Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration equipment, and in particular to a refrigerator. Background Art

[0002] As living standards improve, residents' expectations for their home environments are becoming increasingly demanding. Simple, stylish integrated kitchen appliances and smart home designs are gaining popularity. However, refrigerators, as essential kitchen appliances, are bulky and, when placed in a kitchen or living room, tend to protrude from the wall, hindering the rational layout and aesthetics of the space. Therefore, to achieve an integrated kitchen appliance design, refrigerators are often built into cabinets, making them appear as an integral part of the kitchen or living room.

[0003] However, when installing a conventional refrigerator, a minimum of 100mm of space is required around the refrigerator, including the rear wall, to ensure proper ventilation and heat dissipation of the compressor compartment, thereby reducing the refrigerator's energy consumption. Because there is ample space between the refrigerator and walls or other objects, the air inlet and outlet on the compressor compartment backplate at the lower rear of the refrigerator do not interfere with each other. When the refrigerator is embedded in a cabinet, to conserve space, the distance between the refrigerator and the cabinet is reduced, with the rear wall even placed close to the cabinet wall, and the distance between the side walls and the cabinet wall less than 30mm. This allows hot air from the air outlet on the compressor compartment backplate at the lower rear of the refrigerator to easily flow through the air inlet into the compressor compartment, increasing the air temperature inside the compressor compartment. This increases the refrigerator's energy consumption, reduces the performance of the condenser and compressor, and even leads to safety issues such as reduced compressor reliability due to poor heat dissipation from the compressor compartment. Summary of the Invention

[0004] In order to solve the problem that when a refrigerator is embedded in a cabinet, the hot air discharged from the compressor compartment flows into the compressor compartment again, resulting in increased energy consumption of the refrigerator and decreased performance of the condenser and compressor, the purpose of the present invention is to provide a refrigerator.

[0030] The present application will be described in detail below with reference to the various embodiments shown in the drawings.

[0031] In various diagrams of the present application, certain dimensions of structures or parts are exaggerated relative to other structures or parts for the purpose of illustration, and thus, only the basic structure of the subject matter of the present application is illustrated.

[0032] It should be understood that although the terms first, second, etc. can be used herein to describe various elements or structures, these elements or structures should not be limited by these terms. These terms are only used to distinguish one element or structure from another.

[0033] Embodiment 1

[0034] Referring to Figures 1 to 2 , the refrigerator 100 provided by an embodiment of the present application comprises a compressor compartment 1 arranged at the lower rear part thereof, a front wall 2 and a rear wall 3 arranged opposite to each other, a pair of side walls 4 arranged opposite to each other, and a storage chamber. The storage chamber is enclosed by the front wall 2, the rear wall 3, and the pair of side walls 4.

[0035] Referring to Figure 3 , the compressor compartment 1 comprises an inner space 11, a compartment wall 12 enclosing the inner space 11, and a heat dissipation fan 13, a compressor 14, and an evaporator 15 arranged in the inner space 11. The compartment wall 12 comprises a back plate 121 arranged at the rear of the inner space 11, and a bottom plate 122 arranged at the lower part of the inner space 11.

[0036] Referring to Figures 4 to 5 , the compartment wall 12 is provided with a first air port 123, a second air port 124, and a third air port. Specifically, in the present embodiment, the back plate 121 of the compressor compartment 1 is provided with the first air port 123 and the second air port 124 arranged side by side. The first air port 123 and the second air port 124 are respectively in communication with the space at the rear of the refrigerator 100, i.e. in communication with the outside, so as to facilitate the air flow exchange between the compressor compartment 1 and the outside environment through the rear part thereof. The bottom plate 122 of the compressor compartment 1 is provided with the third air port in communication with the space at the lower part of the refrigerator 100, i.e. in communication with the outside, so as to facilitate the air flow exchange between the compressor compartment 1 and the outside environment through the bottom part thereof. In other embodiments, the first air port 123 and the second air port 124 can also be arranged on the bottom plate 122, and the third air port 124 is arranged on the back plate.

[0037] Among them, the first air outlet 123 can be an air inlet or an air outlet; when the first air outlet 123 is an air inlet, the second air outlet 124 is an air outlet, and the third air outlet is also an air inlet; when the first air outlet 123 is an air outlet, the second air outlet 124 is an air inlet, and the third air outlet is also an air outlet.

