Description

Technical Field

[0002] The existing ironing device includes a water tank and a steam chamber. The steam chamber is located above the ironing board of the ironing device. After the water in the water tank enters the steam chamber, it is heated by the ironing board to form steam, which is ejected from the steam holes on the ironing board for the user to iron clothes. The amount of steam can generally be adjusted for different occasions and different ironing objects, but the heating power of the heating unit is generally fixed. Therefore, if the water supply entering the steam chamber is adjusted, the amount of steam and the heating power will not match. As a result, when in use, either the amount of steam generated is small and the heating power is large, resulting in low energy efficiency of the steam device, or the amount of steam generated is large and the heating power is small, resulting in steam dripping, which greatly reduces the ironing effect.

It should be noted that the following are only certain specific implementation methods of the present invention, which are only part of the embodiments of the present invention, wherein the specific and direct description of the relevant structures is only for the convenience of understanding the present invention, and each specific feature does not naturally and directly limit the scope of implementation of the present invention. The conventional selections and substitutions made by those skilled in the art under the guidance of the present invention shall be deemed to be within the scope of protection claimed by the present invention.

[0044] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0045] Example 1

[0046] like Figure 1-4 As shown, the utility model provides an ironing device with adjustable flow rate and heating power, including a housing, a container 1 for storing water, a steam chamber located at the bottom of the container 1, and a heating control circuit installed in the housing, the heating control circuit including a heating unit 6 for heating the steam chamber, and a heating gear switch for adjusting the heating power of the heating unit 6. The container 1 is provided with a water outlet 2, specifically located at the bottom of the container 1. The steam chamber is provided with a water inlet channel 3 arranged opposite to and connected to the water outlet 2, and the water inlet channel 3 is connected to the internal space of the steam chamber. Among them, the sealing silica gel on the steam chamber is located at the bottom of the container 1 and abuts against it, and the water inlet channel 3 is specifically located at the top of the sealing silica gel.

[0047] A flow regulating component 4 is provided between the water outlet 2 and the water inlet channel 3. In one embodiment, Fig.12As shown, a water receiving groove is provided on the sealing silicone of the steam chamber, and the water inlet channel 3 is a groove provided in the water receiving groove of the steam chamber. A notch 5 is provided on the side wall of the groove to allow water to flow between the container and the sealing silicone.

[0048] like Figure 1 As shown, the flow regulating assembly 4 includes a flow level switch 41 movably arranged on the shell, and a first valve stem 42 vertically penetrating the container 1 and the steam chamber.

[0049] The heating gear switch is installed on the flow gear switch 41. The top of the flow gear switch 41 is provided with a protrusion 411. Of course, it is also feasible to set it in a concave shape, which is mainly to facilitate the horizontal sliding of the flow gear switch 41 to achieve the up and down adjustment of the first valve stem 42. The middle part of the first valve stem 42 is provided with annular bosses in the vertical direction, and an annular groove for installing a sealing ring is formed between the two annular bosses.

[0050] The flow level switch 41 is arranged to slide horizontally and is provided with a slide rail 43 extending obliquely in the sliding direction. The slide rail 43 is arranged at one end of the flow level switch 41 and is a slide groove open on one side. The slide rail 43 includes two first horizontal sections 431 and a first inclined section 432 connecting the two first horizontal sections 431. The first inclined section 432 is specifically arranged to be inclined upward from the bottom of the flow level switch 41 to the top thereof, so that there is a height difference between the two first horizontal sections 431 in the vertical direction.

[0051] like Figure 4 As shown, the top of the first valve stem 42 passes through the housing and is provided with a sliding portion 421 that slides on the slide rail 43. The sliding portion 421 is specifically a convex column that is provided on the top side wall of the first valve stem 42 and provided on the slide groove. The bottom of the first valve stem 42 is a variable cross-section structure 44. The first valve stem 42 passes through the water outlet 2 and there is a gap therebetween. The variable cross-section structure 44 is provided on the water inlet channel 3 and cooperates with the water outlet 2 to form a flow channel for water to flow in, that is, there is a gap between the outer side wall of the variable cross-section structure 44 and the inner side wall of the water outlet 2. In another embodiment, the variable cross-section structure 44 can also be provided to cooperate with the water inlet channel 3 to form a flow channel for water to flow in.

