The operating principle of freezer includes: a temperature sensor provided in the refrigerating space 10 senses the temperature in the refrigerating space 10. When the temperature in the acquired refrigerating space 10 is greater than a set temperature (for example, a starting point), controlling the operation of the compressor to refrigerate in the refrigerating space 10; when the temperature in the collected refrigerating space 10 is less than the set temperature (for example, a shutdown point), the compressor is controlled to stop running.

The operating principle of freezer still includes: the refrigerator is provided with a door sensor for sensing the door opening and closing state. The refrigerator further comprises a main control unit, and the main control unit is connected with the door body sensor and the compressor. When the door body is opened, the door body sensor identifies the door opening state, and the main control unit receives the door opening signal to control the compressor to stop running, so that the energy consumption is reduced, and the leakage of cold is avoided. When the door body is closed, the door body sensor identifies the door closing state, the main control unit receives a door closing signal to cut off the control of the compressor, and the state of the compressor is controlled by the temperature control system. Wherein the door body sensor is a magnetic sensitive switch, a Hall switch or a mechanical switch.

The principle is applicable to vertical refrigerators and also applicable to horizontal refrigerators.

As shown in fig. 1, the cabinet 1 includes a top wall 2, a bottom wall 3, and a side wall 4, wherein the side wall 4 is disposed between the top wall 2 and the bottom wall 3. The side wall 4 comprises a first side wall section 5 and a second side wall section 6, the first side wall section 5 and the second side wall section 6 being located on the same side of the refrigerated space 10, e.g. both on the left or right side or the front or rear side of the refrigerated space 10, the second side wall section 6 being provided with a first air duct 7. The refrigerator further comprises a door body 8, wherein the door body 8 is arranged on the first side wall section 5 in an openable and closable manner so as to open or close the refrigerating space 10. The refrigerator further comprises an evaporator 9, and the evaporator 9 is arranged in the first air duct 7.

By adopting the refrigerator provided by the embodiment of the disclosure, the evaporator 9 is arranged at the side wall (the second side wall section 6), so that the diversity of the internal structure of the refrigerator can be increased, and the design blank of the position of the evaporator is supplemented. Moreover, since the second side wall section 6 does not need to be opened and closed as the door body 8 does, there is no disadvantage in the related art that the opening and/or closing of the door body is laborious due to the provision of the evaporator to the door body.

Embodiment two:

on the basis of the first embodiment, as shown in fig. 2, the refrigerator optionally further comprises a third side wall section 11, wherein the third side wall section 11 is located on the other side of the refrigerating space 10 and is opposite to the first side wall section 5 and the second side wall section 6. The refrigerator further comprises a switch door 12, wherein the switch door 12 is arranged on the third side wall section 11 in an openable and closable manner so as to open or close the refrigerating space 10.

Most of the existing refrigerators are provided with only one door, and in use, goods are accumulated on the rear side of the shelf due to the fact that the front side of the shelf is held firstly, and goods are supplied to the spare positions on the front side by a goods supplying person during goods supplying, so that the goods on the rear side are accumulated until the goods are outdated for a long time. With the refrigerator provided by the embodiment of the present disclosure, there are two opposite doors (a door body 8 and a switch door 12) on the refrigerator, the switch door 12 is regarded as a front door, and the door body 8 is regarded as a rear door. Thus, when the rear door is opened during replenishment, the commodities at the rear side of the shelf 13 are moved forward to the front side of the shelf 13, and then the residual positions at the rear side of the shelf 13 are replenished, so that the problem of long-term backlog of the commodities at the rear side is solved, and the problem of first-in first-out of the commodities during replenishment is solved.

Optionally, the first side wall section 5 and the second side wall section 6 are arranged in a vertical direction.

Optionally, the first side wall section 5 and the second side wall section 6 are arranged in a horizontal direction.

The above arrangement positions of the first side wall section 5 and the second side wall section 6 are applicable to vertical refrigerators and also applicable to horizontal refrigerators.

