Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of electrical appliances, and particularly relates to a water softener and an electrical appliance with the same. BACKGROUND

[0002] At present, the water used by the dish washer is directly tap water, which contains a large amount of calcium and magnesium ions, i.e. the so-called "hard water". When the water with high hardness enters the dish washer, the calcium and magnesium ions in the water are easy to form scale on the inner wall because the electrical appliance needs to be heated to a certain temperature, and the water with a certain temperature collides with the inner wall with a lower temperature. Therefore, in order to prevent scale, the dish washer needs to be equipped with a water softener to soften the water entering the dish washer, thereby preventing scale. The water softener generally uses ion exchange resin to soften water. After a certain amount of water is softened by the ion exchange resin, the ion exchange resin gradually loses the softening ability. At this time, salt water is needed to displace the calcium and magnesium ions near the ion exchange resin, i.e. regeneration of the water softener.

[0003] In the water softener, a salt chamber, a resin chamber and a water inlet pipeline are included, a circular salt adding port is formed on the salt chamber, and a threaded cover plug is detachably fixed at the salt adding port. When salt needs to be added to the salt chamber, the cover plug is opened, and salt is added through the salt adding port. However, the circular salt adding port and the salt adding port generally in the vertical plane make it necessary to use an arc-shaped shovel or a funnel-shaped tool when adding salt, which makes the operation of adding salt inconvenient. In addition, the cover plug is often lost after being detached, and occupies space after being detached.

[0063] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

[0064] In the description of the present application, it should be noted that the positions or location relationships indicated by the terms "upper", "lower", "left", "right" and the like are based on the position relationship shown in the drawings, and the direction in which the salt cover is opened is "front", and vice versa. The terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance; the features with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0065] In the present application, unless otherwise specifically specified and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0066] Referring to Figures 1-21, is an embodiment of the water softener proposed by the present application, a water softener comprising: a salt cavity 10, a resin cavity 20 and a pipeline 30, a salt adding opening 1 is formed on the salt cavity 10, and a salt adding cover 2 can open and close the salt adding opening 1; that is, when salt needs to be added, the salt adding cover 2 is opened, and salt is added to the salt cavity through the salt adding opening 1; when no salt is added, the salt adding cover 2 closes the salt adding opening 1. The salt adding cover 2 is hingedly arranged at the salt adding opening 1, and a locking structure for locking the salt adding cover 2 in the closed state is arranged between the salt adding cover 2 and the salt adding opening 1, and the locking structure comprises a retractable lock 3 and a lock hook 134, and the lock 3 is preferably arranged on the salt adding cover 2, and the lock hook 134 is arranged at the salt adding opening 1. By hingedly arranging the salt adding cover 2 at the salt adding opening 1, the loss after disassembly and the space occupied after disassembly of the salt adding cover 2 are avoided; the hinged arrangement of the salt adding cover 2 is beneficial to the formation of the salt adding channel into the salt cavity 10 after the salt adding cover 2 is opened, so that the salt adding operation is simple and convenient, without the need to use a special adding tool, and the adding efficiency is higher; after the hinged arrangement of the salt adding cover 2, in order to ensure the firmness of the salt adding cover in the closed state, a locking structure for locking the salt adding cover in the closed state is arranged between the salt adding cover and the salt adding opening.

[0067] After the salt adding cover 2 is rotated outwardly and opened, a salt adding channel into the salt cavity 10 is formed. When salt needs to be added, the salt adding cover 2 is operated to be rotated outwardly and opened, so that the salt adding cover 2 is inclined outwardly and a salt adding channel is formed; salt can be added to the opened salt adding cover 1, and the salt flows into the salt cavity 10 under the action of gravity and the downward force when adding salt along the salt adding channel formed by the salt adding cover 1, and the salt adding operation is completed. The salt adding operation is simple and convenient, without the need to use a special adding tool, and the adding efficiency is higher; by the hinged arrangement of the salt adding cover 2, the loss after disassembly and the space occupied after disassembly of the salt adding cover 2 are avoided. The water softener is formed by the front shell and the rear shell being buckled and sealed.

