Technical Field
[0001] This utility model relates to the field of air conditioner technology, and more specifically, to an evaporative air conditioner. Background Technology
[0002] Air conditioners are devices used to regulate indoor ambient temperature. Currently, when air conditioners on the market are working, the condenser in the outdoor unit generates a lot of heat when the indoor unit is in cooling mode. However, the condenser in the outdoor unit mainly relies on air cooling, which results in poor condenser cooling effect and high energy consumption. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide an evaporative air conditioner that can improve the cooling efficiency and cooling effect of the condenser, thereby reducing the energy consumption of the air conditioner.
[0004] This utility model provides an evaporative air conditioner, including an outdoor unit and an indoor unit. The outdoor unit includes an outdoor unit casing, a condenser, and a fan assembly. The condenser is fixed in the outdoor unit casing, and the fan assembly is fixed in the outdoor unit casing located in front of the condenser. First air inlets are provided on the rear side and both sides of the outdoor unit casing, and a first air outlet is provided on the front side of the outdoor unit casing. The outdoor unit also includes a water tank, a water tray, and a water curtain. The water tank is fixed on the inner bottom of the outdoor unit casing, and the water tray is fixed on the inner top of the outdoor unit casing. A water pump is fixed inside the water tank, and the outlet of the water pump is connected to the inlet of the water tray through a water pipe. The water curtain is fixed in the outdoor unit casing located behind the condenser. The upper end of the water curtain extends to the bottom of the water tray, and the lower end of the water curtain extends to the top of the water tank. Several water outlet holes are provided at the bottom of the water tray located above the water curtain.
[0005] By adopting the above structure, when the indoor unit is in cooling mode, the water pump can draw cooling water from the water tank and send it into the upper water pan. The cooling water entering the upper water pan can flow evenly to the upper end of the water curtain through several water outlets. Then, the cooling water can flow from top to bottom along the water curtain and cool it. The cooled water can then flow back into the water tank. Since the water curtain is located behind the condenser, when the fan assembly in the outdoor unit is working to allow air from the outside environment to enter through the first air inlet located behind the outdoor unit casing, the water curtain can pre-cool the air entering through the first air inlet. The cooled air can then flow through the condenser and cool it, thereby improving the cooling efficiency and effect of the condenser and reducing the energy consumption of the air conditioner.
[0006] In one possible implementation, a baffle is provided on the inner bottom of the upper water tank. A water storage cavity is formed on the inner side of the baffle, and a water distribution cavity is formed on the outer side of the baffle. Several overflow troughs are provided at intervals along the extension direction of the baffle at the upper end. A water inlet connector is provided at the bottom of the water storage cavity, forming the water inlet end of the upper water tank and connecting to the water outlet end of the water pump. Several water outlet holes are provided at the bottom of the water distribution cavity. With this structure, the water pump can draw cooling water from the water tank and cool the water... Water is fed into the water storage chamber through the inlet connector. When the water level in the storage chamber rises to the bottom of the overflow tank, the cooling water can overflow into the water distribution chamber through the overflow tank. The cooling water entering the water distribution chamber can flow evenly to the upper end of the water curtain through several outlet holes. Then, the cooling water can flow from top to bottom along the water curtain and cool the water curtain. The cooling water after cooling the water curtain can flow back into the water tank. During the process of the water pump continuously pumping the cooling water to the upper water plate, the cooling water can continuously and evenly cool the water curtain.
[0007] In one possible implementation, a support plate is fixed in the outdoor unit casing above the water tank. The upper end of the support plate has a cavity, and the lower end of the water curtain is inserted into the cavity. Several drainage holes are provided at the bottom of the cavity. By setting up the support plate and inserting the lower end of the water curtain into the cavity on the support plate, reliable support and limiting of the water curtain can be achieved. Furthermore, since several drainage holes are provided at the bottom of the cavity, the cooling water flowing down from the water curtain can be collected in the cavity and flow back to the water tank through the drainage holes. Under the action of the cavity, the cavity can collect the cooling water from the water curtain and prevent the cooling water from overflowing along the upper surface of the support plate to the outside of the support plate, thereby avoiding water leakage.
