Description

air cooled refrigerator

technical field

The invention relates to the technical field of household appliances, in particular to an air-cooled refrigerator.

Background technique

With the development of society and the continuous improvement of people's living standards, people's pace of life is getting faster and faster, so they are more and more willing to buy a lot of food and put it in the refrigerator. The refrigerator has become one of the indispensable household appliances in people's daily life. .

Current refrigerators are generally divided into air-cooled refrigerators and direct-cooled refrigerators according to different cooling methods. Among them, the direct cooling refrigerator uses the natural convection of the air in the refrigerator to cool the food. The evaporator of the direct cooling refrigerator needs to exchange heat with the surrounding air, the air transfers the heat to the evaporator, and the evaporator transfers the cold to the air. After the air absorbs the cold, its temperature drops, its density increases, and it moves downward. The air in the lower part of the refrigerator exchanges heat with the food inside the refrigerator, and the food transfers heat to the air. After the air gets the heat, its temperature rises and its density decreases, and then rises around the evaporator to transfer heat to the evaporator. Cold and hot air circulate through natural convection in this way to achieve the purpose of cooling. The air-cooled refrigerator is provided with an evaporator inside the air duct, and then the cooling generated by the evaporator is delivered to each storage space of the refrigerator through the fan and the air duct. Since the evaporator is not in direct contact with the food in the storage space, the defrosting system can be used to defrost the evaporator by raising the temperature for a short time, without manual defrosting like a direct cooling refrigerator, so it is more and more widely used.

Moreover, various types of refrigerators have more and more functions to meet different needs of users. For example, a refrigerator with an automatic water filling function is connected to the refrigerator through a water pipe, and the water valve is opened to flow into the kettle. The existing kettle is directly placed in the refrigerator, and the user opens the door of the refrigerator at any time to take out the kettle to pour water when taking water. Although this water intake method is simple to implement, it has obvious disadvantages: the water temperature control cannot be realized, and the user cannot determine the water temperature of the water to be taken, which affects the effect and quality of drinking water, and then affects the user experience.

In a specific embodiment, the air-cooled refrigerator 100 further includes: an evaporator configured to provide cold energy to the storage space, and a cooling chamber is defined inside the box body 110, and the evaporator is disposed in the cooling chamber. The air-cooled refrigerator 100 can also include: a refrigerating air duct and a second damper 152, wherein the second damper 152 is arranged on the side opposite to the first damper 151 of the refrigerating space 111, one end of the refrigerating air duct communicates with the cooling chamber, and the other end is divided into two parts. branches, respectively connected to the first damper 151 and the second damper 152.

As shown in FIG. 2 , the first damper 151 is disposed on the right side wall of the refrigerated space 111 , and the second damper 152 is disposed on the right side wall of the refrigerated space 111 . It should be noted that, the above-mentioned specific configurations of the first air door 151 and the second air door 152 are only examples, rather than limiting the present invention. In some other embodiments, the water storage container 130 can also be arranged on the left side of the refrigerated space 111, the first damper 151 is arranged on the left side wall of the refrigerated space 111, and the second damper 152 is arranged on the right side of the refrigerated space 111. side wall. In a word, the first damper 151 and the water storage container 130 are disposed on the same side of the refrigerated space 111 , and the second damper 152 is disposed on the opposite side thereof.

Specifically, the air-cooled refrigerator 100 may include: a refrigeration system, which may be a refrigeration cycle system composed of a compressor, a condenser, a throttling device, an evaporator, and a fan. Wherein the compressor can be installed in the compressor chamber, and the evaporator and fan can be arranged in the cooling room. In another embodiment, the evaporator and the fan can also be arranged in the air supply duct, at this time, the air supply duct can be regarded as a cooling room.

The air-cooled refrigerator 100 of this embodiment can adopt single-system refrigeration, that is, the refrigeration space 111 and the freezing space 112 provide cooling capacity through a set of refrigeration systems. In the case that the freezing space 112 needs supplementary cooling capacity, the air supply duct from the cooling chamber to the freezing space 112 may be connected. When the refrigerated space 111 needs to supplement cooling capacity, the cooling room can be connected to the air supply air duct of the refrigerated space 111 , that is, the refrigerated air duct.

