Description

Technical Field

[0001] This utility model relates to the field of refrigerator technology, specifically to an air intake structure and a refrigerator. Background Technology

[0002] The mainstream preservation functions of existing refrigerators are mainly divided into two categories: one is passive humidity control preservation, which mainly uses humidity control films, oxygen control films, etc. to regulate the humidity and oxygen concentration inside the compartment, slowing down the respiration of fruits and vegetables; the other is active humidity control preservation, which is mainly achieved by adding a separate water source and introducing fresh air from outside the refrigerator to achieve waterless humidity control. Adding a separate water source will take up refrigerator volume, and the fresh air introduced by the waterless fresh air humidity control technology cannot be regulated. When the refrigerator is in a high humidity and high heat environment, the introduced fresh air carries a lot of moisture and heat. After encountering the cold air in the fruit and vegetable drawer, a large amount of condensation will form in a short time and accumulate in the fruit and vegetable drawer and drawer frame. Electric heating methods cannot remove the condensation in a short time and will cause the temperature inside the fruit and vegetable drawer to rise locally, affecting the refrigerator's cooling and food preservation. Furthermore, soaking fruits and vegetables in water for a long time will also accelerate the spoilage of the food.

[0003] Therefore, existing technologies need further development. Utility Model Content

[0049] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0050] See Figures 1 to 9 According to an embodiment of the present invention, an air intake structure is provided, comprising: an air intake component 1 having an air intake duct for introducing fresh air from the outside into a target space; an adjustment component 2 for introducing adjustment air into the air intake duct to reduce the temperature and humidity within the air intake duct; and a control module for controlling the airflow of the adjustment air into the air intake duct based on the temperature and humidity within the target space.

[0051] With the above settings, when fresh air is introduced into the target space, conditioned air is mixed in. The airflow of the conditioned air is adjusted according to the temperature and humidity in the target space, thereby regulating the temperature and humidity of the fresh air. This ensures that the humidity and temperature of the air entering the target space are appropriate, thus guaranteeing the preservation needs of the target space. This effectively solves the technical problem of the fresh air introduced into the refrigerator carrying a large amount of moisture and heat. At the same time, by reducing the condensation in the fruit and vegetable compartment, the operating frequency of the electric heating wire is indirectly reduced, preventing the temperature in the fruit and vegetable compartment from rising due to the operation of the electric heating wire, which would cause cold air loss and achieve the purpose of energy saving in the refrigerator.

[0052] See Figure 6 , Figure 7 In the air intake structure of this embodiment, the air intake structure includes a compartment component 3, and the target space is located inside the compartment component 3; the compartment component 3 is provided with an air inlet, and the air intake assembly 1 is installed at the air inlet. In this way, the air intake assembly 1 can be placed outside the target space, thereby saving the internal space of the target space and allowing more food to be stored.

[0053] See Figures 1 to 5 In the air intake structure of this embodiment, the air intake assembly 1 includes: an air intake housing 12 connected to the compartment component 3; an air intake duct located inside the air intake housing 12; and a fan component 13 disposed within the air intake duct to drive airflow. Thus, by providing the fan component 13, fresh air from the outside is driven into the target space, and simultaneously, the regulating air is mixed with the fresh air, improving regulation efficiency.

[0054] In the air intake structure of this embodiment, see Figures 1 to 5 The air intake assembly 1 includes: an activated carbon box 14 disposed in the air intake duct; the activated carbon box 14 disposed in the target space; and an air intake hole 141 for airflow to pass through the activated carbon box 14.

[0055] Specifically, activated carbon can purify fresh air, and the air inlet 141 on the activated carbon box 14 can adjust the airflow of fresh air, making the fresh air more uniform.

[0056] In some embodiments, there are multiple air inlets 141, and the multiple air inlets 141 are arranged at intervals.

[0057] See Figures 1 to 5 In the air intake structure of this embodiment, the air intake pipe 15 is located on the side of the fan component 13 away from the target space. The air intake pipe 15 is connected to the air intake housing 12 and extends in a direction away from the target space. A ventilation cover 16 for opening or closing the air intake duct is provided on the air intake pipe 15. In this way, when not in use, the ventilation cover 16 can be closed to keep the interior of the structure clean.

