Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a refrigeration device. Background Art

[0002] The refrigeration device includes a box body and a door body, wherein a storage chamber is formed in the box body for storing articles. The box body may include an outer shell and an inner liner arranged in the outer shell. The refrigeration device may also have an evaporator.

[0003] In order to better control the temperature of the storage room, a thermostat can be set on the refrigeration equipment. The thermostat can adjust the temperature level of the storage room, and the thermostat can also control the power on and off of the compressor.

[0004] At present, the thermostat generally has a knob and a shaft. The knob can be used to rotate the shaft to adjust the temperature level of the storage room. However, when the user accidentally touches the knob, the temperature level will be adjusted incorrectly, which will cause the temperature in the storage room to be wrong and easily cause the deterioration of the items. In the existing design, the knob is generally set to be hidden or difficult to adjust, which makes it difficult for the user to adjust and the user experience is poor. Therefore, it is necessary to propose a thermostat that prevents misadjustment and facilitates the adjustment of the temperature level. Therefore, the present application proposes a refrigeration device. Summary of the invention

[0005] The utility model aims to solve one of the technical problems in the related art at least to a certain extent.

[0006] To this end, according to an embodiment of the present disclosure, a refrigeration device is proposed, comprising:

[0007] A box body, a storage chamber is formed therein, and a box opening communicating with the storage chamber is formed on the box body; the box body comprises an outer shell and an inner liner, the inner liner is arranged in the outer shell, and an installation space is formed between the outer shell and the inner liner;

[0008] A door body, connected to the box body and used to open or close the box opening;

[0009] A compressor is arranged in the installation space;

[0010] An evaporator is arranged in the installation space or in the inner tank;

[0011] A thermostat, connected to the power supply circuit of the compressor to control the power on and off of the compressor, the thermostat is in contact with the evaporator or the inner tank and is used to adjust the temperature level of the storage chamber; the thermostat includes:

[0012] The first rotating shaft;

[0013] A first knob having at least a first position and a second position;

[0014] When the first knob is in the first position, the first knob cooperates with the first rotating shaft, and the first knob is rotated to rotate the first rotating shaft to adjust the temperature level of the storage chamber;

[0015] When the first knob is in the second position, the first knob is disengaged from the first rotating shaft, and the first rotating shaft does not rotate when the first knob is rotated;

[0016] A coil, wound on the first rotating shaft;

[0017] a magnet, connected to the first knob and at a certain distance from the coil;

[0018] When the coil is energized, the magnetic pole of the coil close to the magnet is the same as the magnetic pole of the magnet close to the coil, and the magnetic pole of the coil close to the magnet drives the first knob to move from the first position to the second position through the magnet.

[0019] The temperature controller provided in the present application includes a coil and a magnet, which can drive the first knob to move from a first position to a second position through the magnet when the coil is energized, so that the first knob and the first rotating shaft can be matched and then disengaged, and the first knob and the first rotating shaft can be disengaged when the temperature position is not adjusted, thereby avoiding the incorrect adjustment of the temperature position due to accidental contact of the first knob.

[0020] According to an embodiment of the present disclosure, pressing the first knob causes the first knob to move and the first knob moves from the second position to the first position, thereby enabling flexible switching of the first knob and the first rotating shaft between engagement and disengagement, thereby facilitating adjustment of the temperature level and avoiding misadjustment of the temperature level.

[0021] According to an embodiment of the present disclosure, the first rotating shaft has a rotating shaft first end and a rotating shaft second end which are arranged opposite to each other in the extending direction of the rotating shaft thereof;

[0029] a static contact connected to a power circuit of the compressor;

[0030] A moving contact connected to a power circuit of the compressor, wherein the moving contact moves so as to make the moving contact contact or separate from the static contact;

[0084] In this application, reference is made to Figure 1-Figure 2 The box body may include an inner liner 102. The inner liner 102 may be disposed in the outer shell 101. The inner liner 102 may be disposed in the outer shell accommodation space.

[0085] In this application, reference is made to Figure 1-Figure 2 An installation space 103 may be formed between the outer shell 101 and the inner shell 102 .

[0086] One end of the installation space 103 close to the box opening 12 is open.

[0087] In the present application, the box body 1 may include a box frame 104. The box frame 104 may be connected to the outer shell 101 and / or the inner liner 102. The box frame may be arranged at an opening of the installation space near one end of the box opening to cover the opening.

[0088] In the present application, a foam layer may be provided in the installation space 103 to insulate the storage room.

[0089] In the present application, the height direction of the box body is from the bottom end of the box body to the top end of the box body.

