Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be illustrative of the invention and are not to be construed as limiting the invention.

Referring to fig. 1 to 18, according to the drying apparatus 2 of the embodiment of the present invention, the drying apparatus 2 includes: a container 21 and a first diverter 22.

Specifically, the container 21 has a first channel 201 and a second channel 202 separated from each other, and the container 21 is provided with a first port 203, a second port 204, a third port 205, and a fourth port 206, so that when the airflow is dried, the airflow can flow into and out of the first channel 201 and the second channel 202 from the first port 203, the second port 204, the third port 205, and the fourth port 206, and the airflow in the container 21 can flow along the first channel 201 or the second channel 202.

The first direction changing member 22 has a first state and a second state, and referring to fig. 3 to 6 and 11 to 14, the first direction changing member 22 connects the first port 203 and the first end of the first channel 201, and connects the second port 204 and the first end of the second channel 202 in the first state. Referring to fig. 7 to 10 and 15 to 18, in the second state, the first direction changing member 22 connects the first port 203 and the first end of the second channel 202, and connects the second port 204 and the first end of the first channel 201. In other words, by providing the first direction changing member 22, one of the first interface 203 and the second interface 204 can be selectively connected to one of the first channel 201 and the second channel 202, and the other of the first interface 203 and the second interface 204 can be selectively connected to the other of the first channel 201 and the second channel 202. Specifically, the method at least comprises the following steps: the first interface 203 is communicated with the first channel 201, and the second interface 204 is communicated with the second channel 202; the first interface 203 connects the second channel 202, and the second interface 204 connects the first channel 201.

In addition, it should be noted that the first direction-changing member 22 may have a first state and a second state, which does not mean that the first direction-changing member 22 only has the first state and the second state, and the first direction-changing member 22 may also have a third or more states, for example, the first interface 203, the second interface 204, the first channel 201 and the second channel 202 are all connected.

The third port 205 and the fourth port 206 communicate with the second end of the first passage 201 and the second end of the second passage 202, respectively. The connection mode between the third interface 205 and the fourth interface 206 and the first channel 201 and the second channel 202 may be a fixed mode or a switchable mode. For example, the third interface 205 is always connected to the second end of the first channel 201, and the fourth interface 206 is always connected to the second end of the second channel 202; or the third interface 205 is always kept connected with the second end of the second channel 202, and the fourth interface 206 is always kept connected with the second end of the first channel 201; or, the connection mode between the third interface 205 and the fourth interface 206 and the first channel 201 and the second channel 202 can be switched. As for the aforementioned "the connection mode between the third interface 205 and the fourth interface 206 and the first channel 201 and the second channel 202 is switchable", the method may include: the third interface 205 is communicated with the first channel 201, and the fourth interface 206 is communicated with the second channel 202; or the third interface 205 is communicated with the second channel 202, and the fourth interface 206 is communicated with the first channel 201; and so on.

According to the drying device 2 of the embodiment of the invention, in the drying process or under different drying conditions, the state can be switched through the first reversing piece 22, the flowing direction of the fluid is changed, and the drying effect is improved.

Taking the first interface 203 and the second interface 204 as air inlets for drying air, the air flow enters the drying device 2 through the first interface 203 and the second interface 204, the first interface 203 is connected to the air flow to be dried, when the first reversing element 22 is in the first state, the air flow to be dried enters the first channel 201 for drying, and after drying is completed, the air flow is sent out from the third interface 205 or the fourth interface 206; the second port 204 may be connected to the outside air or in another state (e.g., in a closed state), and at this time, the drying is performed through the first channel 201, and after a predetermined condition is reached, the airflow to be dried is guided into the second channel 202 by the reversing action of the first reversing member 22 to continue the drying.

For this example, the second interface 204 may be connected to external air, and dry (or water-absorbing) media may be disposed in both the first channel 201 and the second channel 202, when the first reversing element 22 is in the first state, the airflow to be dried enters the first channel 201 to be dried, and after a period of drying, the dry media may be in a state of water saturation, at this time, the first reversing element 22 may be switched to the second state, at this time, the airflow with drying enters the second channel 202 to be dried, and, as the external air enters the first channel 201, water and the like in the first channel 201 will be taken away, in other words, the dry media in the first channel 201 is regenerated, and after a period of drying, the first switching key may be switched to the first state. By means of the switching, the drying effect and efficiency can be improved. Greatly reduces the cost, saves energy and protects environment.

