Description

Technical Field

[0001] The present invention relates to the technical field of dryers, and in particular to a bracket, a dryer and a drying control method. Background Art

[0002] A dryer uses heating, air circulation, and moisture removal to dry wet clothes and other items. The dryer features a rotating drum, with the item being placed directly inside the drum and rotating with it.

[0003] Dryers in the prior art generally have a humidity sensor installed on the side wall of the drum. The load to be dried in the drum contacts two metal bars of the humidity sensor as it rolls. Since the load to be dried contains a certain amount of moisture, the humidity sensor can detect the resistance value of the load to be dried when it contacts the metal bars. The control system then determines the dryness of the load to be dried based on the resistance.

[0004] The prior art also provides a technical solution for installing a bracket in a dryer. This bracket is used to support loads that need to be dried but cannot easily rotate with the inner drum, such as shoes and underwear. However, if the bracket is used to support the load to be dried, the load to be dried cannot directly contact the side wall of the drum. Therefore, the technical solution of installing a humidity sensor on the side wall of the drum cannot determine the humidity of the load on the bracket.

[0040] This embodiment provides a rack and a dryer. The dryer includes a drying chamber, a heating device, and an air circulation device. The heating device is configured to increase the temperature of the drying chamber, and the air circulation device is configured to exchange air within the drying chamber with external air. The dryer also includes the rack provided in this embodiment, which is disposed within the drying chamber and configured to accommodate a load to be dried. In this embodiment, the load to be dried may include wet clothing, bedding, and the like.

[0041] Figure 1 Schematic diagram of the structure of the bracket provided by the embodiment of the present invention is shown. Figure 1 The bracket provided in this embodiment includes a first frame 100, a second frame 200, and a humidity judgment circuit 300. The first frame 100 and the second frame 200 are insulated and electrically connected to the humidity judgment circuit 300. The load to be dried is carried on the first frame 100 and the second frame 200 to connect to the humidity judgment circuit 300, and the humidity judgment circuit 300 can determine the humidity of the load to be dried. In other words, the humidity judgment circuit 300 can be connected to the load to be dried placed on the first frame 100 and the second frame 200, and the humidity judgment circuit 300 determines the humidity of the load to be dried by detecting the resistance of the load to be dried.

[0042] Figure 2 The schematic diagram of the partial structure of the bracket provided by the embodiment of the present invention is shown as an upward angle. Figure 1 and Figure 2, the bracket also includes an insulating connection structure 400. The insulating connection structure 400 includes a carrier 410 and a plurality of connectors 420. The carrier 410 is a long plate-like structure, and a plurality of connectors 420 are arranged at intervals on one side of the carrier 410 along the extension direction of the carrier 410. In this embodiment, in order to improve the connection strength between the connector 420 and the carrier 410, the connector 420 and the carrier 410 are made of an integral molding method. The carrier 410 and the connector 420 are both made of insulating materials such as plastic. The first frame 100 includes a first carrier part 110, and the second frame 200 includes a second carrier part 210. The first carrier part 110 and the second carrier part 210 are respectively located on both sides of the carrier 410 in the width direction, and are respectively connected to the connector 420.

[0043] Specifically, the connecting member 420 is a hollow cylindrical structure with a through hole provided along its central axis. At the middle position of the through hole, a partition is provided in a direction perpendicular to the central axis of the through hole to divide the space in the through hole into a first insertion space and a second insertion space that are isolated from each other. The first bearing portion 110 includes a plurality of first support rods that are parallel to each other and spaced apart along the extension direction of the bearing member 410. The end of the first support rod can be inserted into the first insertion space of the through hole from one end of the connecting member 420. Similarly, the second bearing portion 210 includes a plurality of second support rods that are parallel to each other and spaced apart along the extension direction of the bearing member 410. The end of the second support rod can be inserted into the second insertion space of the through hole from the other end of the connecting member 420. Through the above arrangement, the first frame 100 and the second frame 200 can be connected through the insulating connection structure 400, and the insulating connection structure 400 can ensure insulation between the first frame 100 and the second frame 200.

[0044] More specifically, in another embodiment, a plurality of first connection holes and a plurality of second connection holes are respectively defined on opposite sides of the first supporting portion 110 and the second supporting portion 210. In other words, each first support rod has a first connection hole defined at its end, and each second support rod has a second connection hole defined at its end. The connecting member 420 is a rod-shaped structure, and its two ends can be inserted into the first connection hole and the second connection hole, respectively, to connect the first frame 100 and the second frame 200 to the insulating connection structure 400.

[0045] Figure 3 A partial schematic diagram of an insulating joint provided by an embodiment of the present invention is shown. Figure 1 and Figure 3, the bracket also includes an insulating joint 500. The insulating joint 500 and the insulating connection structure 400 are spaced apart along the central axis of the bracket. The first frame 100 also includes a first connecting rod 120, and the second frame 200 also includes a second connecting rod 220. The first connecting rod 120 is connected to the first bearing part 110, and the second connecting rod 220 is connected to the second bearing part 210. The first connecting rod 120 and the second connecting rod 220 can be connected to the insulating joint 500 respectively. In other words, through the above arrangement, the insulating joint 500 can further improve the connection stability of the first frame 100 and the second frame 200 and the overall structural reliability of the bracket on the basis of the insulating connection structure 400. In this embodiment, the insulating joint 500 can be made of insulating materials such as plastic.

