Description

The utility model relates to household appliances, namely to electric fireplaces that simulate the burning of fire and smoke.

The prior art various types of electric fireplaces that create an imitation of burning fire, some of them additionally have the function of simulating smoke.

The known solution "Device for creating the flame effect", patent No. EP 1703211, 02/10/2005.

One of the closest solutions is the “Smoke Effect Generator” (WO 2003/063664). This device contains a liquid container, an ultrasonic transducer located inside the container, located above and at some distance from the transducer of the perforated substrate, and means for moving air upward from the substrate. The description also discloses the presence on the substrate of one or more blocks of material, mainly simulating burning materials, such as wood or coal.

As the closest analogue adopted "ELECTRIC HOUSE", the technical solution for the patent of the Russian Federation No. 2434181, BASIC HOLDINGS. This device with the effect of simulating a flame includes a substrate with holes; a light source that creates a flame effect; a container containing liquid, and in this container there is a space above the liquid level, including a vapor exit channel; an ultrasonic transducer whose transforming surface is in contact with the liquid and which forms steam in the indicated space above the liquid level; means for generating an air flow along a path entering the space above the liquid level and passing through the steam outlet channel, wherein the exit channel is positioned so that air leaves the container under the substrate with openings; and means for generating an upward flow of air from the substrate with holes.

As the closest analogue, as well as a number of other technical solutions mentioned above, have a number of drawbacks caused mainly by the presence of holes and, more generally, by the design itself, which assumes the presence of a uniquely placed substrate in the housing.

These disadvantages include the following:

- weak "penetrating ability" of the aerosol when passing through these holes. Some part of the generated aerosol, "leaving the container under the substrate with holes", settles / condenses on the lower part of such a substrate. In addition, the physical obstacle created by the substrate for the cold aerosol flow to escape until the case is warmed up entails the draining and accumulation of water suspension in the case and, as a result, corrosion of not only the parts of the case, but also the possibility of closing the lamp contactors;

- the possibility of clogging holes, especially with prolonged use;

- the complexity of changing the appearance of imitations of firewood / coal, since the location of the holes in the substrate cannot be changed; in this case, if the simulations are removable, it is necessary to take into account the location of the holes in the substrate - otherwise randomly placed simulations of firewood / coal will impede the passage of aerosol flows to a large extent;

- insufficient draft for the aerosol provided either by convection flows only from the “means of forming the air stream”, which are lamps that are heated during operation, or by the need to install an additional means of forming such a stream in the form of a fan. The fan in devices known from the prior art can provide sufficient traction, but at the same time, it requires additional energy and creates additional unwanted noise of a working system;

- insufficient illumination of the escaping aerosol through existing openings and crevices.

The objective of the proposed device is to eliminate the many disadvantages of analogues; the technical result is the creation of an electric hearth, economical in production and work, creating an improved imitation of flame and smoke, a hearth that creates sufficient traction for free passage of aerosol to the upper part of the body; a source in which the generated aerosol does not settle on the lower parts of the simulation elements of burning materials, which prevents corrosion of the housing parts and the possibility of closing the lamp contactors; hearth, the design of which prevented the possibility of deterioration in the quality of imitation of flame and smoke due to clogging; a hearth, the design of which provides increased illumination of the aerosol that passes through the space between the simulation elements of burning materials; as well as improved capabilities for customizing the appearance of the electric focus.

The proposed solution eliminates the above disadvantages due to the next implementation of the electric fireplace.

Electric fireplace consists of a body and elements placed in the body:

- a reservoir, wherein the reservoir contains an aerosol exit channel. Hereinafter, a reservoir should be understood to mean any container structurally constructed with the ability to retain a certain amount of gas or liquid (mainly liquid), sufficient for the subsequent creation of aerosol from it / her;

- means of creating an aerosol simulating flame and smoke. By aerosol, hereinafter, we mean a dispersed system consisting of suspended in a gaseous medium, mainly in air (based on the purpose and normal use of the product), small particles, mainly from liquid droplets (also often referred to as fog);

- a light source that creates the effect of flame and / or smoke;

- at least two panels intended for placement on them;

- elements simulating burning materials and placed separately from each other.

Also, the electric fireplace may include a screen made of a transparent material.

The proposed solution is illustrated by drawings. Figure 1 shows an electric fireplace, where the following items are indicated: 1 - body, 2 - screen (partially shown), 3 - a tank designed to accommodate liquid; 3a - aerosol exit channel, 4 - light source, 5a and 5b - elements of imitation of burning materials (shown conditionally). For ease of understanding, the housing is shown without a top and side wall. The aerosol generating means placed inside the tank is not shown.

Elimination of the above disadvantages is ensured mainly due to the rejection of a single substrate with holes in it and the use of two or more elements of imitation of burning materials (firewood / coal), creating the effect of a real hearth.

An advantageous type of arrangement is the placement of two elements simulating burning materials in one plane in the middle part of the housing, separately from each other. Options may be the placement of a different number of elements simulating burning materials at different heights from the base of the housing, while they can be installed both parallel to the base of the housing and at different angles of inclination to it. Embodiments are shown in Figures 2-8 (the device is shown schematically, without a significant number of components).

