Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a switch assembly and a household appliance. Background Art

[0002] As a household appliance, a cooling fan is an air conditioner that uses the principle of water evaporation and heat absorption to output relatively low-temperature cold air to cool down the air. In order to ensure that there is enough water for evaporation and heat absorption, the cooling fan is usually equipped with a water tank, which is movably arranged on the body through a water tank switch. When the water tank needs to be removed, the operator presses down the buckle of the water tank switch to disengage the buckle, lifts up and pulls out the water tank to change the water. However, in the cooling fan of the related art, there is a problem that the removal process of the water tank is relatively inconvenient, which affects the user's experience. Summary of the invention

[0003] Based on this, it is necessary to provide a switch assembly and household appliance that are easy to disassemble in order to solve the problem of inconvenient water tank disassembly in the related art.

[0005] The switch assembly includes a stopper and a push assembly that movably cooperates with the water tank. The stopper is arranged on the cavity wall of the installation cavity. The push assembly has a locking position that cooperates with the stopper and an unlocking position that cooperates with the stopper to release the stopper.

[0006] The pushing assembly can be moved to an unlocking position in a first direction or a locking position in a second direction opposite to the first direction under the drive of an external operating end. The first direction is a direction away from a first cavity wall, and the first cavity wall is a cavity wall of the installation cavity for supporting a water tank.

[0007] The pushing assembly can be moved to the unlocking position in the first direction under the drive of the external operating end, so the operator's operating end, such as the hand, can operate the pushing assembly, and since the pushing assembly moves to the unlocking position in the first direction, the first direction is the direction away from the first cavity wall, that is, the unlocking operation of the switch assembly is the same as the direction and trend of picking up the water tank and moving it out of the installation cavity. Therefore, while the unlocking operation is being performed, the water tank can also be pulled out simultaneously, making the disassembly process of the water tank relatively simple and labor-saving.

[0008] In some embodiments, a receiving chamber is constructed in the water tank; the pushing assembly includes a pushing body, an extension arm disposed on the pushing body, and a limiting portion disposed on the extension arm;

[0055] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 According to some embodiments of the present application, the switch assembly 100 is used to movably set the water tank 210 on the body 230 of the household appliance 200. The side wall of the body 230 is configured with an installation cavity 231 with an open opening, and the installation cavity 231 accommodates the water tank 210.

[0056] The switch assembly 100 includes a stopper 110 and a push assembly 120 that movably cooperates with the water tank 210. The stopper 110 is arranged on the cavity wall of the installation cavity 231. The push assembly 120 has a locking position that cooperates with the stopper 110 and an unlocking position that releases the stopper 110.

[0057] The push assembly 120 can be driven by the external operating end to move to the unlocking position in the first direction F, or can be moved to the locking position in the second direction S opposite to the first direction F. The first direction F is a direction away from the first cavity wall 233. The first cavity wall 233 is a cavity wall of the installation cavity 231 for supporting the water tank 210.

[0058] The pushing assembly 120 can be moved to the unlocking position in the first direction F driven by the external operating end, so the operator's operating end, such as the hand, can operate the pushing assembly 120, and since the pushing assembly 120 moves to the unlocking position in the first direction F, the first direction F is the direction away from the first cavity wall 233, that is, the unlocking operation of the switch assembly 100 is the same as the direction and trend of picking up the water tank 210 and moving it out of the installation cavity 231. Therefore, while the unlocking operation is being performed, the water tank 210 can also be pulled out simultaneously, making the disassembly process of the water tank 210 relatively simple and labor-saving.

[0059] Furthermore, the water tank 210 can be plugged in and out of the first cavity wall 233, and the angle between the first direction F and the direction in which the water tank 210 is pulled out relative to the first cavity wall 233 can be less than ninety degrees, which means that the first direction F and the direction in which the water tank 210 is pulled out have the same direction and the same trend. In addition, the stopper 110 can be provided on the second cavity wall 232 of the installation cavity 231.

[0060] In the present application embodiment, combined Figure 3 , Figure 5 and Figure 7 The water tank 210 has an accommodating chamber 211 therein. The pushing assembly 120 includes a pushing body 121, an extension arm 122 disposed on the pushing body 121, and a stopper 123 disposed on the extension arm 122. The pushing body 121 is movably disposed in the accommodating chamber 211.

