Abstract

The utility model relates to a drying device for a dishwasher, which comprises a casing, a fan placed in the casing sequentially, a heating element and an air supply device, the heating element is arranged at the outlet of the fan, and the air supply device consists of an air duct body and a body cover. Composed of plates, the middle part of the air duct body is provided with an air supply port. Because the fan inhales cold air, after the heating element heats the cold air, the hot air enters the inner container of the dishwasher through the air duct body from the air supply port, and dries the tableware and the four walls of the inner container. During the drying process, the hot air is flowing, so drying It has high efficiency, saves electric energy, and is very convenient to use.

Description

dishwasher drying unit

1. Technical field

The utility model relates to a drying device, in particular to a dishwasher drying device.

2. Technical Background

With the continuous improvement of people's living standards, dishwashers have gradually entered the family, but at present most of the dishwashers do not have a special drying device to dry the tableware and inner tank after washing, but only use the washing machine to wash the dishes. The waste heat of hot water is used for drying, the drying time is longer and the efficiency is low; or the infrared device is used to dry the tableware and inner container, because the infrared device relies on heat radiation to heat the tableware and inner container to achieve drying. Therefore, the water vapor in the dishwasher liner is not easy to flow, the drying efficiency is not high, and the power consumption is high, which affects the popular use of the dishwasher.

3. Contents of the invention

The purpose of the utility model is to provide a dishwasher drying device which is convenient to use, saves electric energy and has high drying efficiency.

The technical solution for realizing the purpose of the utility model is: it includes a casing, a fan placed in the casing in turn, a heating element and an air supply device, the heating element is arranged at the outlet of the fan, and the air supply device is composed of an air duct body and a body cover plate. An air supply port is provided in the middle of the air duct body.

When the utility model is used, the impeller of the fan is aligned with the bottom of the dishwasher, and the air supply port is connected with the inner tank of the dishwasher. Its positive effect is that: the fan sucks the cold air, and after the cold air is heated by the heating element, the hot air flows through the air duct The air supply port in the middle of the main body enters the inner tank of the dishwasher to dry the tableware and the four walls of the inner tank. During the drying process, the hot air is flowing, so the drying efficiency is high, energy is saved, and it is very convenient to use.

Accompanying drawing 2 is the perspective view of the utility model air duct body;

Accompanying drawing 3 is the use status schematic diagram of the utility model.

5. Specific implementation

Below in conjunction with accompanying drawing and embodiment the structure of the present utility model and use are described further.

The utility model includes a casing 1, a fan 2 sequentially placed in the casing 1, a heating element 3 and an air supply device. The heating element 3 adopts a PTC component or an electric heating wire or other electric heating materials, and is located at the outlet of the fan 2. The air supply device It is composed of the air channel body 4 and the body cover plate 5. There is a heart-shaped air deflector 8 in the middle of the air channel body 4. They are a whole and can prevent water penetration. The apex of the heart-shaped air guide plate 8 is facing the heating element 3 , The heating of the heating element 3 is controlled by the temperature controller 7, and the center of the air deflector 8 is provided with an air supply port 10. When the utility model is in use, the air supply port 10 is connected with the inner container of the dishwasher, and the impeller 6 of the fan 2 sucks cold air during operation. After the cold air is heated by the heating element 3, the hot air is divided into two strands by the heart-shaped air deflector 8 and moves upward. After the two strands of hot air converge, the heart crown of the heart-shaped air deflector 8 enters the dishwasher inner container from the air supply port 10, and the tableware and the four walls of the inner container are dried. Due to the effect of the heart-shaped air deflector 8, the pressure loss of the air duct body 4 is small when the air enters, the air flow is uniform, and the noise generated by the air flow is small.

In order to make the air duct body have a sealing effect, it can not only prevent the water spray splashed by the dishwasher liner from entering the air supply device during washing, but also prevent the hot air flow from directly discharging the inner liner from the air duct body. A baffle plate 9 is arranged behind the air supply port 10 in the middle. The baffle plate 9 and the heart-shaped air deflector 8 jointly form a cavity with a sealed lower end and an open upper end. The upper end opening of the cavity communicates with the air supply port 10 . In this way, the cavity formed by the blocking plate 9 and the heart-shaped air deflector 8 can allow the hot air to enter the inner tank of the dishwasher from the air supply device, and can prevent water splashes from entering the air supply device from the air supply port 10; meanwhile, in the utility model When the machine stops working, even if the hot and humid air from the dishwasher liner enters the air duct, since the density of the hot air is lower than that of the cold air, the hot and humid air cannot move downward from the upper end of the air duct to prevent the air from overflowing, and the heat preservation effect is good. In this way, if the dishwasher is washed at high temperature, there is no need to turn on the heating element 3, and the residual temperature of the inner tank of the dishwasher after high-temperature washing is directly used to start the fan, and the tableware and the four walls of the inner tank of the dishwasher can be cleaned in a short time. blow dry. Very energy saving.

The utility model can also be provided with a program controller to control whether the heating elements work or not and the heating time according to the actual working conditions and usage requirements of the dishwasher.
