Description

Technical Field

[0001] The invention belongs to the field of dishwashers, and in particular relates to an air inlet device for an inner tank of a dishwasher and a dishwasher. Background Art

[0002] At present, dishwasher drying has problems such as long drying process and incomplete drying, which greatly affects the user experience. There are two main drying modes: automatic door opening drying, which automatically opens the door after washing is completed, and increases air convection at the door through various means. There are disadvantages such as foreign objects easily contaminating tableware after opening the door, the door body hindering user movement, and condensation on the cabinet countertop due to rising hot air; residual temperature drying, after high-temperature boiling and washing, the surface moisture of the tableware is evaporated by its own high temperature. There are disadvantages such as long drying time, poor drying effect, and a lot of residual water inside the box.

[0003] The Chinese patent application number 202110397132.2 discloses a dishwasher drying device, including a washing tank, a drying mechanism body arranged on the outer surface of the side wall of the washing tank, and an air duct. The drying mechanism body is arranged on one side of the air duct and is connected to the air duct, and an ultraviolet lamp is arranged in the drying mechanism body; the washing tank is provided with an air outlet, the air outlet is connected to the air duct, and the air outlet is arranged in the washing tank near the bottom of the washing tank. The present invention arranges an ultraviolet lamp on the drying mechanism body for air circulation to ensure that the wind blown into the dishwasher has been sterilized and prevents external bacteria from entering the dishwasher. On the other hand, by setting the air duct into an inverted U-shaped structure and making the air outlet located at the lower position of the washing tank, the range of wind blowing can be effectively increased and the drying efficiency can be improved; at the same time, the outer baffle of the air outlet can blow the wind in different directions, effectively increasing the range of wind blowing, so that there is no dead angle in the drying area in the washing tank. Even so, it can be seen from the attached drawings that the wind entering and exiting the dishwasher through its air duct still has a fixed direction, divided into four directions: up, down, left and right, and the wind blown out is still direct current wind, which fails to increase the convection of wind in the dishwasher tank and cannot effectively shorten the drying time.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an air inlet device for the inner tank of a dishwasher and a dishwasher.

[0035] In a first aspect of the present invention, there is provided an air inlet device for a dishwasher inner tank, such as Figures 1 to 4 shown.

[0036] The dishwasher comprises an inner tank, an air duct and an air guide assembly, wherein an air inlet is arranged on the inner tank and communicates with an air outlet of the air duct. The air inlet of the inner tank of the dishwasher is connected to the air outlet of the air duct, and an air guide assembly is arranged at the connection.

[0037] Furthermore, the air guide assembly includes a fixing member 3 and an impeller 2. The impeller 2 is rotatably mounted on the fixing member 3. The fixing member 3 is installed in cooperation with the air duct to connect the air duct with the inner tank.

[0038] Advantageously, an air guide component is provided at the connection between the air inlet of the inner tank and the air outlet of the air duct. The air guide component is installed at the connection between the air inlet of the inner tank of the dishwasher and the air outlet of the air duct, which is beneficial to converting the direct current wind in the air duct into dispersed cyclone, which is input into the inner tank of the dishwasher to dry the tableware in the inner tank.

[0039] Furthermore, a portion of the fixing member 3 passes through the inner tank air inlet from the inner side of the inner tank and is connected to the air duct outlet outside the inner tank, so that the inner tank air inlet is clamped between another portion of the fixing member 3 located on the inner side of the inner tank and the air duct outlet.

[0040] It should be noted that the fixing member 3 in this embodiment has two functions: first, to connect the inner tank of the dishwasher and the air duct; second, to install the air guide assembly at the air inlet of the inner tank of the dishwasher.

[0041] Furthermore, the fixing member 3 includes an end cover 31 and a connecting portion 33. As long as the outer diameter of the other end of the connecting portion 33 is smaller than the inner diameter of the air inlet of the inner tank, it is used to pass through the air inlet of the inner tank and connect with the air outlet of the air duct. The end cover 31 and the connecting portion 33 have a channel for air to pass through.

[0042] Specifically, the end cover 31 is an annular cover body, and the connecting portion 33 is a sleeve structure arranged on the inner ring of the end cover 31, and both are provided with passages for air to pass through, so that the hot air in the air duct can enter the inner tank of the dishwasher through the end cover 31 and the connecting portion 33.

[0043] Furthermore, an outer circumference of the connection portion 33 is provided with an external thread, and the air outlet of the air duct is provided with an internal thread, and the connection portion 33 is threadedly connected to the air outlet of the air duct.

[0044] Preferably, the fixing member 3 is of an integrated structure, which can effectively prevent the fixing member 3 from being separated or deformed during use.

[0045] Specifically, an external thread is provided on the outer periphery of the connecting portion 33 of the fixing member 3, and an internal thread is provided on the inner side of the air duct outlet. The external thread provided on the connecting portion 33 matches the internal thread provided on the inner side of the air duct outlet, thereby realizing the fastening installation of the fixing member 3 and the air duct outlet.

[0046] Specifically, during installation, the external thread provided on the connection portion 33 of the fixing member 3 is aligned with the internal thread provided on the inner side of the air duct outlet, and the two are fixedly installed according to the rotation direction of the thread, so as to realize the installation of the air guide assembly. At the same time, the fixing member 3 realizes the connection between the air inlet of the dishwasher inner tank and the air duct outlet.

[0047] Furthermore, the wind guide assembly also includes a rotating shaft 1 , which is connected to a fixing member 3 and is used for pivotally supporting the impeller 2 .

[0048] Preferably, the rotating shaft 1 and the fixing member 3 are detachably connected.

[0049] Furthermore, the rotating shaft 1 and the impeller 2 are rotatably connected, which can ensure that the impeller 2 rotates around the rotating shaft 1.

