[0037] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.
[0038] like Figure 1 As shown, the drying tunnel assembly 100 of the embodiment of the utility model includes a drying tunnel 1, an impeller 2, a heating element 3 and a spray assembly 4.
[0039] The drying tunnel 1 can be generally in the shape of a flat tube and can extend in the left and right directions. The material of the drying tunnel 1 can be metal, specifically stainless steel, aluminum alloy, etc., so that the structural strength of the drying tunnel 1 is high, and the drying tunnel 1 has the characteristics of corrosion resistance and high temperature resistance, which fully meets the needs of hot air supply and the like.
[0040] The impeller 2 and the heating element 3 are both installed in the drying tunnel 1. Figure 1 As shown, the impeller 2 can be rotatably mounted on the right end of the drying tunnel 1, and the rotating shaft of the impeller 2 can be connected to the motor, and the impeller 2 can be driven to rotate in the drying tunnel 1 by the motor, thereby meeting the use needs of conveying airflow. The heating element 3 can be a heating tube, and the heating element 3 can be fixed in the drying tunnel 1 and can be located in the left half of the drying tunnel 1. When current is passed through the heating element 3, the heating element 3 can generate heat, thereby achieving heating of the airflow in the drying tunnel 1, meeting the use needs of supplying hot airflow.
[0041] At least part of the spray assembly 4 is arranged in the drying tunnel 1 , and the impeller 2 and the heating element 3 are located within the spray range of the spray assembly 4 so that the spray assembly 4 can rinse and remove impurities attached to the impeller 2 and / or the heating element 3 .
[0042] For example, Figure 1 As shown, the spray assembly 4 can be assembled on the side wall of the drying tunnel 1. The spray assembly 4 can include structures such as a spray head and a spray pipe. When in use, a spray medium can be introduced into the spray assembly 4. The spray medium can be a liquid such as water. The spray medium can be directly sprayed on the impeller 2 and the heating element 3, thereby achieving the flushing of impurities such as lint attached to the impeller 2 and the heating element 3.
[0043] It should be noted that the overall shape of the spray medium sprayed by the spray assembly 4 can be fan-shaped, and the fan-shaped area formed by the spray medium is the spray range. The impeller 2 and the heating element 3 are both located within the spray range of the spray medium, so that the spray medium sprayed by the spray assembly 4 can spray and rinse the impeller 2 and the heating element 3 at the same time. In the process of cleaning the impeller 2, the impeller 2 can be cleaned by combining the rotation of the impeller 2 itself.
[0044] The drying tunnel assembly 100 of the embodiment of the utility model is provided with a spray component 4 in the drying tunnel 1. The impeller 2 and the heating element 3 are both located within the spray range of the spray component 4. The impeller 2 and the heating element 3 can be regularly flushed by the spray component 4, thereby removing impurities attached to the impeller 2 and the heating element 3.
[0045] Removing impurities attached to the impeller 2 can prevent the accumulated impurities on the impeller 2 from affecting the working performance of the fan, and also prevent the fan from being blocked due to a large number of impurities adsorbed on the fan, thereby ensuring the drying performance and the drying efficiency of the clothes.
[0046] Removing impurities attached to the heating element 3 can prevent the heating element 3 from dry-burning the impurities, thereby avoiding the dry-burning causing machine odor and major safety hazards, thereby improving the safety of the operation process.
[0047] In some embodiments, the spray assembly 4 includes a main pipe 41 and a plurality of branch pipe groups 42, at least part of the main pipe 41 is located in the drying tunnel 1, and the plurality of branch pipe groups 42 are arranged at intervals along the main pipe 41 and are all located in the drying tunnel 1, each branch pipe group 42 includes a plurality of branch pipes 43 arranged at intervals along the circumference of the main pipe 41, and each branch pipe 43 is provided with a spray outlet 434 for spraying the spray medium.
[0048] For example, Figure 2 As shown, the main pipe 41 may be in a circular tube shape, the main pipe 41 may be fixed on the side wall of the drying tunnel 1, a portion of the main pipe 41 may protrude from the inner surface of the drying tunnel 1, and five branch pipe groups 42 may be provided. In some other embodiments, the branch pipe groups 42 may also be provided in numbers of three, four, six, seven, eight, etc. Multiple branch pipe groups 42 may be fixed on the main pipe 41 and may be arranged at equal intervals along the axial direction of the main pipe 41.
