Description

Technical Field

[0001] This invention relates to the field of food storage equipment technology, and in particular to a food storage component and its heating control method. Background Technology

[0002] In today's society, people are paying increasing attention to food safety and demanding healthier diets. More and more office workers are choosing to cook their own meals and bring them to work. This has led to increased focus on food storage methods and convenient reheating options. As the number of people bringing their own lunches grows, companies are increasingly requiring standardized storage and management of lunchboxes. Currently, various types of combined hot and cold food lunchboxes are available on the market.

[0003] A portable lunchbox with integrated heating and cooling functions is disclosed in the prior art. This portable lunchbox includes a heating base and a container box, which are detachably connected. The heating base includes a heating and cooling device for heating and cooling the lunchbox. This portable lunchbox has both heating and cooling functions, and for daily use, only the container box needs to be carried, making it convenient and quick. However, to achieve both heating and cooling, this type of lunchbox usually needs to be equipped with its own heating and cooling device, which undoubtedly increases the size and weight of the lunchbox, reduces its space utilization, and is not convenient for centralized storage and management.

[0004] Another prior art discloses a solar-powered sterilizing lunchbox storage cabinet. This cabinet includes a cabinet body, a base, a first flap, a second flap, a third flap, ultraviolet lamps, a converter, and a battery. The cabinet body is mounted on the base, and the converter and battery are both housed inside the base. The first flap is hinged to the top of the cabinet body, and the second and third flaps are hinged to the side walls of the cabinet body. Solar photovoltaic panels are arranged on the first, second, and third flaps, as well as on the back panel of the cabinet body, converting solar energy into electrical energy, which is stored in the battery. Each lunchbox storage space inside the cabinet is equipped with an ultraviolet lamp, powered by the battery. This storage cabinet can meet the need for centralized management of lunchboxes, but it does not provide cooling or heating functions beyond solar-powered sterilization.

[0005] Therefore, in order to meet the requirements of heating and cooling lunch boxes, and to facilitate the centralized placement and management of lunch boxes, there is an urgent need to improve the existing lunch boxes and storage cabinets. Summary of the Invention

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0040] The following is in conjunction with the instruction manual appendix. Figures 1-6 Examples 1 and 2 provide a detailed description of the food storage component and its heating control method of the present invention.

[0041] Example 1

[0042] This embodiment provides a detailed description of the food storage component of the present invention.

[0043] The food storage component of this embodiment includes a storage box 10 and a storage cabinet 20, such as... Figures 1-3 As shown. Preferably, the storage box 10 has a receiving cavity 101 for storing food. The storage cabinet 20 has a compartment 201, in which the storage box 10 is placed. The storage cabinet 20 is equipped with a heating component and a cooling component. The heating component heats the storage box 10, and the cooling component cools the storage box 10. Figures 1-3 As shown. In this embodiment, the food storage component includes a storage box 10, for example, a lunchbox, and a storage cabinet 20, which is a lunchbox storage cabinet. This food storage component can be used in places where people gather, such as companies and schools. It not only facilitates users in refrigerating and heating food, but also facilitates centralized management.

[0044] The food storage component of this embodiment includes a storage box 10 and a placement cabinet 20. The storage box 10 has a receiving cavity for storing food. The placement cabinet 20 has a compartment in which the storage box 10 is placed. The placement cabinet 20 is equipped with a heating component and a cooling component. The heating component is used to heat the storage box 10, and the cooling component is used to cool the storage box 10, thereby enabling the heating and cooling of the food in the storage box 10. As can be seen, compared with the integrated heating and cooling lunch boxes in the prior art, the food storage component of this embodiment places the heating and cooling components inside the storage cabinet 20, so that the storage box 10 does not need to carry the heating and cooling components. This reduces the size and weight of the storage box 10 and improves the space utilization rate of the storage box 10. That is, the food storage component of this embodiment solves the technical problems of the existing integrated heating and cooling lunch boxes, such as large size and weight, low space utilization rate, and inconvenience for centralized placement and management. At the same time, by placing the heating and cooling components inside the storage cabinet 20, the storage cabinet 20 has both heating and cooling functions, which also solves the technical problem of the existing storage cabinet 20 lacking heating and cooling functions. On the other hand, the food storage component of this embodiment, by placing the storage box 10 in the compartment inside the storage cabinet 20, also facilitates the centralized management of the storage box 10.

