[0048] In the description of the present utility model, multiple means two or more. If there is a description of first, second, it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or implicitly indicating the sequence of indicated technical features.

[0049] In the description of the present utility model, unless otherwise explicitly limited, the words such as setting, installing, connecting, etc. should be interpreted broadly, and the person skilled in the art can reasonably determine the specific meaning of the above words in the present utility model according to the specific content of the technical scheme.

[0050] In the related art, the current ripening technology mainly uses ethephon to ripen fruits, and ethephon usually needs to be combined with high temperature treatment to achieve ripening in a refrigerator, which is relatively complex. Moreover, the ripening of ethephon is prone to cause over-ripening of fruits due to improper control of the addition amount, and the fruits that have been ripened cannot be consumed in time, and even in the low-temperature environment of the refrigerator, they are also prone to further over-ripening and corruption.

[0051] To this end, the application provides a refrigeration equipment, which can be a refrigerator or a freezer.

[0052] Please refer to Figure 1 and Figure 2 The refrigeration equipment 10 includes a cabinet 100, a first storage box assembly 200, and a second storage box assembly 300. The cabinet 100 is provided with a refrigeration chamber 110, and the first storage box assembly 200 and the second storage box assembly 300 are arranged in the refrigeration chamber 110.

[0053] The first storage box assembly 200 is provided with a first storage space 211, and the first storage box assembly 200 includes a ripening device 220 arranged in the first storage space 211. The ripening device 220 is configured to ripen fruits and vegetables in the first storage space 211 by a physical method. By arranging the ripening device 220 in the first storage space 211, the first storage space 211 is a ripening space, and fruits and vegetables with low maturity can be stored in the first storage space 211. The ripening device 220 is used for ripening and can accelerate the ripening speed of fruits and vegetables and promote the ripening of fruits and vegetables. The ripening device 220 can use light, vibration, or other physical methods to promote the ripening of fruits and vegetables.

[0054] The second storage box assembly 300 is provided with a second storage space 311, and the second storage box assembly 300 includes a ripening device 320 arranged in the second storage space 311. The ripening device 320 is used to inhibit the ripening of fruits and vegetables in the second storage space 311. By arranging the ripening device 320 in the second storage space 311, the second storage space 311 is a ripening space, and fruits and vegetables with high maturity can be stored in the second storage space 311. The ripening device 320 is used for ripening and can slow down the ripening speed of fruits and vegetables during storage and prevent fruits and vegetables from further over-ripening and corruption. In particular, fruits that have been ripened by the ripening device 220 in the first storage space 211 can be stored in the second storage space 311 when the user cannot consume them in a short period of time, thereby avoiding over-ripening of the fruits due to the user's inability to consume them as soon as possible. The ripening device 320 can use physical and / or chemical methods to inhibit the ripening of fruits and vegetables. For example, in a chemical method, the ripening device 320 can release an ethylene inhibitor to inhibit the production of ethylene by fruits and vegetables, thereby slowing down the ripening of fruits and vegetables.

[0055] Therefore, by arranging the ripening device 220 in the first storage space 211 and the maturation inhibiting device 320 in the second storage space 311, the refrigeration equipment has both the ripening function and the maturation inhibiting function, which can improve the maturity of fruits and vegetables and prevent the fruits and vegetables from over-ripening, and can meet the needs of users.

[0056] It should be further noted that ethylene generally needs to be combined with high temperature to ripen fruits (ethylene can only play a good ripening effect in a high-temperature environment of 20 DEG C or above), however, a high-temperature environment can accelerate the respiration and transpiration of fruits, accelerate the consumption of nutrients and the loss of water of fruits, affect the preservation of fruits, and high temperature is easy to cause fruits to be infected with bacteria and rot.

[0057] The ripening device 220 of the present application adopts a physical ripening method, and compared with the chemical ripening method using ethylene, the ripening device 220 does not need to be limited by high-temperature conditions, and therefore, the ripening device 220 can be arranged in a low-temperature environment to ripen fruits and vegetables. In this embodiment, the ripening device 220 is further configured to ripen at a first temperature, the first temperature is greater than the temperature of the refrigeration chamber 110, and the first temperature is greater than or equal to 12 DEG C and less than or equal to 15 DEG C.

