Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0050] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0051] like Figure 1-2 As shown, this embodiment of the invention provides a washing tub for use in a washing machine. The washing tub is detachably installed inside the washing machine and includes an outer tub 1, an inner tub 2, and an isolation layer. The inner tub 2 is installed inside the outer tub 1. The isolation layer includes a first isolation layer 3, a second isolation layer 4, and a third isolation layer 5. The first isolation layer 3, the second isolation layer 4, and the third isolation layer 5 are all provided with multiple layers. The first isolation layer 3 is detachably fitted onto the inner wall of the inner tub 2, the second isolation layer 4 is detachably fitted onto the outer wall of the inner tub 2, and the third isolation layer 5 is detachably fitted onto the inner wall of the outer tub 1.

[0052] In this embodiment of the invention, the washing tub is detachably installed inside the washing machine, allowing for tub replacement and facilitating cleaning, maintenance, and the addition of new insulating layers. The washing tub is configured as a double-layer structure comprising an outer tub 1 and an inner tub 2. During the washing process, the outer tub 1 is fixed inside the washing machine and does not rotate. The bottom of the inner tub 2 is connected to the washing machine's rotating shaft (not shown) and rotates with the shaft. The clothes and the washing water will come into contact with the inner wall of the inner tub 2, the outer wall of the inner tub 2, and the inner wall of the outer tub 1. To prevent bacteria and dirt from the clothes from remaining on the washing tub, insulating layers are used to cover the inner wall of the inner tub 2, the outer wall of the inner tub 2, and the inner wall of the outer tub 1, respectively. This avoids direct contact between the clothes and the washing tub, effectively preventing residual contamination from clothes washed before and after. Moreover, the insulating layers are multi-layered and removable. Compared with existing methods that use multiple washing tubs to prevent bacteria and dirt from remaining on the washing tub, using multiple insulating layers eliminates the need for frequent tub replacements, and the operation of removing one insulating layer each time is simple, efficient, and convenient.

[0053] Specifically, the isolation layer is a thin film, with multiple layers of film respectively set on the inner wall of the inner tub 2, the outer wall of the inner tub 2, and the inner wall of the outer tub 1. Each time a wash is performed, one layer of film is removed. The film is low in cost and, being set on the inner wall of the washing tub, has almost no adverse effect on the washing machine's operation.

[0054] More specifically, the first isolation layer 3, the second isolation layer 4, and the third isolation layer 5 can be an integrated isolation layer, i.e., an integrated film, which can prevent water from affecting the connection between the multiple isolation layers through the gaps between the first isolation layer 3, the second isolation layer 4, and the third isolation layer 5 during the washing process. Moreover, the integrated isolation layer only needs to be removed once when removing the isolation layer, which is more convenient compared to the first isolation layer 3, the second isolation layer 4, and the third isolation layer 5 needing to be removed three times.

[0055] In some embodiments, there is a gap between the outer tub 1 and the inner tub 2. The outer tub 1 and the inner tub 2 respectively have an outer tub receiving cavity 11 and an inner tub receiving cavity 21. The inner tub 2 is disposed in the outer tub receiving cavity 11. The surface of the inner tub 2 is provided with a plurality of dewatering holes (not shown) that communicate with the inner tub receiving cavity 21. The bottom of the outer tub 1 is provided with a drain outlet (not shown) that communicates with the outside.

[0056] In this embodiment, when washing clothes, the clothes are placed in the inner tub 2. The gap between the outer tub 1 and the inner tub 2 provides extra space for the clothes, which helps to accommodate the movement of the clothes during tumbling and dehydration, thereby improving the dehydration effect. The surface of the inner tub 2 is provided with multiple dehydration holes that connect the gaps to the inner tub cavity 21. The water in the clothes can be discharged from the inner tub cavity 21 to the gap in the outer tub cavity 11 through the dehydration holes, thereby achieving the separation of clothes and water, improving the dehydration effect, and reducing the time required for clothes to dry. The drain outlet is used to discharge water from the washing tub.

