Description

Technical Field

[0001] The utility model relates to the technical field of food equipment, in particular to a heat-insulating and moisture-retaining self-service rice-making machine. Background Art

[0002] Many canteens and restaurants provide consumers with rice as a staple food. In order to reduce the waiting time of consumers, canteens and restaurants generally process rice into cooked rice in advance. When consumers arrive, they do not need to wait for the rice to mature and can eat it directly. However, the arrival time of each consumer is different. In order to allow each consumer to eat fresh and hot rice at any time, the cooked rice needs to be kept warm. At the same time, most traditional canteens and restaurants use manual rice serving, which has the following problems: First, the labor intensity is high and the efficiency is low; second, the amount of rice is difficult to control accurately, and it is easy to have too much or too little rice; third, many people queuing up to serve rice can easily cause rice contamination.

[0003] In order to solve the above problems, people have invented special automatic rice-beating machines. For example, CN113648863A discloses a rice-beating machine, which includes a housing and a rice-loading mechanism, a dispersing mechanism and a rice-dispensing mechanism located in the housing. The rice-loading mechanism, the dispersing mechanism and the rice-dispensing mechanism are connected and arranged in sequence from top to bottom. The rice-loading mechanism includes a rice bucket, a first motor, a first transmission member, a first stirring rod, a water tank and a heater. The rice bucket has a receiving chamber connected to the dispersing mechanism. The water tank is installed on the rice bucket. The heater is located in the water tank. The first motor is fixed on the housing. One end of the first stirring rod is located in the receiving chamber and is rotatably connected to the rice bucket. The other end passes through the rice bucket and is connected to the output end of the first motor through the first transmission member. The invention installs a water tank on the rice bucket. A heater is installed in the water tank. The heater can heat the water in the water tank. The heat can be transferred to the receiving chamber to keep the rice in a hot state. At the same time, the first motor can drive the first stirring rod to rotate, constantly flip the rice, so that the rice is heated evenly and the phenomenon of rice agglomeration is avoided. However, the rice cooker in the invention cannot realize the moisturizing function. After keeping the rice warm for a long time, the rice is likely to lose moisture, thereby causing the rice to be too dry or too hard, affecting the taste of the rice.

[0004] Therefore, it is necessary to improve the existing rice beater and provide an automatic rice beater that can keep the rice warm for a long time and does not make the rice dry and hard. Utility Model Content

[0005] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art and provide a heat-insulating and moisture-retaining self-service rice cooker, which can not only keep the rice warm for a long time, but also adjust the humidity of the rice to prevent the rice from becoming dry and hard, thereby ensuring the good taste of the rice, so that users can enjoy fresh and delicious rice with appropriate temperature and humidity at any time.

[0006] The technical solution of the utility model is: a heat-insulating and moisture-retaining self-service rice-making machine, comprising a rice-making machine body and a moisture-retaining mechanism, wherein the moisture-retaining mechanism comprises a water tank, a water pump, a water pipe, a nozzle, a humidity sensor and a heating plate, wherein the water pump is arranged in the water tank, and the nozzle, the humidity sensor and the heating plate are all arranged inside the rice-making machine body, the nozzle is connected to the water tank through a water pipe, and under the action of the water pump, the water in the water tank flows to the nozzle through the water pipe, and the nozzle sprays the water toward the heating plate, and the heating plate can heat the water and evaporate it into water vapor, and the water vapor contacts the rice stored in the rice-making machine body to increase the humidity of the rice.

[0007] Furthermore, the rice cooker body includes a shell and a main control panel. A receiving tray, a heat preservation mechanism and a conveying mechanism are provided inside the shell. The receiving tray is used to store rice, the conveying mechanism is arranged in the receiving tray, the heat preservation mechanism is used to keep the rice warm, and the conveying mechanism can be used to transport the rice to the outlet of the rice cooker.

[0008] Furthermore, the water pump, the heating plate and the humidity sensor are all connected to the main control board and work together under the control of the main control board.

[0009] Furthermore, a cover plate is provided on the top of the shell, and a humidity sensor is provided on the inner surface of the cover plate, so that the humidity sensor can detect the humidity in the receiving tray in real time and transmit the detection signal to the main control board.

[0010] Furthermore, the water tank is arranged on the outside of the shell, so that there is no need to open the cover when the water tank needs to be filled with water, and adding water is more convenient; preferably, a transparent window is provided on the water tank to facilitate the user to observe the water level in the water tank, and when the water level is too low, it can be discovered and replenished in time.

[0012] Furthermore, the nozzle is arranged outside the receiving tray, the heating plate is arranged below the nozzle, and the receiving tray is provided with air holes for the passage of water vapor. In this way, the nozzle sprays water to the heating plate below, and when the water is evaporated by the heating plate and becomes water vapor, the water vapor can pass through the air holes and quickly contact the rice in the receiving tray, thereby adjusting the humidity of the rice. Preferably, when humidifying the rice, the main shaft of the conveying mechanism can also be rotated to break up and stir the rice to improve the humidification efficiency.

[0013] Furthermore, in some specific embodiments, the heating plate can also directly realize the function of the heat preservation mechanism, that is, the heat preservation mechanism and the heating plate can be of the same structure, so that the structure of the entire rice cooker is more concise. During use, when humidification is not required, the nozzle does not spray water, and the heating plate can only heat to realize the heat preservation function. When the humidity needs to be increased, the nozzle sprays water, and the heating plate heats the water to evaporate and generate water vapor to humidify the rice.

