In addition, term " first ", " second " only are used to describe purpose, and can not be interpreted as indication or hint relative importance.
In description of the invention, need to prove that only if clear and definite regulation and qualification are arranged in addition, term " installation ", " linking to each other ", " connection " should be done broad understanding, for example, can be to be fixedly connected, connect integratedly, also can be to removably connect; Can be mechanical connection or electrical connection, also can be the connection of two element internals; Can be directly to link to each other, also can link to each other indirectly, for those of ordinary skill in the art, can understand the concrete implication of above-mentioned term as the case may be through intermediary.
Describe refrigerator in detail with reference to accompanying drawing below according to the embodiment of the invention.
Shown in Fig. 1-2, the refrigerator according to the embodiment of the invention comprises, casing 10, door body 20 and door opening/closing apparatus.
Be limited with a chamber (not shown) in the casing 10.
Said door opening/closing apparatus comprises the electromagnet 301 that is located on the casing 10, be located on the body 20 and with the suitable permanent magnet 302 of electromagnet 301 be located at said door handle on and the switch (not shown) that links to each other with electromagnet 301.So that electromagnet 301 when repelling each other with permanent magnet 302, a door body 20 is opened said chamber when the 301 first directions energising of said switch control electromagnet.So that electromagnet 301 when inhaling mutually with permanent magnet 302, a body 20 is closed said chamber when the 301 second directions energising of said switch control electromagnet.
That is to say, suppose permanent magnet 302 normal first magnetic that show, then when electromagnet 301 first directions are switched on, can make electromagnet 301 have first magnetic identical with first magnetic of permanent magnet 302.At this moment, mutually exclusive between electromagnet 301 and the permanent magnet 302 according to " same sex is repelled each other " principle, the user can open refrigerator doors like a cork, to realize opening the door action.And when electromagnet 301 second directions are switched on, can change the magnetic field of electromagnet 301 so that electromagnet 301 has second magnetic opposite with first magnetic of permanent magnet 302.At this moment, according to " there is a natural attraction between the sexes " principle, attract each other between electromagnet 301 and the permanent magnet 302, the user is closing refrigerator door like a cork, to realize closing the door action.
According to the refrigerator of the embodiment of the invention, the polarity through changing electromagnet 301 can make the user adopt less power to open the door and close the door with regard to accomplishing so that electromagnet 301 repels each other with permanent magnet 302 or inhale the function of opening the door or closing the door that realizes refrigerator mutually.
Need to prove that at this door body 20 can be pivotable being installed on the casing 10, also can be can extract out and can be installed on the casing 10 with pushing, does not do special qualification in the present invention.This is understandable for the person of ordinary skill of the art.
According to one embodiment of present invention, as shown in Figure 1, casing 10 comprises central sill 101, and electromagnet 301 is located on the central sill 101, and door body 20 comprises the end cap 201 corresponding with central sill 101, and permanent magnet 302 is located on the end cap 201.Thus, can rationally utilize the configuration design of current refrigerator, need not to change the existing design of refrigerator, reduce cost into installation electromagnet 301 and permanent magnet 302.
As shown in Figure 1, advantageously,, have installing hole 1011 on the central sill 101 according to an example of the present invention, electromagnet 301 is contained in the installing hole 1011.Thus, can beautify the outward appearance of refrigerator.
Further; According to concrete example of the present invention; As shown in Figure 1; Permanent magnet 302 is the strip permanent magnet, and electromagnet 301 has and the suitable accommodation hole 3011 of said strip permanent magnet, and first end of said strip permanent magnet (being the right-hand member of permanent magnet 302 as shown in fig. 1) links to each other with door end cap 201 and second end of said strip permanent magnet (being the left end of permanent magnet 302 as shown in fig. 1) is contained in the accommodation hole 3011 of electromagnet 301.Thus, can make electromagnet 301 tight with cooperating of permanent magnet 302.
Further, according to examples more of the present invention, permanent magnet 302 is a cylindrical magnet iron, and the cross section of the accommodation hole 3011 of electromagnet 301 is circular.Thus, can make electromagnet 301 further tight with cooperating of permanent magnet 302.
According to one embodiment of present invention, also comprise the checkout gear (not shown).Said checkout gear links to each other with electromagnet 301 with door body 20.When said checkout gear detects a body 20 and is in such as precalculated positions such as close the door position or opening positions, 301 outages of said checkout gear control electromagnet.
For instance, said checkout gear can be learnt a body 20 residing positions through the state that detects refrigerator intraoral illumination lamp.Particularly, when said checkout gear detected refrigerator intraoral illumination lamp and closes, then explanation door body 20 was in the closed position, can control electromagnet 301 outages this moment.When said checkout gear detected refrigerator intraoral illumination lamp and opens, then an explanation door body 20 was shown in an open position, and at this moment, also can control electromagnet 301 outages.Thus, can energy efficient and can prolong service life of electromagnet 301.
Simply describe below according to the refrigerator open of the embodiment of the invention and the process of closing the door.When the user need open refrigerator doors, the user can make the switch control electromagnet 301 first directions energising of door handle of refrigerator so that electromagnet 301 is identical with the polarity of permanent magnet 302, and electromagnet 301 repels each other with permanent magnet 302, thereby can easily open refrigerator doors.At this moment, refrigerator intraoral illumination lamp is opened, and after said checkout gear detects the signal of turning on light, can control electromagnet 301 outages.When the user needed closing refrigerator door, the user can make the switch control electromagnet 301 second directions energising of door handle of refrigerator so that electromagnet 301 is opposite with the polarity of permanent magnet 302, and electromagnet 301 is inhaled with permanent magnet 302 mutually, thus light closing refrigerator door.At this moment, refrigerator intraoral illumination lamp is closed, and after said checkout gear detects and closes modulating signal, also can control electromagnet 301 outages.
According to the refrigerator of the embodiment of the invention, the polarity through changing electromagnet 301 can make the user adopt less power to open the door and close the door with regard to accomplishing so that electromagnet 301 repels each other with permanent magnet 302 or inhale the function of opening the door or closing the door that realizes refrigerator mutually.
In the description of this specification, the description of reference term " embodiment ", " some embodiment ", " example ", " concrete example " or " some examples " etc. means the concrete characteristic, structure, material or the characteristics that combine this embodiment or example to describe and is contained at least one embodiment of the present invention or the example.In this manual, the schematic statement to above-mentioned term not necessarily refers to identical embodiment or example.And concrete characteristic, structure, material or the characteristics of description can combine with suitable manner in any one or more embodiment or example.
Although illustrated and described embodiments of the invention; Those having ordinary skill in the art will appreciate that: under the situation that does not break away from principle of the present invention and aim, can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present invention is limited claim and equivalent thereof.