[0090] In the present application, the box body may have a left-right direction. The left-right direction of the box body may be from one side end of the box body to the other side end of the box body.

[0091] In the present application, the box body may have a front-to-back direction. The front side of the box body to the rear side of the box body may be the front-to-back direction of the box body.

[0092] In the present application, among the height direction, width direction and front-back direction of the box body, two of them are perpendicular.

[0095] In the present application, the refrigeration device may include a compressor 31. The compressor 31 is used to compress the refrigerant gas in a low-temperature and low-pressure state to discharge the refrigerant gas in a high-temperature and high-pressure state.

[0096] In the present application, the refrigeration device includes a condenser. The refrigerant gas discharged from the compressor flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0097] In the present application, the refrigeration device may include a throttling device, which can expand the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant.

[0098] In the present application, the refrigeration device may include an evaporator 32. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low temperature and low pressure state to the compressor. The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled.

[0099] In the present application, the refrigerant flows out of the compressor, sequentially flows through the condenser, the throttling device and the evaporator, and then flows back to the compressor to form a refrigerant circuit.

[0100] In the present application, the compressor 31 may be disposed in the installation space 103 .

[0101] In the present application, the evaporator 32 may be disposed in the installation space 103 .

[0102] In the present application, the evaporator 32 may be disposed in the inner container 102 .

[0103] In this application, reference is made to Figure 1-Figure 3 The refrigeration device may include a thermostat 4. The thermostat 4 may be connected to a power supply circuit of the compressor to control power on and power off of the compressor.

[0104] In the present application, the thermostat 4 can be used to adjust the temperature level of the storage room.

[0105] In the present application, the thermostat 4 may be in contact with the evaporator 32 .

[0106] In the present application, the thermostat 4 may be in contact with the inner tank 102 .

[0107] In the present application, the contact point between the thermostat and the inner tank may be located on a side of the inner tank close to the refrigeration tube of the evaporator.

[0108] In this application, reference is made to Figure 3-Figure 4 The thermostat may include a first rotating shaft 41. Rotating the first rotating shaft 41 may adjust the temperature level of the storage chamber.

[0109] In this application, reference is made to Figure 3-Figure 4 , the thermostat may include a first knob 43 .

[0110] In the present application, the first knob may have at least a first position.

[0111] In the present application, when the first knob is in the first position, the first knob 43 can cooperate with the first rotating shaft 41 .

[0112] In the present application, when the first knob cooperates with the first rotating shaft, rotating the first knob causes the first rotating shaft to rotate to adjust the temperature level of the storage chamber.

[0113] In the present application, the first knob may have at least a second position.

[0114] In the present application, when the first knob is in the second position, the first knob can be released from the first rotating shaft.

[0115] In the present application, when the first knob is released from the first rotating shaft, the first rotating shaft does not rotate when the first knob is rotated.

[0116] In this application, reference is made to Figure 4-Figure 6 The thermostat 4 may include a coil 42. The coil 42 may be wound around the first rotating shaft 41.

[0117] In this application, reference is made to Figure 4-Figure 6 The thermostat 4 may include a magnet 44. The magnet 44 may be connected to the first knob. The magnet may be at a certain distance from the first coil.

[0118] In the present application, when the coil is energized, the magnetic pole of the coil close to the magnet is the same as the magnetic pole of the magnet close to the coil, and the magnetic pole of the coil close to the magnet drives the first knob to move from the first position to the second position through the magnet.

[0119] In the present application, when the coil is energized, the magnetic poles generated by the coil drive the first knob to move through the magnet so that the first knob and the first rotating shaft are matched and then released from matching.

[0120] The temperature controller provided in the present application includes a coil and a magnet, which can drive the first knob to move from a first position to a second position through the magnet when the coil is energized, so that the first knob and the first rotating shaft can be matched and then disengaged, and the first knob and the first rotating shaft can be disengaged when the temperature position is not adjusted, thereby avoiding the incorrect adjustment of the temperature position due to accidental contact of the first knob.

[0121] In this application, reference is made to Figure 8When the coil is wound on the first rotating shaft along the first direction, the end of the coil close to the magnet can form an N pole. The end of the magnet close to the coil can be an N pole. The two N poles repel each other so that the magnet moves away from the coil, and the magnet drives the first knob to move from the first position to the second position.

[0122] In this application, reference is made to Figure 7 When the coil is wound on the first rotating shaft along the second direction, the end of the coil close to the magnet can form an S pole. The end of the magnet close to the coil can be an S pole. The two S poles repel each other so that the magnet moves away from the coil, and the magnet drives the first knob to move from the first position to the second position.

