Description

The utility model relates to equipment for washing dishes and can be used in catering both in cold and in hot water supply.

The closest technical solution (prototype) is a dishwasher (RF Patent No. 90311, A47L 15/00, publ. 10.01.2010), comprising a housing with a bath for washing and rinsing, washing and rinsing sprinklers, filter nets, and supply tube water to washing sprinklers, a water supply pipe to rinse sprinklers, an overflow pipe, a boiler, a drain chamber, pumps, as well as a control panel made on the front side of the body, above which there is a dome attached to the mechanism avnoveshivaniya, rear body panel is attached to the guide for moving the dome.

The disadvantage of the prototype: low reliability of the dishwasher due to frequent clogging of the washing sprayer and the inability to clean it, because the design of the washing sprayer is solid (non-separable), i.e. unrepairable.

The technical problem of the dishwasher is that over time, the washing sprinklers can become clogged with indelible food and dirt left in the bathtub, from which water is drawn by the washing pump, which pumps the washing solution onto the dishes through the washing sprinklers. If the washing sprinklers are not cleaned in time, limescale may also form inside the holes. The specified clogging with dirt characterizes the non-separable design of analog washing detergents that are not repairable, therefore, it is inconvenient and difficult to wash them from food debris, which leads to a decrease in the reliability of the operation of washing sprayers, therefore, reducing the overall reliability of the dishwasher.

The technical result of the utility model is to increase the reliability of the dishwasher, which is achieved by increasing the maintainability of the washing sprinklers.

The technical result is achieved by the fact that the dishwasher contains a housing with a bathtub for washing and rinsing, washing and rinsing sprinklers, filter screens, a water supply pipe to the washing sprinklers, a water supply pipe to the rinsing sprayers, an overflow pipe, a boiler, a drain chamber , pumps, as well as a control panel made on the front side of the case, over which there is a dome attached to the balancing mechanism, the back panel of the case is attached to for moving the dome, the washing sprinklers are made collapsible, each of which consists of an intermediate hollow element with cylindrical hollow tubes detachably entering into it from both sides, the ends of which are closed by spring-loaded plugs, and spherical concave hollows are formed on the upper surface of the cylindrical tubes, in which cross-shaped cutouts are made, at the end of each of the cylindrical tubes on opposite side surfaces at least two holes are made hirsty. Moreover, on the front side of the dome is made a rectangular hole with glass. Moreover, a lamp is built into the rear panel of the housing. Moreover, the intermediate element is made of non-metallic material. Moreover, the cylindrical hollow tubes are made of stainless steel. Moreover, the transverse cutouts of a curved shape are made in the form of eights. Moreover, each cylindrical hollow tube is made with at least ten transverse curly cuts. Moreover, all structural elements of the washing spray in the assembly state are made coaxial.

New significant distinguishing features of the proposed technical solution are the following:

- the implementation of collapsible washing sprinklers, each of which consists of an intermediate hollow element with cylindrical hollow tubes detachably entering into it from both sides, the ends of which are closed by spring-loaded plugs;

- execution on the upper surface of the cylindrical tubes of molded concave hollows, in which transverse cuts of shaped shape are made;

- execution at the end of each of the cylindrical tubes, on opposite lateral surfaces, at least two holes.

The combination of new significant distinguishing features with the features known from the prior art is sufficient to solve the indicated technical problem and to obtain the technical result provided by the utility model - to increase the reliability of the dishwasher by increasing its maintainability.

