[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0021] Please refer to Figures 1 - 4 As shown in the figure, the present invention provides the following technical solutions: A dish warming table, comprising: a protective glass 1 on the top of the warming table, an RFID reader / writer 2 is installed below the protective glass 1 on the top of the warming table, a display screen 3 is installed on one side of the RFID reader / writer 2, a switch 4 is installed between the RFID reader / writer 2 and the display screen 3, a power supply box 5 is installed on the switch 4, an outmeal induction placement area 12 is provided above the RFID reader / writer 2, a heating module 10 is provided above the outmeal induction placement area 12, and a capacitive touch screen 15 is connected to one side of the display screen 3.
[0022] Through the above technical solutions:
[0023] During use, place the prepared dishes in the outmeal induction placement area 12. The RFID reader / writer 2 below reads the dish information and transmits the information to the display screen 3 through the switch 4. The power supply box 5 can ensure the normal power supply of the display screen 3 and improve the stability of the device. The display screen 3 displays the dish name and unit price in real time. The capacitive touch screen 15 can confirm the dish information, so that the tableware does not need to be classified, and the correspondence between the dishes and the tableware can be completed in time, greatly improving the work efficiency. The heating module 10 ensures that when the food stays in the outmeal induction placement area 12, the temperature is not easily lost in large amounts, thus ensuring the temperature of the food and bringing a good experience to the customers. And in order to prevent users from accidentally scalding during use, heat insulation treatment is usually performed on the outer shell and operation panel of the warming table to ensure that the appearance part remains within the safe temperature range.
[0024] Please refer to Figures 1 - 4As shown in the figure, a vegetable basin 16 is provided below the top protection glass 1 of the warming table. The bottom end of the vegetable basin 16 is supported by a bottom stainless steel casing 17. A heating water basin 23 is installed below the vegetable basin 16. A temperature control panel 18 is provided outside the heating water basin 23. An electrical box 19 is connected to the temperature control panel 18. A water valve assembly is installed on the heating water basin 23.
[0025] Further, the water valve assembly includes a water supply solenoid valve 20, a first water valve 21, and a second water valve 22. The water supply solenoid valve 20 is installed on the liquid inlet end of the heating water basin 23. The first water valve 21 is connected to the liquid inlet end of the water supply solenoid valve 20. The second water valve 22 is installed on the liquid outlet end of the heating water basin 23.
[0026] Through the above technical solutions:
[0027] During use, turn on the power to activate the heating system. The built-in temperature sensor starts to monitor the temperature of the tabletop to ensure that it reaches and maintains the temperature set by the user. Various dishes are placed in the vegetable basin 16. An electric heating wire or a heating plate is installed in the heating water basin 23 as a heat source. Open the water supply solenoid valve 20 and the first water valve 21 so that water flows into the heating water basin 23. Utilize the conversion of water into water vapor to heat the vegetable basin 16 through the water vapor to ensure the temperature of the food. The warming table is also equipped with a temperature control panel 18, which can set and adjust the temperature as needed to ensure that the food is maintained within a suitable temperature range. Moreover, using water vapor heating can also prevent the food from drying out excessively. Once the set temperature is reached, the system will enter the maintenance mode, adjusting the heating power to maintain the current temperature and prevent overheating or cooling. If the temperature does not reach the set value, it will continue to heat and periodically detect the current temperature until the target is reached. During this process, the water vapor is evenly distributed into each grid to ensure that all the food can be evenly kept warm.
[0028] Further, please refer to Figures 1 - 5 As shown in the figure, a lamp board 14 is installed on one side of the RFID reader 2. A lamp control board 13 is installed on the lamp board 14. A lamp control component is connected to the lamp control board 13.
[0029] Further, the lamp control component includes a constant-on lamp switch 8, a temperature-controlled lamp adjustment switch 9, a constant-on lamp body 11, and a temperature-controlled lamp body 25. The constant-on lamp switch 8 and the temperature-controlled lamp adjustment switch 9 are installed on the side wall of the top protection glass 1 of the warming table. The constant-on lamp body 11 and the temperature-controlled lamp body 25 are installed on the lower end surface of the top protection glass 1 of the warming table.
[0030] Specifically, the lamp board 14 facilitates the installation of the lamp control component. The constant-on lamp switch 8 and the temperature-controlled lamp adjustment switch 9 respectively control the constant-on lamp body 11 and the temperature-controlled lamp body 25. The constant-on lamp body 11 can serve as the main light source to provide stable lighting. The temperature-controlled lamp body 25 can be adjusted to the optimal temperature according to different environments, thereby providing a stable lighting effect.
[0031] Further, please refer to Figures 1 - 4 As shown, a protective saliva shield 6 is provided above the vegetable basin 16, and a meal tray 7 is installed on one side of the vegetable basin 16. A folding mechanism 24 is connected to the bottom end of the meal tray 7.
[0032] Specifically, the protective saliva shield 6 can prevent saliva from being sprayed on the dishes when the customer is speaking. The meal tray 7 facilitates supporting the dinner plate, and a folding mechanism 24 is connected to the bottom of the meal tray 7, which can save space when not in use.
[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