[0045] According to a preferred embodiment, the heating assembly includes a heating water tank 202 and a circulating water tank 203, wherein both the heating water tank 202 and the circulating water tank 203 are connected to the chamber 201, and the heating water tank 202 is also connected to the circulating water tank 203. The heating water tank 202 is used to heat and generate water vapor, and the circulating water tank 203 is used to collect condensate generated in the chamber 201. Figure 5 As shown. Specifically, the heating water tank 202 is equipped with a heater, which is used to heat the water in the tank to generate steam. Figure 5 The arrows in the diagram indicate the direction of water vapor and condensate flow. For example... Figure 5 As shown, in this preferred embodiment, the food storage component generates high-temperature steam through a heating water tank 202. The steam then enters the compartment 201, raising the temperature inside the compartment 201 and heating the storage box 10 placed in the storage cabinet 20. On the other hand, after the steam enters the compartment 201, due to the low temperature of the walls of the compartment 201, the steam condenses into water and adheres to the walls of the compartment 201. The condensate then flows into the circulating water tank 203. There is excessive condensate in the walls of the compartment 201. Furthermore, the condensate collected in the circulating water tank 203 can be reheated in the heating water tank 202, thereby achieving water recycling.

[0046] According to a preferred embodiment, a first heat insulation plate 102 is provided inside the storage box 10, which divides the storage box 10 into multiple receiving cavities 101. At least some of the receiving cavities 101 are also provided with steam channels 103, which communicate with the compartments 201 and are used for the circulation of steam. Figure 1 As shown. Preferably, the water vapor channel 103 is located in the middle of the receiving cavity 101. For example... Figure 1 As shown, the storage box 10 is provided with two first heat insulation plates 102, dividing the storage box 10 into four accommodating chambers 101. The four accommodating chambers 101 can be used to hold different types of food. For example, the four accommodating chambers 101 can be used to hold hot dishes, cold dishes, rice, and soup, respectively. In the preferred embodiment of this food storage component, the accommodating chambers 101 are also provided with steam channels 103, so that the steam entering the compartments 201 enters the steam channels 103, thereby heating the food from the middle of the storage box 10, which can improve the heating effect of the food in the storage box 10. The steam channels 103 are only provided in some of the accommodating chambers 101, so that cold dishes can be held in the accommodating chambers 101 without steam channels 103, thereby improving the applicability of the storage box 10. On the other hand, the storage box 10 is divided into multiple accommodating chambers 101 by the first heat insulation plates 102, which can avoid the temperature of each accommodating chamber 101 from affecting each other, thereby preventing the food from changing its taste.

[0047] According to a preferred embodiment, a water vapor channel 103 is vertically disposed within a receiving cavity 101. The surface of the water vapor channel 103 has an arc-shaped structure, and the outer diameter of the water vapor channel 103 gradually decreases from one end near the bottom surface of the receiving cavity 101 to the end away from the bottom surface of the receiving cavity 101. Figure 1 and Figure 3 As shown. In this preferred embodiment, the surface of the steam channel 103 is arc-shaped, which increases the contact area between the steam channel 103 and the food in the receiving cavity 101, thereby improving the heating efficiency of the food in the receiving cavity 101. Furthermore, since the food at the bottom of the receiving cavity 101 is more compacted than the food at the top, and requires a longer heating time, in this preferred embodiment, the outer diameter of the steam channel 103 gradually decreases from the end near the bottom surface of the receiving cavity 101 to the end away from the bottom surface of the receiving cavity 101. This makes the heating effect of the food at the bottom of the receiving cavity 101 better than that of the food at the top of the receiving cavity 101, thereby ensuring the uniformity of heating of the food throughout the receiving cavity 101.

[0048] According to a preferred embodiment, a steam chamber 104 is provided below the receiving cavity 101, the steam chamber 104 is connected to the steam channel 103, and an air inlet 105 is provided at the bottom of the steam chamber 104. A steam duct 204 is provided inside the compartment 201. When the storage box 10 is placed inside the compartment 201, the air inlet 105 is engaged with the steam duct 204. Figure 3 As shown. Preferably, a steam duct inlet 208 is provided at the back of the chamber 201. The steam generated in the heating water tank 202 enters the steam duct 204 through the steam duct inlet 208, such as... Figure 4 As shown. In this preferred embodiment, the food storage component has a steam chamber 104 located below the receiving cavity 101. The steam entering the chamber 201 from the heating water tank 202 first enters the steam duct 204 and then enters the steam chamber 104 through the air inlet 105. The steam in the steam chamber 104 can heat the bottom of the receiving cavity 101. At the same time, the steam in the steam chamber 104 can also enter each steam channel 103 to heat the food from the center of the receiving cavity 101.