In addition, it should be noted that the above is only a specific example of the present invention, and is not meant to limit the scope of the present invention, for example, the first interface 203 and the second interface 204 can also be used as outlets, and still take the example of air drying, and the air flow can be guided to different positions by switching the first direction-changing member 22 and the second direction-changing member 23, which will be described in the following in the washing apparatus such as the dishwasher 100.

In some embodiments of the present invention, the arrangement directions of the first port 203 and the second port 204 and the arrangement directions of the first end of the first channel 201 and the first end of the second channel 202 may be set to be perpendicular to each other, so that the first port 203 and the second port 204 may correspond to different channels and different channels easily, thereby simplifying the structure of the first reversing element 22 and facilitating the first reversing element 22 to switch quickly.

Of course, in the present invention, the arrangement directions of the first interface 203 and the second interface 204 and the arrangement directions of the first end of the first channel 201 and the first end of the second channel 202 may also be set in other forms, and only the first direction changing member 22 is required to switch between the interfaces and the channels.

In some embodiments, in combination with fig. 1 to 18, the first end of the first channel 201 and the first end of the second channel 202 are arranged at intervals in the first direction (refer to the left-right direction in fig. 1 to 18), and the first port 203 and the second port 204 are arranged at intervals in the second direction (refer to the front-back direction in fig. 5 and 6, or the direction perpendicular to the paper surface in fig. 3 and 4). The first end of the first channel 201, the first end of the second channel 202 and the first interface 203 encircle the first commutator 22 in projection along a second direction, the first direction and the second direction being perpendicular to each other. In other words, the first interface 203 will correspond to the first end of the first channel 201 and the first end of the second channel 202, and the first interface 203 will be easily connected to the first end of the first channel 201 or the first end of the second channel 202; while the second port 204 will also correspond to the first end of the first channel 201 and the first end of the second channel 202, the second port 204 will also easily communicate with the first end of the first channel 201 and the first end of the second channel 202. Under the action of the first reversing piece 22, the communication state of the interface and the channel can be switched rapidly.

Alternatively, referring to fig. 3 to 20, the first direction changing member 22 includes: a first diverter tray 221, a first baffle 222, and a second baffle 223. The first rotating disc 221 is arranged in the container 21 in a manner of rotating around an axis parallel to the second direction, the first rotating disc 221 extends along a direction perpendicular to the second direction, and two opposite sides of the first rotating disc 221 along the second direction are respectively communicated with the first interface 203 and the second interface 204; the first guide plate 222 is connected with the first rotating disc 221 and is opposite to the first port 203, the first guide plate 222 extends obliquely to the first port 203 to the first end of the first channel 201 in the first state of the first reversing element 22, and the first guide plate 222 extends obliquely to the first port 203 to the first end of the second channel 202 in the second state of the first reversing element 22; the second baffle 223 is connected to the first rotary plate 221 and faces the second port 204, the first direction-changing member 22 in the first state extends obliquely relative to the second port 204 to the first end of the second passage 202, and the first direction-changing member 22 in the second state extends obliquely relative to the second port 204 to the first end of the first passage 201.

The air flow between the first interface 203 and the second interface 204 and between the first channel 201 and the second channel 202 can be separated at two sides of the first turntable 221 by the isolation effect of the first turntable 221, and then the air flow can be guided to a predetermined position by the guide effect of the first guide plate 222 and the second guide plate 223, so that the guide effect on the air flow is realized, and the mode is simpler and more convenient to control.

Alternatively, referring to fig. 20, the first baffle 222 and the second baffle 223 are arranged to cross at 90 ° in projection along the second direction. At this time, the rotation center axis of the first rotary plate 221 may be disposed at the intersection of the first guide plate 222 and the second guide plate 223, and at this time, during the rotation of the first direction changing member 22, the first direction changing member 22 may switch to a state every 90 ° rotation, and the switching is not directional, that is, the first direction changing member 22 may always rotate in one direction, and the state may change every 90 ° rotation. The first direction change member 22 is controlled in a simpler manner, and the drive member does not need to change its direction when it is arranged to drive the first direction change member 22 to rotate, so that the cost of the drive member is greatly reduced.

Of course, the first guide plate and the second guide plate may be arranged in other forms, for example, the included angle between the first guide plate and the second guide plate may be arranged in other angles. For another example, at least one of the first guide plate and the second guide plate is provided in an arc shape or other shape.

