Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a steam generating device and a household appliance. Background Art

[0002] At present, the detection of the maximum and minimum water volumes inside the steam generator is mainly implemented in the following ways: using a probe-type water level gauge for the high liquid level and the low liquid level respectively, and determining whether the water level gauge is in contact with the water surface by detecting the resistance or capacitance value of the circuit between the water level gauge and the shell of the steam generating part; when the circuit of the low liquid level gauge is not conductive, the water level in the steam generating part is lower than the designed low liquid level, and when the high liquid level gauge is conductive, the water level in the steam generating part is higher than the designed high liquid level. This setting method requires the use of multiple probe-type water level gauges, and requires an interface to be set on the steam generating part for each water level gauge for installation, fixing and circuit wiring, which increases the processing cost of the steam generating part, increases the difficulty of wiring, and also limits the miniaturization of the steam generating part. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] To this end, a first aspect of the present invention provides a steam generating device.

[0005] A second aspect of the present invention further provides a household appliance.

[0006] In view of this, a first aspect of the present invention proposes a steam generating device, comprising: a steam generating part; a detection component, the detection component comprising a detection member, at least a portion of the detection member extends into the steam generating part, and is used to detect the liquid level in the steam generating part; a float component, comprising a float and a first magnetic member, the first magnetic member is arranged on the float, the float is located between the detection member and the bottom wall of the steam generating part and can float on the liquid, and the first magnetic member is at least arranged opposite to the detection member and can be adsorbed to each other; wherein, when the liquid level in the steam generating part is greater than or equal to the first liquid level, the float is adsorbed to the detection member through the first magnetic member, the detection member contacts the liquid through the float, and the electrical signal of the detection member is a first electrical signal; when the liquid level in the steam generating part is less than or equal to the second liquid level, the float sinks with the liquid and separates from the detection member, and the electrical signal of the detection member is a second electrical signal.

[0007] The steam generating device provided by the present invention comprises a steam generating part, a detection component and a float component. The detection component comprises a detection member, a part of which extends into the steam generating part, the float component comprises a float and a first magnetic member, the float is located between the bottom wall of the steam generating part and the detection member, and the float can float on the liquid, and the first magnetic member is at least arranged opposite to the detection member and can be adsorbed to each other. When the liquid level in the steam generating part is greater than or equal to the first liquid level, the float contacts the detection part, the first magnetic part is attracted to the detection part, the detection part is connected to the shell of the steam generating part through the liquid, so that the electrical signal of the detection part changes, that is, when the liquid level in the steam generating part is greater than or equal to the first liquid level, the electrical signal is the first electrical signal; as the steam generating part is heated, the liquid gradually turns into steam, so that the liquid level in the steam generating part gradually decreases, in the initial stage of the liquid level decrease, since the first magnetic part is attracted to the detection part, the float will not sink as the liquid level decreases, until the liquid level drops to the second liquid level, the sum of the buoyancy and magnetic attraction of the float is less than the weight of the float, the float sinks rapidly and separates from the detection part, and there is air or steam with extremely low electrical conductivity between the detection part and the float, so that the electrical signal of the detection part The signal is the second electrical signal, that is, when the liquid level in the steam generating part is less than or equal to the second liquid level, the electrical signal is the second electrical signal, and then according to the difference in the electrical signals of the detection element, at least the first liquid level and the second liquid level can be detected, that is, the detection of high and low liquid levels is achieved through one detection element, so that the liquid level in the steam generating part can be kept stable, which can effectively avoid the problem of insufficient steam, weakened steam or dry burning in the steam generating part when the water level is too low and the inability to achieve the ironing effect, as well as the problem of too long steam preheating time and spraying water to respond to the ironing effect when the water level is too high. At the same time, this arrangement also reduces the number of detection elements, reduces the circuit wiring cost and the manufacturing cost of the steam generating device, reduces the occupation of the internal space of the steam generating part by the detection element, and is conducive to the miniaturized design of the steam generating part.

[0008] The steam generating device provided by the present invention may also have the following additional technical features:

[0009] In some embodiments, optionally, the float assembly also includes: a second magnetic component, which is arranged on the bottom wall of the steam generating part, and a first magnetic component is arranged at opposite ends of the float and is respectively arranged opposite to the detection component and the second magnetic component; when the liquid level in the steam generating part is less than or equal to the second liquid level, the float sinks with the liquid to separate from the detection component, and the first magnetic component is adsorbed with the second magnetic component; when the liquid level in the steam generating part is greater than or equal to the first liquid level, the first magnetic component is separated from the second magnetic component.

