The design of the length of 0.2m to 1.5m ensures that the steam generated in the liquid storage cavity 102 can be completely liquefied into small liquid beads in the channel 106, and forms a steam effect of 'white smoke', thereby ensuring that the steam exhausted through the opening 108 is the steam of 'white smoke'.
Specifically, the length of the channel 106 refers to the length of the channel 106 in the axial direction, i.e. the distance the steam needs to flow within the channel 106. Specifically, the length of the channel 106 may be 0.2m, 0.5m, 0.8m, 1.0m, 1.2m, 1.5m, etc., and may be designed according to the size or product model of the liquid storage chamber 102.
In addition, the steam generating device according to the present embodiment has all the advantages as the steam generating device according to the first embodiment, and the description thereof will not be repeated here.
Embodiment III:
as shown in fig. 1, 2 and 3, a third embodiment of the present invention provides a steam generating apparatus, comprising: a reservoir 102 and a heating element 104.
The liquid storage cavity 102 can store liquid, and the heating element 104 is disposed in the liquid storage cavity 102 and can supply heat to the liquid storage cavity 102. In particular, when the liquid level H in the liquid storage chamber 102 is at the preset liquid level, a part of the heating element 104 is located below the liquid level H, and another part is located above the liquid level H. That is, during operation of the steam generator, the level H of the liquid in the liquid storage chamber 102 is at the middle of the heating element 104, so that a portion of the heating element 104 is below the level H and another portion is above the level H.
Further, as shown in FIG. 4, the ratio of the height of the portion of the heating member 104 below the preset liquid level to the total height of the heating member 104 is greater than or less than 1/2 and less than or equal to 3/4. That is, as shown in FIG. 4, in use, the height of the portion of the heating element 104 below the liquid level H is L1, and the total height of the heating element 104 is L2, satisfying 1/2.ltoreq.L1/L2.ltoreq.3/4.
It is noted that the portion of the heating element 104 below the liquid level H is used to heat the liquid and generate steam, and the portion of the heating element 104 above the liquid level H is used to heat the steam and generate superheated steam. Thus, by defining the ratio of the height L1 of the portion located partly below the liquid level H to the total height L2 of the heating member 104, i.e. the relation between the amount of steam generated and the part of the heating member 104 that re-heats the steam is defined.
Specifically, by limiting the ratio of the height L1 of the portion of the heating element 104 below the preset liquid level to the total height L2 of the heating element 104 to be greater than or less than 1/2 and less than or equal to 3/4, the amount of generated normal-temperature steam can be ensured to be matched with the amount of generated normal-temperature steam located above the preset liquid level for heating the normal-temperature steam heating element 104, so that the steam generated by the liquid can be heated again, and the steam generation device can generate as much steam as possible.
In addition, the steam generating device according to the present embodiment has all the advantages as the steam generating device according to the first embodiment, and the description thereof will not be repeated here.
Embodiment four:
as shown in fig. 1, 2 and 3, a fourth embodiment of the present invention provides a steam generating apparatus, including: the reservoir 102, the heating element 104, the detection device 110, and the controller 124.
The liquid storage cavity 102 can store liquid, and the heating element 104 is disposed in the liquid storage cavity 102 and can supply heat to the liquid storage cavity 102. In particular, when the liquid level H in the liquid storage chamber 102 is at the preset liquid level, a part of the heating element 104 is located below the liquid level H, and another part is located above the liquid level H. That is, during operation of the steam generator, the level H of the liquid in the liquid storage chamber 102 is at the middle of the heating element 104, so that a portion of the heating element 104 is below the level H and another portion is above the level H.
In addition, as shown in fig. 1, 2, 6 and 7, the steam generating device further includes a detecting device 110 and a controller 124. The detection device 110 is used in cooperation with the controller 124, and is configured to detect a current liquid level in the liquid storage cavity 102, and send a detection result to the controller 124; after the controller 124 obtains the detection result of the detection device 110, it determines whether the current liquid level in the liquid storage cavity 102 is at the preset liquid level, and controls the steam generating device to operate according to the control result.
Specifically, the controller 124 may control the heating element 104 to operate when the current liquid level is at the preset liquid level and may control the heating element 104 to stop operating when the current liquid level is not at the preset liquid level. In addition, the controller 124 may also issue an alarm to prompt the user when the current liquid level is not at the preset liquid level. Further, the controller 124 may also control the liquid storage chamber 102 to be supplied with water when the current liquid level is not at the preset liquid level, so that the liquid level H in the liquid storage chamber 102 is at the preset liquid level.
