Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and more particularly to a dishwasher. Background Technology

[0002] As living standards improve, more and more families are equipped with dishwashers.

[0003] In related technologies, to improve the drying effect of dishwashers, the heat drift temperature can be increased or the time for the fan to blow hot air can be increased during the drying stage.

[0004] However, increasing the heat drift temperature or extending the time the fan blows hot air will result in a high inner tank temperature. Water vapor will be discharged from the exhaust port of the breather. The hot water vapor will be pre-cooled in the environment and will easily condense on the side columns and cabinet edges, affecting the user experience. Utility Model Content

[0005] This application provides a dishwasher that is less prone to condensation and offers a better user experience.

[0006] In a first aspect, embodiments of this application provide a dishwasher, comprising:

[0007] The inner liner has a cleaning chamber and a first outlet, which is connected to the cleaning chamber.

[0008] The respirator has an inner cavity, a first inlet that communicates with the inner cavity, and a first outlet that communicates with the first outlet; the respirator also has an air outlet that communicates with the inner cavity.

[0009] A waterproof and breathable membrane assembly is installed inside the inner cavity. Water vapor in the cleaning cavity flows sequentially through the first outlet, the first inlet, the waterproof and breathable membrane assembly, and the air outlet to the outside of the inner liner. The waterproof and breathable membrane assembly is configured to block the flow of water.

[0010] The dishwasher provided in this embodiment includes an inner tub, a breather, and a waterproof and breathable membrane assembly. Water vapor inside the cleaning chamber flows through a first outlet, a first inlet, the waterproof and breathable membrane assembly, and an air outlet to the outside of the inner tub and the outside of the breather. The waterproof and breathable membrane assembly effectively prevents moisture from escaping and causing condensation, thus avoiding negative impacts on the user experience.

[0011] In some embodiments, the respirator includes:

[0012] The respirator body has a first inlet and a first inner cavity, with the first inlet communicating with the first inner cavity; the respirator body also has a third outlet, which communicates with the first inner cavity.

[0013] The fixed cover is connected to the respirator body. The fixed cover has a second inner cavity and an air outlet located on the side of the fixed cover facing the inner liner. The air outlet communicates with the second inner cavity. The fixed cover also has a third inlet, which communicates with the second inner cavity and with the third outlet.

[0014] The lumen includes a first lumen and a second lumen.

[0015] In this way, the fixed cover guides the flow of water vapor, directing it towards the side facing the inner liner, thus keeping it further away from the outer shell or cabinet and reducing the formation of condensation.

[0016] In some embodiments, a waterproof and breathable membrane assembly is located between the respirator body and the fixed cover.

[0017] This facilitates the installation of the waterproof and breathable membrane assembly. During installation, the waterproof and breathable membrane assembly can be connected to the fixing cover and then installed as a whole on the respirator body. The respirator body and the fixing cover can protect the waterproof and breathable membrane assembly, thereby effectively preventing user misoperation from damaging the waterproof and breathable membrane assembly.

[0018] In some embodiments, a first fixing part is provided on the top of the respirator body, a second fixing part is provided on the fixing cover, and a waterproof and breathable membrane assembly is located between the first fixing part and the second fixing part. The first fixing part and the second fixing part are configured to press the waterproof and breathable membrane assembly together.

[0019] In this way, by using the first fixing part and the second fixing part to press the waterproof and breathable membrane assembly together, the waterproof and breathable membrane assembly can achieve a sealing effect, which helps to reduce the leakage of filtered water from the gap between the fixed shell and the respirator body to the outside of the respirator.

[0020] In some embodiments, the air outlet is located at the upper part of the fixed cover, but not at the top of the fixed cover, and the inner wall of the air outlet has a gap with the top of the fixed cover.

[0021] The second inner cavity includes a first region and a second region. The lower part of the first region is connected to the first inner cavity, and the upper part of the first region is connected to the side of the second region away from the air outlet. The air outlet is connected to the second region.

[0022] In this way, by setting up a first area and a second area, and ensuring that the first area and the second area are not on the same straight line, it is possible to effectively prevent debris from entering the second area through the air outlet and then damaging the waterproof and breathable membrane component through the first area.

[0023] In some embodiments, the respirator includes:

[0024] The respirator body has a first inlet, an inner cavity, and an air outlet.

[0025] The waterproof and breathable membrane assembly is located near the air outlet.

[0026] In this way, the water vapor has a longer flow path, which facilitates the cooling of the water vapor and can block more water.

