A refrigerating and freezing apparatus and a compartment dividing assembly thereof according to an embodiment of the present invention will be described with reference to fig. 1 to 5. All "lateral" directions refer to the left and right directions indicated in the drawings. Fig. 1 is a schematic structural view of a refrigerating and freezing apparatus according to an embodiment of the present invention; FIG. 2 is a schematic diagram of the construction of the compartment divider assembly 10 according to one embodiment of the present invention; fig. 3 is a schematic bottom structure view of the compartment divider assembly 10 shown in fig. 2, in which the first tuyere 110 and the second tuyere 120 are in a fully opened state; fig. 4 is a schematic bottom structure view of the compartment divider assembly 10 shown in fig. 2, in which the first tuyere 110 and the second tuyere 120 are in a completely closed state.
The embodiment of the invention provides a compartment partition assembly 10 for a refrigerating and freezing device, wherein the compartment partition assembly 10 comprises a partition 100, a first air door 300 and a second air door 400 which are installed on the partition 100, and an air door driving mechanism.
As shown in fig. 1, a partition 100 is provided in a storage compartment 21 of the refrigerating and freezing apparatus to partition the storage compartment 21. For example, the partition 100 shown in fig. 1 divides the storage compartment 21 into two sub-compartments (a first sub-compartment 201 and a second sub-compartment 202, respectively) to improve the usability of the refrigerating and freezing device.
As shown in fig. 2 and 3, the partition 100 is opened at front and rear portions thereof with a first tuyere 110 and a second tuyere 120, respectively. When the compartment separation assembly 10 of the present invention is applied to a refrigeration and freezing apparatus, one of the two sub-compartments continues to be cooled by the cold air source of the storage compartment 21, and the cold air source of the other sub-compartment is controlled by the partition board 100, i.e. one of the first air outlet 110 and the second air outlet 120 is the cold air inlet of the sub-compartment, and the other is the hot air outlet (the cold air is changed into hot air after exchanging heat with the stored objects in the sub-compartment). Thus, the cold air input amount of the sub-compartment can be adjusted by adjusting the flow areas of the first air outlet 110 and the second air outlet 120, and the refrigeration temperature of the sub-compartment can be adjusted. The first damper 300 is used to adjust the flow area of the first tuyere 110, and the second damper 400 is used to adjust the flow area of the second tuyere 120. The damper driving mechanism is configured to drive the first damper 300 and the second damper 400 to synchronously move so as to synchronously adjust the flow areas of the first tuyere 110 and the second tuyere 120 and synchronously increase or synchronously decrease the flow areas of the first tuyere 110 and the second tuyere 120. The first damper 300 and the second damper 400 are preferably disposed on the bottom surface of the partition 100.
In some embodiments, the first damper 300 and the second damper 400 can translationally adjust the flow areas of the first tuyere 110 and the second tuyere 120, respectively, in parallel against the partition 100. As shown in fig. 3, the first damper 300 and the second damper 400 may be flat plate-shaped. Fig. 3 illustrates a state in which the first tuyere 110 and the second tuyere 120 are fully opened. At this time, the first damper 300 is moved forward, so that the area of the first damper 110 covered by the first damper can be changed, and the flow area of the first damper 110 can be changed, and when the first damper 300 moves forward to the state shown in fig. 4, the first damper 110 is completely closed. Similarly, the area of the second air vent 120 covered by the second air vent 400 can be changed by moving the second air vent 400 backward, and the flow area of the second air vent 120 can be changed, so that when the second air vent 400 moves forward to the state shown in fig. 4, the second air vent 120 is completely closed.
The damper drive mechanism further includes at least one rack and pinion mechanism, each having a gear 530, a first rack 510, and a second rack 520. Wherein gear 530 is mounted to bulkhead 100 for fixed rotation (i.e., capable of only rotating about its axis). The first rack 510 is located on the first damper 300 and engaged with the gear 530; the second rack 520 is located on the second damper 400 and is engaged with the gear 530, as shown in fig. 3. In this manner, when one of the first damper 300 and the second damper 400 translates, the other can be simultaneously translated via the rack and pinion mechanism. As shown in fig. 3, when the first damper 300 is pushed forward by an external force, the first rack 510 on the left side drives the gear 530 on the left side to rotate clockwise, and the gear 530 pushes the second rack 520 to move backward, thereby pushing the second damper 400 to move backward.