[0010] In this embodiment, the first magnetic member is respectively disposed at two opposite ends of the float, the float assembly further comprises a second magnetic member, the second magnetic member is disposed on the bottom wall of the steam generating portion, and the first magnetic members at both ends of the float are respectively disposed opposite to the detection member and the second magnetic member. Specifically, the first magnetic member at the upper end of the float is disposed opposite to the detection member and is used to be adsorbed with the detection member, and the first magnetic member at the lower end of the float is disposed opposite to the second magnetic member and is used to be adsorbed with the second magnetic member. When the liquid level in the steam generating part is lower than the second liquid level, the float is attracted to the second magnetic part through the first magnetic part at the lower end, and the float and the detection part are arranged at a distance, so that the detection part and the shell of the steam generating part are isolated by steam or air, and the electrical signal of the detection part is the second electrical signal. As the liquid level rises, the depth of the float immersed in the liquid gradually increases, but in the early stage of the liquid level increase, due to the action of the magnetic attraction between the first magnetic part and the second magnetic part, the float will not rise directly with the liquid until the buoyancy of the float is greater than or equal to the sum of the gravity of the float and the magnetic attraction generated by the second magnetic part on the float. As the liquid level continues to rise, the float floats up with the liquid level, and the magnetic attraction between the first magnetic part and the second magnetic part at the bottom of the float gradually decreases to zero as the distance between the two increases. Due to the disappearance of the magnetic attraction, the float quickly floats up to contact with the detection part. At this time, the liquid level reaches the first liquid level, and the detection part is connected to the shell of the steam generating part through the liquid. Correspondingly, when the liquid level in the steam generating part gradually decreases, due to the adsorption effect between the first magnetic part at the upper end of the float and the detection part, the float will not drop as the liquid level drops. Therefore, the control part still determines that the water level is high at this time and will not control the liquid replenishment. As the liquid level drops, the volume of the float immersed in the liquid gradually decreases, so that the buoyancy it receives also gradually decreases, until the sum of the buoyancy received by the float and the magnetic attraction between the detection part and the first magnetic part is equal to the gravity of the float. As the liquid level further decreases, the float sinks rapidly and separates from the detection part, and the distance between the float and the detection part gradually increases. The magnetic attraction between the two disappears rapidly as the distance between the two increases, so that the distance between the float and the second magnetic part gradually decreases, and the float and the second magnetic part are adsorbed again.

[0011] In some embodiments, optionally, the detection component further includes: a third magnetic component, which is disposed at one end of the detection component close to the float, and the third magnetic component is used to be adsorbed with the first magnetic component.

[0012] In this embodiment, the detection assembly further includes a third magnetic component, which is disposed at one end of the detection component close to the float, so that the detection component can be adsorbed by the first magnetic component on the upper portion of the float through the third magnetic component.

[0013] In some embodiments, optionally, the steam generating device also includes: a pump body, the steam generating part also includes a liquid inlet, the pump body is connected to the liquid inlet, and is used to transport liquid into the steam generating part; a control part, connected to the pump body, and is used to control the pump body to transport liquid into the steam generating part when the electrical signal is a second electrical signal, and to control the pump body to close when the electrical signal is a first electrical signal.

[0014] In this embodiment, the steam generating device further includes a pump body and a control unit, and the control unit is capable of controlling the pump body to transport liquid into the steam generating unit. When the liquid level in the steam generating unit is less than or equal to the second liquid level, the electrical signal is the second electrical signal, and the control unit determines that the liquid level in the steam generating unit is a low liquid level, and then controls the pump body to pump liquid into the steam generating unit. As the liquid level in the steam generating unit rises, when the float contacts the detection element, the detection element is connected to the shell of the steam generating unit through the float, the liquid, and the electrical signal of the detection element detected is the first electrical signal, and then the control unit determines that the liquid level reaches the first liquid level, and controls the pump body to stop pumping liquid into the steam generating unit. Correspondingly, as the product is used, the liquid level gradually decreases. Due to the adsorption effect between the first magnetic part and the detection part, in the initial stage of the liquid level drop, the float will not sink as the liquid level drops, and the control unit will still determine that the liquid level is a high level and will not control the pump body to pump liquid. Until the liquid level drops to the second level, the float will sink rapidly and separate from the detection part. There is air or steam with extremely low conductivity between the detection part and the float. The electrical signal detected by the detection part is the second electrical signal, and the control unit will control the pump body to replenish liquid again. This reciprocating cycle can ensure that the liquid level in the steam generating part always remains stable.

[0015] In some embodiments, optionally, the float assembly further includes: a bracket, which is disposed in the steam generating part and communicated with the steam generating part, and the float is disposed in the bracket and can float with the liquid in the bracket.

Optionally, the connection seat is connected to the top wall of the steam generating part in a variety of ways, such as bonding, clamping or threaded connection.

[0021] In some embodiments, optionally, the top wall of the steam generating portion is provided with an opening, the connecting seat is provided at the opening, and a portion of the detecting member extends into the steam generating portion through the opening.

[0022] In this embodiment, the top wall of the steam generating part is provided with an opening, and the connecting seat is connected to the steam generating part through the opening, so that the installation of the detection component is more convenient.

DETAILED DESCRIPTION

[0059] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0060] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0061] Refer to the following Figures 1 to 17 A steam generating device and a household appliance according to some embodiments of the present invention are described.

[0062] like Figure 1 , Figure 2 and Figure 3 As shown, according to one embodiment of the present invention, the present invention provides a steam generating device, comprising: a steam generating part 1 , a detection component 2 and a float component 3 .