[0058] See Figures 1 to 5 In the air intake structure of this embodiment, the heating element 17 is sleeved on the air intake housing 12. Thus, when the airflow cannot meet the demand, the heating element 17 is activated to reduce humidity. The heating element 17, sleeved on the air intake housing 12, increases heating efficiency. It also reduces the operating frequency of the heating wire in the fruit and vegetable compartment, preventing excessive energy consumption due to localized temperature increases within the compartment.

[0059] See Figures 1 to 5In the air intake structure of this embodiment, the adjustment component 2 includes: an adjustment air vent 21, which is connected to the air intake duct; and a baffle plate 22, which is movably arranged to adjust the air volume entering the adjustment air vent 21 by blocking the adjustment air at the adjustment air vent 21.

[0060] By using the above configuration, the baffle 22 is used to block the regulated air entering the regulated air inlet 21, thereby regulating the temperature and humidity of the fresh air. The structure is simple and the cost is low.

[0061] In the air intake structure of this embodiment, see Figures 1 to 5 The adjustment component 2 includes: a drive motor 23, which is connected to the wind deflector 22 to drive the wind deflector 22 to rotate; the drive motor 23 is signal-connected to the control module.

[0062] With the above configuration, the drive motor 23 drives the baffle plate 22 to rotate, and the angle of the baffle plate 22 is adjusted to block the regulating wind entering the regulating air vent 21, thereby regulating the temperature and humidity of the fresh air. The structure is simple and the cost is low.

[0063] See Figures 1 to 5 In the air intake structure of this embodiment, the air intake structure further includes: a dehumidification port disposed on the compartment component 3, the dehumidification port being disposed at a distance from the air intake port; a dehumidification damper 31 for opening or closing the dehumidification port is provided at the dehumidification port; the dehumidification damper 31 is signal connected to the control module.

[0064] With the above settings, when there is too much moisture in the target space, the dehumidification damper 31 will be opened to expel the moisture, thereby preventing the food inside from getting damp.

[0065] In the air intake structure of this embodiment, see Figures 1 to 5 The air intake structure further includes: a temperature and humidity sensor 4, which is used to detect the temperature and humidity in the target space; and / or a humidity control membrane 5, which is used to adjust the humidity in the target space; and / or an oxygen control membrane 6, which is used to adjust the oxygen concentration in the target space.

[0066] The refrigerator of this embodiment includes an air intake structure, which is the air intake structure described above.

[0067] By adopting the above settings, the problem of excessive condensation caused by high humidity and high temperature in the fresh air inside the refrigerator compartment is solved, preventing food from rotting due to soaking in water.

[0068] See Figures 1 to 5In the air intake structure of this embodiment, the refrigerator includes a refrigerator compartment spaced apart from the target space, and the adjustment component 2 includes a cold air duct connected to the refrigerator compartment to introduce the regulated air in the refrigerator compartment into the air intake duct.

[0069] By adopting the above settings, a cold air duct is designed, which uses the cold air inside the refrigerator to premix with the fresh air outside, thereby reducing the moisture and heat in the fresh air and achieving the purpose of adjustable fresh air outside.

[0070] The air intake structure of this embodiment is described as follows:

[0071] Example 1:

[0072] The overall structure of the air intake structure in this embodiment consists of a chamber component 3, a humidity control membrane 5, a temperature and humidity sensor 4, an oxygen control membrane 6, an air intake assembly 1, and a dehumidifying damper 31. The air intake assembly 1 primarily introduces fresh air from outside through the air intake duct, where it is adsorbed and impurities are removed by activated carbon in the activated carbon box 14 before being introduced into the chamber component 3 to increase the internal humidity. The temperature and humidity sensor 4 detects whether the internal humidity of the chamber component 3 reaches a preset range and controls the start of the fan component 13 and the operation of the dehumidifying damper 31 via the main control board based on the room's temperature and humidity. The dehumidifying damper 31 regulates the internal humidity of the chamber component 3 by opening and closing. When the internal humidity of the chamber component 3 is too high, the damper opens, and the humid air inside the chamber is discharged to the outside through air convection, preventing condensation from forming due to excessive internal humidity. The humidity control membrane 5 and the oxygen control membrane 6 assist in regulating the internal humidity and oxygen concentration of the chamber component 3.

