Description

Clothes treatment device

The present invention relates to a clothes treating device with a moisture absorption wheel element.

For the washing machine industry, fully automatic washing machines that can dry clothes after washing are increasingly favored by consumers, as this function is particularly useful in humid weather. Traditional clothes treatment devices are generally divided into exhaust type, condensation type and heat pump type. These three types of clothes treatment devices are getting better and better in drying effects, but the prices are also getting more and more expensive accordingly. In order to reduce the price while ensuring satisfactory drying effects, clothes treatment devices based on moisture-absorbing materials have recently been proposed. In this type of clothes treatment device, a moisture absorption disk made of moisture absorption material is rotatably supported in a housing, the inner cavity of which is divided into a moisture absorption area and a moisture discharge area. The moisture absorption disk absorbs moisture when rotating to the moisture absorption area and discharges moisture when rotating to the moisture discharge area, thereby having a continuous moisture absorption capacity, so that the airflow circulating through the drum and the moisture absorption disk can dry the clothes in the drum. However, the drum in the clothes treatment device may cause vibration during operation, and sometimes even cause vibration of the entire clothes treatment device, which may be transmitted to the moisture absorption disk, causing it to deviate in the radial direction. This radial deviation may cause the moisture absorption disc to deviate from the rotation axis, thereby increasing the rotation resistance and causing wear of the center area of the moisture absorption disc and the corresponding shaft components. On the other hand, the instantaneous radial deviation may also cause the moisture absorption disc to collide with the inner periphery of the housing, directly causing damage to the moisture absorption disc.

In order to overcome the above-mentioned defects, the present invention proposes a clothing processing device, comprising a drum and a drying module, wherein the drying module comprises a moisture absorption and dehumidification component, wherein the moisture absorption and dehumidification component comprises a moisture absorption wheel element, a wheel housing and a wheel driving mechanism for driving the moisture absorption wheel element to rotate, wherein the moisture absorption wheel element is rotatably supported in the wheel housing along a rotation axis, and wherein at least one peripheral roller mechanism is arranged at the inner periphery of the wheel housing, wherein the peripheral roller mechanism comprises a peripheral roller and a peripheral roller bracket, wherein the peripheral roller is rotatably supported in the wheel housing along a rotation axis. The peripheral roller bracket is supported on the peripheral roller bracket, and the peripheral roller bracket is arranged at the inner periphery of the impeller shell, wherein, viewed along the direction parallel to the rotation axis, the peripheral roller is arranged within the size range of the moisture absorption impeller element along the direction of the rotation axis, and viewed along the direction perpendicular to the rotation axis, the peripheral roller is arranged between the moisture absorption impeller element and the impeller shell, and the peripheral roller can be in rolling contact with the outer peripheral surface of the moisture absorption impeller element at least part of the time during the rotation process of the moisture absorption impeller element.

In one technical solution, in the initial installation position, the circumferential roller mechanism rolls with the moisture absorption wheel element without squeezing each other. Thus, the circumferential roller mechanism can always assist the rotation of the moisture absorption wheel element without significantly increasing the rotation resistance of the moisture absorption wheel element, preventing the moisture absorption wheel element from shaking radially during rotation, thereby ensuring its stable rotation.

In an alternative technical solution, in the initial installation position, there is a gap between the circumferential roller mechanism and the moisture absorption wheel element, and when the moisture absorption wheel element deviates in a direction perpendicular to the rotation axis, the moisture absorption wheel element rolls in contact with the circumferential roller mechanism. This can further reduce the rotational resistance of the moisture absorption wheel element during normal rotation, and only works when the moisture absorption wheel element shakes in the radial direction.

In one technical solution, the peripheral roller is configured to be flexible and deformable, thereby being able to simply utilize the deformable characteristics of the peripheral roller to buffer the radial shaking of the moisture-absorbing impeller element. Advantageously, the peripheral roller includes an inner ring, an outer rim, and a hub connecting the inner ring and the outer rim, and the hub is provided in at least two and is configured to be flexible and deformable. It is also advantageous that the connecting line formed by the hub at the connection with the inner ring and the outer rim does not pass through the rotation axis of the roller. Here, the inner ring can be understood as a rotation axis or a tube on which the rotation axis is sleeved. In an alternative technical solution, the hub described above is replaced by a flexible material such as foam, silicone ring, etc., that is, a flexible material is provided between the inner ring and the outer rim. For example, flexible material is arranged on the inner ring outer cover, and then outer rim is arranged on the flexible material outer cover again. Here, outer rim can be arranged to hard, also can be arranged to flexibility.

