Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, and in particular to a dishwasher drying system. Background Technology

[0002] Dishwashers generally have a drying function, the main purpose of which is to quickly dry dishes after washing, preventing water droplets and bacterial growth. The drying function evaporates moisture from the surface of the dishes through various methods, ensuring that the dishes are free of watermarks and reducing water stains. To achieve the drying function, a drying device is usually installed on the outside of the dishwasher's inner tub. The drying device includes a fan and a PTC heating element. When the fan is working, it draws outside air into the inner tub. The outside air is heated as it passes through the PTC heating element, and the hot air dries the dishes after entering the inner tub. However, the installation of the fan and PTC heating element takes up a lot of space, making the drying device thicker and larger, thus increasing the overall size of the dishwasher.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this invention is to provide a dishwasher drying system that is simple in structure, occupies little space, has good drying effect, is easy to assemble and disassemble, and is highly practical, so as to overcome the shortcomings of the prior art.

[0005] A dishwasher drying system designed for this purpose is characterized by comprising an air inlet device disposed on the outside of the inner tub and a heating element disposed inside the inner tub. The air inlet device is provided with an air inlet and an air outlet that are interconnected. The air inlet is connected to the outside, and the air outlet is connected to the inside of the inner tub. When the air inlet device is working, outside air enters the inside of the inner tub in sequence through the air inlet and the air outlet.

[0006] It also includes a ventilation device located at the top of the inner liner, which has an air inlet and an air outlet that are interconnected. The air inlet is connected to the inside of the inner liner, and the air outlet is connected to the outside.

[0007] The air intake device includes a blower installed on the air inlet, with the air inlet end of the blower connected to the air inlet and the air outlet end of the blower connected to the air outlet.

[0008] The air intake device also includes an air purification component. A purification channel connecting to the air outlet is provided on one side of the air outlet, and the air purification component is installed on the purification channel.

[0009] The air intake device is equipped with an air intake channel, and the air outlet of the blower is connected to the air outlet through the air intake channel.

[0010] The heating element is located at the bottom of the inner liner, and the heating element is a dry-burning tube.

[0011] The ventilation device is equipped with an air outlet channel. The air inlet, air outlet channel and air outlet are connected in sequence and arranged from bottom to top.

[0012] The air purification components are plasma modules, negative ion modules, or ozone modules.

[0013] The air intake device also includes a first air duct shell and a second air duct shell that are connected to each other. The air inlet is located at the bottom of the first air duct shell, and the air outlet is located at the top of the second air duct shell. An air intake channel and a purification channel are formed between the first air duct shell and the second air duct shell.

[0014] The air intake device is flat and located at the bottom of the inner liner.

[0015] The dishwasher drying system of this utility model has an air inlet device on the outside of the inner tub and a heating element inside the inner tub. When the air inlet device is working, outside air enters the inner tub through the air inlet and air outlet in sequence, forming convection. The heating element heats the air inside the inner tub to form hot air, which can dry the tableware. Compared with the drying device of traditional dishwashers, the heating element is located inside the inner tub instead of inside the air inlet device (drying device), thereby reducing the thickness of the air inlet device, that is, reducing the volume of the air inlet device, and thus reducing the overall volume of the dishwasher.

[0029] See Figures 1-12 The drying system of this dishwasher includes an air inlet device a located on the outside of the inner tub 1 and a heating element 2 located inside the inner tub 1. The air inlet device a is provided with an air inlet 3 and an air outlet 4 that are connected to each other. The air inlet 3 is connected to the outside, and the air outlet 4 is connected to the inside of the inner tub 1. When the air inlet device a (blower 5) is working, outside air enters the inside of the inner tub 1 through the air inlet 3 and the air outlet 4 in sequence, forming convection. The heating element 2 continuously heats the air inside the inner tub 1 to form hot air, thereby drying the tableware.

[0030] It also includes a venting device b set on the top of the inner tank 1. The venting device b is provided with an air inlet 24 and an air outlet 25 that are connected to each other. The air inlet 24 is connected to the inside of the inner tank 1, and the air outlet 25 is connected to the outside. When the dishwasher is drying, hot steam will be generated inside the inner tank 1. The hot steam enters the air outlet channel 23 through the air inlet 24 and is then discharged to the outside through the air outlet 25, realizing the external circulation drying of the inner tank 1.

[0031] The air intake device a, heating component 2, and ventilation device b are arranged in a three-in-one layout.

[0032] The air intake device a includes a blower 5 installed on the air inlet 3. The air inlet end of the blower 5 is connected to the air inlet 3, and the air outlet end of the blower 5 is connected to the air outlet 4.

When the water level in the inner tank 1 is higher than the height of the overflow port 10, the water above the overflow port 10 will flow away through the overflow port 10. The height of the air outlet 4 and the air outlet 9 is higher than the height of the overflow port 10 to prevent the air entering the inner tank 1 through the air inlet device a from flowing into the water and affecting the air convection effect.

[0040] A base 18 is provided below the inner liner 1, and an overflow trough 19 is provided on the top of the base 18. An overflow outlet 20 is provided on the overflow trough 19. The overflow outlet 10, the overflow trough 19 and the overflow outlet 20 are connected in sequence. The overflow outlet 20 is connected to the inner cavity 21 of the base 18. Water that is higher than the overflow outlet 10 will flow through the overflow outlet 10 to the overflow trough 19. When the water in the overflow trough 19 is higher than a certain height, it will flow through the overflow outlet 20 into the inner cavity 21 of the base 18 and then flow into the water receiving tray in the inner cavity 21.

[0041] Air purification component 6 is a plasma module, a negative ion module, or an ozone module.
