Description

TECHNICAL FIELD

The present disclosure relates to a cooking appliance including a magnetron.

BACKGROUND ART

Magnetrons generate strong high-frequency waves by controlling the flow of electrons by applying a magnetic field and are used in high-frequency heating devices such as microwave ovens.

In order to install a magnetron in a microwave oven, a method of coupling the magnetron to a bracket is used. Screws and the like may be used to fix or fasten the magnetron, but there is a need to minimize the use thereof in terms of simplification of manufacturing processes and reduction in manufacturing costs.

At the same time, a sufficient fixing force between the bracket and the magnetron needs to be obtained to prevent the magnetron from being separated therefrom while a microwave oven is moved.

Referring to FIGS. 4 to 9, the magnetron 100 may be mounted on the bracket 200.

The magnetron 100 may include a plurality of couplers 171, 172, 173, and 174 formed at one side of the yoke 110. Fixing holes 171a, 172a, 173a, and 174a may be formed respectively in the plurality of couplers 171, 172, 173, and 174. As shown in the drawings, the plurality of couplers 171, 172, 173, and 174 may be formed in two on each of the opposite sides, but the embodiment is not limited thereto, and the couplers may be formed in one on each side.

The plurality of couplers 171, 172, 173, and 174 may be formed by extending from the yoke 110 by a predetermined length. Specifically, the plurality of couplers 171, 172, 173, and 174 may be formed by extending from the yoke cover 112 by a predetermined length.

The plurality of couplers 171, 172, 173, and 174 may include a first coupler 171 provided at one side of the magnetron 100 and a second coupler 172 provided at the other side of the magnetron 100. In other words, the plurality of couplers 171, 172, 173, and 174 may include a first coupler 171 provided at one side of the magnetron 100 and a second coupler 172 provided at the other side opposite to the first coupler 171.

The lower couplers 172 and 174 may include a first lower coupler 172 provided symmetrically to the first upper coupler 171 and a second lower coupler 174 provided symmetrically to the second upper coupler 173.

The yoke 110 may include the first coupler 171 formed at one side and the second coupler 172 formed the other side opposite to the first coupler 171. The first coupler 171 and the second coupler 172 may extend in opposite directions.

The bracket 200 may include a bracket body 201 in which an antenna hole 200a is formed. The bracket body 201 may have an approximate plate shape. The bracket body 201 may be in contact with the magnetron 100.

The bracket body 201 may be provided to seat the magnetron 100 thereon. Specifically, the yoke cover 112 of the magnetron 100 may be arranged to be in contact with the bracket body 201.

The bracket 200 may have a mount 202 bent from the bracket body 201. The mount 202 may be supported by the upper side of the inner case 20. The mount may be provided such that the bracket 200 is in contact with the waveguide 23 (See FIG. 3). Specifically, in the state where the magnetron 100 is mounted on the bracket 200, the output device 170 may be located in the waveguide 23. The bracket 200 may mediate the coupling of the waveguide 23 to the magnetron 100.

The bracket 200 may include a support 211 provided to support the plurality of couplers 171, 172, 173, and 174.

The support 211 may be provided to install the magnetron 100. Specifically, the yoke 110 may be fixed to the support 211. At least some of the plurality of couplers 171, 172, 173, and 174 of the yoke 110 may be supported by the support 211. For example, as shown in the drawings, the first coupler 171 may be supported by the support 211.

The support 211 may be formed by lancing the bracket body 201. Specifically, the support 211 may be formed by partially cutting the bracket body 201 and bending the cut portion by pressing.

The support 211 may be formed to correspond to at least one of the plurality of couplers 171, 172, 173, and 174. Because the support 211 is provided to install the first coupler 171 herein, the support 211 may be formed at a position corresponding to the first coupler 171.

A bead 231 may be formed at the support 211. The bead 231 may have an approximate hemisphere shape. However, the shape of the bead 231 is not limited thereto. For example, the bead 231 may be provided to have various shapes such as a triangle and a quadrangle.

The support 211 may include a bead-forming surface 2111 on which the bead 231 is formed.

The bead-forming surface 2111 may be provided to be parallel to the bracket body 201. The first coupler 171 may be inserted between the bead-forming surface 2111 and the bracket body 201. As the first coupler 171 is inserted, the bead 231 may be inserted into the first coupling hole 171a formed in the first coupler 171. Therefore, the bead 231 may protrude toward the bracket body 201 from the bead-forming surface 2111.

