Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration equipment, in particular to a refrigerator. Background Art

[0002] When air-cooled refrigerators are currently in operation, the circulating air draws moisture from the refrigerator compartment to the evaporator, where it condenses. The evaporator defrosts periodically, and the defrosted water evaporates in the evaporator dish or is discharged outside the refrigerator. Consequently, the circulating air carries away moisture from the refrigerator compartment, making the environment dry. This can cause food inside the refrigerator to dry out, especially fruits and vegetables.

[0003] To address the above-mentioned problem of drying fruits and vegetables, some air-cooled refrigerators will have a separate closed fruit and vegetable drawer in the refrigerator compartment, and then install a humidity control device in the drawer, allowing the user to adjust the opening and closing of the air vents to adjust the humidity in the drawer.

[0004] The aforementioned humidity control devices and methods offer limited humidification, require additional user intervention, and only work within closed drawers, failing to address the dry conditions within the refrigerator compartment.

[0049] As Figure 1 shown, is a refrigerator of the preferred embodiment of the present application, mainly comprising a cabinet 100, an air duct, an evaporator 300, a water distribution member 400, a water receiving assembly 500, a drain pipe 600, an atomizing humidifying assembly 700 and a control valve 800.

[0050] The box 100 comprises an outer shell and an inner container which is arranged in the outer shell. An upper inner container in the upper part is provided with a duct cover plate 110 which divides the upper inner container into a rear refrigeration air duct 111 and a front refrigeration chamber 112, and the duct cover plate 110 is provided with air outlet holes and air return holes (not shown in the figure) which communicate with the refrigeration chamber 112. A lower inner container in the lower part is provided with a front cover plate 120 which divides the lower inner container into a rear refrigeration air duct 121 and a front refrigeration chamber 122, and the front cover plate 120 is provided with cold air outlets and air return outlets (not shown in the figure) which communicate with the refrigeration chamber 122.

[0052] Referring to Figure 3 , the upper part of the front cover plate 120 is also provided with a cavity 123, and the water distribution member 400 is arranged in the air duct at a position corresponding to the cavity 123. Referring to Figure 5 , the water distribution member 400 is provided with a partition plate 410 which divides the water distribution member 410 into a first water tank 401 close to the refrigeration chamber 122 and a second water tank 402 away from the refrigeration chamber 122, and the partition plate 410 is provided with an overflow port at a predetermined height. In this embodiment, the water distribution member 400 is an open container, the height of the partition plate 410 is less than the height of the container wall, that is, the positions above the partition plate 410 all belong to the overflow port. The first water tank 401 is provided with a water outlet on the front tank wall 403 close to the refrigeration chamber 122, and the water outlet extends outwardly with a water outlet pipe portion 420.

[0053] Referring to Figure 2 , the water pipe 520 of the water receiving assembly 500 is located at the upper part of the first water tank 401, and can be regarded as communicating with the first water tank 401 to first introduce the defrosting water into the first water tank 401 for use by the atomization and humidification assembly 700. When the liquid level of the defrosting water in the first water tank 401 exceeds the partition plate 410, the water above the liquid level will automatically overflow into the second water tank 402, and the flow direction of the defrosting water is shown by arrows in Figure 2 .

[0054] Referring to Figure 1 andFigure 2 One end of the drain pipe 600 is communicated with the second water tank 402, and the other end extends out of the air duct 200 and can be communicated with the evaporation dish assembly arranged in the cabinet 100 or directly extends out of the cabinet 100, so that the unused excess defrosting water overflowing into the second water tank 402 is drained out of the drain pipe 600. See Figure 4 The bottom surface of the second water tank 402 can be arranged to be downwardly inclined, and an inclined pipe joint 430 is arranged at the lowest point, so as to be conveniently communicated with the drain pipe 600.