[0038] Through the first air outlet 123, the second air outlet 124 and the third air outlet set on the warehouse wall 12, the built-in space 11 of the compressor warehouse 1 has a first air path and a second air path. The first air path is connected from the first air outlet 123124 to the second air outlet 124123 through the heat dissipation fan 13, and the second air path is connected from the third air outlet 124 to the second air outlet 124 through the heat dissipation fan 13.

[0039] For ease of description, in this embodiment, the rear wall 3 of the refrigerator 100 facing the user is used as a reference, the direction from the rear wall 3 toward the front wall 2 of the refrigerator 100 is defined as the back-to-front direction, i.e., the front wall 2 of the refrigerator 100 is located in front of the rear wall 3, and the direction from the second air vent 124 toward the first air vent 123 is defined as the left-to-right direction, i.e., the first air vent 123 is located to the right of the second air vent 124. Therefore, the side wall 4 closer to the first air vent 123 is defined as the right side wall, and the side wall 4 farther from the first air vent 123 is defined as the left side wall. In other embodiments, the first air vent 123 may also be located to the left of the second air vent 124.

[0040] See Figures 4 to 5 as well as Figures 7 to 8 The refrigerator 100 further includes a shielding member for opening or closing the first air vent 123. When the first air vent 123 is open, both the first air path and the second air path form a circulation loop with the outside world; when the first air vent 123 is closed by the shielding member, the second air path forms a circulation loop with the outside world.

[0041] In the embodiment, the shielding member is a baffle 16 movably arranged at the first air inlet 123. The baffle 16 has a first position in which the first air inlet 123 is open, and a second position in which the first air inlet 123 is closed. By arranging the baffle 16, when the refrigerator 100 is embedded in the cabinet 200, the first air inlet 123 on the back plate 121 of the pressurized chamber 1 can be closed, so that the pressurized chamber 1 uses the second air path, i.e., the air circulates through the third air inlet on the bottom plate 122 of the pressurized chamber 1, the heat dissipation fan 13, and the second air inlet 124 on the back plate 121 of the pressurized chamber 1. By changing the path of the air inlet and outlet in the pressurized chamber 1, the hot air discharged from the pressurized chamber 1 and the cold air sucked into the pressurized chamber 1 do not flow into each other, so that the high-efficiency heat dissipation of the pressurized chamber 1 after the refrigerator 100 is embedded in the cabinet 200 is achieved, and the cold and hot air flow caused by the first air inlet 123 and the second air inlet 124 on the back plate 121 of the pressurized chamber 1 when the first air path is used, i.e., the first air inlet 123 on the back plate 121 of the pressurized chamber 1 is communicated with the second air inlet 124 on the back plate 121 of the pressurized chamber 1 through the heat dissipation fan 13, is avoided, so that the temperature of the air in the pressurized chamber 1 is relatively high, thereby affecting the performance of the compressor 14 and the condenser, and increasing the energy consumption of the refrigerator 100.

[0042] The baffle 16 can be arranged on the inner side of the back plate 121, or can be arranged on the outer side of the back plate 121 according to the aesthetic requirements.

[0043] Referring to Figures 5 to 7 Further, the refrigerator 100 further comprises a driving mechanism 17 for driving the baffle 16 to move between the first position and the second position, so that the baffle 16 opens or shields the first air inlet 123.

[0044] Referring to Figures 5 to 6 Further, the driving mechanism 17 is a push rod 171 which moves left and right relative to the baffle 16 to push the baffle 16 to move from the first position to the second position, i.e., the baffle 16 shields the first air inlet 123 to make the first air inlet 123 in a closed state. The push rod 171 has a first end 1711 and a second end 1712 arranged left and right relative to each other, and the first end 1711 is connected with the baffle 16. When the baffle 16 is in the first position, the second end 1712 protrudes out of the side wall 4 of the refrigerator 100 in the left and right directions.

[0045] In this embodiment, the first end 1711 is located at the left end of the push rod 171, while the second end 1712 is located at the right end of the push rod 171. When the baffle 16 is in the first position, the second end 1712 protrudes rightwardly and horizontally beyond the right side wall 4 of the refrigerator 100. Thus, when the refrigerator 100 is inserted into the cabinet 200, the second end 1712 of the push rod 171 interferes with the cabinet 200 wall. Under the action of the cabinet 200 wall, the second end 1712 of the push rod 171 is forced to move leftwardly and horizontally, pushing the baffle 16 to move leftwardly and horizontally, thereby shielding the first air vent 123 and closing the first air vent 123.

