Description

The technical solution relates to meeting the vital needs of a person, namely to devices for taking hot baths, in particular to portable bath tubs and fonts that can be used, for example, outdoors in recreation areas for the purpose of conducting water, relaxation and / or hygienic procedures.

From the prior art, a device for taking hot baths is known, including a metal container containing walls and a bottom, while the walls include at least three horizontal rows located at an angle to each other, each of the rows is made with flat trapezoidal faces mated to each other lateral sides, and the smaller base of the trapezoidal face of one row is mated with the large base of the trapezoidal face of the underlying row, while the pairing of the faces is made with the formation of ribs, and the bottom is made flat in the form of an equilateral polygon, while the sides of the polygon are conjugated with the lower bases of the trapezoidal faces of the lower row ( RF patent No. RU 185118, IPC A61H 33/00, published on November 22, 2018).

From the prior art, a device for taking hot baths is known, including a metal container containing walls and a bottom, an oven made in the form on the basis of a three-dimensional polyhedral figure, located on the outside of the container, in its lower part and rigidly connected to the walls of the container, the container walls of which include at least three horizontal rows located at an angle to each other, each of the rows is made with flat trapezoidal faces mated to each other by the sides, and the smaller base of the trapezoidal face of one row is mated with the large base of the trapezoidal face of the underlying row, while the faces are mated made with the formation of ribs, the number of side faces of the furnace is equal to the number of faces of the lower row of the container, and the bottom is made flat in the form of an equilateral polygon, the sides of which are conjugated with the lower bases of the trapezoidal faces of the lower row (RF Patent No. RU 185338, IPC A61H 33/00; E04H 4 /00, published 11/30/2018).

The technical result of the proposed technical solution is manifested in the improvement of manufacturability.

This technical result is achieved by simplifying the process of production, operation and maintenance of the device, increasing its maintainability. In particular, thanks to the possibility of quick and intuitive assembly/dismantling for users at the place of hygiene procedures; the possibility of replacing one of the elements, whether it be a furnace or a container, in case of failure of this element.

The claimed technical result is achieved due to the fact that the device for taking hot baths includes a metal container for liquid, made expanding upwards, containing walls and a bottom, and a furnace with a metal case located under the bottom of the container, while a pipe is connected to the lower part of the container, communicating with a cavity inside the metal container, and on the outer side of the lower part of the metal container there is a protrusion made with the possibility of connection with the upper part of the metal body of the furnace, while the metal body of the furnace is detachably connected by its upper part to the protrusion and is additionally fixed to it by means of fasteners, and a cutout for the pipe is made in the metal body of the furnace.

In order to understand the proposed technical solution, the conjugation of faces should be understood as an inextricable connection of the faces to each other with the formation of a rib at their junction, made by any method, in particular, by welding or by bending from a single part.

The hot bath device includes a metal container for liquid. The container made of the claimed material, with sufficient rigidity, has a low weight, which provides ease of manufacture, transportation and direct use of the device. The metal also provides an increase in the maintainability of the structure, since it allows eliminating defects that may occur during operation (for example, cracks) by welding. In addition, deformed metal sheets in most cases can be straightened without significant deterioration in the performance of the device and do not require replacement. Thus, the use of metal in the design of the device for taking hot baths increases its manufacturability.

The metal also has optimal thermal properties for use in the construction of ovens and other heaters, as it has a high thermal conductivity and promotes rapid and uniform heating of the hot tub container. Other materials that are not strong enough or not elastic enough, but at the same time have similar thermophysical characteristics to metals, do not allow the device to realize its intended purpose, since their use leads to accelerated wear of the structure, a decrease in the safety of its operation and service life.

The container is made of metal, which has high mechanical properties, such as strength, hardness, ensure the reliability of the product.

A furnace with a metal case, installed under the bottom of the tank, improves the manufacturability of the device for taking hot baths due to the convenience of its operation. The stove allows you to heat the water in the tank as quickly as possible, while the heating process does not require constant monitoring and the involvement of people who are not involved in taking water procedures, unlike, for example, keeping an open fire burning, does not depend on weather conditions. In addition, due to the presence of an oven in the lower part of the container, it is easy to install the device for taking hot baths in a supporting structure, for example, in a stand or tripod, since in this case the container does not need to be centered relative to the support, it is convenient to hold it during installation and fastening to support. Making the oven from metal ensures the maintainability of the device for taking hot baths, as it allows to eliminate any defects by replacing damaged parts and fastening new ones by welding or fasteners, and also characterizes the device with a low weight, which simplifies the assembly and transportation of the device for taking hot baths.

