Please refer to the drawing 1, the bottom type steam raising plant 100 of better embodiment of the present invention comprises steam generator 102, water tank 104, magnetic valve 106 and controller 108.Bottom type steam raising plant 100 can be applicable to the household electrical appliance such as steam cooking apparatus, the water dispenser of band water box, the coffee machine of band water box.
The heater 112 that this steam generator 102 comprises water container 110 and is connected with water container 110, water container 110 is for the water of accommodating evaporation.Water container 110 is arranged at the bottom of bottom type steam raising plant 100, and the water vapour being convenient to steam generator 102 enters the cooking cavity 114 li of bottom type steam raising plant 100.
This heater 112 is for heating this water container 110.Heater 112 can be electric heating tube, and it is arranged at the bottom of water container 110.Heater 112 is energized or power-off can make heater 112 heat or stop heat water container 110.
This water tank 104 is for supplying water to this water container 110.Water tank 104 is arranged at the side at cooking cavity 114, and is connected with water container 110 by water pipe 116.Preferably, the position of this water container 110 lower than the position of this water tank 104, so, the water of water tank 104 by the height of water between water tank 104 and water container 11 all or major part enter in water container 110, improve the utilization rate of water.
This magnetic valve 106 connects this water container 110 and this water tank 104 and break-make for controlling the water route between this water container 110 and this water tank 104.Such as, magnetic valve 106 is connected with water container 110 and water tank 104 by water pipe 116, and the break-make of magnetic valve 106 controls the break-make in the water route between this water container 110 and this water tank 104, and then the water yield that control water tank 104 supplies water to water container 110.
This controller 108 for opening and cutting out this heater 112, and opens and cuts out this magnetic valve 106, and after this heater 112 of unlatching, every setting-up time, adjusts the make-to-break ratio of this magnetic valve 106.
Particularly, please refer to the drawing 2, controller 108 comprises heater control module 118 and solenoid valve control module 120.
This heater control module 118 is for opening or closing this heater 112.Heater control module 118 can work according to the mode of operation control heater 112 of setting.
This solenoid valve control module 120 for opening or closing this magnetic valve 106, and after this heater control module 118 opens this heater 112, every setting-up time, adjusts the make-to-break ratio of this magnetic valve 106.
Such as, when bottom type steam raising plant 100 works at the beginning, solenoid valve control module 120 opens solenoid valve 106, water tank 104 is made in water container 110, to be filled with certain water yield in advance with the suitable water level of pre-generated one, now, heater control module 118 can open simultaneously or etc. to send after water heater 112 after a while.
Can be stored in memory 122 to the adjustment parameter that this magnetic valve 106 carries out make-to-break ratio adjustment, memory 122 can integrate to save space with controller 108.This solenoid valve control module 120 is according to the make-to-break ratio of this this magnetic valve 106 of adjustment parameter adjustment.
In present embodiment, because bottom type steam raising plant 100 adopts the height of water between water tank 104 and water container 110 to supply water, so, along with the increase of bottom type steam raising plant 100 running time, the water of water tank 104 can be fewer and feweri, its height of water also can become more and more less, if now magnetic valve 106 adopts fixing make-to-break ratio to carry out work, the water certainty be then supplied in water container 110 also can be fewer and feweri, even after the water in water container 110 is digested completely by generator already, just likely there is the situation of dry combustion method in water container 110.
So as shown in Figure 3, every setting-up time after heater control module 118 heater, solenoid valve control module 120 just once can adjust the make-to-break ratio of magnetic valve 106.Particularly, solenoid valve control module 120 controls adjustment parameter and often crosses setting-up time (this time can be determined according to the maximum of the parameters of operating part of bottom type steam raising plant 100 and the height of water and minimum of a value), increases by 1 time quantum (typical example is 1 second).Solenoid valve control module 120, according to this adjustment parameter, is carried out plus and minus calculation with this adjustment parameter by the make-to-break ratio parameter that magnetic valve 106 is current, thus is obtained the make-to-break ratio of new suitable magnetic valve 106.The make-to-break ratio parameter of magnetic valve 106 comprises opening time and the shut-in time of magnetic valve 106.
Such as, along with the increase of heater 112 running time, adjustment parameter was every 10 minutes, increase by 1 second, solenoid valve control module 120 according to this adjustment parameter, every 10 minutes, the shut-in time of magnetic valve 106 deducts 1 second, and then increases the make-to-break ratio of magnetic valve 106, maintain stable water supply.
