Detailed Description

The invention provides a refrigerator display device. The refrigerator display device is used for displaying the functions and effects of the dry-wet separate storage refrigerator to a user, and enables the user to experience the difference between the moisturizing chamber 12 and the drying chamber 11. The refrigerator display device can be displayed in home appliance exhibition or sales places (such as home appliance markets, home appliance exhibitions and the like), and before the refrigerator is purchased, a user can use the display device to experience the use effect of the refrigerator in advance. In this embodiment, the refrigerator showcase includes: the humidity control device comprises an outer box body 70, an inner box body 10, an air outlet device 30, a first exhaust device 41, a second exhaust device 42, a first atomization device 21, a second atomization device 22, a humidity control device 50, a first humidity detection device, a second humidity detection device, a first display device 61, a second display device 62, a first human body detection device and a second human body detection device.

As shown in fig. 1 and 2, a drying compartment 11 and a moisturizing compartment 12 are formed adjacent to each other inside the inner case 10. The drying compartment 11 and the moisturizing compartment 12 are independent spaces. The drying chamber 11 is used for simulating a drying storage area of an actual refrigerator product, the drying storage area is used for storing low-humidity foods such as dried fruits and medicinal materials, and the area in the actual refrigerator mainly has a dehumidification function. The moisturizing compartment 12 is used for simulating a moisturizing storage area of an actual refrigerator product, the moisturizing storage area is used for storing high-humidity food such as fruits and vegetables, the area mainly has the functions of dehumidification, moisturizing and the like, and the humidity value of the moisturizing storage area is far larger than that of a dry storage area. The user can put hands into the drying chamber 11 and the moisturizing chamber 12 respectively to feel the different humidity environments of the two different areas in the refrigerator, and the working process and the realized functions of the two areas.

The first atomizing device 21 is disposed inside the drying compartment 11 and is used for supplying gaseous water mist to the drying compartment 11. The second atomizing device 22 is disposed inside the moisturizing compartment 12 and is used for providing gaseous water mist to the moisturizing compartment 12. The two atomization devices respectively provide water mist for the two compartments to simulate moist cold air in the air-cooled refrigerator. In the present embodiment, the first atomization device 21 and the second atomization device 22 are both disposed at the bottom of the inner box 10 of the corresponding compartment.

The air outlet device 30 is disposed on the inner box 10 and used for inputting air flow into the drying chamber 11. The first exhaust device 41 is provided on the inner case 10 to exhaust air inside the drying compartment 11. And a second air exhaust device 42 provided in the inner casing 10 for exhausting air inside the moisture retention chamber 12.

The air outlet device 30 and the first exhaust device 41 are both disposed on a side wall of the inner box 10 away from the moisturizing compartment 12. As shown in fig. 1 and 2, the air outlet device 30 is disposed at an upper portion of the sidewall, and the first exhaust device 41 is disposed at a lower portion of the sidewall. In order to save the internal space of the compartment, it is preferable that the air outlet device 30 and the first air exhaust device 41 are disposed outside the drying compartment 11, and two air ports are opened at corresponding positions of the inner box 10, so that the air outlet device 30 and the first air exhaust device 41 communicate with the drying compartment 11. In the present embodiment, both the air outlet device 30 and the air exhaust device may be axial fans.

The air outlet device 30 and the first exhaust device 41 are used for respectively simulating an air outlet and an air return inlet of the air-cooled refrigerator. When the air outlet device 30 and the exhaust device are simultaneously opened, the air flow enters the upper part of the drying chamber 11 from the air outlet device 30, and after flowing to the lower part of the drying chamber 11, the air flow is exhausted by the first exhaust device 41. The air can form an air flow circulation (an air flow circulation shown by a dotted line in fig. 2) inside the drying compartment 11 to simulate an internal air flow circulation inside the air-cooled refrigerator.

The inner wall of drying compartment 11 adjacent to moisturizing compartment 12 is an arc-shaped surface with a middle portion protruding toward moisturizing compartment 12. That is, the section of the inner space of the drying compartment 11 parallel to the front side of the inner case 10 is semicircular near the moisture retention compartment 12. After entering the drying chamber 11 from the air outlet device 30, the air flow is guided by the arc-shaped surface to reach the bottom of the drying chamber 11. Compared with a vertical plane, the arc-shaped surface can enable airflow circulation to be smoother, and simulation reality degree of the air-cooled refrigerator is improved.

Since the airflow inside the drying compartment 11 continuously circulates, the humidity inside the drying compartment 11 is low. The relative humidity of the moisturizing compartment 12 is maintained between 40% and 45% by adjusting the steam output of the first atomization device 21. The humidity range is favorable for preservation of dry food (dry fruit, medicinal materials, etc.).

