Description

Technical Field

[0001] The present application relates to the field of household appliances, and in particular to an operating method of a refrigeration appliance and a refrigeration appliance. Background Art

[0002] Nowadays, refrigeration appliances have entered thousands of households, such as refrigerators, wine cabinets, etc. People's demands for the functions of refrigeration appliances are becoming more and more diverse.

[0003] For example, taking refrigerators as an example, refrigerators with multiple storage areas are more popular with users. It is known that drawers can be arranged in the refrigerator compartment of the refrigerator to separate multiple relatively independent storage areas. These storage areas usually have basically the same or related temperatures. In addition, refrigerators with multiple independent compartments are also known. For example, a refrigerator may be provided with a refrigerator compartment, a freezer compartment, and a variable temperature chamber. The independent compartments may be cooled by independent refrigeration systems, or be equipped with independent air ducts. This will lead to a more complex refrigeration circuit and air duct structure of the refrigerator, and a significant increase in manufacturing costs. In the refrigerator, the temperature control between each storage area or each compartment is coupled with each other, making the operation method of the refrigerator very complicated.

[0004] Currently, refrigerators with multiple temperature zones have problems such as complex structure, inability to independently and accurately control the temperature of each temperature zone, and complex operation methods. Summary of the invention

[0005] An object of the embodiments of the present application is to provide an improved refrigeration appliance so as to overcome at least one of the above-mentioned deficiencies in the prior art.

[0006] According to the first aspect of the present application, an embodiment of the present application provides an operating method of a refrigeration appliance. The refrigeration appliance is provided with: a compartment having a storage space, the storage space comprising a first storage space and a second storage space separated in a heat-insulated manner, the first storage space being provided with a connecting opening so that gas can flow into and / or out of the first storage space via the connecting opening; a first fan for driving gas in the second storage space to enter the first storage space via the connecting opening; and a heater for heating the first storage space. The operating method includes: selectively operating or shutting down the first fan and the heater so as to achieve a desired storage mode of the first storage space, wherein the storage mode of the first storage space includes a first storage mode having a first target temperature set independently of the temperature of the second storage space.

[0007] By means of the operating method, a method is provided for forming a plurality of temperature zones in a single compartment of a refrigeration appliance, wherein the operating temperatures of the different temperature zones can be controlled independently and accurately. The first storage space is separated from the second storage space in the same compartment by thermal insulation on the one hand, and gas can be introduced from the second storage space by means of the first fan on the other hand. By selectively operating or shutting down the first fan and the heater, the temperature of the first storage space can be made independent of the temperature of the second storage space and have a large adjustment range. It is particularly advantageous that the refrigeration appliance can be operated in a simple and easy-to-implement method.

[0008] According to an optional embodiment of the present application, in the operating method, the operating state of the heater can be determined according to the actual temperature and / or target temperature and / or storage mode of the first storage space and is independent of the actual temperature, target temperature and storage mode of the second storage space. Alternatively or additionally, in the operating method, the operating state of the first fan can be determined according to the actual temperature and / or target temperature and / or storage mode of the first storage space and is independent of the actual temperature, target temperature and storage mode of the second storage space. In the operating method of the refrigeration appliance, the temperature control of the first storage space can be performed independently of the second storage space.

[0009] According to an optional embodiment of the present application, the operating method may include rotating the first fan so as to drive the gas to flow into and / or out of the first storage space via the communication opening, and stopping the first fan so as to stop the airflow between the first storage space and the rest of the storage space, wherein the communication opening may remain open so that the first storage space and the second storage space are always connected by means of the communication opening fluid, and / or the communication opening may have a serpentine path including at least one bend so that the gas can pass through the communication opening along the serpentine path under the drive of the first fan. The refrigeration appliance may not be provided with a first damper for controlling the opening and closing state of the communication inlet. In the case of omitting the first damper, the temperature of the first storage space can still be accurately controlled. By omitting the first damper, the cost of the refrigeration appliance and the complexity of the operating method of the refrigeration appliance can be reduced. The operating method does not need to consider the opening and closing state of the communication opening. The first damper for controlling the opening and closing state of the communication inlet will reduce the volume of the first storage space. In order to control the opening and closing state of the first damper, it is also necessary to realize the electrical connection between the first damper and the power supply and / or control device of the refrigeration appliance. Therefore, by omitting the first damper, the structure can be greatly simplified and the available volume in the storage space can be increased.

[0010] According to an optional embodiment of the present application, the operation method may include: placing the first storage space in a first storage mode so as to achieve a first target temperature in the first storage space that is higher than the actual temperature and / or target temperature of the second storage space. To this end, the actual temperature of the first storage space may be obtained, and when the actual temperature of the first storage space is lower than the first target temperature of the first storage space, the heater is operated and the first fan is operated in a first working state, and when the actual temperature of the first storage space is higher than the first target temperature of the first storage space, the heater is turned off and the first fan is operated in a second working state. In the first storage mode, the heater is operated so as to heat the first storage space as needed, and the first fan may be turned on to prevent condensation. Since the first storage space has a relatively high temperature in the first storage mode, the possibility of condensation in the first storage space increases. To this end, the first fan may be operated so as to drive gas to flow into and out of the first storage space to prevent condensed water from accumulating in or near the first storage space. In the first storage mode, the setting of the working state of the first fan is adapted to its purpose of preventing condensation.

[0011] According to an optional embodiment of the present application, the first fan operates at a lower on / off ratio or a lower operating power in the first operating state compared to the second operating state.

[0012] According to an optional embodiment of the present application, the first fan operates at an on-off ratio of 1%-5%, particularly 1%-2%, in the first working state. Alternatively or additionally, the first fan operates at an on-off ratio of 1%-5%, particularly 1%-2%, in the second working state. As a result, gas can be intermittently introduced into the first storage space to prevent condensation. In the first storage mode, running the first fan does not or is not intended to change the temperature difference between the first storage space and the second storage space.

