TECHNICAL FIELD
[0001] The disclosure relates to the technical field of irons, and in particular to an iron unit and a steam iron.BACKGROUND
[0002] Chinese literature No. CN105088733A (filed on November 25th, 2015) discloses a steam iron, including an iron unit and a water tank unit. An ironing plate of the iron unit has a preheating channel surrounded oppositely by an electric heating tube left and right, two heating channels in communication with a rear end of the preheating channel, and a steam channel in communication with a front end of the heating channel. The preheating channel can guide water to flow close to the electric heating tube, and the heating channels are respectively located directly above the electric heating tube and surround the preheating channel left and right. The preheating channel, the heating channels and the steam channel are arranged in the ironing plate corresponding to the shape of the electric heating tube, so that water can be quickly heated, boiled and vaporized. Thus, the heating and vaporization time is greatly shortened, and a large amount of steam can be generated rapidly. However, the steam iron of this technical solution is only equipped with one electric heating tube. When a large amount of steam is generated continuously, the single electric heating tube cannot ensure the vaporization effect, causing the risk that the ironing steam may be accompanied by dripping water.SUMMARY
[0003] In view of the defects in the prior art, the disclosure provides an iron unit, which mainly solves the technical problem that when the existing steam iron having a single electric heating tube continuously generates a large amount of steam, the ironing steam may be accompanied by dripping water.
[0004] In order to achieve the above objective, the disclosure is realized by the following technical solution: An iron unit includes an ironing plate and a first electric heating tube. The ironing plate is provided with a preheating channel, a heating channel and a steam channel which are sequentially in communication with each other. The first electric heating tube is fixedly mounted on the ironing plate and corresponds to a back of the heating channel in position. The iron unit further includes a second electric heating tube. The second electric heating tube is configured to correspond to a back of a second half part of the preheating channel such that a double heating reinforcement area is formed at the second half part of the preheating channel.
[0005] Further, the first electric heating tube includes two heating tube sections that extend front and rear and are arranged oppositely on the ironing plate left and right. The heating channel includes two diverted heating grooves that extend front and rear and are arranged oppositely on the ironing plate left and right. A middle area generated by an enclosure of the two diverted heating grooves is the preheating channel. The two heating tube sections respectively correspond to backs of the two diverted heating grooves in position, and the two diverted heating grooves are both in communication with a rear end of the preheating channel.
[0006] Further, external influent water is configured to flow into the preheating channel from a front end of the preheating channel, and a middle position of a first half part of the preheating channel is formed with a middle bulge structure configured to divert the water in the preheating channel to flow toward left and right sides so as to be close to the two diverted heating grooves.
[0007] Further, the steam channel is in communication with front ends of the two diverted heating grooves.
[0008] Further, the steam channel includes two diverted steam grooves that extend front and rear and are arranged oppositely on the ironing plate left and right. The front ends of the two diverted heating grooves are provided with a heating groove communication section for communicating the two diverted heating grooves. Front ends of the two diverted steam grooves are in communication with the two diverted heating grooves through the heating groove communication section, and the two diverted steam grooves are respectively adjacent to the two diverted heating grooves and extend rearward.
[0009] Further, joints between the preheating channel and the heating channel are provided with multi-step portions going up step by step.
[0010] Further, joints between the multi-step portions and the heating channel are provided with retention grooves for retaining non-vaporized water.
[0011] Further, the second electric heating tube has a U-shaped structure.
[0012] Further, the ironing plate is further provided with a first thermostat for controlling the first electric heating tube and a second thermostat for controlling the second electric heating tube.
[0013] Further, the first thermostat has a mechanical thermostat structure, and the second thermostat has a temperature-based thermostat structure.
[0014] Based on the same inventive concept, the disclosure further provides a steam iron, including the iron unit according to any of the above.
[0015] The above technical solution has the following advantages or beneficial effects:
[0016] In the iron unit and the steam iron of the disclosure, the ironing plate is provided with the preheating channel, the heating channel and the steam channel, the ironing plate is further provided with the first electric heating tube and the second electric heating tube, and the second electric heating tube is configured to correspond to the back of the second half part of the preheating channel. In this way, compared with the steam iron in the prior art, through the cooperation of the two electric heating tubes, the double heating reinforcement area is formed at the second half part of the preheating channel. Even if a large amount of steam is continuously generated, the vaporization effect can be ensured, thereby effectively alleviating the risk of dripping water when a large amount of steam is continuously generated.BRIEF DESCRIPTION OF DRAWINGS

[0019] The disclosure will be further described below with reference to the accompanying drawings and examples.
[0020] In the description of the disclosure, it should be understood that, the orientation or positional relationship indicated by the term "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" or the like is based on the orientation or positional relationship shown in the accompanying drawings. This is only for the convenience of describing the disclosure and simplifying the description, and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the disclosure.
[0021] Referring to FIG. 1 to FIG. 4, an example of the disclosure provides an iron unit, including an ironing plate 1 and a first electric heating tube 2. The ironing plate 1 is provided with a preheating channel 11, a heating channel 12 and a steam channel 13 which are sequentially in communication with each other. The first electric heating tube 2 is fixedly mounted on the ironing plate 1 and corresponds to a back of the heating channel 12 in position. The iron unit further includes a second electric heating tube 3. The second electric heating tube 3 is configured to correspond to a back of a second half part of the preheating channel 11 such that a double heating reinforcement area is formed at the second half part of the preheating channel 11. It can be understood that in this example, the ironing plate 1 is provided with the preheating channel 11, the heating channel 12 and the steam channel 13, the ironing plate 1 is further provided with the first electric heating tube 2 and the second electric heating tube 3, and the second electric heating tube 3 is configured to correspond to the back of the second half part of the preheating channel 11. In this way, compared with the steam iron in the prior art, through the cooperation of the two electric heating tubes, the double heating reinforcement area is formed at the second half part of the preheating channel 11. Even if a large amount of steam is continuously generated, the vaporization effect can be ensured, thereby effectively alleviating the risk of dripping water when a large amount of steam is continuously generated.