[0049] like Figure 2 As shown, each branch pipe group 42 may include five branch pipes 43. In some other embodiments, each branch pipe group 42 may also be provided with three, four, six, seven, or other number of branch pipes 43. The branch pipe 43 may also be in the shape of a circular tube, and the diameter of the branch pipe 43 may be smaller than the diameter of the main pipe 41. The five branch pipes 43 of each branch pipe group 42 may be arranged at equal intervals along the circumferential direction of the main pipe 41, that is, the multiple branch pipes 43 of each branch pipe group 42 are generally arranged in a fan shape. Each branch pipe 43 may be provided with at least one ejection port 434, and the ejection port 434 may be provided on the end face of each branch pipe 43, or on the pipe wall of the branch pipe 43.
[0050] When in use, the spray medium can be passed into the main pipe 41, and the spray medium will flow into each branch pipe 43 of the multiple branch pipe groups 42 at the same time, and then be sprayed out through the spray outlet 434 of each branch pipe 43, thereby meeting the need for spraying and flushing the impeller 2 and the heating element 3.
[0051] It should be noted that the above-mentioned multiple branch pipes 43 can achieve all-round cleaning of lint in the drying tunnel 1 without dead angles by being designed at different axial and circumferential positions and different spray bottle angles of the main pipe 41, and can cover the cleaning of lint inside the impeller 2, the heating tube and the upper and lower covers of the drying tunnel 1 where lint is easily accumulated, thereby fully meeting the cleaning operation requirements.
[0052] In some embodiments, the branch pipe 43 includes a necking section 431, which is used to reduce the flow cross section to increase the flow rate of the spray medium flowing to the spray outlet 434. Figure 3 As shown, the necking section 431 is a section of the branch pipe 43 with a smaller diameter. When the fluid flows in the pipe, the smaller the flow cross-section, the greater the flow velocity, and the larger the flow cross-section, the smaller the flow velocity. Therefore, the spraying medium will be accelerated in the necking section 431, which is conducive to the formation of high-energy bubbles at the spray outlet 434, which can improve the efficient cleaning of impurities such as lint.
[0053] In some embodiments, the branch pipe 43 includes a gradually expanding section 432, which is arranged between the necking section 431 and the nozzle 434. The radial dimension of the gradually expanding section 432 gradually increases along the direction from the necking section 431 to the nozzle 434, and the gradually expanding section 432 is used to increase the flow rate of the transonic spray medium flowing to the nozzle 434.
[0054] For example, Figure 3 As shown, the gradually expanding section 432 can be generally conical, and the gradually expanding section 432 can be connected to the right side of the necking section 431, and the radial dimension of the gradually expanding section 432 gradually increases from left to right. Since the transonic fluid no longer follows the principle of "the flow velocity is high at the small cross section and the flow velocity is low at the large cross section" when moving, but is just the opposite, that is, the larger the cross section, the faster the flow velocity, and at the necking section 431, the flow velocity of the spray medium can be accelerated to supersonic speed, thus, the transonic spray medium will continue to be accelerated at the gradually expanding section 432, so that the flow velocity of the spray medium flowing out of the ejection port 434 can be further increased and it is conducive to further forming high-energy bubbles, thereby further improving the efficient cleaning of impurities.
[0055] In some embodiments, the branch pipe 43 includes a tapered section 433 , which is located between the main pipe 41 and the necked section 431 , and a radial dimension of the tapered section 433 gradually decreases along a direction from the main pipe 41 to the necked section 431 .
[0056] For example, Figure 3 As shown, the tapered section 433 may also be generally conical, and the tapered section 433 may be connected to the left side of the necking section 431. The radial dimension of the tapered section 433 may gradually decrease from left to right, and the flow cross section at the tapered section 433 may gradually decrease, thereby gradually increasing the flow velocity of the spraying medium, which is beneficial to the overall structural stability.
[0057] In some embodiments, the upper limit value of the radial dimension of the tapered section 433 is smaller than the upper limit value of the radial dimension of the expanded section 432. Figure 3As shown, the tapered section 433 and the gradually expanding section 432 can both be roughly conical, the radial dimension of the left side of the tapered section 433 is the largest, the radial dimension of the right side of the gradually expanding section 432 is the largest, and the radial dimension of the left side of the tapered section 433 is smaller than the radial dimension of the right side of the gradually expanding section 432.
[0058] Thereby, the need for accelerated use of the spray medium can be fully met, which is conducive to the formation of high-energy bubbles and the enhancement of the cavitation effect of the spray bubbles, thereby improving the overall cleaning ability.
[0059] In some embodiments, the ejection port 434 is disposed at the end of the gradually expanding section 432 away from the necking section 431. Figure 3 As shown, when the branch pipe 43 is located on the right side of the main pipe 41, the spray outlet 434 can be located at the right end of the branch pipe 43. As a result, the plane where the spray outlet 434 is located can be roughly perpendicular to the flow direction of the spray medium. Compared with the curved design, the smoothness of the flow can be improved, blockage can be avoided, and the spraying effect can be improved.
