Description

Technical Field

[0001] The present invention relates to the technical field of lockers, and more particularly to an intelligent temperature-controlled locker. Background Art

[0002] In the related technical solution, the intelligent temperature-controlled locker can achieve heat preservation and refrigeration of items through the combined use of semiconductor refrigerators and heating quartz tubes. Among them, the semiconductor refrigerator is embedded in the side panel of the locker, the cooling end is arranged in the storage cavity, and the heat dissipation end is arranged outside the storage cavity. When the locker needs to be heated and kept warm, the quartz tube is turned on and the semiconductor refrigerator is turned off. When the locker needs to be refrigerated, the quartz tube is turned off and the semiconductor refrigerator is turned on.

[0003] In order to omit the adaptation of the heating quartz tube, the inventor tried to set a rotatable semiconductor refrigerator on the side plate of the locker. The cooling end and the heat dissipation end of the semiconductor refrigerator intermittently align with the inner cavity of the locker, so that the locker can achieve the effects of refrigeration and heating and heat preservation at different times, thereby facilitating the realization of intelligent temperature control.

[0004] However, this technical solution is not convenient for achieving dehumidification and defrosting of the locker, and simply arranging a fan on the side panel of the locker will reduce the temperature control effect of the locker due to the existence of the ventilation channel. Summary of the invention

[0005] The purpose of the present invention is to overcome or at least alleviate the deficiencies of the above-mentioned prior art, so as to solve at least one of the above-mentioned technical problems.

[0006] In order to achieve the above-mentioned purpose, the present invention provides an intelligent temperature-controlled storage cabinet, including a cabinet body, which has a cabinet cavity, and a cabinet panel of the cabinet body is provided with an installation port that penetrates the cabinet body, and the installation port is filled with a semiconductor refrigerator, and the semiconductor refrigerator includes a base rotatably installed on the installation port, and the two sides of the base along the thickness direction of the base are respectively a cooling end and a heat dissipation end. Fans are slidably installed on the end faces of the cooling end and the heat dissipation end, respectively, and the rotation axis of the base is parallel to the first direction. The fan can slide and be fixed in a second direction perpendicular to the first direction, and the length of the fan along the second direction is not greater than half of the length of the base along the second direction; the semiconductor refrigerator has a cooling state, a heating state, and a ventilation state. The length dimension of the base along the second direction is greater than the farthest distance of the fans on the cooling end and the heat dissipation end along the thickness direction of the base.

[0007] In cooling state: the base rotates to block the installation opening, and the cooling end extends into the cabinet cavity, and the heat dissipation end is outside the cabinet. In heating state: the base rotates to block the installation opening, and the heat dissipation end extends into the cabinet cavity, and the cooling end is outside the cabinet. In ventilation state: the base rotates until the cooling end and the heat dissipation end are respectively aligned with the inner wall of the installation opening, and there is a ventilation gap between the cooling end and the heat dissipation end and the installation opening. The fan moves away from the cabinet cavity in the second direction until the fan is not facing the inner wall of the installation opening.

[0008] The beneficial effects of one or more of the above technical solutions are:

[0009] (1) The semiconductor refrigerator of this solution includes a base, which drives the entire semiconductor refrigerator to rotate in the installation opening of the storage cabinet, thereby making it easier for the entire semiconductor refrigerator to have a cooling state and a heating state. In the heating state, the heat dissipation end is in the cabinet cavity, the cooling end is outside the cabinet cavity, and the base blocks the installation opening. In the cooling state, the cooling end is in the cabinet cavity, the heat dissipation end is outside the cabinet cavity, and the base blocks the installation opening. That is, this solution can achieve heating, heat preservation and refrigeration of the entire storage cabinet using a single semiconductor refrigerator, which is convenient for adjusting the power of the semiconductor refrigerator according to needs, and intelligently realizing semiconductor temperature control.