As shown in fig. 2, the surface of the first side wall section 5 facing the second side wall section 6 is optionally provided with a first inclined surface 14, the first inclined surface 14 being inclined inwardly in the direction from the second side wall section 6 to the first side wall section 5. The surface of the second side wall section 6 facing the first side wall section 5 is provided with a second inclined surface 15 adapted to the first inclined surface 14.

In the direction from the second side wall section 6 to the first side wall section 5, the first inclined surface 14 is inclined inwards, and the second inclined surface 15 is inclined inwards, on the one hand, when the door body 8 is opened, sundries falling from the refrigerating space 10 can roll downwards along the second inclined surface 15 in time, so that the sundries are prevented from accumulating on the second inclined surface 15 to influence the opening and closing of the door body 8; on the other hand, the contact area of the first side wall section 5 and the second side wall section 6 can be increased, thereby enhancing the sealing effect of the door body 8 to the refrigerating space 10.

Alternatively, the surface of the first side wall section 5 facing the second side wall section 6 and the surface of the second side wall section 6 facing the first side wall section 5 can also be designed as a horizontal plane.

Optionally, the refrigerator further comprises a seal 16, the seal 16 being provided between the first side wall section 5 and the second side wall section 6.

Optionally, the seal 16 is a sealing rubber ring.

In this way, the sealing of the gap between the first side wall section 5 and the second side wall section 6 is more tight by squeezing the sealing rubber ring when closing the door, preventing cold air from leaking out of the refrigerated space 10 and/or ambient air from entering the refrigerated space 10.

Optionally, the refrigerator further comprises a first fan 17, and the first fan 17 is arranged in the first air duct 7. The first fan 17 is used for driving air in the refrigerating space 10 to flow into the first air duct 7, exchange heat with the evaporator 9 and flow out.

Alternatively, the first fan 17 is a centrifugal fan, an axial fan or a rotary fan. The first fan 17 may be located above the evaporator 9 or below the evaporator 9.

Alternatively, the evaporator 9 is a fin evaporator, or, a roll-bond evaporator.

Optionally, a second air duct 18 is provided in the door body 8 and is in communication with the first air duct 7.

In this way, the first fan 17 drives the hot air in the refrigerating space 10 to flow into the first air duct 7, the hot air in the first air duct 7 exchanges heat with the evaporator 9 to form cold air, the cold air flows along the first air duct 7 to the second air duct 18, and the cold air in the second air duct 18 can refrigerate the position, corresponding to the door body 8, on the refrigerating space 10, so that the temperature of the refrigerating space 10 is more uniform.

As shown in connection with fig. 6 and 7, optionally, a first through hole 23 is provided on the surface of the first side wall section 5 facing the second side wall section 6, and a second through hole 24 is provided on the surface of the second side wall section 6 facing the first side wall section 5, and the first through hole 23 communicates with the second through hole 24, so that the first air duct 7 communicates with the second air duct 18.

The first through holes 23 are formed in the surface, facing the second side wall section 6, of the first side wall section 5, the second through holes 24 are formed in the surface, facing the first side wall section 5, of the second side wall section 6, and the distance between the first through holes 23 and the second through holes 24 is reduced, so that the distance between the first air duct 7 and the second air duct 18 is shortened, the loss of cooling capacity when air flows between the first air duct 7 and the second air duct 18 is reduced, and the energy consumption of a refrigerator is reduced.

Alternatively, the first through hole 23 is disposed opposite to the second through hole 24. For example, when the first side wall section 5 is located above the second side wall section 6, the first through hole 23 is located directly above the second through hole 24; for another example, the first through hole 23 is located to the left of the second through hole 24 when the first side wall section 5 is located to the left of the second side wall section 6.

Optionally, the refrigerator further includes a baffle 25, where the baffle 25 is openably and closably provided in the second through hole 24 to open or close the second through hole 24.

Thus, when the door body 8 is opened, the shutter 25 closes the second through hole 24, prevents dirt from entering the first air duct 7 through the second through hole 24, and prevents cool air in the first air duct 7 from leaking. When the door 8 is closed, the shutter 25 opens the second through hole 24 to communicate the first air passage 7 with the second air passage 18.

