Detailed Implementation

[0041] To make the objectives, technical solutions, and effects of this utility model clearer and more explicit, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0042] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0043] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0044] In existing technologies, the conveying of seasonings relies on liquid pumps. Because different seasonings have different viscosities, different pumps are used. For high-viscosity liquids, such as styrofoam, ordinary liquid pumps are incapable of pumping them. Therefore, using liquid pumps cannot meet the conveying requirements of all seasonings. Furthermore, when using liquid pumps, the starting and stopping speeds of the motor vary significantly, resulting in large differences in the liquid output flow rate. Therefore, to achieve quantitative conveying, an auxiliary flow meter is required.

[0045] Complex seasoning liquids make contact flow meters prone to clogging or reduced accuracy due to liquid adhesion, while non-contact flow meters are complex in structure and expensive (thousands to tens of thousands), making them difficult to apply to civilian products.

[0046] In view of the above-mentioned problems in the prior art, the present invention provides a liquid seasoning conveying device, such as... Figure 1 and Figure 2As shown, the liquid seasoning conveying device includes: a cabinet 100; seasoning tanks 200, several seasoning tanks 200 being detachably installed inside the cabinet 100, each seasoning tank 200 having a liquid outlet 210 and a pressurizing port 220; a conveying assembly 300, the conveying assembly 300 including several conveying pipes 320 connected one-to-one with the several liquid outlets 210, each conveying pipe 320 having a control valve 310 at its end; a pressurizing assembly 400, the pressurizing assembly 400 including a high-pressure gas cylinder 410 and a pressurizing pipe 420, the high-pressure gas cylinder 410 being airtightly connected to the pressurizing pipe 420 via a pressure reducing valve, the output end of the pressurizing pipe 420 being airtightly connected to the several pressurizing ports 220; and a control assembly 500, the control assembly 500 being signal-connected to the control valve 310.

[0047] This invention uses a pressurizing component 400 to pressurize the liquid in the seasoning tank 200, giving the liquid in the seasoning tank 200 a certain potential energy. Under the action of this potential energy, the liquid in the seasoning tank 200 flows out through the delivery pipe 320. By maintaining a stable air pressure in the seasoning tank 200, the liquid in the delivery pipe 320 can flow at a uniform speed. Under these conditions, the control component 500 controls the opening and closing time of the control valve 310 at the end of the delivery pipe 320, which can accurately control the output dosage of the liquid without the need for complicated flow meter measurements, thereby realizing pumpless delivery and dosage control of liquid seasonings.

[0048] In the above embodiments, such as Figure 1 and Figure 2 As shown, the main body of the liquid seasoning conveying device of this utility model consists of a cabinet 100, a seasoning tank 200, a conveying component 300, a pressurizing component 400, and a control component 500.

[0049] In this embodiment, several seasoning containers 200 are provided, each filled with liquid seasoning. The seasoning containers 200 are detachably installed inside the cabinet 100 for easy replacement. The conveying assembly 300 is used to output the liquid seasoning from the seasoning containers 200 to a predetermined position to enable cooperation with other cooking equipment, such as stoves and automatic cooking machines. The pressurizing assembly 400 pressurizes the interior of the seasoning containers 200 with gas.

[0050] In this embodiment, the conveying assembly 300 specifically includes a plurality of conveying pipes 320 each equipped with a control valve 310. The front ends of the plurality of conveying pipes 320 are liquid-tightly connected to the liquid outlets 210 of a plurality of seasoning tanks 200, and the ends of the plurality of conveying pipes 320 are liquid-tightly connected to a plurality of control valves 310. The plurality of control valves 310 are fixed to a valve bracket 600 (e.g., Figure 3 As shown, a plurality of control valves 310 protrude from one side of the cabinet 100; the control valves 310 control the opening or closing of the liquid in the delivery pipe 320.

