Next, a scale detection method according to an embodiment of the first aspect of the present invention will be described with reference to the accompanying drawings.

The scale detection method is used for the steam generator 1, and the scale detection method may be used for performing scale detection on the steam generator 1 to determine whether the steam generator 1 needs descaling. Wherein, the steam generator 1 comprises a water level detection assembly 11, and the water level detection assembly 11 is used for acquiring water level information in the steam generator 1.

The water level detecting assembly 11 includes a plurality of water level detecting devices each having a probe for sensing water level information. The water level detecting assembly 11 includes a first water level detecting device 111 and a second water level detecting device 112, the first water level detecting device 111 is used for detecting whether the water level reaches a first water level height, if the water level reaches the first water level height, a first probe 111a of the first water level detecting device 111 can sense water level information, and can trigger the first water level detecting device 111 to generate a corresponding signal, at this time, the first water level detecting device 111 acquires the water level information, if the water level does not reach the first water level height, the first probe 111a cannot sense the water level information, the first water level detecting device 111 cannot generate a corresponding signal, at this time, the first water level detecting device 111 does not acquire the water level information; the second water level detecting device 112 is used for detecting whether the water level reaches a second water level height, if the water level reaches the second water level height, the second probe 112a of the second water level detecting device 112 can sense the water level information, and can trigger the second water level detecting device 112 to generate a corresponding signal, at this moment, the second water level detecting device 112 acquires the water level information, if the water level does not reach the second water level height, the second probe 112a cannot sense the water level information, the second water level detecting device 112 cannot generate a corresponding signal, at this moment, the second water level detecting device 112 does not acquire the water level information. Wherein the first water level is lower than the second water level.

It should be noted that, in the description of the present application, "a plurality" means two or more. The number of the water level detection devices may be two or more.

As shown in fig. 1 to 3, the scale detection method includes the steps of: s1: the water level detection assembly 11 acquires water level information in the steam generator 1, for example, drives an input pulse to the water level detection assembly 11 to control the water level detection assembly 11 to acquire the water level information, the input of the pulse may be performed by a user or may be performed by the control device 2 described later, but is not limited thereto; s2: if the first water level detecting device 111 does not acquire the water level information and the second water level detecting device 112 acquires the water level information, it is determined that the steam generator 1 needs to remove the scale. Therefore, whether the steam generator 1 needs descaling or not is judged according to whether the first water level detection device 111 and the second water level detection device 112 obtain effective water level information or not, and automatic scale detection is realized; compared with the prior art, the scale removal method has the advantages that the user is reminded of removing scale when the steam generator operates, the scale detection method is more accurate and practical, and scale detection logic is simple and convenient to realize.

It should be noted that, because the probe of the water level detection device is disposed in the steam generator 1, and the probe of the water level detection device needs to contact with water to obtain water level information, and the first water level height is smaller than the second water level height, which can indicate that the height of the first probe 111a is lower than the height of the second probe 112a in the up-down direction, the first probe 111a is located below the second probe 112a, for example, the first probe 111a may be located directly below the second probe 112a, or the first probe 111a may be located obliquely below the second probe 112a, so that the scale on the inner wall surface of the steam generator 1 is substantially equivalent to the scale on the surface of the first probe 111a, and the excessive scale on the surface of the first probe 111a means that the scale on the inner wall surface of the steam generator 1 is excessive, and if the scale on the surface of the first probe 111a is excessive scale, the outer surface of the first probe 111a is completely covered by the scale, so that the first water level detection device 111 fails to obtain the water level information in the steam generator 1, and then the steam generator 1 needs to descale. From this, at first water level detection device 111 not acquireing water level information, and when second water level detection device 112 acquireed water level information, it indicates that sufficient water has and the water level has reached second water level height in steam generator 1, it can't acquire water level information because of anhydrous, that lack of water etc. leads to have got rid of first water level detection device 111, indicate then that first probe 111a surface incrustation scale is more, make first water level detection device 111 inefficacy, can confirm that steam generator 1 needs the scale removal this moment, thereby through the incrustation scale accumulation's on water level detection subassembly 11 surface degree, come the indirect judgement steam generator 1 interior incrustation scale whether accumulated the degree that needs the scale removal.

