Embodiment one

This embodiment provides a laundry processing device with a drying function, which includes a box body 10 and a drum 20 rotatably arranged in the box body 10 . The axis of the drum 20 generally extends along the front-rear direction, so that one axial end (hereinafter referred to as the front end) of the drum 20 is disposed toward the user, and the other end (hereinafter referred to as the rear end) is disposed away from the user. The user puts the clothes to be dried into the drum 20 through the opening at the front end of the drum 20, and the air duct assembly is arranged in the box body 10, and the air duct assembly is used to ventilate the drum 20 so as to contact the clothes through the air flow to achieve air drying or drying. The function of drying clothes.

In the current clothes processing equipment, the air duct assembly generally ventilates into the drum 20 through the rear end of the drum 20, and then the front end of the drum 20 blows air to form a circulating air path, so as to dry or dry the clothes. The air flow in this arrangement flows from back to front in the drum 20 , and the clothes at the rear of the drum 20 can gain more heat, thereby taking away more water vapor. As the temperature of the airflow decreases gradually and the humidity gradually increases, the clothes at the rear of the drum 20 become overdried and shrink seriously, while the clothes at the front of the drum 20 do not dry well, and eventually the clothes in the drum 20 Dries unevenly and takes too long to dry.

In order to solve the above problems, as shown in Figure 1, the air duct assembly in this embodiment includes a first air inlet pipeline 32 and a second air inlet pipeline 33, the first air inlet pipeline 32 and the axial end of the drum 20 (specifically the front end in this embodiment) communicates, the second air inlet pipeline 33 communicates with the other axial end of the drum 20 (specifically the rear end in this embodiment), and the air duct assembly can pass through the first air inlet pipeline 32 and at least one of the second air intake pipeline 33 ventilates into the drum 20 .

By setting the first air inlet pipeline 32 and the second air inlet pipeline 33, the air duct assembly can realize air intake from the front end of the drum 20, air intake from the rear end of the drum 20, and simultaneous air intake from the front end and rear end of the drum 20. The three working states of air intake are beneficial to improve the uniformity of drying clothes in the drum 20, better improve the drying effect of clothes, ensure the quality of clothes after drying, and avoid serious shrinkage and overdrying problems.

To simplify the structure of the air duct assembly, one end of the second air inlet pipeline 33 communicates with the middle of the first air inlet pipeline 32 , and the other end of the second air inlet pipeline 33 communicates with the rear end of the drum 20 . This kind of arrangement makes a part of the first air inlet pipeline 32 a common pipeline, and the air flow is divided or flow direction switched at the junction of the first air inlet pipeline 32 and the second air inlet pipeline 33, so as to satisfy the above three conditions. switching of working states.

For the convenience of introduction, the first air inlet pipeline 32 is divided into a first air inlet section and a second air inlet section, and the first air inlet section is a common pipeline for the airflow. The second air inlet section communicates with the front end of the drum 20 .

Optionally, the air duct assembly further includes a switching valve 35 through which the first air inlet pipeline 32 is connected to the second air inlet pipeline 33 . Specifically, the switching valve 35 has three valve ports, and the three valve ports are respectively connected with the first air inlet section, the second air inlet section and the second air inlet pipeline 33 . The switching valve 35 has three communication states. As shown in FIG. 2 , the first connection state can connect the first air inlet section and the second air inlet section in the first air inlet pipeline 32 to realize the front air flow of the drum 20 through the first air inlet pipeline 32 . Ventilate the inside of the drum 20 sideways, so that the hot air dries the clothes from front to back, and has a good drying effect on the clothes on the front side of the drum 20; as shown in Figure 3, the second connection state can make the first air intake The first air inlet section in the pipeline 32 communicates with the second air inlet pipeline 33, so as to realize ventilation from the rear side of the drum 20 to the inside of the drum 20 through the second air inlet pipeline 33, so that the hot air flows from the rear to the front. Drying clothes, the drying effect on the clothes located at the rear side of the drum 20 is good; as shown in Figure 4, the third connection state can connect the first air inlet section with the second air inlet section and the second air inlet pipeline at the same time. 33 connections, so as to realize the simultaneous air intake from the front and rear ends of the drum 20, and the collision of the two airflows will form fine turbulent flows, which will be transmitted to the surroundings, fully exchange heat with the clothes, and take away the moisture in the clothes .