[0027] In some embodiments, the respirator further includes;

[0028] A water-guiding structure is located in the first inner cavity, below the waterproof and breathable membrane assembly.

[0029] The water storage structure is located below the water diversion structure.

[0030] The water intake structure is configured to receive water filtered by the waterproof and breathable membrane assembly and guide the water flow to the water storage structure. When the water storage structure is connected to the inner tank, the water storage structure is configured to discharge water into the inner tank.

[0031] In this way, during the dishwasher's washing cycle, water from the water storage structure can enter the dishwasher to wash the dishes, which helps to save energy.

[0032] In some embodiments, the water intake structure includes at least two partition ribs, with the height of the top of the partition ribs decreasing from the side away from the water storage structure to the side closer to the water storage structure.

[0033] At least two dividing ribs are spaced apart along the height direction, and the orthographic projections of two adjacent dividing ribs toward the horizontal plane overlap.

[0034] In this way, by setting up the dividing ribs, water vapor can move to the top of the respirator through the gap between two adjacent ribs, which is beneficial to the flow of water vapor. Furthermore, the orthographic projections of two adjacent ribs onto the horizontal plane overlap, making it less likely for water to drip from the gap between them.

[0035] In some embodiments, the waterproof and breathable membrane assembly includes an adhesive layer, a waterproof and breathable membrane layer, and a sealing layer stacked sequentially, with the sealing layer located on the air inlet side of the waterproof and breathable membrane layer.

[0036] In this way, the adhesive layer is used to bond and fix the waterproof and breathable membrane components, resulting in high installation efficiency. The sealing layer is used for compression deformation to improve the sealing performance.

[0037] Secondly, embodiments of this application provide a dishwasher, comprising:

[0038] The inner liner has a cleaning chamber.

[0039] The respirator has an inner cavity that communicates with the cleaning chamber. Water vapor in the cleaning chamber flows through the inner cavity to the outside of the inner liner and then to the outside of the respirator.

[0040] A waterproof and breathable membrane assembly is located in the path of water vapor flow and is configured to block the flow of water.

[0041] The dishwasher provided in this embodiment includes an inner tub, a breather, and a waterproof and breathable membrane assembly. Water vapor inside the cleaning chamber flows through the breather to the outside of the inner tub and then to the outside of the breather. The waterproof and breathable membrane assembly is located in the path of the water vapor flow. By blocking moisture through the waterproof and breathable membrane assembly, it effectively prevents high-temperature water vapor from escaping and causing condensation, thus avoiding impacting the user experience.

[0056] As described in the background section, drying and condensation are two important factors affecting the user experience of dishwashers. Drying and condensation in dishwashers are interconnected. To improve drying efficiency, the heat drift temperature can be increased, or the duration of hot air blowing by the fan during the drying stage can be extended. However, increasing the heat drift temperature or extending the hot air blowing time leads to a high inner tank temperature. Water vapor is then expelled from the vent of the breather. This hot water vapor is pre-cooled in the environment, easily causing condensation on the side pillars and cabinet edges, thus affecting the user experience.

[0057] To address the aforementioned technical problems, this application provides a dishwasher comprising an inner tub, a breather, and a waterproof and breathable membrane assembly. Water vapor within the cleaning chamber flows through the breather to the outside of the inner tub and then to the outside of the breather. The waterproof and breathable membrane assembly is located along the water vapor flow path. By blocking moisture through the waterproof and breathable membrane assembly, it effectively prevents high-temperature water vapor from escaping and causing condensation, thus avoiding negative impacts on the user experience.

[0069] Specifically, the door is equipped with a handle.

[0070] In some embodiments, the dishwasher includes a control panel for user input of control commands.

[0071] The control panel is located on the cabinet. Specifically, it is situated above the door.

[0072] In some embodiments, the housing includes a base. The base is used to support components such as the inner liner.

[0073] In some embodiments, the enclosure includes an outer shell. The outer shell serves both a protective and aesthetic purpose.

[0077] Specifically, the inner liner is equipped with a cleaning chamber.

[0078] The inner liner is provided with a cleaning chamber and a first outlet, which is connected to the cleaning chamber.

[0079] Specifically, the first outlet is located on the side wall at one end of the inner liner along its width.

[0080] In some embodiments, the dishwasher includes a drainage device.

[0081] The drainage device is located inside the base and is connected to the inner tank. The drainage device is used to connect to the drain pipe so that the cleaned water in the inner tank can be discharged into the sewer.

