Description

Technical Field

[0001] This application relates to the technical field of low-temperature storage devices, and particularly to a refrigerator. Background Art

[0002] A refrigerator is an electrical device that can maintain a constant low temperature and can provide appropriate temperature and humidity conditions for fresh vegetables, fruits, meats and other food ingredients, thereby improving the freshness preservation effect of food.

[0003] The optimal humidity for preserving vegetables and fruits is generally around 90%, but the low-temperature environment inside the refrigerator is likely to cause the humidity to decrease, resulting in water loss of the items and affecting the freshness preservation effect. To make the humidity environment inside the refrigerator more conducive to the freshness preservation of items, a humidifier is generally provided in the refrigerator, and water mist is sprayed into the inner liner of the refrigerator through the humidifier so that the humidity of the inner liner is suitable for the freshness preservation of the items.

[0004] The existing humidifiers for refrigerators generally include a housing and a water storage box. The water storage box is installed on the housing, and the conduction between the water storage box and the housing is generally through a terminal insertion structure, and the insertion plane of the terminal is likely to cause poor contact. Summary of the Utility Model

[0005] In view of the deficiencies of the above-mentioned prior art, the purpose of this application is to provide a refrigerator, aiming to improve the conduction stability between the housing of the humidifier for the refrigerator and the water storage box in the prior art.

[0006] The problems of this application are not limited to the problems mentioned above, and those skilled in the art can clearly understand other problems not mentioned from the following description.

[0007] To achieve the above purpose, this application has adopted the following technical solutions:

[0008] A refrigerator, comprising a cabinet, a cabinet door and a humidifier; the cabinet is formed with a cabinet having an access opening, the cabinet door is connected to the cabinet and can seal the access opening of the cabinet, and the humidifier is configured to spray humidifying liquid into the cabinet; the humidifier comprises a shell and a water storage box, the shell is connected to the cabinet door, and a receiving cavity is formed in the shell; the water storage box is arranged in the receiving cavity; wherein, a first contact piece and a second contact piece are arranged on the water storage box, and a first elastic contact piece and a second elastic contact piece are arranged on the shell, the first elastic contact piece presses on the first contact piece and is electrically connected to the first contact piece to realize the conduction of the humidifier power supply, and the second elastic contact piece presses on the second contact piece and is electrically connected to the second contact piece to realize the conduction of the humidifier control signal. In the above, due to the elasticity of the first elastic contact piece and the second elastic contact piece, the first elastic contact piece can stably abut against the first contact piece, and the second elastic contact piece can stably abut against the second contact piece, thereby improving the stability of the humidifier power supply and control signal conduction.

[0009] In some embodiments of the present application, a limiting rib is provided in the accommodating cavity, the limiting rib is arranged opposite to the side wall of the shell, and a first installation space is formed between the limiting rib and the side wall of the shell, the first elastic contact piece includes a first fixed end and a first free end, the first fixed end is connected to the first installation space, the first free end extends to the side of the limiting rib facing away from the first installation space, the second elastic contact piece includes a second fixed end and a second free end, the second fixed end is connected to the first installation space, and the second free end extends to the side of the limiting rib facing away from the first installation space. The first elastic contact piece and the second elastic contact piece are fixed by one end respectively, and can be limited by the limiting rib, and the rebound effect is good.

[0010] In some embodiments of the present application, the first elastic contact piece is bent, and a first bending portion and a second bending portion are formed between the first fixed end and the first free end. The first bending portion and the second bending portion are bent inward respectively. The first bending portion is disposed near the first free end and abuts against the first contact piece. The second bending portion is disposed near the first fixed end and passes through the limiting rib. The second elastic contact piece is bent, and a third bending portion and a fourth bending portion are formed between the second fixed end and the second free end. The third bending portion and the fourth bending portion are bent inward respectively. The third bending portion is disposed near the second free end and abuts against the second contact piece. The fourth bending portion is disposed near the second fixed end and passes through the limiting rib. The first elastic contact piece and the second elastic contact piece form an open triangular structure, which can form a guiding effect when the water storage box is inserted into or pulled out of the housing, and makes it not easy for the first elastic contact piece and the second elastic contact piece to deform. The arc surface formed by the first bending portion contacts the first contact piece, and the arc surface formed by the third bending portion contacts the second contact piece, which can reduce the friction generated by the movement of the water storage box.

