Description
Technical Field
The present disclosure relates to storage devices, and particularly to a refrigerator with a storage device, a storage device and a control method thereof.
Background
In recent years, as the living standard of people is increasingly improved, the logistics industry is rapidly developed, so that fruits and vegetables (especially tropical fruits) can be conveniently and rapidly transported to various places. However, fruits and vegetables are difficult to preserve because they begin the process of post-ripening and decay immediately after picking and most are sensitive to the phytohormone ethylene.
In order to solve the problem, a fresh-keeping device with functions of removing ethylene and peculiar smell appears in the prior art, and the fresh-keeping device is matched with an activated carbon fiber filter with an ethylene adsorption function through a circulating fan to purify and cool air in the fresh-keeping device. Nevertheless, the prior art recycle blowers operate at a constant frequency, which has unavoidable drawbacks. On one hand, if the number of fruits and vegetables in the fresh-keeping device is large and the constant frequency of the circulating fan is relatively low, namely the air speed of the circulating fan is too low, the ethylene concentration of local areas such as the surfaces of the fruits and vegetables is easily too high, and therefore the rotting of parts of the fruits and vegetables is accelerated; on the other hand, if the number of fruits and vegetables in the fresh-keeping device is small and the constant frequency of the circulating fan is relatively high, that is, the air speed of the circulating fan is too high, the fruits and vegetables are easily dried and dehydrated.
In addition, since tropical fruits grow in a hot zone and cannot withstand low temperature, the temperature in the refrigerating chamber of a household refrigerator is usually set to be about 4 ℃ to 7 ℃, which is relatively low for tropical fruits, so that the taste of the tropical fruits is affected, even the tropical fruits are frozen, and the storage of the tropical fruits is not facilitated.

According to the control method of the storage device, the weight of the articles stored in the storage space of the storage device is firstly obtained, and then the fan is driven to operate, so that the airflow in the storage space is enabled to flow through the adsorption module and then return to the storage space. When the airflow flows through the adsorption module, part of ethylene and/or at least part of odor molecules contained in the airflow are adsorbed, so that the purposes of reducing the ethylene concentration and/or removing the odor are achieved. The larger the weight of the articles stored in the storage space is, the higher the ethylene concentration in the storage space is and the heavier the peculiar smell is; the smaller the weight of the articles stored in the storage space, the lower the ethylene concentration in the storage space may be and the lighter the odor may be. Therefore, the invention sets the operating frequency of the fan to be matched with the weight of the articles stored in the storage space. On one hand, if the weight of the articles stored in the storage space is larger, the fan runs at a relatively higher running frequency, so that the phenomenon that the concentration of ethylene and/or peculiar smell and the like in a local area in the storage space is too high due to too low running frequency of the fan can be avoided; on the other hand, if the weight of the articles stored in the storage space is smaller, the fan runs at a relatively lower running frequency, so that the fan can be prevented from running at an unnecessary higher frequency, the energy consumption is saved to a certain extent, and the phenomenon that the articles stored in the storage space are too dry due to overhigh running frequency of the fan and are air-dried and dehydrated can be avoided.

That is, the temperature in the storage space can be maintained between 10.5 ℃ and 13.5 ℃, and the tropical fruit can be kept cool without cold storage effect in the temperature range. Therefore, the storage device can provide a storage environment which is relatively low in temperature and convenient for fresh keeping for tropical fruits, and can keep good taste of fruits and vegetables such as the tropical fruits stored in the storage device, so that the use experience of a user is improved.

Detailed Description
Embodiments of the present invention provide a storage device that can be used alone or placed in a refrigeration device or other device having a particular storage environment. Fig. 1 is a schematic structural view of a storage apparatus according to an embodiment of the present invention, and referring to fig. 1, the storage apparatus 1 includes a main body portion 10, an adsorption module 20, and a blower 30. The main body portion 10 defines therein a storage space for storing articles and an air duct 13 communicating with the storage space. The adsorption module 20 is used to remove ethylene and/or odors from the air stream flowing therethrough. The fan 30 is used to promote the circulation of the air flow between the storage space and the air duct 13.
