Description
Technical Field
The utility model belongs to the technical field of refrigeration equipment, and particularly provides a refrigerator.
Background
Some refrigerators are currently equipped with an air conditioning compartment and an air conditioning device such that the air conditioning device reduces or increases the oxygen content in the air conditioning compartment.
Existing air conditioning devices generally include a vessel defining a reaction chamber, a cathode disposed at an opening of the reaction chamber, an anode disposed within the reaction chamber, and an electrolyte filled within the reaction chamber. The air conditioning device is contacted with air in the low-oxygen space through the cathode, so that the oxygen undergoes a reduction reaction at the cathode, namely: o (O) 2 +2H 2 O+4e - →4OH - . And the anode is subjected to oxidation reaction, and oxygen is generated, namely: 4OH - →O 2 +2H 2 O+4e - 。
It follows that the air conditioning device essentially transfers oxygen from one side to the other. Therefore, in order to increase the oxygen utilization rate, some refrigerators are simultaneously configured with a low-oxygen chamber and a high-oxygen chamber, so that the air conditioner consumes oxygen in the low-oxygen chamber through an electrochemical reaction and transmits the generated oxygen to the high-oxygen chamber.
However, in the refrigerator using process, the regulation and control needs of the low-oxygen compartment and the high-oxygen compartment are often not synchronous, so that the oxygen content in the low-oxygen compartment or the high-oxygen compartment does not meet the actual fresh-keeping requirement.
Disclosure of Invention
The utility model aims to solve the problem that the oxygen content in the low-oxygen compartment or the high-oxygen compartment in the existing refrigerator does not meet the actual fresh-keeping requirement because the regulation and control requirements of the low-oxygen compartment and the high-oxygen compartment are often different.
It is a further object of the present utility model to provide a means for rapidly introducing oxygen from an oxygen buffer into a first high oxygen compartment.
A further object of the utility model is to ensure that the oxygen buffer is full of oxygen.
In order to achieve the above object, the present utility model provides a new refrigerator including:
a tank defining a hypoxic chamber and a first hypoxic chamber;

Optionally, the box body further defines a second high oxygen chamber, and a second gas pipe and a second gas return pipe are connected in series between the second high oxygen chamber and the oxygen buffer, so that gas can circulate between the second high oxygen chamber and the oxygen buffer by means of the second gas pipe and the second gas return pipe.
Optionally, the second high-oxygen chamber is configured with a second fan, one end of the second air pipe, which is communicated with the second high-oxygen chamber, is located at an air suction side of the second fan, and one end of the second air return pipe, which is communicated with the second high-oxygen chamber, is located at an air blowing side of the second fan.
Optionally, the refrigerator further includes a gas delivery control valve fluidly connected to the oxygen buffer, and the first gas delivery pipe and the second gas delivery pipe are respectively connected to the gas delivery control valve, so that the gas delivery control valve controls the gas flowing out of the oxygen buffer to flow to one or both of the first gas delivery pipe and the second gas delivery pipe.
Optionally, the refrigerator further includes an air return control valve fluidly connected to the oxygen buffer, and the first air return pipe and the second air return pipe are respectively connected to the air return control valve, so that the air return control valve controls one or both of the first high oxygen compartment and the second high oxygen compartment to return to the oxygen buffer.

Optionally, the oxygen buffer is configured with an exhaust control valve.
Optionally, the refrigerator further comprises a liquid supplementing container and a liquid supplementing pump, wherein the liquid supplementing pump is used for conveying liquid in the liquid supplementing container to the air conditioning device.

