Specific embodiment
In conjunction with referring to shown in Fig. 1 to Fig. 6, according to an embodiment of the invention, a kind of switch block fixed structure is provided, including
Electric appliance casing 1 is configured with arch arm 11, the inside of the arch arm 11 and the electric appliance casing 1 on the inner sidewall of the electric appliance casing 1
The accommodation space that switch block 2 is formed between the corresponding position in face, when the switch block 2 is assembled in the accommodation space
When, the arch arm 11 is capable of fixing the switch block 2.In the technical solution, it is arranged using in 1 inner sidewall of electric appliance casing
Encircle the mode of arm 11, and realize that structure is simple, compact to the fixed function of switch block 2 by arch arm 11, without such as existing skill
Bolt in art like that using greater depth is attached, and can realize the fixation between switch block and shell extremely conveniently
Connection, greatlys improve the packaging efficiency of electric appliance, and more importantly, using the technical solution, make to connect bolt without sudden and violent
It is exposed to the lateral surface of the electric appliance casing 1, so that knob be made to be no longer limited by the screw hole in switch base in size design
Size, without exposure place progress of the corresponding decorative element to screw or head of screw is additionally arranged as in the state of the art
It blocks.
In order to further facilitate the assembling process between the switch block 2 and the electric appliance casing 1, make the switching group
Part 2 more can accurately be positioned at it is described arch arm 11 formed accommodation space within, it is preferable that the electric appliance casing 1 it is interior
Limiting section 12 is also configured on side wall, the limiting section 12 is arranged adjacent to the accommodation space, specifically, for example described limiting section
12 include limit block reinforcement, and the limit block reinforcement is on the inserting path of the switch block 2, at this time can be by the switching group
Part 2 using inserting by the way of be inserted into the accommodation space, since the limit block reinforcement is in the inserting of the switch block 2
On path, thus, it is only required to limit the relative position between the limit block reinforcement and the arch arm 11, it can realize to described
Positioning of the switch block 2 on cartridge insertion direction.
The arch arm 11 can for example use relatively simple cantilever design, but cantilever design is due to having a freedom
End, on fatigue resistance in place of Shortcomings, it is preferred, therefore, to the arch arm 11 is designed as portal-framed structure, it is described
The both ends of portal-framed structure are connect with the inner sidewall of the electric appliance casing 1, and it is understood that when the switch block 2 is in
When in the accommodation space, the portal-framed structure will form the switch block 2 and encircle effect, especially itself and limit above-mentioned
The accommodation space of the switch block 2 is collectively formed in position block reinforcement, keeps structure fixation relatively reliable.Further, outside the electric appliance
Switch block supporting table 13 is also configured on the inner sidewall of shell 1, specifically, for example, the switch block supporting table 13 can be only
It stands on the arch arm 11 and is arranged on the inner sidewall of the electric appliance casing 1, and it is preferred that the switch block supporting table 13
Junction between inner sidewall in the portal-framed structure and the electric appliance casing 1 is realizing it to the switch block 2
The design of portal-framed structure can also be optimized while support.
The arch arm 11 can be various ways to the fixed form of the switch block 2, for example, by the arch
The mode of snap-on is set on arm 11, only needs to be correspondingly arranged corresponding wedge slot, this certain energy of mode at this time on switch block 2
Enough convenient connections for realizing switch block 2 and electric appliance casing 1, but there is also its shortcomings for this mode, for example, it is needed
The special designing of switch block 2, and for the applicability of current existing switch block 2, there are certain deficiencies, therefore, more have
It is sharp, through-hole 111 is formed on the arch arm 11, the arch arm 11 is connected by the through-hole 111 with the switch block 2
It connects.
Specifically, connector is connected to by 111 pushing tow of through-hole for example, the inner wall of the through-hole 111 has screw thread
On the switch block 2, namely the fixed jacking force by the connector of the switch block 2 is clamped, the connection
Part for example can be bolt；And/or the switch block 2 has threaded hole 212 corresponding with the through-hole 111, the arch
Arm 11 is bolted by the through-hole 111 with the switch block 2.
Further, the switch block 2 includes switch base 21 and the knob 22 being detachably connected with it, the electricity
The placement configurations corresponding with the arch arm 11 of device shell 1 have knob to walk hole 14.The switch base 21 has and the rotation
The rotary shaft 211 of 22 grafting of button, the knob 22 have the axle sleeve 221 to socket-connect with the rotary shaft 211.The rotary shaft
211 section is arbitrarily adapted to and is formed the shape of reliable stop bit in D type or rectangular, triangle etc., the axle sleeve 221 it is interior
The section of pore structure and the rotary shaft 211 is adapted.Preferably, the inner hole that the cambered surface part in D type section and axle sleeve 221 have
Hole wall cambered surface part fits, and the inner hole hole wall planar section that the planar section of D type then has with axle sleeve 221 fits, and makes
Combination between rotary shaft 211 and axle sleeve 221 is relatively reliable, and anti-twisting property with higher.
In addition, the knob 22 also has knob shell 222, the knob shell 222 and the electric appliance casing 1 are rotatable
Connection.Preferably, the outer rim that the knob walks hole 14 is formed with circumference flange 15, the knob shell 222 and the axle sleeve
Multiple elastic clamping hooks 223 are configured between 221, when the knob 22 is assembled with the electric appliance casing 1, multiple elastic cards
Hooking 223 can be with 15 snapping of circumference flange.Using this kind of structure, the switch block fixed structure can be significantly improved
Waterproof performance.
In order to improve the aesthetic appearance of the knob 22, further, in the knob 22 towards the end of user side
Decorative panel is provided on face.
According to an embodiment of the invention, a kind of electric appliance is also provided, including above-mentioned switch block fixed structure, the electric appliance
It such as can be electric heater, wall-hung boiler etc..
Those skilled in the art will readily recognize that above-mentioned each advantageous manner can be free under the premise of not conflicting
Ground combination, superposition.
The above is merely preferred embodiments of the present invention, be not intended to limit the invention, it is all in spirit of the invention and
