Example 1
The invention provides a steam generator of a clothes care device, which comprises a generator body 1 arranged in the clothes care device, wherein the generator body 1 comprises a shell 10 and a heating component arranged in a cavity of the shell 10, the shell 10 is provided with a cavity for containing liquid water, the heating component is used for heating water in the shell 10, the shell 10 is provided with a water inlet 11 and a steam outlet 12,
A plate-shaped structure is further arranged between the steam outlet 12 and the heating component, wherein the plate-shaped structure is provided with a channel for steam to pass through, namely, the steam outlet 12, the plate-shaped structure and the heating component are sequentially arranged from top to bottom, so that mixed air flow formed by heating of the heating component is firstly contacted with the plate-shaped structure to separate the mixed air flow in the flowing process of the mixed air flow towards the steam outlet 12, then the mixed air flow continuously flows towards the steam outlet 12 through the channel until the steam which does not contain liquid water molecules or contains a lower amount of liquid water molecules is provided outwards through the steam outlet 12, the plate-shaped structure is a metal piece, the metal piece has heat conducting performance, when the mixed air flow contacts the plate-shaped structure, heat of the liquid water molecules is conducted through the plate-shaped structure, the liquid water molecules are condensed on the plate-shaped structure due to heat reduction, and the metal piece is not easy to deform and damage, so that the transportation of the clothes treatment device is facilitated. Further, the plate-shaped structure is a stainless steel plate-shaped structure, the heat conductivity coefficient of the stainless steel is low, the condensation of liquid water molecules is ensured, and the excessive rapid loss of the temperature after being heated by the heating component and transmitted from the steam outlet 12 is avoided;
The liquid water enters the cavity of the shell 10 from the water inlet 11, the heating assembly heats the liquid water to form a mixed air flow of liquid water molecules and gaseous water molecules in an evaporated state, usually the volatile matter formed by heating the water is not completely gaseous water (namely gaseous water molecules), the liquid water molecules are mixed, the mixed air flow is a mixture of the liquid water molecules and the gaseous water, the mixed air flow upwards flows to contact with the plate-shaped structure, after the heat of the liquid water molecules in the mixed air flow is conducted by the plate-shaped structure, the liquid water molecules are condensed on the plate-shaped structure so as to separate the liquid water molecules from the gaseous water molecules in the mixed air flow, and the steam of the liquid water molecules in the mixed air flow is guided out from the steam outlet 12 to the clothes holding cylinder of the clothes care device after passing through the channel so as to provide steam for clothes in the clothes holding cylinder to be dried by steam or removed by the steam or sterilized by the steam, and the liquid water molecules guided out from the steam outlet 12 are reduced. By utilizing the difference of the particle sizes of the gaseous water and the liquid water molecules, the gaseous water and the liquid water molecules are mixed and flow together to be in contact with the plate-shaped structure, the liquid water molecules are intercepted and attached to the outer surface of the plate-shaped structure and fall under the action of gravity, and the gaseous water flows to the steam outlet 12 through a channel arranged on the plate-shaped structure.
In one embodiment, the number of the plate-shaped structures is at least two, and the at least two plate-shaped structures are sequentially arranged along the flowing direction of the mixed gas flow so as to separate the mixed gas flow formed by heating the heating assembly for multiple times, thereby obtaining the gaseous water with higher purity. Further, the plane of the plate-shaped structure is parallel to the horizontal plane, so that the plate-shaped structure is fully oriented to the steam airflow and the size of the plate-shaped structure is reduced. Further, at least two plate-shaped structures are arranged in parallel, and the distances between the longitudinal parts of the two plate-shaped structures are the same or similar, so that the effect of separating the mixed gas flow at the parts of the two plate-shaped structures, which are positioned on the same longitudinal plane, is similar, and a stable mixed gas flow separation effect is provided. The mixed gas flow formed by heating the heating component contacts the first plate-shaped structure, part of liquid water molecules are separated and removed, part of liquid water molecules are still mixed in the separated gaseous water, the gaseous water continues to flow upwards, the second plate-shaped structure is contacted for carrying out the second mixed gas flow separation, and the like, the ascending mixed gas flow contacts the plurality of plate-shaped structures in sequence, and the mixed gas flow separation is repeated to gradually separate and remove the liquid water molecules in the mixed gas flow and retain water vapor.
In an embodiment, the cross-sectional areas of at least two plate structures sequentially arranged along the direction towards the steam outlet 12, which are perpendicular to the flowing direction of the mixed air flow, are the same, and the plate structures can be arranged at any position in the cavity of the shell 10, wherein the transverse spaces are similar.