According to the scale detection method provided by the embodiment of the invention, when the first water level detection device 111 does not acquire water level information and the second water level detection device 112 acquires the water level information, the scale of the steam generator 1 is determined to be descaled, so that the automatic detection of the scale of the steam generator 1 can be realized, whether the scale of the steam generator 1 needs to be descaled or not is automatically determined, the logic is simple, the realization is convenient, meanwhile, the condition that no water or little water exists in the steam generator 1 affects the detection accuracy of the water level detection assembly 11 can be eliminated, certain judgment accuracy is realized, the water level detection assembly 11 in the steam generator 1 can be adopted, and the convenience in scale detection is favorably improved.

From this, when steam generator 1 is applied to steam cooking utensil, can realize whether the automatic determination of steam cooking utensil needs the scale removal, can avoid steam generator 1 interior water spot more, promoted user's convenience in use, and be convenient for guarantee steam cooking utensil's intensification speed, promote food taste, guarantee that steam generator 1 uses reliably, can avoid protruding formula temperature controller frequency disconnection scheduling problem simultaneously, guarantee steam cooking utensil reliable operation.

In some embodiments of the present invention, as shown in fig. 2 and 3, the water level detecting assembly 11 obtains the water level information, and if the water level information is obtained by the first water level detecting device 111 or the water level information is obtained by both the first water level detecting device 111 and the second water level detecting device 112, it can indicate that the scale on the surface of the first water level detecting device 111 is less or substantially no scale, and at the same time, it is determined that the scale removal of the steam generator 1 is not needed, which means that the scale on the inner wall surface of the steam generator 1 is less or substantially no scale. Thereby, a simple judgment logic is provided for determining whether the steam generator 1 needs descaling.

In some embodiments of the present invention, as shown in fig. 3, the scale detection method further includes: after determining that the steam generator 1 needs descaling, it indicates that the scale may affect the normal operation of the steam generator 1, and then remind the user of descaling, and the user may perform corresponding processing according to the reminding information, for example, the user may suspend using the steam generator 1 first and descale the steam generator 1, or the user may replace the steam generator 1, and so on, so as to avoid that the user still continues to use the steam generator 1 when the scale of the steam generator 1 is more, which results in lower steam generation efficiency, higher power consumption, and so on, and thus the performance of the steam generator 1 can be always maintained in an optimal state, and the service life of the steam generator 1 is effectively ensured.

It is understood that the user may be alerted to descale the steam generator 1 by at least one of an acoustic signal, a light signal, displayed text and displayed patterns; for example, the light-emitting device can emit a prompt light, and the user can know that the scale in the steam generator 1 is more and needs to be removed when seeing the prompt light information; for example, a prompt sound can be sent by the sound-producing device, and a user can know that the scale in the steam generator 1 is more and needs to be removed by hearing the prompt sound information; for example, display information such as characters or patterns can be displayed through the display device, and a user can know that the scale in the steam generator 1 is more and needs to be removed by seeing the display information; for example, the user may also be alerted by a combination of any of an acoustic signal, a light signal, a display question, and a display pattern.

Optionally, after determining that the steam generator 1 needs to be descaled, the steam generator 1 may stop operating, and if the steam generator 1 does not operate before performing the scale detection, the steam generator 1 still maintains the stopped operating state after determining that the steam generator 1 needs to be descaled; if the steam generator 1 is in operation before the scale detection is performed, the steam generator 1 may be stopped after it is determined that the steam generator 1 needs to be descaled. The steam generator 1 is stopped, and the steam generator 1 may be turned off by a user, or the control device 2 may control the steam generator 1 to be turned off.

In some embodiments of the present invention, as shown in fig. 3, the water level detecting method further includes: after determining that the steam generator 1 does not need descaling, the steam generator 1 normally operates, and at this time, the scale does not have a great influence on the steam generator 1, so as to ensure the normal operation of the steam generator 1. Here, "normal operation of the steam generator 1" is to be understood as meaning that the steam generator 1 operates according to its own operating logic.

For example, the steam generator 1 may have an operating mode and a scale detection mode, and the steam generator 1 may be switchable between the operating mode and the scale detection mode, i.e. the steam generator 1 may be switched from the operating mode to the scale detection mode, or from the scale detection mode to the operating mode; in the scale detection mode, it is determined whether the steam generator 1 requires descaling using a scale detection method, and after it is determined that the steam generator 1 does not require descaling, the steam generator 1 may be switched to the operation mode. For example, the steam generator 1 may be connected to a water pumping means for pumping water from the water supply means into the steam generator 1, and the operation of the water pumping means may be controlled to ensure that the water level in the steam generator 1 is maintained substantially within a certain height range when the steam generator 1 is in the operational mode.

