Technical Field
[0001] This utility model relates to the field of heat pump water heater technology, and in particular to a circulating heat pump water heater for swimming pools that is easy to maintain. Background Technology
[0002] With the improvement of people's living standards, swimming pools have been widely used in homes, hotels, fitness centers, and other places. As a crucial device for heating and circulating pool water, the performance and ease of maintenance of circulating heat pump water heaters are paramount. Traditional circulating heat pump water heaters for swimming pools have certain design flaws, resulting in numerous inconveniences in heat pump maintenance, especially in the maintenance of the cooling fan.
[0003] In existing circulating heat pump water heaters for swimming pools, the cooling fan is typically tightly connected to the heat pump casing, installed in a fixed position inside the heat pump, and secured with screws or other fasteners. When the cooling fan malfunctions or needs to be cleaned of debris from the fan blades, maintenance personnel often need to disassemble the entire heat pump casing. This process is not only tedious and complex but also requires specialized tools and skilled techniques, making it time-consuming and labor-intensive. During disassembly, there is also a risk of accidental damage to the heat pump casing and other internal components, increasing maintenance costs and equipment downtime.
[0004] Furthermore, due to the compact internal structure of heat pumps and the relatively concealed installation location of the cooling fan, the limited operating space during maintenance causes significant inconvenience for maintenance personnel, severely impacting maintenance efficiency and the normal operation of the equipment. Therefore, developing a circulating heat pump water heater for swimming pools that allows for quick disassembly of the cooling fan without disassembling the entire heat pump casing is of significant practical importance for improving equipment maintenance convenience, reducing maintenance costs, and ensuring the normal use of the swimming pool. Utility Model Content
[0005] The problem this invention aims to solve is to provide a swimming pool circulating heat pump water heater that is easy to maintain. By optimizing the installation structure of the cooling fan, the cooling fan can be quickly disassembled and maintained without disassembling the entire heat pump casing, simplifying maintenance steps, improving maintenance efficiency, reducing maintenance costs, shortening equipment downtime, and ensuring the normal operation and service life of the swimming pool circulating heat pump water heater.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a circulating heat pump water heater for swimming pools that is easy to maintain, comprising a heat pump body, a sliding groove provided inside the heat pump body, two U-shaped sliding frames slidably connected to the sliding groove, a fan assembly module installed between the two U-shaped sliding frames, a protective net and a cooling fan provided inside the fan assembly module, a fixing mechanism provided on the front of the heat pump body, the fixing mechanism comprising a strip-shaped square tube and a fixing plate, the strip-shaped square tube being installed on the front of the heat pump body, the fixing plate being installed on the front of the fan assembly module, a limit rod slidably connected inside the strip-shaped square tube, and the limit rod being slidably connected to the inside of the fixing plate.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0021] like Figures 1 to 4As shown, a maintenance-friendly circulating heat pump water heater for swimming pools includes a heat pump body 1. The heat pump body 1 has a sliding groove 2 inside. Two U-shaped sliding frames 3 are slidably connected to the sliding groove 2. A fan assembly module 4 is installed between the two U-shaped sliding frames 3. The fan assembly module 4 has a protective mesh 6 and a cooling fan 7 inside. The fan assembly module 4 is slidably connected to the inside of the sliding groove 2. A shock-absorbing rubber pad 5 is installed on the back of the fan assembly module 4. The shock-absorbing rubber pad 5 is slidably connected to the inside of the sliding groove 2. The side of the shock-absorbing rubber pad 5 away from the fan assembly module 4 contacts the inner wall of the heat pump body 1. A handle 8 is installed on the front of the fan assembly module 4.
[0022] The groove 2 inside the heat pump body 1 provides a sliding track for the fan assembly module 4. Two U-shaped sliding frames 3 are slidably connected to the groove 2, forming lateral support for the fan assembly module 4. The shock-absorbing rubber pad 5 reduces fan vibration through elastic deformation.
