DETAILED DESCRIPTION OF THE EMBODIMENTS

[0046] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0047] In some technologies, the refrigerator mainly removes the odor gas inside the refrigerator through a deodorization module. However, the deodorization module can only function when the refrigeration air duct is started, resulting in the inability to remove the odor gas in time and affecting the user experience. To solve this technical problem, this application provides a deodorizing refrigerator and a control method. The following is an explanation of the deodorizing refrigerator and the control method:

[0048] The refrigerator, as an indispensable household appliance in modern family life, has long been integrated into all aspects of daily life. It undertakes the important mission of food preservation and brings great convenience to life. Whether it is fresh fruits and vegetables, meat and seafood, or various leftovers, the refrigerator can extend their freshness period, allowing people to taste delicious food at any time. However, during the use of the refrigerator, a troublesome problem gradually emerges. When the refrigerator door is closed for a long time, the internal space is relatively enclosed, the air circulation is poor, and various unpleasant odor gases will be generated in the compartment. These odor gases have a wide range of sources. They may be the odors emitted by the food itself, the stench generated during the food spoilage process, or the special odors released by the growth of bacteria. Since they cannot be dissipated in time, these odor gases accumulate continuously in the refrigerator, not only causing the food in the refrigerator to deteriorate faster, but also providing a breeding ground for the growth and reproduction of bacteria, greatly affecting the food preservation effect, and thus reducing the user experience.

[0049] To address the problem of odor gas inside the refrigerator, most refrigerators on the market currently use a deodorization module to remove these odors. The deodorization module is used to purify the air inside the refrigerator, and it mainly functions through adsorption and decomposition. Among them, common deodorization modules contain substances such as activated carbon and catalysts. Activated carbon has a huge specific surface area and a rich microporous structure, which can effectively adsorb the odor gas molecules inside the refrigerator. The catalyst can promote the chemical reaction of the odor gas molecules and decompose them into harmless substances. When the refrigerator refrigeration air duct starts, it will drive the gas and odor inside the refrigerator to flow to the position where the deodorization module is located. During this process, the odor gas comes into full contact with the deodorization module, and thus is adsorbed or decomposed, ultimately achieving the effect of removing the odor gas inside the refrigerator.

[0050] However, the above-mentioned odor removal method is not perfect and has certain limitations. For activated carbon, although it has strong adsorption ability, its adsorption capacity is limited. As the usage time increases, the activated carbon will gradually reach the adsorption saturation state. Once saturated, it can no longer adsorb more odor gases, and at this time, the user needs to replace the new activated carbon in time. For the catalyst, performance attenuation and other phenomena will also occur during long-term use. The activity of the catalyst will gradually decrease with the increase in the number of uses and the passage of time, resulting in a decrease in its ability to decompose odor gases. Moreover, the odor removal module can only function when the refrigeration air duct is started. Currently, most refrigerators adopt variable frequency technology, which can automatically adjust the operating frequency of the refrigeration air duct according to the temperature and load conditions inside the refrigerator to achieve the purpose of energy saving. But this also means that the refrigeration air duct cannot operate continuously. It will enter the intermittent operation state after reaching the set temperature. During the period when the refrigeration air duct stops operating, the odor gases inside the refrigerator cannot be processed in time and will continue to accumulate inside the refrigerator, thus affecting the removal effect of the odor gases and ultimately affecting the user experience. For example, when the user opens the refrigerator door, they may smell a pungent odor, which reduces the user experience.

[0051] As Figure 1 shown, it is a schematic structural diagram of the odor removal refrigerator in this application.

[0052] The first aspect of this application provides an odor removal refrigerator, including:

[0053] A cabinet 1, in which a refrigerating chamber 11 and a freezing chamber 12 are arranged; wherein, a variable temperature chamber may also be arranged in the cabinet 1, and the numbers of the refrigerating chamber 11, the freezing chamber 12, and the variable temperature chamber are not limited herein.

[0054] A first refrigeration component 2, which is arranged in the refrigerating chamber 11; the first refrigeration component 2 is used for refrigerating the refrigerating chamber 11.

[0055] A second refrigeration component 3, which is arranged in the freezing chamber 12, and the second refrigeration component 3 is communicated with the refrigerating chamber 11; the second refrigeration component 3 is used for refrigerating the freezing chamber 12. Among them, the first refrigeration component 2 and the second refrigeration component 3 are connected to the refrigeration equipment in the refrigerator.