[0123] In the present application, the first direction and the second direction may be opposite.

[0124] In the present application, pressing the first knob causes the first knob to move and the first knob to move from the second position to the first position, which can achieve flexible switching of the first knob and the first rotating shaft in coordination and discoupling, facilitates the adjustment of the temperature level and avoids incorrect adjustment of the temperature level.

[0125] In the present application, pressing the first knob causes the first knob and the first rotating shaft to be released from engagement and become engaged with each other, thereby enabling flexible switching of the engagement and release of the first knob and the first rotating shaft, facilitating adjustment of the temperature level and avoiding misadjustment of the temperature level.

[0126] In this application, reference is made to Figure 4-Figure 6 The first rotating shaft 41 has a rotating shaft first end 411 and a rotating shaft second end which are arranged opposite to each other in the extending direction of the rotating axis of the first rotating shaft.

[0127] In the present application, the magnet 44 can be arranged on a side of the coil away from the second end of the rotating shaft, so as to facilitate the first knob to rotate under the action of the magnetic poles generated by the coil.

[0128] In the present application, when the first knob and the first rotating shaft cooperate, the first knob can be sleeved on the first rotating shaft by the first end of the rotating shaft, so that the first knob can drive the first rotating shaft to rotate.

[0129] In the present application, when the first knob and the first rotating shaft are released from engagement, the first knob can be sleeved on the first rotating shaft by the first end of the rotating shaft.

[0130] In the present application, when the first knob and the first rotating shaft are released from engagement, the first knob may be located on a side of the first end of the rotating shaft away from the second end of the rotating shaft.

[0131] In the present application, when the first knob moves from the first position to the second position, the first knob moves away from the second end of the rotating shaft.

[0132] In the present application, the magnet can be connected to one end of the first knob. The magnet can be located between the coil and the first knob to facilitate the connection between the magnet and the first knob.

[0133] In the present application, when the first knob and the first rotating shaft cooperate, the magnet can be sleeved on the first rotating shaft so that the magnet and the coil are as directly opposite as possible, so that the coil and the magnet can have a better mutual repulsion effect.

[0134] In the present application, when the first knob and the first rotating shaft are released from engagement, the magnet can be sleeved on the first rotating shaft.

[0135] In the present application, when the first knob and the first rotating shaft are released from engagement, the magnet may be located on a side of the first end of the rotating shaft away from the second end of the rotating shaft.

[0136] In this application, reference is made to Figure 4-Figure 6 The first rotating shaft is provided with a first matching portion 412. The first knob is provided with a second matching portion 433.

[0137] The first knob is matched with the first rotating shaft through the first matching portion and the second matching portion.

[0138] In the present application, the first matching portion may be a flat rod, the second matching portion may be a flat hole, and when the first knob and the first rotating shaft are matched, the flat rod may be inserted into the flat hole.

[0139] In the present application, when the first knob is in the first position, the minimum gap between the magnet and the coil is the first gap. The first gap is ≥0.5 mm. To avoid the first gap being too small, the magnet is located in the external magnetic field of the coil, and the magnetic pole of the coil close to one end of the magnet can drive the first knob from the first position to the second position through the magnet according to the principle that like poles repel each other.

[0140] In the present application, the first gap is ≤5mm, which prevents the first gap from being too large. The gap between the two is prevented from being too large, which makes the force between the magnet and the coil smaller, thereby ensuring the driving effect of the coil on the magnet and ensuring that the first knob can move from the first position to the second position.

[0141] In the present application, setting the first gap to 0.5mm≤1≤5mm can ensure that the first gap is within a reasonable range, which can produce mutual repulsion and ensure a certain driving force, thereby facilitating the matching and dismatching between the first knob and the first rotating shaft.

[0142] In this application, reference is made to Figure 4-Figure 6 The thermostat may include a thermostat housing 451. The thermostat housing 451 is used to protect the structure of the thermostat.

[0143] In the present application, the first rotating shaft may extend at least a certain distance out of the thermostat housing. The first end of the rotating shaft may be located outside the thermostat housing.

[0144] In the present application, the end of the coil close to the magnet can be located outside the thermostat housing. The magnet can be located outside the thermostat housing. The first knob can be located outside the thermostat housing.

[0145] In this application, reference is made to Figure 9-10 The housing may include a housing side plate 1011. The housing side plate may be disposed on a side of the housing.

[0146] In this application, reference is made to Figure 9-11 A first through hole 10111 may be formed on the shell side plate. The first through hole may penetrate the shell side plate in the thickness direction of the shell side plate.

[0147] In the present application, the box body may include a first fixing member 104. The first fixing member 104 is used to fix the thermostat.