[0023] A fixing mechanism 9 is provided on the front of the heat pump entity 1. The fixing mechanism 9 includes a strip-shaped square tube 901 and a fixing plate 904. The strip-shaped square tube 901 is installed on the front of the heat pump entity 1, and the fixing plate 904 is installed on the front of the fan assembly module 4. A limit rod 903 is slidably connected inside the strip-shaped square tube 901. The limit rod 903 is slidably connected to the inside of the fixing plate 904. A sliding plate 902 is slidably connected to the inner wall of the strip-shaped square tube 901. The sliding plate 902 is installed at the bottom end of the limit rod 903. A spring 905 is installed on the bottom surface of the sliding plate 902. The bottom end of the spring 905 is installed on the inner bottom wall of the strip-shaped square tube 901. A sliding rod 906 is sleeved inside the spring 905. The sliding rod 906 is slidably connected to the inside of the strip-shaped square tube 901. An installation block 907 is installed at the bottom end of the sliding rod 906. A pull rod 908 is fixedly connected to the front of the installation block 907.
[0024] The fixing plate 904 is fixed to the front of the fan assembly module 4, and its interior has a socket that matches the limiting rod 903.
[0025] By setting up the slide 2, U-shaped slide frame 3 and fixing mechanism 9, the fan assembly module 4 can slide along the slide 2 and can be quickly locked and unlocked by the fixing mechanism 9. When maintenance is required, simply pull the lever 908 to unlock it and pull out the fan assembly module 4 along the slide 2 for inspection or cleaning. There is no need to disassemble the entire heat pump housing, which simplifies the maintenance steps, reduces maintenance time, lowers maintenance costs, avoids the risk of damage to the heat pump housing and internal components caused by disassembling the housing, and improves the convenience of maintenance and the operating efficiency of the equipment.
[0026] Working principle: When it is necessary to release the lock of the fixing mechanism 9, pull down the lever 908 to move the mounting block 907 and the slide bar 906 downwards. The slide plate 902 compresses the spring 905, causing the limit rod 903 to be pulled out of the insertion hole of the fixing plate 904, thus releasing the lock on the fan assembly module 4. Hold the handle 8 and pull the fan assembly module 4 outwards horizontally along the slide groove 2. The module is completely detached from the heat pump body 1. At this time, the cooling fan 7 integrated in the fan assembly module 4 can be directly inspected or the protective mesh 6 can be cleaned without disassembling the heat pump housing.
[0027] When the cooling fan 7 needs to be installed and reset, pull down the lever 908 to keep the limit plug 903 in a downward position to avoid blocking the module from being pushed in. Then, align the fan assembly module 4 with the slide groove 2 and push the handle 8 to make the module slide in along the track.
[0028] When the fan assembly module 4 slides into the bottom of the slide groove 2, the pull rod 908 is released, the spring 905 returns to its original deformation and pushes the slide plate 902 upward, causing the top of the limit rod 903 to insert into the insertion hole of the fixing plate 904, thus locking the module. At this time, the shock-absorbing rubber pad 5 is tightly fitted to the inner wall of the heat pump body 1, achieving sealing and shock absorption.
[0029] After the module is installed, the shock-absorbing rubber pad 5 squeezes and fills the gap between the module and the inner wall of the heat pump body 1, reducing the vibration noise of the cooling fan 7 during operation and preventing dust and moisture from entering the heat pump.
[0030] The protective mesh 6 inside the fan assembly module 4 covers the top of the cooling fan 7, blocking debris from entering the fan blades, preventing foreign objects from getting tangled and causing malfunctions, and ensuring the safety of maintenance personnel.
[0031] In existing technologies, maintaining the cooling fan requires disassembling the entire heat pump housing. This invention, through the sliding engagement of the sliding groove 2 and the U-shaped sliding frame 3, and the quick-locking structure of the fixing mechanism 9, enables maintenance of the cooling fan 7 without disassembling the housing. This design reduces disassembly steps, avoids damage to internal heat pump components, shortens maintenance time, reduces maintenance costs, and meets the high-efficiency operation requirements of swimming pool equipment.
