Description

Technical Field

[0001] The utility model relates to a refrigerator. Background Art

[0002] As the market demand for multifunctional storage in refrigerators gradually increases, independent climate control rooms are often added to the cold storage room.

[0003] Figure 3 1 is a perspective rear view schematically showing a conventional refrigerator 3 . Figure 4 Schematically shows a perspective side view of a conventional refrigerator 3. Figure 3 As shown, in the existing refrigerator 3, in order to ensure that air is supplied to the refrigerating chamber 310 and the temperature-changing chamber 320 therein independently, it is necessary to control the opening and closing of the first baffle 330 and the second baffle 340 respectively. The independent air supply to the refrigerating chamber 310 is completed by the following actions: the fan 350 is started, the first baffle 330 is opened and the second baffle 340 is closed, and air is supplied through the first air passages 361, 362, 363 (the first air passages 361, 362, 363 are in Figure 3 The independent air supply of the variable temperature room 320 is completed by the following actions: the fan 350 is started, the first baffle 330 is closed and the second baffle 340 is opened, and air is supplied through the second air path 370 (the second air path 370 is in Figure 3 Indicated by arrows in the figure).

[0004] However, in the above-mentioned existing refrigerator 3, if the independent air supply of the refrigerating chamber 310 and the variable temperature chamber 320 is to be realized, two baffles are required and the two baffles need to be controlled independently, which increases the cost. In addition, the evaporator 380 is shared by the refrigerating chamber 310 and the variable temperature chamber 320, so the temperature range of the variable temperature chamber 320 is limited and the temperature control range is small. Therefore, the problem that follows is how to make the structure of realizing the function of independent air supply of each compartment simpler and expand the temperature control range of the variable temperature chamber. Utility Model Content

[0005] The utility model is completed based on the above-mentioned problem, and its purpose is to provide a refrigerator, which can make the structure of realizing the function of independent air supply to each compartment simpler and expand the temperature control range of the independent compartment.

[0006] One aspect of the utility model provides a refrigerator, comprising: a first compartment set in a refrigerating temperature zone; a second compartment set in a freezing temperature zone; an independent compartment arranged in the first compartment and capable of independently controlling temperature; a first evaporator for cooling the second compartment; an air inlet arranged in a heat insulating layer between the first compartment and the second compartment, for introducing cold air from the first evaporator into the independent compartment; an air return port, for returning the gas flowing through the independent compartment to the first evaporator; and a baffle assembly, comprising a baffle arranged at the air inlet in a manner capable of opening or closing the air inlet, the baffle being controlled to be opened or closed according to the set temperature of the independent compartment and the current temperature in the independent compartment.

[0007] Therefore, the refrigerator of the utility model has an air inlet for introducing cold air from the first evaporator into the independent compartment, and a baffle assembly arranged at the air inlet, so that the first evaporator for cooling the second compartment can also cool the independent compartment, thereby expanding the temperature control range of the independent compartment. In addition, since there is no need to arrange a baffle in the first compartment, the structure for realizing the function of independent air supply to each compartment can be made simpler, thereby reducing the manufacturing cost.

[0008] In addition, the refrigerator of the utility model may also be provided with a return air duct, one end of which is connected to the return air port, and the other end of which is connected to the first evaporator, and the return air duct is covered by the first heat insulating material. With this structure, the gas introduced into the independent compartment can be more reliably led out to the first evaporator. In addition, since the temperature at the evaporator is relatively low and the temperature of the gas led out from the independent compartment is relatively high, it is easy to condense and frost at the return air duct. By covering the return air duct with the first heat insulating material, the above-mentioned problem can be avoided.

[0009] In addition, in the refrigerator of the utility model, the baffle assembly may also include: a second heat insulating material covering the baffle; a sealing material covering the baffle in a manner of sandwiching the second heat insulating material between the baffle and the sealing material, for sealing the air inlet when the baffle is closed; and a heater for heating the baffle. With this structure, when the baffle is closed, the heat exchange between the independent compartment and the first evaporator can be effectively reduced, and the problem of condensation and frosting on the baffle can be prevented.

