Technical Field
[0001] This application relates to the field of dishwashers, and more particularly to a commercial gas-fired automatic lifting dishwasher. Background Technology
[0002] Commercial dishwashers are devices that automatically clean tableware such as bowls, chopsticks, plates, dishes, knives, and forks. Commercial dishwashers can be categorized into lift-up dishwashers, tunnel dishwashers, and chain dishwashers. They are suitable for large, medium, and small restaurants, hotels, canteens in government agencies and schools, factories and mines, central kitchens, etc., and are now widely used. Currently, commercial dishwashers on the market generally include a lid, a dish rack, a washing sink, and a heating module. The washing sink is installed below the dish rack, and the lid is installed on top of the dish rack, covering it. An upper main washing arm is installed at the bottom of the lid. A lower rinsing arm and a lower main washing arm are installed inside the washing sink. The heating module is installed on the dish rack, which is equipped with a spray pump and a washing pump. The spray pump draws water heated by the heating module to the lower rinsing arm to spray and heat the dishes to remove grease. The washing pump then draws water to the upper and lower main washing arms to clean the dishes.
[0003] Currently, commercial dishwashers typically use electric heating modules to heat water.
[0004] Regarding the aforementioned technologies, the use of electric heating modules typically requires high power consumption. Many older houses do not have electrical networks designed for dishwashers, which can lead to insufficient electrical capacity, making it difficult to drive high-power dishwashers.

[0030] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.
[0031] This application discloses a commercial gas-fired automatic lifting dishwasher. (Refer to...) Figure 1 and Figure 2 A commercial gas-fired automatic lifting dishwasher includes a cabinet 1, a cleaning mechanism 2, a gas heating module 3, and a lifting mechanism 4, all of which are located inside the cabinet 1.
[0032] Reference Figure 2 and Figure 3 The housing 1 is divided into a placement layer 11, a cleaning layer 12, and an installation layer 13. The placement layer 11, the cleaning layer 12, and the installation layer 13 are distributed from top to bottom along the height direction of the housing 1. The cleaning mechanism 2 is set in the placement layer 11 and the cleaning layer 12. The gas heating module 3 is installed in the installation layer 13 of the housing 1 and is used to heat the water. The lifting mechanism 4 is set at the top of the housing 1.
[0033] Reference Figure 4 The placement layer 11 is equipped with a placement rack 111, the cleaning layer 12 is equipped with a cleaning water tank 121, the housing 1 is equipped with a main washing pipe 14, one end of the main washing pipe 14 is connected to the outlet of the gas heating module 3, and the other end of the main washing pipe 14 is connected to the cleaning water tank 121. The cleaning water tank 121 is equipped with an overflow pipe 1211, one end of the overflow pipe 1211 is connected to the cleaning water tank, and the other end of the overflow pipe 1211 is connected to the outlet of the housing 1, so that the water level in the cleaning water tank is always within a suitable range. The cleaning water tank 121 is equipped with a heating pipe 1212 for heating the water in the cleaning water tank 121, so that the water temperature in the cleaning water tank 121 is always within the set range.
[0034] Reference Figure 2The placement layer 11 of the box body 1 has a first placement opening 112 and a second placement opening 113 that are respectively opened through both sides. The washed tableware is placed on the placement rack 111 through the first placement opening 112 or the second placement opening 113. A first entry rack 114 and a second entry rack 115 are respectively installed on both sides of the box body 1. The surfaces of the first entry rack 114 and the second entry rack 115 are both horizontal with the surface of the placement rack 111. The first entry rack 114 is set directly opposite the first placement opening 112, and the second entry rack 115 is set directly opposite the second placement opening 113, so that the tableware is placed on the placement rack 111 through the first entry rack 114 or the second entry rack 115.
[0035] Reference Figure 5 The cleaning mechanism 2 includes a main washing assembly 21, which includes a first main washing arm 211, a second main washing arm 212, and a third main washing arm 213. The first main washing arm 211, the second main washing arm 212, and the third main washing arm 213 are all hinged inside the housing 1 and located at the top of the cleaning water tank 121. The first main washing arm 211, the second main washing arm 212, and the third main washing arm 213 are arranged sequentially from top to bottom along the height direction of the housing 1. The first main washing arm 211 is located at the top of the placement layer 11, directly opposite the placement rack 111. The second... The main washing arm 212 and the third main washing arm 213 are located on the washing layer 12 and are directly opposite the bottom of the placement rack 111. The mounting layer 13 of the housing 1 is equipped with a main washing pump 131. The inlet of the main washing pump 131 is connected to the washing pool 121. The first main washing arm 211, the second main washing arm 212 and the third main washing arm 213 are all connected to the outlet of the main washing pump 131. When the main washing assembly 21 performs the main washing of the tableware, it will extract an appropriate amount of detergent and add it to the washing pool 121 to achieve a better cleaning effect on the oil stains of the tableware.