[0014] Furthermore, the spiral blades and the beating rods on the main shaft can be arranged in a staggered manner. For example, only spiral blades or only beating rods can be arranged on the main shaft or a section thereof, so that the corresponding single functions can be realized respectively; or both spiral blades and beating rods can be arranged on the same section of the main shaft, so that the rice can be conveyed and be broken up at the same time.

[0023] The present invention will be further described in detail below in conjunction with specific embodiments. Methods or functional components not specifically described in the embodiments are all prior art. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present invention.

[0024] Example 1

[0025] like Figure 1-6 As shown, the present embodiment is a self-service rice cooker with heat preservation and moisture retention, comprising a rice cooker body and a moisture retention mechanism, wherein the moisture retention mechanism comprises a water tank 3, a water pump, a water pipe 4, a nozzle 5, a humidity sensor 6 and a heating plate 9, wherein the water pump is arranged in the water tank 3, the nozzle 5, the humidity sensor 6 and the heating plate 9 are all arranged inside the rice cooker body, the nozzle 5 is connected to the water tank 3 through the water pipe 4, and under the action of the water pump, the water in the water tank 3 flows through the water pipe 4 to the nozzle 5, and the nozzle 5 sprays the water to the heating plate 9 below, and the heating plate 9 can heat the water and evaporate it into water vapor, and the water vapor contacts the rice stored in the rice cooker body to increase the humidity of the rice.

[0026] In this embodiment, the rice beater body includes a shell 1 and a main control panel. The shell 1 is provided with a receiving tray 8, a heat preservation mechanism and a conveying mechanism 7. The heat preservation mechanism is used to keep the rice warm, and the conveying mechanism 7 can be used to transport the rice to the outlet of the rice beater.

[0027] In this embodiment, the water pump, the heating plate 9 and the humidity sensor 6 are all connected to the main control board and work together under the control of the main control board. A cover plate 2 is provided on the top of the housing 1, and the humidity sensor 6 is provided on the inner surface of the cover plate 2, so that the humidity sensor 6 can detect the humidity in the receiving tray 8 in real time and transmit the detection signal to the main control board.

[0028] In this embodiment, the water tank 3 is arranged on the rear outer surface of the housing 1, so that it is convenient to add water to the water tank 3 without opening the cover plate 2; and the rice in the receiving tray 8 will not be contaminated when adding water. The nozzle 5 is arranged on the outer side of the receiving tray 8, and the heating plate 9 is arranged below the receiving tray 8. There are air holes on the bottom surface of the receiving tray 8, so that when the water vapor evaporated by the heating plate 9 flows upward, it can quickly contact the rice in the receiving tray 8 through the air holes, thereby adjusting the humidity of the rice.

[0029] In this embodiment, the conveying mechanism 7 includes four main shafts 71, on which spiral blades 72 or breaking rods 73 are provided, wherein the spiral blades 72 are used to push the rice to one side, and the breaking rods 73 are used to disperse the rice to prevent the rice from clumping or agglomerating. In this embodiment, only spiral blades are provided on the two main shafts located at the bottom, which are only used for conveying; both spiral blades 72 and breaking rods 73 are provided on the two main shafts located at the top, so that the rice can be broken while being conveyed. The main shaft is connected to the motor, and the motor is connected to the main control board and works under the control of the main control board. Other relevant functional components and connection relationships in this embodiment can adopt the existing technology, which will not be described in detail here.

[0030] The method of using the rice beater in this embodiment is the same as that of the existing rice beater, except that: the rice beater in this embodiment has a moisturizing function, and can use the humidity sensor 6 to detect the humidity in the receiving tray 8 in real time. When the humidity sensor 6 detects that the humidity inside the receiving tray 8 is lower than the set value, it sends a signal to the main control board, and the main control board controls the water pump to start working, and sends the water in the water tank 3 to the nozzle 5 and sprays it onto the heating plate 9. When the heating plate 9 works, it heats and evaporates the water into water vapor, and the water vapor contacts the rice in the receiving tray 8, so that the humidity of the rice is increased; similarly, when the humidity sensor 6 detects that the humidity inside the receiving tray 8 reaches the set range, it sends a signal to the main control board, and the main control board controls the water pump to stop working, and the heating plate 9 no longer produces water vapor, so as to maintain the current humidity. After a certain period of heat preservation, the humidity sensor 6 detects that the humidity is lower than the set value, and then the humidification function is started again. The specific humidity range of the rice can be customized according to the capacity of the rice beater and the needs of customers.

[0031] In some other specific embodiments, the heating plate 9 can also be directly used as a heat preservation mechanism, thereby omitting a special heat preservation component, making the structure of the entire rice cooker more concise. That is, during its use, when humidification is not required, the nozzle 5 does not spray water, but the heating plate 9 continues to work. At this time, the heating plate 9 only realizes the heat preservation function. When the humidity needs to be increased, the nozzle 5 sprays water, and the heating plate 9 heats the water to evaporate and generate water vapor to humidify the rice.

[0032] The above are only some embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have combinations and modifications of the aforementioned technical features. Without departing from the spirit and scope of the present invention, those skilled in the art may improve, modify, or replace the present invention with equivalents, or apply the structure or method of the present invention to other fields to achieve the same effect, which all fall within the scope of protection of the present invention.