In an additional or alternative technical solution, the peripheral roller bracket is configured to be displaceable. In particular, the peripheral roller bracket itself can be configured to be elastically deformable. Additionally or alternatively, the peripheral roller bracket is configured to be able to move as a whole along a sliding track to change the distance from the rotation axis, wherein an elastic reset member for returning the peripheral roller bracket to an initial position is fixed on the runner housing. For example, the sliding track is composed of a groove constructed on the runner housing and a sliding block constructed in a matching manner on the peripheral roller bracket. Alternatively, the sliding track is composed of a guide protrusion constructed on the runner housing and a guide claw constructed in a matching manner on the peripheral roller bracket.

In one technical solution, a plurality of peripheral roller mechanisms, preferably six peripheral roller mechanisms, are arranged at the inner periphery of the impeller housing. It is particularly advantageous that the inner periphery of the impeller housing is constructed in a step-like manner, and a peripheral roller bracket is provided on the end surface of the step extending in a direction perpendicular to the rotation axis, i.e., in a radial direction, and the peripheral roller is rotatably supported on the peripheral roller bracket. Preferably, the peripheral surface of the step forms a impeller housing seal, which forms a contact seal with the impeller seal of the moisture-absorbing impeller element. The plurality of peripheral roller mechanisms can be uniformly or non-uniformly arranged at the inner periphery of the impeller housing. It is particularly advantageous that, when the moisture absorption wheel element is driven at its outer periphery by the wheel drive mechanism, a plurality of peripheral roller mechanisms are arranged unevenly at the inner periphery of the wheel housing, wherein more peripheral roller mechanisms are arranged on the side away from the contact portion of the wheel drive mechanism and the moisture absorption wheel element. For example, when the wheel drive mechanism and the moisture absorption wheel element interact in the form of a gear engagement, the gear engagement portion is the contact portion of the wheel drive mechanism and the moisture absorption wheel element, and it is advantageous to arrange more peripheral roller mechanisms on the side away from the gear engagement portion. For another example, when the impeller driving mechanism and the moisture absorption wheel element interact with each other in the form of a pulley, the position where the belt in the impeller driving mechanism and the outer periphery of the moisture absorption wheel element squeeze each other is the contact point between the impeller driving mechanism and the moisture absorption wheel element. At this time, it is beneficial to arrange more peripheral roller mechanisms on the side away from the squeezed position.

In one technical solution, the peripheral roller at least partially protrudes from the inner peripheral wall of the runner housing only at its axial height, and does not necessarily protrude toward the rotation axis relative to all inner peripheral surfaces of the runner housing. In another technical solution, the peripheral roller at least partially protrudes from the entire inner peripheral wall of the inner periphery of the runner housing toward the rotation axis, and is closer to the rotation axis than all inner peripheral surface sections of the inner periphery of the runner housing.

In one technical solution, the moisture-absorbing wheel element has a peripheral shell part, and an auxiliary rotating ring for rolling cooperation with the peripheral roller mechanism is constructed on the outer peripheral surface of the peripheral shell part, and the auxiliary rotating ring is constructed as an annular protrusion. A power input part for introducing power from the wheel drive mechanism to rotate the moisture-absorbing wheel element and a wheel seal for forming a relatively rotatable contact seal with a wheel shell seal arranged on the inner peripheral surface of the wheel shell are also constructed on the outer peripheral surface of the peripheral shell part. The power input part, the auxiliary rotating ring and the wheel seal are completely staggered along the direction of the rotation axis on the outer peripheral surface of the peripheral shell part and are arranged in sequence from top to bottom. It is conceivable that the power input member, the auxiliary rotating ring and the runner seal can also be arranged in another order along the rotation axis in a staggered manner. The power input member and the auxiliary rotating ring can be integrally constructed or separately constructed.

In one technical solution, the peripheral roller support is fixed to the impeller housing by means of a fixing mechanism, and the fixing mechanism is configured to be able to adjust the radial spacing between the peripheral roller support and the moisture absorption impeller element in the initial installation position. As a result, the peripheral roller mechanism can be applied to more sizes of moisture absorption impeller elements and can be applied to more operating modes.