[0013] According to an optional embodiment of the present application, the operation method may include: placing the first storage space in a second storage mode so as to achieve a second target temperature lower than the first target temperature in the first storage space, wherein the heater is turned off and the first fan operates in a third working state. Thus, the first storage space can be made multifunctional. The first storage space can be set to operate in different storage modes for storing different types of items. In particular, the temperature control of the multifunctional first storage space can be achieved in a simple manner.

[0014] According to an optional embodiment of the present application, the operating method may include: placing the first storage space in a second storage mode so as to achieve a second target temperature lower than the first target temperature in the first storage space, wherein the heater is turned off and the working state of the first fan is adjusted according to the actual temperature of the first storage space. Here, the first fan is deactivated when the actual temperature of the first storage space is lower than a predetermined temperature threshold, and the first fan is operated in a third working state when the actual temperature of the first storage space is higher than a predetermined temperature threshold. The predetermined temperature threshold may, for example, be lower than the settable minimum temperature of the second storage space. This helps to reduce the development and manufacturing costs of the refrigeration appliance. During the normal operation of the refrigeration appliance, the actual temperature of the first storage space will not be lower than the predetermined temperature threshold, so that the first fan will not be deactivated in the second storage mode.

[0015] According to an optional embodiment of the present application, compared with the third working state, when the first storage space is in the first storage mode, the first fan operates with a lower start-stop ratio or a lower working power. The first fan can operate with a higher start-stop ratio or a higher power in the third working state, so that sufficient gas can be introduced from the second storage space into the first storage space and reduce the temperature of the first storage space. In the first storage mode and the second storage mode, the main function of running the first fan is different, and the working state of the first fan is also different accordingly. In the second storage mode, the first fan is mainly used to introduce cooling gas from the second storage space to reduce the temperature in the first storage space. Optionally, the start-stop ratio of the first fan in the third working state is more than 10 times the start-stop ratio of the first fan when the first storage space is in the first storage mode. For example, the first fan operates with an start-stop ratio of more than 15% in the third working state.

[0016] According to an optional embodiment of the present application, the communication opening may include a first communication outlet for allowing gas to flow out of the first storage space, and the first communication outlet is located on a side of the first storage space opposite to the second storage space. The operation method may include: turning on the first fan to drive the gas to flow out of the first storage space through the first communication outlet, and leave the storage space through the first return air passage located outside the second storage space through the return air port of the storage space. When the first storage space is in the first storage mode, the higher temperature gas flowing out through the first communication outlet will not affect the temperature in the second storage space.

[0017] According to an optional embodiment of the present application, the communication opening may include a second communication outlet for allowing gas to flow out of the first storage space. The compartment may be provided with an air inlet for introducing cooling gas into the compartment. The air inlet may be arranged at the first compartment wall of the compartment. The second communication outlet may be arranged adjacent to the air inlet and facing the first compartment wall. The operation method may include: turning on the first fan to drive the gas to flow out from the first storage space through the second communication outlet, and to leave the storage space through the return air outlet of the storage space through the second return air passage located outside the second storage space. Driven by the first fan, the gas flowing out from the first storage space through the second communication outlet blows toward the first compartment wall, and flows toward the return air outlet through the gap between the first compartment wall and the heat-insulating shell. Thereby, condensation water can be prevented from accumulating here.

[0018] According to an optional embodiment of the present application, the heater may be arranged at the bottom of the first storage space. In the operation method, the working state of the first fan may be independent of the working state of the heater. The heater can heat the first storage space uniformly without relying on the first fan. Thus, the desired temperature can be achieved in the first storage space with a simple and easy-to-implement operation method.

[0019] According to an optional embodiment of the present application, the refrigeration appliance may be provided with a second fan for driving the cooling gas to flow into the storage space and / or a second damper for controlling the flow of the cooling gas flowing into the storage space. The operation method may include: determining the working state of the second fan and / or the second damper according to the actual temperature and / or the target temperature of the second storage space, independent of the actual temperature, the target temperature and the storage mode of the first storage space. The working state of the second fan and / or the second damper may be independent of the first storage space. In other words, in the operation method of the refrigeration appliance, the temperature control of the second storage space may be performed independently of the first storage space. In particular, through the operation method, the temperature control of the first storage space and the temperature control of the second storage space can be decoupled from each other. In the case where the first storage space is removed from the compartment or the first storage space is not provided in the compartment, the refrigeration appliance can operate normally without changing the arrangement and control method of the second fan and / or the second damper. This can reduce costs.

[0020] According to a first aspect of the present application, an embodiment of the present application provides a refrigeration appliance, which is provided with: a compartment having a storage space, the storage space comprising a first storage space and a second storage space separated in a heat-insulated manner, the first storage space being provided with a communication opening, so that gas can flow into and / or out of the first storage space via the communication opening; a first fan for driving gas in the second storage space to enter the first storage space via the communication opening; and a heater for heating the first storage space. The refrigeration appliance is configured to be able to perform the operation method according to the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] In order to make the technical problems, technical solutions and beneficial technical effects to be solved by the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the scope of protection of the present application.

[0067] First, for ease of understanding, let's go back to the description in the background technology section. The refrigeration appliances in the prior art have problems such as complex refrigeration circuit structure, difficulty in independently and accurately controlling the temperatures of different temperature zones of the refrigeration appliance, and complex operating methods.

[0068] In response to at least one of the above technical problems or other possible technical problems, an exemplary embodiment of the present application provides an operating method of a refrigeration appliance. The refrigeration appliance is provided with: a compartment with a storage space, the storage space includes a first storage space and a second storage space separated in a heat-insulated manner, the first storage space is provided with a connecting opening so that gas can flow into and / or out of the first storage space through the connecting opening; a first fan for driving the gas in the second storage space to enter the first storage space through the connecting opening; and a heater for heating the first storage space. The operating method includes: selectively operating or shutting down the first fan and the heater to achieve a desired storage mode of the first storage space, wherein the storage mode of the first storage space includes a first storage mode with a first target temperature set independently of the temperature of the second storage space.

