Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning equipment, in particular to a device for recycling air-conditioning condensed water. Background Art

[0002] Most room air conditioners utilize a large temperature gradient and mechanical dew point for air supply. When the supply air temperature falls below the dew point corresponding to the mixing point of the fresh air and return air, condensation forms. This condensation falls under the influence of gravity onto the evaporator's drain pan and is discharged outdoors through a drain pipe. However, this method of dealing with condensation has many drawbacks: Because the condensation originates from the evaporator's surface, its temperature is low, and in environments with high moisture loads, the amount of condensation can be considerable, wasting energy by simply draining it away. In multi-story residential buildings without condensation piping, the condensation discharged by each household not only degrades the building's facade but can also easily lead to neighborhood conflicts. Failure to follow the installation instructions to ensure a certain slope during installation can result in an uneven condenser drain pan, leading to backflow of accumulated water. Due to the accumulation of insoluble particles such as dust in the air, air conditioners can easily accumulate debris during long-term operation, which can lead to severe blockage of the drain outlet and leakage. Summary of the Invention

[0003] In order to solve the above problems, the purpose of the present invention is to provide a device for recycling air-conditioning condensed water.

[0004] A device for recycling condensed water from an air conditioner, comprising a main control chip and a water leakage detection plate, a humidity sensor and an atomizing sheet respectively connected to the main control chip;

[0005] The water leakage detection board is arranged on the finned evaporator of the air conditioner indoor unit, and is used to detect whether condensed water flows through and send the detection information to the main control chip;

[0006] The humidity sensor is used to detect the current ambient humidity and send the detection information to the main control chip;

[0007] One or more atomizing sheets are arranged on the finned evaporator of the indoor unit of the air conditioner, and the atomizing sheets atomize the condensed water when working;

[0008] The main control chip is used to control the atomizing plate to open or close according to the detection information of the water leakage detection board and the detection information of the humidity sensor.

[0009] Preferably, the water leakage detection board includes two copper-clad areas isolated from each other, and the two copper-clad areas are connected in series with the circuit of the main control chip. When condensed water flows down and covers between the two copper-clad areas, the two copper-clad areas are turned on, and the main control chip receives the water leakage detection board connection signal; otherwise, the water leakage detection board is disconnected from the main control chip.

[0010] Preferably, the main control chip is used to control the atomizing plate to start working when it receives a water leakage detection board connection signal and the humidity value is within a preset atomization range.

[0011] Preferably, the two copper-clad areas are separated by a groove on the water leakage detection board.

[0012] Preferably, the water mist of the atomizing plate is discharged in a direction toward the heat dissipating fins of the fin evaporator, and / or the water mist of the atomizing plate is discharged in a direction toward the room.

[0013] Preferably, the atomizing sheet is an ultrasonic atomizing sheet.

[0014] Because this utility model adopts the above-mentioned solution, there is no need for a drain pipe or water tray to collect condensed water. By combining a leak detection plate with a humidity sensor, the controller directly controls the atomizing blades to atomize the condensed water after detecting that the condensed water meets the atomization conditions. Furthermore, since the condensed water temperature is low, spraying the atomized condensed water onto the fins effectively cools the room. Furthermore, the atomized condensed water can also be sprayed indoors to serve as a humidifier. Furthermore, the large number of fine water droplets released during the atomization process adsorb and combine with smoke, dust, and other particles floating in the air, causing them to settle and purify the air.

[0020] The embodiments of the present utility model are described in detail below.

[0021] like Figure 1 and Figure 2 As shown, this embodiment provides a device for recycling air-conditioning condensate water, including a main control chip 2 and a water leakage detection board 3, a humidity sensor 5, and an atomizing sheet 4 respectively connected to the main control chip 2. The main control chip 2 can be directly used as the controller of the air conditioner or a separate controller.

