FR2793233A1 - Portable dispenser with optional chilling and heating facilities, for spring or mineral water, has selector block accommodating neck of inverted water bottle - Google Patents

Abstract

The block is divided by vertical partitions. The central section (A) has in an upper zone (A1), a fitting (1) that receives the neck of a commercially available bottle (2), and, in a lower zone (A2), a mains-fed transformer (17), providing a 12v operating supply. One side section (B) houses the chiller, the other, the heater (C). The sides and top of the enclosing case form a box, hinged about the lower front edge, that swings under the block, acting as a stand for the glass to be filled. Opt., the equipment is mounted on a fixed stand with a drip-tray. The bottle contents are released by a regulating valve (7) leading (10,11) into a transverse distribution tube (12). An inclined transfer tube (16) carries water thus released to an upper level for direct delivery or to be chilled or heated before delivery. A chilling element (19) cools water traversing a labyrinth (18) insulated (22) from the adjacent partition, then entering a buffer reservoir (20). On the other side (C), the hot water reservoir (27) is separated by the heater (28) from a similar labyrinth (29). User control buttons offer the three temperature options; the selected liquid falls into a common transverse channel with an outlet above the glass position.

Description

 The present invention relates to a low-voltage, mixed, compact, foldable and portable device for instant, refrigerated, heated or room temperature distribution of spring or mineral water from a commercial bottle for family or individual use.

 On the one hand, the design of traditional fountains is based either on the adaptation of the containers on a specific distribution device (bottles whose pellet is perforated by the receptacle), or on a direct connection to a water or liquid.

The few fountains using the bottles directly as containers are based on the same design as for the bottles and are relatively large and dedicated to communities.

 In addition, mixed devices are relatively expensive, bulky and noisy. Refrigeration is often carried out with gas compressor devices and heating is often carried out by a traditional electrical resistance. Consequently, they are not specially designed for rapid, transportable, light, individual and economical use.

 On the other hand, there are on the market, containers of mineral water of an increasingly large volume: five-liter water bottles with a relatively high weight and a large flow rate due to their wide neck.

 The device according to the invention overcomes this drawback. Its operating principle is linked to a device whose invention was deposited on February 4, 1999 by the same author: a cartridge regulating flow and pressure. Here are the main features as a reminder: -The cartridge grips or screws tightly to the neck of a bottle. This cartridge has a membrane with an orifice or central tube retaining an air pocket which provides the pressure necessary for the entire device. This air pocket is permanently supplied by an orifice. The membrane directs the liquid towards the conical tip of the cartridge, the opening of which is closed in a sealed manner by a valve which is also conical, kept pressed under liquid pressure or, and, by a flexible device. This tip is inserted into the bowl of the receptacle which follows its forms in a sealed manner. A protrusion surrounded by orifices and located at the bottom pushes the valve inside the end of the cartridge. The collected liquid is channeled to a distribution tube passing through the base of the receptacle under the protuberance.

 The device according to the invention comprises as a first characteristic a housing divided into three distinct zones (A, B and C) separated by a partition in the shape of an “H”. The upper part of the housing has a central opening for receiving the cartridge. The first zone is the room temperature zone (zone A), the second, the refrigeration zone (zone B), and the third, the heating zone (zone C). Zones B and C are connected by the cooling circuit. It can be perforated with ventilation holes on the front and rear at the level of zones A1 and A2 (ventilation).

 The central zone, zone A, is dedicated to drawing the water directly at room temperature and supplying the device. The central upper part of the partition made by the partition in the shape of an 'H', zone A1, is reserved for the location and the physical support of the cartridge receptacle from which the general distribution tube comes out), thus avoiding any direct contact with other areas except the connection tube connected to the refrigerated area. This distribution tube therefore allows, at the front of the device, the direct drawing of water at room temperature and, at the rear, is connected by a connection tube to the rest of the device. The lower part, zone A2, is reserved for the location of the electrical equipment (the transformer - which may possibly be autonomous outside the device - and the thermostat).