[0061] In some embodiments, a first opening 235 is provided on the wall of the water tank 210 facing the stopper 110. A retaining edge 2151 is provided on the other side of the accommodating cavity 211 away from the first opening 235 to limit the movement of the pushing body 121 in the second direction S.

[0062] Furthermore, the extending arm 122 and the limiting portion 123 extend out of the accommodating cavity 211 from the first opening 235 .

[0063] like Figure 5As shown, the stopper 110 is constructed as a block-shaped member protruding from the wall of the installation cavity 231. When the push assembly 120 is in the locking position, the stopper 110 is blocked on the side of the limit portion 123 close to the opening. It can be understood that Figure 5 The illustrated position is only one of the locked positions. The push assembly 120 can be in any position as long as it is not in the unlocked position. Figure 2 The elastic reset member 220 shown moves downward, so that the stopper 110 is blocked at the side of the limiting portion 123 close to the opening.

[0064] With such arrangement, most of the structure of the pushing assembly 120 is accommodated in the accommodating cavity 211, so that the limiting portion 123 serving as a stopper extends out of the accommodating cavity 211, and most of the structure of the switch assembly 100 is accommodated inside the water tank 210, which is more beautiful.

[0065] Furthermore, a receiving chamber 211 is formed in the water tank 210, and an operating port 212 communicating with the receiving chamber 211 is also provided on the outer wall of the water tank 210. Thus, it is convenient for an external operating end to enter the receiving chamber 211 through the operating port 212 to operate the pushing assembly 120.

[0066] Furthermore, combined with Figure 2 , Figure 3 and Figure 7 , the number of the stopper 110 , the extension arm 122 , the limiting portion 123 and the first opening 235 are all two.

[0067] The two extension arms 122 are arranged opposite to each other, and the two limit portions 123 are respectively connected to the opposite surfaces of the two extension arms 122. In some embodiments, the stopper 110 can be located on the side wall of the installation cavity 231. Exemplarily, the installation cavity 231 can also include a second cavity wall 232 arranged opposite to the first cavity wall 233. The stopper can be located on the second cavity wall 232.

[0068] In a specific implementation, the second cavity wall 232 includes a second cavity wall body 2321 and a flange portion 2320 provided on the second cavity wall body, and the two stoppers 110 are connected to opposite sides of the flange portion 2320 to correspond to the two limiting portions 123 one by one.

[0069] When the number of the stopper 110, the extension arm 122, the limiting portion 123 and the first opening 235 is two, the two extension arms 122 can be set on both sides of the pushing body 121, and the two limiting portions 123 can also be set on both sides of the pushing body 121. In this way, the stopper 110 can be cooperated with both sides of the pushing body 121 at the same time, and the stopping effect is better.

[0070] In a specific implementation, the limiting portion 123 may be a columnar structure. The first opening 235 may guide the corresponding extension arm 122 .

[0071] By way of example, the number of the first openings 235 may be two.

[0072] In the present application, refer to Figure 2 and Figure 7 , there is a gap between the stopper 110 and the second cavity wall body 2321. When the push assembly 120 is in the unlocking position, the position of the limit portion 123 along the first direction F corresponds to the gap, the limit portion 123 is located above the stopper 110, and can move horizontally outward from the gap to escape from the stopper 110, thereby releasing the lock with the stopper 110. Figure 5 When the pushing assembly 120 is located at the locking position, the position of the limiting portion 123 corresponds to the stopper 110 and is blocked by the stopper 110 and cannot move outside the installation cavity 231 .

[0073] With such arrangement, when the pushing assembly 120 is in the unlocking position, when the operator drives the water tank 210 to be separated from the installation cavity 231, the limiting portion 123 can be separated from the spaced position without affecting the separation of the water tank 210. When the pushing assembly 120 is in the locking position, the limiting portion 123 is stopped by the stopper 110, and the water tank 210 cannot be separated from the installation cavity 231.