In present embodiment, this bottom type steam raising plant 100 comprises timer 124, and this timer 124 connects this controller 108, and this controller 108, for when opening this heater 112, controlling this timer 124 and starting timing.Timer 124 can be count-down device that bottom type steam raising plant 100 itself adopts or, newly-increased independent timer.Timer 124 can integrate with controller 108.Timer 124 starts timing after product cooking process comes into operation, after reaching certain accumulation timing (as 10 minutes), the make-to-break ratio of solenoid valve control module 120 pairs of magnetic valves 106 carries out the adjustment of forward increase, and afterwards, timer 124 resets and restarts timing.
In actual applications, please refer to the drawing 3, in the running of bottom type steam raising plant 100, in water tank 104, the height of water declines not is that straight line changes, because water level decreasing causes magnetic valve 106 when identical make-to-break ratio, the output of water tank 104 diminishes, so water tank 104 water level decreasing will be slack-off, simultaneously, due to the setting of supplying water be must meet the harshest situation under the needs of (when the such as height of water is close to lowest water level drop), so generally magnetic valve 106 is all based on break-make work, the water level in water container 110 will be caused like this to have a little fluctuation because of this break-make way of supplying water.
More specifically, if the power of steam generator 102 is 1800W, magnetic valve 106 all-pass and the water supply capacity of water level bottom type steam raising plant 100 when peak level drop hypothesis be 3ml/s, so, if the water at the beginning in water tank 104 is full (i.e. peak level drop), the make-to-break ratio of magnetic valve 106 can be set to ON:2s/OFF:28s.If the water flow of magnetic valve 106 itself is set to, 1.5ml/s when lowest water level drop, so, when the water in water tank 104 is close to lowest water level drop, the make-to-break ratio of magnetic valve 106 now should be set to ON:2s/OFF:13s could allow the water supply of water tank 104 and water tank 104 full water time suitable state.And in the process from water tank 104 full water to water level close to lowest water level drop, the namely ever-increasing process of this make-to-break ratio of magnetic valve 106.Such as, if need through 60 minutes (i.e. water consumption 0.2ml/s) to (supposing that this process water loss is 720 milliliters) the process of water level close to lowest water level drop water tank 104 is full from water, so, bottom type steam raising plant 100 is every 10 minutes, reduce 3 seconds shut-in times of the magnetic valve 106 in the make-to-break ratio parameter of magnetic valve 106, namely within the 50th minute, 15 seconds are just subtracted, to meet the requirement of the stable water supply of bottom type steam raising plant 100.
It is pointed out that in the control procedure of above-mentioned citing, bottom type steam raising plant 100 is when starting working, and the starting position of the water level of water tank 104 is full water positions.But in actual applications, user may may not feed-tank 104 topped up with water just allow bottom type steam raising plant 100 start working.Therefore, the starting position of the water level of water tank 104 is not full water position sometimes.
So, for making bottom type steam raising plant 100 more realistic, range of application is wider, in the present embodiment, this bottom type steam raising plant 100 comprises condensate tank of dehumidifier 126, this condensate tank of dehumidifier 126 is for detecting the water level of this water tank 104, and this controller 108, for the water level according to this water tank 104 detected, adjusts the make-to-break ratio of this magnetic valve 106.
In present embodiment, condensate tank of dehumidifier 126 is level sensor, and level sensor can be placed in water tank 104, to detect the water level of water tank 104 in real time.In other embodiments, condensate tank of dehumidifier 126 can be weight sensor, and it is outer and detect the weight of water tank that weight sensor can be arranged at water tank 104, and solenoid valve control module 120 judges water level position by the weight of water tank 104.
Afterwards, solenoid valve control module 120 adjusts the make-to-break ratio of magnetic valve 106 according to water level position, and such as, solenoid valve control module 120 calculates the time needed reducing the turn-off time of magnetic valve 106.Such as, during beginning, if the water level that condensate tank of dehumidifier 126 is measured only has the height of full water position half, so, solenoid valve control module 120 will reduce 3 seconds to the shut-in time of magnetic valve 106 in 10 minutes in first time, reduces 4 seconds, by that analogy after next 10 minutes.
In sum, in above-mentioned bottom type steam raising plant 100, along with the increase of heater 112 working time, controller 108 adjusts by the make-to-break ratio adjusting magnetic valve 106 water yield that water tank 104 flows into water container 110, and then realize adjustment water container 110 middle water level height, make properties of product more stable, not dry combustion method, steam generator 102 works more reliable.Meanwhile, if bottom type steam raising plant 100 does not have extra condensate tank of dehumidifier 126, can system complexity be reduced, avoid the production fraction defective caused due to the quality problem of each parts own during volume production to rise.