Therefore, the utility model solves the problem that the oxygen content in the low-oxygen compartment or the high-oxygen compartment in the existing refrigerator does not meet the actual fresh-keeping requirement because the regulation and control requirements of the low-oxygen compartment and the high-oxygen compartment are often different.
Further, the first fan is configured for the first high-oxygen chamber, one end, communicated with the first high-oxygen chamber, of the first gas pipe is located on the suction side of the first fan, one end, communicated with the first high-oxygen chamber, of the first gas return pipe is located on the blowing side of the first fan, and when the first fan rotates, air can be driven to circularly flow between the first high-oxygen chamber and the oxygen buffer through the first gas pipe and the first gas return pipe, so that oxygen in the oxygen buffer can rapidly enter the first high-oxygen chamber.
Further, by configuring the exhaust control valve for the oxygen buffer, when the oxygen content of the low-oxygen chamber needs to be reduced and the first high-oxygen chamber does not need to be increased, oxygen generated by the air conditioning device can continuously enter the oxygen buffer, and excessive gas in the oxygen buffer is discharged to the outside, so that the oxygen content of the gas in the oxygen buffer is higher and higher until the oxygen content is almost unchanged. At this time, the oxygen buffer may be considered to be full of oxygen.

As shown in fig. 3, in some embodiments of the present utility model, the refrigerator further includes an oxygen buffer 410, and the oxygen buffer 410 is used to buffer oxygen. As can be seen in fig. 3, oxygen exiting from the air conditioning device 200 needs to pass through the oxygen buffer 410 to enter the first high oxygen compartment 121 and/or the second high oxygen compartment 122.
With continued reference to fig. 3, a first gas pipe 511 and a first gas return pipe 512 are connected in series between the first high-oxygen chamber 121 and the oxygen buffer 410, so that gas circulates between the first high-oxygen chamber 121 and the oxygen buffer 410 via the first gas pipe 511 and the first gas return pipe 512.
Further, the first high oxygen compartment 121 is provided with a first fan 610. One end of the first air pipe 511, which is communicated with the first high-oxygen chamber 121, is located at the air suction side of the first fan 610, and one end of the first air return pipe 512, which is communicated with the first high-oxygen chamber 121, is located at the air blowing side of the first fan 610.
As will be appreciated by those skilled in the art, under the action of the first fan 610, air can circulate between the first high oxygen compartment 121 and the oxygen buffer 410 by means of the first air pipe 511 and the first air return pipe 512, so that oxygen in the oxygen buffer 410 rapidly enters the first high oxygen compartment 121, and the oxygen content in the first high oxygen compartment 121 is rapidly increased.
With continued reference to fig. 3, a second gas line 521 and a second gas return line 522 are connected in series between the second high oxygen chamber 122 and the oxygen buffer 410 such that gas circulates between the second high oxygen chamber 122 and the oxygen buffer 410 via the second gas line 521 and the second gas return line 522.