[0068] In order to more clearly describe the structure and relative position relationship of each component of the water softener, the following terms are defined: the direction in which the salt adding cover 2 is opened is "front", and vice versa; the left and right directions of the rotating axis of the salt adding cover 2; when describing the structure on the salt adding cover 2, the direction close to the symmetry axis of the salt adding cover 2 in the left and right directions is "inner", and vice versa; the plane where the salt adding opening 1 is located is a vertical plane.

[0069] Referring to Figure 9 and Figure 11As shown, the salt-adding cap 2 has a cap body 21 and a guide plate 22 extending along the cap body 21 into the salt cavity 10. The guide plate 22 is parallel to the hinge axis of the salt-adding cap 2. The cap body 21 is flat, and the guide plate 22 extends rearward along the rear side of the cap body 21. When adding salt, the salt that falls onto the salt-adding cap 2 slides downward along the cap body 21 under the action of gravity, then moves downward along the guide plate 22, and finally falls into the salt cavity. The salt-adding channel is the path that the salt travels when adding salt. The salt-adding channel includes the cap body 2 and the guide plate 22. By setting the guide plate 22, the salt is guided into the interior of the salt cavity 10, preventing the salt from reaching the hinge axis 29 along the cap body 21 and flowing out through the gap between the salt-adding cap 2 and the salt-adding port 1. With the salt cap 2 open, the rear end of the guide plate 22 is located inside the salt chamber 10, or in other words, the rear end of the guide plate 22 is located behind the salt inlet 1; ensuring that the salt flowing out from the rear end of the guide plate 22 falls into the salt chamber 10.

[0070] To prevent salt from spilling outwards from the left and right sides of the cover 21 or guide plate 22 during the salting process, the salting cover 2 also has limiting plates 23 extending into the salt cavity along the left and right sides of the cover 21, respectively. The left and right sides of the guide plate 22 are connected to the left and right limiting plates 23, respectively. By setting the limiting plates 23, it is beneficial to improve the salting speed and prevent salt from spilling from the sides. The cover 21, guide plate 22, and limiting plates 23 define the salting channel. The limiting plates 23 are in a vertical state, or the limiting plates 23 are set in an upward and outward tilted state.

[0071] See Figure 9 and Figure 15 As shown, to ensure that the salt can move smoothly backward along the guide plate 22 after reaching it, the upper surface of the guide plate 22 has an inclined surface 221 and a first arc-shaped surface 222 extending backward along the rear end of the inclined surface 221. The inclined surface 221 helps ensure that the salt reaching the guide plate 22 moves backward along the inclined surface. The first arc-shaped surface 222 helps to change the direction of the salt's fall, avoiding excessive impact on the inner wall of the salt cavity, and also helps to shorten the length of the guide plate 2 extending backward, avoiding an increase in the thickness of the salt cavity 10. Preferably, when the salt cap 2 is open, the angle between the inclined surface 221 and the horizontal plane is 5° to 15°, and more preferably, the angle between the inclined surface 221 and the horizontal plane is 7° to 8°. The first arc-shaped surface 222 is an arc surface centered on the hinge axis of the salt cap 2.

