Abstract
The utility model provides a warm air heating control circuit of a body cleaner, which comprises a main control chip and a warm air blower power supply circuit composed of a warm air blower and a warm air blower power supply interface, wherein the warm air blower power supply circuit is connected with a warm air blower current sampling unit; the output end of the warm air blower current sampling unit is connected with the input end of the main control chip. According to the warm air heating control circuit of the body cleaner, the warm air blower current sampling unit is arranged, when the warm air blower current sampling unit detects that the current of the warm air blower is abnormal, the main control chip disconnects the power supply of a warm air heating wire and the warm air blower, prevents the superheating damage of the warm air heating wire and the self rotation blocking damage of the warm air blower, and meanwhile avoids the situation that a user is burnt or a fire disaster is caused.
Description
Technical field
The utility model relates to sanitary equipment technical field, specifically a kind of sanitary equipment warm braw heating control circuit.
Background technology
Warm air function is the prerequisite basic function of sanitary equipment in the market.When user selects warm air function, computer control panel is controlled warm braw blower fan, warm braw heater strip energising work.Warm braw heater strip is 220V heater element, and computer control panel makes its heating by controlling the power of warm braw heater strip, sends heat energy, and the wind blowing out by warm braw blower fan, sends sanitary equipment engine body exterior, and Human body washing buttocks is later dried.
Warm braw blower fan is when sending warm braw; warm braw heater strip is also played to the effect of cooling protection; and occur stall or damage while cannot work when warm braw blower fan, warm braw heater strip can cause periphery working of plastics and the damage of self because instantaneous temperature is too high, even scalds human body or causes fire.
In order to stop the generation of this type of phenomenon, avoid the damage of periphery working of plastics and warm braw heater strip self, reduce the possibility that human body scald, fire occur, be necessary to design a kind of warm braw heating control circuit, by this circuit, detect the running status of warm braw blower fan, avoid warm braw heater strip to cross cause thermal damage and the damage of warm braw blower fan stall.
Utility model content
The purpose of this utility model is to provide a kind of running status that can detect warm braw blower fan, avoid warm braw heater strip to cross the sanitary equipment warm braw heating control circuit that cause thermal damage and warm braw blower fan stall damage.
The technical solution of the utility model is:
A kind of sanitary equipment warm braw heating control circuit, comprise main control chip, the warm braw blower fan current supply circuit being formed by warm braw blower fan and warm braw blower fan power supply interface, described warm braw blower fan current supply circuit is connected with warm braw blower fan current sampling unit, and the output of described warm braw blower fan current sampling unit is connected with the input of main control chip.
Described sanitary equipment warm braw heating control circuit, described warm braw blower fan current sampling unit comprises sampling resistor and voltage sample interface, described sampling resistor is connected on warm braw blower fan current supply circuit, the two ends of described sampling resistor are parallel with voltage sample interface, and the output of described voltage sample interface is connected with the input of main control chip.
The utility model is by arranging warm braw blower fan current sampling unit, when warm braw blower fan current sampling unit detects the current anomaly of warm braw blower fan, main control chip cuts off the power supply of warm braw heater strip and warm braw blower fan, avoid warm braw heater strip to cross cause thermal damage and warm braw blower fan self stall and damage, user or cause that the situation of fire occurs has also avoided burning simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of sanitary equipment warm braw heating control circuit, comprise main control chip 1, warm braw blower fan current supply circuit, warm braw heater strip current supply circuit, warm braw blower fan current supply circuit comprises warm braw blower fan 3 and warm braw blower fan power supply interface 2, warm braw heater strip current supply circuit comprises warm braw heater strip 5 and warm braw heater strip power supply interface 4, the signal output part of main control chip 1 is connected with the signal input part of warm braw heater strip power supply interface 4 with warm braw blower fan power supply interface 2 respectively, on warm braw blower fan current supply circuit, be connected with sampling resistor 6, sampling resistor 6 is connected with warm braw blower fan 3, sampling resistor 6 two ends are parallel with voltage sample interface 7, the signal output part of voltage sample interface 7 is connected with the signal input part of main control chip 1.
Operation principle of the present utility model:
When warm air function starts, the voltage at sampling resistor 6 two ends that main control chip 1 is come according to voltage sample interface 7 feedbacks, judges that whether the electric current of warm braw blower fan 3 is normal.During the 3 normal work of warm braw blower fan, electric current is certain, and (such as 12V, 0.45A) is set as A1; And when the 3 appearance damages of warm braw blower fan, the warm braw blower fan electric current that main control chip 1 detects is 0; When stall appears in warm braw blower fan 3, it is a lot of that the electric current of warm braw blower fan 3 exceeds normal current, or even multiple relation, and setting critical value is A2.
When main control chip 1 detection warm braw blower fan 3 electric currents are A1, illustrate that warm braw blower fan 3 is working properly, main control chip 1 is controlled warm braw heater strip power supply interface 4 and is connected, and heats to 5 energisings of warm braw heater strip; When main control chip 1 detects warm braw blower fan 3 electric currents, be that 0(warm braw blower fan 3 opens circuit), or when electric current is greater than critical value A2, illustrate that 3 work of warm braw blower fan are undesired, now, main control chip 1 is controlled warm braw heater strip power supply interface 4, warm braw blower fan power supply interface 2 disconnects, cut off the power supply of warm braw heater strip 5 and warm braw blower fan 3, thereby avoid the mistake cause thermal damage of warm braw heater strip 5 and the stall of warm braw blower fan 3 to damage.
The above embodiment is only that preferred embodiment of the present utility model is described; not the novel scope of this use is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection domain of claims of the present utility model.
