[0002] There are three main types of dishwashers on the market: tabletop dishwashers, cabinet dishwashers, and sink-integrated dishwashers. Dishwashers are directly connected to the tap water supply. The calcium and magnesium ions contained in the tap water are easily precipitated to form scale, which affects the washing effect. For this reason, it is usually necessary to use a water softener to soften hard water and remove calcium and magnesium ions in the water to ensure the washing effect. In addition, the water intake of the dishwasher is controlled by a flow meter or a water level pressure sensor.

[0036] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0037] Embodiment 1

[0038] like Figure 1-13 As shown, in this embodiment, the water softener assembly includes a water softener 1, a first fixing assembly 2, a second fixing assembly 20, a sink 3 and a faucet 4. The sink 3 may be the inner tank of a tabletop or cabinet dishwasher and the functional tank or sink of a sink-type dishwasher, but is not limited thereto. In this embodiment, the sink 3 includes a sink 301 and a functional tank 302. The water softener 1 is fixed to the outside of the sink 301 and is fixedly connected to the sink 301 through the first fixing assembly 2; the faucet 4 is fixed to the upper part of the sink 301 and is fixedly connected to the water softener 1 and the sink 301 through the second fixing assembly 20.

[0039] like Figure 1-8 As shown, the water softener 1 includes a body 10 , a control member 11 , a sealing cover 12 , a water inlet valve 13 , a filter screen 15 , a float assembly 16 and a flow meter assembly 17 .

[0040] like Figure 1-5 As shown, the body 10 has a water inlet channel 101, a first cavity 102, a second cavity 103, a water outlet channel 104, a first overflow channel 105, an addition channel 106, a third channel 107, an overflow seat 108, a second overflow channel 109, a first overflow pipe 110 and a second overflow pipe 111. The water inlet channel 101 has a water inlet 1011, the water outlet channel 104 has a water outlet 1041, and the water outlet channel 104 is connected to the first cavity 102. The water softener 1 has two states: a softening state and a regeneration state. In the softening state, the water inlet channel 101 is connected to the first cavity 102. In the regeneration state, the water inlet channel 101 is connected to the second cavity 103, and the second cavity 103 is connected to the first cavity 102.

[0041] The control member 11 has a first state and a second state. In the first state, the water softener 1 is in a softening state, and the water inlet channel 101, the first chamber 102 and the water outlet channel 104 are connected in sequence; in the second state, the water softener 1 is in a regeneration state, and the water inlet channel 101, the second chamber 103, the first chamber 102 and the water outlet channel 104 are connected in sequence.

[0042] In other words, water in the tap water pipe enters the water inlet channel 101 through the water inlet 1011, the control component 11 is in the first state, the control component 11 connects the water inlet channel 101 and the first cavity 102, the water in the water inlet channel 101 directly enters the first cavity 102, and the sodium ions of the resin in the first cavity 102 are replaced by the calcium and magnesium ions in the inlet water to soften the hard water. The softened water enters the water outlet channel 104 and is passed into the dishwasher through the water outlet 1041 to complete the washing. Since the softening ability of the resin used as the hard water component absorption material is not permanently maintained, the resin needs to be regenerated after being used for a period of time. After the resin in the first chamber 102 has been used for a period of time, the control component 11 is in the second state, and the control component 11 connects the water inlet channel 101 and the second chamber 103. The water in the water inlet channel 101 first enters the second chamber 103 and mixes with salt water to carry sodium ions. The aqueous solution carrying sodium ions then enters the first chamber 102. The sodium ions in the mixed aqueous solution are absorbed by the resin in the first chamber 102, thereby realizing the regeneration of the resin and restoring the ability of the resin to absorb calcium and magnesium ions. At the same time, the calcium and magnesium ions in the mixed aqueous solution are also absorbed by the resin.

[0043] More specifically, if Figure 3 , 4 As shown, the body 10 further includes a first cavity water inlet channel 1021, a second cavity water inlet channel 1033, and a second cavity water outlet channel 1034. In the first state, the water inlet channel 101, the first cavity water inlet channel 1021 and the first cavity 102 are connected (as shown in FIG. Figure 3 In the second state, the water inlet channel 101, the second chamber water inlet channel 1033, the second chamber 103, the second chamber water outlet channel 1034, the first chamber water inlet channel 1021 and the first chamber 102 are connected (as shown in the arrow). Figure 4 Arrows indicate the direction of water flow).