[0060] In some embodiments, Figure 2 As shown, the multiple branch pipes 43 arranged at intervals along the circumference of the main pipe 41 in each branch pipe group 42 include a first branch pipe 44 and a second branch pipe 45 located on the end side, wherein the first branch pipe 44 can be located on the left side of the main pipe 41, the second branch pipe 45 can be located on the right side of the main pipe 41, and the remaining branch pipes 43 in each branch pipe group 42 can be located between the first branch pipe 44 and the second branch pipe 45.
[0061] The impeller 2 and the heater 3 are located within the angle region formed by the axis of the first branch pipe 44 and the axis of the second branch pipe 45, that is, the angle region formed by the axis of the first branch pipe 44 and the axis of the second branch pipe 45 can be regarded as the above-mentioned spray range, thereby meeting the operational needs of spraying and flushing impurities on the impeller 2 and the heater 3 at the same time.
[0062] In some embodiments, the extension direction of the main pipe 41 is consistent with the extension direction of the rotation axis of the impeller 2. Figure 1 As shown, the rotation axis of the impeller 2 can generally extend in the up-down direction, and the extension direction of the main pipe 41 can also be in the up-down direction. Since the impeller 2 and the heating element 3 have a certain thickness in the up-down direction, this arrangement of the main pipe 41 meets the needs of spraying and flushing the impeller 2 and the heating element 3 at different levels, and fully ensures the flushing and cleaning effect.
[0063] In some embodiments, the drying tunnel 1 includes a connected volute 11 and a channel 12, the impeller 2 is disposed in the volute 11, the heating element 3 is disposed in the channel 12, a volute tongue 13 is disposed at the connection between the volute 11 and the channel 12, and the spray assembly 4 and the volute tongue 13 are arranged opposite to each other.
[0064] For example, Figure 1 As shown, the drying tunnel 1 can be divided into two parts according to different shapes and different assembly parts, namely, the volute 11 and the channel 12, wherein the volute 11 can be generally in the shape of an edge column, and the channel 12 can be generally in the shape of a flat tube, and the channel 12 can be integrally formed on the left side of the volute 11. The volute tongue 13 is provided at the connection between the volute 11 and the channel 12, and the volute tongue 13 protrudes toward the inner side of the drying tunnel 1 and is used to prevent part of the gas from circulating in the volute 11.
[0065] like Figure 1 As shown, the volute tongue 13 can be arranged at the rear side of the drying tunnel 1, and the spray assembly 4 can be arranged at the front side of the drying tunnel 1. Thus, the spray assembly 4 and the volute tongue 13 are arranged at the same side of the drying tunnel 1, which easily causes a cleaning dead angle, and the cleaning effect is further ensured.
[0066] Optionally, the spray assembly 4 can be arranged at an oblique position of the volute tongue 13 , for example, the spray assembly 4 can be arranged on the left front side of the volute tongue 13 , and the spray assembly 4 is closer to the heating element 3 than the volute tongue 13 .
[0067] The drying system of the embodiment of the utility model is described below.
[0068] The drying system of the embodiment of the present utility model comprises a drying tunnel assembly 100 , and the drying tunnel assembly 100 may be the drying tunnel assembly 100 described in any of the above embodiments.
[0069] In some embodiments, Figure 4 As shown, the drying system includes a condenser 200 , which is connected to the inlet of the drying tunnel assembly 100 . The condenser 200 is used to remove moisture from the gas flowing into the drying tunnel assembly 100 , thereby meeting the need to transport dry gas to the drying tunnel assembly 100 .
[0070] The drying device of the embodiment of the utility model is described below.
[0071] The drying device of the embodiment of the utility model includes a drying system, and the drying system can be a drying system as described in any of the above embodiments. Figure 4 As shown, the drying device may be a dryer. In some other embodiments, the drying device may also be a device with a drying function such as a washing and drying machine. The drying device may include an inner barrel 300, the outlet of the drying tunnel assembly 100 may face the inner barrel 300, and the inlet of the condenser 200 may be connected to the inner barrel 300.
[0072] When in use, the air heated by the drying tunnel assembly 100 will enter the inner tub 300 and dry the clothes, that is, the clothes will exchange energy with the hot air, thereby achieving the effect of removing moisture. The humid hot air will then be discharged into the condenser 200, and the moisture will be removed by the condenser 200 to become dry air, and then continue to enter the drying tunnel 1 for heating under the action of the impeller 2, and finally enter the inner tub 300 again to dry the clothes, thereby realizing a cycle of the drying operation.
[0073] Although the above embodiments have been shown and described, it is to be understood that the above embodiments are illustrative and cannot be construed as limitations on the present invention.
