Technical solutions of the utility model by outside governor 30 be arranged a fire proofing fire-retardant box 10, and Multiple connection legs of governor 30 are also accommodated in fire-retardant box 10 to be formed by accommodating chamber, when governor 30 is in the course of work In, it is connecting at leg because the melt substance of high temperature is then connected by fire-retardant box 10 without drawing when high temperature generates melt substance The burning for playing household electrical appliances interiors of products other structures, so improves the security performance of household appliances.

Preferably, the material of herein described fire-retardant box 10 is flame retardant silica gel.Flame retardant silica gel is with hydrated alumina, carbon Sour calcium, carbon black and platinum compounds make fire retardant, are configured to anti-flammability silica gel.The average grain diameter of hydrated alumina should 50um with Under, the average grain diameter of calcium carbonate answers 20um hereinafter, acetylene carbon black, thermal black or furnace black, specific surface area can be selected in carbon black It should be greater than 10 ㎡/g, 0.05~0.2um of partial size；Platinum compounds can select platinum/alcohol complex, platinum/vinylsiloxane cooperation Object.Such as Suzhou Xin Wei new high-tech material Co., Ltd brand can be used for SINWE, the white electronic flame-retardant silicon of model 388 Glue integrated injection molding, it is lower with this manufacturing cost, it is easy to produce in enormous quantities, the shape that the side wall 13 of fire-retardant box 10 is surrounded can With rectangular or round or polygonal shape, the global shape of fire-retardant box 10 is structure open at one end.

Further, for the application in order to enable 30 installation process of governor is convenient, the bottom wall 11 is also provided with location hole 19, the side that main part 31 is equipped with adjusting shaft 33 is also convexly equipped with positioning column 37, and positioning column 37 is caught in location hole 19.The application Positioning column 37 includes at least two, and at least two positioning columns, 37 spacer ring is arranged around shaft 33 is adjusted.Wherein positioning column 37 and fixed Position hole 19 is interference fit, and is provided at least two, then when governor 30 is installed to fire-retardant box 10, passes through positioning column 37 insert as to after location hole 19, and mounting structure is firm and to install position fixing process also more convenient.

Further in order to which speed regulator component 100 to be fixed to the casing 210 of frame component, governor 30 also wraps the application Connection boss 39 is included, connection boss 39 with main part 31 there is the side for adjusting shaft 33 to connect, and adjusts 33 activity of shaft and wear Connection boss 39 is crossed, connection 39 outer wall of boss is provided with connection screw thread, and connection boss 39 passes through mounting hole 17 and connecting hole 211 simultaneously It is connect with nut 220 and fire-retardant box 10 is fixedly connected on casing 210.The application abuts the outer wall of casing 210 by nut 220 Fire-retardant box 10 is stretched the inner wall for clinging to casing 210 by face, and entire assembling process is more convenient.

The application is in order to enable the structural strength and flame retardant effect of fire-retardant box 10 are further promoted, speed regulator component 100 It further include the reinforcement structure 20 being fixedly connected with fire-retardant box 10.

Referring to figure 4., in fire-retardant 10 first embodiment of box of the utility model, the reinforcement structure 20 is to attach to be connected to The sheet metal component of 11 outer surface of bottom wall；By attaching sheet metal component in 11 outer surface of bottom wall, so during tightening nut 220, When clamping fire-retardant box 10, fire-retardant box 10 still has biggish structural strength, is not easy to free damage.

Referring to figure 5., in fire-retardant 10 second embodiment of box of the utility model, the reinforcement structure 20 is to attach to be connected to The sheet metal component of the outside wall surface of the bottom wall 11 and the side wall 13；By being provided with sheet metal component in bottom wall 11 and side wall 13, then It is not easy then adding to crack for stress concentration because of the protection of sheet metal component in the junction of bottom wall 11 and side wall 13 While the structural strength of strong fire-retardant box 10, flame retardant effect also increases compared to the scheme of first embodiment.

Fig. 6 is please referred to, in fire-retardant 10 3rd embodiment of box of the utility model, the reinforcement structure 20 is set on bottom wall 11 With the sheet metal component in side wall 13.Sheet metal component can be by pre-buried mode integrated injection molding to fire-retardant box 10, the side of 3rd embodiment The beneficial effect of case and the beneficial effect of second embodiment are similar, and details are not described herein.

Further the application is to promote the structural strength of entire fire-retardant box 10, wherein the wall thickness of bottom wall 11 and side wall 13 Value range is 0.4 millimeter to 1 millimeter.

By foregoing it is found that the side wall 13 of the fire-retardant box 10 of the application has high temperature in connection pin 35 and generates high temperature Melt substance can be connected when falling, to prevent interior other electronics member of high-temperature molten confrontation such as frame component Part or plastics shells carry out structure destruction, thus the security performance of household appliances.On this basis, in order to further be promoted The security performance of household appliances, the application can also be extended with blocking into accommodating chamber in the one end of side wall 13 far from bottom wall 11 and turn over Side (not shown), wherein stopping flange to be located at the outside that connection pin 35 projects immediately below side wall 13, then when connection pin 35 In the case that place has high temperature melt substance to fall, stop flange that can further stop high temperature melt substance opening by fire-retardant box 10 It is tumbled at mouthful, then can further promote the security performance of entire frame component.

The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model, It is all under the inventive concept of the utility model, equivalent structure made based on the specification and figures of the utility model becomes It changes, or directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
