Background
The air-cooled refrigerator can keep food fresh, prolong the storage time of the food and improve the edible safety of the food, and is a necessary household appliance. The existing air-cooled refrigerator generally comprises at least a refrigerating chamber and a freezing chamber, cold air cooled by an evaporator directly flows into the refrigerating chamber and the freezing chamber through air ducts respectively, and the refrigerating chamber and the freezing chamber are provided with air outlets for the cold air to flow into respectively. Because the temperature of the cold air cooled by the evaporator is very low, when the cold air directly enters the refrigerating chamber through the air outlet, at least two defects exist: 1. articles in the refrigerating chamber, such as vegetables, fruits and the like, are easily frozen by cold air with low temperature, and particularly, the articles placed at the air outlet position in the refrigerating chamber are easily frozen; 2. the water loss of foods such as vegetables and fruits is accelerated, so that the foods such as vegetables and fruits are easy to shrivel. Particularly, when a large amount of food is put into the refrigerating chamber at one time and the refrigerating chamber needs to continuously carry out cooling work for a long time, the food near the air outlet of the refrigerating chamber bears greater freezing and air drying risks.
Disclosure of Invention
At least one problem to be solved by the present invention is the problem that food in a storage compartment like a cold storage compartment or a temperature changing compartment is easily frozen and air-dried.
In order to solve the above problems, the present invention provides a refrigerator including: a cooler chamber and a cooler disposed in the cooler chamber; a storage compartment for storing cooled articles; the air supply duct is provided with an air outlet communicated with the storage compartment; cold air from the cooler chamber cooled by the cooler flows to the air outlet along the air supply duct and enters the storage chamber; the air flow in the storage room returns to the air supply duct through the air inlet and/or the air inlet duct, is mixed with cold air in the air supply duct and then returns to the storage room through the air outlet.
The temperature of cold air blown into the storage compartment from the air supply duct is low, and the refrigeration temperature of food stored in a refrigerating chamber or a temperature change chamber is higher, so that the stored food is directly cooled by the cold air with low temperature and is easily frozen or dried by the air, and the stored food cannot achieve the storage effect expected by a user. And through set up the air inlet and/or enter the wind channel that communicates each other between storing room and air supply duct, can make the higher air of temperature in storing room return the air supply duct and mix with cold wind therein through above-mentioned air inlet and/or enter the wind channel, reach the temperature that improves the cold wind in the air supply duct, thus can avoid getting into the too low and apt to freeze the food or make the food air-dry and lose freshness easily of cold wind temperature in storing room.
As a further improvement of the present invention, in the cold air flow direction in the air supply duct, the air inlet and/or the air inlet duct is located at an upstream position of the air outlet.
Therefore, the cold air with lower temperature is mixed with the air with higher temperature from the storage chamber before entering the storage chamber through the air outlet, so that the temperature of the cold air entering the storage chamber is increased.
As a further improvement of the invention, the air inlet and/or the air inlet duct are/is positioned close to the bottom of the storage compartment.
Under the condition that the air supply air duct is closed by the air door, because there is the sinking phenomenon in the cold air in the storing compartment, lead to the air temperature of storing compartment bottom to be less than the air temperature on its upper portion, if the work of drumming through the fan this moment, the low temperature air of storing compartment bottom gets into the air supply air duct through going into the wind gap and/or going into the suction of wind channel, and to air supply air duct upper end air outlet, blow to the upper portion of storing compartment, thereby realize gas circulation between storing compartment and air supply air duct, make the temperature of storing compartment upper and lower part more even. In addition, the compressor does not need to be started in the process, and the energy consumption of the refrigerator is reduced.
As a further improvement of the invention, the air conditioner further comprises a first fan which is used for blowing the air flow of the storage compartment to pass through the air inlet and/or the air inlet channel and return to the air supply channel.