In an embodiment, the cross-sectional areas of the at least two plate-like structures perpendicular to the flowing direction of the mixed air flow are different, so as to reasonably plan that the at least two plate-like structures occupy the transverse space in the housing 10, which is beneficial to miniaturization of the generator body 1.
In an embodiment, the cross-sectional areas of at least two plate structures sequentially arranged along the direction towards the steam outlet 12, which are perpendicular to the flowing direction of the mixed air flow, are sequentially reduced, so that the content of liquid water molecules in the mixed air flow mixture after the mixed air flow of the first plate structure contacted at first is greatly reduced, the size of the second plate structure contacted subsequently is properly reduced, the effect of separating the mixed air flow is ensured, the cost is saved, the space occupied by the corresponding plate structures in the shell 10 is saved, and the method comprises the steps of third plate structures and fourth plate structures with decreasing sizes. The horizontal space of the cavity of the shell 10 from bottom to top is sequentially reduced so as to reasonably plan the size of the generator body 1, thereby being beneficial to the miniaturization of the generator body 1. In an embodiment, the generator body 1 comprises a first plate-like structure and a second plate-like structure, which are arranged in parallel in a direction towards the steam outlet 12, the first plate-like structure and the second plate-like structure being similar, and the second plate-like structure having a smaller size than the first plate-like structure. In yet another embodiment, the cross-sectional areas of at least two plate-like structures sequentially arranged along the direction toward the steam outlet 12, which are perpendicular to the flow direction of the mixed air flow, are sequentially increased, and the lateral space of the cavity of the housing 10 from bottom to top is sequentially increased, so as to reasonably plan the size of the generator body 1, which is beneficial to miniaturization of the generator body 1.
In one embodiment, a plate-like structure remote from the heating assembly is disposed proximate to the steam outlet 12. The mixed air flow mixture can be quickly discharged from the steam air outlet 12 after being separated by a plate-shaped structure mixed air flow far away from the heating component, so that the situation that the plate-shaped structure farthest from the heating component is arranged from bottom to top in sequence is larger in distance from the steam air outlet 12, and the high-purity steam obtained after the last plate-shaped structure mixed air flow is separated in the ascending process of the mixed air flow is subjected to cold liquefaction to form liquid water in the process of flowing to the steam air outlet 12, so that the liquid water molecules are mixed in the steam discharged from the steam air outlet 12 or the quantity of the steam discharged from the steam air outlet 12 is reduced.
In one embodiment, the peripheral side of the plate-like structure abuts against the peripheral side of the inner wall of the housing 10, so that the mixed air flow must first contact the plate-like structure to be left to the steam outlet 12, and the separation effect of the mixed air flow is ensured.
Further, the plate-shaped structure comprises a first plate-shaped structure and a second plate-shaped structure which are sequentially arranged along the flowing direction of the mixed airflow, a first space is formed by the heating component, the first plate-shaped structure and the inner wall of the cavity of the shell 10, a second space is formed by the first plate-shaped structure, the second plate-shaped structure and the inner wall of the cavity of the shell 10, a third space is formed by the second plate-shaped structure and the inner wall of the cavity of the shell 10 towards one outer surface of the steam outlet 12, and the volumes of the first space, the second space and the third space are sequentially reduced. The liquid water is heated by the heating assembly to form a mixed air flow, the mixed air flow is sequentially contacted with the first plate-shaped structure and the second plate-shaped structure in the ascending process of the mixed air flow, the maximum amount of liquid water molecules mixed in the mixed air flow before the mixed air flow contacts the first plate-shaped structure is obtained after the two mixed air flows of the first plate-shaped structure and the second plate-shaped structure are separated, namely, the amount of liquid water molecules mixed in the mixed air flow is gradually reduced, namely, the amount of the mixed air flow contained in the three spaces of the first space, the second space and the third space is also sequentially reduced, so that in order to effectively reduce the size of the steam generator, the volumes of the first space, the second space and the third space are sequentially reduced, and enough spaces are reserved for accommodating the mixed air flow when the cavity space of the shell 10 is reduced, and the liquid water molecules in the accommodated mixed air flow collide with gaseous water and the gaseous water to form liquid water due to small spaces, so that the gaseous water is not reduced.
