DETAILED DESCRIPTION

[0043] In order to make the technical personnel in the technical field to which the present application belongs to understand the present application more clearly, the technical scheme in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0044] In the related art, for electrical appliances such as household dishwashers and commercial dishwashing cabinets with limited space, the size of the breather is very small. When water flows through the breather, the impeller rotation rate of the water level detection component of the breather is very likely to fluctuate when detecting the water level, resulting in unstable pulse number representing the number of impeller rotations and inaccurate water level detection.

[0045] The first aspect of the present application provides a respirator which can be applied to electrical equipment, such as household dishwashers, commercial dishwashing cabinets, etc. It can improve the stability of impeller rotation to a certain extent, stabilize the number of pulses, and ensure the accuracy of water intake detection.

[0046] See also Figure 1 as well as Figure 2 The respirator 100 provided in the embodiment of the present application includes a housing 110 and a water volume detection assembly 130. The housing 110 is provided with a water flow channel 160 and a receiving chamber 170. The water flow channel 160 includes a water inlet channel 161 and a water outlet channel 162. The water inlet channel 161, the receiving chamber 170 and the water outlet channel 162 are sequentially connected. Water flows from the water inlet channel 161 into the receiving chamber 170 and then is discharged through the water outlet channel 162. The water volume detection assembly 130 is arranged in the receiving chamber 170. When water flows through the receiving chamber 170, the water volume detection assembly 130 can detect the amount of water flowing through the receiving chamber, that is, detect the amount of water inflow.

[0047] See also Figure 3 , Figure 4 , Fig.11 , Fig.12 , Fig.14 as well as Fig.16At least part of the water flow channel 160 is provided with a flow stabilizing section 163, and at least one of the water inlet channel 161 and the water outlet channel 162 is provided with a flow stabilizing section 163, that is, the water inlet channel 161 and / or the water outlet channel 162 are provided with a flow stabilizing section 163, for example, the water inlet channel 161 is provided with a flow stabilizing section 163, or the water outlet channel 162 is provided with a flow stabilizing section 163, or both the water inlet channel 161 and the water outlet channel 162 are provided with a flow stabilizing section 163, so as to slow down the water inlet speed and / or water outlet speed of the accommodating cavity. In some embodiments, when the flow stabilizing section 163 is located in the water inlet channel 161, the water outlet speed of the flow stabilizing section 163 is lower than the water inlet speed of the accommodating cavity 170, so as to stabilize the water inlet speed of the accommodating cavity 170; when the flow stabilizing section 163 is located in the water outlet channel 162, the water outlet speed of the flow stabilizing section 163 is lower than the water outlet speed of the accommodating cavity 170, so as to stabilize the water outlet speed of the accommodating cavity 170; when both the water inlet channel 161 and the water outlet channel 162 are provided with the flow stabilizing section 163, the water outlet speed of the flow stabilizing section 163 of the water inlet channel 161 is lower than the water inlet speed of the accommodating cavity 170, and the water outlet speed of the flow stabilizing section 163 of the water outlet channel 162 is lower than the water outlet speed of the accommodating cavity 170, so as to stabilize the water inlet speed and the water outlet speed of the accommodating cavity 170.

[0048] Water flows into the accommodating cavity 170 from the water inlet channel 161 and then is discharged through the water outlet channel 162; the water volume detection component 130 is disposed in the accommodating cavity 170 and can detect the amount of water flowing through the accommodating cavity 170. Since the water outlet speed of the steady flow section 163 of the water flow channel 160 is lower than the water inlet speed or / and the water outlet speed of the accommodating cavity 170, the water inlet speed or / and the water outlet speed of the accommodating cavity 170 can be stabilized. The smaller the fluctuation of the water inlet speed or / and the water outlet speed, the smaller the fluctuation of the water inlet speed of the respirator 100 caused by the water volume detection component 130 itself, the more stable the number of pulses emitted by the water volume detection component 130, and the more accurate the water volume detection result, thereby improving the working stability of the dishwasher.

