Description

Technical Field

[0001] This utility model belongs to the field of evaporative cooling air conditioning technology, specifically a chassis water tank for an evaporative cooling energy-saving air conditioner. Background Technology

[0002] Evaporative air conditioning is an air conditioning device that uses the principle of water evaporation to absorb heat and cool the air. When outdoor air enters the air conditioning unit, it first passes through the wet curtain. The water on the wet curtain absorbs heat from the air and evaporates, which lowers the air temperature and increases the humidity. Then the cooled air is sent into the room to achieve the purpose of cooling.

[0003] In existing evaporative air conditioners, the outdoor unit chassis is typically equipped with a water tank to store water for evaporative cooling, ensuring a continuous and stable water source during the evaporative cooling process. This keeps the wet curtains moist, allowing the water evaporation and heat absorption process to continue. However, after prolonged use, some dust and sand particles accumulate in the water. During subsequent circulation, the water pump sucks in these particles, causing impeller blockage and wear on the condenser's inner wall. This results in reduced lifespan and lower failure rate for the air conditioner, thus requiring improvement. Utility Model Content

[0004] To address the problems mentioned in the background section, this utility model provides a chassis water tank for an evaporative cooling energy-saving air conditioner.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chassis water tank for an evaporative cooling energy-saving air conditioner, comprising a water tank, a water circulation component provided on the outside of the water tank, and a drain valve provided on the outside or bottom of the water tank;

[0006] The water circulation component includes a baffle and an inlet pipe. The outer surface of the inlet pipe is connected to the inner wall of the water tank, and the inner side of the inlet pipe extends into the inner cavity of the water tank. The outer side of the baffle is movably engaged with the inner cavity of the water tank, and a filter screen is provided inside the baffle.

[0007] Preferably, the water circulation assembly includes a base plate, the outer side of which is connected to the outer wall of the air conditioner outdoor unit, a water pump is provided on the inner wall of the base plate, the outer side of the water pump is connected to a water inlet pipe, a drain pipe is provided on the top of the water pump, and the top of the drain pipe extends to the outside of the base plate.

[0008] Preferably, the top of the water tank is connected to the bottom of the outdoor unit of the air conditioner, and the water tank is manufactured using an integral molding process.

[0009] Preferably, the bottom cross-section of the water tank is smaller than the top cross-section, and the drain valve is located at the bottom outside the water tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model is equipped with a filter screen and a water tank. The design of the water tank facilitates the sedimentation of impurities in the water source to one side, and the sedimented impurities can be easily discharged through the drain valve. At the same time, when the water pump starts, water is drawn from the water source through the inlet pipe, and the filter screen filters the drawn water to prevent impurities from entering the water pump, avoiding damage to the equipment, thereby extending the service life of the air conditioner, ensuring the long-term stable operation of the air conditioning system, and preventing impurities from causing blockage of the water pump impeller and wear on the inner wall of the condenser. If the inner wall is damaged, water may enter the refrigeration system, rendering the main unit unusable. Attached Figure Description

[0020] 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.

[0021] Example 1

[0022] like Figures 1 to 4As shown, the first embodiment of the utility model provides a chassis water tank for an evaporative cooling energy-saving air conditioner, including a water tank 1, a water circulation component 3 is provided on the outside of the water tank 1, and a drain valve 2 is provided on the outside of the water tank 1 or at the bottom of the water tank.

[0023] The water circulation component 3 includes a baffle 305 and an inlet pipe 303. The outer surface of the inlet pipe 303 is connected to the inner wall of the water tank 1. The inner side of the inlet pipe 303 extends into the inner cavity of the water tank 1. The outer side of the baffle 305 is movably engaged in the inner cavity of the water tank 1. A filter screen 306 is provided inside the baffle 305.

[0024] When the water circulation component 3 is running, water is drawn from the water tank 1 through the water inlet pipe 303 and then transferred to the condenser in the indoor unit of the air conditioner. The evaporation of water carries away the heat from the condenser, enhancing the heat dissipation effect of the condenser. Furthermore, the water inside the water tank 1 is filtered by a baffle 305 and a filter screen 306, preventing dust, sand, and other dirt from being drawn into the indoor unit of the air conditioner. This prevents dust, sand, and other dirt from participating in the water circulation, greatly extending the service life of the air conditioner structure and preventing the water pump 302 from becoming clogged, thus bringing convenience to the operator.