[0072] The hinged shaft 29 of the salt cover 2 is located at the lower end of the salt cover 2, that is, the distance of the upper end of the salt cover 2 moving forward is the largest when the salt cover 2 is opened; after the salt cover 2 is opened, the salt channel with an upper opening is formed, which is beneficial to the salt adding operation. The salt opening 1 and the salt cover 2 are arranged in a matching square structure, which is beneficial to the size of the salt channel formed by the salt cover 2 being larger after the salt cover 2 is opened, facilitating the salt adding operation and ensuring the efficiency of salt adding. In order to avoid the liquid in the salt cavity 10 overflowing, the liquid level in the salt cavity 10 is arranged to be lower than the lower edge of the salt opening 1, but due to the size of the salt cover 2 being larger, the size of the salt opening 1 is also larger; therefore, the baffle 11 extending upward is arranged at the lower edge of the salt opening 1, so that the liquid level in the salt cavity 10 is not higher than the upper end surface of the baffle 11, and by arranging the baffle 11, the water capacity height in the salt cavity 10 is improved, and the possibility of salt entering the track is reduced. Of course, the guide plate 22 is located above the baffle 11, and in the opened state of the salt cover 2, the guide plate 22 is also located above the baffle 11, and the rear end surface of the guide plate 22 is behind the baffle 11. The lower end surface of the guide plate 22 is a second arc surface 223, and the second arc surface 223 is an arc surface with the hinged shaft of the salt cover 2 as the center, which is beneficial to ensure that the guide plate 22 does not contact the baffle 11 during the opening and closing process of the salt cover 2, and the guide plate 22 is located above the baffle 11; and it is also beneficial to increase the structural strength and firmness of the guide plate 22.

[0073] Referring to Figure 11 and Figure 17 As shown in the drawings, the salt cover 2 also has a hinged plate 24 extending into the salt cavity 10 along the left and right sides of the lower part of the cover body 21, that is, the hinged plate 24 extends backward; the hinged shaft 29 is arranged on the hinged plate 29, and the left and right sides of the baffle 11 are provided with backwardly extending avoidance grooves 12 for avoiding the hinged plate 24; during the opening and closing process of the salt cover 2, the hinged plate 24 moves in the avoidance groove 12; in the closed state of the salt cover 2, the hinged plate 24 is located in the avoidance groove 12. By arranging the avoidance groove 12, the hinged plate 24 is avoided, and the reduction of the highest liquid level in the salt cavity 10 is avoided. Since the avoidance groove 12 extends backward along the baffle 11, in order to avoid salt falling into the avoidance groove 12 during salt adding, one is to arrange the guide plate 22 to extend backward for a relatively long length, so that the rear end surface of the guide plate 22 is located behind the avoidance groove 12 after the salt cover 2 is opened; the other is to arrange the salt channel to be located inside the avoidance groove 12, that is, the salt channel does not pass above the avoidance groove 12, that is, the limiting plate 23 is arranged inside the avoidance groove 12, or the avoidance groove 12 is located outside the plane where the limiting plate 23 is located, that is, outside in the left and right directions away from the center of the salt cover 2. Two avoidance grooves 12 are arranged on the left and right sides of the baffle 11, and the limiting plate 23 also has left and right two, the left avoidance groove 12 is located on the left side of the left limiting plate 23, and the right avoidance groove 12 is located on the right side of the right limiting plate 23.

[0074] For the limit structure of the closing to position of the salt adding cover 2, a first limit rib 26 extending in the left-right direction is arranged at the rear end of the hinged plate 24, and the first limit rib 26 cooperates with the avoiding groove 12 to limit the closing to position of the salt adding cover 2; that is, after the salt adding cover 2 is closed to position, the first limit rib 26 is in contact with the groove bottom of the avoiding groove 12. The rear end of the guide plate 22 can also be arranged to be in contact with the rear wall of the salt cavity 10 after the salt adding cover 2 is closed to position; that is, after the salt adding cover 2 is closed to position, the first limit rib 26 is in contact with the groove bottom of the avoiding groove 12 and / or the upper rear end of the guide plate 22 is in contact with the rear wall of the salt cavity 10; the first limit rib 26 can be arranged to be in contact with the groove bottom of the avoiding groove 12, and at the same time, the upper rear end of the guide plate 22 is in contact with the rear wall of the salt cavity 10, so that the upper part and the lower part of the salt adding cover 2 are both limited after being closed, thereby ensuring the limiting effect after being closed to position.