The clothes treating device proposed by the present invention can limit the deviation of the moisture absorption wheel element during rotation in a direction perpendicular to the rotation axis of the moisture absorption wheel element, thereby improving the running stability of the moisture absorption wheel element and reducing the risk of collision between the moisture absorption wheel element and the wheel housing.

A drying module is also the subject of the present invention, which can comprise a single feature or a combination of multiple features described above in relation thereto, and thus has the same or similar advantages as the clothes treatment device according to the present invention.

FIG1 shows a three-dimensional diagram of an embodiment of a clothing treatment device according to the present invention. In one technical solution, the clothing treatment device is a washing and drying machine. For the sake of clarity, FIG1 omits part of the outer shell of the clothing treatment device. In this embodiment, the clothing treatment device W includes a water inlet, a water outlet, a drum R, a drum drive unit, and a drying module D. The drum includes an inner drum and an outer drum, the drum drive unit is transmission-connected to the inner drum to drive the inner drum to rotate, the outer drum is configured to be suspended or hoisted on the clothing treatment device frame, and the water inlet and the water outlet are respectively connected to the drum R. The drying module D includes a moisture absorption and discharge component D1, a moisture absorption channel D2, and a moisture discharge channel D3. The moisture absorption channel D2 includes a moisture absorption channel air inlet and a moisture absorption channel air outlet, and the roller R is connected to the moisture absorption channel air inlet and the moisture absorption channel air outlet respectively, and a moisture absorption channel fan D23 is also provided in the moisture absorption channel D2 to form a circulating moisture absorption airflow in the roller R and the moisture absorption channel D2. A moisture exhaust channel fan D33 is provided in the moisture exhaust channel D3 to form a moisture exhaust airflow in the moisture exhaust channel D3. The moisture absorption and discharge component D1 is arranged in the path of the moisture absorption channel D2 and the moisture discharge channel D3, so that the moisture absorption airflow and the moisture discharge airflow both flow through the moisture absorption and discharge component D1, so that the moisture absorption and discharge component D1 absorbs moisture in the moisture absorption airflow during the rotation process and discharges the absorbed moisture through the moisture discharge airflow. Of course, the clothing processing device W may also include but is not limited to an outer shell with at least a clothing access port and a detergent delivery port, a door body for closing the clothing access port, a display and operating device arranged on the outer shell, a frame, a controller, a drain pipe and other components to realize the washing and drying functions of the clothing and the control of the clothing processing device.

Fig. 2 exemplarily shows an exploded view of the moisture absorption and dehumidification component D1. Fig. 3 exemplarily shows a three-dimensional view of a moisture absorption wheel element D11 and a lower impeller shell D12L with a peripheral roller mechanism D122. The moisture absorption and dehumidification component D1 includes a moisture absorption wheel element D11, a impeller shell D12 and a impeller drive mechanism D13. The impeller shell D12 includes an upper impeller shell D12U and a lower impeller shell D12L, which are fixed to each other to form an internal cavity. The moisture absorption wheel element D11 is rotatably supported along its rotation axis in the internal cavity of the impeller shell D12 and rotates under the drive of the impeller drive mechanism D13. The moisture absorption wheel element D11 is driven by the wheel driving mechanism D13 at its outer periphery, that is, the wheel driving mechanism D13 applies the driving force outputted by it to the outer periphery of the moisture absorption wheel element D11. In this embodiment, the moisture absorption wheel element D11 and the wheel driving mechanism D13 are arranged substantially side by side in a direction perpendicular to the rotation axis of the moisture absorption wheel element D11, that is, in a radial direction. The wheel housing D12 has a housing portion for housing the moisture absorption wheel element D11 and the wheel driving mechanism D13, respectively.

