Description
Technical Field
[0001] This application relates to the field of heating and heat preservation, and particularly relates to a heating and heat preservation box and a vehicle. Background Art
[0002] With the development of the times, takeout ordering service has become a part of daily life. However, during the takeout delivery process, due to the delivery distance or delivery time, when the takeout is delivered to the customer, it often gets cold, resulting in a poor taste when consumed.
[0003] Especially in a cold environment like winter, the probability that the takeout delivered to the user gets cold is extremely high, leading to a very poor user experience, so it needs to be addressed. Summary of the Utility Model
[0004] The purpose of this application is to provide a heating and heat preservation box and a vehicle.
[0005] According to the first aspect of the embodiments of this application, a heating and heat preservation box is provided for heating and heat preserving the object to be contained. The heating and heat preservation box includes:
[0006] An outer layer part that encloses an accommodation space for accommodating the object to be contained and has an open end;
[0007] An inner layer part that is arranged in the accommodation space, is used for heating the accommodation space, and the thermal conductivity of the outer layer part is less than that of the inner layer part;
[0008] A sealing part that is arranged at the open end and is used for switching the open end between a first state and a second state;
[0009] When the open end is in the first state, the open end is closed, and when the open end is in the second state, the open end is open.
[0010] It should be noted that for the inner layer part of this embodiment, materials with good thermal conductivity such as copper and aluminum metals can be selected; for the outer layer part, materials such as asbestos, glass wool, and polystyrene foam can be selected, and these materials have poor thermal conductivity. The inner layer part can be a heated sheet or a bag for accommodating items, and this application does not make any restrictions. The sealing part can be a flip cover for covering the open end to close the open end, or it can be a connecting piece for closing the open end together. In addition, the object to be contained here can not only be takeout but also other items that need heat preservation, such as fish that need to be transported at an appropriate temperature.
[0011] When using the heating and insulation box of the present application, first, operate the sealing part to make the opening end in the second state, that is, the open state, and then place the object to be contained in the accommodating space. After the object to be contained is placed in the accommodating space, the user operates the sealing part again to make the opening end in the first state, so as to close the heating and insulation box, thereby preventing the heat in the heating and insulation box from overflowing. Thereafter, the inner layer part can provide heat to the object to be contained to ensure the temperature of the object to be contained during transportation. Therefore, after a long-time distribution, when the user gets the object to be contained, the object to be contained can still maintain its temperature, thus improving the user experience.
[0012] In some embodiments, the inner layer part includes a heating unit and a stretching unit. The stretching unit is connected to the heating unit to form a placement space. The stretching unit can be stretched and contracted to change the placement space. The placement space is located in the accommodating space and is used to accommodate the object to be contained and heat the object to be contained.
[0013] Based on the above settings, the object to be contained can be placed in the placement space for heating. However, due to the different shapes of the objects to be contained, it is easy to squeeze the wall surface of the placement space during placement, thereby damaging the inner layer part. In this embodiment, the stretching unit is used as the wall surface of the placement space, so that the size of the placement space can be changed. With such a setting, on the one hand, it is convenient for the object to be contained to be placed without damaging the inner layer part, and on the other hand, the space of the placement space can also be increased.
[0014] In some embodiments, the heating unit includes at least two side units. The two side units are arranged opposite to each other, and the stretching unit is arranged between the two side units and connects the two side units;
[0015] The two side units can move away from each other to increase the length of the stretching unit.
[0016] The user can stretch the stretching unit by separating the two side units, thereby increasing the space of the placement space. In addition, since two side units are provided, the two sides of the placement space can be heated, so that the object to be contained can be heated more evenly.
[0017] In some embodiments, the inner layer part further includes a bottom unit. Two sides of the bottom unit are respectively connected to the two side units, and the two side units are electrically connected to the bottom unit and share a power supply device.
[0018] In this embodiment, the bottom unit is provided. On the one hand, the bottom unit can further provide bottom heating for the object to be contained, further making the heating of the object to be contained more uniform. On the other hand, the bottom unit can be connected to the two side units, so that only one power supply device is needed to achieve all heating.
[0019] In some embodiments, the surface of the heating unit that encloses the placement space is made of a waterproof material.
[0020] Based on the above settings, even if the food in the placement space is overturned, especially food such as milk tea and soup, there will be no problem of damaging the heating unit.
[0021] In some embodiments, the outer layer includes two relatively arranged first heat-insulating surfaces and two relatively arranged second heat-insulating surfaces, and the first heat-insulating surface and the second heat-insulating surface are connected to each other to form an accommodation space, and the second heat-insulating surface includes two surface units connected to each other. When the two first heat-insulating surfaces approach each other, the two surface units approach each other with the connection point as the center;
[0022] The sealing part includes a first seal and a second seal. The first seal includes two first sealing units that are detachably connected. The two first sealing units are respectively arranged on the two first heat-insulating surfaces. The second seal includes two second sealing units that are detachably connected. The two second sealing units are respectively arranged on the two surface units;
[0023] When the open end is in the first state, the two first sealing units are connected to each other, and the two second sealing units are connected to each other.