Specifically, in some embodiments of the present invention, the adsorption module 20 removes ethylene and/or odors in an adsorptive manner. The adsorption module 20 may be constructed of molecular sieves, activated carbon, or other materials having ethylene and/or odor adsorbing properties. Preferably, in one embodiment of the present invention, the adsorption module 20 may be composed of molecular sieves. Due to the difference in the pore size of the molecular sieve for adsorbing different gaseous substances, the pore size of the molecular sieve constituting the adsorption module 20 can be selected according to the kind of the article stored in the storage device 1. For example, in some embodiments of the present invention, when the stored articles in the storage device 1 are fruits and vegetables which are easy to produce a large amount of ethylene for ripening, the pore size of the molecular sieve constituting the adsorption module 20 can be selected such that the adsorption module 20 is specifically used for adsorbing ethylene, thereby preventing fresh fruits and vegetables stored in the storage space from rotting in a short period of time and prolonging the storage time of the fresh fruits and vegetables stored in the storage space. In other embodiments of the present invention, when the articles stored in the storage device 1 are meat, cooked food, pickled vegetables and other articles which are easy to generate odor and/or bad smell, the pore size of the molecular sieve constituting the adsorption module 20 may be selected such that the adsorption module 20 is specifically used for adsorbing odor and/or bad smell.
In particular, the storage device 1 further comprises a weight detection device 18 configured for detecting the weight of the items stored in the storage space. Specifically, the weight detecting device 18 may be a pressure sensor, an electronic scale, or other suitable device having a function of detecting weight. The fan 30 is configured to be controllably operated at an operating frequency that matches the weight of the items stored in the storage space to cause airflow in the storage space to return to the storage space through the air duct 13 after passing through the adsorption module 20.
In some embodiments of the present invention, the storage device 1 further includes a control device disposed inside the storage device 1 or outside the storage device 1, and the control device is configured to control the operation of the blower 30 and make the operation frequency match with the weight of the articles stored in the storage space. Specifically, when the storage device 1 is used alone, the control device may be an independent control circuit board integrated with a control circuit provided in the storage device 1. When the storage device 1 is placed in a refrigeration and freezing device or other devices with a specific storage environment, the control device may be an independent control circuit board integrated with a control circuit arranged in the storage device 1 or a main control board of the refrigeration and freezing device.
Specifically, the weight detecting device 18 acquires the weight of the articles stored in the storage space and generates a detection signal for indicating the weight of the articles stored in the storage space. The control device generates a corresponding control signal according to the detection signal, so as to drive the fan 30 to operate.
In some embodiments of the present invention, the body portion 10 further includes a drawer 11 defining a storage space and a box 12 for sealing the drawer. Specifically, the storage space of the storage device 1 is formed in the drawer 11. The air duct 13 is formed between the peripheral wall of the drawer 11 and the peripheral wall of the box body 12. That is, the duct 13 may include a gap between the upper opening 111 of the drawer 11 and the top plate 121 of the case 12, a gap between both sidewalls of the drawer 11 and both sidewalls of the case 12, and a gap between the rear wall 112 of the drawer 11 and the rear plate 122 of the case 12. The fan 30 may be disposed in the air duct 13 to promote the circulation of the air flow in the storage space and the air duct 13. In some embodiments of the present invention, the blower 30 may be disposed in the gap between the rear wall 112 of the drawer 11 and the rear plate 122 of the box 12, i.e., the blower 30 may be located outside the rear wall of the drawer 11 and inside the rear plate 122 of the box 12. In other embodiments of the present invention, the blower 30 may be disposed in a gap between two sidewalls of the drawer 11 and two sidewalls of the box 12.
