Definitions
- This invention relates to a device in accordance with the introduction to the main claim.
- Refrigerators in particular forced air circulation refrigerators, have been known for some time provided with a chamber or drawer at a controlled temperature close to 0°C for containing food which has preferably to be preserved at this temperature, such as fresh meat and fish.
- Such chambers are generally provided between the preservation compartment and the freezer compartment.
- these are positioned in the upper region in proximity to the cold air ventilation ports present in the compartment.
- Each chamber comprises means for feeding the forced air into it and means for intercepting or throttling this air circulation when not required or desired (for example because the chamber temperature has reached the set value).
- Static refrigerators are also known provided with a chamber or drawer at controlled temperature for containing particular foods.
- NO-177365 describes a refrigerator the compartment of which contains several containers or drawers of the aforesaid type.
- a temperature sensor which, together with a usual sensor associated with the evaporator positioned in correspondence with said compartment, ensures correct operation of the refrigeration circuit such that different appropriate temperatures exist in said drawers for preserving the food placed in them.
- the temperature sensor associated with the evaporator causes the motor-compressor unit to operate only when an acceptable maximum temperature is attained at the evaporator during defrosting, whereas the other sensor positioned in proximity to the drawer or drawers controls the deactivation of the compressor to prevent the temperature in the drawer or drawers falling to a value incompatible with correct preservation of the item contained in it, for example potatoes.
- An object of the present invention is to provide an improved device for controlling the temperature within a chamber, positioned within the preservation compartment of a refrigerator, and used at a predetermined temperature for preserving particular foods such as fresh meat and fish.
- a particular object of the present invention is to provide a device of the aforesaid type usable in a static refrigerator, which achieves optimum control of the temperature within the controlled temperature chamber.
- a refrigerator for example a static domestic upright refrigerator, comprises a cabinet 1 containing a preservation compartment 2 and a freezer compartment 3 provided with their doors 4 and 5, defining two environments which are completely different from each other in terms of their internal temperature.
- a (flat) evaporator 7 connected to a compressor 8 in known manner.
- a control unit preferably of microprocessor type 9, controls the operation of the compressor 8 and consequently the temperature of the compartment 2 and of the freezer compartment 3.
- a controlled temperature chamber 10 for preserving meat, fish, dressed pork products or other (fresh) food requiring to be preserved at a temperature close to 0°C.
- This chamber is positioned above usual containers 11 (only one is shown in the figure) for containing fruit and vegetables.
- the chamber 10 is insulated both towards the freezer 11 and towards the compartment 2 by walls 12.
- An extractable drawer (not shown) is provided in the chamber 10, this chamber being closed frontally (ie towards the door 4) by a mobile door 13.
- the refrigerator uses internal shelves of grid type (not shown)
- there is associated with the chamber 10 a panel 15 positioned to the front of and parallel to said wall 6. In this manner, between this latter and the panel there is created a duct 17 for the air, which moves downwards by natural convection to graze the wall 6 (cold because of the evaporator) and become cold.
- the duct 17 passes along the compartment 2 and communicates with the rear part 18 of the chamber 10, to allow said cold air to enter this latter.
- a temperature sensor 20 connected to the unit 9, which by means of the data originating from said sensor 20, controls the operation or deactivation of the compressor 8, as described hereinafter.
- the unit 9 is also connected to a pushbutton 21 provided on an interface 22 positioned on the cabinet 1 and comprising, in addition to said pushbuttons, further pushbuttons 23, 24, 25, 26, 27 and 28.
- the pushbutton 21 is arranged to select the use of the chamber 10 as a temperature controlled chamber or not, and consequently to select at least two different operating modes of the unit 9, as described hereinafter.
- the pushbutton 23 controls the cold in the preservation compartment, in correspondence with it there being provided a light-emitting indicator 30 indicating the operation or non-operation of the refrigerator.
- the pushbutton 24 enables the required temperature to be selected in the preservation compartment 2 and be displayed on a display 31.
- the pushbutton 25 controls the cold in the freezer compartment 3, in correspondence with it there being provided a light-emitting indicator 33.
- the pushbutton 26 enables the temperature in the freezer compartment to be selected, and displayed on a display 34.
- the pushbutton 27 activates fast freezing, the relative light-emitting indicator 35 being provided in correspondence with it.
- the pushbutton 28 excludes an acoustic alarm which is activated when the temperature in the freezer compartment 3 reaches an undesired predetermined value (for example too high); with this pushbutton there is associated a relative light-emitting indicator 36 indicating that a critical temperature has been reached in the compartment 3.
- an indicator 38 indicating whether the user has selected the chamber 10 as a temperature controlled chamber or not; if the selection is not made, then the temperature in the chamber is substantially not ideal for meat and fish, but suitable for other uses typical of a refrigerated compartment.
- the pushbutton 21 it is also possible (for example by maintaining it pressed for a predetermined time period) to indicate to the unit 9 the presence or absence of the drawer within the chamber 10, this condition being displayed (indicated by 40) on the display 31.
- the refrigerator according to the invention is to be used, but without wishing to use the chamber 10 as a temperature controlled chamber set at around 0°C.
- the pushbutton 21 is not pressed, and the user can select the required temperature in the compartment 2 and in the compartment 3.
- the unit 9 measures the temperature via the sensor 20 and operates on the compressor to achieve the desired temperature in the compartment 2. This is obtained by comparing the values measured by the sensor 20 with a range (or first range) of temperatures; on the basis of the temperature of the compartment 2 (indicated in the portion A of the table of Figure 3) and the temperature measured by the sensor 20, the compressor is halted when the temperatures indicated in the portion B of said table are achieved. For example, as shown, eight possible temperatures can be obtained in the compartment 2.
- the unit 9 operates to compare the temperature measured by the sensor 20 with another (or second) range of temperatures (having a value less than that of the first range and shown in the portion C1 of the table of Figure 3).
- the temperature desired in the chamber 10 can be close to 0°C if the food placed in the chamber 10 is fresh, or can be slightly less than 0°C for other foods. All this can be selected via the pushbutton 21 by successively pressing it.
- the operability of the chamber 10 is however limited to just a few temperatures. If the user sets too high a temperature (exceeding 5°C) for the preservation compartment 2, the unit 9 automatically passes to the configuration indicated by C2 in table 3, in which the temperature in the chamber 10 is the usual temperature for a preservation compartment.
- the unit 9 can operate up to nine temperature levels, the last corresponding to a relatively high temperature (for example 6.5°C) in the chamber 10.
- an optimum and reliable setting of the temperature within the chamber 10 can be achieved when it is desired to use it as a temperature controlled chamber.
- the invention can be applied to any refrigerator comprising at least one compartment (and even just one compartment such as frigobars) in which a controlled temperature chamber is to be formed.
- a controlled temperature chamber is to be formed.
