Description

Technical Field

[0001] The present application relates to a heating device and a heating device kit. Background Art

[0002] In the prior art, there are portable heating devices in the form of, for example, a cartridge stove or a photovoltaic stove. Such portable heating devices can be used outdoors, for example, for heating food and the like. However, since a cartridge stove uses a liquefied gas cylinder for heating with an open flame, there may be certain safety risks. For example, in the case of improper operation or leakage of the liquefied gas cylinder, the cartridge stove may explode, causing serious personal injuries and property losses. In addition, heating with an open flame may also cause a fire due to improper use. A photovoltaic stove generally relies on a solar panel to convert light energy into electrical energy and then uses the obtained electrical energy for heating. Due to the limited photoelectric conversion efficiency, the actual heating power of the photovoltaic stove may be low, and the use of the photovoltaic stove is strongly affected by weather conditions, and it may be difficult to meet the use requirements on cloudy days, overcast days or at night.

[0050] The present application will be described below with reference to the accompanying drawings, in which several embodiments of the present application are shown. However, it should be understood that the present application can be presented in many different ways and is not limited to the embodiments described below; in fact, the embodiments described below are intended to make the disclosure of the present application more complete and to fully explain the scope of protection of the present application to those skilled in the art. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments.

[0051] It should be understood that the terminology in the specification is only used to describe specific embodiments and is not intended to limit the present application. All terms used in the specification (including technical terms and scientific terms) have the meaning commonly understood by those skilled in the art unless otherwise defined. For the sake of brevity and / or clarity, well-known functions or structures may not be described in detail.

[0052] The singular forms "a", "the", and "said" used in the specification include the plural forms unless clearly specified.

[0055] Figure 1 and Figure 2 A perspective view schematically showing a heating device 1 according to an embodiment of the present application. The heating device 1 can be used as a portable heating device. Specifically, the portable heating device in the present application can be understood as a heating device that can be used without being connected (e.g., via a pipeline) to an energy source such as a natural gas network or a domestic power grid. For example, the heating device 1 can be used as a kitchen utensil outdoors or in a restaurant, for example, for keeping food warm, heating, or cooking food. In addition, the heating device 1 can also have other diverse usage scenarios. For example, the heating device 1 can be used in a laboratory for water bath heating or disinfection of experimental utensils, etc.

[0056] The heating device 1 can include: a heating appliance 2, which can include a container 21 and a heating assembly 20 (see Figure 20 ), the heating assembly 20 being configured to at least partially heat the container 21. The container 21 can be configured in the form of, for example, a kettle, a frying pan, a soup pot, a crucible, etc. depending on the usage requirements. The heating assembly 20 can be particularly configured as an electric heating assembly, especially a direct current heating assembly, which can generate heat based on principles such as resistance heating, induction heating, arc heating, electron beam heating, infrared heating, or dielectric heating. Here, the heating assembly 20 can be configured as a heating wire, a heating tube, a heating plate, a carbon fiber heating film, an enamel heating film, a graphene heating film, etc. In some embodiments, the heating assembly 20 can be disposed in the lower part 22 of the heating appliance 2 (see Figure 3 and Figure 4) and is configured as a heating plate that abuts against the bottom region of the container 21 or forms the bottom region of the container 21 itself. The heating assembly 20 can be integrally constructed with the container 21. In some other embodiments, the heating assembly 20 and the container 21 can be configured to be detachable.

[0057] The heating device 1 includes a base 3, which may include a rechargeable battery 4 (see, for example, Figure 8 ), and the battery 4 is configured to supply power to the heating device 1, particularly the heating assembly 20. The rechargeable battery can particularly be configured as a lithium battery pack. Lithium batteries have the advantages of high energy density, low self-discharge rate, no memory effect, light weight, high charging efficiency, long service life, and environmental friendliness. Advantageously, the lithium battery pack can have a power of 400w to 1000w, particularly 480w to 800w. This is particularly suitable for the use purpose of the heating device 1 as a kitchen utensil. The heating appliance 2 can be detachably electrically coupled to the base 3 via a coupler to obtain electrical energy from the base 3, particularly the battery 4. As Figure 3 and Figure 4 shown, the coupler can include a first coupling member 23 provided on the heating appliance 2 and a second coupling member 31 provided on the base 3. Thus, the electrical coupling of the first coupling member 23 and the second coupling member 31, and thus the heating appliance 2 and the base 3, can be conveniently achieved by placing the heating appliance 2 on the base 3. The design that the heating appliance 2 and the base 3 can be separated from each other is beneficial for the cleaning and replacement of the heating appliance 2 when necessary. In some embodiments, the coupler can include two pairs of electrical contacts connected in parallel with each other. The electrical contacts can be configured as silver contacts. Thereby, the coupler can stably and reliably transmit large currents and high powers.