The cooling capacity provided by the refrigeration system to the refrigerating space 111 and the freezing space 112 is different, so that the temperatures in the refrigerating space 111 and the freezing space 112 are also different. The temperature in the refrigerated space 111 is generally between 2°C and 10°C, preferably 3°C to 8°C. The temperature range within the refrigerated space 112 is typically -22°C to -14°C. The optimal storage temperature for different types of food is not the same, and the suitable storage space for storage is also different. For example, fruits and vegetables are suitable for storage in the refrigerated space 111 , and meat food is suitable for storage in the freezing space 112 .

In a preferred embodiment, as shown in FIG. 2 , the air-cooled refrigerator 100 may further include: a heat insulating shell 160 disposed outside the water storage container 130 , and the heat insulating shell 160 is provided with an insulating door 161 , configured to insulate the heat generated by the heater 140 when turned off. When the insulation door 161 is closed, the heat insulation housing 160 can effectively insulate the heat generated when the heater 140 is turned on, preventing the heat from affecting the temperature of other areas of the refrigerated space 111, and ensuring the storage effect of the ingredients in the refrigerated space 111.

It should be noted that, the heat insulation shell 160 and the side wall of the refrigerated space 111 jointly define a space in which the water storage container 130 is placed. Except that the side wall of the refrigerated space 111 is surrounded by foam, the heat insulation shell 160 can be wrapped by a sealing material, which can ensure that when the insulation door 161 is closed, the space where the water storage container 130 is located is a closed space, and can effectively isolate the outside refrigerated space 111 other areas.

In a specific embodiment, the air-cooled refrigerator 100 may further include: a DC motor configured to control the opening and closing state of the insulating door 161 . More specifically, the DC motor can be a common H-bridge forward and reverse DC motor, which can effectively control the opening and closing states of the insulating door 161 . Moreover, in a specific embodiment, the capacity of the water storage container 130 may be 1.5L, and the heater 140 is a 12W DC heating wire. It should be noted that the specific numerical values of the above-mentioned parameters are only examples, rather than limiting the present invention. In some other embodiments, other values may be set according to actual conditions, for example, the capacity of the water storage container 130 may be set according to specific space requirements and drinking water requirements.

In the air-cooled refrigerator 100 of this embodiment, since one end of the refrigerating air duct is connected to the cooling chamber, the other end is divided into two branches, which are respectively connected to the first damper 151 and the second damper 152 . Therefore, no matter whether the first damper 151 is opened or the second damper 152 is opened, the cold generated by the cooling chamber can be transferred to the refrigerated space 111 to ensure that the temperature of the refrigerated space 111 meets the storage requirements.

It should be noted that when the first damper 151 is opened, it is also necessary to ensure that the insulation door 161 is also in an open state, so as to ensure that the cooling energy is blown out from the first damper 151 and delivered to other areas of the refrigerated space 111 through the water storage container 130 . Otherwise, if the first damper 151 is opened and the insulation door 161 is closed, the cold blown from the first damper 151 can only be delivered to the inner space of the heat insulation housing 160 and cannot be delivered to other areas of the refrigerated space 111 . In addition, when cooling the water storage container 130, since the cold wind is blown from the first air door 151 through the water storage container 130 to other areas of the external refrigerated space 111, the temperature of the drinking water inside the water storage container 130 will be earlier than that of the cold air. The temperature of other regions of the refrigerated space 111 is cooled.

As shown in Figure 2, the air-cooled refrigerator 100 can also include: a water inlet pipeline, one end of which is connected to an external water source, and the other end is located above the water inlet of the water storage container 130, and a water valve 170 is arranged on the water inlet pipeline, configured to When opened, the drinking water from the external water source flows to the storage container through the water inlet pipeline. In a specific embodiment, as shown in FIG. 2 , the water valve 170 can be arranged above the water inlet of the water storage container 130 , that is, the water valve 170 can be arranged at the other end of the water inlet pipeline away from the external water source.

In a preferred embodiment, the external water source may be a tap water source, and a filtering device may also be provided in the water inlet pipeline to filter the tap water so that it becomes drinking water that can be imported. In another preferred embodiment, the external water source may be a drinking water source, so that the drinking water that flows into the water storage container 130 is directly available for drinking without filtering.

