Detailed Description

First, it should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present invention, and are not intended to limit the scope of the present invention. And can be adjusted as needed by those skilled in the art to suit particular applications. For example, although the vapor-liquid separation assembly of the present invention has been described in connection with an ironing appliance, it is clear that the vapor-liquid separation assembly could also be used in other steaming appliances having the same vapor-liquid separation requirements, such as a laundry machine or the like.

It should be noted that in the description of the present invention, the terms of direction or positional relationship indicated by the terms "upper", "lower", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, which are merely for convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

Furthermore, it should be noted that, in the description of the present invention, unless otherwise explicitly specified or limited, the terms "connected" and "connected" should be interpreted broadly, e.g., as being fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Ironing devices generally comprise both hand-held ironing devices and automatic ironing devices. In particular, the steam nozzle of the hand-held ironing device can be held movable by a user, who can hold the steam nozzle to move relative to the laundry to be ironed in a situation in which the laundry to be ironed is placed, in order to iron various positions of the laundry. The automatic ironing equipment is characterized in that a steam nozzle can directly spray steam to clothes to be ironed and iron various positions on the clothes to be ironed. The user only needs to place the clothes to be ironed at the corresponding position of the steam nozzle, and does not need to hold the steam nozzle in the ironing process. The solution of the invention will be elucidated below in connection with the above described automatic ironing device.

Referring first to fig. 1, fig. 1 is a schematic view of the overall structure of the ironing apparatus of the present invention. As shown in fig. 1, the ironing apparatus of the present invention comprises a cabinet housing, an ironing space 1 and a receiving chamber 2 formed inside the cabinet housing. The receiving chamber 2 communicates with the ironing space 1. The ironing device further comprises steam spraying means 3 and a steam generator (not shown in the figures). The steam injection member 3 includes a nozzle 31 and a steam guide 32 (described in detail below with reference to fig. 2), and one end of the steam guide 32 communicates with the steam generator and the other end communicates with the nozzle 31. The steam injection member 3 and the steam generator are arranged in the receiving cavity 2 with the nozzle 31 facing the ironing space 1 so that the high temperature steam generated by the steam generator can be ejected to the ironing space 1 through the steam conduit 32 and the nozzle 31. When a user places the clothes to be ironed in the ironing space 1 by hanging, etc., the steam sprayed from the spray head 31 can iron the clothes to be ironed placed in the ironing space 1.

Since the high-temperature steam sprayed out of the steam generator is a mixed steam of steam and steam, the ironing device further comprises a gas-liquid separation assembly 4 arranged between the steam generator and the steam spraying member 3. The gas-liquid separation assembly 4 is arranged to be capable of separating steam and steam sprayed by the steam generator, so that mixed steam of the steam and the steam sprayed by the steam generator can be separated when flowing through the gas-liquid separation assembly 4, and the steam is prevented from being sprayed out when the steam spraying component 3 sprays out the steam. That is, the gas-liquid separation assembly 4 can separate and filter the mixed gas of the steam and the water vapor ejected from the steam generator to prevent the water vapor from being ejected from the spray head 31.

In the above embodiment, the "steam" mainly refers to large particle droplets in the mixed steam ejected from the steam generator, and the large particle droplets will be ejected onto the clothes to be ironed in the form of large droplet liquid to moisten the clothes, which will affect the ironing effect of the creases; the above-mentioned "steam" mainly refers to the high-temperature small particle droplets in the mixed steam ejected from the steam generator, which can perform the ironing function, and the small particle droplets will be ejected onto the clothes to be ironed in the form of steam.

In connection with the above, it should be noted that, firstly, although the ironing apparatus of the present invention is described in connection with the cabinet type automatic ironing apparatus, this is not limitative, and other configurations of automatic ironing apparatus or hand-held ironing apparatus may also be provided with the above-mentioned air-liquid separation assembly 4, i.e. the configuration of the ironing apparatus is not exclusive.

