Abstract
Description
- The present disclosure relates to a refrigerator vegetable room and a refrigerator with the same for storing fresh foods such as fruits or vegetables in a distinguished manner from the other foods and drinks.
- In general, refrigerator is an apparatus for generating cool air by the driving of a freezing cycle provided therein, and storing foods and the like for a long period of time in a low temperature state by supplying the cool air to an inner portion of a refrigerating chamber and a freezing chamber.
- It has been known that factors affecting the quality of fresh vegetables include temperature, humidity, environmental gases, microbes, light, and the like. Vegetables continuously perform respiration and transpiration, and thus the suppression of such respiration and transpiration is required to maintain the quality of fresh vegetables. Most vegetables, except some vegetables such as those susceptible to lower temperature damage, respiration can be suppressed at low temperature, and transpiration can be prevented at high humidity.
- For this reason, the refrigerator is provided with a vegetable room for storing vegetables as an independent space from the refrigerating chamber to store vegetables in a fresh state for a long period of time. The vegetable room maintains a suitable low temperature state as well as maintain an attainable high humidity state. In other words, the vegetable room may maintain a suitable low temperature and high humidity state, thereby allowing vegetables stored in the vegetable room to maintain freshness.
- Typically, a refrigerator 1 may include a
freezing chamber 20 and arefrigerating chamber 10 as illustrated inFIG. 1 , and also include afreezing chamber door 21 and a refrigeratingchamber door 11 for opening or closing the freezing chamber and refrigerating chamber, respectively. Furthermore, avegetable room 100 for storing vegetables and fruits (collectively, referred to as "vegetables") in a more fresh state is additionally provided at a predetermined location of the refrigeratingchamber 10. - The
vegetable room 100, as illustrated inFIG. 2 , may be provided with a drawer type, and may include acase 110 and adrawer 130 inserted into thecase 110 in a drawable manner. - The
case 110 is formed in a front side open state to open or close the vegetable room while thedrawer 130 is reciprocately inserted into a front side opening portion thereof that is open in a drawable manner . - The
case 110 is formed with a freezingchamber side plate 111, anoutside plate 112, anupper plate 113 and alower plate 114, and the rear surface thereof has a closed structure and the front side thereof has an open structure. - Accordingly, when the
vegetable room 100 is closed, the inner portion may preferably sealed from the outer portion to maintain a pressure lower than external atmospheric pressure, which activates a separate vacuum pump to allow the inner portion of the vegetable room to become a semi-vacuum state, thereby maintaining a pressure lower than atmospheric pressure. - In the refrigerator 1, the refrigerating
chamber 10 and freezingchamber 20 are sealed and divided by apartition wall 30, and thepartition wall 30 may be preferably formed not to transfer temperature from thefreezing chamber 20 to the refrigeratingchamber 10, thereby independently performing the function of each storage chamber. - However, as illustrated in
FIG. 1 , the left space of the refrigeratingchamber 10 located with thepartition wall 30 forms a temperature lower than that of the right side thereof due to the cool air (F) of thefreezing chamber 20.

FIG. 13 is a graph in which the internal temperature distributions of a vegetable room according to the related art and a vegetable room according to the present disclosure are measured, in particular, a graph in which the temperature distribution is measured in a state that theexternal metal plate 200 is attached to four surfaces (freezing chamber side, upper side, external side, rear surface) thereof. - Specifically, temperature distribution is measured in the condition of an internal temperature of 4 °C in a state that an inner portion of the vegetable room is made airtight.
- In case of the internal temperature of the vegetable room in the related art, the lower space of the vegetable room at the freezing chamber side (left) exhibits a very low temperature of about 1.8 °C, and the middle space of the vegetable room at the external side (right) exhibits a high temperature of 5.3 to 5.8 °C, thereby generating a severe temperature distribution imbalance.
- However, according to an embodiment of the present disclosure, it is seen that the freezing chamber side exhibits a relatively low temperature, but has a uniform temperature distribution compared to related art. In particular, it is seen that the external side (right) exhibits a temperature distribution of about 3.8 °C, and has a much more uniform temperature distribution compared the internal temperature distribution of the vegetable room in the related art.
- On the other hand, according to circumstances, the example including only an insulating material except the metal plate may be also taken into consideration.
FIG. 14 is a perspective view illustrating an embodiment of having only an insulating material, which is the same as the embodiment illustrated inFIG. 11 excluding that the metal plate is removed.FIG. 15 is a graph illustrating a temperature distribution in the embodiment illustrated inFIG. 14 in which temperature distribution is measured in the condition of an internal temperature of 4 °C after the inside of the vegetable room is made airtight. - Referring to
FIG. 15 , in case of the internal temperature of a refrigerator vegetable room simply formed with only ribs without attaching an insulating material thereto, the inner space of the vegetable room at the freezing chamber side (left) exhibits a very low temperature of about 1.8 °C, and the inner space of the vegetable room at the external side (right) also exhibits a low temperature of about 3.6 to 4.8 °C. - However, in case of a temperature distribution in which the internal temperature of the vegetable room is measured in a state that an insulating material (goldfoam, compressed styropor material) is attached on the rib, it is seen that the region has a far less temperature distribution region compared to a region in a state that the insulating material is not attached thereto even though the temperature of the freezing chamber (left) is about 1.8 °C.