[0063] Specifically, Figures 4 to 9 As shown, the detection component 2 includes a detection member 20, at least a portion of which extends into the steam generating part 1 and is used to detect the liquid level in the steam generating part 1; the float component 3 includes a float 30 and a first magnetic member 32, the first magnetic member 32 is arranged on the float 30, the float 30 is located between the detection member 20 and the bottom wall of the steam generating part 1 and can float on the liquid, and the first magnetic member 32 is at least arranged opposite to the detection member 20 and can be adsorbed; wherein, when the liquid level in the steam generating part 1 is greater than or equal to the first liquid level A, the float 30 is adsorbed on the detection member 20 through the first magnetic member 32, the detection member 20 contacts with the liquid through the float 30, and the electrical signal of the detection member 20 is a first electrical signal; when the liquid level in the steam generating part 1 is less than or equal to the second liquid level B, the float 30 sinks with the liquid and separates from the detection member 20, and the electrical signal of the detection member 20 is a second electrical signal.

[0064] The steam generating device provided by the present invention comprises a steam generating part 1, a detection component 2 and a float component 3. The detection component 2 comprises a detection member 20, a part of which extends into the steam generating part 1, and the float component 3 comprises a float 30 and a first magnetic member 32. The float 30 is located between the bottom wall of the steam generating part 1 and the detection component 20, and the float 30 can float on the liquid. The first magnetic member 32 is at least arranged opposite to the detection member 20 and can be attracted to each other. Figures 4 to 9 As shown, when the liquid level in the steam generating part 1 is greater than or equal to the first liquid level A, the float 30 contacts the detection member 20, the first magnetic member 32 is attracted to the detection member 20, and the detection member 20 is connected to the shell of the steam generating part 1 through the liquid, so that the electrical signal of the detection member 20 changes, that is, when the liquid level in the steam generating part 1 is greater than or equal to the first liquid level A, the electrical signal is the first electrical signal; as the steam generating part 1 is heated, the liquid gradually turns into steam, so that the liquid level in the steam generating part 1 gradually decreases. In the early stage of the liquid level decrease, since the first magnetic member 32 is attracted to the detection member 20, the float 30 will not sink as the liquid level decreases. Until the liquid level drops to the second liquid level B, the sum of the buoyancy and magnetic attraction on the float 30 is less than the gravity of the float 30. The float 30 sinks rapidly and separates from the detection member 20. There is air or steam with extremely low conductivity between the detection member 20 and the float 30, so that the electrical signal of the detection member 20 is the second electrical signal, that is, when the liquid level in the steam generating part 1 is less than or equal to the second liquid level B, the electrical signal is the second electrical signal, and then according to the difference in the electrical signal of the detection member 20, at least the first liquid level A and the second liquid level B can be detected, that is, the detection of high and low liquid levels is achieved through one detection member 20, the number of detection members 20, the circuit wiring cost, and the manufacturing cost of the steam generating device are reduced, so that the liquid level in the steam generating part 1 can be kept stable, and the problems of interruption of the steam volume in the steam generating part 1 and dry burning when the water level is too low, and the problem of too long steam preheating time and water spraying when the water level is too high can be effectively avoided.

[0065] It is understandable that the first electrical signal is different from the second electrical signal. Optionally, the electrical signal includes a resistance value or a capacitance value or a capacitor charge and discharge waveform, or may be other electrical signals that change with changes in conductivity or distance between two conductors.

[0066] It is understandable that the first liquid level A is higher than the second liquid level B, and at least a portion of the detection member 20 is a magnetically attractive structure or a magnetically attractive structure is provided on the detection member 20 so that the first magnetic member 32 on the float 30 can be adsorbed to the detection member 20 .

[0067] It can be understood that when the liquid level in the steam generating part 1 is the first liquid level A, there is a gap between the float 30 and the bottom wall of the steam generating part 1, and when the liquid level in the steam generating part 1 is the second liquid level B, there is a gap between the float 30 and the detection part 20, and the two gaps are the same.

[0068] Optionally, when the electrical signal is a resistance value, the first electrical signal is a first parameter value, the second electrical signal is a second parameter value, the first parameter value is less than the second parameter value, and when the electrical parameter value of the detection component 20 is greater than or equal to the second parameter value, the control unit 5 can determine that the liquid level in the steam generating part 1 is less than or equal to the second liquid level B, and then control the steam generating part 1 to replenish the liquid. As the liquid level rises, the float 30 gradually rises until the float 30 contacts the detection component 20, and the electrical parameter value of the detection component 20 is less than or equal to the first parameter value, it is determined that the liquid level is greater than or equal to the first liquid level A, and the liquid supply to the steam generating part 1 is stopped.

[0069] Optionally, when the electrical signal is a charging and discharging waveform of a capacitor, the first electrical signal is a first waveform, the second electrical signal is a second waveform, and the first waveform is different from the second waveform. When the detected waveform of the detection element 20 is the second waveform, the control unit 5 can determine that the liquid level in the steam generating part 1 is less than or equal to the second liquid level B, and then control the steam generating part 1 to replenish liquid. As the liquid level rises, the float 30 gradually rises until the float 30 contacts the detection element 20. The detected waveform of the detection element 20 is the first waveform, and it is determined that the liquid level is greater than or equal to the first liquid level A, and the supply of liquid to the steam generating part 1 is stopped.

