Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a freezer. Background Technology

[0002] Currently, the temperature control methods used in the freezer industry are mostly: 1. A single refrigeration system drives a single temperature zone; 2. Multiple refrigeration systems drive multiple temperature zones respectively; 3. A multi-split refrigeration system drives multiple temperature zones through multiple evaporators; etc. All of these solutions involve one refrigeration system driving one temperature zone or one evaporator driving one temperature zone, resulting in relatively high costs. Summary of the Invention

[0003] The purpose of this invention is to provide a refrigerator that is reliable in performance and helps to reduce costs.

[0004] This utility model discloses a freezer, comprising:

[0005] Cabinet;

[0006] The first room is located on the cabinet;

[0007] The second room is located on the cabinet;

[0008] An air supply duct is provided on the cabinet and includes a first air duct and a second air duct that are respectively connected to the first compartment and the second compartment. The first air duct and the second air duct are respectively used to supply cold air to the first compartment and the second compartment.

[0009] A return air duct is provided on the cabinet and communicates with the first compartment and the second compartment, and is used to receive the cold air output from the first compartment and the second compartment;

[0010] A refrigeration device is installed on the cabinet and includes a return air inlet connected to the return air duct and an air outlet connected to the supply air duct. The refrigeration device is configured to receive cold air delivered by the return air duct through the return air inlet, cool the received cold air, and then send it into the supply air duct through the air outlet.

[0011] An air damper device is provided on the air supply duct and is used to adjust the size of the air inlet of the first air duct and the air inlet of the second air duct to control the air volume of the cold air output from the air outlet entering the first air duct and the second air duct respectively.

[0012] The freezer in this embodiment is equipped with a refrigeration unit and a first air duct and a second air duct that supply cold air to the first and second compartments. It also has an air damper device to adjust the size of the air duct inlet of the first and second air ducts. By adjusting the size of the air duct inlet of the first and second air ducts, the air volume of cold air entering the first and second compartments can be controlled. Thus, the temperature of the first and second compartments can be adjusted using a single refrigeration unit, which is reliable and has a lower cost.

[0013] In some embodiments, the device further includes a first temperature detector for detecting the room temperature of the first room, a second temperature detector for detecting the room temperature of the second room, and a controller. The controller is signal-connected to the first temperature detector, the second temperature detector, and the damper device. The controller is configured to control the damper device to adjust the size of the duct inlet of the first duct and the duct inlet of the second duct based on the detection results of the first temperature detector and the second temperature detector.

[0014] In this embodiment, the controller can monitor the room temperatures of the first and second chambers in real time based on the detection results of the first and second temperature detectors. This allows for automatic control of the inlet sizes of the first and second air ducts. For example, when the room temperature detected by the first temperature detector is higher than a set temperature, the controller controls the damper to increase the opening of the inlet of the first air duct, increasing the airflow of cold air into the first chamber, thus lowering the temperature of the first chamber. Conversely, when the room temperature detected by the first temperature detector is lower than the set temperature, the controller controls the damper to decrease the opening of the inlet of the first air duct, reducing the airflow of cold air into the first chamber, thus lowering the airflow of cold air into the first chamber, thus raising the temperature of the first chamber.

[0015] In some embodiments, the second compartment includes a plurality of partition layers arranged vertically from top to bottom, the second air duct extends vertically, and the freezer also includes a plurality of air inlets arranged vertically from top to bottom and corresponding to and communicating with the plurality of partition layers. The air inlets include partition layer air outlets disposed on the duct wall of the second air duct. The freezer also includes a plurality of air guiding structures corresponding to the partition layer air outlets of the plurality of air inlets. The air guiding structures and their corresponding partition layer air outlets are located on the same side of the duct wall of the second air duct, and the air guiding structures are located below their corresponding partition layer air outlets to guide the air transported by the second air duct into their corresponding partition layer air outlets.

[0016] In this embodiment, the second air duct extends vertically. When the second air duct delivers cold air from top to bottom, the flow rate of the cold air entering the corresponding partition layer of the second room through multiple partition layer air outlets on the duct wall will be uneven. An air guide structure is provided below each partition layer air outlet to adjust the amount of cold air entering each partition layer air outlet. Thus, by setting the air guide structure, the air volume delivered by the second air duct to each partition layer air outlet can be made more uniform.

[0017] In some embodiments, the air guiding structure includes an air guide plate with one end connected to the duct wall of the second air duct and the other end extending away from the duct wall of the second air duct. The lengths of the plurality of air guide plates extending away from the duct wall of the second air duct increase sequentially from top to bottom in the vertical direction.