[0011] In some embodiments of the present application, a first avoidance area and a second avoidance area are provided on the side of the limiting rib facing away from the first installation space. The first avoidance area and the second avoidance area are recessed toward the first installation space. The first avoidance area is correspondingly disposed with the first elastic contact piece, and the second avoidance area is correspondingly disposed with the second elastic contact piece. The first avoidance area can yield to the deformation of the first elastic contact piece to ensure that the first elastic contact piece has sufficient deformation amount. The second avoidance area can yield to the deformation of the second elastic contact piece to ensure that the second elastic contact piece has sufficient deformation amount, and can reduce the force required to pull out or insert the water storage box into the housing.

[0012] In some embodiments of the present application, a first clamping portion and a second clamping portion are respectively provided on the side wall of the water storage box. The first clamping portion is disposed opposite to the first elastic contact piece, and the first contact piece is clamped in the first clamping portion. The second clamping portion is disposed opposite to the second elastic portion, and the second contact piece is clamped in the second clamping portion, which is convenient for the installation of the first contact piece and the second contact piece and can prevent the first contact piece and the second contact piece from shifting.

[0013] In some embodiments of the present application, the first clamping portion includes a first card slot, a second card slot, and a first limiting block. The first card slot and the second card slot are arranged in parallel and form an upward notch. One end of the first contact piece passes through the first card slot from the outside of the water storage box and extends into the water storage box, and abuts against the inner side wall of the water storage box. The other end of the first contact piece passes through the second card slot from the outside of the water storage box and extends into the water storage box, and abuts against the inner side wall of the water storage box. The first limiting block is arranged on the outer side wall of the water storage box and abuts against the upper surface of the first contact piece. The second clamping portion includes a third card slot, a fourth card slot, and a second limiting block. The third card slot and the fourth card slot are arranged in parallel and form an upward notch. One end of the second contact piece passes through the third card slot from the outside of the water storage box and extends into the water storage box, and abuts against the inner side wall of the water storage box. The other end of the second contact piece passes through the fourth card slot from the outside of the water storage box and extends into the water storage box, and abuts against the inner side wall of the water storage box. The second limiting block is arranged on the outer side wall of the water storage box and abuts against the upper surface of the second contact piece. Both ends of the first contact piece are respectively clamped in the first card slot and the second card slot, ensuring the connection stability of the first contact piece. The first limiting block can limit the first contact piece in the height direction, preventing the first contact piece from shifting when contacting the first elastic contact piece, thereby ensuring the stability of the electrical conduction of the humidifier. Both ends of the second contact piece are respectively clamped in the third card slot and the fourth card slot, ensuring the connection stability of the second contact piece. The second limiting block can limit the second contact piece in the height direction, preventing the second contact piece from shifting when contacting the second elastic contact piece, thereby ensuring the stability of the signal conduction of the humidifier.

[0014] In some embodiments of the present application, the water storage box can be pulled out of the accommodating cavity in the first direction to be separated from the housing, which is convenient for adding water to the water storage box and is easy to disassemble and assemble.

[0015] The housing includes a frame body and a baffle. The frame body forms an opening facing the inner box. The opening is arranged on the front side of the frame body along the first direction.

The first contact piece and the second contact piece are arranged as flat contact pieces. The length of the first contact piece along the first direction is greater than the length of the second contact piece along the first direction. When the water storage box is inserted into the housing, the conduction between the first contact piece and the first elastic contact piece precedes the conduction between the second contact piece and the second elastic contact piece, and when the water storage box is pulled out of the housing, the disconnection between the second contact piece and the second elastic contact piece precedes the disconnection between the first contact piece and the first elastic contact piece, ensuring that when the water storage box is assembled, the humidifier can first contact and be powered on, and then contact to realize the control function, and when the water storage box is pulled out of the housing along the first direction, the control signal can be disconnected first, and then the power supply can be disconnected, ensuring the safety of electrical appliance use.

[0018] In some embodiments of the present application, the difference in the lengths of the first contact piece and the second contact piece along the first direction is not less than 3 mm. It can ensure that there is a certain time difference between the humidifier being powered on and the control signal being connected, or ensure that there is a certain time difference between the humidifier disconnecting the control signal and disconnecting the power supply, ensuring the safety of electrical appliance use.

