Abstract
The utility model discloses a circuit for dehumidifier detects for the signal output part who detects the water -level switch of dehumidifier water tank water level state connects main control chip's signal input pin, water -level switch's output and main control chip's signal input pin between the circuit connection power end. The utility model discloses circuit structure provides detection efficiency, does not need to install the frock water tank before getting into operation measuring room again, and the measuring need not retake out the frock water tank after accomplishing, uses manpower sparingly, need not to use the frock water tank, can not take place the dirty circumstances of transferring to the product yet.
Description
Technical field
The utility model relates to dehumidifier field, relates in particular to the testing circuit in dehumidifier manufacturing process.
Background technology
Dehumidifier is in order to improve human lives's comfortableness, maintain indoor environment humidity in specified scope onePlant device. Traditional dehumidifier possesses dehumidifying (refrigeration) system, and drip tray and water tank, in water tank assembling positionPut, a microswitch packing into and the full state of water with induction water tank has been installed. In its electric control function design, increaseAdd P2 defencive function, when dehumidifier is not installing under the state that in water tank or water tank, water is full, dehumidifierCan not move.
In dehumidifier procedure for producing, complete machine need to move detection, due to the existence of P2 defencive function, mustMust install a frock water tank that is specifically designed to test. When production testing, enter operation at streamline and detectThe frock water tank of taking before room, installs to frock water tank on complete machine, and operation is taken out frock water after detecting room againCase. Because frock water tank all recycles, cleannes be difficult to keep, use process in often by dirtyDirt is transferred on the product of producing, and has quality risk. In addition, operation detects use frock water tank in roomBe assembled on complete machine, need at least 30 frock water tank turnovers to use, the frock water that every money product needed is specialCase, needs 2 people to operate altogether. In process of production, affect greatly the production efficiency of product, becomeFor bottleneck operation.
Utility model content
Technical problem to be solved in the utility model is to realize one not need assembly tooling water tank to dehumidifyThe circuit structure that machine operation detects.
To achieve these goals, the technical solution adopted in the utility model is: the electricity detecting for dehumidifierRoad, connects the letter of main control chip for detection of the signal output part of the water level switch of water tank for dehumidification machine water position statusNumber input pin, the circuit between the signal input pin of the output of described water level switch and main control chipConnect power end.
Described dehumidifier is provided with the button of controlling described power end power supply state.
The output of described water level switch connects the signal input pin of main control chip, described electricity through resistance R 2Source is connected between resistance R 2 and the output of water level switch through resistance R 1.
The utility model circuit structure provides detection efficiency, before entering operation detection room, does not need to install againFrock water tank, does not need to take out frock water tank again after having detected, save manpower, without using frock water, can there is not the dirty situation of transferring to product in case yet.
Brief description of the drawings
Below the mark in content and figure that in the utility model description, every width accompanying drawing is expressed is briefly described:
Fig. 1 is the circuit structure diagram detecting for dehumidifier;
Mark in above-mentioned figure is: 1, main control chip; 2, water level switch.
Detailed description of the invention
Dehumidifier is provided with main control chip 1, for detection of the signal of the water level switch 2 of water tank for dehumidification machine water position statusOutput connects the signal input pin of main control chip 1, and as shown in Figure 1, the utility model is at water level switch 2Output and the signal input pin of main control chip 1 between circuit be connected power end (5V), utilize power supplyThe signal of water level switch 2 is fallen in end shield, and in order to control the shielding time, dehumidifier is provided with control power endThe button of power supply state, can, in the time detecting, shield the signal of water level switch 2 by button, reach detectionThe object of main control chip 1 working procedure, and after detection, do not affect the normal use of dehumidifier. By increasingKey-press input specific instruction, by the function of P2 guard shield, is examined mould by this functional specification in manufacturing works simultaneously soonIn formula, prevent that terminal user maloperation from forming P2 shielding.
For guaranteeing the job stability of water level switch 2, the output of water level switch 2 is through resistance R 2 (2K Ω)Connect the signal input pin of main control chip 1, and resistance R 2 (2K Ω) and main control chip 1 signal inputBetween pin, through capacity earth, power end is connected to the output of resistance R 2 and water level switch 2 through resistance R 1Between, ensure testing circuit working stability.
By reference to the accompanying drawings the present invention is exemplarily described above, obviously the utility model specific implementation is notBe subject to the restriction of aforesaid way, as long as the various non-reality that has adopted method design of the present invention and technical scheme to carry outThe improvement of matter, or without improving, design of the present invention and technical scheme are directly applied to other occasion,All within protection domain of the present utility model.