Specifically, as shown in fig. 6 and 7, the detection device 110 may employ a temperature controller and be disposed near a preset liquid level, and the liquid level H in the liquid storage chamber 102 is obtained by detecting the temperature. Specifically, the thermostat may detect the temperature inside the reservoir 102. When the liquid level H in the liquid storage cavity 102 is at the preset liquid level, the duty ratio of the part of the heating element 104 located below the liquid level H and the heating element 104 located above the liquid level H and in the dry heating state is in a certain range, the temperature in the liquid storage cavity 102 is also in a certain temperature interval, and at this time, the temperature controller is in a communicating state, and the controller 124 controls the heating element 104 to work. When the liquid level H in the liquid storage chamber 102 is lower than the preset liquid level, the duty ratio of the heating element 104 in the dry combustion state above the liquid level H is increased, so that the temperature in the liquid storage chamber 102 is increased and is higher than the upper limit value of the temperature interval, and the temperature controller is in the off state at this time, and the controller 124 controls the heating element 104 to stop working. When the liquid level H in the liquid storage chamber 102 is higher than the preset liquid level, the duty ratio of the heating element 104 in the dry combustion state above the liquid level H is reduced, so that the temperature in the liquid storage chamber 102 is reduced and is lower than the lower limit value of the temperature interval, and the temperature controller is in the off state at this time, and the controller 124 controls the heating element 104 to stop working.
Specifically, the detection device 110 may employ a liquid level sensor, and is disposed near a preset liquid level, and directly detects the liquid level H in the liquid storage chamber 102. Specifically, when the current liquid level H is at the preset liquid level, the liquid level sensor is in a connected state, and the controller 124 controls the heating element 104 to operate. When the liquid level H in the liquid storage chamber 102 is lower than the preset liquid level, the liquid level sensor is in an off state, and the controller 124 controls the heating element 104 to stop working. When the liquid level H in the liquid storage chamber 102 is higher than the preset liquid level, the liquid level sensor is in an off state, and the controller 124 controls the heating element 104 to stop working.
In this embodiment, as shown in fig. 6 and 7, further, the heating member 104 is disposed partially above the detecting position of the detecting device 110 and partially below the detecting position of the detecting device 110. That is, the detecting position of the detecting device 110 is located in the middle of the heating member 104. By the design, the detection device 110 is matched with the controller 124, so that the liquid level H in the liquid storage cavity 102 is ensured to be positioned in the middle of the heating element 104, a part of the heating element 104 is positioned below the liquid level H, and a part of the heating element 104 is positioned below the liquid level H, so that the generation of superheated steam is ensured.
In this embodiment, further, as shown in fig. 6 and 7, the detecting position of the detecting device 110 is located in the middle of the heating member 104; the ratio of the height of the portion of the heating member 104 located below the detection position to the total height of the heating member 104 is greater than or less than 1/2 and less than or equal to 3/4. That is, in the height direction of the steam generating device, it is ensured that the detecting means 110 is located at 1/2 to 3/4 of the height of the heating member 104. More specifically, it is ensured that the height of the detection means 110 is level with the height of the preset liquid level.
Particularly, when the liquid in the liquid storage cavity 102 is sufficient and the liquid level H is 1/2 to 3/4 of the height of the heating element 104 during the use of the steam generating device, a part of the heating element 104 is ensured to be positioned below the liquid level H, and another part is ensured to be positioned above the liquid level H, so that a good white smoke effect is ensured, and the heating element 104 is controlled to work normally at the moment. When the liquid in the liquid storage cavity 102 is insufficient and the liquid level H is lower than 1/2 to 3/4 of the height of the heating element 104, the steam generating device cannot generate the steam effect of white smoke at this time, and the heating element 104 is controlled to stop working.
That is, based on the cooperation of the detection device 110 and the heating element 104, it is ensured that a part of the heating element 104 is always below the liquid level H and a part of the heating element is above the liquid level H, and the steam generating device can generate the steam effect of the natural steam and the white smoke.
In addition, the steam generating device according to the present embodiment has all the advantages as the steam generating device according to the first embodiment, and the description thereof will not be repeated here.