[0024] It should be noted that the first seal and the second seal here can be zippers, Velcro, buttons, etc. The first sealing unit and the second sealing unit are a part of the first seal and the second seal, that is, half of a zipper, Velcro, button, etc.
[0025] The two first sealing units are connected to each other so that the open ends of the two first heat-insulating surfaces are connected to each other. The two second sealing units are connected to each other so that the open ends of the two surface units are folded to be connected to each other. Among them, the connection of the open ends of the two first heat-insulating surfaces and the folding of the open ends of the two surface units to be connected to each other can completely close the open end, thereby preventing the heat in the accommodation space from overflowing.
[0026] In some embodiments, the inner layer includes a heating unit and a stretching unit. The heating unit includes at least two side units. The two side units are relatively arranged, and the stretching unit is arranged between the two side units and connects the two side units;
[0027] The side unit is arranged corresponding to the first heat-insulating surface, and the stretching unit is arranged corresponding to the second heat-insulating surface.
[0028] Based on the above settings, since the second heat-insulating surface has two surface units, and when the two surface units are in the first state, there will be at least partial overlap, resulting in at least partial overlap of the corresponding parts of the inner layer of the accommodation space. If the surface corresponding to the second heat-insulating surface is a heating unit, it will be damaged or even leaked due to multiple folds. In this embodiment, the stretching unit is correspondingly arranged with the second heat-insulating surface. Since the stretching unit has flexibility, it can well adapt to being folded multiple times, thus avoiding damage caused by multiple folds.
[0029] In some embodiments, the inner layer includes a proximal end close to the open end, and the distance between the proximal end and the open end is greater than or equal to 1 cm.
[0030] Since there is a certain distance between the proximal end and the open end, the open end will not directly contact the proximal end. Such a setting can, on the one hand, prevent the heat generated by the inner layer from being directly discharged, and on the other hand, prevent the sealing part from being heated by the inner layer, thus preventing the hand from being scalded when operating the sealing part.
[0031] In some embodiments, the heating and heat-insulating box includes a controller unit. The inner layer is connected to the controller unit, and the controller unit is used to control the opening, closing, and opening intensity of the inner layer; and a side pocket is provided on the side of the outer layer facing away from the inner layer, and the controller unit is arranged in the side pocket; and / or,
[0032] The heating and heat-insulating box includes a mobile power source, and the mobile power source is connected to the inner layer; and a side pocket is provided on the side of the outer layer facing away from the inner layer, and the mobile power source is arranged in the side pocket.
[0033] The controller unit can be an IOT controller, which has Bluetooth near-field communication / 4G / 5G networking capabilities. It can collect the temperature of the heating and heat-insulating bag through a temperature sensor and synchronize it to the cloud. After being equipped with the IOT controller, the temperature of the heat-insulating bag can be viewed in real time through a mobile phone APP via Bluetooth and more accurate control can be performed, or the temperature of the heat-insulating bag can be viewed remotely through the network or more accurate control can be performed.
[0034] The mobile power source can be a common mobile power source or a small storage battery on the market, which can provide a common power supply capacity of 5V to 12V and about 2A. And the mobile power source can move with the heating and heat-insulating box, thus ensuring the continuous power supply capacity of the heating and heat-insulating box.
[0035] According to the second aspect of the embodiments of the present application, a vehicle is provided, and the vehicle includes the heating and heat-insulating box as described in the above embodiments. Description of the Drawings

[0061] With the development of the times, the takeout food ordering service has become a part of daily life. However, during the delivery of takeout food, due to the delivery distance or delivery time, when the takeout food reaches the customer, it often gets cold, resulting in a poor taste. Especially in a cold environment like winter, the probability that the takeout food delivered to the user gets cold is extremely high, leading to a very poor user experience, so it needs to be addressed.
[0062] Referring to Figure 1 and Figure 2 As shown, the present application provides a heating and heat preservation box 10 for heating and heat preserving the object to be contained. The heating and heat preservation box 10 includes an outer layer 100, an inner layer 200, and a sealing part 300. The outer layer 100 encloses an accommodation space 110 for accommodating the object to be contained, and has an open end 120. The inner layer 200 is disposed in the accommodation space 110 and is used for heating the accommodation space 110. The thermal conductivity of the outer layer 100 is less than that of the inner layer 200, and is used for heat preservation of the heat emitted by the inner layer 200. The sealing part 300 is disposed at the open end 120 and is used for switching the open end 120 between a first state and a second state. When the open end 120 is in the first state, the open end 120 is closed, and when the open end 120 is in the second state, the open end 120 is open.
