Description

A kind of refrigerator

Technical Field

The invention relates to a refrigerator, in particular to a refrigerator with a humidifying function.

Background

According to the cold air circulation mode, the refrigerator is generally divided into an air-cooled refrigerator and a direct-cooled refrigerator, wherein the air-cooled refrigerator forces the air in the refrigerator to flow through an in-refrigerator fan, so that the temperature in the refrigerator is uniform, the cooling speed is high, and the use is convenient.

However, generally, the air-cooled refrigerator has low overall humidity and the fruit and vegetable food materials stored in the refrigerating chamber are severely dried by blowing air through the fan, so that the food materials are shriveled or even rotten to different degrees after being stored for a long time, and the food value of the food materials is greatly reduced. Therefore, various moisture-preserving and humidity-adjusting drawers are developed in the refrigerator industry for solving the problem, but due to the limitation of the size of the drawer, the use requirement of a user for storing a large amount of fruit and vegetable food materials in a conventional refrigerating chamber at one time cannot be met. In order to further meet the storage requirements of users, some refrigerator enterprises develop in-box humidification technologies, such as ultrasonic humidification, defrosting water humidification and ion humidification.

The ultrasonic humidifying technology is that water mist is formed through high-frequency oscillation of the ultrasonic atomizing sheet and is dissipated in air, and space rapid humidification is achieved. Although the technology can rapidly improve the humidity level in the space, the technology also has the defects of condensation caused by overhigh local humidity, poor reliability, easy failure and the like.

The defrosting water humidification is that water defrosted by the evaporator is collected and then is blown back to the refrigerating chamber again through a humidifying material or a fan, but the technology has the problems of poor humidifying effect, sanitation, safety and the like.

In the ion humidification, large water molecule clusters dissociated in the air are decomposed into smaller water molecules and carry ions through high-voltage ionization, and the charged water molecules are more easily absorbed by fruits and vegetables than the large water molecule clusters dissociated, so that the ion humidification is realized. However, this technique also has a problem of insufficient humidification effect.

Based on the problems in the prior art, the invention provides a refrigerator with a humidifying function.

In this embodiment, as shown in fig. 2 and 4, the humidifying device 300 is disposed on the door liner of the left refrigerating chamber door body 200B, the rotating side of the panel portion 317 of the humidifying device 300 is the left side thereof, and the panel portion 317 is opened from right to left, so that after the panel portion 317 is opened, the structural components thereon and the structural components on the main body portion 316 can be displayed in front of the eyes of the user, so as to facilitate corresponding operations.

Fig. 5 is an exploded view of the side of the case panel portion of the humidifier of this embodiment; referring to fig. 5 in conjunction with fig. 4, the outlet 312 is formed on the panel 317 and is formed with a plurality of densely arranged small holes to allow the humidified air flow to be freely diffused as uniformly as possible; the skeleton member 330 may be an integral structure, i.e., a single integral member, which is clamped to the panel portion 317 in a direction perpendicular to the inner side surface of the panel portion 317 or separated from the panel portion 317 by means of a snap connection, or the skeleton member 330 may be provided on the panel portion 317 in a manner drawable in a direction parallel to the inner side surface of the panel portion 317, i.e., assembled to the panel portion 317 or separated from the panel portion 317 by means of a drawable connection; the outline shape and the size of the framework component 330 are consistent with those of the panel part 317, and the framework component and the panel part 317 are mutually attached, so that the framework component and the panel part 317 form an integral structure as compact as possible, the integral stability of the opening side component of the humidifying device 300 is enhanced as a door body component of the whole humidifying device 300, and the panel part 317 effectively shields the relevant structure of the framework component 330, so that the internal structure of the opened panel part 317 is simple and orderly.