[0025] Example 2

[0026] like Figure 2 and Figure 3 As shown, this embodiment includes the features of embodiment 1. The distinguishing technical feature is that the water circulation component 3 includes a base plate 301. The outer side of the base plate 301 is connected to the outer wall of the air conditioner outdoor unit. A water pump 302 is provided on the inner wall of the base plate 301. The outer side of the water pump 302 is connected to the water inlet pipe 303. An inlet and outlet circulation water pipe 304 is provided on the top of the water pump 302. The top of the inlet and outlet circulation water pipe 304 extends to the outside of the base plate 301.

[0027] By connecting the other end of the inlet and outlet circulating water pipes 304 to the condenser of the indoor unit of the air conditioner, when the water pump 302 is running, the water source filtered by the filter screen 306 inside the water tank 1 is drawn through the inlet water pipe 303, so as to prevent dust, sand and other dirt from being sucked into the water pump 302 and causing the impeller to be blocked, ensuring that the impeller can rotate smoothly and maintain the normal performance of the air conditioner.

[0028] The top of water tank 1 is connected to the bottom of the outdoor unit of the air conditioner, and water tank 1 is made using a one-piece molding process.

[0029] Because water tank 1 is made in one piece, it eliminates the need for splicing multiple parts. Splicing multiple parts not only involves complex connection processes but also easily leads to loosening at the joints. By integrating water tank 1 into a single unit, the cumbersome splicing process is eliminated, greatly simplifying the overall structure and making the chassis structure clearer and more compact. At the same time, the one-piece molding reduces the number of parts, lowers raw material procurement costs, and the simplified production process reduces labor costs and production time, thereby reducing overall costs and facilitating installation and production for operators.

[0030] Among them, the bottom section of water tank 1 is smaller than the top section, and the drain valve 2 is located at the bottom outside the water tank 1 or at the bottom of the water tank;

[0031] Because the top cross-section of water tank 1 is large, the inner side of water tank 1 is sloping, which facilitates the sedimentation of dust, sand and other dirt in the water source. It also facilitates the sliding of dirt adsorbed on the inner wall to the bottom. At the same time, opening the drain valve 2 allows the sedimented dust, sand and other dirt to be discharged, so that the dirt can be discharged from the machine more effectively. In addition, the large size of water tank 1 increases the contact area and time between the coolant and the heat exchanger, making the entire heat dissipation process more efficient and ensuring that the air conditioner can effectively dissipate heat under different ambient temperatures and operating loads.

[0032] Among them, the bottom of water tank 1 is inclined, and the side of the bottom of water tank 1 near the drain valve 2 is lower;

[0033] By setting the bottom of water tank 1 to be inclined, achieving a situation where one side is higher than the other, the inclined design allows the sediment to flow naturally to the lower position under the action of gravity, making it easier to clean and reducing the wear of sediment on other components inside the chassis. At the same time, the drain valve 2 opens when the sediment settles to a certain extent, draining the water containing sediment and dirt, keeping the inside of the chassis clean, ensuring the cleanliness of the circulating water, and maintaining the good operating condition of the air conditioning water circulation system.

[0034] Among them, the water inlet pipe 303 is located higher than the bottom of the water tank 1;

[0035] When the water pump 302 starts, it generates suction. When the inlet pipe 303 is close to the bottom of the chassis, it is easy to suck the dirt that has settled at the bottom into the pump body. However, the higher position of the inlet pipe 303 can prevent the dirt from being sucked into the bottom of the chassis, protect the impeller of the water pump 302 from wear, extend the service life of the condenser, ensure the long-term stable operation of the air conditioning system, and reduce the failure rate of the water pump 302.

[0036] The water tank 1 has grooves on both its inner and outer sides;

[0037] By setting grooves on the inner and outer sides of the water tank 1, the structural strength of the water tank 1 is increased. The grooves can disperse external forces, making the water tank 1 less prone to deformation when subjected to greater pressure, thus improving the durability of the water tank 1 and reducing malfunctions such as water leakage caused by damage to the water tank 1.