[0049] The housing 110 serves as the physical structure of each flow channel and chamber and the installation base of the water quantity detection assembly. In some embodiments, see Figure 1 as well as Figure 2 The shell 110 includes a first sheet 111, a second sheet 112, a side plate 115 and a plurality of partitions 113. The side plate 115 is connected to the edges of the first sheet 111 and the second sheet 112. The first sheet 111, the second sheet 112 and the side plate 115 together form an installation space. The plurality of partitions 113 are all located in the installation space, and each partition 113 is connected to the first sheet 111 and the second sheet 112. The first sheet 111, the second sheet 112, the side plate 115 and the partition 113 together form a water flow channel 160 and a accommodating cavity 170.

That is to say, along the direction perpendicular to the flow flow, the dimension of the flow stabilizing section 163 is smaller than the dimension of the water flow channel 160, and by narrowing the water flow channel 160 and then widening the water flow channel 160, the water outlet speed of the flow stabilizing section 163 is smaller than the water inlet speed and / or the water outlet speed of the accommodating cavity 170, thereby stabilizing the water inlet speed and / or the water outlet speed of the accommodating cavity 170.

For ease of explanation, the two opposite side walls of the flow stabilizing section 163 perpendicular to the direction of water flow, for example, the two opposite side walls of the flow stabilizing section 163 along the width direction are named as the first side wall and the second side wall. In some embodiments, the first water retaining member 121 is connected to the first side wall of the flow stabilizing section 163, and the first water retaining member 121 is spaced apart from the second side wall to form a water hole 121a. In other embodiments, the first water retaining member 121 is connected to the second side wall of the flow stabilizing section 163, and the first water retaining member 121 is spaced apart from the first side wall to form a water hole 121a. Of course, in other embodiments, the two opposite side walls of the flow stabilizing section 163 along the thickness direction can also be named as the first side wall and the second side wall.

[0067] In some embodiments, the two sides of the water outlet 166 in the thickness direction and the two sides of the water outlet end of the water outlet channel 162 in the thickness direction have a distance to form a step in the thickness direction of the water outlet channel 162 and the water outlet 166, and the buffer 125 is disposed at the step on at least one side of the water outlet end of the water outlet channel 162 in the thickness direction to stabilize the water outlet flow rate of the respirator 100. In other embodiments, the buffer 125 is disposed at the steps on both sides of the water outlet end of the water outlet channel 162 in the thickness direction.

[0068] In other embodiments, if both sides of the water outlet 166 in the thickness direction and the width direction are spaced from the sides of the water outlet end of the water outlet channel 162 to form a step between the water outlet channel 162 and the water outlet 166, the buffer 125 can be disposed at the step on at least one side of the water outlet end of the water outlet channel 162 to stabilize the water outlet flow rate of the respirator 100. In some embodiments, the buffer 125 is connected to at least one of the second sheet 111 and the partition 113.

[0069] In some embodiments, the buffer 125 is a ring member, and the buffer 125 covers the step formed by the water outlet channel 162 and the water outlet 166. The inner ring diameter of the buffer 125 decreases in the direction of water flow, and the inner ring surface of the buffer 125 forms a buffer surface. In other embodiments, the buffer 125 can be a buffer block, and the buffer block is provided with a buffer surface.

[0070] In some embodiments, the cross-sectional shape of the water outlet channel 162 is a rectangle, and the cross-sectional shape of the water outlet 166 is a circle. The wide side of the rectangle is equal to the diameter of the circle, the long side of the rectangle is larger than the diameter of the circle, and the projection of the circle along the direction of water flow falls into the rectangle. The water outlet channel 162 is formed with stepped surfaces in the thickness direction, that is, on both sides of the long side, and the buffer member 125 is located on one side of the thickness direction of the water outlet channel 162.

[0071] In some embodiments, when the flow stabilizing section 163 is arranged in the water outlet channel 162, the flow stabilizing section 163 is farther away from the water outlet 166 than the buffer member 125, that is, water first flows through the flow stabilizing structure with a contraction pattern and / or the flow stabilizing structure with a first water retaining member 121, and then acts on the buffer member 125. The water flows through the flow stabilizing section 163 and the buffer member 125 in turn, further stabilizing the water flow rate.