Through the blowing action of the fan, the air with higher temperature in the storage chamber can be returned to the air supply duct through the air inlet and/or the air inlet duct more dynamically, so that the cold air with lower temperature in the air supply duct can be mixed with enough air with higher temperature from the storage chamber, and the temperature of the cold air entering the storage chamber from the air supply duct is increased to a preset temperature range.
As a further improvement of the present invention, the first fan is disposed in the air inlet or the air inlet duct.
The fan is arranged in the air inlet or the air inlet channel, so that enough air with higher temperature from the storage compartment can be vigorously blown into the air supply channel.
As a further improvement of the present invention, the first fan is disposed such that a flow direction of the air flow blown from the storage compartment into the air supply duct intersects with and is not perpendicular to a flow direction of the cool air in the air supply duct.
Because the cold air current in the air supply duct and the air current that is blown into the air supply duct by the fan can lose some kinetic energy after mixing to influence the cold air after mixing and the power that advances forward along the air supply duct, and above-mentioned setting is so, not only can fine realization air mixing's effect, can avoid too much to lose the kinetic energy that the cold air after mixing moved forward again, guarantee that the cold air after mixing still has sufficient power and blows in into the storing room through the air outlet.
As a further improvement of the present invention, the rotation axis of the first fan intersects with the flow direction of the cold air in the air supply duct and is not perpendicular to each other.
Through so setting up the fan make by the air current that the fan was blown out can with the crossing and mutually non-perpendicular of flow direction of cold air in the air supply wind channel, can not only reach the effect of air mixing, avoid too much the power that the air conditioning that mixes went forward again.
As a further improvement of the present invention, the rotation axis of the first fan is parallel to the flow direction of the cool air in the supply air duct.
Through so set up the fan make the fan to blast the flow direction of the air current of coming out can with the flow direction of cold air is parallel to each other in the air supply wind channel to mix and move ahead along the air supply wind channel together, thereby can reduce the kinetic energy that the mixed air conditioning of loss moved ahead to the at utmost, guarantee that the mixed air conditioning still has enough power and blows in between the storing room through the air outlet.
As a further improvement of the present invention, the first fan is disposed in the air supply duct, and at least a part of the first fan covers the air inlet or the air inlet duct; and the rotation axis of the first fan is parallel to the flowing direction of the cold air in the air supply duct.
Through such setting, when the fan is blasted, the lower cold wind of temperature that flows along the air supply wind channel and the higher air current of temperature that returns the air supply wind channel through going into the wind gap or entering the wind channel are blasted and intensive mixing by the fan simultaneously together, and then go forward along the low reaches in air supply wind channel. And meanwhile, the blowing action of the fan also gives extra power for the mixed cold air to move forward along the downstream of the air supply duct, so that the mixed cold air has enough power to be blown into the storage chamber through the air outlet.
As a further improvement of the present invention, in the cold air flowing direction in the air supply duct, the first fan is disposed in the air supply duct and located at the downstream position of the air inlet and/or the air inlet duct.
The fan is arranged in such a way that enough and sufficient air with higher temperature from the storage compartment can be ensured to enter the air supply duct through the air inlet and/or the air inlet duct and be mixed with the cold air with lower temperature in the air supply duct.
As a further improvement of the invention, the first fan is arranged at a downstream position close to the air inlet and/or the air inlet duct.
So set up the fan and can guarantee the fan to come from the suction effect of the higher air of temperature in the storing compartment for the higher air of sufficient temperature is blown by the fan and is got into the air supply wind channel and mix with the lower air conditioning of temperature.

Detailed Description
The invention provides a new structural design of a refrigerator, which at least solves the problem that food in a storage chamber such as a refrigerating chamber or a temperature changing chamber is easy to freeze and dry.
