Ironing panel and ironing device

Abstract

An ironing panel and an ironing device are related to clothes ironing appliances. The temperature distribution of existing ironing panels is non-uniform during ironing. The ironing panel of the invention comprises a panel body provided with a patch having a patch ironing surface, the patch ironing surface and a main ironing surface are continuous to form a complete ironing surface, and a gap is reserved between the patch and the panel body to form a heat homogenizing cavity. When the ironing panel works, an electric heater transfers heat to the panel body, the main ironing surface away from the electric heater is maintained at a low temperature, and heat from the electric heater is indirectly transferred to the patch ironing surface via the main ironing surface and the heat homogenizing cavity rather than being directly transferred to the patch ironing surface.

4. The ironing panel according to claim 1, wherein a steam channel allowing steam to enter the heat homogenizing cavity is formed in the panel body, and steam holes for discharging the steam are formed in the patch.

5. An ironing device, comprising the ironing panel according to claim 1.

6. The ironing device according to claim 5, wherein a steam generation cavity is formed in a side, backing onto the ironing surface, of the ironing panel, and is communicated with the heat homogenizing cavity via the steam channel.

7. The ironing device according to claim 5, wherein the ironing device is an electric iron, and the ironing panel is used as an iron base plate.

8. The ironing device according to claim 5, wherein the ironing device is a steam brush, and the ironing panel is used as a steam discharge panel of the steam brush.

DETAILED DESCRIPTION OF THE INVENTION

(17) The invention will be further described below in conjunction with the accompanying drawings in the specification.

(18) As shown in FIG. 1-FIG. 2, an ironing panel 100 comprises a panel body 110 and an electric heater 120 for supplying heat to the panel body, wherein the panel body 110 has a main ironing surface 111 for ironing clothes, and is provided with a patch 130 having a patch ironing surface 131, the patch ironing surface 131 and the main ironing surface 111 are continuous to form a complete ironing surface, the continuity of the patch ironing surface 131 and the main ironing surface 111 means that a continuous ironing surface is formed by the patch ironing surface 131 and the main ironing surface 111, the continuous ironing surface may be a plane or a curved surface, a gap 140 is reserved between the patch 130 and the panel body 110 to form a heat homogenizing cavity, steam channels allowing steam to enter the heat homogenizing cavity are formed in the panel body, and steam holes 132 for discharging steam are formed in the patch. In specific implementation, the steam holes 132 may be formed in the main ironing surface 111, and the steam channels are communicated with the steam holes and are not necessarily communicated with each other.

(19) In specific implementation, the gap 140 forming the heat homogenizing cavity is 1-5 mm. The patch 130 is located in the middle of the main ironing surface 111. The electric heater 120 is an electric heating tube buried in the panel body. The electric heater corresponds to the heat homogenizing cavity, and the heat homogenizing cavity is isolated from the patch.

(20) When the ironing panel works, the electric heater transfers heat to the panel body 110, and the main ironing surface 111 away from the electric heater is maintained at a low temperature; although the patch ironing surface 131 is close to the electric heater, the electric heater is unable to directly transfer heat to the patch ironing surface due to the existence of the heat homogenizing cavity, and heat from the electric heater is indirectly transferred to the patch ironing surface via the main ironing surface and the heat homogenizing cavity, such that the temperature of the patch ironing surface is kept identical with the temperature of the main ironing surface, which makes the temperature distribution of the whole ironing surface uniform, thus improving the ironing efficiency and the ironing effect.

(21) Wherein, the patch is fixed on the panel body preferably by welding or bonding.

(22) As shown in FIG. 4, when the electric heater generates heat and steam is not generated (dry ironing), the temperature distribution on the ironing surface is in the form of closed lines 150 shown in FIG. 4, and the closed lines in FIG. 4 are uniformly distributed, which indicates that the temperature distribution of the whole ironing surface is uniform. As shown in FIG. 5, when the electric heater generates heat and steam is generated (wet drying), the temperature distribution on the ironing surface is in the form of closed lines 150 shown in FIG. 4, and the closed lines in FIG. 5 are distributed uniformly, which indicates that the temperature distribution of the whole ironing surface is uniform. It can be known, by comparing the closed lines in FIG. 4 with the closed lines in FIG. 5, that the density of the closed lines in FIG. 4 is greater than that of the closed lines in FIG. 5, which indicates that the temperature of the ironing surface during dry ironing is higher than the temperature of the ironing surface during wet ironing when the electric heater works under the same condition.

(23) The ironing panel is applied to an ironing device. When applied to an electric iron 200 shown in FIG. 3, the ironing panel is used as an iron base plate. A steam generation cavity is formed in a side, backing onto the ironing surface, of the ironing panel, and is communicated with the heat homogenizing cavity via the steam channels. When steam needs to be generated, water is converted into steam in the steam generation cavity, and then the steam enters the heat homogenizing cavity via the steam channels and is finally discharged via the steam holes to be used for ironing. The steam in the heat homogenizing cavity can also transfer heat to ensure that the temperature distribution of the whole base plate is uniform during wet ironing.

(24) In specific implementation, the ironing device may be a steam brush, and in this case, the ironing panel is used as a steam discharge panel of the steam brush.
