The present invention relates to controlling the moisture and temperature of the content of a container. More specifically, it is directed to a modular assembly that comprises a moisture and temperature regulating device, and a container, where the moisture and temperature regulating device and the container are separate but joinable by coupling means. When the moisture and temperature regulating device and the container are joined, moisture and temperature associated with the container are regulated by the moisture and temperature regulating device.
As the world population increases, the amount of household trash produced each year also increases. Studies estimate that in 2013, each person produced more than 4 pounds of waste each day. Municipalities have attempted to come up with various strategies to efficiently deal with waste disposal.
Across the municipalities in North America, household garbage is collected, typically only on a weekly basis, by curbside pickup of organics compostable contained in paper bags. As a result, household garbage accumulates over the week waiting to be collected. As a result, kitchen garbage, which contains, in large part, organics compostable, starts to decay. In warm and hot weather, waste decay typically accelerates, and garbage odors become an issue.
Garbage odor can cause the entire house to smell unpleasant. To control garbage odors, various methods have been used, for example, by sealing the garbage container to prevent odor from flowing outside, using baking soda, cat litter or other chemicals to prevent odors, using drying sheets to absorb the moisture in garbage containers and prevent odors, putting garbage in colder places to suppress odors, etc.
There remains a need however, to effectively regulate moisture and temperature of contents in garbage containers.
It is well known that bacteria, fungi, and other microorganisms break down the organic material inside the garbage. Microorganisms that live in temperatures from 10° C.-45° C. begin the decomposition process. The microorganisms generate heat as they consume and digest the content in the garbage container. As the garbage content heats up, other microorganisms that live in temperatures from 45°-70° C. take over the decomposition process.
The bacteria that decompose the garbage content require moisture and oxygen. If the garbage content is low in humidity, or if bacteria use up the available oxygen, the temperature drops and the decomposition process slows down.
Therefore, by regulating the moisture and temperature of the content in garbage containers, households can effectively control waste decay and in turn garbage odor.

Dehumidifiers are known. In a standard dehumidifier, a fan draws in humid air and carries it through a refrigerated evaporator. The air is cooled below its dew point. The moisture from the humid air condenses on the cold surface of the evaporator and drips into a water container or is led directly to a drain. Then the cold dry air continues through a hot condenser which heats it up and returns it to the room to pick up new humidity. This procedure is continued until the desired condition is achieved. In this type of dehumidifiers, evaporator and condenser are in the same space where cooling of moist air condensation, heat exchange between moist air and condenser occurs.
In contrast to the standard dehumidifier, in accordance with the present invention, in moisture and temperature regulating unit 12, the cooling are separated by a heat insulation layer 34 so that there is no heat exchange between moist air and the condenser, as described below.
Referring to
In a preferred embodiment, portable container 13 is further equipped with a cover 42. Cover 42 is rotatable along the cover pivot axis 47. Shown in
One side of the housing body of the garbage container, preferably vertically up along the cover pivot axis, is coupling plate 43. The coupling plate 43 has an upper ventilation outlet 44 and a lower ventilation inlet 45, wherein the ventilation outlet 44 is positioned above the ventilation inlet 45. Air inlet 25 of moisture and temperature regulating unit 12 and upper ventilation outlet 44 of the container are at the same height and of the same or similar size; they are joinable by coupling means. Air outlet 27 of moisture and temperature regulating unit 12 and lower ventilation inlet 45 of container 13 are at the same height and of the same or similar size; they are joinable by coupling means.