[0148] In this application, reference is made to Figure 9-11 The first fixing member 104 may be connected to the side plate of the housing. The first fixing member 104 may be located in the first through hole.

[0152] In the present application, the second end of the first rotating shaft may be located in the installation space.

[0153] In the present application, the first end of the first rotating shaft may be located in the installation space.

[0154] In the present application, the first rotating shaft may be located in the knob through hole.

[0159] In the present application, when the first knob and the first rotating shaft cooperate, the rotating portion of the knob is located in the fixed groove.

[0160] In this application, reference is made to Figure 13-Figure 16 , the thermostat may include a stationary contact 461. The stationary contact may be stationary.

[0161] The stationary contact 461 may be connected to a power circuit of the compressor.

[0166] When the moving contact is separated from the static contact, the compressor is powered off. When the moving contact is in contact with the static contact, the compressor is powered on.

[0167] After the compressor is powered off, the compressor cannot be started to work. When the compressor is powered on, the compressor can be started to work.

[0168] In the present application, the moving contact may be located inside the thermostat housing.

[0169] In this application, reference is made to Figure 13-Figure 16 The temperature controller may include a first connecting rod 463. The first connecting rod may be connected to the moving contact. The movement of the first connecting rod drives the moving contact to move and contact or separate with the static contact.

[0170] In the present application, the moving contact may be provided at one end of the first connecting rod.

[0171] In the present application, the first connecting rod is configured to be swingable.

[0172] In the present application, the first connecting rod may be rotatably connected to the thermostat housing so that the first connecting rod may swing.

[0173] In the present application, the first connecting rod has a connecting rod first end and a connecting rod second section which are arranged opposite to each other in the length direction thereof.

[0174] In the present application, the moving contact may be arranged at the first end of the connecting rod. The second end of the connecting rod may be rotatably connected to the thermostat housing so that the first connecting rod may be swung.

[0175] In the present application, the first connecting rod may be located inside the thermostat housing.

[0176] In this application, reference is made to Figure 13-Figure 16 The temperature controller may include a temperature regulating cam 464. The temperature regulating cam may be connected to the first rotating shaft. The first rotating shaft drives the temperature regulating cam to rotate.

[0177] In the present application, the temperature adjustment cam may be located within the thermostat housing.

[0178] In the present application, the temperature adjustment cam may be located outside the thermostat housing.

[0179] In the present application, the thermostat may include a temperature control plate 465. The temperature control plate is in contact with the adjustment cam.

One end of the first elastic member 466 is connected to the temperature control plate. The other end of the first elastic member 466 is connected to the first connecting rod.

[0183] The first rotating shaft drives the temperature regulating cam to rotate, and the temperature regulating cam drives the first elastic member to extend or shorten through the temperature control plate to increase or decrease the tension of the first elastic member. The greater the tension of the first elastic member, the greater the tension overcome when the moving contact and the static contact come into contact.

[0184] In the present application, one end of the temperature control plate can be in contact with the outer peripheral wall of the adjustment cam. The temperature control plate is swingably arranged.

[0185] In the present application, the other end of the temperature control plate can be rotatably connected to the thermostat housing so that the temperature control plate can be swingably arranged.

[0186] In the present application, the connection point between the first elastic member and the temperature control plate is located between the swing center of the temperature control plate and the contact point between the temperature control plate and the adjusting cam.

[0187] In the present application, the connection between the first elastic member and the first connecting rod is located between the swing center of the first connecting rod and the connection between the first connecting rod and the moving contact.

[0188] In the present application, the first elastic member may be located inside the thermostat housing.

[0189] In this application, reference is made to Figure 13-Figure 16 , the thermostat may include a first adjusting member 467. The first adjusting member 467 may be connected between the first elastic member and the first connecting rod to adjust the tension of the first elastic member.

[0190] In the present application, the connection between the first adjusting member and the first connecting rod is located between the swing center of the first connecting rod and the connection between the first connecting rod and the moving contact.

[0191] In the present application, the first adjustment member may be located in the thermostat housing.

[0192] In this application, reference is made to Figure 13-Figure 16 , the thermostat may include a temperature sensing package 468 .

[0193] In the present application, the temperature sensing bulb 468 may be in contact with the evaporator to sense the temperature of the evaporator.

[0194] In the present application, the temperature sensing package 468 may be in contact with the inner container to sense the temperature of the inner container.

[0195] In this application, reference is made to Figure 13-Figure 16 A first temperature sensing agent space 4681 may be formed in the temperature sensing package. The first temperature sensing agent space may be filled with a temperature sensing agent.