[0046] In other embodiments, when the first air vent 123 is located to the left of the second air vent 124, the first end 1711 is located at the right end of the push rod 171, while the second end 1712 is located at the left end of the push rod 171. When the baffle 16 is in the first position, the second end 1712 protrudes leftwardly and horizontally beyond the left side wall 4 of the refrigerator 100. When the refrigerator 100 is embedded in the cabinet 200, the second end 1712 of the push rod 171 interferes with the cabinet 200 wall. Under the action of the cabinet 200 wall, the second end 1712 of the push rod 171 is forced to move rightwardly and horizontally, pushing the baffle 16 to the right to shield the first air vent 123, thus closing the first air vent 123.

[0047] See Figure 6 Furthermore, the end surface of the second end 1712 is configured as an arcuate or inclined surface that gradually moves away from the side wall 4 from the rear to the front. When the refrigerator 100 is inserted into the cabinet 200, the rear end surface of the second end 1712 first abuts against the wall of the cabinet 200, then transitions along the arcuate end surface to the front end surface abutting against the wall of the cabinet 200. Under the action of the wall of the cabinet 200, the push rod 171 gradually moves from right to left. In this way, the relative movement of the end surface of the second end 1712 and the wall of the cabinet 200 in the front-to-back direction not only saves effort but also prevents the second end 1712 from damaging the wall of the cabinet 200.

[0048] See Figures 5 to 6Furthermore, the drive mechanism 17 further includes an elastic member 172 connecting the back plate 121 and the push rod 171. The elastic member 172 drives the baffle 16 to return from the second position to the first position via the push rod 171, and enables the push rod 171 to stably drive the baffle 16 in the left-right direction. When the baffle 16 is in the first position, the elastic member 172 has a first deformation. When the baffle 16 is in the second position, the elastic member 172 has a second deformation. The second deformation is greater than the first deformation. That is, when the drive mechanism 17 drives the baffle 16 from the first position to the second position, the drive mechanism 17 acts on the elastic member 172 to cause it to further elastically deform. When the baffle 16 is in the second position, when the external force is removed, the elastic member 172 has an elastic restoring force to overcome its elastic deformation and drive the baffle 16 to return from the second position to the first position. In this embodiment, the elastic member 172 is located on the right side of the first air outlet 123.

[0049] See Figures 5 to 6 In order to further enable the push rod 171 to move stably in the left and right directions and thus drive the baffle 16 to move stably left and right, the back plate 121 is provided with a guide rail 173 extending in the left and right directions. The elastic member 172 is a spring sleeved on the outer periphery of the push rod 171. The push rod 171 and the spring are built into the guide rail 173. A limiting portion 1731 is provided on the inner wall of the guide rail 173. A flange 1713 is provided on the push rod 171. The end of the spring close to the first air outlet 123, that is, the left end, abuts against the limiting portion 1731, and the end of the spring away from the first air outlet 123, that is, the right end, abuts against the flange 1713. Push rod 171 compresses the spring and pushes baffle 16 from the first position to the second position. The end of the spring, located near first air outlet 123, is fixed relative to back plate 121. When push rod 171 pushes baffle 16 from the first position to the second position, flange 1713 of push rod 171 abuts against the right end of the spring and compresses it to the left, causing it to elastically deform. In other embodiments, elastic member 172 may also be in the form of a bellows, rubber tube, or the like, as long as it is elastically deformable.

[0050] See Figures 4 to 5 as well as Figures 7 to 8Furthermore, a limiting member 1211 is provided on the back panel 121. Specifically, in this embodiment, the limiting member 1211 is a limiting column. When the baffle 16 is in the first position, the baffle 16 opens the first air outlet 123, and a gap is formed between the baffle 16 and the limiting member 1211. When the baffle 16 is in the second position, the limiting member 1211 abuts against the baffle 16 and restricts the baffle 16 from moving from the second position away from the first position. The setting of the limiting member 1211 limits the extreme position of the baffle 16's leftward movement, ensuring that the baffle 16 just moves to the second position to cover the first air outlet 123, and prevents the baffle 16 from moving to a position misaligned with the first air outlet 123 and failing to completely cover the first air outlet 123, causing the hot air discharged from the compressor chamber 1 to flow into the compressor chamber 1, thereby causing problems such as increased energy consumption of the refrigerator 100 and decreased performance of the condenser and compressor 14.