The water absorbing component 340 is detachably arranged on one side of the framework component 330 facing the panel part 317, the water supply assembly 350 is detachably arranged on one side of the framework component 330 facing the main body part 316, so that the water absorbing component 340 and the water supply assembly 350 can be replaced or cleaned after the framework component 330 is opened along with the panel part 317, and the water absorbing component 340 faces the panel part 317, so that the humidified airflow humidified by the water absorbing component 340 can be smoothly discharged from the air outlet 312.

For the guiding duct 331 of the frame member 330, which in this embodiment includes the air inlet section 3311 and the air outlet section 3312, the air inlet section 3311 is communicated with the air outlet side of the fan 320, that is, when the panel portion 317 is closed, the air inlet section 3311 is communicated with the air outlet portion 314 of the fan accommodating portion 313, meanwhile, the air inlet section 3311 is communicated with the air outlet section 3312, and the water absorbing member 340 is specifically located in the air outlet section 3312. Specifically, as shown in fig. 5, the air inlet section 3311 is a long and thin pipe, and the air outlet section 3312 has a larger area and is opened due to the placement of the water absorbing member 340, so that the water absorbing member 340 is attached to the air outlet section 3312 as much as possible, thereby increasing the contact probability with the air outlet flow of the fan 320, improving the humidification effect, and being beneficial to the compact structure and the reduced volume of the humidification apparatus 300.

More specifically, the water absorbing component 340 may be made of water absorbing fiber, super water absorbing fiber PSA, or water absorbing cotton, etc., and needs to satisfy both water absorption and air permeability, for example, a plurality of water absorbing fiber sheets are connected to form a grid-shaped water absorbing component 340, and are clamped in the air outlet 3312 by elastic deformation.

In further detail, as shown in fig. 4 and 5, the water supply assembly 350 includes a water storage box 351 and a water storage bottle 352 in the present embodiment, the water storage capacity of the water storage bottle 352 is larger than that of the water storage box 351, and the water amount in the water storage box 351 is supplemented in real time by the water storage bottle 352. Specifically, the water storage box 351 has an upward opening 3511, and the opening 3511 is used for enabling a part of the water absorbing component 340 to be inserted into the water storage box 351 to be in contact with water in the water storage box 351, that is, a part of the water absorbing component 340, that is, the lower part of the water absorbing component is soaked into the water in the water storage box 351 to achieve contact type water absorption, so that as long as water exists in the water storage box 351, water can be supplied to the water absorbing component 340, then the water is gradually diffused to the rest part of the water absorbing component 340 through the diffusion effect of the water absorbing component 340, and the rest part of the water absorbing component 340 is exposed to the outer side of the water storage box 351, so that air outlet flow of the fan 320 is guided through the water absorbing component 340 through the guide air duct 331. Because the water storage box 351 is an open structure, the volume and the volume of the water storage box are not easy to be overlarge, so that water leakage is avoided. Wherein the water storage box 351 is clamped on the framework part 330 or separated from the framework part 330 along the direction vertical to the inner side surface of the panel part 317, thereby realizing the disassembly and assembly of the water storage box 351. Specifically, a water storage box clamping groove is formed in the outer side face of the water storage box 351, a buckle is correspondingly arranged on the framework part 330, and the water storage box 351 is pushed in the direction perpendicular to the inner side face of the panel portion 317 and is clamped on the framework part 330 through the buckling fit between the water storage box clamping groove and the framework part 330.

Of course, for a refrigerator with a small refrigerating space, the requirement for humidification amount is not high, and the water supply assembly 350 may only include the water storage box 351, and the specific structure of the water supply assembly 350 may be determined according to the volume of the refrigerator.

