Description

TECHNICAL FIELD

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

[0002] As a kind of household appliance, cold fan is an air conditioner for cooling by using the principle of water evaporation and heat absorption to output cold air with relatively low temperature. In order to ensure sufficient water for evaporation and heat absorption, the cold fan is usually equipped with a water tank, which is movably arranged on the machine body through a water tank switch. When the water tank needs to be disassembled, the operator presses the buckle of the water tank switch downward to make the buckle disengage, lifts up and pulls out the water tank to replace the water. However, in the related art, the disassembly process of the water tank is relatively inconvenient, which affects the user experience. CONTENT OF THE UTILITY MODEL

[0003] Therefore, it is necessary to provide a switch assembly and a household appliance which are simple to disassemble in view of the problem of inconvenient disassembly of the water tank in the related art.

The push assembly has a locking position in stopper cooperation with the stopper and an unlocking position in non-stopper cooperation with the stopper.

[0006] The push assembly can be moved to the unlocking position in the first direction under the driving of the external operating end, or can be moved to the locking position in the second direction opposite to the first direction. The first direction is the direction away from the first cavity wall, and the first cavity wall is the cavity wall of the mounting cavity for bearing the water tank.

[0007] The push assembly can be moved to the unlocking position in the first direction under the driving of the external operating end. Therefore, the operating end, such as the hand, of the operator can operate the push assembly. Since the push assembly is moved 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 tendency of lifting up and moving out the water tank from the mounting cavity. Therefore, the pulling-out action of the water tank can be synchronized with the unlocking operation, so that the disassembly process of the water tank is simple and labor-saving.

[0055] Referring to Figure 1 , Figure 2 , Figure 4 , Figure 5 According to some embodiments of the present application, the switch assembly 100 is used to movably arrange the water tank 210 on the body 230 of the household appliance 200, and the side wall of the body 230 is configured with a mounting cavity 231 with an opening, and the mounting cavity 231 contains the water tank 210.

[0056] The switch assembly 100 comprises a stopper 110 and a pushing assembly 120 movably coupled with the water tank 210. The stopper 110 is arranged on a cavity wall of the mounting cavity 231. The pushing assembly 120 has a locking position for locking with the stopper 110 and an unlocking position for unlocking with the stopper 110.

[0057] The pushing assembly 120 is capable of moving to the unlocking position in a first direction F or moving to the locking position in a second direction S opposite to the first direction F under the driving of the external operation end. The first direction F is a direction away from a first cavity wall 233. The first cavity wall 233 is a cavity wall of the mounting cavity 231 for bearing the water tank 210.

[0058] The pushing assembly 120 is capable of moving to the unlocking position in the first direction F under the driving of the external operation end. Therefore, the operation end, such as a hand, of an operator can operate the pushing assembly 120. Since the pushing assembly 120 moves to the unlocking position in the first direction F, which is a direction away from the first cavity wall 233, the unlocking operation of the switch assembly 100 has the same direction and tendency as picking up and moving out the water tank 210 from the mounting cavity 231. Therefore, the pulling-out action of the water tank 210 can be synchronized with the unlocking operation, so that the dismounting process of the water tank 210 is simple and labor-saving.

[0059] Further, the water tank 210 can be movably coupled with the first cavity wall 233, and an included angle between the first direction F and a pulling-out direction of the water tank 210 relative to the first cavity wall 233 can be less than ninety degrees, which means that the first direction F has the same direction and tendency as the pulling-out direction. In addition, the stopper 110 can be arranged on a second cavity wall 232 of the mounting cavity 231.

[0060] In the embodiments of the present application, in combination with Figure 3 , Figure 5 and Figure 7 , the water tank 210 is configured with a containing cavity 211. The pushing assembly 120 comprises a pushing body 121, an extension arm 122 arranged on the pushing body 121, and a limiting part 123 arranged on the extension arm 122. The pushing body 121 is movably arranged in the containing cavity 211.

[0061] In some embodiments, a wall of the water tank 210 facing the stopper 110 is provided with a first opening 235. Another side of the containing cavity 211 away from the first opening 235 is provided with a stop edge 2151, which can limit the movement of the pushing body 121 in the second direction S.

[0062] Further, the extension arm 122 and the limiting part 123 extend out of the containing cavity 211 from the first opening 235.