[0051] Furthermore, the refrigerator 100 also includes a control system, which includes a collection unit and a fan control unit. The collection unit is used to collect the power-on signal of the refrigerator 100, as well as the closing signal and opening signal of the first air vent 123. The fan control unit is connected to the collection unit and is used to control the heat dissipation fan 13 to operate at a set speed Nf1 when the collection unit collects the opening signal of the first air vent 123; when the collection unit collects the closing signal of the first air vent 123 and the power-on signal of the refrigerator 100, control the heat dissipation fan 13 to operate at a set speed Nf2; wherein Nf2>Nf1.

[0052] Preferably, Nf2 is 110% to 120% times of Nf1, and both Nf1 and Nf2 do not exceed the rated speed of the heat dissipation fan 13.

[0053] In this way, when the first air vent 123 is closed and the refrigerator 100 is powered on, that is, when the refrigerator 100 is embedded in the cabinet 200 and turned on, by collecting relevant signals and controlling the speed of the heat dissipation fan 13 to increase, the discharge volume and discharge efficiency of hot air, as well as the intake volume and intake efficiency of cold air can be increased, and the problem of poor heat dissipation caused by the reduction of air vents for air exchange between the compressor chamber 1 and the outside world can be solved, thereby realizing automatic control and intelligence of the refrigerator 100.

[0054] Furthermore, the collection unit is also used to collect the temperature of the storage compartment; the fan control unit is also used to: when the collection unit collects the closing signal of the first air outlet 123 and the power-on signal of the refrigerator 100, control the heat dissipation fan 13 to operate at a set speed Nf2 until the temperature of the storage compartment reaches the set temperature T, and then control the heat dissipation fan 13 to operate at a set speed Nf1.

[0055] See Figure 8Furthermore, the refrigerator 100 also includes a first conductive end 18 provided on the shielding member and a second conductive end 19 provided on the compartment wall 12. Specifically, in this embodiment, the first conductive end 18 is provided on the baffle 16, and the second conductive end 19 is provided on the limiting member 1211. When the baffle 16 is in the first position, that is, when the shielding member opens the first air outlet 123, the first conductive end 18 and the second conductive end 19 are separated, and the collection unit collects the opening signal of the first air outlet 123. When the baffle 16 is in the second position, that is, when the shielding member closes the first air outlet 123, the first conductive end 18 and the second conductive end 19 are in contact and generate an electrical signal, and the collection unit collects the closing signal of the first air outlet 123.

[0056] To ensure that the first conductive end 18 contacts the second conductive end 19 on the limiting post when the baffle 16 is in the second position, the left end of the first conductive end 18 is located at the left edge of the baffle 16 corresponding to the limiting post. The shape of the first conductive end 18 is not limited, as long as it does not affect the baffle 16 from shielding the first air outlet 123.

[0057] Furthermore, the control unit is further configured to control the compressor 14 to operate at a set speed Nc1 when the acquisition unit detects an on signal from the first air vent 123; and to control the compressor 14 to operate at a set speed Nc2 when the acquisition unit detects a off signal from the first air vent 123 and a power-on signal from the refrigerator 100; wherein Nc2>Nc1. In this way, when the first air vent 123 is closed and the refrigerator 100 is powered on, that is, when the refrigerator 100 is embedded in the cabinet 200 and turned on, rapid cooling can be achieved, allowing the refrigerator 100 to quickly reach the set temperature T.

[0058] Preferably, Nc2 is 102% to 110% times of Nc1, and both Nc1 and Nc2 do not exceed the rated speed of the compressor 14.

[0059] See Figure 2 Furthermore, the back panel 121 is provided with two flanges 1212 disposed in an upper and lower position, extending in the left-right direction. The upper and lower ends of the baffle 16 are respectively inserted into the grooves of the flanges 1212 to limit the trajectory of the baffle 16's lateral movement. The baffle 16 can slide in the left-right direction relative to the flanges 1212 to reciprocate between the first position and the second position. The flanges 1212 are positioned to match the baffle 16. When the baffle 16 is located on the inner side of the back panel 121, the flanges 1212 are also located on the inner side of the back panel 121; when the baffle 16 is located on the outer side of the back panel 121, the flanges 1212 are also located on the outer side of the back panel 121.