[0018] In this embodiment, since the second air duct is distributed vertically, when cold air is delivered from the upper end to the lower end of the second air duct, the pressure of the cold air increases towards the lower end of the second air duct. By setting the length of the air guide plate structure away from the air duct wall to increase from top to bottom, while guiding the air to the air outlet of the partition plate, the gap between the air guide plate and the air duct wall on the opposite side can form a throttling effect, thereby reducing the pressure of the cold air in each segment of space corresponding to the air outlet of each partition layer from top to bottom along the second air duct, making the pressure of the cold air in each segment of space more uniform, thereby making the amount of cold air entering each partition layer more uniform and improving the temperature uniformity of each partition layer.

[0019] In some embodiments, in the second room, the plurality of partition layers are interconnected, and the second room further includes an air outlet channel connecting the lowest vertical partition layer with the return air channel, the air outlet channel being located below the air outlet of the partition layer of the lowest vertical partition layer.

[0020] In this embodiment, the air outlet duct is located at the bottom of the air supply vents of each partition layer in the second chamber. This allows the cold air entering each partition layer to fully contact and cool the partition layer it is located in before flowing out of the air outlet duct into the return air duct. Before flowing out, the cold air in the upper partition layer can also contact and cool the lower partition layer more, further improving the cooling effect of the cold air on the partition layer.

[0021] In some embodiments, a fan disposed within the air outlet duct is also included.

[0022] This embodiment, by installing a fan in the air outlet duct, allows the cold air from the second chamber to flow more smoothly from the second chamber to the return air duct, improving the airflow efficiency in the duct and enabling the cold air to enter the refrigeration unit for cooling in a timely manner, thus maintaining the continuous temperature regulation of each partition layer.

[0023] In some embodiments, a first air storage space is provided on the cabinet and connected between the first compartment and the first air duct, through which the first air duct delivers cold air into the first compartment.

[0024] In this embodiment, a first air storage space is set up, which can store cold air. When the first room is not ventilated with cold air, the cold air stored in the first air storage space can play an indirect pre-cooling role. When the air supply to the first room is turned on, the cold air in the first air storage space can be quickly delivered to the first room, and the temperature regulation of the first room can be started more quickly.

[0025] In some embodiments, a chamber passage valve is further included for controlling the connection and disconnection between the first air storage space and the first compartment.

[0026] In this embodiment, by opening the air chamber channel valve, the connection between the first air storage space and the first chamber can be achieved, allowing cold air to be supplied from the first air storage space to the first chamber. Conversely, by opening the air chamber channel valve on the pipe wall, the connection between the first air storage space and the first chamber is broken, allowing the cold air supplied from the air supply channel to the first air storage space to be stably stored there, facilitating rapid activation when cold air is supplied to the first chamber again.

[0027] In some embodiments, the second compartment includes a plurality of partition layers arranged vertically from top to bottom, the second air duct extends vertically, and the freezer also includes a plurality of air inlets arranged vertically from top to bottom and corresponding to and communicating with the plurality of partition layers. Each air inlet includes a partition layer inlet disposed on the wall of the corresponding partition layer. Each partition layer inlet includes a plurality of air inlet components arranged vertically from top to bottom. Each air inlet component includes a plurality of air inlet holes evenly distributed horizontally, and the air inlet holes of adjacent air inlet components are staggered horizontally from top to bottom.

[0028] In this embodiment, multiple air inlet components are arranged vertically from top to bottom, and each air inlet component is provided with multiple air inlets evenly distributed horizontally. The adjacent air inlet components are staggered. When the cold air delivered by the second air duct enters the partition layer through the partition layer inlet, the multiple air inlet components can make the cold air enter the partition layer more evenly, thereby improving the uniformity of temperature regulation of the partition layer.

[0029] In some embodiments, the plurality of air inlets of the air inlet assembly include circular holes and elongated holes that are alternately distributed in the horizontal direction.

[0030] In this embodiment, by setting an air intake component with alternating circular and elongated holes, the wind speed and vibration of the cold air will be different after passing through adjacent circular and elongated holes. The cold air passing through adjacent circular and elongated holes will disturb each other, thereby increasing the influence space of the cold air in a local area, and further improving the uniformity of the temperature regulation of the partition layer by the cold air.