[0019] The effects of the present application are not limited to the effects mentioned above. Those skilled in the art can clearly understand other effects not mentioned from the records of the claims. Description of the Drawings

[0079] As Figure 7 and Figure 9 shown, in some embodiments, the first contact piece 321 and the second contact piece 322 are arranged in a staggered manner. When the water storage box 32 is inserted into the housing 31 along the first direction, the conduction of the first contact piece 321 and the first elastic contact piece 312 precedes the conduction of the second contact piece 322 and the second elastic contact piece 313. That is, the first contact piece 321 first contacts the first elastic contact piece 312, and then the second contact piece 322 contacts the second elastic contact piece 313. If the humidifier 3 simultaneously turns on the power supply and the control signal, it may cause current impact, and may also lead to chaos or out-of-control of the electrical functions, affecting the normal operation and performance of the humidifier 3. By adopting the above method of turning on the power supply first, the current impact generated when the humidifier 3 starts can be avoided, and the service life of the humidifier 3 can be extended. In addition, after the humidifier 3 is powered on, it can first perform self-check and initialization to ensure the normal operation of each component and improve the stability and reliability of the humidifier 3.

[0080] In some embodiments, the length of the first contact piece 321 in the first direction is greater than that of the second contact piece 322 in the first direction. When the water storage box 32 is inserted into the housing 31, the first contact piece 321 can first contact and conduct electricity with the first elastic contact piece 312, and then the second contact piece 322 contacts the second elastic contact piece 313 to achieve the control function. When the water storage box 32 is pulled out of the housing 31, the second contact piece 322 first disconnects from the second elastic contact piece 313 to cut off the control signal; then the first contact piece 321 disconnects from the first elastic contact piece 312 to disconnect the power supply of the humidifier 3.

[0081] In some embodiments, the length difference between the first contact piece 321 and the second contact piece 322 in the first direction is not less than 3 mm. The length difference between the first contact piece 321 and the second contact piece 322 in the first direction can be but is not limited to 4 mm, 5 mm, 6 mm. That is, when the water storage box 32 is inserted into the housing 31, after the first contact piece 321 contacts the first elastic contact piece 312, the water storage box 32 needs to move inward at least 3 mm before the second contact piece 322 can contact the second elastic contact piece 313, ensuring a certain time difference between the humidifier 3 being powered on and the control signal being connected. When the water storage box 32 is pulled out of the housing 31, after the second contact piece 322 disconnects from the second elastic contact piece 313, the water storage box 32 needs to move outward at least 3 mm before the first contact piece 321 can disconnect from the first elastic contact piece 312, ensuring a certain time difference between the humidifier 3 disconnecting the control signal and disconnecting the power supply, and ensuring electrical safety.

[0082] As Figure 5 and Figure 8 As shown, in some embodiments of the present application, a limiting rib 314 can be provided in the accommodation cavity 311. The limiting rib 314 is disposed opposite to the side wall of the housing 31. The limiting rib 314 is disposed opposite to the side wall of the frame body 312. The limiting rib 314 is spaced from the side wall of the housing 31. A first installation space 315 is formed between the limiting rib 314 and the side wall of the housing 31. The limiting rib 314 is provided with avoidance grooves. There are at least two avoidance grooves. One of the avoidance grooves is correspondingly disposed with the first elastic contact piece 312. The other avoidance groove is disposed opposite to the second elastic contact piece 313. The first elastic contact piece 312 and the second elastic contact piece 313 respectively pass through the avoidance grooves and extend on both sides of the limiting rib 314. The limiting rib 314 can limit the deformation amount of the first elastic contact piece 312 and the second elastic contact piece 313, ensuring the recovery ability of the first elastic contact piece 312 and the second elastic contact piece 313.

[0083] In some embodiments, the first elastic contact piece 312 may include a first fixed end 3121. The first fixed end 3121 is connected in the first installation space 315. The second elastic contact piece 313 includes a second fixed end 3131. The second fixed end 3131 is connected in the first installation space 315. Positioning posts are provided in the first installation space 315, and the first elastic contact piece 312 and the second elastic contact piece 313 are respectively fixed in the first installation space 315 through the positioning posts. Positioning holes are provided in the first installation space 315. There are multiple positioning holes. A screw hole is provided on the first fixed end 3121 of the first elastic contact piece 312. The first fixed end 3121 can be connected to the positioning hole in the first installation space 315 by a screw. A screw hole is provided on the second fixed end 3131 of the second elastic contact piece 313. The second fixed end 3131 can be connected to the positioning hole in the first installation space 315 by a screw.

[0084] In some embodiments, the first elastic contact piece 312 may include a first free end 3122. The first free end 3122 is arranged on the side of the limiting rib 314 facing away from the first installation space 315, so that the first elastic contact piece 312 has deformability and resilience to ensure that the water storage box 32 can be smoothly pulled out and inserted.

[0085] In some embodiments, the second elastic contact piece 313 may include a second free end 3132. The second free end 3132 is arranged on the side of the limiting rib 314 facing away from the first installation, so that the second elastic contact piece 313 has deformability and resilience to ensure that the water storage box 32 can be smoothly pulled out and inserted.