In some embodiments of the present invention, the peripheral wall of the drawer 11 may be provided with a mounting portion for mounting the adsorption module 20, and the mounting portion may be a through hole opened in the peripheral wall of the drawer 11 or a through groove having an air hole, so that the air flow in the storage space is circulated to the air passage through the adsorption module. In an embodiment of the present invention, the mounting portion may be opened at the rear wall 112 of the drawer 11, that is, the adsorption module 20 is disposed at the rear wall 112 of the drawer 11. In other embodiments of the present invention, the adsorption module 20 may be disposed on other peripheral walls of the drawer 11 except for the rear wall 112 thereof, that is, the adsorption module 20 may be disposed on two side walls of the drawer 11.
Further, in an embodiment of the present invention, the air inlet of the fan 30 may be directly opposite to the adsorption module 20, so that the airflow passing through the adsorption module 20 almost completely flows to the air inlet of the fan 30 and returns to the storage space through the air duct 13 under the driving of the fan 30, and thus the airflow is installed to flow according to a fixed air path, thereby preventing the airflow from generating turbulence and mixing in the air duct 13, and accelerating the circulation flow of the airflow between the storage space and the air duct 13.
In some embodiments of the present invention, the storage device 1 further comprises a drawer state detection component configured to detect an open/close state of the drawer 11. The control means is also configured to stop the operation of the fan 30 when the drawer 11 is in the open state.
Specifically, the drawer state detecting means may be a laser sensor, a photosensor, a spring pressure switch, or other suitable means having a function of detecting the open/close state of the drawer 11. In some embodiments of the present invention, the drawer state detection member may be a laser sensor.
In some embodiments of the present invention, the storage device 1 further includes an air inlet 123 opened on the box 12 for selectively delivering cooling air flow into the storage space and/or the air duct 13, and a heating device 70 disposed at the bottom of the drawer 11. Specifically, the heating device 70 may be a resistance wire, a heating wire, a heater, or other suitable components having a heating function. The intake opening 123 may be opened at an upper portion of the rear wall 122 of the case 12.
The storage device 1 further comprises a temperature sensor arranged inside the storage space and configured to detect a current temperature inside the storage space of the storage device 1. Specifically, in some embodiments of the present invention, the temperature of the storage space of the storage device 1 may be set between a first preset temperature and a second preset temperature, that is, the first preset temperature is a lower limit temperature value of the storage space, and the second preset temperature is an upper limit temperature value of the storage space.
In some embodiments of the present invention, the control device is configured to close the air inlet 123 to prevent the cooling air flow from entering and activate the heating device 70 when the temperature in the storage space is lower than a first preset temperature. The control means is further configured to maintain the closed state of the air inlet 123 and stop the heating means 70 when the drawer 11 is in the open state.
The control device is further configured to open the air inlet 123 to allow the cooling air flow to enter and stop the heating device 70 when the temperature in the storage space is higher than a second preset temperature. The control means is further configured to close the air inlet 123 and maintain the stopped state of the heating means 70 when the drawer 11 is in the open state.
Further, the storage device 1 further includes an air outlet 125 opened on the box body 12 for selectively discharging warm air flow to the ambient space, an air inlet damper 124 for opening and/or closing the air inlet 123, and an air outlet damper 126 for opening and/or closing the air outlet 125. Specifically, in some embodiments of the present invention, the air outlet 125 may be opened at a lower portion of the rear wall 122 of the box 12, so that the air inlet 123 at the upper portion fills the storage space from top to bottom, and the warm air existing in the storage space is uniformly exhausted from the air outlet 125 at the lower portion, thereby achieving the exchange of air flow in the storage space.
The control device may generate a control signal to control the opening and/or closing of the intake damper 124, the opening and/or closing of the exhaust damper 126, and the activation and/or deactivation of the heating device 70, according to the current temperature in the storage device 1 detected by the sensor.
The embodiment of the invention also provides a control method of the storage device, which is suitable for controlling the storage device 1 in any one of the embodiments. Fig. 2 is a schematic flowchart of a control method of a storage device according to an embodiment of the present invention. The control method of the embodiment of the invention comprises the following steps:
s401, acquiring the weight of the articles stored in the storage space;
in step S402, the fan 30 is driven to operate at an operating frequency matched with the weight of the articles stored in the storage space, so as to promote the airflow in the storage space to flow through the adsorption module 20 and then return to the storage space through the air duct 13.