[0010] (2) In this solution, fans are respectively arranged on the end faces of the cooling end and the heat dissipation end, and the fans can slide relative to the cooling end or the heat dissipation end connected thereto, and the sliding direction of the fans is a second direction perpendicular to the direction of the rotation axis of the base (i.e., the first direction). First, in the heating state and the cooling state, the fan can cause the heating airflow or the cooling airflow to flow fully in the cabinet cavity of the locker, thereby making the cabinet cavity of the locker evenly heated or cooled. Secondly, this enables the base of this solution to rotate until the locker has a ventilation state. In the ventilation state, the end faces of the cooling end and the heat dissipation end themselves have a gap with the inner wall of the mounting opening, and the fan can slide along the second direction until the air outlet is not facing the inner wall of the mounting opening (i.e., the fan slides in the mounting opening and is outside the cabinet body). At this time, the fan does not occupy the ventilation gap at the mounting opening, and the rotation of the fan facilitates the extraction of air from the mounting opening and the entire cabinet cavity, and discharges the extracted airflow in a direction away from the cabinet cavity. That is, this solution utilizes the way in which the fan can slide along the second direction to facilitate the ventilation, dehumidification, and defrosting processes of the locker.

DETAILED DESCRIPTION

[0021] The exemplary embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present invention, and are not intended to exhaust all possible modes of the present invention, nor to limit the scope of the present invention.

[0022] Reference Figure 1-Figure 9One or more embodiments of the present invention provide an intelligent temperature-controlled storage cabinet, including a cabinet body 3, which has a cabinet cavity, and a mounting port that penetrates the cabinet body 3 is provided at the cabinet plate of the cabinet body 3, and the mounting port is filled with a semiconductor refrigerator 2, and the semiconductor refrigerator 2 includes a base 4 that is rotatably mounted on the mounting port, and the two sides of the base 4 along the thickness direction of the base 4 are respectively a cooling end 6 and a heat dissipation end 8. Fans are slidably mounted on the end surfaces of the cooling end 6 and the heat dissipation end 8, respectively, and the rotation axis of the base 4 is parallel to the first direction, and the fan can slide and be fixed in a second direction perpendicular to the first direction, and the length of the fan along the second direction is not greater than half of the length of the base 4 along the second direction. The semiconductor refrigerator 2 has a cooling state, a heating state, and a ventilation state. In the cooling state: the base 4 rotates to block the mounting port, and the cooling end 6 extends into the cabinet cavity, and the heat dissipation end 8 is outside the cabinet body 3. In the heating state: the base 4 rotates to block the mounting port, and the heat dissipation end 8 extends into the cabinet cavity, and the cooling end 6 is outside the cabinet body 3. In the ventilation state: the base 4 rotates until the cooling end 6 and the heat dissipation end 8 are respectively aligned with the inner wall of the installation opening, and there is a ventilation gap 13 between the cooling end 6 and the heat dissipation end 8 and the installation opening. The fan moves away from the cabinet cavity in the second direction until the fan is not facing the inner wall of the installation opening.

[0023] In this embodiment, the length dimension of the base 4 along the second direction is greater than the farthest distance of the fans on the cooling end 6 and the heat dissipation end 8 along the thickness direction of the base 4. This arrangement facilitates that when the base 4 is rotated to the end faces of the cooling end 6 and the heat dissipation end 8 along the opening direction of the installation port, the end faces of the cooling end 6 and the heat dissipation end 8 can form a ventilation gap 13 with the inner wall of the installation port.

[0024] Specifically, the locker here is a square cabinet with a square cabinet cavity. Correspondingly, the cabinet door 1 is a square door. More specifically, the locker has three side panels, a top panel and a bottom panel, wherein the side panels are vertically arranged, and the top panel and the bottom panel are horizontally arranged; the cabinet door 1 is sealed at the cabinet opening of the locker. In order to achieve the sealing of the locker, a sealing strip is also provided between the side wall surface of the locker and the cabinet door 1, and the sealing strip is arranged around the cabinet door 1. More specifically, the sealing strip here is made of silicone or rubber material and can be set by technicians in this field. In addition, one end of the cabinet door 1 here can be rotatably connected to one side of the cabinet opening through a plurality of hinges arranged up and down.

