Description
TECHNICAL FIELD
[0001] The utility model relates to an improvement of a curtain type air cooler, in particular to an improvement of the structure in the water tank of the air cooler. BACKGROUND
[0002] The air cooler mainly works on the physical principle of water evaporation and heat absorption. It is internally provided with a water tank, and the water in the water tank is delivered to a specially designed wet curtain by a water pump, so that the wet curtain is kept in a wet state. When the fan is running, air rapidly passes through the wet wet curtain, and the water evaporates in the process, absorbing heat in the surrounding air, thereby reducing the temperature of the blown air.
[0003] The air cooler mainly consists of a shell, a water tank, a water pump, a wet curtain and a fan. Generally, the water pump needs to be connected in the water tank, and the theme of the water pump is located in the shell. Once the water pump is damaged, the water in the water pump will enter the shell and leak, which may trigger an electric leakage accident. UTILITY MODEL CONTENTS
[0004] In order to overcome the deficiency that the water pump of the air cooler is not easy to maintain and is not safe, the utility model provides an air cooler convenient to use.
[0005] The technical scheme for solving the technical problem of the utility model is: an air cooler convenient to use, comprising a shell, a water tank, a wet curtain, a fan and a water pump for delivering water in the water tank to the wet curtain, the water tank being integrated on the shell and located at the lower part of the shell, and an enlarged part being arranged at the rear side of the bottom of the shell to increase the capacity of the water tank; the water pump is a submersible pump, and the submersible pump is located in the water tank and the water outlet pipe of the submersible pump is connected to the upper part of the wet curtain.
[0006] Further arrangement, the upper end of the wet curtain is a water distribution pipe, the water distribution pipe is horizontally arranged above the wet curtain, a plurality of water outlet holes are arranged on the water distribution pipe, and the submersible pump is connected to the water distribution pipe.
[0007] One option is that the submersible pump is connected to the side of the water distribution pipe through a hose.
[0008] Further, a water inlet nozzle is further arranged in the middle of the water distribution pipe, and the hose is connected to the water inlet nozzle.
[0009] In order to facilitate water to reach the wet curtain from below, a protective sleeve with an open lower end is further arranged above the water distribution pipe.
[0010] In order to facilitate observation of the water level, a liquid level pipe is arranged on the outer side of the water tank and connected to the water tank at the upper end and the lower end.
[0011] Further, a flow regulating valve is arranged on the hose.
[0012] In order to facilitate the traffic of the sky street, the knob of the flow regulating valve is arranged on the side of the shell.
[0013] In order to facilitate the replacement of the submersible pump, the submersible pump is fixed on the water tank through the fixing pieces on both sides of the submersible pump.
[0014] The utility model discloses a cold -air machine of prior art, which will not be described here.
[0015] The utility model discloses a beneficial effect lies in: 1, adopt submersible pump, waterway can be separated with circuit conveniently, thereby prevent the leakage phenomenon when waterway failure, very safe.2, when needing to maintain water pump, need not like external water pump and carry out complicated disassembly and connecting operation. Only need to empty a part in the water tank, can directly check, clean or replace spare part etc. maintenance work to the submersed pump, save maintenance time and cost.3, because submersible pump is wholly immersed in water, and water plays certain buffer and damping effect to it, and the vibration and noise generated when operating are absorbed and blocked by water, so that the cold -air machine is more quiet and stable in the operation process, and too much interference is not caused to the life, work or rest environment of user.