[0051] In this embodiment, as Figure 3 As shown, to facilitate integration with other automated cooking equipment, a valve bracket 600 protrudes from one side of the cabinet 100. Several control valves 310 are mounted on the protruding valve bracket 600. The protruding valve bracket 600 can be inserted into other automated cooking equipment to facilitate the timely addition of accurate amounts of seasoning liquid to the cooking pot.

[0052] In this embodiment, as Figure 2 and Figure 5 As shown, the pressurization assembly 400 specifically includes a pressurization pipe 420 and a high-pressure gas cylinder 410. The pressurization pipe 420 is airtightly connected to the pressurization port 220 on the aforementioned several seasoning tanks 200. The high-pressure gas cylinder 410 is installed inside the cabinet 100 and is airtightly connected to the pressurization pipe 420. The pressurization assembly 400 is used to pressurize the interior of the several seasoning tanks 200 so that the liquid inside has a certain potential energy. Under the action of this potential energy, the liquid inside the seasoning tanks 200 flows out through the delivery pipe 320, completing pump-free delivery.

[0053] In another feasible embodiment, an external gas source can be used instead of the high-pressure gas cylinder 410.

[0054] Specifically, in one embodiment, the high-pressure gas cylinder 410 is filled with liquid carbon dioxide, nitrogen, or other food-grade gases. In this embodiment, a pressure reducing valve is provided at the output port of the high-pressure gas cylinder 410, and the required output pressure can be adjusted by adjusting the pressure reducing valve. The output of the pressure reducing valve is airtightly connected to the pressure boosting pipe 420, and the other end of the pressure boosting pipe 420 is airtightly connected to the pressure boosting ports 220 of several condiment tanks 200, so that a certain gas pressure is formed on the liquid surface of the condiment tanks 200. Under the action of this gas pressure, the liquid in the condiment tanks 200 has a certain potential energy.

[0055] In addition, a pressure sensor is installed on the aforementioned booster pipe 420. The pressure sensor is used to measure the air pressure value inside the booster pipe 420. The flow rate and the potential energy of the liquid in the seasoning tank 200 are also related to the air pressure inside the booster pipe 420. The air pressure value is one of the parameters used by the control component 500 to calculate the opening and closing time of the control valve 310.

[0056] like Figure 4 As shown, a liquid level sensor 520 is installed on the condiment tank 200. The liquid level sensor 520 is used to monitor the remaining amount of liquid condiment in the condiment tank 200. The liquid level sensor 520 is connected to the control component 500 and can remind the user to replenish the liquid condiment. In this embodiment, the liquid level sensor 520 is a weighing sensor, which calculates the remaining amount of liquid in the condiment tank 200 by the weight value generated by the replacement ratio of pressurized gas and liquid.

[0057] A heater is installed inside the cabinet 100. The heater is connected to the control component 500 by a signal. The heater is used to heat the inside of the cabinet 100 to prevent the liquid seasoning from solidifying in a low-temperature environment. When the ambient temperature rises to a certain temperature, the heater automatically stops heating.

[0058] A temperature sensor is also installed inside the cabinet 100. The temperature sensor is connected to the control component 500 to detect the ambient temperature of the liquid seasoning and send the temperature signal to the control component 500. In some cases, the control component 500 can activate the heater to maintain the liquefied state of the seasoning and compensate for the flow error caused by the change in the viscosity of the seasoning liquid at different temperatures.

[0059] In this embodiment, as Figure 6 As shown, the control unit 500 also includes a display 510, which displays information such as the currently open control valve 310, the pressure of the booster pipe 420, the temperature inside the cabinet, and the current balance of the seasoning container 200. The controller is equipped with external wired and wireless interfaces, through which other cooking equipment can control this device to complete the delivery of liquid seasonings in the required dosage.

