Description

Technical Field

[0001] The utility model relates to the technical field of a washing, drying and drying machine, and more specifically, to an air duct structure of a washing, drying and drying machine. Background Art

[0002] A washing machine product that integrates the three functions of washing, dehydrating and drying is called a washing, drying and drying machine.

[0003] Currently, the most common drying duct structures for products with drying functions include top-in, bottom-out, door-in, side-out, and rear-in, side-out. However, directly implementing these three duct structures in a washer-dryer / dryer presents numerous issues, including complex duct structures, bulky size, offset center of gravity, hot door glass, uneven heating of fabrics, and poor drying performance and efficiency. Therefore, a new duct structure is urgently needed to promote the development of washer-dryers. Utility Model Content

[0004] In order to solve this problem in practical application, the present invention aims to provide an air duct structure for a washing, drying and drying machine. The specific solution is as follows:

[0005] A washer-dryer air duct structure includes an outer cylinder, an outer cylinder air inlet, an outer cylinder air outlet, and an inner drum. The inner drum is accommodated in the outer cylinder. The outer cylinder air inlet and the outer cylinder air outlet are provided on the upper portion of the outer cylinder, wherein the outer cylinder air inlet is a hot air inlet.

[0006] According to the different positional relationships between the outer cylinder air inlet and the outer cylinder air outlet on the left and right upper part of the outer cylinder, the inner drum rotates counterclockwise or clockwise to extend the flow of hot air in the inner drum.

[0007] Furthermore, it also includes an outer cylinder end plate, the outer cylinder end plate and the outer cylinder form a relatively closed cavity, and the inner roller is located in the cavity.

[0008] Furthermore, it also includes an outer cylinder front support and an outer cylinder rear support, and the outer cylinder front support and the outer cylinder rear support are arranged at the lower part of the outer cylinder.

[0009] Furthermore, the outer cylinder air inlet and the outer cylinder air outlet are staggered in front and back at the upper part of the outer cylinder.

[0010] Furthermore, the air inlet area of the outer cylinder air inlet is reduced by 30%-50%.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] The advantages of the present invention are that the air outlet and the air inlet of the outer cylinder are both on the upper part of the outer cylinder and are basically symmetrical, thus avoiding the deviation of the center of the machine. Its structure is simple and regular, which is conducive to the realization of the shock absorption technology of the whole machine, is convenient for connection with other components, and avoids the situation where the glass at the door is hot during drying. The present invention also stipulates that the inner drum rotates counterclockwise, and the air inlet and the air outlet of the outer cylinder are staggered front and back on the outer cylinder. The air inlet area of the outer cylinder is intentionally reduced by 30%-50%. All of these are to allow more hot air to enter through the mesh holes of the inner drum and come into contact with the clothes, so that the fabrics are heated more evenly, thereby improving the drying effect and drying efficiency.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] like Figure 1-2 As shown, an air duct structure of a washing, drying and drying machine includes an outer cylinder 1, an outer cylinder air inlet 2, an outer cylinder air outlet 3, an outer cylinder front support 4, an outer cylinder rear support 5, an inner drum 6, and an outer cylinder end plate 7. The outer cylinder 1 and the outer cylinder end plate 7 form a relatively closed cavity, which accommodates the inner drum 6, and the wall of the inner drum 6 has mesh holes; the outer cylinder air inlet 2 and the outer cylinder air outlet 3 are provided on the upper part of the outer cylinder 1, wherein the outer cylinder air inlet 2 is a hot air inlet to achieve drying; the outer cylinder front support 4 and the outer cylinder rear support 5 are provided on the lower part of the outer cylinder 1, which support the outer cylinder 1.

[0019] It should be noted that the inner drum 6 is installed inside the outer cylinder 1 through parts such as a bearing seat. This application does not involve improvements to the connecting parts, so they will not be described in detail here.

[0020] like Figure 3As shown, viewed from the front of the washer-dryer, the outer cylinder air inlet 2 and the outer cylinder air outlet 3 are respectively located on the upper left and upper right sides of the outer cylinder 1. At this time, the inner drum 6 rotates clockwise. Under the inertia of the rotation of the inner drum 6, the flow rate of the hot air in the inner drum 6 is short. The process at this time is set as the first process 8. The contact time between the hot air and the clothes is shortened, which slows down the drying efficiency of the clothes.

[0021] Based on this, in this application, according to the different left and right position relationships of the outer cylinder air inlet 2 and the outer cylinder air outlet 3 on the upper part of the outer cylinder 1, the inner drum 6 rotates counterclockwise or clockwise to extend the flow of hot air in the inner drum 6.

[0022] Specifically, in one possible embodiment, return to Figure 1 , viewed from the front of the washer-dryer, the outer cylinder air inlet 2 and the outer cylinder air outlet 3 are respectively located on the upper left and upper right side of the outer cylinder 1. At this time, the inner drum 6 rotates counterclockwise. In this way, the flow of hot air in the inner drum 6 will be prolonged under the inertia of the rotation of the inner drum 6. The process at this time is set as the second process 9. The second process 9 is obviously longer than the first process 8. The contact time between the hot air and the clothes is prolonged, which can effectively improve the drying efficiency.

[0023] In another possible embodiment (not shown in the figure), when viewed from the front of the washer-dryer, the outer cylinder air inlet 2 and the outer cylinder air outlet 3 are swapped at the left and right positions on the upper part of the outer cylinder 1. At this time, the inner drum 6 rotates clockwise. In this way, similarly, the inertia of the rotation of the inner drum 6 will extend the flow of hot air in the inner drum 6, and the contact time between the hot air and the clothes will be extended, which can effectively improve the drying efficiency.

[0024] In addition, the outer cylinder air inlet 2 and the outer cylinder air outlet 3 are staggered in front and back at the upper part of the outer cylinder 1, which effectively avoids the short circuit path of the hot air.

[0025] Compared with the air inlet of the existing conventional washer-dryer, the air inlet area of the outer cylinder air inlet 2 of the present application is reduced by 30%-50% to speed up the flow rate of hot air entering the outer cylinder 1, thereby allowing more hot air to enter through the mesh holes of the inner drum 6 and come into contact with the clothes, thereby improving the drying effect.

[0026] The specific implementation principle of this utility model is as follows: Figure 1 As shown, hot air enters through the outer cylinder air inlet 2, and the inner drum 6 rotates clockwise. At this time, under the inertia of the rotation of the inner drum 6, the flow of the hot air in the inner drum 6 is the second flow 9. The hot air contacts the clothes in the inner drum 6 to dry the clothes. Since the second flow 9 is extended, the drying efficiency of the clothes is improved.

[0027] Since the utility model stipulates that the rotation direction of the inner drum 6 is to extend the hot air process, and the outer cylinder air inlet 2 and the outer cylinder air outlet 3 are staggered front and back on the outer cylinder 1, the area of the outer cylinder air inlet 2 is reduced, which can allow more hot air to enter through the mesh holes of the inner drum 6 and come into contact with the clothes, thereby improving the drying efficiency.

[0028] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
