Description

Technical Field

[0001] The invention belongs to the ironing technology, and in particular relates to an ironing soleplate and a steam electric iron capable of preventing water from dripping. Background Art

[0002] As is known, a steam iron utilizes an ironing soleplate to heat water and convert it into steam, and then releases the steam from the ironing soleplate for ironing.

[0003] In the process of converting water into steam and releasing steam, there is a phenomenon that the steam contains water droplets, which causes dripping and affects the ironing effect. In addition, the water droplets are prone to contain foreign matter and contaminate the clothes.

[0004] The invention patent application with application publication number CN106605020A discloses a steam iron head. The steam iron head has a steam inlet, a steam channel and at least one steam outlet, and steam is discharged from the steam iron head through the steam outlet. The steam channel has a first steam flow section and a second steam flow section. The first steam flow section defines an indirect flow path between the steam inlet and the second steam flow section. The second steam flow section defines a cyclonic flow path between the first steam flow section and the at least one steam outlet. It is helpful to remove any water droplets, such as water droplets formed by condensation, from the steam flow passing through the steam iron head from the steam inlet to the at least one steam outlet.

[0005] However, in the above-mentioned steam iron head, the steam formed from the steam chamber flows through a short path when discharged through the steam outlet, and the steam is not heated sufficiently. The steam temperature is low and it is easy to carry small water droplets, resulting in poor ironing effect and low efficiency. Summary of the invention

[0006] The technical problem to be solved and the technical task proposed by the present invention are to overcome the defects of the existing steam iron head, that is, the steam formed in the steam chamber has a short flow path when discharged through the steam outlet, the heating is not sufficient, the steam temperature is low and it is easy to carry small water droplets, and to provide an ironing soleplate and a steam electric iron.

[0007] To achieve the above-mentioned purpose, the ironing soleplate of the present invention comprises a soleplate and a cover, wherein an isolated steam chamber and a steam exhaust chamber are formed between the soleplate and the cover, wherein the steam chamber has a water inlet, and the steam exhaust chamber has an exhaust hole arranged on the soleplate, and is characterized in that the steam chamber and the steam exhaust chamber are connected via a steam passage connected therebetween.

[0008] As a preferred technical means: the vapor passage and the exhaust chamber are arranged in layers, and the vapor passage is located on the upper side of the exhaust chamber.

[0009] As a preferred technical means: the vaporization channel and the exhaust chamber are separated by a partition.

[0010] As a preferred technical means: the partition is sealed by interference fit or edge close contact to isolate the vapor passage from the exhaust chamber.

[0011] As a preferred technical means: a platform is provided at the boundary between the vaporization channel and the exhaust chamber, and the partition is attached to the platform to achieve sealing and isolate the vaporization channel from the exhaust chamber.

[0012] To achieve the above object, the steam iron of the present invention is equipped with the ironing soleplate of the present invention.

[0013] The vaporization chamber and the steam exhaust chamber of the present invention are connected via a vaporization channel connected therebetween, so that after water is converted into steam in the vaporization chamber, it does not directly enter the steam exhaust chamber, but first flows through the vaporization channel and then enters the exhaust chamber, thereby extending the path of the steam from the vaporization chamber into the steam exhaust chamber, so that the tiny water droplets contained in the steam can be fully vaporized, and at the same time the steam can be fully heated to increase the steam temperature, thereby improving the ironing effect and efficiency of the steam iron, saving time and effort for users, and having a simple structure and very low cost.

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] like Figure 1-4 The ironing soleplate shown comprises a soleplate 100 and a cover 200 .

[0028] The bottom plate 100 is generally made of aluminum alloy die-casting, and includes an electric heating pipe 700 for heating the entire bottom plate. There is also a PTC thermistor configured on the bottom plate to provide heat for the bottom plate. The bottom plate 100 is provided with an inner wall 101 and an outer wall 102 extending upward. The inner wall 101 determines the boundary of the vaporization cavity 300. In order to increase the vaporization effect, the surface of the bottom plate corresponding to the vaporization cavity is provided with a protrusion to increase the contact area with water. The vaporization cavity is formed into a maze shape by the isolation ribs 104 arranged therein to increase the vaporization path. A groove is formed between the inner wall and the outer wall, and an exhaust hole 103 is provided on the bottom surface of the groove. A partition plate 600 is horizontally installed in the groove, and a vapor flow channel 500 connected to the vapor chamber is formed on the upper side of the partition plate, and an exhaust chamber 400 is formed on the lower side of the partition plate. The vapor channel 500 and the exhaust chamber 400 are stacked and arranged. The vapor channel 500 is located on the upper side of the exhaust chamber 400, and the rear end of the vapor channel 500 is connected to the vapor chamber 300, and the front end of the vapor channel 500 is connected to the exhaust chamber 400, so that the airflow directions in the exhaust chamber and the vapor channel are opposite. This opposite flow direction is Figure 3 The vaporization channel 500 and the exhaust chamber 400 are located outside the vaporization chamber 300, and the height of the vaporization channel and the exhaust chamber stacked together is determined by the height of the inner wall 101 to be consistent with the height of the vaporization chamber.

[0029] The cover 200 is generally made of a metal sheet by die-pressing. It is sealed and assembled on the upper side of the bottom plate 100, and covers the vaporization chamber 300, the vaporization flow channel 500, and the exhaust chamber 400. Thus, an isolated vaporization chamber 300 and an exhaust chamber 400 are formed between the bottom plate 100 and the cover 200. The vaporization chamber has a water inlet. The water inlet 201 is generally arranged on the cover 200 and corresponds to the starting position of the vaporization chamber, so that the water entering the vaporization chamber can have a longer vaporization path. The vaporization chamber and the exhaust chamber are connected through the vaporization channel 500 connected therebetween. When working, water is input into the vaporization chamber 300 through the water inlet 201, and the water is converted into steam in the vaporization chamber, and then flows into the exhaust chamber 400 through the vaporization channel 500, and finally flows out from the exhaust hole 103. Since the steam generation channel is added, the path of the steam from the steam generation chamber into the steam exhaust chamber is extended, so that the steam can be fully heated, and the tiny water droplets contained in the steam can be fully vaporized. At the same time, the steam can be fully heated to increase the steam temperature, thereby improving the ironing effect and efficiency of the steam iron, saving time and effort for users, and the structure is simple and the cost is very low.

[0030] The edge of the partition 600 is in interference fit with the inner wall 101 and the outer wall 102 or the edge is in close contact with each other to achieve sealing and isolate the vapor passage from the exhaust chamber. In specific implementation, a platform can also be provided on the inner wall 101 and the outer wall 102 at the boundary between the vapor passage and the exhaust chamber, and the partition is attached to the platform to achieve sealing and isolate the vapor passage from the exhaust chamber.

[0031] In particular, the vaporization passage and the exhaust chamber are symmetrically arranged on the outer side of the vaporization chamber, and the exhaust chambers symmetrically arranged on the left and right are connected at the front ends thereof, so that the steam output is uniform.

[0032] In view of the above-mentioned structure of the ironing soleplate, it can be applied to steam electric irons of various structural forms, and the predetermined effect can be achieved regardless of whether the water tank is arranged on the electric iron itself or on the base configured for the electric iron.
