Description

Technical Field

[0001] The present invention relates to the field of washing machines, and in particular to a multi-drum washing machine. Background Art

[0002] With the continuous improvement of people's living standards, people's demands for various aspects are becoming more and more demanding. For example, when washing clothes, people tend to sort them into different categories, and the categories are also increasing. For example, outerwear, underwear, socks, and clothes of different shades and colors must be washed separately. Using traditional washing machines to wash all the clothes with detailed categories is very time-consuming. Therefore, in addition to the original ordinary washing machines, many different washing machines have appeared on the market, such as small washing machines specifically for washing underwear, socks, and baby clothes, and washing machines that are two washing machines in one. Although this solves the problem of sorting clothes, it also adds many difficulties for users.

[0003] If you buy a small washing machine after purchasing an ordinary washing machine, it will take up more space, and it will be difficult to operate more than two washing machines at the same time.

[0004] The patent application number CN201920420606.9 in the prior art discloses a drying system and a washing and drying machine having the same, comprising a first drum and a second drum arranged in parallel, the drying system comprising an air duct assembly, the air duct assembly being provided with an air duct control device for conducting or cutting off the communication between the air duct assembly and the first drum and / or the second drum, so that the drying airflow can be sent to the first drum alone, to the second drum alone, or to the first drum and the second drum at the same time. Although the drying system of this patent can be shared by the two drums of a double-drum washing and drying machine, thereby increasing the drying capacity of a single washing and drying machine while reducing the manufacturing cost of the washing and drying machine and reducing the space occupied by the washing and drying machine, when the number of drums is greater than two, using a set of drying systems at the same time will result in a poor drying effect of the clothes and a longer drying time, thereby reducing the user experience.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0037] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0038] Example 1

[0039] like Figures 1 to 7 As shown, this embodiment proposes a multi-drum washing machine, such as Figure 1 and Figure 3As shown, the multi-drum washing machine 1 includes a first drum 13, a second drum 14 and an electric heating system 5. The electric heating system 5 can generate a hot air flow, and the hot air flow of the electric heating system 5 can be transported to the first drum 13 and / or the second drum 14 simultaneously or separately; the multi-drum washing machine 1 also includes a first drum 11 and a heat pump system 2. The heat pump system 2 can generate a hot air flow, and the hot air flow of the heat pump system 2 can be transported to the first drum 11.

[0040] In a multi-drum washing machine described in the present invention, the first drum 13 and the second drum 14 share the electric heating system 5 for drying, which reduces the manufacturing cost of the multi-drum washing machine and reduces the space occupied by the multi-drum washing machine; the first drum 11 uses the heat pump system 2 for drying, avoiding the use of one drying system for drying three drums at the same time, improving the drying effect of clothes, shortening the drying time, and improving the user experience.

[0041] Since the specific structures, specific assembly relationships and working principles of the relevant components of the heat pump system 2 and the electric heating system 5 are all existing technologies, they will not be described in detail here.

[0042] Specifically, an electric heating duct structure is arranged between the first cylinder 13, the second cylinder 14 and the electric heating system 5. The electric heating system 5 can generate a hot air flow, and the hot air flow of the electric heating system 5 can be simultaneously or separately transported to the first cylinder 13 and / or the second cylinder 14 through the electric heating duct structure.

[0043] Specifically, such as Figure 5 As shown, the electric heating air duct structure includes a third air duct 131 and a fourth air duct 141. The first tube 13 is connected to the electric heating system 5 through the third air duct 131; the second tube 14 is connected to the electric heating system 5 through the fourth air duct 141. The third air duct 131 is arranged between the first tube 13 and the electric heating system 5; the fourth air duct 141 is arranged between the second tube 14 and the electric heating system 5.

[0044] Specifically, such as Figure 5 As shown, the third air duct 131 and the fourth air duct 141 can be arranged to be connected together; the third air duct 131 and the fourth air duct 141 can also be arranged to be disconnected.

[0045] Preferably, in this embodiment, the third air duct 131 is not connected to the fourth air duct 141 .

[0046] The third air duct 131 and the fourth air duct 141 are not connected and are separate air inlet ducts, which can reduce the mutual transmission of bacteria.

[0047] Specifically, the position of the air inlet of the electrically heated air duct structure is not specifically limited. The air inlet of the electrically heated air duct structure is arranged on the door seal assembly, the barrel assembly or the barrel cover assembly of the first tube 13 and the second tube 14. The air inlet of the electrically heated air duct structure can be arranged on the door seal assembly of the first tube 13 and the second tube 14, the air inlet of the electrically heated air duct structure can also be arranged on the barrel assembly of the first tube 13 and the second tube 14, the air inlet of the electrically heated air duct structure can also be arranged on the barrel cover assembly of the first tube 13 and the second tube 14.