[0052] The flow gear switch 41 is driven to slide horizontally, driving the heating gear switch to move to different gears, and at the same time driving the sliding part 421 of the first valve stem 42 to slide back and forth on the slide rail 43, so that the first valve stem 42 moves up and down to adjust the size of the gap between the variable cross-section structure 44 and the water outlet 2, so that two different flow rates of water can enter the steam chamber for vaporization, thereby generating two amounts of steam.

[0053] In this embodiment, the variable cross-section structure 44 includes a drainage groove 45 provided on the side wall of the bottom of the first valve stem 42 and extending to the bottom thereof, wherein the drainage groove 45 is provided on the outer side wall of one side of the bottom of the first valve stem 42, and can also be symmetrically provided on the outer side wall of the bottom of the first valve stem 42. The bottom of the drainage groove 45 includes a second inclined section 451 and a vertical section 452 connected to each other, wherein the upper end of the vertical section 452 is connected to the lower end of the second inclined section 451, so that the gap between the bottom of the drainage groove 45 and the inner side wall of the water outlet 2 is variable, specifically, the gap between the second inclined section 451 and the inner side wall of the water outlet 2 is smaller than the gap between the vertical section 452 and the inner side wall of the water inlet channel 3. As another embodiment, the bottom of the drainage groove 45 is inclined so that the groove depth at the bottom of the drainage groove 45 is greater than the groove depth at the top thereof.

[0054] As another embodiment of the drainage groove 45 , the variable cross-section structure 44 is a tapered portion that is wider at the top and narrower at the bottom.

[0055] like Figure 1 , 8 As shown, preferably, the ironing device further includes a power switch 7, the heating unit 2 includes a first heating body 8 and a second heating body 9, and the heating gear switch is a first control switch J1. After the first heating body 8 and the second heating body 9 are connected in series, one end thereof is electrically connected to a first end of a power supply terminal 10 through the power switch 7, and the other end thereof is electrically connected to a second end of the power supply terminal 10, the first control switch J1 is connected in parallel to both ends of the second heating body 9, and the power supply terminal 10 is an AC power supply, and a rechargeable power supply can also be used to power the heating control circuit.

[0056] The first heating body 8 and the second heating body 9 are both heating tubes. By adjusting the first control switch J1 to change the connection mode of the two heating tubes and control the heating power of the heating control circuit, the first heating body 8 can work alone and the first heating body 8 and the second heating body 9 can work in series. At this time, the power of the first heating body 8 and the second heating body 9 can be the same or different.

[0057] In this embodiment, the first control switch J1 is located at the bottom of the other end of the flow level switch 41 .

[0058] like Figure 2 , 3 As shown, when the flow position switch 41 slides horizontally to the right, it also drives the first control switch J1 and the first valve stem 42 to move. When the first valve stem 42 is located on the first horizontal section 431 at the left end of the slide rail 43, the inner wall of the water inlet channel 3 faces the second inclined section 451. At this time, the water flow entering the water outlet 2 is relatively small; at the same time, the first control switch J1 is in the disconnected state, and the first heating body 8 and the second heating body 9 are in the series working mode. At this time, the heating power of the heating unit 6 is also relatively small, so that the water flow in the steam chamber and the heating power of the heating unit 6 are simultaneously reduced.

[0059] like Figure 2 , 3 As shown, when the flow gear switch 41 slides horizontally to the left, it also drives the first control switch J1 and the first valve stem 42 to move. When the first valve stem 42 is located on the first horizontal section 431 at the right end of the slide rail 43, the inner wall of the water inlet channel 3 is opposite to the vertical section 452. At this time, the water flow entering the water outlet 2 increases; at the same time, the first control switch J1 is in a closed state, and the first heating body 8 is in a single working mode. At this time, the heating power of the heating unit 6 increases, thereby achieving a synchronous increase in the water flow in the steam chamber and the heating power of the heating unit 6.