 In the refrigeration zone (zone B), a connection tube therefore connects the general distribution tube to the upper rear part of the vertical cascade refrigeration labyrinth tank. The latter is attached to a thermoelectric cooling module of the same dimension, there permanently pumping the heat. The heat is transferred to a cooling tank of the same size, or larger, which is permanently connected to the cooling circuit between zones B and C. An insulator helps to contain the cold (on the ambient temperature zone side). The outlet tube of the refrigeration labyrinth tank includes a connection with the outlet tube used for emptying the cooling tank and therefore with the entire cooling circuit. Its opening is actuated manually by a button to slightly unscrew in position 'A' (priming). The 'V' position controls the total emptying of the device. Position 'R' is that of the normal cooling circuit. This button is located on the cooling tank outlet tube.

 In the water heating zone (zone C), a water heating tank, narrow and of smaller size than the labyrinth refrigeration tank, is attached on one side to a thermoelectric heating module of the same size and on the other to an insulator helping to contain the heat (room temperature side). The thermoelectric module is itself joined in its second face to the labyrinth reservoir of the cooling circuit which is the same size as that of the refrigeration. The hot water comes out through a hole located at the upper end of the front face of the heating tank. The electrical supply of this thermoelectric heating module is manually operated to obtain hot water by a pressure switch placed behind the hot water distribution control button. It then pumps heat into the cooling labyrinth tank to heat the water in the heating tank. Another module can be attached to it in order to accelerate the rise in the heating temperature.

The water heating tank is supplied by a tube located at the lower rear and connected to the cooling tank in zone A, thereby drawing permanently preheated water from it around 50, the thermostat regulating the temperature by temporarily stopping the activity of the thermoelectric modules as soon as they are exceeded.

 The cooling circuit, directly using the water from the fountain, is supplied manually beforehand by passing through the labyrinth refrigeration tank (priming of the circuit), then, is supplied by call (suction) -in addition to the normal phenomenon of constant gravity facilitated by the orifice of the cartridge-when drawing hot water which draws the preheated water in the cooling circuit. The liquid thus withdrawn is immediately replaced by fresh water via another supply tube of the cooling circuit connecting the top of the labyrinth refrigeration tank-close to the arrival of the connection tube with the distribution tube general coming from the cartridge-and the top of the labyrinth cooling tank. This cooling circuit supply tube is preferably located at or above the air pocket of the cartridge so as not to be stressed during the normal cooling circuit. It thus facilitates the filling of the cooling circuit by becoming a withdrawal air pocket.

 A manual water distribution control device centralizes the four discharge ports: chilled water, room temperature water, heated water and general drain water, by communicating them through a network of pipes in one central distribution port. located at the central lower level on the front of the housing. A button to unscrew controls the opening of the general drain as well as the filling (priming) of the cooling circuit. It is located at the lower left end on the outlet tube of the cooling tank in zone B. The three distribution buttons are identical. In one piece, they each perform three different functions: 1) Closing the orifice with the pressure necessary for sealing. A conical closing end piece perfectly penetrating a plastic cylindrical end piece with also conical opening fitted onto the outlet tubes of the orifices. 2) The role of the spring developed by the elasticity of the form in 'V' wedged in its location so that in normal position a maximum pressure is exerted on the orifice. 3) The role of the button pushed back to the outside by the elasticity of the shape in 'V' which is rigid except at the level of the two articulations with the button. A pressure on this pushes the shape slightly in 'V' towards the only clear end located towards the closing end-piece, making so that it is at the same time moved back and reassembled, the point of the V shifting towards the latter . The water distribution openings at room temperature and heated, being at the top, at equal height, the two closing buttons are positioned in the same way upwards. With the chilled water distribution port positioned at the bottom, the button will be placed upside down. The three buttons are apparently external at the same level. The hot water pressure button simultaneously activates a switch supplying the thermoelectric heating module with manual pressure.

