Description

The present invention relates to the field of household appliances, more specifically to transport liquids, especially water, such as hairdressers, especially hairdressers that use steam to optimize hairdressing. Regarding hairdressing equipment equipped with the system of.

Such hairdressers include a housing that includes a liquid transport system and / or a liquid storage system and at least one electrical or electronic component.

Patent Document 1 of the current technique provides an example of the use of steam to improve the effectiveness of hair straighteners, in particular hair straighteners. For example, as described in this document, the hair straightener is a hair straightener with one branch, including a liquid reservoir, a vaporization system, and a system for releasing vapor towards the hair. It is a form. According to this example, the liquid is carried to the vaporization system by capillarity by the core carrying the liquid.

Further, the use of a peristaltic pump in a hairdressing device for transporting a liquid from a reservoir is particularly known from Patent Document 2. In particular, this document teaches the use of a peristaltic pump that regulates the flow of a liquid to supply the liquid to a means of vaporizing the liquid. Therefore, according to the instruments described in this document, the peristaltic pump makes it possible to transport liquids, especially water, to produce steam.

Other devices, such as those described in Patent Document 3, disclose the use of reservoirs within the housing of hair conditioning devices so that they can generate steam for use in hair.

These various structures generally give satisfaction to the users of the instruments discussed, especially when it comes to the performance and hairdressing results obtained.

However, both of these structures pose a danger in the presence of any leaks. In fact, at least one of the branches includes a vaporization system and one or more liquid transport devices such as pipes, ducts, wicks, or pumps. In addition, as in the case of the first document referenced, one of the branches of the instrument also comprises a liquid reservoir. In other words, the hairdresser comprises at least one liquid transport system, or several liquid-containing elements, within its housing. Therefore, there is a serious risk of leakage. For example, the connection between the reservoir and the hose that connects it to the vaporization system can be defective (loose connections, worn connectors, etc.) and can leak. The hose can also be detached, for example due to overpressure caused by calcification in the instrument, and the hose itself can have defects (perforations, tears, etc.). The reservoir itself can also have defects (eg, post-impact perforations, cracks, etc.), allowing liquid to leak. If the appliance has a pump, it can also fail and allow liquid to leak. Therefore, within one of the branches of the instrument, there are several causes that may result in a liquid leak.

However, the presence of liquids, especially water, inside this type of device is not desirable. In fact, these appliances are usually electrical appliances, at least as long as they include a heating element for electrically heating the hairdressing surface, or various electrical and electronic components. As a result, the presence of liquid inside these instruments destroys their electrical and / or electronic components, thus resulting in malfunction or complete failure of the hairdressing instrument. Moreover, in particular, since these are handheld devices operated in the immediate vicinity of the user's head, the risk of electrocution for the user cannot be completely eliminated.

Therefore, there is a need to make this type of device safer, whether for the components of the device itself or for the user.

International Publication No. 2004/002262 European Patent No. 2449910 U.S. Pat. No. 4,341,229 European Patent No. 2499909 European Patent No. 2499912

An object of the present invention is to overcome the above-mentioned drawbacks.

One object of the present invention is to provide a hairdressing device that is particularly safe, whether for the electrical and / or electronic components of the device itself, or for the user who handles the device.

Another object of the present invention is to provide a particularly reliable and robust hairdressing device.

Another object of the present invention is to provide a hairdressing device that is particularly simple to manufacture and inexpensive.

Another object of the present invention is to provide a particularly effective hairdressing device.

Objectives are achieved using a hairdressing device, including a housing, comprising a liquid transport system and / or a liquid storage system and at least one electrical or electronic component, the housing being a liquid transport system and / or a liquid storage system. Includes a liquid drainage system designed to drain liquid from the housing in the event of a liquid leak from, the drainage system is arranged so that the liquid cannot come into contact with at least one electrical or electronic component. It is characterized by that. Accordingly, according to the present invention, the hairdressing device is a liquid transport system, eg, a mechanical action by a pump, or a capillary action by a wick, or a gravity action, such as a simple flow through a hose, or one of ordinary skill in the art. Includes any system capable of transporting a liquid by any other means known to, or any combination of these means. Alternatively, or in addition, the instrument that is the subject of the invention includes a liquid storage system, such as a reservoir for accommodating liquids, preferably water. However, without departing from the scope of the invention, it could be assumed that the reservoir could also optionally store cosmetics diluted with water.