[0063] It should be noted that for the inner layer part 200 of this embodiment, materials with good thermal conductivity such as copper and aluminum metals can be selected; for the outer layer part 100, materials such as asbestos, glass wool, and polystyrene foam can be selected, and these materials have poor thermal conductivity. The inner layer part 200 can be a heated sheet or a bag for accommodating items, and the present application does not limit this. The sealing part 300 can be a flip cover for covering the open end 120 to close the open end 120. It can also be a connecting piece for closing the open end 120 together to close the open end 120. In addition, the item to be accommodated here can not only be takeout but also other items that need to be kept warm, such as fish that need to be transported at an appropriate temperature. The "heating insulation box" shown above can be a box structure fixed on a takeout vehicle or a portable luggage, takeout bag, etc. structure.
[0064] When using the heating insulation box 10 of the present application, first, operate the sealing part 300 to make the open end 120 in the second state, that is, the open state, and then place the item to be accommodated in the accommodation space 110. After the item to be accommodated is placed in the accommodation space 110, the user operates the sealing part 300 again to make the open end 120 in the first state, closing the heating insulation box 10 to prevent the heat inside the heating insulation box 10 from escaping. After that, the inner layer part 200 can provide heat to the item to be accommodated to ensure the temperature of the item to be accommodated during transportation. Therefore, after a long delivery time, when the user gets the item to be accommodated, the item to be accommodated can still maintain its temperature, thus improving the user experience.
[0065] In this embodiment, continue to refer to Figure 1 Combined Figure 2 As shown, the inner layer part 200 includes a heating unit 210 and a stretching unit 220. The stretching unit 220 is connected to the heating unit 210 to form a placement space 230. The stretching unit 220 can be stretched and contracted to change the placement space 230. The placement space 230 is located in the accommodation space 110 and is used to accommodate the item to be accommodated and heat the item to be accommodated.
[0066] Based on the above settings, the item to be accommodated can be placed in the placement space 230 for heating. However, since the shapes of the items to be accommodated are different, it is easy to squeeze the wall surface of the placement space 230 during placement, thereby damaging the inner layer part 200. In this embodiment, the stretching unit 220 is used as the wall surface of the placement space 230, so that the size of the placement space 230 can be changed. With this setting, on the one hand, it is convenient to place the item to be accommodated without damaging the inner layer part 200, and on the other hand, the space of the placement space 230 can also be increased.
[0067] In this embodiment, continue to refer to Figure 1 And Figure 2As shown, the heating unit 210 includes at least two side units 211 which are oppositely arranged, and the stretching unit 220 is arranged between the two side units 211 and connects the two side units 211; the two side units 211 can move away from each other to increase the length of the stretching unit 220.
[0068] Refer to Figure 2 As shown, the user can stretch the stretching unit 220 by separating the two side units 211, thereby increasing the space of the placement space 230. In addition, since two side units 211 are provided, heating can be performed on both sides of the placement space 230, so that the object to be contained can be heated more evenly.
[0069] In this embodiment, refer to Figure 1 and Figure 2 As shown, the inner layer part 200 further includes a bottom unit 212. Both sides of the bottom unit 212 are respectively connected to the two side units 211, and the two side units 211 are electrically connected to the bottom unit 212 and share a power supply device.
[0070] In this embodiment, the bottom unit 212 is provided. On the one hand, the bottom unit 212 can further provide bottom heating for the object to be contained, further making the heating of the object to be contained more uniform. On the other hand, the bottom unit 212 can be connected to the two side units 211, so that only one power supply device is needed to achieve all heating. Of course, the temperatures of the bottom unit 212 and the side units 211 can be different to avoid overheating of the bottom of the placement space 230 and affecting the quality of the object directly in contact with the bottom.
[0071] In this embodiment, the surface of the heating unit 210 that encloses the placement space 230 is made of waterproof material. Based on the above setting, even if the food in the placement space 230 is overturned, especially for food such as milk tea and soup that is overturned, there will be no problem of damaging the heating unit 210.
[0072] In this embodiment, refer to Figure 1 and Figure 2As shown, the outer layer part 100 includes two oppositely arranged first heat-insulating surfaces 130 and two oppositely arranged second heat-insulating surfaces 140. The first heat-insulating surfaces 130 and the second heat-insulating surfaces 140 are connected to each other to form a receiving space 110. The second heat-insulating surface 140 includes two surface units 141 connected to each other. When the two first heat-insulating surfaces 130 approach each other, the two surface units 141 approach each other with the connection part as the center; the sealing part 300 includes a first seal 310 and a second seal 320. The first seal 310 includes two first sealing units 311 that are detachably connected. The two first sealing units 311 are respectively arranged on the two first heat-insulating surfaces 130. The second seal 320 includes two second sealing units 321 that are detachably connected. The two second sealing units 321 are respectively arranged on the two surface units 141; when the open end 120 is in the first state, the two first sealing units 311 are connected to each other, and the two second sealing units 321 are connected to each other.
