Description

DESCRIPTION

Home appliance

TECHNICAL SECTOR

The present application refers to a domestic appliance, mainly for refrigeration or freezing, but applicable to any product that maintains a controlled indoor environment, with temperature, humidity or pressure conditions different from the outside. It offers a measure to save energy and to improve the preservation of food or products.

STATE OF THE ART

Often times, refrigerators, fridges, freezers and other controlled environment appliances have a weak point in the loss of interior conditions when the corresponding door is open, especially if it is left open by mistake. This case implies an increase in energy expenditure and an increased risk of loss of internal products, normally food, due to inadequate storage conditions.

To reduce this risk, most manufacturers set an alarm that warns of the open position of the door after one second. However, if the user is older, busy, or has walked away, they may not hear that alarm.

The applicant does not know of any type of device that allows solving all these problems as simply as the invention.

BRIEF EXPLANATION OF THE INVENTION

The invention consists of a household appliance according to the first claim. Its different variants solve the problems outlined.

The appliance is of the type that maintains specific temperature, pressure or humidity conditions in the interior environment of one or more cabinets. For example, it can be a refrigerator, freezer, wine cellar, food dehydrator, etc.

The domestic appliance is of the type that comprises one or more cabins with an environment controlled in pressure, temperature and / or humidity. Each cabin has one or more doors fixed by one or more hinges. Furthermore, according to the invention, it comprises a door return mechanism, generally motorized, and with a delay, which can be disconnected.

Preferably, this delay is adjustable by means of a knob. Furthermore, it may comprise a second mode of operation with a considerably longer delay (on the order of one or more minutes, instead of about 5-20 seconds).

Other variants can be seen in the rest of the report.

For a better understanding of the invention, the following figures are included.

MODES OF EMBODIMENT OF THE INVENTION

An embodiment of the invention will be briefly described below, as an illustrative and non-limiting example thereof.

Figures 1 and 2 show an embodiment consisting of a domestic appliance (1) with a series of cabinets (2), which can be a refrigerator, with an associated freezer or not, without being relevant to the invention. In any case, each cabin (2) of the domestic appliance (1) has a door (3) attached to the body of the domestic appliance by means of one or more hinges (4).

The doors (3), at least those that give access to the cabin (2) with stricter conditions (greater difference in temperature, humidity or pressure with the outside environment), have a return mechanism (5), which will generally be motorized . This return mechanism (5) can be arranged on at least one hinge (4) or be independent. The return mechanism (5) has a delay programmed in its control unit (6), so that the closure takes place after a few seconds. This delay can be adjusted using a knob (7). Likewise, the knob (7) can restart the delay countdown.

Likewise, it is desirable to be able to stop or disconnect the return mechanism (5) if it is desired to have the door (3) open for a long time, or to define a second operating mode in which the delay time is considerably greater than usual. The disconnection or the second operating mode will be abandoned after a time or each time the corresponding door (3) is closed.

For example, the return mechanism (5) can be configured to close the corresponding door (3) after 5-20 seconds, and the second mode of operation can lengthen the time to 40-120 seconds. The delay time will depend, among other things, on the type of appliance. Thus, a refrigerator will close with a longer delay than a freezer.

The return mechanism (5), the control unit (6), the knob (7), can be on the inside wall of the cabin (2), as shown in figure 2, on the door (3) , distributed between the two ... without it being especially relevant.

Claims (1)

1- Domestic appliance comprising one or more cabins (2) with an environment controlled in pressure, temperature and / or humidity, with respective doors (3) fixed by one or more hinges (4), characterized in that it comprises a return mechanism (5 ) with delay. 2- Home appliance, according to claim 1, characterized in that the. Return mechanism (5) is motorized. 3- Home appliance, according to claim 1, characterized in that the delay is adjustable by means of a knob (7). 4- Home appliance, according to claim 1, characterized in that it comprises a second operating mode with a longer delay. 5- Home appliance, according to claim 1, characterized in that the return mechanism (5) is disconnectable. 6- Home appliance, according to claim 1, characterized in that the return mechanism (5) is part of a hinge (4).
