Description

Technical Field

[0001] This utility model relates to the technical field of kitchenware, and in particular to an energy-saving noodle cooker. Background Technology

[0002] During use, as the number of batches cooked increases, the water in the cooking tank of a noodle cooker becomes increasingly cloudy. To ensure the taste and safety of the cooked food, it is necessary to periodically drain some of the water and replenish it with fresh water to keep the water clean. To reduce energy consumption, existing noodle cookers use a system where the inlet pipe is wrapped around the outside of the drain pipe in the cooking tank. Hot water drained from the cooking tank preheats the cold water in the inlet pipe, thus reducing the power consumption of the heating device. However, because the hot water flows through the drain pipe for a short time, the heat exchange time between the cold water in the inlet pipe and the hot water in the drain pipe is also short. This results in poor preheating efficiency of the inlet water using this waste heat recovery method, limiting the energy-saving effect of the heating device. Utility Model Content

[0003] The purpose of this utility model is to provide an energy-saving noodle cooker, which has the advantages of simple structure, reasonable design, good water preheating effect, and good energy saving effect of heating device.

[0005] The working principle of this utility model is as follows:

[0006] During use, the water injection mechanism fills the cooking tank with water, and the heating device heats the water in the cooking tank for cooking. When the water in the cooking tank needs to be replaced, the water injection mechanism fills the cooking tank, causing the hot water to overflow the overflow baffle and enter the overflow tank. The hot water stored in the overflow tank continuously heats the cold water in the preheating section, thereby increasing the initial temperature of the water injected into the cooking tank and reducing the operating temperature of the heating device. By temporarily storing the overflowing hot water in the overflow tank, the heat exchange time between the hot water to be discharged and the cold water in the preheating section is extended, thereby improving the water preheating effect of the noodle cooker and improving the energy efficiency of the heating device. In addition, when the overflow tank stores the hot water that overflowed during the previous water injection, it can preheat the water in the preheating section before filling the water injection section, further improving the water preheating effect of the noodle cooker and making the noodle cooker more energy-efficient during long-term operation.

[0007] Furthermore, in the energy-saving noodle cooker described above, the preheating part is a water tank.

Detailed Implementation

[0029] Example 1

[0030] like Figures 1 to 7An energy-saving noodle cooker according to Embodiment 1 includes a cooker body 1, two heating devices 2, two water injection mechanisms 4, two bubbling racks 3, and a control module 9. The cooker body 1 includes a base 11 and a cooktop 12, with the cooktop 12 mounted on the base 11. A water storage tank 121 with an upper opening is formed on the cooktop 12. The water storage tank 121 is divided into two cooking tanks 122 and one overflow tank 123 by two overflow baffles 125. The top edge of the overflow baffles 125 is lower than the opening of the water storage tank 121. The two cooking tanks 122 are not directly connected. The cooking trough 122 corresponds to an overflow baffle 125. The cooking trough 122 is connected to the overflow trough 123 through the gap between the top edge of the overflow baffle 125 and the opening of the water storage trough 121. A cleaning drain is formed at the bottom of the cooking trough 122. The cleaning drain is connected to a drain valve 20 through a drain pipe 40. The drain valve 20 is connected to an external drain pipe. The overflow trough 123 is provided with an overflow drain 1242. The height of the overflow drain 1242 is between the bottom of the overflow trough 123 and the top edge of the overflow baffle 125. The overflow drain 1242 and the overflow baffle 125 are connected to the overflow trough 123. An external drain pipe is connected; the heating device 2 is an electric heating element, and two heating devices 2 are respectively installed in the cooking tank 122. The heating device 2 is used to heat the fluid in the cooking tank 122; two bubble racks 3 are installed on the bottom of the two cooking tanks 122, and the bubble racks 3 are located above the heating end of the heating device 2. The bubble racks 3 are used to generate bubbles after the water in the cooking tank 122 is heated to boiling, so as to drive the food in the cooking tank 122 to roll, thereby heating more evenly and cooking faster; the water injection mechanism 4 includes a preheating part 41 and a water injection part 42. The preheating section 41 of each of the two water injection mechanisms 4 is connected to the external tap water through a diversion solenoid valve 10. The preheating section 41 of each water injection mechanism 4 is configured to exchange heat with the fluid in the overflow tank 123. The water injection section 42 of each water injection mechanism 4 is connected to its preheating section 41. The water injection sections 42 of the two water injection mechanisms 4 are correspondingly arranged with the two cooking tanks 122. The water injection section 42 is a pipe and is used to inject water into the cooking tanks 122. The control module 9 is electrically connected to the heating device 2 and controls the operation of the heating device 2.

