Description
Technical field
The present invention relates to a kind of micro-wave oven, particularly relate to a kind of can about the door bolt plate of the micro-wave oven that connects of two directions.
Background technology
Micro-wave oven is a kind of device of cooking food.Micro-wave oven can produce microwave by magnetron when connecting power supply, and this microwave irradiation just can be heated to heating object.Such micro-wave oven is divided into two kinds substantially, promptly generally is placed on the common microwave stove that uses on the kitchen tools and is arranged on the Gas oven and has the enclosure dual-purpose micro-wave oven of degassing function.And can be divided into side open and close type structure of generally using and the pull-down structure of opening from top to bottom according to the structure of door for microwave oven.Fig. 1 is the pull-down microwave oven exploded perspective view of prior art.As shown in Figure 1, the micro-wave oven of this prior art by the cavity assembly 10 of portion's cooking food within it, be centered around the outside of cavity assembly 10 and form the shell 20 of external structure and as required the selectivity fire door 30 that opens and closes cavity assembly 10 form.Wherein, cavity assembly 10 is by being used for placing the cavity 11 for the treatment of cooking food, the right side that is arranged on cavity 11 and forming for the main 13a of electricity storage chamber, the auxiliary 13b of electricity storage chamber that is arranged on cavity 11 tops, the front panel 15 that is arranged on cavity 11 front ends that cooking food are provided with multiple electric component, the rear board 19 that is arranged on the bottom panel 17 of bottom and is arranged on the back side.Cavity 11 is to place the space treat cooking food, and its bottom is rotating, thereby heat food equably.The bottom is rotated food is rotated, but also can make bulky food move left and right.The side of cavity 11 is provided with the steam vent that steam inside is discharged in a plurality of not shown being used for.And, being arranged on the front panel 15 of cavity 11 fronts, the rear board 19 that is arranged on the bottom panel 17 of bottom and is arranged on the back side is to be made by steel plate, it can protect cavity 11 and the 13a of electricity storage chamber effectively, and 13b is in case it is subjected to the influence of external impact.Front panel 15 is provided with pin hole 15a and pan 15b, and these structures can be installed and selectivity opens and closes fire door 30.The upper end of front panel 15 is connected with fore-stock 16, and is combined with the control panel 31 that the state that can demonstrate cavity 11 also can be controlled running of microwave oven on the fore-stock 16, and control panel 31 is provided with the button 40a that is used for importing user's operation species.Fire door 30 is combined in the front of micro-wave oven, and it can make the front end face of cavity 11 open and close selectively.Because it is harmful to be radiated at the microwave of cavity 11 inside, so fire door 30 must close whole cavity 11 during the running of microwave oven.Fire door 30 is close on the front panel 15, and it utilizes hinge to be hinged on the bottom of front panel 15, and the upper rear portion of fire door 30 is provided with and not shown can be inserted into the latch in the pin hole 15a on the front panel 15, thereby makes fire door 30 seal up front panel 15.The back side left and right sides of front panel 15 is respectively equipped with the left and right sides door bolt plate 40,50 that can fix latch on the fire door 30.Door bolt plate 40,50th adopts board bracket to be connected to the back side of front panel 15.Fig. 2 a is an offside door pinboard structural perspective among Fig. 1.Fig. 2 b is an offside door pinboard structural perspective among Fig. 1.Shown in Fig. 2 a, Fig. 2 b, because left and right sides door bolt plate 40,50th is symmetrical, so be that benchmark describes with offside door pinboard 50 here.Shown in Fig. 2 b, offside door pinboard 50 vertically extends by the framework 51 with a certain size with from the edge of framework 51 and the support end 53 that forms constitutes.Outstanding a plurality of hinge 51a and the hook 51b of being formed with in the inside of framework 51.Hinge 51a is provided with the bar 55 that can rotate.Support the middle part of end 53 to be provided with the opening portion 53a that front and back are communicated with.Opening portion 53a is that the latch on the fire door 30 inserts the path of door bolt plate 50 inside.Be provided with switch 57 between the framework 51 inner hook 51b that form, switch 57 can be realized according to the rotation of bar 55 opening and closing.When to door bolt plate 50 is inner when inserting latches, bar 55 will be that rotate at the center with hinge 51a, and the switch 57 that promotes to be installed in the one side thus carries out on-off action, the insertion of latch be fire door 30 close simultaneous.In addition, be formed with two on the upper and lower side of offside door pinboard 50 respectively from the outstanding right side connection projection 59 of the right flank of framework 51 to the right, and the inside of right side connection projection 59 is provided with right side connecting hole 59a.The back side of plate 15 is provided with door bolt plate 40 in front, 50 process is as follows: the back side of plate 15 vertically is provided with not shown board bracket at first in front, the top and the bottom of board bracket are left and can be carried out bolted combined hole, under the situation that offside door pinboard 50 is covered by board bracket, the right side connecting hole 59a of offside door pinboard 50 and the combined hole of board bracket are alignd, install screw then, thereby offside door pinboard 50 is fixed on the right side, the back side of front panel 15.Equally, under the situation that offside door pinboard 40 is covered by board bracket, the left side connecting hole 49a of offside door pinboard 40 and the combined hole of board bracket are alignd, install screw then, thereby offside door pinboard 40 is fixed on the left side, the back side of front panel 15.But, left and right sides door bolt plate 40 with said structure, 50 exist following problem: as Fig. 2 a, shown in Fig. 2 b, left side connecting hole 49a on the offside door pinboard 40 and the right side connecting hole 59a on the offside door pinboard 50 are respectively formed at framework 41,51 upper end, it is the upper left-hand that the left side connecting hole 49a of offside door pinboard 40 is positioned at framework 41, the right side connecting hole 59a of offside door pinboard 50 then is positioned at the upper right of framework 51, so in order to form a symmetrical left side, right side connecting hole 49a, 59a, must make offside door pinboard 40 and offside door pinboard 50 respectively with two different moulds, the expense of making mould is risen, and the result can cause the micro-wave oven cost to increase.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of door bolt plate that can make the door bolt plate as required at the micro-wave oven of the selective installation of left and right sides both direction.
In order to achieve the above object, it is can be with hinge fixing and can make the framework of the bar that switch moves that the door bolt plate of micro-wave oven provided by the invention comprises that the side is provided with, and the fire door that is arranged on the micro-wave oven front is opened and closed selectively, be respectively equipped with a plurality of connection projections on the left and right side of described door bolt plate, thereby it can be connected at left and right sides both direction.
The right flank of described door bolt plate is formed with the right side to the right and connects projection, and left surface is formed with left side connection projection to the left.
Described right side connection projection is connected projection with the left side inside is respectively equipped with right side connecting hole and the left side connecting hole with screw thread.
The door bolt plate of micro-wave oven provided by the invention is to form connecting hole on the left and right side of door bolt plate simultaneously, so just can select the closure of screw as required arbitrarily, one type door bolt plate can not only be installed in the left and right sides of fire door, thereby reduce the kind quantity of parts, but also can simplify assembling process, thereby increase work efficiency.In addition, owing to can use a mould to make the door bolt plate, so can reduce the manufacturing expense of mould.
