding hole 301. The upper insertion post 506 moves upward and the lower insertion post 506 moves downward. At the same time, the return springs 505 are all in a compressed state, which allows the locking platform 507 to separate the locking claw 401, so that the locking claw 401 locks the locking platform 507, thereby achieving the effect of quickly installing the evaporator 3.

[0038] Furthermore, the outer side of the locking platform 507 is provided with an annular slope, which facilitates the smooth separation of the locking claw 401 when the locking platform 507 comes into contact with the locking claw 401.

[0039] The compressed return spring 505 can provide a return force to the unlocked locking plate 507, thereby facilitating the disassembly of the evaporator 3.

[0040] The lock cover 2 has a first slot 201 on one side, which corresponds to the receiving plate 407. The air conditioner housing 1 and the evaporator 3 have a second slot 202 on one side, which corresponds to the push-pull rod 502.

[0041] When installing the evaporator 3, a hand can be inserted into the second slot 202 to pull or push the push rod 502, allowing the connecting bracket 5 to move and facilitating the movement of other components. When disassembling the evaporator 3, fingers, such as the thumb and forefinger, can be inserted into the first slot 201, with the two fingers pressing against the receiving plate 407, allowing the receiving plate 407 to be pushed. Since the air conditioner casing 1 is usually located outside, a mesh can be installed around the first slot 201 and the second slot 202. Because the air conditioner casing 1 is made of metal, the mesh can be magnetically fixed around the first slot 201 and the second slot 202 to prevent foreign objects from entering.

[0042] Working principle: When installing the evaporator 3, embed the evaporator 3 into one side of the air conditioner casing 1, and then pull the two push-pull rods 502 on both sides to move the connecting bracket 5. During this movement, the two connecting arms 503 move, and the included angle between the connecting arms 503 gradually increases, thereby moving the insertion post 506 and the locking platform 507. The upper insertion post 506 and locking platform 507 will move upwards, and the lower insertion post 506 and locking platform 507 will move downwards. Because the outer side of the locking platform 507 has an annular slope, the movement of the locking platform 507 will cause the locking claw 401 to separate, thus locking the locking platform 507. To achieve the effect of fixing the evaporator 3, when unlocking the evaporator 3, push the receiving horizontal plate 407 to both sides, so that the push connecting bracket 406 can drive the two push connecting plates 405 to move. The included angle between the two push connecting plates 405 will increase, thereby driving the two locking claws 401 away. The locking platform 507 can then disengage from the locking claws 401. This achieves the effect of quick disassembly and quick installation, and the process does not require additional tools, preventing tools from damaging the fins in the evaporator 3. Furthermore, the locking cover 2 and the quick-installation component 4 installed therein are a whole. This whole is detachable and can also be installed in other air conditioner housings 1 for use. This component can be recycled, saving resources.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
