Abstract

The utility model relates to a dishwasher drying device, which comprises a casing, and a blower, a heating element and an air supply device which are positioned in the casing in sequence, wherein the heating element is arranged at the outlet of the blower, the air supply device comprises an air duct body and a body cover plate, and an air port is arranged in the central section of the air duct body. Because the blower absorbs cold air, after the heating element heats the cold air, the hot blast enters into the inner shell of the dishwasher from the air port through the air duct body, to dry tableware and the walls of the inner shell, the hot blast is mobile during the drying process, thereby the drying efficiency is high, the electric energy is saved, and the use is also very convenient.

Description

The dish-washing machine drying unit

1. technical field

The utility model is a kind of drying unit, particularly a kind of dish-washing machine drying unit.

2. technical background

Along with people's living standard improves constantly, dish-washing machine has progressed into family, but present most dish-washing machine is after washing, or there is not special drying unit to tableware and inner bag oven dry, and just utilize the waste heat of the hot water that washes the dishes to dry, and drying time is longer, and efficient is lower; Or the employing infrared facility is realized the oven dry to tableware and inner bag, owing to infrared facility is the purpose that tableware and inner bag heating is reached oven dry by heat radiation, therefore steam is difficult for flowing in the internal cavity of bowl washer, drying efficiency is not high yet, and power consumption is more, has influenced the universal use of dish-washing machine.

3. summary of the invention

The purpose of this utility model provides a kind of easy to use, saving electric energy, the dish-washing machine drying unit that drying efficiency is high.

The technical scheme that realizes the utility model purpose is: it includes shell, places blower fan, heater element and air supply device in the shell successively, heater element is located at the blower fan outlet, air supply device is made up of air channel body and body cover plate, and the air feed mouth is established at body middle part in air channel.

When the utility model uses, the impeller of blower fan is aimed at the bottom of dish-washing machine, the air feed mouth is communicated with internal cavity of bowl washer, and its good effect is: because blower fan sucks cold wind, after heater element is with the cold wind heating, hot blast enters internal cavity of bowl washer by the air feed mouth at air channel body middle part, with tableware and the oven dry of inner bag wall, hot blast flows in the drying course, so the drying efficiency height, save electric energy, use very convenient.

4. description of drawings

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is stereograms of the utility model air channel body;

Accompanying drawing 3 is user mode schematic diagrames of the present utility model.

5. the specific embodiment

Below in conjunction with drawings and Examples structure of the present utility model and use are described further.

It includes the utility model shell 1, places blower fan 2, heater element 3 and air supply device in the shell 1 successively, heater element 3 adopts PTC assembly or heating wire or other thermo electric material, be located at blower fan 2 outlets, air supply device is made up of air channel body 4 and body cover plate 5, body 4 middle parts in air channel are provided with heart-shaped wind deflector 8, they are as a whole, itself can prevent the sealing infiltration, the apex of the heart part of heart-shaped wind deflector 8 is over against heater element 3, the heating of heater element 3 is by temperature controller 7 controls, and wind deflector 8 central authorities establish air feed mouth 10.When the utility model uses, air feed mouth 10 is communicated with internal cavity of bowl washer, the impeller 6 of blower fan 2 sucks cold wind during work, after heater element 3 is with the cold wind heating, hot blast is divided into two strands by heart-shaped wind deflector 8 and moves up, two strands of hot blasts converge after the heart bizet of heart-shaped wind deflector 8 enters internal cavity of bowl washer by air feed mouth 10, with tableware and the oven dry of inner bag wall.Because the effect of heart-shaped wind deflector 8, the pressure loss is little during air channel body 4 air intakes, and air-flow is even, and noise generated by air flow is little.

In order to make the air channel body have sealing function, can prevent that the spray that internal cavity of bowl washer splashes from entering air supply device when washing, can prevent that again thermal current is directly from air channel body discharge inner bag, establish a barrier plate 9 at the rear of the middle part of heart-shaped wind deflector 8 air feed mouth 10, barrier plate 9 and the heart-shaped wind deflector 8 common cavitys that constitute a lower end sealing, upper end open, the upper end open of this cavity communicates with air feed mouth 10.Like this, barrier plate 9 can allow hot blast enter internal cavity of bowl washer by air supply device with the heart-shaped wind deflector 8 common cavitys that constitute, and can stop spray to enter air supply device by air feed mouth 10 again; Simultaneously, when the utility model quits work, even there is the damp-heat of internal cavity of bowl washer to flow to into the air channel body, because thermal current density is less than cold air density, therefore damp and hot air-flow can not move down from air channel body upper end, prevents that air-flow from overflowing, high insulating effect.If dish-washing machine is a high-temperature wash like this, then need not conducting heater element 3, directly utilize the surplus temperature behind the internal cavity of bowl washer high-temperature wash, start blower fan, tableware in the dish-washing machine and inner bag wall can be dried up in the short time.Very save electric energy.

The utility model also can be provided with program controller and whether reach fever time with the work of control heater element according to dish-washing machine real work situation and instructions for use.