[0069] An exemplary embodiment of the present application provides a refrigeration appliance, which is provided with: a compartment with a storage space, the storage space including a first storage space and a second storage space separated in a heat-insulated manner, the first storage space being provided with a communication opening, so that gas can flow into and / or out of the first storage space via the communication opening; a first fan for driving gas in the second storage space to enter the first storage space via the communication opening; and a heater for heating the first storage space. The refrigeration appliance is configured to be able to perform the operation method according to the present application.

[0070] In order to better understand the present application, exemplary embodiments of the present application will be described below with reference to the accompanying drawings.

[0071] Before starting the detailed description, it should be pointed out that the directional terms used in the description process refer to the normal use state of the refrigeration appliance for the convenience of description and should not be understood as an absolute limitation on the corresponding features. In some drawings, the height direction H, the width direction W and the depth direction D, which are perpendicular to each other, are schematically shown by arrows.

[0072] Figure 1A refrigeration appliance according to an exemplary embodiment of the present application is schematically shown.

[0073] from Figure 1 As can be seen in the figure, the refrigeration appliance is provided with a compartment 1, which has a storage space 10. The items to be cooled can be stored in the storage space 10 of the compartment 1. The compartment 1 can be used as a cold storage room, for example. The storage space 10 can have an approach opening that opens forward. The refrigeration appliance is provided with a door (not shown here) for closing the approach opening. The storage space 10 can be closed by a single cold storage door. When the door is open, the approach opening is open, and the user can take and place items through the approach opening. It can also be seen from the figure that the refrigeration appliance may include a plurality of compartments 1 formed in the case of the refrigeration appliance. For example, in addition to the compartment 1 used as a cold storage room, the refrigeration appliance may also include, for example, a freezer located on the left side of the cold storage room and a temperature-changing room or an ice room located below the cold storage room. The case of the refrigeration appliance separates the compartments 1.

[0074] Those skilled in the art will appreciate that the compartment 1 can also be used as a freezer, etc. In this embodiment, the refrigeration appliance can be implemented as a combined refrigerator with a refrigerator and a freezer, for example. Those skilled in the art will appreciate that the present application is also applicable to other types of refrigerators, such as a separate refrigerator or freezer. In addition, as required, the present application can also be applied to other refrigeration appliances other than refrigerators, such as a wine cabinet. The present application is particularly applicable to household refrigeration appliances.

[0075] The storage space 10 includes a first storage space 101 and a second storage space 101 separated by heat insulation. The first storage space 101 may be provided with a communication opening 21 (see Figure 2 ), so that gas can flow into and / or out of the first storage space 101 through the communication opening 21.

[0076] The refrigeration appliance may be provided with a heat-insulating housing 2, which is arranged in the compartment 1 so as to separate a first storage space 101 and a second storage space 101 in the storage space 10. A communication opening 21 may be formed in the heat-insulating housing 2.

[0077] The refrigeration appliance is further provided with a first fan 3 for driving the gas in the second storage space 101 to enter the first storage space 101 through the communication opening 21 and a heater 4 for heating the first storage space 101 .

[0078] The operation method of the refrigeration appliance includes: selectively operating or shutting down the first fan 3 and the heater 4 to achieve a desired storage mode of the first storage space 101. The storage mode of the first storage space 101 includes a first storage mode having a first target temperature set independently of the temperature of the second storage space 101.

[0079] By providing a first storage space 101 and a second storage space 102 separated by heat insulation in a single compartment 1 of a refrigeration appliance, and by selectively operating or shutting down a first fan 3 and a heater 4, the temperature in the first storage space 101 can be independently adjusted relative to the second storage space 102. Thus, a method for forming multiple temperature zones in a single compartment 1 of a refrigeration appliance is provided, and the operating temperatures of different temperature zones can be independently and accurately controlled. The first storage space 101 is separated from the second storage space 102 in the same compartment 1 by heat insulation on the one hand, and gas can be introduced from the second storage space 102 by means of the first fan 3 on the other hand. By selectively operating or shutting down the first fan 3 and the heater 4, the temperature of the first storage space 101 can be independent of the temperature of the second storage space 102 and have a large adjustment range. It is particularly advantageous that such a refrigeration appliance can be operated in a simple and easy-to-implement method.

[0080] In the first storage mode, the first storage space 101 may have an operating temperature that is significantly different from that of the second storage space 102. For example, the first storage space 101 and the second storage space 102 may have a maximum temperature difference of more than 10°C. For example, by turning on the heater 4 and turning off the first fan 3, the first target temperature of the first storage space 101 in the first storage mode may be higher than the temperature of the second storage space 102. The second storage space 102 can be used as a refrigerated space, for example, and may have an operating temperature of 2°C-8°C. The first target temperature may be, for example, between 8°C and 12°C. Thus, the first storage space 101 and the second storage space 102 may have different operating temperatures and are suitable for storing different types of items. The first storage space 101 can especially have an operating temperature higher than the conventional refrigeration temperature, thereby being able to expand the functionality of the refrigeration appliance.

[0081] Optionally, the storage mode of the first storage space 101 may include a second storage mode having a second target temperature lower than the first target temperature. Compared with the first storage mode, the first fan 3 and / or the heater 4 have different working states in the second storage mode so as to achieve different target temperatures in the first storage space 101. Compared with the first storage mode, the second storage mode may have a lower settable temperature range. Thus, the first storage space 101 may be multifunctional.

[0082] like Figure 1 As shown, the refrigeration appliance may be provided with a first temperature sensor 51 for detecting the temperature of the first storage space 101 and / or a second temperature sensor 52 for detecting the temperature of the second storage space 102 .

[0083] In the operation method, the working state of the heater 4 may be determined according to the actual temperature and / or target temperature and / or storage mode of the first storage space 101 and is independent of the actual temperature, target temperature and storage mode of the second storage space 102. For example, when the first storage space 101 is in the first storage mode, the heater 4 may be turned on when the actual temperature of the first storage space 101 is lower than the first target temperature of the first storage space 101, and the heater 4 may be deactivated when the actual temperature of the first storage space 101 is higher than the first target temperature of the first storage space 101.