 The base of the device is retractable and is articulated on the lower front of the housing by rotation by means of a fitted hinge. In the 'closed' position, it becomes the housing cover and completely covers the front where the controls are located and the top, where the receptacle opening is located, housing the cartridge. it thus allows a transport reduced by half of the fountain with its cartridge, with better protection in terms of hygiene and controls. Only the rear wall and the underside are not covered by the cover.

 The thermoelectric modules are supplied by a low-voltage 12 Volt current via a transformer fixed in zone A2 ensuring maximum safety. A thermostat regulates the temperature to a maximum of 50 with a probe on the hot part of the cooling circuit thus temporarily cutting off the supply of the thermoelectric modules whatever the causes. A second safety switch (children) can be placed at the rear for a total shutdown of the central heating unit.

According to particular embodiments:
-The dimensions and volumes of the labyrinth refrigeration and cooling tanks, and simple cooling and heating tanks will be adapted according to the thermal conductivity of the materials chosen (alloys, aluminum, semiconductor plastics, etc.) as well as 'thickness of their walls (as thin as possible for the most immediate contact with water). These materials must be of 'food' quality. Different materials can be juxtaposed according to their performance, such as for connection tubes, for example.

 -The bulkhead in the form of 'H' shall combine resistance to weight (direct support for the receptacle and the bottle) and thermal insulation. Thick, cellular plastic seems to be suitable.

 -Tightness is particularly taken care of for zone A2 reserved for electrical equipment.

- The housing, as well as all the external elements, including the receptacle and the base can be made of the most diverse materials (plastic, stainless steel, aluminum, plasticized steel, etc. or a combination of these materials: (plasticized steel for the case and foot / cover, stainless steel for the receptacle). The base must be able to support the load of approximately 10 kilograms,
-The side walls of the housing which should participate as well as possible in the dissipation of heat from the cooling circuit can be applied to the tanks, preferably made of a material with good thermal conductivity and have an external surface facilitating the exchange with the ambient air ( like a radiator for example: ripples doubling the surface), Another alternative can be to create an airy space between the cooling tanks and the side walls of the box which can then be perforated with adequate ventilation openings .

 The three-function control buttons (button / spring / closure) can be produced in a single injection molding operation with two zones of reduced thickness forming the joints.

 The button to be unscrewed for draining and priming the cooling circuit can be replaced by any system with equivalent functions or offering additional security: for example, a button with automatic return to the closed position for the normal cooling circuit.

 -The housing, without the base, may be intended to become a module that fits into a larger fountain support with a traditional appearance for semi-collective use.

 -A child safety switch can be added to the rear of the device to interrupt the hot water plant.

 With reference to these drawings, the device comprises a cartridge regulating specific flow and pressure, the main characteristics of which are recalled below (FIG. 1): the cartridge (1) grips or screws in a sealed manner neck of a bottle (2).

This cartridge (1) comprises an orifice membrane (3) or central tube retaining an air pocket (4) which provides the necessary pressure. This air pocket (4) is permanently supplied by an orifice (5). The membrane directs the liquid towards the conical tip (6) of the cartridge (1), the opening of which is closed in leaktight manner by a valve (7) also slightly conical kept pressed under pressure of the liquid or, and, d 'a flexible device (8). This tip (6) is inserted into the bowl of the receptacle (9) which matches the shapes thereof in a sealed manner. A protrusion (10) surrounded by orifices (11) and located at the bottom pushes the valve (7) inside the end piece (6) of the cartridge (1). The collected liquid is channeled to a distribution tube (12) passing through the base of the receptacle (9) under the protuberance (10).

 The housing (13) is divided into three distinct zones (A, B and C) by a partition in the shape of an 'H' (14) (Figures 1,2 and 10). The upper part of the housing (13) has a central orifice (15) for receiving the cartridge (1). It is preferably perforated with ventilation holes on the front and rear at the levels of zones A1 and A2 in order to facilitate ventilation.