[0060] Since the ironing device can adjust the flow rate through a mechanical structure, there is no need to set a water pump. In order to prevent water from flowing out of the container through the steam chamber and the ironing board when the ironing device is not in use, it is preferred that Fig.12 As shown, the sealing silicone of the steam chamber is also provided with a water inlet 11 connected to its internal space, which is specifically connected to the water tank. An adjusting switch is also movably installed on the shell, and a second valve stem 12 is installed on the adjusting switch, which is penetrated by the container 1 and the steam chamber. The bottom of the second valve stem 12 is penetrated by the water inlet 11. When the adjusting switch is driven, the second valve stem 12 is driven to move up and down, so that the bottom of the second valve stem 12 cooperates to open or close the water inlet 11. By controlling the adjusting switch separately, the up and down movement of the second valve stem 12 is controlled to seal the water inlet 11 or open the water inlet 11. When the adjusting switch opens the water inlet 11, the flow entering the steam chamber is adjusted by the first valve stem 42, and the water outlet 2, the water inlet channel 3, and the water inlet 11 are connected in sequence.

[0061] In this embodiment, the regulating switch is a button or a vertical slide button or has the same structure as the flow gear switch. The second valve stem 12 is a silicone valve stem, and a sealing ring is provided on the silicone valve stem to ensure the sealing performance between the water inlet 11 and the container 1 respectively.

[0062] The bottom side wall of the second valve stem 12 is provided with a water groove 12a extending to the bottom thereof. When the second valve stem 12 moves upward, the water groove 12a is opposite to the inner wall of the water inlet 11 and there is a gap between the two for water to flow between the steam chamber and the container. When the second valve stem 13 moves downward, it seals with the water inlet 11. In another embodiment, the bottom of the second valve stem 12 is a tapered portion that is wide at the top and narrow at the bottom. As the second valve stem 12 moves up and down, the tapered portion seals with the inner wall of the water inlet 11 or there is a gap for water to flow.

[0063] Example 2

[0064] like Fig. 9As shown, the heating control circuit of the ironing device further includes a power switch 7, the heating unit 6 includes a first heating body 8 and a second heating body 9, and the heating gear switch is a first control switch J2. The difference between this embodiment and embodiment 1 is that the first heating body 8 and the second heating body 9 in the heating control circuit are connected in parallel.

[0065] After the first end of the first heating body 8 is connected to the first end of the second heating body 9, it is electrically connected to the first end of the power supply terminal 10 through the power switch 7. The second control switch J2 is connected in series with the second heating body 9 and then connected to the second end of the first heating body 8. The second control switch J2 is electrically connected to the second end of the power supply terminal 10.

[0066] By adjusting the second control switch J2 to change the connection mode of the two heating tubes, the first heating body 8 can work alone, and the first heating body 8 and the second heating body 9 can work in parallel. At this time, the power of the first heating body 8 and the second heating body 9 can be the same or different.

[0067] In this embodiment, the second control switch J2 is located at the bottom of the other end of the flow level switch 41 .

[0068] When the first valve stem 42 is located on the first horizontal section 431 at the left end of the slide rail 43, the inner side wall of the water outlet 2 faces the second inclined section 451, and the second control switch J2 is in an open state. When the first valve stem 42 is located on the first horizontal section 431 at the right end of the slide rail 43, the inner side wall of the water outlet 2 faces the vertical section 452, and the second control switch J2 is in a closed state.

[0069] Example 3

[0070] The difference between this embodiment and embodiment 2 is that Fig.10 As shown, the heating control circuit of the ironing device further includes a power switch 7, the heating unit 6 includes a first heating body 8 and a second heating body 9, and the heating gear switch is a third control switch.

[0071] The moving contact of the third control switch is electrically connected to the first end of the power supply terminal 10 through the power switch 7, the first ends of the first heating body 8 and the second heating body 9 are electrically connected to the corresponding static contacts of the third control switch respectively, and the second ends of the first heating body 8 and the second heating body 9 are electrically connected to the second end of the power supply terminal 10 after being connected.

[0072] In this embodiment, the third control switch is a single-pole double-throw switch J3 and is located at the bottom of the other end of the flow level switch 41 .

[0073] By adjusting the single-pole double-throw switch J3 to change the connection mode of the two heating tubes, the first heating body 8 can work alone and the second heating body 9 can work alone. At this time, the heating powers of the first heating body 8 and the second heating body 9 are different. When the water flow rate is small, the working mode with small heating power corresponds.