[0090] Figure 1 This is a schematic diagram of a respirator and waterproof breathable membrane assembly in a dishwasher provided in an embodiment of this application. Figure 2 for Figure 1 sectional view, Figure 3 for Figure 2 A magnified view of a portion of point A in the middle.

[0091] See Figures 1 to 3 As shown, in some embodiments, the dishwasher includes a breather 100. The breather 100, also known as a ventilation device or air gap, plays an important role in effectively preventing dirty water from the dishwasher from flowing back into the household water supply system.

[0092] In some embodiments, the respirator 100 is located on one side of the inner liner along its width. Alternatively, the respirator 100 is located on the rear side of the inner liner.

[0093] The respirator 100 has an inner cavity. The respirator 100 has a first inlet 110, which communicates with the inner cavity and a first outlet. The respirator 100 also has an air outlet 120, which communicates with the inner cavity.

[0094] In some embodiments, the dishwasher includes a waterproof and breathable membrane assembly 200. The waterproof and breathable membrane assembly 200 can act as a barrier, blocking moisture in hot water vapor while allowing gas to pass through.

[0095] When the dishwasher is washing or drying, water vapor generated inside the cleaning chamber of the inner tank enters the outside of the inner tank through the breather 100 and enters the air. The waterproof and breathable membrane assembly 200 is located in the path of water vapor flow.

[0096] It is understood that the dishwasher provided in this embodiment includes an inner tub, a breather 100, and a waterproof and breathable membrane assembly 200. Water vapor inside the cleaning chamber flows through the breather 100 to the outside of the inner tub and then to the outside of the breather 100. The waterproof and breathable membrane assembly 200 is located in the path of the water vapor flow. By blocking moisture through the waterproof and breathable membrane assembly 200, it effectively prevents high-temperature water vapor from escaping and causing condensation, thus avoiding impacting the user experience.

[0097] In some embodiments, the dishwasher includes a fan. The fan is configured to accelerate the flow of air within the cleaning chamber.

[0098] In some embodiments, the dishwasher includes a heater. The heater is configured to heat the air within the cleaning chamber.

[0099] In some embodiments, the dishwasher includes a controller. Both the fan and the heater are electrically connected to the controller. During the drying phase of the dishwasher, the controller is configured to keep the fan and heater running.

[0100] It should be noted that during the heat dissipation and drying stages, for example, the fan and heater can be continuously operated during the drying stage (typically, during the drying stage, to prevent condensation from forming during dishwasher operation, the fan and heater operate intermittently, for example, operating for 1.5 minutes and stopping for 2 minutes, to effectively prevent the fan from running for too long and carrying out more hot steam), continuously circulating hot air into the inner tank, improving the drying effect of the inner tank and tableware. Furthermore, due to the blocking effect of the waterproof and breathable membrane component 200, high-temperature water vapor is less likely to enter the air through the breather 100, thus preventing condensation. Moreover, while improving the drying effect, drying time can be reduced, enhancing the user experience.

[0101] In some embodiments, the waterproof and breathable membrane assembly 200 is disposed in the inner liner and covers the first outlet. That is, the waterproof and breathable membrane assembly 200 is disposed on the inner wall of the inner liner.

[0102] In some embodiments, the waterproof and breathable membrane assembly 200 is located between the inner liner and the respirator 100, and the waterproof and breathable membrane assembly 200 covers the first outlet. That is, the waterproof and breathable membrane assembly 200 is disposed on the outer wall of the inner liner.

[0103] In some embodiments, the waterproof and breathable membrane assembly 200 is located between the inner liner and the respirator 100, and the waterproof and breathable membrane assembly 200 covers the first inlet 110. That is, the waterproof and breathable membrane assembly 200 is disposed on the outer wall of the respirator 100.

[0104] In some embodiments, the waterproof and breathable membrane assembly 200 is disposed within the respirator 100. This allows the filtered water from the waterproof and breathable membrane assembly 200 to remain within the respirator 100, minimizing its impact on the drying effect within the cleaning chamber and preventing overflow into the area between the inner liner and the outer shell, thus avoiding damage to other components. Furthermore, the user has limited access to the waterproof and breathable membrane assembly 200, reducing the risk of accidental damage.

[0105] The water vapor in the cleaning chamber flows to the outside through the first outlet, the first inlet 110, the waterproof and breathable membrane assembly 200, and the air outlet 120.