[0058] The heating device 1 according to the present application does not need to be pipeline-connected to a natural gas network or a household power grid, but advantageously uses a rechargeable battery 4, particularly a lithium battery pack, as an energy source, thus having good portability, environmental friendliness, use flexibility, and use safety. In addition, the heating device 1 according to the present application operates in an electrothermal manner and does not require the use of an open flame, and can be unaffected by weather conditions, and can stably and reliably achieve the heating function even in weather such as rain or wind. Therefore, the heating device 1 according to the present application is also particularly suitable for use in an outdoor environment.

[0059] In some embodiments, the base can be configured as multi-piece, particularly two-piece. As Figure 3 and Figure 4As can be seen most clearly, the base 3 may include a first base portion 5 and a second base portion 6. The first base portion 5 can be placed on or removed from the second base portion 6. Among them, the second coupling member 31 can be provided on the first base portion 5, and the second base portion 6 can include the rechargeable battery 4. By arranging the rechargeable battery 4 on the second base portion 6 that can be separated from the first base portion 5, it is possible to conveniently replace the second base portion 6 with another, for example, more fully charged battery 4 in the case where the battery 4 runs out of power, so as to continue using the heating device 1 according to the present application.

[0060] As Figure 5 and Figure 6 shown, the first base portion 5 may include a first upper housing 53 and a first lower housing 54. The first upper housing 53 and the first lower housing 54 can be connected to each other, for example, via threaded members and define the internal space of the first base portion 5 with respect to the surrounding environment. The second coupling member 31 can be provided on the first base portion 5, particularly connected to the first upper housing 53. The first upper housing 53 may include a recess 531, and the second coupling member 31 can be provided in the recess 531. The shape of the recess 531 can correspond to the lower portion 22 of the heating appliance 2 (see Figure 3 and Figure 4 ). Among them, the first coupling member 23 can be provided in the lower portion 22 of the heating appliance 2. Thus, the heating appliance 2 can be reliably installed on the first base portion 5 in such a way that its lower portion 22 is received in the recess 531 of the first upper housing 53 and an electrical connection between the first coupling member 23 and the second coupling member 31 is established here.

[0061] In addition, as Figure 8 shown, the second base portion 6 may include a second upper housing 63 and a second lower housing 64. The second upper housing 63 and the second lower housing 64 can be connected to each other, for example, via threaded members and define the internal space of the second base portion 6 with respect to the surrounding environment. The rechargeable battery 4, particularly a lithium battery pack, can be received in the internal space of the second base portion 6. In the illustrated embodiment, the battery 4 may include 6 lithium battery packs connected in parallel with each other, and each lithium battery pack may include six lithium battery cells connected in parallel with each other. For this purpose, the second base portion 6, particularly the second lower housing 64, may include a bearing structure for the lithium battery pack. The bearing structure can divide the internal space of the second base portion 6 into a plurality of, here 6, accommodation areas 65 for one lithium battery pack each. In Figure 8 for the sake of clarity, only two accommodation areas 65 are provided with reference numerals. As Figure 19Most clearly visible, a lath structure 66 that rises from the bottom surface of the second lower housing 64 can be constructed in the accommodation area 65. The battery 4, in particular a lithium battery pack, can be placed on the lath structure 66. The lath structure 66 can include a plurality of laths 67 that extend parallel to each other. In cross-section, each lath 67 together with the bottom surface of the second lower housing 64 can have a substantially Z-shaped cross-section, so that a channel 68 communicating with the surrounding environment can be formed between two adjacent laths 67. The channel 68 can be used, for example, for heat dissipation or for discharging liquid that undesirably enters the second base portion 6. For the sake of clarity here, in Figure 19 only two laths 67 and two channels 68 are provided with reference numerals.