[0084] Alternatively or additionally, in the operating method, the operating state of the first fan 3 may be determined according to the actual temperature and / or target temperature and / or storage mode of the first storage space 101 and is independent of the actual temperature, target temperature and storage mode of the second storage space 102 .

[0085] The working state of the first fan 3 can be set to be off, running at a specific working power, or running at a specific on-off ratio, etc. The "on-off ratio" can represent the ratio of the time that the running device is in the on state to the time that it is in the off state. The on-off ratio is a value greater than 0. It should be understood that "the first fan 3 is running" does not mean that the first fan 3 always keeps rotating when running, but that the running first fan 3 can be turned on and off alternately at a certain rhythm. "The first fan 3 is off" means that the first fan 3 will not be enabled. The above description of "running" and "off" is similarly applicable to the heater 4.

[0086] Optionally, when the first storage space 101 is in the first storage mode, the first fan 3 is operated with a lower on / off ratio or lower power to prevent condensation.

[0087] When the first storage space 101 is in the second storage mode, the heater 4 may remain turned off, and the first fan 3 may be operated with a higher on / off ratio or a higher power.

[0088] Optionally, the refrigeration appliance is further provided with a second fan 71 for driving cooling gas to flow into the storage space 10. The operation method comprises: independently of the actual temperature, target temperature and storage mode of the first storage space 101, determining the working state of the second fan 71 according to the actual temperature and / or target temperature of the second storage space 102.

[0089] For example, the refrigeration appliance may include an evaporator chamber 61 and an evaporator 62 arranged in the evaporator chamber 61. The gas cooled by the evaporator 62 may be guided to the storage space 10 of the compartment 1 to reduce the temperature. The evaporator chamber 61 may be located outside the compartment 1. For example, the evaporator chamber 61 may be arranged in another compartment 1. The refrigeration appliance may include a supply channel 63 for connecting the evaporator chamber 61 to the compartment 1 so as to supply the gas cooled by the evaporator 62 to the compartment 1 and a return channel 64 for guiding the gas in the storage space 10 of the compartment 1 to flow to the evaporator 62.

[0090] When the actual temperature in the second storage space 102 is detected to be high by the second temperature sensor 52, for example, the second fan 71 may be activated or the working efficiency of the second fan 71 may be increased, thereby increasing the amount of cooling gas supplied to the storage space 10. Thus, the temperature of the second storage space 102 may be lowered without affecting the first storage space 101.

[0091] Optionally, the refrigeration appliance is further provided with a second damper 72 for controlling the flow of cooling gas flowing into the storage space 10. The operation method may include: determining the working state of the second damper 72 according to the actual temperature and / or the target temperature of the second storage space 102, independently of the actual temperature, the target temperature and the storage mode of the first storage space 101. The second damper 72 for controlling the flow of cooling gas flowing into the storage space 10 may be arranged in the supply channel 63, for example, so that the opening and closing state of the supply channel 63 can be switched.

[0092] Figure 2 The compartment 1 of the refrigeration appliance according to the exemplary embodiment of the present application is schematically shown in a cross-sectional view, wherein the cross-sectional position can be referred to as Figure 1 Section line AA is shown.

[0093] like Figure 2 As shown, the heat-insulating housing 2 can be arranged in the compartment 1 to separate the first storage space 101 and the second storage space 102 in the storage space 10 in a heat-insulating manner. The heat-insulating housing 2 can be arranged at the bottom of the storage space 10, so that the first storage space 101 is located below the second storage space 102.

[0094] The heat-insulating housing 2 completely surrounds the first storage space 101 in all directions, for example. The heat-insulating housing 2 may include at least one heat-insulating wall surrounding the first storage space 101. The at least one heat-insulating wall, for example, includes a heat-insulating rear wall 22 located behind the first storage space 101, a heat-insulating front wall opposite to the heat-insulating rear wall 22, a heat-insulating top wall 23 located above the first storage space 101, a heat-insulating bottom wall 24 opposite to the heat-insulating top wall 23, and heat-insulating side walls 25 located on both sides of the first storage space 101. Optionally, the heat-insulating housing 2 may also surround the first storage space 101 together with the compartment wall of the compartment 1. For example, the heat-insulating housing 2 may include a heat-insulating top wall 23 and a heat-insulating rear wall 22, and the first storage space 101 is bounded by the compartment wall at the bottom and on both sides.

[0095] The heat-insulating housing 2 may include at least a heat-insulating top wall 23 that delimits the first storage space 101 at the top. In the height direction H, the heat-insulating top wall 23 is located between the first storage space 101 and the second storage space 102 and separates the two. In another embodiment, the second storage space 102 of the other space may also be arranged side by side with the first storage space 101 along the width direction W.

[0096] It is particularly advantageous that the first storage space 101 is located at the bottom of the storage space 10. In the first storage mode, the first storage space 101 may have a higher temperature than the second storage space 102 located above it. Since the density of hot air is smaller and the density of cold air is larger, the first storage space 101 being located below the second storage space 102 is conducive to making the temperature distribution of the second storage space 102 more uniform, otherwise the upper and lower temperature differences in the second storage space 102 may be aggravated. In addition, in the case of switching from the first storage mode to the second storage mode, the first storage space 101 being located at the bottom of the storage space 10 helps to shorten the time to complete the mode switching.

[0097] The cooling gas in the second storage space 102 may flow into the first storage space 101 through the communication opening 21 driven by the first fan 3. For example, the communication opening 21 may include a communication inlet 211 for introducing gas from the second storage space 102 into the first storage space 101. The heat-insulating housing 2 may include a heat-insulating rear wall 22 that bounds the first storage space 101 at the rear. The communication inlet 211 may, for example, be open to the second storage space 102 at the heat-insulating rear wall 22. A larger gap may be left behind the heat-insulating rear wall 22, and the communication inlet 211 is open to the second storage space 102, so that sufficient gas can be introduced into the first storage space 101 when needed. Alternatively or additionally, the communication inlet 211 may also be provided in other heat-insulating walls of the heat-insulating housing 2, such as the heat-insulating top wall 23.