[0060] In another possible embodiment of this utility model, such as Figure 1 and Figure 3 As shown, the cabinet 100 includes a cabinet 100, a front panel 120, a support plate 140, and a base 150. The front panel 120 is located on one side of the cabinet 100, and the controller is embedded in the front panel 120. Users can use wired or wireless interfaces to connect with other cooking equipment, or they can manually operate it using the operation panel on the display 510. A significant advantage of manual operation is that it allows for independent calibration and on-site correction of the flow control of each valve.

[0061] The support plate 140 has multiple layers, with the layer height determined according to the height of the seasoning tanks 200. Several liquid level sensors 520 are installed on the support plate 140, several bases 150 are installed on the liquid level sensors 520, and several seasoning tanks 200 are placed on the bases 150 respectively. Several interfaces of conveying pipes 320 and several interfaces of pressurizing pipes 420 are also provided on the support plate 140. Several seasoning tanks 200 are respectively connected to the conveying pipes 320 in a liquid-tight manner through one-way valves, and connected to the pressurizing pipes 420 in an airtight manner through one-way valves.

[0062] The liquid level sensor 520 is a weighing sensor, which is located between the support plate 140 and the base 150.

[0063] Furthermore, such as Figure 4As shown, a base 150 is provided above the liquid level sensor 520 to stably place the condiment container 200. The bottom of the base 150 is fixedly connected to the liquid level sensor 520, and the condiment container 200 is detachably mounted on the base 150, thereby achieving stable placement of the condiment container 200. The weight of the condiment container 200 is measured in real time by the liquid level sensor 520. The pressurized gas inside the condiment container 200 also has a certain weight. The control component 500 can calculate the actual weight of the remaining liquid in the condiment container 200. When the liquid level reaches the warning level, a warning is issued in time, and the staff can replace the condiment container 200 or replenish it with the corresponding condiments in a timely manner.

[0064] Furthermore, such as Figure 1 and Figure 2 As shown, the cabinet 100 also includes a rear panel 130 and a sealing door 160; the rear panel 130 is located on the rear side of the cabinet 100 and can be used to protect the seasoning jar 200 inside the cabinet 100; the sealing door 160 is located on both sides of the cabinet 100 and is connected to the cabinet 100 by a hinge 163, which makes it convenient to replace the seasoning jar 200 when opened and prevents pests from entering when closed.

[0065] In this embodiment, a sealing strip 161 is provided on the sealing door 160 to ensure the sealing performance when the sealing door 160 is closed, thereby effectively preventing pests from entering. In addition, a handle 162 is also provided to facilitate the user to open or close the door.

[0066] Furthermore, such as Figure 2 As shown, a protective shell is provided outside several conveying pipes 320 and control valves 310. The protective shell is sealed to the cabinet 100 to prevent dust accumulation on the conveying pipes 320 and control valves 310, and to prevent pests such as cockroaches and rats from entering.

[0067] A valve bracket 600 is provided inside the aforementioned protective housing. One end of the valve bracket 600 is fixedly connected to the aforementioned protective housing, and a plurality of control valves 310 are distributed and installed on it. In this embodiment, in order to ensure the accuracy of the dosage of seasoning, it is preferable to set the control valves 310 at the end of the delivery pipe 320. Another advantage of this setting is that it can reduce the liquid residue at the port of the delivery pipe 320, thereby ensuring hygiene. Based on this embodiment, a plurality of control valves 310 are fixedly connected to the bracket.

[0068] In another possible embodiment of this utility model, such as Figure 6As shown, the control component 500 specifically includes a display 510, which has a display function and can display information such as the on / off status of several control valves 310, the pressure of the booster pipe 420, the temperature inside the cabinet, and the current balance of the seasoning tank 200, so that the staff can replace or add seasonings in a timely manner. In this embodiment, the staff can manually operate the on / off switches of different control valves 310 on the control panel of the display 510. During the first use, residual air in the delivery pipe 320 can be removed. Another necessary operation is to manually switch the control valves 310 and correct delivery errors by weighing the actual delivered liquid.