[0063] As Figure 5As shown, the stopper 110 is configured as a block protruding from the cavity wall of the mounting cavity 231. When the push assembly 120 is in the locked position, the stopper 110 is arranged on the side of the limiting portion 123 close to the opening. It can be understood that, Figure 5 Only one of the positions of the locked position is shown. As long as the push assembly 120 is not in the unlocked position, it can be in any of the positions of the locked position. Figure 2 As shown, the stopper 110 is arranged on the side of the limiting portion 123 close to the opening under the action of the elastic reset member 220, so that the stopper 110 is arranged on the side of the limiting portion 123 close to the opening.

[0064] In this way, most of the structure of the push assembly 120 is accommodated in the accommodation cavity 211, so that the limiting portion 123 for stopping extends out of the accommodation cavity 211, and most of the structure of the switch assembly 100 is accommodated inside the water tank 210, which is more aesthetic.

[0065] Further, the water tank 210 is configured with the accommodation cavity 211, and the outer wall of the water tank 210 is further provided with the operation opening 212 in communication with the accommodation cavity 211. In this way, the external operation end can enter the accommodation cavity 211 through the operation opening 212 to operate the push assembly 120.

[0066] Further, in combination with Figure 2 , Figure 3 and Figure 7 , the number of stoppers 110, extension arms 122, limiting portions 123 and first openings 235 is two.

[0067] The two extension arms 122 are oppositely arranged, and the two limiting 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 mounting cavity 231. Exemplarily, the mounting cavity 231 can further include a second cavity wall 232 oppositely arranged with the first cavity wall 233. The stopper can be located on the second cavity wall 232.

[0068] In 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 be arranged one by one with the two limiting portions 123.

[0069] When the number of stoppers 110, extension arms 122, limiting portions 123 and first openings 235 is two, the two extension arms 122 can be arranged on the two sides of the push body 121, and the two limiting portions 123 can also be arranged on the two sides of the push body 121. In this way, the push body 121 can be stopped on the two sides at the same time, and the stopping effect is better.

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

[0071] In an example, the number of the first openings 235 can be two.

[0072] In the embodiments of the present application, referring to Figure 2 and Figure 7 , the stopper 110 and the second cavity wall body 2321 have a space therebetween. When the push assembly 120 is in the unlocking position, the position of the limiting portion 123 in the first direction F corresponds to the space, the limiting portion 123 is above the stopper 110 and can move horizontally outward from the space to escape from the stopper 110, thereby releasing the locking with the stopper 110. Referring to Figure 5 , when the push assembly 120 is in 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 out of the mounting cavity 231.

[0073] In this way, when the push assembly 120 is in the unlocking position, the limiting portion 123 can escape from the space when the operator drives the water tank 210 to escape from the mounting cavity 231, and will not affect the escape of the water tank 210. When the push assembly 120 is in the locking position, the limiting portion 123 is blocked by the stopper 110, and the water tank 210 cannot escape from the mounting cavity 231.

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

[0075] Further, referring to Figure 2 and Figure 3 , the switch assembly 100 further comprises an elastic reset member 220, which is arranged between the push assembly 120 and the cavity wall of the accommodating cavity 211 and always applies an elastic force to the push assembly 120 in the second direction. 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 the long-closed state without external force.

[0076] By setting the inclined surface 111 on the surface of the stopper 110, the limiting portion 123 can be guided to move to the locking position. Specifically, when the top of the water tank 210 is pushed into the body 230, the limiting portion 123 of the push assembly 120 contacts the inclined surface 111 on the stopper 110, and under the action of the horizontal pushing force, the limiting portion 123 will move upward along the inclined surface 111, in this process, the elastic return member 220 is gradually compressed, when the limiting portion 123 moves to the top end of the inclined surface 111, further movement will move away from the stopper 110, into the rear side of the stopper 110, at this time, the push assembly 120 moves downward (moves in the second direction S) under the action of the elastic force of the elastic return member 220, until the bottom of the push body 121 abuts to the bottom of the accommodating cavity 211. At this time, the limiting portion 123 is in stop cooperation with the stopper 110, and the stopper 110 is blocked on the outside of the limiting portion 123.

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

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

[0079] Further, referring to Figure 6 and Figure 8 , the water tank 210 comprises a water tank body 214, a water tank cover 215 and a baffle 216.

[0080] The water tank cover 215 is provided on the top of the water tank body 214, and the water tank cover 215 is internally structured with a mounting groove 2150.

[0081] The baffle 216 is provided on the top of the water tank body 214 and is provided on one side of the slot of the mounting groove 2150, and the baffle 216 and the water tank cover 215 jointly enclose the accommodating cavity 211, and the operation port 212 is provided on the baffle 216.

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

[0083] Further, in combination with Figure 3 and Figure 8The pressing body 121 is provided with a pressing groove 125. The opening of the pressing groove 125 is arranged correspondingly to the operating port 212. A person's hand can enter the receiving cavity 211 through the operating port 212 and the opening of the pressing groove 125.