[0031] Based on the freezer provided by this utility model, by setting up a refrigeration device and a first air duct and a second air duct to deliver cold air to the first and second compartments, and by setting up an air damper device to adjust the size of the air duct inlet of the first and second air ducts, the air volume of cold air entering the first and second compartments can be controlled by adjusting the size of the air duct inlet of the first and second air ducts. Thus, the temperature of the first and second compartments can be adjusted using a single refrigeration device, which is reliable and has a lower cost.

[0045] The freezer in this embodiment includes a cabinet body 100, a first compartment 1, a second compartment 2, an air supply duct 3, a return air duct 4, a refrigeration unit 5, and an air damper device 6.

[0046] The first compartment 1 is located on the cabinet 100; the second compartment 2 is located on the cabinet 100. The first compartment and the second compartment are different compartments. In the embodiment shown in the figure, the first compartment and the second compartment are respectively the upper compartment located above and the lower compartment located below.

[0047] The air supply duct 3 is located on the cabinet 100. The air supply duct 3 includes a first air duct and a second air duct 32 that are respectively connected to the first chamber 1 and the second chamber 2. The first air duct and the second air duct 32 are respectively used to supply cold air to the first chamber 1 and the second chamber 2.

[0048] The return air duct 4 is located on the cabinet 100. The return air duct 4 is connected to the first compartment 1 and the second compartment 2. The return air duct 4 is used to receive the cold air output from the first compartment 1 and the second compartment 2.

[0049] The refrigeration unit 5 is installed on the cabinet 100. The refrigeration unit includes a return air inlet 52 connected to the return air duct 4 and an air outlet 51 connected to the air supply duct 3. The refrigeration unit 5 is configured to receive the cold air delivered by the return air duct 4 through the return air inlet 52, cool the received cold air, and then send it into the air supply duct 3 through the air outlet 51.

[0050] In this embodiment of the freezer, the air supply duct delivers cold air from the refrigeration unit to the first and second compartments respectively through the first and second air ducts. The cold air entering the first and second compartments cools them down, and then flows out of the first and second compartments into the return air duct 4. The return air duct then delivers the cold air to the refrigeration unit through the return air inlet 52. The refrigeration unit cools the received cold air and then delivers the cooled cold air through the air outlet 51 to the air supply duct to continue cooling the first and second compartments. In this embodiment, the refrigeration unit 5 is used to cool the cold air. In some embodiments, the refrigeration unit includes a compressor, a condenser, an expansion valve, an evaporator, and refrigerant flowing therein. In the embodiment shown in the figure, it also includes a cooling fan 81 for dissipating heat from the condenser. The cold air is cooled by the refrigerant flowing through the evaporator 82.

[0051] A damper device 6 is installed on the air supply duct 3. The damper device 6 is used to adjust the size of the inlet of the first air duct and the inlet of the second air duct 32 to control the airflow of the cold air output from the air outlet 51 into the first and second air ducts 32 respectively. By controlling the size of the inlets of the first and second air ducts, the damper device 6 can control the amount of air entering the first and second air ducts, and correspondingly control the amount of air entering the first and second chambers, thereby regulating the temperature of the first and second chambers by controlling the airflow. In the embodiment shown in the figure, the damper device 6 is an electric damper, specifically including a first damper 61 for controlling the size of the inlet of the first air duct and a second damper 62 for controlling the size of the inlet of the second air duct.

[0052] The freezer in this embodiment is equipped with a refrigeration device 5 and a first air duct and a second air duct 32 for supplying cold air to the first compartment 1 and the second compartment 2. An air damper device 6 is also provided to adjust the size of the air duct inlet of the first air duct and the air duct inlet of the second air duct 32. By adjusting the size of the air duct inlet of the first air duct and the air duct inlet of the second air duct 32, the air volume of cold air entering the first compartment 1 and the second compartment 2 can be controlled. Thus, the temperature of the first compartment 1 and the second compartment 2 can be adjusted using a single refrigeration device 5, which is reliable and has a lower cost.

[0053] In some embodiments, the freezer further includes a first temperature detector 71 for detecting the room temperature of the first compartment 1, a second temperature detector 72 for detecting the room temperature of the second compartment 2, and a controller. The controller is signal-connected to the first temperature detector 71, the second temperature detector 72, and the damper device 6. The controller is configured to control the damper device 6 to adjust the size of the air duct inlet of the first air duct and the air duct inlet of the second air duct 32 based on the detection results of the first temperature detector 71 and the second temperature detector 72.