[0048] Preferably, in this embodiment, Figure 5 As shown, the air inlet of the electric heating air duct structure is arranged on the door sealing assembly of the first tube 13 and the second tube 14.

[0049] This arrangement is beneficial for simplifying the layout of the electric heating air duct structure and reducing the length of the third air duct 131 and the fourth air duct 141 .

[0050] Specifically, such as Figure 5 As shown, the air inlet of the electric heating duct structure includes a first air inlet 132 and a second air inlet 142. The first air inlet 132 is set on the first tube 13; the second air inlet 142 is set on the second tube 14. The first air inlet 132 and the second air inlet 142 are set on the door seal assembly.

[0051] More specifically, Figure 5 As shown, the first air inlet 132 is provided on the door seal of the first tube 13 ; the second air inlet 142 is provided on the door seal of the second tube 14 .

[0052] Specifically, such as Figure 7 and Figure 9 As shown, an exhaust duct structure is provided on the first tube 13 and the second tube 14 , and the exhaust duct structure includes a fifth duct 133 and a sixth duct 143 . The fifth duct 133 is provided on the first tube 13 , and the sixth duct 143 is provided on the second tube 14 .

[0053] Specifically, such as Figure 12 As shown, the exhaust duct structure is in communication with the outside. More specifically, the exhaust duct structure extends out of the housing and is in communication with the outside.

[0054] This arrangement facilitates the direct discharge of the hot and humid drying air discharged from the first cylinder 13 and the second cylinder 14 into the external environment. First, the exhaust duct structure is simple, the assembly efficiency is high, the drying effect is good, the manufacturing cost is low, and it is conducive to the application and promotion of the product; second, it prevents the hot and humid drying air from staying in the external space of the first cylinder 13 and the second cylinder 14 for a long time, causing the problem of bacterial growth; third, the hot and humid drying air can improve the temperature and humidity of the external environment, thereby improving the comfort of the user.

[0055] More specifically, Figure 12 As shown, the fifth air duct 133 and the sixth air duct 143 both extend out of the shell and communicate with the outside.

[0056] In this embodiment, if Figures 1 to 4 As shown, the first drum 11, the first barrel 13 and the second barrel 14 are all arranged inside the shell.

[0057] like Figures 1 to 4 As shown, the positions of the first drum 11 , the first tub 13 and the second tub 14 on the multi-drum washing machine 1 are not limited.

[0058] like Figure 1 and Figure 3 As shown, the first drum 13 and the second drum 14 are arranged side by side on the same horizontal line, and the first roller 11 is arranged below the first drum 13 and the second drum 14.

[0059] like Figure 2 As shown, the first drum 13 and the second drum 14 are arranged side by side on the same horizontal line, and the first roller 11 is arranged above the first drum 13 and the second drum 14.

[0060] like Figure 4 As shown, the first drum 13, the second drum 14 and the first roller 11 are arranged side by side in the vertical direction.

[0061] For the multi-drum washing machine, in addition to the first drum 13, the second drum 14 and the electric heating system 5, it also includes other related components such as the water inlet system and the drainage system. Since the specific structure and specific assembly relationship of the related components are all existing technologies, they will not be described here.

[0062] In a multi-drum washing machine described in the present invention, the first drum 13 and the second drum 14 share an electric heating system 5 for drying, thereby reducing the manufacturing cost of the multi-drum washing machine and reducing the space occupied by the multi-drum washing machine; the first drum 11 uses a heat pump system 2 for drying, thereby avoiding the three drums from using one drying system for drying at the same time, improving the drying effect of the clothes, shortening the drying time, and improving the user experience. The fifth air duct 133 and the sixth air duct 143 both extend out of the shell and communicate with the outside world, facilitating the direct discharge of the hot and humid drying air discharged from the first drum 13 and the second drum 14 into the external environment. First, the exhaust duct structure is simple, with high assembly efficiency, good drying effect, and low manufacturing cost, which is conducive to the application and promotion of the product; second, it avoids the hot and humid drying air from staying in the external space of the first drum 13 and the second drum 14 for a long time, which may cause the problem of bacterial growth; third, the hot and humid drying air can improve the temperature and humidity of the external environment, thereby improving the comfort of the user.

[0063] Example 2

[0064] Different from the first embodiment, in this embodiment, the third air duct 131 is connected to the fourth air duct 141 .

[0065] The third air duct 131 is connected to the fourth air duct 141, and the first drum 13 and the second drum 14 share an air inlet duct, which reduces the manufacturing cost of the electric heating duct structure and reduces the space occupied by the electric heating duct structure, thereby reducing the manufacturing cost of the multi-drum washing machine and reducing the volume of the multi-drum washing machine.