In some embodiments, the number of rack and pinion mechanisms is preferably two. As shown in fig. 3, the first damper 300 includes a first shielding plate 310 and two first arm plates 320 extending rearward from both lateral ends (i.e., left and right ends) of the first shielding plate 310, respectively. The first shielding plate 310 is used to shield the first tuyere 110. The lateral side of the rear portion of each first arm plate facing the other first arm plate is provided with a first rack 510, as shown in fig. 3, the right side of the first arm plate 320 on the left side is formed with the first rack 510, and the left side of the first arm plate 320 on the right side is formed with the first rack 510. The second damper 400 includes a second shielding plate 410 and a second arm plate 420 extending forward from a widthwise middle portion of the second shielding plate 410. The second shielding plate 410 is used to shield the second tuyere 120. The front portion of the second arm plate 420 is located between the two first arm plates 320, and two lateral sides (i.e., left and right sides) form one second rack 520, respectively, and each gear 530 is located between one first rack 510 and one second rack 520. That is, the first rack 510, the gear 530, and the second rack 520 on the left side together constitute one rack-and-pinion mechanism, and the first rack 510, the gear 530, and the second rack 520 on the right side together constitute the other rack-and-pinion mechanism. The two gear rack structures are arranged, so that the stress of the first air door 300 and the second air door 400 is more uniform, and the translation is more stable.
In some embodiments, the damper drive mechanism further comprises a lead screw nut mechanism 600. The lead screw-nut mechanism 600 includes a lead screw 620 having an external thread and a motor 610. The screw 620 is engaged with the internal thread formed on the first damper 300 or the second damper 400, so as to drive the first damper 300 or the second damper 400 to move horizontally when rotating. The motor 610 is mounted to the partition 100 for driving the lead screw 620 to rotate. According to the embodiment of the invention, the first air door 300 and the second air door 400 are driven to synchronously translate through the screw and nut mechanism 600, the structure is simple, the operation is accurate, and the automatic control is convenient to realize. Of course, other means, such as a linear motor, may be used to drive the translation of the motorized damper 400.
Of course, in some alternative embodiments, a manual method may be used instead of the lead screw and nut mechanism 600, and one of the first damper 300 or the second damper 400 may be pushed and pulled by hand to move the other to translate synchronously.
For example, as shown in fig. 3, a connecting plate 630 is disposed between the two first arm plates 320 of the first damper 300, and the middle of the connecting plate 630 is provided with the aforementioned internal thread, so that the screw 620 is screwed therein.
In some embodiments, two first limiting protrusions 130 extending back and forth are disposed on the partition 100, and the two first arm plates 320 respectively abut against the inner sides of the two first limiting protrusions 130, so that the first damper 300 can only translate back and forth. In addition, the rear end of each first limiting protrusion 130 is bent inwards in the transverse direction to form a bent portion 132, and when the first damper 300 moves backwards to a position of fully opening the first air opening 110, the rear end of each first arm plate 320 abuts against one bent portion 132 to limit that the first damper 300 cannot move backwards any more.
The partition 100 may further include two second limiting protrusions 140 extending forward and backward, and both lateral sides of the second arm plate 420 may abut against inner sides of the two second limiting protrusions 140, respectively, so that the second damper 400 may only translate forward and backward.
In the embodiment of the present invention, the first limiting protrusion 130 and the second limiting protrusion 140 are provided, so that the front and back translation of the first damper 300 and the second damper 400 is more stable.
The invention also provides a refrigerating and freezing device. The refrigerating and freezing device can be a household refrigerator, a commercial refrigerator or a freezer and the like, and can provide cold energy for stored objects by adopting a steam compression refrigeration cycle system, semiconductor refrigeration and other modes.
As shown in fig. 1, the refrigerating and freezing apparatus includes a cabinet 20 defining at least one storage compartment, including a storage compartment 21. The refrigeration freezer further includes the compartment divider assembly 10 of any of the above embodiments. The compartment separation assembly 10 is installed in the storage compartment 21 to separate the storage compartment 21 into a first sub-compartment 201 and a second sub-compartment 202. The partition plate 100 of the compartment partition assembly 10 may be horizontally disposed, and the upper and lower sides of the partition plate 100 are respectively the first sub-compartment 201 and the second sub-compartment 202. It is preferable that the partition board 100 is attachable to a plurality of height positions in the storage compartment 21 (for example, a plurality of slots or protrusions having different heights are provided on both lateral side walls of the storage compartment 21 to support both lateral sides of the partition board 100), so that the volume of the first sub-compartment 201 is reduced and the volume of the second sub-compartment 202 is increased by moving the partition board 100 upward, or the volume of the first sub-compartment 201 is increased and the volume of the second sub-compartment 202 is reduced by moving the partition board 100 downward. In short, the volume ratio of the first sub-chamber 201 and the second sub-chamber 202 is adjustable, so as to meet the use requirements of users.