The main inventive concept of the present invention is to provide a refrigerator, including: a cooler chamber and a cooler disposed in the cooler chamber; a storage compartment for storing cooled articles; the air supply duct is provided with an air outlet communicated with the storage compartment; cold air from the cooler chamber cooled by the cooler flows to the air outlet along the air supply duct and enters the storage chamber; the air flow in the storage room returns to the air supply duct through the air inlet and/or the air inlet duct, is mixed with cold air in the air supply duct and then returns to the storage room through the air outlet.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic longitudinal sectional view of a first embodiment of a refrigerator according to the present invention. The embodiment of the invention is described by taking a two-door refrigerator as an example, but the invention is not limited to the two-door refrigerator, and can also be applied to a three-door refrigerator, a side-by-side refrigerator or a multi-door refrigerator. As shown in fig. 1, the internal space of the refrigerator 100 is partitioned by a partition wall 7 into two separate storage compartments, namely, a storage compartment 1 and a second storage compartment 2. The refrigerating temperature of the storage compartment 1 is set to be higher than zero, and the second storage compartment 2 located below the storage compartment 1 is set to be a freezing compartment. In particular, a plurality of shelves 11 are also provided in the storage compartment 1 to divide the storage compartment 1 into different storage areas for placing different articles. Below the partition wall 7 is a cooler chamber 4, and a cooler 41 and a second fan 42 are installed in the cooler chamber 4. The back of the storage chamber 1 is provided with an air supply duct 3, the air supply duct 3 is defined by the back wall 12 of the storage chamber 1 and an air duct cover plate 31, and the air duct cover plate 31 is provided with a plurality of air outlets 32 arranged from top to bottom so as to convey cold air to different accommodating sections of the storage chamber 1. The air supply duct 3 is communicated with the cooler chamber 4 through a communicating passage 5, and an air door 6 capable of opening and closing the air supply duct 1 is further provided at a downstream section of the communicating passage 5. The air is cooled by the cooler 41 and then changed into cold air with lower temperature, and under the driving of the second fan 42, the cold air enters the air supply duct 3 along the communication channel 5 through the opened air door 6, and flows upwards and downwards along the air supply duct 3, and then enters the storage compartment 1 through the air outlets 32 distributed in the same accommodating section.
The temperature of the cold air blown into the storage compartment 1 from the air supply duct 3 is very low, usually far below zero, and the refrigeration temperature of the food stored in the storage compartment 1 which is set as a refrigerating chamber is relatively high, usually above zero, so that the stored food is directly cooled by the cold air with very low temperature and is easily frozen or air-dried, the stored food cannot achieve the storage effect expected by a user, and especially the food near the air outlet 32 of the storage compartment is more dangerous to freeze and air-dry. Therefore, in order to solve the problem, the air inlet 81 and/or the air inlet duct 8 communicated with each other are arranged between the storage compartment 1 and the air supply duct 3, so that air with higher temperature in the storage compartment 1 can return to the air supply duct 3 through the air inlet 81 and/or the air inlet duct 8 and be mixed with cold air in the air supply duct 3, the temperature of the cold air in the air supply duct 3 is increased, and the problem that the food is easily frozen to be damaged or the food is easily dried to lose freshness due to too low temperature of the cold air entering the storage compartment 1 can be avoided. In the present embodiment, an air inlet 81 and an air inlet duct 8 communicating with each other are provided between the storage compartment 1 and the air supply duct 3, the air inlet 81 directly faces the storage compartment 1, and the air inlet duct 8 intersects the air supply duct 3 in an upwardly inclined manner and is not perpendicular to each other. Under the action of the second fan 42, the cold air with lower temperature flows upwards along the air supply duct 3 with strong power, and drives the air with higher temperature from the storage compartment 1 entering the air duct 8 to enter and return to the air supply duct 3, and the air is mixed with the cold air in the air supply duct 3 and then flows downstream of the air supply duct 3.
Of course, in other embodiments, the air inlet 81 or the air inlet duct 8 communicating with each other may be provided only between the storage compartment 1 and the air supply duct 3.
