[0023] The embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.
[0024] The embodiments of the present application are described below in conjunction with Figure 1 and Figure 2 The multi-cylinder washing machine according to the embodiments of the present application is described.
[0025] The multi-cylinder washing machine according to the embodiments of the present application includes a shell 1, a first cylinder 2, a second cylinder 3, a first heater 4 and a second heater 5 arranged in the shell 1. The inner cylinder volume of the first cylinder 2 is a liters, the inner cylinder volume of the second cylinder 3 is b liters, the power of the first heater 4 is c watts, and the power of the second heater 5 is d watts. Wherein, a > b, 13 ≤ c / a ≤ 40, 100 ≤ d / b ≤ 200.
[0026] According to the multi-cylinder washing machine according to the embodiments of the present application, the ratio of the power of the first heater 4 to the inner cylinder volume of the first cylinder 2 is between 13 and 40, and the ratio of the power of the second heater 5 to the inner cylinder volume of the second cylinder 3 is between 100 and 200. This setting can satisfy the simultaneous operation of the first heater 4 and the second heater 5 without power overload, so as to ensure that the first cylinder 2 and the second cylinder 3 can simultaneously perform the working mode including the heating link, and under the above parameter range, the working time of the working mode including the heating link of the first cylinder 2 and the second cylinder 3 is close to or lower than the working time of the working mode including the heating link of the washing machine in the related art, thereby effectively improving the washing and protecting efficiency of the multi-cylinder washing machine while the user's use satisfaction is higher.
[0027] It should be noted that the working mode including the heating link of the present embodiment includes the heating washing mode and the drying mode, the first heater 4 can be applied to the heating washing mode and / or the drying mode of the first cylinder 2, and the second heater 5 can be applied to the heating washing mode and / or the drying mode of the second cylinder 3. When the first heater 4 and the second heater 5 are used for the heating washing mode, the working time of the heating washing mode can be set to be less than or equal to 150 min under the default setting, and the load surface temperature is maintained at 40-95℃. When the first heater 4 and the second heater 5 are used for the drying mode, the working time of the drying mode can be set to be less than or equal to 300 min under the default setting, and the load surface temperature is maintained at 40-95℃.
[0028] Optionally, the ratio of the power of the first heater 4 to the inner drum volume of the first drum 2 can be 13, 20, 30 and 40, and the ratio of the power of the second heater 5 to the inner drum volume of the second drum 3 can be 100, 130, 150, 170 and 200.
[0029] In some embodiments, the first heater 4 is a heater for heating the washing water in the first drum 2, or the first heater 4 is a heater of a corresponding drying system of the first drum 2. The second heater 5 is a heater for heating the washing water in the second drum 3, or the second heater 5 is a heater of a corresponding drying system of the second drum 3.
[0030] That is, the first drum 2 can have a heating washing mode or a drying mode, the second drum 3 can have a heating washing mode or a drying mode, and when the first drum 2 performs a heating washing operation or a drying operation, the second drum 3 can simultaneously perform a heating washing operation or a drying operation, so that the multi-drum washing machine has strong functionality and higher working flexibility.
[0031] Optionally, as shown in Figure 1 and Figure 2 When the first heater 4 is a heater for heating the washing water in the first drum 2, and the second heater 5 is a heater for heating the washing water in the second drum 3, the first heater 4 is located between the outer drum and the inner drum of the first drum 2, and the second heater 5 is located between the outer drum and the inner drum of the second drum 3.
[0032] In some embodiments, the first heater 4 includes an electric heating tube, and the second heater 5 includes a PTC heating tube.
[0033] The electric heating tube, that is, a heating tube with a resistance wire as a heating source, as a heater for heating the washing water with a larger volume in the inner drum of the first drum 2, has a lower power compared to the PTC heating tube, thereby better avoiding power overload when the first heater 4 and the second heater 5 work simultaneously, while meeting the requirement of heating the washing water to a set temperature within a set time.
[0034] In addition, by setting the second heater 5 as a PTC heating tube, the heating efficiency is higher, and thus the heating of the washing water in the inner drum of the second drum 3 can be achieved faster, and the washing and protection efficiency of the second drum 3 is higher.
[0035] Meanwhile, when the first heater 4 and the second heater 5 are applied to the drying mode of the first drum 2 and the second drum 3 respectively, on the basis of meeting the requirement of drying the clothes in the set volume within the set time, the power of the electric heating tube is lower than that of the PTC heating tube, thereby better avoiding power overload when the first heater 4 and the second heater 5 work simultaneously. In addition, by setting the second heater 5 as the PTC heating tube, the drying efficiency is higher, and the clothes in the inner drum of the second drum 3 can be dried faster.
[0036] Optionally, when the PTC heating tube works, the initial power is the maximum, which is d watts.
[0037] It should be noted that the first heater 4 can also be a PTC heating tube, and the second heating tube can also be an electric heating tube with a resistance wire as a heating source.
[0038] In some embodiments, as shown in Figure 1 and Figure 2 The number of the first heater 4 is two, and the number of the second heater 5 is two.
[0039] The two first heaters 4 are respectively used for the heating washing mode and the drying mode of the first drum 2, and the two second heaters 5 are respectively used for the heating washing mode and the drying mode of the second drum 3, so that when the first drum 2 is in any one of the heating washing operation and the drying operation, the second drum 3 can simultaneously be in any one of the heating washing operation and the drying operation, and the working flexibility of the multi-drum washing machine is higher, and the user's use satisfaction is higher.
