Description

Device for humidification and washing of air, designed for placement on horizontal surfaces

The utility model relates to household devices for washing and humidifying drum-type air in which a vertical gulf of water is provided.

It is known that devices for washing and humidifying drum-type air contain plastic disk evaporators that are constantly in motion. Under the drum is a tray with clean water. Rotating, the disks are washed with water, and the fan pumps room air onto them, which is cleaned while moistening. In this case, the source air can be passed through disks moistened with water if they contain filter material, or pumped onto disks if they contain material that forms an aqueous film of the required thickness upon wetting. Given the principle of operation of the device, informing the user about the sufficient or insufficient amount of water in the pan is necessary for the uninterrupted wetting of the disks, which means ensuring uninterrupted and effective cleaning and humidification of the air.

To inform the user about the amount of water in such devices, the use of sensors is known. For example, a device for humidification of air (RU2688297, 2009) is known, comprising a perforated mesh immersed in a water tank and vibrated as a drip generator, a valve mechanism for filling the tank and a lower level sensor for filling the water in the tank connected thereto, having two electrodes and signaling the detection of a zero water level.

Water level sensors can be used in devices for washing and humidifying any type of air, including drum type (for example, described in Korean application KR20100078914, published in 2010).

At the same time, the installation of electric or electronic sensors complicates and increases the cost of the design of the device as a whole, because requires the installation of additional elements of the electrical connection, as well as their maintenance.

Known devices that inform the user about the water level in the tank by using the buoyancy of the indicator, which is equipped with decorative elements. For example, a humidifier with a mechanical water level indicator (CN208536234, 2019) is known, the upper end of which is pivotally fixed to the outer pipe, and the lower end is free. When water is added to the device, the free end touching the water boundary raises the indicator up. At the same time, the curved curved elements connected with it in the form of petals are set in motion, therefore, when the tank is completely filled with water, the petals are above the upper boundary of the humidifier body and are fully opened like a flower.

The known device uses buoyancy of water to raise the indicator, which is, in fact, a float valve, which, in contrast to the use of sensors, simplifies the device as a whole. Nevertheless, the indicator in the specified device occupies a large internal volume, which makes it difficult to use it in devices for cleaning and humidifying drum-type air.

Closest to the claimed utility model, selected as a prototype, is a device for humidification and air washing, designed to be placed on horizontal surfaces (RU190252, 06/25/2019), containing a housing with supporting elements, inside of which there is a power source, a control unit with a printed circuit board, which is electrically connected to a power source and a control panel located on the outside of the housing wall and provided with controls, a fan located in the inner cavity of the housing for forced movement of the air flow entering through the air intake hole located in the housing, a water tank housed in the housing opposite to the fan with a converting element in contact with water to generate water dust, outlet openings located on the sides of the housing, in the side of the cavity a vertical tube for water inlet with through lateral holes for water to flow into the water tank is installed, a float valve is placed inside the tube, the lower part of which is out um beyond the lower edge of the tube, the lower end of the float valve and the bottom of the water tank installed with a gap relative to each other, and the float valve has a length such that when it is moved upward through the overlap allows lateral tube openings.

In the prototype device, the role of the indicator of maximum water filling is a float valve, which pops up when an excess volume of water appears. The use of a float valve in a tube for water filling is a simple and compact solution - a mechanical indicator is simpler to execute than electronic and does not occupy a separate place in the interior of the device. However, for the user, an indication of the water level in the device is not always effective, because The user regularly needs to come close to the device and examine the position of the float valve in the water inlet, which requires the user to have good vision and labor. To eliminate this drawback, for example, by modifying the float valve so that the indication of the water level is carried out above the boundary of the upper part of the housing, it is not possible in the known design, since in this case, the hole for the gulf of water will partially overlap, which complicates the smooth operation of the device. In addition, the known indicator does not report intermediate values of the water level in the water tank, because The known design provides an indication of only excessive volume of water, i.e. the consumer is effectively informed only about the water level with the maximum filling of the water tank.

The objective of the utility model is to provide effective mechanical indication of changes in water level in devices for washing and humidifying air by placing an autonomous compact float in the body cavity.

The technical result is an increase in the efficiency of indicating changes in the water level in devices for washing and humidifying air during its remote control while reducing labor costs for servicing the device.