The present invention provides a system for the designer to drain any liquid that may inadvertently or accidentally enter the interior of the housing when designing the appliance, for example. To ensure that the operation of the instrument is substantially safe, as long as it occurs in a controlled and well-thought-out manner, by precisely controlling the discharge trajectory of the liquid and / or the exact location where the liquid is discharged. Enables. In other words, the invention is therefore capable of draining any liquid that may accidentally enter the housing before the liquid comes into contact with electrical or electronic components. Therefore, any accidental contact between the liquid and this component is substantially avoided and the safety of the device and the user is greatly improved. In fact, even if not completely eliminated, electrical or electronic components are unlikely to be damaged and the risk of electric shock by the user is greatly reduced.

Such control of the drainage of all liquids, which may be abnormally present in the housing of the hairdresser, allows the liquid to pass through the only opening available to it, usually between several parts. It constitutes a very important difference compared to conventional instruments, which escape through gaps, especially between the housing and one of the orthodontic plates of the instrument. However, this is a particularly sensitive region as the region contains power components, heating elements of the straightening plate, so that the liquid subsequently comes into contact with the electrical components.

It will be easy for those skilled in the art to verify the results of the present invention by a simple test. For example, he / she could pierce or extract (ie, detach) the liquid transport system to simulate a leak of liquid in the housing. One of ordinary skill in the art would only need to handle the hairdresser in a different position, as he / she would do during normal use. One of ordinary skill in the art would then be able to check if the liquid actually flows through the drainage system. One of ordinary skill in the art also knows whether the liquid has come into contact with the electrical or electronic components of the device, eg, by disassembling the housing of the device, that is, whether the liquid has come into contact with the components when the device is handled. You will be able to check if. Such verification is simple as long as the components being discussed will exhibit significant damage (burning, corrosion, explosion, etc.) when in contact with a liquid.

Advantageously, the liquid drainage system comprises at least one opening, preferably two openings, through the housing. This makes it possible to control and advantageously increase the liquid discharge flow rate in a particularly reliable and inexpensive way. The opening can be of any shape. However, the at least one opening is preferably a hole having a diameter between 0.5 mm and 4 mm, preferably between 1 mm and 1.5 mm. If more than one opening is given, the exhaust section is advantageously configured between 1 mm ² and 4 mm ² , preferably between 2 mm ² and 2.5 mm ² .

Advantageously, the liquid discharge system is permanently open to the surroundings, in this case the atmosphere. In other words, the liquid drainage system has no plugs or other obstructing or sealing elements.

According to an advantageous embodiment, the appliance comprises a first bifurcation and a second bifurcation connected to each other by hinges to form a hairdressing iron. Therefore, the instrument forms a straightening iron that allows for excellent ease of use and optimal hair straightening results.

In the first modification of the previous embodiment, the housing is formed by the first bifurcation. In other words, not only the liquid transport and / or liquid storage system, but also at least one electrical or electronic component is incorporated in the first branch, which makes it possible to obtain a relatively compact hairdresser. do. Generally, the first bifurcation is designed to be grabbed by the user's hand and easily manipulated by the user near his / her head.

According to this first variant, the first bifurcation preferably comprises a reservoir and a first surface for treating hair by contact, and the liquid drainage system comprises a reservoir and a first treated surface. Placed between and. Such an arrangement makes it possible to have a particularly compact hairdressing device. In addition, the placement of the drainage system between the reservoir and the first treated surface prevents the first treated surface from accidentally coming into contact with any liquid that may be inside the bifurcation. Allows it to prevent liquids from coming into contact with the hair. It is also particularly useful and safe when the first treated surface is a surface heated by an electrically heating element (eg, PTC). Advantageously, the liquid discharge system is located at a distance of between 10 mm and 50 mm, preferably between 20 mm and 30 mm, from the edge of the first treated surface. This makes it particularly possible to maintain a safe distance from the first treated surface, especially from its electrical heating element.

In a second variant of the same embodiment, the housing is located away from the first branch and is connected to the first branch by a cord. This configuration makes it possible, for example, to provide a larger housing for incorporating larger liquid transport systems (eg pumps) and / or large capacity liquid storage systems because it is powerful. do. And in this case, the housing is generally intended to be placed on a work surface, such as a table, to prevent it from moving, but the first branch is movable and is handled by the user. .. According to this variant, the first bifurcation includes a first surface for treating hair by contact, the housing contains a reservoir, and the liquid drainage system is located between the reservoir and the treated surface. Will be done. As mentioned above, the drainage system may further include at least one opening through the housing. However, it is also entirely possible that the branch, alternative or additionally, includes the above-mentioned opening or another opening of another discharge system. In fact, according to this variant, the liquid is stored or transported within the housing (ie, base) and branch. Therefore, in order to optimize the safety of the device, it may be wise to place the discharge system according to the invention in the housing and another discharge system according to the invention in the branch. Therefore, according to this variant, in the case of a liquid leak at the base, the liquid is discharged in a controlled manner so that the liquid cannot contact the electrical or electronic components of the base, and in the case of a liquid leak at the branch. The liquid will be discharged in a controlled manner so that the liquid cannot come into contact with the electrical or electronic components of the branch.

