Definitions

  • the present invention relates to cooling appliances, and in particular to cooling appliances comprising a device for controlling humidity in the vegetable compartment.
  • JP 05302781 describes a housing located in the top part of the vegetable compartment where a component is housed for controlling the humidity.
  • Said component comprises a permeable element in laminar form, such as non-woven polyester fibre, a superabsorbent polymer that maintains humidity levels and a hydrophilic component such as silica gel.
  • JP 2001091144 discloses an element, also located in the top part of the vegetable compartment, for controlling humidity, which comprises a gel-organic material in the form of fine particles that are hygroscopic.
  • the vegetable compartment of the invention incorporates a device for controlling humidity.
  • Said device comprises:
  • Said hygroscopic material and said humidity transfer wall are disposed in a substantially vertical position.
  • the hygroscopic material is in contact with a water tank, which thus guarantees that the hygroscopic material always contains a sufficient level of humidity and may thus release it into the vegetable compartment.
  • Figure 1 shows an embodiment of the vegetable compartment 100 for a cooling appliance that incorporates a device 1 for controlling humidity.
  • Said device comprises:
  • the hygroscopic material and the humidity transfer wall 9 are disposed in a substantially vertical position, where the hygroscopic material is in contact with a water tank.
  • the humidity control device 1 is built into a divider, in other words, said device 1 is configured in such a way that it also performs the function of a conventional vegetable compartment divider.
  • Other arrangements are also possible, however, such as those in which the humidity control device 1 is built into some of the side walls or even in the front of the compartment 100.
  • the hygroscopic material used can be any insoluble material with humidity-absorption properties.
  • the hygroscopic material used is a superabsorbent polymer, such as a polyacrylate polymer, which is disposed inside a permeable fabric bag 10 that is located, as shown in Figure 3 , between the transfer walls 9.
  • an antibacterial agent is added in the fabric of the permeable bag.
  • the water tank 8 is located in the base of the humidity control device 1, and is situated beneath the hygroscopic material.
  • the hygroscopic material is in contact with the water tank 8, the hygroscopic material always contains a sufficient level of humidity and may thus release it inside the compartment 100.
  • Said water tank 8 comprises an enclosed area 11 in which is disposed one end of the hygroscopic material, said enclosed area 11 being separated from the rest of the water tank 8 by means of a wall with a plurality of grooves 13. These grooves are shown in Figure 5 .
  • the humidity control device 1 of the invention also comprises a base body 6 which also comprises holes 14, shown in detail in Figure 6 .
  • a base body 6 which also comprises holes 14, shown in detail in Figure 6 .
  • the grooves 13 and the holes 14 are positioned at par, as shown in detail in Figure 6 .
  • this embodiment can regulate and control the passage of water from the water tank 8 to the enclosed area 11 and guarantees a contact between the water and the lower surface of the hygroscopic material.
  • the hygroscopic material which is in contact with the water tank 8, and more specifically with the water contained in the enclosed area 11, absorbs the water from the enclosed area 11, with the result that it can release said humidity through holes disposed in the transfer wall 9.
  • any hygroscopic material that is capable of absorbing water from the water tank 8 and transfer it into the compartment 100.
  • Using a superabsorbent polymer can get also, when necessary, that said superabsorbent polymer absorbs humidity from the inside of the compartment 100 through the transfer wall 9.
  • the humidity control device 1 also comprises an inlet pipe for filling the water tank 8.
  • Figure 4 shows a cross-section of it.
  • Water is supplied to the humidity control device 1 using a dispenser cup 2, which is housed with its mouth facing down on the inlet pipe.
  • the water is poured on to a funnel 3, which is housed on a filter holder 5.
  • the funnel 3 has holes disposed in its lower part, these also being partly visible in Figure 4 , to allow the water to pass to the filter holder 5.
  • the water is filtered in said filter holder 5, where an organic material 16, also shown in Figure 4 , is deposited previously to ensure the quality of the water.
  • the filter holder 5 in the lower part is also disposed with holes (not shown in the drawings) to allow the water to pass into the water tank 8.
  • a permeable element 4 is positioned in both the lower part and the top part of the filter holder 5, in order to keep the organic material 16 inside the filter holder 5 as shown in Figure 5 . As a result, the organic material 16 is retained inside the filter holder 5.
  • the humidity control device 1 of the invention also comprises a level gauge 7, shown in Figures 2 and 7 .
  • Said level gauge 7 is supported on an auxiliary permeable fabric bag 15 as shown in Figure 7 , which contains hygroscopic material in its interior and is located in an enclosed area 12, shown in Figure 5 , which contains water from the water tank 8.
  • the word "OK" is included in the top part of the level gauge 7.
  • the variation in the volume of the hygroscopic material that is inside the auxiliary permeable bag 15 is proportional to the amount of water supplied to the water tank 8.
  • said hygroscopic material absorbs water from the enclosed area 12, it swells up and increases in height.
  • the level gauge 7 moves in a vertical direction pushed by the auxiliary permeable bag 15.
  • the humidity control device 1 of the invention is sufficiently hydrated and may thus provide the vegetable compartment with the necessary humidity to ensure the food is kept in optimum humidity conditions.
  • the humidity control device 1 of the invention comprises two substantially vertical dividing walls that delimit the housing of the hygroscopic material as shown in Figure 3 .
  • both dividing walls are humidity transfer walls 9.
  • other embodiments are possible, such as one of said dividing walls being used as the humidity transfer wall 9.
  • the humidity control device 1 of the invention can be extracted, thereby making it easier to maintain and clean.
