Abstract
The utility model relates to a constant-temperature water box, belonging to the electric apparatus technical field, comprising a water box body, a heating tube in the water box and a temperature sensor, characterized in that: a PID intelligent meter is fixed at the outer side of the water box body and the temperature sensor is electrically connected with the PID intelligent meter; the PID intelligent meter is electrically connected with the heating tube by a solid relay. Because of the precise control of the PID intelligent meter, the control precision of the constant-temperature water box is increased and the power supply is saved. The switch on and switch off of the heating circuit is controlled by the solid relay and compared with the general switch, the solid relay has advantages of long service life, high sensitivity, quick switch and small electromagnetic interference. At the same time, an audible and visual alarm is added and when the water is lack, the audible and visual alarm hints that the water level reaches the safe water level; when the water is lack, the heating is stopped to prevent dry burning and damage the heating tube.
Description
Technical field
The utility model relates to appliance field, particularly relates to a kind of constant temperature water tank.
Background technology
The function of constant temperature water tank is that water stores after heating source is heated to uniform temperature, when naturally cooling to this temperature when following, and heating automatically.But existing constant temperature water tank is low because of temperature control precision, exists and takes electricity and hidden danger, also occurs the dry combustion method phenomenon sometimes.
Summary of the invention
At the defective in the above-mentioned field, the invention provides a kind of constant temperature water tank, can accurately control steady temperature, conserver power source has alarm when being lower than constrain height for water level simultaneously, has avoided the generation of fire.
Constant temperature water tank, comprise a water tank, and be positioned at the heating tube and the temperature sensor of water tank, it is characterized in that: be fixed with PID intelligence table in the water tank outside, described temperature sensor is electrically connected with PID intelligence table, and described PID intelligence table is electrically connected with heating tube by solid-state relay.
Be provided with liquid level meter in the described water tank, the water tank outside also is fixed with audible-visual annunciator, and described liquid level meter is electrically connected with audible-visual annunciator by auxiliary reclay, and described auxiliary reclay is electrically connected with solid-state relay.
The utility model has added PID intelligence table in original constant temperature water tank, this PID intelligence table is applicable to that various industrial process parameter measurements such as temperature, pressure, liquid level, flow show and accurately control.Set steady temperature by PID intelligence table, when water temperature in the water tank is lower than this design temperature, temperature sensor measurement is passed to PID intelligence table to measurement result, and PID intelligence table calculates the back by the solid-state relay control heater circuit working time, makes the work of heating tube interruption; According to water temperature in the water tank and design temperature relatively, PID intelligence table can be controlled heater circuit (electric heating tube) the work intermittent time by solid-state relay, since reach constant temperature.Because the accurate control of PID intelligence table makes the utility model constant temperature water tank control accuracy improve conserver power source.And the utility model adopts the duty (be heating work and do not heat stop) of solid-state relay control heater circuit, the homomorphism relay belongs to the general contact contactor relay of electronic seal device, and to have a life-span long, the spark that noiselessness, no electric contact produce, highly sensitive, conversion fast, advantages such as the little safety of electromagnetic interference.
The utility model also is provided with liquid level meter and audible-visual annunciator, liquid level meter detects the liquid level in the water tank, when liquid level is lower than the height of heating tube, by the caution of auxiliary reclay control sound and light alarm, auxiliary reclay is connected with the homomorphism relay makes solid-state relay not work, even and water temperature is lower than design temperature, do not start heating tube work yet; When liquid level is higher than the height of heating tube, and water temperature is lower than design temperature, and PID is by solid-state relay control heating tube work constant temperature.Sound and light alarm prompting water level does not reach safety level during the utility model lack of water, controls solid-state relay by auxiliary reclay, and lack of water stops heating, to prevent anhydrous dry combustion method, damages heating tube and eliminates disaster hidden-trouble.

The specific embodiment
Constant temperature water tank, comprise a water tank 1, and be positioned at heating tube 2, liquid level meter 3 and the temperature sensor 4 of water tank 1, be fixed with PID intelligence table 5 in water tank 1 outside, audible-visual annunciator 6 and indicator lamp 7, described indicator lamp 7, temperature sensor 4, liquid level meter 3 are electrically connected with PID intelligence table 5 respectively, and described PID intelligence table 5 is electrically connected with heating tube 2 by solid-state relay 8.
The utility model has added PID intelligence table 5 and audible-visual annunciator 6 in original constant temperature water tank, this PID intelligence table 5 is applicable to that various industrial process parameter measurements such as temperature, pressure, liquid level, flow show and accurately control.Set steady temperature by PID intelligence table 5, when water temperature is lower than this design temperature in the water tank 1, temperature sensor 4 is measured measurement result is passed to PID intelligence table 5, and PID intelligence table 5 opens or closes heater circuit by solid-state relay 8 controls and comes constant temperature, controls heating tube 2 duties; When water temperature was near design temperature in the water tank 1, same temperature sensor 8 was measured measurement result is passed to PID intelligence table 5, and PID intelligence table 5 makes heating tube 2 shorten heat time heating time by solid-state relay 8 control heater circuits; When water temperature reached design temperature in the water tank 1, temperature sensor 8 was measured measurement result is passed to PID intelligence table 5, and PID intelligence table 5 is by solid-state relay 8 control heater circuits, heating tube 2 was opened just in time maintain an equal level with the loss temperature heat time heating time promptly to reach constant temperature.Indicator lamp 7 bright expression electric heating tubes belong to the heating work state, and the indicator lamp 7 expression electric heating tube that do not work belongs to and do not heat halted state.It is bright that temperature is lower than the big duration of setting value, it is short that temperature is lower than the setting value hour corresponding 7 bright times of indicator lamp, temperature is lower than and equals to set value the bright interval of certain hour, the indicator lamp bright interval of 7 big durations certain hour and go out with constant temperature (being shown to control by PID), temperature do not work during greater than setting value (heating tube does not heat).
The utility model constant temperature water tank control accuracy improves, conserver power source; Sound and light alarm prompting water level reaches safety level during lack of water; Lack of water stops heating, to prevent anhydrous dry combustion method, damages heating tube.
