In addition, the terms "first", "second", "third", and "fourth" are only used for descriptive purposes. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

At present, the most common washing machines are mainly divided into three categories: (1) pulsator washing machines, which have the advantages of energy saving, short washing time, high cleaning rate, easy operation, simple and convenient cleaning, easy to move, and low price; (2) drum washing machines, which have the advantages of water saving, less wear and tear on clothes, multiple functions, beautiful appearance, and small space. Among them, many drum clothing processing equipment has three-in-one functions, namely washing, dehydration, and drying, which can complete the whole process from washing to drying in one go, eliminating the trouble of taking clothes out and then drying or hanging clothes; (3) agitator washing machines, which have the strongest cleaning power for clothes, but are more destructive and noisy than the first two methods.

As people's requirements for quality of life continue to improve, drum washing machines are equipped with steam drying functions. This drying function achieves the purpose of drying clothes by increasing the temperature. The washing machine sprays constant steam on the clothes to achieve the purpose of drying clothes. When the washing machine stretches the clothes, it will perform constant temperature condensation drying on the clothes. This drying method can not only speed up the drying of heavy clothes, but also play a stretching and ironing effect on the clothes.

Generally speaking, washing machines with drying functions are divided into the following types: (1) direct-discharge drying washing machines with integrated drying function. The working principle of the direct-discharge type is that the air is heated by the heater, heats the clothes, and becomes humid hot air and is discharged to the outside, forming a cycle, which continuously removes the moisture from the clothes to achieve the purpose of drying the clothes; (2) condensing drying washing machines with integrated drying function. The working principle of the condensing type is that the air is heated by the heater, enters the drum to heat the clothes, and becomes humid hot air in the drum, and then passes through the condensation system to condense the moisture into water and collect it in the water storage box, forming a cycle, which continuously removes the moisture from the clothes to achieve the purpose of drying the clothes. (3) Steam drying washing machine: The washing machine sprays constant steam on the clothes to dry the clothes. After the clothes are spread out, the clothes are dried by constant temperature condensation. (4) Waterless condensation drying washing machine: The washing machine simulates and realizes atmospheric circulation by using internal temperature, flowing air, time, etc., and then uses the exchange of cold and hot air flows formed in the atmospheric circulation to dry the clothes. The temperature inside the washing machine will become low, causing the moisture on the clothes to turn into water, and the water will be discharged through the drain pipe.

However, in the prior art, washing machines with drying function are mainly the above-mentioned condensing drying washing and drying machines. When steam is sprayed on clothes to dry them, the hot and humid gas in the washing machine drum is difficult to be discharged, and the exchange of cold and hot air flows is slow, resulting in low drying efficiency of clothes.

First, refer to FIG. 1, which is a schematic diagram of the overall structure of a preferred embodiment of a washing machine with a drying function provided by the present invention. As shown in FIG. 1, the present invention provides a washing machine with a drying function, the washing machine includes a barrel 1 and a ventilation mechanism 2, the ventilation mechanism 2 connects the barrel 1 and the external environment, and the ventilation mechanism 2 includes a diverter valve 21, and the diverter valve 21 is configured to adjust the gas flow rate of the ventilation mechanism 2. When the washing machine enters the drying function, the diverter valve 21 is opened to accelerate the gas flow rate of the ventilation mechanism 2, thereby accelerating the gas circulation between the barrel 1, the ventilation structure 2 and the external environment, which is conducive to discharging a large amount of hot and humid gas inside the barrel 1, thereby improving the drying efficiency. In this preferred embodiment, the washing machine also includes a drying fan (not shown in the figure), the drying fan is fixed inside the barrel 1, and the drying fan is configured to realize the drying function of the washing machine. The drying fan can increase the temperature inside the barrel 1 and accelerate the gas flow inside the barrel 1, thereby further improving the drying efficiency of the washing machine. It should be noted that the present invention does not impose any restrictions on the specific setting position of the drying fan, and those skilled in the art can set it according to actual use requirements.