[0062] Returning to Figure 3 and Figure 4 , the first base portion 5 can include a first electrical interface 51, and the second base portion 6 can include a second electrical interface 61 that is arranged in cooperation with the first electrical interface 51. The first base portion 5 and the second base portion 6 can be electrically connected to each other via the first electrical interface 51 and the second electrical interface 61, so that the first base portion 5 can obtain electrical energy from the second base portion 6, in particular the battery 4 located in the second base portion 6, and supply it to the heating appliance 2 installed on the first base portion 5 via the coupler. The first electrical interface 51 can be constructed, for example, as a two-pin or three-pin plug, while the second electrical interface 61 can be correspondingly constructed as a two-pin or three-pin socket. Specifically, as Figure 6 shown, the first lower housing 54 of the first base portion 5 can be constructed with a recess 541, and the first electrical interface 51 can be accommodated in the recess 541. In addition, as can be most clearly seen from Figure 3 and Figure 7 , a protrusion 631 corresponding to the recess 541 can be constructed on the second base portion 6, for example, on the second upper housing 63 of the second base portion 6, and the second electrical interface 61 can be arranged in the protrusion 631. Thus, the electrical connection between the first electrical interface 51 and the second electrical interface 61 can be conveniently established through the shape fit between the recess 541 and the protrusion 63.

[0063] Continuing to refer to Figure 3 and Figure 4, in order to facilitate determining the relative position of the first base part 5 with respect to the second base part 6, the first base part 5 may include a first mechanical interface 52, and the second base part 6 may include a second mechanical interface 62 that is configured to cooperate with the first mechanical interface 52. The first mechanical interface 52 and the second mechanical interface 62 may be configured to define the relative position of the first base part 5 with respect to the second base part 6. Specifically, the first mechanical interface 52 may include at least one, here three positioning bosses 542 that project downward from the first base part 5, and the second mechanical interface 62 may include three positioning recesses 633 provided in the upper surface of the second base part 6 that are configured to cooperate with the three positioning bosses 542. The distances between the three positioning bosses 542 (and correspondingly the three positioning recesses 633) may be different from each other in pairs. Through the cooperation of the three positioning bosses 542 and the three positioning recesses 633, the relative position of the first base part 5 and the second base part 6 can be uniquely defined. In addition, the arrangement structures of the first mechanical interface 52 and the first electrical interface 51 on the first base part 5 and the second mechanical interface 62 and the second electrical interface 61 on the second base part 6 may cooperate with each other such that when the first base part 5 is installed on the second base part 6, the connection between the first electrical interface 51 and the second electrical interface 61 is established simultaneously with the mutual engagement of the first mechanical interface 52 (positioning bosses 542) and the second mechanical interface 62 (positioning recesses 633). Thus, it is possible to conveniently achieve the positioning of the first base part 5 with respect to the second base part 6 and the connection between the first electrical interface 51 and the second electrical interface 61 in only one step. Alternatively, in some other embodiments, it may also be conceivable that the first electrical interface 51 is directly provided in the first mechanical interface 52 (such as a positioning boss) of the first base part 5, and the second electrical interface 61 is directly provided in the second mechanical interface 62 (such as a positioning recess) of the second base part 6.

[0064] In some other embodiments, the positioning recesses may be provided on the first base part 5, while the positioning bosses may be provided on the second base part 6. It is also conceivable that both positioning recesses and positioning bosses are provided on the first base part 5, for example, one positioning recess and two positioning bosses, and correspondingly, one positioning boss and two positioning recesses are provided on the second base part 6.

[0065] In some embodiments, the base 3 may include a locking mechanism that is configured to lock the first base part 5 and the second base part 6 in the relative position in an unlockable manner. The locking mechanism may be configured as a latch mechanism, a snap mechanism, a magnetic attraction mechanism, etc., for example. By providing the locking mechanism, it is convenient to store, use, and move the first base part 5 and the second base part 6 as a whole.

[0066] The following will be combined with Figures 9 to 18A specific embodiment of the locking mechanism is introduced in detail.