The impeller housing D12 also has a moisture absorption air flow inlet and a moisture absorption air flow outlet. Viewed along the rotation axis of the moisture absorption wheel element D11, the moisture absorption air flow inlet and the moisture absorption air flow outlet of the impeller housing D12 are arranged on both sides of the moisture absorption wheel element D11 so that the moisture absorption air flow can flow through the moisture absorption wheel element D11. When the moisture absorption air flow flows through the moisture absorption wheel element D11, the moisture in the moisture absorption air flow can be absorbed by the moisture absorption wheel element D11, thereby making the moisture absorption air flow flowing out of the moisture absorption wheel element D11 dry, and the dry air flow is later transported to the drum R to take away the moisture in the drum R. The impeller housing D12 also has a dehumidification airflow inlet and a dehumidification airflow outlet. Viewed along the rotation axis of the dehumidification wheel element D11, the dehumidification airflow inlet and the dehumidification airflow outlet of the impeller housing D12 are also arranged on both sides of the dehumidification wheel element D11 so that the dehumidification airflow can flow through the dehumidification wheel element D11. When the dehumidification airflow flows through the dehumidification wheel element D11, the moisture in the dehumidification wheel element D11 is taken away by the supplied dry dehumidification airflow to achieve the regeneration of the dehumidification wheel element D11, thereby ensuring the continuous dehumidification capacity of the dehumidification wheel element D11. The impeller housing D12 has at least two pairs of partition ribs D121 extending toward each other and facing each other on the inner walls of the end surfaces of the impeller upper housing D12U and the impeller lower housing D12L, so as to divide the inner space of the impeller housing D12 into a moisture absorption area D1211 and a moisture discharge area D1212, so that the moisture absorption airflow and the moisture discharge airflow are separated inside the impeller housing D12. In some other technical solutions, partition ribs can be provided only on the inner walls of the end surfaces of the impeller upper housing D12U or the impeller lower housing D12L, and the number of partition ribs can also be other numbers greater than two.

When the clothes treatment device W enters the drying mode, the moisture absorption channel fan D23 is controlled to start, thereby forming a moisture absorption airflow in the moisture absorption channel D2. When the moisture absorption airflow flows through the drum R, it takes away part of the moisture in its inner cavity, and then the humid airflow flows into the moisture absorption and discharge component D1. There, the humid moisture absorption airflow passes through the moisture absorption airflow inlet of the impeller housing D12, enters the moisture absorption area D1211 of the impeller housing D12, and passes through the rotating moisture absorption impeller element D11. Since the wheel disc D111 in the moisture absorption wheel element D11 has moisture absorption characteristics, the moisture absorption airflow is dried when passing through the moisture absorption wheel element D11, and the moisture absorption airflow flowing out of the moisture absorption wheel element D11 becomes dry, and the dry moisture absorption airflow is transported to the drum again, and the cycle is repeated until the preset drying effect is achieved. However, the moisture absorption capacity of the wheel disc D111 is limited. After a period of time, the wheel disc D111 will reach a saturated state and will no longer be able to absorb more moisture. For this purpose, a dehumidification channel is set up, and the dehumidification channel fan D33 is started at an appropriate time under the control of the controller, thereby forming a dehumidification airflow in the dehumidification channel. The dehumidification channel can be connected to the external environment or can be an internal loop, but in any case, it is necessary to ensure that the airflow entering the dehumidification area D1212 of the moisture absorption wheel element D11 through the dehumidification channel entrance is dry, so that the moisture in the rotating wheel can be desorbed and taken away with the dehumidification airflow. In this way, the wheel D111 absorbs moisture when it rotates to the moisture absorption area D1211 and discharges moisture when it rotates to the dehumidification area D1212, thereby having a continuous moisture absorption capacity.

As shown in Fig. 2 and Fig. 3, a plurality of peripheral roller mechanisms D122 are arranged at the inner periphery of the runner housing D12. The peripheral roller mechanism D122 includes a peripheral roller D1221 and a peripheral roller bracket D1222, wherein the peripheral roller D1221 is rotatably supported on the peripheral roller bracket D1222 and the peripheral roller bracket D1222 is arranged at the inner periphery of the runner housing D12. Viewed in the direction parallel to the rotation axis of the moisture absorption wheel element D11, i.e., in the axial direction, the peripheral roller D1221 is arranged within the axial dimension range of the moisture absorption wheel element D11, i.e., the peripheral roller D1221 is arranged within the thickness range of the moisture absorption wheel element D11. Viewed in the direction perpendicular to the rotation axis of the moisture absorption wheel element D11, i.e., in the radial direction, the peripheral roller D1221 is arranged between the moisture absorption wheel element D11 and the wheel shell D12, and the peripheral roller D1221 can be in rolling contact with the outer peripheral surface of the moisture absorption wheel element D11 at least partially during the rotation process of the moisture absorption wheel element D11.