[0056] In some embodiments, the refrigeration equipment may include at least one of a compressor, a condenser, a capillary tube, and an evaporator.

[0057] Exemplarily, the main function of the compressor is to increase the pressure and temperature of the refrigerant vapor, so as to establish a necessary pressure difference in the refrigeration system and promote the refrigerant to circulate in the refrigeration system.

[0058] Exemplarily, the main function of the condenser is to release heat from the high-temperature and high-pressure refrigerant vapor and condense it into a liquid. During the above process, the refrigerant vapor dissipates a large amount of heat to the outside of the refrigeration device 100.

[0059] Exemplarily, the main function of the capillary tube is to restrict the liquid flow rate of the refrigerant and control the pressure difference between the condenser and the evaporator through its flow resistance.

[0060] Exemplarily, the main function of the evaporator is to quickly boil and evaporate the liquid refrigerant under low-temperature and low-pressure conditions, thereby absorbing the heat inside the box body 1 and reducing the temperature inside the box body 1.

[0061] The second refrigeration assembly 3 includes:

[0062] An exhaust duct 31, an air inlet end 311 of the exhaust duct 31 is communicated with the refrigerating chamber 11, an electric valve 32 and an exhaust fan 33 are arranged on one side of the exhaust duct 31 close to the air inlet end 311, and the exhaust fan 33 is arranged on a side of the electric valve 32 away from the air inlet end 311; an odor purification device 4 is arranged on one side of the exhaust duct 31 away from the air inlet end 311; the exhaust duct 31 is used for absorbing the gas in the refrigerating chamber 11, and by opening the electric valve 32 and operating the exhaust fan 33, the gas in the refrigerating chamber 11 can be pumped into the exhaust duct 31, so that the odor gas in the refrigerating chamber 11 is purified by the odor purification device 4 to remove the odor gas in the refrigerating chamber 11.

[0063] A control module 5, the control module 5 is electrically connected to the first refrigeration assembly 2, the electric valve 32, and the exhaust fan 33; the control module 5 is configured to:

[0064] Determine the opening state of the door body 111. If the door body 111 is in an open state, control the first refrigeration assembly 2 to stop operating, and open the electric valve 32 and the exhaust fan 33. The door body 111 is the door body 111 of the refrigerating chamber 11.

[0065] This application proposes an odor-removing refrigerator, aiming to solve the technical problem that users can smell odor gas when opening the refrigerator door. Specifically, when the user opens the refrigerator door 111, the door opening action will serve as a trigger signal, and immediately send a purification instruction to the control module 5 through the built-in sensor system. The control module 5, as the core processing unit of the entire odor-removing system, adopts advanced microprocessor technology and has the ability of real-time response and precise control. After receiving the purification instruction, the control module 5 will immediately execute the preset purification program. First, it stops the operation of the first refrigeration component 2 through a control instruction, avoiding the problem of odor gas diffusion caused by continuous air supply. Currently, when the refrigerator door is opened, the continuous output of cold air often pushes the odor gas in the refrigerator compartment towards the user's face, causing a bad experience. By pausing the operation of the first refrigeration component 2, the diffusion path of the odor gas is effectively blocked.

[0066] After completing the shutdown control of the first refrigeration component 2, the control module 5 will start a dual-channel linkage purification mechanism: on the one hand, it opens the electric valve 32 through a drive circuit, and on the other hand, it synchronously starts the exhaust fan 33. The opening action of the electric valve 32 precisely controls the conduction state of the exhaust duct to ensure the singleness of the gas flow direction; while the exhaust fan 33 adopts a high-performance and low-noise setting, which can generate sufficient negative pressure suction while maintaining quiet operation. The two work together to form a directional air flow channel, sucking the mixed gas in the refrigerator compartment 11 into the exhaust duct 31 at a stable flow rate. The exhaust duct 31, as a gas transmission channel, conveys the odor gas to the odor purification device 4 connected to the end of the duct to purify the odor gas.

[0067] In this embodiment, the first refrigeration component 2 includes:

[0068] A refrigeration air duct 21, which is arranged in the refrigerator compartment 11, and several air outlets 211 are arranged on the refrigeration air duct 21; a refrigeration fan 22 is arranged in the refrigeration air duct 21. One end of the refrigeration air duct 21 is communicated with the refrigeration equipment, so as to convey cold air into the refrigerator compartment 11.

