Abstract
The present invention relates to a modular water heating device, comprising a means to allow a quantity of hot water to be made available in a short time and/or to avoid any risk of hot water shortage, in order to ensure the maximum comfort of the consumer.
Description
- A subject of the present invention is a modular water heating device, comprising a means to allow a quantity of hot water to be made available in a short time and/or to avoid any risk of hot water shortage in order to ensure the maximum comfort of the consumer,
- The invention relates in particular to providing sanitary hot water for domestic use.
- Water heating devices for domestic use conventionally consist of a single cylindrical or spherical tank that is bulky and difficult to incorporate into modern homes. These devices involve heating the entire volume of water contained in the tank, regardless of the draw-off quantity needed.
- The more advanced models have temperature recovery times (to increase from 18° C. to 65° C.) comprised between 5 and 6 hours. There are many drawbacks to these devices:
-
- a long wait by the user for a satisfactory volume of hot water to be obtained,
- absence of information on the quantity of hot water consumed and on the quantity still available,
- inability to take any action except in reaction to a sudden hot water shortage.
- When lack of hot water occurs, the user can at best switch the device to manual override and wait the required few hours in order to have a sufficient quantity of hot water available.
- Moreover, European
patent application EP 2 418 331 describes a modular device for heating sanitary water, capable of being built in, comprising a self-supporting frame, independent water tanks and heating means that are outside the tanks. By its modular design, this device overcomes the drawback of needing to heat the total mass of water at all times. However, this device has the same drawbacks as those described above for conventional water heaters as regards the ability to have a quantity of hot water available in a short time and/or to avoid any risk of hot water shortage in order to ensure the maximum comfort of the consumer. - The present invention aims to overcome these drawbacks.
- Thus a subject of the invention is a water heating device, advantageously for heating sanitary water, capable of comprising at least two tanks having sizes and shapes that are identical or different, connected together by water transportation means, capable of comprising a cold water inlet on at least one of said tanks and a hot water outlet on at least one other of said tanks, it being understood that between its entry into the device and its exit from said device it is possible for circulation of the water to have taken place within the set of said tanks forming said device, each of said tanks being capable of being equipped with a water heating means that is independent for each tank and individually equipped with a temperature sensor for the water contained in the tank, linked to a system for regulating said water heating means, the tank that is the furthest downstream in the direction of flow of the water being capable of comprising moreover at least one second water heating means, independent of the first water heating means of said tank, said second water heating means being moreover capable of being equipped with a temperature sensor linked to a system for regulating said second water heating means.
- A first advantage of the invention is its geometry. The latter can allow easy incorporation into a space having small dimensions such as for example a double wall.
- Another advantage of the invention is its modular design. The fact that each tank is capable of being independent in terms of heating makes it possible for only one or more tanks to be heated to and regulated at the chosen temperature, thus optimizing the available volume of hot water. It is therefore easy to adapt the usable volume of water for example to the number of persons likely to use the hot water. The advantage is to adapt the consumption of electricity more closely to the needs of the users and thus result in significant energy saving.
- According to the invention, said water heating means can be any means known in the field such as for example a system of immersion heating elements or a heating panel system applied directly onto at least one outer wall of the tank. Preferably according to the invention, said heating means can be a heating panel system applied directly onto at least one outer wall of the tank and even more advantageously a large surface-area heating panel system applied directly onto at least one outer wall of the tank. Very advantageously said heating panel system can cover the walls of the tank in their entirety.
- It is known that heating means situated inside the tank, although effective, have some drawbacks such as accelerating corrosion phenomena and the appearance of hot spots promoting the formation of limescale and limiting the lifespan of the immersion heating means.
- The external heating panel solution moreover makes it possible, for equivalent power, to increase the exchange surface area between the heating element and the water, reducing the applied power in watts per cm2, to totally eliminate hot spots and thus significantly reduce natural limescale formation. This solution moreover has the advantage of better maintaining the performance over time of the heating element and considerably increasing its lifespan.
- According to the invention, it is possible for said water heating means to have a power rating comprised between 100 and 1200 watts, preferably between 200 and 400 watts.
- According to the invention, said water heating device can comprise as many tanks as desired above 2, the number of course depending on the volume of each tank and the total volume of hot water that is potentially required. A person skilled in the art will of course have no difficulty in adapting this fact. Advantageously, it is possible for the device according to the invention to comprise between 2 and 6 tanks, even more advantageously 4.
- According to the invention, said tanks can adopt any shapes required, independently or simultaneously. It is easily understood that the final shape of each tank will depend on the use for which it is intended as well as the environment in which it is to be used. Thus according to the invention, the tanks can for example adopt a cylindrical shape or a hexahedral shape with pairs of parallel faces such as cubes, rectangular parallelepipeds or rhombohedrons, or even a spherical shape. Advantageously according to the invention, it is possible for said tanks to be cylindrical in shape.
- According to the invention, said tanks can adopt any sizes desired, independently or simultaneously. It is easily understood that the final size of each tank will depend on the use for which it is intended as well as the environment in which it is to be used. Advantageously according to the invention, the tanks can have dimensions compatible with their siting in a space encompassed by the void volume of a double wall, such as for example in the space encompassed by the self-supporting frame that serves to support the elements of a standard wall hung toilet assembly.
- According to the invention, said system(s) for regulating said one or more water heating means can be of any known type, for example mechanical or electronic, advantageously electronic.

- These two variants must allow rapid heating of the volume of water contained in the tank, at the very least in significantly less time than if the first water heating means of said tank were used alone.
- According to a variant of the invention, the heating panels can moreover be completely or partially covered with a layer of thermal insulation.
- Thus according to the invention, said second water heating means can have a power rating comprised between 200 and 2400 watts, preferably, between 400 and 1600 watts.
- Said second water heating means can moreover be equipped with a temperature sensor linked to a system for regulating said second water heating means. As for the first heating means, said system for regulating said second water heating means can be of any known type, for example mechanical or electronic, advantageously electronic.
- Similarly according to the invention, it is possible for said system for regulating said second water heating means to be controlled directly or remotely, advantageously remotely. When controlled remotely, said regulation system can be linked to the control means by any known transmission system, such as for example a wired system, a remote wireless transmission system such as for example electromagnetic radio waves, for example according to the Wi-Fi®, Wi-Max®, Bluetooth®, ZigBee®, Hiperlan® or even DECT® protocols.
- It is possible for said second water heating means to be started on demand only and for a reduced number of heating cycles, advantageously a single heating cycle.
- It can be started at any time using said control means to which it is linked, as decided by the consumer who wishes to obtain hot water rapidly, for example when the device is re-started, for example after it has been shut off for an extended period, or when an unexpected need arises for a greater quantity of hot water than foreseen.
- According to the invention, said device can moreover comprise means for automatically regulating its operation, such as for example a means making it possible to finally switch off the second water heating means when the volume of hot water contained in the tank in question has reached the desired temperature and to return said device automatically to its normal programming so as to avoid structural overconsumption for a merely occasional requirement.
- According to the invention, said device can moreover comprise an embedded water consumption analysis function which, using an electronic water meter positioned on the hot water outlet, can allow measurement in real time of the quantity of hot water consumed. Thus measuring the ratio between hot water consumed and hot water available in the device can allow continuous measurement of the current availability level and therefore the risk of shortage. When a pre-set warning threshold is exceeded, said second water heating means can be activated automatically or directly by the user after being informed by the device of the hot water reserve supply status.
- According to the invention, the device can moreover comprise any means necessary to install said device in its intended place, such as for example mounting brackets, means of support from below or even a self-supporting frame to which the different elements of said device will be fixed.
