Description

Technical Field

[0001] The present application relates to the technical field of household electrical appliances, for example, to a refrigeration device. Background Art

[0002] At present, more and more users use refrigeration equipment to store food. However, during use, the storage space in the refrigeration equipment cannot meet the needs of users.

[0003] In the related art, a horizontal evaporator is arranged at the bottom of the refrigeration equipment to reduce the space occupied by the evaporator, thereby increasing the storage space of the refrigeration equipment. When the refrigeration equipment is in operation, frost will form on the surface of the evaporator, resulting in a lower refrigeration rate. The evaporator is heated by a defrosting heating pipe arranged on the evaporator to achieve defrosting of the evaporator.

[0004] In the publicly available implementation process, the following problems were found in the relevant technology:

[0005] Although using a defrost heating tube to heat a horizontal evaporator can achieve defrosting of the evaporator, the heating area of ​​the heating tube is small, resulting in uneven heating of the evaporator surface, causing the evaporator to deform due to uneven temperature, reducing the life of the evaporator. In addition, the frost that falls and is not completely melted will block the drain port, affecting the discharge of defrost water.

[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0041] Combination Figures 1 to 6 As shown, an embodiment of the present disclosure provides a refrigeration device, including: an evaporator 101 and a heating plate assembly 20. The evaporator 101 is arranged in an evaporation chamber 102. The heating plate assembly 20 is arranged below the evaporator 101, or below the evaporator 101 and above the evaporator 101, and the heating plate assembly 20 has a preset angle with the horizontal direction.

[0042] The refrigeration device provided by the embodiment of the present disclosure is provided with a heating plate assembly 20 having a preset angle with the horizontal direction below the evaporator 101, so that the defrosting water and the frost ice that has not been completely melted can fall onto the heating plate assembly 20 during the defrosting process, so as to continue to heat the frost ice that has not been completely melted to melt it. This can reduce the accumulation of frost ice in the drain port, thereby reducing the problem of defrosting water blockage. At the same time, the heating plate assembly 20 increases the heating area of ​​the evaporator 101, reduces the deformation problem of the evaporator 101, and improves the service life of the evaporator 101.

[0043] Specifically, the heat radiation emitted by the heating plate assembly 20 can be irradiated onto the evaporator 101. When the heating plate assembly 20 is arranged below the evaporator 101, the heating plate assembly 20 is powered on to release heat radiation, and the heat radiation is irradiated onto the surface of the evaporator 101 located above the heating plate assembly 20, so as to transfer heat to the frost ice on the surface of the evaporator 101, thereby melting the frost ice, causing the frost ice to melt and fall off. Moreover, after the fallen frost ice that has not been completely melted falls onto the heating plate assembly 20, it can continue to be heated by the heating plate assembly 20 to be completely melted into defrost water. It is achieved to reduce the frost ice accumulated at the drain outlet, thereby reducing the problem of defrost water blockage. At the same time, since the heating plate assembly 20 has a preset angle with the horizontal direction, the defrost water that falls can flow downward along the inclined heating plate assembly 20, so that the defrost water flows to the drain outlet.

[0044] Furthermore, when the heating plate assembly 20 is disposed below and above the evaporator 101, the lower surface of the evaporator 101 is heated by the heating plate assembly 20 below the evaporator 101, and the upper surface of the evaporator 101 is heated by the heating plate assembly 20 above the evaporator 101, thereby achieving all-round heating of the evaporator 101 through the heating plate assembly 20. This improves the defrosting speed of the evaporator 101 and the practicality of the heating plate assembly 20.

[0045] Specifically, the heating plate assembly 20 is a plate-type heating with a larger heating area. Compared with the heating tube, the heating plate assembly 20 has a larger and more uniform heating function, improves the heating uniformity of the evaporator 101, reduces the deformation problem of the evaporator 101, and increases the service life of the evaporator 101.

[0046] Optionally, the refrigeration equipment provided by the embodiments of the present disclosure includes but is not limited to a refrigerator or a freezer.

[0047] Optionally, combined Figure 1 As shown, the preset angle ɑ is 6 degrees to 8 degrees.

[0048] In this embodiment, a preset angle is set so that defrost water can flow to the drain outlet along the heating plate assembly 20 which has a preset angle with the horizontal direction, thereby speeding up the drainage and reducing the problem of blockage of the drain outlet.

[0049] Optionally, combined Figure 1 , Figure 2 and Figure 3 As shown, when the heating plate assembly 20 is disposed below the evaporator 101 , the heating plate assembly 20 includes: a first heating plate 201 . The first heating plate 201 is disposed below the evaporator 101 .

