Problems solved by technology

That is, the frequency of opening and closing of the refrigerator door is generally about 40-50 times per day, and the opening and closing intervals are relatively long. However, due to naughty children and display in stores, etc., sometimes the door will be continuously opened and closed intensively.
At this time, the temperature rise caused by one energization of the electromagnetic solenoid is very small, and there will be no problem if there is a certain period of heat dissipation, but if the switching operation is performed continuously as described above, it may cause a significant temperature rise. to abnormally high temperature

Embodiment 4

[0110] Figure 14 The appearance of the upper part of the refrigerator 201 which is a storage is shown. On the top of the refrigerator body 202 of this refrigerator 201, a refrigerator compartment 203 as a storage compartment is formed, and on its front side, a hinge 205 at one end is rotatably provided to open and close the front opening of the refrigerator compartment 203. Rotary door 204. A sealing gasket 206 is provided on the peripheral portion of the inner surface of the door 204 . Such as Figure 17As shown, the sealing gasket 206 is provided with a magnet 207, and the sealing gasket 206 is adsorbed on the front side of the refrigerator body 202 when the door 204 is closed.

[0111] Between the above-mentioned door 204 and the refrigerator body 202, at the position of the lower hinge part, there are such Figure 16 Self-closing mechanism 208 as shown. This self-closing mechanism 208 is a well-known structure that is formed by the locking part 209 that is located at...

Abstract

A door opening device for a food storage apparatus such as a household refrigerator includes a generally cylindrical coil unit (12) mounted on a body (1) of the storage apparatus and having an axially extending through hole (105), a plunger (14) mounted in the hole (105) of the coil unit (12) so as to be axially moved with respect to the coil unit (12), the plunger (14) being moved in a direction when the coil unit (12) is energized, and a pushing member (15) mounted on one axial end of the plunger (14) so as to be moved with the plunger (14), the pushing member (15) pushing the door (2a) in an opening direction against a sticking force of the magnet gasket (2b) when moved in the one direction with the plunger (14).

Description

[0001] This application is a divisional application of the invention application entitled "The Door Opening Device of Storage Warehouse" with the application number 00124181.8 submitted on August 17, 2000. technical field [0002] The present invention relates to a door opener for a storage room having a door kept closed by a magnetic seal. [0003] Moreover, this invention relates to the door-opening apparatus for storage rooms provided with the unit for opening a solenoid type door. Background technique [0004] In recent years, the size of the refrigerator used as a storehouse has obviously tended to increase, and the door for opening and closing the refrigerator etc. has also tended to increase in size accordingly. The general structure of the door for such a refrigerator is to keep its closed state by the adsorption force of the magnetic seal. However, if the door is enlarged, the total extension length of the magnetic seal becomes longer. The necessary operating force...