As shown in FIG3 , the inner periphery of the runner lower housing D12L is constructed in a step-like manner, and a peripheral roller bracket D1222 is provided on the end surface of the step extending in a direction perpendicular to the rotation axis, i.e., in a radial direction, and the peripheral roller D1221 is rotatably supported on the peripheral roller bracket D1222. In this embodiment, the assembled peripheral roller D1221 at least partially protrudes from the entire inner peripheral wall of the inner periphery of the runner housing D12 toward the rotation axis, and in particular, also protrudes from the peripheral surface of the step. The circumferential surface of the step forms a runner housing seal D124 in this embodiment, that is, the runner housing seal is formed by the inner wall of the runner housing itself, and forms a contact seal with the runner seal D116 of the moisture-absorbing runner element D11. In other technical solutions, the runner housing seal can also be a structure that is formed separately and mounted on the inner wall of the runner housing, or a structure that is integrally formed on the inner wall of the runner housing. Of course, it is also conceivable that the assembled peripheral roller protrudes from the inner circumferential wall of the runner housing only at its axial height, and may not be the most protruding structure on the inner periphery of the runner housing, as long as the moisture-absorbing runner element can be in rolling contact with it at least part of the time during the rotation process.

Therefore, when the moisture absorption wheel element D11 is radially offset, the circumferential roller mechanism D122 will limit the moisture absorption wheel element D11 in the form of rolling contact, thereby assisting the moisture absorption wheel element D11 to run on its set rotation track without causing significant rotational resistance, and especially preventing it from directly hitting the wheel housing D12 itself, thereby reducing the risk of damage to the moisture absorption wheel element D11.

In the illustrated embodiment, in the initial installation position, the circumferential roller mechanism D122, especially the circumferential roller D1221 therein, is in rolling contact with the outer peripheral surface of the moisture absorption wheel element D11, preferably in rolling contact without mutual squeezing. As a result, the circumferential roller mechanism D122 can always assist the rotation of the moisture absorption wheel element D11 without significantly increasing the rotation resistance of the moisture absorption wheel element D11, preventing the moisture absorption wheel element D11 from shaking radially during rotation, thereby ensuring its stable rotation.

In other technical solutions, in the initial installation position, there is a small gap between the peripheral roller mechanism, especially the peripheral roller therein, and the outer peripheral surface of the moisture absorption wheel element, so that the moisture absorption wheel element does not contact the peripheral roller mechanism when rotating around the set rotation axis, but only rolls with the peripheral roller mechanism when the moisture absorption wheel element deviates in a direction perpendicular to the rotation axis, that is, radially. The peripheral roller mechanism can protect the moisture absorption wheel element from directly colliding with the wheel housing.

Particularly advantageously, the circumferential roller mechanism D122 is configured to be deformable. In the illustrated embodiment, the circumferential roller D1221 in the circumferential roller mechanism D122 is configured to be flexible and deformable. This enables, when the moisture absorption wheel element D11 deviates radially, the flexible and deformable characteristics of the circumferential roller D1221 can be utilized to buffer such deviation.

In an additional or alternative technical solution, the peripheral roller support in the peripheral roller mechanism can be configured to be deflectable, so that when the moisture absorption wheel element deflects in the radial direction, the peripheral roller support deflects under the condition of being squeezed, so that the spacing of the peripheral roller relative to the rotation axis or the set rotation axis of the moisture absorption wheel element changes. In a technical solution, the peripheral roller support itself is configured to be elastically deformable. In another technical solution, the peripheral roller bracket is configured to move along a sliding track as a whole to change the distance from the rotation axis, wherein an elastic reset member, such as a spring, is fixed on the runner housing for returning the peripheral roller bracket to an initial position. Specifically, the sliding track is composed of a groove constructed on the runner housing and a sliding block constructed on the peripheral roller bracket in a matching manner, or the sliding track is composed of a guide protrusion constructed on the runner housing and a guide claw constructed on the peripheral roller bracket in a matching manner.

