Definitions

  • the present utility model relates to a refrigerating device, and particularly to a refrigerating device having an evacuatable chamber.
  • the existing refrigerating device adopts an evacuatable chamber to reduce oxygen content in the chamber so as to increase storage effects of items, thereby prolonging storage time.
  • the evacuatable chamber (which may also be called “low-pressure chamber”) uses a vacuum pump for evacuation.
  • An object of the present utility model is to provide a refrigerating device having an evacuatable chamber that can further reduce energy consumption.
  • the present utility model provides a refrigerating device, including at least two storage chambers, a housing defining an evacuatable chamber and a vacuum pump used to evacuate the chamber, wherein the housing is disposed in one storage chamber, and exhaust of the vacuum pump is introduced into at least one of the two storage chambers.
  • the technical solution has the following advantages: as the housing is disposed in one storage chamber, gas pumped out by the vacuum pump from the chamber defined by the housing is low-temperature gas, discharged gas is also low-temperature gas, and relative to that the low-temperature gas is discharged outside the refrigerating device and the storage chamber cools normal-temperature gas entering from the outside, the low-temperature gas discharged by the vacuum pump is directly introduced into any storage chamber or multiple storage chambers, which can reduce energy consumption.
  • the "evacuatable chamber” in the present utility model refers to that the chamber is evacuatable and has pressure which is lower than atmospheric pressure, for example, the chamber can be decompressed to make the pressure in the chamber kept between the atmospheric pressure and absolute vacuum.
  • the evacuatable chamber may also be called “low-pressure chamber” or “vacuum chamber”.
  • an exhaust pipe of the vacuum pump is connected to at least one of the two storage chambers.
  • the exhaust pipe of the vacuum pump is connected to all the storage chambers or one or more in all the storage chambers, all of which can reduce energy consumption.
  • the storage chambers into which the exhaust of the vacuum pump is introduced are fresh-keeping chambers, refrigerating chambers or freezing chambers.
  • the scheme provides three specific schemes for introducing the low-temperature gas discharged by the vacuum pump into the chamber, in particular, it should be noted that, for the freezing chamber, its temperature is lower, which is generally subzero, when a user opens the door that closes the freezing chamber, outside air enters into the freezing chamber, the temperature of the entering normal-temperature gas is lowered in the freezing chamber, while the volume is unchanged, thus the pressure is reduced, this results in that the user needs great efforts to open the door next time he/she opens the door of the freezing chamber, and discharging the low-temperature gas discharged by the vacuum pump into the freezing chamber can increase the pressure in the freezing chamber, thus facilitating the user to open the door in the case of saving efforts.
  • the vacuum pump and the housing are placed in the same storage chamber, and the storage chamber accommodating the vacuum pump and the housing is a fresh-keeping chamber or refrigerating chamber.
  • the vacuum pump may be placed in a compressor room, or like the scheme, be placed in the same storage chamber with the housing, thereby shortening the length of the evacuatable pipeline and reducing the cost.
  • the scheme also provides two specific schemes for the chamber that accommodates the vacuum pump and the housing.
  • the vacuum pump is disposed in an accommodation shell, and the accommodation shell and the housing are placed in the same storage chamber.
  • the vacuum pump may vibrate during evacuation, thus, when the vacuum pump is directly fixed to an outer wall of the housing or an inner wall of the storage chamber, the vacuum pump will drive the housing or a storage chamber inner tank to vibrate together, noise is greater, and after the vacuum pump is housed in the accommodation shell, noise produced by them can be reduced through a buffer structure or the like when the accommodation shell is fixed with the housing or the storage chamber inner tank.
  • a wall of the accommodation shell has an opening, used for passing of the exhaust of the vacuum pump.
  • an opening is opened on a wall of the accommodation shell, which can avoid connections of exhaust pipelines and reduce the cost.
  • an exhaust pipe is connected between the accommodation shell and the other storage chamber except for one storage chamber where the housing and the accommodation shell are placed.
  • the vacuum pump is placed in one storage chamber, exhaust is introduced into such a storage chamber, it is also feasible to introduce the exhaust of the vacuum pump into another storage chamber, for example, through a Y-pipe or a one-in-two-out valve, and in this case, an exhaust pipe is connected between the accommodation shell and the other storage chamber.
  • the exhaust of the vacuum pump may also be completely introduced into the other storage chamber.
  • the exhaust pipe is a soft tube, and at least part of the soft tube is accommodated in a hard tube.
  • the exhaust pipe is preferably a soft material, for example, plastic
  • the soft exhaust pipe, in the foaming process of the refrigerating device may be wrapped by a foaming liquid, and to prevent the foaming liquid from squeezing the soft tube, preferably, a hard tube is disposed outside some sections of the soft tube.
  • the vacuum pump is disposed in an accommodation shell, outer walls of the housing enclose a recessed area recessed towards the chamber, and the recessed area is used to accommodate the vacuum pump.
  • the scheme further disposes a recessed area on outer walls of the housing to accommodate the accommodation shell (or vacuum pump), and advantages of the scheme are as follows: the vacuum pump, the accommodation shell and the housing (or the vacuum pump and the housing) form a vacuum storage unit standard part, the standard part has good compatibility, which is suitable for a certain type of refrigerating devices, for example, refrigerators, can be added to refrigerating devices having different platforms/models according to requirements, and does not need to adjust layout in the existing refrigerating device, which thus increases applicability of the vacuum storage unit in the refrigerating devices having different platforms/models and is conducive to simplifying assembling of refrigerating devices having vacuum storage units, thereby helping to increase assembling efficiency.
  • the accommodation shell (or vacuum pump) is completely housed in the recessed area.
  • Advantages of the scheme are as follows: the housing and the accommodation shell (or vacuum pump) are placed at the same time by using the existing space accommodating the housing, that is, the existing storage chamber that can accommodate the housing, i.e., can accommodate the standard part formed by the housing and the accommodation shell (or vacuum pump), and the internal structure of the existing refrigerating device is changed slightly.
  • the outer walls of the housing enclosing the recessed area are shared with some walls of the accommodation shell.
  • the scheme can avoid setting of various walls of the accommodation shell, thus helping to reduce the cost.
  • walls of the accommodation shell and the outer walls of the housing enclosing the recessed area have gaps therebetween.
  • Advantages of the scheme are as follows: the shape of the outer walls of the housing can make targeted setting according to transformation in the evacuation process of the housing, and some buffer structures can be disposed between the accommodation shell and the outer walls of the housing to reduce noise of the vacuum pump in the evacuation process.
  • the refrigerating device is a refrigerator, a freezer or a wine cabinet.
  • the present utility model puts forward: introducing exhaust of a vacuum pump into a storage chamber where a housing defining an evacuatable chamber is placed or other chambers outside such a storage chamber, and relative to that low-temperature gas discharged by the vacuum pump is discharged outside the refrigerating device and the storage chamber cools normal-temperature gas entering into the refrigerating device from the outside, the low-temperature gas discharged by the vacuum pump is directly introduced into any storage chamber or multiple storage chambers, which can reduce the energy consumption.