[0049] According to a preferred embodiment, a second heat insulation plate is further provided inside the steam chamber 104. The second heat insulation plate is used to separate the receiving cavity 101 with the steam channel 103 from the receiving cavity 101 without the steam channel 103. Specifically, the air inlet 105 is located below the receiving cavity 101 with the steam channel 103. In the food storage component of this preferred embodiment, a second heat insulation plate is further provided inside the steam chamber 104. Through the action of the second heat insulation plate, steam can be prevented from entering the receiving cavity 101 without the steam channel 103, thereby avoiding heating of the food (such as cold dishes) in the receiving cavity 101 without the steam channel 103, and ensuring the quality of the food.

[0050] According to a preferred embodiment, the storage box 10 further includes a cover 106, which covers the receiving cavity 101, and the cover 106 is provided with a through hole 107, which communicates with the water vapor channel 103, allowing water vapor in the water vapor channel 103 to flow out through the through hole 107. Figure 1 As shown. In the preferred embodiment of the food storage component, when heating food, the through hole 107 is aligned with the steam channel 103, so that the steam in the steam channel 103 can flow out through the through hole 107 and enter the compartment 201. The steam entering the compartment 201 fills the compartment 201, and can also heat the outer wall of the storage box 10 through the steam in the compartment 201, thereby heating the food in the receiving cavity 101, which can further improve the heating efficiency of the food in the receiving cavity 101.

[0051] The preferred food storage component of this embodiment, by providing a steam channel 103 in the receiving cavity 101, a steam chamber 104 below the receiving cavity 101, and a through hole 107 on the cover 106, allows the food in the receiving cavity 101 to be heated by heat from below, center, and outer wall. This not only ensures the heating efficiency of the food in the receiving cavity 101, but also improves the uniformity of the food being heated.

[0052] According to a preferred embodiment, a control valve is provided at the steam duct 204. The control valve has an open state and a closed state. When the control valve is in the open state, the steam duct 204 is connected to the air inlet 105. When the control valve is in the closed state, the steam duct 204 is separated from the air inlet 105. The opening and closing of the control valve can be manually controlled or automatically controlled. In the food storage component of the preferred embodiment, the control valve at the steam duct 204 allows steam to enter the steam chamber 104 and the steam channel 103 by opening the control valve, thereby heating the food in the receiving cavity 101. When heating the food in the receiving cavity 101 is not required, closing the control valve prevents steam from entering the steam chamber 104 and the steam channel 103.

[0053] According to a preferred embodiment, a thermal insulation layer 205 is further provided inside the chamber 201, and a water vapor duct 204 is disposed within the thermal insulation layer 205, such as... Figure 3 As shown. Preferably, the insulation layer 205 can be made of insulation cotton. In the food storage component of the preferred embodiment, an insulation layer 205 is provided in the compartment 201. Through the insulation effect of the insulation layer 205, the heat loss of water vapor in the water vapor duct 204 and the water vapor chamber 104 can be avoided, thereby improving the heating effect on the food in the receiving cavity 101.

[0054] According to a preferred embodiment, the cross-sectional area of ​​the insulation layer 205 is smaller than the bottom area of ​​the compartment 201, and a gap is formed between the perimeter of the insulation layer 205 and the wall of the compartment 201, the gap being formed as a water tank 206. Figure 3 As shown. Preferably, the compartment 201 is also provided with a condensate outlet, which is connected to the circulating water tank 203. After water vapor enters the compartment 201, due to the low temperature of the wall surface of the compartment 201, the water vapor condenses into water upon contact with the condensate and adheres to the wall surface of the compartment 201, flowing down with the wall surface. In the food storage component of the preferred embodiment, a water tank 206 is formed between the perimeter of the insulation layer 205 and the wall surface of the compartment 201. The water tank 206 can be used to collect the flowing condensate and discharge it into the circulating water tank 203 through the condensate outlet.