[0106] The dishwasher provided in this embodiment includes an inner tank, a breather 100, and a waterproof and breathable membrane assembly 200. Water vapor inside the cleaning chamber flows to the outside through a first outlet, a first inlet 110, the waterproof and breathable membrane assembly 200, and an air outlet 120. The waterproof and breathable membrane assembly 200 effectively blocks moisture, preventing high-temperature water vapor from escaping and causing condensation, thus avoiding negative impacts on the user experience.

[0107] Figure 4 This is a schematic diagram of the structure of the respirator body in the dishwasher provided in an embodiment of this application. Figure 5 for Figure 4 A magnified view of a section at point B in the middle.

[0108] See Figure 4 and Figure 5 As shown, in some embodiments, the respirator 100 includes a respirator body 130.

[0109] The respirator body 130 is provided with a first inlet 110. The respirator body 130 includes a first inner cavity 135, and the first inlet 110 communicates with the first inner cavity 135. The respirator body 130 is provided with a third outlet 131, and the third outlet 131 communicates with the first inner cavity 135.

[0110] Figure 6 This is a schematic diagram of the structure of the fixed cover in the dishwasher provided in an embodiment of this application. Figure 7 for Figure 6 A structural diagram from another angle.

[0111] See Figure 6 and Figure 7 As shown, in some embodiments, the respirator 100 includes a fixed cover 140. The fixed cover 140 is used to guide the flow of water vapor, directing the water vapor towards the side facing the inner liner, thereby reducing the distance from the outer shell or cabinet and minimizing the formation of condensate.

[0112] The fixed cover 140 is connected to the respirator body 130. The fixed cover 140 is provided with a second inner cavity 145 and an air outlet 120, which communicates with the second inner cavity 145. The air outlet 120 is located on the side of the fixed cover 140 facing the inner liner.

[0113] The fixed cover 140 is provided with a third inlet 141, which communicates with the second inner cavity 145 and the third outlet 131. The inner cavity includes a first inner cavity 135 and a second inner cavity 145.

[0114] In some embodiments, a retaining cover 140 is disposed on top of the respirator body 130.

[0115] In some embodiments, a first positioning structure 132 is provided on the top of the respirator body 130, and a second positioning structure 142 matching the first positioning structure 132 is provided on the fixed cover 140. The first positioning structure 132 and the second positioning structure 142 are connected to ensure that the respirator body 130 and the fixed cover 140 are accurately positioned.

[0116] Specifically, one of the first positioning structure 132 and the second positioning structure 142 includes a positioning hole, and the other includes a positioning post. The positioning post is inserted into the positioning hole.

[0117] In some embodiments, the number of first positioning structures 132 is at least two. The number of second positioning structures 142 is at least two. The at least two first positioning structures 132 are arranged at intervals. The at least two first positioning structures 132 and the at least two second positioning structures 142 are arranged in a one-to-one correspondence.

[0118] In some embodiments, a first connecting structure 133 is provided on the top of the respirator body 130, and a second connecting structure 143 matching the first connecting structure 133 is provided on the fixed cover 140. A connector is inserted into the first connecting structure 133 via the second connecting structure 143 so that the first connecting structure 133 and the second connecting structure 143 are connected, and the respirator body 130 and the fixed cover 140 are connected.

[0119] Specifically, the connector can be a screw. The second connecting structure 143 can include a threaded hole or a smooth hole. The first connecting structure 133 includes a threaded hole.

[0120] In some embodiments, the number of first connection structures 133 is at least two. The number of second connection structures 143 is at least two. The at least two first connection structures 133 are arranged at intervals. The at least two first connection structures 133 and the at least two second connection structures 143 are arranged in a one-to-one correspondence.

[0121] See Figure 3 As shown, in some embodiments, the waterproof and breathable membrane assembly 200 is located between the respirator body 130 and the fixing cover 140. This facilitates the installation of the waterproof and breathable membrane assembly 200. During installation, the waterproof and breathable membrane assembly 200 can be connected to the fixing cover 140 and then installed as a whole on the respirator body 130. The respirator body 130 and the fixing cover 140 can protect the waterproof and breathable membrane assembly 200, thereby effectively preventing user misoperation from damaging the waterproof and breathable membrane assembly 200.

[0122] Specifically, water vapor in the cleaning chamber flows through the first outlet, the first inlet 110, the first inner cavity 135, the third outlet 131, the waterproof and breathable membrane assembly 200, the third inlet 141, the second inner cavity 145, and the air outlet 120 to the outside of the respirator 100.

