Abstract
Description
Technical Field
[0001] This utility model relates to dishwashers, and more specifically, to a dishwasher exhaust assembly with a condensation device, and also to a dishwasher having the exhaust assembly. Background Technology
[0002] Modern dishwashers typically include a hot air system and an exhaust system. The hot air system introduces hot air into the dishwasher, while the exhaust system removes internal air, ensuring air balance and ventilation. However, due to the high temperature and humidity inside the dishwasher, the hot, humid air condenses near the exhaust vent, causing undesirable effects.
[0003] Therefore, a new solution is needed to address this problem. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a dishwasher exhaust assembly with a condensation device and a dishwasher.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A dishwasher exhaust assembly with a condenser includes an exhaust device body, an exhaust channel within the exhaust device body, an inlet and an outlet at both ends of the exhaust channel, the inlet communicating with the inner tub of the dishwasher, and the outlet for exhausting gas outwards; it also includes a condenser, which is disposed within the exhaust channel and is used for heat exchange with the gas discharged from the exhaust channel.
[0007] The present invention is further configured such that the condensation device includes a plurality of condensation fins.
[0008] The present invention is further configured such that the condensing fins are arranged in parallel to each other, and a condensing gap is formed between adjacent condensing fins, the condensing gap being open along the direction of the air inlet and the air outlet.
[0009] The present invention is further configured such that the condensation device is a metal condensation coil.
[0010] The present invention is further configured such that the exhaust channel is inclined forward from the air outlet to the air inlet; the air inlet is recessed downward and the air outlet is recessed upward.
[0011] The present invention is further configured such that a baffle plate 1 and a baffle plate 2 are provided in the exhaust channel, and the baffle plate 1 and the baffle plate 2 are respectively located on both sides of the condensation device; gaps are formed between the baffle plate 1 and the baffle plate 2 and the inner walls of both sides of the exhaust channel; the baffle plate 1 and the baffle plate 2 are both arc-shaped structures, and the concave surface is arranged facing the air intake.
[0012] The present invention is further configured such that an odor sensor and a humidity sensor are provided in the exhaust channel.
[0013] The present invention is further configured such that the exhaust device body includes a bottom shell and a cover shell, the bottom shell and the cover shell are sealed together, forming a hollow exhaust channel between the bottom shell and the cover shell; the cover shell is provided with an air outlet at the position corresponding to the air outlet, the bottom shell is provided with an air outlet at the position corresponding to the air inlet, and the air outlet is connected to the inner tub of the dishwasher.
[0014] The present invention is further configured such that the bottom shell is integrally formed with the outer wall of the inner liner, and the air inlet is located on the outer wall of the inner liner.
[0015] This utility model also provides a dishwasher, including the dishwasher exhaust assembly as described above. The dishwasher exhaust assembly has a condensing device, which can condense the air flowing through the exhaust channel, condense the moisture in the gas discharged from the dishwasher, thereby reducing the humidity of the discharged gas and realizing the centralized collection of condensate, which can be returned to the dishwasher.
[0016] In summary, this utility model has the following beneficial effects:
[0017] The temperature inside the dishwasher's inner tub is relatively high, while the temperature of the condenser is relatively low. As the air inside the inner tub is discharged from the exhaust channel, the high-temperature and high-humidity air comes into contact with the low-temperature condenser. The temperature of the high-temperature and high-humidity air decreases, and the moisture in the discharged air is condensed and precipitated. This reduces the humidity of the air discharged from the exhaust channel, preventing the high temperature and high humidity from affecting the external environment and reducing the adverse effects of condensation at the dishwasher's exhaust port.
[0018] The air intake section of the exhaust device body has an air inlet that is connected to the inside of the dishwasher's inner tub. This allows for air circulation and exhaust from the inner tub, while also allowing the air inlet to discharge the condensate collected at the air intake section, so that the condensate can flow back into the dishwasher's inner tub.

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] This embodiment discloses a dishwasher exhaust assembly with a condenser, referring to... Figures 1-4 As shown, the device includes an exhaust device body 2, which contains an exhaust channel 21. The exhaust channel 21 has an inlet 22 and an outlet 23 at its two ends. The inlet 22 communicates with the inner tub 1 of the dishwasher, and the outlet 23 is used to exhaust gas outwards, connecting it to the external environment. Within the exhaust device body 2, the gas to be exhausted can draw gas from the inner tub 1 of the dishwasher into the exhaust device body 2 through the inlet 22, and then be discharged along the exhaust channel 21 to the outlet 23, thereby achieving the discharge of gas from the inner tub 1 of the dishwasher.
[0026] Reference Figure 3 , Figure 4 As shown, a condenser 24 is also installed inside the exhaust device body 2. The condenser 24 is located in the exhaust channel 21, roughly in the middle section of the exhaust channel 21, and can exchange heat with the gas discharged from the exhaust channel 21. The condenser 24 is made of metal and has good thermal conductivity and heat dissipation.
