Description

Technical Field

[0001] The present disclosure relates to the technical field of laundry treatment equipment, and particularly to a condensation tray and a washing machine having the condensation tray. Background Art

[0002] With the continuous improvement of the material living standard, laundry treatment equipment with a drying function is increasingly favored. Its principle is to use high-temperature drying gas to pass through wet laundry, so that the moisture on the laundry evaporates. In this process, the drying gas becomes high-humidity gas, and the high-humidity gas needs to be dried before entering the drying air duct. Specifically, the high-temperature and high-humidity gas is brought into contact with a condensation tray at a lower temperature to precipitate condensed water. Therefore, whether it can achieve sufficient and effective heat exchange with the high-temperature and high-humidity gas becomes the key to the design of the condensation tray. Summary of the Utility Model

[0021] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0022] The embodiments described in some embodiments of the present disclosure below do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0023] It should be noted that all actions of obtaining signals, information, or data in the present disclosure are carried out on the premise of complying with the corresponding data protection regulations and policies of the country where it is located and obtaining authorization from the owner of the corresponding device.

[0024] As Figure 1 and Figure 2 shown, an exemplary embodiment of the present disclosure provides a condensation tray 5300, which is applicable to laundry treatment equipment, including but not limited to an integrated washing machine with a drying function or a dryer, etc. The condensation tray 5300 provided by the present disclosure is adapted to form a closed chamber 5340 with the bottom of the outer tub of the washing machine, and a cooling medium at a lower temperature can flow in the chamber 5340.

[0025] Taking an integrated washing machine with a drying function as an example, generally speaking, it includes an outer tub and an inner tub, and the outer tub plays a role of accommodating and supporting the inner tub. The condensation tray 5300 is disposed between the bottom of the inner tub and the bottom of the outer tub. The high-temperature and high-humidity gas discharged from the inner tub becomes dry after heat exchange with the condensation tray 5300 due to the precipitation of condensed water. The dry gas therein is heated by the drying air duct and then returns to the inner tub again, while the precipitated condensed water is discharged from the water outlet at the bottom of the outer tub.

[0026] Specifically, the condensation tray 5300 includes a tray body 5310. A flow channel 5320 for the circulation of a cooling medium is provided on one side of the tray body 5310 facing the bottom of the outer tub of the washing machine. The flow channel 5320 is configured such that the cooling medium can at least flow circumferentially within the chamber 5340, fill the chamber 5340, and then be discharged from the chamber 5340. The condensation tray 5300 can be made of a metal material, for example, so as to have good heat conduction performance. The flow channel 5320 is provided on one side of the condensation tray 5300 facing the bottom of the outer tub, and the side of the condensation tray 5300 facing the bottom of the inner tub serves as a contact surface for heat exchange with the high-temperature and high-humidity gas.

[0027] The flow channel 5320 will determine the flow trajectory of the cooling medium within the chamber 5340. In this way, by making the flow channel at least have a portion surrounding the tray body 5310, the cooling medium entering the chamber 5340 can flow circumferentially. Considering that the cooling medium has a circumferential flow trajectory, compared with other flow trajectories such as radially divergent ones, the circumferential flow trajectory can extend the flow time of the cooling medium within the chamber, and the longer flow time is further conducive to enabling the high-temperature and high-humidity gas to fully exchange heat with the condensation tray, improving the heat exchange efficiency.

[0028] In addition, the gas after the drying process needs to be heated in the drying air duct and then returned to the inner tub. Therefore, the more dry gas enters the drying air duct, the more conducive it is to improving the drying efficiency. And since the condensation tray 5300 provided in the present disclosure has the flow channel 5320 configured such that the cooling medium can flow circumferentially within the chamber 5340, the heat exchange efficiency is improved, which further increases the intake volume of the dry gas entering the drying air duct and enhances the drying efficiency.

[0029] The technical solution provided by the embodiment of the present disclosure may include the following beneficial effects: A flow channel 5320 is provided on one side of the condensation tray 5300 of the present disclosure facing the cylinder body of the outer tub of the washing machine. The flow channel 5320 is configured such that the cooling medium can flow circumferentially within the chamber 5340 between the condensation tray 5300 and the bottom of the outer tub. That is, through reasonable design of the flow channel 5320 in the condensation tray of the present disclosure, the flow trajectory of the low-temperature cooling medium within the chamber is to flow circumferentially around the condensation tray 5300 and can fill the chamber 5340. This is conducive to increasing the contact area between the low-temperature cooling medium and the tray body 5310, thereby extending the flow time of the cooling medium within the chamber 5340. Further, it is conducive to enabling the high-temperature and high-humidity gas in the inner tub to fully exchange heat with the condensation tray 5300, improving the heat exchange efficiency, which can further increase the intake volume of the dry gas entering the drying air duct, thereby enhancing the drying efficiency.