Optionally, the refrigerator further comprises a driving device 26, and the driving device 26 is connected with the main control unit and is in driving connection with the baffle 25.

When the door body 8 is opened, the main control unit receives a door opening signal of the door body 8 to control the driving device 26 to drive the baffle 25 to close the second through hole 24, so that dirt is prevented from entering the first air duct 7 through the second through hole 24, and cold air in the first air duct 7 is prevented from leaking. When the door body 8 is closed, the main control unit receives a door closing signal of the door body 8 to control the driving device 26 to drive the baffle 25 to open the second through hole 24, so that the first air duct 7 is communicated with the second air duct 18.

The shutter 25 is rotatably or slidably connected to the cabinet 1 such that the shutter 25 opens or covers the second through hole 24.

Optionally, the first air duct 7 is provided with a first air return opening 19, and the second air duct 18 is provided with a first air outlet opening 20.

In this way, the hot air in the refrigerating space 10 enters the first air duct 7 through the first air return opening 19, so that the first air duct 7 returns air. The air flowing into the first air duct 7 exchanges heat with the evaporator 9 to form cold air, the cold air flows into the second air duct 18, and the cold air in the second air duct 18 flows out from the first air outlet 20 to the refrigerating space 10, so that air outlet of the second air duct 18 is realized.

Optionally, the first air duct 7 is further provided with a third air outlet 21, the third air outlet 21 is located at the downstream of the evaporator 9, and cold air after heat exchange with the evaporator 9 flows into the refrigerating space 10 through the third air outlet 21.

Alternatively, the number of the first air outlets 20 is one or more, and when the number of the first air outlets is plural, the plurality of first air outlets 20 are sequentially arranged along the up-down direction.

As shown in fig. 3, optionally, the refrigerator further includes: a first air duct cover plate 27, the first air duct cover plate 27 being for covering the first air duct 7; the second air duct cover 28, the second air duct cover 28 is used for covering the second air duct 18.

As shown in connection with fig. 2, the refrigerator optionally further comprises: the water receiving box 22, the water receiving box 22 is arranged right below the evaporator 9 and is used for collecting defrosting water. Wherein, the outlet of the water receiving box 22 is connected with the water outlet of the inner container, and can discharge the defrosting water to the outside of the cabinet body 1.

In summary, when the door body 8 is closed, the door body sensor recognizes the door closing state of the door body 8, the main control unit receives the door closing signal to cut off the control of the compressor, and the state of the compressor is controlled by the temperature control system. When the temperature in the refrigerating space 10 collected by the temperature sensor is greater than the set temperature (for example, a starting point), the compressor is controlled to operate to refrigerate the refrigerating space 10, the first fan 17 drives hot air in the refrigerating space 10 to flow into the first air duct 7 through the first air return opening 19, and the hot air in the first air duct 7 exchanges heat with the evaporator 9 to form cold air. Because the door body 8 is in a closed state at this time, the main control unit receives a door closing signal of the door body 8 to control the driving device 26 to drive the baffle 25 to open the second through hole 24, so that the cool air can diffuse along the communicated first air duct 7 and the second air duct 18, and flow out to the refrigerating space 10 through the third air outlet 21 and the first air outlet 20, so that the temperature of the refrigerating space 10 is more uniform. When the temperature in the refrigerating space 10 collected by the temperature sensor is smaller than the set temperature (for example, a shutdown point), the compressor is controlled to stop running, and the energy consumption is reduced.

When the door body 8 is opened, the door body sensor identifies the door opening state, and the main control unit receives the door opening signal to control the compressor to stop running, so that the energy consumption is reduced and the leakage of cold is avoided. When the door body 8 is opened, the main control unit receives a door opening signal of the door body 8 to control the driving device 26 to drive the baffle 25 to close the second through hole 24, so that dirt is prevented from entering the first air duct 7 through the second through hole 24, and the first air duct 7 is kept clean.