In some embodiments of the present invention, the steps S1 to S2 are performed every predetermined time, and then the scale detection is performed on the steam generator 1 every predetermined time, so as to determine whether the steam generator 1 needs to be descaled in time, which is beneficial to avoid the situation that the steam generator 1 continues to operate due to excessive scale in the steam generator 1.

It is understood that the predetermined time may be determined according to the volume of the steam generator 1, the water quality, etc.

In some embodiments of the present invention, the above steps S1 to S2 are performed each time the steam generator 1 is turned on, so as to determine whether the steam generator 1 needs to be descaled in time, thereby preventing the situation that the scale in the steam generator 1 is excessive and the steam generator 11 is still continuously operated for a long time.

In some embodiments of the invention, the scale detection method further comprises: before the step S1, water is continuously added into the steam generator 1, so that the normal operation of the steam generator 1 can be ensured while the steam generator 1 performs scale detection, and the water level in the steam generator 1 is conveniently ensured to be within a certain water level threshold or a certain water level height range; and after determining that the steam generator 1 needs to be descaled, stopping adding water so as to facilitate corresponding treatment of a user.

It can be understood that, when the scale detection method includes "reminding the user of removing scale after determining that the steam generator 1 needs to remove scale" and "stopping adding water after determining that the steam generator 1 needs to remove scale", after determining that the steam generator 1 needs to remove scale, "reminding the user of removing scale" and "stopping adding water" may be performed simultaneously or sequentially according to a certain sequence, for example, the adding water may be stopped first and then the user is reminded of removing scale, or the user may be reminded of removing scale first and then the adding water is stopped.

Next, a steam generation system 100 according to an embodiment of the second aspect of the present invention is described with reference to the drawings.

The steam generating system 100 according to the second embodiment of the present invention comprises a memory, a processor and a scale detection program stored in the memory and operable on the processor, wherein the processor implements the scale detection method according to the above-mentioned embodiment when the processor executes the scale detection program. Specifically, the scale detection method is stored in the memory in the form of a program, and when the scale detection is required, the processor executes the scale detection program to implement the scale detection method according to the above embodiment of the present invention.

According to the steam generation system 100 of the embodiment of the invention, by adopting the scale detection method, the automatic scale detection of the steam generator 1 can be realized, so as to automatically determine whether the steam generator 1 needs to be descaled, and facilitate the corresponding treatment of a user.

Next, a steam generation system 100 according to an embodiment of the third aspect of the present invention is described with reference to the drawings.

A steam generating system 100 according to a third embodiment of the present invention, as shown in fig. 4, includes a steam generator 1 and a control device 2, the steam generator 1 includes a water level detecting assembly 11, the water level detecting assembly 11 is used for acquiring water level information in the steam generator 1, the water level detecting assembly 11 includes a plurality of water level detecting devices, each of the water level detecting devices has a probe for sensing the water level information.

The water level detecting assembly 11 includes a first water level detecting device 111 and a second water level detecting device 112, the first water level detecting device 111 is used for detecting whether the water level reaches a first water level height, and the second water level detecting device 112 is used for detecting whether the water level reaches a second water level height. Wherein the first water level is lower than the second water level.

The control device 2 is configured to determine that the steam generator 1 needs to be descaled when the first water level detecting device 111 does not obtain the water level information and the second water level detecting device 112 obtains the water level information. Thus, the scale detection logic is simple and easy to implement, while facilitating a simplification of the structure of the steam generation system 100.

According to the steam generation system 100 of the embodiment of the invention, the control device 2 is arranged to determine that the steam generator 1 needs to be descaled when the first water level detection device 111 does not obtain the water level information and the second water level detection device 112 obtains the water level information, so that the automatic detection of the scale of the steam generator 1 can be realized, the automatic determination of whether the steam generator 1 needs to be descaled can be realized, the water level detection assembly 11 arranged in the steam generator 1 can be adopted, and the structure of the steam generation system 100 can be simplified conveniently.

Optionally, the steam generating system 100 is a steam cooking appliance.

In some embodiments of the present invention, as shown in fig. 5, the steam generator 1 further comprises a housing 12, a chamber 120 is defined in the housing 12, the housing 12 is formed with a water inlet 12a and a steam outlet 12b respectively communicated with the chamber 120, a user can add a certain amount of water into the housing 12 through the water inlet 12a, or other components such as a water tank assembly and the like can inject a certain amount of water into the housing 12 through the water inlet 12a, and steam generated by the steam generator 1 can be discharged through the steam outlet 12 b.