In a specific embodiment, a temperature sensor is disposed inside the water storage container 130 , configured to detect the actual temperature of the drinking water inside the water storage container 130 . In this way, the real-time temperature of the drinking water inside the water storage container 130 can be known timely and accurately. A water level sensor may also be provided inside the water storage container 130 , so that the actual water level of the drinking water inside the water storage container 130 can be accurately obtained. When the actual water level reaches the water level threshold, the water valve 170 can be closed in time to avoid water overflow and affect the storage environment and use safety of the refrigerated space 111 .

In a preferred embodiment, the door body 120 may be provided with a display device 121 configured to obtain a user's trigger operation to determine the set temperature range of the drinking water inside the water storage container 130 . The user can set the required water temperature through the display device 121, and the display device 121 can display an indicator icon. When the actual temperature reaches the set temperature range, the indicator icon can light up, effectively reminding the user to take out drinking water.

In order to avoid the heating and cooling process of the water storage container 130 from affecting the original storage of the cold storage space 111, the start-stop temperature of the water storage container 130 is within the range of +10°C to -3°C of the current start-stop temperature of the cold storage space 111 , and ensure that the shutdown temperature of the water storage container 130 is higher than 0°C. For example, if the start-up temperature of the refrigerated space 111 is 8°C and the turn-off temperature is 6°C, the start-up temperature of the water storage container 130 is 18°C and the turn-off temperature is 3°C. When the user sets the temperature range from 18° C. to 3° C. through the display device 121 , the user's needs can be met, and the temperature can be heated or cooled according to the actual temperature of the drinking water. However, if the temperature range set by the user through the display device 121 is not 18° C. to 3° C., the setting cannot be made, and the display device 121 can output a prompt message to remind the user that the set temperature range cannot be realized.

Some control methods applicable to the air-cooled refrigerator 100 of this embodiment will be introduced below, specifically, the temperature of drinking water inside the water storage container 130 can be controlled. By obtaining the set temperature range of the drinking water inside the water storage container 130; detecting the actual temperature of the drinking water inside the water storage container 130; judging whether the actual temperature is in the set temperature range, and when the result is no, according to the actual temperature and The set temperature range determines the state of the heater 140 and the first damper 151 , and controls the heater 140 and the first damper 151 to act according to the determined state.

Specifically, the user's trigger operation can be obtained through the display device 121 provided on the door body 120 to determine the set temperature range. For example, the user may input 5° C. to 10° C. as the set temperature range through the display device 121 , indicating that the user needs drinking water in this temperature range. In a special embodiment, the user can input a single value, that is, the set temperature range is a single value. This situation can also be realized, indicating that the user needs drinking water at exactly that temperature.

A temperature sensor may be provided inside the water storage container 130 , so the actual temperature of the drinking water inside the water storage container 130 can be detected by using the temperature sensor. Determine whether the actual temperature is within the set temperature range. If the result is no, it means that the actual temperature of the current drinking water is not within the set temperature range desired by the user, and it needs to be heated or cooled to reach the set temperature range. Meet the needs of users. Therefore, it is possible to perform: determine the state of the heater 140 and the first damper 151 according to the actual temperature and the set temperature range, and control the heater 140 and the first damper 151 to act according to the determined state. According to the actual temperature and the set temperature range, it can be determined whether the drinking water needs to be warmed up or down, and then the states of the heater 140 and the first damper 151 can be determined.

The specific steps of determining the state of the heater 140 and the first damper 151 according to the actual temperature and the set temperature range may include: judging whether the actual temperature is greater than the maximum value in the set temperature range; and if so, controlling the opening of the first damper 151, controlling The heater 140 is turned off, if not, it is determined that the actual temperature is lower than the minimum value in the set temperature range, the heater 140 is controlled to be turned on, and the first damper 151 is controlled to be closed.

Moreover, in a preferred embodiment, the step of controlling the opening of the first damper 151 and controlling the closing of the heater 140 also includes: controlling the closing of the second damper 152 and controlling the opening of the insulation door 161; controlling the opening of the heater 140, The step of controlling the first damper 151 to close also includes: controlling the insulation door 161 to close, and controlling the second damper 152 to act according to the actual temperature of the refrigerated space 111 .