[0070] like Figures 4 to 9 As shown, in some embodiments, optionally, the float assembly 3 also includes: a second magnetic member 34, which is arranged on the bottom wall of the steam generating part 1, and the first magnetic member 32 is arranged at two opposite ends of the float 30 and is respectively arranged opposite to the detection member 20 and the second magnetic member 34; when the liquid level in the steam generating part 1 is less than or equal to the second liquid level B, the float 30 sinks with the liquid to separate from the detection member 20, and the first magnetic member 32 is adsorbed with the second magnetic member 34; when the liquid level in the steam generating part 1 is greater than or equal to the first liquid level A, the first magnetic member 32 is separated from the second magnetic member 34.

[0071] In this embodiment, if Fig.12 , Fig.13 and Fig.14 As shown, the first magnetic member 32 is respectively disposed at the two opposite ends of the float 30, and the float assembly 3 further includes a second magnetic member 34, which is disposed on the bottom wall of the steam generating part 1, and the first magnetic members 32 at the two ends of the float 30 are respectively disposed opposite to the detection member 20 and the second magnetic member 34. Specifically, the first magnetic member 32 at the upper end of the float 30 is disposed opposite to the detection member 20 and is used to be adsorbed with the detection member 20, and the first magnetic member 32 at the lower end of the float 30 is disposed opposite to the second magnetic member 34 and is used to be adsorbed with the second magnetic member 34. Figure 4As shown, when the liquid level in the steam generating part 1 is lower than the second liquid level B, the float 30 is attracted to the second magnetic part 34 through the first magnetic part 32 at the lower end, and the float 30 and the detection part 20 are spaced apart, so that the detection part 20 and the shell of the steam generating part 1 are isolated by steam or air, and the electrical signal of the detection part 20 is the second electrical signal, as shown in FIG. Figure 5 As shown, as the liquid level rises, the depth of the float 30 immersed in the liquid gradually increases. However, in the early stage of the liquid level increase, due to the magnetic attraction between the first magnetic member 32 and the second magnetic member 34, the float 30 will not rise directly with the liquid until the buoyancy of the float 30 is greater than or equal to the sum of the gravity of the float 30 and the magnetic attraction generated by the second magnetic member 34 on the float 30. As the liquid level further rises, the float 30 floats up with the liquid level, and the magnetic attraction between the first magnetic member 32 and the second magnetic member 34 at the bottom of the float 30 gradually decreases to zero as the distance between the two increases. Due to the disappearance of the magnetic attraction, the float 30 quickly floats up to contact with the detection member 20. At this time, the liquid level reaches the first liquid level A (as shown in FIG. 1 ). Figure 6 and Figure 7 As shown), the detection member 20 is connected to the shell of the steam generating part 1 through the liquid. Figure 8 and Fig. 9 As shown in FIG. 1 , when the liquid level in the steam generating part 1 gradually decreases, due to the adsorption effect between the first magnetic member 32 at the upper end of the float 30 and the detection member 20, the float 30 will not drop as the liquid level decreases. Therefore, the control unit 5 still determines that the water level is high and will not control the liquid replenishment. As the liquid level decreases, the volume of the float 30 immersed in the liquid gradually decreases, so that the buoyancy it receives also gradually decreases, until the sum of the buoyancy received by the float 30 and the magnetic attraction between the detection member 20 and the first magnetic member 32 is equal to the weight of the float 30. Figure 4 As shown, as the liquid level further decreases, the float 30 sinks rapidly and separates from the detection member 20, and the distance between the float 30 and the detection member 20 gradually increases. The magnetic attraction between the two disappears rapidly as the distance between the two increases, so that the distance between the float 30 and the second magnetic member 34 gradually decreases, and the float 30 and the second magnetic member 34 are adsorbed again.

[0072] Understandably, Figures 4 to 9 The dashed line in shows the liquid level.