Further, the air duct assembly also includes an air outlet pipeline 34 and a heat exchange pipeline 31 . One end of the air outlet pipeline 34 is connected to the drum 20 , and the other end is communicated with one end of the heat exchange pipeline 31 . The other end of the heat exchange pipeline 31 can be respectively connected with the first air inlet pipeline 32 and the second air inlet pipeline 33 . By setting the air outlet pipeline 34 and the heat exchange pipeline 31, the air duct assembly can form a circulating air path, and the wet air flow with water vapor discharged from the drum 20 will exchange heat in the heat exchange pipeline 31 to condense moisture, resulting in a dry air stream.

In this embodiment, the air outlet pipeline 34 , the heat exchange pipeline 31 , the first air inlet pipeline 32 and the second air inlet pipeline 33 are connected in sequence to form a circulation loop.

In order to condense moisture in the airflow discharged from the drum 20 , the laundry treatment device further includes a heat pump assembly 40 and a fan 50 . Both the heat pump assembly 40 and the blower 50 are disposed in the heat exchange pipeline 31 , the heat pump assembly 40 is used to obtain dry air, and the blower 50 is used to drive the airflow in the outlet pipeline 34 to pass through the heat pump assembly 40 . Optionally, the blower 50 is arranged at the front end of the heat pump assembly 40, so as to prevent the blower 50 from being disconnected due to contact with humid air.

Specifically, the heat pump assembly 40 includes an evaporator 41 and a condenser 42 arranged in sequence along the flow direction of the airflow. Wherein, the evaporator 41 is a copper tube fin evaporator, and the condenser 42 is a microchannel condenser. Compared with the combination of copper tube or aluminum tube fin evaporator and copper tube or aluminum tube fin condenser in the prior art, the heat transfer performance of the microchannel condenser is more prominent. When the flow channel size is less than 3mm, the gas-liquid two-phase The law of flow and phase change heat transfer will be different from the conventional larger size, which can effectively enhance the heat transfer efficiency. In addition, the micro-channel condenser is more energy-saving and has low cost. Under the same specification, the cost of the micro-channel condenser is lower than that of the copper tube-fin condenser 42 .

Due to the characteristics of the heat pump assembly 40 itself, its heating time is much slower than that of ordinary heaters, which will greatly affect the drying efficiency. In order to solve the above problems, in this embodiment, heaters are arranged in the first air inlet pipeline 32 and the second air inlet pipeline 33 . Specifically, the heater located in the first air inlet pipeline 32 is specifically arranged in the first air inlet section. The heater located in the first air intake section starts to work simultaneously with the heat pump assembly 40 when the drying program is started, so that the temperature in the drum 20 can quickly reach the temperature required for drying clothes. After the temperature of the heat pump assembly 40 rises and stabilizes, the heater in the first air intake section can be turned off to reduce energy consumption.

When the ambient temperature is low in winter, the heater in the second air inlet pipeline 33 can be activated to compensate for the heat lost during the flow of the airflow to the second air inlet pipeline 33, so as to ensure the drying of the clothes in the drum 20 Effect.

Further, the heater may be a PTC heater. PTC generally refers to semiconductor materials or components with a large positive temperature coefficient, such as positive temperature coefficient thermistors. Compared with resistance wire heaters, PTC heaters have the advantages of higher thermal efficiency, more durability, and most importantly, higher safety performance.

Further, the laundry processing device further includes a detection assembly, which is provided at both ends of the drum 20 in the axial direction, and the detection assembly includes a humidity sensor and/or a temperature sensor. By detecting the ambient humidity and ambient temperature at the front end and the rear end of the drum 20, the drying condition of the clothes can be judged, so as to improve the intelligence of the drying program.

In this embodiment, both the front end and the rear end of the drum 20 are provided with temperature sensors and humidity sensors, so as to make more accurate judgment on the drying degree of the clothes.

Embodiment two

This embodiment provides a method for drying clothes, which can be used in the clothes treatment device in the first embodiment.

As shown in FIG. 5 , after entering the drying program, air is ventilated into the drum 20 from both axial ends of the drum 20 to dry the clothes in the drum 20 . By ventilating the inside of the drum 20 from both ends of the drum 20 successively, the uniformity of drying of the clothes in the drum 20 can be ensured, and the clothes at one end of the inner shaft of the drum 20 can be avoided from being too dry or shrinking, while the clothes at the inner shaft of the drum 20 can be avoided. There is more moisture in the clothes at the other end and the problem is that they are not fully dried.

