In other embodiments, the water level detection device 9 may also be another water level detector capable of continuously detecting the highest water level and the lowest water temperature of the preheating water tank 3; or two water level detection devices 9 arranged up and down are arranged on the inner side wall of the preheating water tank 3, wherein the upper water level detection device 9 is used for monitoring the highest water level (namely full water level) of the preheating water tank 3 and controlling the closing of the water pump 8 so as to stop supplying water to the preheating water tank 3; the lower water level detection device 9 is used for monitoring the lowest water level of the preheating water tank 3 and controlling the starting of the water pump 8 so as to supply water to the preheating water tank 3 and avoid the water shortage phenomenon of the preheating water tank 3.
The working principle of the steam system of the present embodiment is explained below with reference to fig. 1:
before starting the steam system, the water storage tank 7 is in a full water state, no water exists in the evaporation cavity 11 and the preheating water tank 3, at the moment, the floater 5 sinks, and the control valve 4 opens the water outlet 31. The steam system is started, the water pump 8 starts to pump water, water flows into the evaporation cavity 11 from the preheating water tank 3 due to the fact that the water outlet 31 is in an opening state, the floater 5 floats upwards along with the rising of the water level of the evaporator, when the water in the evaporation cavity 11 rises to a certain water level, the floater 5 floats upwards and drives the control valve 4 to move downwards through the transmission assembly 6 to close the water outlet 31, at the moment, the water pump 8 continues to pump water to the preheating water tank 3, and when the water level detection device 9 detects that the preheating water tank 3 is full of water, the controller controls the water pump 8 to stop pumping water according to signals sent by the water level detection device 9.
As shown in fig. 1, the heating device 2 is activated, the water in the evaporation chamber 11 is heated until boiling, and during the heating and boiling process of the water in the evaporation chamber 11, the water in the preheating water tank 3 is heated to near boiling or to boiling by heat transfer. As the steam continues to be output, the water level in the evaporation chamber 11 drops and the float 5 floats.
When the floater 5 descends to the water replenishing level without dry burning along with the water level of the evaporation cavity 11, the floater 5 drives the control valve 4 to move upwards and open the water outlet 31 through the transmission assembly 6, hot water in the preheating water tank 3 can be rapidly heated to boil after rushing into the evaporation cavity 11, so that the evaporation cavity 11 uninterruptedly produces steam, the dry burning of the evaporation cavity 11 can be avoided, and the service life of the evaporator 1 is prolonged. And simultaneously, the water level detection device 9 starts timing when detecting that the water level of the preheating water tank 3 is lower than a preset water level threshold value.
Along with the preheating water tank 3 replenishes water to the evaporation cavity 11, the floater 5 floats upwards along with the water level rise of the evaporation cavity 11, the floater 5 firstly buffers for a period of time and then pushes the connecting rod 62 to rotate clockwise, the connecting rod 62 firstly moves downwards along the vertical strip-shaped hole 421 of the first connecting part 42, and then the control valve 4 is pulled to slowly move downwards, so that the preheating water tank 3 has enough time to continue to replenish water to the evaporation cavity 11 to the full water level. When the timing duration reaches the preset time, the water level of the evaporation cavity 11 is filled, the control valve 4 closes the water outlet 31, the water pump 8 is controlled to start to pump water to the preheating water tank 3 at the moment, and in the water pumping process, because the water outlet 31 is in a closed state, newly injected cold water can not directly flow into the evaporation cavity 11 without preheating, so that steam stagnation can not occur.
When the water level detection device 9 detects that the water level of the preheating water tank 3 reaches the preset water level threshold value along with the process of pumping water from the water pump 8 to the preheating water tank 3, the water pump 8 is controlled to stop pumping water.
It can be seen that the steam system of this embodiment, simple structure, low in manufacturing cost, in whole steam procedure, can be automatically to the supplementary hot water of evaporation chamber 11, avoid evaporation chamber 11 to take place dry combustion method. Meanwhile, the water replenishing of the evaporation cavity 11 can be quickly heated to boiling, the steam production efficiency is high, and the continuous and uninterrupted steam production is ensured.
The present embodiment also provides a household appliance having a steam system as described above. Further, the household appliance is any one of a steam box, an oven and a steaming and baking all-in-one machine.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
