Abstract
The invention provides a structure for relieving negative pressure and freezing of a freezing chamber of a direct-cooling double-temperature refrigerator. The structure comprises a refrigerating chamber, the freezing chamber and a connecting pipe. The connecting pipe is arranged in a clapboard between the refrigerating chamber and the freezing chamber, and the refrigerating chamber is communicated with the freezing chamber through the connecting pipe which comprises an upper connecting pipe and a lower connecting pipe; the upper connecting pipe is installed on an inner container of the refrigerating chamber, the lower connecting pipe is installed on an inner container of the freezing chamber, and the upper end of the lower connecting pipe is sleeved with the lower end of the upper connecting pipe. According to the structure for relieving the negative pressure and freezing of the freezing chamber of the direct-cooling double-temperature refrigerator, frozen ice in the refrigerator can be reduced to a great extent, the cold and heat difference in the refrigerator is large when a heat source is closed, so that potential difference circulation is formed; a part of heat resource containing amounts of water vapor directly enters the refrigerating chamber and are slowly frozen into ice in the refrigerating chamber, and then the ice is smelted and flows out of a refrigerator body. Through experimental comparison, the freezing speed in the freezing chamber can be reduced by 29% under the same working condition.
Description
Technical field
The present invention relates to refrigerator technical field, be specially a kind of structure alleviating direct-cooled two-storage temperature refrigerator refrigerating chamber negative pressure and freeze.
Background technology
Direct-cooled two-storage temperature refrigerator, when normal refrigerating operaton, because refrigerating chamber cuts off with extraneous, forms a relatively airtight space.Air in this space is through refrigeration after-contraction, pressure reduces rapidly, the atmospheric pressure of external environment condition is greater than refrigerating chamber inner air pressure, door of refrigerator body is not easily opened, namely outside owing to there being outlet pipe to connect in refrigerating chamber, air pressure keeps balancing with outside, and the door body that can not occur because draught head causes is difficult to open.
Direct-cooled two-storage temperature refrigerator is when normal refrigerating operaton, and it is a kind of universal phenomenon that refrigerating chamber freezes, and this is also the greatest weakness of direct cooling refrigerator, and this technological invention also can reduce the icing phenomenon of refrigerating chamber.Under refrigerator is in normal operating condition, takes out or putting into article whenever opening the door when closing body again, a large amount of thermal source will be included in, wherein also containing a large amount of moisture content, these moisture content have finally all formed ice, and a part just knot, on evaporimeter and drawer, brings worries to user.
Summary of the invention
Technical problem solved by the invention is to provide a kind of structure alleviating direct-cooled two-storage temperature refrigerator refrigerating chamber negative pressure and freeze, to solve the problem in above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions: a kind of structure alleviating direct-cooled two-storage temperature refrigerator refrigerating chamber negative pressure and freeze, comprise: refrigerating chamber, refrigerating chamber, tube connector, described tube connector is arranged in the dividing plate between refrigerating chamber and refrigerating chamber, be communicated with by tube connector between refrigerating chamber with refrigerating chamber, described tube connector comprises tube connector, lower tube connector, described upper tube connector is arranged on refrigeration chamber courage, lower tube connector is arranged on freezing chamber courage, foaming layer is provided with between refrigeration chamber courage and freezing chamber courage, described upper tube connector lower end is set in outside lower tube connector upper end.
Described upper tube connector upper end is fastened on refrigeration chamber courage, and lower tube connector lower end is fastened on freezing chamber courage.
Described upper tube connector, lower tube connector are provided with ventilated membrane.
Compared with public technology, there is following advantage in the present invention: the present invention can reduce in case to a great extent freezes, after thermal source is closed, in case, cold and hot gap is larger, define potential difference circulation, the thermal source of part containing a large amount of steam just directly enters refrigerating chamber, at refrigerating chamber slowly Cheng Binghou thawing outflow casing.Through Experimental comparison, under equal working condition, the icing rate of in household freezer 29% can be reduced.

Fig. 1 is structural representation of the present invention.
Fig. 2 is connecting pipe structure schematic diagram of the present invention.
Detailed description of the invention
Object is reached and effect is easy to understand in order to make technological means of the present invention, creation characteristic, workflow, using method, below in conjunction with the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As Fig. 1, shown in Fig. 2, a kind of structure alleviating direct-cooled two-storage temperature refrigerator refrigerating chamber negative pressure and freeze, comprise: refrigerating chamber 1, refrigerating chamber 2, tube connector 3, described tube connector 3 is arranged in the dividing plate between refrigerating chamber 1 and refrigerating chamber 2, be communicated with by tube connector 3 between refrigerating chamber 1 with refrigerating chamber 2, described tube connector 3 comprises tube connector 31, lower tube connector 32, described upper tube connector 31 is arranged on refrigeration chamber courage 4, lower tube connector 32 is arranged on freezing chamber courage 5, foaming layer 7 is provided with between refrigeration chamber courage 4 and freezing chamber courage 5, described upper tube connector 31 lower end is set in outside lower tube connector 32 upper end.
Described upper tube connector 31 upper end is fastened on refrigeration chamber courage 4, and lower tube connector 32 lower end is fastened on freezing chamber courage 5.
Described upper tube connector 31, lower tube connector 32 are provided with ventilated membrane 6.
The present invention arranges the tube connector that has certain internal diameter between cold compartment of refrigerator and refrigerating chamber, connects refrigerating chamber and refrigerating chamber, makes refrigerating chamber, refrigerating chamber can keep identical air pressure with external environment condition, thus eliminates the negative pressure of refrigerating chamber.The internal diameter of tube connector is directly proportional to refrigerating chamber volume, and from 5mm to 25mm not etc., optimum position is that refrigerating chamber top is communicated with bottom refrigerating chamber to internal diameter.So just thoroughly solve the phenomenon of refrigerator negative-pressure, simple, do not increase how many costs.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Claimed scope of the present invention is defined by appending claims and equivalent thereof.