[0044] like Figure 1 As shown, the body 10 includes a body top wall 1001 at the upper end, a body bottom wall 1003 at the lower end, and a body side wall 1002 extending in the up-down direction and connected between the top wall 1001 and the body bottom wall 1003. Figure 3-5 As shown, the walls surrounding the second cavity 103 include a second cavity top wall 1031 , a second cavity side wall 1032 , and a second cavity bottom wall 1035 . The second cavity side wall 1032 is a part of the body side wall 1002 .

[0045] The first overflow channel 105, the addition channel 106 and the addition channel opening 1060 are located at the upper part of the body 10. The addition channel wall 1061 is arranged on the body 10 and surrounds the addition channel 106. The addition channel opening 1060 includes a lower addition channel opening 1068 and an upper addition channel opening 1069. One end of the addition channel 106 is connected to the second cavity 103 through the lower addition channel opening 1068, and the other end is connected to the outside of the body 10 through the upper addition channel opening 1069. The addition channel wall 1061 is connected to the wall surrounding the second cavity 103. The body 10 is provided with an overflow port 1051, which is opened on the addition channel wall 1061. The first overflow channel 105 is arranged in a lateral direction (such as 1068) perpendicular to the up and down direction. Figure 1 The second chamber 103 is connected to the first overflow channel 105 through the overflow port 1051. The first overflow channel 105 is connected to the outside of the body 10 for discharging overflow water from the second chamber 103 when adding salt.

[0046] Specifically, the adding channel 106 is located above the second cavity 103, penetrates the second cavity top wall 1031 in the up-down direction, and the adding channel wall 1061 is connected to the second cavity top wall 1031, and the overflow port 1051 is located below the upper end surface of the adding channel wall 1061. More specifically, the adding channel 106 penetrates the main body top wall 1001 and the second cavity top wall 1031 in sequence from top to bottom in the up-down direction, the adding channel wall 1061 is connected to the main body top wall 1001 and the second cavity top wall 1031, and the overflow port 1051 is provided between the main body top wall 1001 and the second cavity top wall 1031. In other words, the main body top wall 1001 is located above the second cavity top wall 1031, the addition channel wall 1061 includes a first tube wall 1063 located between the main body top wall 1001 and the second cavity top wall 1031 and a second tube wall 1062 extending upward and protruding from the main body top wall 1001, and the overflow port 1051 is opened in the first tube wall 1063. Specifically, the overflow port 1051 is located at the upper end of the first tube wall 1063, the upper end of the overflow port 1051 is adjacent to the main body top wall 1001, and the lower end of the overflow port 1051 is above the second cavity top wall 1031. The first overflow channel 105 is located between the main body top wall 1001 and the second cavity top wall 1031.

[0047] The water softener 1 uses salt water to regenerate the resin, so that the resin can recover its ability to absorb calcium and magnesium ions. After the water softener 1 has been used for a period of time, salt needs to be added to the second chamber 103 through the addition channel 106 to ensure the concentration of salt water. It is understandable that if Figure 4As shown, the overflow port 1051 is lower than the upper adding channel port 1069. During the salt adding process, the liquid level in the adding channel 106 rises, and the salt water overflowing the lower adding channel port 1068 and being higher than the overflow port 1051 but lower than the upper adding channel port 1069 enters the first overflow channel 105 from the overflow port 1051, and the overflowed salt water is discharged to the outside of the main body 10 through the first overflow channel 105.

[0048] The water softener 1 is provided with an overflow port 1051 and a first overflow channel 105 in the body 10, and the overflow port 1051 is opened on the adding channel wall 1061, and the first overflow channel 105 is connected with the overflow port 1051 in a lateral direction perpendicular to the up and down direction, which can reduce the risk of salt particles falling into the overflow port 1051 when adding salt, thereby reducing the risk of blocking the overflow port 1051 and improving the reliability of the use of the water softener 1. At the same time, the salt water overflowing from the second chamber 103 when adding salt can be discharged more smoothly, preventing the salt water from overflowing into the washing tank 3 to corrode the washing tank 3, or overflowing onto the countertop to affect the user experience. The overflow port 1051 is provided on the adding channel wall 1061, and the size of the adding channel port 1060 can also be reduced, thereby saving space, and it is also convenient to seal the second chamber 103 and the overflow port 1051 at the same time, simplifying the operation steps of adding salt.

[0049] like Figure 3 As shown, a thread structure 1067 is provided on the outer side of the adding channel wall 1061. More specifically, a thread structure 1067 is provided on the outer side of the second pipe wall 1062 of the water softener 1.