Next, the arrangement of the gas-liquid separation module 4 is not limited. The above-mentioned "the gas-liquid separation module 4 is disposed between the steam generator and the steam injection member 3" mainly means that the gas-liquid separation module 4 is disposed between the shower head 31 of the steam injection member 3 and the steam injection structure on the steam generator. For example, in one possible case, the steam generator is directly connected to the steam injection member 3, and the gas-liquid separation assembly 4 is disposed on the steam generator downstream of the steam ejection structure (i.e., on the steam outflow side of the steam ejection structure). In another possible case, the steam generator is directly connected to the steam spraying member 3, and the gas-liquid separation assembly 4 is disposed on the steam spraying member 3 (e.g., on the steam guide pipe 32) upstream of the steam ejection port of the showerhead 31 (i.e., on the steam inflow side of the showerhead 31). In yet another possible scenario, the steam generator is in indirect communication with the steam injection means 3 through the gas-liquid separation assembly 4. The preferred embodiments of the present invention will be further described with reference to the last case.

Referring next to fig. 2, fig. 2 is a schematic structural view of the air/liquid separating assembly of the ironing apparatus of the present invention, and as shown in fig. 2, the air/liquid separating assembly 4 includes a body 41 and a separating member 42. A pipe passage is formed in the body 41 and has one end communicating with the steam generator and the other end communicating with the steam guide pipe 32 so as to form a flow path of the steam between the steam generator and the shower head 31. A separating member 42 is disposed within the conduit channel. When the gas flows through the position of the separation member 42 of the pipeline, the separation member 42 can prevent the steam in the mixed gas from continuously flowing, and the steam in the mixed gas continuously flows after passing through the separation member 42, so that only the steam is sprayed out of the spray head 31.

As a possible embodiment, the separating member 42 is a sieve arranged in the above-mentioned pipe passage. The filter screen is fixed along the cross section direction of the pipeline channel (including the transverse section direction and the transverse section direction with gradient) by means of bonding, clamping, screwing and the like. The structural form of the filter screen is not limited. For example, the filter screen may be a single-layer screen structure having dense mesh openings, or a screen structure having dense pore diameters formed by overlapping multiple layers of screens. Of course, the separating member 42 may be other filtering structures besides a screen. For example, a block structure having a dense pore diameter penetrating therethrough is formed inside.

Further, the pipe channel comprises a steam guiding-out section 411 and a separation cavity 412, one end of the steam guiding-out section 411 is communicated with the steam generator through the separation cavity 412, and the other end is communicated with the steam conduit 32, wherein the area of the cross section of the steam guiding-out section 411 is reduced along the flow direction of the steam, so that the steam can enter the steam conduit 32 in a centralized manner, and the condensation degree of the steam in the flow process is reduced to a certain extent. As an example, the area of the cross section of the steam lead-out section 411 is gradually reduced in the flow direction of the steam, so that the steam lead-out section 411 is formed as an inverted conical channel. The separation chamber 412 is a cylindrical passage, and the cross-sectional dimension of the cylindrical passage is equal to the maximum cross-sectional dimension of the steam leading-out section 411, so that a large enough filtering space is provided in the separation chamber 412, the separation efficiency is ensured, and the steam separated in the separation chamber 412 is guided in a concentrated manner and gathered together continuously after entering the steam leading-out section 411, so as to prevent the condensation after the escape of part of the steam.

With continued reference to FIG. 2, the gas-liquid separation assembly 4 preferably further includes a flow guide member 43. According to the orientation of fig. 2, the direction of the arrows in fig. 2 is the flow direction of the steam, and the flow guide member 43 is arranged upstream of the separating member 42, i.e. on the underside of the separating member 42. One end of the flow guide member 43 communicates with the separation chamber 412, and the other end communicates with the outside of the pipe passage. When the vapor is blocked and collected below the separation chamber 412 by the separation member 42, the flow guide member 43 can guide the liquid formed by the condensation of the vapor to flow out of the pipeline channel, so as to avoid the influence of a large amount of liquid accumulated in the pipeline channel on the flow of the vapor.