[0022] Referring to FIG. 1 and FIG. 2, in a preferred example, the first electric heating tube 2 includes two heating tube sections 21 that extend front and rear and are arranged oppositely on the ironing plate 1 left and right. The heating channel 12 includes two diverted heating grooves 121 that extend front and rear and are arranged oppositely on the ironing plate 1 left and right. A middle area generated by an enclosure of the two diverted heating grooves 121 is the preheating channel 11. The two heating tube sections 21 respectively correspond to backs of the two diverted heating grooves 121 in position, and the two diverted heating grooves 121 are both in communication with a rear end of the preheating channel 11.
[0023] Referring to FIG. 1 and FIG. 2, in a preferred example, external influent water is configured to flow into the preheating channel 11 from a front end of the preheating channel 11, and a middle position of a first half part of the preheating channel 11 is formed with a middle bulge structure 111 configured to divert the water in the preheating channel 11 to flow toward left and right sides so as to be close to the two diverted heating grooves 121. It can be understood that in this example, through the middle bulge structure 111 formed at the middle position of the first half part of the preheating channel 11, the influent water in the preheating channel 11 can be effectively diverted to the two sides, such that the water flows closer to the diverted heating grooves 121 at the corresponding sides, thereby improving the preheating efficiency. Moreover, the middle bulge structure 111 can make the temperature of a bottom surface of the ironing plate 1 more uniform.
[0024] Referring to FIG. 1 and FIG. 2 in a preferred example, the steam channel 13 is in communication with front ends of the two diverted heating grooves 121. The steam channel 13 includes two diverted steam grooves 131 that extend front and rear and are arranged oppositely on the ironing plate 1 left and right. The front ends of the two diverted heating grooves 121 are provided with a heating groove communication section 122 for communicating the two diverted heating grooves 121. Front ends of the two diverted steam grooves 131 are in communication with the two diverted heating grooves 121 through the heating groove communication section 122, and the two diverted steam grooves 131 are respectively adjacent to the two diverted heating grooves 121 and extend rearward. The ironing plate 1 is provided with a plurality of steam holes that run up and down through the bottom surface and are in communication with the steam channel 13, and the steam holes are arranged at intervals along an extension direction of the steam channel 13. In addition, the ironing plate 1 is further covered with an adaptive cover 6, and the preheating channel 11, the heating channel 12 and the steam channel 13 are closed by the cover 6.
[0025] Referring to FIG. 1 and FIG. 2, in a preferred example, joints between the preheating channel 11 and the heating channel 12 are provided with multi-step portions 14 going up step by step. Preferably, joints between the multi-step portions 14 and the heating channel 12 are provided with retention grooves 15 for retaining non-vaporized water. In this example, the joints between the preheating channel 11 and the heating channel 12 are provided with the multi-step portions 14 going up step by step, so that the probability of non-vaporized water entering the heating channel 12 is reduced. Further, the joints between the multi-step portions 14 and the heating channel 12 are provided with the retention grooves 15, and the retention grooves 15 can collect the non-vaporized water and retain the non-vaporized water, so that the heating time is increased and the non-vaporized water can be vaporized, thereby preventing liquid water flow flowing out of the iron.
[0026] Referring to FIG. 1 and FIG. 2, in a preferred example, the second electric heating tube 3 has a U-shaped structure. In this example, the second electric heating tube 3 having the U-shaped structure and the first electric heating tube 2 open toward a same direction, and two arms of the second electric heating tube 3 are respectively close to the two diverted heating grooves 121.
[0027] Referring to FIG. 1 and FIG. 2, in a preferred example, the ironing plate 1 is further provided with a first thermostat 4 for controlling the first electric heating tube 2 and a second thermostat 5 for controlling the second electric heating tube 3. Preferably, the first thermostat 4 has a mechanical thermostat structure, and the second thermostat 5 has a temperature-based thermostat structure. In this example, the first electric heating tube 2 and the second electric heating tube 3 are controlled independently by the first thermostat 4 and the second thermostat 5 respectively. In this way, during the steam output period, even if one of the electric heating tubes stops heating under the control of the corresponding thermostat, the other electric heating tube can continue heating without being affected. The double heating tube structure in this example can ensure the generation of a large amount of steam, so that a large amount of steam can be continuously generated, and the steam can be outputted stably.
[0028] Referring to FIG. 1 to FIG. 4, an example of the disclosure further provides a steam iron, including the iron unit according to any of the examples above.
[0029] The above examples are only used to illustrate, but not to limit the technical solution of the disclosure. Although the disclosure has been described in detail with reference to the foregoing examples, it should be understood by those of ordinary skill in the art that they can still make modifications to the technical solution in the above examples or make equivalent replacements on part of the technical features. These modifications or replacements do not make the corresponding technical solution depart from the spirit and scope of the technical solution of the examples of the disclosure. Therefore, all other examples obtained by those of ordinary skill in the art without creative work shall fall into the scope of protection of the disclosure.