The humidity control device 50 is disposed in the humidity-maintaining chamber 12 for adjusting the humidity of the air in the humidity-maintaining space 121. In this embodiment, the humidity control device 50 is in a flat plate shape and horizontally disposed in the humidity-maintaining compartment 12, and the humidity control device 50 and the inner box 10 located therebelow together define a humidity-maintaining space 121, which is equivalent to a humidity-maintaining storage area of an actual refrigerator product. The moisturizing space 121 is a nearly closed space, and the humidity in the moisturizing space 121 is adjusted by the humidity control device 50, so that the space can achieve a moisturizing effect.

The humidity control device 50 has a three-layer structure, specifically including: a partition 51, a blower 52, and an HCS membrane 53. The partition 51 has an opening, and an electric shutter is disposed at the opening for controllably opening and closing the opening. The blower 52 is provided on an upper layer of the partition 51 to discharge moisture inside the moisturizing space 121. The HCS film 53 is disposed on an upper layer of the blower 52, and controls humidity in a space below the humidity control device 50 to be maintained within a preset humidity range.

In the present embodiment, the fans 52 are micro axial fans 52, and the number of the micro axial fans 52 is 3, and the micro axial fans are arranged in the length direction of the humidity control device 50. The micro axial fan 52 delivers moisture from the area below the moisture control device 50 to the headspace. The second air exhaust 42 further exhausts moisture from the space above the moisture control device 50 out of the humidity-maintaining compartment 12 to simulate the dehumidifying function of the humidity-maintaining compartment 12.

The HCS membrane 53, also called an ecological plant membrane, has a surface having a plurality of minute pores allowing moisture in the air to pass therethrough. The ecological plant film can automatically sense the current humidity of the moisturizing space 121, when the moisturizing space 121 is in a low-humidity state, the pore diameters of the micropores are reduced to inhibit moisture permeation, the pore diameters are expanded to accelerate moisture permeation when the moisturizing space 121 is in a high-humidity state, and the humidity of the moisturizing space 121 is always controlled to be about 90% of that of high-moisture vegetables and fruits.

In this embodiment, the refrigerator display apparatus further includes: a first humidity detection means, a first display means 61, a second humidity detection means, and a second display means 62. The first humidity detection device is arranged inside the drying chamber 11 and used for monitoring the humidity value inside the drying chamber 11 in real time. The first display device 61 is electrically connected to the first humidity detection device and configured to display a humidity value inside the drying chamber 11. The second humidity detection device is disposed inside the moisturizing space 121 and is configured to monitor a humidity value inside the moisturizing space 121 in real time. The second display device 62 is electrically connected to the second humidity detecting device and configured to display the humidity value inside the moisturizing space 121. In this embodiment, the first humidity detection device and the second humidity detection device are both humidity sensors. The first display device 61 and the second display device 62 are respectively disposed at the corners of the bottoms of the drying chamber 11 and the moisturizing chamber 12, and preferably, the first display device 61 and the second display device 62 are both LED display screens.

The front surface of the inner box 10 is further opened with two openable windows, and the two windows are respectively communicated with the drying chamber 11 and the moisturizing chamber 12 (in fig. 1 and 2, for convenience of showing the two chambers, the front surface of the inner box 10 is not shown). In order to facilitate the user experience, two windows respectively communicated with the drying chamber 11 and the moisturizing chamber 12 are formed in the front surface of the inner box body 10, and a user can stretch a hand into the drying chamber 11 or the moisturizing chamber 12 to experience a drying storage area and a moisturizing storage area of the refrigerator. The size of the window can be set according to the size of the arm of the human body. In this embodiment, both windows are provided with electrically controlled doors for opening/closing the windows.

The above refrigerator display device further comprises: a first human body detection device and a second human body detection device. And the first human body detection device is arranged inside the drying chamber 11 and used for detecting whether the body part of the user enters the drying chamber 11. The second human body detecting device is disposed inside the moisturizing compartment 12 and is used for detecting whether a body part of a user enters the moisturizing compartment 12. In the present embodiment, the first and second human body detection devices may be infrared sensors respectively disposed in the drying compartment 11 and the moisturizing compartment 12. When the infrared sensor senses that the user's hand enters the inside of the drying compartment 11 or the moisturizing compartment 12, the drying compartment 11 or the moisturizing compartment 12 starts the simulation work. During the time when the infrared sensor does not sense the hand of the user entering, some devices (the atomizing device, the air outlet device 30, the air exhausting device, etc.) in the drying chamber 11 or the moisturizing chamber 12 may be in a closed state, and the first display device 61 and the second display device 62 may display a preset value.

The above refrigerator display device further comprises: an outer case 70. The outer case 70 is disposed outside the inner case 10, and integrally packages the components inside the refrigerator display apparatus.