[0066] Example 3

[0067] Different from Example 1, in this embodiment, the third air duct 131 is connected to the fourth air duct 141, and an air duct switching device is provided in the electric heating air duct structure, and the air duct switching device is used to enable the heating air duct to be selectively connected to the third air duct 131 and / or the fourth air duct 141.

[0068] The third air duct 131 is connected to the fourth air duct 141, and the first drum 13 and the second drum 14 share a common air inlet duct. This reduces the manufacturing cost and space occupied by the electric heating duct structure, thereby reducing the manufacturing cost and size of the multi-drum washing machine. A duct switching device is provided in the electric heating duct structure to facilitate the adjustment of the hot air flow for drying to be delivered to the first drum 13 and / or the second drum 14 simultaneously or separately.

[0069] The air duct switching device includes a reversing motor and a baffle device. A baffle cam is installed on the driving output shaft of the reversing motor. The baffle cam is arranged at one end of the baffle device. The other end of the baffle device is rotatably installed in the electric heating air duct structure. The baffle cam is in contact with the baffle device; the reversing motor driving output shaft and the baffle cam rotate, thereby driving the baffle device to switch and move between the first position, the second position and the third position in the electric heating air duct structure.

[0070] The air duct switching device of the present invention reduces the torque of the reversing motor and improves the conduction stability of the air duct switching device.

[0071] Example 4

[0072] Different from Example 1, in this embodiment, specifically, Figure 6 As shown, the air inlet of the electric heating air duct structure is arranged on the cylinder assembly. Specifically, the first air inlet 132 and the second air inlet 142 are arranged on the cylinder assembly of the first cylinder 13 and the second cylinder 14.

[0073] More specifically, the first air inlet 132 is provided on the body of the first tube 13 ; the second air inlet 142 is provided on the body of the second tube 14 .

[0074] More specifically, Figure 6 As shown, the first air inlet 132 is provided at the bottom of the cylinder body of the first cylinder 13 ; the second air inlet 142 is provided at the bottom of the cylinder body of the second cylinder 14 .

[0075] This setting can ensure that the drying airflow can enter the first cylinder 13 and the second cylinder 14 from the bottom and flow out from the top, so that the flow path in the first cylinder 13 and the second cylinder 14 is as long as possible, thereby ensuring the drying effect and improving the user experience.

[0076] Example 5

[0077] Different from Example 1, in this embodiment, specifically, the air inlet of the electric heating air duct structure is arranged on the barrel cover assembly of the first tube 13 and the second tube 14. Specifically, the first air inlet 132 and the second air inlet 142 are arranged on the barrel cover assembly.

[0078] More specifically, the first air inlet 132 is provided on the cover of the first tube 13 ; the second air inlet 142 is provided on the cover of the second tube 14 .

[0079] This arrangement not only achieves the drying function but also achieves a neat and beautiful effect. This arrangement also ensures that the drying airflow can enter from the front barrel cover of the first barrel 13 and the second barrel 14 and flow out from the rear side, making the flow path in the first barrel 13 and the second barrel 14 as long as possible, thereby ensuring the drying effect and improving the user experience.

[0080] Example 6

[0081] Different from Example 1, in this embodiment, Figures 8-12 As shown, the multi-drum washing machine 1 also includes a second drum 12, and the first drum 11, the second drum 12, the first drum 13 and the second drum 14 are all arranged inside the shell. The hot air flow of the heat pump system 2 can be delivered to the first drum 11 and / or the second drum 12 simultaneously or separately.

[0082] It is convenient for users to carry out classified washing and improves the user experience.

[0083] The positions of the first drum 11 , the second drum 12 , the first tub 13 and the second tub 14 on the multi-drum washing machine 1 are not limited.

[0084] like Figure 8 and Figure 9 As shown, the first drum 13 and the second drum 14 are arranged side by side on the same horizontal line, the first roller 11 is arranged below the first drum 13 and the second drum 14, and the second roller 12 is arranged below the first roller 11. Figure 12 As shown, the capacity of the first drum 11 is smaller than that of the second drum 12, and the heat pump system 2 is arranged at the rear side of the first drum 11. This arrangement rationally utilizes the internal space of the multi-drum washing machine 1, reduces the occupied space and volume of the multi-drum washing machine 1, and reduces the cost of the multi-drum washing machine 1.

[0085] like Figure 10 As shown, the first drum 13 and the second drum 14 are arranged side by side on the same horizontal line, the first roller 11 is arranged above the first drum 13 and the second drum 14, and the second roller 12 is arranged below the first drum 13 and the second drum 14.

[0086] like Figure 11 As shown, the first drum 13 and the second drum 14 are arranged side by side on the same horizontal line, the first roller 11 is arranged above the first drum 13 and the second drum 14 , and the second roller 12 is arranged above the first roller 11 .

[0087] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the claims.