[0098] The first fan 3 can be particularly arranged in the heat-insulating housing 2 and can be removed from the compartment 1 along with the heat-insulating housing 2. For example, the first fan 3 can be mounted to the heat-insulating rear wall 22 and opposite to the communication inlet 211. When the first fan 3 is turned on, the gas in the second storage space 102 can be sucked into the first storage space 101. With the help of the first fan 3, the temperature in the first storage space 101 can be more accurately controlled and adjusted. In addition, the first fan 3 can also be used to adjust the humidity in the first storage space 101.

[0099] The heater 4 may be located at the bottom of the first storage space 101. The heater 4 may be particularly arranged in the insulating bottom wall 24 of the insulating shell 2. When the heater 4 is turned on, the hot air heated by the heater 4 flows upward in the first storage space 101, so that the first storage space 101 is evenly heated. Therefore, when the heater 4 is turned on, the first fan 3 does not have to be turned on synchronously with the heater 4. In the operating method, the working state of the first fan 3 may be independent of the working state of the heater 4. The first fan 3 is not arranged at the bottom of the first storage space 101, but may be located at the top, left and right sides or rear of the first storage space 101, so as not to be adjacent to the heater 4. The first fan 3 and the heater 4 may be arranged at different insulating walls. In addition, the heater 4 is arranged on the side opposite to the second storage space 102, so as to prevent the heater 4 from affecting the temperature in the second storage space 102.

[0100] Figure 3 The flowchart of the operating method of the refrigeration appliance according to the exemplary embodiment of the present application is schematically shown. Figure 4 The structure block diagram of a refrigeration appliance according to an exemplary embodiment of the present application is schematically shown.

[0101] like Figure 3 As shown, the operating method may include steps S1-S3.

[0102] In step S1, the operation mode of the first storage space 101 may be determined. The operation mode of the first storage space 101 may be determined, for example, according to a selection operation of a user. As an example, the refrigeration appliance may include an input device 8 for receiving a selection operation of a user, such as Figure 4 shown.

[0103] The input device 8 includes, for example, a button or a touch screen provided in the refrigeration appliance. In response to a selection operation by the user, a control signal corresponding to the selection operation may be generated. The selection operation may be used to select, for example, a storage mode and / or a target temperature of the first storage space 101.

[0104] The input device 8 may also receive the user's selection operation by receiving a wireless signal from a removable device, such as a mobile phone, etc. The refrigeration appliance may include a control device 9. The control device 9 may include a memory and a processor, wherein the memory stores a computer program, and when the computer program is executed by the processor, the processing device can cause the refrigeration appliance to operate according to the operation method.

[0105] The control device 9 can be communicatively connected to various components of the refrigeration appliance, such as the input device 8, the first fan 3, the heater 4 or various sensors for detection, so as to detect and / or control the operating status of each component, see Figure 4 For example, the control device 9 may be communicatively connected to the input device 8, so as to determine the operation mode of the first storage space 101 according to the user's selection operation received by the input device 8. The control device 9 may also optionally obtain a first target temperature of the first storage space 101.

[0106] When it is determined that the operation mode of the first storage space 101 is the first storage mode, step S2 may be performed. In step S2, the first storage space 101 may be placed in the first storage mode so as to achieve a first target temperature in the first storage space 101.

[0107] To this end, the heater 4 and the first fan 3 may be selectively operated or turned off to achieve a first target temperature set independently of the temperature of the second storage space 102 in the first storage space 101. The heater 4 and the first fan 3 may be operated or turned off in response to a control signal of the control device 9.

[0108] The first target temperature may be set by the user. The first target temperature may be higher than the actual temperature and / or the target temperature of the second storage space 102. In the first storage mode of the first storage space 101, the settable temperature range of the first storage space 101 may be above the settable maximum temperature of the second storage space 102. For example, if the settable maximum temperature of the second storage space 102 is 8°C, the first storage mode of the first storage space 101 may have a temperature range of 8°C-12°C.

[0109] When it is determined that the operation mode of the first storage space 101 is the second storage mode, step S3 may be performed. In step S3, the first storage space 101 may be placed in the second storage mode, so that a second target temperature lower than the first target temperature is achieved in the first storage space 101. The second target temperature of the second storage mode may be, for example, between 2°C and 8°C.

[0110] Compared with the first storage mode, the second storage mode may have a lower settable temperature range. For example, in the second storage mode, the first storage space 101 may have the same temperature as the second storage space 102. To this end, the heater 4 may be turned off. The first fan 3 may be operated as needed.

[0111] The first storage space 101 can be set to work in different storage modes to store different types of items. Thus, the first storage space 101 can be multifunctional. For example, the first storage space 101 in the first storage mode is particularly suitable for storing tropical fruits or red wine, or for thawing frozen items; the first storage space 101 in the second storage mode is particularly suitable for storing health products, medicines or skin care products.

[0112] Figure 5 The flowchart of step S2 of the operating method of the refrigeration appliance according to the exemplary embodiment of the present application is schematically shown. Step S2 may include steps S21-S24, for example.

[0113] In step S21, the actual temperature of the first storage space 101 may be acquired. The actual temperature of the first storage space 101 may be detected by the first temperature sensor 51. Figure 4 As shown, the first temperature sensor 51 can be communicatively connected to the control device 9 , thereby transmitting the detection result to the control device 9 .

[0114] In step S22, the actual temperature of the first storage space 101 may be compared with the first target temperature of the first storage space 101. Depending on the comparison result, step S23 or S24 may be performed.

[0115] When the actual temperature of the first storage space 101 is lower than the first target temperature of the first storage space 101, step S23 may be performed. In step S23, the heater 4 operates to heat the first storage space 101 as needed. The first fan 3 may be turned off, for example, to prevent gas exchange between the first storage space 101 and the second storage space 102.