Referring to fig. 7 to 11 in combination with fig. 3 to 5, the water storage bottle 352 has an appearance identical to that of a general water bottle, and includes a bottle cap 3521 and a bottle body 3522, the bottle cap 3521 is mounted on a bottle opening 3527 of the bottle body 3522 in a matching manner, and a sealing is ensured with a matching surface of the bottle opening 3527, unlike the general water storage bottle, a first water outlet 3523 is formed on the bottle cap 3521, the water storage bottle 352 is inserted into the water storage box 351 in an inverted manner through an opening 3511 of the water storage box 351, that is, the end of the bottle cap 3521 faces downward, a positioning portion 3512 is formed in the water storage box 351, the water storage bottle 352 is supported on the positioning portion 3512, and the positioning portion 3512 positions the water storage bottle 352 at a position where the bottle cap 3521 is spaced from the inner. That is, although the water storage bottle 352 is inverted, due to the support and positioning of the positioning portion 3512 on the water storage bottle 352, the bottle cap 3521 does not contact with the inner bottom surface of the water storage box 351, the inner bottom surface of the water storage box 351 does not block the first water outlet 3523 on the bottle cap 3521, when the water storage bottle 352 is positioned in the water storage box 351 by the positioning portion 3512, water in the bottle continuously flows into the water storage box 351 through the first water outlet 3523 under the action of gravity, automatic water adding to the water storage box 351 is realized until the pressure inside and outside the water storage bottle 352 is consistent, the first water outlet 3523 stops water outlet, and when the internal and external pressure difference of the water storage bottle 352 exists along with the operation of the humidifying device 300, the water storage bottle 352 continuously adds water to the water storage box 351 through the first water outlet 3523 until the pressure inside and outside the water storage bottle 352 is. When the water amount in the water storage bottle 352 is close to exhaustion, the water storage bottle 352 is taken down and filled with appropriate amount of water again to be placed in the water storage box 351 again, so that the water is prevented from being frequently added to the water storage box 351 with small capacity, and the use convenience is improved.

In order to facilitate observation of the amount of water in the water supply assembly 350, in the present embodiment, the observation holes 318 and 333 for observing the water level of the water supply assembly 350 are provided on the panel portion 317 and the frame member 330, respectively, as shown in fig. 3 and 10. The water level of the water supply assembly 350 can be observed from the outside without opening the panel part 317 through the observation hole 318 and the observation hole 333 to add water to the water supply assembly 350 in time.

Further, the positioning portion 3512 is configured to suspend the water storage bottle 352 in the water storage box 351, so that the water can be smoothly discharged without blocking the first water outlet 3523 even if the water storage bottle 352 is suspended in the water storage box 351 in an inverted state. The positioning portion 3512 may be a supporting platform formed on the inner wall of the water storage box 351 in a circle or more than a half circle, and the end face of the bottle body where the bottle mouth 3527 of the water storage bottle 352 is located is supported on the supporting platform; alternatively, the body 3522 of the water storage bottle 352 is formed with a supporting flange having a circumference or more than half circumference, which is supported on the edge of the opening 3511 of the water storage case 351; or the water storage box 351 and the water storage bottle 352 are both provided with positioning structures, and the positioning of the water storage bottle 352 is realized by mutual matching, so that the water storage bottle 352 is suspended in the water storage box 351.

As a specific embodiment, as shown in fig. 10 and 11, the positioning portion 3512 of the present embodiment is formed on the water storage box 351, specifically, on the inner wall of the water storage box 351, and includes a first positioning portion 35121 and a second positioning portion 35122, the first positioning portion 35121 contacts the lower portion of the bottle body 3522 of the water storage bottle 352, and the bottle body 3522 is supported on the first positioning portion 35121; the second positioning part 35122 contacts the bottle cap 3521, the bottle cap 3512 is supported on the second positioning part 35122, and the second positioning part 35122 does not shield the first outlet 3523 to supply water into the water storage box 351.

More specifically, as shown in fig. 10, the first positioning portion 35121 is an L-shaped positioning step, and includes a vertical position-limiting portion a and a horizontal support portion B, the position-limiting portion a fits at least a part of the circumferential contour of the lower portion of the bottle body 3522 (i.e., the portion close to the bottle mouth 3527), and the end face of the bottle body 3522 where the bottle mouth 3527 is located (i.e., the end face of the bottle body 3522 facing the bottle cap 3521) is supported on the support portion B, so as to improve the positioning reliability of the bottle body 3522.

