Description

Vertical electric baking oven lowering or hoisting gear

Technical field

The utility model relates to a kind of vertical electric baking oven, particularly a kind of vertical electric baking oven electric heater height lowering or hoisting gear that can arbitrarily adjust.

Background technology

Along with development and the growth in the living standard of society, much young man's eating habit and life style are in continuous change, not only barbecue device is brought to carry out outdoor barbecue when outdoor exercises or picnic, and at home also often assemble relatives and friends roast together, food roasting is more and more general, and food roasting and barbecue device are rapidly developed.The electric oven mode of heating of current use can be divided into underlying heating, side-mounted heating and overhead to heat three kinds.

The electric oven of underlying heating is from bottom to top to heat foods, because food is placed on baking tray, roasting face is positioned at bottom food, roasting face cannot be observed, very easily burned, because baking tray temperature is high, scald accident is easily there is during use, the oil smoke of the people that chokes can be produced when the oil droplet that food barbecuing is endured out drops on baking tray, not only affect health, and to environment.

The electric oven of side-mounted heating is from the side to heat foods, although can heating surface be observed, the oil smoke of the people that chokes can not be produced when the oil droplet that food barbecuing is endured out drops on baking tray, but the heating surface of direct irradiation is less, heat time is long, occur food marginal portion burned sometimes and the problem that mid portion is baked not yet, seldom use this kind of structure now.

The electric oven of overhead heating is from the top down to heat foods, roasting face is positioned at food top, conveniently can observe heating surface, food is not easily burned, bake the food colors come good, because baking tray temperature is low, the oil smoke of the people that chokes when the oil droplet that food barbecuing is endured out drops on baking tray, can not be produced, therefore, this structure is more and more subject to liking of consumers in general.As Chinese patent discloses a kind of upper heat source type electric oven, described stove seat to be connected with electric heater by support member and to be positioned at above stove seat.There is following problem in use procedure: because support member maintains static, height cannot regulate, no matter prey size, barbecue distance is consistent, and barbecue efficiency is low, and energy waste is serious.For this reason, many manufacturers and knowledgeable people have carried out fruitfully R and D, but not yet have rational product to emerge so far.

Summary of the invention

In order to overcome the above-mentioned disadvantage that existing vertical electric baking oven exists, the purpose of this utility model is to provide the vertical electric baking oven lowering or hoisting gear that a kind of rational in infrastructure, easy for operation, electric heater height arbitrarily can adjust in certain scope.

The utility model solves the problems of the technologies described above adopted technical scheme, it comprises electric heater, upper lifting arm, upper connecting rod, joint arm, lower lifting arm, lower link, baking tray base, the upper lifting arm top connection of described upper lifting arm and the electric heater joint of electric heater hinged, on upper lifting arm on symmetrically arranged upper lifting arm lower contact and lower lifting arm symmetrically arranged lower lifting arm top connection and joint arm by knob and the mutual cross-articulation of knob bolt, the lower lifting arm lower contact of lower lifting arm and the baking tray base joint of baking tray base hinged; Upper hinged seat on one end of described upper connecting rod and electric heater is hinged, lower hinged seat on one end of lower link and baking tray base is hinged, the hinged seat of the other end jointly and on joint arm of upper connecting rod and lower link is hinged, the upper parallelogram sturcutre of electric heater, upper lifting arm, upper connecting rod and joint arm composition, the lower parallelogram sturcutre of joint arm, lower lifting arm, lower link and baking tray base composition.

Further scheme of the present utility model, the corresponding brake disc being provided with activity in symmetrically arranged lower lifting arm top connection on described lower lifting arm, the brake shoe of brake disc matches with corresponding joint arm end face, the corresponding brake block being provided with activity in symmetrically arranged upper lifting arm lower contact on upper lifting arm, matching with corresponding brake disc end face in the inner of brake block, matches with corresponding knob and knob bolt end face in the outer end of brake block.

Further scheme of the present utility model, is provided with torsion spring between the electric heater joint of described electric heater and the upper lifting arm top connection of upper lifting arm, is provided with lower torsion spring between the baking tray base joint of baking tray base and the lower lifting arm lower contact of lower lifting arm.

Further scheme of the present utility model, described joint arm is provided with the upper limit position block preventing lifting arm from backward turning.

Further scheme of the present utility model, the baking tray base joint of described baking tray base is provided with the rear limited block matched with lower lifting arm, and the lower lifting arm lower contact of lower lifting arm is provided with the front limit block matched with baking tray base.

After adopting said structure, have the following advantages compared with the prior art and effect: one is that the height between electric heater and baking tray base is easy to adjust owing to adopting parallelogram double leval jib up-down adjustment structure.Two be due to upper lifting arm lower contact and lower lifting arm top connection and joint arm be interconnected between brake block and brake disc are set, upper lifting arm lower contact and lower lifting arm top connection and joint arm can be locked by turning knob, height when ensureing to use between electric heater and baking tray base can not change.Three is that arranging of upper and lower torsion spring can ensure that oscilaltion arm has certain reset force, and height adjusts easy and convenient.Four is turn over after upper limit position block can prevent lifting arm, and front and back limited block can ensure that lower lifting arm rotates in certain angular range.
