Abstract
The utility model relates to a fuzzy control type electric heat shower, which is composed of a water chamber and a control circuit, wherein, the control circuit is composed of a power circuit, a reset circuit, a central control circuit (CPU), an output display circuit, a control operating mechanism circuit, and a pre-setting circuit. An input end of the central control circuit (CPU) is connected with an output signal line of a hot water quantity sensor, the output display circuit comprises a hot water quantity display part, the sensor is vertically installed in the water chamber, more than one independent temperature sensing element are arranged in an outer shell of the sensor at intervals, and intervals of the temperature sensing elements are determined by volume of equal dividing water chambers. The utility model has the advantages of simple structure, and convenient use. The utility model can duly display the hot water quantity in the water chamber in order to bring convenience to users.
Description
The utility model relates to a kind of electric shower-bath, especially a kind of top ability of swimming electric shower-bath that adopts fuzzy control.
Along with the raising of people's living standard, increasing people purchases at home and uses various instant shower heaters.Electric shower-bath is easy to install and use, economical and practical and used widely.Because top ability of swimming electric shower-bath is supplementing water relatively constantly in use, the hot water amount who provides is big, and technology is comparatively advanced at present.But, owing to always hold in the water courage of top ability of swimming electric shower-bath and expired water, cold water inlet is located at the bottom of water courage, and to reach the hot water that presets temperature be that delivery port from water courage top flows out downwards, therefore there is not hot water amount's demonstration, so in use, can't learn whether also have hot water to use, to bring inconvenience to use.
The purpose of this utility model is to provide a kind of fuzzy control electric shower-bath, and it can measure the hot water amount in the ability of swimming electric shower-bath water courage of top, and shows the hot water amount in the water courage on the electric shower-bath exterior display device, uses with convenient.
The purpose of this utility model is achieved in that a kind of fuzzy control electric shower-bath, it is by the water courage, power circuit, reset circuit, central control circuit (CPU) and the control circuit composition of exporting display circuit, controlling actuating mechanism circuit and pre-set the circuit formation, the input termination hot water amount signal of sensor line of wherein said CPU, described display circuit comprises the hot water amount display part, and sensor is vertically mounted in the water courage.
Be interval with more than one independently temperature-sensing element in the described outer sensor housing.
Decide with the volume of five equilibrium water courage at the interval of described temperature-sensing element.
The utility model is simple and reasonable, and is easy to use, can show the hot water amount in the water courage in time, thereby brought facility for the user.
Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail.
Fig. 1 is a water container structure schematic diagram of the present utility model.
Fig. 2 is a control circuit schematic diagram of the present utility model.
Fig. 3 is that liquid crystal indicator of the present utility model is arranged schematic diagram.
Fig. 4 is a control flow chart of the present utility model.
Referring to Fig. 1-4, the utility model is a top ability of swimming electric shower-bath, and the inside of its water courage 1 has been full of water.One side bottom of water courage 1 is established water inlet 2, and opposite side sets out water pipe 3, and hot water flows out from the top of outlet pipe 3.Vertically plug sensor 4 in the water courage 1.Independently temperature element 5 of an above space is set in the sensor 4, and the spacing of temperature element 5 is provided with the setting that is shaped as according to water courage 1, thereby can record the hot water amount of different water levels in the water courage 1.The hot water amount here be meant the temperature that can blend 40 ℃ warm water how much be called the hot water amount.Sensor 4 is provided with 5 temperature elements 5 in the present embodiment, and with the volume five equilibrium of water courage 1, the hot water amount's of sensor representative weighting should equate that the warm water that each sensor is surveyed is represented the water of 1/5 volume.The hot water that calculates in the present water courage according to the constant law of heat can go out the warm water that how much reaches design temperature.All holding wires 6 of temperature element 5 are connected to the input of the CPU (CPU) of control circuit 7, and survey water courage 1 hot water amount's signal is reached CPU.
Referring to Fig. 2,3, control circuit of the present utility model is by power circuit, reset circuit, central control circuit and export display circuit, control actuating mechanism circuit and pre-set circuit and constitute.Get the P0.3 of electric leakage signal at power end to CPU.CPUP2.5 mouth line meets output relay control heating executing agency; the P3.0 of CPU connects the leakage protection circuit part; when wherein P3.0 is high level, the N2 conducting, power circuit is conducting over the ground; mutual inductor will have signal to pass through the output of circuit mutual inductance detection comparison circuit; D will export high level signal, enter P0.3, whenever power on once; the CPU self check once is used for verifying whether the detection of electrical leakage system is normal.The P1.6 of CPU is used for detecting supply voltage, and the P3.1 of CPU can be the reserved opening line.
The mouth line P1.0-P1.5 of CPU connects the output signal line of sensor 5, and the P3.2 of CPU, P3.3, P0.0, P0.1, P0.2 connect external key circuit is set, the termination reset circuit that resets of CPU.The P3.4-P3.7 of CPU and P5.0-P5.1 connect memory chip and clock chip, and wherein clock chip is connected to stand-by power supply.The mouth line of CPU also is connected to power supply indication, indicating fault and warning indication etc.The P5.2-P5.7 of CPU, P6.0-P6.7, P4.0-P4.5 connect large LCD and show.Show the demonstration that comprises hot water amount in date, time, temperature and the water courage 1.Data that CPU sends here according to sensor 5 and the data that pre-set that circuit is set through key scanning, enter the temperature state of a control, carry out processing such as fault detect again.Show hot water amount in the water outlet courage 1 on screen, the lattice of hot water amount's demonstration such as mobile phone remaining power amount shows in the water courage 1, and is comparatively directly perceived, makes things convenient for the user.Therefore the user in use can be according to hot water amount's the reasonable arrangement and use of the demonstration time.
