Description

Technical Field

[0001] This utility model belongs to the field of drying technology, and in particular relates to a low-power air-conditioning type heat pump drum dryer. Background Technology

[0002] Dryers are one of the most common devices used for drying items. A dryer mainly consists of four parts: the casing, the drum, the evaporator, and the condenser. The evaporator is used to quickly reduce the temperature of the water vapor in the dryer, causing it to condense and be collected. The condenser is used to heat the drum, thereby achieving the drying effect of the items inside the drum. The drum is used to carry the items and rotate them to ensure that the items are thoroughly dried.

[0003] Chinese patent application CN211400725U discloses an air-source heat pump air conditioner dryer and its control system, including an outdoor finned heat exchanger. An outdoor fan is installed on one side of the outdoor finned heat exchanger. The outdoor finned heat exchanger includes a finned tube sheet with a plurality of through holes evenly distributed on the finned tube sheet for inserting finned tubes or electric heating tubes. It has the following advantages: the arrangement of the outdoor fins can be adjusted according to the number of electric heating tubes without affecting the required heat dissipation area, and corresponding positions for the electric heating tubes are reserved; the electric heating tubes in the finned heat exchanger are evenly distributed, facilitating complete defrosting.

[0004] The aforementioned air-source heat pump air-conditioning dryer and its control system include an outdoor finned heat exchanger for rapid cooling of the unit. To prevent frost buildup, electric heating elements are inserted into the fins for defrosting. However, because the outdoor finned heat exchanger and heating elements are located on the outside of the dryer, the exposed structure makes them susceptible to damage during inspection or frostbite, posing a certain operational risk. Furthermore, the outdoor fins have several through holes into which the heating elements are inserted, meaning they are in direct contact with the fins. During operation, frost forms on the fins of the outdoor heat exchanger. Direct heating with the heating elements during this rapid temperature change can damage and embrittle the fins, drastically reducing their lifespan. Therefore, we provide a low-power air-conditioning type heat pump drum dryer to address these problems. Utility Model Content

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model provides a protective component, which is installed on the rear side wall of the machine body. The rear side wall of the machine body is inlaid with a condenser, fins, heating components, and evaporator. The protective plate in the protective component is located on the outside of the equipment, and the four corners of the protective plate are connected to the machine body by elastic elements. This achieves the effect of protecting the various equipment on the rear side wall of the machine body, and also prevents non-professionals from accidentally touching them.

[0018] 2. This utility model, by setting fins and a heating component, has fins installed on the outside of the evaporator to assist its operation. During normal operation, the evaporator will experience frost formation due to its low temperature. Since the fins are in direct contact with the evaporator and are used for temperature transfer and regulation, frost will also form on the fins. The fins are connected to the heating component, which generates heat through an electric heating plate during operation. A fan then blows this heat into the air supply duct, finally supplying hot air into the interior of each fin. This hot air travels through the serpentine heat dissipation grooves within the fins, completing a full path before exiting from the other end, thus achieving a defrosting effect. This non-contact defrosting method not only provides a superior defrosting effect but also ensures that the fins themselves retain their performance. Attached Figure Description

Detailed Implementation

[0030] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] Please see Figure 1-5 This utility model is a low-power air-conditioning type heat pump drum dryer. It includes a protective component 4 that can prevent the accessories on the dryer body 1 from being exposed, while ensuring that its heat dissipation and other performance are not affected, and also preventing accidental contact by others.

[0033] Specifically, a controller 2 and a cover 3 are installed on the front side wall of the machine body 1, and a protective component 4 is installed on the rear side wall of the machine body 1. The protective component 4 includes an elastic element 402 fixed on the machine body 1, and the machine body 1 is connected to the protective plate 401 through the elastic element 402. A cylindrical groove 101 is also provided inside the machine body 1, and the machine body 1 is connected to the roller 5 through the cylindrical groove 101. A drive groove 102 is provided on the side wall of the middle part of the cylindrical groove 101, and the machine body 1 is connected to the drive motor 503 through the drive groove 102. The motor shaft of the drive motor 503 is connected to the roller 5 for synchronous rotation through the belt 502. A fixed shaft hole 103 is provided in the rear side wall of the cylindrical groove 101, and the fixed shaft hole 103 is rotatably connected to the shaft on the rear side of the roller 5.

[0034] Furthermore, four elastic elements 402 are provided in total, and the four elastic elements 402 are respectively located at the four corners of the protective plate 401.

The first cylinder 402a is a hollow cylindrical structure with open ends, and the spring 402b is located inside the first cylinder 402a.

[0035] The operation process of this embodiment is as follows: When in use, the feed port end of the roller 5 is exposed when the cover 3 is opened. At this time, the items to be dried can be put into the roller 5. Then the cover 3 is closed, and the machine body 1 is started by the controller 2. The drive motor 503 works and drives the roller 5 to rotate through the belt 502. This causes the items to be dried in the roller 5 to tumble, ensuring that they are fully dried. When the staff or other personnel are located at the rear of the machine body 1, the protective plate 401 will first form a cavity barrier between the machine body 1 and the human body to prevent the human body from directly contacting the rear wall of the machine body 1. Even if the human body contacts the rear wall of the machine body 1, the elastic element 402 will be compressed first. At this time, the compression process can provide sufficient reaction time for the person who accidentally touches the machine body 1 to adjust their position.
