Abstract
Description
Technical Field
[0001] This utility model relates to cleaning equipment, and more specifically, to a dishwasher. Background Technology
[0002] After washing, dishwashers require sterilization and ventilation to ensure a clean internal environment, preventing excessive bacterial growth and odors. Some dishwashers are equipped with ultraviolet (UV) lamps inside the cavity; UV radiation effectively sterilizes and reduces bacteria. Current dishwashers are typically built-in or cabinet-style, resulting in larger interior spaces. The UV sterilization components installed within these dishwashers are also relatively large, taking up space and limiting the arrangement of dish racks and tableware. In smaller dishwashers, where space is already limited, installing standard UV sterilization modules would further impact space, with the impact being even greater on smaller models.
[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.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A dishwasher includes a cabinet, an ultraviolet sterilization component, an exhaust component, and an air intake component. The ultraviolet sterilization component is installed on the top of the cabinet, and the exhaust component and the air intake component are respectively installed on both sides of the cabinet.
[0007] The top of the box has an installation port. The ultraviolet sterilization component includes an installation cylinder, a sealing ring and a connecting sleeve. An ultraviolet light-emitting element is installed inside the installation cylinder. The lower end of the installation cylinder is closed by a light-transmitting end cap and extends into the box from the installation port.
[0008] The mounting cylinder and the mounting port are sealed by a sealing ring. A limiting protrusion ring is fixedly connected to the lower outer circumference of the mounting cylinder. The connecting sleeve is located at the upper part of the box and is threadedly connected to the upper outer circumference of the mounting cylinder. The mounting cylinder and the limiting protrusion ring are used to limit the position on the upper and lower sides of the mounting port.
[0009] The present invention is further configured such that an upper side and a lower side are formed on the upper and lower sides of the mounting port, respectively, and the sealing ring is sleeved on the outside of the mounting cylinder, and the sealing ring abuts against and seals against the lower side of the mounting port and the limiting protrusion ring.
[0010] The present invention is further configured such that the outer circumference of the mounting cylinder is provided with an external thread, the inner circumference of the connecting sleeve is provided with an internal thread, and the connecting sleeve is fitted outside the mounting cylinder to achieve a threaded connection.
[0011] The present invention is further configured such that a plurality of protrusions are fixedly connected to the outer periphery of the connecting sleeve, and the protrusions abut and limit each other with the upper side of the mounting port.
[0012] The present invention is further provided that the circumferential surface of the mounting cylinder is provided with a through hole that extends through both the inside and outside. The through hole is located on the upper side of the box body and is used to connect the inner cavity of the mounting cylinder with the outer space of the box body.
[0013] The present invention is further configured such that a stepped groove is formed on the lower side of the mounting port, the stepped groove is arranged around the mounting port, and the sealing ring and the limiting protrusion are embedded in the stepped groove.
[0014] The present invention is further configured such that the outer periphery of the limiting protrusion is larger than the mounting opening, and the mounting opening has a circular hole structure.
[0015] The present invention is further configured such that the exhaust component and the air intake component are respectively installed on opposite sides of the housing, the exhaust component is used to exhaust air from the inner cavity of the housing to the outside, and the air intake component is used to supply air from the outside to the inner cavity of the housing; a heater is provided inside the air intake component.
[0016] The present invention is further configured such that the air intake assembly is equipped with a negative ion generator for generating negative ions within the air intake assembly; and the exhaust assembly is equipped with a humidity sensor and an odor sensor for detecting the gas discharged from the inner cavity of the box.
[0017] In summary, this utility model has the following beneficial effects:
[0018] By installing a UV sterilization component inside the dishwasher, the internal cavity can be sterilized with ultraviolet light, thereby killing bacteria inside the drum and ensuring the cleanliness of the tableware. A mounting hole is directly provided on the upper side of the dishwasher body, allowing the housing of the UV sterilization module (i.e., the mounting cylinder) to be installed. The lower end of the mounting cylinder is designed as a closed yet translucent structure, extending into the dishwasher's internal cavity. The remaining parts of the UV sterilization component can be positioned on the upper outer side of the dishwasher body, reducing the space occupied by the UV sterilization component within the cavity. Furthermore, a stepped groove is formed below the mounting opening to accommodate the portion of the UV sterilization component extending into the cavity, creating an embedded recessed structure that further reduces the space occupied by the UV sterilization component within the dishwasher's internal cavity.
[0019] By installing an exhaust assembly and an air intake assembly on both sides of the cabinet, the exhaust assembly exhausts air from the inner cavity of the cabinet to the outside, while the air intake assembly supplies air from the outside into the inner cavity. A negative ion generator produces negative ions through ionization within the air intake assembly, which purify the air inside the dishwasher when introduced into the cavity. Humidity and odor sensors are installed within the exhaust assembly; these sensors detect the parameters of the gas discharged from the inner cavity, thus enabling the monitoring of the air quality within the cavity.
[0020] The UV sterilization component can be installed inside the mounting sleeve by connecting the mounting sleeve with the mounting sleeve. The sealing ring is installed between the lower side of the mounting port and the limiting protrusion ring, and can press against the lower side of the mounting port and the limiting protrusion ring respectively to seal the connection.

[0026] 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.