FIG4 exemplarily shows a top view of a lower housing D12L of a runner with a peripheral roller mechanism D122. Six peripheral roller mechanisms D122 are arranged at the inner periphery of the runner housing D12. In order to clearly show the peripheral roller brackets D1222, only two peripheral roller mechanisms D122 with peripheral rollers D1221 are shown in FIG4, and the remaining four only show the peripheral roller brackets D1222. These peripheral roller mechanisms D122 are evenly distributed at the inner periphery of the runner housing on the same circumference in the illustrated embodiment. The peripheral roller bracket D1222 is provided with a circular hole, and the rotating shaft of the peripheral roller D1221 is inserted into the circular hole. The peripheral roller bracket D1222 can be formed integrally with the runner shell D12, or can be manufactured separately and then fixed together with the runner shell D12. Since the impeller is driven circumferentially, it is inevitable that a certain degree of eccentric force will be caused to the impeller. The circumferential roller mechanism can also be arranged in an uneven manner. For example, more circumferential roller mechanisms are arranged on the side away from the contact portion between the impeller drive mechanism and the moisture absorption impeller element to offset the influence of the above-mentioned eccentric force, and a small number of circumferential roller mechanisms are arranged on the side close to the contact portion between the impeller drive mechanism and the moisture absorption impeller element. For example, when the runner drive mechanism and the moisture absorption wheel element interact with each other in the form of gear engagement, the gear engagement portion is the contact portion between the runner drive mechanism and the moisture absorption wheel element. At this time, it is advantageous to arrange more peripheral roller mechanisms on the side away from the gear engagement portion. For another example, when the runner drive mechanism and the moisture absorption wheel element interact with each other in the form of a belt pulley, the position where the belt in the runner drive mechanism and the outer periphery of the moisture absorption wheel element are squeezed with each other is the contact portion between the runner drive mechanism and the moisture absorption wheel element. At this time, it is advantageous to arrange more peripheral roller mechanisms on the side away from the squeezed portion.

In some technical solutions, the peripheral roller bracket is fixed to the impeller housing by means of a fixing mechanism, and the fixing mechanism is configured to be able to adjust the radial spacing between the peripheral roller bracket and the moisture absorption impeller element in the initial installation position. As a result, the peripheral roller mechanism can be applicable to more sizes of moisture absorption impeller elements and can be applicable to more operating modes, such as the mode of contacting with the moisture absorption impeller element in the initial state and the mode of not contacting with the moisture absorption impeller element in the initial state described above.

Fig. 5 exemplarily shows the peripheral roller D1221. In this embodiment, the peripheral surface of the peripheral roller D1221 is basically smoothly constructed. In other technical solutions, the peripheral surface of the peripheral roller is constructed with an uneven surface structure. The peripheral roller D1221 includes a roller body and a rotating shaft. In some technical solutions, the roller body is rotatable relative to the rotating shaft, and it is only necessary to connect the rotating shaft and the peripheral roller bracket so that they cannot rotate relative to each other, such as by clamping them together. In other technical solutions, the roller body cannot rotate relative to the rotating shaft, and in this case, the rotating shaft and the peripheral roller bracket need to be connected so that they can rotate relative to each other. The peripheral roller D1221 includes an inner ring, an outer rim, and a wheel hub connecting the inner ring and the outer rim. The wheel hubs are arranged as at least two and are flexible and deformable; the wheel hubs may optionally form a line at the connection between the inner ring and the outer rim that does not pass through the rotation axis of the roller; the inner ring may be understood as a rotation axis or a tube on which the rotation axis is sleeved. Of course, the wheel hubs may also be replaced by flexible materials, such as foam, silicone rings, etc., with a flexible material being disposed outside the inner ring, and then an outer rim being disposed outside the flexible material. The outer rim may be hard or flexible. FIG6 exemplarily shows an exploded view of the moisture-absorbing rotor element D11. In this embodiment, the moisture-absorbing wheel element D11 includes a wheel disc D111, a peripheral shell member D112, and a power input member D114, an auxiliary rotating ring D115 and a wheel seal D116 constructed at the outer periphery of the peripheral shell member D112.

In the illustrated embodiment, the peripheral shell member D112 is composed of a peripheral upper shell body D112U and a peripheral lower shell body D112L of annular structure. The peripheral upper shell body D112U has a longitudinal section similar to an L-shape and includes an end section extending in a radial direction and a circumferential section extending in an axial direction. Similarly, the peripheral lower shell body D112L also has a longitudinal section similar to an L-shape and includes an end section extending in a radial direction and a circumferential section extending in an axial direction. The upper outer shell body D112U and the lower outer shell body D112L are connected to each other by means of buckles and slots formed thereon, thereby forming a groove with only one side open for accommodating the peripheral area of the wheel disk D111 on the inner side. In the connected state, the upper outer shell body D112U and the lower outer shell body D112L surround the entire outer peripheral surface of the wheel disk D111 and clamp the wheel disk D111 from the upper and lower end surfaces of the peripheral area, respectively, so that the outer shell body D112 and the wheel disk D111 are connected together in a non-rotatable manner.