[0067] Here, the locking mechanism may mainly include a locking member 7 as shown in Figure 10 and Figure 11 and a mating locking portion 8 constructed on the first base portion 5, particularly in the positioning boss 542 of the first lower housing 54 of the first base portion 5 (see Figures 14 to 17 ). The locking member 7 may be rotatably held on the second base portion 6. The first base portion 5 and the second base portion 6 can be locked to each other through the cooperative action of the locking member 7 and the mating locking portion 8 constructed on the first base portion 5. This will become clear in the following detailed description with reference to the drawings.

[0068] Specifically, as shown in Figure 10 and Figure 11 , the locking member 7 may include a T-shaped pin 71 and a manipulation portion 72. The T-shaped pin 71 and the manipulation portion 72 can be drivingly connected to each other through a key-slot fit between a key 711 constructed at one end of the T-shaped pin 71 and a slot 721 constructed on the manipulation portion 72. The T-shaped pin 71 may include, for example, a cylindrical shaft 712 and a head 713 constructed at the other end of the shaft 712 opposite to the key 711. The head 713 may include at least one lug 714 radially protruding outwardly, here two radially opposed lugs 714. The manipulation portion 72 may be substantially constructed in the shape of a knob and thus has a disc-shaped body 721 and a gripping portion 722 constructed on the disc-shaped body 721. A tubular flange 723 is constructed on the side of the disc-shaped body 721 opposite to the gripping portion 722, and the slot 721 may be constructed in the tubular flange 723.

[0069] The installation of the locking member 7 on the second base portion 6 is described below with reference to Figure 12 and Figure 13 . As shown in Figure 13 , the manipulation portion 72 can pass through a through hole constructed in the second lower housing 64 of the second base portion 6 from the lower side thereof with its tubular flange 723, and the disc-shaped body 721 of the manipulation portion 72 can abut against the outer side or the lower side of the second lower housing 64. As shown in Figure 12As shown, the T-shaped pin 71 can pass through a through hole 632 formed in the second upper housing 63 of the second base portion 6 from the upper side of the second base portion 6 with its shaft 712. Here, the through hole 632 can be formed, in particular, in a positioning recess 633 that exists as the second mechanical interface 62 of the second base portion 6. The cross-section of the through hole 632 can be configured to fit the shaft 712 of the T-shaped pin 71, so that only the shaft 712 can pass through the through hole 632, while the head 713 of the T-shaped pin 71 cannot pass through the through hole 632. In the internal space of the second base portion 6, the key 711 of the T-shaped pin 71 can cooperate with the groove 721 of the operating portion 72 and be in a driving connection, so that, for example, the T-shaped pin 71 can be rotated by grasping and rotating the operating portion 72 from the lower side of the second base portion 6. If necessary, the T-shaped pin 71 can be adhesively connected to the operating portion 72, for example. Figure 7 and Figure 13 Fig. Figure 7 shows the state where the locking member 7 is installed on the second base portion 6. It can be seen that the head 713 of the T-shaped pin 71 and a part of the shaft 712 are exposed from the bottom surface of the positioning recess 633.

[0070] The following will describe the cooperation of the locking member 7 rotatably held on the second base portion 6 with the mating locking portion 8 formed in the positioning boss 542 of the first base portion 5 with reference to Figures 14 to 17 Fig. Figures 14 to 17 . Among them, Figure 14 Fig. Figure 14 schematically shows the upper side of the first lower housing 54 of the first base portion 5, which is located in the internal space of the first base portion 5 in the assembled state. Figure 15 Fig. Figure 15 schematically shows the lower side of the first lower housing 54 of the first base portion 5, which faces away from the internal space of the first base portion 5 in the assembled state. Figure 16 and Figure 17 Figs. Figure 16 and Figure 17 show partial parts of the first lower housing 54. It can be clearly seen that the mating locking portion 8 includes an opening 81, and the opening 81 can have a cross-sectional shape corresponding to the head 713 of the T-shaped pin 71, so that the head 713 (and a part of the shaft 712) of the T-shaped pin 71 can pass through the opening 81 from below. This can occur, for example, when the first base portion 5 is placed on the second base portion 6, so that the positioning boss 542 is inserted into the positioning recess 633. Subsequently, the locking member 7 can be rotated clockwise, for example, to the position shown in Figure 17 Fig. Figure 17 to prevent the head 713 of the T-shaped pin 71 from disengaging from the opening 81 again, thereby realizing the locking of the first base portion 5 and the second base portion 6. Here, the two lugs 714 of the locking member 7 can be respectively received in the stepped portions 82 on both sides of the opening 81. In addition, at least one circumferential stop 83 can be formed in the mating locking portion 8, which is used to limit the degree of rotation of the locking member 7. Figure 18The state after the first base portion 5 and the second base portion 6 are locked to each other by the locking member 7 is shown. Here, for the sake of clarity, only the first lower housing 54 of the first base portion 5 is shown.