The term "treated surface" as used above refers to any type of surface from the time of contact with the hair at at least one place, regardless of its shape, size. The treated surface can be, for example, formed by a single moiety and can be continuous, or vice versa, eg, formed by multiple moieties and can be discontinuous.
As a non-limiting example, the processing surface
-For example, formed by a straightening plate, smooth and flat,
-For example, formed with a mandrel, roller, or flat iron, smooth and curved,
-For example, wavy, including a series of depressions and ridges,
-Rough, including, for example, bristles and teeth
-And so on.

According to an advantageous embodiment of the invention, the liquid transport system comprises a perturbing pump body that defines a chamber in which a deformable hose intended to contain the liquid to be moved is present. , As well as a liquid outflow system designed to drain liquid from the chamber to the outside of the pump according to a controlled trajectory in the case of a rupture of the deformable hose of the pump, in which the liquid outflow system. Communicate with the discharge system. Advantageously, the liquid outflow system includes at least one hole that allows control of the liquid flow trajectory in a very economical and safe way. "Controlled orbit" means that the place where the liquid flows out, i.e., flows out through it is pre-defined by the designer. In other words, exactly where and how the liquid will flow out is known. Advantageously, the diameter of the hole is composed of between 0.5 mm and 4 mm, preferably between 1 mm and 1.5 mm. Advantageously, the liquid outflow system comprises two holes and is advantageously arranged in close proximity to each other, separated by a distance consisting of, for example, between 1 mm and 5 mm, which is the flow rate and thus the outflow rate. Allows to increase. The presence of multiple holes makes it possible to ensure that the pump will be empty even if one of the holes is blocked. Therefore, the total discharge section is included between ² mm ² and 2.5 mm 2.

"Rupture of a deformable hose" means any deterioration that can lead to loss of watertightness of the hose, i.e., leakage of liquid contained in the deformable hose. For example, this is the result of burst hoses, split hoses, pierced hoses, excessive porosity of hoses, or, for example, accidental disconnection or removal of hoses after overpressure with lime in the instrument. possible. "Chamber" refers to any three-dimensional space intended to contain at least one element, in this case a deformable hose in a pump.

Therefore, according to this embodiment of the invention, in the event of an unexpected or accidental presence of a liquid in a pump, the liquid follows a trajectory pre-controlled by the designer and is pre-defined specific. It is quickly discharged to the location and therefore avoids accidental contact between the liquid and electrical or electronic components. More specifically, the liquid is first discharged from the pump to a specific location selected by the liquid outflow system and then discharged from the equipment by an outflow system that communicates with the pump outflow system. Therefore, the spill system and the spill system communicate with each other by any watertight means. For example, a pump outflow system may be connected to the equipment's drainage system by a pipe or outflow system, and the drainage systems may be connected to each other, eg, up and down.

Advantageously, the liquid outflow system penetrates the pump body.

Advantageously, the peristaltic pump includes a lid that works with the pump body, and the liquid outflow system can be passed through the lid. And this structure makes it possible to provide a peristaltic pump whose assembly and / or arbitrary maintenance is facilitated by the presence of the lid, while the liquid that may be present in the chamber. Ensure controlled emissions of.

In other words, the outflow system can connect the outside of the pump to the pump body, pump lid, or any device that passes through the pump body and lid, i.e., at a pre-designed location. Can consist of appliances.

Advantageously, the liquid outflow system comprises at least one hole, the at least one opening and the at least one hole being arranged facing each other, i.e. facing each other.

This arrangement makes it possible to have equipment that is particularly compact and inexpensive in that the distance between the spill system and the spill system is minimized.

Advantageously, the liquid spill system includes a sealing element placed between the spill system and the spill system, which makes it possible to ensure a seal between the pump and the housing of the appliance, and therefore. Avoid the risk of accidental contact between the liquid and the electrical or multiple components of the appliance. In other words, with this arrangement, any liquid that could enter the pump chamber if the deformable hose ruptures is drained in a well-thought-out and controlled manner, especially at the design stage. Accurately defined to be drained directly out of the housing containing the pump. In addition to improving safety, draining the liquid from the device caused the user to malfunction inside his / her hairdressing device (in this case, for example, the deformable hose ruptured). That) will at least be visually warned. Advantageously, the sealing element includes an O-ring.