Specifically, a space is reserved between two adjacent plate-shaped structures, so that a space is provided for dispersing mixed gas flow between the two adjacent plate-shaped structures, the mixed gas flow with reduced liquid water molecule content obtained after the mixed gas flow passes through the first plate-shaped structure is prevented from being gathered in the too small space between the two adjacent plate-shaped structures, and the gaseous water is accelerated to form liquid water due to collision and/or collision between the gaseous water and the liquid water molecules, so that the separation effect of the mixed gas flow is influenced.
In order to ensure that the first plate-shaped structure adjacent to the heating assembly can quickly separate and remove a part of liquid water molecules, the distance between the first plate-shaped structure and the heating assembly is not too small, so that the mixed air flow formed by heating of the heating assembly is prevented from contacting the surface of the corresponding first plate-shaped structure in a large amount in a short time, and the condensed liquid water cannot be separated from the surface of the first plate-shaped structure in time, which is not beneficial to the separation of the mixed air flow. The liquid water molecule content in the mixture of the mixed gas flowing upwards continuously after the first mixed gas flow separation is carried out through the first plate-shaped structure is lower, so that the space between two adjacent plate-shaped structures is not required to be too large, and the second, third or even more mixed gas flow separation can be smoothly carried out, thereby saving the size of the generator body 1.
In one embodiment, the plate-shaped structure is a filter screen 30, the filter holes of the filter screen 30 form channels of the plate-shaped structure, and the filter screen 30 has a simple structure and is easy to install. The mixed air flow contacts with the filter screen, the gaseous water can pass through the filter holes of the filter screen, the liquid water molecules are intercepted and attached to the surface of the filter screen 30, the liquid water is formed by condensation, and the liquid water falls into the water in the shell 10 under the gravity of the liquid water, so that the mixed air flow separation is realized. Further, a plurality of layers of filter screens 30 are disposed in the housing 10 along the longitudinal direction of the housing 10, and the steam outlet 12 is located at the top end of the housing 10 or near the top end of the housing 10 to enhance the separation effect of the mixed gas flow.
In a further embodiment, a space is provided between the plate-like structure and at least one inner wall of the cavity of the housing 10 to form said channel. The rising mixed air flow contacts the outer wall of the plate-shaped structure, liquid water molecules are attached to the outer wall of the plate-shaped structure to form liquid water, then the liquid water falls, the flowing direction of the air flow is changed after the gaseous water contacts the plate-shaped structure, the air flow flows to the channel, and the air flow passes through the channel and then flows to the steam outlet 12.
In one embodiment, the filter screen 30 is a flat plate structure, and liquid water molecules are intercepted and attached to the surface of the filter screen 30 to condense and form liquid water, and then naturally fall. In yet another embodiment, the screen 30 is concave or convex in configuration facing the heating element.
When the filter screen 30 is of a concave structure facing the heating assembly, liquid water molecules are intercepted and are condensed to form liquid water after adhering to the surface of the concave part of the filter screen 30, the liquid water adhering to the middle part of the concave part of the filter screen 30 flows along the direction facing the outer periphery side of the concave part, and the surface of the concave part of the liquid water moves at an acceleration due to the slope of the concave part adhering to the surface of the concave part when flowing as the liquid water. Part of the liquid water falls down in the process of flowing in the direction of the outer peripheral side of the concave part, and the other part of the liquid water flows to be converged near the outer peripheral side of the concave part under the action of acceleration to fall down. The liquid water does acceleration motion on the concave part, and is not easy to stay on the surface of the filtering holes of the filtering net 30 due to the surface tension of the liquid water, so that the separation speed of the mixed air flow is accelerated. Further, the joint part extends from the outer peripheral side of the inner concave part, the plane of the joint part is perpendicular to the gravity direction of the liquid water, the liquid water flowing from the middle part of the inner concave part to the outer peripheral side edge of the inner concave part extends and adheres to the surface of the joint part, so that the liquid water collected at the outer peripheral side edge of the inner concave part is prevented from being excessive to block the filter holes at the periphery side of the outer peripheral side edge of the inner concave part, the effective area of the plate-shaped structure for separating the mixed gas flow is reduced, and the mixed gas flow separation is prevented from being influenced. As shown in fig. 1, 3 and 4, specifically, a first filter screen 31 and a second filter screen 32 are sequentially disposed in the casing 10 from bottom to top along the longitudinal direction of the casing 10, the first filter screen 31 and the second filter screen 32 are disposed in parallel along the direction towards the steam outlet 12, the size of the second filter screen 32 is smaller than that of the first filter screen 31, and the first filter screen 31 and the second filter screen 32 are both concave structures facing the heating component. The first engaging portion 312 is provided on the outer peripheral side of the first concave portion 311 of the first screen 31, and the second engaging portion 322 is provided on the outer peripheral side of the second concave portion 321 of the second screen 32.