As will be appreciated by those skilled in the art, under the action of the second fan 620, air can circulate between the second high oxygen compartment 122 and the oxygen buffer 410 via the second air delivery pipe 521 and the second air return pipe 522, so that oxygen in the oxygen buffer 410 rapidly enters the second high oxygen compartment 122, and the oxygen content in the second high oxygen compartment 122 is rapidly increased.
With continued reference to FIG. 3, in some embodiments of the utility model, the refrigerator further includes a gas delivery control valve 710 fluidly connected to the oxygen buffer 410. The first gas pipe 511 and the second gas pipe 521 are respectively connected to the gas delivery control valve 710 such that the gas delivery control valve 710 controls the flow of gas from the oxygen buffer 410 to one or both of the first gas pipe 511 and the second gas pipe 521.
With continued reference to fig. 3, in some embodiments of the utility model, the refrigerator further includes a return air control valve 720 in fluid communication with the oxygen buffer 410. The first and second return air pipes 512 and 522 are connected to the return air control valve 720, respectively, such that the return air control valve 720 controls one or both of the first and second high oxygen chambers 121 and 122 to return air to the oxygen buffer 410.
Further, the ends of the gas transmission control valve 710 and the gas return control valve 720 near the oxygen buffer 410 may be respectively connected with the oxygen buffer 410 through pipelines.
With continued reference to FIG. 3, in some embodiments of the utility model, the oxygen buffer 410 is a container having a cavity, and the oxygen buffer 410 is configured with an exhaust control valve 420.
The exhaust control valve 420 may be an electrically controlled valve to be opened when oxygen is not required in both the first and second high oxygen chambers 121 and 122, and to be closed when oxygen is required in both the first and/or second high oxygen chambers 121 and 122. The vent control valve 420 may also be a one-way valve to automatically open when the pressure within the oxygen buffer container is high.
In some embodiments of the utility model, the gas delivery control valve 710 and the return gas control valve 720 may be three-position three-way solenoid valves. The refrigerator includes the following air conditioning modes:
in the oxygen-down mode of the hypoxic chamber 110, the gas delivery control valve 710 and the return gas control valve 720 are both closed, so that neither the first and second hypoxic chambers 121, 122 are in communication with the oxygen buffer 410. When the air conditioning apparatus 200 is powered on, oxygen in the hypoxic chamber 110 is consumed by the cathode membrane module 220. Oxygen exiting the air conditioning device 200 enters the oxygen buffer 410. Excess gas within the oxygen buffer 410 is vented to the external environment through a vent control valve 420. As the air conditioning apparatus 200 is continuously energized, the oxygen content of the gas in the oxygen buffer 410 increases until the oxygen content is almost unchanged. At this time, the oxygen buffer 410 may be considered to be full of oxygen.
The first high oxygen chamber 121 is in oxygenation mode such that the gas line control valve 710 communicates the oxygen buffer 410 with the first gas line 511 and the return gas control valve 720 communicates with the first return gas line 512. The first fan 610 is started, and air circulates between the first high-oxygen compartment 121 and the oxygen buffer 410 under the action of the first fan 610, so that oxygen in the oxygen buffer 410 rapidly enters the first high-oxygen compartment 121, and the oxygen content in the first high-oxygen compartment 121 is rapidly increased. During this process, if the oxygen content in the first high oxygen compartment 121 increases by a set value, the first blower 610 may be controlled to stop.
The second high oxygen chamber 122 is in oxygenation mode, with the gas transfer control valve 710 communicating the oxygen buffer 410 with the second gas transfer line 521, and the return air control valve 720 communicating the oxygen buffer 410 with the second gas transfer line 521. The second fan 620 is started, and under the action of the second fan 620, air circulates between the second high-oxygen compartment 122 and the oxygen buffer 410, so that oxygen in the oxygen buffer 410 rapidly enters the second high-oxygen compartment 122, and the oxygen content in the second high-oxygen compartment 122 is rapidly increased. During this process, if the oxygen content in the second high oxygen compartment 122 increases by a set value, the second blower 620 may be controlled to stall.
The simultaneous oxygenation mode of the first and second high oxygen compartments 121, 122 causes the gas transfer control valve 710 to communicate the oxygen buffer 410 with the first and second gas transfer pipes 511, 521, respectively, and to close the return gas control valve 720. The first fan 610 and the second fan 620 are activated.
The low oxygen chamber 110 and the first high oxygen chamber 121 simultaneously control the oxygen mode, and the air regulating device 200 is energized, so that the air delivery control valve 710 communicates the oxygen buffer 410 with the first air delivery pipe 511, and the return air control valve 720 communicates with the first return air pipe 512. At the same time, the first fan 610 may also be started.
The low oxygen chamber 110 and the second high oxygen chamber 122 simultaneously control the oxygen mode, and the air regulating device 200 is energized, so that the air delivery control valve 710 communicates the oxygen buffer 410 with the second air delivery pipe 521, and the return air control valve 720 communicates the oxygen buffer 410 with the second air delivery pipe 521. At the same time, the second fan 620 may also be activated.
The low oxygen chamber 110, the first high oxygen chamber 121 and the second high oxygen chamber 122 simultaneously control the oxygen mode, and the air regulating device 200 is electrified, so that the air delivery control valve 710 communicates the oxygen buffer 410 with the first air delivery pipe 511 and the second air delivery pipe 521 respectively. At the same time, the first fan 610 and the second fan 620 may also be activated.
Based on the foregoing description, it can be appreciated by those skilled in the art that the problem that the oxygen content in the low-oxygen compartment or the high-oxygen compartment in the existing refrigerator does not meet the actual fresh-keeping requirement due to the fact that the low-oxygen compartment and the high-oxygen compartment in the existing refrigerator are often different in regulation and control needs is solved.
Furthermore, in other embodiments of the present utility model, one skilled in the art may omit the placement of the refill container 310 and the refill pump 320 as desired.