As shown in fig. 6 to 8, the steam generator 1 further includes a first partition 13, the first partition 13 is disposed in the housing 12, and the first partition 13 partitions the chamber 120 into a first chamber 120a and a second chamber 120b, a first communication port 13a is formed at an upper portion of the first partition 13, a lower end of the first partition 13 is spaced apart from the bottom wall of the housing 12 such that a second communication port 13b is defined between the lower end of the first partition 13 and the bottom wall of the housing 12, and the first chamber 120a and the second chamber 120b are communicated through the first communication port 13a and the second communication port 13b, so that water in the first chamber 120a may flow to the second chamber 120b through the second communication port 13b, and water in the second chamber 120b may also flow to the first chamber 120a through the second communication port 13b, so that a free water level in the first chamber 120a and a free water level in the second chamber 120b may be at the same level, and similarly, if steam is generated in the first chamber 120a, steam may flow to the first chamber 120b through the first communication port 13a to the second chamber 120 b.

For example, in the example of fig. 6-8, the inlet 12a and the outlet 12b may both be formed on the first chamber 120a or the second chamber 120 b; of course, one of the inlet 12a and the outlet 12b may be formed on the first chamber 120a and the other on the second chamber 120 b.

As shown in fig. 5-7, the steam generator 1 further includes a heating assembly 14, and the heating assembly 14 is used for heating the first chamber 120a, so that the water in the first chamber 120a is heated to become steam, and the high-temperature steam is finally discharged out of the housing 12 through the steam outlet 12 b. Wherein, the water level detection assembly 11 is disposed in the second chamber 120b, and due to the isolation effect of the first partition 13, the boiling degree of the water in the second chamber 120b is lower than that of the water in the first chamber 120a, which is beneficial to avoiding the detection accuracy of the water level detection assembly 11 from being influenced by the fierce boiling of the water in the second chamber 120b, thereby facilitating the guarantee of the accuracy of the scale detection.

It can be understood that, since the heating assembly 14 is used for heating the water in the first chamber 120a, the water in the first chamber 120a is heated more, and the water in the first chamber 120a boils more strongly compared to the second chamber 120b, the first chamber 120a may correspond to a "hot water boiling region", and the second chamber 120b may correspond to a "hot water non-boiling region", and by disposing the water level detecting assembly 11 in the second chamber 120b, the accuracy of water level detection can be ensured.

It should be noted that the water in the second chamber 120b does not necessarily have to boil, but means that the water in the first chamber 120a boils more strongly than the water in the second chamber 120 b.

Alternatively, in the example of fig. 5 to 8, a water discharge port 12c communicating with the chamber 120 is further formed on the housing 12, and water in the housing 12 may be discharged to the outside of the housing 12 through the water discharge port 12 c. For example, a drain port 12c may be formed at the bottom of the chamber 120 to drain all of the water in the housing 12, avoiding the presence of residual water in the housing 12.

Alternatively, the heating assembly 14 may be located outside the housing 12 so that scale does not build up on the heating assembly 14.

In some embodiments, as shown in fig. 6-8, the steam outlet 12b is disposed in the second chamber 120b, so that the steam generated in the first chamber 120a can flow into the second chamber 120b through the first communication port 13a and be discharged out of the housing 12 through the steam outlet 12b, the arrangement of the first partition 13 does not affect the normal discharge of the steam, and meanwhile, when the high-temperature steam encounters the first partition 13, moisture carried by the high-temperature steam can be condensed on the first partition 13, so that excessive water can be prevented from being carried into the second chamber 120b, and then since the water in the second chamber 120b is reduced, the amount of water overflowing from the steam outlet 12b is reduced, thereby further reducing the dryness of the steam sprayed by the steam generator 1, when the steam generating system 100 is a steam cooking appliance, the taste of the food water can be improved, the steam cooking appliance can be conveniently cleaned, and the utilization rate of the steam cooking appliance can be improved.

Alternatively, in the example of fig. 6 to 8, the first partitioning member 13 is vertically arranged, and the first communication port 13a is formed at the upper end of the first partitioning member 13. Of course, the first separator 13 may be arranged obliquely with respect to the vertical direction, and the contact area of the first separator 13 with the high-temperature steam may be increased to some extent, so that more water carried in the high-temperature steam is condensed on the first separator 13.