[0073] In specific applications, such as Figure 4As shown in FIG. 1 , when the liquid level in the steam generating part 1 is at the second liquid level B, the depth of the float 30 immersed in the water is X1, the corresponding buoyancy of the water is equal to the gravity of the float 30, the distance between the first magnetic member 32 and the second magnetic member 34 at the bottom of the float 30 is very small, and the second magnetic member 34 adsorbs the float 30 on the second magnetic member 34 through magnetic attraction. At this time, the distance between the detection member 20 and the float 30 is Y, and there is air or steam with extremely low conductivity between the detection member 20 and the float 30. The detection member 20 and the shell of the steam generating part 1 are close to each other. When the loop resistance value or capacitance value between the two bodies is a high value, the control circuit will determine that the water level in the steam generating part 1 is a low water level, thereby triggering the action of replenishing water in the steam generating part 1; then the liquid level in the steam generating part 1 will gradually increase from the second liquid level B, but due to the magnetic attraction of the second magnetic member 34 to the float 30, the float 30 will still be adsorbed on the second magnetic member 34 at the initial stage of the liquid level increase. As the liquid level gradually increases, the volume of the float 30 immersed below the water surface increases, resulting in a gradual increase in the buoyancy it receives. Figure 5 As shown, until the buoyancy is equal to the sum of the gravity of the float 30 and the magnetic attraction of the second magnetic member 34 to the float 30, the float 30 is immersed in the water to a depth of X2, and X2 is designed to be greater than Y. Figure 6 and Figure 7 As shown, when the water level further rises to the first liquid level A, during this process, the float 30 will float up with the rise of the liquid level, and the magnetic attraction between the second magnetic member 34 and the first magnetic member 32 at the bottom of the float 30 will rapidly decrease to zero as the distance between the two increases. Due to the disappearance of the magnetic attraction, the float 30 will rapidly float up to contact with the detection member 20. After the first magnetic member 32 at the top of the float 30 contacts the detection member 20, a magnetic attraction will be generated to adsorb the float 30 on the detection member 20; at this time, the detection member 20, the float 30 and the shell of the steam generating part 1 will be connected through the liquid, the resistance value or capacitance value between the detection member 20 and the shell of the steam generating part 1 will be significantly reduced, and the control circuit will determine that the water level in the steam generating part 1 is a high water level, thereby stopping the replenishment of water into the steam generating part 1. Then, as the product is used, the water level in the steam generating part 1 will gradually drop from the first liquid level A. However, due to the effect of the magnetic attraction of the detection member 20 on the float 30, in the initial stage of the liquid level drop, since the float 30 is immersed in the water at a greater depth, the buoyancy it is subjected to is greater, and the buoyancy and magnetic attraction exerted on the float 30 are greater than the gravity of the float 30. Therefore, the float 30 will be adsorbed on the detection member 20, and the detection member 20, the float 30 and the shell of the steam generating part 1 will remain conductive through the water, and the control circuit will determine that the water level in the steam generating part 1 is a high water level. Furthermore, as the liquid level in the steam generating part 1 drops, the depth of the float 30 immersed in the water will decrease, so that the buoyancy exerted on the float 30 will gradually decrease, such as Figure 8As shown in FIG. 1 , when the float 30 is immersed in water to a depth of X3, the sum of the buoyancy of the float 30 and the magnetic attraction of the detection member 20 to the float 30 is equal to the gravity of the float 30. Furthermore, by designing the density of the float 30 or the magnetic attraction strength of the first magnetic member 32 at the top of the float 30 or the first magnetic member 32 at the bottom of the float 30, X1=X3+Y. Thereafter, as shown in FIG. Fig. 9 As shown, if the liquid level further drops, the float 30 will move downward with the drop of the liquid level, and the distance between the first magnetic member 32 at the top of the float 30 and the detection member 20 will increase. At this time, there is air or steam with extremely low conductivity between the detection member 20 and the float 30, and the loop resistance or capacitance between the detection member 20 and the shell of the steam generating part 1 is high. The control circuit will judge that the water level in the boiler is a low water level; at the same time, the magnetic attraction between the first magnetic member 32 at the top of the float 30 and the detection member 20 will disappear rapidly as the distance between the two increases, causing the float 30 to sink rapidly and contact the second magnetic member 34 fixed at the bottom of the steam generating part 1, thereby being subjected to the magnetic attraction of the second magnetic member 34. Therefore, the present application can realize the high and low water level judgment of the water level in the steam generating part 1 being the high water level of the first liquid level A and the low water level of the second liquid level B, so that the water level inside the steam generating part 1 can be kept stable by triggering the pump body 4 to replenish water to the high water level at the low water level.

[0074] It is understandable that when the liquid level in the steam generating part 1 is the first liquid level A, the gap between the float 30 and the second magnetic member 34 is the same as the gap between the float 30 and the detection member 20 when the liquid level is the second liquid level B.

[0075] like Fig.10 and Fig.11 As shown, in some embodiments, optionally, the detection component 2 further includes: a third magnetic member 22 , which is disposed at one end of the detection member 20 close to the float 30 , and the third magnetic member 22 is used to be adsorbed with the first magnetic member 32 .

[0076] In this embodiment, the detection component 2 further includes a third magnetic member 22 , which is disposed at one end of the detection member 20 close to the float 30 , so that the detection member 20 can be adsorbed by the first magnetic member 32 on the upper portion of the float 30 through the third magnetic member 22 .

[0077] Optionally, among the first magnetic part 32 at the top of the float 30, the first magnetic part 32 at the bottom of the float 30, the second magnetic part 34 and the third magnetic part 22, one of the two magnetic structures that can be attracted to each other is a permanent magnet and the other is a ferromagnetic part, or both are permanent magnets that can be attracted to each other.

[0078] like Fig.15As shown, in some embodiments, optionally, the steam generating device further includes: a pump body 4, the steam generating part 1 further includes a liquid inlet 10, the pump body 4 is connected to the liquid inlet 10, and is used to transport liquid into the steam generating part 1; a control part 5, connected to the pump body 4, and is used to control the pump body 4 to transport liquid into the steam generating part 1 when the electrical signal is the second electrical signal, and to control the pump body 4 to close when the electrical signal is the first electrical signal.