[0060] See Figures 4 to 5The baffle 16 includes an opening 161 and a rib 162 arranged at intervals. When the baffle 16 is in the first position, the opening 161 is aligned with the first air outlet 123 to open the first air outlet 123; when the baffle 16 is in the second position, the rib 162 covers the first air outlet 123 to close the first air outlet 123. The width of the gap between the baffle 16 and the limiting member 1211 is the same as the width of the opening 161. In this way, when the baffle 16 moves to abut the limiting member 1211, the rib 162 just covers the first air outlet 123.

[0061] Example 2

[0062] The difference between Example 2 and Example 1 is that:

[0063] The driving mechanism 17 is an electric driving mechanism. The control system further includes a driving control unit connected to the electric driving mechanism. Under the control of the driving control unit, the electric driving mechanism is turned on to drive the shielding member to close the first air outlet 123 .

[0064] See Figure 7 The electric drive mechanism includes an electromagnet 174 and a magnetic block 175. One of the electromagnet 174 and the magnetic block 175 is disposed on the back plate 121, and the other of the electromagnet 174 and the magnetic block 175 is disposed on the baffle 16. When energized, the electromagnet 174 cooperates with the magnetic block 175 to drive the baffle 16 from the first position to the second position. Specifically, in this embodiment, the electromagnet 174 is disposed on the back plate 121, and the magnetic block 175 is disposed on the baffle 16.

[0065] Furthermore, the refrigerator 100 further includes an elastic return member 176 , which drives the baffle 16 to return from the second position to the first position to open the first air vent 123 .

[0066] Furthermore, the refrigerator 100 also includes a sensor, which detects position information between the refrigerator 100 and the obstacle.

[0068] Embodiment 2 is identical to Embodiment 1 except for the above-mentioned differences, which will not be repeated here.

[0069] Embodiment 3

[0070] Referring to Figure 9 The application also provides a control method of the refrigerator 100, comprising the steps of:

[0071] collecting a power-on signal of the refrigerator 100 and a closing signal of the first air outlet 123;

[0072] when the opening signal of the first air outlet 123 is collected and the first air path and the second air path form a circulation loop with the outside, controlling the heat dissipation fan 13 in the compressor chamber 1 to operate at a set speed Nf1;

[0073] when the power-on signal of the refrigerator 100 is collected and the closing signal of the first air outlet 123 is collected, and the second air path forms a circulation loop with the outside, controlling the heat dissipation fan 13 to operate at a set speed Nf2;

[0074] wherein Nf2>Nf1.

[0075] In this way, when the refrigerator 100 is powered on and the first air outlet 123 is closed, that is, when the refrigerator 100 is embedded in the cabinet 200 and turned on, by increasing the speed of the heat dissipation fan 13, the exhaust amount and efficiency of hot air, and the air intake amount and efficiency of cold air can be improved, solving the problem of poor heat dissipation caused by the reduction of air exchange ports between the compressor chamber 1 and the outside, and realizing the automatic control and intelligentization of the refrigerator 100.

[0076] Further, the control method of the refrigerator 100 further comprises the steps of:

[0077] when the power-on signal of the refrigerator 100 is collected and the closing signal of the first air outlet 123 is collected, and the second air path forms a circulation loop with the outside, controlling the heat dissipation fan 13 to operate at a set speed Nf2, until the temperature of the storage compartment of the refrigerator 100 reaches the set temperature T, controlling the heat dissipation fan 13 to operate at a set speed Nf1.

[0078] When the temperature of the storage compartment reaches the set temperature of the refrigerator 100, the heat dissipation fan 13 can operate at a normal speed to realize normal heat dissipation of the compressor chamber 1.

[0079] In order to illustrate the improvement effect of the refrigerator 100 of the present embodiment on the cold and hot air flow in the compressor chamber, the heat dissipation of the compressor chamber of the refrigerator is simulated, and the environmental temperature is 32℃, as follows:

[0080] The control group 1: the simulation of the ordinary refrigerator without being embedded in the cabinet, the distance between the left and right side walls of the refrigerator and the obstacle is set to 100mm, wherein the first air port and the second air port are arranged on the back plate of the compressor chamber, the third air port is arranged on the bottom plate of the compressor chamber, and the first air port, the second air port and the third air port are in the open state, and the simulation effect diagram is shown in Figure 10 ;

[0081] The control group 2: the simulation of the ordinary refrigerator embedded in the cabinet, the distance between the left and right side walls of the refrigerator and the obstacle is set to 3mm, wherein the first air port and the second air port are arranged on the back plate of the compressor chamber, the third air port is arranged on the bottom plate of the compressor chamber, and the first air port, the second air port and the third air port are in the open state, and the simulation effect diagram is shown in Figure 11 ;

[0082] The test group: the simulation of the refrigerator of the embodiment embedded in the cabinet, the distance between the left and right side walls of the refrigerator and the obstacle is set to 3mm, wherein the first air port and the second air port are arranged on the back plate of the compressor chamber, the third air port is arranged on the bottom plate of the compressor chamber, the first air port is in the closed state, and the second air port and the third air port are in the open state, and the simulation effect diagram is shown in Figure 12 .

