For solving the problems of the technologies described above, the present invention proposes a kind of steamer and automatically detect incrustation scale system, comprise steamer body and be arranged on the steam generator of steamer body lower end, some steam boxs and the jet chimney being communicated with described steam box and steam generator is provided with in described steamer body, described steamer body is provided with control device, the display be connected with control device and the timer be connected with control device, the pressure transducer for detecting pressure in jet chimney be connected with control device is provided with in described jet chimney, the temperature sensor be connected with control device is provided with in described steam generator, described jet chimney is provided with steam box link the intake valve be connected with control device.
Further, described jet chimney and steam generator link are provided with safety valve.
Further, described display is LED nixie display.
Further, described steam generator comprises water tank and is arranged on the electromagnetic coil disk of water tank bottom.
For solving the problems of the technologies described above, the invention allows for a kind of steamer and automatically detecting incrustation scale method, it is characterized in that, comprise the steps:
Step 1: power on, control device controls intake valve and cuts out, control steam generator with constant power work, when control device arrives fiducial temperature T0 by the water temperature that temperature sensor detects in water tank, stop heating, the pressure that this timed unit is detected in jet chimney by pressure transducer is P0 and preserves;
Step 2: control device controls steam generator to be continued with constant power work, and timer starts timing, heats after t minute and stops heating;
Step 3: the temperature detecting now Water in Water Tanks is T1 and preserves, and the pressure in jet chimney is P1 and preserves;
Step 4: control device calculates the water temperature difference DELTA T=T1-T0 of water tank automatically, the pressure difference DELTA P=P1-P0 of jet chimney;
Step 5: control device calculates coefficient value automatically by Δ T/ Δ P, and carries out comparing calculation with prefabricated parameter value, the result of contrast is shown over the display by code.
Further, described T0 equals 88 DEG C.
Technique scheme at least has following beneficial effect: hinge structure, the present invention is by the air pressure in control device record two sections of same time section internal steam pipe roads and the water temperature in water tank, in the draught head calculated in two sections of same time sections and differential water pressures, the accumulation degree of incrustation scale is judged by the changing value calculating draught head and differential water pressures, not only automatically can detect the situation of scale buildup in steamer, and improve the Efficiency and accuracy of incrustation scale detection, be convenient to remind and clean steam box in time, be conducive to energy-conservation.

Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below in conjunction with accompanying drawing, the present invention is described further.
Embodiment one
As shown in Figure 1, the steamer of the embodiment of the present invention automatically detects incrustation scale system and comprises steamer body 1, steam generator 2, steam box 11, control device 3, display 4, timer 5, pressure transducer 6, temperature sensor 7, intake valve 8.
Steam generator 2 is arranged on the lower end of steamer body 1, it electromagnetic coil disk comprising water tank and be arranged on water tank bottom, by electromagnetic coil disk, steam is produced to heating water tanks, the steam box 11 that 3 stack gradually installation is from top to bottom provided with in steamer body 1, the sidewall of steamer body 1 is provided with the jet chimney 12 being communicated with steam box 11 and water tank, the steam of such generation can enter in steam box 11 by jet chimney 12, and jet chimney 12 is provided with steam box 11 link the intake valve 8 be connected with control device 3; Pressure transducer 6 is arranged in jet chimney 12, it is connected with control device 3, and for sending the pressure information in the jet chimney 12 of acquisition to control device 3, temperature sensor 7 is arranged in water tank, it is connected with control device 3, for detecting the temperature of water in water tank.
When incrustation scale will be carried out to be detected, first after powering on, control device 3 controls intake valve 8 and cuts out, control steam generator 2 with constant power work, when control device 3 arrives fiducial temperature T0 by the water temperature that temperature sensor 7 detects in water tank, stop heating, the pressure that this timed unit 3 is detected in jet chimney 12 by pressure transducer 6 is P0 and preserves; Secondly, control device 3 controls steam generator 2 and continues with constant power work, and timer 5 starts timing, heats after t minute and stops heating; Then the temperature detecting now Water in Water Tanks is T1 and preserves, and the pressure in jet chimney 12 is P1 and preserves; This timed unit 3 calculates the water temperature difference DELTA T=T1-T0 of water tank automatically, the pressure difference DELTA P=P1-P0 of jet chimney 12; Last control device 3 calculates coefficient value automatically by Δ T/ Δ P, and carry out comparing calculation with prefabricated parameter value, the result of contrast is shown on display 4 by code, wherein, look into parameter list (see Fig. 3) with Δ T/ Δ P and draw steam box 11 incrustation scale degree, be divided into normal, have the very thick Three Estate of incrustation scale and incrustation scale, when showing normal value, illustrate that the use of incrustation scale on steamer does not almost affect; When showing incrustation scale, illustrating that the use of incrustation scale to steamer has a certain impact, needing cleaning; When showing incrustation scale and being very thick, illustrate that the use of incrustation scale to steamer has a great impact, use can cause result of use and experience extreme difference by force, must clean.
In order to ensure the security performance of steamer, being provided with safety valve 9 at jet chimney 12 and steam generator 2 link, like this when the air pressure in jet chimney 12 is excessive, pressure release can being carried out by safety valve 9, ensure the security performance of product.
Embodiment two
As shown in Figure 2, the steamer of the embodiment of the present invention automatically detects incrustation scale method and comprises the steps: step 1: power on, control device 3 controls intake valve 8 and cuts out, control steam generator 2 with constant power work, when control device 3 arrives fiducial temperature T0 (T0 equals 88 DEG C) by the water temperature that temperature sensor 7 detects in water tank, stop heating, the pressure that this timed unit 3 is detected in jet chimney 12 by pressure transducer 6 is P0 and preserves;
Step 2: control device 3 controls steam generator 2 and continues with constant power work, and timer 5 starts timing, heats after t minute and stops heating;
Step 3: the temperature detecting now Water in Water Tanks is T1 and preserves, and the pressure in jet chimney 12 is P1 and preserves;
Step 4: control device 3 calculates the water temperature difference DELTA T=T1-T0 of water tank automatically, the pressure difference DELTA P=P1-P0 of jet chimney 12;
Step 5: control device 3 calculates coefficient value automatically by Δ T/ Δ P, and carries out comparing calculation with prefabricated parameter value, the result of contrast is shown on display 4 by code.
The above is the specific embodiment of the present invention, it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also make some amendments, and these amendments are also considered as protection scope of the present invention.