[0050] Specifically, the rotating shaft 1 passes through the center of the impeller 2, and the two are rotatably connected. Driven by the air outlet of the air duct, the impeller 2 rotates axially around the rotating shaft 1.

[0051] Furthermore, the impeller 2 of the air guide assembly includes a blade 21 and a center seat 22. One end of the blade 21 is mounted on the center seat 22, and the other end extends outward, and the blade 21 rotates together with the center seat 22. The blade 21 is mounted on the center seat 22 at a certain angle, and rotates around the rotation axis 1 together with the center seat 22 under the drive of the air outlet of the air duct.

[0052] Furthermore, the central seat 22 is provided with a mounting hole for the rotating shaft 1, which is used for being clamped on the rotating shaft 1 and realizing the rotation of the air guide assembly.

[0053] Specifically, the blades 21 are installed on the central seat 22 at a certain angle, the angle range is 10° to 45°, and as the angle increases, the wind force and air volume passing through the wind guide assembly also increase, which can reduce the loss of air volume.

[0054] Furthermore, a rotating shaft 1 mounting hole is provided on the central seat 22 , and the rotating shaft 1 passes through the mounting hole and the rotating seat 321 of the supporting portion 32 of the fixing member 3 , and is clamped in the rotating seat 321 of the fixing member 3 , thereby achieving a fixed connection with the fixing member 3 .

[0055] Furthermore, a limiting protrusion 11 is provided on the top of the rotating shaft 1 to prevent the impeller 2 from deviating from the axial direction or separating from the rotating shaft 1 during the rotation process.

[0056] Furthermore, the fixing member 3 further includes a supporting portion, which is disposed in the channel of the connecting portion 33 and is used for supporting and connecting the rotating shaft 1 .

[0057] Furthermore, the supporting portion 32 includes a rotating seat 321 and connecting ribs 322. The rotating seat 321 is provided with a mounting hole, and the rotating shaft 1 is inserted into the mounting hole. There are at least two connecting ribs 322, which are arranged on the outer periphery of the rotating shaft 1, one end of which is connected to the rotating seat 321, and the other end is connected to the connecting portion 33. A gap is formed between the connecting ribs 322 for air to pass through.

[0058] Furthermore, a groove 12 is provided on the rotating shaft 1, and a protrusion 3211 is provided on the inner periphery of the rotating seat 321 of the connecting portion 33. The groove 12 cooperates with the protrusion 3211 to realize the limited installation of the rotating shaft 1 and the fixing member 3 to ensure that the rotating shaft 1 does not rotate with the impeller 2.

[0059] More specifically, the rotating shaft 1 is passed through the rotating shaft 1 mounting hole provided on the central seat 22 of the impeller 2, and then passed through the rotating seat 321 of the connecting portion 33 of the fixing member 3, and the rotating shaft 1 is engaged with the protrusion 3211 provided on the rotating seat 321 of the connecting portion 33 of the fixing member 3 through the provided groove 12, so as to achieve the fixed connection of the rotating shaft 1. The external thread provided on the connecting portion 33 of the fixing member 3 is aligned with the internal thread provided on the air outlet of the air duct, and then the fixing member 3 is installed at the air outlet of the air duct of the dishwasher according to the direction of the thread rotation, so as to achieve the overall installation of the air guide assembly and the connection between the air inlet of the inner tank of the dishwasher and the air outlet of the air duct.

[0060] It should be noted that, after installation, the impeller 2 of the air guide assembly is close to one side of the air inlet of the inner tank of the dishwasher.

[0061] Furthermore, a sealing portion is provided on the outer peripheral wall of the air outlet of the air duct, and the sealing portion abuts against the outer wall of the inner tank of the dishwasher.

[0062] Furthermore, the sealing portion is provided with a mounting groove, the groove opening of which faces the outer wall of the inner tank, and a sealing ring is provided in the mounting groove for achieving sealing at the connection between the air inlet of the inner tank and the air outlet of the air duct.

[0063] Specifically, the air inlet of the dishwasher inner tank and the air outlet of the air duct are connected by threads through the fixing member 3, and the air guide assembly is installed at the connection between the air inlet of the dishwasher inner tank and the air outlet of the air duct. After the connection is completed, the sealing part on the outside of the dishwasher cooperates with the sealing ring set in the groove to seal the connection between the air inlet of the dishwasher inner tank and the air outlet of the air duct to prevent leakage of hot air.

[0064] Another aspect of the present invention provides a dishwasher using the dishwasher inner tank air inlet device.

[0065] After the dishwasher completes washing and enters the drying stage, the dishwasher's fan extracts dry air from the air, the air is heated by the heating module, and then flows into the air duct. The dishwasher's air duct is provided with multiple air outlets, so the airflow is divided into multiple strands in the air duct and injected into the inner tank of the dishwasher. It should be noted that in order to match the multiple air outlets of the air duct, the inner tank of the dishwasher is provided with multiple air inlets.

[0066] Before the hot air in the air duct enters the inner tank of the dishwasher, it drives the impeller 2 of the air guide assembly to rotate. The air guide assembly converts the direct air in the air duct into a cyclone through the rotation of the impeller 2 and blows it into the inner tank of the dishwasher, filling the entire inner tank and drying the dishes in the inner tank. During the drying process, the excess air flows out from the inner tank air outlet and enters the air.

[0067] The airflow passes through the air guide component and enters the inner tank of the dishwasher, changing from the original direct airflow to diffuse airflow, which can quickly fill the entire cabinet, greatly improving the convection inside the cabinet. While solving the drying dead corners, it also reduces the drying time and improves the drying effect of the dishwasher.