Further, the second positioning portion 35122 is an annular protrusion, which axially penetrates through the annular protrusion, and a communication portion 35123, such as a through hole or a through groove, is formed on the annular protrusion to communicate the space inside the annular protrusion with the space outside the annular protrusion, and the communication portion 35123 is close to the inner bottom surface of the water storage box 351, so that the communication portion 35123 ensures that the first water outlet 3523 can communicate with the water storage space of the water storage box 351, so as to supply water into the water storage box 351 through the first water outlet 3523.

As shown in fig. 10, in this embodiment, the second positioning portion 35122 is a C-shaped ring having a gap to form a communication portion 35123; alternatively, the second positioning portion 35122 may be formed by a plurality of positioning rods arranged in the circumferential direction at intervals, and the first outlet 3523 may smoothly supply water into the water storage case 351 through the gap between the positioning rods.

Furthermore, since the water storage bottle 352 is in an inverted state and the bottle cap 3521 is provided with the first water outlet 3523, the water storage bottle 352 is taken down and turned 180 degrees to enable the bottle cap 3521 to face upwards, namely, the water storage bottle is restored to be upright (namely, the bottle cap 3521 faces upwards), then the bottle cap 3521 is taken down to add water or clean the water storage bottle 352, the water storage bottle is turned 180 degrees again after the water is added or cleaned and is placed into the water storage box 351, and water in the bottle leaks out through the first water outlet 3523 in the process of turning over, so that inconvenience is brought to related operations of a user.

To solve the technical problem, as shown in fig. 7 to 11, a bottle cap 3521 of the water storage bottle 352 in this embodiment includes a mounting portion 3524 and a pressing portion 3525, the mounting portion 3524 is cylindrical, that is, has a mounting hole 3526, specifically a circular hole, penetrating along an axial direction thereof, and the mounting portion 3524 is hermetically mounted on a bottle mouth 3527 of the bottle body 3522 through the mounting hole 3526. In the embodiment, the mounting hole 3526 is in threaded fit with the bottle mouth 3527, and the bottle mouth 3527 is sleeved with the sealing ring C to ensure the sealing between the contact surfaces of the mounting hole 3526 and the bottle mouth 3527; it is understood that the first outlet 3523 may be mounted to the bottle opening 3527 by, for example, a snap fit or other means, and the first outlet 3523 may be located on the mounting portion 3524.

The pressing portion 3525 is slidably connected to the mounting portion 3524, and the pressing portion 3525 is provided with a flow restriction portion 3529 for opening or closing the first water outlet 3523 along with the sliding of the pressing portion 3525. Specifically, the pressing portion 3525 can be pressed to slide relative to the mounting portion 3524, when the water storage bottle 352 is placed upside down in the water storage box 351, the pressing portion 3525 is supported on the second positioning portion 35122, so that the pressing portion 3525 is pressed under the action of the gravity of the bottle itself and the water in the bottle to perform an upward sliding motion relative to the mounting portion 3524, and when the pressing portion 3525 is separated from the second positioning portion 35122, the pressing portion 3525 can be slid downward relative to the mounting portion 3524 to be reset (for example, reset under the action of the gravity of the pressing portion 3525 and the water pressure in the bottle); when the pressing portion 3525 slides (in this embodiment, slides upward relative to the mounting portion 3524) to the first state, as shown in fig. 9, the flow limiting portion 3529 opens the first outlet 3523, and at this time, the water in the water storage bottle 352 flows into the water storage box 351 through the first outlet 3523; when the pressing portion 3525 slides (in this embodiment, slides downward relative to the mounting portion 3524) to the second state, the flow restriction portion 3529 closes the first water outlet 3523, and the water bottle 352 stops discharging water.