[0055] See Figure 3 and Figure 4 The atomizing humidifying assembly 700 is arranged in the intermediate cavity 123. The control valve 800 is arranged in the water outlet pipe portion 420 of the first water tank 401, and the atomizing humidifying assembly 700 is communicated with the first water tank 401 through the control valve 800. Preferably, the bottom surface of the first water tank 401 is arranged to be downwardly inclined toward the refrigerating chamber 122, and the position of the water outlet pipe portion 420 is slightly higher than the highest point of the bottom surface of the first water tank 401.

[0056] See Figure 6 -8, the control valve 800 comprises a water guide pipe 810, a spring (a reset member) 820 and a rubber plug 830.

[0057] The water guide pipe 810 is slidably arranged in the water outlet pipe portion 420. The first end of the water guide pipe 810 arranged in the first water tank 401 is provided with a first clamping portion 812, and the side surface of the first end of the water guide pipe 810 is provided with a second clamping portion 831 for forming detachable clamping with the first clamping portion 812. In the embodiment, the first clamping portion 812 is a mushroom-shaped convex column with a large head and a small root, and the second clamping portion 831 is a mushroom-shaped cavity matched with the shape of the first clamping portion 812, and the two form convenient clamping through the deformation of the rubber plug 830. The size of the rubber plug 830 is greater than the inner diameter of the water outlet pipe portion 420, so that the head of the first end of the water guide pipe 810 is larger than the water outlet pipe portion 420 after assembly, the water guide pipe 810 cannot be taken out of the first water tank 401 from the water outlet pipe portion 420, and the rubber plug 830 has a sealing effect, so as to prevent water from leaking out of the water outlet pipe portion 420 when the control valve 800 is in the closed position (as shown in the state). Figure 8 The water guide pipe 810 has a containing cavity 811, and the side wall of the water guide pipe 810 is provided with a water inlet hole 813 communicated with the containing cavity 811 at a predetermined position close to the first end. The second end of the water guide pipe 810 is provided with a water guide opening 814. Furthermore, the second end of the water guide pipe 810 is provided with a turned-up edge portion 815, the spring 820 is sleeved on the water guide pipe 810 and the water outlet pipe portion 420, one end of the spring 820 abuts against the turned-up edge portion 815, and the other end of the spring 820 abuts against the outer surface of the front tank wall 403, and the initial state of the spring 820 is a compressed state. In order to conveniently fix the spring 820, the turned-up edge portion 815 and the front tank wall 403 can be provided with spring mounting grooves 816. SeeFigure 8 D1 is the distance between the water outlet 420 and the flange 815, and D2 is the distance between the water inlet hole 813 and the inner surface of the front groove wall 403. It is required that D1 > D2.

[0058] In other embodiments, the control valve can adopt other forms, such as the valve body structure of the prior art check valve, fluid control valve, etc., as long as it can ensure that the atomizing humidifying assembly 700 can be installed to discharge water and removed without leaking water.

[0059] Referring to Figure 9 -10, the atomizing humidifying assembly 700 comprises a container seat 710, a decorative cover 720, a sealing ring 730, and an ultrasonic atomizing device 740.