[0073] It should be noted that the first seal 310 and the second seal 320 here can be zippers, Velcro, buttons, etc. The first sealing unit 311 and the second sealing unit 321 are a part of the first seal 310 and the second seal 320 respectively. Refer to Figure 1 and Figure 2 shown, that is, half of a zipper, Velcro, buttons, etc.
[0074] Refer to Figure 2 shown, the two first sealing units 311 are connected to each other so that the open ends 120 of the two first heat-insulating surfaces 130 are connected to each other, and the two second sealing units 321 are connected to each other so that the open ends 120 of the two surface units 141 are folded to be connected to each other. Among them, the connection of the open ends 120 of the two first heat-insulating surfaces 130 and the folding of the open ends 120 of the two surface units 141 to be connected to each other can completely close the open end 120, thereby preventing the heat in the receiving space 110 from overflowing.
[0075] In this embodiment, refer to Figure 1 and Figure 2 shown, the two side units 211 are oppositely arranged, and the stretching unit 220 is arranged between the two side units 211 and connects the two side units 211; the side unit 211 is arranged corresponding to the first heat-insulating surface 130, and the stretching unit 220 is arranged corresponding to the second heat-insulating surface 140.
[0076] Based on the above settings, since the second heat-insulating surface 140 has two surface units 141, and when the two surface units 141 are in the first state, there will be at least partial overlap, resulting in at least partial overlap of the corresponding part of the inner layer 200 located in the accommodation space 110. If the surface corresponding to the second heat-insulating surface 140 is the heating unit 210, it will be damaged or even leak electricity due to multiple folds. In this embodiment, the stretching unit 220 is arranged corresponding to the second heat-insulating surface 140. Since the stretching unit 220 has flexibility, it can well adapt to being folded multiple times, thus avoiding damage caused by multiple folds.
[0077] In one embodiment, referring to Figure 2 as shown, the inner layer 200 includes a proximal end 240 close to the opening end 120, and the distance between the proximal end 240 and the opening end 120 is greater than or equal to 1 cm. For example, the distance between the proximal end 240 and the opening end 120 can be 1 cm, 2 cm, 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, 10 cm.
[0078] Since there is a certain distance between the proximal end 240 and the opening end 120, the opening end 120 does not directly contact the proximal end 240. With this setting, on the one hand, it can prevent the heat generated by the inner layer 200 from being directly discharged, and on the other hand, it can also prevent the sealing part 300 from being heated by the inner layer 200, thus preventing the hand from being scalded when operating the sealing part 300.
[0079] In this embodiment, the heating incubator 10 can also be provided with a temperature sensor 400 (not shown in the figure), and the temperature sensor 400 is arranged between the proximal end 240 and the opening end 120 for detecting the temperature of the accommodation space 110.
[0080] In one embodiment, referring to Figure 1 and Figure 2 as shown, the heating incubator 10 includes a controller unit (not shown in the figure). The inner layer 200 is connected to the controller unit, and the controller unit is used to control the opening, closing and opening intensity of the inner layer 200; and a side pocket (not shown in the figure) is provided on the side of the outer layer 100 facing away from the inner layer 200, and the controller unit is arranged in the side pocket.
[0081] The controller unit can be an IOT controller, which has Bluetooth near-field communication / 4G / 5G networking capabilities. It can collect the temperature of the heating insulation bag through the temperature sensor 400 and synchronize it to the cloud. After being equipped with the IOT controller, the temperature of the insulation bag can be viewed in real time through the mobile phone APP via Bluetooth and more accurate control can be carried out, or the temperature of the insulation bag can be viewed remotely through the network or more accurate control can be carried out.
[0082] In one embodiment, referring toFigure 1 and Figure 2 As shown in Figure 2 , the heating incubator 10 includes a mobile power source (not shown in the figure), and the mobile power source is connected to the inner layer part 200; and a side pocket is provided on the side of the outer layer part 100 facing away from the inner layer part 200, and the mobile power source is arranged in the side pocket.
[0083] The mobile power source can be a common mobile power source or a small storage battery on the market, and can provide a common power supply capacity of 5V to 12V and about 2A. And the mobile power source can move along with the heating incubator 10, thus ensuring the continuous power supply capacity of the heating incubator 10.
