[0032] Some embodiments of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present invention and are not used to limit the protection scope of the present invention. Those skilled in the art can adjust them as needed to adapt to specific application scenarios.

[0034] In addition, it should also be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "linked" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can also be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0035] Based on the problem pointed out in the background art that the peculiar smell in the washing machine in the prior art is not easy to dissipate, the present invention provides a fresh air component and a laundry treatment device, aiming to make the gas inside the air exchange cavity flow unidirectionally to the outside of the air exchange cavity through the exhaust structure, and the gas outside the air exchange cavity flow unidirectionally to the inside of the air exchange cavity through the intake structure by setting the first Tesla valve and the second Tesla valve. At the same time, due to the acceleration effect of the Tesla valve on the gas flowing in the positive direction therein, a natural circulation can be realized even with a small pressure difference inside and outside the air exchange cavity, improving the air exchange effect. When there is a peculiar smell in the air exchange cavity, the dissipation of the peculiar smell can be effectively accelerated.

[0036] The fresh air component of the present invention includes an air exchange cavity, an exhaust structure, and an intake structure. An air exchange chamber is formed inside the air exchange cavity; the exhaust structure is communicated with the air exchange chamber, and the exhaust structure is provided with a first Tesla valve, and the first Tesla valve is arranged to enable the gas to flow from the inside of the air exchange cavity to the outside of the air exchange cavity; the intake structure is communicated with the air exchange chamber, and the intake structure is provided with a second Tesla valve, and the second Tesla valve is arranged to enable the gas to flow from the outside of the air exchange cavity to the inside of the air exchange cavity. Due to the setting of the first Tesla valve and the second Tesla valve, the gas inside the air exchange cavity flows unidirectionally to the outside of the air exchange cavity through the exhaust structure, and the gas outside the air exchange cavity flows unidirectionally to the inside of the air exchange cavity through the intake structure. At the same time, due to the acceleration effect of the Tesla valve on the gas flowing in the positive direction in the valve, a natural circulation can be realized even with a small pressure difference inside and outside the air exchange cavity, improving the air exchange effect. When there is a peculiar smell in the air exchange cavity, the dissipation of the peculiar smell can be effectively accelerated.

[0037] Taking the first Tesla valve as an example below, the effect of the exhaust structure on gas flow will be described. The effect of the intake structure on gas flow is the same as that of the exhaust structure. Refer to Figure 1 and Figure 2 , Figure 1 shows the sectional structure of the exhaust structure, Figure 2 shows the sectional structure of a use state of the exhaust structure. As Figure 1 and Figure 2 ​As shown in the figure, multiple Tesla units 11 connected in series are provided inside the first Tesla valve 1. The Tesla unit 11 includes a main flow path 111 and a branch flow path 112. The main flow path 111 is inclined, and the branch flow path 112 is bent to form a semi-ring with both ends communicating with the main flow path 111. The orientations of the two ends of the branch flow path 112 communicating with the main flow path 111 are the same. The branch flow paths 112 of two adjacent Tesla units 11 connected in series are arranged on both sides of the main flow path 111, which is beneficial to arranging more branch flow paths 112 in a limited space and improving the acceleration and flow resistance effects of the first Tesla valve 1 on fluids including gases. It should be noted that the direction in which the first Tesla valve 1 produces an acceleration effect on the fluid is the forward direction of the first Tesla valve 1, and the direction in which the first Tesla valve 1 produces a flow resistance effect on the fluid is the reverse direction of the first Tesla valve 1. As Figure 1 shown in the figure, when the fluid flows into the Tesla unit 11 along the forward direction of the first Tesla valve 1, the fluid is divided into two parts. One part flows in the main flow path 111, and the other part enters the branch flow path 112. When the fluid in the branch flow path 112 returns to the main flow path 111, it flows in the same direction as the fluid in the main flow path 111, which accelerates the fluid in the main flow path 111. The fluid in the main flow path 111 continues to flow into the next Tesla unit 11 connected in series for further acceleration, thereby achieving the acceleration effect on the fluid inside the first Tesla valve 1. The more the number of Tesla units 11, the greater the acceleration effect on the fluid. As Figure 2 shown in the figure, when the fluid flows into the Tesla unit 11 along the reverse direction of the first Tesla valve 1, the fluid is divided into two parts. One part flows in the main flow path 111, and the other part enters the branch flow path 112. When the fluid in the branch flow path 112 returns to the main flow path 111, it flows in the opposite direction to the fluid in the main flow path 111, which hinders the fluid in the main flow path 111 and reduces the fluid flow rate. The fluid in the main flow path 111 continues to flow into the next Tesla unit 11 connected in series for further deceleration and obstruction. The more the number of Tesla units 11, the greater the resistance to fluid flow. Eventually, only a very small amount of fluid flows out or almost no fluid flows out, finally achieving the one-way conduction effect of the first Tesla valve 1. The forward direction of the first Tesla valve is the direction in which the gas flows from the inside of the air exchange cavity to the outside, and the forward direction of the second Tesla valve is the direction in which the gas flows from the outside of the air exchange cavity to the inside.