[0079] In this embodiment, the steam generating device further includes a pump body 4 and a control unit 5, and the control unit 5 can control the pump body 4 to transport liquid into the steam generating unit 1. When the liquid level in the steam generating unit 1 is less than or equal to the second liquid level B, the electrical signal is a second electrical signal, and the control unit 5 determines that the liquid level in the steam generating unit 1 is a low liquid level, and then controls the pump body 4 to pump liquid into the steam generating unit 1. As the liquid level in the steam generating unit 1 rises, when the float 30 contacts the detection member 20, the detection member 20 is connected to the shell of the steam generating unit 1 through the float 30, the liquid, and the electrical signal of the detection member 20 is a first electrical signal, and then the control unit 5 determines that the liquid level reaches the first liquid level A, and controls the pump body 4 to stop pumping liquid into the steam generating unit 1. Correspondingly, as the product is used, the liquid level gradually decreases. Due to the adsorption effect between the first magnetic member 32 and the detection member 20, in the initial stage of the liquid level decrease, the float 30 will not sink as the liquid level decreases, and the control unit 5 still determines that the liquid level is a high level and will not control the pump body 4 to pump liquid. Until the liquid level drops to the second liquid level B, the float 30 sinks rapidly and separates from the detection member 20. There is air or steam with extremely low conductivity between the detection member 20 and the float 30. The electrical signal detected by the detection member 20 is the second electrical signal, and the control unit 5 controls the pump body 4 to replenish liquid again. This reciprocating cycle can ensure that the liquid level in the steam generating part 1 always remains stable.

[0080] like Figure 2 As shown, in some embodiments, optionally, the float assembly 3 further includes: a bracket 36 disposed in the steam generating part 1 and connected to the steam generating part 1 , and the float 30 is disposed in the bracket 36 and can float with the liquid in the bracket 36 .

[0091] In some embodiments, optionally, the float 30 is a conductive member; and / or the detection member 20 includes a liquid level probe; and / or Fig.12 , Fig.13 and Fig.14 As shown, the float assembly 3 further includes a base 39 and a cover 38 . The cover 38 and the base 39 are disposed at opposite ends of the float 30 . The base 39 and the cover 38 are the first magnetic member 32 .

[0092] In this embodiment, the float 30 is a conductive member, and the detection member 20 can contact the liquid through the float 30, so that the detection member 20 forms a loop with the shell of the steam generating part 1 under the first liquid level A. The detection member 20 includes a liquid level probe, which reduces the space occupied in the steam generating part 1 and realizes the detection of high and low liquid levels. The float assembly 3 also includes a base 39 and a cover 38. The base 39 and the cover 38 constitute the float assembly 3 with the float 30. The cover 38 and the base 39 are arranged at opposite ends of the float 30. The base 39 and the cover 38 are the first magnetic member 32, which are respectively used to adsorb with the second magnetic member 34 or the detection member 20.

[0093] Optionally, the base 39 and the cover 38 are respectively embedded in two ends of the float 30 .

[0094] like Figures 1 to 3 As shown, in some embodiments, optionally, the steam generating device further includes: a valve body 6 , the steam generating part 1 further includes an exhaust port 14 , the exhaust port 14 is used to discharge steam, and the valve body 6 is disposed at the exhaust port 14 for opening or closing the exhaust port 14 .

[0095] In this embodiment, a valve body 6 is provided at the exhaust port 14 of the steam generating part 1 to achieve the discharge of steam as required.

[0096] According to one embodiment of the present invention, a household appliance is further provided, comprising: a steam generating device as provided in any of the above embodiments.

[0097] The household appliance provided by the present invention comprises the steam generating device provided in any one of the above embodiments and therefore has all the beneficial effects of the steam generating device.

[0098] In some embodiments, optionally, the household appliance is any one of a hanging iron, a steamer, and a steam-bake-in-one machine.

[0099] In this embodiment, the household appliance is a clothes processor, such as a hanging iron, and the household appliance may also be a cooking appliance such as a steamer, a steam-bake-in-one machine, etc.

[0100] like Fig.16 and Fig.17 As shown, in some embodiments, optionally, when the household appliance is a garment steamer, the garment steamer further includes: a main unit 100, in which a steam generating unit 1 is disposed; an ironing component 7, which is disposed in the main unit 100 and is connected to the steam generating unit 1, and the steam generating unit 1 can deliver steam to the ironing component 7; and a water tank component 8, which is disposed in the main unit 100 and is connected to the steam generating unit 1, and is used to deliver liquid to the steam generating unit 1.

[0101] In this embodiment, when the household appliance is a garment steamer, the garment steamer further includes a host 100, an ironing assembly 7 and a water tank assembly 8. The steam generating part 1 is arranged in the host 100, and the ironing assembly 7 is connected to the steam generating part 1, so that the steam generated by the steam generating part 1 can be transported to the ironing assembly 7, and then the clothes are ironed by the ironing assembly 7. At the same time, the water tank assembly 8 is connected to the steam generating part 1, and is used to transport liquid into the steam generating part 1, so that the steam generating part 1 can continuously output steam. The hanging iron proposed in the present application realizes the detection of high and low liquid levels through the cooperation of the detection component 2 and the float component 3, so that the liquid level in the steam generating part 1 can be kept stable, which can effectively avoid the problem of insufficient steam, weakened steam or dry burning in the steam generating part 1 when the water level is too low and unable to generate sufficient steam, thereby avoiding the problem of weak steam output of the ironing component 7 and unable to achieve the ironing effect, and avoiding the problem of too long steam preheating time and water spraying when the water level is too high, thereby making the steam output of the ironing component 7 continuous and stable to ensure the ironing effect.