[0027] During the washing process, the temperature inside the inner drum 1 of the dishwasher is relatively high, while the temperature of the condenser 24 is relatively low. As the air inside the inner drum 1 is discharged outward from the exhaust channel 21, the high-temperature and high-humidity air comes into contact with the low-temperature condenser 24. The temperature of the high-temperature and high-humidity air decreases, and the moisture in the discharged air will be condensed and precipitated. This reduces the humidity of the air discharged outward from the exhaust channel 21, thus avoiding the impact of high temperature and high humidity on the external environment.
[0028] The high-temperature and high-humidity gas discharged from the inner tank 1 can have its moisture condensed and collected in the exhaust device body 2, thus achieving condensate collection. In the exhaust gap of the exhaust device body 2, the condenser 24 can exchange heat with the air, and the temperature gradually decreases to a state close to room temperature. Therefore, the exhaust gas can be condensed during the next exhaust process of the dishwasher.
[0029] Specifically, the condenser 24 is made of a metal material with good thermal conductivity. The condenser 24 includes several condenser fins 241, which increase the heat dissipation area of the condenser 24, facilitating heat dissipation and heat exchange. Furthermore, the condenser fins 241 are arranged parallel to each other, and condenser gaps 242 are formed between adjacent condenser fins 241. These condenser gaps 242 are open along the direction of the air inlet 22 and the air outlet 23. During the exhaust process, the condenser fins 241 and the condenser gaps 242 guide the gas discharged from the exhaust channel 21, ensuring effective heat exchange with the discharged gas.
[0030] The condensing device 24 can also be a metal condensing coil, or other types of condensing devices 24, as long as they have a large heat-conducting surface on the outside.
[0031] The exhaust channel 21 is inclined forward from the air outlet 23 toward the air inlet 22. The exhaust channel 21 is generally inclined, and the condensate in the exhaust channel 21 can flow down along the exhaust channel 21, so that the condensate can be generally concentrated near the air inlet 22 of the exhaust channel 21.
[0032] The air intake 22 is recessed downwards and has an air inlet 221 that communicates with the interior of the dishwasher's inner tub 1. This allows for airflow and discharge from the inner tub 1, and also allows condensate collected at the air intake 22 to flow back into the dishwasher's inner tub 1. Conversely, the air outlet 23 is recessed upwards, extending the flow length of the exhaust channel 21 and thus improving the condensation and heat exchange effect of the air within the exhaust channel 21.
[0033] Furthermore, a first baffle 25 and a second baffle 26 are provided in the exhaust channel 21, with the first baffle 25 and the second baffle 26 located on both sides of the condenser 24, respectively. The first baffle 25 and the second baffle 26 can form a more tortuous flow channel in the exhaust channel 21, thereby improving the heat exchange effect of the exhaust gas.
[0034] Specifically, gaps are formed between the first baffle 25, the second baffle 26 and the inner walls on both sides of the exhaust channel 21. The first baffle 25 and the second baffle 26 are both arc-shaped structures, and their concave surfaces are arranged towards the air intake 22.
[0035] Furthermore, the exhaust device body 2 is also equipped with an odor sensor 27 and a humidity sensor 28. The detection ends of the odor sensor 27 and the humidity sensor 28 can extend into the exhaust channel 21, thereby detecting the air parameters in the exhaust channel 21, which facilitates the detection of the air conditions inside the dishwasher. The dishwasher can control the exhaust and ventilation of the dishwasher based on the detection data of the odor sensor 27 and the humidity sensor 28.
[0036] Reference Figure 2 As shown, the exhaust device body 2 includes a bottom shell 201 and a cover shell 202, which are sealed together. A sealing element is installed at the connection between the two to maintain a good sealing state. A hollow exhaust channel 21 is formed between the bottom shell 201 and the cover shell 202. An exhaust port 231 is provided on the cover shell 202 at the position corresponding to the exhaust port 23, and on the bottom shell 201 at the position corresponding to the intake port 22. The exhaust port 23 has a large opening, which can communicate with the external environment and facilitate exhaust. The exhaust port 231 is connected to the inner tub 1 of the dishwasher, and the exhaust port 231 is provided with a number of densely packed small holes, which can prevent large impurities from entering the exhaust channel 21 from the exhaust port 231.
[0037] In this embodiment, the inner tub 1 of the dishwasher and the bottom shell 201 of the exhaust device body 2 are integrally formed, and can be made of plastic material and integrally injection molded. The bottom shell 201 is integrally formed with the outer wall of the inner tub 1, and the bottom of the bottom shell 201 is shared with the outer wall of the inner tub 1. The air inlet 221 of the exhaust device body 2 is located on the outer wall of the inner tub 1, which enables the exhaust channel 21 to communicate with the inner tub 1.
[0038] This embodiment also discloses a dishwasher, including the dishwasher exhaust assembly as described above. The dishwasher exhaust assembly has a condensing device 24, which can condense the air flowing through the exhaust channel 21, condense the moisture in the gas discharged from the dishwasher, thereby reducing the humidity of the discharged gas and realizing the centralized collection of condensate, which can be returned to the dishwasher.
[0039] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