[0038] It should be noted that the exhaust structure can be provided with one first Tesla valve 1, or multiple first Tesla valves 1 can be arranged in parallel. Similarly, the intake structure can be provided with one second Tesla valve, or multiple second Tesla valves can be arranged in parallel. Those skilled in the art can adjust according to the usage situation to achieve the required one-way air circulation effect.

[0039] Optionally, the exhaust structure can be a tubular structure such as an exhaust pipe, the first Tesla valve is provided inside the pipe wall of the exhaust pipe, the intake structure can be a tubular structure such as an intake pipe, the second Tesla valve is provided inside the pipe wall of the intake pipe, the Tesla valve can be provided in any section of the tubular structure or can penetrate the entire section of the pipeline. Those skilled in the art can adjust according to needs, improving the versatility, and the tubular structure is convenient for layout; the exhaust structure can also include an exhaust pipe and a first valve housing, the first Tesla valve is provided inside the first valve housing, the intake structure can also include an intake pipe and a second valve housing, and the second Tesla valve is provided inside the second valve housing.

[0040] Optionally, a filter screen is provided at the intake end of the exhaust structure, and a filter screen is provided at the intake end of the intake structure, which is used to prevent impurities such as dust from entering the first Tesla valve and / or the second Tesla valve from the intake end, causing blockage of the first Tesla valve and / or the second Tesla valve, resulting in the failure of the fresh air component to function properly. The filter screen can adopt a single or a combination structure of a primary filter screen, a medium-efficiency filter screen, and a high-efficiency filter screen. Those skilled in the art can adjust according to needs.

[0041] The fresh air component further includes a fan and a heating device. The fan and the heating device are provided in the air exchange cavity. There can be one or more fans. When there is one fan, it can be connected to the exhaust structure or the intake structure. When there are multiple fans, at least one can be connected to the exhaust structure and at least one can be connected to the intake structure. When the automatic air exchange through only the intake structure and the exhaust structure cannot meet the usage requirements, the fan can be started to assist air flow and further improve the air exchange efficiency; the heating device can be a heat pump heating device, an electric heating tube heating device, or other heating devices. When the heating device is started, the air in the air exchange cavity is heated, increasing the air pressure in the air exchange cavity, increasing the pressure difference inside and outside the air exchange cavity, accelerating air circulation, and at the same time drying the moisture residue in the air exchange cavity and killing bacteria, further accelerating the odor dissipation speed and improving the odor dissipation effect. It should be noted that the fan and the heating device can be set simultaneously and used in cooperation, or only the fan can be set, or only the heating device can be set; in addition, the fan can also be provided outside the air exchange cavity, on the outlet side of the exhaust structure and / or on the inlet side of the intake structure, and the fan can also be provided inside the exhaust structure and / or inside the intake structure, as long as it can accelerate the air flow inside and outside the air exchange cavity. Those skilled in the art can adjust according to needs, all of which do not deviate from the principle of the present invention and fall within the protection scope of the present invention.

[0042] The present invention also provides a laundry treatment device, which can be a washing machine, a dryer, a washing and drying integrated machine, etc., and no specific limitation is made here.

[0043] As Figure 3 shown, Figure 3The overall structure of the laundry processing device is shown. Figure 3 As shown, when the clothing processing device is a device with a clothing washing function such as a washing machine and a washer-dryer, the clothing processing device includes a fresh air component, a processing cylinder 2, an outer cylinder 3, an outer shell 4, a water inlet tank 5, and a water inlet pipe 6. The processing cylinder 2 is an air exchange cavity, and an air exchange cavity is formed in the processing cylinder 2. The processing cylinder 2 is provided with a through hole; the outer cylinder 3 is sleeved outside the processing cylinder 2, and the outer cylinder 3 is connected to the air exchange cavity through the through hole, and the cylinder wall of the outer cylinder 3 is provided with air holes; the water inlet tank 5 is provided with a water inlet and a water outlet, and water is discharged from the water inlet. The water inlet 5 enters the water inlet groove 5, and no sealing structure is provided at the water inlet groove 5, so the water inlet groove 5 is connected with the air; the water inlet pipe 6 is an air intake structure, and a second Tesla valve is provided in the water inlet pipe 6. One end of the water inlet pipe 6 is connected with the water outlet, and the other end passes through the outer cylinder 3 and is provided in the air exchange cavity or at the tube mouth of the inner cylinder to achieve communication with the air exchange cavity; the exhaust structure is an exhaust pipe 7, and a first Tesla valve is provided in the exhaust pipe 7. One end of the exhaust pipe 7 is connected with the air vent to achieve communication with the air exchange cavity, and the other end is connected with the outside of the shell 4. The fan and the heating device can be provided between the outer cylinder 3 and the treatment cylinder 2 to assist air flow and improve air exchange efficiency. At the same time, it can also dry the treatment cylinder 2 and / or the residual water in the treatment cylinder 2 and kill bacteria, further improving the odor dissipation effect.