[0083] The simulation analysis of the above three groups of refrigerators is carried out, and the simulation analysis results of the effective air volume, the average temperature of the inlet air and the average temperature of the condenser of the three groups of refrigerators are as follows:

[0084] Indicators Control group 1 Control group 2 Test group Effective air volume (L / min) 1513 1120 1379 Average temperature of incoming air (°C) 32.5 36.9 32.7 Average temperature of condenser (°C) 41.9 45.7 42.1

[0085] Referring to Figures 10 to 12 , combined with the simulation analysis data, it can be seen that when the ordinary refrigerator is embedded in the cabinet, the hot air discharged from the air port on the back plate of the compressor chamber will flow into the compressor chamber, resulting in an increase in the average temperature of the inlet air in the compressor chamber and a decrease in the effective air volume, and the temperature of the condenser is also significantly increased; compared with the ordinary refrigerator, when the refrigerator of the embodiment is embedded in the cabinet, by shielding the first air port, the hot air discharged from the compressor chamber can be effectively prevented from flowing into the compressor chamber, the effective air volume entering the compressor chamber is increased, the average temperature of the inlet air in the compressor chamber and the average temperature of the condenser are reduced, and the effect close to that of the normal refrigerator without being embedded in the cabinet is achieved.

[0086] That is, the refrigerator 100 of the embodiment changes the path of the heat dissipation inlet air and outlet air in the compressor chamber 1, so that the hot air discharged from the compressor chamber 1 and the cold air sucked into the compressor chamber 1 do not flow into each other, thereby avoiding the problems of cold and hot air flow, high inlet air temperature in the compressor chamber 1, performance influence of the compressor 14 and the condenser, and increased energy consumption of the refrigerator 100 caused by the first air port 123 and the second air port 124 being located on the back plate 121 of the compressor chamber 1.

When the refrigerator 100 is embedded in the cabinet 200, the baffle 16 can be used to automatically close the first air outlet 123 with the help of the cabinet 200, and the push rod 171 can be reset and stabilized by the spring, and the push rod 171 can be guided and stabilized by the guide rail 173; the baffle 16 can be automatically controlled to close the first air outlet 123 by the cooperation of the electromagnet 174 and the magnetic block 175, and the magnetic block 175 can be reset by the reset spring 176; A first conductive end 18 and a second conductive end 19 are provided on the baffle 16 and the back plate 121. When the baffle 16 moves to close the first air outlet 123, an electrical signal is generated. By providing a limiter 1211 on the back plate 121, the baffle 16 and the first air outlet 123 can be matched to just cover the first air outlet 123. By providing a control system, relevant signals of the refrigerator 100 are collected and the speed of the heat dissipation fan 13 is controlled to increase, so as to increase the exhaust volume and exhaust efficiency of hot air and the intake volume and intake efficiency of cold air, thereby solving the problem caused by The problem of poor heat dissipation caused by the reduced number of air vents for air exchange between the compressor compartment 1 and the outside world is addressed, thereby achieving automatic control and intelligentization of the refrigerator 100. A sensor is provided to detect the position information of the refrigerator 100 and obstacles to determine whether the refrigerator 100 is embedded in the cabinet 200, thus achieving intelligentization of the refrigerator 100. In addition, the control method of the refrigerator 100 collects the power-on signal of the refrigerator 100 and the opening and closing signals of the first air vent 123 to control the speed change of the heat dissipation fan 13, greatly improving the intelligence level of the refrigerator 100. Simulation tests further verified that when the refrigerator of this embodiment is embedded in the cabinet, it can effectively prevent the hot air discharged from the compressor compartment from flowing into the compressor compartment, increase the effective air volume entering the compressor compartment, and reduce the average temperature of the incoming air in the compressor compartment and the average temperature of the condenser.
