Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

As shown in fig. 4 and 5, the air duct base 16 of the present invention is formed with base ventilation holes 10 that communicate the upper side and the lower side of the air duct base.

In this technical solution, since the air duct base 16 is formed with the base vent 10 communicating the upper side and the lower side of the air duct base, after the air duct base 16 is applied to the clothes treatment device, the clothes drying part of the clothes treatment device can be disposed above the air duct base, and the clothes washing part of the clothes treatment device can be disposed below the air duct base, as shown in fig. 1, so that, in the casing of the clothes treatment device, the hot air in the external space of the clothes drying part can be communicated with the external space of the clothes washing part through the base vent on the air duct base for convection, so as to condense and cool the hot air through the external surface of the clothes washing part, thereby effectively reducing the temperature rise of the casing of the clothes treatment device.

The base vent 10 may be one large-sized opening, or, as shown in fig. 4, the base vent 10 may be plural and arranged in an array on the bottom wall portion of the duct base 16. In this way, the hot air of the external space of the laundry drying part and the external space of the laundry washing part can be made to form a circulation flow by the base vent holes 10 at a plurality of different positions.

As shown in fig. 5, a thickened region 49 is formed in the bottom wall portion of the duct base, and the base vent 10 is formed in the thickened region 49. In this way, thickened region 49 may increase the strength of the base of the tunnel to more stably and reliably support the upper, clothes drying portion.

In addition, in order to introduce the hot and humid air generated by drying the laundry in the laundry drying part of the laundry treating apparatus into the laundry washing part of the laundry treating apparatus through the exhaust passage for condensation, it is preferable that, as shown in fig. 5, a base exhaust groove 18 for forming an exhaust passage in cooperation with an upper cover exhaust groove 17 of the air duct upper cover 15 is formed on the bottom wall portion of the air duct base 16, an exhaust inlet 5 communicating with the upper side surface of the air duct base is formed at one end of the base exhaust groove 18, and an exhaust outlet 6 communicating with the lower side surface of the air duct base is formed at the other end of the base exhaust groove 18. Thus, when the duct upper cover 15 is disposed on the duct base 16, the upper cover exhaust groove 17 and the base exhaust groove 18 form an exhaust passage that is a part of the exhaust passage.

Further, as shown in fig. 2 to 5, the exhaust inlet 5 extends downward from the upper end surface of the side wall portion 19 of the duct base 16, and communicates with the base exhaust groove 18 through the vent hole 20 formed on the inner side surface of the side wall portion 19. Thus, after the first cylinder 1 is arranged on the air channel supporting seat 4, the exhaust inlet 5 is more convenient to be communicated with the end part of the first inner cavity of the first cylinder 1.

As shown in fig. 5, an air duct upper cover support flange 50 surrounding the air vent 20 is formed on the inner side surface of the side wall portion 19. The duct cover support flange 50 can position and support the duct cover.

Furthermore, in order to dry the clothes by sending the air condensed by the clothes washing part into the air heating unit through the air inlet passage to be heated again and then introducing the air into the clothes drying part, it is preferable that as shown in fig. 3 and 4, a base inlet groove 23 is formed on the bottom wall portion of the duct base 16, and an inlet opening 7 communicating with the lower side surface of the duct base is formed on the bottom of the base inlet groove 23; the base inlet groove 23 is isolated from the base outlet groove 18. Thus, after the air duct upper cover and the air duct end cover are matched with the air duct base, an upper cover part air inlet groove 22 with an air inlet outlet 8 is formed between the air duct upper cover and the air duct end cover, and the upper cover part air inlet groove 22 and the base air inlet groove 23 form an air inlet channel. The intake passage serves as a part of an intake passage.