[0057] Specifically, the dehydration hole is located on the side wall of the inner tub 2.

[0058] In this embodiment, the dehydration hole is located on the side wall of the inner tub 2, which can increase the centrifugal force and the rotation speed of the water flow during dehydration, thereby improving the dehydration effect. By not setting the dehydration hole at the bottom of the inner tub 2, it is possible to avoid the bottom dehydration hole from generating a certain adsorption force on the clothes, which would affect the dehydration effect of the clothes.

[0059] In some embodiments, the first isolation layer 3 and the second isolation layer 4 are respectively provided with a first connecting hole (not shown) and a second connecting hole (not shown) corresponding to the dewatering holes, and the third isolation layer 5 is provided with a third connecting hole (not shown) corresponding to the drain outlet.

[0060] In this embodiment, a first connecting hole and a second connecting hole are respectively opened on the isolation layer corresponding to the dehydration hole to avoid the isolation layer affecting the dehydration effect of the inner tub 2, and to reduce the impact of water flow on the connection between the outermost isolation layer and its adjacent isolation layer; the third isolation layer 5 is provided with a third connecting hole corresponding to the drain outlet to provide a channel for the washing tub to drain.

[0061] In some embodiments, the multiple first isolation layers 3 are detachably connected by a first connector (not shown), the multiple second isolation layers 4 are detachably connected by a second connector (not shown), and the multiple third isolation layers 5 are detachably connected by a third connector (not shown).

[0062] In this embodiment, the multiple first isolation layers 3 are detachably connected to the inner wall of the inner tub 2 via first connectors, the multiple second isolation layers 4 are detachably connected to the outer wall of the inner tub 2 via second connectors, and the multiple third isolation layers 5 are detachably connected to the inner wall of the outer tub via third connectors. The first, second, and third connectors serve to connect and support the layers. Specifically, if the isolation layers are made of a relatively strong material, the first, second, and third connectors can be used to connect the multiple isolation layers together using screws; if the isolation layers are made of a relatively soft material, the first, second, and third connectors can be used to bond the multiple isolation layers together using adhesive.

[0063] like Figure 5-6 As shown, this embodiment of the invention also provides a washing tub control device 100, applied to the washing tub described above, comprising:

[0064] The detection unit 101 is used to detect the remaining number of layers in the first isolation layer, the second isolation layer and the third isolation layer when a washing start command is received, and to display the corresponding remaining number of layers respectively;

[0065] The first judgment unit 102 is used to determine whether there is at least one of the remaining layers with a value of zero.

[0066] The washing unit 103 is configured to, if the condition is true, not start washing and issue an instruction to replace the washing tub; otherwise, start washing.

[0067] The second judgment unit 104 is used to determine whether an instruction to remove the isolation layer has been received after the washing is completed;

[0068] The cleaning unit 105 is used to clean one or more of the first isolation layer, the second isolation layer and the third isolation layer if the condition is met; the cleaning method is to clean the outermost layer of the corresponding isolation layer.

[0069] In this embodiment of the invention, the detection unit 101, in conjunction with the first judgment unit 102, can intelligently detect the remaining number of layers and display the remaining number of layers corresponding to the first isolation layer 3, the second isolation layer 4, and the third isolation layer 5 respectively. If at least one isolation layer has zero remaining layers, the washing unit 103 issues an instruction to replace the washing tub, promptly reminding the user to replace the washing tub. This avoids bacterial and dirt residue remaining in the washing tub due to insufficient remaining layers of any of the first isolation layer 3, the second isolation layer 4, and the third isolation layer 5. If no isolation layer has zero remaining layers, the washing process is started. After the washing process is completed, the second judgment unit 104 determines whether an instruction to remove the isolation layers has been received. If an instruction to remove the isolation layers is received, the removal unit 105 can selectively remove one or more of the first isolation layer 3, the second isolation layer 4, and the third isolation layer 5. This eliminates the need for frequent replacement of the washing tub, and the operation of removing only the outermost isolation layer each time is simple, efficient, and convenient.