Stable placement of elements simulating burning materials inside the housing is achieved by known methods of fastening such elements, for example, on shelves attached to the side walls of the housing, ledges, due to detachable types of fastening, for example screw.

The type of execution of the elements of imitation of burning materials themselves is unprincipled to achieve a technical result; they can be made both flat and volumetric elements, that is, with a difference in height dimensions relative to the length / width not exceeding one order (for example, the height will be 3 cm, length - 50 cm).

It is also not fundamental and the shape of the elements of imitation of burning materials in the plan (when viewed from above) can vary; the predominant form is a flat sheet or parallelepiped. However, geometrically inaccurate shapes of imitation elements of burning materials in the plan are possible, for example, with different dimensions of opposite sides, with thickening of individual sections in the plan, and so on. There is also no need to make elements of simulating burning materials the same, the second element may differ in shape from the first, and also, if applicable, from the third and subsequent elements.

Various types of plastics are mainly used as materials for simulating burning materials, but wood or metals, as well as composite materials, can be used.

When you turn on the electrical source of the electric source and provided that the reservoir 3 is filled with the necessary amount of liquid, mainly water, the aerosol generating means begins to work in the reservoir 3.

As a means of creating an aerosol, for example, an ultrasonic transducer can be used, the converting surface of which is in contact with the liquid and which forms an aerosol that enters the space of the housing 1 through the aerosol exit channel 3a.

Further, under the influence of convection air flow generated by heating the air with working lamps 4 installed mainly on the base of the housing 1, the aerosol moves into the space between the simulation elements of burning materials 5a and 5b, while being illuminated by the same lamps. The number of lamps 4 depends on the particular type of implementation of the electric source, mainly from 1 to 8 lamps are used; lamps can be selected both from natural light and with different emitted parts of the spectrum, due to which it is possible to obtain portions of a moving aerosol illuminated in various colors.

Due to the presence of such a thrust directed into the free space, the aerosol does not settle on the lower parts of the simulation elements of burning materials 5a and 5b, at least the amount of aerosol entering the upper part of the housing 1 is much larger than in the known analogues.

Accordingly, the possibility of runoff and accumulation of water suspension in the housing is eliminated, or at least significantly reduced, which prevents both premature corrosion of parts of the housing and the possibility of closing lamp contactors.

The absence of small openings (of the order of millimeters) in the structure naturally prevents the openings from clogging, that is, reducing the quality of imitation of flame and smoke; the proposed design, even in the case of a significant clogging of the edges of the simulation elements of burning materials, does not change its characteristics in this parameter.

Also, the absence of small openings for the passage of the aerosol increases the illumination of the aerosol passing through the space between the simulation elements of the burning materials 5a and 5b. The presence of such a space, in turn, allows you to create sufficient traction for free passage of aerosol to the upper part of the housing without increasing the temperature in the lower part and without the need to place additional devices to increase traction, for example, fans in the upper or lower parts of the housing.

Additional advantages to the above are given by the embodiment of the electric source, which is completely similar to the above, with the addition of material for execution or coating of simulation elements of burning materials.

As mentioned above, one of the most significant drawbacks of existing devices is the lack of traction, due to which the aerosol is lifted from the reservoir towards the upper part of the housing.

The above design already largely eliminates this drawback. However, a further increase in traction due to the design of the source and changes in the relative positions of the elements is difficult. On the other hand, a further increase in traction is possible due to the implementation of all or parts of the simulation elements of burning materials, or at least parts of their lower surfaces from materials having high heat capacity values. A similar effect can be achieved by coating imitation elements of burning materials made of common plastics or metals with high heat capacities.

The main effect on the increase in traction in the proposed design is the lower surface of the elements of the simulation of burning materials. In this regard, the element for simulating burning materials can be made composite, for example, from two parts, the upper and lower, while the upper part can be made of any material suitable for simulating combustion, and the lower part is made, for example, of metals with a high thermal conductivity and heat capacity.

Thus, the most obvious option (and one of the most economical) is to make or cover at least some sections of the lower surfaces of the elements of simulation of burning materials (mainly the entire lower surface, or the lower part of the composite element) with black material, for example, polymer or another black paint.

This design creates the effect of a heat accumulator, in the role of which elements of imitation of burning materials are used (or at least one of the elements), which provides good traction due to the enhanced convective flow of heated air, which, in turn, draws out the aerosol more intensively (virtually no heat) to create an imitation of smoke and flame. The heating of such a heat accumulator occurs not only due to convective flux from the lamps, but also from the infrared radiation of the lamps, which can significantly reduce the time the entire electric fireplace system goes into operation, as well as extend the life of the system as a whole.

In addition, in existing analogs, a substrate with holes, after starting operation and heating, creates an additional obstacle in the form of a continuous horizontal thermal curtain, which is an obstacle for uniform heating of other parts of the wood / coal simulation above the perforated substrate. From this it follows that, passing through the perforation, the aerosol heats up much more strongly, and in contact with simulators of burning materials, which do not get infrared radiation from the lamps and convective flow, will condense on colder visualization elements.

Also, the presence of such an implementation allows you to provide another additional beneficial effect of the design. In models existing on the market, after shutdown, moisture located inside the structure simply settles on the case. In the proposed device, the lower part of the simulated burning material element, heated during operation, after being turned off, promotes drying and dehydration of the space above the lamps.
