Description

  The present invention relates to an electric roaster.

  The electric roaster is a device that includes a heater and a cooking plate in the main body, and cooks foods such as meat, seafood, and vegetables with the cooking plate by turning on the power and heating the heater.

  A conventional electric roaster is, for example, described in Korean Patent Publication No. 10-2017-0094611. Usually, as described in Korean Patent Publication No. 10-2017-0094611, the electric roaster is formed long on one side and has a rectangular shape in plan view, and the power supply unit is provided on the short side of the main body. It is provided in the center in parallel to the longitudinal center line.

  A cooking plate is provided in the cooking space enclosed by the side wall of the main body, and each side wall is formed higher than the upper surface of the cooking plate. In order to secure a space for cooking food as much as possible, the cooking plate is generally formed as large as possible within a range limited to the extent that the cooking plate is in close contact with the side wall.

Korean Patent Publication No. 10-2017-0094611

  Since the electric roaster having such a structure is provided with a power supply unit in the center of one short side surface, the size of the cooking plate is limited in consideration of the length of the entire apparatus including the power supply unit. In order to make the cooking plate longer, it is necessary to lengthen the entire length of the electric roaster, which not only increases the cost of the product but also causes inconvenience in use and storage.

  Further, depending on the position of the power supply unit and the side wall of the main body and the structure of the cooking plate, there is no handle of the cooking plate, or a separate member can be used to extend and contract vertically to the edges on both sides in the longitudinal direction of the cooking plate. A handle is provided. In order to provide a handle with such a structure, the edge of the cooking plate needs to be large enough to secure enough space, which can be another limitation in securing cooking space. Furthermore, since such a handle is easily heated by heat during cooking and often contaminated with food, there is a problem that it is difficult to lift the cooking plate from the main body during cooking.

  In the case of a conventional air circulation type electric roaster, the power supply part is provided in the center in the short direction in parallel with the center line of the main body, so depending on the distance between the power supply part and the electric fan (air circulation part) The power supply unit and the electric fan cannot be directly connected, and a separate connection means is required. This increases the number of parts, increases the cost of the product, and makes it difficult to disassemble and assemble.

  Furthermore, the power supply connection terminal of the conventional electric fan is in the form of a pin protruding upward, and is inserted into a terminal socket opened below the connection means described above to be electrically connected. Such a structure not only requires the socket and pin to be aligned when the electric fan is installed, but also when the other side of the pin is lifted first when separating the electric fan, Means may be damaged.

  The present invention has been made to meet the above-described conventional requirements, and in at least one embodiment of the present invention, the length of the cooking plate is extended within a limited range of the entire length of the apparatus.

  The power supply unit 250 connected to the electric fan 520 has a detachable structure that can be disassembled and assembled to the electric roaster without a separate fixing means, and is connected when the power supply unit 250 or the electric fan 520 is mounted. The surfaces 1510 and 1511 are in parallel contact with the first and second supply contact surfaces 1500 and 1501.

  With the connection contact surfaces 1510 and 1511 in contact with the first and second supply contact surfaces 1500 and 1501, the power supply connection terminals 1540 and 1550 of the electric fan are elastically compressed.

  The power supply connection terminals 1540 and 1550 of the electric fan are accommodated in the accommodation groove so that a part thereof protrudes outside the accommodation groove of the connection terminal accommodation portion 1470, and one end thereof is extended to the motor 1340 side. An extension portion 1460 electrically connected to the terminal 1491 is included.

  As shown in FIG. 6, the end connected to the side surface on the lower surface of the electric fan power supply unit 280 is round-processed. Therefore, when the power supply unit 250 is pushed in horizontally and attached, the connection terminal accommodating unit The power connection terminals 1540 and 1550 of the electric fan projecting out of the housing groove 1470 and projecting higher than the lower surface of the electric fan power supply unit 280 before compression are not applied to the power supply terminals 1540 and 1550 of the electric fan. , 1550 can be moved along the lower surface of the electric fan power supply 280 while being compressed.

  In at least one embodiment of the present invention, the power connection terminals 1540 and 1550 of the electric fan are in the form of a coil spring in which one end projects out of the housing groove of the connection terminal housing portion 1470 and the other end is formed with an extension 1460. It is.

  In at least one embodiment of the present invention, the first electric fan power supply connection terminal 1540 is further separated from the second electric fan power supply connection terminal 1550 in the direction opposite to the motor 1340 side. This is because it is inserted in the diagonal direction when inserted into the power supply unit accommodating unit 150.

  In at least one embodiment of the present invention, the power supply connection terminals 1540 and 1550 of the electric fan have one end electrically connected to the terminal 1491 of the motor 1340 and the other end extended to the opposite side of the motor 1340. The leaf spring structure is formed so as to be elastically contactable with 250 first and second supply contact surfaces 1500 and 1501. For example, the first and second supply contact surfaces 1500 formed at a bent portion extending from one end connected to the terminal 1491 of the motor 1340 and an end portion of the bent portion and receiving elastic force by the bent portion, The structure includes the other end in contact with 1501.

  In at least one embodiment of the present invention, the first plane 1520 and the second plane 1530 on which the connection contact surfaces 1510 and 1511 are formed may be guided by the first and second connection contact surfaces 1510 and 1511, respectively. 910 and 920 may be formed.

  For example, as shown in FIG. 9, the guide portions 910 and 920 may be configured by grooves that connect from the outside (the lower surface end portion side of the electric fan power supply portion 280) to the first and second supply contact surfaces 1500 and 1501. it can. When the electric fan is mounted, the first and second connection contact surfaces 1510 and 1511 slide smoothly along the guide portions 910 and 920 to the first and second supply contact surfaces 1500 and 1501, thereby The physical impact on the power supply connection terminals 1540 and 1550 of the fan can be minimized.

  In at least one embodiment of the present invention, the connection contact surfaces 1510, 1511 are the ends of the springs, but in order to make electrical contact more reliable, a metal plate or metal ball is attached to the ends of the springs. An electrode member (not shown) having electrical conductivity such as may be attached.
