Air conditioner condensate water overflow control and alarm device

Abstract

The utility model relates to the technical field of air-conditioning refrigeration, and particularly discloses an air-conditioning condensate water overflow control and alarm device which comprises a water pan used for collecting condensate water, an electric two-way valve used for controlling water flow and a temperature controller used for turning on an air conditioner, and a float switch is arranged on the inner bottom wall of the water pan through a support. And the water level sensors are connected with the overflow controller through control lines to monitor the water level of the condensate water in real time. When the water level is not abnormal, the floating ball switch is in a normally-open state, the overflow controller opens the electric two-way valve, and the air conditioner operates normally; if drainage is not smooth, the water level of the water pan rises, and the floating ball rises accordingly, when the water level reaches the limit, the float switch is closed, the overflow controller closes the electric two-way valve, the air conditioner stops running, meanwhile, the buzzing alarm is started to remind a user to stop running of the air conditioner, and therefore the consequence that condensate water overflows to bubble the top is prevented.

Description

Technical Field

[0001] The utility model belongs to the technical field of air conditioning and refrigeration, and in particular relates to an air conditioning condensation water overflow control and alarm device. Background Art

[0002] During the operation of the air conditioner, since the surface temperature of the evaporator is lower than the dew point temperature of the air, condensation water is easily generated on the surface of the evaporator and the outer surface of the condensation water pipe. This is a common physical phenomenon in air-conditioning systems, especially in an environment with high humidity.

[0003] However, the existing condensate water pipe construction is unreasonable, such as insufficient slope, too small pipe diameter, and failure to set a suitable drainage slope, which may lead to poor condensate discharge and then cause condensate overflow. After the air-conditioning system has been running for a long time, dust, bacteria and other impurities may accumulate in the condensate water pipe, causing pipe blockage and affecting the normal discharge of condensate. The problem of air-conditioning condensate easily overflowing in the water receiving tray can easily cause bubble ceiling and cause indoor ceiling mold and discoloration, so it is urgently needed to improve it. Utility Model Content

[0004] The utility model aims to provide an air-conditioning condensate water overflow control and alarm device to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An air conditioning condensate overflow control and alarm device, comprising:

[0007] Drain tray;

[0008] A waterproof double-sided tape is attached to one side of the inner bottom wall of the water receiving tray, a mounting bracket is attached to one side of the top of the waterproof double-sided tape, and a non-magnetic suction tube is fixedly connected to the middle of one side of the top of the mounting bracket;

[0009] A reed switch is fixedly connected to the middle of the bottom of the non-magnetic suction tube, a floating ball is sleeved on one side of the surface of the reed switch, and the top of the floating ball overlaps the bottom of the non-magnetic suction tube.

[0010] Preferably, one side of the top of the non-magnetic suction tube is electrically connected to a first control line, one end of the first control line is electrically connected to an overflow controller, one side of the surface of the overflow controller is electrically connected to a second control line, and the front end of the second control line is electrically connected to an air conditioning thermostat.

[0011] Preferably, one side of the top of the water receiving pan is fixedly connected to the indoor unit of the air conditioner, and one side of the back side of the overflow controller is fixedly connected to one side of the indoor unit of the air conditioner.

[0012] Preferably, a return pipe is fixedly connected to the top of one side of the air conditioner indoor unit, an electric two-way valve is fixedly connected to one side of the return pipe surface, a third control line is electrically connected to one side of the electric two-way valve surface, and the front end of the third control line is electrically connected to the surface of the overflow controller.

[0013] Preferably, a water supply pipe is fixedly connected to the bottom of one side of the indoor unit of the air conditioner, and the water supply pipe is arranged in parallel with the water return pipe.

[0014] Preferably, a drain pipe is fixedly connected to the middle portion of one side of the water receiving tray.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] (1) The float switch composed of a non-magnetic suction tube, a reed switch and a float ball is fixed to the inner bottom wall of the water receiving tray by waterproof double-sided tape, which solves the problem that the float switch is difficult to install on the water receiving tray conveniently and is extremely easy to operate.

[0017] (2) When the water level is normal, the overflow controller supplies power through the third control line to open the electric two-way valve, allowing the air conditioner to operate in cooling mode. When the water level reaches 2 to 2.5 cm, the float presses against the non-magnetic suction tube, causing the non-magnetic suction tube to transmit information to the overflow controller through the first control line. The float switch composed of the non-magnetic suction tube, the reed switch and the float stops supplying power to the electric two-way valve at the front end of the third control line, causing the electric two-way valve to close and the air conditioner to stop cooling. At the same time, the overflow controller starts the buzzer alarm, making it easy to remind the staff to turn off the air conditioner thermostat. The overflow controller is closed through the air conditioner thermostat, thereby achieving the effect of preventing the air conditioner condensate from overflowing and alarming, and is convenient for the staff to operate.