The control method of the storage device 1 of the invention firstly obtains the weight of the articles stored in the storage space of the storage device 1, and then drives the fan 30 to operate, so as to promote the airflow in the storage space to return to the storage space after flowing through the adsorption module 20. When the airflow passes through the adsorption module 20, part of the ethylene and/or at least part of the odor molecules contained in the airflow are adsorbed, so that the purpose of reducing the ethylene concentration and/or removing the odor is achieved.
Because the larger the weight of the articles stored in the storage space is, the higher the ethylene concentration in the storage space is and the heavier the peculiar smell is; the smaller the weight of the articles stored in the storage space, the lower the ethylene concentration in the storage space may be and the lighter the odor may be. Thus, the present invention sets the operating frequency of the blower 30 to match the weight of the items stored in the storage space. On one hand, if the weight of the articles stored in the storage space is large, the fan 30 operates at a relatively high operating frequency, so that the phenomenon that the concentration of ethylene and/or peculiar smell and the like in a local area in the storage space is too high due to too low operating frequency of the fan 30 can be avoided; on the other hand, if the weight of the articles stored in the storage space is smaller, the fan 30 operates at a relatively lower operating frequency, so that the fan 30 can be prevented from operating at an unnecessary higher frequency, energy consumption can be saved to a certain extent, and the problems that the articles stored in the storage space are too dry and the articles stored in the storage space are air-dried and dehydrated due to overhigh operating frequency of the fan 30 can be avoided.
Fig. 3 is a schematic flowchart of a control method of a storage device according to another embodiment of the present invention. In other embodiments of the present invention, after the operation of driving the fan 30 to operate at the operation frequency matched with the weight of the articles stored in the storage space, the control method of the storage device 1 further includes:
detecting the open/close state of the drawer 11; and
if the drawer 11 is in the open state, the operation of the fan 30 is stopped; if the drawer 11 is in the closed state, the operation of obtaining the weight of the articles stored in the storage space is performed in a return manner.
That is, in other embodiments of the present invention, a control method of the storage apparatus 1 includes:
step S501, acquiring the weight of the articles stored in the storage space;
step S502, the fan 30 is driven to operate at an operating frequency matched with the weight of the articles stored in the storage space, so that the airflow in the storage space is promoted to flow through the adsorption module 20 and then return to the storage space through the air duct 13;
step S503, detecting the open/close state of the drawer 11;
step S504, judge whether the drawer 11 is in the closed state; if the drawer 11 is in the closed state, go to step S501; if the drawer 11 is in the open state, go to step S505;
step S505, the operation of the fan 30 is stopped.
Fig. 4 is a schematic flowchart of a control method of a storage device according to still another embodiment of the present invention. In still other embodiments of the present invention, prior to the operation of obtaining the weight of the items stored in the storage space, the control method further includes:
detecting the open/close state of the drawer 11;
if the drawer 11 is in the closed state, the operation of obtaining the weight of the articles stored in the storage space is continuously performed.
That is, in still other embodiments of the present invention, a control method of the storage apparatus 1 includes:
step S601 of detecting an open/close state of the drawer 11;
step S602, judging whether the drawer 11 is in a closed state; if the drawer 11 is in the open state, go to step S601; if the drawer 11 is in the closed state, go to step S603;
step S603, obtaining the weight of the articles stored in the storage space;
in step S604, the fan 30 is driven to operate at an operating frequency matched with the weight of the articles stored in the storage space, so as to promote the airflow in the storage space to flow through the adsorption module 20 and then return to the storage space through the air duct 13.
Specifically, in some embodiments of the present invention, the open/closed state of the drawer 11 may be detected by a laser sensor, a photosensor, a spring pressure switch, or other suitable drawer state detecting means having a function of detecting the open/closed state of the drawer 11.
In some embodiments of the present invention, in the operation of acquiring the weight of the items stored in the storage space, the weight of the items stored in the storage space is acquired by a pressure sensor provided at the bottom of the drawer 11.
