Detailed Description

Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following examples do not represent all embodiments consistent with the present application. But merely as exemplifications of systems and methods consistent with certain aspects of the application, as recited in the claims.

The semiconductor refrigerator is an electronic refrigerator which refrigerates through a semiconductor refrigerating sheet, the volume of the semiconductor refrigerating sheet is far smaller than that of a compressor, and therefore the semiconductor refrigerator is often applied to the field of small-size refrigerators. The small-sized refrigerator has a small volume, so that an excessive number of semiconductor cooling fins cannot be provided in the refrigerator, resulting in that the temperature of each region of the cooling compartment in the semiconductor refrigerator cannot be maintained uniformly.

In order to equalize the temperature of each area of the refrigerating chamber, part of the refrigerators also adopt an air duct to guide the cold energy produced by the semiconductor refrigerating sheet to the area with higher temperature. But the cold is directed via the duct to an area, which after a certain time may have caused the temperature in this area to be too low. The temperature of the refrigerating chamber can not be kept consistent, thereby reducing the refrigerating efficiency of the refrigerator.

In order to solve the above problems, referring to fig. 1, the present application provides a wall-mounted refrigerator capable of automatically switching an air path, comprising: main control board 100, refrigeration fan 200, semiconductor refrigeration piece 400, wind channel mechanism 500 and box 600, wherein:

the main control board 100 is disposed on the box body 600, and the refrigeration fan 200, the semiconductor refrigeration sheet 400 and the air duct mechanism 500 are disposed in the box body 600.

The semiconductor cooling plate 400 is also called a thermoelectric cooling plate, and is a heat pump. The Peltier effect of semiconductor materials can be utilized, when direct current passes through a galvanic couple formed by connecting two different semiconductor materials in series, heat can be absorbed and released at two ends of the galvanic couple respectively, and the aim of refrigeration is fulfilled. The semiconductor chilling plate 400 has the advantages of no sliding parts and is often applied to occasions where space is limited, reliability requirements are high and the semiconductor chilling plate cannot be polluted by refrigerants. The two ends of the semiconductor chilling plate 400 are provided with a heat dissipation block 401 and a cold dissipation block 402, the heat dissipation block 401 is arranged at one end of the semiconductor chilling plate 400 which emits heat, and the cold dissipation block 402 is arranged at one end of the semiconductor chilling plate 400 which absorbs heat.

The heat dissipation block 401 and the cold dissipation block 402 are usually made of aluminum, which has high heat conduction efficiency and can accelerate heat dissipation and cold dissipation at two ends of the semiconductor chilling plate 400. A cooling chamber 601, a heat radiation chamber 602, and a refrigerating chamber 603 are provided in the cabinet 600. The heat dissipation block 401 is disposed in the heat dissipation chamber 602, and the cold dissipation block 402 and the cooling fan 200 are disposed in the cooling chamber 601. The heat dissipation chamber 602 is generally in communication with the air outside the refrigerator, and a heat dissipation fan is also disposed in the heat dissipation chamber 602. Negative pressure is formed by the heat dissipation fan, and air outside the refrigerator is sucked into the heat dissipation chamber 602 and flows through the heat dissipation chamber 602. In the process, the heat on the heat dissipation block 401 can also flow out of the refrigerator along with the air, so that the heat dissipation of the heat dissipation block 401 is accelerated. After the heat dissipation block 402 absorbs the heat, the temperature of the air around the heat dissipation block 402 is lowered, and the cooling fan 200 blows the cool air around the heat dissipation block 402 to form a cooling air path. The refrigerating fan 200 and the semiconductor refrigerating sheet 400 are electrically connected with the main control panel 100. Referring to fig. 7, the main control board 100 includes both a control circuit and a receiving circuit, and the main control board 100 may receive a set command through the receiving circuit and control each element in the box 600 through the control circuit. Therefore, the main control board 100 can change the working states of the cooling fan 200 and the semiconductor cooling fins 400. For example: after the adjustment command is set, the main control board 100 may adjust the rotation speed of the refrigeration fan 200 or may turn on or off the refrigeration fan 200 and the semiconductor chilling plates 400. After the cooling fan 200 blows the cool air around the cooling block 402 to form a cooling air path, the cooling air path needs to be guided to the refrigerating chamber 603 to form a circulation air path for cooling. In the embodiment of the present application, the air duct mechanism 500 is used to guide the stroke of the cooling air duct. The air duct mechanism 500 is provided on an inner wall of the case 600.

In some embodiments, referring to fig. 5, the inner wall of the box 600 is provided with a groove 604 and a guide post 605. The guide posts 605 are disposed at the edges of the recess 604. When the air duct mechanism 500 is installed, the air duct mechanism 500 is placed in the groove 604, and the groove 604 plays a role in positioning, so that the air duct mechanism 500 is more convenient to install. And the guide posts 605 at the edge of the groove 604 can temporarily fix the air duct mechanism 500 at the position of the groove 604 to assist the installation of the air duct mechanism 500, thereby facilitating the installation and the disassembly of the air duct mechanism 500.