In some embodiments, referring to fig. 3 to 18, a partition 211 is disposed in the container 21 opposite to the first port 203 and the second port 204, the first direction-changing member 22 is disposed between the partition 211 and the first port 203 and between the partition 211 and the second port 204 in a self-transferring manner, the partition 211 closes a portion of the first end of the first passage 201 and a portion of the first end of the second passage 202 that are close to each other, and the partition 211 cooperates with the first direction-changing member 22 to separate the first end of the first passage 201 and the first end of the second passage 202 when the first direction-changing member 22 is in the first state and the second state.

Through the isolation effect of the partition 211, the intercommunication of the air flow between the first channel 201 and the second channel 202 can be effectively avoided, and the sealing performance and the stability in the air flow circulation process can be further improved. The performance of the drying apparatus 2 is effectively improved.

Optionally, the partition 211 is in an arc sheet shape extending in a direction surrounding the first direction changing member 22, the partition 211, both side edges of the first port 203, and both side edges of the second port 204 are located on the same cylindrical surface, and the first direction changing member 22 is configured to rotate around an axis of the cylindrical surface.

Wherein the first reversing element 22 is in a first state: the first baffle 222 extends from a side edge of the first port 203 to the first end of the partition 211, and optionally, in the process that the first baffle 222 extends from a side of the first port 203 to the first end of the partition 211, the first baffle 222 is inclined with respect to the flow direction of the first port 203 and/or the flow direction of the first end of the first channel 201, that is, the guiding of the airflow may be achieved by the first baffle 222 forming a guiding structure; the second baffle 223 extends from one side edge of the second port 204 to the second end of the partition 211, and optionally, in the process that the second baffle 223 extends from one side edge of the second port 204 to the second end of the partition 211, the second baffle 223 is inclined with respect to the flow direction of the second port 204 and/or the flow direction of the first end of the second channel 202, that is, the guiding structure formed by the second baffle 223 can guide the airflow.

Wherein the first reversing element 22 is in the second state: the first baffle 222 extends from the other side edge of the first port 203 to the second end of the partition 211, and optionally, in the process that the first baffle 222 extends from the other side of the first port 203 to the second end of the partition 211, the first baffle 222 is inclined with respect to the flow direction of the first port 203 and/or the flow direction of the first end of the second channel 202, that is, the guiding of the airflow can be realized by the first baffle 222 forming a guiding structure; the second baffle 223 extends from the other side edge of the second port 204 to the first end of the partition 211, and optionally, in the process that the second baffle 223 extends from the other side edge of the second port 204 to the first end of the partition 211, the second baffle 223 is inclined with respect to the flow direction of the second port 204 and/or the flow direction of the first end of the first channel 201, that is, the guiding structure formed by the second baffle 223 can guide the airflow.

In addition, in these cases, the first baffle 222 is aligned with the first port 203 and the second baffle 223 is aligned with the second port 204.

Optionally, in combination with the foregoing embodiment, the first baffle 222 and the second baffle 223 both extend along the diameter direction of the foregoing cylindrical surface.

With reference to fig. 3 to 18, in some embodiments, the drying device 2 further comprises: a second direction change member 23, the second direction change member 23 having a third state and a fourth state. Referring to fig. 3 to 6 and 15 to 18, the second direction-changing member 23 connects the third port 205 and the second end of the first channel 201 in the third state and connects the fourth port 206 and the second end of the second channel 202, and referring to fig. 7 to 14, the second direction-changing member 23 connects the third port 205 and the second end of the second channel 202 and connects the fourth port 206 and the second end of the first channel 201 in the fourth state.

In addition, it should be noted that the second direction-changing member 23 may have a third state and a fourth state, which does not mean that the second direction-changing member 23 only has the third state and the fourth state, and the second direction-changing member 23 may also have a third state or more, for example, all of the third interface 205, the fourth interface 206, the first channel 201 and the second channel 202 are turned on.

Taking the third port 205 and the fourth port 206 as air flow outlets for drying air, air flows are sent out through the third port 205 and the fourth port 206, and air flows in the first channel 201 and the second channel 202 are sent out through the third port 205 and the fourth port 206. For this example, the third port 205 may communicate with an inner space of the washing apparatus, and the fourth port 206 may communicate with an outer space of the washing apparatus. The purpose of changing the air outlet direction of the drying equipment is achieved through the switching of the second reversing piece 23.