[0050] Figure 1 , 13 As shown, the sealing cover 12 is used to open or close the second chamber 103, so as to add salt to the second chamber 103 or to close the second chamber 103 when the salt water concentration reaches the standard. Specifically, the sealing cover 12 can be used to open or close the overflow port 1051 at the same time. It can be understood that when the water softener 1 is working, the sealing cover 12 closes the overflow port 1051 and the second chamber 103, and the water in the water inlet channel 101 enters the second chamber 103 and mixes with the salt water, and the mixed aqueous solution enters the first chamber 102 to regenerate the resin; when salt needs to be added to the second chamber 103, the sealing cover 12 opens the overflow port 1051 and the second chamber 103, and the liquid level in the addition channel 106 rises when salt is added, and the salt water overflowing the lower addition channel port 1068 and higher than the overflow port 1051 but not higher than the upper addition channel port 1069 enters the first overflow channel 105 from the overflow port 1051, so as to discharge the overflow water of the second chamber 103 when salt is added.

[0051] like Figure 1As shown, the second overflow channel 109 is provided at the upper part of the body 10, and the second overflow channel 109 includes an overflow inlet 1081 and an overflow outlet 1082, and the overflow inlet 1081 and the overflow outlet 1082 are connected to the outside of the body 10, and the liquid outside the body 10 enters the second overflow channel 109 through the overflow inlet 1081, and the liquid entering the second overflow channel 109 is discharged through the overflow outlet 1082. More specifically, as Fig.10 As shown, the overflow inlet 1081 is connected to the tank overflow port 341 of the water tank 301, and the overflow outlet 1082 is connected to the downpipe (not shown). The overflow inlet 1081 can also be connected to the function tank overflow port 342 of the function tank 302, and the function tank 302 can be the inner tank of the dishwasher, but is not limited thereto.

[0052] The overflow seat 108 is provided with the second overflow channel 109. Figure 1 , 5 As shown, the overflow seat 108 extends from the side wall 1002 of the main body along a longitudinal direction perpendicular to the up-down direction and the transverse direction (eg Figure 1 The overflow seat 108 includes an overflow inlet 1081, a surrounding wall 1088 surrounding the overflow inlet 1081, and a vertical wall 1089 connected to the surrounding wall 1088 (the vertical wall 1089 is a part of the body side wall 1002). The overflow outlet 1082 can be set at the surrounding wall 1088 at the lower end. In addition, the overflow outlet 1082 can also be set at the surrounding walls 1088 on both sides in the lateral direction (as shown in FIG. Figure 1 The overflow seat 108 is located on the left or right side of the overflow seat 108. It can be understood that the overflow seat 108 is connected to the outside of the body through the overflow inlet 1081, and the liquid outside the body enters the overflow seat 108 through the overflow inlet 1081 and is discharged to the downpipe (not shown) through the overflow outlet 1082.

[0053] According to the water softener 1 of the embodiment of the present invention, a second overflow channel 109 is provided in the body 10 of the water softener 1, and the overflow inlet 1081 of the second overflow channel 109 is connected to the outside of the body 10, and the overflow outlet 1082 of the second overflow channel 109 is connected to a sewer pipe (not shown), so that the water softener 1 can soften hard water and discharge external overflow water, and occupies a small space, thereby realizing reasonable use of space.

[0054] A first communication port 1052 is formed at one end of the first overflow channel 105 away from the overflow port 1051 , and the first overflow channel 105 is connected to the overflow seat 108 through the first communication port 1052 .

[0055] The upper part of the vertical wall 1089 of the overflow seat 108 is provided with a second communication port 1083 and a communication groove 1080 located between the first communication port 1052 and the second communication port 1083. The first overflow channel 105 is connected to the outside of the body 10 through the first communication port 1052, the communication groove 1080, the second communication port 1083 and the overflow outlet 1082. It can be understood that during the salt addition process, the salt water overflowing the lower addition channel port 1068 enters the first overflow channel 105 through the overflow port 1051, and then enters the overflow seat 108 through the first communication port 1052, the communication groove 1080, the second communication port 1083, and then is discharged to the sewer pipe (not shown) through the overflow outlet 1082.

[0056] The overflow seat 108 is provided with a baffle 1087 extending outward from the vertical wall 1089 in the longitudinal direction. The baffle 1087 is arranged between the second connecting port 1083 and the overflow outlet 1082 to prevent foam and the like from the sewer pipe (not shown) from entering the first overflow channel 105 and entering the second chamber 103 through the overflow port 1051 to contaminate the salt water.