In a first possible implementation, a humidity sensor and a controller are provided inside the drum 1. The controller is connected to the humidity sensor and the diverter valve 21 by signals respectively. The controller is configured to control the diverter valve 21 to open in response to the detection value of the humidity sensor reaching a first humidity threshold value during the drying process. The controller is also configured to control the diverter valve 21 to close in response to the detection value of the humidity sensor reaching a second humidity threshold value during the drying process. The humidity value inside the drum 1 is detected by the humidity sensor, and the drying intensity required by the washing machine can be determined. When the humidity value is large, it means that there are more clothes to be dried inside the drum 1, and the drying intensity required by the washing machine is large. The controller controls the diverter valve 21 to open, thereby accelerating the flow of gas. When the humidity sensor detects that the humidity value inside the drum 1 is small, the drying intensity required by the washing machine is small, and the controller controls the diverter valve 21 to close, so as to block the flow of gas between the drum 1 and the external environment, and dry the clothes through the high-temperature gas inside the drum 1.

It should be noted that the present invention does not impose any restrictions on the specific types and locations of the humidity sensor and the controller, and those skilled in the art can set them according to actual use requirements. For example, the humidity sensor is set inside the cylinder 1 and rotates with the cylinder 1, and the controller is set on the upper part of the cylinder 1, and the two maintain signal communication. In addition, although the opening and closing state of the diverter valve 21 is controlled by the first humidity threshold and the second humidity threshold in this preferred embodiment, this is not restrictive. In some embodiments, the humidity sensor can be set with multiple humidity thresholds to control different openings of the diverter valve 21. Those skilled in the art can set the remaining embodiments according to actual conditions.

In a second possible implementation, a temperature sensor and a controller are provided inside the drum 1, and the controller is respectively connected to the temperature sensor and the diverter valve 21 by signal. The controller is configured to control the diverter valve 21 to open when the detection value of the temperature sensor reaches a first temperature threshold value during the drying process, and the controller is also configured to control the diverter valve 21 to close when the detection value of the temperature sensor reaches a second humidity threshold value during the drying process. The temperature sensor detects the temperature value inside the drum 1, and the drying intensity required by the washing machine can be determined. When the temperature value is large, it means that there is more humid and hot gas in the drum 1, and the controller controls the diverter valve 21 to open, thereby accelerating the flow of gas. When the temperature sensor detects that the temperature value inside the drum 1 is small, the controller controls the diverter valve 21 to close, so as to block the flow of gas between the drum 1 and the external environment, and dry the machine with the high-temperature gas inside the drum 1.

It should be noted that the present invention does not impose any restrictions on the specific types and installation positions of the temperature sensor and the controller. Those skilled in the art can set them according to actual use requirements. For example, the temperature sensor is set inside the drum 1 and rotates with the drum 1. The controller is set on the upper part of the drum 1, and the two maintain signal communication. In addition, although the opening and closing state of the diverter valve 21 is controlled by the first temperature threshold and the second temperature threshold in this preferred embodiment, this is not restrictive. In some embodiments, the temperature sensor can also be used to measure the body temperature of the washing machine. When the body temperature is too high, the opening of the diverter valve 21 is increased to achieve cooling of the washing machine. The remaining embodiments can be set by those skilled in the art according to actual conditions.

In a third possible implementation, a pressure sensor and a controller are provided inside the drum 1, and the controller is respectively connected to the pressure sensor and the diverter valve 21 by signal, and the controller is configured to control the diverter valve 21 to open in response to the detection value of the pressure sensor reaching the pressure threshold during the drying process. By detecting the pressure value inside the drum 1 by the pressure sensor, the weight of the clothes to be dried inside the drum 1 can be determined, and then the drying intensity required by the washing machine can be determined. When the pressure value is large, it means that there are more clothes to be dried inside the drum 1, and the drying intensity required by the washing machine is large. The controller controls the diverter valve 21 to open, thereby accelerating the flow of gas.

It should be noted that the present invention does not impose any restrictions on the specific types and installation positions of the pressure sensor and the controller. Those skilled in the art can set them according to actual use requirements. For example, the pressure sensor is set inside the cylinder 1 and rotates with the cylinder 1. The controller is set on the upper part of the cylinder 1, and the two maintain signal communication. In addition, although the opening and closing state of the diverter valve 21 is controlled by the pressure threshold in the preferred embodiment, this is not restrictive. In some embodiments, the user can preset a variety of clothing materials and control the opening value of the diverter valve 21 according to the clothing material and the pressure threshold to avoid deformation of the clothing. For example, the user can preset the clothing material to be wool, pure cotton, polyester, chiffon, etc. When the user chooses to dry wool clothing, the opening of the diverter valve 21 is controlled to be smaller to avoid damage to the clothing. The remaining embodiments can be set by those skilled in the art according to actual conditions.