[0050] In this embodiment, the first heating plate 201 is provided to achieve the arrangement of the heating plate assembly 20 below the evaporator 101 , so that the lower surface of the evaporator 101 can be heated by the first heating plate 201 to achieve defrosting of the evaporator 101 .

[0051] Specifically, the first heating plate 201 has a preset angle with the horizontal direction.

[0052] Specifically, the first heating plate 201 is powered on to release heat radiation, and the heat radiation is irradiated to the lower surface of the evaporator 101 located above the first heating plate 201, so as to transfer heat to the frost ice on the lower surface of the evaporator 101, thereby melting the frost ice, causing the frost ice to melt and fall off. Moreover, after the fallen frost ice that has not been completely melted falls on the first heating plate 201, it can continue to be heated by the heating plate assembly 20 to be completely melted into defrost water. It is achieved to reduce the frost ice accumulated in the drain port, thereby reducing the problem of defrost water blockage. At the same time, since the first heating plate 201 has a preset angle with the horizontal direction, the defrost water that falls can flow downward along the inclined first heating plate 201, so that the defrost water flows to the drain port.

[0053] Optionally, one end of the first heating plate 201 is located above the drain port. Or one end of the first heating plate 201 is located at the drain port. In this way, the defrost water can flow directly to the drain port, speeding up the discharge of the defrost water and reducing the problem of blockage of the drain port.

[0054] Optionally, combined Figure 2 and Figure 3 As shown, when the heating plate assembly 20 is disposed below the evaporator 101 and above the evaporator 101, the heating plate assembly 20 includes: a first heating plate 201 and a second heating plate 202. The first heating plate 201 is disposed below the evaporator 101. The second heating plate 202 is disposed above the evaporator 101.

[0055] In this embodiment, a first heating plate 201 is arranged below the evaporator 101, and a second heating plate 202 is arranged above the evaporator 101. The first heating plate 201 and the second heating plate 202 are powered on to release heat radiation. The first heating plate 201 is used to heat the lower surface of the evaporator 101, and the second heating plate 202 is used to heat the upper surface of the evaporator 101, so that the evaporator 101 is heated in all directions through the heating plate assembly 20. The defrosting speed of the evaporator 101 is increased, and the practicality of the heating plate assembly 20 is improved.

[0056] Furthermore, the first heating plate 201 below the evaporator 101 can continue to heat the incompletely melted frost ice that falls onto the first heating plate 201 to melt the frost ice and turn it into defrosting water, which then flows downward along the inclined first heating plate 201 to flow to the drain port.

[0057] Optionally, combined Figure 6 As shown, the heating plate assembly 20 further includes: a third heating plate 206 . The third heating plate 206 is disposed on a side of the evaporator 101 .

[0058] In this embodiment, by arranging the third heating plate 206 on one side of the evaporator 101 , the frost on the surface of the evaporator 101 is heated at a wider angle, thereby further accelerating the defrosting speed of the evaporator 101 .

[0059] Optionally, combined Figure 6 As shown, the heating plate assembly 20 further includes: a fourth heating plate 207 . The fourth heating plate 207 is disposed on the other side of the evaporator 101 .

[0060] In this embodiment, by arranging the fourth heating plate 207 on the other side of the evaporator 101 , the frost on the surface of the evaporator 101 is heated at a wider angle, thereby further accelerating the defrosting speed of the evaporator 101 .

[0061] Optionally, combined Figure 6 As shown, the heating plate assembly 20 further includes: a third heating plate 206 and a fourth heating plate 207. The third heating plate 206 and the fourth heating plate are located on two opposite sides of the evaporator 101, respectively.

[0062] In this embodiment, by arranging the third heating plate 206 and the fourth heating plate 207 on two opposite sides of the evaporator 101, the frost on the surface of the evaporator 101 is heated at a wider angle, thereby further accelerating the defrosting speed of the evaporator 101.

[0063] Optionally, combined Figure 1 , Figure 2 and Figure 3 As shown, when the evaporator 101 is a horizontal evaporator 101, the evaporator 101 has a preset angle with the horizontal direction. Wherein, when the heating plate assembly 20 includes a first heating plate 201, the first heating plate 201 is arranged parallel to the evaporator 101. When the heating plate assembly 20 includes a second heating plate 202, the second heating plate 202 is arranged parallel to the evaporator 101.

