Description

Cooking appliances

[0001] The present disclosure relates to a cooking appliance including a magnetron.

[0002] Magnetrons generate powerful high-frequency waves by controlling the flow of electrons through the application of a magnetic field, and are used in high-frequency heating devices such as microwave ovens.

[0003] To install a magnetron in a microwave oven, a bracket is typically used to secure the magnetron. Screws and other devices may be used to secure or secure the magnetron, and these should be minimized for manufacturing processes and cost reduction.

[0004] At the same time, the fixing force between the bracket and the magnetron must be sufficiently secured to prevent the magnetron from coming off during the movement of the microwave oven.

[0005] A cooking appliance is provided in which a magnetron is easily mounted on a bracket.

[0006] A cooking appliance is provided in which a magnetron is mounted on a bracket without a separate fastening member.

[0087] Referring to FIGS. 4 to 9, the magnetron (100) can be mounted on a bracket (200).

[0088] The magnetron (100) may include a plurality of coupling pieces (171, 172, 173, 174) formed on one side of the yoke (110). A fixing hole (171a, 172a, 173a, 174a) may be formed in each of the plurality of coupling pieces (171, 172, 173, 174). As shown in the present illustration, the plurality of coupling pieces (171, 172, 173, 174) may be formed in two on each side, but is not limited thereto, and may be formed in one on each side.

[0089] A plurality of connecting pieces (171, 172, 173, 174) can be formed by extending a predetermined length from the yoke (110). Specifically, a plurality of connecting pieces (171, 172, 173, 174) can be formed by extending a predetermined length from the yoke cover (112).

[0090] The plurality of coupling pieces (171, 172, 173, 174) may include a first coupling piece (171) provided on one side of the magnetron (100) and a second coupling piece (172) provided on the other side of the magnetron (100). In other words, the plurality of coupling pieces (171, 172, 173, 174) may include a first coupling piece (171) provided on one side of the magnetron (100) and a second coupling piece (172) provided on the opposite side of the first coupling piece (171).

The first connecting piece (171) and the second connecting piece (172) and the third connecting piece (173) and the fourth connecting piece (174) may be provided symmetrically to each other.

[0092] In addition, the plurality of coupling pieces (171, 172, 173, 174) may include an upper coupling piece (171, 173) provided on the upper side of the magnetron (100) and a lower coupling piece (172, 174) provided on the lower side of the magnetron (100).

[0097] The bracket (200) may include a bracket body (201) in which an antenna hole (200a) is formed. The bracket body (201) may have a roughly plate shape. The bracket body (201) may be a portion with which the magnetron (100) comes into contact.

[0098] The bracket body (201) may be arranged to allow the magnetron (100) to be mounted thereon. Specifically, the yoke cover (112) of the magnetron (100) may be positioned to be in contact with the bracket body (201).

[0099] The bracket (200) may include a mounting portion (202) formed by bending from the bracket body (201). The mounting portion (202) may be supported on the upper side of the inner case (20). The mounting portion (202) may be provided so that the bracket (200) comes into contact with the waveguide (23, see FIG. 3). Specifically, when the magnetron (100) is mounted on the bracket (200), the output portion (170) may be positioned within the waveguide (23). The bracket (200) may mediate the coupling between the waveguide (23) and the magnetron (100).

[0100] It may include a support member (211) provided to support a plurality of connecting pieces (171, 172, 173, 174).

[0101] A support member (211) may be provided to mount a magnetron (100). Specifically, a yoke (110) may be fixed to the support member (211). At least some of the plurality of coupling pieces (171, 172, 173, 174) of the yoke (110) may be supported by the support member (211). For example, as shown in the present illustration, a first coupling piece (171) may be supported by the support member (211).

[0102] The support portion (211) can be formed by lancing the bracket body (201). Specifically, the support portion (211) can be formed by cutting a portion of the bracket body (201) and pressing and bending the cut portion.

[0103] The support member (211) may be formed to correspond to at least one of the plurality of connecting pieces (171, 172, 173, 174). In the present invention, the support member (211) is provided to be mounted with the first connecting piece (171), and therefore may be formed at a position corresponding to the first connecting piece (171).

[0104] A bead (231) may be formed on the support member (211). The bead (231) may have a roughly hemispherical shape. However, the shape of the bead (231) is not limited thereto. For example, the bead (231) may be formed in various shapes, such as a square or a triangle.

[0105] The support member (211) may include a bead forming surface (2111) on which a bead (231) is formed.

[0106] The bead forming surface (2111) may be provided parallel to the bracket body (201). A first coupling piece (171) may be inserted between the bead forming surface (2111) and the bracket body (201). As the first coupling piece (171) is inserted, a bead (231) may be inserted into a first coupling hole (171a) formed in the first coupling piece (171). Accordingly, the bead (231) may protrude from the bead forming surface (2111) toward the bracket body (201).

[0107] The support member (211) may include a movement restriction surface (2112) that is bent from the bead forming surface (2111).