The dishwasher contains a housing 1 (Fig. 1) with a bath 2 (Fig. 2) located in it for washing and rinsing dishes, washing sprinklers 3 (Fig. 1) and rinsing sprinklers 4 that are attached to the riser (not shown in Fig. Not shown) ), overflow tube 5. Detergent sprinklers 3 and rinse sprinklers 4, with which washing and rinsing utensils are carried out, are made rotating. The filter nets 6 cover the bath 2 (Fig. 2) from above. The dishwasher also contains a tube 7 for supplying water to the washing sprinklers 3 (Fig. 1), a tube 8 (Fig. 2) for supplying water to the rinsing sprinklers 4 (Fig. 1), a drain chamber 9, (Fig. 2), a balancing mechanism 10 On the front side of the housing 1 (Fig. 1) is a control panel 11 having operation mode buttons that are connected to the controller (not shown in Fig.). Under the bath 2, behind the control panel 11, there are a boiler 12 (Fig. 2), a washing pump 13, a rinse pump 14, a water supply solenoid valve 15 and an electromagnetic shield (not shown in Fig.). On the electromagnetic shield there is a washing pump-dispenser 16 (Fig. 1) and a rinsing pump-dispenser 17. A dome 18 is located above the housing 1 of the dishwasher. On the front side of the dome 18, a rectangular hole 19 is made with a glass for viewing by the operator of the washing chamber (formed after lowering the dome 18). The housing 1 also includes a rear panel 20 with attached vertical guides 21 for moving the dome 18 up and down. The handle 22 is designed to raise and lower the dome 18. The dome 18, moving along the vertical guides 21, is attached to the balancing mechanism 10 (Fig. 2), made in the form of two springs. In the rear panel 20 (Fig. 1) of the housing 1 can be integrated lamp 23 (Fig. 2). The dishwasher is closed by facing panels: the rear panel 20 (Fig. 1) and the control panel 11 are removable, which allows qualified personnel access to the mechanisms located inside the dishwasher during the repair work.

The washing sprayer 3 shown in FIG. 1 and FIG. 3, has a collapsible design, consisting of an intermediate (solid) hollow element (body) 24 (Fig. 3), with two cylindrical hollow tubes 25 detachably included in it from two sides, which are fixed to it using fasteners 26, for example , screws M4 × 10 GOST 17475-80. The ends of the cylindrical hollow tubes 25 are closed with plugs 27 made of high pressure polyethylene LDPE according to GOST 16337-77. In cylindrical hollow tubes 25, plugs 27 are spring-loaded with elastic elements 28, for example, springs made of stainless steel 30 × 13 GOST 18143-72. The plugs 27 of the cylindrical hollow tubes 25 are sealed with spacer rings 29 made, for example, of food rubber according to TU 2539-001-49247031-2004. The intermediate hollow element (housing) 24 is made, for example, of polyamide PA6-210KS OST 6-11-489-79, and cylindrical hollow tubes 25 are made, for example, of stainless steel 12X18H10T GOST 11068-81. Each of the cylindrical hollow tubes 25 structurally has transverse cutouts 30 in the upper part of a curved shape, for example, in the form of eights (fillets) through which water is released during washing. The length (L) of the transverse cutout 30 of the figured cutout in the form of a figure eight (fillet) is, for example, 10 mm. The size (K) of the narrow portion of the fillet 30 is, for example, 3 mm. The size (M) of the wide portion of the fillet 30 is, for example, 5 mm. Each transverse cutout 30 of figured shape in the form of a figure eight is made in a spherical concave cavity 31 with a sphere diameter (H), for example, 95 mm. The spherical concave cavity 31 is made by stamping. The presence of a spherical concave cavity 31 allows you to form a better, more directed to the dishes stream of washing solution. The maximum depth (P) of the spherical concave cavity 31 on the cylindrical hollow tube 25 is, for example, 10 mm. Together on the upper surface of the two cylindrical tubes 24, for example, ten spherical concave depressions with a figure eight-shaped transverse cut 30 located in each of them are formed. Each of the transverse cuts 30 of a figured shape in the form of a figure eight acts as a nozzle for the jet of washing solution coming out of it. The presence of a narrow part of the fillet 30 allows you to increase the pressure of the washing solution passing through the nozzle. At the end of each of the cylindrical hollow tubes 25, on their opposite lateral surfaces, two holes 32 are made. All the structural elements of the washing sprayer in the assembly state are made coaxial.