[0054] In this embodiment, the controller can monitor the room temperatures of the first and second rooms in real time based on the detection results of the first temperature detector 71 and the second temperature detector 72. This allows for automatic control of the inlet sizes of the first and second air ducts. For example, when the room temperature of the first room is higher than the set temperature (as detected by the first temperature detector 71), the controller controls the damper to increase the opening of the inlet of the first air duct, increasing the airflow of cold air into the first room, thus lowering the room temperature. Conversely, when the room temperature is lower than the set temperature (as detected by the first temperature detector 71), the controller controls the damper to decrease the opening of the inlet of the first air duct, reducing the airflow of cold air into the first room, thus lowering the room temperature.

[0055] In some embodiments, the second compartment 2 includes a plurality of partition layers arranged vertically from top to bottom, such as... Figure 1 and Figure 2 As shown, the second compartment includes a first partition layer 211, a second partition layer 212, a third partition layer 213, and a fourth partition layer 214, distributed sequentially from top to bottom. In the embodiment shown, the first compartment also includes two partition layers, namely an upper partition layer 111 and a lower partition layer 112, which are interconnected. By setting a partition extending horizontally in the first compartment, the first compartment is divided into two partition layers. Similarly, in the embodiment shown, by setting three partitions in the second compartment, the second compartment is divided into four interconnected partition layers. The second air duct 32 extends vertically. The freezer also includes multiple air inlets, each corresponding to and connected to the multiple partition layers, distributed sequentially from top to bottom in the vertical direction. That is, each partition layer is provided with one air inlet, and each air inlet is responsible for supplying air to one partition layer. The height distribution of the air inlets is the same as the height distribution order of the corresponding partition layers. The air inlet includes a partition layer air outlet 321 disposed on the duct wall of the second air duct 32. The partition layer air outlet 321 is used to deliver the cold air delivered by the second air duct 32 to the corresponding partition layer. The freezer also includes a plurality of air guide structures 322 corresponding one-to-one with the partition layer air outlets 321 of the plurality of air inlets. The air guide structures 322 and their corresponding partition layer air outlets 321 are located on the same side of the duct wall of the second air duct 32, and the air guide structures 322 are located below their corresponding partition layer air outlets 321 to guide the air delivered by the second air duct 32 into their corresponding partition layer air outlets 321.

[0056] In this embodiment, the second air duct extends vertically. When the second air duct delivers cold air from top to bottom, the flow rate of the cold air entering the corresponding partition layer of the second room through the multiple partition layer air outlets 321 on the duct wall will be uneven. Each partition layer air outlet 321 is provided with an air guide structure below it, which can adjust the amount of cold air entering each partition layer air outlet 321. Thus, by setting the air guide structure, the air volume delivered by the second air duct 321 to each partition layer air outlet can be made more uniform.

[0057] In some embodiments, such as Figure 1 and Figure 2 As shown, the air guiding structure 322 includes an air guide plate whose one end is connected to the duct wall of the second air duct 32 and whose other end extends away from the duct wall of the second air duct 32. In the embodiment shown, the other end of the air guiding structure 322 is a free end, extending horizontally away from the duct wall where the corresponding partition layer air outlet is located. Vertically from top to bottom, the lengths of the multiple air guide plates extending away from the duct wall of the second air duct 32 increase sequentially, that is, the gap between the air guide plate and the duct wall of the second air duct 32 opposite to the partition layer air outlet becomes smaller and smaller.

[0058] In this embodiment, since the second air duct is distributed vertically, when cold air is delivered from the upper end to the lower end of the second air duct, the pressure of the cold air increases towards the lower end of the second air duct. By setting the length of the air guide plate structure away from the air duct wall to increase from top to bottom, while guiding the air to the air outlet of the partition plate, the gap between the air guide plate and the air duct wall on the opposite side can form a throttling effect, thereby reducing the pressure of the cold air in each segment of space corresponding to the air outlet of each partition layer from top to bottom along the second air duct, making the pressure of the cold air in each segment of space more uniform, thereby making the amount of cold air entering each partition layer more uniform and improving the temperature uniformity of each partition layer.

[0059] In some embodiments, such as Figure 1 and Figure 2 As shown, in the second compartment 2, multiple partition layers are interconnected. The second compartment 2 also includes an air outlet duct 33 connecting the lowest vertical partition layer to the return air duct 4. The air outlet duct 33 is located below the air outlet 321 of the lowest vertical partition layer. In the embodiment shown, the second compartment includes a first partition layer 211, a second partition layer 212, a third partition layer 213, and a fourth partition layer 214 distributed from top to bottom. The fourth partition layer 214 is the lowest partition layer, and the air outlet duct 33 is located below the air outlet 321 of the fourth partition layer 214.