[0055] According to a preferred embodiment, the top wall 207 of the compartment 201 has a sloping structure, and the height of the top wall 207 gradually decreases from the middle of the compartment 201 towards both sides of the compartment 201, such as... Figure 3 and Figure 4 As shown. In the preferred embodiment of the food storage component, the top wall 207 slopes downward from the middle of the compartment 201 toward both sides of the compartment 201, so that the condensate adhering to the top wall 207 can flow along the top wall 207 to both sides, and then flow into the water tank 206 for collection, and then be discharged into the circulating water tank 203 through the condensate outlet.

[0056] According to a preferred embodiment, the food storage assembly further includes a temperature sensing component disposed within the storage box 10, and the temperature sensing component is used to detect the temperature inside the storage box 10. The temperature sensing component is a temperature sensor. In this preferred embodiment, the food storage assembly further includes a temperature sensing component, which can monitor the temperature inside the storage box 10 to control the temperature within a suitable temperature range (e.g., 50–60°C), thereby ensuring the heating effect and food quality of the food inside the storage box 10.

[0057] According to a preferred embodiment, the refrigeration component is a direct-cooling refrigeration component. The direct-cooling refrigeration component can have the same structure as the direct-cooling refrigeration component in a refrigerator. Specifically, the direct-cooling refrigeration component includes a compressor, an evaporator, and a condenser. The compressor's outlet, condenser, evaporator, and compressor's return port form a refrigerant circuit and achieve refrigeration. The evaporator coil is located within compartment 201 or between two adjacent compartments 201. Heat exchange between the air in compartment 201 and the evaporator coil achieves refrigeration of compartment 201, thereby keeping the storage box 10 placed in compartment 201 in a refrigerated state to facilitate food preservation. However, the refrigeration component can also be any other refrigeration structure in the prior art. The evaporator may develop frost after prolonged use. In this preferred embodiment, the water vapor generated in the heating component can be used to defrost the evaporator during circulation, thereby saving energy.

[0058] Preferably, a deflector fan is also provided on the rear of the compartment 201, and the deflector fan is installed in the deflector fan mounting part 209, such as... Figure 4 As shown. When refrigerating food in the receiving cavity 101, the turbulence fan is turned on. Through the action of the turbulence fan, the air in the compartment 201 can be forced to circulate, thereby improving the temperature uniformity in the compartment 201 and thus improving the refrigeration effect of the food in the receiving cavity 101.

[0059] The food storage component of this preferred embodiment requires the storage box 10 and the storage cabinet 20 to be used together. However, it is not limited to this; when a storage box 10 that is not compatible with the storage cabinet 20 is placed inside the storage cabinet 20, it can only achieve the function of cooling the storage box 10, and cannot achieve the function of heating the storage box 10.

[0061] This embodiment provides a detailed description of the heating control method for the food storage component of the present invention.

[0062] Figure 6 A flowchart illustrating a preferred embodiment of the heating control method for the food storage component in this example is shown. Figure 6 As shown, the heating control method for a food storage component in any of the technical solutions in Embodiment 1 includes the following steps:

[0063] Step 1: Activate the heating mode by opening the control valve at the steam duct 204. Activation of the heating mode can be achieved manually via the app or by using the control switch on the storage box 10.

[0064] Step 2: Obtain the real-time temperature inside storage box 10 and compare the obtained real-time temperature with the preset temperature. The preset temperature is, for example, 50-60℃.

[0065] Step 3: Within the preset heating time, when the acquired real-time temperature exceeds the preset temperature, the control valve is closed; when the acquired real-time temperature is lower than the preset temperature, the control valve is opened. Preferably, the control valve is closed when the preset heating time is exceeded. The preset heating time is, for example, 10 minutes. For example, if the temperature is set to 52-55℃, the control valve is closed when the acquired real-time temperature is higher than 55℃; and opened when the acquired real-time temperature is lower than 52℃.

[0066] Preferably, the heating control method of the food storage component in this embodiment can also control the heating time.

[0067] The heating control method for the food storage component described in any of the technical solutions in this embodiment, by activating the heating mode, controlling the opening of the control valve at the steam duct 204, obtaining the real-time temperature inside the storage box 10, comparing the obtained real-time temperature with a preset temperature, and controlling the control valve to close when the obtained real-time temperature exceeds the preset temperature within a preset heating time, and controlling the control valve to open when the obtained real-time temperature is lower than the preset temperature, can achieve the heating of food in the storage box 10.