[0008] In one possible implementation, a float inlet valve is fixed on the side wall of the water tank, and the inlet end of the float inlet valve is connected to the inlet pipe. By setting the float inlet valve, when the cooling water level in the water tank drops to the lower limit position, the float inlet valve can be opened, and at this time the inlet pipe can automatically replenish water to the water tank to achieve the purpose of automatic water replenishment of the water tank.
[0009] In one possible implementation, a first drain pump is fixed to the bottom of the water tank, and the outlet of the first drain pump is connected to a first drain pipe. With the first drain pump, when the indoor unit is operating in heating mode, the first drain pump is in standby mode. Condensate is generated on the condenser in the outdoor unit, and the condensate drips into the water tank and is collected. When the condensate level in the water tank rises to a certain height, the first drain pump can start to extract the condensate from the water tank. Furthermore, when the indoor unit is operating in heating mode, the user needs to manually close the water valve on the inlet pipe connected to the float inlet valve to prevent the float inlet valve from continuously supplying water to the water tank. Additionally, the first drain pump is a float-type drain pump. When the condensate in the water tank rises to a certain height and triggers the float of the float-type drain pump, the first drain pump can automatically open and discharge the condensate. When the condensate level in the water tank drops to a certain height, the first drain pump can automatically close.
[0010] In one possible implementation, an electric heating wire is also fixed to the bottom of the water tank; when the evaporative air conditioner is used in a cold region and when the evaporative air conditioner is operating in defrost mode, the electric heating wire can automatically heat the water tank to prevent the water generated by defrosting on the condenser from freezing in the water tank, so that the defrost water in the water tank can be smoothly discharged through the first drain pump.
[0011] In one possible implementation, the indoor unit includes an indoor unit casing, an evaporator, and a fan; a second air inlet is provided on the rear side of the indoor unit casing, and a second air outlet is provided on the front side of the indoor unit casing. A nozzle is fixed at the second air outlet. The evaporator and the fan are fixed from back to front on the inner side of the indoor unit casing located between the second air inlet and the second air outlet; a filter is fixed at the second air inlet; through the filter, the filter can block dust in the air of the external environment from entering the interior of the indoor unit casing through the second air inlet, thereby effectively preventing dust accumulation on the evaporator and ensuring the heat exchange efficiency of the evaporator.
[0012] In one possible implementation, a cleaning component is connected to the rear side of the indoor unit casing. The cleaning component is used to clean the filter screen. By setting up the cleaning component, the cleaning component can clean the dust adsorbed on the filter screen, which has the advantage of convenient filter screen cleaning.
[0013] In one possible implementation, the cleaning assembly includes a support frame, a movable frame, and a cylinder. The support frame is fixed to the rear side of the indoor unit housing and corresponds to the second air inlet. The movable frame is movably connected to the rear side of the support frame via two vertically symmetrical guide rail assemblies. Several sets of brush bristles spaced from left to right are fixed to the front side of the movable frame, with the front ends of the brush bristles abutting against the filter screen. The cylinder is horizontally fixed to the rear side of the indoor unit housing, and the movable frame is fixed to the piston rod of the cylinder. The cylinder is used to drive the movable frame to move left and right so that the brush bristles clean the filter screen. By using this cleaning assembly, when the piston rod of the cylinder extends and retracts to drive the movable frame to move back and forth relative to the support frame, the several sets of brush bristles can clean the dust adsorbed on the filter screen, thus providing the advantage of convenient filter screen cleaning.
[0014] In one possible implementation, a drip tray is fixed to the bottom of the indoor unit casing, the evaporator is located above the drip tray, and a second drain pump is fixed to the bottom of the drip tray. The outlet of the second drain pump is connected to a second drain pipe. The drip tray collects condensate dripping from the evaporator, and the condensate is smoothly discharged outside the indoor unit casing by the second drain pump. The second drain pump is a float-type drain pump. When the condensate in the drip tray accumulates to a certain height and triggers the float of the drain pump, the second drain pump automatically starts and discharges the condensate. When the condensate in the drip tray drops to a certain height, the second drain pump automatically shuts off. Attached Figure Description