[0116] Advantageously, in step S23, the first fan 3 operates in the first working state. Optionally, the first fan 3 operates at an on / off ratio of 1%-5%, particularly 1%-2% in the first working state. For example, the first fan 3 may be turned on for 2 minutes every 2 hours in the first working state. Thus, gas may be intermittently introduced into the first storage space 101, thereby preventing condensation.

[0117] In the case where the actual temperature of the first storage space 101 is higher than the first target temperature of the first storage space 101, step S24 may be performed. In step S24, the heater 4 is deactivated and the first fan 3 operates in the second working state. Optionally, the first fan 3 operates at an on-off ratio of 1%-5%, particularly 1%-2% in the second working state. For example, the first fan 3 may be turned on for 2 minutes every 2 hours in the second working state.

[0118] In the first storage mode, the first fan 3 may be turned on to prevent condensation. Since the first storage space 101 has a relatively high temperature, the possibility of condensation in the first storage space 101 increases. To this end, the first fan 3 may be operated to drive gas to flow into and out of the first storage space 101 to prevent condensed water from accumulating in or near the first storage space 101. It should be understood that in the first storage mode, operating the first fan 3 does not or is not intended to change the temperature difference between the first storage space 101 and the second storage space 102. Instead, in the first storage mode, the setting of the working state of the first fan 3 is adapted to its purpose of preventing condensation.

[0119] The operating state of the first fan 3 may be independent of the operating state of the heater 4. The heater 4 may be configured to heat the first storage space 101 uniformly without relying on the first fan 3. For example, the first operating state may be the same as the second operating state. Thus, in the first storage mode, the first fan 3 operates in a consistent operating state regardless of whether the heater 4 is running or off.

[0120] In an exemplary embodiment according to the present application, the first fan 3 can be operated at a lower on / off ratio or lower operating power in the first operating state compared to the second operating state. Therefore, when the first target temperature has not yet been reached in the first storage space 101, the heater 4 is operated and the first fan 3 is operated at a relatively low on / off ratio or low operating power; when the first target temperature is reached in the first storage space 101, the heater 4 is turned off and the first fan 3 is operated at a relatively high on / off ratio or high operating power. This also reflects that the operating states of the heater 4 and the first fan 3 are independent of each other.

[0121] In an exemplary embodiment according to the present application, in the second storage mode, the heater 4 is turned off and the first fan 3 is operated in the third working state. Optionally, in the second storage mode, the first storage space 101 may have the same temperature as the second storage space 102. To this end, the first fan 3 may be operated with a higher on-off ratio or a higher power so that sufficient gas can be introduced from the second storage space 102 into the first storage space 101 and the temperature of the first storage space 101 is reduced. In this embodiment, in the second storage mode, the working state of the first fan 3 may be independent of the actual temperature in the first storage space 101. That is, there is no need to adjust the working state of the first fan 3 according to the actual temperature in the first storage space 101 measured by the first temperature sensor 51.

[0122] Compared with the third working state, when the first storage space 101 is in the first storage mode, the first fan 3 operates with a lower on / off ratio or a lower working power.

[0123] In particular, the on / off ratio of the first fan 3 in the third working state may be more than 10 times the on / off ratio of the first fan 3 when the first storage space 101 is in the first storage mode. The first fan 3 may be operated at an on / off ratio of more than 15% in the third working state, and in particular, at an on / off ratio of more than 20%. For example, the first fan 3 may be turned on for 2 minutes every 10 minutes in the third working state.

[0124] The on / off ratio of the first fan 3 in the first working state, the second working state and / or the third working state may be preset and cannot be adjusted during operation. The on / off ratio of the first fan 3 in the first working state and / or the second working state may be pre-calibrated to be suitable for preventing condensation. The on / off ratio of the first fan 3 in the third working state may be pre-calibrated to be suitable for making the first storage space 101 and the second storage space 102 have the same temperature.

[0125] In an exemplary embodiment according to the present application, in the second storage mode, the heater 4 is turned off, and the working state of the first fan 3 can be controlled according to the actual temperature of the first storage space 101. When the actual temperature of the first storage space 101 is lower than a predetermined temperature threshold, the first fan 3 can be deactivated; when the actual temperature of the first storage space 101 is higher than the predetermined temperature threshold, the first fan 3 can be operated in a third working state.

[0126] The predetermined temperature threshold may be lower than the settable minimum temperature of the second storage space 102. For example, the settable temperature range of the second storage space 102 is 2-8°C, and the predetermined temperature threshold may be lower than 2°C, for example, set to 1°C. This helps to reduce the development and manufacturing costs of the refrigeration appliance. During the normal operation of the refrigeration appliance, the actual temperature of the first storage space 101 will not be lower than the predetermined temperature threshold, so that the first fan 3 will not be deactivated in the second storage mode. In addition, it is also possible to prevent the temperature in the first storage space 101 from being too low in the event of a malfunction.

[0127] Figure 6 Schematically shows Figure 2 A partial enlarged view of the portion framed by the dotted line.

[0128] from Figure 2 and Figure 6 It can be seen that the cooling gas in the second storage space 102 can flow into the first storage space 101 via the communication opening 21. For example, the communication opening 21 may include a communication inlet 211 disposed at the heat-insulating rear wall 22. When the first fan 3 is turned on, the gas in the second storage space 102 can flow to the communication inlet 211 driven by the first fan 3, and flow into the first storage space 101 via the communication inlet 211.

[0129] The communication opening 21 may extend along a serpentine path in the insulation wall of the insulation housing 2, wherein the serpentine path has at least one bend. The gas can pass through the communication opening 21 along the serpentine path under the drive of the first fan 3. Taking the communication inlet 211 as an example, Figure 6 The broken line arrow schematically shows that the communication inlet 211 passes through the heat-insulating rear wall 22 along a serpentine path. With this communication inlet 211, the resistance to the gas flowing from the second storage space 102 to the first storage space 101 can be increased. In the absence of additional driving force, the natural convection between the second storage space 102 and the first storage space 101 can be effectively reduced.