That is to say, if the actual temperature is greater than the maximum value in the set temperature range, it is determined that the drinking water needs to be cooled, the first damper 151 is controlled to be opened, the heater 140 is controlled to be closed, the second damper 152 is controlled to be closed, and the insulating door 161 is controlled to be opened. At this time, the first damper 151 is opened, and the insulation door 161 is opened. The cold air sent from the cold air duct can be blown out through the first damper 151 and the insulation door 161 in turn, and sent to other areas of the refrigerated space 111 to meet normal storage requirements. Since the first damper 151 can realize air supply, the second damper 152 is closed to avoid excessive cooling and affect the temperature of the refrigerated space 111 . Moreover, since the temperature of the drinking water is lowered, the heater 140 does not need to be turned on, so the heater 140 is controlled to be turned off.

If the actual temperature is less than the minimum value in the set temperature range, it is determined that the temperature of the drinking water needs to be raised. At this time, the heater 140 is controlled to be turned on, the first air door 151 is controlled to be closed, the insulating door 161 is controlled to be closed, and the second air door 152 is controlled according to the cold storage space 111. The actual temperature action. The heater 140 is turned on to heat the water storage container 130, and the first air door 151 and the insulating door 161 are closed, so that the space where the water storage container 130 is located is a closed space, preventing the heat generated by the heater 140 from being conducted to other areas of the refrigerated space 111, affecting storage effect. Moreover, at this time, the second damper 152 operates according to the actual temperature of the refrigerated space 111 . That is to say, the second damper 152 works according to the normal on-off temperature of the refrigerated space 111. When the temperature of the refrigerated space 111 reaches the start-up temperature, the second damper 152 is opened, and when the temperature of the refrigerated space 111 reaches the shutdown temperature, the second damper 152 is opened. 152 off.

The temperature of the refrigerated space 111 can be detected by a compartment temperature sensor installed inside the refrigerated space 111, and the compartment temperature sensor can be set on the back side of the refrigerated space 111, and is close to the second damper 152 and far away from the first damper 151, so as to ensure Test results are not affected by heating or cooling of drinking water.

What needs to be explained here is that no matter whether the first damper 151 is opened or the second damper 152 is opened, the compressor and the blower are also turned on at the same time, because the compressor and the blower start to work synchronously, so that the evaporator can generate cooling capacity, and the blower can The cold energy can be better sent to the refrigerated space 111 through the first damper 151 or the second damper 152 . In a preferred embodiment, the first damper 151 and the second damper 152 may be of the same type, that is, the air supply effect of the two is the same. In this way, the normal storage effect of the refrigerated space 111 can be ensured while realizing precise temperature control of the drinking water.

When the actual temperature is within the set temperature range, that is, the actual temperature of the drinking water is within the set temperature range desired by the user, and there is no need to heat it up or cool it down. At this time, the heater 140 can be controlled to turn off, and the first The damper 151 is closed, the insulating door 161 is controlled to be closed, and the display device 121 is controlled to output prompt information to remind the user to take out the water storage container 130 for drinking. The actual temperature is within the set temperature range, indicating that the drinking water can be directly taken out for reference without adjusting the temperature of the drinking water. Therefore, the control heater 140 is turned off without heating it. Control the first damper 151 to close, control the insulation door 161 to close, so that the refrigerated space 111 is not affected by the space where the water storage container 130 is located, and there is no need to open the first damper 151 and the insulation door 161 at this time. At this time, the second damper 152 can operate according to the actual temperature of the refrigerated space 111 as usual. When the display device 121 outputs the prompt information, the user can be promptly and intuitively reminded that the user can directly take out the water storage container 130 for drinking.

In a preferred embodiment, regardless of whether the drinking water reaches the set temperature range after heating or cooling down, or the drinking water is already in the set temperature range, the specific process for the user to take out the water storage container 130 may be: open the refrigerated space 111 After the door body 121, the insulation door 161 is automatically opened, and the user can take out the water storage container 130 through the opened insulation door 161, which effectively improves the intelligence level and greatly improves the user experience.