Then in the process of taking off the water storage bottle 352 from the water storage box 351 and in the process of turning over to be placed rightly after taking off the water storage bottle 352, and in the process of turning over to be placed rightly, as long as the pressing part 3525 is not pressed to slide, the water in the bottle cannot leak out through the first water outlet 3523, and the water in the bottle 352 is effectively prevented from spilling to the user or the refrigerating chamber of the refrigerator in the turning process.

Further, the sliding direction of the pressing portion 3525 is parallel to the axial direction of the mounting portion 3524, and the axial direction of the mounting portion 3524 coincides with the axial direction of the first water outlet hole 3523 and the axial direction of the bottle 3522, so that the sliding is smooth.

More specifically, a stopping portion 3528 is disposed in the mounting hole 3526, a peripheral edge of the stopping portion 3528 is fixedly connected to an inner wall of the mounting hole 3526 in a sealing manner, the stopping portion and the mounting hole 3526 can be formed into an integral injection molding structure, a first water outlet 3523 is formed in the stopping portion 3528 and penetrates through the thickness direction of the stopping portion 3528, as shown in fig. 9, water in the bottle body 3522 can only flow out of the bottle through the first water outlet 3523, and the rest portions of the bottle body 3522 are sealed and watertight.

Furthermore, to ensure the sealing performance of the protruding portion for sealing the first outlet 3523 when the pressing portion 3525 slides to the second state, an elastic sealing member 390, such as a sealing gasket, may be disposed on the protruding portion for sealing the first outlet 3523 when the protruding portion seals the first outlet 3523.

In order to ensure that the water in the water bottle 352 smoothly flows into the water storage box 351 through the first water outlet 3523 when the pressing portion 3525 is pressed and slid to the first state, a water leakage gap should exist between the pressing portion 3525 and the mounting portion 3524, or a through water leakage hole exists on the pressing portion 3525. In this embodiment, as shown in fig. 8 and 9, a circumferential edge of the pressing portion 3525 is attached to the mounting hole 3526, that is, only a press fit gap exists, a through second outlet hole 35210 is formed on the pressing portion 3525, and the second outlet hole 35210 is communicated with the first outlet hole 3523. When the pressing portion 3525 is pressed and slid to the first state, the water in the water bottle 352 sequentially passes through the first water outlet 3523 and the second water outlet 35210 and smoothly flows into the water storage box 351, and the plurality of second water outlets 35210 can be arranged on the pressing portion 3525 and uniformly distributed along the circumference, so that the water can be discharged smoothly and uniformly.

In order to rapidly return the pressing portion 3525 away from the second positioning portion 35122 and further prevent water leakage, as shown in fig. 8, 9 and 11, a return elastic member, such as a return spring 380, is preferably disposed between the pressing portion 3525 and the stopping portion 3528, and when the pressing portion 3525 is pressed to slide to the first state, the return spring 380 is compressed and stored energy, so that the pressing portion 3525 is rapidly returned away from the second positioning portion 35122.

In order to guide the pressing operation of the pressing portion 3525 so as to make the sliding movement smooth and reliable, as shown in fig. 9 and 11, a first cylindrical guide portion 35211 located outside the first water outlet hole 3523 and surrounding the first water outlet hole 3523 is formed on the stopper portion 3528, a second cylindrical guide portion 35212 surrounding the flow limiting portion 3529 is formed on the pressing portion 3525, the second cylindrical guide portion 35212 is in guiding fit with the first cylindrical guide portion 35211, a guide inclined surface can be provided at a fitting portion, the restoring elastic member 380 is sleeved on the second cylindrical guide portion 35212, the pressing portion 3525 can be prevented from radially shaking by guiding fit of the second cylindrical guide portion 35212 and the first cylindrical guide portion 35211, and the second cylindrical guide portion 35212 can be prevented from radially moving by guiding fit of the restoring elastic member 380, so that the pressing reliability of the pressing portion 3525 is further improved.