The invention provides a control method of a refrigerator display device. Fig. 4 is a schematic view of a control method of a refrigerator showcase according to an embodiment of the present invention. The method is used for controlling the refrigerator display device to simulate the environment and the dehumidification function of a dry storage area in an actual refrigerator. The method generally comprises the steps of:

step S402 detects that the user starts the experience process of the drying chamber 11. In this embodiment, whether the user starts to experience can be sensed by the first human body detecting device to determine whether the user's limb enters the drying chamber 11.

In step S404, the humidity inside the drying chamber 11 is continuously detected to monitor the humidity change inside the drying chamber 11.

Step S406, the air outlet device 30 and the first exhaust device 41 are turned on. After the air outlet device 30 and the first exhaust device 41 are opened, an airflow circulation is formed inside the drying chamber 11, and the airflow circulation can reduce the saturated vapor pressure of air, thereby reducing the humidity inside the drying chamber 11.

In step S408, it is determined whether the humidity in the drying chamber 11 has decreased to the first humidity threshold. In this embodiment, the first humidity threshold is a normal humidity value in the dry storage area of the actual product of the refrigerator, and preferably, may be set to 45%.

In step S410, if the determination result in step S408 is yes, the air outlet device 30 and the first exhaust device 41 are closed, and the experience process is ended.

In the method of the embodiment, the air outlet device 30 and the first exhaust device 41 are used to simulate the air outlet and the air return inlet of the air-cooled refrigerator, and air circulation is formed in the drying chamber 11, so as to realize the dehumidification function of the drying chamber 11. In the experience process, a user can sense the change of the humidity in the drying chamber 11 from high to low, so that the dehumidification function of the drying storage area of the actual refrigerator is known.

Fig. 5 is a flowchart of a control method of a refrigerator showcase according to an embodiment of the present invention. The method sequentially executes the following steps:

in step S502, the first display device 61 displays the humidity 45%. Upon detecting that no user experiences the drying compartment 11, the first display device 61 always displays a relative humidity of 45% regardless of the actual humidity in the compartment. This arrangement can reduce the workload of the display device on the one hand and prompt the user that the normal operating humidity of the drying chamber 11 is 45% on the other hand.

In step S504, the first atomizer 21 is turned on. Before the user experiences, a proper humidity environment needs to be created in advance so as to facilitate the experience of the subsequent user. The first atomization means 21 starts atomization, increasing the humidity value of the drying compartment 11.

In step S506, the humidity in the drying chamber 11 is continuously detected.

In step S508, it is determined whether the humidity of the drying chamber 11 has increased to 60%. Due to the continuous operation of the first atomization means 21, the humidity in the drying compartment 11 gradually rises.

Step S510, the air outlet device 30 and the first exhaust device 41 are opened, and an airflow circulation is formed inside the drying chamber 11, so that the internal humidity thereof is gradually decreased.

In step S512, it is determined whether the humidity of the drying chamber 11 has decreased to 55%.

Step S514, the air outlet device 30 and the first exhaust device 41 are closed. After the air outlet device 30 and the first exhaust device 41 are closed, the humidity value will rise again.

In step S516, it is detected that the user' S limb enters the drying compartment 11. In this embodiment, whether the user starts to experience can be sensed by the first human body detecting device to determine whether the user's limb enters the drying chamber 11. If the determination result in step S516 is negative, the air outlet device 30 and the first air outlet device 41 are continuously opened and closed in a circulating manner, so that the humidity in the drying chamber 11 is maintained at 55% to 60%.

In step S518, if the determination result in step S516 is yes, the first display device 61 displays the actual humidity of the drying chamber 11. After determining that the user starts to experience, the first display device 61 normally displays the actual humidity of the drying chamber 11, so that the user can feel the humidity change in the drying chamber 11 more intuitively.

In step S520, the humidity inside the drying chamber 11 is continuously detected to monitor the humidity change inside the drying chamber 11.

In step S522, the air outlet device 30 and the first exhaust device 41 are turned on. After the air outlet device 30 and the first exhaust device 41 are opened, an airflow circulation is formed inside the drying chamber 11, and the airflow circulation can reduce the saturated vapor pressure of air, thereby reducing the humidity inside the drying chamber 11.

In step S524, it is determined whether the humidity in the drying chamber 11 has decreased to the first humidity threshold. In this embodiment, the first humidity threshold is a normal humidity value in the dry storage area of the actual product of the refrigerator, and preferably, may be set to 45%.

In step S526, if the determination result in step S524 is yes, the air outlet device 30 and the first exhaust device 41 are closed, and the experience process is ended. During the experience process, the user can perceive the change of the humidity in the drying chamber 11 from high to low, namely, the humidity is reduced to 45% from more than 55%.