According to one advantageous embodiment, the peristaltic pump comprises a sealing system designed to contain the liquid in the chamber if the deformable hose ruptures. Therefore, when the deformable hose ruptures, the liquid is contained in the pump chamber, i.e., not out of control, out of the pump, but only through the pump outflow system. As a result, any rupture of the peristaltic pump hose remains contained within the pump and does not leak out of the pump, as would normally be the case with a pump known in the art. Has limited results. The liquid is discharged only by the outflow system, i.e. to a well-defined location, and advantageously according to a controlled trajectory, and the location and, advantageously, the outflow trajectory is carefully prior carefully by the pump designer. It is defined. Further, if there is a closed system, the outflow system is the only possible outlet for any liquid that may be present in the chamber, and the chamber is also sealed. Therefore, regardless of the spatial orientation of the pump, only the outflow system guarantees the discharge of liquid. Therefore, the pump as defined by the present invention should be installed in a space where any presence of liquid should normally be avoided, eg, in the immediate vicinity of electrical or electronic components, as detailed below. Is possible.

According to an advantageous embodiment, the chamber comprises a rotor in contact with a deformable hose, the rotor is connected to a drive shaft passing through the pump body, and a sealing system is located between the drive shaft and the pump body. , Includes a first sealing element. Therefore, even if the deformable hose bursts, the liquid cannot leak from the gap between the drive shaft, which is a rotatable part, and the pump body, which is a fixed part. According to this advantageous embodiment, the first sealing element includes a lip seal, and preferably a double lip seal. This type of seal, especially the double lip seal, is between the rotating shaft, in this case the seal lip or the drive shaft pressed by multiple lips, and the fixed part, in this case the pump body where the seal is held. Ensuring a very good seal.

According to another advantageous embodiment, the peristaltic pump comprises a lid that cooperates with the pump body, and the sealing system comprises a second sealing element disposed between the pump body and the lid. And this structure makes it possible to provide a peristaltic pump, the presence of the lid, which facilitates its assembly and / or maintenance, while between the pump body and the lid if the deformable hose ruptures. Ensuring hermetically sealed. Advantageously, the second sealing element includes a circular cross-section seal that is at least partially located around the pump body and the edge of the lid.

It could also be foreseen that instead of passing through the pump body as described above, the drive shaft would pass through the lid and a first sealing element would be placed between the drive shaft and the lid.

According to another advantageous embodiment, the peristaltic pump has an inlet connector intended to receive a liquid suction duct and an outlet connector intended to receive a liquid discharge duct connected to a deformable hose. To prepare for. The sealing system comprises a third sealing element located between the pump body and at least one of the inlet or outlet connectors. Alternatively, a third sealing element is placed between the lid and at least one of the inlet or outlet connectors. Alternatively, the third sealing element is located between the pump body, the lid, and at least one of the inlet or outlet connectors. Such a structure ensures a seal between the chamber and the outside of the pump at the pump connector, regardless of the spatial orientation of the pump. For example, the pump may be placed with at least one connector located at the bottom, if not both, and even if the deformable hose breaks, the connector, eg, the connector, eg. There will be no liquid leakage between the pump body or the lid.

According to the first modification of the advantageous embodiment described above, the third sealing element advantageously comprises a plate made of silicone, each of the inlet and outlet connectors passing through the plate. The plate is then disposed between the pump body and / or the pump lid and around at least one of the inlet or outlet connectors. Advantageously, the plate contains two openings, preferably two holes, each opening containing one of the connectors. This structure includes a seal with a connector when these parts are attached to the pump (eg, when they are not molded with the pump body or lid, as is often the case with pumps), the chamber. Ensure the sealing of. In addition, this solution allows the connector to be disassembled without damaging the connector or the pump itself. As detailed below, the use of silicone plates is particularly advantageous and inexpensive when the two connectors are close to each other and placed on the same plane forming the surface of the pump.

According to the second modification of the advantageous embodiment described above, the third sealing element is disposed between the pump body and / or optionally the lid and each of the inlet and outlet connectors, and the third. The sealing element comprises two O-rings. In other words, according to this variant, each connector has its own O-ring between the connector and the pump body and / or lid, ensuring that the chamber is sealed in the connector. This solution is particularly advantageous when the connectors are attached to the pump (eg, not molded with the pump body or lid), separated from each other, and / or not in the same plane.