To ensure optimal convective heat transfer, it is advisable to place a heat source (furnace) from below, so that the heating lower layers of the liquid can rise up, mixing with the upper layers and transferring heat to them, ensuring uniform heating of the water in the tank. The convective currents of the liquid help to quickly and evenly heat the water in the bathing tank in order to create a comfortable thermal environment. The possibility of rapid uniform heating makes the use of the device more convenient, since the time spent on bringing the device to working condition is reduced.

On the outer side of the lower part of the metal container there is a protrusion made with the possibility of connection with the upper part of the metal body of the furnace. This protrusion allows convenient, rigid and secure integration of the hot tub container with the oven. Such fastening is technologically advanced, since the protrusion in the lower part of the container during the production of the device does not require highly skilled personnel and complex assembly and molding operations. In addition, the connection of the upper part of the furnace body and the vessel through the protrusion is simple and intuitive during operation of the device and also does not require complex assembly operations. This connection is reliable and has a long service life. In addition, the presence of such a connection makes it possible to replace one of the elements (be it an oven, a container for taking hot baths or another metal element), in the event of a failure of this element, which determines the high maintainability of the claimed device. The presence of the protrusion makes it possible to eliminate the need for a welding connection when attaching the furnace to the container, since, due to the presence of a contact surface on the protrusion, it provides conditions for their fastening by means of any detachable fasteners that can be easily replaced with similar ones in case of wear during operation. In addition, the absence of the need for a welding joint allows the use of different metals as the material for the manufacture of the vessel and the furnace body, for example, stainless steel AISI 304 and AISI 430, respectively. This solution also determines the high maintainability of the device, since the container and the furnace are subject to various types of destructive influences.

Also, due to the use of this connection, the probability of detaching the furnace from the vessel and / or capsizing of the vessel is minimized; reliable contact between the metal container and the furnace is ensured over the entire contact area, which has a positive effect on the heating rate of the container and the water in it, as well as the uniformity of heating. The increase in the reliability of the connection is further increased when using fasteners.

A cutout for a pipe is made in the body of the metal furnace, thanks to which it is possible to conveniently and easily connect the body of the metal furnace with the container, as well as to improve the alignment of the dimensions of the connected elements in the form of a metal furnace and a pipe. Making a cut in the furnace body, in turn, does not require complex assembly operations and the involvement of qualified personnel in the manufacture of the furnace, which also improves the manufacturability of the device. This design allows transporting and storing the furnace bodies of the hot bath device separately from the pipe, which characterizes the device with high manufacturability, allows using a relatively small space for these purposes. The cutout in the upper part of the furnace body also provides convenient access to the bottom of the device tank for its cleaning and maintenance, and cleaning and maintenance in this case do not require dismantling the tank.

In particular cases of implementation of the device, the protrusion can be made in the form of a plate, the shape of which corresponds to the shape and size of the cross section of the upper part of the furnace body. The execution of the protrusion in the form of a plate, the shape of which corresponds to the shape and size of the cross section of the upper part of the body, provides the ability to use for connecting the container with the body of simple fasteners of the same type, such as elements of a riveted or bolted connection. The ease of manufacturing the protrusion in the claimed form is due, in particular, to the possibility of at least partial use of the tooling used in the manufacture of the furnace body. In addition, this design of the protrusion allows you to fix the furnace around the entire perimeter of its upper part. Such fastening will exclude the occurrence of distortions and irreversible deformations in the device design during its long-term operation, and will allow replacing failed fastening units, which also further increases the maintainability of the device.

The protrusion can be made with the possibility of location and fixation in the internal volume of the upper part of the furnace body. This design allows you to connect the furnace body with the container as simply and quickly as possible, literally, by putting the furnace body on the container. This is easy to organize in any production area, without the use of lifting equipment. At the same time, due to the fact that the protrusion, after connecting the furnace body to the tank, will be in the internal space, the fixing units will be less susceptible to the influence of the external environment, for example, precipitation on them, the impact of which can lead to irreversible deformation of the units, and, as consequently reducing the maintainability of the device.