The invention also provides a control method of the refrigerator display device. Fig. 6 is a schematic view of a control method of a refrigerator showcase according to another embodiment of the present invention. The method is used for controlling the refrigerator display device to simulate the environment of a moisturizing storage area in an actual refrigerator and the dehumidifying and moisturizing functions. The method generally comprises the steps of:

step S602 detects that the user starts the experience process of the moisturizing compartment 12. In this embodiment, whether the user starts to experience can be determined by sensing whether the user's limb enters the moisturizing compartment 12 through the second human body detection device.

In step S604, the humidity in the moisturizing space 121 is continuously detected to monitor the humidity change of the moisturizing space 121.

In step S606, the blower 52 and the second exhaust device 42 are turned on. After the fan 52 and the second air exhausting device 42 of the humidity control device 50 are turned on, the moisture in the moisturizing space 121 is exhausted out of the moisturizing compartment 12, thereby reducing the humidity in the moisturizing space 121.

In step S608, it is determined whether the humidity of the moisturizing space 121 is decreased to the fourth humidity threshold. In this embodiment, the fourth humidity threshold is a normal humidity value in the moisture storage area of the actual product of the refrigerator, and preferably, may be set to 90%.

In step S610, if the determination result in step S608 is yes, the blower 52 and the second exhaust device 42 are turned off.

Step S612, after waiting for a preset time, ending the experience process. In this embodiment, the preset time may be 1-2 min. Within a preset time, due to the HCS film 53, the humidity of the moisture-preserving space 121 does not decrease after decreasing to 90%, that is, the humidity of the moisture-preserving space 121 can always maintain an air environment with a relative humidity of 90% suitable for fruit and vegetable preservation.

The method of the embodiment discharges the moisture in the moisturizing space 121 by controlling the fan 52 and the second air discharging device 42 of the humidity control device 50, so as to realize the dehumidifying function of the moisturizing compartment 12. In addition, the moisturizing space 121 can maintain the humidity at 90% due to the HCS film. In the experience process, a user can sense the change of the humidity in the moisturizing space 121 from high to low, and the humidity is continuously kept at the fourth humidity threshold value, so that the dehumidifying function and the moisturizing function of the actual moisturizing storage area of the refrigerator are known.

Fig. 7 is a flowchart of a control method of a refrigerator showcase according to another embodiment of the present invention. The method sequentially executes the following steps:

in step S702, the second display device 62 displays the humidity 90%. Upon detecting that no user experiences the moisturizing compartment 12, the second display device 62 always displays a relative humidity of 90% regardless of the actual humidity within the moisturizing space 121. This arrangement can reduce the workload of the display device on the one hand and prompt the user that the normal operating humidity of the moisturizing space 121 is 90% on the other hand.

In step S704, the second atomizer 22 is turned on. Before the user experiences, a proper humidity environment needs to be created in advance so as to facilitate the experience of the subsequent user. The second atomization device 22 starts atomization, and increases the humidity value of the moisturizing space 121.

In step S706, the humidity in the moisturizing space 121 is continuously detected.

In step S708, it is determined whether the humidity of the moisturizing space 121 is increased to 85%. Due to the continuous operation of the second atomization device 22, the humidity in the moisturizing space 121 gradually rises.

In step S710, the blower 52 and the second exhaust device 42 are turned on, and the humidity in the moisturizing space 121 is gradually decreased.

In step S712, it is determined whether the humidity of the moisturizing space 121 is reduced to 80%.

In step S714, the fan 52 and the second exhaust 42 are turned off. After the fan 52 and the second exhaust 42 are turned off, the humidity level will rise again.

In step S716, it is detected that the user' S limb enters the moisturizing compartment 12. In this embodiment, whether the user starts to experience can be determined by sensing whether the user's limb enters the moisturizing compartment 12 through the second human body detection device. If the determination result in the step S516 is negative, the circulation of the opening and closing fan 52 and the second exhaust device 42 is continued so that the humidity in the moisturizing space 121 is maintained at 80% to 85%.

In step S718, if the determination result in step S716 is yes, the second display device 62 displays the actual humidity of the moisture retention space 121. After determining that the user starts to experience, the second display device 62 normally displays the actual humidity of the moisturizing space 121, so that the user can feel the humidity change in the moisturizing space 121 more intuitively.

In step S720, the humidity in the moisturizing space 121 is continuously detected to monitor the humidity change.

In step S722, the second atomization device 22 is turned on, so that the humidity in the moisturizing space 121 is increased to 95%. To demonstrate the dehumidification function of the moisture retention compartment 12, the humidity in the moisture retention space 121 was first increased to 90% or more.

In step S724, the blower 52 and the second exhaust device 42 are turned on. After the blower 52 and the second exhaust device 42 are turned on, the moisture in the moisturizing chamber 12 is exhausted, and the humidity of the moisturizing space 121 is lowered.