[0027] This embodiment discloses a dishwasher, with reference to... Figures 1-4As shown, it includes a housing 1, an ultraviolet sterilization component 20, an exhaust component 30, and an air intake component 40. The ultraviolet sterilization component 20 is installed on the top of the housing 1, and can sterilize the inside of the housing 1 by ultraviolet irradiation.
[0028] An exhaust assembly 30 and an intake assembly 40 are respectively installed on both sides of the housing 1. The exhaust assembly 30 and the intake assembly 40 are respectively installed on opposite sides of the housing 1. The exhaust assembly 30 can exhaust air from the inside of the housing 1 to the outside, and the intake assembly 40 can supply air from the outside to the inside of the housing 1. The supply and exhaust of air can achieve pressure balance inside the housing 1.
[0029] A heater is installed inside the air intake assembly 40 to heat the air inside the air intake assembly 40, thereby generating hot air that can be delivered to the cabinet 1. In order to improve the air quality inside the dishwasher, a negative ion generator is installed inside the air intake assembly 40. The negative ion generator can generate negative ions in the air intake assembly 40 through ionization, and when they are sent into the inside of the dishwasher, they can purify the air inside the dishwasher.
[0030] A humidity sensor and an odor sensor are installed inside the exhaust assembly 30. The sensors can detect the parameters of the gas discharged from the inner cavity of the housing 1, thereby enabling the detection of the air in the inner cavity.
[0031] Reference Figure 3 , Figure 4 As shown, an installation port 11 is provided at the top of the housing 1, and the ultraviolet sterilization component 20 is installed at this installation port 11. The ultraviolet sterilization component 20 includes an installation cylinder 2, a sealing ring 3, and a connecting sleeve 4. An ultraviolet light-emitting element is installed inside the installation cylinder 2. The lower end of the installation cylinder 2 is closed by a light-transmitting end cap 22 and extends into the housing 1 through the installation port 11 to achieve installation of the installation cylinder 2. To achieve a seal at the installation port 11, the installation cylinder 2 and the installation port 11 are sealed by the sealing ring 3.
[0032] A limiting protrusion ring 23 is fixedly connected to the lower outer periphery of the mounting cylinder 2. The outer periphery of the limiting protrusion ring 23 is larger than the mounting opening 11, and can form a limiting block on the lower side of the mounting opening 11.
[0033] Reference Figure 4 As shown, the connecting sleeve 4 is located on the upper part of the housing 1 and is threadedly connected to the upper outer circumference of the mounting cylinder 2. The outer circumference of the mounting cylinder 2 is provided with external threads 21, and the inner circumference of the connecting sleeve 4 is provided with internal threads 41. The connecting sleeve 4 is fitted onto the outside of the mounting cylinder 2 to achieve a threaded connection.
[0034] The upper side 112 and the lower side 111 are formed on the upper and lower sides of the mounting port 11, respectively, and the sealing ring 3 is sleeved on the outside of the mounting cylinder 2. The sealing ring 3 is installed between the lower side 111 of the mounting port 11 and the limiting protrusion ring 23, and can press against each other and seal with the lower side 111 of the mounting port 11 and the limiting protrusion ring 23, respectively.
[0035] During installation, the connecting sleeve 4 is fitted over the mounting cylinder 2 and is threadedly connected to the mounting cylinder 2. The connection between the two can be achieved by tightening the threads. The mounting cylinder 2 and the limiting protrusion ring 23 can respectively limit the upper and lower sides of the mounting opening 11, thereby achieving clamping and fixing on the upper and lower sides of the mounting opening 11.
[0036] In addition, to facilitate the screwing operation of the connecting sleeve 4, several protrusions 42 are fixedly connected to the outer periphery of the connecting sleeve 4. The protrusions 42 abut against and limit the upper side 112 of the mounting port 11. On the one hand, the protrusions 42 can improve the grip stability of the connecting sleeve 4 and facilitate screwing. On the other hand, the protrusions 42 can increase the limiting area and can stably abut and limit the upper part of the housing 1.
[0037] Reference Figure 4 As shown, a stepped groove 113 is formed on the lower side 111 of the mounting port 11, and the stepped groove 113 is arranged around the mounting port 11. During installation, the sealing ring 3 and the limiting protrusion ring 23 can be embedded in the stepped groove 113, and there will be no protrusion on the inner wall of the dishwasher body 1, so that the ultraviolet sterilization component 20 will not protrude and occupy space in the inner cavity of the body 1.
[0038] The mounting cylinder 2 has a through hole 24 extending both internally and externally on its circumferential surface, located on the upper side of the housing 1. During installation, the mounting cylinder 2 extends upward from the inside of the housing 1, with the through hole 24 on its outer circumference located on the upper side of the housing 1, and the outer opening of the through hole 24 protruding from the upper side of the housing 1. Figure 1-4 In the middle, the upper end of the mounting cylinder 2 is usually sealed and covered by an upper end cover to facilitate the installation of the ultraviolet light-emitting component.
[0039] Because the temperature inside the dishwasher is higher during use, moisture may accumulate inside the mounting cylinder 2 over long-term use. The through-hole 24 connects the inner cavity of the mounting cylinder 2 to the outer space of the cabinet 1, achieving pressure balance inside and outside the mounting cylinder 2 and allowing air circulation. The upward-facing airflow allows humid air to escape, preventing moisture condensation inside the mounting cylinder 2.
[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.