In the storage compartment 1, a return air opening 15 is provided, and cold air is respectively returned to the cooler compartment 4 through the return air opening 15 into a return air passage (not shown) after the storage compartment 1 cools the stored articles. The cooler compartment 4 is provided with an inlet 43 communicating with the return air passage, through which inlet 43 the air is circulated back into the cooler compartment 4 and after cooling by the cooler 41 into the next air circulation.
Part of the cold air coming out of the cooler chamber 4 enters the second storage compartment 2, which is set as a freezing chamber, along the second air outlet duct 21, and reaches a specific area of the freezing chamber according to a designed route to cool the frozen articles. The cool air is returned to the cooler compartment 4 after cooling of the articles is completed, and thus enters the next air circulation, as is well known to those skilled in the art and will not be described further herein.
In order to ensure that the cool air with lower temperature in the air supply duct 3 can be mixed with enough air with higher temperature from the storage compartment 1, so that the temperature of the cool air entering the storage compartment 1 from the air supply duct 3 is increased to a predetermined temperature range, the first fan 9 can be arranged, and the air with higher temperature in the storage compartment 1 can more smoothly return to the air supply duct 3 through the air inlet 81 and/or the air inlet duct 8 under the action of the first fan 9.
Fig. 2 is a schematic longitudinal sectional view of a second embodiment of a refrigerator according to the present invention. The second embodiment shown in fig. 2 is different from the first embodiment shown in fig. 1 in that, in the flow direction of the cool air in the air supply duct 3 (i.e. the direction of the arrow vertically upward in the air supply duct in the figure), the first fan 9 is disposed in the air supply duct 3 and located at the downstream position of the air inlet 81 and/or the air inlet duct 8, and particularly, the first fan 9 is disposed at the downstream position close to the air inlet 81 and/or the air inlet duct 8, so that the suction effect of the first fan 9 on the air inlet 81 and/or the air inlet duct 8 can be ensured, and the air with higher temperature from the storage compartment 1 can be more easily sucked into the air supply duct 3 and sufficiently mixed.
As shown in fig. 2, the first fan 9 is disposed in the air supply duct 3, and at least a part of the first fan 9 covers the air inlet 81 or the air inlet duct 8; and the rotation axis of the first fan 9 is parallel to the flow direction of the cool air in the supply air duct 3. Specifically, the first fan 9 partially covers the connection between the air inlet duct 8 and the air supply duct 3, and at this time, air with high temperature from the air inlet duct 8 must pass through the first fan 9 to enter the air supply duct 3. The first fan 9 is disposed in such a manner that its rotation axis a is parallel to the flow direction of the cold air flowing vertically upward in the air supply duct 3 (i.e., the direction of the arrow vertically upward in the air supply duct in the drawing). With such arrangement, when the first fan 9 is driven, the cold air with lower temperature flowing along the air supply duct 3 and the air flow with higher temperature passing through the air inlet duct 8 are sucked and fully mixed by the first fan 9 at the same time, and then move forward along the downstream of the air supply duct 3; meanwhile, the blowing action of the first fan 9 also gives extra power to the mixed cold air to move forward along the vertical upward downstream direction of the air supply duct 3, so that the mixed cold air is ensured to be blown into the storage compartment 1 through the air outlet 32 more smoothly.
Fig. 3 is a schematic longitudinal sectional view of a third embodiment of a refrigerator according to the present invention. The third embodiment shown in fig. 3 differs from the first embodiment shown in fig. 1 in that the first fan 9 is disposed in the air inlet 81 or the air inlet duct 8, which helps to draw more vigorously enough air with a higher temperature from the storage compartment 1 to be introduced into the air supply duct 3 and mixed sufficiently. Specifically, as shown in fig. 4, the air inlet duct 8 intersects with the air supply duct 3 in an upward inclined manner and is not perpendicular to each other, the first fan 9 is disposed in the air inlet duct 8, and the rotation axis a of the first fan 9 intersects with and is not perpendicular to the flow direction of the cold air in the air supply duct 3 (i.e., the direction of the vertical upward arrow in the air supply duct in the figure), so that the airflow blown out by the first fan 9 can intersect with and is not perpendicular to the flow direction of the cold air in the air supply duct 3, for example, the airflow blown out by the first fan 9 can intersect with and form an acute angle with the flow direction of the cold air in the air supply duct 3, thereby achieving a good air mixing effect, avoiding excessive loss of kinetic energy of the mixed cold air moving forward, and ensuring that the mixed cold air still has enough power to be blown into the storage compartment 1 through the air outlet 32.
