FR2538691A1 - DEVICE FOR AUTOMATIC LIFTING OF THE COVER OF THE POTS - Google Patents

Abstract

THE INVENTION RELATES TO A DEVICE ADAPTED FOR AUTOMATICALLY LIFTING THE LID OF A KETTLE WHEN THE CONTENTS OF THE latter REACH A DETERMINED TEMPERATURE. THIS DEVICE CONSISTS OF A FRAME 1 WHICH CAN BE MOUNTED ON THE INSIDE EDGE OF A POT, A THERMOSTATIC VALVE 4 BEING PROVIDED IN THIS FRAME. THIS VALVE INCLUDES A CENTRAL CYLINDRICAL BODY 5 MAINTAINED LOWERED BY A BUCKLE SPRING 6. WHEN A PREDETERMINED TEMPERATURE IS REACHED, THE CYLINDRICAL BODY 5 MOVES UPWARD, LIFTING A SMALL ARM 7 WHICH SUPPORTS IT MANEALLY COVER IT CONTENTS OF THE POT DOESN'T OVERFLOW.

Description

i 1 2538691

  The invention relates to a device which automatically lifts

  the lid of a pot when its content reaches boiling point This device, very inexpensive, can be mounted on n

  any type of pot by adapting it to the edge thereof

  The device according to i nyentivn belongs to the range of accessories

  kitchen evenings solving one of the many little problems that the me-

swimmers meet each day.

  Indeed, each time a housewife places a pot on the stove, she must be careful until the contents boil and, then, lift the lid a little when the boiling begins, to prevent the contents from overflowing The present invention, to solve this problem, provides a very simple device which automatically lifts the cover a small distance from an edge, as soon as the temperature inside the pot reaches the boiling point.

  uses a thermostatic element to perform this function This element

  mounted on the lid or on the edge of the pot, turns an arm when the temperature reaches a predetermined level - This arm applies

  at the cover a force as a result of which it lifts slightly.

  Other characteristics of the invention will appear from the

  following description of an embodiment given by way of example not

  limiting and shown in the accompanying drawings, in which: Figure 1 is a sectional view on a pot on which is mounted the device according to the invention, the cover being closed; Figure 2 shows the same components as in Figure 1, the

  lid of the pot being lifted.

  The device according to the invention consists of a frame

  1 essentially formed by a C-shaped element 2, preferably fa-

  made of cut and folded sheet metal, closed by a plate 3 made of the same

  material and fixed in a known manner to element 2 Elements 2 and 3

  form a seat body of a thermostatic valve 4 of known type, including

  me the ones we use on car radiators.

  The thermostatic valve 4 comprises a central body 5, generally

  generally cylindrical, which is held lowered by a coil spring or other device 6, as seen in Figure 1, but which can exit from the element 2 through a hole provided in its upper part and

not visible on the drawings.

  The thermostatic valve 4 is designed so that, when it reaches a determined temperature, the cylindrical body 5

moves up.

  A rod 7 or a similar device is articulated

  above C-shaped element 2 and preferably attached to two ears

  the 8 formed, for example, by folding up two edges of the

  element 2 Furthermore, a hook 9 or similar arrangement is fixed in a known manner to the element 2 on the side opposite to the ears 8 and is adapted to snap onto the edge of the pot to serve as support for the device. This device works as follows: We use the hook

  9 to mount the device described on the edge of a pot, the device

  tif being completely inside of it The state of the thermostatic valve at room temperature is such that the cylindrical body is entirely contained in the seat formed by elements 2 and 3 Consequently, the arm 7 is in a lowered position as shown in the figure

  1 and rests on the edge of the pot, its end being free.

  When the temperature inside the pot reaches the

  preset level to which the thermostat valve has been previously set

  that, it follows that the body 5 moves outward, compressing the spring 6 The end of the body 5 then acts on the arm 7, causing it to rotate slightly 6 around its hinges, which means that the cover lifts (Figure 2) Obviously, the type of thermostatic valve should not be limited to the type described, but may include various types of valve such as double sheet types, etc. Obviously, the dimensions as well as the materials used can vary according to operational requirements.

  1. Molding device Ment auton Mati'que of the neck of a pot when the content of the latter reaches a determined temperature,

  characterized by the fact that it includes a frame (1) fitted with an element

  ment (9) in the form of a hook making it possible to mount it on the edge of a pot, inside of it, this frame (1) supporting inside

  a thermostatic element (4) designed to control, when the temperature

  determined strike is reached, the lifting movement of an arm (7),

  cover port 2. Device according to claim 1, characterized in that the thermostatic element (4) comprises a body (5) which causes, when the predetermined temperature is reached, against the opposing elastic force of a spring ( 6), the movement of the arm (7) designed to act on

  the lid of the pot, directly or through a mechanism

  lever lever, so that this cover is lifted.