[0075] For the limit structure of the closing to position of the salt adding cover 2, a first limit rib 26 extending in the left-right direction is arranged at the rear end of the hinged plate 24, and the first limit rib 26 cooperates with the avoiding groove 12 to limit the closing to position of the salt adding cover 2; that is, after the salt adding cover 2 is closed to position, the first limit rib 26 is in contact with the groove bottom of the avoiding groove 12. The rear end of the guide plate 22 can also be arranged to be in contact with the rear wall of the salt cavity 10 after the salt adding cover 2 is closed to position; that is, after the salt adding cover 2 is closed to position, the first limit rib 26 is in contact with the groove bottom of the avoiding groove 12 and / or the upper rear end of the guide plate 22 is in contact with the rear wall of the salt cavity 10; the first limit rib 26 can be arranged to be in contact with the groove bottom of the avoiding groove 12, and at the same time, the upper rear end of the guide plate 22 is in contact with the rear wall of the salt cavity 10, so that the upper part and the lower part of the salt adding cover 2 are both limited after being closed, thereby ensuring the limiting effect after being closed to position.

[0076] Referring to FIGS. 1, 2 and 3, Figure 11 and Figure 17 For the limit structure of the closing to position of the salt adding cover 2, a first limit rib 26 extending in the left-right direction is arranged at the rear end of the hinged plate 24, and the first limit rib 26 cooperates with the avoiding groove 12 to limit the closing to position of the salt adding cover 2; that is, after the salt adding cover 2 is closed to position, the first limit rib 26 is in contact with the groove bottom of the avoiding groove 12. The rear end of the guide plate 22 can also be arranged to be in contact with the rear wall of the salt cavity 10 after the salt adding cover 2 is closed to position; that is, after the salt adding cover 2 is closed to position, the first limit rib 26 is in contact with the groove bottom of the avoiding groove 12 and / or the upper rear end of the guide plate 22 is in contact with the rear wall of the salt cavity 10; the first limit rib 26 can be arranged to be in contact with the groove bottom of the avoiding groove 12, and at the same time, the upper rear end of the guide plate 22 is in contact with the rear wall of the salt cavity 10, so that the upper part and the lower part of the salt adding cover 2 are both limited after being closed, thereby ensuring the limiting effect after being closed to position.

[0077] In order to increase the contact area of the second limiting rib 27 and the limiting rib 131, improve the stability of the open state, when the salt adding cover 2 is in the open state, the second limiting rib 27 and the limiting rib 131 are in surface contact, the included angle between the second limiting rib 27 and the cover body 21 is 30°-40°, preferably, the included angle between the second limiting rib 27 and the cover body 21 is 35°. When the salt adding cover 2 is in the open state, the included angle between the cover body 21 and the salt adding opening 1 is 35°-40°, or the included angle between the cover body 21 and the vertical surface is 35°-40°, which ensures the inclination angle of the cover body 21 and the smoothness of the salt adding channel.

[0078] A reinforcing plate 28 extending in the left-right direction is arranged at the upper end of the hinge plate 24, the lower end of the second limiting rib 27 is connected to the reinforcing plate 28, and the upper end of the second limiting rib 27 is connected to the upper end of the limiting plate 23. A connecting plate 25 is arranged between the hinge plate 24 and the limiting plate 23, wherein the limiting plate 23, the connecting plate 25, and the hinge plate 24 are sequentially arranged outward on the cover body 21, so that the avoiding groove 12 is located outside the plane where the limiting plate 23 is located.

[0079] Referring to FIGS. 1-3, Figure 1 and Figure 2 In order to hinge, lock and limit the open state of the salt adding cover 2, a cover frame 13 extending forward along the edge of the salt adding opening 1 is arranged, the salt adding cover 2 is hinged to the cover frame 13, and the front end surface of the cover body 21 is flush with the front end surface of the cover frame 13 when the salt adding cover 2 is in the closed state.