[0058] The environment of 12 DEG C-15 DEG C is a low-temperature environment, and by arranging the first storage space 211 at this temperature during the ripening process, the low temperature can reduce the respiration and transpiration of fruits, slow down the loss of nutrients and water in fruits, and be beneficial to the preservation of fruits. In addition, the lower temperature can inhibit the reproduction of bacteria and reduce the risk of fruits being infected with bacteria and rotting during the ripening process. Moreover, the temperature of 12 DEG C-15 DEG C is not too low, and is suitable for the preservation of most fruits, especially tropical fruits. Please refer to Figure 3 , 12 DEG C-15 DEG C is the best storage temperature for most tropical fruits, and can avoid the occurrence of cold damage of tropical fruits.

[0059] Please refer to Figures 4 to 6 , the applicant of the present application conducted ripening experiments on bananas, mangoes and avocados in environments of 4 DEG C (low temperature), 12 DEG C (low temperature) and 25 DEG C (high temperature) respectively, and obtained Figures 4 to 6The appearance change diagram of each group of fruits in the ripening process is shown. As can be seen from the figure, after ripening at a high temperature environment of 25℃, although the bananas, mangoes and avocados all show high maturity, large dark patches appear on the surface of the bananas (over-ripe, prone to internal blackening and rotting), the mangoes show obvious anthracnose, and the avocados show no problems on the surface, but the internal flesh of the avocados can be clearly seen to have local rotting. After ripening at a too low temperature environment of 4℃, the banana, mango and avocado skins still have a large area of green color, that is, the maturity of the three at 4℃ environment is not high, and the banana and mango skins appear local blackening, showing obvious cold damage. After ripening at 12℃ environment, the green color area of the banana, mango and avocado skins is mostly faded, with good maturity, and the skins of the three kinds of fruits are clean and have no obvious black spots and anthracnose, and the avocado slices show good flesh quality and no rotting. Therefore, according to the experimental results, using 12℃ low temperature to ripen and store fruits can not only make the fruits have good maturity, but also be beneficial to fruit preservation, can ensure the quality of the fruits, and prevent the fruits from being damaged by cold due to too low temperature, or rotting or producing anthracnose due to high temperature.

[0060] The refrigeration equipment 10 of the utility model, including first storage box assembly 200 and second storage box assembly 300, first storage box assembly 200 includes first storage space 211 and the ripening device 220 of being arranged at first storage space 211, the fruit and vegetable of lower maturity can be put into first storage space 211 and store, through ripening device 220 can promote the maturity of fruit and vegetable;Second storage box assembly 300 includes second storage space 311 and the ripening device 320 of being arranged at second storage space 311, the fruit and vegetable of higher maturity or the fruit and vegetable after ripening device 220 ripening can be put into second storage space 311 and store, through ripening device 320 to slow down the maturity rate of fruit and vegetable, prevent fruit and vegetable over-ripe, so that the refrigeration equipment has ripening function and ripening function, can improve the maturity of fruit and vegetable, and can prevent fruit and vegetable over-ripe, can satisfy the demand of user. Moreover, the ripening device 220 of the utility model adopts physical method and ripens at the first temperature, compared with the ripening method of ethylene and high temperature in the related art, there is no restriction of high temperature demand, by setting the first temperature between 12 ℃-15 ℃, the fruit and vegetable in first storage space 211 can be in a lower temperature environment, which can slow down the nutrient consumption and water loss of fruit and vegetable, which is beneficial to maintaining the freshness of fruit and vegetable during the ripening process, and reduces the risk of infection and corruption of pathogenic bacteria, and the temperature is not too low, which can avoid physiological freezing injury of fruit and vegetable, so that the refrigeration equipment of the utility model adopts low temperature combined with physical ripening, which can not only improve the maturity of fruit and vegetable, but also ensure the quality of fruit and vegetable.

[0061] Light is an important environmental factor affecting the growth and development of plants. A certain amount of light can induce chlorophyll decomposition, increase the synthesis of related pigments, induce the appearance of an ethylene peak, and promote fruit and vegetable ripening. In some embodiments, the ripening device 220 includes a light source 221 for emitting light of a predetermined wavelength to the first storage space 211 to promote the ripening of fruits and vegetables in the first storage space 211 under light. The light source 221 can be a light panel, a light bar, or the like.