[0044] When the clothing processing device is in standby mode, since the processing drum 2 and the outer drum 3 are connected through the through hole on the processing drum 2, the exhaust pipe 7 is respectively connected to the air vent of the outer drum 3 and the outside of the outer shell 4, and a first Tesla valve is provided in the exhaust pipe 7, so that the gas in the processing drum 2 flows unidirectionally to the outside of the outer shell 4 through the exhaust pipe 7; since the water inlet pipe 6 is respectively connected to the water outlet and the air exchange chamber of the water inlet tank 6, a second Tesla valve is provided in the water inlet pipe 6, so that the gas outside the outer shell 4 flows unidirectionally to the inside of the processing drum 2 through the water inlet pipe 6; since the first Tesla valve and the second Tesla valve have an accelerating effect on the gas flowing forward in the valve, natural circulation can be achieved even if there is only a small pressure difference between the inside of the processing drum 2 and the outside of the outer shell 4, thereby improving the air exchange effect, effectively accelerating the dissipation of the odor in the processing drum 2, and improving the user experience.

[0045] When the clothes processing device is in the state of washing clothes, the water or the mixed liquid of detergent, treatment agent, etc. and water in the water inlet tank 5 is introduced into the treatment drum 2 through the water inlet pipe 6 for normal washing. Due to the setting of the second Tesla valve in the water inlet pipe 6, the flow rate of the water or the mixed liquid in the water inlet pipe 6 is increased, which improves the water inlet speed and avoids backflow. The water inlet pipe 6 is used for air intake when the clothes processing device is in the standby state, and is used for water intake when the clothes processing device is in the state of washing clothes, so that the water inlet pipe 6 is fully utilized and the increase in cost is reduced.

[0046] It should be noted that when the laundry treatment device washes, dries or otherwise treats clothes, heating is often required, which causes the temperature of the gas inside the treatment cylinder 2 and the outer cylinder 3 to rise, the pressure to increase, and a pressure difference to be generated with the gas outside the housing 4. By utilizing this pressure difference, the natural circulation of the gas inside the treatment cylinder 2 and outside the housing 4 can be achieved through the fresh air assembly, accelerating the dissipation of odors. When the natural circulation effect cannot meet the usage requirements, the fan and / or heating device can be started to assist the circulation. Possibly, to determine whether the natural circulation effect meets the usage requirements, a gas flow meter can be set in the exhaust pipe 7 and / or the water inlet pipe 6 to obtain the gas flow value. When the gas flow value is less than the set value, it is determined that the natural circulation effect cannot meet the usage requirements, and the fan and / or heating device is controlled to start.

[0047] Those skilled in the art can understand that although the water inlet pipe 6 is described as an air intake structure above, this is not restrictive. The air intake structure can also be a separately provided air intake pipe, and one end of the air intake pipe is communicated with the outside of the housing 4.

[0048] When the laundry treatment device is a dryer or other device that does not have the function of washing clothes, the laundry treatment device includes a fresh air assembly, a treatment cylinder, and a housing. The treatment cylinder is a ventilation cavity, a ventilation cavity is formed inside the treatment cylinder, and an air inlet and an air outlet are provided on the treatment cylinder; the exhaust structure is an exhaust pipe, one end of the exhaust pipe is communicated with the ventilation cavity through the air outlet, and the other end passes through the housing and is communicated with the outside of the housing; the air intake structure is an air intake pipe, one end of the air intake pipe is communicated with the ventilation cavity through the air inlet, and the other end passes through the housing and is communicated with the outside of the housing.

[0049] When the laundry treatment device is in the standby state, the gas inside the treatment cylinder flows unidirectionally to the outside of the housing through the exhaust pipe, and the gas outside the housing flows unidirectionally into the treatment cylinder through the air intake pipe. Since the first Tesla valve and the second Tesla valve have an accelerating effect on the gas flowing in the forward direction inside the valve, natural circulation can be achieved even with a small pressure difference between the inside of the treatment cylinder and the outside of the housing, improving the ventilation effect, effectively accelerating the dissipation of odors inside the treatment cylinder, and improving the user experience.

[0050] It should be noted that the above embodiments are only used to illustrate the principle of the present invention and are not intended to limit the protection scope of the present invention. Without departing from the principle of the present invention, those skilled in the art can adjust the above embodiments so that the present invention can be applied to more specific application scenarios.

[0051] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easily understood by those skilled in the art 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 all fall within the protection scope of the present invention.
