The appliance compartment 10 is provided with a refrigeration system 11 and a control panel 12. The refrigeration system 11 includes a heat sink 111, a semiconductor cooler 112, a heat conductive member 113, and a partition 116. The semiconductor cooler 112 is electrically connected to the control board 12. The operating principle of the semiconductor cooler 112 is: by utilizing the Peltier effect, a pair of thermocouples is formed by N, P type semiconductor materials, and after the thermocouples pass through direct current, heat absorption and heat release phenomena can be generated at nodes of the thermocouples due to different directions of the direct current, wherein the phenomena are the Peltier effect. The semiconductor cooler 112 is made of N, P type semiconductor material. When current is applied, the temperature of the junction decreases as electrons pass from the P-type semiconductor through the junction to the N-type semiconductor; as electrons pass from the N-type semiconductor through the junction to the P-type semiconductor, the temperature of the junction increases. Therefore, one end of the semiconductor cooler 112 is a low temperature end, and the other end is a high temperature end.

The semiconductor cooler 112 has a high temperature end thermally coupled to the heat sink 111 and a low temperature end thermally coupled to the thermal conductive member 113. The low temperature end is used for absorbing heat of the refrigerating chamber 20 to cool the refrigerating chamber 20, and the high temperature end is used for releasing the heat absorbed by the low temperature end to the external environment. Since the high temperature end has a small size and a limited heat dissipation area, it is not able to satisfy the heat dissipation requirement, and therefore, the heat of the high temperature end needs to be dissipated to the external environment by the heat sink 111. The high-temperature end is in heat conduction connection with the radiator 111, and heat is conducted to the radiator 111, so that the heat dissipation effect of the high-temperature end of the semiconductor refrigerator 112 is improved, heat accumulation of the high-temperature end is reduced, the refrigeration effect of the semiconductor refrigerator 112 is improved, and the service life of the semiconductor refrigerator is prolonged. The heat sink 111 has a plurality of heat dissipating fins 1112 arranged in parallel, and the plane of the heat dissipating fins 1112 is parallel to the front panel 44, so that a gap for air circulation is formed between adjacent heat dissipating fins 1112.

Since the semiconductor cooler 112 has a plate structure, a heat conducting structure needs to be connected to the low temperature end to improve the heat absorption effect. The low temperature end is connected with a heat conducting member 113 in a heat conducting manner, and the heat conducting member 113 is a heat conducting structure of the semiconductor refrigerator 112. When the refrigerator 1000 is in an operating state, the low temperature end of the semiconductor refrigerator 112 exchanges heat with air in the refrigerating compartment 20 through the heat conductive member 113 to absorb heat in the refrigerating compartment 20. By passing a continuous current to the semiconductor cooler 112, the interior environment of the refrigerated compartment 20 can be controlled at a lower temperature.

Heat conductive materials are disposed between the high temperature end of the semiconductor cooler 112 and the heat sink 111 and between the low temperature end and the heat conductive member 113. The heat conduction material can be a product with high heat conduction coefficient, such as heat conduction silica gel, heat conduction silicone grease or a soft silica gel heat conduction pad. The heat conductive material may increase the degree of thermal coupling between the contact surface of the high temperature end and the heat sink 111 and the contact surface of the low temperature end and the heat conductive member 113, thereby more effectively transferring the heat of the low temperature end to the high temperature end. The heat conduction member 113 can realize the transfer of the cooling energy to the refrigerating compartment 20, and meanwhile, the heat conduction member 113 also has a cold storage function. The heat conducting material is a heat conducting compound and is also an insulator, so that the risk of short circuit of the circuit can be avoided. In some embodiments, the heat conducting member 113 is an aluminum block or a copper block, and the aluminum block and the copper block have both advantages of superior heat conductivity and light weight.