[0086] Figure 10 For Figure 6 the enlarged view of region E in

[0087] As Figure 8 and Figure 10 shown, in some embodiments of the present application, the first elastic contact piece 312 is bent. A first bending portion 3123 and a second bending portion 3124 are formed between the first fixed end 3121 and the first free end 3122. The first bending portion 3123 and the second bending portion 3124 are respectively bent inward to form an open triangular structure. When the water storage box 32 is inserted into or pulled out of the housing 31, this bending structure can form a guiding effect and make it difficult for the first elastic contact piece 312 to deform. The first free end 3122 does not contact the limiting rib 314, ensuring that the first elastic contact piece 312 can generate a certain amount of deformation. The first bending portion 3123 is arranged close to the first free end 3122, and the first bending portion 3123 abuts against the first contact piece 321. The outer surface of the first bending portion 3123 forms an arc surface, and the arc surface contacts the first contact piece 321, which can reduce the friction generated by the movement of the water storage box 32.

[0088] The second bending portion 3124 can be arranged close to the first fixed end 3121. The second bending portion 3124 is passed through the limiting rib 314. The second bending portion 3124 is located in the avoidance groove of the limiting rib 314, so that the first elastic contact piece 312 has a certain deformation space.

[0089] In some embodiments, the second elastic contact piece 313 is bent. A third bending portion 3133 and a fourth bending portion 3134 are formed between the second fixed end 3131 and the second free end 3132. The third bending portion 3133 and the fourth bending portion 3134 are bent inward respectively to form an open triangular structure. When the water storage box 32 is inserted into or pulled out of the housing 31, this bending structure can form a guiding effect and make it difficult for the second elastic contact piece 313 to deform. The second free end 3132 does not contact the limiting rib 314, ensuring that the second elastic contact piece 313 can generate a certain amount of deformation. The third bending portion 3133 is arranged close to the second free end 3132, and the third bending portion 3133 abuts against the second contact piece 322. An arc surface is formed on the outer surface of the third bending portion 3133, and the arc surface contacts the second contact piece 322, which can reduce the friction generated by the movement of the water storage box 32.

[0090] The fourth bending portion 3134 can be arranged close to the second fixed end 3131. The fourth bending portion 3134 is passed through the limiting rib 314. The fourth bending portion 3134 is located in the avoidance groove of the limiting rib 314, so that the second elastic contact piece 313 has a certain deformation space.

[0092] As Figure 11 And 12 As shown in

[0093] On one side of the limiting rib 314 facing away from the first installation space 315, a second avoidance area 3142 is provided. The second avoidance area 3142 is recessed towards the first installation space 315. The second avoidance area 3142 is correspondingly arranged with the second elastic contact piece 313. The second avoidance area 3142 can make way for the deformation of the second elastic contact piece 313, ensuring that the second elastic contact piece 313 has sufficient deformation, thereby reducing the force required to pull out or insert the water storage box 32 into the housing 31.

[0094] Figure 13 Structural schematic of the water storage box provided by this application Figure 2 。 Figure 14 For Figure 13 Enlarged view of area B.

[0095] As Figure 13 And Figure 14 Shown in, in some embodiments, a first clamping portion 323 is provided on the side wall of the water storage box 32. The first clamping portion 323 is arranged opposite to the first elastic contact piece 312, and the first contact piece 321 is clamped in the first clamping portion 323, facilitating the installation of the first contact piece 321. The first clamping portion 323 can limit the first contact piece 321 to prevent displacement when the first contact piece 321 contacts the first elastic contact piece 312 during the movement of the water storage box 32, ensuring the stability of the power connection of the humidifier 3.

[0096] In some embodiments, the first clamping portion 323 may include a first clamping groove 3231 and a second clamping groove 3232. The first clamping groove 3231 and the second clamping groove 3232 are arranged in parallel and form an upward notch. One end of the first contact piece 321 extends into the water storage box 32 through the first clamping groove 3231 from the outside of the water storage box 32. One end of the first contact piece 321 abuts against the inner side wall of the water storage box 32. The other end of the first contact piece 321 extends into the water storage box 32 through the second clamping groove 3232 from the outside of the water storage box 32. The other end of the first contact piece 321 abuts against the inner side wall of the water storage box 32. Through the first clamping groove 3231 and the second clamping groove 3232, the installation of the first contact piece 321 is facilitated, and the first contact piece 321 can be limited in the horizontal direction.