[0081] The salted cover 2 comprises a cover body 21, a rear end surface of the cover body 21 is provided with a rear protruding mounting cavity 20, and the lock 3 is movably arranged in the mounting cavity 20. The mounting cavity 20 is an upper opening cavity, the mounting cavity 20 is matched with the lock body 30, and the mounting cavity 20 is movably arranged in the mounting cavity 20.

[0082] Referring to Figure 6 , Figure 11 and Figure 21 , in order to realize the installation of the lock 3 to the mounting cavity 20, the lock 3 further has a clamping jaw 32 arranged downwardly from the lock body 30, a through opening 201 for the clamping jaw 32 to extend out is arranged at a lower end of the mounting cavity 20, and the clamping jaw 32 is clamped at the through opening 201. When the lock 3 is moved upwardly to the through opening 201, the lock 3 is in the maximum extension state. In order to realize the upward and downward movement of the lock 3, the lock 3 further has a lock post 33 extending downwardly from the lock body 30 and a spring 34 sleeved outside the lock post 33, and the spring 34 is used for resetting the lock 3 after the downward movement; the mounting cavity 20 is provided with a downward extending extension cavity 202, and the lock post 33 and the spring 34 extend into the extension cavity 202. The extension cavity 202 is arranged to facilitate accommodating the lock post 33 and the spring 34, to ensure the resetting of the lock 3, and when the lock 3 is pressed downwardly, the clamping jaw 32 also extends downwardly, and the left and right two clamping jaws 32 are located at the left and right sides of the extension cavity 202.

[0083] Referring to Figure 6 , Figure 11 and Figure 12 , the size of the lock body 30 in the front-rear and left-right directions is matched with the size of the mounting cavity 20 in the front-rear and left-right directions, and the diameter of the lock post 33 is greater than the size of the lock body 30 in the front-rear direction; in order to realize the installation of the lock 3 to the mounting cavity 20 and realize the upward and downward movement of the lock 3, an arc-shaped groove 203 in the upward and downward directions is arranged on the front-rear wall of the mounting cavity 20, and the arc-shaped groove 203 is used for avoiding the part of the lock post 33 protruding from the lock body 30 in the front-rear direction.

[0084] Referring to Figure 6 and Figure 21 As shown in the figure, in order to realize the locking and unlocking of the lock 3, the lock 3 also has a pressing part 35 extending forward along the upper end of the lock body 30 and a flange part 36 extending downward along the front end of the pressing part 35, the lock body 30, the pressing part 35 and the flange part 36 surround a containing groove 37, and the upper end of the cover body 21 can be located in the containing groove 37. By providing the pressing part 35, the unlocking operation of the lock 3 is facilitated; the pressing part 35 is inclined forward and downward, which is beneficial to the pressing operation of the operator, and the included angle between the plane where the pressing part 35 is located and the plane where the lock body 30 is located is 70°-80°; a plurality of arc-shaped protrusions arranged in parallel for increasing friction are arranged on the upper surface of the pressing part 35. In the closed state of the salt adding cover 2, the inclination angle of the pressing part 35 is the same as that of the top 132 of the cover frame 13. The lock body 30, the pressing part 35 and the flange part 36 surround the containing groove 37, and the upper end of the cover body 21 is covered in the containing groove 37, which is beneficial to play a limiting role and ensure that the lock 3 moves up and down along the cover body 21; and it is also beneficial to increase the force bearing capacity of the lock 3. When a rearward pushing force is applied to the salt adding cover 2 in the closed and locked state of the salt adding cover 2, the pushing force is transmitted between the lock body 30 and the lock hook 134; the force transmitted to the lock body 30 acts on the cover body 21 through the containing groove 37, which increases the stability and avoids damage to the lock 3; when a forward pulling force is applied to the salt adding cover 2 in the closed and locked state of the salt adding cover 2, the pulling force is transmitted between the lock lug 31 and the lock hook 134; the force transmitted to the lock lug 31 is transmitted to the containing groove 37 through the lock body 30, and then to the cover body 21 through the containing groove 37, which increases the stability and avoids damage to the lock 3.