[0040] Optionally, the power of the two first heaters 4 is the same, but the structural form of the two first heaters 4 can be adaptively adjusted according to the position and installation requirement, and the power of the two second heaters 5 is the same, but the structural form of the two second heaters 5 can be adaptively adjusted according to the position and installation requirement.
[0041] In some embodiments, the multi-drum washing machine further comprises a direct-draft drying assembly, and the direct-draft drying assembly is in communication with the second drum 3.
[0042] When the direct-draft drying assembly works, hot air is delivered into the second drum 3, and the wet hot air in the second drum 3 is directly discharged. Since the wet hot air is directly discharged during drying, the power required by the heater of the direct-draft drying assembly is lower than that of the heater in the condensing drying assembly. Therefore, when the second drum 3 adopts the direct-draft drying assembly, the first drum 2 and the second drum 3 can simultaneously perform the drying operation without power overload, and accordingly, the first heater 4 can also have higher power to better improve the drying efficiency of the first drum 2.
[0043] Optionally, the multi-drum washing machine may further include a condensing drying assembly that is in communication with the first drum 2. This arrangement can effectively protect the clothes in the first drum 2 and improve user satisfaction. Alternatively, another inline drying assembly may also be provided that is in communication with the first drum 2.
[0044] In some embodiments, the ratio of the inner volume of the first drum 2 to the inner volume of the second drum 3 is less than or equal to 60. This configuration effectively prevents the inner volume of the second drum 3 from being too small, thereby affecting the washing and drying efficiency of the clothes.
[0045] Optionally, the inner cylinder depth of the first drum 2 can be equal to the inner cylinder depth of the second drum 3, or the former can be greater than the latter. The inner cylinder volume of the first drum 2 can be 61L, and the inner cylinder volume of the second drum 3 can be 3L.
[0046] In some embodiments, the ratio of the inner drum volume of the first drum 2 to the inner drum volume of the second drum 3 is less than or equal to 20. In this case, while the inner drum volume of the first drum 2 remains unchanged, the inner drum volume of the second drum 3 can be set to be larger, thereby completing the washing and drying operations of more clothes at one time, and the washing and drying efficiency of the second drum 3 is higher.
[0047] In some embodiments, the outer contour of the shell 1 is a rectangular parallelepiped, the width of the shell 1 is 550 mm-650 mm, the height of the shell 1 is 800 mm-900 mm, and the first roller 2 and the second roller 3 are arranged at intervals along the height direction of the shell 1.
[0048] That is, the multi-drum washing machine of this embodiment is of standard size. While satisfying the simultaneous washing and drying operations of the first drum 2 and the second drum 3, the size of the shell 1 will not be changed, thereby effectively reducing the modification cost of the multi-drum washing machine.
[0049] Optionally, the width of the housing 1 can be 550mm, 600mm and 650mm, and the height of the housing 1 can be 800mm, 850mm and 900mm. The second roller 3 can be located directly above the first roller 2 or above the side of the first roller 2.
[0050] In some embodiments, as Figure 1 As shown, there is one second drum 3. That is, the multi-drum washing machine has two drums, which can form two areas to complete the washing and drying of different types of clothes.
[0051] Or, as Figure 2 As shown, there are two second rollers 3 , and the two second rollers 3 are arranged at intervals along the width direction of the shell 1 .
[0052] That is, the multi-cylinder washing machine has three rollers, thereby being capable of classifying clothes into three categories and performing washing and drying operations respectively, and the user satisfaction is higher.
[0053] Optionally, when the number of the second rollers 3 is two, one of the two second rollers 3 and the first roller 2 can complete the same washing and drying operation, or the three of the two second rollers 3 and the first roller 2 can complete the same washing and drying operation.
[0054] In some embodiments, the multi-cylinder washing machine further comprises a third roller, and an inner cylinder volume of the third roller is smaller than an inner cylinder volume of the first roller 2.
[0055] That is, the inner cylinder volume of the third roller and the inner cylinder volume of the second roller 3 are not equal, and the fifth heater and the sixth heater can be installed on the outer cylinder of the third roller to have heating washing and drying operations, and the same washing and drying operations of the three categories of clothes can be completed in combination with the first roller 2 and the second roller 3, thereby improving the user satisfaction.
[0056] In some embodiments, the shortest distance between the first roller 2 and the second roller 3 is 3mm-100mm.
[0057] At this time, when the first heater 4 and the second heater 5 work simultaneously to complete the heating washing operation or the drying operation of the first roller 2 and the second roller 3 respectively, the heat dissipated from any one of the first roller 2 and the second roller 3 can be transmitted to the other one of the first roller 2 and the second roller 3, thereby realizing the mutual reuse of the heat, improving the heating efficiency, and effectively reducing the power requirement of the first heater 4 and the second heater 5 to avoid the power overload when the two work simultaneously.
[0058] Optionally, the shortest distance between the first roller 2 and the second roller 3 is equal to the distance between the center line of the first roller 2 and the center line of the second roller 3 minus the outer cylinder radius of the first roller 2 and the outer cylinder radius of the second roller 3, and specifically can be 3mm, 25mm, 50mm and 100mm.