[0097] In some embodiments, the first clamping portion 323 may include a first limiting block 3233. The first limiting block 3233 is arranged on the outer side wall of the water storage box 32. The first limiting block 3233 abuts against the upper surface of the first contact piece 321. It can be understood that the first contact piece 321 contacts the bottom of the first clamping groove 3231 and the second clamping groove 3232. In this way, the first limiting block 3233 can limit the movement of the first contact piece 321 in the height direction, thereby ensuring that the first contact piece 321 does not shift when contacting the first elastic contact piece 312 during the movement of the water storage box 32, ensuring the stability of the power connection of the humidifier 3.

[0098] In some embodiments, a second clamping portion 324 is provided on the side wall of the water storage box 32. The second clamping portion 324 is disposed opposite to the second elastic contact piece 313. The second contact piece 322 is clamped in the second clamping portion 324, facilitating the installation of the second contact piece 322. The second clamping portion 324 can limit the second contact piece 322 to prevent displacement when the second contact piece 322 contacts the second elastic contact piece 313 when the water storage box 32 moves, ensuring the stability of the connection of the control signal of the humidifier 3.

[0099] In some embodiments, the second clamping portion 324 may include a third clamping groove 3241 and a fourth clamping groove 3242. The third clamping groove 3241 and the fourth clamping groove 3242 are arranged in parallel and have an upward notch formed. One end of the second contact piece 322 extends into the water storage box 32 through the third clamping groove 3241 from the outside of the water storage box 32. One end of the second contact piece 322 abuts against the inner side wall of the water storage box 32. The other end of the second contact piece 322 extends into the water storage box 32 through the fourth clamping groove 3242 from the outside of the water storage box 32. The other end of the second contact piece 322 abuts against the inner side wall of the water storage box 32. Through the third clamping groove 3241 and the fourth clamping groove 3242, it is convenient for the installation of the second contact piece 322 and can limit the second contact piece 322 in the horizontal direction.

[0100] In some embodiments, the second clamping portion 324 may include a second limiting block 3243. The second limiting block 3243 is disposed on the outer side wall of the water storage box 32. The second limiting block 3243 abuts against the upper surface of the second contact piece 322. It can be understood that the second contact piece 322 contacts the bottom of the third clamping groove 3241 and the fourth clamping groove 3242. In this way, the second limiting block 3243 can limit the movement of the second contact piece 322 in the height direction, so as to ensure that when the water storage box 32 moves, the second contact piece 322 will not be displaced when contacting the second elastic contact piece 313, ensuring the stability of the power connection of the humidifier 3.

[0101] In summary, in the present application, the power of the humidifier 3 is conducted by providing the first elastic contact piece 312 on the housing 31 to contact the first contact piece 321 on the water storage box 32; the control signal of the humidifier 3 is conducted by providing the second elastic contact piece 313 on the housing 31 to contact the second contact piece 322 on the water storage box 32, ensuring the contact stability between the first contact piece 321 and the first elastic contact piece 312, and between the second contact piece 322 and the second elastic contact piece 313, and preventing poor contact between the first contact piece 321 and the first elastic contact piece 312, and between the second contact piece 322 and the second elastic contact piece 313.

[0102] The water storage box 32 and the housing 31 are symmetrically arranged along the first direction respectively, so that the opposite sides of the water storage box 32 and the housing 31 have a consistent assembly gap, ensuring the stability of the disassembly and assembly of the water storage box 32 and the housing 31.

[0103] The first contact piece 321 is snap-fitted and installed through the first snap-fitting portion 323, and the second contact piece 322 is snap-fitted and installed through the second snap-fitting portion 324, which can ensure that the first contact piece 321 and the second contact piece 322 will not be displaced, and the assembly performance is good.

[0104] One end of the first elastic contact piece 312 and the second elastic contact piece 313 is fixed respectively. Through the deformation of the single beam arm, the limiting rib 314 limits the amount of deformation to ensure an appropriate elastic recovery ability.

[0105] When the water storage box 32 is inserted, the first contact piece 321 and the first elastic contact piece 312 come into contact and conduct electricity first, and then the second contact piece 322 and the second elastic contact piece 313 come into contact and connect the control signal. When the water storage box 32 is pulled out, the second contact piece 322 and the second elastic contact piece 313 disconnect the power supply first, and then the first contact piece 321 and the first elastic contact piece 312 disconnect the control signal, ensuring the use safety and operation stability of the humidifier 3.

[0106] It can be understood that for those of ordinary skill in the art, equivalent substitutions or changes can be made according to the technical solutions of this application and its application concept, and these equivalent variations or substitutions are all included in the scope defined by the claims of this application.