Further, in order to facilitate the rapid introduction of the intake air in the intake passage into the gas heating unit, it is preferable that, as shown in fig. 5, a base fan receiving groove 28 is formed on a bottom wall portion of the duct base 16, the base fan receiving groove 28 is located outside an outer side groove side wall 47 of the base intake groove 23 and shares the outer side groove side wall 47, and the base fan receiving groove 28 communicates with the base intake groove 23. And the air duct end cover 21 includes an end cover fan receiving groove 27 and an air outlet 25, the air duct end cover 21 is covered on the air duct base 16, so that the end cover fan receiving groove 27 and the base fan receiving groove 28 form a fan receiving cavity 26 with the air outlet 25, the fan receiving cavity 26 and the air inlet channel share the outer channel wall of the air inlet channel, and the air inlet outlet 8 is formed on the outer channel wall. In this way, the fan disposed in the fan receiving chamber 26 can guide the intake air to flow out of the intake passage and into the gas heating unit quickly.

Further, as shown in fig. 5, a motor mounting cavity 51 is formed on the bottom wall portion of the air duct base 16, the motor mounting cavity 51 is located inside an inner side slot side wall 57 of the base air inlet slot 23 and shares the inner side slot side wall 57, the motor mounting cavity 51 is communicated with the base air inlet slot 23, for example, a through hole is formed on the air inlet casing side wall 38 of the air duct upper cover, so that the motor can be disposed in the motor mounting cavity 51, and an output shaft of the motor can pass through the through hole on the air inlet casing side wall 38, pass through the air inlet channel, and pass through the air inlet outlet 8 to be connected with the fan disposed in the fan accommodating cavity 26 to drive the fan.

Additionally, the inner slot walls 46 of the end cap fan receiving slots 27 of the air inlet housing portion side walls 38 and air duct end cap 21 described above may have any configuration and cooperate with the inner slot side walls 57 and outer slot side walls 47 of the base air inlet slots 23 on the air duct base 16 to form the inner and outer channel walls of the air inlet channel. For example, as shown in fig. 2, 3, 6 and 7, the lower portion of the inlet casing side wall 38 and the lower portion of the inner slot wall 46 are formed with semicircular projections 41, while the upper surfaces of the inner slot side wall 57 and the outer slot side wall 47 of the base inlet slot 23 are formed with semicircular recesses 40, so that the semicircular projections 41 can fit within the semicircular recesses 40 and be retained by the semicircular recesses 40.

And/or the presence of a gas in the gas,

in addition, the duct base includes sealing ribs and/or sealing grooves 48 formed on the upper surfaces of the duct upper cover support flanges 50, the sidewalls of the base exhaust slot 18, and the sidewalls of the base inlet slot 23 that extend around the base exhaust slot 18 and the base inlet slot 23. Thus, as shown in FIG. 5, the duct upper cover 24 can be attached to the duct base along the sealing ribs and/or sealing grooves 48. Thus, as shown in FIG. 5, the duct upper cover 24 formed by the duct upper cover and the duct end cap can be closed onto the duct base along the sealing ribs and/or sealing grooves 48.

Further, the present invention provides a laundry treating apparatus, as shown in fig. 1, comprising a laundry drying part communicating with the laundry washing part through an exhaust passage, a laundry washing part communicating with the gas heating unit through an intake passage, and a gas heating unit communicating with the laundry drying part; a space between the case of the laundry treating apparatus and the laundry drying part is communicated with a space between the case of the laundry treating apparatus and the laundry washing part.

Further, the laundry treating device comprises the duct base as described in any of the above, wherein a space between the casing of the laundry treating device and the laundry drying part is communicated with a space between the casing of the laundry treating device and the laundry washing part through a base vent hole on the duct base.

Further, the laundry treating apparatus provided by the present invention may have any structure, which is not limited to the specific structure shown in the drawings.

Therefore, a structure of the laundry treating apparatus will be described in detail below with reference to the accompanying drawings, specifically:

Because the first inner cavity is communicated with the second inner cavity of the second barrel body 2 through the exhaust passage, the second inner cavity of the second barrel body 2 is communicated with the gas heating unit through the air inlet passage, and the gas heating unit is communicated with the first inner cavity, in this way, hot air heated by the gas heating unit enters the first inner cavity to dry wet clothes, wet hot air generated by drying the wet clothes enters the second barrel body through the exhaust passage, after the wet hot air is condensed through the inner surface of the second barrel body or the washing drum (when the washing drum is arranged in the second barrel body), the wet hot air enters the gas heating unit through the air inlet passage to be reheated and then enters the first inner cavity to dry the clothes, thereby realizing the circulating flow of the air, avoiding the direct discharge of the wet hot air, avoiding the wet heat of the indoor air environment, and improving the indoor comfort to a certain degree. In addition, the overall quality and user experience of the clothes treatment device are remarkably improved.