[0022] The water leakage detection board 3 is mounted on the finned evaporator 1 of the air conditioner indoor unit and is used to detect whether condensed water is flowing through the evaporator and transmit the detection information to the main control chip 2. The water leakage detection board 3 is configured as a switch connected in series to the connection circuit of the main control chip 2. When condensed water is detected, the switch is turned on; otherwise, the switch is turned off.

[0023] like Figure 3 As shown, the water leakage detection board 3 in this embodiment includes a first copper-clad area 31 and a second copper-clad area 32 that are isolated from each other. The two copper-clad areas are connected in series to the circuit with the main control chip 2. Therefore, in a dry state, since the two copper-clad areas are separated from each other, the circuit is disconnected. When condensed water flows down and covers between the two copper-clad areas, due to the conductivity of water, the two copper-clad areas are turned on. At this time, the circuit is turned on, and the main control chip 2 can determine whether there is condensed water flowing on the water leakage detection board 3 based on the change in the on-off state of the circuit. Furthermore, the two copper-clad areas are separated by a groove 33 on the water leakage detection board 3. On the one hand, the groove 33 is easy to process, and on the other hand, the groove 33 can play a certain guiding role for the condensed water flowing through. In this application, a water leakage detection board 3 is provided to detect whether condensed water has condensed on the air conditioner heat exchanger, and is used to cooperate with the humidity sensor 5 to control whether the atomizing plate 4 is working. Optionally, as Figure 3 As shown, a water leakage detection plate 3 is positioned below the finned evaporator 1. After condensation forms on the evaporator surface, it slides downward under the influence of gravity and flows across the surface of the water leakage detection plate 3, enabling timely detection of the presence of condensation on the evaporator surface. In this embodiment, when condensation flows down and covers the space between the two copper-clad areas, the two copper-clad areas become conductive, and the main control chip 2 receives a signal indicating that the water leakage detection plate 3 is on.

[0024] The humidity sensor 5 is used to detect the current ambient humidity and send the detection information to the main control chip 2. The capacitance value of the humidity sensor 5 will change under different humidity conditions. The main control chip 2 captures the change in the capacitance value of the humidity sensor 5, converts and analyzes it, and then derives the humidity value. When the humidity value is within the range that can be atomized, the main control chip 2 outputs an output to control the atomizing plate 4 to operate.

[0025] The atomizing sheet 4 is used to atomize the condensed water. In the embodiment, the atomizing sheet 4 is an ultrasonic atomizing sheet 4. One or more atomizing sheets 4 are arranged on the evaporator of the indoor unit of the air conditioner. When the atomizing sheet 4 is working, it atomizes the condensed water passing through into water mist.

[0026] The main control chip 2 is used to control the atomizer 4 to turn on or off based on the detection information from the water leak detection board 3 and the detection information from the humidity sensor 5. Specifically, when the main control chip 2 receives the power-on signal from the water leak detection board 3 and the humidity value detected by the humidity sensor 5 is within the preset atomization range, the main control chip 2 controls the atomizer 4 to start operating and atomize the condensed water. In this embodiment, the main control chip 2 uses a single-chip microcomputer.

[0027] Depending on the intended use of the atomized condensed water, the mist from the atomizing blade 4 can be directed toward the heat dissipating fins of the finned evaporator 1 and / or toward the interior of the room. Because the condensed water is cold, spraying the atomized condensed water onto the fins effectively cools the room. Alternatively, the atomized condensed water can be sprayed indoors to serve as a humidifier. Furthermore, the large number of tiny water droplets released during the atomization process attract and bind to airborne smoke, dust, and other particles, causing them to settle and purify the air.

[0028] In the above embodiment, the drainage pipe is reduced and a water leakage detection plate 3, a humidity sensor 5 and an atomizing plate 4 are added to the indoor and outdoor units of the air conditioner. The condensed water generated on the evaporator is atomized into water vapor through the ultrasonic atomizing plate 4 and blown into the room to humidify and purify the air, or sprayed onto the fins to absorb heat and cool down, thereby making full use of the condensed water on the evaporator of the air conditioner.

[0029] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
