Detailed Description
The first embodiment is as follows:
the present embodiment provides an electric kettle, as shown in fig. 1 and 2, which includes a kettle body and a power base (not shown), wherein the kettle body includes an inner container 1 and a bottom cover 2 disposed below the inner container 1, an installation cavity is formed between the bottom cover 2 and the inner container 1, a temperature controller 3 and a switch assembly 4 connected to the temperature controller 3 are disposed in the installation cavity, the temperature controller 3 includes a housing, an upper coupler 31 disposed on the housing, and a steam sheet 32 communicated with a steam pipe 10, the steam sheet 32 is a bimetal brake, the switch assembly 4 includes a switch bracket 42 and a switch button 41, the switch assembly 4 of the existing electric kettle is generally installed in a direction extending along the steam sheet 32, i.e. the switch button is opposite to the position of the steam sheet 32, and the switch button 41 is provided with an opening at a position, steam can overflow from the opening, at this time, the steam smokes the switch button 41 for a long time, which affects the aesthetic property of the switch button 41, and when the switch button 41 is just boiled or boiling, the consumer may feel too hot by pressing the switch button 41, especially when the switch button is made of metal, which affects the use experience. Therefore, in the embodiment, the arrangement of the switch key 41 and the steam sheet 32 is changed, that is, the switch key does not extend along the radial direction of the upper coupler and the steam sheet, and the position of the switch key 41 relative to the steam sheet 32 is laterally offset by a certain distance, so that the switch key 41 and the steam sheet 32 are not on the same radial axis, thereby achieving the purpose that the switch key 41 and the steam sheet 32 are not arranged in a right-to-right manner, reducing the direct influence of steam on the switch key, and simultaneously reducing the arrangement of a steam box and reducing the cost. Therefore, the extending direction of the switch button 41 and the radial direction of the upper coupler 31 and the steam sheet 32 may be parallel or form a certain angle.
Preferably, in order to facilitate the connection of the switch assembly 4 with the thermostat 3, a first connecting line 61 is formed between the center of the upper coupler 31 and the center of the steam sheet 32, the center of the upper coupler 31 is used as a fixed point, the first connecting line 61 is deflected by 15 degrees to form a second connecting line 62, the first connecting line 61 is deflected by 90 degrees to form a third connecting line 63, the second connecting line 62 and the third connecting line 63 are located on the same side of the first connecting line 61, and the switch button 41 is located between the second connecting line 62 and the third connecting line 63, it can be understood that the second connecting line 62 and the third connecting line 63 can be located on either side of the first connecting line 61, and at this time, the center of the switch button 41 is not located on a vertical plane passing through the first connecting line 61. If the angle is too large, it is inconvenient to connect the switch bracket 42 with the existing thermostat 3, and the related structure of the thermostat 3 needs to be redesigned, for example, a clearance structure is provided, and the change is large. The angle is too small to achieve the purpose of saving space. Further, the angle α between the second line 62 and the third line 63 is 30 to 60 degrees. When the center of the switch button 41 is not at the same level as the first line 61, the second line 62 and the third line 63 in space, the above may mean that the switch button 41 may be projected to pass through a plane area between the second line 62 and the third line 63, that is, the switch button 41 may be partially located between the second line 62 and the third line 63, or may be entirely located between the second line 62 and the third line 63. The above-mentioned connecting line is a ray.
Alternatively, the switch button 41 may be parallel to or not parallel to the extending direction of the steam sheet and the upper coupler, however, in order to make the switch button 41 more beautiful on the kettle body, the switch button 41 is pressed to extend in the radial direction of the upper coupler 31, and it can be understood that the center line of the switch button 41 passes through the center of the upper coupler 31, and here, the center line may be spatially passed, that is, when the center line is not in the same plane with the center of the upper coupler 31, it refers to a vertical line passing through the center of the upper coupler 31.
Based on the change of the structure, the position of the switch button 41 relative to the kettle body can be changed, the switch button 41 is generally arranged right below the handle 8 and can also be arranged on the side of the handle 8, as shown in fig. 8, so that the position of the switch button 41 is more striking, that is, the kettle body further comprises the handle 8 and the spout 51, the handle 8 and the spout 51 are arranged on two sides of the inner container 1 and are arranged oppositely, and the steam sheet 32 is arranged opposite to the handle 8.