As shown in fig. 2, the flow guide member 43 includes a converging structure 431 and a leading structure 432 in communication. The converging structure 431 can converge the liquid into the leading-out structure 432, the converging structure 431 is arranged on the lower side of the separating member 42 and is communicated with the separating cavity 412, and the leading-out structure 432 is communicated with the outside of the pipeline channel, so that the liquid condensed from the water vapor in the separating cavity 412 can be converged and led out of the pipeline channel. As an example, converging structure 431 is in the shape of an inverted cone, and leading-out structure 432 is a tubular structure disposed at the end of the cone of converging structure 431.

As a preferred embodiment, the ironing apparatus of the present invention further comprises a water box (not shown in the figures) communicating with the flow-guide member 43, so that the liquid guided by the flow-guide member 43 from the passage of the circuit can be contained in the water box. Specifically, the water box is communicated with the leading-out structure 432, so that the liquid in the pipeline channel can be discharged from the pipeline channel through the flow path of the converging structure 431-the leading-out structure 432-the water box.

In order to prevent the liquid in the channel from flowing backwards into the steam generator, the ironing device of the present invention preferably further comprises a steam introduction member 5. As shown in fig. 2, the steam introduction member 5 is exemplarily a tubular structure. The lower end of the tubular structure is a steam inlet end which is communicated with the steam generator. The upper end of the tubular structure is a vapor outlet end which communicates with the separation chamber 412. The port of the steam outlet is protruded relative to the flow guide surface on the inner side of the flow guide member 43, so that the liquid can flow out around the steam outlet when flowing along the flow guide surface, thereby preventing the liquid from entering the steam outlet and flowing back into the steam generator.

As a specific embodiment, the steam introduction member 5 is provided by: the converging structure 431 is provided with an inclination to deflect the outlet structure 432 with respect to the central axis of the duct channel, avoiding the steam inlet member 5. The steam introduction member 5 is provided in such a manner that the steam outlet protrudes into the convergence structure 431 so as to protrude with respect to the inner side surface of the convergence structure 431, thereby protruding the steam outlet while communicating the pipe passage.

It will be understood by those skilled in the art that, first, the shape of the body 41 and the shape of the pipe passage therein are not limited to the above-described structure, and for example, the steam outlet section of the pipe passage may be consistent with the pipe diameter of the separation chamber 412. The main body 41 may be a cylindrical structure, in addition to being adapted to the shape of the pipe wall of the pipe passage, as long as the pipe passage formed inside the main body 41 can satisfy the steam circulation requirement. Secondly, the shape of the flow guiding member 43 is not limited to the converging structure 431 and the leading structure 432, as long as the flow guiding member 43 is configured to meet the flow guiding requirement of the liquid. For example, the flow guide member 43 may also be a straight tube structure. The shape and arrangement of the steam introducing member 5 are not limited. For example, when the communication position of the steam introduction member 5 on the pipe passage is higher than the flow guide member 43, the steam outlet end of the steam introduction member 5 may not be provided to protrude. The steam introducing member 5 may be a bent pipe structure such as an S-shaped pipe, in addition to the straight pipe structure shown in fig. 2, as long as the steam introducing member 5 can satisfy the steam introducing requirement.

In summary, the ironing device of the present invention comprises a steam generator, a steam spraying means 3 and a gas-liquid separating assembly 4, wherein the gas-liquid separating assembly 4 comprises a body 41 having a duct channel formed therein, a separating means 42 and a flow guiding means 43 arranged in the duct channel. One end of the pipeline channel is communicated with the steam generator, and the other end of the pipeline channel is communicated with the steam injection component 3, so that the separation component is arranged on the flow path of the steam, the steam in the steam can be separated by the separation component 42, and the steam is prevented from being sprayed out when the steam is sprayed out of the steam injection component 3. The guide member 43 is disposed upstream of the separation member 42 so as to guide the liquid generated by condensing the separated water vapor out of the pipeline to ensure sufficient circulation of the vapor.

So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