The semiconductor refrigerator 112 is driven by a dc power source, and the control board 12 converts an ac voltage of 220V into a dc voltage of 12V, 24V, or 3V-48V to supply power to the semiconductor refrigerator 112. The semiconductor cooler 112 determines a high temperature side and a low temperature side by changing the polarity of the dc current.

In some embodiments, the thickness of the semiconductor cooler 112 and the thickness of the spacer 116 may be equal. The partition 116 may separate heat of the heat sink 111 and the heat conductive member 113 to prevent heat exchange and heat convection between the heat sink 111 and the heat conductive member 113, thereby preventing the temperature of the refrigerating compartment 20 from being affected by the heat sink 111. One side of the partition plate 116 facing the electric appliance chamber 10 is in contact with the radiator 111, and one side of the partition plate 116 facing away from the electric appliance chamber 10 is in contact with the top cover shell 421 of the inner container cover 42, so that the structure is more compact, excessive occupation of the space of the electric appliance chamber 10 in the longitudinal direction is avoided, meanwhile, the heat conducting piece 113 is prevented from being in contact with the air of the electric appliance chamber 10, and a good heat insulation effect is achieved.

Since the heat conductive member 113 is disposed in the turn 421b of the top cover case 421 and its size is limited, a cooler 114 may be installed to improve the cooling effect of the refrigerating chamber 20.

Since the refrigerator 1000 is a micro-miniature thin-wall refrigerator, the arrangement of the cold diffuser 114 can be omitted under the condition that the requirement on the refrigeration effect is not high, that is, whether the cold diffuser 114 is arranged or not is determined according to the specific situation.

Therefore, when the refrigerating fan 115 is rotated, the air in the refrigerating chamber 20 is moved faster, and the temperature uniformity of the refrigerating chamber 20 is improved.

The diameter of the fan blade 141 is increased to reduce the rotation speed of the cooling fan 14 during operation, so that the noise of the cooling fan 14 is reduced on the premise of maintaining the air suction effect. Since the suction effect of the heat dissipation fan 14 is proportional to the diameter of the fan blade 141 and the rotation speed of the heat dissipation fan 14 during operation. The noise generated by the cooling fan 14 during operation is proportional to the rotation speed, i.e. the faster the rotation speed, the greater the noise. On the premise of maintaining the air suction effect of the heat dissipation fan 14, the larger the diameter of the fan blade 141 is, the lower the required rotation speed is, and the less noise is generated.

In some embodiments, the number of the fan blades 141 should be set to be odd, if the number of the fan blades 141 is even, resonance is easily caused due to symmetry, when there is a shake of one fan blade 141, the other fan blade 141 is also shaken, so that the balance of the fan blade 141 itself is difficult to adjust, and noise is increased; if the number of the fan blades 141 is odd, although there is a shaking phenomenon, resonance is not caused, so that balance of the fan blades 141 during operation is ensured, and noise is reduced, and therefore, the number of the fan blades 141 should be set to be odd, and the number of the fan blades 141 should be 3, 5, or 7.

When the actual temperature T1 is equal to the preset temperature T, the control panel 12 activates the alarm device to give an alarm to remind the user to take out the object 90 to be heated, and after the alarm device gives the alarm, the blower 13 is operated in the non-heating mode to cool the radiator 111, thereby protecting the semiconductor refrigerator 112 and the object 90 to be heated.

The second through hole 44b corresponds to the notch 80a of the heating slot 80b, that is, the notch 80a of the heating slot 80b faces the front panel 44 and the notch 80a of the heating slot 80b is disposed in the same direction as the opening of the refrigerating compartment 20. After the object 90 to be heated is taken out of the refrigerating compartment 20, the object is put into the heating groove 80b from the notch 80a, and the heating mode is performed. The operation panel 441 corresponds to the control board 12, and the operation panel 441 is disposed on a side of the front panel 44 opposite to the control board 12, so that the operation panel 441 is electrically connected to the control board 12. The operating panel 441 is located close to the control board 12, so that long-distance wire drawing is avoided, and the wiring difficulty is reduced. Meanwhile, the loss of the control panel 12 is reduced, excessive heat generation of the control panel 12 is avoided, the stability of the electric connection between the operation panel 441 and the control panel 12 is ensured, and the risk of accidental coupling caused by electromagnetic interference is avoided to a certain extent.