In this way, the second fan 29 drives the hot air in the refrigerating space 10 to flow into the second air duct 18 and then into the first air duct 7 communicated with the second air duct 18, and exchanges heat with the evaporator 9 in the first air duct 7 to form cold air, and the cold air in the first air duct 7 can refrigerate the position on the refrigerating space 10 corresponding to the second side wall section 6.

As shown in connection with fig. 6 and 7, optionally, a first through hole 23 is provided on the surface of the first side wall section 5 facing the second side wall section 6, and a second through hole 24 is provided on the surface of the second side wall section 6 facing the first side wall section 5, and the first through hole 23 communicates with the second through hole 24, so that the first air duct 7 communicates with the second air duct 18.

The first through hole 23 is arranged on the surface of the first side wall section 5 facing the second side wall section 6, the second through hole 24 is arranged on the surface of the second side wall section 6 facing the first side wall section 5, and the distance between the first through hole 23 and the second through hole 24 is reduced, so that the distance between the first air duct 7 and the second air duct 18 is shortened, and the flow speed of air between the first air duct 7 and the second air duct 18 is accelerated.

Alternatively, the first through hole 23 is disposed opposite to the second through hole 24. For example, when the first side wall section 5 is located above the second side wall section 6, the first through hole 23 is located directly above the second through hole 24; for another example, the first through hole 23 is located to the left of the second through hole 24 when the first side wall section 5 is located to the left of the second side wall section 6.

Optionally, the first air duct 7 is provided with a second air outlet 30, and the second air duct 18 is provided with a second air return 31.

In this way, the hot air in the refrigerating space 10 enters the second air duct 18 through the second air return opening 31, so that the second air duct 18 returns air. The hot air flows into the first air duct 7 communicated with the second air duct 18 along the second air duct 18, exchanges heat with the evaporator 9 in the first air duct 7 to form cold air, and the cold air flows out from the second air outlet 30 to the refrigerating space 10 to realize air outlet of the first air duct 30.

Optionally, the first air duct 7 is further provided with a fourth air outlet 32, the fourth air outlet 32 is located below the top end (including the top end) of the evaporator 9, and cold air after heat exchange with the evaporator 9 flows into the refrigerating space 10 through the fourth air outlet 32.

In summary, when the door body 8 is closed, the door body sensor recognizes the door closing state of the door body 8, the main control unit receives the door closing signal to cut off the control of the compressor, and the state of the compressor is controlled by the temperature control system. When the temperature in the refrigerating space 10 collected by the temperature sensor is greater than the set temperature (for example, the starting point), the compressor is controlled to operate to refrigerate the refrigerating space 10, and the second fan 29 drives the hot air in the refrigerating space 10 to flow into the second air duct 18 through the second air return opening 31. Because the door body 8 is in a closed state at this time, the main control unit receives a door closing signal of the door body 8 to control the driving device 26 to drive the baffle plate 25 to open the second through hole 24, so that hot air can diffuse to the first air duct 7 along the communicated second air duct 18, cold air is obtained after the hot air exchanges heat with the evaporator 9 in the first air duct 7 and flows out to the refrigerating space 10 through the second air outlet 30 and the fourth air outlet 32, and the descending speed is high due to high cold air density, so that the cold air can quickly descend to the bottom end of the refrigerating space 10, and the refrigerating speed is improved. When the temperature in the refrigerating space 10 collected by the temperature sensor is smaller than the set temperature (for example, a shutdown point), the compressor is controlled to stop running, and the energy consumption is reduced.

When the door body 8 is opened, the door body sensor identifies the door opening state, and the main control unit receives the door opening signal to control the compressor to stop running, so that the energy consumption is reduced and the leakage of cold is avoided. When the door body 8 is opened, the main control unit receives a door opening signal of the door body 8 to control the driving device 26 to drive the baffle 25 to close the second through hole 24, so that dirt is prevented from entering the first air duct 7 through the second through hole 24, and the first air duct 7 is kept clean.