[0025] Specifically, as mentioned above, the fan can slide and position in a second direction perpendicular to the first direction. It should be noted that, because the base 4 can rotate around its own central axis, the specific orientation of the second direction here will change with the rotation of the base 4, but it is always perpendicular to the first direction. More specifically, the first direction here is also perpendicular to the thickness direction of the base 4.

[0026] The length of the fan along the second direction mentioned above is not greater than one-half of the length of the base 4 along the second direction. This arrangement enables the base 4 to rotate to a point where half of the structure is located in the installation opening and the cabinet cavity of the cabinet 3, and the fan to move along the second direction to be basically located outside the cabinet 3, at which time the fan can still be supported by the end surface of the cooling end 6 or the heat dissipation end 8 of the semiconductor refrigerator 2. Preferably, the length of the fan along the second direction is equal to one-half or one-third of the length of the base 4 along the second direction.

[0027] In this embodiment, a rotation driving member is provided at the installation opening, and the rotation driving member is used to drive the base 4 to rotate around its own axis.

[0028] Specifically, the rotary drive member here adopts a driving motor 10 or a pneumatic motor, and the rotary drive member has a driving shaft 1001, and the driving shaft 1001 is coaxially fixed with the rotating shaft 401 on the base 4 through a coupling. The rotating shaft 401 here passes through the center point of the base 4. The rotating shaft 401 is fixed to the base 4, and the rotary drive member is fixedly embedded in the cabinet board of the cabinet body 3.

[0029] In this embodiment, the semiconductor refrigerator 2 includes a base 4 and a refrigerator body. The middle of the base 4 has a mounting cavity 402 that penetrates the base 4 along its thickness direction, and the refrigerator body is embedded in the mounting cavity 402 .

[0030] For details, see Fig. 9 , which gives a schematic diagram of the base 4 and the rotating shaft 401 in the top view. The base 4 has a mounting cavity 402 that runs through itself along its thickness direction (i.e., perpendicular to the first direction and the second direction). The mounting cavity 402 here is preferably arranged in a square shape to adapt to the square refrigerator body. The refrigerator body here can be fixed to the inner wall of the mounting cavity 402 by bolt connection or glue bonding. The refrigerator body completely fills the mounting cavity 402 to prevent heat from escaping along the mounting cavity 402.

[0031] In addition, in order to reduce the probability of airflow escaping from the gap between the mounting port and the semiconductor refrigerator 2, a sealing strip is provided at the mounting port of this embodiment, and the sealing strip is arranged around the inner wall surface of the mounting port. The sealing strip here can be elastically deformed to reduce its influence on the rotation of the base.

[0032] In this embodiment, two side surfaces of the base 4 along the second direction are first curved surfaces, and the inner wall of the installation opening has a second curved surface that fits the first curved surface.

[0033] Specifically, the installation opening in this embodiment is a square opening, and the square opening has four inner wall surfaces, two of which are opposite inner wall surfaces are planes, and the other two are arc surfaces, wherein the plane is perpendicular to the direction of the rotation axis of the base 4, and the arc surface is used to cooperate with the first arc surface and the second arc surface of the base 4 described below to realize the sealing of the installation opening by the base 4 in the heating state and the cooling state.

[0034] In this embodiment, the cooling end 6 and the heat dissipation end 8 are respectively provided with guide rods 7 along the second direction, and the fan is provided with guide holes for accommodating the guide rods 7 to pass through.

[0035] Specifically, two guide rods 7 are respectively provided on the end faces of the cooling end 6 and the heat dissipation end 8, and the two guide rods 7 arranged on the same end face can be arranged side by side. More specifically, support sections are respectively provided at both ends of the guide rod 7, and the support section ends are used to erect the guide rod 7 so that there is a gap between the body of the guide rod 7 and the end faces of the cooling end 6 and the heat dissipation end 8. The two ends of the guide rod 7 along the second direction extend to the outer boundary positions of the end faces of the cooling end 6 and the heat dissipation end 8, respectively, so that it can provide a longer sliding distance for the fan. In some other structural arrangements, three or four side-by-side guide rods 7 can also be provided at each end face, which can be arranged by technicians in this field.