[0071] In the illustrated embodiment, a locking mechanism composed of the locking member 7 and the mating locking portion 8 can be respectively provided in the regions of each positioning boss 542 and the corresponding positioning recess 633. Thus, the number of locking mechanisms can be the same as the number of the positioning bosses 542 and the corresponding positioning recesses 633. In some other embodiments, it is also conceivable that the locking mechanism is provided only in the regions of a part of the positioning bosses 542 and the corresponding positioning recesses 633, for example, only one locking mechanism is provided in the region of one positioning boss 542 and the corresponding positioning recess 633.

[0072] Figure 20 The control system circuit diagram of the heating device 1 according to an embodiment of the present application is schematically shown. The heating device 1 may include a control device 10, and the control device 10 may be provided, for example, in the base 3 (such as the first base portion 5 and / or the second base portion 6). The control device 10 may be configured to adjust the operating gear of the heating device 1, for example, to adjust the output power of the rechargeable battery 4 and / or the heating power of the heating assembly 20. The control device 10 may include a battery protection board, especially a lithium battery protection board, which can realize functions such as overcharge protection, over-discharge protection, over-current protection, short-circuit protection, temperature protection, balancing and state detection of the battery.

[0073] In some embodiments, the heating device 1, especially the heating appliance 2, may include a temperature sensor 50 and / or a pressure sensor 60. The temperature sensor 50 may be provided, for example, near the heating assembly 20 of the heating appliance 2 and / or on the first coupling member 23 of the heating appliance 2. The pressure sensor 60 may be provided, for example, in the container 21 of the heating appliance 2 to measure the pressure in the container 21. The control device 10 can be signal-connected to the temperature sensor 50 and / or the pressure sensor 60 via a coupler between the heating appliance 2 and the base 3. The control device 10 may be configured to adjust the output power of the battery 4 or the heating power of the heating assembly 20 according to the sensor signals of the temperature sensor 50 and / or the pressure sensor 60. Thus, on the one hand, the heating temperature of the heating device 1 can be targeted to achieve different functions. On the other hand, dry burning of the heating device 1 can be prevented, and the use safety of the heating device 1 can be improved.

[0074] In addition, in some embodiments, the heating device 1 may include an operation panel 30. The operation panel 30 may be provided on the heating appliance 2 or the base 3, such as the first base portion 5. The operation panel 30 may be electrically connected to the control device 10 so as to turn on or off the heating device 1 and select the operating gear of the heating device 1 via the operation panel 30, etc.

[0075] In some embodiments, the heating device 1 may include at least one of the following operating gears: a first gear, in which the temperature is maintained in a first temperature range, such as between 45 degrees Celsius and 55 degrees Celsius, thereby realizing, for example, a heat preservation function; a second gear, in which the temperature is maintained in a second temperature range, such as between 65 and 75 degrees Celsius, thereby realizing, for example, a heat preservation function at a higher temperature; a third gear, in which it operates at the maximum power for a predetermined period of time, such as 10 minutes to 30 minutes, preferably 15 minutes, thereby realizing, for example, a boiling function; a fourth gear, in which it operates continuously at the maximum power.