[0010] In addition, the refrigerator of the utility model can also be separated by a third heat insulating material formed in a plate shape between the first chamber and the independent chamber. Through this structure, the heat exchange between the first chamber and the independent chamber can be effectively reduced to ensure the normal operation of the refrigerator.

[0011] In addition, the refrigerator of the utility model may also have an air inlet duct, one end of which is connected to the air inlet, and the other end of which is connected to the first evaporator. With this structure, the cold air from the first evaporator can be more reliably introduced into the independent compartment, thereby improving the refrigeration efficiency of the independent compartment.

[0012] In addition, the refrigerator of the utility model may also be provided with a fan for introducing gas into the independent compartment via the air inlet. With this structure, the cold air from the first evaporator can be introduced into the independent compartment more reliably, thereby improving the refrigeration efficiency of the independent compartment.

[0013] In addition, in the refrigerator of the present invention, the set temperature of the independent compartment may be between the upper limit value of the set temperature of the first compartment and the lower limit value of the set temperature of the second compartment.

[0014] In addition, the refrigerator of the utility model may also be provided with: a second evaporator for cooling only the space in the first room except the independent room. With this structure, the first room can be cooled by the second evaporator, and the second room and the independent room can be cooled by the first evaporator. Under the premise of ensuring independent air supply to each room, the structure is simpler and the temperature control range of the independent room is expanded.

[0015] In addition, the refrigerator of the utility model can also be observed from the depth direction of the refrigerator, and the distance between the lowest position of the second evaporator in the height direction of the refrigerator and the third heat insulating material in the height direction of the refrigerator is greater than the first distance. Through this structure, it is possible to ensure that there is a relatively large distance between the second evaporator and the third heat insulating material. Since the heat insulation performance of the installation matching area between the first compartment cover plate and the third heat insulating material is relatively poor, by making the second evaporator and the third heat insulating material have a relatively large distance, it is possible to effectively prevent the installation matching area between the first compartment cover plate and the third heat insulating material from being overcooled.

[0016] In addition, the refrigerator of the utility model can also perform the following actions when cooling the independent compartment: the baffle is opened, the fan is turned on, and the first evaporator cools the gas. Through this structure, the cold air from the first evaporator can be reliably introduced into the independent compartment, thereby improving the cooling efficiency of the independent compartment.

[0018] According to the refrigerator of the utility model, the structure for realizing the function of independent air supply in each compartment can be made simpler, and the temperature control range of the independent compartment can be expanded. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In this specification, it should be understood that terms such as “includes,” “comprising,” and “having” refer to the existence of stated features, quantities, steps, operations, elements, parts, or a combination thereof, but do not exclude the existence of one or more other features, quantities, steps, operations, elements, parts, or a combination thereof.

[0030] Figure 1 Schematically shows a perspective rear view of a refrigerator 1 according to the present invention.

[0031] like Figure 1 As shown, the refrigerator 1 includes a first compartment 10 , a second compartment 20 and an independent compartment 30 .

[0032] The first compartment 10 is set in a refrigeration temperature range. The first compartment 10 is, for example, a compartment (refrigeration room) for refrigerating and storing items, and the temperature inside the compartment is usually 1° C. to 10° C., but is not limited thereto and may be in other suitable temperature ranges.

[0033] The second compartment 20 is set in a freezing temperature zone. The second compartment 20 is, for example, a compartment (freezer) for freezing and storing items, and the temperature inside the compartment is usually -23°C to -15°C, but is not limited thereto and may be any other suitable temperature range. In addition, in order to improve the state of freezing and storage, for example, the minimum temperature may be set to any value between -30°C and -23°C.