The air duct mechanism 500 includes an air duct 501 and a damper 502. The air duct 501 includes an air inlet 503 and an air outlet 504. The air inlet 503 is communicated with the refrigeration chamber 601, the air outlet 504 is communicated with the refrigeration chamber 603, and the number of the air outlets 504 is greater than or equal to two. The damper 502 is disposed in the air duct 501, and the damper 502 is electrically connected to the main control board 100, so that the main control board 100 can control the opening and closing of the damper 502. For example, all arrows in fig. 1 indicate the stroke of the cooling air path when the damper 502 is in the open state. When the dampers 502 in fig. 1 are both open, the semiconductor chilling plate 400 starts to operate, and then cool air is generated around the heat dissipation block 401. The cooling fan 200 sucks air in the refrigerating compartment 603 into the cooling compartment 601 through the air inlet 503, and forms a cooling air path in a direction indicated by an arrow in the air duct 501. After passing through the cooling block 402, the cooling air path drives the cooling air around the cooling block 401 to circulate together, and the cooling air flows into the refrigerating chamber 603 from the air outlet 504, so that the cooling air continuously circulates in the cooling chamber 601 and the refrigerating chamber 603 in the cooling air path in the direction indicated by the arrow, and the purpose of cooling is achieved.

When the damper 502 is closed, the cooling air path of the damper 502 is blocked at the damper 502. For example, when the damper 502 at position a in fig. 1 is closed, the cooling air path indicated by the dashed arrow in fig. 1 is blocked, i.e., the cooling air path stroke indicated by the dashed arrow does not exist. When the cooling air passage of the broken-line arrow portion is blocked, the cool air does not flow in a concentrated manner on the stroke of the cooling air passage of the broken-line arrow portion, and the temperature of the region of refrigerating room 603 corresponding to the stroke increases.

In some embodiments, a plurality of temperature sensors 631 are also disposed within the refrigerated compartment 603. The temperature sensor 631 is a sensor that senses temperature and converts it into a usable output signal. The temperature sensors 631 are respectively provided at different positions within the refrigerating compartment 603 so that temperatures in respective regions in the refrigerating compartment 603 can be detected. The temperature sensor 631 is electrically connected to the main control board 100, and may transmit a detected temperature signal to the main control board 100. The main control board 100 can selectively open or close the damper 502 corresponding to each zone according to the temperature of each zone, so as to adjust the temperature of each zone. Referring to fig. 2, all arrows in fig. 2 indicate the stroke of the cooling air path when the damper 502 is in the open state. The number of the semiconductor chilling plates 400 is also multiple, and a plurality of the semiconductor chilling plates 400 are connected in parallel, and each semiconductor chilling plate 400 can work independently. When the refrigerating capacity of one semiconductor refrigerating sheet 400 does not meet the requirement of the refrigerating chamber 603, a plurality of semiconductor refrigerating sheets 400 can be arranged in one refrigerating chamber 603 for refrigerating. When the main control board 100 controls the opening and closing of the dampers 502, the main control board may also adjust the temperature of each area in the refrigerating chamber 603 in cooperation with opening or closing the corresponding semiconductor chilling plates 400.

For example: when the damper 502 in the position B in fig. 2 is closed, the remaining dampers 502 are open, and only the top semiconductor chilling plate 400 is open, the temperature sensor 631 detects that the temperature of the arrow stroke area at the lowermost layer of the refrigeration chamber 603 in fig. 2 is high. To lower the temperature of the lowermost arrowhead travel zone of the refrigeration compartment 603, the main control panel 100 controls the damper 502 to open at position B in fig. 2. After the damper 502 at the position B is opened for a preset time period, the temperature sensor 631 detects that the temperature of the arrow stroke area at the bottommost layer is still not reduced to the expected temperature, the main control board 100 opens the semiconductor chilling plate 400 at the position B, and the semiconductor chilling plate 400 at the position B starts chilling, so that the chilling air volume is increased, and the speed of reducing the temperature of the arrow stroke area at the bottommost layer can be increased. Wherein, the preset time period can be freely set according to the actual conditions, such as: set to 5 minutes, 10 minutes, etc.

During the opening and closing of the damper 502, there may be a problem with the damper 502 not being fully closed. That is, the main control board 100 has controlled to close the damper 502, but due to factors such as jamming of the transmission mechanism in the damper 502, the damper 502 is not closed sufficiently, and a gap exists between the damper and the air duct 501. The cooling air will continue to circulate through the gap, resulting in an undesirable temperature regulation effect.