[0102] In some embodiments, optionally, the main unit 100 includes: a back panel 102; an enclosure 104, which is arranged on one side of the back panel 102 and encloses an installation cavity 106 together with the back panel 102, the steam generating part 1 is arranged in the installation cavity 106, and the top of the enclosure 104 is recessed into the installation cavity 106 to form a first installation groove 1040 and a second installation groove 1042, the first installation groove 1040 and the second installation groove 1042 are arranged side by side relative to the back panel 102, the ironing component 7 is arranged in the first installation groove 1040, and the water tank component 8 is arranged in the second installation groove 1042.

[0103] In this embodiment, the main unit 100 includes a back panel 102 and a surrounding panel 104. The surrounding panel 104 is arranged on one side of the back panel 102 and together with the back panel 102, forms an installation cavity 106. The steam generating part 1 is arranged in the installation cavity 106, thereby protecting the steam generating part 1 and preventing the user from being scalded by the high temperature of the steam generating part 1 when it is working. The top of the enclosure 104 is recessed into the mounting cavity 106 to form a first mounting groove 1040 and a second mounting groove 1042. The ironing component 7 is disposed in the first mounting groove 1040, and the water tank component 8 is disposed in the second mounting groove 1042. On the one hand, this arrangement enables the ironing component 7 and the water tank component 8 to be disposed on the same side of the back plate 102, so that the garment steamer is flat as a whole, thereby facilitating the storage of the garment steamer. On the other hand, this arrangement enables the water tank component 8 and the ironing component 7 to be located at the top of the enclosure 104, thereby facilitating the removal and placement of the ironing component 7 and the water tank component 8. As for the water tank component 8, the water replenishing operation can be performed on the water tank component 8 without lifting the water tank component 8, thereby making the use of the garment steamer more convenient.

[0104] In some embodiments, optionally, the garment steamer further includes: a pump body, disposed in the installation cavity 106 and connected between the water tank assembly 8 and the steam generating part 1; and / or a filter 9, disposed at the bottom of the water tank assembly 8 and connected to the water tank assembly 8.

[0105] In this embodiment, the garment steamer further includes a pump body, which is connected between the water tank assembly 8 and the steam generating part 1, and is used to transport liquid into the steam generating part 1 to achieve continuous output of steam. The garment steamer further includes a filter 9, which is arranged at the bottom of the water tank assembly 8 and is connected to the water tank assembly 8, and further filters the liquid transported from the water tank assembly 8 to the steam generating part 1.

[0106] Optionally, a filter 9 is connected between the water tank assembly 8 and the pump body.

[0107] In a specific application, the steam boiler (e.g., the steam generating part 1) can be electrically heated to vaporize the water in the boiler to produce steam. The steam boiler is provided with a boiler water inlet (e.g., a liquid inlet 10), and water can flow into the steam boiler through the boiler water inlet to replenish the water in the steam boiler. The steam release valve (e.g., the valve body 6) is sealed and connected to the interface of the steam boiler by means of threads, sealing rings or glue. When the steam release valve is opened, steam output from the steam boiler can be achieved.

[0108] As attached Fig.11 and attached Fig.12 The water level meter (such as the detection component 2) is composed of a probe body (such as the detection part 20), a probe mounting seat (such as the connecting seat 26), a probe cover (such as the insulating cover 24), and a probe magnetic head (such as the third magnetic part); wherein the probe body and the probe magnetic head are assembled into one by welding or the like, and both the probe body and the probe magnetic head are made of conductive materials, and the probe magnetic head is made of magnetic materials; the probe cover is made of insulating material, the probe cover is sleeved and fixed on the outside of the probe body, and the probe body and the probe cover need to be designed to be sealed and waterproof; the probe mounting seat is sleeved and fixed on the outside of the probe cover, and the probe mounting seat and the probe cover need to be designed to be sealed and waterproof; the probe mounting seat of the water level meter is sealed and connected to the upper interface (such as the opening 12) of the steam boiler through waterproof means such as threads, sealing rings or glue.

[0109] The float bracket (such as the bracket 36) and the magnetic block (such as the second magnetic member 34) are fixed to the bottom of the steam boiler by screws or welding, and the magnetic block is made of magnetic material; the float 30 is placed in the float bracket; the float 30 is composed of a float top plug (such as the cover 38), a float body and a float base (such as the base 39), all of which are made of conductive materials, wherein the float top plug and the float base are made of materials that can be attracted by a magnet, i.e., ferromagnetic. In addition, the overall density of the float 30 can be conveniently adjusted by selecting floats of different density materials; under the combined action of the buoyancy of water, the probe magnetic head and the magnetic block, the float 30 will move up and down in the float bracket as the water level changes, thereby realizing the detection of high and low water levels.