[0060] In this embodiment, the air outlet duct is located at the bottom of the air supply vents of each partition layer in the second chamber. This allows the cold air entering each partition layer to fully contact and cool the partition layer it is located in before flowing out of the air outlet duct into the return air duct. Before flowing out, the cold air in the upper partition layer can also contact and cool the lower partition layer more, further improving the cooling effect of the cold air on the partition layer.

[0061] In some embodiments, the freezer also includes a fan 34 disposed in the air outlet duct 33. The fan 34 may be a centrifugal fan, which drives air to flow from the second compartment to the air outlet duct and then sends the air to the return air duct.

[0062] This embodiment, by installing a fan in the air outlet duct, allows the cold air from the second chamber to flow more smoothly from the second chamber to the return air duct, improving the airflow efficiency in the duct and enabling the cold air to enter the refrigeration unit for cooling in a timely manner, thus maintaining the continuous temperature regulation of each partition layer.

[0063] In some embodiments, such as Figure 5 As shown, the freezer also includes a first air storage space 73 disposed on the cabinet 100, connecting the first compartment 1 and the first air duct. The first air duct delivers cold air into the first compartment 1 through the first air storage space 73. The first air storage space 73 is located in the flow path of the first air duct delivering cold air to the first compartment. The first air duct first delivers cold air to the first air storage space, and then delivers it to the first compartment through the first air storage space. The first air storage space is a space capable of storing a certain amount of cold air. As shown in the figure, it is a rectangular space. In some embodiments, it can also be a cylindrical space, a spherical space, or an irregular polyhedral space, etc.

[0064] In this embodiment, a first air storage space is set up, which can store cold air. When the first room is not ventilated with cold air, the cold air stored in the first air storage space can play an indirect pre-cooling role. When the air supply to the first room is turned on, the cold air in the first air storage space can be quickly delivered to the first room, and the temperature regulation of the first room can be started more quickly.

[0065] In some embodiments, the freezer also includes an air chamber passage valve for controlling the connection and disconnection between the first air storage space 73 and the first compartment 1.

[0066] In this embodiment, by opening the air chamber channel valve, the connection between the first air storage space 73 and the first chamber 1 can be achieved, allowing cold air to be supplied from the first air storage space 73 to the first chamber. By opening the air chamber channel valve on the pipe wall, the connection between the first air storage space 73 and the first chamber 1 is broken, allowing the cold air supplied from the air supply channel to the first air storage space to be stably stored there, facilitating rapid activation when cold air is supplied to the first chamber again.

[0067] In some embodiments, such as Figures 2 to 4 As shown, the second compartment 2 includes multiple partition layers arranged vertically from top to bottom. The second air duct 32 extends vertically. The freezer also includes multiple air inlets arranged vertically from top to bottom, corresponding to and connected to each partition layer. Each air inlet includes a partition layer inlet 35 located on the wall of the corresponding partition layer. Each partition layer inlet 35 includes multiple air inlet components 350 arranged vertically from top to bottom. Each air inlet component 350 includes multiple air inlets evenly distributed horizontally. The air inlets of adjacent air inlet components 350 are staggered horizontally. In the embodiment shown, each air inlet component includes the same type and size of air inlets. In the embodiment shown, the air inlet also includes a partition layer air outlet 321 located on the duct wall of the second air duct 32. The cold air transported by the second air duct passes through the partition layer air outlet 321 through the duct wall of the second air duct, and then through the partition layer inlet to each partition layer. In some embodiments, the air inlet may only include the inlet of the partition layer, meaning that the wall surface of the partition layer shares the same wall surface as the duct wall of the second air duct.

[0068] In this embodiment, multiple air inlet components are arranged vertically from top to bottom, and each air inlet component is provided with multiple air inlets evenly distributed horizontally. The adjacent air inlet components are staggered. When the cold air delivered by the second air duct enters the partition layer through the partition layer inlet, the multiple air inlet components can make the cold air enter the partition layer more evenly, thereby improving the uniformity of temperature regulation of the partition layer.

[0069] In some embodiments, the air inlet assembly 350 includes a plurality of air inlets including circular holes 351 and elongated holes 352 that are alternately distributed in the horizontal direction.

[0070] In this embodiment, by setting an air intake component with alternating circular and elongated holes, the wind speed and vibration of the cold air will be different after passing through adjacent circular and elongated holes. The cold air passing through adjacent circular and elongated holes will disturb each other, thereby increasing the influence space of the cold air in a local area, and further improving the uniformity of the temperature regulation of the partition layer by the cold air.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