The central zone, zone A, which is dedicated to the direct drawing of water at room temperature and to the supply of the device (Figures 1,2,3 and 10) has a general distribution tube (12) which passes through and on the other the protuberance (10) at the base of the receptacle (9) in which the cartridge (1) is pressed. This general distribution tube (12) allows, at the front of the device, the direct drawing of water at room temperature (12 bis) and at the rear is connected by a connection tube (16) to the rest of the device (zones B and C). The central upper part of the partition made by the 'H' shaped partition (14), zone
A1, is reserved for the location and the physical support of the receptacle (9) of the cartridge (1) from which the generat distribution tube (12) comes out, thus avoiding any direct contact with the other zones except the connection tube (16) with the refrigerated part. The lower part, zone A2, is reserved for the location of the electrical equipment (the transformer (17) which can also be autonomous and external to the device - and the thermostat (17a)).

 The Refrigeration Zone (zone B) (Figures 1,2,4 and 10) therefore comprises the connection tube (16) connecting the general distribution tube (12) to the upper rear part of the refrigeration labyrinth tank with vertical cascades ( 18) which is attached to a thermoelectric cooling module (19) of the same dimension there permanently pumping the heat. The heat is transferred to a cooling tank (20) also of similar or larger size. This cooling tank (20) is permanently connected to the cooling circuit by two connection tubes: one at the lower rear (21) (arrival of the cooled liquid) and the other at the upper front (21a) ( return of the liquid to be refreshed). An insulator (22) helps contain the cold near the room temperature zone. The outlet tube (23) of the refrigeration labyrinth tank (18) has a connection (24) with the outlet tube (26) cooling tank (20) and the entire cooling circuit. Its opening is manually actuated by a unscrewing button (25) slightly in position 'A' (priming). The 'V' position controls the total emptying of the device. The 'R' position is that of the normal cooling circuit (closing the connection and outlet ports). This button (25) is located on the outlet tube (26) of the cooling tank (20).

 The heating zone (zone C) (FIGS. 1, 2, 5 and 10) comprises a water heating tank (27), narrow and of smaller size than the labyrinth refrigeration tank (18) which is attached to a next to a thermoelectric heating module (28) of the same size and on the other to an insulator (22 bis) helping to contain the heat (on the ambient temperature zone side). The thermoelectric module (28) is itself attached in its second face to a labyrinth cooling tank (29) of the same size as that of refrigeration (18). The hot water comes out through an orifice (30) located at the upper end of the front face of the heating tank (27). The electrical supply of this thermoelectric heating module (28) is actuated manually via the hot water distribution control button (31) by a pressure switch (32) placed under the latter.

It then pumps the heat into the cooling labyrinth tank (29) (occasionally contributing to its cooling) to heat the water in the heating tank (27). Another module can be attached to it in order to accelerate the rise in heating temperature. The heating tank (27) is supplied with preheated water via an orifice (33) located at the lower rear level by a preheated water supply tube (33) connecting it to the lower rear of the cooling tank (20) from zone A, thus drawing there a water which is preheated permanently which will be kept at around 50 by means of a thermostat (17a).

 The cooling circuit (Figures 1,2,9 and 10) is supplied manually beforehand via the refrigeration labyrinth reservoir (18) (priming of the circuit), then, is supplied by call (suction created by the vacuum) during the drawing through the hot water distribution orifice (30) drawing the preheated water in the cooling circuit. For this purpose, another supply tube for the cooling circuit (34) connects the top of the labyrinth refrigeration tank (18) - in an orifice close to the inlet of the connection tube (16)) with the distribution tube. general (12) coming from the cartridge (1) -and the top of the labyrinth cooling tank (29). This cooling circuit supply tube (34) is preferably located at or above the air pocket (4) of the cartridge (1) so as not to be stressed during the normal cooling circuit. It then serves as a 'withdrawal air bell' and facilitates the filling of the cooling circuit.

 On the front of the housing (13) (Figure 6) is located the manual water distribution control device centralizing the four discharge ports: chilled water (23), room temperature water (12 bis), heated water (30) and general drain water (26) by making them communicate by a network (35) of pipes in the same central distribution orifice (36) located at the central lower level, at the front of the housing (13).