[0062] Please continue to refer to Figures 4 to 6 The applicant of the utility model also sets up a control group to ripen bananas, mangoes, and avocados in a 12℃ light environment. As can be seen from the figure, the skins of the above-mentioned fruits are darker after ripening under light, that is, the maturity of the above-mentioned fruits under light is higher than that without light. In particular, the skin of the mango is almost entirely yellow after ripening under light for 9 days, while there is still a small part of the green area on the skin of the mango after ripening for 9 days in the dark. Obviously, light can accelerate the ripening speed of fruits and make fruits ripen more easily. In this way, the present embodiment ripens by combining low temperature with light, which not only effectively improves the maturity of fruits and vegetables, but also guarantees the quality of fruits and vegetables.

[0063] Red light is important for the development of plant photosynthetic apparatus, and red light can increase the net photosynthetic rate to promote the growth and development of plants. Blue light can promote the development of chloroplasts, stomatal opening, and branch growth. To verify the ripening effect of red light and blue light on fruits and vegetables, the applicant of the utility model sets up three groups of fruits (mainly small mangoes and avocados) of the same maturity under the same temperature for experiments. One group of fruits matures naturally without light, and the other two groups of fruits are irradiated with blue light and red light, respectively. For convenience of explanation, the naturally ripened fruits are defined as the first group, the fruits irradiated with blue light are defined as the second group, and the fruits irradiated with red light are defined as the third group. After two days of ripening, the maturity of the fruits is comprehensively judged by the hardness and sweetness indicators, and it is detected that the maturity of the first group is less than that of the second group, and the maturity of the second group is less than that of the third group. Therefore, according to the experimental results, it is further confirmed that the ripening effect of light irradiation on fruits and vegetables is better than that of natural ripening of fruits and vegetables without light, and it is known that the ripening effect of red light on fruits and vegetables is better than that of blue light on fruits and vegetables.

[0064] To improve the ripening efficiency of fruits and vegetables, in one embodiment, the light of the predetermined wavelength is red light, and the light source 221 is configured to emit red light to ripen the fruits and vegetables in the first storage space 211.

[0065] The first storage box assembly 200 is provided with a support surface (not shown) for carrying fruits and vegetables. In order to make the light emitted by the light source 221 shine on all the fruits and vegetables as evenly as possible, the light source 221 can be set at the top of the first storage space 211. The light source 221 is opposite to the support surface and is spaced apart, so that the light source 221 emits light from the top and downwards, and the light can fully shine on the fruits and vegetables carried on the support surface, so that the surface of the fruits and vegetables is evenly illuminated, and the fruits and vegetables are prevented from ripening unevenly.

[0066] To understand the effects of different light intensities on the ripening of fruits and vegetables, the applicant of this utility model set up three experimental groups and one control group. The three experimental groups were subjected to low-intensity, medium-intensity, and high-intensity red light to ripen avocados by light, respectively. The control group was allowed to ripen naturally without light. The table below shows the light intensity values ​​for each group. It should be noted that the average light intensity in the table is the average light intensity at various locations on the support surface, and the central light intensity is the light intensity at the central location on the support surface.

[0067] Light intensity Average light intensity on the support surface (pmol / m2 / s) Central light intensity on the support surface (pmol / m2 / s) Low 10 15 Medium 25 40 High 45 75

[0068] Please refer to Figure 7 , Figure 7 These are graphs showing the changes in firmness and sugar content of various groups of fruits under different light intensities during ripening, according to embodiments of this utility model. Figure 7 The hardness variation graph in (A) shows that, under the same temperature and ripening time, the harder the avocado, the greater the change in light intensity (red light), and the lower the hardness of the ripened avocado, the higher the light intensity. Figure 7 The sugar content change graph in (B) shows that, under the same temperature and ripening time, the sugar content of avocados changes more significantly with increasing red light intensity, and the higher the light intensity, the higher the sugar content. Since changes in firmness and sugar content are the main indicators of fruit and vegetable ripeness, the higher the light intensity of light source 221, the higher the ripeness of the fruits and vegetables after ripening. This indicates that a high-intensity light environment has a superior ripening effect on fruits and vegetables.

[0069] Therefore, in order to improve the ripening efficiency of fruits and vegetables, high-intensity light can be used to ripen them. In one embodiment, the light source 221 is configured to make the average light intensity irradiated onto the support surface greater than or equal to 45 μmol / m² / s, and the center light intensity irradiated onto the support surface greater than or equal to 75 μmol / m² / s.

[0070] In one embodiment, reference Figure 1 As shown, the first storage box assembly 200 also includes a first heating element 230, which is used to generate heat to raise the temperature inside the first storage space 211 to a first temperature. The first heating element 230 can be a heating wire, graphene, or the like.