[0046] Specifically, the insulating joint 500 includes a snap-fit base 510 and a joint cover 520. A first snap-fitting slot 511 and a second snap-fitting slot 512 are spaced apart in the snap-fit base 510. The end of the first connecting rod 120 is bent to form a first snap-fitting end, and the end of the second connecting rod 220 is bent to form a second snap-fitting end. The first snap-fitting end and the second snap-fitting end are respectively embedded in the first snap-fitting slot 511 and the second snap-fitting end. The joint cover 520 is mounted on the snap-fit base 510 to seal the first snap-fitting end and the second snap-fitting end.

[0047] Preferably, the bracket further includes a reminder device and a pressure sensor. The pressure sensor is disposed on the first frame 100 and the second frame 200, is communicatively connected to the reminder device, and is configured to detect the weight of the load on the first frame 100 and the second frame 200. When the weight of the load on one of the first frame 100 and the second frame 200 is zero, it indicates that the bracket is carrying a load to be dried, but the load to be dried is not simultaneously contacting the first frame 100 and the second frame 200. Therefore, the humidity determination circuit 300 cannot be connected, and the humidity determination of the load to be dried cannot be performed. Therefore, the reminder device issues an alarm to remind the user to place the load to be dried. In this embodiment, the reminder device can be a buzzer or a warning light, etc., whichever is capable of reminding the user. The specific form is not limited in this embodiment.

[0048] Continue to refer to Figure 1 The bracket also includes a sensor bracket 600. The sensor bracket 600 includes a mounting bracket. The humidity determination circuit 300 includes a sensor metal strip 310 embedded in the mounting bracket and capable of detecting the resistance of the load to be dried. One end of the first frame 100 and one end of the second frame 200 are respectively embedded in pre-set mounting slots connected to the mounting bracket and are electrically connected to the sensor metal strip 310 via wires 320.

[0049] Specifically, in this embodiment, the sensor bracket 600 further includes a first connector 610 and a second connector 620. The first connector 610 and the second connector 620 are spaced apart along the width of the mounting frame and are integrally formed with the mounting frame. The first connector 610 and the second connector 620 each have a hollow cylindrical structure, with both openings facing upward. The first frame 100 further includes a first conductive rod 130, which is a curved rod-shaped structure integrally formed on the side of the first bearing portion 110 away from the first connecting rod 120 and can be inserted into the first connector 610. Similarly, the second frame 200 includes a second conductive rod 230, which is a curved rod-shaped structure integrally formed on the side of the second bearing portion 210 away from the second connecting rod 220 and can be inserted into the second connector 620. In other words, the sensor bracket 600 further stabilizes the connection between the first frame 100 and the second frame 200.

[0050] More specifically, conductive contact pieces are provided at the bottom of each of the first and second connectors 610, 620. These contact pieces are electrically connected to the sensor metal strip 310 via the wire 320. When the first conductive rod 130 is inserted into the first connector 610 and the second conductive rod 230 is inserted into the second connector 620, they can connect to the two conductive contact pieces, respectively, and thus achieve electrical connection to the sensor metal strip 310 via the wire 320. The provision of these conductive contact pieces can save wiring steps between the first conductive rod 130 and the sensor metal strip 310, and between the second conductive rod 230 and the sensor metal strip 310, thereby improving the assembly efficiency of the bracket. Moreover, the connection points only exist between the wire 320 and the bottom of the first connector 610, and between the wire 320 and the bottom of the second connector 620, which is more stable and reliable. It avoids the problem of loose connection points caused by the first frame 100 and the second frame 200 needing to frequently withstand the pressure of the load to be dried when the connection points are directly set between the wire 320 and the first conductive rod 130, and between the wire 320 and the second conductive rod 230.

[0051] This embodiment also provides a drying control method. The drying machine provided in this embodiment can be controlled using the drying control method. The drying control method includes:

[0052] Step S10: placing the load to be dried on the bracket.

[0053] In order to turn on the humidity determination circuit 300 , step S20 needs to be performed to ensure that the load to be dried contacts the first frame 100 and the second frame 200 at the same time.

[0054] Step S20: If the load weight of one of the first frame 100 and the second frame 200 is zero, the reminder device sounds an alarm and the user should adjust the placement of the load to be dried. Otherwise, the humidity determination circuit 300 is determined to be on.

[0055] In step S30, when the resistance value of the load to be dried reaches a first preset value A, indicating that the load to be dried is close to being dried, the heating device is controlled to reduce the heating power and the air circulation device is controlled to reduce the air circulation speed. This can also achieve the purpose of continuing to dry the load to be dried, thereby achieving energy conservation. The first preset value A can be selected based on actual conditions, and this embodiment does not limit its specific value.

[0056] Step S40: When the resistance value of the load to be dried reaches the second preset value B, it means that the load to be dried has been dried. At this time, the humidity judgment circuit 300 is disconnected, the heating device stops heating, and the air circulation device stops air circulation. The second preset value B is greater than the first preset value A.

[0057] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