[0057] The overflow seat 108 is provided with a fixing column 1084 extending outwardly from the vertical wall 1089 in the longitudinal direction, and the fixing column 1084 is provided with a threaded structure (not shown). More specifically, the overflow seat 108 is provided with a reinforcing rib 1085 extending outwardly from the vertical wall 1089 in the longitudinal direction, and the reinforcing rib 1085 is connected to the vertical wall 1089 and the surrounding wall 1088. Furthermore, at least part of the reinforcing rib 1085 is connected to the fixing column 1084. The fixing column 1084 is provided with an internal threaded hole 1091. More specifically, the fixing column is provided with a metal insert 1086 with an internal threaded structure.

[0058] One end of the first overflow pipe 110 is connected to the second overflow channel 109 through the overflow outlet 1082, and the other end of the first overflow pipe 110 is connected to the downpipe (not shown). Specifically, the first overflow pipe 110 extends in the up-down direction. It can be understood that the liquid from the water tank 301 entering the overflow seat 108 through the water tank overflow port 341 and the overflow inlet 1081, and the salt-added overflow water from the body 10 entering the overflow seat 108 through the overflow port 1051 and the first overflow channel 105, can be discharged to the downpipe (not shown) through the overflow outlet 1082 and the first overflow pipe 110.

[0059] The body 10 is provided with a second overflow pipe 111 connected to the first overflow pipe 110, one end of the second overflow pipe 111 is communicated with the first overflow pipe 110, and the other end of the second overflow pipe 111 is communicated with the function tank overflow port 342 of the function tank 302. Specifically, the axial directions of the first overflow pipe 110 and the second overflow pipe 111 are perpendicular. It can be understood that the overflow water of the function tank 302 enters the first overflow pipe 110 through the second overflow pipe 111, and then is discharged to the sewer pipe (not shown).

[0060] The main body 10 is provided with a third channel 107 and a third channel wall 1071 surrounding the third channel 107. The third channel 107 penetrates the main body top wall 1001 in the up and down directions. The third channel wall 1071 is connected to the second cavity side wall 1032, and the third channel 107 is not connected to the second cavity 103, and is used as a placement channel for external components.

[0061] Specifically, the addition channel 106 and the third channel 107 are adjacent, and the third channel wall 1071 is at least partially connected to the addition channel wall 1061. It can be understood that by providing the third channel 107 connected to the addition channel 106 in the body 10 of the water softener 1, it can be used as a placement channel for the faucet water inlet pipe 41. In other words, the faucet water inlet pipe 41 can be placed in the third channel 107 and pass through the body top wall 1001. The placement channel of the faucet water inlet pipe 41 is integrated into the water softener 1, which reasonably utilizes the space of the water softener 1.

[0062] The water inlet valve 13 is installed at the water inlet 1011. Figure 7 , 8 As shown, the water inlet valve 13 includes a valve body 131, a check valve core 132, an O-ring 133, an elastic member 134 and a base 135. The valve body 131 is provided with an inlet 130. The O-ring 133 is sleeved on the valve portion 1322 of the check valve core 132 from right to left. The elastic member 134 is sleeved on the left valve stem 1321 of the check valve core 132 from left to right. The check valve core 132 is inserted into the valve body 131 from left to right. The left end of the check valve core 132 is connected to the base 135. In other words, the water inlet valve 13 is provided with a valve body 131, an O-ring 133, a check valve core 132, an elastic member 134 and a base 135 in sequence from right to left. When water is entering, the check valve core 132 is opened and water enters normally; since air is inevitably entrained in the incoming water, when siphoning occurs, the O-ring 133 fits tightly with the valve body 131 under the action of the siphon negative pressure to form a seal, preventing the water in the water inlet channel 101 from being siphoned into the water supply pipe.

[0063] like Figure 2 , 3 As shown, filter screens 15 are installed at the upper and lower ends of the first cavity 102 , and the filter screens 15 can prevent the resin in the first cavity 102 from leaking, thereby ensuring the stability of the resin components.

[0064] like Figure 2-4As shown, a float assembly 16 is provided in the second chamber 103 for detecting the salinity of the brine in the second chamber 103. The float assembly 16 and the float 161 are suitable for being suspended in a salt solution having a rated density. In other words, as long as the density of the salt solution is maintained at the rated density, the float 161 will be suspended in the salt solution. If the density of the salt solution is lower than the rated density, the float 161 will sink. The "rated density" is a set value, which is based on whether the sodium content in the salt solution is sufficient to supply the absorption of the resin to achieve the regeneration of the resin. When the density of the salt solution is lower than the set value, salt needs to be added to the salt solution.