[0074] Continue to refer to Figure 5 In order to facilitate the water tank 210 to enter the installation cavity 231, the surface of the stopper 110 is further provided with an inclined surface 111, and the inclined surface 111 is inclined in the direction in which the water tank 210 enters the installation cavity 231.

[0075] Further, refer to Figure 2 and Figure 3 The switch assembly 100 further includes an elastic reset member 220, which is disposed between the push assembly 120 and the cavity wall of the accommodating cavity 211 and always applies an elastic force toward the second direction to the push assembly 120. In this way, the elastic reset member 220 always applies an elastic force to the push assembly 120, so that the switch assembly 100 is always in a long-closed state when no external force is applied.

[0076] By providing the inclined surface 111 on the surface of the stopper 110, the limiting part 123 can be guided to move to the locking position. Specifically, when the top of the water tank 210 is pushed into the fuselage 230, the limiting part 123 of the pushing assembly 120 contacts the inclined surface 111 on the stopper 110. Under the action of the horizontal thrust, the limiting part 123 will move upward along the inclined surface 111. During this process, the elastic reset member 220 is gradually compressed. When the limiting part 123 moves to the top of the inclined surface 111, it continues to move away from the stopper 110 and enters the rear side of the stopper 110. At this time, the pushing assembly 120 moves downward (moves in the second direction S) under the elastic force of the elastic reset member 220 until the bottom of the pushing body 121 abuts against the bottom of the accommodating chamber 211. At this time, the limiting part 123 and the stopper 110 are stopped and matched, and the stopper 110 is blocked on the outside of the limiting part 123.

[0077] In some embodiments, the pushing assembly 120 further includes a mounting post 124 disposed on the pushing body 121, and the mounting post 124 and the extension arm 122 are located on the same side of the pushing body 121. A receiving groove 2110 is provided at a position of the inner wall of the accommodating cavity 211 corresponding to the mounting post 124. One end of the elastic reset member 220 is sleeved on the mounting post 124, and the other end is accommodated in the receiving groove 2110. In this way, the elastic reset member 220 can be better limited. In other embodiments, the receiving groove 2110 can also be provided on the pushing body 121, and the mounting post 124 can be provided on the inner wall of the accommodating cavity 211.

[0078] The elastic return member 220 may be, for example, a compression spring.

[0079] Further, refer to Figure 6 and Figure 8 The water tank 210 includes a water tank body 214 , a water tank cover 215 and a baffle 216 .

[0080] The water tank cover 215 is disposed on the top of the water tank body 214 , and a mounting groove 2150 is constructed in the water tank cover 215 .

[0081] The baffle plate 216 is disposed on the top of the water tank body 214 and is disposed on one side of the slot of the installation slot 2150 . The baffle plate 216 and the water tank cover 215 together enclose the accommodating cavity 211 . The operating port 212 is disposed on the baffle plate 216 .

[0082] In this way, the pushing body 121 is installed into the mounting groove 2150 from the notch of the mounting groove 2150 . After the water tank cover 215 is installed on the water tank body 214 , the baffle 216 can limit the pushing assembly 120 together with the water tank cover 215 .

[0083] Furthermore, combined with Figure 3 and Figure 8The pushing body 121 is provided with a pushing groove 125 , and the notch of the pushing groove 125 is arranged corresponding to the operating port 212 , so that a human hand can enter the accommodating cavity 211 through the operating port 212 and the notch of the pushing groove 125 .

[0084] The wall portion of the push groove 125 close to the extension arm 122 is formed as a push surface 1250 for an external operating end to perform an unlocking operation. Figure 8 In the example shown in FIG. 1 , the push surface 1250 is configured as a flat surface.

[0085] Or refer to Fig. 9 In another possible implementation manner, a recessed portion 1251 recessed toward one side of the stopper 110 is provided on the pushing surface 1250 .

[0086] When the recessed portion 1251 is provided, it is convenient for a person's fingers to extend into the recessed portion 1251 to operate the pushing surface 1250. Compared with a flat pushing surface 1250, the fingers are locked in the recessed portion 1251 and are not prone to relative slippage on the pushing surface 1250, thereby making the pushing operation more reliable.