[0076] Not limited to the above embodiments, it is also conceivable that the operating gear or the operating mode of the heating device 1 can be changed according to the type of the heating appliance 2 placed on the base 3. For example, when the heating appliance 2 placed on the base 3 is in the form of a kettle, the heating device 1 may operate in a first operating mode, in which the heating device 1 includes the above four operating gears in the first operating mode. When the heating appliance 2 placed on the base 3 is in the form of a frying pan, the heating device 1 may operate in a second operating mode, in which the heating device 1 may, for example, only include the third gear and the fourth gear among the above four operating gears in the second operating mode. Thus, the heating device 1 can adaptively adjust its operating mode according to the heating appliance 2 used to better meet the functional requirements corresponding to the heating appliance 2. For this purpose, the heating device 1 may, for example, include a heating appliance sensor 40, which may be provided on the base 3 to identify the type of the heating appliance 2 placed on the base 3. In some embodiments, the heating appliance sensor 40 may be configured as an RFID / NFC reader. Correspondingly, an RFID / NFC chip may be included on the heating appliance 2.

[0077] In some embodiments, the heating device 1 may include a heat recovery device 70. The heat recovery device 70 may be configured to charge the rechargeable battery 4 by recovering dissipated heat during the use of the heating device 1. To this end, the heat recovery device 70 may be disposed in the heating appliance 2, for example, near the heating assembly 20. Alternatively, the heat recovery device 70 may also be disposed in the base 3, for example, in a region of the base 3 near the heating assembly 20 of the heating appliance 2. The heat recovery device 70 may convert a temperature difference into a voltage, for example, by means of the thermoelectric effect, and the generated voltage may be used to charge the rechargeable battery 4 or directly supply power to the heating device 1. In some embodiments, the heat recovery device 70 may include, for example, a thermoelectric semiconductor and / or a thermocouple, etc. Thereby, the energy utilization rate of the heating device 1 can be advantageously improved, and the endurance of the heating device 1 can be increased.

[0078] In some embodiments, the heating device may include a heat insulation device disposed in the base 3 and / or the heating appliance 2. The heat insulation device may be implemented, for example, as a heat insulation pad made of heat insulation material, a vacuum heat insulation layer, a reflective heat insulation layer, etc. Specifically, as Figure 3 and Figure 4 shown, heat insulation materials such as ceramic fiber, mineral wool, calcium silicate board, etc. may be filled in the lower part 22 of the heating appliance 2, for example, in a region of the heating assembly 2 facing away from the container 21. Alternatively or additionally, heat insulation materials may also be filled around the recess 531 in the first base portion 5. Thereby, the heating efficiency of the heating device 1 can be further improved.

[0079] In addition, in some embodiments, as Figure 2 shown, the base 3, for example, the second base portion 6 including the battery 4, may include a charging interface 32, and the charging interface 32 may be configured to charge the battery 4.

[0080] In some embodiments, the base 3 may further include, for example, an external power supply interface (not shown), which may be configured to connect to an external power supply so as to power the heating device 1 through the external power supply instead of the rechargeable battery 4 located in the base 3. The external power supply may be, for example, a mobile power supply, a vehicle-mounted power supply, or a household power grid. The mobile power supply may also include, for example, a lithium battery pack. In some embodiments, the charging interface 32 and the external power supply interface may be configured as the same external electrical interface. Here, the control device 10 of the heating device 1 may, for example, make a selection based on the operating conditions of the heating device 1 (such as whether the heating device 1 is started, the current operating mode or working gear of the heating device 1, the remaining power of the battery 4, etc.) and the object connected via this external electrical interface (such as whether it is a mobile power supply, a vehicle-mounted power supply, or a household power grid): whether to use the electrical energy from the external electrical interface to directly power the heating device 1 or to charge the rechargeable battery 4. In other embodiments, the external power supply interface (not shown) may be provided on the first base portion 5. The first base portion 5 may be connected to an external power supply via the external power supply interface, so that the first base portion 5 can be used independently of the second base portion 6.

[0081] Not limited to the two-piece configuration of the base 3 described above in conjunction with the drawings, a one-piece configuration of the base 3 is also feasible. Each of the details and features of the heating device 1 described above can be correspondingly applied to the one-piece configuration of the base 3.

[0082] This application also relates to a heating device kit, which may include the above-described heating device 1 and at least one additional heating appliance. The at least one additional heating appliance may, for example, have a different category or form of container 21 from the heating appliance 2 of the heating device 1 shown in the drawings. The at least one additional heating appliance may be used on the base 3 instead of the heating appliance 2 shown in the drawings.

[0083] In addition, the heating device kit may further include at least one mobile power supply. The at least one mobile power supply may be used to supply power instead of the battery 4 located, for example, in the second base portion 6.