[0074] Example 4

[0075] The difference between this embodiment and embodiment 1 is that Figure 5-7 As shown, the slide rail 43 includes three first horizontal sections 431 and two first inclined sections 432 connecting two adjacent first horizontal sections 431. The slide rail 43 is a slide groove provided at one end of the flow level switch 41 and open on one side. The variable cross-section structure (not shown in the figure) includes a drainage groove 45 provided on the side wall of the bottom of the first valve stem 42 and extending to the bottom thereof, wherein the drainage groove 45 is provided on the outer side wall of one side of the bottom of the first valve stem 42, and can also be symmetrically provided on the outer side wall of the bottom of the first valve stem 42. The bottom of the drainage groove 45 is inclined so that the groove depth at the bottom of the drainage groove 45 is greater than the groove depth at the top thereof.

[0076] As another embodiment, the variable cross-section structure is a tapered portion that is wider at the top and narrower at the bottom.

[0077] like Fig.11 As shown, the heating control circuit of the ironing device further includes a power switch 7, the heating unit 6 includes a first heating body 8 and a second heating body 9, and the heating gear switch is a fourth control switch. The fourth control switch is provided with two moving contacts, the moving contacts are electrically connected to the first end of the power supply terminal 10 through the power switch 7, the first ends of the first heating body 8 and the second heating body 9 are electrically connected to the corresponding static contacts of the fourth control switch respectively, and the second ends of the first heating body 8 and the second heating body 9 are electrically connected to the second end of the power supply terminal 10 after being connected. The power supply terminal 10 is an AC power supply, and a rechargeable power supply can also be used to power the heating control circuit.

[0078] In this embodiment, the fourth control switch is a double-pole double-throw switch J4 and is located at the bottom of the other end of the flow level switch 41 .

[0079] By adjusting the double-pole double-throw switch J4 to change the connection mode of the two heating tubes, the first heating body 8 can work alone, the second heating body 9 can work alone, and the first heating body 8 and the second heating body 9 can work in parallel. At this time, the heating powers of the first heating body 8 and the second heating body 9 are different. When the water flow rate is small, the corresponding working mode is when the heating power is small.

[0080] like Figure 5-7As shown, when the flow position switch 41 slides horizontally to the right to the bottom, the double-pole double-throw switch J4 and the first valve stem 42 are driven to move at the same time. When the first valve stem 42 is located on the first horizontal section 431 at the leftmost end of the slide rail 43, the inner wall of the water outlet 2 is directly opposite to the bottom of the drain groove 45 near the top. At this time, the water flow entering the water outlet 2 is relatively small; at the same time, one of the moving contacts of the double-pole double-throw switch J4 is in a closed state, and the first heating body 8 or the second heating body 9 (the one with smaller heating power among the first heating body 8 and the second heating body 9 is selected) is in a separate working mode. At this time, the heating power of the heating unit 6 is also relatively small, so that the water flow in the steam chamber and the heating power of the heating unit 6 are simultaneously reduced.

[0081] like Figure 5-7 As shown, when the flow position switch 41 slides horizontally to the left until the first valve stem 42 is located in the middle of the slide rail 43, the double-pole double-throw switch J4 and the first valve stem 42 are driven to move upward at the same time. When the first valve stem 42 is located on the first horizontal section 431 in the middle of the slide rail 43, the inner wall of the water outlet 2 is directly opposite to the bottom of the drainage groove 45 near the middle, and the water flow entering the water outlet 2 increases at this time; at the same time, one of the moving contacts of the double-pole double-throw switch J4 is in a closed state, and the first heating body 8 or the second heating body 9 (select the one with larger heating power between the first heating body 8 and the second heating body 9) is in a separate working state mode. At this time, the heating power of the heating unit 6 increases, thereby achieving a synchronous increase in the water flow in the steam chamber and the heating power of the heating unit 6.

[0082] like Figure 5-7 As shown, when the flow position switch 41 slides horizontally to the left to the bottom, the double-pole double-throw switch J4 and the first valve stem 42 are driven to move at the same time. When the first valve stem 42 is located on the first horizontal section 431 at the rightmost end of the slide rail 43, the inner wall of the water outlet 2 is directly opposite to the bottom of the drain groove 45, close to the bottom. At this time, the water flow entering the water outlet 2 is the largest; at the same time, the two moving contacts of the double-pole double-throw switch J4 are in a closed state, and the first heating body 8 and the second heating body 9 are in a parallel working mode. At this time, the heating power of the heating unit 6 is the largest, thereby achieving a synchronous increase in the water flow in the steam chamber and the heating power of the heating unit 6.