[0130] In particular, the at least one communication opening 21 can remain open so that the first storage space 101 and the second storage space 102 are always in fluid communication via the communication opening 21. That is, during operation of the refrigeration appliance, all communication openings 21 connecting the first storage space 101 to the outside thereof remain open.

[0131] The refrigeration appliance may not be provided with a first damper for controlling the opening and closing state of the communication inlet 211. The operation method may particularly include rotating the first fan 3 so as to drive the gas to flow into and / or out of the first storage space 101 via the communication opening 21, and stopping the first fan 3 so as to stop the airflow between the first storage space 101 and the remaining space of the storage space 10. In the case of omitting the first damper, the temperature of the first storage space 101 can still be accurately controlled. By omitting the first damper, the cost of the refrigeration appliance and the complexity of the operation method of the refrigeration appliance can be reduced. The first damper for controlling the opening and closing state of the communication inlet 211 will reduce the volume of the first storage space 101. In order to control the opening and closing state of the first damper, it is also necessary to realize the electrical connection between the first damper and the power supply and / or control device of the refrigeration appliance. The power supply and / or control device are usually arranged outside the first storage space 101 and extended outside the compartment 1. Therefore, by omitting the first damper, the structure can be simplified and the available volume in the storage space 10 can be increased.

[0132] In this article, the "first" and "second" in "first damper" and "second damper" are only used to distinguish the damper (first damper) used to control the opening and closing state of the connecting inlet 211 and the damper (second damper 72) used to control the flow of cooling gas flowing into the storage space 10.

[0133] The serpentine path may in particular have a bending angle of at least 180°. The bending angle may refer to the angle at which the flow direction of the gas is deflected along the serpentine path. Alternatively or additionally, the serpentine path may have at least two bends of more than 180°. Figure 6 As shown, the serpentine path communicating with the inlet 211 may include, for example, a Z-shaped section. The serpentine path communicating with the inlet 211 may also include a U-shaped section.

[0134] When the first fan 3 is turned off, the communication opening 21 extending along the serpentine path can block the gas flow between the first storage space 101 and the second storage space 102. When the first fan 3 is turned on, the gas can flow into and / or out of the first storage space 101 through the communication opening 21. With the serpentine path, the communication opening 21 can block the natural convection between the first storage space 101 and the second storage space 102 on the one hand, and still leave a larger flow cross section on the other hand, so as to allow a larger flow of air to pass when the first fan 3 is turned on.

[0135] For example, any one of the communication openings 21 may have a diameter greater than 250 mm. 2 and / or less than 1000mm 2The minimum flow cross-sectional area of ​​this size range, in combination with the serpentine path, is particularly conducive to accurately controlling the temperature of the first storage space 101 without the first damper for controlling the open and closed state of the communication inlet 211. The communication opening 21 with this size can effectively hinder the natural convection between the first storage space 101 and the second storage space 102, while allowing a larger flow of gas to flow into and out of the first storage space 101 when necessary.

[0136] Back to Figure 2 The communication opening 21 may include a first communication outlet 212 for guiding the gas to flow out from the first storage space 101 .

[0137] The first communication outlet 212 may be located at a side of the first storage space 101 opposite to the second storage space 102. In this embodiment, the first communication outlet 212 is open to the outside at the heat-insulating bottom wall 24.

[0138] The first communication outlet 212 is opened in the opposite direction to the second storage space 102, so that the gas flowing out from the first storage space 101 through the first communication outlet 212 does not flow into the second storage space 102. The gas in the first storage space 101 can flow out through the first communication outlet 212, and Figure 2 As shown by the arrow in FIG. 1 , the air flows backward through the gap between the heat-insulating bottom wall 24 and the bottom wall of the compartment 1 toward the return air port 104 (see FIG. Figure 8 The first return air passage 105 from the first communication outlet 212 to the return air port 104 is located outside the second storage space 102 .

[0139] The operation method includes: turning on the first fan 3 to drive the gas to flow out from the first storage space 101 through the first communication outlet 212, and to leave the storage space 10 through the first return air passage 105 located outside the second storage space 102 and through the return air port 104 of the storage space 10. Therefore, when the first storage space 101 is in the first storage mode, the gas with a higher temperature flowing out through the first communication outlet 212 will not affect the temperature in the second storage space 102.

[0140] The first communication outlet 212 and the communication inlet 211 may be located at opposite sides of the center of the first storage space 101 in the width direction W, the height direction H, and the depth direction D. Thus, the communication inlet 211 and the first communication outlet 212 may be arranged diagonally.

[0141] For example, in terms of the depth direction D, the communication inlet 211 is located at the heat-insulating rear wall 22 , and the first communication outlet 212 is disposed at the front half of the heat-insulating housing 2 opposite to the communication inlet 211 .

[0142] In terms of the height direction H, the communication inlet 211 is offset upward relative to the center of the first storage space 101 , and the first communication outlet 212 is offset downward relative to the center of the first storage space 101 .

[0143] In the width direction W, the communication inlet 211 and the first communication outlet 212 may be located at left and right sides of the center of the first storage space 101 , respectively.

[0144] The communication inlet 211 and the first communication outlet 212 are arranged far from each other, thereby avoiding leaving an area in the first storage space 101 that is difficult to be blown by the gas flowing from the communication inlet 211 to the first communication outlet 212. This helps to make the temperature distribution in the first storage space 101 more uniform.

[0145] Figure 7 A cross-sectional view schematically shows a part of a compartment 1 of a refrigeration appliance according to an exemplary embodiment of the present application, wherein the cross-sectional position can be referred to as Figure 2 The section line BB is shown. Figure 7 As shown, the heat-insulating housing 2 may include a heat-insulating side wall 25 adjacent to the heat-insulating bottom wall 24, and the heat-insulating side wall 25 bounds the first storage space 101 in the width direction W. The first communication outlet 212 may be open to the first storage space 101 at the heat-insulating side wall 25. The first communication outlet 212 may be open to the outside at the heat-insulating bottom wall 24. The gas flowing out of the first storage space 101 through the first communication outlet 212 may flow backward to the return air outlet 104 between the heat-insulating bottom wall 24 and the bottom wall of the compartment 1. Figure 7 As shown by the arrow in , the first communication outlet 212 passes through the heat-insulating housing 2 along a serpentine path. The serpentine path of the first communication outlet 212 may include at least a U-shaped section.

