Abstract
The utility model discloses a microwave oven with a convenient attraction-closed mode door body. The utility model comprises an oven body and an oven door which is hinged on the oven body. Touch pressure switches for control the on and off of a power source loop, permanent magnets, and ferromagnetic material attraction-closed devices are mutually and correspondingly provided between the oven door and the oven body. One or more than one electromagnet devices are arranged on the frame positions of the opening part of the oven body, and ferromagnetic materials are arranged on the positions of the inner side of the oven door, and the positions are corresponding to electromagnets. An electromagnet coil is connected with a power source circuit by a control timer in the microwave oven with the convenient attraction-closed mode door body. The utility model can solve the problem that the utility model is tight jointed to prevent electricity from leaking in the state of work in the design that the oven door is closed by using an attraction-closed mode; meanwhile, the oven door is ensured that the oven door is convenient to be opened after the oven door works.
Description
Technical field
The utility model relates to the improvement technology to microwave oven.
Background technology
On traditional door for microwave oven body, be provided with a touch-pressure switch that is used to control the electric power loop break-make usually with mechanical striker mechanism and be connected hinge.In order to save the complicated mechanical locking mechanism, there is the people once to propose fire door to be pull-in on the body of heater and substitutes mechanical striker mechanism with permanent magnet, reach the purpose of avoiding the leaky wave phenomenon that the wearing and tearing because of mechanical striker mechanism and hinge cause.Because it is strong excessively that permanent magnet exists magnetic force, easily cause the problem of opening fire door inconvenience, a little less than crossing, magnetic force do not reach the effect of anti-leaky wave again.In order to make the magnetic mode of closing have more practicality, just must on original magnet structure basis, improve the structure that magnetic closes.
Summary of the invention
A kind of suction type door body micro-wave oven that makes things convenient for described in the utility model is utilizing the magnetic mode of closing to cut out in the design of fire door, can solve under the duty to fit tightly, and the problem of anti-leak guarantees again that simultaneously fire door can conveniently open after work.
The suction type door body micro-wave oven that makes things convenient for described in the utility model comprises body of heater and the fire door that is articulated on the body of heater, and correspondence is provided with touch-pressure switch, permanent magnet and the ferrimagnet adhesive device of controlling the electric power loop break-make mutually between fire door and body of heater; Oral area frame place at body of heater is provided with one or more electromagnet apparatus, at the inboard corresponding above-mentioned electromagnet of fire door place, is provided with ferrimagnet, and described electromagnet coil connects power circuit by the control timer in the micro-wave oven.
The aforesaid suction type door body micro-wave oven that makes things convenient for, described electromagnet and ferrimagnet are arranged at the vertical frame place away from installation hinge one side of body of heater and fire door.
The aforesaid suction type door body micro-wave oven that makes things convenient for, described electromagnet and ferrimagnet are arranged at the upper and lower side frame of body of heater and fire door away from hinge one side place is installed.
The aforesaid suction type door body micro-wave oven that makes things convenient for, described two above electromagnet and ferrimagnet are by being symmetrical arranged up and down.
The utility model is compared with traditional permanent magnet adhesive structure, has following advantage and positive effect:
1. when micro-wave oven was worked, magnetic attraction was the strongest, and it is more tight that body of heater and fire door card are closed, and anti-leak result is better;
2. when micro-wave oven is not worked, magnetic attraction a little less than, only have the suction of permanent magnet to exist, instant microwave is door opened;
3. magnetic closes simple in structure, practicality and simple installation.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is another structural representation of the present utility model;
Fig. 3 is an electromagnet power supply catenation principle block diagram described in the utility model.
The specific embodiment
Concrete structure of the present utility model can provide an embodiment with three electromagnet referring to accompanying drawing: Fig. 1, wherein the touch- pressure switch 4,5 of body of heater 1, fire door 6, hinge 7, permanent magnet 4,11 and control electric power loop break-make is traditional structure setting, the utility model improvements are to inlay to be provided with several electromagnet on body of heater oral area frame 2, in fire door 6 inboard corresponding positions, be provided with ferrimagnet with electromagnetic actuation.4,11 and three electromagnet 8,9,10 of permanent magnet can be that the fire door frame is iron material corresponding to the ferrimagnet on the fire door among the figure, also can be that the ferromagnetism that embeds on the position, corresponding position is inhaled piece (not shown this part).
Fig. 2 provides another embodiment, in the drawings as can be seen, electromagnet is four, and wherein electromagnet 12,13 is arranged at cabinet 1 lower frame away from hinge one side, electromagnet 14,15 is arranged at cabinet 1 upper side frame away from hinge one side, and they are by being symmetrical arranged up and down.Be provided with ferrimagnet equally in the inboard corresponding position of fire door.
Other set-up mode can also be selected in the number of electromagnet and position, respectively establishes one or only be provided with one or two on the vertical frame of body of heater as the body of heater upper and lower side frame.
The electrical working time of described electromagnet and the working time of micro-wave oven are synchronous.A control circuit is set in the described electromagnet current supply circuit, and the work timing of this control circuit and micro-wave oven is synchronous.For example: can utilize the timer circuit in the micro-wave oven, directly control the working power of this electromagnet.Above-mentioned synchronous control mode also can adopt the timer of micro-wave oven, and to the indirect control mode of electromagnet, promptly timer carries out break-make control to an electronic switching element, and described electronic switching element string is in the electromagnet current supply circuit.