[0072] In some embodiments, see Figure 3 as well as Fig. 9 The shell 110 is also provided with a connected water storage cavity 180 and an air vent 182. The water outlet end of the water outlet channel 162 is provided with a connecting port 183 that is connected to the water storage cavity 180. The setting of the air vent 182 allows the water storage cavity 180 to be connected to the outside world. If the water in the water cup of the dishwasher has a siphon effect and flows back to the water storage cavity 180 of the respirator through the water outlet pipe 150, since the water storage cavity 180 is connected to the outside world through the air vent 182, the external air pressure forces the water in the water storage cavity 180 to flow back to the water cup through the water outlet pipe 150, so as to avoid the phenomenon that the water in the water cup of the dishwasher has a siphon effect and enters the respirator or even the municipal water network. The setting of the connecting port 183 allows the water in the water outlet channel 162 to be temporarily stored in the water storage cavity 180. Please refer to Figure 5 as well as Figure 6 A blocking member 126 is provided in the connecting port 183 to reduce the aperture of the connecting port 183 , thereby preventing excessive water from entering the water storage cavity 180 and causing water to spray from the air inlet channel 181 and the air vent 182 .

[0073] In some embodiments, see Figure 6, the blocking member 126 is disposed on at least one side of the communication port 183 to reduce the aperture of the communication port 183. In some embodiments, the blocking member 126 is disposed on one or both sides of the communication port 183 along the thickness direction, in some embodiments, the blocking member 126 is disposed on one or both sides of the communication port 183 along the width direction, in some embodiments, the blocking member 126 is connected to two side walls disposed oppositely in the thickness direction of the communication port 183, and the blocking member 126 and the two side walls in the width direction of the communication port 183 are spaced apart. In other embodiments, the blocking member 126 is connected to two side walls disposed oppositely in the width direction of the communication port 183, and the blocking member 126 and the two side walls in the thickness direction of the communication port 183 are spaced apart.

[0074] In some embodiments, the blocking member 126 is connected to the partition 113, the first sheet 111 or the second sheet 112. In another embodiment, the blocking member 126 is connected to two of the partition 113, the first sheet 111 and the second sheet 112. In some embodiments, the blocking member 126 can be a blocking block or a blocking plate, and the shape of the blocking member 126 can be a cube, a cuboid or a spherical shape.

[0075] In some embodiments, see Figure 3 The water storage cavity 180 is provided with an air inlet channel 181, and the air inlet channel 181 is connected with the air vent 182, so that air enters the water storage cavity 180 through the air vent 182 and the air inlet channel 181, and a second water blocking member 122 is provided in the air inlet channel 181 to prevent the water in the water storage cavity 180 from being discharged through the air inlet channel 181 and the air vent 182. Figure 1 , an air inlet 122a is provided on the second water retaining member 122, so that air can enter the water storage cavity 180, so as to avoid the phenomenon that the water in the water cup of the dishwasher is sucked into the respirator or even the municipal water network. In some embodiments, an air inlet 122a is provided in the middle of the second water retaining member 122. In some embodiments, a plurality of air inlet holes 122a are provided, and the plurality of air inlet holes 122a are arranged at intervals. In some embodiments, the axial direction of the air inlet hole 122a is parallel to the axial direction of the air inlet channel 181. In some embodiments, the axial direction of the air inlet hole 122a and the axial direction of the air inlet channel 181 have an angle.

[0076] In addition, when the dishwasher is running, the inner tank of the dishwasher will generate a large amount of steam, which will increase the internal air pressure of the inner tank. The steam may hit the door of the dishwasher, causing the door to make abnormal noises, affecting the user experience. By setting the air inlet 122a, part of the internal steam of the inner tank can be discharged through the air inlet 122a to balance the internal air pressure of the machine, reduce the abnormal noise of the door, and improve the user experience.

[0077] In some embodiments, one side of the second water retaining member 122 is connected to a side wall of the air inlet channel 181, and the other side of the second water retaining member 122 and the other side wall of the air inlet channel 181 are configured to form an air inlet hole 122a. In some embodiments, the second water retaining member 122 is connected to the side wall of the air inlet channel 181 along the width direction or the side wall of the air inlet channel 181 along the thickness direction.

The second water retaining member 122 is spaced apart from at least one of the baffle 113, the first sheet 111, and the second sheet 112 to form an air inlet hole.

