Description

Technical Field

[0001] This utility model relates to dishwashers, and more specifically, to a dishwasher with an internal air circulation system. Background Technology

[0002] Modern dishwashers typically have air intake and exhaust components, which allow airflow within the dishwasher's interior. A PTC heater inside the air intake component heats the circulating air, creating hot air for drying the dishwasher's interior. The exhaust component removes air from the dishwasher's interior, helping to balance the air pressure. During washing and drying, air from the dishwasher's inner tub is expelled through the exhaust vents. This air contains heat, and its expulsion not only results in heat loss but also causes condensation at the vents. This condensation can drip onto the outside of the dishwasher, causing moisture damage to the cabinetry and furniture.

[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 with an internal air circulation system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The air inlet assembly and the air outlet assembly are respectively installed on the outside of the cabinet. The air inlet assembly communicates with the inner cavity of the cabinet and is used to supply air into the cabinet. The air inlet assembly is provided with an air inlet.

[0007] The air outlet component is connected to the inner cavity of the housing and is used to vent air out of the housing. The air outlet component is provided with an air outlet.

[0008] The circulation pipe includes a first end and a second end, the first end being connected to the air inlet of the air inlet assembly, and the second end being connected to the air outlet of the air outlet assembly.

[0009] The present invention is further configured such that the air inlet component and the air outlet component are located on opposite sides of the housing.

[0010] The present invention is further configured such that both the air inlet assembly and the air outlet assembly are equipped with fans. The fan in the air inlet assembly is used to send air from the air inlet to the inner cavity of the housing; the fan in the air outlet assembly is used to send air from the inner cavity of the housing to the air outlet.

[0011] The present invention is further configured such that a heating device is provided inside the air inlet assembly.

[0012] The present invention is further configured such that the first end and the second end of the circulation pipe are set at the same height.

[0013] The present invention is further configured such that a drainage pipe is connected to the lower part of the middle section of the circulation pipe, and the lower end of the drainage pipe is connected to the inner cavity of the box.

[0014] The present invention is further configured such that the inner cavity of the circulation pipe and the drainage pipe are interconnected, and a flow guiding transition section is formed at the connection.

[0015] The present invention is further provided that a condensation device is provided inside the circulation pipe.

[0025] 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.

[0026] This embodiment discloses a dishwasher with an internal air circulation system, referencing... Figures 1-4 As shown, it includes a housing 1, an air inlet assembly 2, an air outlet assembly 3, and a circulation duct 4.

[0027] Reference Figure 1 , Figure 2 As shown, the air inlet assembly 2 and the air outlet assembly 3 are respectively installed on the outside of the housing 1. The air inlet assembly 2 is connected to the inner cavity of the housing 1 and is used to supply air into the housing 1. An air guide port is provided on the outer wall of the housing 1, and the air inlet assembly 2 is connected to the air guide port. The air inlet assembly 2 is provided with an air inlet 21.

[0028] A fan is installed inside the air inlet assembly 2, which can deliver air from the air inlet 21 to the inner cavity of the housing 1. In addition, a heating device is provided inside the air inlet assembly 2. The heating device is a PTC heater, which can heat the air flowing through it, thereby generating hot air; hot air can be delivered into the inner cavity of the housing 1 through the air inlet assembly 2.

[0029] Reference Figure 3 As shown, the air outlet assembly 3 is connected to the inner cavity of the housing 1, and is used to expel air from the housing 1 to the outside, thereby achieving balanced airflow within the housing 1. An air guide port is provided on the outer wall of the housing 1, and the air outlet assembly 3 is connected to this air guide port, with an air outlet 31 provided on the air outlet assembly 3. A fan is installed inside the air outlet assembly 3, which can deliver air from the inner cavity of the housing 1 towards the air outlet 31, thereby expelling the air from the inner cavity of the housing 1.

[0030] The circulation pipe 4 includes a first end 41 and a second end 42. The first end 41 is connected to the air inlet 21 of the air inlet assembly 2, and the second end 42 is connected to the air outlet 31 of the air outlet assembly 3. The circulation pipe 4 enables airflow, allowing air inside the dishwasher to be discharged from the air outlet assembly 3, flow through the circulation pipe 4, and then return to the inner cavity of the cabinet 1 from the air inlet assembly 2. This achieves internal air circulation within the dishwasher, thus enabling air circulation while preventing heat loss after air is discharged.

[0031] A drain pipe section 43 is connected to the lower middle section of the circulation pipe 4, and the lower end of the drain pipe section 43 is connected to the inner cavity of the housing 1. The circulation pipe 4 and the drain pipe section 43 form a T-shaped structure. The drain pipe section 43 extends downward, which can realize the downward return of condensate, and can return the condensate in the circulation pipe 4 back to the inner cavity of the housing 1, eliminating the condensate discharged outward.

[0032] In addition, a condenser 6 is installed inside the circulation pipe 4. The condenser 6 is made of metal and has good thermal conductivity. The condenser 6 can adopt a finned structure or a coiled structure, and has a large heat conduction area.

[0033] During the washing process, the temperature inside the dishwasher cabinet 1 is relatively high, while the temperature of the condenser 6 is relatively low. The air inside the cabinet 1 is discharged outward from the air outlet assembly 3 and flows through the circulation pipe 4. The high temperature and high humidity air comes into contact with the low temperature condenser 6, and the temperature of the high temperature and high humidity air decreases. The moisture in the air will be condensed and precipitated, thereby reducing the humidity of the air in the circulation pipe 4, and the condensate can be condensed in the circulation pipe 4.

[0034] The air inside cabinet 1 will circulate for a period of time and then stop. During the interval between circulations, the condenser 6 can exchange heat with the air again, and the temperature will gradually drop to near room temperature. This allows the condensation of the exhaust gas to be achieved during the next exhaust process of the dishwasher.

[0035] Reference Figure 1 , Figure 2 As shown, the air inlet assembly 2 and the air outlet assembly 3 are located on opposite sides of the housing 1. The air inlet 21 of the air inlet assembly 2 and the air outlet 31 of the air outlet assembly 3 are approximately at the same height. The first end 41 and the second end 42 of the circulation pipe 4 are set at the same height, which enables the air inlet assembly 2 and the air outlet assembly 3 to be interconnected and achieve air circulation.

[0036] The circulation pipe 4 and the drainage pipe section 43 form a T-shaped structure, with the drainage pipe section 43 connected to the lower middle section of the circulation pipe 4. The inner cavities of the circulation pipe 4 and the drainage pipe section 43 are interconnected, forming a T-junction. Furthermore, a flow guiding transition section 46 is formed at the connection point, which can guide the flow at an angle towards the drainage pipe section 43.

[0037] The condenser is located above the upper port of the drain pipe section 43, which allows condensation to form above the connection port of the drain pipe section 43, enabling the condensate to quickly enter the drain pipe section 43 and achieve rapid condensate return.

[0038] Reference Figure 2 , Figure 4 As shown, a condensate inlet 44 is provided at the lowest point of the drain pipe section 43, and the lower end of the drain pipe section 43 forms a constricted structure to allow condensate to collect. A condensate inlet 5 is provided on the side wall of the tank body 1, and the condensate inlet 44 and the condensate inlet 5 are connected to each other, thereby enabling the reflux of condensate into the inner cavity of the tank body 1.

[0039] Odor and humidity sensors are installed inside the air outlet assembly 3. The corresponding sensors can be used to check the air parameters during circulation.

[0040] 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.