[0060] The container seat 710 comprises a lower box body 711 and an upper cover body 712 which are connected to be opened and closed. The lower box body 711 and the upper cover body 712 form a water storage cavity after being closed. The lower box body 711 is provided with a water inlet port 701 which communicates with the water storage cavity at the lower part of the rear side wall of the air duct 200. The upper cover body 712 is provided with a water outlet port 702 at the upper part of the front side wall of the refrigeration chamber 122. The sealing ring 730 is sleeved on the outer wall of the water inlet port 701 or the inner wall of the water guide port 814. Referring to Figure 4 The inner bottom surface of the lower box body 711 is taken as a reference. H1 is the height of the partition plate 410, and H2 is the height of the side wall of the lower box body 711. It is required that H2 > H1. According to the principle of the communicating vessel, it can be ensured that the liquid level in the lower box body 711 is at most H1 and will not overflow. The ultrasonic atomizing device 740 is arranged at the bottom of the lower box body 711 and is electrically connected with an external control element. It is configured to start working when a predetermined amount of water is stored in the lower box body 711. The ultrasonic atomizing device 740 atomizes the defrosting water in the lower box body 711 through high-frequency oscillation, thereby generating fine water mist. The ultrasonic atomizing device 740 uses electronic high-frequency oscillation (the oscillation frequency is 1.7 MHz or 2.4 MHz, which is beyond the range of human hearing. The electronic oscillation is harmless to human body and animals). The ultrasonic atomizing device 740 generates natural and elegant water mist by dispersing the liquid water molecule structure through the high-frequency resonance of the ceramic atomizing sheet without heating or adding any chemical reagent. Compared with the heating atomizing method, the energy is saved by 90%. In addition, a large amount of negative ions are released in the atomizing process. The negative ions have electrostatic reaction with the smoke, dust, etc. floating in the air, so that the smoke, dust, etc. are precipitated. The negative ions can also effectively remove harmful substances such as formaldehyde, carbon monoxide, and bacteria, so that the air is purified and the occurrence of diseases is reduced. After the water is efficiently atomized by the ultrasonic atomizing device 740, the water molecules are dispersed into small particles, have good fluidity, have a wide diffusion range, have low noise during operation, and are energy-saving and stable.

[0061] In actual assembly, the water inlet port 701 of the container seat 710 is assembled with the water guide port 814 of the water guide pipe 810, and the sealing ring 730 is located between the water inlet port 701 and the water guide port 814 to avoid water leakage at the connection. The initial state of the spring 820 is a compressed state, and when the container seat 710 is not assembled with the water guide pipe 810, the elastic force of the spring 820 causes the water guide pipe 810 to be in a first limit position (as shown in Figure 8 FIG. 1), that is, in a position in which water cannot enter the containing cavity 811 from the water inlet hole 813, so that water in the first water tank 401 cannot flow out of the water guide pipe 810. Referring to Figure 4 When the user assembles the water inlet port 701 of the container seat 710 at the water guide port 814 by pressing, the container seat 710 pushes the water guide pipe 810 to retreat to a position in which water can enter the containing cavity 811 from the water inlet hole 813, and then connects the decorative cover 720 with the front cover plate 120, thereby limiting the container seat 710 in the inter-cavity 123 and keeping the container seat 710 in the assembled state with the water guide port 814. The decorative cover 720 is provided with a cover hole 721 corresponding to the water outlet port 702, so that water mist can enter the refrigeration chamber 122 from the water outlet port 702 and the cover hole 721 (the flow direction of defrosting water is shown by arrows in Figure 4 FIG. 2), circulate in the refrigeration chamber 122 along with the air outlet of the refrigeration air duct 121 (the circulation of water mist is shown by dotted arrows in Figure 1 FIG. 3), and improve the dry environment in the refrigeration chamber 122.

[0062] In summary, the refrigerator provided by the present application at least has the following advantages compared with the prior art.

[0063] Beneficial effects:

[0064] First, the atomization humidifying assembly of the present application can be embedded in the air duct, does not occupy the storage volume in the cavity, can humidify the entire cavity along with air circulation, and effectively improves the dry environment in the cavity.

[0065] Second, the present application uses defrosting water in the refrigeration process of the refrigerator, is energy-saving and environmentally friendly.

[0066] Third, the present application uses a quantitative amount of defrosting water by setting a partitioned water distribution member and automatically discharges the excess defrosting water that is not used, and does not need manual water addition during use, which is convenient to use.

[0067] Fourth, the control valve and the atomization humidifying assembly structure designed in the present application can realize automatic atomization humidification, have small noise, are more energy-saving and stable, and are convenient to assemble and maintain.

[0068] The above only describes the preferred embodiments of the present application, and it should be noted that those of ordinary skill in the art can make several improvements and replacements without departing from the technical principles of the present application, and these improvements and replacements should also be considered as the protection scope of the present application.