Advantageously, the inlet and outlet connectors belong to the same plane, belonging to the single outside of the peristaltic pump. This allows the connecting elements to have a particularly compact pump assembled on the same side, thus limiting the length of tubes required at the inlet and outlet of the pump. Advantageously, the inlet and outlet connectors each advantageously include a bend having a substantially 90 ° angle. This type of connector facilitates pump installation by placing the pump sideways in the suction and discharge ducts at the inlet and outlet of the pump, respectively. In this way, the size of the pump assembly and liquid tube can be smaller.

Of course, the above embodiments are fully compatible with each other, and other advantageous embodiments may result from various combinations thereof. In particular, a peristaltic pump, which would result from a combination of the above three embodiments, could be foreseen. This is easy to manufacture and maintain, especially small, as it has a cheap and completely watertight lid, regardless of spatial orientation, if the deformable hose ruptures. Will bring a peristaltic pump. The sealing system will then include the first, second, and third sealing elements described above.

The following description of an advantageous and non-limiting embodiment of a hairdressing device emphasizes the features that are the subject of the present invention. This description is based on the figure below.

It is a perspective view of the hairdressing device described by this invention. It is a figure which showed the instrument of FIG. 1 from another angle. It is a perspective view of the 1st branch part of the instrument of FIG. It is a detailed perspective view of the area A of FIG. The same detail A as in FIG. 4 is shown, but a specific part is erased in order to confirm the internal component of the branch portion. FIG. 3 is a perspective view of a peristaltic pump as defined by the present invention. It is an exploded view of the pump component of FIG.

As shown in FIG. 1, the household appliance 1 defined by the present invention is a hair straightener, more specifically a hair straightener with a liquid consumption system 4. More specifically, the liquid consumption system 4 includes, in this case, a vaporization chamber, a vaporization means 41, and a means for diffusing the vapor thus generated towards the hair tress 42. .. The diffusing means 42 can be formed, as shown, in particular by a series of openings or by slots or diffusing grooves. Such elements are well known to those of skill in the art and are detailed, for example, in Patent Document 4 relating to the applicant.

The household appliances 1 are connected to each other by hinges 13 substantially located at the ends of the first branch 11 and the second branch 12, respectively, of the first branch 11 and the second branch 12. The branch portion 12 is included. The bifurcations can therefore be moved relative to each other in a rotational motion, or more precisely a clamping motion.

As seen in FIG. 3, the first branch 11 comprises a first surface 112 for treating the hair by contact, in this case a heating plate. The second bifurcation 12 comprises a second surface 122 for treating the hair by contact, as seen in FIG. 2, which is complementary to the first treated surface 112. Preferably, the second surface 122 for contact treatment is also heated.

In such a well-known method, the hinge 13 allows the user to open and then shape the hair straightening iron to place a bundle of hair between the treated surfaces 112, 122. Allows the iron to be closed on a bundle of hair, generally for straightening.

As seen in FIG. 2, household appliances 1 also include a liquid storage system, in this case a reservoir 3. Preferably, the reservoir is intended to store water. However, without departing from the scope of the invention, it could be assumed that the reservoir could store cosmetics, optionally diluted with water.

According to the illustrated invention, the reservoir is incorporated into the first branch portion 11. However, it is perfectly possible for the reservoir to be separated from the first branch 11 and the second branch 12 without departing from the scope of the invention. In fact, the reservoir may be located away from the first branch 11 and the second branch 12, and may be connected to one of the branches by, for example, a hose capable of carrying the liquid (ie, iron). Can be on a remote base (located away from). Such an arrangement is described, for example, in Patent Document 5 relating to the applicant.

As seen in FIGS. 3 and 4, the household appliance 1 includes a housing 111 formed by the first branch portion 11. However, although this is not shown, it is entirely possible for the housing to be formed by the remote base described above without departing from the scope of the invention.

Accordingly, the housing 111 comprises an outer shell made of, for example, a plastic material, including at least one electrical or electronic component such as a heating element (eg, PTC), an electric motor 5, a temperature sensor, a capacitor, an electronic card, and the like. To form. These elements are usually very sensitive to any contact with liquids, especially water, such contact can result in their damage, even their destruction, and even the risk of electrocution. Can connect.