[0031] The working principle of this embodiment is as follows:

[0032] During use, the water injection mechanism 4 fills the cooking tank 122 with water, and the heating device 2 heats the water in the cooking tank 122 for cooking. When it is necessary to replace the water in the cooking tank 122, the water injection mechanism 4 injects water into the cooking tank 122, causing the hot water in the cooking tank 122 to overflow the overflow baffle 125 and enter the overflow tank 123. Since the height of the overflow drain 1242 is between the bottom of the overflow tank 123 and the top edge of the overflow baffle 125, the hot water stored in the overflow tank 123 maintains the rated water level. The hot water stored in the overflow tank 123 can continuously heat the cold water in the preheating section 41, thereby increasing the initial temperature of the water injected into the cooking tank 122 and reducing the function of the heating device 2. By temporarily storing the hot water overflowing from the cooking tank 122 in the overflow tank 123, the heat exchange time between the hot water to be discharged and the cold water in the preheating section 41 is extended, thereby improving the water preheating effect of the noodle cooker and making the heating device 2 more energy-efficient. In addition, when the overflow tank 123 stores the hot water that overflowed during the last water filling, the water in the preheating section 41 can be preheated before water filling the water filling section 42, further improving the water preheating effect of the noodle cooker and making the noodle cooker more energy-efficient when working for a long time.

[0033] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the preheating section 41 is a water tank. The preheating section 41 is set on the furnace platform 12 and is located on the outside of the overflow trough 123, close to the wall of the overflow trough 123. The inner cavity of the preheating section 41 and the inner space of the overflow trough 123 are separated by one and only one heat exchange partition plate 1231. The preheating section 41 has an inlet 411 and an outlet 412 that communicate with the inner cavity. The inlet 411 is located at the lower part of the preheating section 41 and is connected to the diversion solenoid valve 10 through the water inlet pipe 30. The outlet 412 is located at the upper part of the preheating section 41 and is connected to the water injection section 42. The design of separating the inner cavity of the preheating section 41 from the inner space of the overflow tank 123 by one and only one heat exchange partition plate 1231 reduces the thermal resistance between the cold water in the preheating section 41 and the hot water in the overflow tank 123, resulting in higher heat exchange efficiency and improving the water preheating effect of this noodle cooker. In addition, the preheating section 41 adopts a water tank design, where the pre-injected cold water is stored in the preheating section 41 before the water injection mechanism 4 injects water into the cooking tank 122. This allows the pre-injected cold water to fully exchange heat with the hot water in the overflow tank 123, further improving the water preheating effect of this noodle cooker.

[0034] like Figure 1 , Figure 3 and Figure 4As shown, this embodiment also includes a heat-insulating cover 5, which is disposed above the opening of the overflow tank 123. The heat-insulating cover 5 can prevent the loss of hot air in the overflow tank 123, thereby keeping the hot water in the overflow tank 123 warm and ensuring that the noodle cooker has a good water preheating effect.

[0035] like Figure 3 , Figure 4 and Figure 5 As shown, a drain outlet is formed on the bottom of the overflow tank 123, and the drain outlet is connected to an external drain pipe through an overflow pipe 50. A drain rod 124 is provided on the overflow tank 123, with one end of the drain rod 124 inserted into the drain outlet. A drain channel 1241 connecting its two ends is formed inside the drain rod 124, and the drain channel 1241 is connected to the drain outlet. An overflow drain outlet 1242 is formed on the circumferential surface of the drain rod 124, and the overflow drain outlet 1242 is connected to the drain channel 1241. When the noodle cooker stops working and needs cleaning, the drain rod 124 can be removed from the drain outlet, allowing the water in the overflow tank 123 to be discharged from the drain outlet, making the cleaning of the overflow tank 123 more convenient.

[0036] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, this embodiment also includes six cooking baskets 6 and two partition platforms 7. The two partition platforms 7 are respectively arranged above the openings of the two cooking troughs 122. Each partition platform 7 has a horizontally oriented surface 71 with three cooking openings 72 connected to the openings of the cooking troughs 122. Each cooking basket 6 has several sieve holes 61. The six cooking baskets 6 are hung above the six cooking openings 72, with the bottom of each basket extending through the opening 72 into the corresponding cooking trough 122. During cooking, food is placed in the cooking basket 6, and hot water from the cooking trough 122 flows into the cooking basket 6 through the sieve holes 61 to cook the food. By setting up the cooking baskets 6, the separation of food from the hot water in the cooking trough 122 is more convenient, improving work efficiency.