Therefore, referring to fig. 4, a pressure sensor 521 is further disposed on the damper 502, and the pressure sensor 521 is electrically connected to the main control board 100. A shutter 511 is provided in the air duct 501, and the shutter 511 is configured to contact the pressure sensor 521 when the damper 502 is closed. Pressure sensor 521, also known as a pressure transmitter, is a sensor that converts pressure into an analog electrical signal. For example, a strain gauge type pressure sensor is configured such that a strain gauge is physically deformed to convert pressure into an electric signal, and the strain gauge is bonded to a diaphragm of the pressure sensor and connected to form a wheatstone bridge structure. When the diaphragm is subjected to an externally applied pressure, the diaphragm is deflected to generate corresponding deformation, and the resistance value of the strain gauge is changed correspondingly in a manner related to the pressure. The pressure sensor 521 in the embodiment of the present application is used to detect the pressure between the damper 502 and the baffle 511. After the main control board 100 controls to close the damper 502, whether the pressure between the damper 502 and the flapper 511 reaches a preset pressure threshold is detected by the pressure sensor 521. For example: in practical applications, it is measured that the pressure value of the damper 502 is 0.5N when the contact with the baffle 511 is sufficient. After the main control board 100 closes the damper 502, if the pressure sensor 521 detects whether the pressure between the damper 502 and the baffle 511 is 0.1N, it is verified that the damper 502 and the baffle 511 are not in close contact with each other, and it is possible to determine whether the damper 502 is sufficiently closed.

When it is determined that the damper 502 is not sufficiently closed, the main control board 100 may issue a close command again to control the re-closing of the damper 502. After the damper 502 is re-closed, the pressure between the damper 502 and the baffle 511 continues to be detected by the pressure sensor 521, thereby detecting whether the damper 502 is sufficiently closed. After several attempts to re-close the damper 502, if the pressure between the damper 502 and the baffle 511 is still lower than the predetermined pressure threshold, an error message may be reported to prompt the user to perform maintenance. Namely, in some embodiments, an alarm module 101 is further disposed in the main control board 100. The alarm module 101 is configured to generate an alarm signal when the pressure is lower than a preset pressure threshold. The alarm module 101 may be connected to a speaker, a warning light, a buzzer, etc. The user is reminded that the air door 502 is not fully closed through the modes of sound signals, light signals and the like, so that the fault of the air door 502 can be checked in time. For example: the damper 502 may be re-opened and re-closed by the main control panel 100 after the user receives the alarm signal. If the alarm signal is not asserted to indicate that the damper 502 is sufficiently closed, the damper 502 may not be sufficiently closed without servicing due to other minor effects such as voltage instability. If the damper 502 is still not sufficiently closed, then servicing of the refrigerator is required.

In some embodiments, a distance sensor 522 is further disposed on the baffle 511. The distance sensor 522 is electrically connected to the main control board 100. The distance sensor 522 is used to detect the distance between the baffle 511 and the damper 502, and an optical distance sensor, an infrared distance sensor, an ultrasonic distance sensor, and the like may be used. The main control board 100 can control the opening and closing angle of the damper 502 according to the distance between the baffle 511 and the damper 502, thereby adjusting the temperature of each zone in the refrigerating compartment 603. The greater the angle at which the damper 502 is opened, the greater the amount of cooling air passing through the air duct 501 at the position of the damper 502, and the lower the temperature of the corresponding zone.

In some embodiments, since the refrigerator in the embodiments of the present application is a size refrigerator, it may be fixed on a vertical plane so as to reduce an occupancy rate of a horizontal storage space. Therefore, referring to fig. 5, the refrigerator further includes a fixing assembly 300, and the fixing assembly 300 is disposed at an outer wall of the cabinet 600. The fixing assembly 300 may employ an expansion screw, a rubber plate, etc., so that the refrigerator may be fixed on a wall, reducing an occupancy rate of a planar storage space.

In some embodiments of the present application, referring to fig. 6, the box 600 is provided with a first magnetic assembly 606 inside, and the outer wall of the wind tunnel 501 is provided with a second magnetic assembly 512. The first magnetic component 606 and the second magnetic component 512 are two components capable of generating magnetic attraction with each other. For example: the first magnetic component 606 is made of a magnet, and the second magnetic component 512 is made of an iron sheet; or the first magnetic component 606 is made of iron sheets, and the second magnetic component 512 is made of magnets; or the first magnetic component 606 adopts a magnet, and the second magnetic component 512 also adopts a magnet, but the magnetic poles corresponding to the contact parts of the first magnetic component 606 and the second magnetic component 512 are different. The air duct 501 is fixed in the box 600 by the magnetic attraction of the first magnetic component 606 and the second magnetic component 512. When needing to dismantle wind channel 501, can directly take out wind channel 501 from the inside of box 600, it is more convenient.

A damper 502 is disposed in the duct branch to block air flow from the outlet opening 504 when the damper 502 is closed. Through the plurality of air duct branches, different air duct branches in one air duct mechanism 500 can be arranged in different refrigerating chambers 603 to refrigerate the plurality of refrigerating chambers 603. The temperature of each region of each refrigerating chamber 603 is adjusted by controlling the opening and closing of the dampers 502 in the different duct branches. The temperature adjustment process of the control damper 502 is the same as the above principle, and is not described herein.

In some embodiments, a filter screen 513 is further disposed in the air duct 501, a degerming assembly 514 is disposed on the filter screen 513, and the filter screen 513 is disposed in the air duct 501.

The medium in the degerming module 514 may be ultraviolet light, photocatalyst, ozone, etc., and the above media may be combined or separately disposed in the degerming module 514.