[0071] Specifically, in the initial state, the first heating member 230 is in the off state, and the temperature in the first storage space 211 is the second temperature, which is equal to the refrigeration temperature of the refrigeration compartment 110. The temperature of the refrigeration compartment is generally between 2°C and 8°C. When the fruits need to be ripened, the first heating member 230 is started, and the first heating member 230 generates heat to increase the temperature in the first storage space 211 to the first temperature. When the fruits are mature and taken out, the first heating member 230 is turned off, and the heating stops, so that the temperature in the first storage space 211 gradually decreases to the second temperature.

[0072] Please refer to Figure 8 The first storage box assembly 200 can further include a first trigger member 240 connected with the first heating member 230, and the first trigger member 240 is configured to trigger the first heating member 230 to start or turn off. The first trigger member 240 can be a mechanical trigger mechanism such as a key or a button. For example, a key plate electrically connected with the first heating member 230 can be arranged in the first storage space 211. When the user puts the tropical fruits into the first storage space 211 for ripening, the first heating member 230 can be triggered to start by pressing the key plate. When the user wants to take out the tropical fruits and stop the ripening, the first heating member 230 can be triggered to turn off by pressing the key plate again. Of course, the first trigger member 240 can also be a sensor or other sensing device, and the embodiments of the present application do not make any limitation in this regard.

[0073] In some embodiments, please refer to Figure 2 The ripening inhibitor 320 includes an ethylene absorption member 321 configured to absorb ethylene released by the fruits and vegetables in the second storage space 311. The ethylene absorption member 321 can be an ethylene absorption box, and a gas exchange film can be arranged in the ethylene absorption box.

[0074] It can be understood that ethylene is released during the respiration of fruits. If not treated, the ethylene will be absorbed by the nearby fruits and vegetables to further ripen. In the present embodiment, the ethylene absorption member 321 is arranged in the second storage space 311 to absorb the ethylene released by the fruits and vegetables, so as to slow down the ripening speed of the fruits and vegetables and play a role in inhibiting ripening, thereby preventing the fruits and vegetables in the second storage space 311 from being over-ripened and deteriorated.

[0075] In some embodiments, please refer to Figure 2 The second storage box assembly 300 further includes a gas detector 330 configured to detect the concentration of ethylene in the second storage space 311. The ethylene absorption member 321 is configured to start when the gas detector 330 detects that the concentration of ethylene is greater than or equal to a preset concentration value, and to turn off when the gas detector 330 detects that the concentration of ethylene is less than the preset concentration value. The gas detector 330 can be an ethylene gas sensor.

[0076] Specifically, when the gas detector 330 detects that the ethylene concentration in the second storage space 311 is greater than or equal to the preset concentration value, the ethylene absorption member 321 is started to absorb the ethylene in the second storage space 311; when the gas detector 330 detects that the ethylene concentration in the second storage space 311 is less than the preset concentration value, the ethylene absorption member 321 is in a closed state. By setting the gas detector 330 to detect the ethylene concentration in the second storage space 311, the ethylene absorption member 321 is started only when the ethylene concentration in the second storage space 311 reaches a certain concentration, rather than being always in an open state, which can prolong the service life of the ethylene absorption member 321.

[0077] In some embodiments, please continue to refer to Figure 2 The second storage box assembly 300 further comprises a fan 360, which is arranged in the second storage space 311. During operation of the fan 360, the gas in the second storage space 311 can be stirred to flow, so that the ethylene released by the fruits and vegetables can move with the airflow, preventing the ethylene from stagnating near the fruits and vegetables to cause further ripening of the fruits and vegetables. Moreover, by blowing the gas to flow through the fan 360, the ethylene can be uniformly distributed in the second storage space 311, which is not only beneficial to the gas detector 330 to accurately detect the real-time concentration of ethylene, improve the reliability of detection to ensure that the ethylene absorption member 321 can be started in time, but also beneficial to the ethylene absorption member 321 to better and more fully absorb ethylene.

[0078] The fan 360 can be configured to be continuously in operation or to be started at a fixed time, which is not limited in the embodiments of the present application.

[0079] Since the suitable storage temperature of tropical fruits is between 12℃-15℃, and the suitable storage temperature of non-tropical fruits is relatively lower, in order to better inhibit the ripening and preserve the freshness of different fruits, the second storage space 311 can be configured as a variable-temperature space.