The work of the dishwasher. The dishwasher has two washing modes, which differ in the duration of washing. The washing mode is selected by means of the operating mode buttons “1” or “2” (not shown in Fig.) Located on the control panel 11 (Fig. 1) of the front side of the housing 1. The washing process in the dishwasher is carried out according to the specified operating algorithm, including three stages: washing, curing, rinsing. The dishes intended for washing are installed on a special cassette (not shown in Fig.), Which is then installed in the dishwasher. To start the washing process, use the handle 22 to lower the dome 18 down to the stop. At the first stage of the washing process, the dishes are washed with the washing solution in the bath 2. The bath 2 is filled with water through the boiler 12 (Fig. 2). The metering pump 16 (Fig. 1) washing supplies a portion of detergent to the bath 2 filled with water, constantly maintaining the necessary concentration of the working (washing) solution in it. The rinse-off metering pump 17 supplies a portion of the rinsing agent to the water-filled boiler 12 (Fig. 2), constantly maintaining the necessary concentration of the working (rinsing) solution in it. The amount of detergent and rinse aid supplied is set by the controller (not shown in FIG.), Which controls the algorithm of the dishwasher. During washing, the filter nets 6 (Fig. 1), covering the top of the bath 2, prevent large food debris from entering the bath 2. The washing pump 13 (Fig. 2) takes the finished washing solution out of the bath 2 (Fig. 1) and through the tubes 7 (Fig. 2) the water supply delivers it to the upper and lower washing sprinklers 3 (Fig. 1, 3), which, rotating due to the side holes 32 in the cylindrical hollow tubes 25 (Fig. 3), transmit a directional shape from transverse cuts 30 of a shaped shape in the form of eights located in formed spherical concave hollows, a jet of washing p solution on the dishes. At the second stage of the washing process, exposure (pause) is carried out to remove residual detergent from washing sprinklers 3 (Figs. 1, 3) and from dishes. In the third stage, the dishes are rinsed with hot water coming from the boiler 12 (Fig. 2), into which rinsing agent is added, through the water supply pipes 8 to the upper and lower rinsing sprinklers 4 (Fig. 1), which rotate, direct a dense stream of their nozzles on the dishes. In turn, hot water is pushed out of the boiler 12 (Fig. 2) by the water coming from the water supply network by opening the solenoid valve 15. The rinse pump 14 (Fig. 1) is integrated in the rinse line of the dishwasher to improve the rinse quality. Water is drained from the bathtub 2 to the sewer after rinsing using an overflow tube 5. The operator can carry out visual control of the washing process through a rectangular hole 19 with glass, made on the front side of the dome 18, and due to the presence of a lamp 23 (Fig. 2), integrated in the rear panel 20 (Fig. 1), visual control of the washing process is facilitated. At the end of the washing process due to the presence of the balancing mechanism (springs) 10 (Fig. 2) in the machine structure, the operator, without applying much effort raises the dome 18 (Fig. 1), moving along vertical guides 21 attached to the rear panel 20, and then removes the dish rack. Water is drained from the bathtub 2 of the dishwasher by removing the overflow tube 5 from the bathtub 2 through the drainage chamber 9 (Fig. 2). A constant concentration of washing and rinsing solutions during each stage of washing is supported by a dosing pump 16 washing (Fig. 1) and a dosing pump 17 rinsing. As a washing solution, a mixture of water and detergent can be used, which is, for example, Biol PM-automatic. As a rinsing solution, a mixture of water and rinsing agent can be used, which is, for example, Biolight OP-95PM.

In contrast to the prototype, where the washing sprayer is made integral, in the proposed technical solution due to the change in the design of the washing sprayer it is collapsible. If the washing sprayer becomes clogged, the dishwasher operator can independently clean the clogged holes by first disassembling the washing sprayer from the riser (not shown in Fig.), Disassembling it (removing the fasteners, springs and plugs from both ends), washing holes with water (or cleaning with wire ), and then collecting and installing the dishwasher on the riser. The use of a collapsible design of the washing sprayer with the possibility of its subsequent assembly solves the common problem that the operator faces during the operation of the dishwasher, i.e. when the washing sprayer is clogged, it is not necessary to replace it with a new one, which increases the maintainability of the washing sprayer and, consequently, the reliability of the dishwasher as a whole.

Also, in the proposed technical solution, due to the new design of the washing sprayer, namely, the presence of spherical concave depressions made by stamping on the upper surface of the cylindrical tubes and the implementation of figure-shaped transverse cuts in the form of eights in the formed spherical concave depressions, the pressure of the washing solution increases, which improves the quality of cleaning dishes from food debris, dirt and limescale, thereby increasing the reliability of the dishwasher as a whole.

The implementation of the proposed utility model allows to solve the claimed technical problem and ensure the achievement of the claimed technical result.

The proposed technical solution does not explicitly follow from the prior art. In the prior art, no analogue was found, characterized by features identical to all the essential features of the claimed utility model. Testing the device as a whole confirms its feasibility with the achievement of the claimed technical result, in this regard, the utility model meets the patentability condition “industrial applicability”.