Because as described above, the air-cooled refrigerator 100 can also include: a water inlet pipeline, one end of which is connected to an external water source, and the other end is located above the water inlet of the water storage container 130, and a water valve 170 is arranged on the water inlet pipeline. Before the step of obtaining the set temperature range of drinking water inside the water storage container 130, it also includes: detecting the actual state of the water storage container 130; judging whether the actual state meets the preset standard; and if so, controlling the water valve 170 to open, so that Potable water from an external water source flows through the water supply line to the storage container. The preset standard is: the water storage container 130 is placed on the base 180 and the actual water level of the drinking water inside is lower than the water level threshold.

That is to say, first check whether the water storage container 130 is placed on the base 180, and whether the actual water level of the drinking water inside is lower than the water level threshold, and the water valve 170 is controlled to open only when the above conditions are met. The water level threshold may be the highest water storage level of the water storage container 130, beyond which there may be a risk of overflow. Because if the water storage container 130 is not placed on the base 180 or the actual water level of the drinking water is equal to or higher than the water level threshold, after the water valve 170 is opened, the drinking water may directly flow to the heater 140 and the base 180, or even to the refrigerated space 111. Other areas affect normal storage and use safety. A water level sensor may be provided inside the water storage container 130 to detect the actual water level. If the actual state of the water storage container 130 does not meet the preset standard, that is, the water storage container 130 is not placed on the base 180, or the actual water level of the drinking water inside is equal to or higher than the water level threshold, then the control water valve 170 remains closed.

In a preferred embodiment, after the step of controlling the opening of the water valve 170, it also includes: timing the opening time of the water valve 170; judging whether the opening time is greater than or equal to a time threshold; and if not, controlling the water valve 170 to remain open state until the actual water level reaches the water level threshold, and the control water valve 170 is closed. If the opening time is greater than or equal to the time threshold, the control water valve 170 may be forced to close. Setting the time threshold can be seen as a protective measure to avoid the failure of the water level sensor. Because if the water level sensor fails, the actual water level cannot be accurately detected, which may cause the water valve 170 to be opened for a long time, and the drinking water overflows. This protective measure further ensures the storage effect and safe use of the refrigerated space 111 .

In addition, it should be emphasized that in order to avoid the heating and cooling process of the water storage container 130 from affecting the original storage of the cold storage space 111, the start-stop temperature of the water storage container 130 is +10°C of the current start-stop temperature of the cold storage space 111 to -3°C, and ensure that the shutdown temperature of the water storage container 130 is higher than 0°C. For example, if the start-up temperature of the refrigerated space 111 is 8°C and the turn-off temperature is 6°C, the start-up temperature of the water storage container 130 is 18°C and the turn-off temperature is 3°C. When the user sets the temperature range from 18° C. to 3° C. through the display device 121 , the user's needs can be met, and the temperature can be heated or cooled according to the actual temperature of the drinking water. However, if the temperature range set by the user through the display device 121 is not 18° C. to 3° C., the setting cannot be made, and the display device 121 can output a prompt message to remind the user that the set temperature range cannot be realized.

In short, in the air-cooled refrigerator 100 of this embodiment, the heater 140 is configured to heat the water storage container 130 when turned on, so that the temperature of the drinking water inside the water storage container 130 increases; the first damper 151 is configured to When the water storage container 130 is opened, the temperature of the water storage container 130 is lowered so that the temperature of the drinking water inside the water storage container 130 is reduced. The temperature of the drinking water inside the container 130 is controlled, which reduces the occupied space and saves production costs; the temperature of the drinking water inside the water storage container 130 can be raised or lowered to fully meet the different drinking water needs of users.

Further, in the air-cooled refrigerator 100 of this embodiment, the door body 120 is provided with a display device 121 configured to obtain a user's trigger operation to determine the set temperature range of drinking water inside the water storage container 130; the water storage container 130 is provided with a temperature sensor inside, which is configured to detect the actual temperature of the drinking water inside the water storage container 130, and the respective states of the first damper 151 and the heater 140 can be determined according to the set temperature range and the actual temperature, so that the actual temperature enters the set temperature. The fixed temperature range can accurately control the temperature of drinking water according to the needs of users, and improve the user experience.