[0069] In this embodiment, the exhaust fan 33 is provided with a first gear and a second gear; the operating power of the exhaust fan 33 corresponding to the first gear is less than the operating power of the exhaust fan 33 corresponding to the second gear. When the exhaust fan 33 is in the first gear, the rotation speed of the exhaust fan 33 is relatively small, which can meet the refrigeration requirements of the refrigerator; when the exhaust fan 33 is in the second gear, the rotation speed of the exhaust fan 33 is relatively large, and it can quickly pump the gas in the refrigerator compartment 11 into the odor purification device 4 of the exhaust duct 31 for purification.

[0070] The control module 5 is further configured to:

[0071] If the exhaust fan 33 is in the on state and the door body 111 is in the closed state, control the exhaust fan 33 to operate at the first gear; if the exhaust fan 33 is in the on state and the door body 111 is in the open state, control the exhaust fan 33 to operate at the second gear.

[0072] It can be understood that the exhaust fan 33 can automatically adjust the operation mode of the exhaust fan 33 according to the opening and closing state of the refrigerator door body, so as to continuously and efficiently purify the odor gas in the refrigerating chamber 11 while ensuring the basic refrigeration function of the refrigerator. When the refrigerator door body 111 is in the closed state, a relatively closed space is formed inside the refrigerator. At this time, the exhaust fan 33 does not need to operate at a high power, but operates at a relatively small power in the first gear according to the pre-set energy-saving mode. On the one hand, it can meet the basic requirements of gas circulation during the normal refrigeration process of the refrigerator, ensure the uniform distribution of cold air in the refrigerating chamber, maintain a stable low-temperature environment, and ensure the freshness preservation effect of food; on the other hand, the lower fan power can effectively reduce energy consumption and reduce unnecessary power loss, which conforms to the design concept of energy conservation and environmental protection.

[0073] Although the exhaust fan 33 can still continuously play the role of odor purification in the first gear. It will suck the odor gas slowly released in the refrigerating chamber 11 into the exhaust duct 31 at a relatively gentle but stable air flow rate. These odor gases will then be transported through the exhaust duct 31 to the odor purification device 4 for purification. This continuous low-power purification mode can effectively control the odor problem in the refrigerating chamber for a long time without affecting the normal use of the refrigerator. However, when the user opens the refrigerator door body 111, the odor gas in the refrigerating chamber 11 diffuses outwards, and the user is likely to immediately smell the odor, which will greatly reduce the user experience.

[0074] Specifically, after detecting the door opening signal, the control module 5 will send a power increase command to the exhaust fan 33, so that it quickly switches from the first gear to the second gear. The exhaust fan 33 in the second gear operates at a higher speed and stronger suction, and can form a strong negative pressure air flow in a short time to quickly evacuate the gas in the refrigerating chamber 11. This high-power operation mode greatly accelerates the gas evacuation rate, so that the odor gas can be more quickly transported to the exhaust duct 31 and enter the odor purification device 4 for purification.

[0075] It is worth noting that a gas concentration sensor is provided in the box body 1. When the gas concentration in the refrigerating chamber 11 is greater than the preset concentration value, the electric valve 32 and the exhaust fan 33 are turned on. If the door body 111 is not opened, it is only necessary to control the exhaust fan 33 to operate at the first gear.

[0076] In this embodiment, the second refrigeration assembly 3 further includes: a compressor compartment 34, and an air outlet end 312 of the exhaust air duct 31 is communicated with the compressor compartment 34. The compressor compartment 34 is used to place a compressor, and the main function of the compressor is to lift low-pressure gas to high-pressure gas, suck in low-temperature and low-pressure refrigerant gas from the exhaust air duct 31, and convert it into high-temperature and high-pressure refrigerant gas.

[0077] In this embodiment, the deodorizing refrigerator further includes:

[0078] A refrigerating chamber door switch 6, which is arranged in the refrigerating chamber 11; the refrigerating chamber door switch 6 is electrically connected to the control module 5, and the control module 5 is further configured to: determine whether the refrigerating chamber door switch 6 is closed. If so, the door body 111 is in a closed state; if not, the door body 111 is in an open state.