[0146] Figure 8 The compartment 1 and the heat-insulating housing 2 of the refrigeration appliance according to the exemplary embodiment of the present application are schematically shown in an exploded view.

[0147] like Figure 8 As shown, the refrigeration appliance may be provided with an air duct 107 located in the compartment 1 , and the air duct 107 is configured to supply cooling gas to the storage space 10 through at least one air outlet 103 . Figure 8 The air duct 107 is schematically shown by a dotted line in FIG.

[0148] See also Figure 1 The air duct 107 , for example, may be connected to the supply channel 63 , so that the gas cooled by the evaporator 62 may flow into the air duct 107 via the supply channel 63 .

[0149] The heat-insulating housing 2 for separating the first storage space 101 can be arranged in the compartment 1 in a detachable manner.

[0150] The first storage space 101 is not directly connected to the air duct 107. The heat-insulating housing 2 does not need to be connected to the air duct 107. Accordingly, the communication opening 21 of the heat-insulating housing 2 does not need to be accurately arranged to be connected to the air duct 107 in a sealed manner.

[0151] The at least one air outlet 103 for supplying cooling air to the storage space 10 may be arranged above the heat-insulating housing 2. Therefore, the cooling air introduced into the storage space 10 from the air duct 107 flows into the second storage space 102 located above the first storage space 101, and does not flow directly into the first storage space 101.

[0152] When necessary, the first fan 3 can be turned on to introduce cooling gas from the second storage space 102 into the first storage space 101. This helps to achieve the desired temperature in different temperature zones of the storage space 10. The refrigeration appliance does not need to be provided with a duct 107 structure for supplying gas to the first storage space 101. In the operating method of the refrigeration appliance, the temperature control of the first storage space 101 can be independent of the control of the air flow in the duct 107.

[0153] The storage space 10 may be provided with a return air vent 104 so that the gas in the storage space 10 can flow out through the return air vent 104 and flow to the evaporator chamber 61 of the refrigeration appliance. The return air vent 104 may be located directly behind the first storage space 101.

[0154] The return air vent 104 may be arranged to be staggered with the outer opening of the communication inlet 211 in the width direction W. Alternatively or additionally, the return air vent 104 may be arranged to be lower than the outer opening of the communication inlet 211 in the height direction H. The outer opening of the communication inlet 211 may be arranged to be offset rearward relative to the return air vent 104, for example.

[0155] The above arrangement of the return air port 104 helps to optimize the gas flow path in the storage space 10. The airflow from the second storage space 102 to the first storage space 101, the airflow from the first storage space 101 to the return air port 104, and the airflow from the second storage space 102 to the return air port 104 will not interfere with each other. When the communication openings 21 are always kept open, the above airflows will not interfere with each other.

[0156] Combination Figure 2 and Figure 8 It can be seen that the first return air passage 105 from the first communication outlet 212 to the return air port 104 is located outside the second storage space 102. When the first fan 3 is turned on, the gas flowing out from the first storage space 101 through the first communication outlet 212 flows to the return air port 104 through the first return air passage 105 without affecting the second storage space 102.

[0157] Fig. 9 The compartment 1 of the refrigeration appliance according to the exemplary embodiment of the present application is schematically shown in a cross-sectional view, wherein the cross-sectional position can be referred to as Figure 1 Section line CC shown. Fig.10 Schematically shows Fig. 9 A partial enlarged view of the portion framed by the dotted line.

[0158] In this embodiment, the communication opening 21 may include a second communication outlet 213 for guiding the gas to flow out of the first storage space 101. The compartment 1 may be provided with an air inlet 11 for introducing cooling gas into the compartment 1, and the air inlet 11 is provided at the first compartment wall 12 of the compartment 1.

[0159] The air inlet 11 may be connected to the supply channel 63, so that the cooling gas can flow from the supply channel 63 through the air inlet 11 into the compartment 1, such as into the air duct 107 of the compartment 1. The second communication outlet 213 may be disposed adjacent to the air inlet 11 and facing the first compartment wall 12.

[0160] The operation method may include: turning on the first fan 3 to drive the gas to flow out of the first storage space 101 through the second communication outlet 213 , and leave the storage space 10 through the second return air passage 106 located outside the second storage space 102 and through the return air port 104 of the storage space 10 .

[0161] Driven by the first fan 3 , the gas flowing out from the first storage space 101 through the second communication outlet 213 is blown toward the first chamber wall 12 , and flows toward the return air port 104 through the gap between the first chamber wall 12 and the heat insulation housing 2 .

[0162] Thus, condensed water can be prevented from accumulating there. The temperature of the cooling gas introduced through the air inlet 11 is relatively low, so that the first compartment wall 12 has a relatively low temperature at a position adjacent to the air inlet 11. In the case where the second communication outlet 213 is not provided, condensation is likely to occur at the first compartment wall 12 at a position adjacent to the air inlet 11. The generated condensed water may freeze between the first compartment wall 12 and the heat-insulating housing 2.

[0163] like Fig. 9 and Fig.10 As shown, the first compartment wall 12 may limit the compartment 1 in the width direction W. Here, the first compartment wall 12 is, for example, a left side wall. The air inlet 11 may be located at the rear of the first storage space 101 .

[0164] A transition portion 26 may be provided between the heat-insulating rear wall 22 and the heat-insulating side wall 25 of the heat-insulating housing 2 , and the second communication outlet 213 is disposed in the transition portion 26 .

[0165] The transition portion 26 extends obliquely with respect to the width direction W and the depth direction D. The first chamber wall 12 may be provided with an inclined portion opposite to the transition portion 26 .
