Description

Technical Field

[0001] The present invention relates to the technical field of electric heating appliances, in particular to a heating electric steaming appliance. Background Art

[0002] Existing electric steaming appliances, such as electric steamers, come in a variety of structures and styles. For example, Chinese Utility Model Patent Grant No. CN203041835U, published on July 10, 2013, discloses a "steam reheating structure for an electric steaming appliance." The structure comprises a housing with a steam chamber, a steaming appliance positioned above the steam chamber, and a plurality of steam outlets formed at the top of the steam chamber, which communicate with the interior of the electric steaming appliance. A heating pipe is also located within the steam chamber for secondary steam heating. This electric steaming appliance utilizes the heating pipes within the same steam chamber to reheat the high-temperature steam generated (i.e., secondary heating), thereby achieving a higher steam temperature. This improves the thermal efficiency of the electric steaming appliance and shortens the cooking time, saving both time and energy.

[0003] However, the heating electric steamer of the above structure still has the following shortcomings: (1) Since the two heating elements (heating plate assembly and heating tube) are both arranged on the same base (housing), the two heating elements heat at the same time, and the temperature inside the base is very high, which can easily cause damage to other electrical accessories inside the base; (2) In order to accommodate the placement of the two heating elements, the base will be larger in size, which is not conducive to packaging and transportation; (3) Since the heating plate assembly of the preheating device (one-time heating) is fixed on the bottom wall of the steam chamber, it is affected by the large amount of water stored in the steam chamber, and the time required for one-time heating is longer. Moreover, the preheating device uses a heating plate assembly, which is more expensive; (4) During the heating operation, water cannot be injected into the steam chamber, which cannot meet the different usage needs of users. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a heating electric steaming device that significantly reduces the temperature inside the seat, has a small overall volume, a low-cost preheating device, heats quickly, and can supply water to the steam seat during heating.

[0005] The object of the present invention is achieved like this:

[0006] A heating electric steaming appliance comprises a main base and a steam base, the main base being movably connected to the steam base, the main base being provided with a water inlet pipe, a preheating device and a heat-conducting water outlet pipe, the steam base being provided with a hot water inlet, a steam generating disk and a steam outlet, the heat-conducting water outlet pipe being connected to the hot water inlet, the preheating device comprising a water pipe and an electric heating pipe, the two ends of the water pipe being respectively connected to the water inlet pipe and the heat-conducting water outlet pipe, the electric heating pipe extending along the extension direction of the water pipe and abutting against the outer wall of the water pipe; in this heating electric steaming appliance, the preheating device and the steam generating disk are respectively mounted on different base bodies (the main base) and steam seat), to prevent the two heating elements from being installed on the same seat body and causing the temperature to be too high. Moreover, since the main seat and the steam seat are movably connected, the two seats can be folded up when not in use to reduce the overall volume, which is convenient for packaging and carrying; what is more, the preheating device adopts a method in which the outer wall of the water guide pipe and the outer wall of the electric heating pipe are close to each other and extend side by side, so that the water flowing through the water guide pipe is heated instantly, the heating speed is fast, and the cost of this preheating device is low; what is more, when heating, the preheating device can continuously supply water to the steam seat to meet the heating electric steaming appliance with different usage needs of users.

[0007] The purpose of the present invention can also be solved by the following technical measures:

[0008] As a more specific solution, the water pipe and the electric heating pipe are both U-shaped pipes. The U-shaped water pipe and the U-shaped electric heating pipe can slow down the water speed to extend the heating time of the preheating device and make the temperature of the water leaving the preheating device as high as possible to reduce the secondary heating time. For example, the water temperature leaving the preheating device can reach 80 degrees. In this way, even if water (hot water) is continuously supplied to the steam seat, the steam generating disk can generate steam quickly.

[0009] As a more specific solution, an electromagnetic pump is further provided between the water guide pipe and the water inlet pipe; the electromagnetic pump is added here to control the water flow rate flowing through the preheating device, so as to more accurately control the water temperature coming out of the preheating device.

[0010] As a more specific solution, a water tank is further provided on the main base, a water outlet valve of the water tank is connected to the water inlet pipe, and the water tank is detachably mounted on the main base, so that the user can take out the water tank for adding water or cleaning.

[0011] As a more specific solution, the water outlet valve is arranged at the bottom of the water tank, and the water tank is placed on the top of the main engine base, so that the water in the water tank flows from the bottom water outlet valve into the main engine base below.

[0012] As a more specific solution, the heat conduction water outlet pipe and the hot water inlet are connected by a soft connecting pipe. The two ends of the soft connecting pipe are easy to connect and disassemble with the heat conduction water outlet pipe and the hot water inlet, and are conducive to the movable connection between the main base and the steam base.