[0079] In this embodiment, the control module 5 of the deodorizing refrigerator is further configured to:

[0080] If the door body 111 is changed from the open state to the closed state, control the electric valve 32 and the exhaust air fan 33 to close, and turn on the first refrigeration assembly 2. When the user closes the door body 111, there is no need to perform the odor gas purification work. At this time, because the purification work has just been completed, the concentration of the odor gas in the refrigerating chamber 11 basically does not reach the concentration requirement of the purification function. Therefore, control the electric valve 32 and the exhaust air fan 33 to close, and turn on the first refrigeration assembly 2 to normally refrigerate the refrigerating chamber 11.

[0081] In this embodiment, the control module 5 is further configured to:

[0082] If the door body 111 is changed from the open state to the closed state, control the electric valve 32 and the exhaust air fan 33 to close after a preset time. By controlling the electric valve 32 and the exhaust air fan 33 to close after a preset time, the concentration of the odor gas in the refrigerating chamber 11 is further reduced.

[0083] In this embodiment, the deodorizing refrigerator further includes:

[0084] A temperature sensor 7, which is arranged in the refrigerating chamber 11; the temperature sensor 7 is configured to:

[0085] Obtain the temperature in the refrigerating chamber 11.

[0086] The control module 5 is further configured to:

[0087] If the temperature in the refrigerating chamber 11 is lower than the set temperature, the first refrigeration component 2 is controlled to close. The above is the refrigeration operation of the refrigerating chamber 11. The temperature in the refrigerating chamber 11 is obtained through the temperature sensor 7, so as to control the first refrigeration component 2 to close or open, so that the temperature in the refrigerating chamber 11 is below the preset temperature.

[0088] In this embodiment, the odor purification device 4 includes but is not limited to: an activated carbon adsorption device, a metal catalyst honeycomb ceramic device, an ion generation and release device, and an ozone generation and release device. It should be noted that one or more of the above devices may be included.

[0089] This application provides an odor-removing refrigerator, and the specific implementation is as follows:

[0090] When the control module 5 detects that the user opens the refrigerator door body 111, the control module 5 controls the refrigeration fan 22 in the refrigerating air duct 21 to stop running, the refrigeration inside the refrigerating chamber 11 stops, and the fresh air outside enters the refrigerating chamber 1 after the refrigerator door body 111 is opened. At the same time, the electric valve 32 and the exhaust fan 33 are started, and the original odor gas in the refrigerating chamber 11 is discharged through the exhaust duct 31. The odor gas in the refrigerating chamber 11 enters the exhaust duct 31 from the air outlet end 312, and the odor is decomposed by the odor purification device 4 in the exhaust duct 31, and then discharged to the compressor compartment 34 through the air outlet end 312, so as to realize the fresh air replacement of the air inside the refrigerator.

[0091] After the refrigerator door body 111 is opened, if it is detected that the refrigerator door body 111 is closed, the electric valve 32 and the exhaust fan 33 are controlled to run for 5 to 10 minutes and then automatically close, and then the refrigeration fan 22 in the refrigerating air duct 21 is started to refrigerate the refrigerating chamber 11. When the temperature in the refrigerating chamber 11 returns to the set temperature, the refrigeration fan 2 is controlled to stop running, so that the temperature in the refrigerating chamber 11 reaches the set temperature; if it is not detected that the refrigerator door body 111 is closed, the electric valve 32 and the exhaust fan 33 are controlled to continue running.

[0092] The second aspect of this application provides a control method for an odor-removing refrigerator, which is applied to an odor-removing refrigerator described in any of the above embodiments. The refrigerator is provided with a refrigerating chamber and a freezing chamber, and includes:

[0093] Determine the opening state of the door body. If the door body is in the open state, control the first refrigeration component to stop running, and turn on the electric valve and the exhaust fan;

[0094] Wherein, the first refrigeration component is arranged in the refrigerating chamber;

[0095] The second refrigeration component is arranged in the freezing chamber, and the second refrigeration component is communicated with the refrigerating chamber;

[0096] The second refrigeration component includes:

[0097] An exhaust duct, the air inlet end of the exhaust duct is communicated with the refrigerating chamber, an electric valve and an exhaust fan are arranged on one side of the exhaust duct close to the air inlet end, and the exhaust fan is arranged on the side of the electric valve away from the air inlet end; an odor purification device is arranged on one side of the exhaust duct away from the air inlet end.