[0085] In order to ensure that the containing groove 37 is covered at the upper end of the cover body 21, a guide groove 211 with an upper opening is arranged at the upper end of the cover body 21, and a guide block matching the guide groove 211 is arranged in the containing groove 37. The guide block is located in the guide groove 211 and moves with the lock 3, which is used for guiding and ensuring that the upper end of the cover body 21 is located in the containing groove 37, thereby increasing the ability of the lock 3 to bear the force in the forward and rearward directions.

[0086] Since the receiving groove 37 covers the upper end of the cover 21, a locking groove 135 is provided on the cover frame 13 for closing the salt cap 2. The upper end of the lock 3 is located within the locking groove 135, that is, the upper parts of the lock body 30, the pressing part 35, and the flange part 36 are located within the locking groove 135. A downwardly extending protrusion forming a locking hook 134 is provided on the rear wall of the locking groove 135. By providing the locking groove 135, it serves two purposes: firstly, it accommodates the part of the lock 3 that protrudes above the cover 21; secondly, the locking hook 134 is provided within the locking groove 135, matching the lock body 30 and the lock lug 31, thus locking the salt cap 2. In the locked state of the salt cap 2, the locking hook 134 is located within the slot 38 formed by the lock body 30 and the lock lug 31.

[0087] See Figure 7 and Figure 20 As shown, to ensure the secure locking of the hook 134 and the slot 38, when the salt cap 2 is locked, the front wall of the slot 38 is located in front of the rear wall 1351 of the locking groove 135, and the rear end face of the hook 134 cooperates with the rear end wall of the slot 38 to ensure the secure locking. The lock can only be released by pressing down on the lock 3 to move it downward. The hook 134 has a forward and downward inclined rear surface 1341. The inclination angle of the rear inclined surface 1341 of the hook 134 is the same as the inclination angle of the front end face of the lock lug 31 when the salt cap 2 is closed. The front end face of the lock lug 31 is also the rear end wall face of the slot 38, which helps to increase the contact area between the hook 134 and the lock lug 31, and increase the stability and secureness in the locked state. The front inclined surface 1342 of the locking hook 134 is connected to the rear inclined surface 1341, and the included angle between the front inclined surface 1342 and the rear inclined surface 1341 is 90°. By setting the front inclined surface 1342 and the rear inclined surface 1341 to be perpendicular, it is beneficial to increase the stability of locking and to ensure the structural strength of the locking hook 134. An arc-shaped connecting surface 1343 is provided between the front inclined surface 1342 and the rear end wall 1331 of the locking groove 135. The upper end of the locking lug 31 has an arc-shaped structure. When the salt cap 2 is closed, the upper end of the locking lug 31 contacts the front inclined surface 1342 of the locking hook 134. Under the action of the rearward thrust, the upper end of the locking lug 31 moves downward along the front inclined surface 1342 of the locking hook 134, so that the lock 3 moves downward. After the locking lug 31 passes the front inclined surface 1342, the lock 3 is reset under the action of the spring 34, so that the locking hook 134 is engaged in the slot 38. Of course, when the salt cap 2 is closed and locked, the pressing part 35 can be pressed to make the lock 3 move downward. When the salt cap 2 is closed in place, the pressing part 35 can be released to make the lock hook 134 engage in the slot 38.

[0088] The following explains how to add salt using the salt cap 2. The specific steps are as follows:

[0089] S10. Release the lock on salt cap 2;

[0090] Specifically, the pressing part 35 is pressed downward, so that the lock 3 moves downward, the spring 34 is compressed, and the lock hook 134 is disengaged from the clamping groove 38.

[0091] S20. The salt adding cover 2 is rotated forward, and the lock 3 is reset upward.