[0064] In this embodiment, the evaporator 101, the first heating plate 201 and the second heating plate 202 are arranged to be parallel to each other and to have a preset angle with the horizontal direction, so as to increase the heat radiation area of ​​the first heating plate 201 and the second heating plate 202 to the evaporator 101, thereby improving the defrosting speed. In addition, the evaporator 101 is arranged to have a preset angle with the horizontal direction, so that the frost on the evaporator 101 is separated from the evaporator 101 by heat and is easier to slide down by itself under the action of gravity, thereby improving the defrosting efficiency.

[0065] Specifically, when the evaporator 101 is a horizontal evaporator 101, the upper surface of the horizontal evaporator 101 has a large area. If the horizontal evaporator 101 is placed horizontally, it is not conducive for the frost on the upper surface of the horizontal evaporator 101 to melt and fall. By setting the preset angle, the frost on the upper surface of the horizontal evaporator 101 melts and slides down along the upper surface of the horizontal evaporator 101, thereby improving the defrosting efficiency.

[0066] Specifically, when the evaporator 101 is a horizontal evaporator 101, providing the first heating plate 201 and the second heating plate 202 can achieve more comprehensive heating of the frost on the horizontal evaporator 101, so as to accelerate the melting speed of the frost on the surface of the horizontal evaporator 101 and improve the defrosting efficiency.

[0067] Optionally, combined Figure 4 and Figure 5As shown, the heating plate assembly 20 includes: a heating plate. The heating plate includes: a housing 203, a conductive heating layer 204 and a conductive part. The housing 203 is configured with a heating cavity. The conductive heating layer 204 is arranged in the heating cavity. One end of the conductive part is conductively connected to the conductive heating layer 204, and the other end is used for an external power supply.

[0068] In this embodiment, the conductive heating layer 204 of the heating plate is energized so that the conductive heating layer 204 emits heat radiation, thereby achieving heating and defrosting of the evaporator 101 .

[0069] It can be understood that the structures of the first heating plate 201 and the second heating plate 202 are the same as the heating plates. For ease of understanding, the first heating plate 201 or the second heating plate 202 is not marked here.

[0070] Optionally, the conductive heating layer 204 includes a graphite film, a graphene film, a graphene coating or a conductive ink.

[0071] Optionally, the infrared radiation coefficient of the conductive heating layer 204 is greater than or equal to 0.89, which is beneficial for heat transfer through infrared radiation.

[0072] Optionally, combined Figure 5 As shown, the housing 203 includes a first plate 2031 and a second plate 2032 corresponding to both sides of the conductive heating layer 204. The first plate 2031 and the second plate 2032 are both capable of transmitting infrared rays. Alternatively, one of the first plate 2031 and the second plate 2032 is capable of transmitting infrared rays, and the plate capable of transmitting infrared rays faces the evaporator 101.

[0073] In this embodiment, the first plate 2031 and the second plate 2032 are both capable of transmitting infrared rays, so that heat can be emitted around the heating plate, so that the temperature in the entire evaporation chamber 102 can rise rapidly, thereby increasing the ambient temperature of the evaporator 101, thereby achieving heating and defrosting of frost on the surface of the evaporator 101.

[0074] By setting one of the first plate 2031 and the second plate 2032 to be able to transmit infrared rays, and the plate that can transmit infrared rays faces the evaporator 101, so that the plate facing the cavity wall of the evaporation chamber 102 cannot transmit infrared rays, the heat radiation emitted by the conductive heating layer 204 is reduced from irradiating the cavity wall of the evaporation chamber 102, so as to reduce the problem of heat damage to the cavity wall of the evaporation chamber 102.

[0075] Optionally, the edges of the first plate 2031 and the second plate 2032 are connected to form a heating chamber between the first plate 2031 and the second plate 2032. In this way, the insulation function and waterproof function of the heating plate can be achieved, and the safety of the heating plate can be improved.

[0076] Optionally, the first board body 2031 includes a first glass fiber board. The second board body 2032 includes a second glass fiber board.

[0077] Optionally, a reflective layer is provided on the wall of the evaporation chamber 102. The reflective layer can reflect the heat radiation emitted by the conductive heating layer 204. In this way, the heat radiation irradiated to the wall of the evaporation chamber 102 can be reflected into the evaporation chamber 102 through the reflective layer, thereby increasing the temperature in the evaporation chamber 102 to accelerate the heating and defrosting of the evaporator 101.

[0078] Optionally, combined Figure 4 As shown, the heating plate further includes: a mounting portion 205 . The mounting portion 205 is disposed at the edge of the housing 203 , and is used to be mounted below the evaporator 101 , or to be mounted above the evaporator 101 and below the evaporator 101 .