In the embodiment of the present invention, the first sub-compartment 201 can continue to use the original cold air source of the storage compartment 21 for refrigeration, so that the cold air source of the second sub-compartment 202 is controlled by the partition 100. That is, the refrigerating and freezing device is configured to make the cold air enter the second sub-compartment 202 through the second air opening 120, exchange heat with the stored substance therein, and flow to the first sub-compartment 201 through the first air opening 110. That is, the second air outlet 120 is a cold air inlet of the second sub-chamber 202, and the first air outlet 110 is a hot air outlet of the second sub-chamber 202. Therefore, the cold air input quantity of the second sub-compartment 202 can be adjusted by changing the flow areas of the first air opening 110 and the second air opening 120, and the refrigeration temperature can be adjusted.
Specifically, as shown in fig. 1, the refrigerating and freezing device may include a cooling compartment 22 for generating cool air and an air duct 23. A refrigeration chiller, such as a vapor compression refrigeration cycle refrigeration system, has an evaporator 40 disposed within a cooling chamber 22. The air duct 23 has an air inlet 203 communicating with the cooling compartment 22 and a plurality of air outlets 204, 205 supplying air to the storage compartment 21 to introduce cold air from the cooling compartment 22 into the first sub-compartment 201 and the second sub-compartment 202. A fan 30 may also be provided downstream of the evaporator 40 to accelerate the cold gas flow rate. The air outlet 204 communicating with the first sub-chamber 201 is located upstream of the air duct 23, and the air outlet 205 communicating with the second sub-chamber 202 is located downstream of the air duct 23. Also, an air outlet may be provided at the upper side of each shelf 208. As shown in fig. 1, the cooling chamber 22 may be located at an upper side of the storage compartment 21, and the cool air in the air duct 23 flows downward from above, and an upper portion of the air duct 23 is an upstream side, and a lower portion thereof is a downstream side. The rear end of the partition board 100 extends into the air duct 23 to make the second air opening 120 located in the air duct 23, and when the second air door 400 adjusts the flow area of the second air opening 120, the flow rate of the cold air entering the downstream of the air duct 23 can be changed, so as to change the cold air input amount of the second sub-compartment 202. The first damper 300 and the second damper 400 are synchronously translated to synchronously adjust the flow area of the first tuyere 110. When the cold air input amount of the second sub-compartment 202 increases or decreases, the flow rate of the air flowing out through the first tuyere 110 also increases or decreases in synchronization.
Of course, in some alternative embodiments not illustrated in the drawings, the second tuyere 120 may also communicate with the first sub-chamber 201 and the second sub-chamber 202, so that the cold air of the second sub-chamber 202 is derived from the first sub-chamber 201. The cold air changes into hot air after flowing through the storage, and then flows back to the first sub-compartment 201 through the first air inlet 110, so as to complete the whole process of refrigeration of the second sub-compartment 202.
Fig. 5 is a schematic block diagram of a refrigeration and freezing apparatus according to an embodiment of the present invention. As shown in fig. 5, in some embodiments, the refrigeration and freezing apparatus may further include a temperature detection device 60, a temperature setting device 70, and a controller 50. Wherein the temperature detecting device 60 is configured to detect the current cooling temperature of the second sub-compartment 202, which may be at least one temperature sensor. The temperature setting device 70 is used to set the target cooling temperature of the second sub-compartment 202, and may be a knob or a touch screen, so that the user can set the desired target cooling temperature of the second sub-compartment 202. The controller 50 is configured to control the operation of the damper driving mechanism according to the difference between the target refrigeration temperature and the current refrigeration temperature, so as to adjust the flow areas of the first tuyere 110 and the second tuyere 120, and further adjust the cold air flow rate of the second sub-chamber 202, so that the current refrigeration temperature gradually approaches to the target refrigeration temperature. Therefore, the temperature of the second sub-chamber 202 is automatically adjusted, and the user experience is improved.