In the above-mentioned multiple embodiments, those skilled in the art can understand that the present invention does not impose any limitation on the specific structure and model of the controller, and the controller can be either the original controller of the washing machine or a controller separately provided for executing the control method of the present invention. The signal connection between the controller and the humidity sensor and the diverter valve 21 can be a digital signal or a Bluetooth signal, and the technicians can set the structure and model of the controller according to actual usage requirements.

In some embodiments, the diverter valve 21 may be provided with a plurality of adjustment gears to adjust the gas in the ventilation mechanism 2 to produce different gas flow rates. For example, the diverter valve 21 is provided with a first gear and a second gear of gas flow rate from high to low. Taking the first implementation mode of setting a humidity sensor as an example, in response to the detection value of the humidity sensor reaching the first humidity threshold, the diverter valve 21 is controlled to open to the first gear, and in response to the detection value of the humidity sensor decreasing to the low humidity threshold, the diverter valve 21 is controlled to open to the second gear. In addition, the technical solutions of setting a temperature sensor and setting a pressure sensor are similar to the above implementation mode, and will not be repeated here.

It should be noted that the present invention does not impose any limitation on the above-mentioned implementation method and its superposition method. Those skilled in the art can set it according to actual use requirements. For example, a temperature sensor and a humidity sensor can be set in the cylinder 1 at the same time, and the detection values of the two can be combined to control the opening and closing state of the diversion valve 21.

In a preferred embodiment, the controller is connected to the drying fan signal, and the controller is configured to be able to adjust the drying fan to a high gear in response to the opening of the diverter valve 21, and the controller is configured to be able to adjust the drying fan to a low gear in response to the closing of the diverter valve 21. The drying state in the drum 1 is determined by the opening and closing state of the diverter valve 21. When the diverter valve 21 is opened, it means that the drying intensity in the drum 1 is relatively large. At this time, adjusting the drying fan to a high gear can further speed up the drying efficiency; when the diverter valve 21 is closed, it means that the drying intensity in the drum 1 is relatively small. At this time, adjusting the drying fan to a low gear can avoid damaging the clothes.

In a preferred embodiment, the ventilation mechanism 2 also includes an air inlet pipeline 22 and an air outlet pipeline 23, and the air inlet pipeline 22 and the air outlet pipeline 23 are both connected to the cylinder 1 and the external environment. It can be understood that in the circulation process of the gas, the gas enters the interior of the cylinder 1 from the external environment through the air inlet pipeline 22, and after drying, the hot and humid gas inside the cylinder 1 is discharged to the external environment through the air outlet pipeline 23, thereby realizing gas circulation. In this preferred embodiment, the guide valve 21 is arranged on the air inlet pipeline 22 and/or the air outlet pipeline 23. By arranging the guide valve 21 on the air inlet pipeline 22 and/or the air outlet pipeline 23, the gas flow of the air inlet pipeline 22 and/or the air outlet pipeline 23 can be accelerated, thereby accelerating the gas circulation between the cylinder 1, the ventilation structure 2 and the external environment. It should be noted that the present invention does not impose any restrictions on the specific setting position of the guide valve 21, and those skilled in the art can set it according to actual use requirements. In addition, it is understandable that when the guide valve 21 is provided on both the air inlet pipe 22 and the air outlet pipe 23, the gas flow rate can be further accelerated, but the cost is relatively high, and technicians in this field can set it according to actual usage requirements.

To sum up, when the above-mentioned technical scheme is adopted, when the washing machine with drying function provided by the present invention enters the drying function, the guide valve 21 is opened, which can accelerate the gas flow rate of the ventilation mechanism 2, and then accelerate the gas circulation between the drum 1, the ventilation structure 2 and the external environment, which is beneficial to discharge a large amount of humid and hot gas inside the drum 1, thereby improving the drying efficiency.

So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