Because the cold air flow in the air supply duct and the air flow blown into the air supply duct by the fan lose part of kinetic energy after being mixed, in another embodiment, the air inlet duct is arranged in a mode of being parallel to the vertical upward air supply duct, the first fan is arranged in the air inlet duct, the rotation axis A of the first fan is also parallel to the vertical upward flow direction of the cold air in the air supply duct, so that the flow direction of the air flow blown out by the first fan can be parallel to the flow direction of the cold air in the air supply duct, and the air flow is mixed together to move forward along the air supply duct, thereby reducing the loss of the kinetic energy of the mixed cold air moving forward to the greatest extent, and ensuring that the mixed cold air still smoothly blows into the storage compartment through the air outlet.
The first fan 9 in all the above embodiments can be preferably configured as an axial flow fan, and an air inlet grille 33 facing the storage compartment 1 is further disposed in the air inlet 81 and/or the air inlet duct 8. The air inlet grille 33 is configured as a ventilation barrier between the air inlet 81 or the air inlet duct 8 and the storage compartment 1, on one hand, the air inlet 81 or the air inlet duct 8 is used as a decoration part to prevent the air inlet 81 or the air inlet duct 8 from being directly exposed in the storage compartment 1, so that the storage compartment 1 is more beautiful, and on the other hand, the air inlet 81 or the air inlet duct 8 is prevented from being directly entered by the hand of the object or the user, so that unnecessary consequences are caused, such as the object blocking the air inlet or the air inlet duct, or the hand of the user extending into the air inlet or the air inlet duct and being injured by the fan therein, and the like.
In the second and third embodiments, the air inlet 81 and/or the air inlet duct 8 are located at the upstream position of the air outlet 32 in the flow direction of the cool air in the air supply duct 3, and especially the air inlet 81 and/or the air inlet duct 8 are located at the position close to the bottom of the storage compartment 1. In this case, when the damper 6 closes the supply air duct 3, the first fan 9 may operate to blow air to circulate between the supply air duct 3 and the storage compartment 1, and particularly, the first fan 9 is controlled to operate intermittently.
Taking the situation of closing the air door in the third embodiment as an example, as shown in fig. 4, when the air supply duct 3 is closed by the air door 6, due to the sinking phenomenon of the cold air in the storage compartment 1, the air temperature at the bottom of the storage compartment 1 is lower than the air temperature at the upper part of the storage compartment, at this time, if the first fan 9 is driven, the low-temperature air at the bottom of the storage compartment 1 is sucked into the air supply duct 3 through the air inlet 81 and/or the air inlet duct 8 and flows to the air outlet 32 at the upper end of the air supply duct 3 to blow to the upper part of the storage compartment 1, so that the air circulation is realized between the storage compartment 1 and the air supply duct 3, and the air at different temperatures at the upper part and the lower part of the storage compartment 1 fully flows and mixes, so that the temperatures in different areas in the storage compartment 1 tend to be more. In addition, the compressor does not need to be started in the process, and the energy consumption of the refrigerator is reduced.
The arrows in the drawings in all the above embodiments indicate the circulation flow direction of the air in the refrigerator, that is, the arrows include: the air circularly flows among the storage compartment, the cooler compartment and the air supply duct; the air circularly flows between the storage chamber and the air supply duct; and circulation of air between the second storage compartment, the cooler compartment, and the second supply air duct, and so on.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