[0080] In an embodiment, the second storage space 311 is a variable-temperature space, and the temperature of the second storage space 311 can be switched between a third temperature and a first temperature. The third temperature is equal to the temperature of the refrigeration chamber, which can be 2℃-8℃. The temperature of the second storage space 311 can be adjusted according to the actual stored fruits, so that the fruits in the second storage space 311 are in the best storage temperature environment, which is beneficial to the preservation of the fruits. For example, when storing conventional fruits, the temperature of the second storage space 311 is adjusted to the third temperature, and when storing tropical fruits, the temperature of the second storage space 311 is adjusted to the first temperature.

[0081] In an embodiment, please refer to Figure 2 and Figure 9The second storage box assembly 300 comprises a second heating element 340 and a second triggering element 350. The second heating element 340 is used for heating, and can be a heating wire, graphene, etc. The second triggering element 350 is connected to the second heating element 340, and is used for triggering the start or stop of the second heating element 340. When the second heating element 340 is started, the second heating element 340 generates heat to raise the temperature in the second storage space 311 to the first temperature; when the second heating element 340 is stopped, the second heating element 340 stops generating heat to lower the temperature in the second storage space 311 to the third temperature. As described above, the second triggering element 350 can be a mechanical triggering mechanism such as a button or a sensor, and will not be described here.

[0082] In some embodiments, the first storage box assembly 200 comprises a first storage drawer 210, which forms the first storage space 211 described above, and the second storage box assembly 300 comprises a second storage drawer 310, which forms the second storage space 311 described above. The refrigeration chamber 110 is provided with a drawer frame, and the first storage drawer 210 and the second storage drawer 310 are movably arranged in the drawer frame. In an embodiment, the first storage drawer 210 and the second storage drawer 310 are arranged along the width direction of the cabinet 100. In order to prevent the temperatures of the first storage space 211 and the second storage space 311 from affecting each other, a heat insulation baffle (not shown) is arranged between the first storage drawer 210 and the second storage drawer 310. The heat insulation baffle can be a foam board.

[0083] In an embodiment, referring to Figure 10 and Figure 11 , the first storage box assembly 200 comprises a first bottom plate 212 for carrying fruits and vegetables, and the first heating element 230 is arranged on the first bottom plate 212. The heat generated by the first heating element 230 can be directly transmitted to the fruits and vegetables, so that the fruits and vegetables can be quickly raised to the first temperature for light curing. Similarly, the second storage box assembly 300 comprises a second bottom plate 312 for carrying fruits and vegetables, and the second heating element 340 is arranged on the second bottom plate 312.

[0084] In order to prevent the first heating element 230 from causing the temperature of the refrigeration chamber 110 to rise, the first storage box assembly 200 can comprise a first heat insulation element 250 arranged between the first bottom plate 212 and the first heating element 230. The first heat insulation element 250 has a heat insulation effect, preventing the heat generated by the first heating element 230 from being directly transmitted to the first bottom plate 212, and reducing the impact of the heat generated by the first heating element 230 on the temperature in the refrigeration chamber 110.

[0085] Similarly, the second storage box assembly 300 can also include a second heat insulation piece 370 arranged between the second bottom plate 312 and the second heating piece 340, which blocks the heat generated by the second heating piece 340 from being directly transmitted to the second bottom plate 312 and reduces the impact of the heat generated by the second heating piece 340 on the temperature of the refrigeration compartment 110.

[0086] In some embodiments, the drawer frame is provided with a first open end for the first storage drawer 210, and the first open end is provided with a first sealing piece (not shown), which is used to block the gap between the first storage drawer 210 and the drawer frame when the first storage drawer 210 is not pulled out, so that the first storage space 211 is in a sealed state to prevent the hot air generated by the first heating piece 230 from entering the refrigeration compartment 110 and affecting the temperature of the refrigeration compartment 110.

[0087] Similarly, the drawer frame is provided with a second open end for the second storage drawer 310 to be pulled out, and the second open end is provided with a second sealing piece (not shown), which is used to block the gap between the second storage drawer 310 and the drawer frame when the second storage drawer 310 is not pulled out, so that the second storage space 311 is in a sealed state to prevent the hot air generated by the second heating piece 340 from entering the refrigeration compartment 110 and affecting the temperature of the refrigeration compartment 110.

[0088] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by the ordinary skilled in the art without departing from the purpose of the utility model.