[0073] Example 2:

[0074] The air intake assembly 1 of this embodiment consists of an activated carbon box 14, a fan component 13, an air intake duct, a heating wire (i.e., a heating component 17), a baffle plate 22, a motor cover, a gear cover, a ventilation cover, an air intake duct, gears, and a drive motor 23. The air intake duct is embedded in the foam layer between the refrigerator liner 7 and the back panel. The ventilation cover is installed on the back panel of the refrigerator. The air intake duct is connected to the compartment component 3. The assembly of the air intake duct, the air intake duct, and the ventilation cover forms a ventilation duct that runs through the refrigerator's foam layer, connecting the refrigerator's humidifying compartment component 3 to the outside. The fan component 13 is installed in the air intake duct, and the drive motor 23 quickly introduces fresh air from outside into the compartment component 3. An activated carbon box 14 is installed at the port of the air intake duct. The micropores on the activated carbon box 14 can change the airflow and wind speed to achieve windless air delivery. A baffle plate 22, gears, and a drive motor 23 are installed on the top of the air intake duct. The gear cover and motor cover are used to fix the gears and motor. The baffle plate 22 is opened or closed by the drive motor 23, so as to achieve the purpose of autonomously controlling the cold air inside the refrigerator to enter the fresh air system duct.

[0075] Example 3:

[0076] In the air intake structure of this embodiment, the user can independently adjust the humidity range of the compartment according to the types of fruits and vegetables stored in the compartment. The temperature and humidity sensor detects whether the humidity of the compartment meets the preset value. If the humidity of the compartment is greater than the preset value, the fan does not start, and the dehumidifying damper 31 on one side of the humidifying compartment is opened, so that the humidity of the compartment is carried out of the compartment through air convection. At the same time, the baffle is fully opened, and dry and cold air also enters the compartment through air convection. After the humidity of the compartment reaches the preset value, the damper and the baffle are closed. If the humidity of the compartment is less than the preset value, the dehumidifying damper is closed, the fan component 13 is started, and fresh air from the outside is introduced to humidify the compartment component 3. The operation process of the fan component 13 is as follows. When the temperature and humidity sensor 4 detects that the temperature and humidity in the compartment are rising too quickly, the main board controls the drive motor 23 to rotate, opens the baffle 22, and introduces the cold air in the cold storage compartment into the fresh air system channel through the fan component 13. The low-temperature dry cold air and the high-humidity and high-heat fresh air are mixed in the fresh air system to reduce the moisture and heat in the fresh air. This prevents the fresh air entering the fruit and vegetable compartment component 3 from forming a large amount of condensation inside the humidification compartment component 3 due to excessive humidity and temperature, which would cause the food to rot due to soaking in water. In addition, excessive condensation would cause the electric heating wire in the compartment to work frequently, affecting the compartment temperature and causing unnecessary loss of cooling capacity.

[0077] The wind deflector 22 can be opened at different angles by driving motor 23. This program sets the wind deflector 22 to have three opening angles: 30 degrees, 60 degrees, and fully open to 90 degrees. The opening angle of the wind deflector 22 is related to the temperature and humidity in the fresh air. When the temperature and humidity sensor 4 detects a rapid increase in temperature and humidity in the room in a short period of time, the wind deflector 22 opens to 90 degrees, and the fan component 13 introduces the maximum amount of cold air to premix with the fresh air. When the temperature and humidity in the room rises relatively quickly in a short period of time, the wind deflector 22 opens to 60 degrees, and the fan component 13 introduces two-thirds of the cold air to premix with the fresh air. When the temperature and humidity in the room rise slowly in a short period of time, the wind deflector 22 opens to 30 degrees, and the fan component 13 introduces one-third of the cold air to premix with the fresh air.

[0078] In summary, the application of this structure can effectively solve the problem of excessive condensation in the fruit and vegetable compartment during the current water-free fresh air humidity control process in refrigerators, which affects food preservation. At the same time, by reducing the amount of condensation in the fruit and vegetable compartment, the working frequency of the electric heating wire is indirectly reduced, preventing the temperature of the fruit and vegetable compartment from rising due to the operation of the electric heating wire, thus causing loss of cold air and achieving the goal of energy saving in the refrigerator.
