Description

Range hood vertical transfer device {Vertical transfer device for range hood}

The upper and lower conveyers of the range hood of the present invention are located in the electric cylinder in which the main parts and the power transmission device constituting the conveying apparatus are all formed to form a unit, so that the overall volume is minimized and the installation space is limited. It is easy to install because it is not received, and it is possible to install without limit of range hood type, and it is possible to effectively and powerfully discharge smoke, food smell and heat generated during cooking at a closer distance, and to suppress noise. It relates to a vertical conveying device of the hood.

The conventional range hood is fixedly installed on the wall or upper storage cabinet of the cooking range of a general house or apartment kitchen, and includes a suction fan and a power motor provided with smoke, food odor and harmful gas generated when cooking food. Inhaled and discharged. However, since the conventional range hood is fixedly installed on the wall or upper cabinet above the cooking range as described above, the distance from the cooking range is too far, and the cooking range is opened between the range hood and the range. It is not possible to effectively discharge the smell and heat generated, and even if the suction power of the range hood is increased, the powerful suction power cannot be exerted in a large area, so that the role of the range hood cannot be sufficiently performed and the noise is large. There is this.

In addition, in order to improve the above problems, as shown in Figure 1, a range hood having a device for moving the range hood up and down has been devised, the transfer device mounted on the range hood comprises the transfer device. The parts (driving motor, pinion, wire, etc.) which are not composed of a single unit are installed separately, so that the overall conveying device becomes bulky, and it is difficult to install in a limited space. There is a problem in that the coupling structure is complicated and maintenance and repair are not easy when a failure occurs. In particular, when the wall-mounted hood is installed, the width between the upper cabinets of the kitchen where the hood is installed is standardized to 600mm, 900mm, etc., and the depth of the cabinets is standardized to 310mm and 350mm, so that the transfer is not unitized in a limited space. The device is difficult to install individually and to be combined with the hood. In addition, as described above, the conveying device in which the components are individually installed may not be installed in the island-type hood fixed to the ceiling of the kitchen rather than being fixed to the cabinet, because there is no suitable place to install the components constituting the conveying device. There is a problem. In addition, the transfer device is an open type so that the noise generated from the driving device is transmitted to the user as it is, and exposed to heat, oil and steam generated during cooking, which has a fatal effect on the durability of the transfer device.

The upper and lower conveyance devices of the range hood of the present invention devised to solve the above problems are all located in the electric cylinder in which the main parts and the power transmission device constituting the conveying device are sealed to form a unit, so that the volume is minimized as a whole. It is easy to install because it is not restricted by the installation space, and it can be installed without any kind of range hood, and it can discharge the smoke, food smell and heat generated during cooking efficiently and powerfully at a closer distance. It is an object of the present invention to provide a range hood up and down feed apparatus capable of suppressing the loss.
