Description

TECHNICAL FIELD

[0001] The present application relates to the field of water heaters, in particular to a wall-mounted heat pump water heater convenient to install. BACKGROUND

[0002] The heat pump water heater, also known as an air source heat pump water heater, is a new type of air energy water heater. Its working principle is very similar to that of an air conditioner. A small amount of electric energy is used to drive the compressor to operate. The high-pressure liquid state working medium is evaporated into a gaseous state in the evaporator after passing through the expansion valve and absorbs a large amount of heat energy from the air. The gaseous working medium is compressed by the compressor into a high-temperature and high-pressure liquid state, and then enters the condenser to release heat and heat the water. This process is repeated continuously to achieve heating. Compared with electric water heaters, heat pump water heaters are more energy-efficient. The wall-mounted heat pump water heater is an air energy water heater installed on the facade of a building. It can effectively save floor space and is suitable for high-rise building installation. The common wall-mounted heat pump water heater needs to be installed on the facade of the building with a bracket, and a bracket needs to be installed for the water tank and the fan respectively. At the same time, the bracket needs to be lifted for bolt fixation during installation. Not only is it laborious, but also the efficiency is low. At the same time, the installer also needs to use bolts to fix the fan and the water heater above the bracket, which not only takes a long time to operate, but also is difficult to ensure the stability of the high-cylindrical water tank, causing inconvenience.

The spacer slide groove 49 is connected to the inner slide groove 46. The head of the spacer block 48 extends out of the spacer slide groove 49 and is connected to the rear end face of the push block 50.

[0040] It should be noted that this invention is an easy-to-install wall-mounted heat pump water heater. In actual use, firstly, install the bottom bracket 5 on the exterior of the building. Then, attach the mounting plate 16 on the vertical side of the bottom bracket 5 tightly to the wall. Next, use the mounting screws 18 to install and fix it, ensuring the bottom bracket 5 is stable. Then, install the base plate 2 on top, aligning the positioning holes 20 on both sides of the base plate 2 with the positioning posts 19 on the top of the bottom bracket 5, until the bottom of the base plate 2 is flush with the upper surface of the bottom bracket 5. Then, locate the pair of rectangular clamping plates 7 on the upper surface of the base plate 2 and push them outwards. The rectangular clamping plates 7 drive the first slider 22 below to slide along the first horizontal column 25, and during sliding, press the annular pressure plate 27 on the outer ring of the first horizontal column 25. The annular pressure plate 27 is also pressed along... The first horizontal column 25 slides along the rectangular clamp 7, compressing the connected first spring 28 during the sliding motion. As the rectangular clamp 7 moves, it also moves the upper horizontal plate 8 and the side clamp 9. Then, the two side clamps 9 are located and pushed outwards simultaneously, causing the connected second slider 29 to slide along the second horizontal column 32. During this sliding motion, the slider compresses the movable pressure plate 34 on the outer ring of the second horizontal column 32, causing the movable pressure plate 34 to also move along the second horizontal column 32. During this movement, the movable pressure plate 34 compresses the connected second spring 35. After the two side clamps 9 are pulled apart, the air-source fan 4 can be placed between the fixed clamp 6 and the rectangular clamp 7. Then, the rectangular clamp 7 is released, allowing it to move under the elastic force. The springback mechanism, in conjunction with the fixing clamp 6, clamps and secures both sides of the air source fan 4. At this time, the side clamp 9 is located at the front and rear of one end of the air source fan 4. Then, the side clamp 9 can be slowly released, allowing it to gradually contract under the action of elasticity, eventually adhering to the front and rear end faces of the air source fan 4, thereby clamping and securing the front and rear ends of the air source fan 4. Next, locate the arc-shaped sleeve 10 above the base plate 2, and then place the bottom of the heating water tank 1 between the arc-shaped sleeve 10. Then, locate the first straight rod 12, the second straight rod 13, and the limiting frame plate 14 at the top of the upright rod 11. Then, pull the second straight rod 13 outward, causing it to drive the connected telescopic round rod 51 to move outward. The telescopic round rod 51 drives the limiting round plate 54 to move, and when the limiting round plate 54 moves, it squeezes the connected third spring. 36, causing it to be compressed by force. When the second straight rod 13 moves, it also drives the connected limiting frame plate 14 to move outward. After the limiting frame plate 14 is pulled open, the push block 50 on the outside of the first straight rod 12 is found and pushed. The push block 50 drives the connected spacer block 48 and the limiting slider 47 to move. The limiting slider 47 drives the connected extension cable 44 to move. The extension cable 44 drives the connected front partition plate 41 to move backward. When the front partition plate 41 moves, it squeezes the fourth spring 43 behind it, causing it to be compressed by force. At the same time, the front partition plate 41 drives the connected positioning protrusion 38 to move, causing the head of the positioning protrusion 38 to disengage from the positioning groove 39. Then, the first straight rod 12 can be pushed up and down, thereby adjusting the height of the connected second straight rod 13 and the limiting frame plate 14.After adjusting the height of the heating water tank 1 to a suitable level, the push block 50 can be released, allowing the positioning protrusion 38 to spring back and enter the corresponding positioning groove 39. Then, the limiting frame plate 14 and the second straight rod 13 can be released, allowing them to move inward under elastic force, ultimately securing the top of the heating water tank 1 in a circular motion to improve its stability.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