[0108] The movement restriction surface (2112) can prevent the first coupling piece (171) mounted on the support member (211) from being disengaged from the coupling position. The movement restriction surface (2112) can be formed in a direction other than the direction in which the first coupling piece (171) is inserted. That is, the movement restriction surface (2112) can be formed so that one side into which the first coupling piece (171) is inserted is open. In addition, the movement restriction surface (2112) can be formed so as to surround the first coupling piece (171) when the first coupling piece (171) is mounted.

[0109] The bracket (200) may include a support slot (220). The support slot (220) may include a support slot (221, 222) provided to support the lower connecting piece (172, 174).

[0110] The support slots (221, 222) may be provided so that the lower coupling pieces (172, 174) are inserted. The support slots (221, 222) may include a first support slot (221) provided to support the first lower coupling piece (172), and a second support slot (222) provided to support the second lower coupling piece (174).

[0111] The support slot (221, 222) may include an inclined surface (2212, 2222) in which a portion of the support slot (221, 222) is formed inclined so that the lower connecting piece (172, 174) is inserted inclinedly.

[0112] Referring to FIGS. 7 to 9, a method of mounting a magnetron (100) on a bracket (200) will be described.

[0113] In order for the magnetron (100) to be mounted on the bracket (200), the first upper coupling piece (171) may be configured so as not to interfere with the support (211). Specifically, when the lower coupling pieces (172, 174) are inserted into the support slots (221, 222), the first upper coupling piece (171) may interfere with the support (211). Accordingly, when the lower coupling pieces (172, 174) are inserted into the support slots (221, 222) at an angle, the first upper coupling piece (171) can avoid the support (211).

[0114] The first upper coupling piece (171) can be inserted into the open side of the support part (211). Therefore, the first upper coupling piece (171) can be positioned to be inclined toward the open side of the support part (211). Since the upper coupling pieces (171, 173) and the lower coupling pieces (172, 174) are provided symmetrically to each other, the lower coupling pieces (172, 174) can also be positioned to be inclined in the same direction as the first upper coupling piece (171). That is, the inclined surfaces (2212, 2222) provided to allow the lower coupling pieces (172, 174) to move along can also be inclined toward the open side of the support part (211).

[0115] After the lower connecting piece (172, 174) is inserted into the support slot (221, 222) at an angle, the first upper connecting piece (171) can be rotated toward the support part (211) with the lower connecting piece (172, 174) as the rotation axis. The first upper connecting piece (171) can be inserted into the open side of the support part (211) while being rotated.

[0116] The support member (211) can be elastically deformed while the magnetron (100) is mounted on the bracket (200). The first coupling member (171) of the magnetron (100) can press the bead (231) protruding toward the bracket body (201) and the bead forming surface (2111) on which the bead (231) is formed when the support member (211) is inserted.

[0117] The bead forming surface (2111) can be pressed in a direction opposite to the protrusion direction of the bead (231). That is, the support portion (211) can be elastically deformed in a direction in which the gap between the bead forming surface (2111) and the bracket body (201) increases.

[0118] The support member (211) can be elastically restored when the magnetron (100) is mounted on the bracket (200). When the first coupling piece (171) of the magnetron (100) is mounted on the support member (211), a bead (231) can be inserted into the fixing hole (171a) of the first coupling piece (171). In this way, the support member (211) can be elastically restored when the pressurized state of the bead (231) is released.

[0119] The angle of inclination (θ) formed by the inclined surface (2212) and the movement restriction surface (2211) of the support slot (221) may be approximately 10 degrees. Specifically, the angle of inclination (θ) may be approximately 5 to 15 degrees. However, the size of the angle of inclination (θ) is not limited thereto, and any angle may be provided as long as interference does not occur between the first upper connecting piece (171) and the support portion (211).

[0120] Referring again to FIG. 5, the magnetron (100) can be mounted on the support slots (221, 222) and the support member (211) of the bracket (200). When the magnetron (100) is mounted on the bracket (200), the fixing hole (173a) formed on the second upper connecting piece (173) and the fastening hole (201a) formed on the bracket body (201) can be positioned to correspond to each other.

[0121] The magnetron (100) and the bracket (200) can be fastened through a fastening member (300) to ensure a stronger connection. The fastening member (300) can be fastened by being inserted into the fixing hole (173a) and the fastening hole (201a).

[0122] The fastening member (300) may be provided as a bolt. However, the type of the fastening member (300) is not limited thereto, and may be provided in various forms such as a pin or rivet.

[0123] In this way, the magnetron (100) according to the embodiment of the present disclosure can be mounted on the bracket (200) without the fastening member (300). Alternatively, the magnetron (100) can be mounted on the bracket (200) using only one fastening member (300).

[0124] By means of the bracket (200) according to the embodiment of the present disclosure, the number of required fastening members (300) can be reduced, thereby reducing cost and increasing production efficiency.
