Description

Technical Field

[0001] The utility model relates to the field of dishwashers, in particular to an air guide device for a dishwasher. Background Art

[0002] Dishwashers are commonly used household appliances, and the interior of the dishwasher is relatively humid. In order to improve the drying effect, it is necessary to open a vent on the inner tank of the dishwasher so that the inner tank cavity is connected to the outside through a pipe of a certain length to discharge the humid air. The existing technology generally adds an independent air guide component to the outside of the inner tank of the dishwasher to conduct the internal humid air to the outside of the machine. However, the problem with the existing technology is that due to the limited space of the dishwasher, a ventilation duct must be installed between the outer shell and the inner tank of the dishwasher. In order to achieve better ventilation effect of the ventilation duct, the space between the outer shell and the inner tank must be increased. In this way, under the same size of the dishwasher, the inner tank space will be reduced, and the space utilization rate will be very low. In addition, since the ventilation duct is a dedicated general pipeline component, this structure has many parts, a complex structure, and a high cost. Utility Model Content

[0003] The utility model discloses an air guide device for a dishwasher, which is used to solve the deficiencies of the prior art.

[0004] In order to solve the above problems, the technical solution of the present invention is:

A vent is provided on the rear surface. The front of the U-shaped groove is provided with an air inlet connected to the inner tank cavity, and the rear of the U-shaped groove is provided with an air outlet connected to the outside of the dishwasher. The vent is connected to the air outlet, and a ventilation channel connecting the inner tank cavity and the outside of the dishwasher is formed between the inner tank shell and the air guide duct.

[0006] The air duct is installed at the upper corner of the outer upper part of the inner shell, and the U-shaped groove is located at this corner. The air duct is a cavity component with one open side composed of the outer surface, inner surface, top surface, front surface and rear surface.

DETAILED DESCRIPTION

[0021] The specific implementation of the present invention is further described in detail below with reference to the accompanying drawings.

[0022] See attached Figure 1-8 The utility model includes an inner tank shell 1 and an air duct 2. The inner tank shell 1 has an inner tank cavity 11. The air duct 2 is installed on the outside of the inner tank shell 1, and a U-shaped groove 14 is provided on the outside of the inner tank shell 1. The air duct 1 is a cavity component with an opening on one side. The front of the air duct 1 has a front surface 25 and the rear has a rear surface 26. A vent 261 is provided on the rear surface 26. The front of the U-shaped groove 14 is provided with an air inlet 15 connected to the inner tank cavity 11, and the rear of the U-shaped groove 14 is provided with an air outlet 16 connected to the outside of the dishwasher. The vent 261 is connected to the air outlet 16. A ventilation channel 3 connecting the inner tank cavity 11 and the outside of the dishwasher is formed between the inner tank shell 1 and the air duct 2.

[0023] The air duct 2 is installed at the upper corner of the outer upper part of the inner shell 1, and the U-shaped groove 14 is located at this corner. The air duct 1 is composed of an outer surface 21, an inner surface 22, a top surface 24, a front surface 25 and a rear surface 26 to form a cavity component with one side open.

[0024] A plurality of outer blocking ribs 23 are provided inside the cavity of the air duct 1, and a plurality of inner blocking ribs 13 are provided in the U-shaped groove 14 at the upper corner of the inner shell 1. The outer blocking ribs 23 and the inner blocking ribs 13 are arranged in an interlaced manner in the ventilation channel 3, and the ventilated gas flows in an S-shaped direction under the action of the outer blocking ribs 23 and the inner blocking ribs 13.

[0025] The height of the air inlet 15 is lower than that of the air outlet 16 . The bottom surface of the U-shaped groove 14 has a bottom inclined surface 17 , which extends obliquely downward from the air outlet 16 to the air inlet 15 .

[0026] The front surface 25 is provided with an outwardly extending mounting boss 1 251, the outer surface 21 and the inner surface 22 are provided with a buckle 27, the inner shell 1 is provided with a mounting boss 2 151 and an undercut 18, the mounting boss 1 251 of the air duct 2 is installed on the mounting boss 2 151 of the inner shell 1 by screws, and the buckle 27 is installed in conjunction with the undercut 18 to fix the inner shell 1 and the air duct 2.