[0070] Specifically, after the clearing unit 105 clears one or more of the first isolation layer 3, the second isolation layer 4, and the third isolation layer 5, the detection unit 101 displays that the number of remaining isolation layers has decreased by one, and no further detection is required.

[0071] Specifically, the detection unit 101 detects the thickness of the multiple isolation layers to determine the number of remaining isolation layers. Based on the thickness of the remaining isolation layers and the thickness of each isolation layer, the number of remaining layers corresponding to the first isolation layer 3, the second isolation layer 4, and the third isolation layer 5 can be accurately determined.

[0072] Specifically, the washing unit 103 includes a replacement indicator light (not shown). If at least one isolation layer has zero remaining layers, the washing unit 103 issues a command to replace the washing tub, and the indicator light corresponding to the replacement command lights up or flashes.

[0073] Specifically, the clearing unit 105 includes a clearing button (not shown). The instruction to clear the isolation layer is controlled by the clearing button. When the user presses the clearing button, the clearing button sends the instruction to clear the isolation layer to the second judgment unit 104.

[0074] Specifically, the cleaning unit 105 is equipped with an indicator light (not shown) corresponding to the first isolation layer 3, the second isolation layer 4, and the third isolation layer 5. After washing is completed, all three indicator lights illuminate. When cleaning the first isolation layer 3, the second isolation layer 4, and the third isolation layer 5 respectively, the indicator light corresponding to the isolation layer being cleaned changes or turns off. More specifically, after washing is completed, all three indicator lights illuminate red, and when any isolation layer is cleaned, its corresponding indicator light illuminates green.

[0075] More specifically, the cleaning unit 105 is equipped with a first cleaning button (not shown), a second cleaning button (not shown), and a third cleaning button (not shown) for the first isolation layer 3, the second isolation layer 4, and the third isolation layer 5, respectively. The first cleaning button, the second cleaning button, and the third cleaning button control whether to clean the outermost isolation layer of the corresponding first isolation layer 3, second isolation layer 4, and third isolation layer 5. When not washing, the isolation layers can be selectively cleaned to improve the user experience.

[0076] In some embodiments, the washing tub control device 100 further includes:

[0077] The early warning unit 106 is used to obtain the remaining number of layers of the first isolation layer, the second isolation layer and the third isolation layer; compare the remaining number of layers of the first isolation layer, the second isolation layer and the third isolation layer with a predetermined early warning value; if at least one of the remaining number of layers is lower than the predetermined early warning value, an early warning is issued; if all the remaining number of layers is not lower than the predetermined early warning value, no early warning is issued.

[0078] In this embodiment, the warning unit 106 can issue a timely warning when the remaining number of layers is lower than a predetermined warning value, reminding the user to replace the washing tub, thus avoiding the problem of insufficient layers affecting the washing effect.

[0079] Specifically, the warning unit 106 can be opened before or after the washing process begins, and can detect the remaining number of isolation layers at any time. If the remaining number of at least one isolation layer is lower than the predetermined warning value, a warning will be issued.

[0080] Specifically, the predetermined warning value should be no less than 2 to avoid the remaining amount of isolation layer being too low to be sufficient for washing.

[0081] Specifically, the warning unit 106 includes three warning indicator lights (not shown) corresponding to three isolation layers. The three warning indicator lights are in the off state when there is no warning. When the number of remaining isolation layers is lower than the predetermined warning value, the warning indicator light corresponding to that isolation layer lights up.

[0082] like Figure 7 As shown, the early warning unit 106 includes:

[0083] The acquisition unit 601 is used to acquire the remaining number of layers of the first isolation layer, the second isolation layer, and the third isolation layer;

[0084] Comparison unit 602 is used to compare the remaining number of layers of the first isolation layer, the second isolation layer and the third isolation layer with a predetermined warning value, respectively;

[0085] The third judgment unit 603 is used to issue a warning if at least one of the remaining layers is lower than the predetermined warning value; and not to issue a warning if all the remaining layers are not lower than the predetermined warning value.