 A button to unscrew (25) (Figures 6 and 9) controls the opening of the general drain as well as the filling of the cooling circuit (priming) or their closing for the normal cooling circuit according to its position (V, A or R ). It consists of a cylinder with a lateral opening juxtaposing either with the connection tube (24) with the labyrinth refrigeration tank (18) (position'A '), or with the evacuation opening towards the orifice of general distribution (36) for emptying (position 'V'). It is located at the lower left end on the cooling tank outlet tube (20) in zone B. The three distribution buttons: 'warm' (31), 'ambient' (37) and 'cold' ( 38) are identical (Figures 6,7 and 8). In one piece, they each perform three different functions: 1) Closing the orifice with the pressure necessary for sealing. A conical closing end piece (39) perfectly penetrating into a plastic cylindrical end (39 bis). the opening of which is also conical and which is fitted onto the outlet tubes.

2) The role of the spring developed by the elasticity of the shape in 'V' (40) wedged in its location so that in normal position a maximum pressure is exerted on the orifice (39 bis). 3) The roll of the button (31, 37 and 38) also repelled on the outside by the elasticity of the form in which V is rigid (40) except at the level of the joints (41) with the button. Pressing it pushes the 'V' shape (40) towards the only open end located towards the closing end piece (39), ensuring that the latter is both moved back and reassembled (rocking lever) , the tip of the V (40) shifting towards the closure end piece (39). The water distribution holes at room temperature (12 bis) and heated (30), being at the top, at equal height, the two buttons with closing 'hot' (31) and 'ambient' (37) are positioned the same way up. With the chilled water distribution port (23) positioned at the bottom, the 'cold' button (38) is placed upside down. The three buttons (31, 37 and 38) are apparently external at the same level. The hot water pressure button (31) simultaneously actuates an electrical switch (32) supplying the thermoelectric heating module (28) provided for occasional use under manual pressure.

 Finally, the retractable base (42) (FIG. 11) is articulated on the lower front of the housing by rotation by means of a fitted hinge (43). In the 'closed' position, it becomes the housing cover (13) and completely covers the front where the controls are located and the top, where the opening of the receptacle (15) is located, housing the cartridge (1). It thus covers the housing (13) on all of its faces except the rear and the bottom. It thus allows a transport reduced by half of the fountain provided with its cartridge, with better protection in terms of hygiene and controls.

 Without the retractable base (42), the device can be integrated into a more substantial support (44) (FIG. 12), of diversified shapes, making it possible to add a drip tray (45) and a grid (46) on it. a foot supporting the whole (47). A hanging support by simple clipping (48) will be provided for quick insertion and fixing. Air vents (49) will also be provided for internal lateral and vertical ventilation.

 The thermoelectric modules (19 and 28) are supplied by a low-voltage 12-volt current via a transformer (17) fixed in zone A2 ensuring maximum security. A thermostat (17) automatically regulates the temperature to an equilibrium temperature (for example 50), a probe being placed on the hot part of the cooling circuit. The thermostat momentarily cuts off the power to the thermoelectric modules (19 and 28) regardless of the causes of the temperature overshoot.

 The device of the invention is part of the family of small new generation household electrical appliances using new technologies (semiconductors). Space-saving, it can also without its retractable base, become the internal module of a fountain with a classic appearance. Depending on its version, it can be used both for camping or in the office, construction site, a patient's bedside, seminar, mopping, etc. offering mineral or spring water of your choice chilled or hot for tea, infusion or coffee. Its compact cubic shape and its lightness are assets for the economy of manufacture, storage and export.

 The manufacturing cost including the water cooling and heating system is considerably reduced thanks to the use of thermoelectric modules and its autonomous temperature regulation system by semi-closed cooling circuit using water from the fountain.

 The device using neither gas nor compressor is both ecological and quieter. It is more economical for its electrical consumption while offering the security linked to low voltage.