[0079] In this embodiment, the installation portion 205 is provided to realize the installation of the heating plate, and further realize the heating and defrosting of the evaporator 101 by using the heating plate.

[0080] Optionally, the refrigeration device further comprises: a screw. The mounting portion 205 comprises: a through hole. A threaded hole is provided on the wall of the evaporation chamber 102. The screw passes through the through hole and is matched with the threaded hole for connection.

[0081] In this embodiment, the heating plate is fixedly connected to the wall of the evaporation chamber 102 by screws to achieve installation of the heating plate, thereby achieving heating and defrosting of the evaporator 101 by the heating plate.

[0082] Exemplarily, in this case, one of the first plate 2031 and the second plate 2032 can be capable of transmitting infrared rays, and the plate capable of transmitting infrared rays faces the evaporator 101, so as to reduce the heat radiation emitted by the conductive heating layer 204 from irradiating the cavity wall of the evaporation cavity 102, so as to reduce the problem of heat damage to the cavity wall of the evaporation cavity 102.

[0083] Optionally, the refrigeration device further comprises: screws. The mounting portion 205 comprises: a bracket. A threaded hole is provided on the wall of the evaporation chamber 102. One end of the bracket is fixedly arranged on a plate surface, and the bracket and the plate surface have a certain angle. A through hole is provided on the other end of the bracket.

[0084] In this way, the screws pass through the through holes of the bracket and are connected to the threaded holes of the wall of the evaporation chamber 102 to achieve installation of the heating plate, thereby achieving heating and defrosting of the evaporator 101 by the heating plate.

[0085] By way of example, in this case, the solution that both the first plate 2031 and the second plate 2032 can transmit infrared rays can be adopted. Since the bracket has a certain length and the bracket and the plate surface connected to the bracket have a certain angle, the conductive heating layer 204 of the heating plate is at a certain distance from the cavity wall of the evaporation cavity 102. The heat radiation generated by the conductive heating layer 204 after power is turned on can be transferred to other positions in the evaporation cavity 102 through the position between the conductive heating layer 204 and the cavity wall of the evaporation cavity 102, so as to reduce the problem of heat damage to the cavity wall of the evaporation cavity 102.

[0086] Optionally, there is a gap between the heating plate assembly 20 and the evaporator 101 .

[0087] In this embodiment, a gap is provided between the heating plate assembly 20 and the evaporator 101 assembly to reduce the problem of excessively high temperature of the heat radiation emitted by the heating plate assembly 20 and large temperature variation of the evaporator 101, which may lead to damage to the evaporator 101.

[0088] Optionally, the spacing distance is 5 cm.

[0089] Optionally, the heating plate assembly 20 is in contact with the evaporator 101 .

[0090] In this embodiment, the heating plate assembly 20 and the evaporator 101 assembly are arranged in contact with each other, so as to achieve heating and defrosting of the evaporator 101 by contact heat conduction and radiation heat conduction, thereby improving the defrosting speed of the evaporator 101.

[0091] Optionally, the bottom cavity wall of the evaporation cavity 102 has a preset angle with the horizontal direction, and the heating plate disposed below the evaporator 101 is disposed on the bottom cavity wall of the evaporation cavity 102 .

[0092] In this embodiment, the heating plate (for example, the aforementioned first heating plate) below the evaporator 101 is arranged on the bottom wall of the evaporation chamber 102, so as to realize the installation of the heating plate below the evaporator 101. In addition, the bottom wall of the evaporation chamber 102 has a preset angle with the horizontal direction, so that the heating plate below the evaporator 101 has a preset angle with the horizontal direction, and then the defrost water flows along the heating plate to the drain port, thereby accelerating the discharge speed of the defrost water.

[0093] Optionally, the heating plate is spaced apart from or in contact with the bottom wall of the evaporation chamber 102 .

[0094] Optionally, the refrigeration device further includes: a thermostat. The thermostat includes a temperature sensing end and a temperature control end, and the temperature sensing end is arranged on the heating plate assembly 20 to detect the temperature of the heating plate assembly 20. The temperature control end is electrically connected to the heating plate assembly 20. The thermostat detects the temperature of the heating plate assembly 20, and controls the heating plate assembly 20 to stop heating when the detected temperature is greater than a preset temperature.

[0095] In this embodiment, a thermostat is provided to control the heating plate assembly 20 to stop heating when the temperature of the heating plate assembly 20 is too high, so as to reduce the problem of damage to the evaporator 101 caused by the over-high temperature of the heating plate assembly 20 and improve the practicality of the refrigeration device.

[0096] Optionally, the preset temperature is less than or equal to 80°C.