[0086] like Figure 8-9 As shown, this embodiment of the invention also provides a washing tub control method, applied to the washing tub described above, comprising steps S201~S206:

[0087] S201. When a command to start washing is received, the remaining number of layers in the first isolation layer, the second isolation layer, and the third isolation layer is detected and the corresponding remaining number of layers is displayed respectively.

[0088] S202. Determine whether there is at least one remaining layer with a value of zero;

[0089] S203. If so, do not start washing and issue an instruction to replace the washing tub;

[0090] S204. Otherwise, start the washing cycle;

[0091] S205. After washing is completed, determine whether an instruction to remove the isolation layer has been received;

[0092] S206. If so, one or more of the first isolation layer, the second isolation layer and the third isolation layer shall be cleared; the clearing method shall be to clear the outermost layer of the corresponding isolation layer.

[0093] In this embodiment of the invention, the remaining number of layers in the first isolation layer 3, the second isolation layer 4, and the third isolation layer 5 are detected and displayed respectively. When at least one of the remaining layers in the first isolation layer 3, the second isolation layer 4, and the third isolation layer 5 is zero, the washing cycle is stopped, and an instruction to replace the washing tub is issued. This timely reminder to replace the washing tub prevents bacteria and dirt from remaining in the washing tub due to insufficient remaining layers in any of the first isolation layer 3, the second isolation layer 4, and the third isolation layer 5. If no at least one isolation layer is zero remaining, the washing cycle is started. After the washing cycle is completed, it is determined whether an instruction to remove the isolation layers has been received. If an instruction is received, one or more of the first isolation layer 3, the second isolation layer 4, and the third isolation layer 5 can be selectively removed. This eliminates the need for frequent replacement of the washing tub, and the operation of removing one isolation layer each time is simple, efficient, and convenient. The device corresponding to this method, by covering the surface of the washing tub that contacts the washed clothes with multiple removable isolation layers, not only isolates the washed clothes from the washing tub, preventing bacteria and dirt from remaining in the washing tub, but also eliminates the need for frequent replacement of the washing tub, making the operation simple, efficient, and convenient.

[0094] In some embodiments, the washing tub control method further includes steps S301 to S304:

[0095] S301. Obtain the remaining number of layers of the first isolation layer, the second isolation layer, and the third isolation layer;

[0096] S302. Compare the remaining number of layers of the first isolation layer, the second isolation layer, and the third isolation layer with the predetermined warning value respectively;

[0097] S303. If at least one of the remaining layers is lower than the predetermined warning value, a warning is issued;

[0098] S304. If all remaining layers are not lower than the predetermined warning value, no warning will be issued.

[0099] In this embodiment, a warning is issued in a timely manner when the remaining number of layers is lower than a predetermined warning value, which can remind the user to replace the washing tub and avoid the problem of insufficient layers affecting the washing effect. The predetermined warning value can be set according to actual needs, which is highly flexible and has a wide range of applications.

[0100] like Figure 3-4 As shown, an embodiment of the present invention also provides a washing machine, including the washing tub as described above.

[0101] In this embodiment of the invention, the washing machine using the aforementioned washing tub has a detachable design inside the washing machine, allowing for tub replacement. This facilitates cleaning, maintenance, and the addition of new insulating layers. The washing tub is configured as a double-layer structure comprising an outer tub 1 and an inner tub 2. During the washing process, the clothes and their washing water come into contact with the inner wall of the inner tub 2, the outer wall of the inner tub 2, and the inner wall of the outer tub 1. To prevent bacteria and dirt from remaining on the washing tub, insulating layers are used to cover the inner wall of the inner tub 2, the outer wall of the inner tub 2, and the inner wall of the outer tub 1, respectively. This prevents direct contact between the clothes and the washing tub, effectively preventing residual contamination from clothes washed before and after. Furthermore, the insulating layers are multi-layered and removable. Compared to existing methods that use multiple washing tubs to prevent bacteria and dirt from remaining on the washing tub, using multiple insulating layers eliminates the need for frequent tub replacements, and the operation of removing one insulating layer each time is simple, efficient, and convenient.

[0102] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
