Description
Technical field
What the present invention relates to is micro-wave oven, particularly be the invention of the door bolt plate structure aspect of micro-wave oven.
Background technology
Micro-wave oven is the household electrical appliance that utilize electromagnetic wave cooking food, and in order not make leakage electromagnetic wave outside, door must be close on the body of micro-wave oven fully, and therefore, micro-wave oven must be provided with the door bolt system.In the door bolt system, the door bolt plate effect extremely important.
Describe below in conjunction with the door bolt plate structure of accompanying drawing the prior art micro-wave oven.
Existing microwave oven structure is useful in electric control chamber and generates electromagnetic waves and to its electric-controlled parts of controlling, and above-mentioned electric control chamber is on the right side of furnace cavity, and the front that the controller that is used for peripheral operation is positioned at electric control chamber is the right side of door just.
The door bolt system of prior art is fixed on the door bolt plate on the flange of front panel with a plurality of screws, and the front panel flange is used for the installation of controller.
As depicted in figs. 1 and 2, there is door 3 front of the furnace cavity 1 of micro-wave oven, and door 3 is connected with body and can opens and closes with hinge 8, by being arranged on the door bolt (not pointing out out in the drawing) on the door, makes and body is close to fully, prevents electromagnetic-wave leakage.The right side of furnace cavity 1 is an electric control chamber 5, and the electric-controlled parts of magnetron 51, transformer 52 and electric capacity 53 etc. is housed in the electric control chamber 5, and the front of the electric control chamber 5 just right side of front panel 7 is equipped with controller 4.
A plurality of air ostiums 11 are arranged on the front upper side face on furnace cavity 1 right side, the moving air that produces by cooling fan 54 cools off above-mentioned electric-controlled parts, and by the stove lamp 55 of air duct 56 cooling settings in air duct 56, flow into then in the cooking room 2, the steam in the cooking room is discharged from air outlet slit (not pointing out out the drawing).The stove lamp is used to confirm the cooking food state in the cooking room, is installed in the air duct 56 and air ostium 11 places, and leaked-in air is cool furnace lamp effectively just.
On the plate 7 installing space 74 is arranged in front, installing space 74 is used to install controller 4, in the left side of installing space 74 front panel flange 72 is arranged, the front panel flange 72 that is used to install controller rearward is bent to form, on the front panel between installing space 74 and the cooking room 2 door bolt hole 71 is arranged, can insert the door bolt (not pointing out out in the drawing) that is arranged on the door 3 in the door bolt hole 71.
Carry out open/close a plurality of safety switch 104 by door bolt and be installed on the door bolt plate 100, door bolt plate 100 back side in the door bolt hole 71 of plate 7 in front is fixed on the front panel flange 72 with a plurality of screws 103.For door bolt plate 100 is fixed on the front panel flange 72, a plurality of fixedly connected holes 73 are arranged on the plate flange 72 in front, screw mounting hole 102 is arranged on the door bolt plate 100.
In addition, the door bolt gateway 101 in corresponding above-mentioned door bolt hole 71 is arranged on door bolt plate 100, when door bolt inserts or withdraws from door bolt gateway 101, then can open and close safety switch.
But the micro-wave oven with prior art of said structure but has following defective:
The door bolt system of prior art is installed in the door bolt plate on the front panel flange, because front panel is thinner than above-mentioned furnace cavity, promptly use two screws to fix, the door bolt plate also can produce vibration under the elastic force effect of door bolt spring (not pointing out out in the drawing) when shutter door.Therefore may lead to errors handling safety switch or the danger of leakage electromagnetic wave occurs needs independent air duct for this reason, but also will use a plurality of screw fixed gate pinboards, is unfavorable for assembling and cost is improved.
The micro-wave oven of above-mentioned prior art is upside or the downside that controller is placed on door, causes the capacity of cooking room little.In order to increase the capacity of cooking room, if controller of microwave oven is arranged on the top or the bottom of a body self, make controller and door form an one, door bolt plate fixing, can separately carriage be installed on the front panel, but adopt this spline structure that cost is risen.
Summary of the invention
The objective of the invention is in order to solve the defective of above-mentioned prior art, providing a kind of is that the door bolt plate is firmly fixed when being combined on the body, reduce number of components, increase the capacity of cooking room, prevent the maloperation and the leakage electromagnetic wave of safety switch, reduce the door bolt plate structure of the micro-wave oven of manufacturing cost.
The present invention solves the problems of the technologies described above the technical scheme that is adopted:
A kind of door bolt plate structure of micro-wave oven, its structure comprises a plurality of safety switches by door bolt, is positioned at the door bolt gateway of door bolt plate upper and lower, the door bolt plate that is positioned at the furnace cavity right side also comprises fixing combination and following fixing combination, the outstanding to the left top that is formed on the door bolt plate of last fixing combination, the outstanding to the left bottom that is formed on the door bolt plate of following fixing combination; The last fixing combination secure bond of door bolt plate is on the upper plate on furnace cavity right side, and the following fixing combination secure bond of door bolt plate is on the lower side panel on furnace cavity right side.
The present invention also provides a kind of door bolt plate structure of micro-wave oven, its structure comprises a plurality of safety switches by door bolt, is positioned at the door bolt gateway of door bolt plate upper and lower, and the door bolt plate that is positioned at the furnace cavity right side also includes fixing combination, fixing combination and stove lamp fixing combination portion down; The outstanding to the left top that is formed on the door bolt plate of last fixing combination, the outstanding to the left bottom that is formed on the door bolt plate of following fixing combination; The last fixing combination secure bond of door bolt plate is on the upper plate on furnace cavity right side, and the following fixing combination secure bond of door bolt plate is on the lower side panel on furnace cavity right side; The side-prominent backward upside that is formed on the door bolt plate of stove lamp fixing combination portion of secure bond stove lamp is useful on the hook (231) of secure bond stove lamp on stove lamp fixing combination portion.
The invention has the beneficial effects as follows: the present invention since with door bolt plate secure bond on furnace cavity, make fixing very firmly can not the trembleing of door bolt plate to have prevented the faulty operation and the electromagnetic leakage of safety switch effectively.The present invention can only carry out secure bond with a screw and form all-in-one oven lamp fixing combination portion, can bring into play the air guide effect, and the guiding air flow in the cooking room.By reducing number of components, improve assembleability and reduce cost.