The support 211 may include a movement-limiting surface 2112 bent from the bead-forming surface 2111.

The movement-limiting surface 2112 may prevent the first coupler 171 mounted on the support 211 from deviating from a coupling position. The movement-limiting surface 2112 may be formed in a direction other than a direction in which the first coupler 171 is inserted. That is, the movement-limiting surface 2112 may be formed with one open side into which the first coupler 171 is inserted. In addition, the movement-limiting surface 2112 may be formed to surround the first coupler 171 when the first coupler 171 is installed.

The bracket 200 may include support slots 221 and 222 provided to support the lower couplers 172 and 174.

The support slots 221 and 222 may be provided to allow the lower couplers 172 and 174 to be inserted thereinto. The support slots 221 and 222 may include a first support slot 221 provided to support the first lower coupler 172 and a second support slot 222 provided to support the second lower coupler 174.

The support slots 221 and 222 may include slopes 2212 and 2222 formed by partially inclining the support slots 221 and 222 to allow the lower couplers 172 and 174 to be slantly inserted thereinto.

Referring to FIGS. 7 to 9, a method of mounting the magnetron 100 on the bracket 200 will be described.

To mount the magnetron 100 on the bracket 200, the first upper coupler 171 may be configured not to be interfered with by the support 211. Specifically, while the lower couplers 172 and 174 are inserted into the support slots 221 and 222, the first upper coupler 171 may be interfered with by the support 211. Therefore, by slantly inserting the lower couplers 172 and 174 into the support slots 221 and 222, the first upper coupler 171 may avoid the support 211.

The first upper coupler 171 may be inserted into the open side of the support 211. Therefore, the first upper coupler 171 may be located to be slanted toward the open side of the support 211. Because the upper couplers 171 and 173 area arranged symmetrically to the lower couplers 172 and 174, the lower couplers 172 and 174 may also be located to be slanted in the same direction as that of the first upper coupler 171. That is, the slopes 2212 and 2222 along which the lower couplers 172 and 174 move may also be slanted toward the open side of the support 211.

After the lower couplers 172 and 174 are slantly inserted into the support slots 221 and 222, the first upper coupler 171 may rotate about the lower couplers 172 and 174, as rotation shafts, toward the support 211. While rotating, the first upper coupler 171 may be inserted into the open side of the support 211.

While the magnetron 100 is mounted on the bracket 200, the support 211 may be elastically deformed. While being inserted into the support 211, the first coupler 171 of the magnetron 100 may press the bead 231 protruding toward the bracket body 201 and the bead-forming surface 2111 on which the bead 231 is formed.

The bead-forming surface 211 may be pressed in a direction opposite to the protruding direction of the bead 231. That is, the support 211 may be elastically deformed in a direction where a gap between the bead-forming surface 2111 and the bracket body 201 widens.

After the magnetron 100 is mounted on the bracket 200, the support 211 may be elastically restored. When the first coupler 171 of the magnetron 100 is coupled to the support 211, the bead 231 may be inserted into the fixing hole 171a of the first coupler 171. As such, the pressed state of the bead 231 is released so that the support 211 may be elastically restored.

A tilt angle (θ) between the slope 2212 and the movement-limiting surface 2211 of the support slot 221 may be about 10°. Specifically, the tilt angle (θ) may be about 5° to about 15°. However, the tilt angle (θ) is not limited thereto and may be any angle as long as there is no interference between the first upper coupler 171 and the support 211.

Referring back to FIG. 5, the magnetron 100 may be coupled to the support slots 221 and 222 and the support 211 of the bracket 200. After the magnetron 100 is mounted to the bracket 200, the fixing hole 173a formed in the second upper coupler 173 may be located to correspond to the fastening hole 201a formed in the bracket body 201.

The magnetron 100 may be fastened to the bracket 200 by the fastening member 300 for stronger coupling therebetween. The fastening member 300 may be inserted into the fixing hole 173a and the fastening hole 201a for fastening.

The fastening member 300 may be provided as a bolt. However, the type of the fastening member 300 is not limited thereto and the fastening member 300 may be provided in various forms such as a pin or a rivet.
