An object of the utility model is to provide a dehumidifier according to water level control switch can prevent effectively that the water storage device waste water of dehumidifier from spilling over, and is safer during the use.
The above technical purpose of the utility model is realized through following technical scheme:
a dehumidifier controlling a switch according to a water level comprises a water storage device and a unit control circuit, wherein the unit control circuit comprises a fan control circuit and a compressor control circuit which are respectively connected with a fan and a compressor in series, the dehumidifier also comprises an anti-overflow shutdown circuit, the anti-overflow shutdown circuit comprises a power supply, a relay KA1 and a first water level detection device for detecting the water level of the water storage device, an internal circuit of the first water level detection device is closed after the water level of the water storage device is over-full, and the anti-overflow shutdown circuit is electrified; the fan control circuit comprises a contactor KM1, and the compressor control circuit comprises a contactor KM2; the relay KA1 comprises a normally closed contact KA1-1 connected in series with the coil of the contactor KM1, and the contactor KM1 comprises a normally closed contact KM1-2 connected in series with the coil of the contactor KM 2.
Therefore, in the unit control circuit, the fan control circuit is connected with the compressor control circuit in parallel and is powered by a 220V alternating current power supply. The dehumidifier mainly removes water by the operation of the fan and the compressor, so that when the water level in the water storage device is over full, the fan and the compressor need to be shut down to prevent the wastewater from overflowing. If the fan control circuit and the compressor control circuit are disconnected respectively, the fan and the compressor can be shut down without being electrified. Based on the principle, in the scheme, the fan control circuit and the compressor control circuit are switched on and off through the anti-overflow shutdown circuit.
Concretely, anti-overflow shutdown circuit contains the power, relay KA1 and the water level detection device one that is used for detecting water storage device water level. When the water level in the water storage device does not reach the triggering condition of the first water level detection device, an internal circuit of the first water level detection device is in a disconnected state, and the anti-overflow shutdown circuit is not electrified; when the water level in the water storage device is too high and reaches a trigger condition of a first water level detection device, an internal circuit of the first water level detection device is closed, an anti-overflow shutdown circuit is electrified, a coil of a relay KA1 is electrified, the relay KA1 is connected in series in a fan control circuit, an originally closed normally closed contact KA1-1 is disconnected after the coil of the relay KA1 is electrified, the fan control circuit is further disconnected, the power is not electrified, and the fan is shut down; when the fan control circuit is disconnected and not powered on, the contactor KM1 in the fan control circuit is connected in series in the compressor control circuit because the coil is not powered on, the normally closed contact KM1-2 which is originally closed is disconnected, the compressor control circuit is further disconnected, the coil of the contactor KM2 is not powered on, the power supply for the compressor cannot be continued, and the compressor stops operating. In the scheme, when the water storage device of the compressor is full of water, the fan is firstly turned off through the first water level control device, and then the compressor control circuit is interlocked through the fan control circuit, so that the function of simultaneously turning off the compressor is achieved, and after the fan and the compressor are turned off, the dehumidifier cannot continuously remove water, so that the wastewater in the water storage device is prevented from overflowing. The first water level detector may be a commercially available float level switch, electrode type level switch, or the like.

Therefore, before the waste water in the water storage device overflows, if the waste water reaches half volume of the water storage device, the water level early warning circuit prompts staff that the waste water in the water storage device is full in advance, and the staff can avoid automatically shutting down the fan and the compressor in the later period of the dehumidifier after toppling over in advance to influence the dehumidification effect. The water level early warning circuit is different from an anti-overflow shutdown circuit, only plays a role in early warning and prompting, and cannot shut down the dehumidifier.
Specifically, the unit control circuit comprises an early warning circuit connected with the fan control circuit in parallel, and the early warning circuit comprises a second warning device. The water level early warning circuit contains the power, relay KA2 and water level detection device two, when the waste water level in the water storage device reaches the detection range of water level detection device two, if the waste water volume is the volumetric half of water storage device, two internal circuits of water level detection device are closed, relay KA2 circular telegram, relay KA2 establishes ties in the early warning circuit, the normally open contact KA2-1 of disconnection originally is closed, the closed circular telegram of early warning circuit, warning device two sends warning signal in order to remind the staff to pour water.
As the utility model discloses a preferred, water level early warning circuit contains circuit switch.
Therefore, after the circuit switch is arranged in the water level early warning circuit, a worker can select whether to start the early warning function according to actual needs, and when the early warning function is required, the circuit switch is closed, the water level early warning circuit can be closed to work, and the warning device II can warn; if the circuit switch is turned off, no warning is given.
As the utility model discloses a preferred, water level detection device one with water level detection device two is capacitanc water level switch.
Therefore, compared with other water level detectors, the capacitive water level switch has the advantages of being small and exquisite, convenient to install, corrosion-resistant and the like.
The water storage device preferably comprises a plurality of clamping pieces which are respectively arranged at different height positions of the water storage device, and each clamping piece comprises a clamping groove; the first water level detection device and the second water level detection device are detachably clamped in the clamping grooves respectively.
Thus, the capacitive water level switch is a non-contact water level switch, is not directly installed inside the container, and is generally fixed to the outer wall of the container by adhesion. If the capacitive water level switch is bonded on the outer wall of the water storage device, when waste water in the water storage device is dumped, the capacitive water level switch is pulled easily, so that the capacitive water level switch is torn off or damaged, and the capacitive water level switch is not easy to install again in the later period and also easily damages an internal electric wire. For solving above problem, in the present case, contain a plurality of joint spares of installing at the different altitude position of water storage device, joint spare contains the draw-in groove, and water level detection device one is capacitanc water level switch detachable joint in the draw-in groove promptly with water level detection device two, when needing to empty waste water, with each capacitanc water level switch from the draw-in groove that corresponds take out can, can not tear capacitanc water level switch and simple to operate.
As the utility model discloses a preferred, warning device one contains bee calling organ.
Therefore, after the fan and the compressor are shut down, the general warning device has a limited warning effect like an indicator lamp, and in the case, the warning device further comprises a buzzer, so that the buzzer can more effectively prompt a worker that the water storage device needs to be poured when the water is full.