[0123] See Figures 4 to 6 As shown, in some embodiments, a first fixing part 134 is provided on the top of the respirator body 130, and a second fixing part 144 is provided on the fixing cover 140. When the fixing cover 140 is connected to the respirator body 130, the first fixing part 134 and the second fixing part 144 face each other, and the waterproof and breathable membrane assembly 200 is located between the first fixing part 134 and the second fixing part 144. The first fixing part 134 and the second fixing part 144 are configured to press the waterproof and breathable membrane assembly 200 together. In this way, by pressing the waterproof and breathable membrane assembly 200 together with the first fixing part 134 and the second fixing part 144, the waterproof and breathable membrane assembly 200 can achieve a sealing effect, which helps to reduce the leakage of filtered water from the gap between the fixing shell and the respirator body 130 to the outside of the respirator 100.

[0124] The first fixing part 134 can be a fixing rib or a fixing protrusion, and the second fixing part 144 can be a fixing rib or a fixing protrusion.

[0125] Specifically, after the waterproof and breathable membrane assembly 200 is bonded to the second fixing part 144, the fixing cover 140 is connected to the respirator body 130. After connection, the distance between the first fixing part 134 and the second fixing part 144 is less than the thickness of the waterproof and breathable membrane assembly 200 in the unstressed state. Therefore, the first fixing part 134 and the second fixing part 144 can press the waterproof and breathable membrane assembly 200 together, thereby improving the sealing effect.

[0126] In some embodiments, the shapes of the first fixing part 134, the second fixing part 144, and the waterproof and breathable membrane assembly 200 are matched.

[0127] In some embodiments, the vent 120 is located on the upper part of the fixed cover 140, and the inner wall of the vent 120 is spaced apart from the top of the fixed cover 140. The vent 120 is not located on the top of the fixed cover 140. The vent 120 is located on the side of the fixed cover 140.

[0128] The second inner cavity 145 includes a first region 1451 and a second region 1452. The lower part of the first region 1451 is connected to the first inner cavity 135, and the upper part of the first region 1451 is connected to the side of the second region 1452 away from the air outlet 120. The air outlet 120 is connected to the second region 1452.

[0129] It is understandable that by setting a first area 1451 and a second area 1452, and the first area 1451 and the second area 1452 are not located on the same straight line, it is effectively prevented that debris enters the second area 1452 through the air outlet 120 and then damages the waterproof and breathable membrane assembly 200 through the first area 1451.

[0130] From the side closer to the air outlet 120 to the side farther away from the air outlet 120, the height of the inner top surface of the second region 1452 increases, and the height of the inner bottom surface of the second region 1452 increases.

[0131] Understandably, the second region 1452 extends upward, thereby effectively preventing debris from entering the second region 1452 through the air outlet 120 and then damaging the waterproof and breathable membrane assembly 200 through the first region 1451.

[0132] Figure 8 This is a schematic diagram of the structure of the first cover plate, the waterproof and breathable membrane assembly, and the fourth fixing part in the dishwasher provided in the embodiments of this application. Figure 9 for Figure 8 A magnified view of a section at point C.

[0133] See Figure 8 and Figure 9 As shown, in some embodiments, the respirator 100 includes a respirator body 130.

[0134] The respirator body 130 is provided with a first inlet 110 and includes an inner cavity, with the first inlet 110 communicating with the inner cavity 135. The respirator body 130 is provided with an air outlet 120, which is also communicating with the inner cavity 135.

[0135] The waterproof and breathable membrane component 200 is located in the inner cavity 135 and close to the air outlet 120. This allows for a longer flow path for water vapor, facilitating its cooling and thus blocking more water.

[0136] Water vapor in the cleaning chamber flows through the first outlet, the first inlet 110, the inner cavity, the waterproof and breathable membrane assembly 200, and the air outlet 120 to the outside of the respirator body 130.

[0137] It is understandable that the fixed cover 140 has been eliminated in this embodiment, thereby reducing the number of parts and lowering costs.

[0138] In some embodiments, the respirator body 130 includes a first cover plate 136 and a second cover plate 137 connected to each other, the first cover plate 136 and the second cover plate 137 together forming an air outlet 120. The air outlet 120 is located at the top of the respirator body 130.

[0139] The inner wall of the first cover plate 136 is provided with a third fixing part 138, and the inner wall of the second cover plate 137 is provided with a fourth fixing part 139.

[0140] The third fixing part 138 can be a fixing rib or a fixing protrusion, and the fourth fixing part 139 can be a fixing rib or a fixing protrusion.