As seen in FIG. 4, the housing 111 is from the liquid transport system 32, 6, 33, in this case from the perturbation pump or hose 32, 33, and / or from the liquid storage system, in this case reservoir 3. Includes a liquid drainage system 114 designed to drain liquid from the housing 111 in the event of a liquid leak. The liquid discharge system 114 is arranged so that the liquid does not come into contact with electrical or electronic components. More specifically, the liquid discharge system 114 includes two openings 1141 arranged adjacent to each other. Each of the openings 1141 passes through the housing 111 to connect the inside of the housing 111 to the outside. The use of two separate openings ensures sufficient drainage flow and ensures minimal flow if one of the openings 1141 is clogged. As shown in FIG. 4, each opening 1141 is a hole having a diameter substantially equal to 1.2 mm. Therefore, the possible discharge section is about 2.26 mm ² . The holes are separated by about 2.5 mm.

The liquid discharge system 114 is located at a distance of approximately 25 mm from the end of the first treated surface 112, which ensures a safe distance for water to flow through the discharge system 114 and allows the discharged liquid to flow. Prevents contact with the first treated surface 112. The liquid drainage system 114 is located opposite the second branch portion 12, which allows the second branch portion 12 to cover the liquid drainage system 114 when the straightener is closed. And therefore improve the overall aesthetics.

To supply the liquid, preferably water, to the liquid consumption system 4, the household appliance 1 includes a liquid transport system, in this case a peristaltic pump 6. According to the illustrated invention, the peristaltic pump 6 is incorporated into the first branch, as seen in FIG. 5, but without departing from the scope of the invention, the peristaltic pump 6 is incorporated into the remote base described above. It is also possible.

As seen in FIGS. 5 and 6, the peristaltic pump 6 specifically includes a pump body 60. An inlet connector 61 is arranged in the pump body 60 to connect the peristaltic pump 6 to the suction duct 32, which itself is connected to the reservoir 3. An outlet connector 62 is arranged in the pump body 60 to connect the peristaltic pump to the liquid consumption system 4 by the drain duct 33. More specifically, each of the inlet connector 61 and the outlet connector 62 passes through the pump body 60. Therefore, a portion of the inlet connector 61 and the outlet connector 62 protrudes outside the pump, and a portion of the inlet connector 61 and the outlet connector 62 protrudes into the pump, that is, into the chamber 68. As seen in FIG. 5, the portions of the inlet connector 61 and the outlet connector 62 projecting outward of the pump are then connected to the suction duct 32 and the discharge duct 33, respectively. The portions of the inlet connector 61 and the outlet connector 62 projecting into the chamber 68 are then connected to the deformable hose 63.

Advantageously, as seen in FIGS. 6 and 7, the inlet connector 61 and the exit connector 62 each advantageously include a bend having an angle of 90 °. Preferably, the bend is on the outside of the peristaltic pump 6 and is in contact with the pump body 60. Advantageously, the bend is rigid, as is the connector, which ensures good strength and avoids the phenomenon of inadvertent bending. Therefore, the inlet connector 61 and the outlet connector 62 may be located on the same side of the pump body 60, even if the size on that side is limited. In fact, the inlet connector 61 and the outlet connector 62 can be arranged adjacent to each other, or even come into contact with each other, as shown, thereby limiting the size of the peristaltic pump 6 and with the suction pipe 32. It makes it possible to simplify the route of the discharge pipe 33. In fact, the inlet connector 61 and the outlet connector 62 can be bent in opposite directions while adjacent to each other due to their 90 ° bend, which is especially simple, small, out-of-pump fluid circuit. Allows you to have. In fact, the suction duct 32 and the discharge duct 33 are substantially aligned with each other, i.e., in the same plane and along substantially the same line. Further, each of these ducts enters and exits the peristaltic pump 6 through the same pump surface, i.e., only on one side. Therefore, it is possible to place the peristaltic pump 6 in a particularly small, difficult-to-access location, as it is sufficient that only one side of the pump is accessible to connect the suction pipe 32 and the discharge pipe 33. Is.

As shown in FIG. 6, the pump also includes a lid 64 that works with the pump body 60. More specifically, the lid 64 is attached to the pump body 60, which makes it possible to have a pump that is easy to assemble. In particular, it facilitates the assembly of various internal components, such as the components of the rotor 65. In addition, the peristaltic pump 6 can be disassembled and reassembled at any time as needed without deterioration, for example to repair internal components. The peristaltic pump 6 is also connected to an electric motor 5 intended to move various moving parts of the peristaltic pump 6 and thus move the liquid from the reservoir 3 to the liquid consumption system 4.