[0087] Furthermore, combined with Figure 2 and Figure 8 , a notch is provided on the wall of the installation groove 2150 near the water tank body 214. A retaining edge 2151 is also defined on the wall. In other words, the bottom of the water tank cover 215 is set as a hollow structure, which can save raw materials, reduce weight, and facilitate injection molding of the water tank cover 215. At this time, the installation groove 2150 is connected to the inside of the water tank body 214 through the notch.

[0088] Further, the inner surface of the baffle 216 facing the water tank cover 215 is provided with a protruding rib 2160. The protruding rib 2160 abuts against the end of the water tank cover 215. In this way, the movement of the water tank cover 215 along the first direction F is limited by the protruding rib 2160.

[0089] In the present application embodiment, combined Figure 1 , Figure 7 When the push assembly 120 is in the unlocking position, the stopper 110 and the push assembly 120 are released from the stopper cooperation, and the water tank 210 can enter and exit the installation cavity 231 from the side of the body 230 through the opening of the installation cavity 231. Figure 1 , Figure 5 When the push assembly 120 is in the locking position, part of the push assembly 120 extends out of the accommodating cavity 211 and stops with the stopper 110. At this time, the stopper 110 blocks the outside of the push assembly 120 to prevent the water tank 210 from leaving the installation cavity 231.

[0090] Continue to refer to Figure 1, the water tank 210 can be plugged and unplugged with the first cavity wall 233. In specific implementation, the bottom of the water tank 210 is provided with a water tank liquid opening 213, and the first cavity wall 233 of the fuselage 230 is provided with a fuselage liquid opening 234. The water tank liquid opening 213 and the fuselage liquid opening 234 can be plugged and unplugged with a one-way valve. Since the pull-out direction of the water tank 210 relative to the first cavity wall 233 is the same as the unlocking direction of the operator, Figure 1 In the example, the pulling-out direction can be upward, and the first direction F is also upward, so when the water tank 210 is lifted, the valve body of the one-way valve will be closed in a shorter time, which can reduce the water leakage when the water tank liquid port 213 and the body liquid port 234 are separated from each other to a certain extent, thereby improving the user experience.

[0091] Reference Figure 1 The embodiment of the present application further provides a household appliance 200, which can be a cooling fan or other appliances that require a water tank. The household appliance 200 can include the switch assembly 100, a body 230 and a water tank 210.

[0092] Combine the following Figure 1-Figure 8 The working process of the switch assembly 100 of the present application in the household appliance 200 is described.

[0093] When the water tank 210 needs to be taken out, the push body 121 is pushed upwards by hand. During this process, the push body 121 overcomes the elastic force of the elastic reset member 220 and moves along the first direction F. When the limiting portion 123 on the push assembly 120 is higher than the body stopper 110, the limiting portion 123 and the stopper 110 are released from the stopper. The limiting portion 123 can be separated from the gap between the stopper 110 and the second cavity wall body 2321. At this time, the water tank 210 can be pulled outward from the installation cavity 231.

[0094] When the water tank 210 needs to be installed, the bottom of the water tank 210 is first placed on the first cavity wall 233 of the fuselage 230. Then the top of the water tank 210 is directly pushed horizontally into the installation cavity 231 of the fuselage 230 to complete the installation. Specifically, when the top of the water tank 210 is pushed into the fuselage 230, the limiting portion 123 of the pushing assembly 120 contacts the inclined surface 111 on the stopper 110. Under the action of the horizontal thrust, the limiting portion 123 will move upward along the inclined surface 111. During this process, the elastic reset member 220 is gradually compressed. When the limiting portion 123 moves to the top of the inclined surface 111, it continues to move away from the stopper 110 and enters the rear side of the stopper 110. At this time, the pushing assembly 120 moves downward (moves in the second direction S) under the action of the elastic force of the elastic reset member 220 until the bottom of the pushing body 121 abuts against the retaining edge 2151. At this time, the limiting portion 123 cooperates with the stopper 110 , and the stopper 110 is blocked at the outside of the limiting portion 123 . At this time, the water tank 210 is positioned in the installation cavity 231 , thereby achieving the function of locking the water tank 210 .