[0065] like Figure 2 , 3 As shown, the main body 10 also includes a flow meter installation cavity 171 connected to the water inlet channel 101. The flow meter assembly 17 is installed in the flow meter installation cavity 171, and is used to measure the water inlet flow in the water inlet channel 101. The amount of water entering the water inlet channel 101 through the water inlet 1011 can be measured in real time, and the amount of water entering the water inlet channel 101 through the water inlet 1011 can be effectively prevented. Excessive water flow in the water inlet channel 101 can be prevented.

In other words, the adding channel wall 1061 of the water softener 1 is hidden in the faucet 4, which saves space and beautifies the appearance. When salt needs to be added, the faucet is removed, and part of the faucet water inlet pipe 41 is pulled out of the third channel 107 to expose the adding channel wall 1061, and the salt adding operation is performed.

[0075] Embodiment 2

[0076] The main difference between the second embodiment and the first embodiment lies in the addition channel 106 of the water softener 1 .

[0077] like Figure 14-16 As shown, in this embodiment, the main body 10 is provided with a partition 1064 extending in the up and down directions and connected to the adding channel wall 1061, the partition 1064 divides the adding channel 106 into a first channel 1065 and a second channel 1066, the first channel 1065 is connected to the second cavity 103, the second channel 1066 is connected to the overflow port 1051 and the lower end is closed, and the upper end surface of the partition 1064 is lower than the upper adding channel port 1069.

[0078] It can be understood that the upper end surface of the partition 1064 is lower than the upper addition channel opening 1069. During the salt adding process, the liquid level in the first channel 1065 rises, and the brine overflows the lower addition channel opening 1068 and is higher than the upper end surface of the partition 1064 but lower than the upper addition channel opening 1069, enters the second channel 1066, enters the first overflow channel 105 from the overflow port 1051, and then the overflowed brine is discharged to the outside of the main body 10 through the first overflow channel 105.

[0079] Compared with the first embodiment, the second embodiment has the sealing cover 12 only used to open or close the second cavity 103, and the overflow port 1051 does not need to be sealed, so the operation is easier and the sealing effect is better.

[0080] The other structures and effects of the second embodiment are the same as those of the first embodiment, and will not be described in detail here.

[0081] Embodiment 3

[0082] The main difference between the third embodiment and the first embodiment lies in the anti-siphon structure of the water softener 1 .

A breathing port (not shown), a leakage cavity 142 and a leakage port 141 are provided on the upper part of the body 10. The breathing port is opened on the wall surrounding the water inlet channel 101. The leakage cavity 142 is located between the water inlet channel 101 and the water outlet channel 104 along the up and down direction. The water inlet channel 101 is connected to the leakage cavity 142 through the breathing port, and the leakage cavity 142 is connected to the atmosphere through the leakage port 141. Specifically, the leakage cavity 142 is connected to the overflow seat 108 through the leakage port 141. The water softener 1 also includes a breather insert 14, which is arranged in the water inlet channel 101 and corresponds to a breathing port (not shown). Since air is inevitably entrained in the incoming water, in order to balance the air pressure in the water inlet channel 101 and prevent siphoning, a breather insert 14 is arranged in the water inlet channel 101. The breather insert 14 is embedded in the water inlet channel 101, and a breathing port (not shown) corresponding to the breather insert 14 is opened on the wall surrounding the water inlet channel 101, which can discharge the gas in the incoming water and balance the air pressure of the water channel in the device.

[0084] The other structures and effects of the third embodiment are the same as those of the first embodiment, and will not be described in detail here.

[0085] Embodiment 4

[0086] The main difference between the fourth embodiment and the first embodiment lies in the third channel 107 of the water softener 1 .

[0087] like Fig.18 As shown, in this embodiment, the third channel 107 is not adjacent to the adding channel 106, and the third channel wall 1071 is not connected to the adding channel wall 1061, that is, the third channel 107 is separately arranged from the adding channel 106. Fig.19 , 20 As shown, the adding channel wall 1061 of the water softener 1 passes through the third through hole 35 of the water tank 301 and is fixedly connected to the sealing cover 12. Specifically, a third fixing member 26 is sandwiched between the sealing cover 12 and the groove edge portion 33 of the water tank 301. The faucet water inlet pipe (not shown) can pass through the third channel 107, and the faucet 4 is fixedly connected to the third through hole 35 of the water tank 301.

[0088] The other structures and effects of the fourth embodiment are the same as those of the first embodiment, and will not be described in detail here.