[0036] Reference Figure 5 The cleaning mechanism 2 also includes a rinsing assembly 22, which includes a first rinsing arm 221, a second rinsing arm 222, and a third rinsing arm 223. The first rinsing arm 221, the second rinsing arm 222, and the third rinsing arm 223 are distributed sequentially from top to bottom along the height direction of the housing 1. The first rinsing arm 221 is hinged to the first main washing arm 211, the second rinsing arm 222 is hinged to the second main washing arm 212, and the third rinsing arm 223 is hinged to the third main washing arm 213. A rinsing pump 13 is installed on the mounting layer 13 of the housing 1. 2. The inlet of the rinsing pump 132 is connected to the outlet of the gas heating module 3. The first rinsing arm 221, the second rinsing arm 222 and the third rinsing arm 223 are all connected to the outlet of the rinsing pump 132. When the rinsing component 22 rinses the tableware, it extracts an appropriate amount of rinsing agent and adds it to the rinsing water. Then, it sprays the rinsing component 22 onto the surface of the tableware, thereby breaking up the water droplets and water film on the surface of the tableware, so that the water on the surface of the tableware evaporates and leaves the tableware, thus making the rinsed tableware clean and new.
[0037] Reference Figure 6 The gas heating module 3 has a steam port 31, and the housing 1 is equipped with a steam pipe 15. One end of the steam pipe 15 is connected to the steam port 31, and the other end of the steam pipe 15 is connected to the washing water tank. This allows the steam generated by the gas heating module 3 to preheat the tableware before the washing mechanism 2 washes it, thus raising the temperature of the tableware. This improves the washing effect of the washing mechanism 2 on the tableware and increases the heat energy utilization rate of the gas heating module 3. It also makes the gas heating module 3 more suitable for dishwashers.
[0038] Reference Figure 7 and Figure 8 The lifting mechanism 4 includes a first lifting roller 41, a first closing curtain 42, a second lifting roller 43, a second closing curtain 44, and a driving component. The first lifting roller 41 and the second lifting roller 43 are rotatably mounted on the top of the housing 1. The first closing curtain 42 is wrapped around the first lifting roller 41 and is slidably fitted on the side of the housing 1 facing the first placement opening 112 to close the first placement opening 112. The second closing curtain 44 is wrapped around the second lifting roller 43 and is slidably fitted on both sides of the housing 1 facing the second placement opening 113 to close the second placement opening 113. The driving component (not shown in the figure) is installed on the housing 1 and is used to drive the first lifting roller 41 and the second lifting roller 43.
[0039] The implementation principle of a commercial gas-fired automatic lifting dishwasher according to this application embodiment is as follows: When the dishwasher washes the dishes, gas enters the gas heating module 3 for combustion, and cold water enters the gas heating module 3 from the water inlet of the cabinet 1 for heating. When the cold water is heated to a suitable main wash temperature by the gas heating module 3, the water used for the main wash of the dishes flows into the cleaning water tank 121 along the main wash pipe 14, thereby raising the water level in the cleaning water tank 121 until the water level in the cleaning water tank 121 is raised to a suitable height. Then, the main wash pump 131 works to lift the cleaning water tank 121. Water is drawn in and delivered to the main washing assembly 21, causing water from the cleaning pump to spray out from the first main washing arm 211, the second main washing arm 212, and the third main washing arm 213, performing a main wash to remove oil and dirt from the dishes. Simultaneously, the water sprayed from the first main washing arm 211, the second main washing arm 212, and the third main washing arm 213 rinses the dishes and then flows back to the washing water tank 121 for repeated use, saving water resources. After the dishes have completed the main wash, the rinsing pump 132 operates, drawing water heated to a suitable temperature from the gas heating module 3 for rinsing. Warm water is pumped to the rinsing assembly 22, causing the rinsing water to spray out from the first rinsing arm 221, the second rinsing arm 222, and the third rinsing arm 223 to rinse and clean the tableware, thereby achieving the effect of high-temperature disinfection of the tableware and completing the cleaning of the tableware. Then, the lifting mechanism 4 is driven, making it convenient for staff to take out the cleaned tableware. The water used to rinse the tableware is added to the washing water tank 121 for use in the main washing of tableware. When the water level in the washing water tank 121 is higher than the appropriate range, the excess water overflows from the overflow pipe 1211, thereby ensuring that the water level in the washing water tank 121 is always within the appropriate range. This improves the problem that electric heating modules usually require high power consumption. Many old houses do not consider the use of dishwashers in their electrical networks, which can easily lead to insufficient capacitors in old houses, making it difficult to drive high-power dishwashers. This reduces the number of dishwasher users and leads to poor dishwasher adoption. In addition, the use of gas makes dishwashers more economical and reduces the complexity of dishwasher control programs, making dishwasher circuits simpler and more replaceable.
[0040] In addition, the overall operation and control of the dishwasher has reduced the involvement of the control program, thereby reducing the dishwasher's demand for the control program, further reducing the dishwasher's power consumption, further reducing the demand for the electrical network, and thus further expanding the user base of the dishwasher.
[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
