Description

Technical Field

[0001] The utility model relates to an oil supply device. Background Art

[0002] In recent years, a number of cooking robots have been introduced in the market, bringing great convenience to restaurants. When a cooking robot is working, it is necessary to quantitatively add edible oil to a frying pan, especially some dishes need to add lard. Since lard is easy to solidify, it is necessary to keep it warm or heat it up.

[0003] Chinese Patent with the publication number of CN 218791818 U discloses an edible oil adding mechanism and a cooking machine. In this solution, a power pump is used to drive the flow of a heat preservation medium in a circulation pipeline to provide a heat source for an oil delivery pipe to prevent lard from solidifying. However, for the circulation of the heat preservation medium, a liquid pump is required, resulting in a high cost, and strict pipeline sealing is required for the medium circulation, making the overall structure relatively complex.

[0004] Therefore, it is necessary to design a new oil supply device. Summary of the Utility Model

Detailed implementation mode

[0031] The following will further elaborate on the present utility model in conjunction with the attached drawings and specific embodiments:

[0032] Embodiment 1: As Figures 1-6 shown, an oil supply device includes a water tank 201 and two sets of oil supply mechanisms. Preferably, one supplies lard and the other supplies vegetable oil (or blended oil); the oil supply mechanism includes a fuel tank 216, an oil pump 206, an oil pipe 210, and a fuel injector 209;

[0033] The fuel tank is placed in the water tank. A heating pipe is provided in the water tank for heating the water; the hot water in the water tank provides a constant temperature environment for the fuel tank; the constant temperature heating tape is responsible for heating the oil pipeline, and cooperates with the heat-insulating cotton sleeve to provide a constant temperature environment for the oil pipeline; the constant temperature means that the temperature is within a certain range, such as within the range of 30 - 50 degrees, to prevent the lard from solidifying.

[0034] The oil pump is arranged on the water tank. The oil pump is connected to the fuel injector through the oil pipe. The oil pump is used to pump the oil in the fuel tank through the oil pipe to the fuel injector. The fuel injectors of the two oil supply mechanisms are arranged side by side.

[0035] It further includes a heat-insulating cotton sleeve 208; the oil pipes of the two oil supply mechanisms are all placed in the heat-insulating cotton sleeve.

[0036] A heating tape 207 is provided in the heat-insulating cotton sleeve; the heating tape is mounted (laid flat) or wound around the oil pipe.

[0037] The water tank is a constant temperature water tank; two heating pipes 212 are provided on the water tank, and the heating pipes extend into the water tank; a water temperature sensor is also provided on the water tank.

[0038] The water tank is a constant temperature water tank; a water level detection pipe 211 is provided on the side of the water tank, and a non-contact liquid level sensor 205 is provided on the water level detection pipe, or a photoelectric sensor is installed on the side of the water tank to detect the water level.

[0039] The oil pump is fixed on the side of the water tank.

[0040] A water tank cap 203 is provided on the top of the water tank, and a drain port 215 is provided at the bottom or side of the water tank. The water tank cap can be opened to add tap water, and the drain port is used to drain the tap water during cleaning and maintenance.

[0041] A fuel tank cover 202 is provided at the top of the fuel tank; an oil drain port 214 is provided at the side of the fuel tank. Opening the fuel tank cover allows edible oil to be added into the fuel tank. When necessary, opening the oil drain port can drain the edible oil in the fuel tank.

[0042] Description of the overall structure and working process:

[0043] Two fuel tanks are evenly arranged in the water tank. Tap water is added into the water tank, and the tap water surrounds the fuel tanks. A non-contact liquid level sensor is installed on the water tank. The non-contact liquid level sensor is used to detect the liquid level height in the water tank. Further, an optoelectronic sensor can be adopted to detect the water level as redundant detection. Two heating tubes with the same power are evenly arranged near the bottom of the water tank. The heating tubes are powered on to heat the tap water. A temperature sensor detects the water temperature in the water tank in real time and feeds it back to the system. The system controls the heating time of the heating tubes to control the water temperature in the water tank. The tap water heated by the heating tubes transfers heat to heat the edible oil in the fuel tank, so as to ensure that the edible oil in the fuel tank is in a liquid state and can be transported through an oil pump. The oil in the fuel tank is absorbed by the pump and then transmitted through an oil pipeline to the fuel injector for spraying. The outside of the oil pipeline is closely attached (by means of laying flat or winding) with a constant temperature heating belt (or heating strip). The constant temperature heating belt can ensure that the oil in the oil pipeline is in a liquid state during the oil transportation process. The outside of the oil pipeline and the constant temperature heating belt are tightly wrapped with heat insulation cotton (i.e., a heat insulation cotton sleeve) to prevent heat dissipation, ensure the constant temperature of the oil pipeline, and reduce energy consumption at the same time.

[0044] Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