[0078] In some embodiments, see Figure 2 , multiple second water retaining members 122 are arranged at intervals along the air inlet direction, for example, two, three or four, and multiple second water retaining members 122 are connected to the same side wall of the air inlet channel 181, for example, multiple second water retaining members 122 are all connected to one of the side walls in the width direction of the air inlet channel 181, or multiple second water retaining members 122 are all connected to one of the side walls in the thickness direction of the air inlet channel 181. In some embodiments, multiple second water retaining members 122 are staggeredly connected to two opposite side walls of the air inlet channel 181, for example, multiple second water retaining members 122 are staggeredly connected to two side walls in the thickness direction of the air inlet channel 181, or multiple second water retaining members 122 are staggeredly connected to two side walls in the width direction of the air inlet channel 181.

[0079] In some embodiments, the second water retaining member 122 can be at least one of a water retaining block and a water retaining protrusion. In some embodiments, the second water retaining member 122 can also be a water retaining plate. In some embodiments, the shape of the second water retaining member 122 can be circular, elliptical, or polygonal such as a quadrilateral or a pentagon.

[0080] In some embodiments, see Figure 3 , Figure 7 as well as Fig. 9The housing 110 further includes a third water retaining member 123 located in the water storage cavity 180. The third water retaining member 123 is close to the connection between the air inlet channel 181 and the water storage cavity 180 to prevent the water in the water storage cavity 180 from being discharged through the air inlet channel 181 and the air vent 182. The third water retaining member 123 is provided with a first air hole 123a connected to the air inlet channel 181. For example, the middle of the third water retaining member 123 is provided with the first air hole 123a, so that the gas in the air inlet channel 181 enters the water storage cavity 180 through the first air hole 123a, thereby improving the problem of the water storage cavity 180 spraying water to the water outlet channel 162. In some embodiments, the first air hole 123a is provided in plurality, such as two, three or four, and the plurality of first air holes 123a are arranged at intervals on the third water retaining member 123.

[0081] In some embodiments, the third water retaining member 123 is connected to the first sheet 111 and / or the second sheet 112, the third water retaining member 123 is spaced apart from the side plate 115, an air passage is formed between the middle portion of the third water retaining member 123 and the side plate 115, and a first air hole 123a is formed between an end portion of the third water retaining member 123 and the side plate 115. In some embodiments, two first air holes 123a are provided, that is, both ends of the third water retaining member 123 are spaced apart from the side plate 115 to form the first air holes 123a.

[0083] In some embodiments, see Figure 1 as well as Figure 2 The respirator 100 also includes a water inlet pipe 140 and a water outlet pipe 150. The water inlet pipe 140 is connected to the shell 110 through a water inlet 165. The tube cavity of the water inlet pipe 140 is arranged at an acute angle or a right angle to the first channel connected to the water inlet. The water outlet pipe 150 is connected to the shell 110 through a water outlet 166.

[0085] For example, the water inlet channel 161 is provided with a steady flow section 163. Fig.10 The water inlet water path, water inlet overflow path and anti-siphon air path of the respirator 100 provided in this application are as follows:

[0086] Water inlet waterway: Water flows through the water inlet 165 and the steady flow section 163 of the water inlet channel 161 in sequence, then enters the accommodating cavity 170 and acts on the impeller 131 of the water volume detection component 130, causing the impeller 131 to rotate. The rotating impeller 131 drives the magnetic ring 133 to rotate, and the Hall element 132 senses the magnetic ring 133 and sends a pulse signal to measure the number of rotations of the magnetic ring 133. The water flows to the water outlet channel 162 along with the rotating impeller 131. The water in the water outlet channel 162 is discharged along the water outlet 166 after being buffered by the buffer 125.

[0087] Water inlet overflow path: When the amount of water in the water outlet channel 162 is too large, the water will flow along the connecting port 183 to the water storage cavity 180 for temporary storage. When the amount of water in the water outlet channel 162 is too small, the water in the water storage cavity 180 will flow back to the water outlet channel 162 through the connecting port 183.

[0088] Anti-siphon air path: air enters the water storage cavity 180 through the air vent 182 and the air inlet 122a of the second water retaining member 122, and then flows along the connecting port 183 to the water outlet channel 162, so as to prevent the water in the dishwasher water cup from siphoning into the respirator or even the municipal water network.