 The problem is solved by the fact that the claimed device for humidification and washing of air, designed to be placed on horizontal surfaces, including a housing having a tray and a removable upper part made with the possibility of intake air and outlet openings for the release of cleaned and moistened air, the body cavity on the pallet contains a water tank with a converting element, which when in contact with water generates water dust, a fan is installed opposite to the water tank, in the cavity the casing contains a vertical tube for water inlet, one end of which is directed to the water tank, and the other end is led out to the opening of the upper part of the casing, a mechanical water level indicator made in the form of a float valve, the upper part of the casing contains a control panel with controls, a control unit connected to the controls and a power source, characterized in that in the water tank outside the vertical tube for water inlet, a vertical mount is installed, the free end of which has a thickening, the float valve with its lower part interacts with the vertical fastener with the possibility of restricting the stroke of the float valve to the aforementioned thickening, a hole is made coaxially to the vertical fastener in the upper part of the body to make a rod with a head detachably connected to each other, the lower end of the rod interacts with the float valve, the rod is made with length, providing the ability to move the head above the surface of the housing.

The vertical mount to accommodate the float valve is preferably made of the same material as the water tank. One end of the vertical mount is permanently connected to the bottom of the water tank. Preferably, the water tank and the vertical mount are made by molding plastic using a matrix, which provides for the formation of a vertical mount with a thickening in its upper part. The permanent connection of the vertical mount to the water tank can be carried out by means of adhesive bonding or soldering when heated.

The thickening of the vertical mount preferably has a mushroom shape, the lower edge of which forms a contact area for interaction with the side walls of the float valve, restricting its movement when moving upward under the action of a buoyancy force. The thickening of the vertical mount performs the function of the catch of the float valve when moving along the center line of the vertical mount, prevents the float valve from disconnecting when moving up and down.

The float valve, the rod and the head detachably connected to the rod are hollow and preferably have a cylindrical forming surface.

The float valve is made hollow to allow lifting under the action of the buoyancy force of the water in the water tank. The float valve may have a different shape, providing the ability to move up and down under the action of the buoyancy force. The float valve is made of materials whose density is lower than the density of water, for example, plastic that does not swell in water.

The rod is mounted on the upper part of the float valve and placed coaxially with it. The stem can be made of the same plastic as the float valve. The rod is made with a length allowing movement of the head connected to it above the surface of the housing, preferably to the height of the float valve.

The detachable connection of the head and the rod can be performed, for example, by performing in the lower part of the head of the protrusion, which is made with the possibility of connecting the extension with the inner generatrix of the cavity of the rod. The head is made with a width exceeding the diameter of the rod.

The head is preferably made of the same plastic as the shaft.

Color or text information signs can be applied to the head, informing the consumer about the water level in the water tank, because at maximum filling of the water tank with water, the head protrudes above the surface of the housing due to the movement of the rod through the hole made in the housing cover. And in the absence of water in the water tank, the head contacts the cover of the upper part of the body. To place the head flush said hole may be provided with a niche.

When the water level is low, the head connected to the rod interacting with the float valve is lowered and does not protrude beyond the boundaries of the housing surface. With the maximum capacity of the water tank, the head protrudes above the surface of the housing.

The upper part of the housing is connected to the pallet, for example by means of grooves located in the pallet, and is fixed to the pallet by engagement. The consumer has the opportunity to remove the upper part of the housing and clean the pan with a water tank. At the same time, the claimed design of the float valve with a stem and a removable head does not interfere with such a separation of the housing parts.

The upper part of the housing has a cover in which a hole is made for placing a vertical tube for pouring water into the water tank, and a hole with a niche is made coaxially with the vertical fastening to accommodate a rod interacting with the float valve and equipped with a removable head.

When in contact with water, the conversion element generates water dust, for example, a disk conversion element generates water dust by mechanical dispersion of water, and can be made of polyethylene terephthalate or polyethylene or from ABS plastic or other similar plastic materials that are not subject to corrosion. When in contact with water, a disk converting element holds water in its form in the form of finely dispersed water droplets due to the ribbed surface of the converting element, which can be formed by not through niches, protruding partitions over the area of the converting element, by fibrous lines forming a mesh structure. Other known converting elements may also be used that provide vibration or circulation when in contact with water, as well as heating water or water suspension (aerosols).

The fan pumps a stream of incoming air, which comes into contact with fine droplets of water, the air is humidified, it is cleaned under the influence of rotating streams, the impurities are lowered on the bottom of the water tank, and the cleaned and moistened air is discharged through the outlet openings located in the housing.

The interior of the housing between the disk converting element and the fan forms an air chamber. In the zone of the air chamber on the lateral or upper surfaces of the casing there are outlet openings for the exit of humidified and purified air.

The electrical connection is represented by a power circuit implemented by conductive wires, electrical contacts, conductive paths on a printed circuit board and other known elements of electrical circuits.

The control unit is located inside the housing and is connected to the mains by means of a power supply unit and a power cord. The control unit contains a printed circuit board with radio elements, a microcontroller or microprocessor, may additionally contain a hygrostat and other controls and indications.

The control panel, located on the outside of the case, has controls, and may also contain a window for the information display.

Holes for air intake from the room can be placed in the lower or upper part of the housing.