[0084] The wall portion of the push groove 125 near the extension arm 122 is formed into a push surface 1250 for unlocking operation by an external operating end. Figure 8 In the example, the pressing surface 1250 is constructed as a plane.

[0085] Or refer to Figure 9 In another possible implementation, the pressing surface 1250 is provided with a recessed portion 1251 recessed toward the stop member 110.

[0086] With the recessed portion 1251 provided, it is convenient for a person's fingers to be inserted into the recessed portion 1251 to operate the pressing surface 1250. Compared with the flat pressing surface 1250, when the fingers are placed in the recessed portion 1251, it is not easy for them to slip relative to the pressing surface 1250, which makes the pressing operation more reliable.

[0087] Furthermore, combined Figure 2 and Figure 8 The mounting groove 2150 has a notch on the wall near the water tank body 214. A retaining edge 2151 is also defined on this wall. That is, the bottom of the water tank cover 215 is designed with a hollow structure. This design saves raw materials, reduces weight, and facilitates injection molding of the water tank cover 215. At this time, the mounting groove 2150 communicates with the interior of the water tank body 214 through this notch.

[0088] Furthermore, the baffle 216 has a protruding rib 2160 on its inner surface facing the water tank cover 215. The protruding rib 2160 abuts against the end of the water tank cover 215. With this arrangement, the movement of the water tank cover 215 along the first direction F is limited by the protruding rib 2160.

[0089] In this embodiment of the application, combined with Figure 1 , Figure 7 When the pushing assembly 120 is in the unlocked position, the stop 110 disengages from the pushing assembly 120, allowing the water tank 210 to enter and exit the mounting cavity 231 from the side of the body 230 through the opening of the mounting cavity 231. Figure 1 , Figure 5 When the push assembly 120 is in the locked position, a portion of the push assembly 120 extends out of the receiving cavity 211 and engages with the stop member 110. At this time, the stop member 110 blocks the outside of the push assembly 120, preventing the water tank 210 from disengaging from the mounting cavity 231.

[0090] Continue to refer to Figure 1The water tank 210 can be plugged into and unplugged with the first cavity wall 233. Specifically, the bottom of the water tank 210 has a water tank inlet 213, and the first cavity wall 233 of the body 230 has a body inlet 234. The water tank inlet 213 and the body inlet 234 can be plugged into and unplugged via a one-way valve. Since the direction in which the water tank 210 is pulled out relative to the first cavity wall 233 is the same as the direction of the unlocking operation performed by the operator, in... Figure 1 In the example, the pulling direction can be upward, and the first direction F is also upward. Therefore, during the process of lifting the water tank 210, the valve body of the one-way valve will close in a short time. This can reduce the leakage phenomenon when the water tank inlet 213 and the body inlet 234 are separated from each other to a certain extent, and improve the user experience.

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

[0092] The following is combined Figures 1-8 This paper describes the operation of the switch assembly 100 in the household appliance 200.

[0093] When it is necessary to remove the water tank 210, the pusher body 121 is pushed upwards by hand. During this process, the pusher body 121 overcomes the elastic force of the elastic reset member 220 and moves along the first direction F. When the limiting part 123 on the pusher assembly 120 is higher than the body stop member 110, the limiting part 123 and the stop member 110 are released from the stop engagement. The limiting part 123 can then disengage from the gap between the stop member 110 and the second cavity wall body 2321. At this time, the water tank 210 can be pulled outwards from the mounting 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 machine body 230. Then the top of the water tank 210 is directly pushed horizontally into the installation cavity 231 of the machine body 230 to complete the installation. Specifically, when the top of the water tank 210 is pushed into the machine body 230, the limiting portion 123 of the push assembly 120 contacts the inclined surface 111 on the stop piece 110, and under the action of the horizontal pushing force, the limiting portion 123 will move upward along the inclined surface 111, and in this process, the elastic return piece 220 is gradually compressed. When the limiting portion 123 moves to the top end of the inclined surface 111, it will move away from the stop piece 110 and enter the rear side of the stop piece 110. At this time, the push assembly 120 moves downward (moves in the second direction S) under the action of the elastic force of the elastic return piece 220, until the bottom of the push body 121 abuts against the stop edge 2151. At this time, the limiting portion 123 is in stop cooperation with the stop piece 110, and the stop piece 110 is blocked outside the limiting portion 123. At this time, the water tank 210 is positioned in the installation cavity 231, realizing the function of locking the water tank 210.