FIG. 7 shows various components of the peristaltic pump 6. Accordingly, the pump body 60 forms a chamber 68, i.e., a space, recess, or housing in which various elements are found. In this case, the chamber 68 is defined by the pump body 60 and closed by the lid 64. Thus, the chamber includes a deformable hose 63, a rotor 65 including one or more pressure elements 651 connected to the rotor by a mount 653, and one or more springs 652. The deformable hose 63 is fixed and connected to the inlet connector 61 on the one hand and the outlet connector 62 on the other to form a loop. The rotor 65 is located in the center of the loop, passes through the pump body 60, and is rotated by a drive shaft 51 connected to the motor shaft of the electric motor 5. The rotor is guided in rotation by a bearing 645 housed in a lid. As the drive shaft rotates, the pressure element 651, eg the rollers, periodically crushes the deformable hose 63, and under the influence of their displacement following the rotation of the rotor 65, this also causes a suction phenomenon. Causes drainage of liquid in the deformable hose 63. Therefore, the liquid is sucked in on one side of the pump and discharged on the other side. This operation is very classic and is a feature of peristaltic pumps known to those of skill in the art and will not be described in further detail here. Both the peristaltic pump 6 and the electric motor are connected to the mounting plate 52, for example, by a screw 53.

As seen in FIG. 7, the peristaltic pump 6 includes sealing systems 661, 662, 663. The latter constitutes a safety device that is an integral part of the pump described in detail below.

More specifically, the sealing system in the peristaltic pump 6 includes a first sealing element 661 disposed between the drive shaft 51 and the pump body 60 (or, as an alternative, the lid 64). More specifically, the first sealing element 661 is a lip seal, preferably a double lip seal. Such a seal actually provides complete watertightness between the rotating part (in this case the drive shaft 51) and the fixed part (in this case the pump body 60 (or optionally the lid 64)). Very effective in securing. Thus, thanks to the presence of this first sealing element 661, it may be present inside the chamber 68, for example, in the event of a rupture of the deformable hose 63 (or accidental separation of the inlet and / or outlet connectors). The sexual liquid may leak from the chamber, i.e. to the outside of the peristaltic pump 6, through a gap, i.e., the functional clearance between the drive shaft 51 (rotating part) and the pump body 60 (fixed part). There will not be. The first sealing element 661 guarantees both effective rotation of the drive shaft 51 with respect to the pump body 60 (or possibly the lid), while ensuring the sealing between these two parts.

According to the illustrated embodiment, the peristaltic pump 6 also includes a second sealing element 662 located between the pump body 60 and the lid 64, as seen in FIG. The second sealing element 662 is advantageously formed by a circular cross-section seal. The second sealing element 662 is then located around the chamber 68, near the rim, i.e., near the pump body 60 and the edge of the lid. As can be seen in FIG. 7, the second sealing element 662 follows the contours of the pump body 60 and the lid 64 and thus exhibits its shape. The second sealing element 662 forms a nearly loop by itself, except that this element has two ends, i.e., not a closed ring. Thus, when installed between the pump body and the lid, the second sealing element 662 takes the form of a horseshoe, or, in fact, the Greek capital letter Omega. Therefore, the presence of this second sealing element 662 makes it possible to ensure the sealing between the pump body 60 and the lid 64, while allowing the lid 64 to be disassembled and reassembled. However, it can be seen that this second sealing element 662 does not fit perfectly around the pump body 60. In other words, the second sealing element is located at least 60%, preferably 80% of the rim of the chamber 68, rather than around the entire rim of the chamber 68. The rest of the rim is then sealed by a third sealing element 663, which is a complete seal between the pump body 60 and the lid 64, and thus the chamber. It makes it possible to ensure the watertightness of 68.

As can be seen in FIG. 7, the peristaltic pump also includes a third sealing element 663. The latter includes a plate through which the inlet connector 61 and the outlet connector 62 pass. Preferably, the plate is made from silicone, or any other material that can ensure sealing. The plate then includes two openings that allow the inlet connector 61 and the exit connector 62 to pass through it. The plate is made of a material that is flexible enough to ensure sealing around the inlet connector 61 and the outlet connector 62. Therefore, the plate comes into contact with the inlet connector 61 and the outlet connector 62, the pump body 60, and the lid 64, as can be seen in FIG. This plate, in combination with the second sealing element 662 described above, in a meaningful way by closing the edge of the chamber, completes the watertightness of the chamber 68, ie between the lid 64 and the pump body 60. Allows for complete sealing.