In some embodiments, the edge of the slot 80a abuts against the front panel 44, which ensures the sealing property between the appliance chamber 10 and the heating mechanism 80, wherein the abutting means includes, but is not limited to, riveting, welding, bonding, magnetic absorption, and the like. The side of the heat sink 111 close to the front panel 44 is in contact with the front panel 44, and a heat insulating material may be filled between the heat sink 111 and the front panel 44. One side of the heat sink 111 close to the front panel 44 and the edge of the notch 80a are both connected to the front panel 44, so that the heating slot 80b can only be communicated with the outside through the notch 80a and cannot be communicated with the electrical apparatus chamber 10, and the heat exchange between the heating slot 80b and the air outlet 40b and the air inlet 40a is avoided to a certain extent, thereby improving the heat preservation effect of the heating slot 80 b. Therefore, the external air flowing in from the air inlet 40a cannot be discharged from the hot slot 80a, and the high-temperature air inside the electric appliance chamber 10 is prevented from flowing out from the slot 80a under the action of the fan, so that the problem that the high-temperature air flow inside the electric appliance chamber 10 flows out from the slot 80a and then diffuses towards the human body when the door body 50 is opened is avoided, the damage to the human body is caused, and the heat dissipation effect of the refrigerator 1000, the cooling effect of the refrigerating chamber 20 and the heat preservation effect of the heating mechanism 80 are further guaranteed.

In some embodiments, the object 90 to be heated is placed in the heating groove 80b from the notch 80a, the object 90 to be heated is thermally conductive-connected to the second bottom plate 1113 by its own weight, and the second bottom plate 1113 transfers heat to the object 90 to be heated, thereby raising the temperature of the object 90 to be heated. The object 90 to be heated is heated by using the temperature of the second bottom plate 1113, and a heater is not additionally arranged, so that the heating device has the advantages of space saving, resource saving, energy saving, environmental protection and the like. Since the notch 80a is disposed on the same side as the opening of the refrigerating compartment 20, the user can take out the object 90 to be heated from the refrigerating compartment 20, immediately transfer the object to be heated to the heating mechanism 80, adjust the operation panel 441 to open the heating mode, and finally cover the door 50 on the cabinet 500. After the door 50 is closed, the heating groove 80b may be sealed by the attraction of the first and second

magnetic attraction members

442 and 442. The structural arrangement of the heating mechanism 80 makes the process of taking out the object 90 to be heated from the refrigerating compartment 20 and transferring to the heating mechanism 80 for heating easier.

The side of the front panel 44 facing the refrigerating compartment 20 has a first magnetic attraction piece 442 arranged along the circumference of the inner container 21, and a second magnetic attraction piece matched with the first magnetic attraction piece 442 of the front panel 44 is embedded in the door seal 51. After the door 50 is covered on the cabinet 500, the first magnetic attraction piece 442 attracts the second magnetic attraction piece to seal the refrigerating chamber 20. Therefore, after the refrigerator 1000 starts the heating mode and closes the door 50, the low-temperature airflow in the refrigerating chamber 20 cannot overflow from the opening of the refrigerating chamber 20, and heat exchange between the heating groove 80b and the refrigerating chamber 20 is avoided. The heating mechanism 80 and the refrigerating chamber 20 work independently without mutual interference, the heat source of the heating mechanism 80 comes from the high-temperature end of the semiconductor refrigerator 112, the cold source of the refrigerating chamber 20 comes from the low-temperature end of the semiconductor refrigerator 112, and the refrigerator has multiple purposes, so that the structure is more compact, the available space of the refrigerator 1000 is saved, and the resource waste is avoided.