In the illustrated embodiment, an auxiliary rotating ring D115 is provided on the outer peripheral surface of the outer peripheral upper clamping shell D112U. The auxiliary rotating ring D115 can be formed integrally with the outer peripheral upper clamping shell D112U, or can be manufactured separately and then fixed, for example, welded or bonded to the outer peripheral surface of the outer peripheral upper clamping shell D112U. The auxiliary rotating ring D115 is arranged to match the position of the peripheral roller mechanism D122, especially the peripheral roller D1221 therein, so as to roll with the peripheral roller D1221 in the peripheral roller mechanism D122, as shown in FIG2. Of course, it is also conceivable that the auxiliary rotating ring is provided on the outer peripheral lower clamping shell.

In the illustrated embodiment, the auxiliary rotating ring D115 is constructed as an annular protrusion, and the degree of its protrusion is to ensure that it can roll in contact with the peripheral roller D1221, even if the peripheral roller is not the most prominent structure on the inner periphery of the wheel housing. In other technical solutions, the auxiliary rotating ring can also be formed by the basic surface of the peripheral housing member itself. The peripheral surface of the auxiliary rotating ring can be smoothly constructed or constructed with an uneven surface structure.

In the illustrated embodiment, a power input member D114 for introducing power from the impeller drive mechanism D13 to rotate the moisture-absorbing impeller element D11 and an impeller seal D116 for forming a relatively rotatable contact seal with an impeller housing seal D124 disposed on the inner circumference of the impeller housing D12 are also disposed on the outer circumference of the outer circumferential clamping housing D112U. The power input member D114, the auxiliary rotating ring D115 and the impeller seal D116 are completely staggered along the direction of the rotation axis on the outer circumference of the outer housing member D112 and are disposed sequentially from top to bottom. It is conceivable that the power input member D114, the auxiliary rotating ring D115 and the runner seal D116 can also be arranged in another order along the rotation axis in a staggered manner. Of course, it is also conceivable that they are arranged on the outer peripheral surface of the outer peripheral lower clamping shell D112L or distributed on the outer peripheral upper clamping shell D112U and the outer peripheral lower clamping shell D112L. The power input member D114 and the auxiliary rotating ring D115 are constructed as a whole here, but of course they can also be constructed separately.

Fig. 7 shows the peripheral roller D1221 and the auxiliary rotating ring D115 in rolling contact. In the illustrated embodiment, the wheel seal D116 forms the maximum diameter of the moisture-absorbing wheel element D11, and the peripheral roller mechanism D122 protrudes from the entire inner peripheral wall of the inner periphery of the wheel housing D12 toward the axis of rotation to roll in contact with the auxiliary rotating ring D115 of a smaller diameter. It is also conceivable that the auxiliary rotating ring forms the maximum diameter of the moisture absorption wheel element, and the runner housing seal that cooperates with the runner seal is closer to the rotation axis as part of the inner peripheral surface of the runner housing than the peripheral roller mechanism, and the peripheral roller only needs to protrude from the inner peripheral wall at the axial height where it is located. It should be noted here that if there is a gap between the peripheral roller mechanism and the auxiliary rotating ring in the initial installation position, the size of the gap should be small enough to ensure that: when the moisture absorption wheel element is radially offset, the runner seal can still rotate relative to the runner housing seal. That is, the auxiliary rotating ring of the moisture-absorbing impeller element should be in rolling contact with the peripheral roller mechanism before the deformation capacity of the impeller seal is consumed to avoid the impeller seal from getting stuck relative to the impeller housing seal.

The drying module described above can also be applied to various fields requiring dehumidification, such as dryers, dehumidifiers, dishwashers, etc.

It should be understood that the above embodiments are only for the purpose of example and description, and are not intended to limit the present invention to the described embodiments. In other words, the present invention can also be implemented in various other combinations of the features mentioned above, and is not limited to the embodiments shown and described.

The above is only the preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