[0013] As a more specific solution, the steam generating plate includes a heating plate and a nozzle. The nozzle passes through the heating plate from bottom to top, the lower end of the nozzle serves as a hot water inlet, and the upper end extends upward from the heating plate to the steam outlet. When the hot water coming out of the main base passes through the nozzle quickly, it is heated by the heating plate at the same time. Part of the hot water is vaporized after heating, and the steam is ejected through the outlet at the upper end of the nozzle and then discharged through the steam outlet to be used for heating the steam layer. Since the nozzle has a small diameter, the water flowing through the nozzle is quickly heated by the heating plate, so that the hot water vaporizes quickly, thereby improving work efficiency.

[0014] As a more specific solution, a steam chamber is provided on the steam seat, the heating plate is placed in the steam chamber, the steam outlet is opened on the top wall of the steam chamber, and the upper end of the nozzle extends to the upper part of the steam chamber close to the steam outlet; when the hot water coming out of the main seat passes through the nozzle, part of the hot water is vaporized after heating and the steam is ejected through the outlet at the upper end of the nozzle, and part of the hot water is heated (failed to be vaporized) and ejected through the outlet at the upper end of the nozzle, and the hot water flows back to the steam chamber, and the heating plate quickly heats the hot water in the steam chamber, and the hot water in the steam chamber is vaporized after heating to form steam, and the steam is discharged through the steam outlet for use in heating the steam layer. The entire heating and vaporization process is rapid, and the steam is continuously discharged through the steam outlet.

[0015] As a more specific solution, a timing switch is also included. The timing switch is arranged on the main base. The timing switch is electrically connected to the preheating device and the steam generating disk respectively. The user can set the heating time of the preheating device and the steam generating disk through the timing switch to control the start and stop of the preheating device and the steam generating disk.

[0016] As a more specific solution, heat dissipation windows are respectively provided on the main base and the steam base. The preheating device dissipates heat through the heat dissipation windows of the main base, and the steam generating disk dissipates heat through the heat dissipation windows of the steam base, thereby realizing independent heat dissipation of the preheating device and the steam generating disk without affecting each other.

[0017] The beneficial effects of the present invention are as follows:

[0018] (1) This electric steaming appliance installs the preheating device and the steam generating plate on different bases (main base and steam base) respectively to prevent the two heating elements from being installed on the same base and causing the temperature to be too high. In addition, since the main base and the steam base are movably connected, the two bases can be folded up when not in use to reduce the overall volume, making it convenient to pack and carry. What's more, the preheating device adopts a method in which the outer wall of the water pipe and the outer wall of the electric heating pipe are close to each other and extend side by side, so that the water flowing through the water pipe is heated immediately, the heating speed is fast, and the cost of the preheating device is low. What's more, when heating, the preheating device can continuously send water to the steam base to meet the different needs of users.

[0019] (2) Furthermore, the U-shaped water pipe and the U-shaped electric heating pipe can slow down the water speed to extend the heating time of the preheating device and make the temperature of the water coming out of the preheating device as high as possible to reduce the secondary heating time. For example, the water temperature coming out of the preheating device can reach 80 degrees. In this way, even if water (hot water) is continuously transported into the steam seat, it is guaranteed that the steam generating disk will generate steam quickly.

[0020] (3) In addition, an electromagnetic pump is added between the water guide pipe and the water inlet pipe to control the water flow rate through the preheating device, which can more accurately control the water temperature coming out of the preheating device.

[0021] (4) Since the steam generating plate includes a heating plate and a nozzle, the hot water from the main unit quickly passes through the nozzle and is heated by the heating plate at the same time. Part of the hot water is vaporized after being heated, and the steam is ejected through the outlet at the upper end of the nozzle and then discharged through the steam outlet to be used for heating the steam layer. Since the nozzle has a small diameter, the water flowing through the nozzle is quickly heated by the heating plate, causing the hot water to vaporize quickly, thereby improving work efficiency.

[0022] (5) Moreover, when the hot water from the main unit passes through the nozzle, part of the hot water is heated and vaporized, and the steam is ejected through the outlet at the upper end of the nozzle. Part of the hot water is heated (but fails to vaporize) and ejected through the outlet at the upper end of the nozzle. The hot water flows back to the steam chamber, and the heating plate quickly heats the hot water in the steam chamber. The hot water in the steam chamber is heated and vaporized to form steam, which is discharged through the steam outlet to be used for heating the steam layer. The entire heating and vaporization process is rapid, and steam is continuously discharged through the steam outlet.

[0023] (6) Since heat dissipation windows are respectively provided on the main engine base and the steam base, the preheating device and the steam generating disk dissipate heat through the corresponding heat dissipation windows respectively, thereby realizing independent heat dissipation of the preheating device and the steam generating disk without affecting each other.
