The hidden handle can also be applied to various household appliances needing to be provided with handles, such as disinfection cabinets, dish washing machines, refrigerators, freezers and the like, the door body 4 is not limited to the three-layer glass door body 4, the common foaming door body 4 or door bodies 4 with other structures, the door body 4 can be installed and fixed by processing the same as the three-layer glass door body 4, and according to different household appliances needing to be installed, the forms of the structures are finely adjusted to determine whether the heat insulation materials at the supporting plate 12 and the back plate 13 are used or not, and whether or not the ventilation holes 51 need to be arranged on the vertical edges of the back cover plate 6, if the door body 4 is applied on the door body 4 of a refrigerator or a freezer, the ventilation holes do not need to be arranged on the vertical edges of the back cover plate 6, however, sufficient heat insulating material needs to be filled and fixed between the vertical edge of the back cover plate 6 and the back plate 13, so that the cold energy in the refrigerator or freezer is prevented from being conducted and dissipated through the structures such as the back cover plate 6, the back plate 13 and the like.
Hide the handle and at 4 surface parallel and levels of the door body under the normal state, make 4 outward appearances of the door body neater, the transportation of packing of also being convenient for, after receiving the opening signal (the signal can be electric power signal or outer effort), stretch out to the outside by actuating mechanism drive interlock mechanism 3 and then drive the handle body 7, supply the user to grip the handle body 7, pull out the door body 4. After receiving the signal again, the hidden handle is driven by the driving mechanism and the linkage mechanism 3 to contract back to the original position, and is flush with the door body 4 to form a hidden state. When the driving mechanism adopts the motor 21 as driving power, the motor 21 can be connected with a main control board of the steaming and baking oven, and a control signal is controlled and output by the main control board, or a handle control key is arranged on the main control board, a signal output end of the handle control key is connected with a signal output end of the main control board, a signal output end of the main control board is connected with a signal output end of the motor 21, or a signal output end of the handle control key is directly connected with a signal input end of the motor 21, after the power-on operation, the handle control key is pressed, the motor 21 operates, the pinion 22 drives the meshed gearwheel 23 to rotate, and then the rotating shaft 24 is driven to rotate, and the hidden handle is extended or retracted by the linkage mechanism 3 under the driving of; or a handle control key is not needed to be arranged, the signal output end of the main control board is connected with the signal input end of the motor 21, after the steaming and baking oven is powered on to operate, the main control board directly controls the motor 21 to operate, so that the handle body 7 extends out as described above, the temperature of the handle body 7 is prevented from rising due to heat dissipated by the door body 4, bad experience is brought to a user, after the power is off, the motor 21 automatically rotates to withdraw the handle body 7, or the signal output end of the main control board is connected with the signal input end of the motor 21, after the power is on, the main control board directly controls the motor 21 to operate to drive the handle body 7 to extend out, when the program is completed, after the door body 4 of the steaming and baking oven is opened and closed again, the program is finished and the power is turned off, and. In practical application, the required control method or combination of several control methods can be selected by combining the various control methods described above.
To sum up, the utility model provides a pair of heating panel of hidden handle compares with prior art, has following advantage:
1. the heat dissipation plate has a simple structure, and can effectively dissipate heat of the driving mechanism while effectively protecting the driving circuit;
2. the screw seat can synchronously play a role in supporting and fixing, so that the strength of the heat dissipation plate is enhanced;
3. the fixing folded edge formed by continuously bending the top of the heat dissipation plate further strengthens the strength of the heat dissipation plate and provides an installation position for the driving device.
Similar solutions can be derived as described above in connection with the given solution content. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical substance of the present invention are still within the scope of the technical solution of the present invention.