Of course, it should be understood herein that the present invention provides the laundry treating apparatus, wherein the first drum 1 may be used as a drying tub, or may be used as a washing tub, and the second drum 2 may be used as a washing tub; in addition, the first cylinder 1 can be directly used as a drying tub or a washing tub, or the first cylinder 1 can be used as a drying outer tub or a washing outer tub, and a drying drum or a washing drum is arranged in the first cylinder; the second tub 2 may be directly used as a washing tub, or the second tub 2 may be used as a washing tub, and a washing drum is further provided therein.

For example, in order to improve the washing effect of the clothes and improve the condensation surface and condensation effect of the hot and humid air in the second cylinder 2, preferably, as shown in fig. 1, a washing drum 3 is disposed in the second inner cavity of the second cylinder 2, so that the hot and humid air, after entering the second inner cavity, will contact the inner circumferential surface of the second cylinder 2 and the inner and outer circumferential surfaces of the washing drum 3 and be condensed by the second cylinder 2 and the washing drum 3, which increases the condensation surface and improves the condensation effect, and water molecules in the hot and humid air are more easily condensed, and at the same time, when the washing drum 3 rotates, the hot and humid air is more easily driven to collide with the inner circumferential surface of the second cylinder 2 and the inner and outer circumferential surfaces of the washing drum 3 for condensation, and at the same time, the air is more easily driven to flow into the air inlet passage; and/or, in the height direction of the laundry treating apparatus, the first tub 1 is disposed above and the second tub 2 is disposed below, as in the structure shown in fig. 1, such that the first and second tubs 1 and 2 are arranged up and down and disposed within the casing of the laundry treating apparatus, thereby forming a dual tub washing and drying machine.

Of course, alternatively, the first drum 1 and the second drum 2 may be arranged left and right and provided within the casing of the laundry treating apparatus; alternatively, the first cylinder 1 and the second cylinder 2 may be provided in separate devices and may be communicated with the intake passage through the exhaust passage.

In addition, regardless of whether the first cylinder 1 and the second cylinder 2 are arranged up and down or left and right, further, the laundry treating apparatus includes an air duct support 4, the first cylinder 1 is disposed on the air duct support 4, and in the structure shown in fig. 1, the first cylinder 1 and the second cylinder 2 are arranged up and down, and the second cylinder 2 is disposed below the air duct support 4, wherein the air duct support 4 includes an isolated exhaust passage and an intake passage, the exhaust passage forms a part of an exhaust passage, the intake passage forms a part of an intake passage, wherein an exhaust inlet 5 at one end of the exhaust passage communicates with a first inner cavity in the first cylinder 1, and an exhaust outlet 6 at the other end of the exhaust passage communicates with a second inner cavity of the second cylinder 2; and a gas inlet 7 at one end of the gas inlet channel is communicated with the second inner cavity of the second cylinder 2, and a gas outlet 8 at the other end of the gas inlet channel is communicated with the gas heating unit.

Thus, the first cylinder 1 can be supported and positioned through the air duct supporting seat 4. For example, the existing base of the clothes dryer can be utilized, and the air inlet and the air outlet of the clothes dryer are both arranged on the base to form the air duct supporting seat 4, so that the first cylinder 1 of the clothes dryer is prevented from being provided with other holes.

Further, in order to enhance the condensation effect of the hot and humid air, the exhaust passage is provided with a cooling structure for condensing the hot and humid air flowing in the exhaust passage. For example, in one embodiment, a cooling structure is provided on a channel wall of the exhaust channel for cooling the gas flowing through the exhaust channel.