Preferably, the pipe cutout extends from the top of the furnace body, preferably to the level of the furnace body corresponding to the lower level of the pipe. This design further simplifies the process of mounting the furnace body and connection with the pipe, since it does not require accurate centering of the pipe relative to the cutout. This design allows you to fix the body with the container after the installation of the pipe, which, under certain conditions, may be more convenient when assembling the device structure. When using a cutout of this shape, the pipe can be easily removed and replaced with another one. In addition, the presence of a cutout that includes free space allows easy and convenient access to the interior of the furnace body and to the pipe without dismantling the entire structure.

The metal container may include an additional metal sheet attached to the metal body of the furnace to cover the free space of the pipe cutout. The additional metal sheet performs several functions. First of all, it increases the tightness of the internal volume of the furnace, limiting the exit of heated air from the hole, which has a positive effect on the heating efficiency of the furnace. Also, the presence of a metal sheet contributes to a more uniform distribution of heat flows emanating from the furnace, due to its own thermal conductivity of the additional sheet in contact with the heated surfaces. By closing the hole, the likelihood of debris and foreign objects getting inside the furnace body is reduced, the extraction of which would characterize the maintenance process of the device with increased labor intensity. By means of an additional metal sheet, an increase in the safety of operation of the device is ensured, since the additional metal sheet serves as a fence restricting the access of users to heated surfaces inside the furnace body during heating, which simplifies the operation of the device for taking hot baths, in particular, due to the absence of the need compliance with additional security measures.

A particular case of the implementation of the device involves the execution of the walls of the metal container at least three horizontal rows located at an angle to each other. The implementation of the capacity of the device for taking hot baths in this form increases the manufacturability of production, since it does not require the use of labor-intensive and energy-intensive metal processing technologies, such as rolling: the production of a faceted vat is preferably carried out by welding individual elements of the same type or flexible metal sheets. The use of metal sheets also increases the maintainability of the claimed device, since in the event of the formation of cracks during operation, they can be welded by welding. In case of deformation of the metal sheets and formation of dents, the metal sheets can in most cases be straightened without degrading the performance of the device and the need to replace its components.

The execution of the walls and bottom in this form allows you to create a device for taking hot baths closed in shape, similar to a hemisphere, which ensures the stability of the container relative to the axis of symmetry and evenly perceives the load, which increases the reliability of the device, and additionally provides comfortable and convenient placement of people in the internal volume during medical and hygienic procedures, since the faceted shape of the container, containing three horizontal rows, corresponds to the anatomical position of people in a sitting position, which also facilitates the operation of the device for taking hot baths.

As established by experience, the rigidity of the device is further increased due to the greater number of formed horizontal stiffeners that occur at the junction of flat trapezoidal faces, the smaller base of which mates with the large base of the trapezoidal face of the underlying row. The mutual conjugation of the trapezoidal faces by the sides forms additional vertical stiffening ribs.

The interface of the faces can be performed with the formation of ribs, since the stiffeners formed at the interface of flat trapezoidal faces located at an angle to each other significantly increase the rigidity of the structure, take on part of the load, increasing the resistance of the structure to the bending moment, thereby preventing its deformation, which ensures high reliability of the device for taking hot baths, reducing the need for repairs. The use of stiffeners additionally increases the manufacturability of the device, since it helps to reduce the cost of material for the production of the device, and also reduces its weight, since it provides the strength necessary for long-term operation with a smaller wall thickness. This also ensures the convenience of transportation and direct use of the device.

Elastic and plastic deformations, in particular, can occur during free movement of the fluid inside the cavity, the placement of people in it (including asymmetrical and uneven), the use of the walls of the container as a fulcrum during immersion in the container and exit from it, thus , can cause discomfort to users, so the elimination of deformations of the case by increasing its rigidity also makes the use of the device more convenient and comfortable.

Since the bottom of the metal container, which takes on part of the external load, can be made flat in the form of an equilateral polygon, the sides of which are conjugated with the lower bases of the trapezoidal faces of the lower row. The flat bottom is an easy-to-manufacture structural detail that does not require complex assembly operations in the manufacture of the container, which increases the manufacturability of the device. Making the bottom flat also characterizes the design by the presence of additional horizontal stiffening ribs at the junction of each side of the bottom with the lower ribs of the bottom row of the container. The device will be more stable about its central axis of symmetry, and its stability will not decrease with an increase in the number of horizontal rows or the number of faces in a row.

In addition, the flat bottom is most preferred for comfortable use of the hot bath apparatus, as it promotes the natural position of the human legs. In addition, after taking a bath, such a bottom is easily cleaned in preparation for the subsequent use of the device.