Near the air intake can be placed elements of temperature and humidity control, interacting with the flow of incoming air. These control elements can be represented by a thermometer and a hygrometer, configured to transmit data to the microcontroller of the control unit.

The supporting elements of the main body can be retractable, which increases the area of the support and gives additional stability to the device, both in the process of pouring water and subsequent operation.

Comparison of the claimed device with the prototype shows that it differs in the following features:

- in the water tank is installed a vertical mount located outside the vertical tube for water inlet,

- the float valve with its lower part interacts with a vertical mount,

- the free end of the vertical mount has a thickening restricting the stroke of the float valve;

- the float valve with its upper part interacts with a rod having a removable head;

- in the upper part of the housing there is a niche with a hole for placing a rod with a head, placed coaxially with vertical mounting,

- the rod is made with a length that provides the ability to move the head above the surface of the housing.

Comparison of the claimed device with the known allows us to conclude that the criterion of "novelty".

The inventive device can be made of known materials using known technologies and known structural elements, which allows us to conclude that the criterion of "industrial applicability".

The inventive utility model is illustrated by the following example of a specific implementation and is shown in the following figures.

Figure 1 schematically shows the float valve assembly;

In FIG. 2 schematically shows the layout of a vertical tube for water inlet and a float valve in the inventive device;

In FIG. 3 schematically shows the operation of the float valve in the device.

The inventive device consists of a housing containing a pallet 1 and an upper part 2, detachably connected to the pallet 1, the conditional boundary between which is indicated by a dashed line (Figure 3). On the pallet 1 there is a water tank 3, on the bottom of which a vertical fastening 4 with a thickening 6 is made to accommodate the float valve 5. The thickening 6 is made mushroom-shaped and acts as a latch restricting the stroke of the float valve 5. The height of the vertical fastening 4 is comparable to the height of the tank for water inlet 3. The float valve 5 in the upper part interacts with a cylindrical hollow core 7, detachably connected to the head 8, which is connected with its lower protrusion to the internal cavity with rod 7. A hole (not shown) is made in the cover of the upper part of the housing 2, placed coaxially to the vertical mount 4, with a niche (not shown) to accommodate the rod 7 with the head 8. Another cover 9 is also made in the cover of the upper part of the housing 2 to accommodate the vertical tubes 10 for pouring water into the water tank 3. The disk converting element 11 is mounted on the pallet 1 in special grooves and rotates due to the gear connection and rotation of the engine gears and gears mounted on the axis of the disk converting element 11. a fan 12 is located in the cavity of the housing, through which the air entering through the air intake openings (not shown) made in the housing cover is forcibly moved into the cavity of the device, mixed with fine particles of water, cleaned and sent through the outlet openings (not shown) of the housing to the room. The fan 12 and the disk converting element 11 through the control unit to an electrical power source (not shown).

The inventive device operates as follows.

A device for washing and humidifying the air is included in the network. In a vertical tube 10 for filling water from above, water is poured. When water is filled, due to the rising water level in the water tank 3, the float valve 5 rises up along the axis of the vertical fastening 4. When the maximum water level in the water tank 3 is reached, the side walls of the float valve 5 abut against the lower edge of the bulge 6, stopping his move. Accordingly, the movement of the rod 7 with the head 8, protruding above the housing cover and equipped with indicative marks, stops. By the appearing inscriptions or color indicators on the head 8, the user receives information about the water level in the water tank 3.

When water evaporates, its level in the water tank 3 decreases, and the float valve 5 lowers, respectively, the head 8 also lowers, and text or color indicators on it indicate a change in the water level. If the water level drops to zero, then the float valve 5 lowers on the bottom of the water tank 3, and the head 8 rests on the surface of the housing cover in a niche (not shown).

The disk converting element 11 is in contact with water poured into a water tank 3, and, rotating, breaks it into tiny particles, forming water dust, which rises into the air chamber. The fan 12 pumps the incoming air from the room through an air intake hole (not shown) into the air chamber, where the inlet air stream and water dust are mixed. As a result of the rotation of the disk converting element 11 and the joint movement of the flows in the air chamber, the air, cleaned from dust and enriched in the water phase, is blown into the room through the air outlet openings (not shown). Dust particles settle on the bottom of the water tank. Periodically, the device is cleaned of contaminants by removing the removable upper part of the body and washing the water tank 3.

Thus, the use of the inventive device provides simultaneous humidification and air washing, expanding the range of compact stand-alone devices designed for placement on horizontal surfaces and with the ability to indicate the water level.

In addition, when using the inventive device, the user can obtain information about the intermediate values of water filling, and not only about the maximum filling, as in the device of the prototype. Thus, the claimed solution improves control of the smooth operation of the device for washing and humidifying the air, i.e. increases the effectiveness of the indication of changes in water level in the process of its remote control. Also, the inventive device reduces labor costs for the maintenance of the device.
