Description

  The present invention relates to a hot water apparatus including a water tank and means for heating water.

  The present invention is aimed at heating household water.

  Hot water devices have traditionally been cylindrical and therefore take up considerable space.

  However, there is a water heater having a flat shape as described in document US Pat. No. 4,551,612. The water heater described therein is flat and has a parallelepiped shape. In order to withstand the pressure of the water entering the device, the inner wall has been jagged. This device comprises several resistors placed at various heights perpendicular to these blunt saw blades.

  With this device, the knurled walls cannot be separated too much to withstand pressure, so only a small amount of water can be heated.

  Document British Patent No. 731769 describes a flat water heater having a plurality of vertical compartments, one compartment containing a resistor and the other compartment containing means for collecting hot water. Due to its structure, this device has a thermal imbalance and each compartment is not heated at the same temperature because of limited water movement.

Document German Patent No. 4012203 describes a water heater with a resistor and a plurality of cylindrical sections in the lower part. This water heater has many drawbacks such as large heat loss between compartments due to the shape of the compartments. Furthermore, this shape reduces the volume of water that can be stored in the water heater. Finally, the water heater must be connected to hot and cold water at the top. If the pipes are misplaced, piping work is required.

  The present invention is a hot water apparatus comprising a water tank and heating means, the tank having a series of individual juxtaposed conduits, the primary ends of these conduits exiting the common water collection section. , These secondary ends are exiting a common water heating section, and the conduit has a rectangular cross section, the common water heating section being capable of accepting heating means positioned perpendicular to the conduit It is intended to solve all or part of the above problems by proposing a hot water device.

  An advantage of the present invention is that large volumes of water can be retained and heated while in the form of a flat parallelepiped.

  In fact, the internal structure consists of individual juxtaposed conduits ending with a common hot water collector that enhances the device's ability to withstand water pressure, enhances water movement, and thus enhances the convection that occurs within the device.

  In certain embodiments, the separate juxtaposed conduits have their secondary ends exiting a common water heater.

  Another advantage of the device according to the invention is the rectangular cross section of the conduit. Thus, rectangular cross-section conduits are juxtaposed, which greatly reduces heat loss between the conduits. Moreover, the rectangular cross section of the conduit is optimal for the device to contain a large volume of water in a given space.

  The perpendicular position of the heating means relative to the conduit will improve the convection of the water inside the water heater, thus improving the efficiency of the water heater.

  Moreover, the outer wall of the at least one common part advantageously overlaps with the outer wall around the conduit. This structure helps improve the ability of the device to withstand water pressure.

  The two common parts may comprise at least one pluggable orifice for receiving the heating means.

  Another advantage of the present invention is the ability to use the device at various locations to suit the external conditions encountered. The device can be rotated 180 ° or 90 °.

  Other goals and advantages will become apparent in the following description of the preferred but non-limiting embodiments.

  First, the present invention provides a water tank and heating means characterized in that the water tank comprises a plurality of individual adjacent conduits, and the primary ends of the conduits terminate in a common part for collecting hot water. It should be remembered that it is a hot water device containing.

According to a preferred alternative embodiment of the invention, the hot water device is

  The accompanying drawings are given by way of illustration and are not limiting. These drawings depict only one embodiment of the present invention that makes it easier to understand the present invention.

  The hot water apparatus 1 is composed of individual lined conduits 5 whose primary ends terminate at a common portion 2 and whose secondary ends terminate at a complementary common portion 3.

  Advantageously, the common part 2 includes the opening of the hot water discharge pipe for collecting hot water, and the common complementary part 3 includes the heating means 4 and is therefore a common water heating part.

  It is advantageous for the conduit 5 to be formed from a tube of rectangular cross section joined side by side.

  In another embodiment, the conduit is made of a series of rectangular cross-section tubes separated from each other with an inter-section space.

  According to yet another embodiment, the conduit 5 is formed by positioning a septum 10 that extends at regular intervals, preferably across the two walls 11.

  The two walls 11 constitute the outer core of the hot water device 1.

  According to a certain configuration, the partition wall 11 has a protruding tenon 13 along its outer periphery. It is advantageous that only two opposite sides cooperating with the wall 11 are provided with a protruding tenon 13.

  The protruding tenon 13 is designed to cooperate with a receiving slot 12 aligned on the wall 11.

  When the protruding tenon 13 is inserted into the receiving slot 12, a weld 14 is performed along the surface of the receiving slot 12.

  The advantage of this conduit 5 embodiment is the speed and cost of assembly because the weld 14 is not performed over the entire length of the septum 10 but only in the tenon 13 and slot 12.

  It is advantageous for the common part 2 and the complementary common part 3 to be approximately symmetrical and of identical dimensions, both including at least one pluggable orifice (not shown) for receiving the heating means 4.

  The heating means 4 is preferably oriented in a direction perpendicular to the arrangement direction of the conduits 5.

  In order to enhance the resistance of the device 1 to water pressure, at least one outer wall of the common part 2 or 3 overlaps with the outer wall surrounding the conduit 5.

  In a preferred embodiment, the device 1 is surrounded by a heat insulating material to reduce heat loss from the device 1.

  The device 1 has a short tube 6 which is advantageously a cold water feed tube according to FIG. 5 and a long tube 7 which is advantageously a hot water discharge tube according to FIG. 5 and slightly shorter than the length of the device 1. .

  The device 1 is advantageously provided with a drainage means 8. In a preferred embodiment, the device 1 comprises means 9 for fixing to the wall.

  In a preferred embodiment, all tubes 6, 7, and 8 are located on the same side of the device.

Example of operation of the device according to FIG. 5 Cold water is fed to the device 1 in the complementary common part 3 through a short tube 6. Water is heated by the heating means 4 located in the complementary common part 3 for water heating. The hotter the water, the more it rises through the conduit 5 towards the common part 2 for collecting hot water. Hot water is collected by the long pipe 7, and the opening of the pipe 7 is located in the common part 2 for collecting hot water.

Example of operation of the device 1 according to FIG. 6 If a water tube is entered through the top of the device 1, the device can be used in this orientation. The cold water reaches the device 1 in the common part 2 through the long pipe 7. Water is heated by the heating means 4 located in the common part 2 for water heating. The hotter the water, the more it rises through the conduit 5 towards the complementary common part 3 that is used to collect the hot water. Hot water is collected by a short tube 6 and the opening of the tube 6 is located in the common part 2 for collecting hot water.

  According to another operating method (not shown), the device 1 can be placed horizontally. Surprisingly, it has been observed that the horizontal arrangement of the conduits prevents deterioration of the water circulation in the device so that convection is maintained quite effectively.