Therefore, the chamber 68 is completely watertight due to the combined presence of the above sealing elements, i.e., the first sealing element 661, the second sealing element 662, and the third sealing element 663. As a result, if the liquid accidentally escapes from the deformable hose 63 (rupture or separation of the deformable hose 63) and enters chamber 68, the liquid (usually water) cannot escape into chamber 68. Will be trapped. This gives a peristaltic pump, which is particularly safe because it is completely watertight, that is, it does not allow the liquid to dissipate even if its deformable hose ruptures. Make it possible. It is then possible to use the peristaltic pumps of the invention in the immediate vicinity of certain locations where the presence of liquids is prohibited, such as electrical or electronic components.

However, the illustrated invention includes another safety device, which may further constitute the invention by itself. In fact, the pumps shown in FIGS. 6 and 7 are such that in the event of a rupture of the deformable hose 63 in the peristaltic pump 6, liquid is drained from the chamber 68 to the outside of the peristaltic pump 6 according to a controlled trajectory. Includes a spill system 67 designed for. This safety device is particularly effective when used in household appliances 1 including a liquid drainage system 114, as detailed below.

As can be seen in FIGS. 5-7, the peristaltic pump 6 comprises two holes 671, which connect the chamber 68 to the outside of the pump at a particular location carefully selected by the designer. The spill system 67 is formed. Each hole has a diameter of about 1.2 mm, which corresponds to a 2.26 mm ² discharge section. The holes are 2.5 mm apart. Therefore, if a liquid accidentally enters chamber 68 (due to the above causes), it is possible to control the flow trajectory of the liquid to a particular location previously considered and selected by the designer. For example, at that time, the location of the outflow system can keep the flow of liquid away from electrical or electronic components.

By combining the spill system 67 with the sealing elements 661, 662, 663 as defined above, the spill system 67 alone controlled the chamber 68 after the rupture of the deformable hose 63. Outflow is guaranteed regardless of the spatial orientation of the pump. In fact, if the pump is oriented according to FIG. 6, the liquid will then flow naturally by gravity through the outflow system 67, located at a lower point in the pump body. In this case, the first sealing element 661 and the third sealing element 663 are not required for proper flow by the spill system alone, as these elements are located above the spill system 67. On the other hand, if the pumps are oriented differently, for example if the bottom is provided with an inlet connector 61 and an outlet connector 62, the outflow system 67 is then located at a high point on the pump. In the absence of the third sealing element 663, the liquid could then leak through the gap between the pump body 60 and the inlet connector 61 and the outlet connector 62. In the absence of the second sealing element 662, the liquid could also escape through the gap between the drive shaft 51 and the pump body 60, even before it reaches the outflow system 67. In that case, liquid leakage will not be controlled as in the case of conventional pumps when the deformable hose breaks. The above-mentioned sealing elements 661, 662, 663 do not allow water to leak through these gaps and are therefore forced to flow through the spill system 67 and only through the spill system 67. To. In addition, the presence of sealing elements 661, 662, 663 is the flow of unwanted liquid, i.e., spillage, if the spill system is clogged or the flow rate is not sufficient to empty the chamber fast enough. Allows you to avoid other places than passing through the system.

According to an exemplary embodiment of the invention, the outflow system 67 in the peristaltic pump 6 communicates with the discharge system 114 in the housing 111. In this case, the spill system 67 is arranged facing the spill system 114, as can be seen in FIGS. 4 and 5. In other words, the spill system 67 is located facing the spill system 114. More specifically, the spill system 67 comprises two holes 671, the spill system 114 also comprises two openings 1141 and belongs to the spill system 67, each hole 671 being an opening in the spill system 114. They are arranged facing, i.e. facing, one of the portions 1141.

Advantageously and significantly, the spill section of the spill system 67 and the spill section of the spill system 114 are substantially identical and are about 2.26 mm ² in size, which is in chamber 68 without the funnel phenomenon. Guarantees a complete spill of any liquid that may be present in.

Thus, the spill system 67 and the spill system 114 are separated by a sealing element 664, in this case an O-ring, that ensures a seal between the spill system and the spill system 114. The sealing element 664 is held in a slot around the outflow system 67 and thus contacts the housing 111 and the peristaltic pump 6, in particular the pump body 60. According to this embodiment of the present invention, if the deformable hose 63 in the peristaltic pump 6 of the household appliance 1 ruptures, the liquid is then discharged in a controlled manner as defined by the design, in other words. Discharged by the system 114 alone and through the outflow system 67 of the peristaltic pump 6 in a well thought out manner, the liquid cannot contact the electrical or electronic components inside the housing 111. In other words, the interior of the housing 111 is protected from any liquid, even in the event of a peristaltic pump 6 failure, which may be the household appliances themselves (its electrical or electronic components), but the user (electric shock). (Risk of death), but it greatly improves the safety of household appliances 1.