[0196] In the present application, the temperature sensing agent can expand when heated and contract when cooled. The temperature sensing agent can be a refrigerant.

[0197] In the present application, the temperature sensing package may be located outside the thermostat housing.

[0198] In this application, reference is made to Figure 13-Figure 16 The temperature controller may include an air bag 470. A second temperature sensing agent space 4702 may be formed in the air bag.

[0199] In the present application, the first temperature sensing agent space may be communicated with the second temperature sensing agent space.

[0200] In the present application, the second temperature sensing agent space may be filled with a temperature sensing agent.

[0201] In this application, the gas bag can be located inside the thermostat housing.

[0202] In this application, reference is made to Figure 13-Figure 16 The temperature sensing agent may include a first top rod 471. One end of the first top rod may be connected to the air bag. The other end of the first top rod may be connected to the first connecting rod.

[0203] In the present application, the first push rod may be located inside the thermostat housing.

[0204] In the present application, the connection point between the first push rod and the first connecting rod is located between the swing center of the first connecting rod and the moving contact point.

[0205] In the present application, the connection point between the first push rod and the first connecting rod is located between the swing center of the first connecting rod and the connection point between the first adjusting member and the first connecting rod.

[0206] In the present application, when the temperature of the evaporator or the inner tank increases, the temperature sensed by the temperature sensing package will also increase. The thermal expansion of the temperature sensing agent in the temperature sensing package causes the pressure in the temperature sensing package to increase.

[0207] When the pressure in the temperature-sensing bag rises, the end of the air bag connected to the first push rod moves away from the end of the air bag away from the first push rod, so that the air bag drives the first push rod to move, and the first push rod drives the first connecting rod to move, that is, the temperature-sensing agent thermally expands so that the air bag drives the first connecting rod to move through the first push rod. The first connecting rod overcomes the pulling force of the first elastic member and drives the moving contact to move so that the moving contact contacts the static contact.

[0208] After the moving contact and the static contact are connected, the compressor is energized and can work, causing the temperature of the evaporator and the inner tank to decrease.

[0209] In the present application, when the temperature of the evaporator or the inner tank decreases, the temperature sensed by the temperature sensing package will also decrease. The temperature sensing agent in the temperature sensing package shrinks due to cooling, causing the pressure in the temperature sensing package to decrease.

[0210] When the pressure in the temperature-sensing bag drops, one end of the air bag connected to the first push rod approaches the end of the air bag away from the first push rod, so that the air bag drives the first push rod to move, and the first push rod drives the first connecting rod to move, that is, the temperature-sensing agent shrinks and causes the air bag to drive the first connecting rod to move through the first push rod.

[0211] Furthermore, the first connecting rod receives the pulling force of the first elastic member, the first elastic member pulls the first connecting rod, and the first connecting rod drives the moving contact to move so that the moving contact and the static contact are released from contact.

[0212] After the moving contact and the static contact are released from contact, the compressor is powered off and cannot work, and the temperature at the inner tank and the evaporator will rise.

[0213] In this application, reference is made to Figure 13-Figure 16 The air bag may include a diaphragm 4701. The diaphragm 4701 may be disposed at one end of the air bag close to the first push rod. The diaphragm may be connected to the first push rod. When the pressure in the air bag changes, the length of the air bag will change, and the diaphragm of the air bag will move. The diaphragm can drive the first push rod to move.

[0214] In this application, reference is made to Figure 13-Figure 16 The temperature controller may include a temperature sensing tube 472. A third temperature sensing agent space 4721 may be formed in the temperature sensing tube. The third temperature sensing agent space may connect the first temperature sensing agent space and the second temperature sensing agent space.

[0215] In the present application, one end of the temperature sensing tube connected to the air bag can be located inside the thermostat housing, and one end of the temperature sensing tube connected to the temperature sensing bag can extend outside the thermostat housing.

[0216] In the present application, the first rotating shaft will drive the adjusting cam to rotate when it rotates. When the radius of the contact point between the temperature control plate and the adjusting cam increases, the swing angle of the temperature control plate becomes larger, the first elastic member is pulled longer, the pulling force loaded on the first connecting rod is greater, and the greater the wind force that needs to be overcome when the moving contact contacts the static contact, the greater the pressure in the air bag needs to be, because the temperature felt by the temperature-sensing bag needs to be higher. Then, the larger the radius of the contact point between the adjusting cam and the temperature control plate, the higher the temperature of the storage room in the refrigeration equipment. The smaller the radius of the contact point between the adjusting cam and the temperature control plate, the lower the temperature of the storage room in the refrigeration equipment.