[0034] The independent chamber 30 is disposed in the first chamber 10. The independent chamber 30 can independently control the temperature.

[0035] like Figure 1 As shown, the first chamber 10 and the independent chamber 30 are separated by a third heat insulating material 120 formed in a plate shape.

[0036] The independent compartment 30 is, for example, a compartment (variable temperature compartment) whose temperature can be switched as needed, for example, it can be switched between the above-mentioned refrigeration temperature zone, freezing temperature zone or other pre-set temperature zones. The set temperature of the independent compartment 30 is between the upper limit of the set temperature of the first compartment 10 and the lower limit of the set temperature of the second compartment 20, but is not limited thereto, and may also be other suitable temperature ranges.

[0037] like Figure 1 As shown, the refrigerator 1 further includes a first evaporator 40 . The first evaporator 40 is used to cool the second compartment 20 .

[0038] The refrigerator 1 further includes an air inlet 50 . The air inlet 50 is disposed in the heat insulating layer 60 between the first compartment 10 and the second compartment 20 . The air inlet 50 introduces cold air from the first evaporator 40 into the independent compartment 30 .

[0039] The refrigerator 1 further includes a return air port 70 . The return air port 70 is disposed in the heat insulating layer 60 between the first compartment 10 and the second compartment 20 . The return air port 70 returns the gas flowing through the independent compartment 30 to the first evaporator 40 .

[0040] The refrigerator 1 further includes a first fan 80 (corresponding to the “fan” in the claims). The first fan 80 is used to introduce air into the independent chamber 30 through the air inlet 50 .

[0041] When viewed from the x direction, the first fan 80 is disposed above the first evaporator 40 in the z direction, that is, the first fan 80 is closer to the positive direction of the z direction relative to the first evaporator 40. However, the present invention is not limited thereto, and the first fan 80 may also be disposed at other suitable positions as long as the requirement of introducing the gas into the independent chamber 30 through the air inlet 50 is met.

[0042] The refrigerator 1 also includes an air inlet duct 90. The air inlet duct 90 is Figure 1 One end of the air inlet 90 is connected to the air inlet 50, and the other end is connected to the first evaporator 40. Specifically, Figure 1 As shown, the other end of the air inlet duct 90 is arranged close to the first fan 80 .

[0043] The refrigerator 1 further includes a return air duct 100 . One end of the return air duct 100 is connected to the return air port 70 , and the other end thereof is connected to the first evaporator 40 .

[0044] The return air duct 100 is covered by the first heat insulating material 110. Since the temperature at the first evaporator 40 is relatively low and the temperature of the gas discharged from the independent compartment 30 is relatively high, frost is easily formed at the return air duct 100. By covering the return air duct 100 with the first heat insulating material 110, the above problem can be avoided.

[0045] Figure 2 Schematically shows a cross-sectional view of a baffle assembly 130 according to the present invention.

[0046] like Figure 1 and Figure 2 As shown, the refrigerator 1 further includes a baffle assembly 130. The baffle assembly 130 includes a baffle 131. The baffle 131 is disposed at the air inlet 50 in a manner that the air inlet 50 can be opened or closed.

[0047] The damper 131 is controlled to be opened and closed according to the set temperature of the independent compartment 30 and the current temperature in the independent compartment 30 .

[0048] like Figure 2 As shown, the baffle assembly 130 further comprises a second heat insulating material 132 . The second heat insulating material 132 covers the baffle 131 .

[0049] The baffle assembly 130 further includes a sealing material 133. The sealing material 133 covers the baffle 131 in a manner that the second heat insulating material 132 is sandwiched between the baffle 131 and the sealing material 133. The sealing material 133 is used to seal the air inlet 50 when the baffle 131 is in a closed state.

[0050] The baffle assembly 130 further includes a heater (not shown) for heating the baffle 131 .

[0051] The current temperature in the independent compartment 30 is detected by, for example, a temperature sensor (not shown).