[0037] like Figure 3 and Figure 5 As shown, a water injection channel 73 is formed on the partition platform 7. The water injection channel 73 is arranged horizontally, with one end of the water injection section 42 connected and the other end of the water injection channel 73 being a closed structure. Three water injection holes 731 are formed on the inner wall of the water injection channel 73 along its length, and the water injection holes 731 are oriented towards the opening of the corresponding cooking tank 122. With this design, the cold water flowing out of the water injection section 42 is diverted into the cooking tank 122 through the water injection channel 73, making the temperature distribution of the water in the cooking tank 122 more uniform and improving the heating efficiency of the heating device 2.

[0038] like Figure 3 and Figure 6 As shown, the water injection channel 73 is located beside the countertop 71. Two overflow holes 732 are formed on the inner wall of the water injection channel 73. The overflow holes 732 are higher than the water injection holes 731 and the countertop 71, and are oriented towards the countertop 71. When the water level in the water injection channel 73 is too high, cold water in the water injection channel 73 enters the countertop 71 through the overflow holes 732 and flows into the cooking tank 122 through the cooking opening 72. This design avoids excessive load on the supporting structure of the stove body 1 due to excessive load on the partition table 7, thus improving its service life.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, this embodiment also includes six lifting mechanisms 8, each comprising a hanging bracket 81, a lifting push rod 82, and a drive assembly 83. The lifting push rod 82 is movably mounted on the furnace body 1. The hanging bracket 81 is mounted on the lifting push rod 82 and positioned above the cooking opening 72 of the partition platform 7. The six cooking baskets 6 are respectively hung on the hanging brackets 81 of the six lifting mechanisms 8. The drive assembly 83 is mounted on the furnace body 1 and is used to drive the lifting push rod 82 to perform lifting and lowering actions, allowing the cooking baskets 6 to be moved up and down by the hanging brackets 81. The control module 9 is electrically connected to the drive assembly 83 and is used to control the operation of the drive assembly 83. With this design, after the cooking time of the cooking baskets 6 reaches the preset time, the control module 9 can lift the cooking baskets 6 through the lifting mechanism 8 to separate them from the hot water in the cooking tank 122, avoiding excessive heating time that could affect the taste of the food, resulting in a high degree of automation.

[0040] like Figure 7As shown, the drive assembly 83 includes a first mounting base 831, a second mounting base 832, a sliding seat 833, two guide rods 834, a lifting member 835, and a drive motor 836. The first mounting base 831 and the second mounting base 832 are mounted vertically on the furnace body 1. One end of each of the two guide rods 834 is connected to the first mounting base 831, and the other end of each guide rod 834 is connected to the second mounting base 832. The length of the two guide rods 834 is vertical. The sliding seat 833 is located between the first mounting base 831 and the second mounting base 832, and the sliding seat 833 and the two guide rods 834 can slide vertically. The lifting push rod 82 is slidably mounted on the first mounting base 831, and the hanging bracket 81 is mounted on the part of the lifting push rod 82 that is higher than the first mounting base 831. The bottom end of the lifting push rod 82 is connected to the sliding base 833. The lifting member 835 is slidably mounted on the second mounting base 832, and the top end of the lifting member 835 is connected to the sliding base 833. The drive motor 836 is mounted on the second mounting base 832 and is electrically connected to the control module 9. The drive motor 836 is used to drive the lifting member 835 to slide up and down, so that the hanging bracket 81 can be driven to lift and lower. Through this design, the lifting push rod 82 can lift and lower more smoothly, improving the stability of the cooking basket 6 and preventing hot water from splashing out of the cooking tank 122 due to the movement of the cooking basket 6, thus improving safety.

[0041] Example 2

[0042] like Figure 8 This is an energy-saving noodle cooker according to Embodiment 2. The difference between Embodiment 2 and Embodiment 1 is that the preheating section 41 is a pipe. The preheating section 41 is laid on the stove platform 12 and is located close to the wall of the overflow trough 123 on the outside of the overflow trough 123. The inner cavity of the preheating section 41 and the inner space of the overflow trough 123 are separated by one and only one heat exchange partition plate 1231. Compared with Embodiment 1, the preheating section 41 in this embodiment adopts a pipe structure, which makes the flow direction of the newly injected cold water more stable, reduces the heat exchange between the newly injected cold water and the preheated cold water, and allows the preheated cold water to maintain a higher temperature, improving the water preheating effect of the noodle cooker.

[0043] Example 3