When the filter screen 30 is in a convex structure facing the heating assembly, after liquid water molecules are intercepted and adhered to the surface of the outer flange of the filter screen 30 and condensed into liquid water, the liquid water adhered to the peripheral side of the outer flange of the filter screen 30 flows along the middle part of the outer flange, and the outer flange adhered to the filter screen 30 has a gradient when flowing as liquid water, and the liquid water moves on the surface of the outer flange at an acceleration. Part of liquid water falls in the process of flowing to the middle part of the outer convex part, and the other part of water is collected to the convex part of the outer convex part under the action of acceleration, so that the water drop size of the liquid water is increased, and the gravity is increased to accelerate the falling. The liquid water does acceleration motion on the outer flange, and is not easy to stay on the surface of the filtering holes of the filtering net 30 due to the surface tension of the liquid water, so that the separation speed of the mixed air flow is accelerated. However, since the liquid water flows from the peripheral side of the outer flange to the middle of the outer flange and is collected in the middle, and the area of the middle of the outer flange is relatively small, the liquid water droplets become large, which may block part of the filtering holes in the middle of the outer flange, reducing the effective area of the plate structure for separating the mixed gas flow, which affects the mixed gas flow separation to a certain extent, and the effect is slightly weaker than the mixed gas flow separation effect when the filter screen 30 is in a concave structure facing the heating assembly. Further, the outer convex structure of the filter screen 30 includes a first outer convex portion and a second outer convex portion (not shown in the figure), the first outer convex portion is located at the outer peripheral side of the second outer convex portion, an included angle between the first outer convex portion and a horizontal plane is larger than an included angle between the second outer convex portion and the horizontal plane, and the first outer convex portion and the second outer convex portion are connected through a connecting portion which is an arc surface. The acceleration of the liquid water attached to the first outer protruding portion flowing in the direction of the second outer protruding portion is greater than the acceleration of the liquid water on the peripheral side of the second outer protruding portion flowing in the middle portion of the second outer protruding portion. In the process that the liquid water attached to the first outer convex part flows towards the second outer convex part, one part of the liquid water falls, the other part of the liquid water flows onto the second outer convex part, the liquid water which is originally attached to the second outer convex part is collected to continuously flow along the direction of the periphery of the second outer convex part towards the middle part of the second outer convex part, in the flowing process, one part of the liquid water falls, and finally, the amount of the liquid water flowing towards the middle part of the second outer convex part is less, so that the probability that the liquid water blocks the filtering holes of the middle part of the second outer convex part is reduced, and the mixed airflow separation effect is improved.
Further, the concentration of the filter holes of the filter screen 30 in the concave structure or the convex structure is lower at the position close to the heating assembly than at the position far away from the heating assembly. Further, the filter screen 30 having a concave structure or a convex structure has a larger pore diameter at a portion close to the heating element than at a portion of the filter screen 30 distant from the heating element.
When the filter screen 30 is concave toward the heating element, in one embodiment, a peripheral portion of the concave portion of the filter screen 30 is closer to the heating element than a central portion thereof, the central portion of the concave portion of the filter screen 30 is farther from the heating element than the peripheral portion thereof, and the concentration of the filter holes at the peripheral portion of the concave portion of the filter screen 30 is lower than that at the central portion of the concave portion.

The plate-like structure is provided with channels (not shown) through which nuts are passed for securing with the connecting posts 18.
In one embodiment, the heating assembly includes a heating tube assembly. The water contacted with the heating pipe component is heated by the heat transferred to the surface of the heating pipe by the heating unit in the heating pipe, and the heating end of the heating component is formed on the surface of the heating pipe. If the water only submerges the local part of the heating pipe, the heat on the surface of the heating pipe exposed to the water surface is dissipated to the space outside the water surface in the shell 10, and the mixed air flow at the local part is heated, so that part of the liquid water is gasified into gaseous water.
In yet another embodiment, the heating assembly comprises a thick film heating assembly 20, the plate-like structures being arranged in parallel, and further the thick film heating assembly 20, the plate-like structures being parallel to a horizontal plane. The thick film heating element 20 is flat, thin, small in size, and ensures a sufficient heat conduction area. Further, the thick film heating element 20 is disposed at the bottom of the casing 10, the water inlet 11 may be disposed at any position of the casing 10 along the direction of the thick film heating element 20 toward the steam outlet 12, and water falls onto the thick film heating element 20 at the bottom of the casing 10 under the gravity of water after being introduced from the water inlet 11, so as to contact with the thick film heating element 20 for heating, i.e. the position selection range of the water inlet 11 is enlarged.