[0027] The angle A between the inner blocking rib 24 and the air flow direction in the ventilation channel 3 is greater than 90°.

[0028] In actual application, the liner shell 1 has an liner cavity 11, and the air duct 2 is installed on the outside of the liner shell 1, and a U-shaped groove 14 is provided on the outside of the liner shell 1. The air duct 1 is a cavity component with an opening on one side, and the front of the air duct 1 has a front surface 25 and the rear has a rear surface 26. The rear surface 26 is provided with a vent 261, and the front of the U-shaped groove 14 is provided with an air inlet 15 connected to the liner cavity 11, and the rear of the U-shaped groove 14 is provided with an air outlet 16 connected to the outside of the dishwasher. The vent 261 is connected to the air outlet 16, and a ventilation channel 3 connecting the liner cavity 11 and the outside of the dishwasher is formed between the liner shell 1 and the air duct 2. The air duct 2 of this embodiment is installed at the upper top corner of the outer upper part of the liner shell 1, and the U-shaped groove 14 is located at this top corner. The air duct 1 consists of an outer surface 21, an inner surface 22, a top surface 24, a front surface 25 and a rear surface. The top corners of the inner tank shell 1 are generally arc-shaped, while the dishwasher shell is a right angle here. Therefore, the U-shaped groove 14 and the air duct 2 are set here, and the ventilation channel 3 can just utilize this rounded corner space, which not only increases the air path space of the ventilation channel 3, but also saves installation space, so that the inner tank shell 1 can make the inner tank cavity 11 space larger under the same size. At the same time, since the air duct 1 is a cavity component with one opening composed of the outer surface 21, the inner surface 22, the top surface 24, the front surface 25 and the rear surface 26, it is no longer a single independent functional component and needs to cooperate with the inner tank shell 1 to form a ventilation channel 3. In this way, one surface of the air duct 1 can be reduced, which not only saves materials and increases the ventilation space, but also reduces the space between the inner tank shell 1 and the dishwasher shell, so that the storage space of the inner tank cavity 11 is larger.

[0029] A plurality of outer blocking ribs 23 are provided inside the cavity of the air duct 1, and a plurality of inner blocking ribs 13 are provided in the U-shaped groove 14 at the upper corner of the inner shell 1. The outer blocking ribs 23 and the inner blocking ribs 13 are arranged in an interlaced manner in the ventilation channel 3, and the ventilated gas flows in an S-shaped direction under the action of the outer blocking ribs 23 and the inner blocking ribs 13. In this way, the air duct 1 can have a longer internal air flow path at the same length, and the humid air will continuously change the flow direction of the air during the circulation process, and the air will encounter the inner blocking ribs 13 and the outer blocking ribs 23 during the flow process, which will form condensation on the inner walls of the inner blocking ribs 13 and the outer blocking ribs 23, thereby minimizing the moisture in the discharged air. Therefore, the air duct 1 in this technical solution has a shorter product length and lower cost while achieving the same effect.

[0030] The height of the air inlet 15 is lower than that of the air outlet 16. The bottom surface of the U-shaped groove 14 has a bottom slope 17, which extends obliquely downward from the air outlet 16 to the air inlet 15. The condensed water formed after the air passes through the ventilation channel 3 flows back into the inner tank cavity 11 through the air inlet 15 through the action of the bottom slope 17.

[0031] In this embodiment, a mounting boss 1 251 extending outward is provided on the front surface 25, and buckles 27 are provided on the outer surface 21 and the inner surface 22. A mounting boss 2 151 and an undercut 18 are provided on the inner shell 1. The mounting boss 1 251 of the air duct 2 is installed on the mounting boss 2 151 of the inner shell 1 by screws, and the buckle 27 is installed in conjunction with the undercut 18 to fix the inner shell 1 and the air duct 2. Of course, the present invention is not limited to the buckle-type installation. The inner shell 1 and the air duct 2 can also be fixed by welding, screws, bonding and other fixed connection methods.

[0032] In this embodiment, the angle A between the inner blocking ribs 24 and the air flow direction in the ventilation channel 3 is greater than 90°. In this way, the air can encounter the blocking effect of the inner blocking ribs 24 during the circulation process, causing the air to flow back in the opposite direction to form resistance, thereby accelerating the condensation of moisture in the water and achieving a better condensation effect.