[0052] For example, when it is detected that the current temperature in the independent compartment 30 is below the set temperature of the independent compartment 30, the damper 131 is closed to stop cooling the independent compartment 30. When it is detected that the current temperature in the independent compartment 30 is greater than the set temperature of the independent compartment 30, the damper 131 is opened to cool the independent compartment 30.

[0053] When cooling the independent compartment 30 , the following actions are performed: the damper 131 is opened, the first fan 80 is turned on, and the first evaporator 40 cools the gas.

[0054] With the above structure, the first evaporator 40 that supplies air to the second compartment 20 can supply air to the independent compartment 30 for cooling, thereby making the structure for realizing the function of independent air supply to each compartment simpler and expanding the temperature control range of the independent compartment 30.

[0055] Refer again Figure 1 The refrigerator 1 further includes a second evaporator 140. The second evaporator 140 is used to cool only the space in the first compartment 10 except the independent compartment 30.

[0056] When viewed from the x direction, the distance between the lowest position of the second evaporator 140 in the z direction and the third thermal insulation material 120 in the z direction is greater than the first distance H (eg Figure 1 The first distance H may be 5 to 10 cm, but is not limited thereto, and may also be other suitable values, as long as the requirement of preventing the installation matching area of ​​the third heat insulating material 120 and the first compartment cover (not shown) from being overcooled can be met.

[0057] The first compartment cover is a cover for forming the first compartment air ducts 161, 162, 163. The first compartment cover is substantially perpendicular to the third heat insulating material 120. The first compartment cover is substantially opposite to the back of the refrigerator 1.

[0058] Through the above structure, it is possible to ensure that there is a relatively large distance between the second evaporator 140 and the third heat insulating material 120, thereby effectively preventing the installation matching area between the first chamber cover plate and the third heat insulating material 120 from being overcooled.

[0059] like Figure 1 As shown, the refrigerator 1 further includes a second fan 150 . The second fan 150 is used to introduce gas from the second evaporator 140 into the first chamber 10 .

[0060] When viewed from the x direction, the second fan 150 is disposed above the second evaporator 140 in the z direction, that is, the second fan 150 is closer to the positive direction of the z direction relative to the second evaporator 140. However, the present invention is not limited thereto, and the second fan 150 may also be disposed at other suitable positions as long as the requirement of introducing the gas from the second evaporator 140 into the first chamber 10 is met.

[0061] The refrigerator 1 further includes first compartment air ducts 161, 162, 163. The first compartment air ducts 161, 162, 163 are arranged Figure 1 One end of the first compartment air duct 161, 162, 163 is connected to the first compartment 10, and the other end is connected to the second evaporator 140. Specifically, Figure 1 As shown, the other end of the first compartment air ducts 161 , 162 , 163 is arranged close to the second fan 150 .

[0062] The number of the first chamber air ducts is not limited to three, and may be one, two, four, etc., for example.

[0063] When the first compartment 10 is refrigerated, the second evaporator 140 cools the gas, the second fan 150 is started, and the gas is introduced into the first compartment 10 through the first compartment air ducts 161, 162, and 163. When the independent compartment 30 is refrigerated, the first evaporator 40 cools the gas, the first fan 80 is started, the baffle 131 is opened, and the gas is introduced into the independent compartment 30 through the air inlet duct 90 and the air inlet 50. Thus, the structure for realizing the function of independent air supply to each compartment can be made simpler, the temperature control range of the independent compartment 30 is expanded, and the installation matching area of ​​the third heat insulating material 120 between the independent compartment 30 and the first compartment 10 and the first compartment cover plate is prevented from being overcooled.

[0064] Although the utility model is specifically described above in conjunction with the accompanying drawings and embodiments, it is to be understood that the above description does not limit the utility model in any form. Those skilled in the art can modify and change the utility model as needed without departing from the essential spirit and scope of the utility model, and these modifications and changes all fall within the scope of the utility model.