Further, as shown in fig. 5, the thick film heating assembly 20 comprises a heat conducting substrate 21, an inner insulating medium layer 22, a resistance heating layer 23 and an outer insulating layer (not shown in the figure) which are sequentially arranged, the thick film heating assembly 20 further comprises an electrode end 24 electrically connected with the resistance heating layer 23 so as to be electrically connected with a control circuit of the clothes treatment device, the control circuit is electrically connected with a power module in the clothes care device, and the resistance heating layer 23 is switched to an on-off mode through the on-off of the control circuit, namely, the on-off of the control circuit is used for starting or stopping the heating of the resistance heating layer 23. The resistance heating layer 23 emits heat after the thick film heating assembly 20 is electrified, the heat is conducted to the heat conducting substrate 21, so that the temperature of the heat conducting substrate 21 is increased to heat water in contact with the heat conducting substrate 21, in addition, the heat conducting substrate 21 with the increased temperature enables the ambient air temperature at the periphery side of the heat conducting substrate 21 to be increased, and the water in the shell 10 is indirectly heated. The thermally conductive substrate 21 forms the heating end of the heating assembly. The heat conducting substrate 21 is an insulating member with high heat conductivity, and in one embodiment, the heat conducting substrate 21 is a stainless steel substrate. The inner insulating dielectric layer 22 protects the thermally conductive substrate 21 from electrical charges, which would result in electrical charges in the housing 10. The outer insulating layer insulates the outside of the resistance heat layer 23 from the outside.

At present, if a heating component is easy to form scale, the steam generator for the clothes treatment device is unrealistically and difficult to realize when the clothes treatment device is disassembled to take out the steam generator for cleaning. If the heating element is fragile, it cannot be replaced. And because the clothes treatment device is used for treating clothes, the water quality is not as good as the drinking water, and the water quality of the water is controlled due to the requirement of the heating component on the water quality, the cost is high and the water quality is unrealistic. In this embodiment, the thick film heating assembly 20 is formed by sequentially printing the inner insulating medium layer 22, the resistance heating layer 23 and the outer insulating layer on the heat conducting substrate 21 by adopting a screen printing technology, and the heat conduction distance from the resistance heating layer 23 to the heat conducting substrate 21 is short, so that the thermal resistance is small, the thermal response speed is high, heat can be timely conducted away, the surface temperature of the whole thick film heating assembly 20 cannot be too high, the use safety is high, scale is not easy to form, and the requirement on water quality is not high.

Further, the periphery of the heat conducting substrate 21 of the thick film heating assembly 20 abuts against the inner wall of the housing 10, so that the water entering the housing 10 from the water inlet 11 can only contact the heat conducting substrate 21 of the thick film heating assembly 20, and the heat emitted by the resistance heating layer 23 of the thick film heating assembly 20 is conducted to the heat conducting substrate 21, so that the heat conducting substrate 21 heats the water in the housing 10. So as to prevent water from contacting the resistance heating layer 23 to generate electric leakage after the outer insulating layer of the thick film heating assembly 20 is damaged. Meanwhile, water entering the housing 10 from the water inlet 11 contacts the surface of the heat conducting substrate 21 exposed to the outside with the largest surface area, and is heated quickly. In an embodiment, the thick film heating assembly 20 is disposed at the bottom of the housing 10, and since the peripheral side of the heat conducting substrate 21 of the thick film heating assembly 20 abuts against the inner wall of the housing 10, the heat conducting substrate 21 divides the inner cavity of the housing 10 into two independent spaces, and after entering the housing 10 from the water inlet 11, external water is blocked from continuing to fall down when contacting the heat conducting substrate 21, so that the space for accommodating water in the inner cavity of the housing 10 is increased by disposing the thick film heating assembly 20 at the bottom of the housing 10, i.e. for the generator body 1 injecting the same amount of water, the size of the generator body 1 when disposing the thick film heating assembly 20 at the bottom of the housing 10 is relatively small, thereby saving space.

Further, the sealing ring 25 is provided with a first clamping groove for clamping the periphery of the heat conducting substrate 21 to firmly fix the heat conducting substrate 21.
