Figure 7 As shown, it includes a reflector and an electric heating tube, and a plurality of "J"-shaped buckles 90 are sleeved on the electric heating tube, and the buckles 90 are fixed to the reflector by self-tapping screws 91. The installation of the self-tapping screws of the existing fixing method of the electric heating tube is relatively inconvenient, and one component requires more self-tapping screws, which is costly. Utility Model Content

[0003] The utility model aims to provide an electric oven reflection plate assembly, which fastens the electric heating tube by twisting the tube buckle end to deform it, thereby facilitating the installation of the electric heating tube, saving self-tapping screws and reducing the cost of the reflection plate assembly.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] An electric oven reflector assembly comprises a reflector and an electric heating tube, wherein the electric heating tube comprises two integrally formed "U"-shaped tube portions and a straight tube portion connecting the two "U"-shaped tube portions;

[0006] The "U"-shaped tube portion and the straight tube portion are each fixed to the reflective plate by at least one tube buckle;

[0007] The tube buckle comprises a circular arc buckling pressing piece and two connecting pieces arranged at both ends of the circular arc buckling pressing piece, and the protruding end of each connecting piece passes through the corresponding rectangular through hole on the reflecting plate and is twisted into a twisted portion.

[0008] During installation, the end of the tube buckle first passes through the corresponding rectangular through hole, and then the arc buckle pressing piece is pressed against and covered on the outer wall of the electric heating tube, and then the end of the connecting piece that passes through the outside of the reflector is twisted, and the twisted part cannot move in the opposite direction along the rectangular through hole, thereby fixing the electric heating tube, thereby avoiding the installation work of self-tapping screws and saving self-tapping screws.

[0009] The utility model is further configured as follows: a plurality of inwardly protruding support protrusions are formed on the inner side wall of the reflecting plate, and the electric heating tubes are abutted against the support protrusions.

[0010] Through the above technical solution, the main body of the reflector plate can be separated from the electric heating tube by a distance through the supporting protrusion, which can reduce the loss of heat transferred by direct contact.

[0011] The utility model is further configured as follows: a plurality of outwardly protruding recesses are formed on the reflective plate; each recess is arranged between two or more corresponding supporting protrusions.

[0012] By providing the recess, the actual distance between the spot heating tube and the reflective plate can be further increased, and the loss of heat transferred by direct contact can be further reduced.

[0013] The utility model is further configured as follows: at least two tube buckles are arranged on one of the "U"-shaped tube parts, and at least two tube buckles are arranged on different direction sections of the "U"-shaped tube part.

[0014] Through the above technical solution, the "U"-shaped tube can be limited in two directions to prevent it from moving arbitrarily.

[0015] The utility model is further configured as follows: a waist-shaped through groove is formed in the middle of the reflector;

[0016] One end of the "U"-shaped tube portion away from the straight tube portion passes through a corresponding waist-shaped through slot and extends to the outside of the reflector plate.

[0017] A waist-shaped through groove is provided to facilitate the passage of one end corresponding to the "U"-shaped pipe portion, and the passed end is used for wiring.

[0018] The outstanding effects of the utility model are:

[0019] Compared with the prior art, the electric heating tube is fastened by twisting the end of the tube buckle to deform it, which can facilitate the installation of the electric heating tube, save self-tapping screws, and reduce the cost of the reflector assembly.

[0031] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0032] The following references Figures 1 to 6 The utility model is described as follows:

[0033] An electric oven reflector assembly includes a reflector 10 and an electric heating tube 20, wherein the electric heating tube 20 includes two integrally formed "U"-shaped tube portions 201 and a straight tube portion 202 connecting the two "U"-shaped tube portions 201;

[0034] The "U"-shaped tube portion 201 and the straight tube portion 202 are each fixed to the reflector 10 by at least one tube buckle 30; a plurality of inwardly protruding support protrusions 102 are formed on the inner side wall of the reflector 10, and the electric heating tube 20 is abutted against the support protrusions 102, and a plurality of outwardly protruding recesses 103 are formed on the reflector 10; each recess 103 is arranged between two or more corresponding support protrusions 102. The main body of the reflector can be separated from the electric heating tube by a distance through the support protrusions and the recesses, which can reduce the loss of heat transfer by direct contact.

[0035] The tube buckle 30 includes a circular arc buckling piece 301 and two connecting pieces 302 arranged at both ends of the circular arc buckling piece 301. The protruding end of each connecting piece 302 passes through the corresponding rectangular through hole 101 on the reflector 10 and is twisted into a twisted portion 303.

[0036] During installation, the end of the tube buckle first passes through the corresponding rectangular through hole, and then the arc buckle pressing piece is pressed against and wrapped around the outer wall of the electric heating tube, and then the end of the connecting piece that passes through the outside of the reflecting plate is twisted and bent. The twisted part cannot move in the opposite direction along the rectangular through hole, thereby fixing the electric heating tube.

[0037] At least two tube buckles 30 are arranged on one of the "U"-shaped tube parts 201, and at least two tube buckles 30 are arranged on different direction sections of the "U"-shaped tube part 201, one is arranged on a section where the "U"-shaped tube part is parallel to the straight tube part, and the other is arranged on a section where the "U"-shaped tube part is perpendicular to the straight tube part. The "U"-shaped tube part can be limited in two directions to prevent it from moving arbitrarily.

[0038] A waist-shaped through groove 104 is formed in the middle of the reflector plate 10;

[0039] One end of the U-shaped tube portion 201 away from the straight tube portion 202 passes through a corresponding waist-shaped through slot 104 and extends to the outside of the reflector 10 .

[0040] A waist-shaped through groove is provided to facilitate the corresponding end of the "U"-shaped tube to pass through, and the passed end is used for wiring.
