Abstract
The invention provides a water dispenser capable of solving the problem in prior art that drinking water is repeatedly heated in a hot liner. When the water dispenser is power on, the drinking water is heated with a first power; when the drinking water is boiled, the drinking water keeps warm with a second power; and when high-temperature boiling water is needed, the drinking water is heated with the maximum power, and thus, the drinking water is free of repeatedly heating.
Description
Technical field
The present invention relates to electricity field, particularly a kind of energy-saving drinking machine.
Background technology
Water dispenser has been widely used in family and office building, but drinking water in hot courage after heating repeatedly, can form " thousand boiling water ", this water contains the harmful substances such as heavy metal, arsenide, for a long time drink can the harm gastrointestinal health.
Summary of the invention
The present invention proposes a kind of water dispenser, has solved drinking water problem through repeatedly heating in hot courage in the prior art.
Technical scheme of the present invention is achieved in that
A kind of water dispenser comprises: be arranged on the on ﹠ off switch of casing front, the control plugged; The Fast Heating key, control is with peak power heating drinking water; The electrothermal tube that is used for the heating drinking water; Single-chip microcomputer is connected to described on ﹠ off switch and described Fast Heating key, controls the pulse width of output pulse signal according to user's order; Wave filter, the pulse signal that described single-chip microcomputer is exported is filtered into direct current signal; The N-type mosfet transistor, its grid is connected to the output of described wave filter, and its drain electrode is connected to described electrothermal tube, and its source electrode is connected to earth potential; Temperature sensor, the temperature signal of output of drinking water; Analog-digital converter is converted to digital form with the temperature signal of analog form, sends to the input port of described single-chip microcomputer.
Alternatively, described wave filter is the LC wave filter.
Alternatively, described single-chip microcomputer is 51 single-chip microcomputers.
The invention has the beneficial effects as follows: during start, with the first power heating, boiled after, with the second power insulation, when needing high warm water, with the peak power heating, drinking water need not repeatedly to heat.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the control block diagram of a kind of water dispenser of the present invention.
The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
As shown in Figure 1, a kind of water dispenser of the present invention comprises: be arranged on the on ﹠ off switch 10 of casing front, and plugged after the control start, with the first power heating drinking water, for example the first power is 60% of rated power; The Fast Heating key, when the user needed high warm water, control was with peak power heating drinking water, and for example peak power can be rated power; The electrothermal tube 60 that is used for the heating drinking water; Single-chip microcomputer 30, input port are connected on ﹠ off switch 10 and Fast Heating key 20, control the pulse width of output pulse signal according to user's order; Wave filter 40, the pulse signal that single-chip microcomputer 30 is exported is filtered into direct current signal; N-type mosfet transistor 50, its grid is connected to the output of wave filter 40, and its drain electrode is connected to electrothermal tube 60, and its source electrode is connected to earth potential; Temperature sensor 70, the temperature signal of output of drinking water; Analog-digital converter 80 is converted to digital form with the temperature signal of analog form, sends to the input port of single-chip microcomputer 30.
For example, when the user opened on ﹠ off switch 10, the pulse signal that single-chip microcomputer 30 output is corresponding with the first power, wave filter 40 were filtered into direct current signal with pulse signal, control N-type mosfet transistor 50 and are operated in the variable resistor district, and electrothermal tube is with the first power work; Drinking water reaches sets boiled temperature, and the temperature signal that single-chip microcomputer is exported according to temperature sensor 70 reduces the width of pulse signal, increases the resistance of N-type mosfet transistor 50, and electrothermal tube is incubated with the second power; When the user thinks to obtain high warm water fast, the pulse signal of single-chip microcomputer 30 output maximum pulse, the 50 complete conductings of N-type mosfet transistor, electrothermal tube heats with rated power.
Preferably, wave filter 40 is the LC wave filter, and single-chip microcomputer 30 is 51 single-chip microcomputers.
The invention has the beneficial effects as follows: during start, with the first power heating, boiled after, with the second power insulation, when needing high warm water, with the peak power heating, drinking water need not repeatedly to heat.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