[0036] Here, the fan at the cooling end 6 is a cooling fan 5, and the fan at the heat dissipation end 8 is a heat dissipation fan 9, and the two can slide independently along the second direction. In some other structural settings, they can also be set to slide synchronously. Specifically, the air outlet direction of the fan is perpendicular to the rotation axis of the base 4. That is, the air outlet direction of the fan is along the thickness direction of the base 4.

[0037] In this embodiment, a linear driving member is provided on one side of the fan, and the linear driving member is used to drive the fan to slide and position along the second direction.

[0038] As one of the specific structural forms, the linear drive assembly in this embodiment includes a spring and an electromagnet assembly, the spring is used to provide an elastic force to move the fan away from the cabinet cavity, and the electromagnet assembly is used to provide a magnetic force to move the fan toward the cabinet cavity.

[0039] For details, see Figure 6, the spring and the electromagnet assembly are respectively arranged on both sides of the fan along the second direction. One end of the spring is fixed to the fan, and the other end is fixed to the edge of the cooling end 6 or the heat dissipation end 8. The first electromagnet 11 of the electromagnet assembly is fixed to the fan, and the second electromagnet 12 is fixed to the end face of the cooling end 6 or the heat dissipation end 8. When the semiconductor refrigerator 2 is in a heating state or a cooling state: the first electromagnet 11 and the second electromagnet 12 are magnetically attracted (at this time, the spring is stretched and elastic potential energy is accumulated) so that the fan is at the center position of the end face of the cooling end 6 or the heat dissipation end 8, so as to realize the rapid delivery of hot air or cold air through the rotation of the fan. When in the ventilation state, in order to reduce the obstruction of the fan to the ventilation gap 13, and to use the fan to realize the drainage of the airflow in the installation port and the cabinet 3, the electromagnet assembly is powered off, and the tension of the spring causes the fan to move along the second direction toward the edge of the cooling end 6 or the heat dissipation end 8 along the second direction.

[0040] In some other structural arrangements, the linear drive assembly here can be replaced with a miniature electric push rod or a miniature linear motor, and the fan is driven to move along the second direction by the electric push rod or the linear motor.

[0041] In this embodiment, there are multiple installation openings, at least one of which is disposed on the top plate of the cabinet 3 , and at least one of which is disposed on the bottom of the side plate of the cabinet 3 .

[0042] See also Figure 1 A mounting port and a semiconductor refrigerator 2 are provided at the top plate of the cabinet 3 , and another mounting port and a corresponding semiconductor refrigerator 2 are provided at the bottom of the right side plate of the cabinet 3 .

[0043] In this arrangement, it is convenient to utilize two installation openings that are far apart to form a better heating, cooling or ventilation effect in the cabinet cavity of the cabinet body 3, so that the heat and airflow are more evenly distributed.

[0044] In this embodiment, a controller is further included, and the controller is used to control the rotation of the base 4 and the sliding of the fan along the second direction. A temperature sensor is arranged in the cabinet cavity of the locker, and the controller can obtain data of the temperature sensor and adjust the power of the semiconductor refrigerator 2.

[0045] Specifically, the controller can be one or more of an ARM processor, a single-chip microcomputer or a PLC controller. It is known that after the temperature required to be maintained in the locker is input to the controller, the controller can automatically determine whether to use the semiconductor refrigerator 2 for heating or cooling according to the current temperature value in the locker, and then control the rotation and positioning of the base 4, and facilitate the control of the power of the semiconductor refrigerator 2 to achieve intelligent temperature control of the locker.

[0046] Working principle: When the device is needed, it is determined whether the current locker needs to be in a cooling state, a heating state or a ventilation state, and then the base 4 is controlled to rotate and the fan is controlled to slide along the second direction so that the positions of the semiconductor refrigerator 2 and the fan meet the requirements. Then the semiconductor refrigerator 2 is powered on to keep it in the corresponding working state.

[0047] Of course, the present invention is not limited to the above-mentioned embodiments. Those skilled in the art may make various combinations and modifications to the above-mentioned embodiments of the present invention under the guidance of the present invention without departing from the scope of the present invention.