[0030] Such as Figure 1 and Figure 2As shown, the condensation tray 5300 may further include a plurality of seals 5330 fixedly provided on the tray body 5310. The seals 5330 may be, for example, sealing rubber rings or sealing rubber strips. The plurality of seals 5330 are sealingly abutted against the bottom of the outer tub of the washing machine to form a flow channel 5320. On the one hand, due to its good plasticity, the seal 5330 can more easily define the required flow path. On the other hand, its good sealing performance is also beneficial to avoid the overflow of the cooling medium.

[0031] In some embodiments, as Figure 1 shown, an embodiment is provided that can enable the cooling medium to flow circumferentially in the chamber 5340. Specifically, the seal 5330 may include a first seal 5331 and a second seal 5332 respectively configured as rings. The second seal 5332 is sleeved on the outer periphery of the first seal 5331, wherein the second seal 5332 is provided with an opening 5333. The flow channel 5320 includes a first flow channel 5321 formed between the first seal 5331 and the second seal 5332 and a second flow channel 5322 formed between the second seal 5332 and the outer peripheral edge of the tray body 5310.

[0032] Among them, the second seal 5332 is provided with an opening 5333 to communicate the first flow path 5321 and the second flow path 5322, specifically as Figure 2 shown by the arrow direction in the figure. The solid arrow shows that the cooling medium enters the first flow channel 5321 through the water inlet of the chamber 5340, and then enters the second flow channel 5322 from the first flow channel 5321. Since the second flow channel 5322 is defined between the annular second seal 5332 and the outer peripheral edge of the tray body 5310, for example, an annular seal is also provided on the outer peripheral edge of the tray body 5310, which enables the cooling medium shown by the dashed arrow to flow circumferentially in the second flow channel 5322, and as the cooling medium is continuously injected, the entire chamber 5340 will be filled.

[0033] In some embodiments, continuing to refer to Figure 1 the figure, the opening 5333 may be provided at the bottom of the second seal 5332, and the water outlet 5341 of the chamber 5340 is provided at the top of the outer tub of the washing machine. It should be noted that the top and bottom here are referenced based on the normal use state of the washing machine. In the normal use state of the washing machine, the outer tub and the condensation tray 5300 remain stationary, while the inner tub can rotate. As Figure 2As shown by the arrow, the cooling medium enters the second flow channel 5322 from the opening 5333 at the bottom of the second seal 5332. Since the water outlet 5341 of the chamber 5340 is located at the top of the outer tub of the washing machine, the cooling medium needs to flow around from the bottom in order to be discharged from the water outlet 5341 at the top. That is, by reasonably setting the positions of the opening 5333 and the water outlet 5341, the flow direction of the cooling medium in the second flow channel 5322 can be guided, so as to achieve the purpose of enabling the cooling medium to flow circumferentially in the chamber 5340.

[0034] Optionally, as Figure 1 and Figure 2 shown, the water inlet of the chamber 5340 is located at the top of the outer tub of the washing machine, and there are two water outlets 5341 of the chamber 5340, which are respectively located on both sides of the water inlet, so as to form two second flow channels 5322 extending respectively to the left and right from the opening 5333. This way of the cooling medium flowing from both sides respectively makes the distribution of the cooling medium more uniform, that is, the flow distances on both sides are close or equal. This uniform distribution is compared with the non-uniform way in which only one water outlet 5341 is provided on one side, resulting in a longer time for the other side to be filled with the cooling medium.

[0035] In addition, the top of the second seal 5332 can protrude in a direction away from the first seal 5331 to form a buffer chamber 5334 between the first seal 5331 and the second seal 5332. The buffer chamber 5334 is communicated with the first flow channel 5321, and the cavity area of the buffer chamber 5334 is larger than the area of the first flow channel 5321. Since the first flow channel 5321 is relatively narrow, the provision of the buffer chamber 5334 is conducive to avoiding the function of storing and buffering when the water flow rate at the water inlet is large, and avoiding the cooling medium with a large water flow rate directly impacting the narrow first flow channel 5321, causing deformation of the first seal 5331 and the second seal 5332 and affecting the sealing performance.

[0036] According to the second aspect of the embodiments of the present disclosure, there is also provided a washing machine, which includes the condensate tray of any one of the above, and has all its beneficial effects, which will not be elaborated here.

[0037] In some embodiments, the washing machine further includes an outer tub of the washing machine. The condensate tray 5300 further includes a plurality of seals 5330 fixedly arranged on the tray body 5310. The plurality of seals 5330 are hermetically abutted against the bottom of the outer tub of the washing machine to form a flow channel 5320. The bottom of the outer tub of the washing machine is provided with ribs corresponding to the seals 5330, and the seals 5330 are in interference fit with the ribs. The ribs can, on the one hand, play a role in strengthening the structural strength of the condensate tray 5300, and on the other hand, can play a role in reliably supporting the seals 5330 due to the interference fit with the seals 5330.

[0038] In some other embodiments, the washing machine may further include an inner drum of the washing machine, and the condensation tray 5300 is disposed between the inner drum of the washing machine and the outer drum of the washing machine, so that the high-temperature and humid gas in the inner drum of the washing machine can be exchanged heat with the condensation tray 5300 to form a low-temperature and dry gas.