[0141] It should be noted that the first cover plate 136 and the second cover plate 137 can be connected by hot plate welding.

[0142] In some embodiments, the inner wall of the first cover plate 136 is provided with a third positioning structure, and the inner wall of the second cover plate 137 is provided with a fourth positioning structure.

[0143] Specifically, one of the third and fourth positioning structures includes a positioning hole, and the other includes a positioning post. The positioning post is inserted into the positioning hole.

[0144] In some embodiments, the number of third positioning structures is at least two. The number of fourth positioning structures is at least two. The at least two third positioning structures are spaced apart. The at least two third positioning structures are arranged in a one-to-one correspondence with the at least two fourth positioning structures.

[0145] Figure 10 This is a partial structural diagram of the breather in a dishwasher provided in an embodiment of this application.

[0146] See Figure 10 As shown, in some embodiments, the respirator 100 also includes a water-guiding structure. The water-guiding structure is used to receive water blocked by the waterproof and breathable membrane assembly 200 and to guide the flow of water.

[0147] The water-guiding structure is located in the first inner cavity 135, and is located below the waterproof and breathable membrane assembly 200.

[0148] In some embodiments, the respirator 100 further includes a water storage structure 150. The water storage structure 150 is used to store water.

[0149] The water storage structure 150 is located below the water diversion structure 160.

[0150] The water intake structure 160 is configured to receive water filtered by the waterproof and breathable membrane assembly 200 and guide the water flow to the water storage structure 150. When the water storage structure 150 is connected to the inner tank, it is configured to discharge water into the inner tank. In this way, during the dishwasher washing cycle, the water in the water storage structure 150 can enter the dishwasher to wash the dishes, which helps to save energy.

[0151] In some embodiments, the respirator 100 further includes a control valve. The control valve is configured to control the connection or disconnection between the water storage structure 150 and the inner tank.

[0152] Specifically, the control valve can be an electric valve.

[0153] In some embodiments, the water intake structure 160 includes at least two partition ribs 161, with the height of the top of the partition ribs 161 decreasing from the side away from the water storage structure 150 to the side closer to the water storage structure 150.

[0154] At least two partition ribs 161 are spaced apart along the height direction, and the orthographic projections of two adjacent partition ribs 161 toward the horizontal plane overlap.

[0155] Understandably, by setting the dividing ribs 161, water vapor can move to the top of the respirator 100 through the gap between two adjacent dividing ribs 161, which is beneficial to the flow of water vapor. Moreover, the orthographic projections of two adjacent dividing ribs 161 toward the horizontal plane overlap, making it less likely for water to drip from the gap between the two adjacent dividing ribs 161.

[0156] Specifically, the number of separator ribs 161 can be multiple. For example, three or four, etc.

[0157] In some embodiments, the partition rib 161 contacts the first cover plate 136 and the second cover plate 137. That is, along the direction from the first cover plate 136 to the second cover plate 137, the size of the partition rib 161 and the spacing between the first cover plate 136 and the second cover plate 137 are equal.

[0158] Figure 11 This is a schematic diagram of the structure of the waterproof and breathable membrane assembly in the dishwasher provided in an embodiment of this application.

[0159] See Figure 11 As shown, in some embodiments, the waterproof and breathable membrane assembly 200 includes an adhesive layer, a waterproof and breathable membrane layer 210, and a sealing layer stacked sequentially. The sealing layer is located on the air inlet side of the waterproof and breathable membrane layer 210.

[0160] Water vapor flowing out from the inner liner enters the respirator 100, and then enters the waterproof and breathable membrane layer 210 from the direction of the sealing layer.

[0161] The adhesive layer is used to bond and fix the waterproof and breathable membrane component 200, which has a high installation efficiency.

[0162] Specifically, the adhesive layer can be a foam adhesive layer.

[0163] In some embodiments, the adhesive layer is in the form of a ring. Alternatively, the adhesive layer is in the form of a rectangular ring.

[0164] The waterproof and breathable membrane layer 210 is used to block liquids through gas.

[0165] In some embodiments, the adhesive layer is circular. Alternatively, the adhesive layer is rectangular.

[0166] The sealing layer 220 is used for extrusion deformation to improve sealing performance.

[0167] Specifically, the sealing layer 220 can be a foam layer, a sponge layer, or a rubber layer, etc.

[0168] In some embodiments, the sealing layer 220 is annular. Alternatively, the sealing layer 220 is a rectangular annular shape.