[0110] The specific working process of this program is as follows:

[0111] In the product, the control circuit will continuously detect the resistance or capacitance value between the water level gauge and the shell of the steam boiler; Figure 4 As shown, when the water level in the steam boiler is the second liquid level B, the depth of the float 30 immersed in the water is X1, the corresponding buoyancy of the water is equal to the gravity of the float 30, the distance between the float base of the float 30 and the magnetic block is very small, and the magnetic block adsorbs the float 30 on the magnetic block through magnetic attraction. At this time, the distance between the water level probe and the float 30 is Y, and there is air or steam with extremely low conductivity between the water level probe and the float 30. The loop resistance value or capacitance value between the water level gauge and the shell of the steam boiler is a high value (for example, greater than or equal to the second electrical parameter value), and the control circuit will The water level in the boiler is judged to be low, thereby triggering the action of replenishing water to the boiler; then the liquid level in the steam boiler will gradually rise from the second liquid level B, but due to the existence of the magnetic attraction of the magnetic block on the float 30, the float 30 will still be adsorbed on the magnetic block in the early stage of the liquid level rise. As the liquid level gradually rises, the volume of the float 30 immersed below the water surface increases, causing the buoyancy it receives to gradually increase until the buoyancy is equal to the sum of the weight of the float 30 and the magnetic attraction of the magnetic block on the float 30. At this time, the depth of the float 30 immersed in the water is X2, and X2 is designed to be greater than Y (such as Figure 5 As shown), Figure 5 and Figure 6 As shown in FIG. 1 , when the water level further rises to the first liquid level A, during this process, the float 30 will float up with the rise of the water level, and the magnetic attraction between the magnetic block and the float base of the float 30 will rapidly decrease to zero as the distance between the two increases. Due to the disappearance of the magnetic attraction, the float 30 will rapidly float up to contact with the magnetic head of the probe of the water level gauge (as shown in FIG. 1 ). Figure 7As shown in the figure, after the float top plug of the float 30 contacts the probe magnetic head of the water level gauge, a magnetic attraction will be generated to make the float top plug adsorbed on the probe magnetic head of the water level gauge; at this time, the water level gauge, the float 30 and the shell of the steam boiler will be connected through water, and the resistance value or capacitance value between the water level gauge and the shell of the steam boiler will be significantly reduced (for example, less than or equal to the first electrical parameter value), and the control circuit will determine that the water level in the boiler is a high water level and thus stop replenishing water to the boiler; then, as shown in the figure, Figures 7 to 9 As shown, with the use of the product, the water level of the steam boiler will gradually drop from the first liquid level A. However, due to the effect of the magnetic attraction of the probe magnetic head on the float 30, in the initial stage of the liquid level drop, since the float 30 is immersed in the water at a greater depth, the buoyancy it is subjected to is greater, and the buoyancy and magnetic attraction the float 30 is subjected to are greater than the gravity of the float 30. Therefore, the float 30 will be adsorbed on the probe magnetic head of the water level gauge, and the water level gauge, the float 30 and the shell of the steam boiler will remain conductive through the water, and the control circuit will determine that the water level in the boiler is a high water level; further, as the boiler liquid level drops, the depth of the float 30 immersed in the water will decrease, so that the buoyancy the float 30 is subjected to will gradually decrease, as shown in FIG. Figure 8 As shown, when the float 30 is immersed in water to a depth of X3, the sum of the buoyancy of the float 30 and the magnetic attraction of the probe magnetic head to the float 30 is equal to the gravity of the float 30. Further, by designing the density of the float 30 or the magnetic attraction strength between the float top plug and the float base, X1=X3+Y; thereafter, if the liquid level drops further, the float 30 will move downward with the drop in the liquid level, and the distance between the float top plug of the float 30 and the probe magnetic head will increase. At this time, there is air or steam with extremely low conductivity between the water level probe and the float 30, and the loop resistance or capacitance between the water level gauge and the shell of the steam boiler is high, and the control circuit will judge that the water level in the boiler is low; at the same time, the magnetic attraction between the float top plug and the probe magnetic head will disappear rapidly as the distance between the two increases, causing the float 30 to sink rapidly and contact with the magnetic block fixed at the bottom of the steam boiler, thereby being subjected to the magnetic attraction of the magnetic block as shown in the figure. Figure 4 Therefore, the present application can realize the high and low water level judgment of the water level in the steam boiler being a high water level of the first liquid level A and a low water level of the second liquid level B, so that the internal water level of the steam boiler can be kept stable at all times by triggering a water pump (such as the pump body 4) to replenish water to a high water level when the water level is low.

[0112] The present application sets a detection component 2, a float component 3 and a magnetic block, and utilizes buoyancy and magnetic attraction to determine the high water level and the low water level inside the steam boiler, thereby controlling the start and stop of the water pump to replenish water, so that the water level inside the steam boiler is maintained within the design range, which can effectively avoid the interruption of steam volume and dry burning of the steam boiler when the water level is too low, and the problem of long steam preheating time and water spraying when the water level is too high, thereby effectively improving the steam quality and stability of the steam; at the same time, the present application only uses one water level gauge to detect high and low water levels, which can reduce the number of interfaces of the boiler, reduce the volume of the boiler, reduce the number of circuit wiring, and reduce costs.
