Detailed Description
The invention is described in further detail below with reference to the accompanying examples.
As shown in fig. 1, the steam system of the double-inner-container steam box of the present embodiment includes a steam generator 1, a steam valve 2, a first inner container 3, a second inner container 4, an air guide assembly 5, and a safety valve 6. Wherein, steam generator 1 has two gas outlets, steam valve 2 has two gas inlets and two gas outlets, two gas outlets of steam generator 1 are linked together with two gas inlets of steam valve 2 respectively, two gas outlets of steam valve 2 are linked together with the gas inlet of first inner bag 3 and second inner bag 4 respectively, the gas outlet of first inner bag 3 and second inner bag 4 communicates respectively with two air inlets of air guide component 5, air guide component 5's gas vent is linked together with the steam ager exterior space. The connecting structure of the steam pipeline is the same as that of the existing double-inner-container steam box.
In this embodiment, the steam generator 1 at the air inlet of the safety valve 6 is communicated with the pipeline between the steam valve 2, and the air outlet of the safety valve 6 is communicated with the pipeline between the steam valve 2 and the first inner container 3.
Install first temperature sensor in the first inner bag 3, install second temperature sensor in the second inner bag 4, the steam ager is including controller and control interface, first temperature sensor and second temperature sensor's signal output part with the signal input part looks electricity of controller is connected, and control interface can show according to the output signal of controller the suggestion of the corresponding trouble of steam valve. Therefore, the control interface of the steam box can display the corresponding fault of the steam valve according to the temperature rise condition of the inner container.
Assuming that the set pressure value of the safety valve 6 is P1, when the steam valve 2 works normally (functions are normal, and the steam valve is not blocked or sealed tightly), the steam pressure value at the front end of the steam valve 2 is P2, P1 is sx P2, and S is a safety coefficient, and the suggested value is 3-6. When the steam valve 2 works normally, the steam pressure P at the front end of the steam valve 2 is not more than P2; when the steam valve 2 is blocked, when the steam pressure P at the front end of the steam valve 2 is more than or equal to P1, the safety valve 6 starts to work, and the steam generated by the steam generator 1 enters the first inner container 3 through the safety valve (without passing through the steam valve). To ensure that the pressure release rate is not lower than the steam generation rate of the steam generator 1, the inner diameter of the valve port of the safety valve 6 needs to be as large as possible, which will not cause the pressure in the steam generator 1 to increase further.
As shown in fig. 2, the method for detecting the steam valve fault of the steam system of the double-liner steam box according to the embodiment detects different operating states of the steam valve 2 as follows:
when the steam valve 2 works normally, the safety valve 6 does not work, and the first inner container 3 and the second inner container 4 are heated normally;
when the steam valve 2 is blocked, the safety valve 6 works, and steam enters the first inner container 3 through the safety valve 6; if the working mode of the steam box at the moment is that the second inner container 4 works alone or the first inner container 3 and the second inner container 4 work simultaneously, the temperature of the first inner container 3 is normally increased, the temperature of the second inner container 4 is not increased, the control interface prompts a fault prompt that the steam valve 2 is blocked, and the steam generator 1 stops heating; if the working mode of steam ager this moment is first inner bag 3 and works alone, can't show the trouble temporarily, nevertheless first inner bag 3 culinary art performance is not influenced, waits to use second inner bag 4 next time, and control interface shows that steam valve 2 blocks up dead trouble suggestion.
When the steam valve 2 is not tightly sealed, the safety valve 6 does not work, if the first inner container 3 works independently and the steam valve interface connected to the second inner container 4 is not tightly sealed, the temperature of the first inner container 3 is normally raised, the temperature of the second inner container 4 is slowly raised, the second temperature sensor detects the slow temperature-raising condition of the second inner container 4, and the control interface displays the fault prompt that the steam valve 2 is not tightly sealed.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications or improvements may be made to the present invention without departing from the principle of the present invention, for example, the outlet of the safety valve may also be communicated with the pipeline between the steam valve and the second inner container, which are considered to be within the protection scope of the present invention.
