Description

Chassis structure of a heat source top-mounted oven

Technical field

The invention relates to the technical field of ovens, in particular to a chassis structure of a heat source top-mounted oven.

Background technique

Existing heat source under-floor ovens generally include a base, a baking tray disposed on the base, and a heat source disposed between the baking tray and the base. Use the heat from the lower heat source to bake the food placed on the baking tray. This structural scheme has the following drawbacks: in order to improve heat transfer efficiency, the heat source is installed as close as possible to the bottom surface of the baking tray, and the heat source is located in the base. When the heating is performed, the base also absorbs heat, and when the food is cooked, the heat source is turned off or the heat source is evacuated. The residual heat on the base will continue to dissipate and act on the food, causing excessive heating and affecting the taste. If charcoal is used as the heat source, the heating intensity of the conditioning adopts the method of adding or withdrawing charcoal. The griller needs to continuously add or withdraw charcoal according to the feeding speed. Avoid charred food, and the operation is cumbersome and difficult to control accurately. In addition, the heat source is located under the baking tray, and the heat generated by the heat source will pass through the baking tray and act on the bottom surface of the food. It is difficult for the operator to judge the raw food from the upper surface of the food. The degree is easy to cause excessive barbecue due to untimely observation, which affects the taste. In response to the above drawbacks, the inventors have devised an oven with a heat source, but there is no chassis (base and baking tray) that is compatible with strength and heat resistance, and if the chassis of the under-floor oven is used, There are defects such as structural mismatch, high cost, inconvenient movement of the baking tray, and inability to leave the heat source in time.

The outer wall of the metal support is provided with upper and lower annular protrusions, and the lower annular protrusion is in the elongated groove. Inside, the metal support member can slide along the long groove and can also rotate to meet the requirement that the baking tray can be moved and rotated during use. When the baking is good, the baking tray can be slid out of the baking area, or the user can be used. When sitting around with a barbecue, turn the baking tray to select food and so on.

One end of the elongated hole is provided with a detachable mounting plate. When assembling, the metal support member is first slid into the long groove from the position where the mounting plate is assembled, and then the mounting plate is assembled, and the assembly is tight, and the metal support The pieces are not easy to slide out.

The metal plate is provided with an elongated hole, the inner wall of the elongated hole is formed with an elongated groove, and the outer wall of the metal support is provided with upper and lower annular protrusions, and the lower annular protrusion In the elongated groove described. The metal support member has a cylindrical shape, and the inner wall is provided with a plurality of vertical protrusions having the same thickness. The positioning protrusion is a circular annular protrusion, and the positioning protrusion is positioned by the vertical protrusion, and is baked. The contact area between the disk and the metal support is small, heat transfer efficiency from the baking plate to the metal support is low, and heat loss is small.

Beneficial effect

The invention is obtained The chassis structure of a heat source top-mounted oven, the edge is a plastic material with poor heat transfer effect, the metal parts of the baking tray support are arranged, the high temperature resistance is good, and the user is prevented from being touched by the base and burned, and heat is avoided. Loss; set the oil passage of the baking tray, and export the waste oil to the baking tray to avoid the deposition of waste oil; the baking tray has a small supporting area and low heat loss rate; the baking tray slides and rotates reliably, and when the user barbecues, the moving baking tray exits. Or enter the toasting area or turn to the requirements for food selection or baking temperature.