Optionally, the clothes drying method further includes ventilating the inside of the drum 20 from both axial ends of the drum 20 at the same time, so as to dry the clothes in the drum 20 . When air is ventilated into the drum 20 from both axial ends of the drum 20 at the same time, the two air streams collide to form fine turbulence, which will be transmitted to the surroundings, fully exchange heat with the clothes, and take away the moisture in the clothes .

In this embodiment, the drying of clothes is divided into three stages. In the first stage, the hot air flows from the front end to the rear end of the drum 20 to dry the clothes; in the second stage, the hot air flows from the rear end to the front end of the drum 20 to dry the clothes; The front end and the rear end pass into the drum 20 at the same time to further dry the clothes. The flow directions of the hot air in the first stage and the second stage are opposite, so that the clothes in the drum 20 along the axial direction can be dried more evenly. In the third stage, the fine turbulence generated by airflow hedging is used to fully diffuse the hot air, further improving the uniformity of clothes drying.

In other embodiments, the order of the three stages can be rearranged. For example, the hot air can be introduced from the front and rear ends of the drum 20 at the same time, and then the hot air can be introduced from the front and rear ends of the drum 20 respectively. Alternatively, after the hot air is introduced from one axial end of the drum 20, the hot air is introduced from the front and rear ends of the drum 20 at the same time, and finally the hot air is introduced from the other axial end of the drum 20.

In the prior art, when the clothes are dried, it is generally judged whether the clothes are dried by the temperature difference of the airflow entering and leaving the drum 20 or the humidity detected by the humidity sensor installed in the drum 20. There is a single drying logic, which is prone to drying. The program ends but the clothes are not dried, and the current drying program does not select the drying degree for different clothes materials and different demand scenarios, which affects the user experience.

In order to solve the above problem, in this embodiment, it is judged whether the clothes are dried or not according to the temperature information and the humidity information at both axial ends of the drum 20 . Specifically, the temperature and humidity of the airflow passing through the two ends of the drum 20 in the axial direction are obtained. When the humidity at both axial ends of the drum 20 is less than the preset humidity value and the humidity difference between the axial ends of the drum 20 is less than the preset humidity difference value, it is judged that the drying of the clothes is completed and the drying program ends.

It can be understood that the preset temperature value, the preset temperature difference value, the preset humidity value and the preset humidity difference value can all be set according to actual needs.

In some embodiments, it is possible to judge whether the clothes are dry only based on the temperature information of the airflow at both axial ends of the drum 20 , or judge whether the clothes are dry only based on the humidity information at the two axial ends of the drum 20 .

Further, in the clothes drying method provided in this embodiment, multiple levels of drying levels are set, and each level of drying level corresponds to a preset temperature value, a preset temperature difference value, a preset humidity value, and a preset humidity difference value , in order to control the drying degree of the clothes.

Exemplarily, the drying degree is set to three levels, including the storage level, the wearing level and the hanging level. When the storage file is selected, the preset temperature value is higher, and the preset temperature difference, preset humidity value, and preset humidity difference are all smaller. At this time, the clothes are very dry and are suitable for direct storage after drying.

When choosing the suitable gear, the preset temperature value is lower than the preset temperature value of the storage gear, and the preset temperature difference, preset humidity value, and preset humidity difference are slightly greater than the corresponding values of the storage gear, and the clothes are moderately dry at this time , suitable for immediate wearing after drying.

When the hang-drying file is selected, the preset temperature value is lower than the preset temperature value of the storage file and the wearable file, and the preset temperature difference, preset humidity value, and preset humidity difference are larger than the storage file and the wearable file. The level corresponds to the numerical value. At this time, the dryness of the clothes is poor, and it needs to be hung for a period of time after drying. This level is suitable for silky, wrinkled, and shrinkable clothes.

Apparently, the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, rather than limiting the implementation of the present invention. Various obvious changes, readjustments, and substitutions will occur to those skilled in the art without departing from the scope of the present invention. It is not necessary and impossible to exhaustively list all the implementation manners here. All modifications, equivalent replacements and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the claims of the present invention.
